This fixes a crash which would happen if you scrolled the script buffer
and then did a search which got fewer search results than the index of
the selected line before the search. E.g. press page down to go to the
second page and then search for `test`.
It turns out that Debian has reverted the commit in Perl that broke the
locale in their 5.38 branch, so it did not have the issue. However, the
workaround we added to fix the locale apparently makes the version
Debian/Ubuntu has crash on perl_destruct. I'm not sure why it makes it
crash, but since it doesn't crash on newer Perl versions, I'm assuming
that it's another bug with the locale handling in that Perl version.
To avoid the crash, make sure to only set the locale if we detect that
it has been broken by Perl. We do this by checking if the value returned
by wcwidth (160) (the first non-ascii printable character) has changed.
If this value is not the same after the call to perl_construct, the
locale has been broken.
I moved the call to Perl_setlocale to right after perl_construct, as the
call to perl_construct is what breaks the locale.
Apparently the issue with the locale being reset with Perl 5.38 can
cause a crash when unloading the scripts on some systems (at least
Ubuntu 24.04). There was a workaround added in commit f4b9cad72, but it
doesn't work to avoid the crash. However if we set LC_ALL instead of
LC_CTYPE the crash doesn't occur.
Fixes#2187
A performance issue was happening when buffers are moved to another position
and when the hotlist contains a lot of buffers: each time a signal
"buffer_moved" is sent, the hotlist is sorted again.
This fix delays the resort of hotlist after all the moves are done using a
timer with a very small delay (one millisecond).
Since WeeChat 4.0.0, the actions are now case sensitive and must be typed as
lower case.
This fixes the help line displayed on top of relay and xfer buffers: letters
for actions are now displayed with lower case instead of upper case.
When the environment variable `RETRY_BUILD` is set to `1`, the file
`debian/rules` is patched to run `dh_auto_build` multiple times, until the
build succeeds.
This is a workaround for an issue with the build in an arm64 chroot, where the
compiler randomly segfaults.
