2020-01-19libthread: remove Linux 2.4 codeRuss Cox7-513/+462
Linux.c was for Linux 2.4 and is no longer used directly, only indirectly because NetBSD.c was a 1-line file #including Linux.c. So mv Linux.c NetBSD.c. Also rm Linux-*-asm.s which was for Linux 2.4 as well.
2020-01-19libthread: rm unused sparc-ucontext.hRuss Cox2-37/+0
More dead code.
2020-01-19libthread: rm Darwin pre-11.0.0 supportRuss Cox5-192/+0
Darwin 11.0.0 was Mac OS X 10.7.0 aka Lion. The previous version was Snow Leopard, which has been unsupported by Apple since February 2014.
2020-01-19libthread: rm FreeBSD 4 codeRuss Cox6-500/+52
Pretty sure FreeBSD 4 is gone now. :-)
2020-01-19libthread: rm OpenBSD.cRuss Cox1-145/+0
This should have been deleted in 20f5692b (2012-07-14), which removed the mkfile and sysofiles.sh references to it.
2020-01-19libthread: rm unused ARM (get|set)mcontext (#354)Neven Sajko1-43/+0
They were just a duplicate of my(get|set)mcontext from the other assembly file, and unused from threadimpl.h. Change-Id: Id8003e5177ed9d37a7f0210037acbe55bbf7f708
2020-01-16devdraw: abort alt sequence on window change on macOSRuss Cox1-0/+4
Fixes #3.
2020-01-16libthread: NetBSD supports pthreads, remove ancient systems in sysofiles.shDan Cross1-8/+1
Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-16malloc: remove lockingDan Cross3-41/+3
The issue manifests in fork: POSIX fork mandates that a fork'd process is created with a single thread. If a multithreaded program forks, and some thread was in malloc() when the fork() happened, then in the child the lock will be held but there will be no thread to release it. We assume the system malloc() must already know how to deal with this and is thread-safe, but it won't know about our custom spinlock. Judging that this is no longer necessary (the lock code was added 15 years ago) we remove it. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-16lib9: putenv wraps POSIX setenv, not legacy putenvDan Cross1-7/+1
POSIX setenv does everything that p9putenv's body, so just delegate to that. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-15devdraw: avoid deadlock in x11 resizeRuss Cox2-0/+3
Fixes #347.
2020-01-15cmd/rio: xshove: set geometry by window idNicola Girardi1-1/+6
2020-01-15libmach: Fix type errors in FreeBSD.cDan Cross1-4/+4
The ptrace handlers wanted to take u64int arguments, not ulong. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-15devdraw: set windowrect correctly on x11 if window gets unexpected sizeRuss Cox1-2/+2
Fixes #54.
2020-01-15devdraw: actually send resize event on resizeRuss Cox1-0/+7
Fixes #340. Fixes #343.
2020-01-15factotum: update for new nbrecvul return valueRuss Cox1-2/+30
Unclear whether the old semantics were the right ones, but at least this preserves what they've been for the past however many years.
2020-01-15compress: import Plan9 compresssean2-0/+1289
Add #define USED(x)... boilerplate compress: import Plan9 manpage.
2020-01-15winwatch: Plan 9-ify.Dan Cross1-426/+412
This is new code, and custom to plan9port. Make it conform more closely to plan9 style. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-15clock: Remove unused static variable in clock.cDan Cross1-2/+0
`struct Tm tms` was set but never referenced; noticed in a compiler warning. Remove it. Signed-off-by: Dan Cross <cross@gajendra.net>
2020-01-15winwatch: port based Plan 9 winwatchmarkvanatten2-1/+539
Port of Plan 9's winwatch(1).
2020-01-159pfuse: update errortabOleg Nemanov1-0/+2
2020-01-14venti/buildindex: fix hang on large indexesRuss Cox1-1/+1
Fixes #93.
2020-01-14devdraw: notify window resize promptly on x11Russ Cox5-13/+28
Fixes #339.
2020-01-14libdraw: send hangup to process when window is lostRuss Cox1-1/+5
This matches the Plan 9 behavior a bit better. Fixes #30.
2020-01-14lib9: make formatting lock-free againRuss Cox4-124/+83
First use of <stdatomic.h>. We will see if any supported systems don't have it yet. (C11 was so last decade.) Fixes #338.
2020-01-14acme: save/restore multiline tags in Dump/LoadRuss Cox1-4/+16
The dump substitutes each \n in a multiline tag with a 0xff byte. Since it is not valid UTF it cannot occur in an ordinary dump file. Old acmes will just read it in as an error rune. Fixes #135. Fixes #153.
2020-01-14tar: remove /bin/ when invoking compressorsphonologus1-6/+1
2020-01-14libthread: use mmap to allocate OpenBSD stacksRuss Cox6-8/+61
Should fix faults on OpenBSD. Fixes #218. Fixes #226.
2020-01-14libdraw: use proper pipe for default font dataRuss Cox1-6/+16
May fix a deadlock / missing font on OpenBSD. Fixes #308.
2020-01-14devdraw: do not force-hide menu and dock during full screen on macRuss Cox1-3/+15
This hides the menu on dock on all screens which is more than we want. The code was added to fix a problem with Catalina that I can no longer reproduce, so I guess it works now. Fixes #336.
2020-01-13devdraw: hide dock in full screen modeRuss Cox1-0/+13
Unfortunately this hides the dock even if it is on a different screen. We need to figure out how to tell. But this is more usable than not. Probably.
2020-01-13devdraw: correctly hide Mac menu bar (#335)Xiao-Yong1-9/+9
`window:willUseFullScreenPresentationOptions:` is an instance method of the protocol `NSWindowDelegate`.
2020-01-13libthread: fix fault in teardown of procRuss Cox2-1/+2
Fixes #332.
2020-01-13acme: fix buffer overflow introduced in parsetag refactorRuss Cox3-8/+8
2020-01-13acme: fix movetodel for spaces in file namesRuss Cox1-11/+8
2020-01-13acme: allow spaces in window namesRuss Cox2-5/+20
There are many things we could do to make this work. an environment variable to control the character. Another option would be to use U+00A0 (non-breaking space), which renders the same as space. This change avoids changing the separator character and instead assumes that if the left side of the tag already ends in " Del Snarf |" then what comes before that is the file name. Acme already aggressively preserves the "Del Snarf |", so this should work decently well as a stop-gap. We can always try something else later. Fixes #26. Fixes #104. Fixes #329.
2020-01-13mk: fix hash function (#315)Neven Sajko1-7/+3
Avoid signed integer overflow using ulong instead of long h.
2020-01-13acme: one more place to use parsetagRuss Cox1-5/+1
2020-01-13acme: factor out tag parsing codeRuss Cox3-21/+28
2020-01-13lib9: do not fetch disk size for character devicesRuss Cox1-1/+1
Real disk devices should be block devices anyway. One user reported the disksize check causing a system reboot during vac of a tree with an "interesting" device. Fixes #103.
2020-01-13mk: treat X= as empty list in rc shellRuss Cox1-6/+12
This brings mk's behavior when using rc in line with Plan 9's. The existing code is for Unix environment data structures but also was assuming Unix shell semantics where empty and missing variables are mostly equivalent. The Plan 9 code (/sys/src/cmd/mk/plan9.c in the distribution) explicitly removes /env/name (creating an empty list) when the value is missing or an empty string. Fixes #255.
2020-01-13acme: fix crash in X |cat with multiple windowsRuss Cox1-5/+24
Fixes #9. Fixes #219. Fixes #222. Fixes #330.
2020-01-13vac, unvac: allow 128MB cache size, up from 4MBRuss Cox2-2/+2
When a directory has lots of children, vac crashes because it runs out of cache. Fixes #266.
2020-01-139pfuse: do not fswalk("..")Russ Cox1-12/+5
f is open, so walk will fail. The comments say we only need one directory anyway. Fixes #277.
2020-01-13libthread: fix nbrecvul, recvul to match man page, Plan 9Russ Cox1-2/+2
They return 0 on failure, not -1. Bug introduced in my original libthread-for-Unix code. Fixes #230.
2020-01-13cmd/9pfuse: ignore FMODE_EXEC open flagNicola Girardi1-2/+11
Improved error message in case of unexpected open flags. The message unexpected open flags requested=0100040 unhandled=040 prompted me to clear the FMODE_EXEC flag, although I wonder if I shouldn't have set OEXEC (0x3) instead.
2020-01-13clock: import from plan 9Russ Cox1-0/+104
Fixes #250.
2020-01-13lib9: rm unused _p9translate.cRuss Cox1-46/+0
Fixes #238.
2020-01-13devdraw: AUTOFRAMEWORK CoreFoundation on macOSRuss Cox1-0/+1
Fixes #273.
2020-01-13devdraw: x11 working againRuss Cox14-2340/+1844
Need to think a bit more about locking, but overall it's a working devdraw. Multiclient mode may not be working but nothing is using it yet.
