2020-05-29fontsrv: handle non-BMP runes on X11Russ Cox4-43/+44

2020-05-18man: update man pages to say $HOME when accurateRuss Cox4-33/+37
Fixes #386.
2020-05-18devdraw, libdraw: handle keyboard runes > U+FFFFRuss Cox7-8/+34
Runes in Plan 9 were limited to the 16-bit BMP when I drew up the RPC protocol between graphical programs and devdraw a long time ago. Now that they can be 32-bit, use a 32-bit wire encoding too. A new message number to avoid problems with other clients (like 9fans.net/go). Add keyboard shortcut alt : , for U+1F602, face with tears of joy, to test that it all works.

2020-05-17libthread: handle spurious _procsleep wakeups, fix $LIBTHREAD handlingRuss Cox2-6/+26
2020-05-17libthread: add pthreadperthread mode and use under ASANRuss Cox4-18/+120
ASAN can't deal with the coroutine stacks. In theory we can call into ASAN runtime to let it know about them, but ASAN still has problems with fork or exit happening from a non-system stack. Bypass all possible problems by just having a full OS thread for each libthread thread. The threads are still cooperatively scheduled within a proc (in thos mode, a group of OS threads). Setting the environment variable LIBTHREAD=pthreadperthread will enable the pthreadperthread mode, as will building with CC9FLAGS='-fsanitize=address' in $PLAN9/config. This solution is much more general than ASAN - for example if you are trying to find all the thread stacks in a reproducible crash you can use pthreadperthread mode with any debugger that knows only about OS threads.
2020-05-17INSTALL: build mk all the timeRuss Cox1-4/+3
If mk gets into a bad state, it's not obvious that you can remove the binary to force the rebuild. Also, not rebuilding means that bugs in mkmk.sh are not noticed. Just rebuild from scratch every time. It doesn't take too long compared to the rest of INSTALL.
2020-05-179c, 9l: accept CC9FLAGS from configRuss Cox3-18/+39
Also, if CC9FLAGS includes -fsanitize=address (ASAN), predefine PLAN9PORT_ASAN for use by programs that need to know (mainly libthread). The 9c script used to have a variable called ngflags, which was ccflags except -g (ng stood for "no g"), but nothing needs it split out anymore, so simplify to just ccflags.
2020-05-17mk: replace overlapping strcpy with memmoveRuss Cox1-1/+2
Found by ASAN.
2020-05-17lib9: use opendir/readdir to read directoriesRuss Cox2-186/+187
getdirentries(2) has been deprecated on macOS since 10.5 (ten releases ago). Using it requires disabling 64-bit inodes, but that in turn makes binaries incompatible with some dynamic libraries, most notably ASAN. At some point getdirentries(2) will actually be removed. For both these reasons, switch to opendir/readdir. A little clunky since we have to keep the DIR* hidden away to preserve the int fd interfaces, but it lets us remove a bunch of OS-specific code too.
2020-05-17lib9: move seek into open.cRuss Cox4-12/+7
More preparation for opendir.
2020-05-17lib9: add closeRuss Cox2-1/+10

2020-05-07fmt: disable use of stdatomic on AIX XL C and old GCCRuss Cox1-0/+21

2020-05-059term.app: respect user-set shell instead of forcing bashRuss Cox1-2/+22

2020-05-05rc: clean up parser levels, disallow free carats on listsRuss Cox4-31/+37
2020-05-04rc: allow unquoted = in command argumentsRuss Cox3-11/+28
dd fans rejoice! Also helps with commands like go test -run=x.
2020-05-04rc: move free carat handling into parserRuss Cox5-97/+106
This fixes at least one shell script (printfont) that expected 'x'`{y}'z' to mean 'x'^`{y}^'z' as it now does. Before it meant: 'x'^`{y} 'z' One surprise is that adjacent lists get a free carat: (x y z)(1 2 3) is (x1 y2 z3) This doesn't affect any rc script in Plan 9 or plan9port.
2020-05-04rc: move newline handling into parserRuss Cox6-24/+67
2020-05-04rc: add recursive descent parserRuss Cox13-9/+730
The old yacc-based parser is available with the -Y flag, which will probably be removed at some point. The new -D flag dumps a parse tree of the input, without executing it. This allows comparing the output of rc -D and rc -DY on different scripts to see that the two parsers behave the same. The rc paper ends by saying: It is remarkable that in the four most recent editions of the UNIX system programmer’s manual the Bourne shell grammar described in the manual page does not admit the command who|wc. This is surely an oversight, but it suggests something darker: nobody really knows what the Bourne shell’s grammar is. Even examination of the source code is little help. The parser is implemented by recursive descent, but the routines corresponding to the syntactic categories all have a flag argument that subtly changes their operation depending on the context. Rc’s parser is implemented using yacc, so I can say precisely what the grammar is. The new recursive descent parser here has no such flags. It is a straightforward translation of the yacc. The new parser will make it easier to handle free carats in more generality as well as potentially allow the use of unquoted = as a word character. Going through this exercise has highlighted a few dark corners here as well. For example, I was surprised to find that x >f | y >f x | y are different commands (the latter redirects y's output). It is similarly surprising that a=b x | y sets a during the execution of y. It is also a bit counter-intuitive x | y | z x | if(c) y | z are not both 3-phase pipelines. These are certainly not things we should change, but they are not entirely obvious from the man page description, undercutting the quoted claim a bit. On the other hand, who | wc is clearly accepted by the grammar in the manual page, and the new parser still handles that test case.
2020-04-309c: added explicit -fcommon to gcc defaults.sean1-0/+1
Version 10 of gcc enforces -fno-common which breaks a lot of things. This fix reverts to the pre-10 behaviour. The real fix is to clean up stray redefinitions which should be declarations.
2020-03-30acme: scale window bodies on resize, not including tag spaceRuss Cox1-3/+5
This avoids reopening collapsed windows after a large vertical resize.
