* Fix compilation on MS-Windowsscratch/posix-spawn-no-gnulibEli Zaretskii2020-12-311-0/+2
| | | | | * src/callproc.c (emacs_spawn) <fork_done>: Define the label only if USABLE_POSIX_SPAWN is defined, to avoid a compiler warning.
* Use posix_spawn if possible.Philipp Stephani2020-12-302-1/+205
| | | | | | | | | | | | | | | | | posix_spawn is less error-prone than vfork + execve, and can make better use of system-specific enhancements like 'clone' on Linux. Use it if we don't need to configure a pseudoterminal. * configure.ac (HAVE_SPAWN_H, HAVE_POSIX_SPAWN) (HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR) (HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR_NP) (HAVE_POSIX_SPAWNATTR_SETFLAGS, HAVE_DECL_POSIX_SPAWN_SETSID): New configuration variables. * src/callproc.c (USABLE_POSIX_SPAWN): New configuration macro.

* Robustify completion match scoring for optimized patternsJoão Távora2020-12-281-21/+27
| | | | | | | | | | | | | | | | | | | | | | | | Fixes: bug#42149 The function completion-pcm--hilit-commonality, which propertizes and scores a previously confirmed match, expected its PATTERN argument to match the strings of COMPLETIONS entirely (i.e. up to the string's very end). But sometimes the ending wildcard, represented by the 'any' atom in PATTERN, is optimized away by completion-pcm--optimize-pattern. Although this is mostly benign in terms of highlighting commonality, it leads to incorrect score values. In this change, we ensure that completion-pcm--hilit-commonality is aware of this exception and isn't affected by it. We also document the function a bit better and simplify its workings. Originally reported by Dario Gjorgjevski <dario.gjorgjevski@gmail.com> * lisp/minibuffer.el (completion-pcm--hilit-commonality): Simplify. Add docstring. * lisp/minibuffer.el (completion-pcm--hilit-commonality): Add docstring

* * lisp/minibuffer.el: Avoid consecutive `any` in completion patternsStefan Monnier2020-12-281-1/+2
