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
A symbolic link weechat-curses -> weechat is now created (by both cmake and
configure), so that the /upgrade will work from an old version.
However, if you upgrade from an old version, it is recommended to force the use
of the new binary name with the command: `/upgrade /path/to/weechat` (replace
the path accordingly).
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
