- drw: minor improvement to the nomatches cache - overhaul utf8decoding and render invalid utf8 sequences as U+FFFD. Thanks NRK for these improvements!

Makefile: remove the options target

2023-09-22T13:13:29Z

The Makefile used to suppress output (by using @), so this target made sense at the time. But the Makefile should be simple and make debugging with less abstractions or fancy printing. The Makefile was made verbose and doesn't hide the build output, so remove this target. Prompted by a question on the mailing list about the options target.

restore SIGCHLD sighandler to default before spawning a program

2023-04-09T10:37:14Z

From sigaction(2): A child created via fork(2) inherits a copy of its parent's signal dispositions. During an execve(2), the dispositions of handled signals are reset to the default; the dispositions of ignored signals are left unchanged. This refused to start directly some programs from configuring in config.h: static Key keys[] = { MODKEY, XK_o, spawn, {.v = cmd } }, }; Some reported programs that didn't start were: mpv, anki, dmenu_extended. Reported by pfx. Initial patch suggestion by Storkman.

config.mk: update to _XOPEN_SOURCE=700L

2023-02-17T14:27:34Z

SA_NOCLDWAIT is marked as XSI in the posix spec [0] and FreeBSD and NetBSD seems to more be strict about the feature test macro [1]. so update the macro to use _XOPEN_SOURCE=700L instead, which is equivalent to _POSIX_C_SOURCE=200809L except that it also unlocks the X/Open System Interfaces. [0]: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/signal.h.html#tag_13_42 [1]: https://lists.suckless.org/dev/2302/35111.html Tested on: * NetBSD 9.3 (fixed). * FreeBSD 13 (fixed). * Void Linux musl. * Void Linux glibc. * OpenBSD 7.2 (stable). * Slackware 11.

Use sigaction(SA_NOCLDWAIT) for SIGCHLD handling

2023-01-28T12:34:43Z

signal() semantics are pretty unclearly specified. For example, depending on OS kernel and libc, the handler may be returned to SIG_DFL (hence the inner call to read the signal handler). Moving to sigaction() means the behaviour is consistently defined. Using SA_NOCLDWAIT also allows us to avoid calling the non-reentrant function die() in the handler. Some addditional notes for archival purposes: * NRK pointed out errno of waitpid could also theoretically get clobbered. * The original patch was iterated on and modified by NRK and Hiltjo: * SIG_DFL was changed to SIG_IGN, this is required, atleast on older systems such as tested on Slackware 11. * signals are not blocked using sigprocmask, because in theory it would briefly for example also ignore a SIGTERM signal. It is OK if waitpid() is (in theory interrupted). POSIX reference: "Consequences of Process Termination": https://pubs.opengroup.org/onlinepubs/9699919799/functions/_Exit.html#tag_16_01_03_01
