- serializing calls to flush_pagecache_blocks_int() on the same file
to avoid known concurrency bugs
- having that, we can now enable the background thread, as the
flushes it does are now supposedly safe in concurrent situations.
- new type of flush FLUSH_KEEP_LAZY: when the background checkpoint
thread is flushing a packet of dirty pages between two checkpoints,
it uses this flush type, indeed if a file is already being flushed
by another thread it's smarter to move on to the next file than wait.
- maria_checkpoint_frequency renamed to maria_checkpoint_interval.


include/my_sys.h:
  new type of flushing for the page cache: FLUSH_KEEP_LAZY
mysql-test/r/maria.result:
  result update
mysys/mf_keycache.c:
  indentation. No FLUSH_KEEP_LAZY support in key cache.
storage/maria/ha_maria.cc:
  maria_checkpoint_frequency was somehow a hidden part of the
  Checkpoint API and that was not good. Now we have checkpoint_interval,
  local to ha_maria.cc, which serves as container for the user-visible
  maria_checkpoint_interval global variable; setting it calls
  update_checkpoint_interval which passes the new value to
  ma_checkpoint_init(). There is no hiding anymore.
  By default, enable background thread which does checkpoints
  every 30 seconds, and dirty page flush in between. That thread takes
  a checkpoint when it ends, so no need for maria_hton_panic to take one.
  The | is | and not ||, because maria_panic() must always be called.
  frequency->interval.
storage/maria/ma_checkpoint.c:
  Use FLUSH_KEEP_LAZY for background thread when it flushes packets of
  dirty pages between two checkpoints: it is smarter to move on to
  the next file than wait for it to have been completely flushed, which
  may take long.
  Comments about flush concurrency bugs moved from ma_pagecache.c.
  Removing out-of-date comment.
  frequency->interval.
  create_background_thread -> (interval>0).
  In ma_checkpoint_background(), some variables need to be preserved
  between iterations.
storage/maria/ma_checkpoint.h:
  new prototype
storage/maria/ma_pagecache.c:
  - concurrent calls of flush_pagecache_blocks_int() on the same file
  cause bugs (see @note in that function); we fix them by serializing
  in this situation. For that we use a global hash of (file, wqueue).
  When flush_pagecache_blocks_int() starts it looks into the hash,
  using the file as key. If not found, it inserts (file,wqueue) into the
  hash, flushes the file, and finally removes itself from the hash and
  wakes up any waiter in the queue. If found, it adds itself to the
  wqueue and waits.
  - As a by-product, we can remove changed_blocks_is_incomplete
  and replace it by scanning the hash, replace the sleep() by a queue wait.
  - new type of flush FLUSH_KEEP_LAZY: when flushing a file, if it's
  already being flushed by another thread (even partially), return
  immediately.
storage/maria/ma_pagecache.h:
  In pagecache, a hash of files currently being flushed (i.e. there
  is a call to flush_pagecache_blocks_int() for them).

storage/maria/ma_recovery.c:
  Auto merged

Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.


mysql-test/r/maria.result:
  result update
storage/maria/ha_maria.cc:
  blank after function comment
storage/maria/ma_checkpoint.c:
  Using an enum instead of 0/1/2 (applying Sanja's review comments).
  The comment about "this is an horizon" can be removed as Sanja
  created translog_next_LSN() which parse_checkpoint_record() uses.
  Variables in ma_checkpoint_background() cannot be declared in the
  for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
  adding to flush_pagecache_blocks() optional arguments 'filter'
  (pointer to function) and 'filter_arg'; if filter!=NULL this function
  will be called for each block of the file and will reply if this
  block and following ones should be flushed or not (3 possible
  replies).
  Fixing a bug when flush_cached_blocks() skips a pinned page: it has
  to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
  flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
  arguments. "filter", if it is not NULL, may return one value
  among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
  open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
  Optional checkpoints (-H#) at various stages (stages similar
  to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
  Optional checkpoints (-H#) at various stages (stages similar
  to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
  Result update: the results of the additional test run with -H#
  (checkpoints) are added here. They are exactly identical to without
  checkpoints except that the index's Root (printed by maria_chk)
  is more correct when using checkpoints. This is because checkpoint
  flushed the state, so it happens to be correct, while no-checkpoint
  does not flush the state, and recovery does not recover indexes
  so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
  We duplicate the loop of tests to add an additional run with
  checkpoints at various stages, to see if maria_read_log
  uses them fine.

storage/maria/ma_pagecache.c:
  work around infamous "PAGECACHE_PLAIN_PAGE used for transactional
  tables in specialm case"; REDO phase disables logging and this causes
  pages to be PAGECACHE_PLAIN_PAGE, thus ignored wrongly by the
  checkpoint taken at the end of the REDO phase.
storage/maria/ma_recovery.c:
  - a #ifdef which broke maria_read_log in non-debug builds (no output!)
  - support for maria_read_log --check
  - detect record corruption before opening the table
  - updating is_of_horizon requires writing the state
  - fix for wrong parsing of checkpoint record by recovery
storage/maria/ma_recovery.h:
  support for maria_read_log --check
storage/maria/maria_read_log.c:
  Option --check: --only-display only looks at the header;

  be fully read (this is to find bugs).

* Preparation for having a background checkpoint thread:
frequency of checkpoint taken by that thread is now configurable
by the user: global variable maria_checkpoint_frequency, in seconds,
default 30 (checkpoint every 30th second); 0 means no checkpoints
(and thus no background thread, thus no background flushing, that
will probably only be used for testing).
* Don't take checkpoints in Recovery if it didn't do anything
significant; thus no checkpoint after a clean shutdown/restart. The
only checkpoint which is never skipped is the one at shutdown.
* fix for a test failure (after-merge fix)


include/maria.h:
  new variable
mysql-test/suite/rpl/r/rpl_row_flsh_tbls.result:
  result update
mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test:
  position update (=after merge fix, as this position was already changed
  into 5.1 and not merged here, causing test to fail)
storage/maria/ha_maria.cc:
  Checkpoint's frequency is now configurable by the user:
  global variable maria_checkpoint_frequency. Changing it on the fly
  requires us to shutdown/restart the background checkpoint thread,
  as the loop done in that thread assumes a constant checkpoint
  interval. Default value is 30: a checkpoint every 30 seconds (yes, I
  know, physicists will remind that it should be named "period" then).
  ha_maria now asks for a background checkpoint thread when it starts,
  but this is still overruled (disabled) in ma_checkpoint_init().
storage/maria/ma_checkpoint.c:
  Checkpoint's frequency is now configurable by the user: background thread
  takes a checkpoint every maria_checkpoint_interval-th second.
  If that variable is 0, no checkpoints are taken.
  Note, I will enable the background thread only in a later changeset.
storage/maria/ma_recovery.c:
  Don't take checkpoints at the end of the REDO phase and at the end of
  Recovery if Recovery didn't make anything significant (didn't open
  any tables, didn't rollback any transactions).
  With this, after a clean shutdown, Recovery shouldn't take any
  checkpoint, which makes starting faster (we save a few fsync()s of
  the log and control file).

moved debugging defines.

content before it was actually written, now
we abvance pointer in new buffer and unlock
it while waiting for filling old buffer)
