2018-09-07T11:10:23Z

43396: Job control debug.

2018-09-06T09:39:45Z

Particularly for TTY ownership.

43227: fix memory leaks in term{cap,info}.c

2018-08-01T12:36:44Z

43075: Support nanosecond-precision time formatting

2018-06-20T22:29:56Z

* Teach ztrftime() %9. and %N for nanoseconds * Update prompt expansion to pass sub-second times for time formatting * Update zsh/stat to pass sub-second times for atime/mtime/ctime Patch heavily based on Oliver's earlier work @ workers/24059

42650: fix 42156 for zero-sized terminals

2018-04-15T18:06:43Z

Also fix harmless no-op typo from hand-applying 42636 for previous commit.

42636: fix GLOB_DOTS for !(RM_STAR_SILENT)

2018-04-15T17:57:27Z

Also fix paste-o in older log entry

42607, CVE-2018-1100: check bounds on buffer in mail checking

2018-04-07T16:28:38Z

42595: remove dead code flagged by coverity

2018-04-07T12:37:46Z

42560: silence sign-compare compiler warnings

2018-03-30T10:13:59Z

42539: prevent overflow of PATH_MAX-sized buffer in spelling correction

2018-03-28T07:00:58Z

42538: Temporarily set umask for here document.

2018-03-27T08:32:55Z

Done while signals are queued.

42480: optimize $#var for single-byte character sets

2018-03-26T01:01:25Z

42518, CVE-2018-1071: check bounds when copying path in hashcmd()

2018-03-24T14:04:02Z

42332: Special case unsigned printf formats.

2018-01-31T09:14:40Z

For constants we can avoid a conversion to signed by examining the expression before passing to math eval.

42156: new CHECK_RUNNING_JOBS option demanded by bash groupies

2017-12-22T20:21:23Z

Also new job options. Also suppress debug error if rows or columns are reported as zero as this is normal without a physical terminal.

unposted (cf. 41672): checkrmall: Record the 41672 bug in a TODO.

2017-09-21T18:17:19Z

unposted (cf. 41707): internal: Document the count==0 case of checkrmall().

2017-09-21T18:14:01Z

unposted: internal: Document zreaddir().

2017-09-11T15:06:08Z

Revert "41499 (with one further tweak): POSIX_STRINGS behaviour."

2017-08-08T18:04:49Z

This reverts commit 2eacbef91913fe967335812900d43cf2edfa54d9. Conflicts: ChangeLog

41499 (with one further tweak): POSIX_STRINGS behaviour.

2017-08-07T17:47:43Z

Ignore a terminating delimiter when splitting as separators despite being called separators are terminators.

41484: Make ${(q+)...} quote backsleshes.

2017-08-03T20:32:20Z

22760: fix partial string length reports with NO_MULTIBYTE

2017-07-02T19:29:00Z

41090: Replace iswprint() if unicode9 is enabled.

2017-05-12T03:10:13Z

If wcwidth() or iswprint() is broken, force enable unicode9.

40181: Fix buffer overrun in xsymlinks.

2017-05-09T16:49:18Z

There was no check for copying to the internal xbuf2 for a preliminary test.

40994: unmeta_one() need not count Meta

2017-04-23T14:58:44Z

40935: User names need metafying.

2017-04-10T08:55:06Z

On some systems they can contain 8-bit characters and on all systems this is logically correct anyway.

40763: count wide characters and Cmatcher pointers more sanely in cfp_matcher_pats(), and count characters in pattern_match() the same way to stay in sync

2017-03-09T05:26:55Z

Might not fix wide-char matching in completion matcher-lists but should avoid wild pointer crash

40760: Always tokenize unquoted - to Dash.

2017-03-07T10:43:58Z

This fixes use of pattern match character ranges in unusual contexts. Attempt to detect a tokenized - in cases where we don't care.

39982: $SPROMPT: Don't accept a spelling correction at space/tab.

2016-11-24T08:18:28Z

The patch also downscopes a couple of local variables, with no functional change.

39958: Add extra byte to PATH_MAX allocations.

2016-11-17T19:49:17Z

This ensures we've got enough space for a null, although this isn't always needed.

39943: no need to compute arrlen() in arrdup_max() when max == 0.

2016-11-15T18:04:14Z

39949: Special case for "-" in directory names.

2016-11-15T18:01:32Z

It can be sh-tokenized to Dash to allow for appearing in ranges after substitution, so needs to be turned back to "-" in that case.

39906: More multibyte optimisations for US-ASCII.

2016-11-14T10:12:04Z

This treats characters 0 to 0x7f as single byte US-ASCII along the lines we already do in other places in the code.

39886 based on 39877: Optimise arrdup to arrdup_max.

2016-11-09T11:54:57Z

Only duplicate as much of the array as is needed.

unposted: follow up to 39867: don't need test against zero

2016-11-08T10:51:03Z

39867, tweaked: Use cast to unsigned char to test character.

2016-11-08T10:09:26Z

We want the unsigned variant to be <= 0x7f. Use the normal STOUC() macro and turn this into a single test.

39825: optimise mb_metastrlenend() for 7-bit character.

2016-11-04T09:56:51Z

As the shell relies intimately on US-ASCII as a subset we can skip the multibyte functions if we are dealing with a complete 7-bit character.

39470: failure to open a supposedly unique temp file name should result in an error

2016-09-29T18:16:24Z

Also band-aid for signal-related race conditions in temp file name generation

39252: internal: quotestring: Drop the 'e' parameter, which no caller uses.

2016-09-11T09:22:18Z

39087: fix 'conditionally uninitialized' variables

2016-08-23T09:18:50Z

39046 + 39061: New :P history modifier.

2016-08-22T03:34:30Z

38971: Start using the new arrlen_ge() / arrlen_le() helpers.

2016-08-01T08:01:29Z

38973: Optimize indexing array parameters.

2016-08-01T08:01:28Z

% () { for 1 in $prefix/zsh/bin/zsh Src/zsh; do $1 -f -c 'a=( {1..1000000} ); repeat 3 time ( repeat 300 : $a[1] )'; done } ( repeat 300; do; : $a[1]; done; ) 1.68s user 0.01s system 98% cpu 1.718 total ( repeat 300; do; : $a[1]; done; ) 1.69s user 0.01s system 99% cpu 1.710 total ( repeat 300; do; : $a[1]; done; ) 1.69s user 0.01s system 99% cpu 1.714 total ( repeat 300; do; : $a[1]; done; ) 0.00s user 0.01s system 72% cpu 0.022 total ( repeat 300; do; : $a[1]; done; ) 0.00s user 0.01s system 72% cpu 0.022 total ( repeat 300; do; : $a[1]; done; ) 0.01s user 0.01s system 69% cpu 0.023 total

21603: Make read_poll more interruptible.

2016-06-02T10:01:39Z

If we interrupted the first read we still did the fallback read. This is wrong.

37946: make rm * warnings more informative.

2016-02-11T15:23:57Z

Now count files that would be deleted up to 100.

37868: add 'static' to file local variables

2016-02-02T16:25:33Z

37780: Care printing error if nothing to print.

2016-01-25T17:15:23Z

37776: Set errflag before calls to zwarning().

2016-01-25T15:43:06Z

This avoids an attempt to call zerr() or zerrnam() recusrively.

37678: Now possible to quote "-" in pattern range

2016-01-19T09:55:46Z

unposted: Extend docstring of callhookfunc().

2016-01-15T06:30:12Z

37348: Tests and fix for ${(q+)...}.

2015-12-08T15:08:24Z

Needs dupstring() for empty string case.

37344: restore old printable quoting, add ${(q+)...}.

2015-12-07T21:49:07Z

The \C- form is only used inside quotedzputs(). ${(q+)...} outputs a quotedzputs() representation.

37331: Use a single chracter to represent an MB_INCOMPLETE.

2015-12-07T18:54:03Z

This is as it is likely to appear as a single character in output even if it has multiple octets.

37326: comment only: multibyte string lenght/width counting

2015-12-06T16:39:57Z

37314: upgrade quotedzputs() for non-printable output.

2015-12-06T15:33:02Z

Use nicechar with $'..' quoting; upgrade nicechar() etc. to use suitable output.

37296: Avoid needless calloc().

2015-12-03T23:47:24Z

37191: fix strftime() expansion issue with %p and %P.

2015-11-22T18:14:13Z

In some locales the output from this can validly be empty, so we need to treat them specially.

unposted: small typo again

2015-10-24T20:00:30Z

unposted: small typo

2015-10-24T19:59:48Z

36944: extend fd management to zsocket

2015-10-24T19:48:47Z

36941: Mark file descripors in ztcp as used.

2015-10-24T19:24:35Z

Allow such file descriptors to be either internal and closed on exec or external and so managed explicitly by module.

36773: limit CORRECT / CORRECT_ALL to directory names in cases where it is obvious that a directory is expected

2015-10-04T21:01:08Z

36562: sanitize $PWD on import, per POSIX

2015-09-20T06:03:39Z

cf. 36554: remove unnecessary pointer dereference

2015-09-19T16:34:05Z

36552 plus test: fix Nularg string in quotestring(QT_DOLLARS)

2015-09-18T04:44:14Z

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.
