* acme: fix crash in X |cat with multiple windowsRuss Cox2020-01-131-5/+24
| | | | | | | Fixes #9. Fixes #219. Fixes #222. Fixes #330.
* vac, unvac: allow 128MB cache size, up from 4MBRuss Cox2020-01-132-2/+2
| | | | | | When a directory has lots of children, vac crashes because it runs out of cache. Fixes #266.
* 9pfuse: do not fswalk("..")Russ Cox2020-01-131-12/+5
| | | | | | | f is open, so walk will fail. The comments say we only need one directory anyway. Fixes #277.
* libthread: fix nbrecvul, recvul to match man page, Plan 9Russ Cox2020-01-131-2/+2
| | | | | | | They return 0 on failure, not -1. Bug introduced in my original libthread-for-Unix code. Fixes #230.
* cmd/9pfuse: ignore FMODE_EXEC open flagNicola Girardi2020-01-131-2/+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.
* clock: import from plan 9Russ Cox2020-01-131-0/+104
| | | | Fixes #250.
* lib9: rm unused _p9translate.cRuss Cox2020-01-131-46/+0
| | | | Fixes #238.
* devdraw: AUTOFRAMEWORK CoreFoundation on macOSRuss Cox2020-01-131-0/+1
| | | | Fixes #273.
* devdraw: x11 working againRuss Cox2020-01-1314-2340/+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.
* devdraw: multiclient modeRuss Cox2020-01-133-42/+115
|
* cmapcube: don't crash on initdraw failureRuss Cox2020-01-131-1/+2
|
* libdraw: connect to devdraw via $wsysid when setRuss Cox2020-01-132-1/+79
|
* devdraw: more cleanup, clearer lockingRuss Cox2020-01-138-313/+329
|
* devdraw: refactor, clean up mac screenRuss Cox2020-01-137-505/+492
| | | | | Also turn mac-srv.c into a generic srv.c, so we can remove the duplication with x11-srv.c.
* devdraw: move per-window globals in mac-screen.m into ClientRuss Cox2020-01-133-62/+81
|
* devdraw: move Client into devdraw.h and move global state inRuss Cox2020-01-1310-464/+470
|
* devdraw: use consistent mac-* prefix on macOS filesRuss Cox2020-01-1312-200/+6
| | | | We were using osx- and cocoa- but it's not even OS X anymore.
* devdraw: can use libthread directly now on macOSRuss Cox2020-01-135-79/+13
|
* devdraw: simplify mac file namesRuss Cox2020-01-134-98/+5
| | | | | | Now that we only have Metal, we can drop the -metal. Also now that Carbon is gone we can drop the macargv.c, and then the -objc from object file names.
* devdraw: drop pre-metal macOS supportRuss Cox2020-01-133-1688/+5
| | | | | | | We didn't start using Metal until macOS 10.14, but it was available on 10.13, which is currently the oldest Apple-supported version of macOS. Simplify by deleting the old code.
* devdraw: update drawclient test program to run againRuss Cox2020-01-132-9/+8
|
* cmd/yacc: correctly detect end of file in gettokNeven Sajko2020-01-131-0/+2
| | | | | | This prevents an infinite loop. Change-Id: I7eda6b9d032ca0daeb24b555954330d07f35c78b
* cmd/yacc: check that arg is safe to pass to <ctype.h> isX functionsNeven Sajko2020-01-131-5/+14
| | | | | | | The functions from <ctype.h> require that their argument be representable as an unsigned char, anything else is an error. Change-Id: I9dafc49c431b7a2550b041603f27bac3c0010eea
* cmd/yacc: check for EOF in string constant in cpyactNeven Sajko2020-01-131-1/+1
| | | | Change-Id: I3b41ab3f181080bcff89201d30f0bdf8aa20d55c
* cmd/yacc: do not create an out of bounds pointerNeven Sajko2020-01-131-1/+2
| | | | | | | | | An out of bounds pointer/array index being created is an error in standard C. Updates #313 Change-Id: I7108fcde1a8e03017e9ab852adb737940489c827
* lib9/fmt: avoid racy access to installed fmt formatsRuss Cox2020-01-134-22/+55
|
* lib9: fix memory leak in dial of regular file (#284)jvd232020-01-131-1/+3
|
* fontsrv: allow x11 hinting and disable autohint only (#254)Xiao-Yong2020-01-131-1/+1
| | | | | Some truetype fonts have good manual hinting. Ignoring hinting makes the font render badly on low resolution screens. This commit only disables the freetype autohinter, and allows hinting.
* Make venti's doc more accurateEdouard Klein2020-01-131-1/+1
|
* cmd/venti/srv: split memory allocation callNeven Sajko2020-01-131-2/+2
| | | | | | | | | | | This splits a certain vtmallocz call in mkihash into two vtmallocz calls. The first issue this fixes is that the C aliasing rules were not respected in the code before this commit. The other thing is that this enables better memory alignment guarantees. Updates #313 Change-Id: Ia4f3e0fc85facc778193f5e977d4f99a1a9abd23
* libdraw: fix "mk"Russ Cox2020-01-121-2/+1
| | | | Should default to building the library, not getsubfont.o.
* libthread: run first thread in proc on system stackRuss Cox2020-01-123-17/+47
| | | | | | | For pthread systems that are fussy about which stack is used, this makes sure that threadmain runs on a system stack. If you only use proccreate (never threadcreate), all threads run on system stacks.
* lib9: make a p9frexp function wrapping system frexpRuss Cox2020-01-122-0/+10
| | | | | | Under certain conditions it looks like frexp gets #defined to something else on macOS during system headers, which then breaks the declaration in libc.h.
* all: fix or silence various gcc warningsRuss Cox2020-01-1216-22/+23
| | | | | As usual, gcc finds some real problems but also reports a ton of noise. Fix the problems and quiet the noise.
* Trivial changes: whitespace and modes.Dan Cross2020-01-101021-6193/+5688
| | | | | | | | | Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
* src: mv ../buildEnvironmentVariables mkhdrRuss Cox2020-01-092-1/+23
| | | | | Also note that the file must be valid shell and mk input. For #321.
* mkfile, mkmk.sh: update for new asm-free getcallerpcRuss Cox2020-01-092-3/+3
|
* lib9: add getcallerpc.c (fixes build)Russ Cox2020-01-081-0/+13
|
* libhtml: plug a memory leak in addtextNeven Sajko2020-01-081-0/+3
| | | | Change-Id: I9b8a4430e7d26008ba9508095f8eb4b124a93b9b
* libhtml: plug quite a few memory leaksNeven Sajko2020-01-082-4/+13
| | | | Change-Id: I45bd62a590373669e90183cc2b2ee56570c007f5
* mk: plan9 style.Dan Cross2020-01-081-7/+8
| | | | | | | | In general, no space after `if` etc, and no braces for a single statement inside of a loop or conditional. Signed-off-by: Dan Cross <cross@gajendra.net>
* mk: fix out of bounds accessNeven Sajko2020-01-071-7/+21
| | | | | | | | | A loop is added for each structure field instead of accessing the other fields through the first one in one loop. Updates #313 Change-Id: I0e27e15feacb77391bc1decee7cf720d64d14586
* lib9, libndb: exclude terminating null from strncpy boundNeven Sajko2020-01-072-2/+2
| | | | | | | GCC pointed this out with some "warning: ‘strncpy’ specified bound NUM equals destination size [-Wstringop-truncation]" warnings. Change-Id: Id8408b165f6e4ae82c96a77599d89f658d979b32
* lib9: remove getcallerpc implementationsRuss Cox2020-01-078-55/+1
| | | | | | | | These make no sense and are not really needed at all. Add a best-effort attempt to get at the gcc/clang macro in lib9.h, but if it fails, no big deal. Fixes #324.
* libmach: plug another memory leakNeven Sajko2020-01-071-0/+2
| | | | Change-Id: Ia5c888db1f0ded2aa92238d994239e46bf52667a
* libmach: plug memory leakNeven Sajko2020-01-071-1/+4
| | | | Change-Id: I08cb7227c071c7fc2e30f43e07bcf599fc1d174a
* 9term: add a "look" menu item (#299)Fazlul Shahriar2020-01-073-0/+32
| | | | | | | Add a menu item which functions similar to acme's `Look` command. This is copied from 9front. See: https://code.9front.org/hg/plan9front/rev/1f1596dbca51 https://code.9front.org/hg/plan9front/rev/d2de1d2f7b48
* all: sync and dedup the creation of the SYSNAME and OBJTYPE env vars (#321)Neven Sajko2020-01-071-19/+1
| | | | | | | | | | | This should prevent the issues of dist/buildmk and src/mkhdr getting out of synchronization yet again. I also add a rule for arm64 to the OBJTYPE sed command. Fixes #243 Fixes #320 Change-Id: I60f69a1f32b5ed5ae5ac8a1659c38e29debed005
* cmd/htmlroff: fix buffer overflow in t2.c getqargNeven Sajko2020-01-021-1/+1
| | | | | | | This is actually from 2016: https://plan9port-review.googlesource.com/c/plan9/+/1590 Change-Id: I6f2a3d71a9dd589eff7ab15b3c1d3997254b3c35
* ls: check that pointer is not nil before calling qsortNeven Sajko2020-01-021-1/+1
| | | | | | | Passing a null pointer to qsort is an error in C (GCC and Clang agree with the standards there, so this is no joke). Change-Id: Ia2b015793a75ea4e85ae8f47da6beead9c4290e6
