* 39958: Add extra byte to PATH_MAX allocations.Peter Stephenson2016-11-171-8/+8
| | | | | This ensures we've got enough space for a null, although this isn't always needed.
* 39915: whence: Honor PATH_DIRS option for arguments that start with './' or ↵Daniel Shahaf2016-11-171-7/+16
| | | | | | '../'. While here, add some docstrings.
* 39901: No EXIT trap on LHS of pipeline.Peter Stephenson2016-11-101-0/+4
| | | | | There is a special case if the LHS is a shell construct. Add unit tests for both cases.
* 39571: Fix ERR_EXIT bug with && and function.Peter Stephenson2016-10-051-6/+6
| | | | | "foo && bar" inside a function could cause the code outside the function not to perform ERR_EXIT or ERR_RETURN when needed.
* 39568: "! <complex-command>" suppresses ERR_EXITPeter Stephenson2016-10-051-2/+7
|
* 39566: Improve usefulness of command_not_found_handler.Peter Stephenson2016-10-051-5/+8
| | | | | | | Don't behave as if command not found if return status is non-zero as this may simply be the return status of the replacement command. Let the function report a command not found instead.
* 39545: Add some missing unqueue_signals().Peter Stephenson2016-10-031-0/+3
| | | | All of these are added simply to fit existing logic in other branches.
* 39521: Refactor start of execcmd().Peter Stephenson2016-10-031-46/+81
| | | | | | By splitting into _analyse and _exec execpline2() has easier access to the state at the start of execution. Use this to ensure we fork if this is a builtin with no arguments.
* 39540: "! command" should suppress ERR_EXIT and ERR_RETURNPeter Stephenson2016-10-021-2/+6
|
* 39517: back off 39502 (WC_ASSIGN causes fork in pipe).Peter Stephenson2016-09-301-1/+1
| | | | This isn't a robust fix as WC_ASSIGNs simply precede the main wordcode.
* 39507: TMPSUFFIX for =(...)Barton E. Schaefer2016-09-291-0/+9
|
* 39470: failure to open a supposedly unique temp file name should result in ↵Barton E. Schaefer2016-09-291-5/+11
| | | | | | an error Also band-aid for signal-related race conditions in temp file name generation
* 39502: Fork for assignment in LHS of pipeline.Peter Stephenson2016-09-291-1/+2
| | | | | | | foo=bar | stuff left the value of foo set to bar as we didn't realise we needed to fork.
* 34943: Fixes for "command" with multiple options.Peter Stephenson2016-09-291-37/+116
| | | | | | These need to combine properly, and alos "command -p" with either -v or -V needs to search for builtins and then using the default system path.
* 39437: use list_pipe_pid in assignment for clarityBarton E. Schaefer2016-09-271-1/+1
|
* 39436: Pass on status of SIGINT better.Peter Stephenson2016-09-251-1/+2
| | | | | | Set lastval to 128 + SIGINT on interrupt. Don't execute builtin if already interrupted at that point.
* 39435: Further fix for pgrp of funny pipelines.Peter Stephenson2016-09-251-1/+2
| | | | | Don't set gleader of SUBJOB at the point of creation if the SUPERJOB has no processes yet.
* 39381: handle save/restore of variable values when "typeset"-related ↵Barton E. Schaefer2016-09-191-2/+2
| | | | reserved words are prefixed by an assignment
* 39362: another race with pipeline handling.Peter Stephenson2016-09-161-25/+9
| | | | | | When forking the shell to control the right hand side, the forked subshell now always starts its own process group, to avoid getting a spurious additional SIGSTOP.
* 39359: Fix remaining race with orphaned subjob.Peter Stephenson2016-09-161-1/+43
| | | | | | When shell is forked to run right hand side of pipieline it should use its own PID as process group if the left hand side of the pipeline has already exited.
* 39331: Reparent subjob on fork with exited superjob.Peter Stephenson2016-09-161-1/+18
| | | | | | | | | | | Fixes case of v() { { vim - } always { true } } ls | v ^Z fg Tentative fix: still a race at exit where zsh forked by ^Z is stopped when restarted.
* 39305: Fix error handling after parse for here document.Peter Stephenson2016-09-131-1/+1
| | | | | Keep the error status the same as before, but also retain the interrupt status if that was non-zero.
* 39125: More care needed decrementing SHLVL on exec.Stephane Chazelas2016-08-311-4/+7
| | | | Not needed in subshell.
* 39104: do not hash relative paths in findcmd()Barton E. Schaefer2016-08-261-1/+1
|
* 38991: Make 'whence -v autoloaded-function' shows the defining filename.Daniel Shahaf2016-08-051-1/+2
| | | | | | This may also fix a problem whereby the %x prompt escape evaluated to a function name rather than a filename, since %x is also backed by scriptfilename.
* 38653 + 38657: 'functions -T' tracing: recurse into anonymous functions.Daniel Shahaf2016-06-131-3/+9

* 38350 (cf. Glenn Smith: 38348): Remove-all warning should warn about the ↵Barton E. Schaefer2016-04-261-2/+2

* 38114: Fix hang using ^Z with command subst.Peter Stephenson2016-03-091-2/+11
| | | | | In subshells started to perform substitutions disable signals that require interactive handling.
* 37868: add 'static' to file local variablesJun-ichi Takimoto2016-02-031-2/+0

* 36707: distinguish ERR_RETURN value of retflag so that execif() can ignore ↵Barton E. Schaefer2015-09-301-1/+1
| | | | it in the test sublist
* 36651: WARN_CREATE_GLOBAL += math expressionsDaniel Shahaf2015-09-271-1/+2
| | | | | Without this, '() { (( x=42 )) }' and '() { for (( i=0; … )) }' wouldn't warn about $x and $i, respectively, being created global.
* 36378: skip directories when looking for files to autoloadPeter Stephenson2015-09-021-1/+3
|
* 36104: change order of child_block() and dont_queue_signals() to resolve yet ↵Barton E. Schaefer2015-08-111-1/+1
| | | | another race condition
* 36022 fix bug that some loop constructs could not be interrupted, revise ↵Barton E. Schaefer2015-08-091-7/+42
| | | | | | | | | | | signal queueing There are two underlying ideas here: (1) Keeping signals queued around anything that's doing memory management (including push/pop of the heap) has become crucial. (2) Anytime the shell is going to run a command, be it buitin or external, it must be both safe and necessary to process any queued signals, so that the apparent order of signal arrival and command execution is preserved.
* 35849: close fd's from process substitution after forkPeter Stephenson2015-07-231-2/+3
| | | | Leaving these hanging in parent could cause deadlock: test added.
* 35751: Fix ERR_RETURN and ERR_EXIT in "else"Peter Stephenson2015-07-091-1/+7

* 35604: create empty arrays in typeset with array=()Peter Stephenson2015-06-251-9/+12
|
* various posts: Implement assignment parsing for typeset.Peter Stephenson2015-06-241-18/+158
| | | | | | | | | | | | Typeset assignments now work like raw assignments except for no "+=" and no GLOB_ASSIGN. Documented in typeset builtin doc and mentioned in release notes. Tests to ensure basic sanity. Enabled by default, can be turned off by "disable -r" with typeset family of commands.
* 35493: erase $_ when the command line is an assignmentBarton E. Schaefer2015-06-161-0/+1
