Problem was that we checked for existing connection in stmt_close
and did not free(stmt) if it's closed (that didn't work well with
embedded)
I just added new flag to the stmt_close and now we check it instead
of connection
This ensures that my_file_info takes this the max number of files into account and one can now use --open-files-limit on windows to increase number of used files up to 2048
Done clean-up in prep stmt API functions:
1) Removed some checks that were performed only in debug version
were making debug version more tolerable to user errors than
production (and thus caused problems for example masking some
bugs).
2) Also removed some other checks to make prep stmt API
consistent with the rest of C API (this also in line with
general politics - make checks in only those places where
errors are very common and hard to spot).
now mysql_server_init is called from mysql_init with fake parameters
mysql_once_init code included to mysql_server_init.
embedded-specific initialization is in init_embedded_server function
mysql_server_init() now returns error code if something went wrong (Bug #2062)
Don't use my_fopen() when reading symlink information as this may cause problems when a lot of files are opened.
Free thread keys with pthread_key_delete() instead of relying on automatic free. (Bug #2062)
Fixed bug in UNION statement with alias '*'. (Bug #1249)
Fixed a bug in DELETE ... ORDER BY ... LIMIT where the rows where not deleted in the proper order. (Bug #1024).
FOUND_ROWS() could return incorrect number of rows after a query with an impossible WHERE condition.
HOW DATABASES doesn't anymore show .sym files (on windows) that doesn't point to a valid directory. (Bug #1385)
It happens that mysql->client_next->client_next=mysql
and mysql_close() goes into infinite loop.
Results vary from simple sigsegv (FreeBSD), to hard system lockup (Linux)
:)
Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler)
Added a lot of 'version_xxx' strings to 'show variables'
Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris)
Fixed problem with printing sub selects to debug log
Client option secure-auth deployed on all possible layers:
- mysql client command-line and config file option
- mysql_options option MYSQL_SECURE_AUTH
- mysql_real_connect will automatically take into account that option if
mysql->options.my_cnf_file/my_cnf_group is set
