* 34331: better handling of NULL in cd.Peter Stephenson2015-01-222-7/+12
| | | | | Problem was return from symbolic link expander in weird cases where there file system isn't behaving itself properly.
* 34329: add -S option to which and wherePeter Stephenson2015-01-201-2/+2
|
* users/19751: remove error on failure to close file descriptor by number.Peter Stephenson2015-01-201-1/+6
| | | | | Keep it when closing file descriptor stored in a variable, i.e. explicitly opened by the user.
* 34322: bug with interface to parsestr() etc.Peter Stephenson2015-01-189-26/+46
| | | | | | | 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.
* 34319: fix alias expansion in history for command substitutionPeter Stephenson2015-01-182-7/+21
|
* unposted: another dubious comment in hist.c fixedPeter Stephenson2015-01-161-2/+2
|
* unposted: improve comment on hist_in_word().Peter Stephenson2015-01-161-2/+6
| | | | | Commit f2a2f28f7 was a bit less clear about how hist_in_word() was used than it could be.
* 32413: turn off history word marking in cmd substPeter Stephenson2015-01-162-2/+22
|
* 34304: improve use of new cmd subst in completionPeter Stephenson2015-01-161-10/+103
|
* 34280: more widespread use of FORCE_FLOAT.Peter Stephenson2015-01-151-1/+12
| | | | Add the case of variables read for use in arithmetic expressions.
* 34287: preprocessor for signal name generation.Peter Stephenson2015-01-151-1/+10
| | | | | | Some gcc header files are difficult for the signames2.awk script to process, so if the preprocessor is gcc give the option -P to strip out the unwanted additions.
* Propagate float/integer type in arithmetic assignment.Peter Stephenson2015-01-121-1/+28
| | | | | | Add test. Mention this and also floating point mod change in README.
* 34230: call fmod() for modulo with floatsBarton E. Schaefer2015-01-111-3/+5
|
* 34234: use structures for normal and raw lexical buffer statePeter Stephenson2015-01-112-116/+118
|
* 34220: new $(...) handling needs to back up over alias expansionPeter Stephenson2015-01-101-0/+6
|
* unposted: update copyright for new Src/context.cPeter Stephenson2015-01-101-5/+5
|
* 34213: in previous patch, do not change usepm if it is already setBarton E. Schaefer2015-01-101-1/+1
|
* 34212: do not change unset-ness of special parameters when exporting themBarton E. Schaefer2015-01-101-2/+6
|
* select: Fix leak of 256 bytes on every loop when zle is not usedMikael Magnusson2015-01-101-1/+1
| | | | | | | Reproduce by yes | head -n 1000000 | zsh -c 'select foo in a b c; do done; sleep 30; echo' Found by Coverity (Issue 439082).
* hist: remove wrong NULL terminatorMikael Magnusson2015-01-101-1/+0
| | | | This actually writes a NULL to some arbitrary location in the caller function's stack. Found by Coverity (Issue 1255746).
* Rearrange context saving.Peter Stephenson2015-01-0914-299/+441
| | | | | | | Variables are now associated with the module that declares them, being initialised and saved/restored there. However, as many variables are used for communication between modules, many of them are set in multiple places, so the assignment is ambiguous.
* Fix a typo in bin_print error messageMikael Magnusson2015-01-091-3/+3
|
* Fix command substitutions to parse contents as they are read in.Peter Stephenson2015-01-085-193/+359
| | | | | | | Do this by refactoring misnamed lexsave()/lexrestore() to allow continuity of history and input. Add test.
* 34154/34155: reorder bin_print() to avoid leaking the output descriptor when ↵Barton E. Schaefer2015-01-071-29/+34
| | | | incorrect/incompatible options were passed
* 34144: allocate origline by ztrdup(), not by dupstring()Jun-ichi Takimoto2015-01-072-3/+6
| | | | | If origline is allocated in heap, it will have been freed when menuselect() is called directly as a widget.
* 34122: module: allow NULL third argument as intendedBart Schaefer2015-01-061-1/+1
| | | | Found by Coverity.
* 34138: wcs_nicechar: only deref widthp if it was givenMikael Magnusson2015-01-061-1/+1
|
* 34120: compctl, jobs: Check contents instead of arrayMikael Magnusson2015-01-062-2/+2
| | | | | | text is an array in the struct, and can never be null. Found by Coverity (Issue 1255780).
* 34108: Don't leak ifs stuffMikael Magnusson2015-01-061-2/+2
| | | | Found by Coverity (Issue 1255785).
* 34107: getsubsargs: free ptr1 before returningMikael Magnusson2015-01-061-0/+1
| | | | Found by Coverity (Issue 439073).
* 34134: anon funcs: don't leak shf and related dataMikael Magnusson2015-01-061-0/+6
| | | | Found by Coverity (Issue 439076).
* 34112: typeset: fix leak of oldvalMikael Magnusson2015-01-061-0/+2
| | | | Found by Coverity (Issue 1255803).
* 34106: hist: use zhtricat instead of tricatMikael Magnusson2015-01-061-1/+1
| | | | Found by Coverity (Issue 1255769).
* 34113: whence: use dupstring to not leak memoryMikael Magnusson2015-01-061-1/+1
| | | | | All other assignments to buf use the heap, and it's never freed. Found by Coverity (Issue 1255786).
* 34119: complist: Fix leak of string in clnicezputsMikael Magnusson2015-01-061-0/+2
| | | | Found by Coverity (Issue 1255808).
* 34105: subst: remove dead codeMikael Magnusson2015-01-061-1/+1
| | | | Found by Coverity (Issue 1255810).
* 34121: compresult: Remove unneeded NULL checkMikael Magnusson2015-01-061-1/+1
| | | | | The variable is set to if NULL at the start of the function, and derefed on the previous line. Found by Coverity (Issue 1255843).
* 34104: compctl: Remove pointless checkMikael Magnusson2015-01-061-1/+1
| | | | | cc has already been derefed a bunch of times leading up to here. Found by Coverity (Issue 1255841).
* 34115: compcore: Fix size argument to zfreeMikael Magnusson2015-01-061-1/+1
| | | | | Found by Coverity (Issue 1255852), has no impact unless using --enable-zsh-mem, and even then it is minimal.
* 34117: zle: size_t is unsigned, use int insteadMikael Magnusson2015-01-061-1/+1
| | | | | | The function wctomb returns an int according to my manpage, and we furthermore check if it is negative, and then return it, and the function signature is int, so declaring it as an int seems to make more sense.
* 34116: computil: Check for NULL before passing to strlenMikael Magnusson2015-01-061-1/+2
| | | | | The rest of this function appears to be very careful about checking these, then forgets in this one spot. Found by Coverity (Issue 1255805).
* 34118: Don't crash when writing out history if HOST is unsetMikael Magnusson2015-01-061-1/+2
| | | | Found by Coverity (Issue 1255793).
* 34114: emulate: Handle aborting from mixed -L/-c correctlyMikael Magnusson2015-01-061-1/+2
| | | | Somehow Coverity found this (Issue 1255797, Failure to restore non-local value).
* 34103: fix ancient double-quote handling thinko in subst_parse_str()Barton E. Schaefer2015-01-061-2/+4
| | | | This doesn't seem to have mattered, but must in some obscure cases
* 34093: "whence" should always return nonzero when it finds that nothing ↵Barton E. Schaefer2015-01-061-15/+17
| | | | matches its arguments
* 34092: fix miscount of symlink resolution for "..".Peter Stephenson2015-01-041-0/+2
| | | | This caused problems with expanding a path with ".." in "whence -S".
* 34091: typo with "whence -s" expansionsPeter Stephenson2015-01-041-2/+2
|
* users/19671: remove confusion with whence -a.Peter Stephenson2015-01-021-1/+1
| | | | If the argument is a full path don't try to search the path for it.
* users/19667: whence -S shows intermediate steps in symlink expansionPeter Stephenson2015-01-022-13/+66
|
* 34070: fix starting position for memset() from 34005.Daniel Shahaf2014-12-281-1/+1
