misc fixes of execution of UNDOs in the UNDO phase:
- into the CLR_END, store the LSN of the _previous_ UNDO (we debated
what was best, so far we're going with "previous"; later we can change
to "current" if needed), and store the type of record which is being
undone (needed to know how to update state.records when we see the
CLR_END during the REDO phase).
- declaring all UNDOs and CLR_END as "compressed"
- when executing an UNDO in the UNDO phase, state.records is updated
as a hook when writing CLR_END (needed for "recovery of the state"),
and so is trn->undo_lsn (needed for when we have checkpoints).
- bugfix (execution of UNDO_ROW_DELETE didn't store the correct checksum
into the re-inserted row, maria_chk -r thus threw the row away).
- modifications of ma_test1: where to stop is now driven by --testflag;
--test-undo just tells how to stop (flush data, flush log, nothing).
- ma_test_recovery: testing of the UNDO phase, more testing of the
REDO phase, identification of a bug.
storage/maria/ma_blockrec.c:
- bugfix: execution of UNDO_ROW_DELETE didn't store the correct
checksum into the row (leading to "maria_chk -r" eliminating the
re-inserted row, net effect was that rollback appeared to have
rolled back no deletion). Reason was that write_block_record() used
info->cur_row.checksum, while "row" can be != &info->cur_row
(case of UNDO_ROW_DELETE). After fixing this, problems with
_ma_update_block_record() appeared; indeed checksum was computed
by allocate_and_write_block_record() while _ma_update_block_record()
directly calls write_block_record(). Solution is to compute checksum
in write_block_record() instead.
- when executing an UNDO, we now pass the LSN of the _previous_ UNDO
to block_format functions. This LSN can be 0 (if the being-executed UNDO
was the transaction's first UNDO), so "undo_lsn==0" cannot work
anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR
instead (this is an impossible LSN).
- store into CLR_END the type of log record which was undone
(INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has
to update state.records if it sees this CLR_END in the REDO phase.
- when writing the CLR_END in _ma_apply_undo_row_insert(),
the place to store file's id is log_data+LSN_STORE_SIZE.
- in _ma_apply_undo_row_insert(), the records-- is moved
to a hook when writing the CLR_END (this way it is under log's mutex
which is needed for "recovery of the state")
storage/maria/ma_loghandler.c:
- all UNDOs, and CLR_END, start with the LSN of another UNDO; so
we can declare them "compressed".
- write_hook_for_clr_end() to set trn->undo_lsn (to the previous
UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's
lock), and also update, if appropriate, state.records.
- reset share->id to 0 when deassigning; not useful for now but
sounds logical.
storage/maria/ma_recovery.c:
- if no table is found for a REDO, it's not an error; for an UNDO, it is
- in the REDO phase, when we see a CLR_END we must update trn->undo_lsn
and sometimes state.records.
- in the UNDO phase, when we execute an UNDO_ROW_INSERT:
* update trn->undo_lsn only after executing the record
* store the _previous_ undo_lsn into the CLR_END
- at the end of the REDO phase, when we recreate TRN objects, they
have already their long id in the log (either via a
LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write
a new, useless LOGREC_LONG_TRANSACTION_ID for them.
storage/maria/ma_test1.c:
* where to stop execution is now driven by --testflag and not --test-undo
(ma_test2 already has --testflag for the same purpose). This allows
us to do a clean stop (with commit) at any point.
* --test-undo=# tells how to abort (flush all pages (which implies
flushing log) or only log or nothing); all such "ways of crashing"
are tested in ma_test_recovery
storage/maria/ma_test_recovery:
* Testing execution of UNDOs, with and without BLOBs.
* Testing idempotency of REDOs.
* See @todo for a probable bug with BLOBs.
* maria_chk -rq instead of -r, as with -q it nicely stops on any
problem in the data file (like the checksum bug see comment of
ma_blockrec.c).
* Testing if log was written by UNDO phase (often expected),
not written by REDO phase (always expected).
* Less output on the screen, compares with expected output in the end.
* some shell thingies like "set --" and $# are courtesy of
Danny and Pekka.
storage/maria/maria_read_log.c:
when only displaying the records, don't do an UNDO phase
storage/maria/ma_test_recovery.expected:
This is the expected output of a great part of ma_test_recovery.
ma_test_recovery compares its output to the expected output
and tells if different.
If we look at this file it mentions differences in checksum
(normal, it's not recovered yet) and in records count
(getting a correct records' count when recovery starts on an
already existing table, like when testing rollback,
is coded but not yet pushed).
Small fixes made.
storage/maria/ma_loghandler.c:
Check of transaction log descriptor table consistance added.\
Incorrect record description fixed.
Compiler warning fixed.

Added UNDO handling of insert during recovery
To do this, I also had to add write locking of tail pages during undo phase (As we need to access the same page twice if extents are split over two pages)
Another way to handle the undo of insert would be to store the extent information as part of the UNDO_INSERT block.
storage/maria/ma_blockrec.h:
Added new prototype
storage/maria/ma_loghandler.c:
Changed type of CLR_END (to avoid crash in log handler)
Removed not used variable
storage/maria/ma_loghandler.h:
Added TRN argument to record_execute_in_undo_phase()
storage/maria/ma_pagecache.c:
Hack for undo phase of recovery. During REDO we work with PLAIN pages, but UNDO works with LSN pages, which caused an abort when trying to access a cached page.
storage/maria/ma_recovery.c:
Added execution of UNDO_ROW_INSERT
storage/maria/ma_test1.c:
Added option --test-undo for testing recovery with undo

mysys/my_realloc.c:
noted an issue in my_realloc()
sql/mysqld.cc:
page cache needs to be created before engines are initialized,
because Maria's initialization may do a recovery which needs
the page cache.
storage/maria/ha_maria.cc:
update to new prototype
storage/maria/ma_bitmap.c:
when creating the first bitmap page we used chsize to 8192 bytes then
pwrite (overwrite) the last 2 bytes (8191-8192). If crash between
the two operations, this leaves a bitmap page full without its end
marker. A later recovery may try to read this page and find it
exists and misses a marker and conclude it's corrupted and fail.
Changing the chsize to only 8190 bytes: recovery will then find
the page is too short and recreate it entirely.
storage/maria/ma_blockrec.c:
Fix for a bug: when executing a REDO, if the data page is created,
data_file_length was increased before _ma_bitmap_set():
_ma_bitmap_set() called _ma_read_bitmap_page() which, due to the
increased data_file_length, expected to find a bitmap page on disk
with a correct end marker; if the bitmap page didn't exist already
in fact, this failed. Fixed by increasing data_file_length only after
_ma_read_bitmap_page() has created the new bitmap page correctly.
This bug could happen every time a REDO is about creating a new
bitmap page.
storage/maria/ma_check.c:
empty data file has a bitmap page
storage/maria/ma_control_file.c:
useless parameter to ma_control_file_create_or_open(), just

storage/maria/ma_control_file.h:

Thus (bugfix) data_file_length needs to reflect this instead of being 0.
storage/maria/ma_loghandler.c:

Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs
Note: The .MAD file is not binary identical after applying redo compare to a an original file.

Preparation: for the two-checkpoint rule we will flush all pages
which have block->rec_lsn <= last_checkpoint_lsn. Pages with
rec_lsn not yet set (i.e. ==0) were dirtied very recently and so should
not be flushed (otherwise it's not efficient: we should try to let
a page be modified several times in memory before we flush it to disk).
To make this easy, "block->rec_lsn not yet set" is now expressed
with block->rec_lsn==LSN_MAX, not block->rec_lsn==0 anymore.
It is easier this way because LSN_MAX>last_checkpoint_lsn whereas
0<=last_checkpoint_lsn.

preparation to enable recoverability of the table's state, more exactly
info->state->checksum. This will require that info->state->checksum
be updated in a inwrite_hook when writing an UNDO record, thus
info->cur_row.checksum needs to be accessible to inwrite_hook, so we
make translog_write_record() accept a MARIA_HA* (info) instead of
MARIA_SHARE* (info->s); with this, we will be able to access
info->cur_row.checksum. Old code which needed the MARIA_SHARE
can derive it from MARIA_HA. Fix for typos and compiler warnings.

the other way around). MARIA_HA will be needed to allow recoverability
of the table's state.
Fixing wrong DBUG_PRINT ('i' is not the id).
When writing the LOGREC_FILE_ID, we don't have a MARIA_HA around,
so we cannot ask translog_write_record() to store the id for us;
we thus store the file's id by ourselves. Alternative would have been
to pass MARIA_HA to translog_assign_id_to_share() but I didn't like it.
storage/maria/ma_loghandler.h:

storage/maria/ma_loghandler.c:
Functions reading record's header now don't use 0 to indicate error,
as some valid records have a 0-length header (like REDO_DROP_TABLE).
Instead, negative values are used for EOF and error.
storage/maria/ma_loghandler.h:
functions to read record's header now return an int

Bitmap-related part of _ma_initialize_datafile() moves in bitmap module.
Now putting the "bm" signature when creating the first bitmap page
(it used to happen only at next open, but that
caused an annoying difference when testing Recovery if the original
run didn't open the table, and it looks more
logical like this: it goes to disk only with its signature correct);
see the "QQ" comment towards the _ma_initialize_data_file() call
in ma_create.c for more).
When reading a bitmap page, verify its signature (happens when normally
using the table or when CHECKing it; not when REPAIRing it).
storage/maria/ma_blockrec.c:
* no need to sync the data file if table is not transactional
* Comments, code cleanup (log-related data moved to log-related code
block, int5store->page_store).
* Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we
do for other records (though this record will soon be replaced
with a CLR).
* If "page" is 1 it means the page which extends from byte
page*block_size+1 to (page+1)*block_size (byte number 1 being
the first byte of the file). The last byte of the file is
data_file_length (same convention).
A new page needs to be created if the last byte of the page is
beyond the last byte of the file, i.e.
(page+1)*block_size+1 > data_file_length, so we correct the test
(bug found when testing log applying for ma_test1 -M -T --skip-update).

storage/maria/ma_blockrec.h:
new functions. maria_bitmap_marker does not need to be exported.
storage/maria/ma_close.c:
we can always flush the table's state when closing the last instance
of the table. And it is needed for maria_read_log (as it does
not use maria_lock_database()).
storage/maria/ma_control_file.c:
when in Recovery, some assertions should not be used.
storage/maria/ma_control_file.h:
double-inclusion safe
storage/maria/ma_create.c:
during recovery, don't log records. Comments.
Moving the creation of the first bitmap page to ma_bitmap.c
storage/maria/ma_delete_table.c:
during recovery, don't log records. Log the end-zero of the dropped
table's name, so that recovery can use the string in place without
extending it to fit an end zero.
storage/maria/ma_loghandler.c:
* inwrite_rec_hook also needs access to the MARIA_SHARE, like
prewrite_rec_hook. This will be needed to update
share->records_diff (in the upcoming patch "recovery of the state").
* LOG_DESC::record_ends_group changed to an enum.
* LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE
corrected
* Sanja please see the @todo LOG BUG
* avoiding DBUG_RETURN(func()) as it gives confusing debug traces.
storage/maria/ma_loghandler.h:
- log write hooks called while the log's lock is held (inwrite_rec_hook)
now need the MARIA_SHARE, like prewrite_rec_hook already had
- instead of a bool saying if this record's type ends groups or not,
we refine: it may not end a group, it may end a group, or it may
be a group in itself. Imagine that we had a physical write failure
to a table before we log the UNDO, we still end up in
external_lock(F_UNLCK) and then we log a COMMIT: we don't want
to consider this COMMIT as ending the group of REDOs (don't want
to execute those REDOs during Recovery), that's why we say "COMMIT
is a group in itself, it aborts any previous group". This also
gives one more sanity check in maria_read_log.
storage/maria/ma_recovery.c:
New Recovery code, replacing the old pseudocode.
Most of maria_read_log moved here.
Call-able from ha_maria, but not enabled yet.
Compared to the previous version of maria_read_log, some bugs have
been fixed, debugging output can go to stdout or a disk file (for now
it's useful for me, later it can be changed), execution of
REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code
has been factored into functions. We abort an unfinished group
of records if we see a record which is a group in itself (like COMMIT).
No need for maria_panic() after a bug (which caused tables to not
be closed) was fixed; if there is yet another bug I prefer to see it.
When opening a table for Recovery, set data_file_length
and key_file_length to their real physical value (these are the
easiest state members to restore :). Warn us if the last page
was truncated (but Recovery handles it).
MARIA_SHARE::state::state::records is now partly recovered (not
idempotent, but works if recreating tables from scracth).
When applying a REDO to a page, stamp it with the UNDO's LSN
(current_group_end_lsn), not with the REDO's LSN; it makes
the table more identical to the original table (easier to compare
the two tables in the end).
Big thing missing: some types of REDOs are not handled,
and the UNDO phase does not exist (missing functions to execute UNDOs
to actually rollback). So for now tests are only inserting/deleting
a few 100 rows, closing the table and seeing if the log is applied ok;
it works. UPDATE not handled.
storage/maria/ma_recovery.h:
new functions: ma_recover() for recovery from inside ha_maria;
_ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()).
Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore.
storage/maria/ma_rename.c:
don't write log records during recovery
storage/maria/ma_test2.c:
- fail if maria_info() or other subtests find some wrong information
- new option -g to skip updates.
- init the translog before creating the table, so that log applying
can work.
- in "#if 0" you'll see some fixed bugs (will be removed).
storage/maria/ma_test_all.sh:
cleanup files. Test log applying.
storage/maria/maria_read_log.c:
most of the logic moves to ma_recovery.c to be shared between
maria_read_log and recovery-from-inside-mysqld.
See ma_recovery.c for additional changes made to the moved code.
storage/maria/ma_test_recovery:
unit test for Recovery. Tests insert and delete,
REDO_UPDATE not yet coded.
Script is called from ma_test_all. Can run standalone.

* Don't modify share->base.born_transactional; now it is a value carved
in stone at creation time. share->now_transactional is what can be
modified: it starts at born_transactional, can become false during
ALTER TABLE (when we want no logging), and restored later.
* Not resetting create_rename_lsn to 0 during delete_all or repair.
* when we temporarily disable transactionality, we also change
the page type to PAGECACHE_PLAIN_PAGE: it bypasses some work in the
page cache (optimization), and avoids assertions related to LSNs.
* Disable INSERT DELAYED for transactional tables, because
durability could not be guaranteed (insertion may even not happen)
mysys/mf_keycache.c:
comment
storage/maria/ha_maria.cc:
* a transactional table cannot do INSERT DELAYED
* ha_maria::save_transactional not needed anymore, as now instead
we don't modify MARIA_SHARE::MARIA_BASE_INFO::born_transactional
(born_transactional plays the role of save_transactional), and modify
MARIA_SHARE::now_transactional.
* REPAIR_TABLE log record is now logged by maria_repair()
* comment why we rely on born_transactional to know if we should
skipping a transaction.
* putting together two if()s which test for F_UNLCK
storage/maria/ha_maria.h:
ha_maria::save_transactional not needed anymore (moved to the C layer)
storage/maria/ma_blockrec.c:
* For the block record's code (writing/updating/deleting records),
all that counts is now_transactional, not born_transactional.
* As we now set the page type to PAGECACHE_PLAIN_PAGE for tables
which have now_transactional==FALSE, pagecache will not expect
a meaningful LSN for them in pagecache_unlock_by_link(), so
we can pass it LSN_IMPOSSIBLE.
storage/maria/ma_check.c:
* writing LOGREC_REPAIR_TABLE moves from ha_maria::repair()
to maria_repair(), sounds cleaner (less functions to export).
* when opening a table during REPAIR, don't use the realpath-ed name,
as this may fail if the table has symlinked files (maria_open()
would try to find the data and index file in the directory
of unique_file_name, it would fail if data and index files are in
different dirs); use the unresolved name, open_file_name, which is
the argument which was passed to the maria_open() which created 'info'.

storage/maria/ma_create.c:
new name
storage/maria/ma_delete_all.c:
* using now_transactional
* no reason to reset create_rename_lsn during delete_all (a bug);
also no reason to do it during repair: it was put there because
a positive create_rename_lsn caused a call to check_and_set_lsn()
which asserted in DBUG_ASSERT(block->type == PAGECACHE_LSN_PAGE);
first solution was to use LSN_IMPOSSIBLE in _ma_unpin_all_pages() if
not transactional; but then in the case of ALTER TABLE, with
transactionality temporarily disabled, it asserted in
DBUG_ASSERT(LSN_VALID(lsn)) in pagecache_fwrite() (PAGECACHE_LSN_PAGE
page with zero LSN - bad). The additional solution is to use
PAGECACHE_PLAIN_PAGE when we disable transactionality temporarily: this
avoids checks on the LSN, and also bypasses (optimization) the "flush
log up to LSN" call when the pagecache flushes our page (in other
words, no WAL needed).

comment
storage/maria/maria_read_log.c:
program to read and print log records from a Maria transaction log,
and optionally apply them to tables. Very basic, early version.
Should serve as a base for Recovery's code. Designed to be idempotent.
Create a log by running maria.test, then cd to var/master-data
and run "maria_read_log --only-display" to see info about records;
run "maria_read_log --display-and-apply" to also apply the records
to tables (it's more interesting if you first wipe out the
tables in var/master-data/test, to see how they get re-created).
Only a few records are handled by now: LONG_TRANSACTION_ID,
COMMIT, FILE_ID, REDO_CREATE_TABLE; place is ready for
REDO_INSERT_ROW_HEAD where I could use Monty's help (search for
"Monty" in the file). Note: changes to the index pages, index's header
and bitmap pages are not properly logged yet, so don't expect
the program to work with that.
- 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).

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:
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.

specific
- adding TRN::first_undo_lsn, needed to know when a log can be deleted;
this variable must be set under log's mutex and that leads to setting
TRN::rec_lsn, TRN::undo_lsn and TRN::first_undo_lsn in a
inwrite_rec_hook; adding implementation of one hook for REDOs and one
for UNDOs. Thus translog_write_record() always uses TRN and so does
not need a short_id argument, can find it from TRN.
- Monty's patch for the last Valgrind error in the tree.
- Log handler's unit tests fail but Sanja says it's known

The PAGERANGE_STORE_SIZE -> PAGE_STORE_SIZE is Monty's fix to a
Valgrind error.
storage/maria/ma_loghandler.c:
"tcb" renamed to "trn". Log handler now knows what is a transaction,
and finds short_id from trn. trn's rec_lsn, undo_lsn, first_undo_lsn
are now set by some inwrite_rec_hookS (one for REDOs, one for UNDOs).
The HAVE_purify blocks are Monty's fix to a Valgrind error.
