If MySQL wrote to its binlog, but for some reason trx->update_undo and trx->insert_undo were NULL in InnoDB, then trx->commit_lsn was garbage, and InnoDB could assert in the log flush of trx_commit_complete_for_mysql() (Bug #9277)
dict_load_table(): Remove the check for row_format=compact for now,
because the flag bit we used (high-order bit of mix_len)
has not been zero for at least two customers.
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 the previous bug fix: dropping a table with FOREIGN KEY checks running on it caused a cascade of failed drops while the foreign key check was waiting for a lock
Fix bug: if we dropped a table where an INSERT was waiting for a lock to check a FOREIGN KEY constraint, then an assertion would fail in lock_reset_all_on_table(), since that operation assumes no waiting locks on the table or its records
row0mysql.c:
Fix bug: InnoDB failed to drop a table in the background drop queue if the table was referenced by a foreign key constraint
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
Fix for the 0xA0 character problem in the InnoDB FOREIGN KEY parser: if my_isspace() treats 0xA0 as space, then let InnoDB do the same; this might break some multi-byte charset id's, though for big5, ujis, sjis this seems not to change the current behavior (I checked the tables in /share/charsets); this fix must NOT be merged to 4.1 because in 4.1 everything is in UTF-8
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 #3478: InnoDB's FOREIGN KEY tables treated table and database names as case-insensitive; RENAME TABLE t to T would hang in an endless loop if t had a foreign key constraint defined on it
dict0dict.c:
Fix bug #3478: InnoDB's FOREIGN KEY tables treated table and database names as case-insensitive; RENAME TABLE t to T would hang in an endless loop if t had a foreign key constraint defined on it; fix also a hang that would occur if one tried in ALTER TABLE or RENAME TABLE to create a foreign key constraint name that collided with another existing name
Add typecast from ulint to ssize_t in pread and pwrite, so that the type is according to the Linux man page; this will probably not help to fix the HP-UX 32-bit pwrite failure, since the compiler should do the appropriate typecasts anyway
Fix bug #5960: if one updated a column so that its size changed, or updated it to an externally stored (TEXT or BLOB) value, then ANOTHER externally stored column would show up as 512 bytes of good data + 20 bytes of garbage in a consistent read that fetched the old version of the row
Fix bug #5180: having a column prefix index in the primary key, and the same column fully in a secondary key could cause an assertion failure in row_build_row_ref()
Improve the comment on stored_select_lock_type
ha_innodb.cc:
Let InnoDB remember select_lock_type inside LOCK TABLES, also over plain consistent read SELECTs; fix Bug #5538 : assertion failure when using mysqldump with the -l option; in MERGING this patch to 4.1, there may be PROBLEMS; that is because previous patch was never merged to 4.1; Heikki Tuuri has to polish the code in 4.1 after this patch has been merged.
Add more precise diagnostics about the state of the I/O threads of InnoDB; print in SHOW INNODB STATUS if the event wait semaphore of each I/O thread is set
Fix bug: if there was little file I/O in InnoDB, but the insert buffer was used, it could happen that 'Pending normal aio reads' was bigger than 0, but the I/O handler thread did not get waken up in 600 seconds. This resulted in a hang, and crashing of InnoDB.
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:

Fix bug: if we RENAME a table, InnoDB forgot to load the foreign key constraints that reference the new table name, and forgot to check that they are compatible with the table
