85bfb0e9eb reduce: use if() to test for exit status of pipeline
The new rc's exit status will be '' for a successfull
pipeline execution instead of '|'.

This is a bit too tightly coupled, so just use if()
statement instead, handling this in a portable way.

4d872079d3 iostats: bind /srv into the namespace, its magic
programs that try to use /srv would choke when running
under iostats, because we intercepted operations on the
special, magic fd passing; we should instead give them
access to the real /srv.

9e79aaceba git/commit: squelch error when run outside repository
when running outside of a repository, we would try to
remove '$msgfile.tmp', but we had never actually set
'$msgfile'.

the error is harmless, but annoying.

47b7dc5ccd acme: fix window and scrollbar display glitches at bottom fringe of column
The following patch fixes acme display glitches at the bottom fringe
of columns when adding/moving/resizing windows.

Here an example of an easy to reproduce case:

• https://invidio.xamh.de/watch?v=iLekQrxycaM

…opening acme and resizing a column to the right is all that is needed.

The functions winresize(…) and textresize(…) are extended with an
additional parameter `fillfringe` to indicate if a window/tag shall
fill a potential fringe area that would otherwise remain white.

The changes have been inspired by the approach taken in plan9port
acme.

369cba5f93 rc: read heredoc when receiving '\n' (thanks Eckard Brauer)
Eckard's test case:

cat <<! | cat
asdf
!

The issue is that we have to continue parsing until we see
the '\n' before consuming the here document.

So we revert to the old approach of having two functions:

heredoc() which remembers if we'v seen a heredoc redirection
and a second readhere() function that reads the doc from
the lexers input and sets Tree.str on thee REDIR node.

70edb7fbae git/fs: remove trailing null bytes from parent file (thanks mcf)
due to the way the size of buf was calculated, the parent
file had one trailing null byte for each parent. also, while
we're here, replace the sprint with seprint, and compute the
size from how much we printed in.

f63d1d3ced git: size cache in bytes, not objects
git used to track cache size in object
count, rather than bytes. This had the
unfortunate effect of making memory use
depend on the size of objects -- repos
with lots of large objects could cause
out of memory deaths.

now, we track sizes in bytes, which should
keep our memory usage flatter.

b90036a062 rc: fix everything
Untangle the lexer and interpreter thread state.

Fix the file and line number error reporting, getting rid of
Xsrcfile instruction, as the whole code block can only come
from a single file, stuff the source file in slot[1] of the
code block instead.

Remove limitations for globber (path element limits)
and be more intelligent about handling globbing by
inserting Xglob instruction only when needed and not
run it over every Xsimple argument list.

Remove fragile ndot magic and make it explicit by adding
the -q flag to . builtin command.

Add -b flag for full compilation.

Make exitnext() smart, so we can speculate thru rcmain and
avoid the fork().

Get rid of all print(2) format functions and use io
instead.

Improve the io library, adding rstr() to handle tokenization,
which allows us to look ahead in the already read buffer
for the terminators, avoiding alot of string copies.

Auto indent pcmd(), to make line number reporting more usefull.

Implement here documents properly, so they can work everywhere.

614f1d6268 rio: allow spaces in working directory path (-cd) when creating a new window via wctl
The initial working directory of a new window may be set by a
`-cd directory` option. However, the `-cd directory` option is
not capable of handling paths with spaces when used via wctl.

To enable paths with spaces the function
/sys/src/cmd/rio/wctl.c:/^parsewctl is extended to handle quoted
directory paths.

Before applying the patch the following will fail to open a new
window by writing to /dev/wctl:

<snip>
 % rio -i window
 % mkdir '/tmp/path with space'
 % echo new -cd '''/tmp/path with space''' window -x rc >> /dev/wctl
 % pwd
 /tmp/path with space
<snap>

The following invocation fails as well:

<snip>
 % window -cd '/tmp/path with space'
 % pwd
 /tmp/path with space
<snap>

After applying the patch the above sequences work as expected,
opening a window running rc with the working directory set to
'/tmp/path with space'.

0f58e47551 exportfs, oexportfs, iostats: make -d log to stderr
exportfs -d logs 9p traffic to /tmp/exportdb.
-f allows writing to a different file.
exportfs silently continues if it doesn't have
permissions to create or write to /tmp/exportdb.
These are poor behaviors.

A better default is to write to stderr, since it
is 9P debug info that is better immediately printed,
and not user info that is better handled by syslog().
As a result, -f is obsolete and thus removed.
Redirect responsibility is now on rc.
As a side effect, rc will fail if it doesn't
have permissions to write.

exportfs(4) is updated to reflect all changes
and with a better Synopsis.

oexportfs is changed to match exportfs.
oexportfs(4) is updated to reflect all changes.
The Synopsis is not changed due to the number of flags.

8c228a123f mk for only supported archs
http://fqa.9front.org/fqa1.html#1.2 states the supported archs.
However, clean and nuke also remove build files for 0 (spim) and q
(power).  'mk all' using those archs fails; 'mk kernels' also tries to
build all the kernels, even those which are not supported.  For
example, I tried to build the power arch (qc, qa, ql) and without
surprise it failed (when building dtracy): ...

The patch below skips over non-supported architectures.  Is that
something we want?  This way, 'mk kernels' should work without a
problem (tested on amd64).  Then if someone works on getting those
architectures supported again in the future, they can be added back
in.

97c6a1dd52 snoopy: fix dns nil pointer crashes when formating dns packets (thanks sl)
snoopy shares ndb/dns's dns parser code, but has its own
copy of rralloc() function, which is responsible to allocating
auxiolary data structures on an RR depending on the type.

ndb/dns gained some support for some new types, but snoopy's
copy of rralloc() was not updated, resulting the auxiolary
structures to be nil, and the shared parsing routines crashes
when trying to dereference them.

this just syncs the copies, we might consider moving rralloc()
into its own file so it can be completely shared.

cfebf83947 git: better handling of absolute paths, regex metachars
Git currently gets a bit confused if you try to
manipulate files by absolute path.  There were also a
number of places where user-controlled file paths ended
up getting passed to regex interpretation, which could
confuse things.

This change mainly does 2 things:

	- Adds a 'drop' function which drops
	  a non-regex prefix from a string, and uses
	  that to manipulate paths, simplifies 'subst',
	  and removes 'subst -g', which was only used
	  with fixed regexes; sed does this job fine.
	- When getting a path from a user, we
	  make it absolute and then strip out the head

Along the way it cleans up a couple of stupids:

	- 'for(f in $list) if(! ~ $#f 0) use $f:
	  $f can't be a nil list because of
	  list flattening.
	- removes a useless substitution here:

	 	all=`$nl{{git/query -c $1 $2; git/query -c $2 $3} | sed 's/^..//' | \
			gsubst '^('$ourbr'|'$basebr'|'$theirbr')/*' | sort | uniq}

	  where git/query -c doesn't produce
	  paths prefixed with the query.
