zsh/Src/utils.c, branch zsh-5.8

unposted: zerrmsg(): Fix macro guard missed in previous commit

2019-12-26T20:57:07Z

internal: Allow %L in zerrmsg() in non-debug builds, too.

2019-12-26T11:49:45Z

This will let error messages include long integers.

45064: Fix the mktemp() warning, in debug builds only.

2019-12-18T06:01:47Z

On Linux, linking to mktemp() generates the following warning: . utils.o: In function `gettempname': ./Src/utils.c:2229: warning: the use of `mktemp' is dangerous, better use `mkstemp' or `mkdtemp' The warning cannot be disabled. Work around that by using mkstemp() instead, and massage its output so it behaves like mktemp(). See the new comment for further details.

44714: Take account of CDABLE_VARS while checking spelling

2019-08-29T09:21:50Z

44307: allow for atoi() returning a negative number

2019-05-19T22:14:01Z

2018-12-30T09:42:07Z

43953: Fix rounding/truncation error in %. time-format specifier

2018-12-29T11:24:25Z

Also fixes an issue where %. couldn't be used more than once in a format string without strange results Tweaked very slightly per workers/43954

43790: failed mailstat could leak memory

2018-11-09T11:06:08Z

unposted: internals: Document sepjoin().

2018-10-14T14:02:34Z

43464: Another attachtty() fix.

2018-09-16T18:13:38Z

If list_pipe_job triggered more than once we need to know the most recent process group leader, so record that both if the attach happened in the main shell on in entersubsh(). Also don't pass back proocess group for ESUB_ASYNC subshells.

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.

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".
