Changed the semantics of open_count so that it is decremented
at every unlock (if it was incremented due to data changes).
So it indicates a crash, if it is non-zero after a lock.
The table will then be repaired.
This bug is the result of weird error happening with mi_float8get and double
arythmetic. I described that in 'Bug that looks potentially dangerous' email
used in the handle_options() function (instead of using additional
handle_option() parameter). The default value of the
my_getopt_error_reporter is default_reporter(). One can set it to
other functions if case of need.
Fix for binary collations for MyISAM and HEAP BTREE.
This patch also changes trailing spaces behaviour for
binary collations. Binary collations now have PAD
characteristic too.
Added declarations for print_msg_to_log and vprint_msg_to_log. sql_print_error are simple functions that wrap calls to print_msg_to_log. Define the different error types with MY_ERROR_TYPE, MY_WARNING_TYPE, and MY_INFORMATION_TYPE
gen_lex_hash.cc:
Added NULL error reporting parameter to handle_options
log.cc:
Add print_msg_to_log, print_buffer_to_log, and vprint_msg_to_log. Print_msg_to_log will write the message to the windows event log if on NT. We now have error, warning, and information versions of sql_print_xxxx. T his is a variation of a similar changeset WAX did.
mysqld.cc:
Added option_error_reporter callback function and pass that into handle_options
mysql.cc:
Added NULL as error reporter arg to the end of handle_options
Many files:
Added NULL error reporter parameter as the last paramter to handle_options
my_getopt.c:
Added second function pointer to server as an error reporting callback. Added local function report_option_error that will either write the error to stderr or to the error reporting callback. changed all calls in handle_options from fprintf(stderr, ... ) to report_option_error
my_getopt.h:
Changed declaration of handle_options to use typedefs for the two function pointers. added second function pointer to server as an error reporting callback
mysqld.dsp:
Added custom build step for compiling message file and added message resource file (output of mc)
required autotools macro written and deployed in all apropriate Makefile.ams.
Use cases checked:
- linux, standard location of zlib, no ndb
- linux, standard locatoin of zlib, with ndb
- linux, non-standard location of zlib, no ndb
- hpux11, use of bundled zlib, no ndb
The only non-checked case is non-standard location of zlib (or use of bundled
zlib) + ndb. I wasn't able to check it as ndb/ just won't compile on beasts
like AIX52 or HPUX11, where such a check is possible. It didn't compile
there before as these systems dont't have installed zlib, so nothing got broken ;)
more logical table/index_flags
return HA_ERR_WRONG_COMMAND instead of abstract methods where appropriate
max_keys and other limits renamed to max_supported_keys/etc
max_keys/etc are now wrappers to max_supported_keys/etc
ha_index_init/ha_rnd_init/ha_index_end/ha_rnd_end are now wrappers to real {index,rnd}_{init,end} to enforce strict pairing
The bug was caused by error in hash calculation function: it
always returned hash value for last field in a composite key, so
for keys like (a text, b char(1)) we were always
getting bad hash values.
