Problem: logging queries not using indexes we check a special flag which
is set only at the server startup and is not changing with a corresponding
server variable together.
Fix: check the variable value instead of the flag.
long shared-memory-base-names could overflow a static internal buffer
and thus crash mysqld and various clients. change both to dynamic
buffers, show everything but overflowing those buffers still works.
The test case for this would pretty much amount to
mysqld --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --shared-memory=1 &
mysqladmin --no-defaults --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX shutdown
Unfortunately, we can't just use an .opt file for the
server. The .opt file is used at start-up, before any
include in the actual test can tell mysqltest to skip
this one on non-Windows. As a result, such a test would
break on unices.
Fixing mysql-test-run.pl to export full path for master
and slave would enable us to start a server from within
the test which is ugly and, what's more, doesn't work as
the server blocks (mysqltest offers no fire-and-forget
fork-and-exec), and mysqladmin never gets run.
Making the test rpl_windows_shm or some such so we can
is beyond ugly. As is introducing another file-name based
special case (run "win*.test" only when on Windows). As is
(yuck) coding half the test into mtr (as in, having it
hand out a customized environment conductive to the shm-
thing on Win only).
Situation is exacerbated by the fact that .sh is not
necessary run as expected on Win.
In short, it's just not worth it. No test-case until we
have a new-and-improved test framework.
- Add build configuration parameter EMBEDDED_ONLY which will configure
the VS solution to produce only mysql embedded binary.
- Make necessary updates to successfully compile solution.
In many cases, binaries can no longer dump core after calling setuid().
Where the PR_SET_DUMPABLE macro is set, use the prctl() system call
to tell the kernel that it's allowed to dump the core of the server.
If we have lower_case_table_names == 2 (usually on case insensitive file
systems) we sometimes make 'homedir' part of the path sent to the
handler into lowercase. So in this case HEAP engine couldn't properly
find and remove HP_SHARE, what caused the bug.
When a Windows console application that has an open console (e.g. mysqld-nt
started with the --console option) encounters certain type of errors
(like no floppy disk in a floppy drive) the OS will pop-up an
"abort/retry/ignore" dialog and block the application (depending on a
registry setting : see http://msdn2.microsoft.com/en-us/embedded/aa731206.aspx
for details).
Fixed by disabling the dialog popups for every error except a GPF and
alignment errors. This is safe to do as the actual error gets reported
(and handled) to mysqld.
- A race condition caused brief unavailablility when trying to acccess
a table.
- The unprotected variable 'grant_option' wasn't intended to alternate
during normal execution. Variable initialization moved to grant_init
a lines responsible for the alternation are removed.
