* 47704: POSIX export and readonly ignore "-p" when parameter names also appearBart Schaefer2021-04-182-2/+10

* 48560: add TYPESET_TO_UNSET option to remove initialization of parametersBart Schaefer2021-04-185-7/+36
| | | | | | | | | | Changes typeset such that ${newparam-notset} yields "notset" and "typeset -p newparam" does not show an assignment to the parameter. This is similar to the default behavior of bash and ksh, with minor differences in typeset output. Also add tests for some POSIX incompatibilities plus minor changes for test harness robustness.

* 47794: exec: run final pipeline command in a subshell in sh modebrian m. carlson2021-04-101-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | zsh typically runs the final command in a pipeline in the main shell instead of a subshell. However, POSIX specifies that all commands in a pipeline run in a subshell, but permits zsh's behavior as an extension. The default /bin/sh implementations on various Linux distros and the BSDs always use a subshell for all components of a pipeline. Since zsh may be used as /bin/sh in some cases (such as macOS Catalina), it makes sense to have the common sh behavior when emulating sh, so do that by checking for being the final item of a multi-item pipeline and creating a subshell in that case. From the comment above execpline(), we know the following: last1 is a flag that this command is the last command in a shell that is about to exit, so we can exec instead of forking. It gets passed all the way down to execcmd() which actually makes the decision. A 0 is always passed if the command is not the last in the pipeline. […] If last1 is zero but the command is at the end of a pipeline, we pass 2 down to execcmd(). So there are three cases to consider in this code: • last1 is 0, which means we are not at the end of a pipeline, in which case we should not change behavior. • last1 is 1, which means we are effectively running in a subshell, because nothing that happens due to the exec is going to affect the actual shell, since it will have been replaced. So there is nothing to do here. • last1 is 2, which means our command is at the end of the pipeline, so in sh mode we should create a subshell by forking. input is nonzero if the input to this process is a pipe that we've opened. At the end of a multi-stage pipeline, it will necessarily be nonzero. Note that several of the tests may appear bizarre, since most developers do not place useless variable assignments directly at the end of a pipeline. However, as the function tests demonstrate, there are cases where assignments may occur when a shell function is used at the end of a command. The remaining assignment tests simply test additional cases, such as the use of local, that would otherwise be untested.

| | | | | | The inconsistency caused test failures where TERM is e.g. rxvt-unicode. This also makes a couple of bits available in zattr by removing flags indicating whether to use termcap which is not an attribute as such.

* Allow more scripts without #!Justine Tunney2021-02-161-4/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change modifies the zsh binary safety check surrounding execve() so it can run shell scripts having concatenated binary content. We're using the same safety check as FreeBSD /bin/sh [1]. POSIX was recently revised to require this behavior: "The input file may be of any type, but the initial portion of the file intended to be parsed according to the shell grammar (XREF to XSH 2.10.2 Shell Grammar Rules) shall consist of characters and shall not contain the NUL character. The shell shall not enforce any line length limits." "Earlier versions of this standard required that input files to the shell be text files except that line lengths were unlimited. However, that was overly restrictive in relation to the fact that shells can parse a script without a trailing newline, and in relation to a common practice of concatenating a shell script ending with an 'exit' or 'exec $command' with a binary data payload to form a single-file self-extracting archive." [2] [3] One example use case of such scripts, is the Cosmopolitan C Library [4] which configuse the GNU Linker to output a polyglot shell+binary format that runs on Linux / Mac / Windows / FreeBSD / OpenBSD.

* 47352 (+ extra test cases): fix %<n>K prompt expansionStephane Chazelas2020-09-101-1/+1
| | | | | | | | | | | Fixed a regression introduced by workers/30496 (5.0.3) whereby %2K would no longer be the equivalent of %K{2} (%K{green}) in prompt expansion. That was one missing case where the is_fg flag was not passed along to match_colour() after code factorisation. Add tests for the different syntax variants, using echoti as a reference.
* github #64: Fix a build-time error when building against ncurses that hadn't ↵Daniel Shahaf2020-08-281-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | been built with --enable-wgetch-events. The --enable-wgetch-events codepath is experimental (according to ncurses-6.2/INSTALL) and off by default (according to ncurses-6.2/configure.in). With that codepath disabled, the macro KEY_EVENT is not provided, which (before this commit) manifested as a build-time error: [ 245s] gcc -c -I. -I../../Src -I../../Src -I../../Src/Zle -I. -DHAVE_CONFIG_H -DMODULE -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -Werror=return-type -flto=auto -g -fPIE -D_DEFAULT_SOURCE -D_XOPEN_SOURCE=600 -I/usr/include/ncursesw -fPIC -o curses..o curses.c [ 246s] In file included from curses.c:210: [ 246s] curses_keys.h:93:15: error: 'KEY_EVENT' undeclared here (not in a function); did you mean 'KEY_RESET'? [ 246s] 93 | {"EVENT", KEY_EVENT}, [ 246s] | ^~~~~~~~~ [ 246s] | KEY_RESET curses_keys.h is only used for setting the "kevent" output parameter of 'zcurses input' (and the associated $zcurses_keycodes special variable), so there's no harm in just leaving KEY_EVENT out of it. (That codepath deals gracefully with numeric values that don't correspond to any of the known compile-time values, as that can happen whenever the build- and run-time versions of ncurses don't provide the same set of KEY_* macros, with or without relation to that configure flag.) Reported by Martin Liska.

* 46068 (tweaked) (was: github #57): region_highlight: Add memo= support.Daniel Shahaf2020-06-254-9/+87
| | | | | | | | | | | | | | | | This is useful when multiple plugins add region_highlight entries and subsequently want to remove only their own entries. Without this functionality, recognizing one's region_highlight entries is not trivial because the 'start' and 'end' offsets are modified by editing of $BUFFER and the highlight specification may not be unique or distinctive. The tweaks are as follows: - Change zfree() to zsfree() per workers/46070. - Remove the mem.c hunk, as it changed the signature of only one out of two alternative definitions of zsfree(). (The definition that hunk touched is the one that's not used by default.)
