Just added a pair of parentheses. I also ran cb on cb.c to beautify the
code.
This is actually on Gerrit from 2016:

Change-Id: I5e234adba0f95c13d6eecb121bf11bba4bf54566
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.
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
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.

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.
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.
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:

Fixes#256
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.
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.
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.
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.
* 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
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.)
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.
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.
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.

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.
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.
This makes fontsrv use the PostScript font names on X11.
The PostScript font names contains only alphanumeric and
hyphens. This allows us to use the Font command in acme.
It also matches the font names used by fontsrv on macOS,
which has been using PostScript font names.
