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:
- key alt-j alt-r is reintroduced to open IRC raw buffer
- command "/server raw" opens IRC raw buffer
- new option irc.look.raw_messages, which is number of lines to keep in memory
to display when user will open raw buffer (to see last messages received before
opening raw buffer)
The "irc/debug" buffer is displayed when IRC debug is enabled (with "/debug irc" thru debug plugin).
If the buffer is closed, it is reopen when new messages are written, until debug is disabled by user (with "/debug irc").
