HAVE_IBGCC_ATOMIC_BUILTINS=>HAVE_IB_GCC_ATOMIC_BUILTINS.
Due to the typo, detection of atomics was broken.
It also lead to valgrind error during shutdown
(access to freed memory),which is likely present
in all builds where atomics are not used.
Reason: implementation of send/reap in mysqltest uses the same "embedded" connection in a thread different from current, so thread stack has to change when connection is used in different OS thread..
It appears that stack overflow checks for recusrive stored procedure
calls, that run in the normal server, did not work in embedded and were
dummified with preprocessor magic( #ifndef EMBEDDED_SERVER ).
The fix is to remove ifdefs, there is no reason not to run overflow checks
and crash in deeply recursive calls.
Note: Start of the stack (thd->thread_stack variable) in embedded is not
necessarily exact but stil provides the best guess. Unless the caller of
mysql_read_connect() is already deep in the stack, thd->thread_stack
variable should approximate stack start address well.
The bug was that ./configure was passing paramers to subscripts as $@, and to handle embedded spaces it needs
to be quoted as "$@".
This resulting into a bug when ./configure was called e.g with CFLAGS='-m64 -Xstrconst'..
Additionally, fixed cmake/configure.pl did not handle environment variables passed on the command line.
this is fixed in this push
"TYPE=storage_engine" is deprecated, and will be removed
in the Celosia release of MySQL. Since the option is
present in the Betony release and the version number of
Celosia is still not decided, we need to bump the
deprecation version number back up to "6.0".
The problem was because the gettimeofday function was incorrect
implemented for Windows, and so the semisync master did not wait
for slave reply properly on Windows.
Fixed by removing the gettimeofday function for Windows, and using
set_timespec function to get current time for all platforms.
Fix contains of :
- splitting CC/CXX if there are more that 2 space-delimited tokens, add the rest to CFLAGS
(in this case CC was set to "ccache gcc --pipe", and this broke recognition of gcc compiler
as CMake understands CC consisting of 2 space delimited tokens but not more)
- add my_new.cc to mysys fle list if C++ operator new is not found. Always, not only
for gcc (the original problem was that missing operator new when compiling with CXX=gcc)
There was an erroneous parameter when calling flush_master_info
from write_ignored_events_info_to_relay_log which could lead to a
server crash. This happens because the I/O thread releases the
log_lock before calling the flush_master_info.
Set the function to call flush_master_info with third parameter
to true, so that the mutex is properly taken.
The task is to
(a) add a comment on indexes and
(b) increase the maximum length of column, table and the new index comments.
