rfc_casecmp was broken because reaching terminator for str1 was used as
a terminal condition and str2 may be shorter than str1, resulting in an
oob read condition for str2.
rfc_ncasecmp was broken because it checked if n characters were checked
or if BOTH pointers reached their terminator, however the strings may
be different lengths and also less than n characters in length, meaning
that they don't both reach their terminators at the same time,
resulting in an oob read condition.
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.
Quick rundown of benefits:
- Much faster:
- Autotools (with autogen): 22 seconds
- Meson: 7 seconds
- Meson (with ccache): 2 seconds
- Simpler:
- ~1000 lines smaller
- Single simple language
- Potentially better Windows (Visual Studio) support
What is not done:
- Complete Windows support
- OSX support (easy)
Closes#2013Closes#1937Closes#1803
This could possibly cause a crash.
On a related note exec_data() and exec_handle_colors() could probably
use a pass cleaning up to ensure they "do the right thing".
- 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
Part 2 of 03767ee0f9
So how the colors work should be pretty straight forward:
- A message comes in and is handled, this sets the state flags:
nick_said, msg_said, new_data. These map to tab colors.
- This state is reset under one of these conditions:
- It is commited to the UI when actually printed on unfocused tab
- Event is interupted by a plugin hook
- The tab focus is changed
At least try the untranslated one...
Also while at it don't present a ton of dialogs to the user
about this failure, they wouldn't even know what to do with
that information.
