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.

Commit d32deab17bfffa5bffc5fab3e6577558e40888c5 renamed IM to MR but
these man pages were missed.

This fixes the 'run stats from rc; exit rc; stats dies' problem.
It's unclear whether this is the right fix or whether rc should
be starting all its interactive commands in their own process
groups. But at least it does fix stats dying.

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.
|
|
The exit code here is ignored anyway.
|
|
This happens if lldb attaches to rc.

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.

Having two locks in the proc was causing deadlocks.

It is no longer special.

Now that we assume pthreads, the only assembly
left is in libmp and libsec.
We only ever added assembly for 386.
The portable C code is fine for plan9port.

Fixes #376.

Fixes #362.

Now that everything uses pthreads and pthreadperthread,
can delete various conditionals, all the custom context code,
and so on. Also update documents.
Fixes #355.

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.

I added a direct call from thread.c to pthread.c's _threadpthreadstart
in May, and no one has complained about NetBSD being broken.
So probably no one is using this on NetBSD at all.
Make pthread the only option.

This was causing sporadic but frequent crashes at startup
in 9pserve on the new M1 Macs, correctly diagnosing a
use-after-free.

This should make the AIX build finally work.
Fixes #400.

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.

The overloading of IR emits magic \X'...' sequences that turn into HTML manual links.
But not all such IR invocations should be manual links;
those had to be written to avoid the IR macro before.
Worse, the \X'...' ending the IR causes troff to emit only a single space after a period.
Defining a new IM macro for manual references fixes both problems.
Fixes #441.

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.

Fixes #432.
