* 31919: fix deadlock when a shell builtin with a multio redirection is used ↵Barton E. Schaefer2013-10-271-2/+2
| | | | | | | | | on the left side of a pipeline 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 ↵Barton E. Schaefer2013-10-271-5/+5
| | | | | | redirect Fixes knock-on multios bug introduced by workers/20666 way back in 2005.

* 31549: Fix third problem with file descriptor management.Peter Stephenson2013-07-211-17/+1
| | | | | 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.Peter Stephenson2013-07-201-0/+2
| | | | | File descriptors of mmap'd dump files are closed if and only if an exec is performed.

|
* 31376: Make sure every execve() is prefixed by winch_unblock()Frank Terbeck2013-05-051-0/+6
| | | | This was suggested by Bart Schaefer in 31375.
* Revert "31372: Do not block SIGWINCH for child processes"Frank Terbeck2013-05-051-3/+1
| | | | | | This reverts commit f8ab02ad5f4226e46ab54e681a3e0404fdc1a9a6. As Bart suggested in 31375.
* 31372: Do not block SIGWINCH for child processesBart Schaefer2013-05-051-1/+3
| | | | Something similar may also be needed in the zpty and clone modules.
* 31141: Tighten NO_CLOBBER restrictions on {fd} syntaxPeter Stephenson2013-03-101-1/+8
| | | | to apply only if $fd is exactly an fd and nothing else.

| | | | from optimised simple commands within lists
* 30726: make shell options passed to emulate stick along with the emulationPeter Stephenson2012-10-111-6/+101

|
* 30722: fix some cases where emulations or options were not propagated properlyPeter Stephenson2012-10-071-1/+1

* 30633: "functions -T" only traces marked function, not called functionsPeter Stephenson2012-08-211-2/+13
|
* 30307 plus tweak suggsted by Wayne: use %lld for zlong when long longPeter Stephenson2012-03-051-0/+4
|
* 30272 (tweaked): most failures of fork() cause non-interactive shells toBart Schaefer2012-03-011-11/+12
| | | | exit nonzero; bad options to "exec" cause exit under POSIX_BUILTINS.
* 30181, plus rename of PF_* flags to PREFORK_*:Peter Stephenson2012-02-121-3/+3
| | | | | | Pass sh-wordsplitting instructions to paramsubst() using flags, avoiding side effects of explicitly setting and unsetting the SHWORDSPLIT option.

* 30000 plus some comments: Better POSIXJOBs behaviour.Peter Stephenson2011-12-121-4/+25
| | | | | | Don't restore default SIGTTOU etc. behaviour if still doing job control. Only carry on doing job control in subshell if it's a real (...) subshell

* 29677: Do not allow external processes in a pipeline to become suspendedBart Schaefer2011-08-141-0/+2
| | | | | 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 wellBart Schaefer2011-08-101-1/+3
| | | | | as by job number; temporary (?) workaround for pipelines getting lost if TSTP is delivered when a shell builtin is the tail of the pipe.
