2020-01-10Trivial changes: whitespace and modes.Dan Cross700-4966/+4647
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>
2020-01-08mk: plan9 style.Dan Cross1-7/+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>
2020-01-07mk: fix out of bounds accessNeven Sajko1-7/+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
2020-01-079term: add a "look" menu item (#299)Fazlul Shahriar3-0/+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
2020-01-02cmd/htmlroff: fix buffer overflow in t2.c getqargNeven Sajko1-1/+1
This is actually from 2016: https://plan9port-review.googlesource.com/c/plan9/+/1590 Change-Id: I6f2a3d71a9dd589eff7ab15b3c1d3997254b3c35
2020-01-02ls: check that pointer is not nil before calling qsortNeven Sajko1-1/+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
2020-01-02acme: do not pass null pointers where disallowedNeven Sajko2-1/+4
The C standards disallow passing null pointers to memmove and memcmp. Change-Id: I1c88c2adbc32a23ef742f206038b8f7c4e0540c7

2020-01-02cb: fix a null pointer dereferenceNeven Sajko1-3/+3
Just added a pair of parentheses. I also ran cb on cb.c to beautify the code. This is actually on Gerrit from 2016: https://plan9port-review.googlesource.com/c/plan9/+/1574 Change-Id: I5e234adba0f95c13d6eecb121bf11bba4bf54566

2019-12-10ed: formatting tweak (remove redundant tab). (#301)Marc Simpson1-1/+1
2019-12-08page: fix pdf prolog for ghostscript >= 9.27 (#296)Fazlul Shahriar2-4/+2
Ghostscript 9.27 removed GS_PDF_ProcSet and pdfdict due to a security issue (see https://security-tracker.debian.org/tracker/CVE-2019-3839). This fix was contributed by @onyxperidot (see #279). Fixes #279
2019-12-08ed: replace magic number (077776, i.e. 32766) with NBLK-1. (#300)Marc Simpson1-1/+1
Temp file size is now declared in an enum; changing it from the default introduces a subtle bug in putline(), which expects it to be 32767. Mask with NBLK-1 instead.
2019-11-14page: fix hang for forward-only postscript filesFazlul Shahriar2-1/+7
Page was hanging because ghostscript never closes the fd from which we're reading BMP data. We close our end of the pipe so that ghostscript will close its end. Tested with ghostscript version 9.50. Fixes #124
2019-10-29plumber: add -f (foreground) option (#288)Jason Felice3-4/+11
In MacOS, services run by launchd must run in the foreground, since launchd manages forking and other resources.
2019-10-29awk: split record into runes for empty FS (#292)Fazlul Shahriar1-4/+9
awk was splitting records into bytes instead of runes for empty FS. For example, this was printing only the first byte of the utf-8 encoding of é: echo é | awk 'BEGIN{FS=""}{print $1}' The change just copies how the `split` function handles runes. Originally reported by kris on twitter: https://twitter.com/p9luv/status/1180436083433201665
2019-09-19hoc: don't nest calls to follow() when lexing ++/+= and --/-= (#287)deepcube1-2/+2
The code had a nested use of the follow() function that could cause +=+ and -=- to register as ++ and --. The first follow() to execute could consume a character and match and then the second follow() could consume another character and match. For example i-=-10 would result in a syntax error and i-=- would decrement i.
2019-09-19upas/nfs: fix null date when message is sent to plumber (#263)telephil1-1/+1
When fetching, messages are sent to plumber as soon as the ENVELOPE part is read. The date field of the message is sent when the INTERNALDATE part is read and there is no guarantee that this will be read before the ENVELOPE. This bug can be observed when using faces(1) which will retrieve messages with a null date and then always display a 'Jan 1' date instead of the correct one. The fix is to simply send the message to plumber after having read all parts, thus ensuring the message is complete.
2019-09-19plumber: fix EOF detection on writes to rules file (#257)Fazlul Shahriar1-3/+3
Instead of checking Fcall.data==nil, check Fcall.count==0. The former check always fails after `gcc -O2` optimizations (gcc version 8.3.0). Also fix an out-of-bound read detected by valgrind: ``` ==31162== Invalid read of size 1 ==31162== at 0x11005E: morerules (rules.c:739) ==31162== by 0x110254: writerules (rules.c:775) ==31162== by 0x10D2FE: fsyswrite (fsys.c:848) ==31162== by 0x10C304: fsysproc (fsys.c:248) ==31162== by 0x112E8C: threadstart (thread.c:96) ==31162== by 0x4A682BF: ???

2019-09-19auxstats: replace /proc ACPI calls with /sys ones (#245)Zach Scott1-22/+8
According to <https://askubuntu.com/a/309146>, use of `/proc/acpi` to get battery usage is deprecated. This commit replaces the two files from this API with the single file `/sys/class/power_supply/BAT0/capacity`, simultaneously removing the need to calculate battery percentage.
2019-06-19devdraw: cocoa metal screen adds a delayed update (#270)Xiao-Yong1-0/+7
The immediate display of the screen sometimes miss the update from the CPU side memory. No obvious synchronization mechanism is available. In order to make sure the screen updates properly, we set needsDisplay again after 16ms delay to ensure a second screen update.
2019-06-11devdraw: handle windowDidResize on macOS (#212)Pocket78781-1/+7
This supports non-live window resize.
2019-06-10acme: accept expanded URLs in lookRuss Cox1-9/+39
Just as look expands a click in /etc/passwd to the full name (provided that file exists), it now expands a click in https://9fans.net/ to the full URL (provided the prefix is http:// or https://). Probably more adjustment is needed.
2019-05-17acme: delete trailing spaces during Put in autoindent modeRuss Cox1-41/+64
Autoident mode is the leading cause of trailing spaces on lines. Remove them during Put to make various picky tools happier. The changes during Put are added as a separate entry to the file history, so that the first Undo after Put restores the spaces.
2019-05-17devdraw: cocoa metal screen updates (#215)Xiao-Yong1-63/+27
* devdraw: cocoa metal screen uses a dirty hack to make everything smooth * devdraw: cocoa metal screen uses a layer to make fullscreen applications behave * devdraw: macOS cocoa metal fix resizeimg without img * devdraw: macOS cocoa metal uses blit instead of render We directly use the blit command encoder to copy texture to the framebuffer. We no longer need to compile the metal shader every time the application starts just for rendering a flat 2D surface. * travis: add osx images covering 10.13 and 10.14
2019-04-19acme: do not trim spaces during PutRuss Cox1-4/+8
The commit that introduced this was pushed accidentally. It is not a good idea to do this. (It breaks programs that think that a clean window means the body matches the on-disk file.)
2019-04-05samterm: stop ignoring all keys >= KcmdPocket78781-2/+3
2019-04-05devdraw: stop redirecting ^H in cocoa-metal (#209)Xiao-Yong1-1/+0
2019-04-05libdraw,devdraw: fix compatibility with old 16x16 cursor protocol (#217)Fazlul Shahriar2-0/+9
Some libraries that depend on devdraw don't know about 32x32 cursor -- mainly 9fans.net/go/draw.

2019-04-05devdraw: fix cocoa metal _flushmemscreen for invalid rectangles (#240)Xiao-Yong1-0/+4
It is possible to receive multiple screen resize events, and resizeimg would be called for different sizes, before _flushmemscreen actually gets called with rectangle sizes different from the most recent resizeimg call. The size mismatch would trigger illegal memory access inside _flushmemscreen. This commit protects _flushmemscreen by returning early if the requested rectangle is outside of the current texture rectangle.
2019-04-05devdraw: respond to windowDidBecomeKey on darwin (#239)Jacob Vosmaer1-0/+5
Fixes bug where devdraw does not "notice" mouse position after task switch. Fixes https://github.com/9fans/plan9port/issues/232.
2019-02-25page: handle EPS without showpageRuss Cox2-1/+6
2019-02-01rio: delete ancient Imakefile (use mk instead)Russ Cox1-27/+0
Fixes #235.
2019-02-01acme: drop trailing spaces during Put of auto-indent windowRuss Cox1-3/+38
Auto-indent mode leaves trailing spaces on blank lines as you type past them, so silently elide them from the window content as it gets written back to disk. Another option would be to remove them from the window entirely during Put, but they're actually nice to have while editing, and to date Put has never modified the window content.
2018-11-16libdraw: redo default font construction to be hidpi-safeRuss Cox2-4/+0
If $font is not set, the default font is constructed from font data linked into every libdraw binary. That process was different from the usual openfont code, and so it was not hidpi-aware, resulting in very tiny fonts out of the box on hidpi systems, until users set $font. Fix this by using openfont to construct the default font, by recognizing the name *default* when looking for font and subfont file contents. Then all the hidpi scaling applies automatically. As a side effect, the concept of a 'default subfont' is gone, as are display->defaultsubfont, getdefont, and memgetdefont.

2018-11-15paint: add drawing program from 9front (#112)Tobias Heinicke3-0/+1128
Paint first appeared in 9front. The 9front license is reproduced in the related source files - the original repository is located at https://code.9front.org/hg/plan9front.
2018-11-15rio: make 'mk all' explain why it does nothing on non-x11 systemsRuss Cox1-2/+4
Fixes #98.
2018-11-15devdraw: remove os x 10.5 compatibility codeJacob Vosmaer4-1790/+2
2018-11-15acme: add 32x32 boxcursorRuss Cox4-2/+71
The only difference from the upscaled 16x16 is a one-pixel adjustment in the offset position, but this at least exercises setcursor2.
2018-11-15devdraw: add Cursor2 support on macOS 10.14 MojaveRuss Cox8-45/+113
This replaces the pixel-art scaling algorithm used for upscaling before. The results were not crisp enough to serve as everyday cursors.

2018-11-15devdraw: rewrite the Cocoa screen using MetalXiao-Yong Jin8-21/+1307
Add a new macOS cocoa screen, cocoa-screen-metal.m. Rewrite the macOS cocoa drawing code to use the builtin runloop, and use Metal to push pixels with CAMetalLayer. Remove all of the deprecated code, and simplify some of the logic. Modify mkwsysrules.sh such that the new code is used only when the system version is equal or higher than 10.14. Allow touch events to simulate mouse clicks: three finger tap for the middle mouse button; four finger tap for the 2-1 chord. Support Tresize. Scale 16x16 Cursor up to 32x32 with an EPX algorithm. Support macOS input sources including the basic dead keys and the advanced CJK input methods. Increase the communication buffers in cocoa-srv.c to allow more input, especially for long sentences prepared by the macOS input souces.
2018-11-14upas/smtp: fix TLS connections (#163)Zach Scott2-0/+49
Both `upas/nfs` and `upas/smtp` call the currently broken `tlsClient()` from libsec. This commit copies a fix from upas/nfs into upas/smtp. In `imapdial()`, upas/nfs replaces a process call for tlsClient with `stunnel3` when not on Plan 9. upas/smtp calls tlsClient directly as a function, so imapdial was copied into mxdial.c as `smtpdial()`, and tlsClient+dial replaced with a call to smtpdial.
2018-11-14devdraw: set displaydpi on devdraw x11 attach (#178)Gabriel Díaz1-2/+7
See https://plan9port-review.googlesource.com/c/plan9/+/1470 for discussion of the approach, especially Michael Stapleberg's comment: Note that chromium, firefox and others have tried this and then switched to using the Xft.dpi X resource, see e.g. https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ui/libgtk2ui/gtk2_ui.cc and especially http://sources.debian.net/src/gnome-settings-daemon/3.18.2-1/plugins/xsettings/gsd-xsettings-manager.c/?hl=824#L80 for some anecdata about why this approach doesn’t work out. The Xft.dpi resource is being set accurately by desktop environments (GNOME, KDE, …) and can easily be changed by users of niche window managers by editing ~/.Xresources. I suggest we check only Xft.dpi, without considering the DPI environment variable or the monitor width/height.
