Before this fix, opening a configuration file located under "~" failed.
To evaluate the "~" path, home_dir needs to be initialized.
The 'home_dir' variable was initialized too late in my_init().
This fix:
- moved the home_dir initialization from my_init() to my_basic_init(),
using getenv("HOME"))
- moved the initialization of my_umask / my_umask_dir also to
my_basic_init(), to have all the my_umask / my_umask_dir init code in the
same place.
The second part is not strictly required, but makes the code more
maintainable.
Tested the fix manually.
No MTR tests added, because MTR should not access or modify the $HOME
directory of the user running tests.
Windows and Solaris
Reviewed every call to my_error() using the va_args parameters,
to make sure the arguments type are ok.
Fixed the broken calls to my_error() to pass a strings as 'char *',
not LEX_STRING.
When compiling wiht ./configure --with-ssl=/usr,
which used OPEN_SSL but not YASSL, the code in sql/mysqld.cc
failed to build because of an incomplete performance schema instrumentation.
This fix implements properly the instrumentation for the rwlock
used in openssl_lock_t.
Verified that the code builds, and the ssl + performance schema tests
do pass.
Problem: The test case failed because: (i) warning text in
result file differed from the warning output by the
server, and (ii) binlog contents in result file did
not show the statements logged wrapped in BEGIN/COMMIT
as it is the case after WL 2687.
Solution: We update the result file, but first we change the
unsafe warning text to also refer to performance_schema
table(s). This required changing the result files for
existing test cases that provide output for warnings
related to ER_BINLOG_UNSAFE_SYSTEM_TABLE. "Grepping" in
result files, shows that only binlog_unsafe contained
reference to such a warning.
We also update the result file with the missing
BEGIN/COMMIT statements.
When starting mysqld it did not recognize most of the options given on
the command line when it was compiled for 32-bit Solaris using Sun
Studio compiler. The cause for this was that most of the entries in
the my_long_options array contained "garbage" data. The garbage data
was caused by a compiler bug. When initilizing the def_value member
for the "default-storage-engine" entry it was initialized like this:
(longlong)"MyISAM"
i.e. casting a 32 bit pointer to a 64 bit integer value. Due to the
compiler bug only 4 bytes was allocated (instead of 8 bytes). This
caused everything following this entry to be stored at a location that
was 4 byte wrong.
The fix/work-around for this problem is initialize the def_value
for default-storage-engine in my_long_options to 0 and instead
initialize the default_storage_engine variable to "MyISAM" in
init_common_variables().
