- InnoDB now returns handler specific HA_WRONG_CREATE_OPTION instead of MySQL specific ER_ILLEGAL_HA_CREATE_OPTION
- This changes the user level error message from "Unknown error" to "Wrong create options"

storage/innobase/handler/ha_innodb.cc:
Return HA_WRONG_CREATE_OPTION instead of ER_ILLEGAL_HA_CREATE_OPTION
This gives more clear and OS indepedent error messages
storage/xtradb/handler/ha_innodb.cc:
Return HA_WRONG_CREATE_OPTION instead of ER_ILLEGAL_HA_CREATE_OPTION
This gives more clear and OS indepedent error messages
- Better error messages
This fixes that one again can run the test systems with many threads without having to increase fs.aio-max-nr.
mysql-test/include/mtr_check.sql:
Ignore the INNODB_USE_NATIVE_AIO variable (may change during execution)

Ignore warnings for failure to setup AIO
storage/innobase/os/os0file.c:
Continue without AIO even if we can't allocate resources for AIO

Continue without AIO even if we can't allocate resources for AIO
storage/xtradb/srv/srv0start.c:
Give an error message (instead of core dump) if AIO can't be initialized

Patch and test case by Patryk Pomykalski
mysql-test/suite/innodb/r/innodb-autoinc.result:
updated test case
storage/innodb_plugin/handler/ha_innodb.cc:
Fixed that we properly reserve values for auto_increment
storage/xtradb/handler/ha_innodb.cc:
Fixed that we properly reserve values for auto_increment
- Use native memcmp() supplied with C runtime instead of hand-unrolled loop ptr_compare_N loop
Prior to fix ptr_compare_0() has 3.7% samples in OLTP-RO in-memory.
Fix brings this down to 1.8% (all memcmp samples)
- Innodb : fix UT_RELAX_CPU to be defined as YieldProcessor, as was also originally intended
(but intention was lost in the #ifdef maze
This reduces number of ut_delay() samples in profile from 1.5% to 0.5%
"relocation R_X86_64_PC32 against `handler_index_cond_check' can not be used when making a shared object; recompile with -fPIC"
don't use visibility=hidden for external functions
Fixed README with link to source
Merged InnoDB change to XtraDB
README:
Added information of where to find MariaDB code
storage/archive/ha_archive.cc:
Removed memset() of rows, a MariaDB checksum's doesn't touch not used data.
common icp callback in the handler.cc.
It can also increment status counters, without making the engine
dependent on the exact THD layout (that is different in embedded).
The comment for the fix commit says:
Due to the changes required by ICP we first copy a row from the InnoDB
format to the MySQL row buffer and then copy it to the pre-fetch queue.
This was done for the non-ICP code path too. This change removes the
double copy for the latter.
a significant performance drop for high concurrency bechmarks
(bug #11765850 - 58854).
Here's the comment of the patch commit:
The bug is that the InnoDB pre-fetch cache was not being used in
row_search_for_mysql(). Secondly the changeset that planted the
bug also introduced some inefficient code. It would read an extra
row, convert it to MySQL row format (for ICP==off), copy the row
to the pre-fetch cache row buffer, then check for cache overflow
and dequeue the row that was pushed if there was a possibility of
a cache overflow.
