unittest/mysys/Makefile.am:
  add test_file.h in the tarball

make it return an error (except if certain errno), test this error in
callers. Do a single my_sync_dir() in my_rename() if possible.


include/my_global.h:
  better have a symbol name talking about the feature, use it in the
  code of the feature, and define the symbol once depending on the
  platform, rather than have the platform "tested" in the code
  of the feature several times.
include/my_sys.h:
  my_sync_dir() now can return error
mysys/my_create.c:
  my_sync_dir() can now return an error
mysys/my_delete.c:
  my_sync_dir() can now return an error
mysys/my_rename.c:
  my_sync_dir() can now return an error.
  Do a single sync if "from" and "to" are the same directory.
  #ifdef here to not even compile dirname_part() if useless.
mysys/my_sync.c:
  more comments.
  A compilation error if no way to make my_sync() work (I guess
  we don't want to ship a binary which cannot do any sync at all;
  users of strange OSes compile from source and can remove
  the #error).
  my_sync_dir() now returns an error (except for certain errno values
  considered ok; EIO "input/output error" is not ok).
sql/unireg.cc:
  my_sync_dir() now returns an error which must be tested

1) on Mac OS X >=10.3, fcntl() is recommended over fsync (from the
man page: "[With fsync()] the disk drive may also re-order the data
so that later writes may be present while earlier writes are not.
Applications such as databases that require a strict ordering of writes
should use F_FULLFSYNC to ensure their data is written in the order
they expect"). I have seen two other pieces of software changing from
fsync to F_FULLFSYNC on Mac OS X.
2) to make a file creation/deletion/renaming durable on Linux (at least
ext2 as I have tested) (see "man fsync"), a fsync() on the directory
is needed: new functions to do that, and a flag MY_SYNC_DIR to do
it in my_create/my_delete/my_rename.
3) now using this directory syncing when creating he frm if
opt_sync_frm, and for Maria's control file when it is created.


include/my_sys.h:
  new flag to my_create/my_delete/my_rename, which asks to sync the
  directory after the operation is done (currently does nothing except
  on Linux)
libmysql/CMakeLists.txt:
  my_create() now depends on my_sync() so my_sync is needed for libmysql
libmysql/Makefile.shared:
  my_create() now depends on my_sync() so my_sync is needed for libmysql
mysys/my_create.c:
  my_create() can now sync the directory if asked for
mysys/my_delete.c:
  my_delete() can now sync the directory if asked for
mysys/my_open.c:
  it was a bug that my_close() is done on fd but a positive fd would
  still be returned, by my_register_filename().
mysys/my_rename.c:
  my_rename() can now sync the two directories (the one of "from" and
  the one of "to") if asked for.
mysys/my_sync.c:
  On recent Mac OS X, fcntl(F_FULLFSYNC) is recommended over fsync()
  (see "man fsync" on Mac OS X 10.3).
  my_sync_dir(): to sync a directory after a file creation/deletion/
  renaming; can be called directly or via MY_SYNC_DIR in my_create/
  my_delete/my_rename(). No-op except on Linux (see "man fsync" on Linux).
  my_sync_dir_from_file(): same as above, just more practical when the
  caller has a file name but no directory name ready.
  Should the #warning even be a #error? I mean do we want to release
  binaries which don't guarantee any durability?
sql/log.cc:
  a TODO for the future.
sql/unireg.cc:
  If we sync the frm it makes sense to also sync its creation in the
  directory.
storage/maria/ma_control_file.c:
  control file is vital, try to make it to disk

    #warning to warn (!) about current issues in the pagecache hindering
    checkpoint (we will have to fix them!).


mysys/mf_pagecache.c:
  fix for compiler warning (signed-ness).
  #warning to warn (!) about current issues in the pagecache hindering
  checkpoint (we will have to fix them!).

Moving the test_pagecache_ tests from mysys to unittest/mysys.
Means fixing includes to work with the new directory, some Makefile.am
editing, replacing memset() with bfill().
test_page_cache_*.c renamed to mf_pagecache_*-t.c (-t is the standard
suffix for tests in the mytap protocol).
Also added plan() and exit_status() calls to tests.
Sanja, I put some TODOs for you at the start of mf_pagecache_*.c


unittest/mysys/test_file.h:
  Rename: mysys/test_file.h -> unittest/mysys/test_file.h
mysys/Makefile.am:
  pagecache test files move to top/unittest/mysys
mysys/mf_pagecache.c:
  my_bit.h needed to compile.
unittest/mysys/Makefile.am:
  INCLUDES is a better place for includes than AM_CPPFLAGS (the latter
  get overriden by prog_CPPFLAGS, which is not desirable here).
  Adding pagecache's test programs (moved from mysys);
  test_pagecache_* has been renamed to mf_pagecache*-t
  (-t is the required suffix for test executables in the mytap framework).
unittest/mysys/mf_pagecache_consist.c:
  fixing includes to work with the new directory.
  The test must return an exit code informing if any part failed.
  TODOs for Sanja.
unittest/mysys/mf_pagecache_single.c:
  fixing includes to work with new directory.
  adding a plan() to account for the number of tests.
  Adding exit_status() to tell how many tests failed.
  memset() was giving a compilation warning (implicit declaration etc),
  properly due to me removing stdio.h etc, so I replaced it with bfill().
  TODOs for Sanja.
unittest/mysys/test_file.c:
  moved from mysys (piece of the page cache tests) and includes fixed.

storage/maria/trnman.c:
  fix for a bug (i has to be in [1..SHORT_TRID_MAX])
storage/maria/unittest/ma_control_file-t.c:
  corrupted checksum is in buffer[0], not in buffer[1]

"Changing MI_KEY_BLOCK_LENGTH makes a wrong myisamchk"
in the Maria tree as it is really needed to get "ma_test_all" to pass
(this bug showed up in Maria first, not in MyISAM).
Now ma_test_all does not have corruption messages about test2 anymore,
and shows the same output as mi_test_all except that
ma_test_all has this at the start:
lt-maria_chk: MARIA file test1
lt-maria_chk: warning: Size of indexfile is: 8192          Should be: 16384
MARIA-table 'test1' is usable but should be fixed
This was already true before importing the bugfix.
Wonder if normal.
NOTE: this bugfix is currently in 5.1-engines, in a few days
will be in the main 5.1, then we'll merge 5.1
into Maria: this will merge the bugfix into storage/myisam, but there
will be no need to apply it to storage/maria again. I just couldn't
wait a few days for the 5.1-engines->5.1 merge to be allowed.
