Reserve the MySQL LOCK_thread_count mutex when printing thd->query of
an arbitrary transaction; if we are printing thd->query of a transaction that
we know is currently executing inside InnoDB, then we know that MySQL cannot
meanwhile change thd->query, and no need to reserve the MySQL mutex; note
that this patch still leaves open the possibility of races in MySQL's
thd->query_len
Fix assertion failure on line 713 of row0upd.c if there is a column prefix index and the last characters in the prefix are spaces: do not assume that the length of alphabetically equal strings is the same; fix a buglet which could cause InnoDB to think that a secondary index record was not locked though it had been updated in a way which did not alpahabetically change its value, e.g., abc -> aBc
Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed
libraries always ended up in "dir..", even though they were not supposed
to be installed anyway (they are only required at link time). Fixed it by
replacing libs_LIBRARIES with noinst_LIBRARIES for all InnoDB Makefile.am
files and by removing "libsdir = " from innobase/include/Makefile.i .
Fix hang introduced by selective deadlock resolution
srv0srv.c, row0mysql.c:
Fix hang introduced by selective deadlock resolution + corruption caused by lock timeout or sel deadl res in ON DELETE CASCADE
Merge InnoDB-4.0.5: new isolation levels READ COMMITTED and READ UNCOMMITTED now supported, selective deadlock resolution
mysqld.cc:
Change MySQL default isolation level to REPEATABLE READ; note that InnoDB has always had that default, and BDB and MyISAM always run at SERIALIZABLE level anyway
Fix bug: if SHOW INNODB STATUS or innodb_monitor printed several hundred transactions, the output was truncated and we forgot to release the kernel mutex
Redefine sprintf as ut_sprintf inside InnoDB code; some old Unixes may have a pointer as the return type of sprintf
lock0lock.c:
Add safety against buffer overruns in latest deadlock info
srv0srv.c:
Add safety against buffer overruns in SHOW INNODB STATUS
os0thread.h, os0thread.c:
Fix a portability bug introduced in Windows when we changed os_thread_id_t to be the same as os_thread_t
