To allow to use different configuration directories for MariaDB and MySQL,
configuration files from MYSQL_HOME environment variable will be
processed only, if MARIADB_HOME environment variable was not set.
Exclude definitions from my_config.h that conflict with server's config.h
(most of ma_config.h is not used by connector anyway)
Avoid overriding server's SIGN_TARGET() macro, if used as subproject.
Make WITH_UNIT_TESTS exclude unit tests, like it is for the server.
* do not read ini_exts array beyond the end
* do not use local variable (val) address outside of the variable's scope
* do not read $HOME/my.cnf
* do not create files in the user's $HOME, use $MYSQL_TMP_DIR
* test reading of the executable name group
* fail the test if .my.cnf cannot be opened
If no configuration file and no configuration group was specified, Connector/C ddoesn't read any configurationm files.
By default the follwing groups will be read:
- client
- client-server
- client-mariadb
If no configuration file was specified, Connector/C looks up for configuration files in following locations:
- Windows:
- System directory
- Windows directory
- C:\
- Directoy from which the application was started
- MYSQL_HOME environment variable
- Unix platforms
- DEFAULT_SYSCONFIR (if specified)
or
- /etc and /etc/mysql
- MYSQL_HOME environment variable
- .my.cnf in home directory
Special case: If NULL or empty string will be passed for MYSQL_READ_DEFAULT_GROUP option Connector/C will read the default groups and the group which matches the application name.
