option leaves the database in inconsistent state,
Analysis: Problem was that atomic writes variable had incorrect
type on same places leading to fact that e.g. OFF option was
not regognized. Furthermore, some error check code was missing
from both InnoDB and XtraDB engines. Finally, when table is
created we have already created the .ibd file and if we can't
set atomic writes it stays there.
Fix: Fix atomic writes variable type to ulint as it should be.
Fix: Add proper error code checking on os errors on both InnoDB
and XtraDB
Fix: Remove the .idb file when atomic writes can't be enabled
to a new table.
special builds UNIV_PAGECOMPRESS_DEBUG and UNIV_MTFLUSH_DEBUG).
Added a new status variable compress_pages_page_compression_error to count possible
compression errors.
Analysis: This was merge error on file fil0fil.cc. fil_system mutex was taken twice because of this.
Fix: Remove unnecessary mutex_enter and fixed the issue with slow posix_fallocate usage.
unnecessary. There is a lot more index pages than there is normal pages.
Earlier all pages were compressed and this provided best performance and
compression ratio. Added status variable to show how many non index pages
are written.
Fixed issue on multi-threaded flush at shutdown.
Removed unnecessary startup option innodb_compress_pages.
Added a new startup option innodb_mtflush_threads, default 8.

* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
- Reset static variables that are used to signal "init done" for DBUG, in dbug_end()
- Set string server variables to NULL after memory for the value is freed - avoids double free()
- fix DBUG_ASSERTs that happened during reinitialization.
Changed implementation os_file_rename() on Windows such as it does not fail if destination file already exists. Now MoveFileEx() with MOVEFILE_REPLACE_EXISTING flag is used, instead of prior MoveFile().
This fixed implementation is better compatible with rename() on POSIX systems.
- Better error messages
This fixes that one again can run the test systems with many threads without having to increase fs.aio-max-nr.

Continue without AIO even if we can't allocate resources for AIO
