This takes into account the possibility of multiple peers in
the group using the same nick. The /whois command now lists
all peers associated with the input name, and all commands
that target a peer with a non-unique nick will require the
public key to be used.
The wcswidth() function was silently failing when trying to convert
messages containing a newline to a widechar buffer which resulted
in the message showing up as an empty line. we now fall back
to using strlen to get the width of the string, which might still
cause minor display bugs when the message contains unicode, but is
still better than losing messages entirely.
This fixes a bug where printing a bunch of UTF8 chars with glyphs
that have a size > 1 would make the entire chat window disappear.
It also fixes an issue where said UTF8 chars would be truncated
and generally not display correctly.
This will alert the user when the first six bytes of a new
contact's public key is the same as any other contact in
their list. These 6 bytes are used elsewhere in toxic for
unique identification.
Also did a small refactor regarding the KEY_IDENT_BYTES
define
libbrotli has updated its .pc files since the last sed was written, so
it didn't work anymore, resulting in Toxic build failing. However, the
way they have updated it, it's still broken, so a different sed is
needed.
The Docker detection method doesn't work on cgroup v2 systems, so the
script just keeps erroring out.
There doesn't seem to be a simple way to detect that we are running
inside a Docker container, so it makes sense to drop that check
altogether.
There is no check at all that the types of externs actually match the
type of the definition. This just accidentally was not a problem, but now
the compiler helps a bit in keeping it that way.
