At the moment, building WeeChat triggers several thousand -Wstrict-prototypes
diagnostics. This is due to its source code using an empty argument list for
functions and function pointers that take no arguments, instead of explicitly
declaring that they take no arguments by using a void list.
This commit replaces all empty argument lists with a void list.
Note that Ruby's headers also suffer the same problem, which WeeChat can't
do anything to fix. Thus, building WeeChat with the Ruby plugin enabled
will still issue approximately 30 such diagnostics.
In addition to searching the statically configured WEECHAT_LIBDIR
(weechat's installation directory) for plugins, search the path
given in the environment variable WEECHAT_EXTRA_LIBDIR. This makes
departing from the FHS standard while keeping the plugins packaged
separately easier. This change was made specifically with the Nix
package manager in mind, but can easily be used by others.
This pointer is the first argument received by callbacks, and the
existing argument "data" is now automatically freed by WeeChat when the
object containing the callback is removed.
With this new pointer, the linked list of callbacks in scripts has been
removed. This will improve speed of scripts (using a lot of hooks),
reduce memory used by scripts and reduce time to unload scripts.
Following functions are affected in the C API:
* exec_on_files
* config_new
* config_new_section
* config_new_option
* hook_command
* hook_command_run
* hook_timer
* hook_fd
* hook_process
* hook_process_hashtable
* hook_connect
* hook_print
* hook_signal
* hook_hsignal
* hook_config
* hook_completion
* hook_modifier
* hook_info
* hook_info_hashtable
* hook_infolist
* hook_hdata
* hook_focus
* unhook_all_plugin
* buffer_new
* bar_item_new
* upgrade_new
* upgrade_read
New features:
- add optional hdata name for variables in hdata
- add plugin API functions: hdata_get_var_hdata
- use hashtable to store hdata (created by WeeChat and plugins)
- free hdata and infolists created by plugin on plugin unload
- free all hdata on exit
- add "free" option to command /debug hdata
- remove hdata for hooks
