It appears that POSIX intends to add a -d X option to the read command
in its next version, so it can be used as -d '' (to specify a \0 end
character for the record read, rather than the default \n) to accompany
find -print0 and xargs -0 options (also likely to be added).

Add support for -d now.   While here fix a bug where escaped nul
chars (\ \0) in non-raw mode were not being dropped, as they are
when not escaped (if not dropped, they're still not used in any
useful way, they just ended the value at that point).

PR bin/56972  Fix escape ('\') handling in sh read builtin.

In 1.35 (March 2005) (the big read fixup), most escape handling and IFS
processing in the read builtin was corrected.  However 2 cases were missed,
one is a word (something to be assigned to any variable but the last) in
which every character is escaped (the code was relying on a non-escaped char
to set the "in a word" status), and second trailing IFS whitespace at
the end of the line was being deleted, even if the chars had been escaped
(the escape chars are no longer present).

See the PR for more details (including the case that detected the problem).

After fixing this, I looked at the FreeBSD code (normally might do it
before, but these fixes were trivial) to check their implementation.

Their code does similar things to ours now does, but in a completely
different way, their read builtin is more complex than ours needs to
be (they handle more options).   For anyone tempted to simply incorporate
their code, note that it relies upon infrastructure changes elsewhere
in the shell, so would not be a simple cut and drop in exercise.

This needs pullups to -3 -4 -5 -6 -7 -8 and -9 (fortunately this is
happening before -10 is branched, so will never be broken this way there).

 -

Don't output the error for bad usage (no var name given)
after already writing the prompt (set with the -p option).

That results in nonsense like:
	$ read -p foo
	fooread: arg count

While here, improve the error message so it means something.

Now we will get:
$ read -p foo
read: variable name required
Usage: read [-r] [-p prompt] var...

[Detected by code reading while doing the work for the previous fix]

Redo the way the builtin cmd 'ulimit' getopt() (nextopt() really, but it
is essentially the same) arg string is generated, to lessen the chances
that the table of limits, and the arg string that allows limits to be
reported or set will get out of sync.   They weren't (as long as we didn't
grow an RLIMIT_SWAP) this is just tidier.

While here, reorder the limits table fields, and shrink a couple that
were needlessly wasteful, to save some space -- for most architectures
this should save 8 bytes per table entry (there are currently 13).
(Some minor code bloat offsets this slightly because of int type
promotions now required).

NFCI.

While doing the previous change, I noticed that when used in a
particularly perverse way, the error message for a bad octal
constant as the new umask value could incorrectly claim that the
-S option (which would need to be present to cause this issue)
was the detected bad value.   Fix that to report the actual
incorrect arg.

And while fiddling, also check for args to umask that are too big
to be sane mask values (the biggest permitted is 07777) and use
mode_t as the mask variable type, rather than int.

Have the ulimit command watch for ulimit -n (alter number of available fds)
and keep the rest of the shell aware of any changes.

While here, modify 'ulimit -aSH' to print both the soft and hard limits
for the resources, rather than just (in this case, as H comes last) the
hard limit.   In any other case when both S and H are present, and we're
examining a limit, use the soft limit (just as if neither were given).

No change for setting limits (both are set, unless exactly one of -H
or -S is given).   However, we now check for overflow when converting
the value to be assigned, rather than just truncating the value however
it happens to work out...

- - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total
address space available to processes.  this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- - adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- - add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- - patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- - patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- - update irix, svr4, svr4_32, linux and osf1 emulations to support
this information.  (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897.  it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

Fix the way the 'read' builtin processes IFS.  In particular:
- IFS whitespace is now processes correctly,
- Trailing non-whitespace IFS characters are added to the last variable
  iff a subsequent variable would have been assigned a non-null string.
Now passes the 'read' tests in http://www.research.att.com/~gsf/public/ifs.sh

Fixes from David Laight:
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
  (so I could unset -e PS1 before running the test shell...)
