table' lockup".
Changes from the innodb-4.1-ss11 snapshot.
Do not call os_file-create_tmpfile() at runtime. Instead, create
a tempfile at startup and guard access to it with a mutex.
Also, fix bugs:
10511: "Wrong padding of UCS2 CHAR columns in ON UPDATE CASCADE";
13778: "If FOREIGN_KEY_CHECKS=0, one can create inconsistent FOREIGN
KEYs". When FOREIGN_KEY_CHECKS=0 we still need to check that
datatypes between foreign key references are compatible.
Also, added test cases (also for bug 9802).
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)
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.
Print a more descriptive error and refuse to start InnoDB if the size of ibdata files is smaller than what is stored in the tablespace header; innodb_force_recovery will override this
Fix InnoDB critical bug #7496; we scan the InnoDB data dictionary also at a normal mysqld startup, and create the spaces, so that we know the mapping space id -> .ibd file name; fix an infinite loop if DISCARD TABLESPACE coincides with INSERT or some other table operation; fix a potential crash if DISCARD TABLESPACE coincides with a cascaded FOREIGN KEY operation in the same table; do not allow DISCARD TABLESPACE of a referenced table if FOREIGN_KEY_CHECKS=1
srv_printf_innodb_monitor(): Removed extraneous rewind() call.
The caller of this function calls rewind() if necessary.
In this way, we avoid rewind()ing stderr in
srv_lock_timeout_and_monitor_thread().
Fix bug #6817 and bug #6827 : do not crash the server if the buffer pool becomes filled by the locks of ONE huge transaction, return error 1206 instead; do not crash the server, but return error if we cannot allocate memory for the buffer pool at a mysqld startup
Simple optimzations and cleanups
Removed compiler warnings and fixed portability issues
Added client functions 'mysql_embedded()' to allow client to check if we are using embedded server
Fixes for purify
If innodb_thread_concurrency would be exceeded, let a thread sleep 10 ms before entering the FIFO queue; previously, the value was 50 ms, which Peter Z considered too long
Fix bug #5414 in 4.1: srv_max_n_threads was always set to only 1000, regardless of the buffer pool size; undelr very high concurrent loads this could cause an assertion failure in sync0arr.c line 384 when we ran out of wait slots for threads; also innodb_thread_concurrency did not work, because the wait queue also there overflowed at 1000 concurrent threads; also remove redundant code
trx0undo.c:
Add a missing newline to fprints
Change a reference to ibman.php to a reference in the MySQL manual; someone should change the 20 other places in the source code where we still refer to ibman.php
Changes for NetWare to exit the InnoDB gracefully instead of crashing the server (patch by PRam@novell.com, polished a little by Heikki Tuuri)
mysqld.cc, ha_innodb.cc:

next-key locking. Using this option the locks InnoDB sets on index
records do not affect the ``gap'' before that index record. Thus, this option
allows phantom problem.
Revert Marko's untested changeset 1.1844.1.6 to the stable 4.0 version; stable 4.0 must NOT BE modified except in case of bugs
