Expanded ignored codepoints during highlight token comparison to include zero-width joiner (U+200D) in addition to variation selectors (U+FE0E/U+FE0F), which helps emoji entered from different input methods still match configured “extra highlight words.”
This logic is used by the alert/highlight matching path (alert_match_word) that compares configured extra words against extracted message tokens.
Improved token scanning to use UTF-8-aware character classification (gunichar, g_unichar_isdigit, g_unichar_isalpha) instead of byte-only checks, avoiding split/mis-detection on multibyte characters.
Integrated STS capability handling and connection lifecycle hooks (ignore CAP DEL, trigger upgrades, reschedule on disconnect, new server fields).
Initialized and cleaned up STS state during startup/shutdown to persist policies across sessions.
Cutting off all text after \001 can result in users hiding text
so lets only bother handling it if it is a valid CTCP message
(starting and ending with \001).
If ptr[0] is NULL, then strchr may return a pointer to the NULL
terminator for serv->nick_prefixes, making the if statement true, which
then leads to the pointer increment leaving ptr oob. Now we check to
ensure ptr[0] != NULL.
From the Linux manpages for strchr:
The terminating null byte is considered part of the string, so that if c is
specified as '\0', these functions return a pointer to the terminator.
- Combine the three properties into a single one
- Finally fully fix the handling with plugins handling events
TODO: Look into lastact handling of these, seems wrong
It just duplicates functionality and this fixes:
- alert_taskbar chanopt not being respected
- tab color being incorrect when highlight print events are eaten
- AES and Blowfish mechanisms are deemed insecure and servers
have removed support for them
- Remove attempts to retry since we only support one mech
- Handle SASL 3.2's new syntax for supported mechs
- Removes need to check for malloc failure
- Removes need for NULL checks on free
- Adds checks for integer overflows
- Removes some extra memset calls
- Removes chance of mixing libc and glib malloc/free
Instead of hardcoding this behavior for @, +, and %, fetch the list of
mode prefixes from the server's state and look for one of those instead.
Closes#977
