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)

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
Do not add + 1 to the InnoDB index cardinality estimate if the B-tree just contains one page; the fix made in March 2004 caused InnoDB systematically to overestimate the cardinality of empty or small tables by 1
InnoDB with UNIV_MEM_DEBUG did not compile because a global variable was forgotten when we put back mem_print_info() functions 2 days ago; add that variable
Put back mem_print_info() functions that are used to analyze memory leaks; Marko removed them by accident in his Feb 20th, 2004 patch; these functions are very important for debugging, and should always be kept in the source code base
Revert the patch that put log debug code behind UNIV_LOG_DEBUG
log0log.ic, log0recv.c, log0log.c, log0log.h:
Revert 1.1730.18.1 about UNIV_LOG_DEBUG: debug code is often needed in debugging the production version
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
srv0que.c, srv0que.h:
new file
Implement ut_realloc
lexyy.c, pars0lex.l:
Start using ut_malloc, ut_free, ut_realloc in pars0lex.l and lexyy.c; mem_realloc was broken; eliminate possible memcpy(NULL, ..., 0) from string_append()
