Ingo's patch:
WL#2936 - Falcon & MySQL plugin interface: server variables
Added initialization for plugin string variables with their
default values.
Added deallocation of string values before a plugin and its
variables is deleted.
Added examples to plugin_example
Added initialization for the plugin structure created in
plugin_add().
Made a correct argument vector in mysql_install_plugin():
handle_options() assumes that arg0 (program name) always exists.
Fixed a compiler dependent expression to be more portable.
Initialized 'dummy' in construct_help_options() so that loaded
plugin show themselves as TRUE in the help output.
- Fix error message to say that "mysql_upgrade" should be run when
a particular error message is found to be missing
- Dont's set default value on blob's - it will not be used anyway.
"Server Variables for Plugins"
Implement support for plugins to declare server variables.
Demonstrate functionality by removing InnoDB specific code from sql/*
New feature for HASH - HASH_UNIQUE flag
New feature for DYNAMIC_ARRAY - initializer accepts preallocated ptr.
Completed support for plugin reference counting.
index_read(), index_read_idx(), index_read_last(), and
records_in_range() - instead of 'uint keylen' argument take
'ulonglong keypart_map', a bitmap showing which keyparts are
present in the key value.
Fallback method is provided for handlers that are lagging behind.
Removed a lot of compiler warnings
Removed not used variables, functions and labels
Initialize some variables that could be used unitialized (fatal bugs)
%ll -> %l
1) Two small windows cleanups for Archive.
2) Patch from Calvin for Falcon to be able to have its own I_S loaded. One example added for this, does hello world.
- Removed not used variables
- Changed some ulong parameters/variables to ulonglong (possible serious bug)
- Added casts to get rid of safe assignment from longlong to long (and similar)
- Added casts to function parameters
- Fixed signed/unsigned compares
- Added some constructores to structures
- Removed some not portable constructs
Better fix for bug Bug #21428 "skipped 9 bytes from file: socket (3)" on "mysqladmin shutdown"
(Added new parameter to net_clear() to define when we want the communication buffer to be emptied)
Fixed some possible fatal wrong arguments to printf() style functions
Initialized some not initialized variables
Fixed bug in stored procedure and continue handlers
(Fixes Bug#22150)
In practice this means that handlerton is now created by the server and is passed to the engine. Plugin startups can now also control how plugins are inited (and can optionally pass values). Bit more flexibility to those who want to write plugin interfaces to the database.
remove #define __attribute__(A) from plugin.h
increase API version because placeholders were added
more robust definition of min_plugin_interface_version
