32091: WARN_CREATE_GLOBAL false positive.

In cases like () { foo=bar =true; }

31919: fix deadlock when a shell builtin with a multio redirection is used on the left side of a pipeline

2013-10-27T22:42:00Z

Make sure stdin/out/err file descriptors are closed for the multio copy process, which means not re-using those descriptors after they are closed and marked FDT_UNUSED in fdtable[]. For completeness, initialize their fdtable[] state to FDT_EXTERNAL.

31912: in closemn(), distinguish closing for >&- from closing for a real redirect

2013-10-27T18:27:41Z

Fixes knock-on multios bug introduced by workers/20666 way back in 2005.

Use VERBOSE option in execstring()

2013-10-19T22:08:24Z

31846: fix NOEXEC option in execsimple() optimisation

2013-10-18T22:42:07Z

31832: make execrestore() more signal-safe.

2013-10-17T14:35:05Z

31809: Make whitespace clear in trace output for patterns.

2013-10-10T16:12:50Z

31549: Fix third problem with file descriptor management.

2013-07-21T17:23:04Z

Replace ad-hoc subsh_close file descriptor for pipe management with the new job-based addfilelist() mechanism.

31545: Use of FD_CLOEXEC to remove possibility of fd reuse.

2013-07-20T22:23:18Z

File descriptors of mmap'd dump files are closed if and only if an exec is performed.

31528: use job table to record file descriptors associated with process subst

2013-07-17T20:33:16Z

31444: Basic code for enable/disable -p

2013-06-13T17:38:33Z

31376: Make sure every execve() is prefixed by winch_unblock()

2013-05-05T18:33:36Z

This was suggested by Bart Schaefer in 31375.

Revert "31372: Do not block SIGWINCH for child processes"

2013-05-05T18:33:07Z

This reverts commit f8ab02ad5f4226e46ab54e681a3e0404fdc1a9a6. As Bart suggested in 31375.

31372: Do not block SIGWINCH for child processes

2013-05-05T09:27:39Z

Something similar may also be needed in the zpty and clone modules.

31141: Tighten NO_CLOBBER restrictions on {fd} syntax

2013-03-10T21:45:04Z

to apply only if $fd is exactly an fd and nothing else.

30876: fix obscure failures to propagate non-zero status

2012-12-13T10:36:59Z

from optimised simple commands within lists

30726: make shell options passed to emulate stick along with the emulation

2012-10-11T20:14:01Z

30724: shell code optimisd to use execsimple() doesn't have a valid thisjob

2012-10-11T16:36:14Z

30722: fix some cases where emulations or options were not propagated properly

2012-10-07T19:46:46Z

from the emulate command

30633: "functions -T" only traces marked function, not called functions

2012-08-21T18:03:01Z

30307 plus tweak suggsted by Wayne: use %lld for zlong when long long

2012-03-05T10:06:28Z

30272 (tweaked): most failures of fork() cause non-interactive shells to

2012-03-01T03:33:18Z

exit nonzero; bad options to "exec" cause exit under POSIX_BUILTINS.

30181, plus rename of PF_* flags to PREFORK_*:

2012-02-12T20:27:48Z

Pass sh-wordsplitting instructions to paramsubst() using flags, avoiding side effects of explicitly setting and unsetting the SHWORDSPLIT option.

2012-01-16T22:14:11Z

30000 plus some comments: Better POSIXJOBs behaviour.

2011-12-12T19:25:02Z

29677: Do not allow external processes in a pipeline to become suspended

2011-08-14T18:34:27Z

when the end of the pipe is controlled by a builtin in the current shell which cannot itself become suspended.

29654: "wait" should resume stopped jobs identified by process ID as well

2011-08-10T03:21:15Z

as by job number; temporary (?) workaround for pipelines getting lost if TSTP is delivered when a shell builtin is the tail of the pipe.

29561: Allow closing of fd's not recorded by the shell

2011-07-25T10:20:09Z

Check the return value of all pipe(), read(), and write() calls.

2009-12-16T18:39:06Z

Gets rid of all the remaining "ignoring return value" compiler warnings, and makes some read/write operations safer by ensuring that an EINTR is handled.
