Certain XkbOptions in X11 would change keysyms for modifier keys
between the key press and key release.
For example, under the XkbOptions "grp:shifts_toggle", though shift
keys remain Shift_L/R when pressed, they become ISO_Group_Next/Prev
when released.
This behavior makes devdraw unable to detect the release event
correctly and as a result mouse button 1 click always interpreted
as button 3 event after a shift key is used.
When the 9P connection is closed, reads on the connection will keep
returning 0. So, fossil ends up looping forever, trying to read a 9P
message, consuming 100% CPU. The fix interprets 0 bytes read as EOF.
Reproduce by killing the 9pserve process serving the fossil service, or
by listening on tcp and using 9p(1).
For fonts with subfiles that go beyond the xffff range, the font file size
calculation is incorrect, since lines beyond that range have additional
characters. This patch pads all of the ranges and subfont names with
leading zeros in order to keep them all lines the same length and fixes the
font file length calculation.
It's sometimes useful to know whether there's been editing activity
in a window. This PR adds that information to the ctl file.

For cross-compiling plan9 from Unix, provide a way
to force `mk` to use `rc` instead of `sh` without
setting `MKSHELL` in individual `mkfile`s.
If the environment variable `FORCERCFORMK` is set,
`mk` will default to using `rc`, not `sh`.

On March 23, 2021, Nokia transferred the copyrights in the Plan 9 software
to the Plan 9 Foundation, which relicensed them under the MIT license.
This commit updates the Plan 9 from User Space license to reflect the
new base license. The vast majority of the contributions beyond the
base Plan 9 set were by me, many of them explicitly under an MIT license.
Those are all under the new MIT license now as well.
The port of mk to Unix was taken from Inferno via Vita Nuova and had
been made available under GPL, but Vita Nuova has relicensed Inferno
under the MIT license as well, to match the new Plan 9 license.
Michael Teichgraber contributed src/lib9/zoneinfo.c explicitly under
the Lucent Public License but has agreed to change the contribution
to the MIT license now used in the rest of the distribution.
There remain a few exceptions, most notably fonts.
See the root LICENSE file for full details.
The only mention of the Lucent Public License in the whole tree now
is in the LICENSE file, explaining the history.
MacFUSE 4 removes support for passing device fd to the mount command. Adds
support for the receiving the fd over a socket instead, and updates command paths
and filesystem name.
Use bio(3) to read at most one line of input per iteration, even
if there is more than one line available in the input buffer. This
makes it easier to interact with line-oriented ctl files like that of
factotum(4) from shell scripts, without the need to control when
and how much data is flushed to a pipe.
Usually r->nused < r->nalloc and the read is in bounds.
But it could in theory be right on the line and reading
past the end of the allocation.
Make it safe but preserve as much of the old semantics
as possible. This use of rterm appears to be only for
optimization purposes so the result does not matter
for correctness.
For whatever reason all three of these programs
contain switches like:
switch(x) {
case 1:
if(cond)
case 2:
f();
}
Like Duff's device, this is legal C but more obscure
than it really needs to be.
This commit assumes those are intended as written
and simply writes them more clearly. I did consider
that maybe they are mistakes, but in the case of sam/regexp.c,
my rewrite in this commit matches the acme/regx.c that
has been in plan9port since I added acme in 2003.
(I didn't bother to dig up the old Plan 9 releases.)
Assuming acme/regx.c has been correct for the past
two decades, this commit should be correct too.
Programs that want to background themselves now need
to define threadmaybackground returning 1.
This avoids a confusing (to people and debuggers)
extra parent process for all the threaded programs
that will never want to background themselves.
Drawing as white on black to produce a mask only works if
the white on black is the inversion of black on white.
Emoji that force use of specific colors don't respect that.
Draw black on white and invert to mask separately.
This fixes https://github.com/9fans/plan9port/issues/436
This doesn't necessarily address the underlying issue: calling p9create with
mode = OREAD should probably be allowed, but currently doesn't work on
OpenBSD.
Unclear why it is here (wkj added it long ago).
It has never been installed into $PLAN9/bin,
so it's doubtful that anyone has ever used it.
Arnold Robbins has an alternate version at

Fixes#421.
List mode was constrained to the BMP. This change introduces
the following new list mode convention, using Go string literal syntax:
Non-printing ASCII characters display as \xhh.
Non-ASCII characters in the BMP display as \uhhhh.
Characters beyond the BMP display as \Uhhhhhhhh.
