Make individual scripts the unit of ownership for theme contributions
so that loading a script that calls weechat.theme_register(...) and
later unloading it correctly removes the script's overrides.
Plugin API addition (weechat-plugin.h):
- new function pointer t_weechat_plugin.theme_unregister_script
delegates to core's theme_unregister_script.
- new convenience macro weechat_theme_unregister_script(script).
- WEECHAT_PLUGIN_API_VERSION bumped to 20260527-02.
Script API additions (plugin-script-api.{c,h}):
- new plugin_script_api_theme_register (plugin, script, name,
overrides) forwards to the plugin API with the script pointer
as the contribution owner, so contributions are tracked
per-script (not per script-language plugin).
Lifecycle wiring (plugin-script.c):
- new file-local plugin_script_remove_themes (plugin, script)
calls weechat_theme_unregister_script.
- plugin_script_remove now calls it alongside the other
plugin_script_remove_* helpers, so script-unload tears down
everything (configs, bar items, themes, hooks).
Eight language bindings updated to call
plugin_script_api_theme_register instead of weechat_theme_register
directly, so they pass the script pointer as owner:
- python, perl, ruby, lua, tcl, javascript, php, guile.
The behavior change is end-to-end visible only at script unload:
before, an unloaded script's theme overrides lingered in the
registry forever and would be re-applied on the next /theme apply;
after, they vanish when the script unloads. /plugin unload of an
entire script-language plugin already worked via commit 24's hook
in plugin_remove (which drops both plugin-only contributions and
their script-owned children when the language plugin itself goes
away, because the contribution's plugin pointer matches).
No new unit tests in this commit: the underlying theme_unregister_script
function is covered by TEST(CoreTheme, UnregisterByOwner), and the
remaining changes are plumbing.
This reverts commit e64ab3c675.
This was causing incorrect conversion of strings "0x..." to pointers on systems
like Solaris/illumos.
And as a side effect, buffers were sometimes empty in weechat relay clients
like glowing-bear.
This should definitely fix the crash with Python 3.12, even when scripts are
auto-loaded (the previous fix was working only when the scripts are loaded
manually).
This prevents a crash in some scripts that could use options after they are
freed, with the call to hook config callback that has been enabled by commit
2260214797.
This fixes an issue with IRC URL given on command line when it starts with
`ircs://` or `irc6://`: the server is not created at all (only `irc://` works
fine).
