* 45083: Add signal protection to execarith().Peter Stephenson2019-12-181-0/+3
| | | | | Otherwise we could get re-entrancy in memory functions when setting variables.
* 45076: internal: Simplify handling of try_tryflag. No functional change.Daniel Shahaf2019-12-181-6/+3
| | | | | try_tryflag isn't assigned anywhere, other than at initialization and by these lines, so we don't need to save and restore the value.

* 45064: Fix the mktemp() warning, in debug builds only.Daniel Shahaf2019-12-181-0/+25
| | | | | | | | | | | | 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.

* 45025: fix re-entrancy problem with memory management in readoutput().Peter Stephenson2019-12-151-25/+36
| | | | This could cause a signal received during $(...) to corrupt memory.
* 45009: POSIX_CD needs to suppress some forms of option.Peter Stephenson2019-12-121-1/+1
| | | | | Otherwise forms of argument allowed by POSIX are interpreted as options instead.
* 45001: Fix zero-length matches with ${...%...}Peter Stephenson2019-12-121-0/+6
| | | | As the shortest match is preferred, zero-length matches beat any other.

| | | | | This was in the glob qualifier and variable code but got missed out of the separate history modifier function.
* 44864: Avoid inifinite loop in tty init.Peter Stephenson2019-10-281-2/+16
| | | | | | | If we can't grab the terminal in interactive mode, give up after 100 goes. This is a completely arbitrary choice; we simply don't know what in the system could change the result of looping further.
* unposted: fix indentation (whitespace-only change)romkatv2019-10-281-30/+30
| | | | | | | Indentatin in moveto was broken by 3eea35d0 (my bad), making it difficult to read. This commit reverts it to what it used ot be. While at it, fix indentation in a few other places in the same file.

* bug fix: infinite loop when tty disappearsromkatv2019-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | When TTY disappears and there is at least one fd watcher, raw_getbyte() can enter an infinite loop where it keeps calling poll() over and over again. To reproduce, open a terminal, start zsh and type this: rm -f /tmp/fifo mkfifo /tmp/fifo exec 3<>/tmp/fifo do-nothing() {} zle -F 3 do-nothing Then make TTY disappear. For example, kill the parent with `kill -9 $PPID` and close the terminal window if it's still there. Observe that zsh is consiming 100% CPU. Note that do-nothing() never gets called. This patch makes the poll() loop in raw_getbyte() terminate when TTY is signalling POLLHUP. This makes the behavior consistent with the case where TTY disappears while no fd watchers are installed.

* fix multiple bugs in countpromptromkatv2019-06-191-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Height off by one in the presence of meta characters at the end of the line. The following prompt has height 2 but countprompt used to return 3. PROMPT="${(pl.$COLUMNS..-.)}%f"$'\n' You can observe the effects of the bug with esc-x followed by reset-prompt. 2. Width off by one when a line is broken in the middle of a wide character. Assuming COLUMNS=79, the following prompt has width 2 but countprompt used to return 0. PROMPT="${(pl.40..\u3050.)}" zsh -df Press ctrl-r or type ls<tab> to observe the effects of the bug. 3. Width off by 1-7 when a line is broken in the middle of a tab. Assuming COLUMNS=79, the following prompt has width 1 but countprompt used to return 0. PROMPT="${(pl.10..\t.)}" zsh -df Press Ctrl-R or type ls<TAB> to observe the effects of the bug.
