Difficult to debug due to lacking report
This does not solve the real issue, but extracts server log when it happens
Forst commit was incomplete, didn't cover all cases
- Remove the "hack" from mtr.pl that skipped searching for the .dll files
when embedded and windows. Now the variables will be preoperly initialized.
- Make the tests detect that they can't run on windows+embedded
Backport from 6.0 to 5.1.
Only those sync points are included, which are used in debug_sync.test.
The Debug Sync Facility allows to place synchronization points
in the code:
open_tables(...)
DEBUG_SYNC(thd, "after_open_tables");
lock_tables(...)
When activated, a sync point can
- Send a signal and/or
- Wait for a signal
Nomenclature:
- signal: A value of a global variable that persists
until overwritten by a new signal. The global
variable can also be seen as a "signal post"
or "flag mast". Then the signal is what is
attached to the "signal post" or "flag mast".
- send a signal: Assign the value (the signal) to the global
variable ("set a flag") and broadcast a
global condition to wake those waiting for
a signal.
- wait for a signal: Loop over waiting for the global condition until
the global value matches the wait-for signal.

or in the worklog entry.

can be interpreted as a shell metacharacter in some circumstances.
For example, it is interpreted as a command separator when invoking
a debugger.
mysql-test/lib/mtr_cases.pm:
Use ':' as the separator on non-Windows platforms.
mysql-test/mysql-test-run.pl:
Remove unnecessary use of the separator.
in an ".opt" file are defined to some value (even
if it is empty). Without this, a test suite run
aborted on Windows for "embedded".
This fix was applied dusing the build of 5.4.2-beta.
mysql-test/mysql-test-run.pl:
From the code (function "envsubst()"), it is obvious
that any variable which is used in an ".opt" file needs
to be defined.
If the value is wrong, starting the server may fail -
but if the variable is undefined, the whole test suite
will abort.
So variables which are used in an ".opt" file should
always be defined to some value, even if it is blank.
This fix may be overkill, I did not check in detail
whether all these variables are really used in an ".opt"
file - but some are.
Set to one week for testcase and suite timeout
Also set one day timeout for PID file creation (not currently needed in 5.1 but might become, and is needed in azalea)
mysql-test/lib/mtr_cases.pm:
Expand test cases list with test cases to test
InnoDB plugin.
mysql-test/mysql-test-run.pl:
Added "innodb" suite to default list of suites.
mysql-test/suite/innodb/include/have_innodb_plugin.inc:
This file determines if innodb plugin is available.
mysql-test/suite/innodb/my.cnf:
Removed temporary my.cnf, which was added for testing. Not
needed anymore - options are substituted by mtr.
mysql-test/suite/innodb/t/innodb-analyze.test:
This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-timeout.test:
This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-use-sys-malloc-master.opt:
Use "loose" prefix with mysqld options. This makes this
test skipped properly when no innodb is available.
mysql-test/suite/innodb/t/innodb-use-sys-malloc.test:
This test can only be run with InnoDB plugin.
mysql-test/suite/innodb/t/innodb-zip.test:

Remove custom DLL loader code from innodb plugin code, use
symbols exported from mysqld.
storage/innodb_plugin/handler/ha_innodb.cc:
Remove a Win32 workaround for current_thd.
The original problem that innodb plugin used
value of TLS variable across DLL boundaries is
solved in MySQL server (current_thd is a function
not TLS variable now)

Remove custom delay loader
storage/innodb_plugin/handler/handler0vars.h:
Remove custom delay loader

Remove custom delay loader
storage/innodb_plugin/plug.in:
Remove commented out MYSQL_PLUGIN_STATIC,
CMake would not parse that correctly
UNIX sockets need to be on a path shorter than 70 characters on some older platofrms.
MTRv1 tries to fix this by moving the socket to the $TMPDIR, however this causes
issues with certain tests on Windows.
Fixed by not applying any hacks on Windows - Windows does not need them.
