Apply innodb-5.0-ss1696 snapshot
Fixes:
- Bug#20090: InnoDB: Error: trying to declare trx to enter InnoDB
- Bug#23710: crash_commit_before fails if innodb_file_per_table=1
At InnoDB startup consider the case where log scan went beyond
checkpoint_lsn as a crash and initiate crash recovery code path.
- Bug#28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
We need to do some special AUTOINC handling for the following case:
INSERT INTO t (c1,c2) VALUES(x,y) ON DUPLICATE KEY UPDATE ...
We need to use the AUTOINC counter that was actually used by
MySQL in the UPDATE statement, which can be different from the
value used in the INSERT statement.
- Bug#29097: fsp_get_available_space_in_free_extents() is capped at 4TB
Fix by typecasting the variables before multiplying them, so that the
result of the multiplication is of type "unsigned long long".
- Bug#29155: Innodb "Parallel recovery" is not prevented
Fix by enabling file locking on FreeBSD. It has been disabled because
InnoDB has refused to start on FreeBSD & LinuxThreads, but now it
starts just fine.
Apply innodb-5.0-* snapshots: ss1489 and ss1547.
Fixes:
Bug#9709: InnoDB inconsistensy causes "Operating System Error 32/33"
Bug#22819: SHOW INNODB STATUS crashes the server with an assertion failure under high load
Bug#25645: Assertion failure in file srv0srv.c
Bug#27294: insert into ... select ... causes crash with innodb_locks_unsafe_for_binlog=1
Bug#28138: indexing column prefixes produces corruption in InnoDB
NULL MERGE: this ChangeSet will be null merged into mysql-5.1
Fixes:
- Bug #26662: mysqld assertion when creating temporary (InnoDB) table on a tmpfs filesystem
Fix by not open(2)ing with O_DIRECT but rather calling fcntl(2) to set
this flag immediately after open(2)ing. This way an error caused by
O_DIRECT not being supported can easily be ignored.
- Bug #23313: AUTO_INCREMENT=# not reported back for InnoDB tables
- Bug #21404: AUTO_INCREMENT value reset when Adding FKEY (or ALTER?)
Report the current value of the AUTO_INCREMENT counter to MySQL.
Bug #27381: InnoDB exits when attempting to rename table to non-existant database
Fix Bug#27381 by calling os_file_handle_error_no_exit() instead of
os_file_handle_error().
Fixed bugs:
BUG#15991: "innodb-file-per-table + symlink database + rename = crash"
BUG#15650: "DELETE with LEFT JOIN crashes server"
BUG#15308: "Problem of Order with Enum Column in Primary Key"
BUG#14189: "VARBINARY and BINARY variables: trailing space ignored"
data files. Previously, writes were flushed until the doublewrite
buffer was created. That would be too slow on systems where
os_file_flush() [or fsync(2)] is slow. (Bug #12125)
Gluh's SESSION/GLOBAL for @variables fix in sql_yacc.yy and
Bar's well_formed_len() changes in ndb code
did not make it and should be re-applied manually
between two server instances at server shutdown/startup.
This conflict on advisory locks appears to be the result of a bug
in the operating system; these locks should be released when the
files are closed, but somehow that does not always happen
immediately in Linux. (Bug #9381)
AIX 5.1 after security patch ML7 seems to contain a bug that instead of EEXIST it sets errno to 0 if a file creation fails because the file already exists. Work around that bug by interpreting errno 0 in AIX as EEXIST.
Fix Windows porting bugs that broke ibbackup: 1) wrong error check in for CreateDirectory(), 2) wrong error check if the file did not exist in DeleteFile(), 3) too strict sharing restrictions in os_file_create_simple(): when ibbackup called that function, it would not allow mysqld to write to the file
We accidentally checked if the DIRECTORY is of type OS_FILE_TYPE_UNKNOWN; our intention was to check if the FILE is that; best to remove the check altogether, as in crash recovery it is safest to try to open also files whose type is unknown
os0file.c:
Fix a bug: in Windows, os_file_readdir_next_file() returned OS_FILE_TYPE_UNKNOWN as the type of a regular file; this did not break mysqld, but did break ibbackup on Windows
at run-time, so that an executable compiled on Mac OS X 10.2 can
be run on Mac OS X 10.2 (without the work-around) and Mac OS X 10.3
and later with the work-aroud enabled.
Use the fcntl() file flush method on OS X; Apple disabled fsync() for internal disk drives, which caused corruption in power outages; the patch was recommended by an Apple engineer
Fix InnoDB bug: on HP-UX, with a 32-bit binary, InnoDB was only able to read or write <= 2 GB files; the reason was that InnoDB treated the return value of lseek() as a 32-bit integer; lseek was used on HP-UX-11 as a replacement for pread() and pwrite() because HAVE_BROKEN_PREAD was defined on that platform
Let MySQL check the existence of readdir_r with 3 arguments; Solaris seems to have just 2 args
Check the existence of readdir_r and localtime_r; even though MySQL does check these too, we need our own check for Hot Backup code
os0file.c:
Use re-entrant readdir_r where available
ut0ut.c:
Make a function to use thread-safe localtime_r where available; that particular function was not called from anywhere, though
