zsh/Src/utils.c, branch zsh-5.1.1

36380: Avoid gcc case syntax

2015-09-01T21:18:17Z

36376: handle signals during read1char() so it is possible to interrupt correct/correctall prompts

2015-09-01T18:26:06Z

36262: Replace fix for missing unmeta in chdir().

2015-08-21T09:04:13Z

It was needed in the argument to one of a pair of lchdir()s rather than within zchdir(). Add tests for the case of a character with 0x83 within it.

36227: attempt to fix metafication problem with ztrftime.

2015-08-18T15:20:48Z

fmt is treated as metafied on entry; use returned length to ensure we metafy or output the correct length if there are embedded nulls.

35928: '%-m' should work even if not supported by strftime(3)

2015-08-07T18:39:51Z

Also clarify document.

35809: fix $((...)) completion by _expand widget.

2015-07-25T20:36:54Z

This changes internal quoting of the form still including tokens not to add unnecessary internal backslashes.

35872: protect against NULL pointers in unmeta

2015-07-23T09:04:09Z

35826: add getsparam_u() to return unmetafied string, use it for a number of references to non-special params

2015-07-22T19:52:24Z

35745: ztrftime: Pass everything unhandled to the system strftime()

2015-07-09T13:32:55Z

Add non-metafied character length handling.

2015-06-12T08:30:39Z

Use this in regex module and add test using $'\ua0'. Rename mb_metacharinit() to mb_charinit() as it does not involve metafied characters.

35386: expand tabs where useful in builtins outputing function.

2015-06-05T10:21:22Z

Also add to zed -f. Option is -x .

35353: print -x and print -X expand tabs

2015-06-02T08:17:04Z

35067: Add (b) parameter flag for pattern char backslashing.

2015-05-10T18:19:34Z

Doc tweak from Daniel in 35071. Includes test.

35064: rename ISPRINT to ZISPRINT to avoid conflict

2015-05-09T07:02:37Z

34636: replace broken isprint() on Mac OS X

2015-03-04T16:48:34Z

34587: ensure multibyte characters don't overflow.

2015-02-20T16:25:54Z

They could start incorporating tokens, with bad karma. Add test.

34466: Fix double unmeta in rm verification

2015-02-09T04:13:34Z

34403: refine 34399 to avoid settyinfo() when the input descriptor is not a TTY

2015-01-27T02:48:25Z

34399: fix polltty thinko from 34365

2015-01-26T00:07:49Z

Also add missing ChangeLog entry for 34365.

34365: History lockfile backoff: randomised time.

2015-01-25T20:29:18Z

Time doubles on each lock failure. zsleep() provides microsecond resolution for sleep; uses nanosleep() if available, else select via means of existing tty poll function.

34369: document error and warning codes

2015-01-25T18:08:29Z

34383: ztrdup() should be dupstring() in new cd code

2015-01-25T18:03:20Z

34331: better handling of NULL in cd.

2015-01-22T20:20:15Z

Problem was return from symbolic link expander in weird cases where there file system isn't behaving itself properly.

34322: bug with interface to parsestr() etc.

2015-01-18T22:38:57Z

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.

34138: wcs_nicechar: only deref widthp if it was given

2015-01-06T22:51:18Z

34108: Don't leak ifs stuff

2015-01-06T22:51:00Z

Found by Coverity (Issue 1255785).

34092: fix miscount of symlink resolution for "..".

2015-01-04T19:42:45Z

This caused problems with expanding a path with ".." in "whence -S".

34091: typo with "whence -s" expansions

2015-01-04T19:05:39Z

users/19667: whence -S shows intermediate steps in symlink expansion

2015-01-02T21:32:51Z

33876: etc.: Separate errors and keyboards interrupts

2014-12-11T09:41:17Z

Combination of 12 commits from interrupt_abort branch. Basic strategy is to introduce bits to errflag and to set and reset them separately. Remove interrupt status on return to main keymap. Turn off ERRFLAG_INT for always block. Restore bit thereafter: we probably need a new variable in order to allow user interrupts to be reset in the always block. Add TRY_BLOCK_INTERRUPT This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too. Ensure propagation of SIGINT from exited job. If received by foreground job, shell uses ERRFLAG_INT, not ERRFLAG_ERROR, to set the new state. Reset errflag before precmd() Add always block in _main_completion to fix ZLS_COLORS Ensures we get the right state of $ZLS_COLORS at the end of _main_complete even if there's an interrupt. However, the "right state" is a bit messy as it depends on styles.

33932: revise boundary check in unmeta()

2014-12-08T17:41:01Z

33894: boundary conditions in unmeta(), unmetafy()

2014-12-07T19:20:01Z

Check that we aren't running off the end of the string when converting the next byte after a Meta byte. This is just defensive programming in case of bad metafied strings coming through from gettokstr(), some repairs there are likely still needed.

33818: fix types passed to sizeof detected by coverity as being wrong

2014-11-30T22:19:55Z

33793: add 0b binary interpretation to integer constants

2014-11-26T17:26:58Z

Marc Finet: problems with working directory rationalisation.

2014-11-13T19:44:01Z

Ensure the length of the directory is kept up to date. Abort following symlinks as soon as there's an error.

33320 (cf. PWS 33311): revert 33069, fix lexing of bangchar during completion

2014-10-02T15:39:43Z

add typtab_flags bits (replaces specialcomma boolean) to record any unusual handling of typtab entries; signal safety; make bangchar non-special during completion lexing of the command line.

Increase size of xbuf2 in xsymlinks to make gcc FORTIFY_SOURCE=2 happy.

2014-08-17T17:32:02Z
