d72c22dee4 WL#3072 - Maria recovery.
* fix for bitmap vs checkpoint bug which could lead to corrupted
tables in case of crashes at certain moments: a bitmap could be flushed
to disk even though it was inconsistent with the log (it could be
flushed before REDO-UNDO are written to the log). One bug remains, need
code from others. Tests added. Fix is to pin unflushable bitmap pages,
and let checkpoint wait for them to be flushable.
* fix for long_trid!=0 assertion failure at Recovery.
* less useless wakeups in the background flush|checkpoint thread.
* store global_trid_generator in checkpoint record.


mysql-test/r/maria-recovery.result:
  result update
mysql-test/t/maria-recovery.test:
  make it easier to locate subtests
storage/maria/ma_bitmap.c:
  When we send a bitmap to the pagecache, if this bitmap is not in a
  flushable state we keep it pinned and add it to a list, it will be
  unpinned when the bitmap is flushable again.
  A new function _ma_bitmap_flush_all() used by checkpoint.
  A new function _ma_bitmap_flushable() used by block format to signal
  when it starts modifying a bitmap and when it is done with it.
storage/maria/ma_blockrec.c:
  When starting a row operation (insert/update/delete), mark that
  the bitmap is not flushable (because for example INSERT is going
  to over-allocate in the bitmap to prevent other threads from using
  our data pages). If a checkpoint comes at this moment it will wait
  for the bitmap to be flushable before flushing it.
  When the operation ends, bitmap becomes flushable again; that
  transition is done under the bitmap's mutex (needed for correct
  synchro with a concurrent checkpoint); but for INSERT/UPDATE this
  happens inside _ma_bitmap_release_unused() at a place where it already
  has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO
  of INSERT. In case of errors after setting the bitmap unflushable,
  we must always set it back to flushable or checkpoint would block.
  Debug possibilities to force a sleep while the bitmap is over-allocated.
  In case of error in get_head_or_tail() in allocate_and_write_block_record(),
  we still need to unpin all pages.
  Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong
  data_file_length.
storage/maria/ma_blockrec.h:
  new bitmap calls.
storage/maria/ma_checkpoint.c:
  filter_flush_indirect not needed anymore (flushing bitmap
  pages happens in _ma_bitmap_flush_all() now). So
  st_filter_param::is_data_file|pages_covered_by_bitmap not needed.
  Other filter_flush* don't need to flush bitmap anymore.
  Add debug possibility to flush all bitmap pages outside of a checkpoint,
  to simulate pagecache LRU eviction.
  When the background flush/checkpoint thread notices it has nothing
  to flush, it now sleeps directly until the next potential checkpoint
  moment instead of waking up every second.
  When in checkpoint we decide to not store a table in the checkpoint record
  (because it has logged no writes for example), we can also skip flushing
  this table.

  comment for bug to fix. And we don't take checkpoints at end of REDO
  phase yet so can trust block->type.
storage/maria/ma_recovery.c:
  Comments. Now-unneeded code for incomplete REDO-UNDO groups removed.
  When we forget about an old transaction we must really forget
  about it with bzero() (fixes the "long_trid!=0 assertion" recovery
  bug). When we delete a row with maria_delete() we turn on
  STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END
  for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both
  cases a row was deleted). Pick up max_long_trid from the checkpoint record.
storage/maria/maria_chk.c:
  comment
storage/maria/maria_def.h:
  MARIA_FILE_BITMAP gets new members: 'flushable', 'bitmap_cond' and
  'pinned_pages'.
storage/maria/trnman.c:
  I used to think that recovery only needs to know the maximum TrID
  of the lists of active and committed transactions. But no, sometimes
  both lists can even be empty and their TrID should not be reused.
  So Checkpoint now saves global_trid_generator in the checkpoint record.
storage/maria/trnman_public.h:
  macros to read/store a TrID
mysql-test/r/maria-recovery-bitmap.result:
  result is ok. Without the code fix, we would get a corruption message
  about the bitmap page in CHECK TABLE EXTENDED.

cec8ac3e07 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

69d7db7758 WL#3072 - Maria Recovery
At the end of recovery, we initialize the transaction manager's
trid generator with the maximum trid seen during the REDO phase.
This ensures that trids always grow (needed for versioning),
even after a crash.
This patch is only preparation, as ma_recover() is not called
from ha_maria yet.


storage/maria/ha_maria.cc:
  trnman_init() needs argument now (soon trnman_init() will rather
  be done via ma_recover() and thus it will not be 0)
storage/maria/ma_recovery.c:
  During the REDO phase, remember the max long trid of transactions
  which we have seen (both in the checkpoint record and the
  LOGREC_LONG_TRANSACTION_ID records)
storage/maria/ma_test1.c:
  trnman_init() needs argument now
storage/maria/ma_test2.c:
  trnman_init() needs argument now
storage/maria/trnman.c:

  value the generator of trids starts from.

e27890cab0 WL#3072 Maria recovery
* create page cache before initializing engine and not after, because
Maria's recovery needs a page cache
* make the creation of a bitmap page more crash-resistent
* bugfix (see ma_blockrec.c)
* back to old way: create an 8k bitmap page when creating table
* preparations for the UNDO phase: recreate TRNs
* preparations for Checkpoint: list of dirty pages, testing
of rec_lsn to know if page should be skipped during Recovery
(unused in this patch as no Checkpoint module pushed yet)
* maria_chk tags repaired table with a special LSN
* reworking all around in ma_recovery.c (less duplication)


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
  test if this is recovery.
storage/maria/ma_control_file.h:
  new prototype
storage/maria/ma_create.c:
  Back to how it was before: maria_create() creates an 8k bitmap page.
  Thus (bugfix) data_file_length needs to reflect this instead of being 0.
storage/maria/ma_loghandler.c:
  as ma_test1 and ma_test2 now use real transactions and not
  dummy_transaction_object, REDO for INSERT/UPDATE/DELETE are always
  about real transactions, can assert this.
  A function for Recovery to assign a short id to a table.
storage/maria/ma_loghandler.h:
  new function
storage/maria/ma_loghandler_lsn.h:
  maria_chk tags repaired tables with this LSN
storage/maria/ma_open.c:
  * enforce that DMLs on transactional tables use real transactions
  and not dummy_transaction_object.
  * test if table was repaired with maria_chk (which has to been
  seen as an import of an external table into the server), test
  validity of create_rename_lsn (header corruption detection)
  * comments.
storage/maria/ma_recovery.c:
  * preparations for the UNDO phase: recreate TRNs
  * preparations for Checkpoint: list of dirty pages, testing
  of rec_lsn to know if page should be skipped during Recovery
  (unused in this patch as no Checkpoint module pushed yet)
  * reworking all around (less duplication)
storage/maria/ma_recovery.h:
  a parameter to say if the UNDO phase should be skipped
storage/maria/maria_chk.c:
  tag repaired tables with a special LSN
storage/maria/maria_read_log.c:
  * update to new prototype
  * no UNDO phase in maria_read_log for now
storage/maria/trnman.c:
  * a function for Recovery to create a transaction (TRN), needed
  in the UNDO phase
  * a function for Recovery to grab an existing transaction, needed
  in the UNDO phase (rollback all existing transactions)

662002fc8f post-merge fixes, and fixes for some of the 16 compiler warnings
found in pushbuild on sapsrv1. Some not fixed as not repeatable
on my machine (32/64 bit issue?).
Fixes for some test failures:
- "maria-connect" now passes;
- "maria": after fixing the obvious reasons for failures, the test
went further and hit a more complex issues: difference in the output
of EXPLAIN output; not fixed;
- "ps_maria" still crashes in assertion
mysqld: ha_maria.cc:1627: virtual int ha_maria::index_read(uchar*, const uchar*, uint, ha_rkey_function): Ass
ertion `inited == INDEX' failed, as already observable in pushbuild.
All this might just be due to an incomplete merge of MyISAM changes
into Maria when 5.1 was last merged to mysql-maria.

1a96259191 - 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/ma_blockrec.c:

  - 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:

  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:

storage/maria/ma_init.c:
  when maria_end() is called, engine is not multithreaded

  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_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:
  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 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.

704b39a158 - moving pagecache.h from include/ to storage/maria as it is Maria-
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

  trn->rec_lsn and trn->undo_lsn are now set via hooks inside the log
  record's writing; this allows to also set trn->first_undo_lsn
  needed to compute the log's low-water mark.
  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.

8410950316 fix for 2 memory leaks in ps_maria.test (just need to destroy objects
allocated at startup).


storage/maria/ma_init.c:
  destroy transaction manager and log's pagecache when Maria shuts down
storage/maria/trnman.c:
  short_trid_to_active_trn!=NULL now serves to detect if
  trnman has initialized some objects and so if trnman_destroy()
  has objects to destroy. In other words, short_trid_to_active_trn
  serves as "trnman_inited" variable.
  trnman_destroy() is always called by maria_end(), but trnman_init() is
  not always called (for example in ma_test1), that's why
  trnman_destroy() cannot blindly destroy.
