Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).
storage/maria/ha_maria.cc:
in ha_maria::backup, need to flush the data file before copying it,
otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
when allocating data at the end of the bitmap, best_data is at "end",
should not be left to 0 (bug 2)
storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).

storage/maria/ma_range.c:

storage/maria/ma_rename.c:

- update create_rename_lsn
- we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
comment
storage/maria/ma_test_all.sh:
- tip for Valgrind-ing ma_test_all
- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:
using most significant byte of first_undo_lsn to hold miscellaneous
flags, for now TRANSACTION_LOGGED_LONG_ID.
dummy_transaction_object is already declared in ma_static.c.
storage/maria/trnman_public.h:
dummy_transaction_object was declared in all files including
trnman_public.h, while in fact it's a single object.

.tree-is-private:
this file is now needed to keep our tree private (don't push it
to public trees). When 5.1 is merged into mysql-maria, we can abandon
our maria-specific post-commit trigger; .tree_is_private will take
care of keeping commit mails private. Don't push this file to public
trees.

(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).
storage/maria/ma_pagecache.h:
see ma_pagecache.c
storage/maria/ma_panic.c:
comment
storage/maria/ma_range.c:
comment
storage/maria/ma_rename.c:
- logging LOGREC_RENAME_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- update create_rename_lsn
- we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
comment
storage/maria/ma_test_all.sh:
- tip for Valgrind-ing ma_test_all
- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:
using most significant byte of first_undo_lsn to hold miscellaneous
flags, for now TRANSACTION_LOGGED_LONG_ID.
dummy_transaction_object is already declared in ma_static.c.
storage/maria/trnman_public.h:
dummy_transaction_object was declared in all files including
trnman_public.h, while in fact it's a single object.
new prototype
storage/maria/unittest/ma_test_loghandler-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_multigroup-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_multithread-t.c:
update for new prototype
storage/maria/unittest/ma_test_loghandler_pagecache-t.c:
update for new prototype
storage/maria/ma_commit.c:
function which wraps:
- writing a LOGREC_COMMIT record (==commit on disk)
- calling trnman_commit_trn() (=commit in memory)
storage/maria/ma_commit.h:
new header file
.tree-is-private:
this file is now needed to keep our tree private (don't push it
to public trees). When 5.1 is merged into mysql-maria, we can abandon
our maria-specific post-commit trigger; .tree_is_private will take
care of keeping commit mails private. Don't push this file to public
trees.

storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:

storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed

Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
storage/maria/ma_info.c:
Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG
storage/maria/ma_page.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- Modify share->state.state.key_file_length under share->intern_lock

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
info->s -> share

Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions
- Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.
- Added virtual function lock_restore_status
Changes to MARIA_HA:

WL#3138: Maria - fast "SELECT COUNT(*) FROM t;" and "CHECKSUM TABLE t"
Added argument to maria_end_bulk_insert() to know if the table will be deleted after the operation
Fixed wrong call to strmake
Don't call bulk insert in case of inserting only one row (speed optimization as starting/stopping bulk insert
Allow storing year 2155 in year field
When running with purify/valgrind avoid copying structures over themself
Added hook 'trnnam_end_trans_hook' that is called when transaction ends
Added trn->used_tables that is used to an entry for all tables used by transaction
Fixed that ndb doesn't crash on duplicate key error when start_bulk_insert/end_bulk_insert are not called
include/maria.h:
Added argument to maria_end_bulk_insert() to know if the table will be deleted after the operation
include/my_tree.h:

Added new argument to end_bulk_insert()
storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum
Keep share->state.state.data_file_length up to date (not info->state->data_file_length)

info->s to share
Update info->state at end of repair
Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
storage/maria/ma_info.c:
Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG
storage/maria/ma_page.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- Modify share->state.state.key_file_length under share->intern_lock

storage/maria/ma_write.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/maria_def.h:
Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions
- Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.
- Added virtual function lock_restore_status
Changes to MARIA_HA:
- save_state -> state_save

Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid
Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements
- HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
- Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it
.bzrignore:
Added missing temporary directory
extra/Makefile.am:
comp_err is now deleted on make distclean
include/maria.h:
Added structure MARIA_KEY, which is used for intern key objects in Maria.
Changed functions to take MARIA_KEY as an argument instead of pointer to packed key.
Changed some functions that always return true or false to my_bool.
Added virtual function make_key() to avoid if in _ma_make_key()
Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster
include/my_base.h:
Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check()
Added SEARCH_INSERT to be used when inserting new keys
Added SEARCH_PART_KEY for partial searches
Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID
Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid
include/my_handler.h:
Make next_flag 32 bit to make sure we can handle all SEARCH_ bits
mysql-test/include/maria_empty_logs.inc:
Read and restore current database; Don't assume we are using mysqltest.
Don't log use databasename to log. Using this include should not cause any result changes.
mysql-test/r/maria-gis-rtree-dynamic.result:
Updated results after adding some check table commands to help pinpoint errors

Don't log id as it's not predictable
mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb_2.result:
Updated results to new binlog results. (Test has not been run in a long time as it requires --big)
mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2-master.opt:
Moved file to ndb replication test directory
mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2.test:
Fixed wrong path to included tests
mysql-test/t/maria-gis-rtree-dynamic.test:

mysql-test/t/maria.test:
New tests for some possible problems
mysql-test/t/variables-big.test:
Don't log id as it's not predictable
mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag
mysys/my_lock.c:
Fixed wrong test (Found by Guilhem)
scripts/Makefile.am:
Ensure that test programs are deleted by make clean
sql/rpl_rli.cc:
Moved assignment order to fix compiler warning
storage/heap/hp_write.c:
Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
storage/maria/Makefile.am:
Remove also maria log files when doing make distclean
storage/maria/ha_maria.cc:
Use 'file->start_state' as default state for transactional tables without versioning
At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
Updated comment
storage/maria/ma_check.c:
Compact key pages (removes transid) when doing --zerofill
Check that 'page_flag' on key pages contains KEYPAGE_FLAG_HAS_TRANSID if there is a single key on the page with a transid
Modified functions to use MARIA_KEY instead of key pointer and key length
Use new interface to _ma_rec_pos(), _ma_dpointer(), _ma_ft_del(), ma_update_state_lsn()
Removed not needed argument from get_record_for_key()
Fixed that we check doesn't give errors for RTREE; We now treath these like SPATIAL
Remove some SPATIAL specific code where the virtual functions can handle this in a general manner
Use info->lastkey_buff instead of info->lastkey
_ma_dpos() -> _ma_row_pos_from_key()
_ma_make_key() -> keyinfo->make_key()
_ma_print_key() -> _ma_print_keydata()
_ma_move_key() -> ma_copy_copy()
Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
Ensure that data on page doesn't overwrite page checksum position
Use DBUG_DUMP_KEY instead of DBUG_DUMP
Use exact key lengths instead of USE_WHOLE_KEY to ha_key_cmp()
Fixed check if rowid points outside of BLOCK_RECORD data file
Use info->lastkey_buff instead of key on stack in some safe places
Added #fdef EXTERNAL_LOCKING around removed state elements
storage/maria/ma_close.c:
Use keyinfo->root_lock instead of share->key_root_lock[keynr]
storage/maria/ma_create.c:
Removed assert that is already checked in maria_init()
Force transactinal tables to be of type BLOCK_RECORD
Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD)
Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
storage/maria/ma_dbug.c:
Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
Modified functions to use MARIA_KEY instead of key pointer and key length
info->lastkey2-> info->lastkey_buff2
Added SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
Use new interface for get_key(), _ma_get_last_key() and others
_ma_dpos() -> ma_row_pos_from_key()

Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid
Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements
- HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
- Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it

Added SEARCH_INSERT to be used when inserting new keys
Added SEARCH_PART_KEY for partial searches

mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit

At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave

Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid
Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements

mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND

Use 'file->start_state' as default state for transactional tables without versioning
At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave

Added new index page operations
storage/maria/ma_open.c:

Don't log id as it's not predictable
mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag
mysys/my_lock.c:
Fixed wrong test (Found by Guilhem)
scripts/Makefile.am:
Ensure that test programs are deleted by make clean
sql/rpl_rli.cc:
Moved assignment order to fix compiler warning
storage/heap/hp_write.c:
Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
storage/maria/Makefile.am:
Remove also maria log files when doing make distclean
storage/maria/ha_maria.cc:
Use 'file->start_state' as default state for transactional tables without versioning
At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
Updated comment
storage/maria/ma_check.c:
Compact key pages (removes transid) when doing --zerofill
Check that 'page_flag' on key pages contains KEYPAGE_FLAG_HAS_TRANSID if there is a single key on the page with a transid
Modified functions to use MARIA_KEY instead of key pointer and key length
Use new interface to _ma_rec_pos(), _ma_dpointer(), _ma_ft_del(), ma_update_state_lsn()
Removed not needed argument from get_record_for_key()
Fixed that we check doesn't give errors for RTREE; We now treath these like SPATIAL
Remove some SPATIAL specific code where the virtual functions can handle this in a general manner
Use info->lastkey_buff instead of info->lastkey
_ma_dpos() -> _ma_row_pos_from_key()

Fixed check if rowid points outside of BLOCK_RECORD data file
Use info->lastkey_buff instead of key on stack in some safe places

Force transactinal tables to be of type BLOCK_RECORD
Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD)
Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
storage/maria/ma_dbug.c:
Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
Modified functions to use MARIA_KEY instead of key pointer and key length

Added new index page operations
storage/maria/ma_open.c:
Removed allocated "state_dummy" and instead use share->state.common for transactional tables that are not versioned
This is needed to not get double increments of state.records (one in ma_write.c and on when log is written)
Changed info->lastkey to MARIA_KEY type
Removed resetting of MARIA_HA variables that have 0 as default value (as info is zerofilled)
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.

If there may be keys with transid on the page, have _ma_bin_search() call _ma_seq_search()
Add _ma_skip_xxx() functions to quickly step over keys (faster than calling get_key() in most cases as we don't have to copy key data)
Combine similar code at end of _ma_get_binary_pack_key()
Removed not used function _ma_move_key()
In _ma_search_next() don't call _ma_search() if we aren't on a nod page.
Update info->cur_row.trid with trid for found key
Removed some not needed casts
Added _ma_trid_from_key()

- WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into
the header of the index file). For that, state.is_of_lsn is introduced;
logic is explained in ma_recovery.c (look for "Recovery of the state").
The net gain is that in case of crash, we now recover state.records,
and it is idempotent (ma_test_recovery tests it).
state.checksum is not recovered yet, mail sent for discussion.
- WL#3071 Maria Checkpoint: preparation for it, by protecting
all modifications of the state in memory or on disk with intern_lock
(with the exception of the really-often-modified state.records,
which is now protected with the log's lock, see ma_recovery.c
(look for "Recovery of the state"). Also, if maria_close() sees that
Checkpoint is looking at this table it will not my_free() the share.
- don't compute row's checksum twice in case of UPDATE (correction
to a bugfix I made yesterday).
storage/maria/ha_maria.cc:
protect state write with intern_lock (against Checkpoint)
storage/maria/ma_blockrec.c:
* don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it
should wait until we have corrected the allocation in the bitmap
(as the REDO can serve to correct the allocation during Recovery);
introducing _ma_finalize_row() for that.
* In a changeset yesterday I moved computation of the checksum
into write_block_record(), to fix a bug in UPDATE. Now I notice
that maria_update() already computes the checksum, it's just that
it puts it into info->cur_row while _ma_update_block_record()
uses info->new_row; so, removing the checksum computation from
write_block_record(), putting it back into allocate_and_write_block_record()
(which is called only by INSERT and UNDO_DELETE), and copying
cur_row->checksum into new_row->checksum in _ma_update_block_record().
storage/maria/ma_check.c:
new prototypes, they will take intern_lock when writing the state;
also take intern_lock when changing share->kfile. In both cases
this is to protect against Checkpoint reading/writing the state or reading
kfile at the same time.
Not updating create_rename_lsn directly at end of write_log_record_for_repair()
as it wouldn't have intern_lock.
storage/maria/ma_close.c:
Checkpoint builds a list of shares (under THR_LOCK_maria), then it
handles each such share (under intern_lock) (doing flushing etc);
if maria_close() freed this share between the two, Checkpoint
would see a bad pointer. To avoid this, when building the list Checkpoint
marks each share, so that maria_close() knows it should not free it
and Checkpoint will free it itself.
Extending the zone covered by intern_lock to protect against
Checkpoint reading kfile, writing state.
storage/maria/ma_create.c:
When we update create_rename_lsn, we also update is_of_lsn to
the same value: it is logical, and allows us to test in maria_open()
that the former is not bigger than the latter (the contrary is a sign
of index header corruption, or severe logging bug which hinders
Recovery, table needs a repair).
_ma_update_create_rename_lsn_on_disk() also writes is_of_lsn;
it now operates under intern_lock (protect against Checkpoint),
a shortcut function is available for cases where acquiring
intern_lock is not needed (table's creation or first open).
storage/maria/ma_delete.c:
if table is transactional, "records" is already decremented
when logging UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
comments
storage/maria/ma_extra.c:
Protect modifications of the state, in memory and/or on disk,
with intern_lock, against a concurrent Checkpoint.
When state goes to disk, update it's is_of_lsn (by calling
the new _ma_state_info_write()).
In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing
a change I made a few days ago) and ASK_MONTY
storage/maria/ma_locking.c:
no real code change here.
storage/maria/ma_loghandler.c:
Log-write-hooks for updating "state.records" under log's mutex
when writing/updating/deleting a row or deleting all rows.
storage/maria/ma_loghandler_lsn.h:
merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different)
storage/maria/ma_open.c:
When opening a table verify that is_of_lsn >= create_rename_lsn; if
false the header must be corrupted.
_ma_state_info_write() is split in two: _ma_state_info_write_sub()
which is the old _ma_state_info_write(), and _ma_state_info_write()
which additionally takes intern_lock if requested (to protect
against Checkpoint) and updates is_of_lsn.
_ma_open_keyfile() should change kfile.file under intern_lock
to protect Checkpoint from reading a wrong kfile.file.
storage/maria/ma_recovery.c:
Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT
which has a LSN > state.is_of_lsn it increments state.records.
Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE.
When closing a table during Recovery, we know its state is at least
as new as the current log record we are looking at, so increase
is_of_lsn to the LSN of the current log record.
storage/maria/ma_rename.c:
update for new behaviour of _ma_update_create_rename_lsn_on_disk().
storage/maria/ma_test1.c:
update to new prototype
storage/maria/ma_test2.c:
update to new prototype (actually prototype was changed days ago,
but compiler does not complain about the extra argument??)
storage/maria/ma_test_recovery.expected:
new result file of ma_test_recovery. Improvements: record
count read from index's header is now always correct.
storage/maria/ma_test_recovery:
"rm" fails if file does not exist. Redirect stderr of script.
storage/maria/ma_write.c:
if table is transactional, "records" is already incremented when
logging UNDO_ROW_INSERT. Comments.
storage/maria/maria_chk.c:
update is_of_lsn too
storage/maria/maria_def.h:
- MARIA_STATE_INFO::is_of_lsn which is used by Recovery. It is stored
into the index file's header.
- Checkpoint can now mark a table as "don't free this", and maria_close()
can reply "ok then you will free it".
- new functions
storage/maria/maria_pack.c:
update for new name

storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed

Versioning of count(*) and checksum:
- Use share->state.state instead of info->state

info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG

- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

- WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into
the header of the index file). For that, state.is_of_lsn is introduced;
logic is explained in ma_recovery.c (look for "Recovery of the state").
The net gain is that in case of crash, we now recover state.records,
and it is idempotent (ma_test_recovery tests it).
state.checksum is not recovered yet, mail sent for discussion.
- WL#3071 Maria Checkpoint: preparation for it, by protecting
all modifications of the state in memory or on disk with intern_lock
(with the exception of the really-often-modified state.records,
which is now protected with the log's lock, see ma_recovery.c
(look for "Recovery of the state"). Also, if maria_close() sees that
Checkpoint is looking at this table it will not my_free() the share.
- don't compute row's checksum twice in case of UPDATE (correction
to a bugfix I made yesterday).
storage/maria/ha_maria.cc:
protect state write with intern_lock (against Checkpoint)
storage/maria/ma_blockrec.c:
* don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it
should wait until we have corrected the allocation in the bitmap
(as the REDO can serve to correct the allocation during Recovery);
introducing _ma_finalize_row() for that.
* In a changeset yesterday I moved computation of the checksum
into write_block_record(), to fix a bug in UPDATE. Now I notice
that maria_update() already computes the checksum, it's just that
it puts it into info->cur_row while _ma_update_block_record()
uses info->new_row; so, removing the checksum computation from
write_block_record(), putting it back into allocate_and_write_block_record()
(which is called only by INSERT and UNDO_DELETE), and copying
cur_row->checksum into new_row->checksum in _ma_update_block_record().
storage/maria/ma_check.c:
new prototypes, they will take intern_lock when writing the state;
also take intern_lock when changing share->kfile. In both cases
this is to protect against Checkpoint reading/writing the state or reading
kfile at the same time.
Not updating create_rename_lsn directly at end of write_log_record_for_repair()
as it wouldn't have intern_lock.
storage/maria/ma_close.c:
Checkpoint builds a list of shares (under THR_LOCK_maria), then it
handles each such share (under intern_lock) (doing flushing etc);
if maria_close() freed this share between the two, Checkpoint
would see a bad pointer. To avoid this, when building the list Checkpoint
marks each share, so that maria_close() knows it should not free it
and Checkpoint will free it itself.
Extending the zone covered by intern_lock to protect against
Checkpoint reading kfile, writing state.
storage/maria/ma_create.c:
When we update create_rename_lsn, we also update is_of_lsn to
the same value: it is logical, and allows us to test in maria_open()
that the former is not bigger than the latter (the contrary is a sign
of index header corruption, or severe logging bug which hinders
Recovery, table needs a repair).
_ma_update_create_rename_lsn_on_disk() also writes is_of_lsn;
it now operates under intern_lock (protect against Checkpoint),
a shortcut function is available for cases where acquiring
intern_lock is not needed (table's creation or first open).
storage/maria/ma_delete.c:
if table is transactional, "records" is already decremented
when logging UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
comments
storage/maria/ma_extra.c:
Protect modifications of the state, in memory and/or on disk,
with intern_lock, against a concurrent Checkpoint.
When state goes to disk, update it's is_of_lsn (by calling
the new _ma_state_info_write()).
In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing
a change I made a few days ago) and ASK_MONTY
storage/maria/ma_locking.c:
no real code change here.
storage/maria/ma_loghandler.c:
Log-write-hooks for updating "state.records" under log's mutex
when writing/updating/deleting a row or deleting all rows.
storage/maria/ma_loghandler_lsn.h:
merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different)
storage/maria/ma_open.c:
When opening a table verify that is_of_lsn >= create_rename_lsn; if
false the header must be corrupted.
_ma_state_info_write() is split in two: _ma_state_info_write_sub()
which is the old _ma_state_info_write(), and _ma_state_info_write()
which additionally takes intern_lock if requested (to protect
against Checkpoint) and updates is_of_lsn.
_ma_open_keyfile() should change kfile.file under intern_lock
to protect Checkpoint from reading a wrong kfile.file.
storage/maria/ma_recovery.c:
Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT
which has a LSN > state.is_of_lsn it increments state.records.
Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE.
When closing a table during Recovery, we know its state is at least
as new as the current log record we are looking at, so increase

case HA_EXTRA_FORCE_REOPEN:
|
- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static

- speed optimization:
minimize writes to transactional Maria tables: don't write

we thus should avoid to read it from disk.

- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)

storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

This share, to have last_version=0, needs to save all its data/index
|
- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).

it was pointless for a recovered table

probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records

as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).

- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).

storage/maria/ma_static.c:

- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark

update for new prototype
storage/maria/unittest/ma_test_loghandler_pagecache-t.c:
update for new prototype
storage/maria/ma_commit.c:
function which wraps:
- writing a LOGREC_COMMIT record (==commit on disk)
- calling trnman_commit_trn() (=commit in memory)
storage/maria/ma_commit.h:
new header file
.tree-is-private:
this file is now needed to keep our tree private (don't push it
to public trees). When 5.1 is merged into mysql-maria, we can abandon
our maria-specific post-commit trigger; .tree_is_private will take
care of keeping commit mails private. Don't push this file to public
trees.

- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.
storage/maria/Makefile.am:
more files to build
storage/maria/ha_maria.cc:
- logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
- ha_maria::data_file_type does not have to be set in every info()
call, just do it once in open().
- if caller said that transactionality can be disabled (like if
caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
temporarily disable transactionality of the table in external_lock();
that will ensure that no REDOs/UNDOs are logged for this possibly
massive write operation (they are not needed, as if any write fails,
the table will be dropped). We re-enable in external_lock(F_UNLCK),
which in ALTER TABLE happens before the tmp table replaces the original
one (which is good, as thus the final table will have a REDO RENAME
and a correct create_rename_lsn).
- when we commit we also have to write a log record, so
trnman_commit_trn() calls become ma_commit() calls
- at end of engine's initialization, we are potentially entering a
multi-threaded dangerous world (clients are going to be accepted)
and so some assertions of mutex-owning become enforceable, for that
we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
- fixing comments according to discussion with Monty
- if a table is transactional but temporarily non-transactional
(like in ALTER TABLE), we need to give a sensible LSN to the pages
(and, if we give 0, pagecache asserts).
- translog_write_record() now takes care of storing the share's
2-byte-id in the log record
storage/maria/ma_blockrec.h:
fixing comment according to discussion with Monty
storage/maria/ma_check.c:
When REPAIR/OPTIMIZE modify the data/index file, if this is a
transactional table, they must sync it; if they remove files or rename
files, they must sync the directory, so that everything is durable.
This is just applying to REPAIR/OPTIMIZE the logic already implemented
in CREATE/DROP/RENAME a few months ago.
Adding a function to write a LOGREC_REPAIR_TABLE at end of
REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
to update the table's create_rename_lsn.
storage/maria/ma_close.c:
fix for a future bug
storage/maria/ma_control_file.c:
ensuring that if Maria is running in multi-threaded mode, anybody
wanting to write to the control file and update
last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
see ma_control_file.c
storage/maria/ma_create.c:
when creating a table:
- sync it and its directory only if this is a transactional table
and there is a log (no point in syncing in maria_chk)
- decouple the two uses of linkname/linkname_ptr (for index file and
for data file) into more variables, as we need to know all links
until the moment we write the LOGREC_CREATE_TABLE.
- set share.data_file_type early so that _ma_initialize_data_file()
knows it (Monty's bugfix so that a table always has at least a bitmap
page when it is created; so data-file is not 0 bytes anymore).
- log a LOGREC_CREATE_TABLE; it contains the bytes which we have
just written to the index file's header. Update table's
create_rename_lsn.
- syncing of kfile had been bugified in a previous merge, correcting
- syncing of dfile is now needed as it's not empty anymore
- in _ma_initialize_data_file(), use share's block_size and not the
global one. This is a gratuitous change, both variables are equal,
just that I find it more future-proof to use share-bound variable
rather than global one.
storage/maria/ma_delete_all.c:
log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
update create_rename_lsn then.
storage/maria/ma_delete_table.c:
- logging LOGREC_DROP_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the
table.
- we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
questions
storage/maria/ma_init.c:
when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
- translog_inited has to be visible to ma_create() (see how it is used
in ma_create())
- checkpoint record will be a single record, not three
- no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
log a REDO_CREATE)
- adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
truncating the files), REPAIR.
- MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
- in translog_write_record(), if MARIA_SHARE does not yet have a
2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
store this short id into log records.
- in translog_write_record(), if transaction has not logged its
long trid, log LOGREC_LONG_TRANSACTION_ID.
- For Checkpoint, we need to know the current end-of-log: adding
translog_get_horizon().
- For Control File, adding an assertion that the thread owns the
log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
Changes in log records (see ma_loghandler.c).
new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
where the most significant byte is used for flags.
storage/maria/ma_open.c:
storing the create_rename_lsn in the index file's header (in the
state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
- my set_if_bigger was wrong, correcting it
- if the first_in_switch list is not empty, it means that
changed_blocks misses some dirty pages, so Checkpoint cannot run and
needs to wait. A variable missing_blocks_in_changed_list is added to
tell that (should it be named missing_blocks_in_changed_blocks?)
- pagecache_collect_changed_blocks_with_lsn() now also tells the
minimum rec_lsn (needed for low-water mark computation).

storage/maria/ma_panic.c:
comment
storage/maria/ma_range.c:
comment
storage/maria/ma_rename.c:
- logging LOGREC_RENAME_TABLE; knowing if this is needed, requires
knowing if the table is transactional, which requires opening the

- update create_rename_lsn
- we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
comment
storage/maria/ma_test_all.sh:
- tip for Valgrind-ing ma_test_all
- do "export maria_path=somepath" before calling ma_test_all,
if you want to run ma_test_all out of storage/maria (useful
to have parallel runs, like one normal and one Valgrind, they
must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
- state now contains, in memory and on disk, the create_rename_lsn
- share now contains a 2-byte-id
storage/maria/trnman.c:
preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:

care of keeping commit mails private. Don't push this file to public

Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean

As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional

storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;

external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables

Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records

WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)
BitKeeper/deleted/.del-ma_least_recently_dirtied.c:
Delete: storage/maria/ma_least_recently_dirtied.c
BitKeeper/deleted/.del-ma_least_recently_dirtied.h:
Delete: storage/maria/ma_least_recently_dirtied.h
storage/maria/Makefile.am:
compile Checkpoint module
storage/maria/ha_maria.cc:
When ha_maria starts, do a recovery from last checkpoint.
Take a checkpoint when that recovery has ended and when ha_maria
shuts down cleanly.
storage/maria/ma_blockrec.c:
* even if my_sync() fails we have to my_close() (otherwise we leak
a descriptor)
* UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
as promised in the old comment; it gives us skipping during the
UNDO phase.
storage/maria/ma_check.c:
All REDOs before create_rename_lsn are ignored by Recovery. So
create_rename_lsn must be set only after all data/index has been
flushed and forced to disk. We thus move write_log_record_for_repair()
to after _ma_flush_tables_files_after_repair().
storage/maria/ma_checkpoint.c:
Checkpoint module.
storage/maria/ma_checkpoint.h:
optional argument if caller wants a thread to periodically take
checkpoints and flush dirty pages.
storage/maria/ma_create.c:
* no need to init some vars as the initial bzero(share) takes care of this.
* update to new function's name
* even if we fail in my_sync() we have to my_close()
storage/maria/ma_extra.c:
Checkpoint reads share->last_version under intern_lock, so we make
maria_extra() update it under intern_lock. THR_LOCK_maria still needed
because of _ma_test_if_reopen().
storage/maria/ma_init.c:
destroy checkpoint module when Maria shuts down.
storage/maria/ma_loghandler.c:
* UNDO_ROW_PURGE gone (see ma_blockrec.c)
* we need to remember the LSN of the LOGREC_FILE_ID for a share,
because this LSN is needed into the checkpoint record (Recovery wants
to know the validity domain of an id->name mapping)
* translog_get_horizon_no_lock() needed for Checkpoint
* comment about failing assertion (Sanja knows)
* translog_init_reader_data() thought that translog_read_record_header_scan()
returns 0 in case of error, but 0 just means "0-length header".
* translog_assign_id_to_share() now needs the MARIA_HA because
LOGREC_FILE_ID uses a log-write hook.
* Verify that (de)assignment of share->id happens only under intern_lock,
as Checkpoint reads this id with intern_lock.
* translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
a real LSN.
storage/maria/ma_loghandler.h:
prototype updates
storage/maria/ma_open.c:
no need to initialize "res"
storage/maria/ma_pagecache.c:
When taking a checkpoint, we don't need to know the maximum rec_lsn
of dirty pages; this LSN was intended to be used in the two-checkpoint
rule, but last_checkpoint_lsn is as good.
4 bytes for stored_list_size is enough as PAGECACHE::blocks (number
of blocks which the pagecache can contain) is int.
storage/maria/ma_pagecache.h:
new prototype
storage/maria/ma_recovery.c:
* added replaying of REDO_RENAME_TABLE
* UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END
* Recovery from the last checkpoint record now possible
* In new_table() we skip the table if the id->name mapping is older than
create_rename_lsn (mapping dates from lsn_of_file_id).
* in get_MARIA_HA_from_REDO_record() we skip the record
if the id->name mapping is newer than the record (can happen if processing
a record which is before the checkpoint record).
* parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
* equivalent of ma_test1's --test-undo added (named -u here).
* -t=1 now stops right after creating the table, so that
we can test undoing of INSERTs with duplicate keys (which tests the
CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
Result of testing undoing of INSERTs with duplicate keys; there are
some differences in maria_chk -dvv but they are normal (removing
records does not shrink data/index file, does not put back the
"analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
Test undoing of INSERTs with duplicate keys, using ma_test2;
when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
CLR_END; we abort after that, and test that CLR_END causes recovery
to jump over UNDO_INSERT.
storage/maria/ma_write.c:
comment
storage/maria/maria_chk.c:
comment
storage/maria/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list
of unique shares during Checkpoint.
* MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID
for this share; needed to know to which LSN domain the mappings
found in the Checkpoint record apply (new mappings should not apply
to old REDOs).
storage/maria/trnman.c:
* small changes to how trnman_collect_transactions() fills its buffer;
it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h

mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

WL#3072 Maria Recovery. Making DDLs durable in Maria:
Sync table files after CREATE (of non-temp table), DROP, RENAME,
TRUNCATE, sync directories and symlinks (for the 3 first commands).
Comments for future log records.
In ma_rename(), if rename of index works and then rename of data fails,
try to undo the rename of the index to leave a consistent state.
mysys/my_symlink.c:
sync directory after creation of a symbolic link in it, if asked
mysys/my_sync.c:
comment. Fix for when the file's name has no directory in it.
storage/maria/ma_create.c:
sync files and links and dirs when creating a non-temporary table.
Optimizations of the above to reduce syncs in the common cases:
* if index file and data file have the exact same paths (regular
and link), sync the directories (of regular and link) only once
after creating the last file (the data file).
* don't sync the data file if we didn't write to it (always true
in our builds).
storage/maria/ma_delete_all.c:
sync files after truncating a table
storage/maria/ma_delete_table.c:
sync files and symbolic links and dirs after dropping a table
storage/maria/ma_extra.c:
a function which wraps the sync of the index file and the sync of the
data file.
storage/maria/ma_locking.c:
using a wrapper function
storage/maria/ma_rename.c:
sync files and symbolic links and dirs after renaming a table.
If rename of index works and then rename of data fails, try to undo
the rename of the index to leave a consistent state. That is just a
try, it may fail...
storage/maria/ma_test3.c:
warning to not pay attention to this test.
storage/maria/maria_def.h:
declaration for the function added to ma_extra.c

Completion of merge of mysql-5.1 into mysql-maria.
Manually imported changes done to MyISAM (include/myisam.h,

mysql-test/t/ps_2myisam.test) the last
months into Maria (tedious, should do it more frequently in the
future), including those not done at the previous 5.1->Maria merge
(please in the future don't forget to apply MyISAM changes to Maria
when you merge 5.1 into Maria).
Note: I didn't try to import anything which could be MyISAM-related
in other tests of mysql-test (I didn't want to dig in all csets),
but as QA is working to make most tests re-usable for other engines
(Falcon), it is likely that we'll benefit from this and just have
to set engine=Maria somewhere to run those tests on Maria.
func_group and partition tests fail but they already do in main 5.1
on my machine. No Valgrind error in t/*maria*.test.

Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
UNDO of rows now puts back all part of the row on their original pages and positions.
Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
Added check_directory() for checking that directroy entries are correct.
Added checking of row checksums when reading rows (with EXTRA_DEBUG)
Added make_space_for_directory() and extend_directory() for doing expansion of directory

Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
Fixed som bugs in directory handling
Fixed bug where we wrote wrong lsn to blob pages
Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
Ensure we call _ma_bitmap_flushable() also in case of errors
When doing an update, first delete old entries, then search in bitmap for where to put new information
Info->s -> share
Rowid -> rowid
More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER

Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)

Completion of merge of mysql-5.1 into mysql-maria.
Manually imported changes done to MyISAM (include/myisam.h,
storage/myisam/*, sql/ha_myisam.*, mysql-test/t/myisam.test,
mysql-test/t/ps_2myisam.test) the last
months into Maria (tedious, should do it more frequently in the
future), including those not done at the previous 5.1->Maria merge
(please in the future don't forget to apply MyISAM changes to Maria
when you merge 5.1 into Maria).
Note: I didn't try to import anything which could be MyISAM-related
in other tests of mysql-test (I didn't want to dig in all csets),
but as QA is working to make most tests re-usable for other engines
(Falcon), it is likely that we'll benefit from this and just have
to set engine=Maria somewhere to run those tests on Maria.
func_group and partition tests fail but they already do in main 5.1
on my machine. No Valgrind error in t/*maria*.test.
Monty: please see the commit comment of maria.result and check.
BitKeeper/deleted/.del-ha_maria.m4:
Delete: config/ac-macros/ha_maria.m4
configure.in:
fix for the new way of enabling engines
include/maria.h:
importing changes done to MyISAM the last months into Maria
include/my_handler.h:
importing changes done to MyISAM the last months into Maria
include/myisam.h:
importing changes done to MyISAM the last months into Maria
mysql-test/r/maria.result:
identical to myisam.result, except the engine name in some places
AND in the line testing key_block_size=1000000000000000000:
Maria gives a key block size of 8192 while MyISAM gives 4096;
is it explainable by the difference between MARIA_KEY_BLOCK_LENGTH
and the same constant in MyISAM? Monty?
mysql-test/r/ps_maria.result:
identical to ps_2myisam.result (except the engine name in some places)
mysql-test/t/maria.test:
instead of engine=maria everywhere, I use @@storage_engine (reduces
the diff with myisam.test).

Completion of merge of mysql-5.1 into mysql-maria.
Manually imported changes done to MyISAM (include/myisam.h,
storage/myisam/*, sql/ha_myisam.*, mysql-test/t/myisam.test,
mysql-test/t/ps_2myisam.test) the last
months into Maria (tedious, should do it more frequently in the
future), including those not done at the previous 5.1->Maria merge
(please in the future don't forget to apply MyISAM changes to Maria
when you merge 5.1 into Maria).
Note: I didn't try to import anything which could be MyISAM-related
in other tests of mysql-test (I didn't want to dig in all csets),
but as QA is working to make most tests re-usable for other engines
(Falcon), it is likely that we'll benefit from this and just have
to set engine=Maria somewhere to run those tests on Maria.
func_group and partition tests fail but they already do in main 5.1
on my machine. No Valgrind error in t/*maria*.test.

Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).
storage/maria/ha_maria.cc:
in ha_maria::backup, need to flush the data file before copying it,
otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
when allocating data at the end of the bitmap, best_data is at "end",
should not be left to 0 (bug 2)
storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.

sql/handler.cc:
Don't call get_dup_key() if there is no table object. This can happen if the handler generates a duplicate key error on commit
sql/handler.h:
Added new argument to end_bulk_insert() to signal if the bulk insert should ignored (ie, the table will be deleted)

sql/protocol.cc:
Added DBUG
sql/sql_class.cc:

Fixed wrong call to strmake
sql/sql_insert.cc:
Don't call bulk insert in case of inserting only one row (speed optimization as starting/stopping bulk insert involves a lot of if's)
Added new argument to ha_end_bulk_insert()
sql/sql_load.cc:
Added new argument to ha_end_bulk_insert()
sql/sql_parse.cc:
Style fixes
Avoid goto in common senario
sql/sql_select.cc:
When running with purify/valgrind avoid copying structures over themself. This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
sql/sql_select.h:
Avoid copying structures over themself. This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
sql/sql_table.cc:
Call HA_EXTRA_PREPARE_FOR_DROP if table created by ALTER TABLE is going to be dropped
Added new argument to ha_end_bulk_insert()

Added new argument to end_bulk_insert()
storage/archive/ha_archive.h:
Added new argument to end_bulk_insert()
storage/federated/ha_federated.cc:
Added new argument to end_bulk_insert()
storage/federated/ha_federated.h:
Added new argument to end_bulk_insert()
storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum
Keep share->state.state.data_file_length up to date (not info->state->data_file_length)
Moved _ma_block_xxxx_status() and maria_versioning() functions to ma_state.c
storage/maria/ma_check.c:
Update and use share->state.state instead of info->state
info->s to share
Update info->state at end of repair
Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
storage/maria/ma_info.c:
Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG
storage/maria/ma_page.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- Modify share->state.state.key_file_length under share->intern_lock

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
info->s -> share

Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- Update state information on close and when reenabling logging

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_rnext.c:
Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_rnext_same.c:
Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_rsame.c:
Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_sort.c:
Use share->state.state instead of info->state
Fixed indentation
storage/maria/ma_static.c:
Added maria_stored_state

Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
- Remove optimization for index file update as it doesn't work for transactional tables
storage/maria/ma_write.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/maria_def.h:
Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions
- Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.
- Added virtual function lock_restore_status
Changes to MARIA_HA:
- save_state -> state_save
- Added state_start to store state at start of transaction

Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).
storage/maria/ha_maria.cc:
in ha_maria::backup, need to flush the data file before copying it,
otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
when allocating data at the end of the bitmap, best_data is at "end",
should not be left to 0 (bug 2)
storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case

WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:

storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed

storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records

- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)

error= 1;
|
Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).
storage/maria/ha_maria.cc:
in ha_maria::backup, need to flush the data file before copying it,
otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
when allocating data at the end of the bitmap, best_data is at "end",
should not be left to 0 (bug 2)
storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.

sql/sql_select.cc:
When running with purify/valgrind avoid copying structures over themself. This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
sql/sql_select.h:
Avoid copying structures over themself. This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings

storage/federated/ha_federated.h:
Added new argument to end_bulk_insert()
storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum
Keep share->state.state.data_file_length up to date (not info->state->data_file_length)

Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
storage/maria/ma_info.c:
Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG
storage/maria/ma_page.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_rsame.c:
Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
storage/maria/ma_sort.c:
Use share->state.state instead of info->state
Fixed indentation
storage/maria/ma_static.c:
Added maria_stored_state

storage/maria/ma_write.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/maria_def.h:
Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions
- Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.
- Added virtual function lock_restore_status
Changes to MARIA_HA:
- save_state -> state_save
- Added state_start to store state at start of transaction

Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).
storage/maria/ha_maria.cc:
in ha_maria::backup, need to flush the data file before copying it,
otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
when allocating data at the end of the bitmap, best_data is at "end",
should not be left to 0 (bug 2)
storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.

storage/federated/ha_federated.cc:
Added new argument to end_bulk_insert()
storage/federated/ha_federated.h:
Added new argument to end_bulk_insert()
storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum
Keep share->state.state.data_file_length up to date (not info->state->data_file_length)
Moved _ma_block_xxxx_status() and maria_versioning() functions to ma_state.c
storage/maria/ma_check.c:
Update and use share->state.state instead of info->state
info->s to share
Update info->state at end of repair
Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:

Versioning of count(*) and checksum:
- Use share->state.state instead of info->state

storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG

Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty

storage/maria/ha_maria.cc:

otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:

storage/maria/ma_check.c:
_ma_scan_block_record() is used in QUICK repair. It relies on
data_file_length. RESTORE TABLE mixes the MAI of an empty table
(so, data_file_length==0) with an non-empty MAD, and does a
QUICK repair; that got fooled (thought it had hit EOF immediately,
so found no records) (bug 1)
storage/maria/ma_create.c:
At the end of maria_create() we have, in the index file,
data_file_length==0, while the data file has a bitmap page (8192).
This inconsistency makes CHECK TABLE rightly complain.
Fixed by not creating a first bitmap page during maria_create()
(also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
A function to flush the data and index files before one can
use OS syscalls (reads, writes) on those files. For example,
ha_maria::backup() does a my_copy() of the data file and so
all cached pieces of this file must be sent to the OS (bug 1)
This function will have to be used elsewhere in Maria, several places
have not been updated when we added pagecache-ing of the data file
(they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:

storage/maria/maria_def.h:
new function. Needs to be visible from ha_maria::backup.
