* Makefile: Rebuild whenever the build flags changeTavian Barnes2020-12-104-2/+17
| | | | | This removes the need to do make clean before rebuilding with a new build type.
* Give messages to unconditional assertion failuresTavian Barnes2020-12-025-6/+6

* util: Use fgetc(stdin) instead of getchar()Tavian Barnes2020-11-301-1/+1
| | | | | On FreeBSD the getchar() macro leads to (spurious?) msan uninitialized value errors. Call the fgetc() library function to work around it.

|
* color: Add an intermediate bufferTavian Barnes2020-11-282-68/+104
| | | | | | | cfprintf() on an unbuffered file like stderr was causing a lot of write() calls since every format specifier resulted in a separate fwrite(). This led to inefficiency and bad interleaving. Add our own dstring buffer to smooth it out.
* dstring: New dstrdcat(), dstrcatf(), dstrvcatf() functionsTavian Barnes2020-11-282-23/+97
|
* eval: Make -hidden behave consistentlyTavian Barnes2020-11-283-1/+19
| | | | | | | | | | | | | | | Previously there was an unexpected difference between $ bfs .hidden -hidden and $ bfs ./.hidden -hidden ./.hidden The intent of the code was to avoid considering `.`, the default starting point, as hidden and thus pruning a whole search with -nohidden. Fix it to do that explicitly, and handle `..` too.

|
* opt: Predicates aren't true when they're falseTavian Barnes2020-11-092-2/+14
| | | | | | | | | | | | This unfortunate typo was mostly harmless; since the predicates were always assumed to be true, they wouldn't conflict. The exception is -user/-group, which set -nouser/-nogroup to false for users/groups that exist. Even -O0 wasn't enough to suppress the bug, due to a missing optlevel check fixed in the previous commit. Fixes: 305ee902874b49351f4916e303c293523f11570b

* spawn: Fix error pipe write failure handlingTavian Barnes2020-11-041-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A short history lesson: this code (from exec.c) used to just be write(...); In 649d85b, an empty if block was added to placate _FORTIFY_SOURCE's warn_unused_result: if (write(...) != sizeof(error)) { // ... } This is fine since the parent doesn't rely on receiving those writes (e.g. the child could die before writing), and the small write to a pipe won't fail anyway. But when bfs_spawn() was created, the implementation changed to this: while (write(...) < sizeof(error)); The while loop was presumably added to mirror musl's posix_spawn() implementation, which handles EINTR. But musl's is actually correct: while (write(...) < 0); whereas mine has a subtle bug: since sizeof(error) is unsigned, the bfs code did an unsigned comparison, meaning -1 from write() would *not* restart the loop. Fix it by comparing with 0 like musl, since short writes are impossible here. Perhaps it's time for -Wsign-compare, despite the other 18 instances being false positives.
