* docs: Rename HACKING to CONTRIBUTINGTavian Barnes2023-12-163-8/+8
| | | | So that GitHub recognizes it.

* Revert "README: Realign badges"Tavian Barnes2023-11-281-3/+4
| | | | | | Looks like GitHub fixed their rendering. This reverts commit 3f15559a82484d46942a68e18ba18c7e1c31aab3.

* darray: RemoveTavian Barnes2023-11-234-189/+0
| | | | | The new RESERVE() macro from alloc.h is nicer, and handles alignment properly.
* printf: Switch from darray to RESERVE()Tavian Barnes2023-11-231-175/+195

* mtab: Switch from darray to RESERVE()Tavian Barnes2023-11-231-23/+23

|
* exec: Use the new REALLOC_ARRAY() macroTavian Barnes2023-11-231-1/+1
|
* dstring: Use the new REALLOC_FLEX() macroTavian Barnes2023-11-232-51/+65
| | | | | | While I'm at it, switch the capacity to include the NUL byte, so that it could be used by __counted_by() for example. And fix a theoretical provenance issue.
* alloc: New helpers for aligned reallocationTavian Barnes2023-11-232-4/+62
| | | | | | There is no aligned_realloc(), so the new xrealloc() function emulates it by manually reallocating and copying for over-aligned types. The new REALLOC_ARRAY() and REALLOC_FLEX() macros wrap xrealloc().
* alloc: New ALLOC_MAX macroTavian Barnes2023-11-231-2/+10
|

|
* tests: Fix a possible infinite loopTavian Barnes2023-11-151-2/+4
| | | | | | | | | | | | | | | | | | | The POSIX spec for readdir() [1] says: > If a file is removed from or added to the directory after the most > recent call to opendir() or rewinddir(), whether a subsequent call > to readdir() returns an entry for that file is unspecified. which implies that a loop of readdir()/unlink()/creat() may continue to return new files unendingly. This was even observed on a Linux 6.6 tmpfs mount [2]. It's not clear whether find(1) is also permitted to loop endlessly in this case, but in case it is, let's avoid the whole problem by limiting the -exec to happen at most once.

* eval: Remove Cosmopolitan-specific workaroundTavian Barnes2023-11-131-3/+1
| | | | | | | Turns out this is not specific to Cosmopolitan, it's a recent Linux behaviour change. Link: https://lore.kernel.org/linux-fsdevel/20231113180616.2831430-1-tavianator@tavianator.com/
* tests: Fix --verbose=commands with --bfs="wrapper bfs"Tavian Barnes2023-11-131-1/+1
|
* Revert "bit: Implement a branchless has_single_bit()"Tavian Barnes2023-11-112-2/+2
| | | | | | Doesn't work for the highest bit due to overflow. This reverts commit 208376ef99da243545efcd6fb02d3469b4c068ed.
* Initial support for Cosmopolitan LibcTavian Barnes2023-11-105-3/+33
|
* exec: Don't do setrlimit() in the parentTavian Barnes2023-11-101-22/+4
| | | | | | | | | This was hacky, but it's also broken because it can make posix_spawn() fail with EMFILE, as happens on at least musl. Fixes: 7d69fef6a0b80ad57acde7bac8a22b83531fec0d Link: https://www.austingroupbugs.net/view.php?id=603 Link: https://sourceware.org/bugzilla/show_bug.cgi?id=31049

* list: Simplify slist_remove_impl()Tavian Barnes2023-11-091-4/+4
| | | | We now assume that all-bits-zero is a null pointer, so memset is fine.

|
* parse: Reject -{exec,ok}dir if $PATH contains a relative pathTavian Barnes2023-11-077-0/+32
| | | | This matches the behaviour of GNU find.

|
* xspawn: Do $PATH resolution up-frontTavian Barnes2023-11-071-21/+19
| | | | | | | | | posix_spawnp() is typically implemented like execvp(), i.e., by repeatedly trying execv() with each $PATH component until it succeeds. This is much slower than resolving the executable path up-front and then calling execv() once, so do that. Fixes: https://github.com/tavianator/bfs/pull/127#issuecomment-1795095126
* Treat NO_COLOR="" the same as unsetTavian Barnes2023-11-063-1/+34
| | | | | | | | | | | | | | The docs say > Command-line software which adds ANSI color to its output by default > should check for a NO_COLOR environment variable that, when present > and not an empty string (regardless of its value), prevents the > addition of ANSI color. but we were not checking for the empty string.
