* bfs(1): Fix some double spaces after exclamation marksTavian Barnes2018-12-031-9/+2
|
* exec: Reject -exec \; without a commandTavian Barnes2018-11-142-1/+20
| | | | | | | | | | | 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 {} \;
* tests: Don't assume BSD find has the "implicit ."Tavian Barnes2018-11-141-3/+2
| | | | Also, FreeBSD find rejects -L -delete, so don't test it under --bsd.
* tests: Don't assume find continues after filesystem loopsTavian Barnes2018-11-1419-37/+100
| | | | | | | | | | | POSIX says > When it detects an infinite loop, find shall write a diagnostic > message to standard error and shall either recover its position in the > hierarchy or terminate. So make the 'links' folder not have any loops, and add a new 'loops' folder for testing the GNU/bfs behaviour.

* parse: Use a better reference point for incomplete expression errorsTavian Barnes2018-11-021-1/+8
| | | | | This makes `bfs -not type d` complain about nothing following the `-not` rather than the `d`.

* tests: Move test for -H -newer out of POSIXTavian Barnes2018-09-271-1/+2
| | | | | The POSIX spec implies that -newer is actually not supposed to respect -H/-L. But all implementations I know about do anyway.

| | | | | | | | | | | | Credit to https://github.com/nim-lang/Nim/issues/3138 for the idea to just overwrite environ and call execvp() instead of duplicating the path searching logic.

* util: macOS doesn't have pipe2()Tavian Barnes2018-07-241-1/+2
| | | | | | | The code was testing for BSD, since all the normal BSDs have it. But until recently, <sys/param.h> wasn't included, so BSD was undefined even on platforms that define it. Now that it is defined appropriately, exclude macOS specifically.

* stat: Don't assume blocks are 512 bytesTavian Barnes2018-07-243-6/+24
| | | | | | | | | | | | POSIX says > The unit for the st_blocks member of the stat structure is not defined > within POSIX.1‐2008. and recommends using DEV_BSIZE from <sys/param.h> if available. Also, for -printf '%S', print 1 instead of NaN for empty files with no blocks.

| | | | | Also shorten eval_bfs_stat() to eval_stat(). Looks like this was leftover from an incomplete conversion a while ago.
* eval: Fix -delete when following symlinks.Tavian Barnes2018-07-123-2/+31
| | | | | Same bug as https://savannah.gnu.org/bugs/?46305. Please don't ever do this though.
* stat: Support the glibc statx() wrapperTavian Barnes2018-07-111-6/+18
| | | | | | | | | glibc 2.28 will ship with a wrapper for the statx() system call. Currently the build is broken against it, because sys/stat.h suddenly declares all the same types that linux/stat.h does. Fix it by taking the sys/stat.h ones if they exist. Fixes #35

* exec: Make ARG_MAX accounting a bit less restrictive with large pagesTavian Barnes2018-07-071-3/+6
| | | | | | | | | | | | | | | | | | | 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>
* tests: Use -maxdepth 0 instead of | head -n1Tavian Barnes2018-07-071-1/+1
| | | | | | | This avoids the potential for "broken pipe" errors observed on some systems, e.g. http://build.alpinelinux.org/buildlogs/build-edge-s390x/testing/bfs/bfs-1.2.2-r0.log

* stat: Handle platforms that don't support AT_EMPTY_PATH for fstatat()Tavian Barnes2018-07-021-3/+12
| | | | | | | | In particular, this caused -fprint to break on Hurd since AT_EMPTY_PATH is defined and works for some syscalls but not fstatat(). Should fix: https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=hurd-i386&ver=1.2.2-1&stamp=1529920401&raw=0
* stat: Don't try to statx() on architectures without the syscallTavian Barnes2018-07-021-2/+2
| | | | | | | | | | Turns out that ia64 and sh4 define all the structures and constants, but don't actually support the statx() system call itself. So instead of testing for the constants, just test for the syscall number directly. Should fix: https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=ia64&ver=1.2.2-1&stamp=1529917943&raw=0 https://buildd.debian.org/status/fetch.php?pkg=bfs&arch=sh4&ver=1.2.2-1&stamp=1529917893&raw=0
