2018-10-0843616: Various parameter setting and display fixes.Peter Stephenson1-63/+109
Mostly to do with typeset -p and tied variables and their interaction. Some general tied variable fixes.
2018-09-2543546: "typeset -p" should show -U flagStephane Chazelas1-0/+7
2018-08-0943264: fix ${+assoc[nonexistent]} with KSH_ARRAYSPeter Stephenson1-1/+1
2018-05-1442297: (e) subscript flag needs extra work with scalarsdana1-3/+17
2018-05-13Nelson H. F. Beebe: 19597 (rebased 42369): return Inf, NaN etc from floating ↵Oliver Kiddle1-4/+12
point operations instead of errors to allow non-stop IEEE 754 arithmetic
2018-04-0742597: plug memory leak found by coverityOliver Kiddle1-1/+3
2018-01-04Avoid crash copying empty hash table.Stephane Chazelas1-4/+7
Visible with typeset -p.
2017-10-0241787 (plus minor tweaks): use $FUNCSTACK for function nesting depth.Peter Stephenson1-0/+14
Initialised from existing configuration value.
2017-10-01Add typeset -p1, like typeset -p with newlinesPeter Stephenson1-15/+38
2017-09-2741764 (test tweaked): allow [key]+=value when modifying arraysPeter Stephenson1-7/+32
2017-09-2541747: Don't create hash entry if just checking existence.Peter Stephenson1-3/+6
Pass a flag in indicating this case.
2017-09-24Updates for ksh array element syntax.Peter Stephenson1-65/+127
Move detection of key/value pairs down into prefork(). Detect normal array assignment and [key]=val array assignemnt separately. Mark key / value pairs with Marker and pass up flag. Deal with marked triads specially later on.
2017-09-14More [key]=value tweaksPeter Stephenson1-3/+5
Some rephrasings. Update typeset -p for associative arrays to use new syntax.
2017-09-13First go at var=([key]=value) syntax.Peter Stephenson1-0/+66
Works for both normal and typeset case, also var+=... Still to do: allow to be mixed with straight array assignment, improve typeset -p, implement [key]+=value.
2017-06-0541225: sethparam() should not attempt to change special parameters into hashesBarton E. Schaefer1-6/+11
2017-04-2140990: Fix crash with bogus path in sh emaulation.Peter Stephenson1-14/+37
When startying in sh emulation don't link PATH-style parameters to array equivalents. To allow this to function, don't check for the linkage when exporting the colon-separated parameter.
2017-04-0340932: Parameter subscripts need to count parentheses.Peter Stephenson1-3/+8
Otherwise they can terminate in the middle of an expression.
2017-03-0840799: fix $- expansion partly broken by 40760Barton E. Schaefer1-1/+3
2017-03-0840745 + 40753: Fix 'unset ZLE_RPROMPT_INDENT' not restoring the default ↵Daniel Shahaf1-1/+19
behaviour. To reproduce: RPS1=foo ZLE_RPROMPT_INDENT=42 unset ZLE_RPROMPT_INDENT
2017-03-0440781: optimize array assignment, similar to 39995 for string assignmentSebastian Gniazdowski1-15/+48
2017-02-0240486: Don't warn on creation of MATCH etc. in regex.Peter Stephenson1-5/+32
This because they are created implicitly rather than by explicit user request, so the warning may not be useful.
2017-02-0140460: WARN_NESTED_VAR: Don't warn when assigning to a slice of an existing ↵Daniel Shahaf1-6/+13
array
2017-01-2640423: WARN_NESTED_VARS, conversion the other wayPeter Stephenson1-8/+8
2017-01-2640422: More WARN_NESTED_VAR cases.Peter Stephenson1-8/+9
Converting type when using a calling scope was broken in the original patch.
2017-01-2540413: WARN_NESTED_VAR subscripted variable fix.Peter Stephenson1-1/+5
No warning needed on paramter that's created temporarily to help assignment.
2017-01-2340391: Add WARN_NESTED_VAR option and functions -W.Peter Stephenson1-23/+43
These are companions to WARN_CREATED_GLOBAL, warning when a variable from an enclosing scope is altered.
2017-01-0540270 (after 39995): Add cross-reference for robustness.Daniel Shahaf1-0/+2
2016-12-2840231: Optimise setarrvalue().Sebastian Gniazdowski1-16/+34
2016-12-0340068: Abort execution when setuid/setgid fail.Daniel Shahaf1-4/+4
The incumbent code would print an error message and continue execution with the previous uid/gid values, not even setting lastval: % UID=42 id -u; echo $? zsh: failed to change user ID: operation not permitted 1000 0 %
2016-12-0340067: internal: Document 'cmatcher', parse_cmatcher(), 'comptoend', ↵Daniel Shahaf1-1/+17
unsetparam_pm(), and getindex().
2016-11-2940032: consistency in handling of subscript slices outside the bounds of an ↵Barton E. Schaefer1-2/+9
array parameter unposted: README: example describing 40032
2016-11-2039900: Add TERMINFO_DIRS special like TERMINFO.Guillaume Maudoux1-0/+31
Although this is a colon-separated array there is no tied array.
2016-11-2039995 (from 39977): Optimise string parameter assignment.Peter Stephenson1-8/+31
If setter is the standard one and string length is unchnaged we can copy into place.
2016-11-2039992: setarrvalue: Allocate a correctly-sized array.Daniel Shahaf1-2/+10
No memory was lost; the array was allocated with room for one (char *) element more than was required.
2016-11-1539937: fix a problem introduced by 39886.Jun-ichi Takimoto1-3/+4
$a[i,j] should become an empty array if i>j.
2016-11-1039893: use arrdup_max() to show explicitly the difference in two code branchesBarton E. Schaefer1-3/+2
no functional change
2016-11-1139874/0001: setarrvalue: Remove needless initialization.Daniel Shahaf1-2/+2
2016-11-0939887: no need to conditionalise assignment of strlen()Peter Stephenson1-6/+2
2016-11-0939886 based on 39877: Optimise arrdup to arrdup_max.Peter Stephenson1-7/+17
Only duplicate as much of the array as is needed.
2016-11-0939875: add dupstring_glen to avoid redundant strlen callsSebastian Gniazdowski1-2/+2
2016-11-0839871: cut down number of strlen()s in getstrvalue()Sebastian Gniazdowski1-4/+13
2016-11-0839869: can transfer ownership of core of array when assigningSebastian Gniazdowski1-3/+8
2016-10-2939758: revise 39704 for array and hash parameters; more POSIXBUITINS tweaks forBarton E. Schaefer1-8/+8
export 39704 was commit 0f5e670, forgot to reference article number in that log. "typeset -p" outputs "typeset" for array and hash parameters, even when exported, because those types can be marked export but are never pushed to the enviroment. For POSIXBUILTINS, "export var" does not implicitly set $var, and its export state is preserved when assigned (but not when explicitly unset).
2016-10-24"typeset -p" uses "export" commands or the "-g" option for parameters that ↵Barton E. Schaefer1-5/+17
are not local to the current scope
2016-10-0339545: Add some missing unqueue_signals().Peter Stephenson1-0/+2
All of these are added simply to fit existing logic in other branches.
2016-09-3039519: restore missing PM_EXPORT flags.Peter Stephenson1-0/+1
This was missing when exporting using USE_SET_UNSET_ENV coce variant.
2016-09-3039498: use PRIVILEGED option to decide on problematic parameter importsPeter Stephenson1-3/+3
2016-09-28unposted: change '\0' to NULL to silence spurious compile warning.Bart Schaefer1-1/+1
params.c:830:13: warning: expression which evaluates to zero treated as a null pointer constant of type 'char *' [-Wnon-literal-null-conversion] *envp = '\0';
2016-09-2839460: Don't import PS4 if running as root.Peter Stephenson1-3/+30
There was an exploit in bash using SHELLOPTS to turn on xtrace, however this can't happen in zsh, so this is simply a precaution.
2016-09-1639332: support ksh's [[ -v varname ]] condition for checking if variables ↵Oliver Kiddle1-0/+30
are set
