wcsitype(c, IIDENT) should return false for non-ASCII characters
when the POSIX_IDENTIFIERS option is on, not the other way round.
|
| |
|
|
|
| |
fc with the -L option should ignore remote entires, rather than
reading them and treating them as an error.

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.

If ~/foo does not exist and `zf_mkdir -p zf_mkdir -p` is executed
concurrently in multiple shells, it was possible prior to this patch
for the command to fail with EEXIST.

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.

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.)

To detect an error, set errno to 0 before the call, and check
whether it is nonzero after nice() returns -1.

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.)
