2019-07-05	exec: Mark a formatting function as BFS_FORMATTER	Tavian Barnes

2019-06-16	exec: Assert that at_fd is the immediate parent	Tavian Barnes

2019-01-02	diag: Unify diagnostic formatting	Tavian Barnes
	This adds a bfs: prefix to error/warning messages for consistency with other command line tools, and leaves only the "error:"/"warning:" part colored like GCC. It also uniformly adds full stops after messages.
2018-11-14	exec: Reject -exec \; without a command	Tavian Barnes
	Prior to this, we'd fork and then segfault on every file as NULL was passed to execvpe(). Found while looking through old FreeBSD find bugs: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=36521 bfs still supports the (dubious, possibly unintentional?) GNU find extension to POSIX that allows $ bfs -exec {} \;
2018-09-18	spawn: New posix_spawn()-like API for exec	Tavian Barnes

2018-09-12	exec: Don't leave zombies around if the child fails to exec()	Tavian Barnes

2018-09-10	exec: More fixes for bfs_exec_debug() changing errno	Tavian Barnes

2018-07-08	exec: Add some debugging info about failed commands	Tavian Barnes

2018-07-07	exec: Make ARG_MAX accounting a bit less restrictive with large pages	Tavian Barnes
	For Linux-style accounting, we really only need to handle a single page of wasted space due to rounding. Subtracting two pages for extra headroom was reasonable on systems with 4K pages, but overkill on systems like ppc64le with 64K pages. Worse yet was the fact that Alpine Linux only gives us 128K for arguments. Instead, only subtract a single page, plus the POSIX-recommended 2048 bytes. Credit to Mike Sullivan for the initial patch and testing on Alpine ppc64le. Fixes: http://build.alpinelinux.org/buildlogs/build-edge-ppc64le/testing/bfs/bfs-1.2.2-r0.log Co-authored-by: Mike Sullivan <mksully22@gmail.com>
2018-06-25	exec: Don't assume bfs_exec_debug() doesn't change errno	Tavian Barnes

2018-02-10	exec: Fix size accounting when recovering from E2BIG	Tavian Barnes

2018-02-06	exec: Avoid a warning when building with _FORTIFY_SOURCE	Tavian Barnes
	Also, don't pass the address of errno itself to write(), since write() is allowed to modify it.
2017-11-13	exec: Minor whitespace consistency fix	Tavian Barnes

2017-11-12	exec: Recover from E2BIG	Tavian Barnes

2017-10-26	exec: Make argument size tracking robust to page-granularity accounting	Tavian Barnes
	From looking at the Linux exec() implementation, it seems a big part of the reason we needed extra headroom was that the arguments/environment are copied page-by-page, so even a small accounting difference could result in an error of an entire page size. Grow the headroom to two entire pages to account for this.
2017-10-22	exec: Apply more headroom to avoid E2BIG	Tavian Barnes
	I ran into "argument list too long" errors with a bfs -type f -exec grep pattern '{}' + command, despite the current accounting being pretty careful. Some experimentation showed that an additional 2048 bytes of headroom is always safe. While we're at it, explicitly account for the terminating NULL pointers in argv and environ.
2017-09-16	opt: Separate optimization from parsing	Tavian Barnes

2017-07-29	exec: Fix more corner cases with -ok ... +	Tavian Barnes
	-ok should look for a ; even if it sees {} +, according to POSIX.
2017-07-29	exec: Don't allow anything between {} and +	Tavian Barnes
	POSIX explicitly forbids this extension: > Only a <plus-sign> that immediately follows an argument containing > only the two characters "{}" shall punctuate the end of the primary > expression. Other uses of the <plus-sign> shall not be treated as > special.
2017-07-29	util: Define O_DIRECTORY to 0 if it's not already defined	Tavian Barnes

2017-07-27	Re-license under the BSD Zero Clause License	Tavian Barnes

2017-07-15	Handle yes/no prompts correctly according to the locale	Tavian Barnes

2017-07-08	exec: Clear errno when a multi-exec doesn't fail	Tavian Barnes
	This fixes strange "Inappropriate ioctl for device" errors when using -exec ... + with output redirection. errno was set to ENOTTY by the isatty() call during startup for color auto-detection, and never cleared before eval_exec() wants to check if anything went wrong.
2017-05-09	Implement -D exec	Tavian Barnes

2017-04-30	exec: Treat -1 from _SC_ARG_MAX as "unlimited"	Tavian Barnes

2017-04-15	exec: Interpret ARG_MAX corretly.	Tavian Barnes
	Thanks to https://www.in-ulm.de/~mascheck/various/argmax/
2017-04-15	exec: close() the working directory even if !ftwbuf	Tavian Barnes

2017-04-15	Implement -exec/-execdir ... +	Tavian Barnes
