2016-09-1939381: handle save/restore of variable values when "typeset"-related ↵Barton E. Schaefer1-2/+2
reserved words are prefixed by an assignment
2016-09-1639362: another race with pipeline handling.Peter Stephenson1-25/+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.
2016-09-1639359: Fix remaining race with orphaned subjob.Peter Stephenson1-1/+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.
2016-09-1639331: Reparent subjob on fork with exited superjob.Peter Stephenson1-1/+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.
2016-09-1339305: Fix error handling after parse for here document.Peter Stephenson1-1/+1
Keep the error status the same as before, but also retain the interrupt status if that was non-zero.
2016-08-3139125: More care needed decrementing SHLVL on exec.Stephane Chazelas1-4/+7
Not needed in subshell.
2016-08-2639104: do not hash relative paths in findcmd()Barton E. Schaefer1-1/+1
2016-08-0538991: Make 'whence -v autoloaded-function' shows the defining filename.Daniel Shahaf1-1/+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.
2016-06-1338653 + 38657: 'functions -T' tracing: recurse into anonymous functions.Daniel Shahaf1-3/+9
2016-04-2638350 (cf. Glenn Smith: 38348): Remove-all warning should warn about the ↵Barton E. Schaefer1-2/+2
root directory as well
2016-03-0938114: Fix hang using ^Z with command subst.Peter Stephenson1-2/+11
In subshells started to perform substitutions disable signals that require interactive handling.
2016-02-0337868: add 'static' to file local variablesJun-ichi Takimoto1-2/+0
2016-01-0137473: check for cshnullglob in command position.Barton E. Schaefer1-0/+5
2015-12-2537435 (+ fix typo): allow execution of empty files as "sh" scriptsBarton E. Schaefer1-1/+2
2015-12-2537434: POSIXBUILTINS "command" should prevent shell exit on errors from ↵Barton E. Schaefer1-3/+5
special builtins
2015-12-0437202: suppress WARN_CREATE_GLOBAL warnings after a forkPeter Stephenson1-1/+1
2015-12-04unposted: fix init_io() calls in previous changePeter Stephenson1-1/+1
2015-11-1137092: make nested ${(P)name} properly refer to parameter on returnPeter Stephenson1-7/+9
2015-10-1436853: replace pushheap/popheap by NEWHEAPS/OLDHEAPS in doshfunc() to ↵Barton E. Schaefer1-201/+201
optimize memory management Includes re-indentation that was not done in the posted patch.
2015-10-03unposted: back out 36707, add test case for 36766Barton E. Schaefer1-1/+1
2015-10-0336766: fix incorrect reset of noerrexit during "if" conditionsBarton E. Schaefer1-1/+2
2015-09-3036707: distinguish ERR_RETURN value of retflag so that execif() can ignore ↵Barton E. Schaefer1-1/+1
it in the test sublist
2015-09-2736651: WARN_CREATE_GLOBAL += math expressionsDaniel Shahaf1-1/+2
Without this, '() { (( x=42 )) }' and '() { for (( i=0; … )) }' wouldn't warn about $x and $i, respectively, being created global.
2015-09-0236378: skip directories when looking for files to autoloadPeter Stephenson1-1/+3
2015-08-1136104: change order of child_block() and dont_queue_signals() to resolve yet ↵Barton E. Schaefer1-1/+1
another race condition
2015-08-0936022 fix bug that some loop constructs could not be interrupted, revise ↵Barton E. Schaefer1-7/+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.
2015-07-2335849: close fd's from process substitution after forkPeter Stephenson1-2/+3
Leaving these hanging in parent could cause deadlock: test added.
2015-07-0935751: Fix ERR_RETURN and ERR_EXIT in "else"Peter Stephenson1-1/+7
2015-06-2935655: APPEND_CREATE option for POSIX copmatible NO_CLOBBERPeter Stephenson1-1/+2
2015-06-2735634: handle failure of gettempname() in namedpipe()Barton E. Schaefer1-0/+4
2015-06-2535604: create empty arrays in typeset with array=()Peter Stephenson1-9/+12
2015-06-24various posts: Implement assignment parsing for typeset.Peter Stephenson1-18/+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.
2015-06-1635493: erase $_ when the command line is an assignmentBarton E. Schaefer1-0/+1
2015-06-02GLOB_ASSIGN should only affect scalar assignmentsMikael Magnusson1-2/+2
2015-05-2835318: POSIX_BUILTINS behaviour for getopts.Peter Stephenson1-4/+8
It needs to keep OPTIND, as well as the index within the string pointed to by OPTIND, global in this case.
2015-05-22Tweak test for function level of exit.Peter Stephenson1-1/+1
Sometimes local level jumps so we need an inequality instead of an equality.
2015-05-13users/20203: nested functions in always blocks when exit pendingPeter Stephenson1-1/+9
2015-04-2834989: AUTO_CD needs to call cd --.Peter Stephenson1-0/+1
Otherwise directories looking like options do the wrong thing.
2015-04-2834979: Preserve job text when doing shell job fix.Peter Stephenson1-1/+14
This handles list_pipe_text in execlist() along with other variables that are saved and restored and, in the special case of source, cleared.
2015-04-2434955: save and restore list_pipe_job with its friendsPeter Stephenson1-2/+4
This is needed to stop source() messing up job control.
2015-04-1534900: assignment before an "exec".Peter Stephenson1-7/+14
Without POSXIBUILTIN: restore after, so we only get side effects. With POSXIBUILTIN: keep set variable
2015-04-1534887: Fix POSIX_BUILTINS with assignment.Peter Stephenson1-7/+21
In the form var=val command special-builtin-or-func the var is restored after execution, unlike the case where "command" is absent. Clear up case in code that handles this. Add tests.
2015-02-2034590: queue_signals() around more scopes that manipulate global stateBarton E. Schaefer1-1/+3
2015-02-1634530: PRINT_EXIT_VALUE with anonymous functions.Peter Stephenson1-2/+12
Simpler fix, avoiding structural changes.
2015-02-1334546: further $_ with anon function fix.Peter Stephenson1-4/+13
Also add tests.
2015-02-1234519: $_ for arguments of anonymous functionPeter Stephenson1-1/+4
2015-02-1234514: Back out 34485, an alternate solution needs to be worked out.Barton E. Schaefer1-25/+26
(Tweaked to keep the unrelated hunk of the E01 test.)
2015-02-0934485: More rationalisation for anonymous functions.Peter Stephenson1-26/+25
Don't attempt to treat as "simple" case as there are too many hidden problems. Pull out some post-execution functions to a common case in execcmd().
2015-01-20users/19751: remove error on failure to close file descriptor by number.Peter Stephenson1-1/+6
Keep it when closing file descriptor stored in a variable, i.e. explicitly opened by the user.
2015-01-1834322: bug with interface to parsestr() etc.Peter Stephenson1-4/+5
Was showing up in places like ${(e)...} where command substitution could reallocate the token string, but actually there was never any guarantee that the lexer wouldn't do that, so this was always a bit iffy.
