* dstring: Add an infallible dstrshrink() functionTavian Barnes2024-10-171-2/+2
| | | | And mark the fallible ones with _nodiscard.
* eval: Use xtimer_start() for status bar updatesTavian Barnes2024-10-101-36/+76

* Fix includesTavian Barnes2024-08-291-0/+1

* build: Move feature test macros to prelude.hTavian Barnes2024-08-281-1/+0
| | | | | | This replaces the explicit CPPFLAGS list in flags.mk with just `-include src/prelude.h`, shortening our compiler command lines and allowing them to be easily documented.
* prelude: Split bfs-specific utilities into new bfs.h headerTavian Barnes2024-08-281-0/+3

* New -noerror option to suppress error messagesTavian Barnes2024-08-161-1/+16
| | | | Closes: https://github.com/tavianator/bfs/issues/142

* bfstd: New sysoption() macro to check for POSIX option runtime supportTavian Barnes2024-08-091-4/+7
| | | | | | | | | | POSIX allows optional features to be supported at compile time but not necessarily at run time by defining _POSIX_OPTION to 0 and requiring users to check sysconf(_SC_OPTION) > 0. The new sysoption() macro simplifies the check. sighook() and bfs_spawn() now check for conditional runtime support for the relevant POSIX options.
* xtime: Remove xgettime()Tavian Barnes2024-08-091-12/+7
| | | | clock_gettime() is available everywhere by now.

| * Make ELOOP an error again, except for -xtype.3.3.1Tavian Barnes2024-06-031-0/+7
| | | | | | | | | | | | | | | | | | | | POSIX requires an error if (for example) -L encounters a symlink loop. The GNU find change was restricted to -xtype, so add a manual ELOOP test to eval_xtype() for compatibility. This reverts commit 470589cbd9ca3e73d8c01ac3a96cbc065179dcc5.

* eval: Don't turn on NOKERNINFOTavian Barnes2024-05-271-95/+8
| | | | | Other utilities on FreeBSD like dd, sleep, etc. that respond to SIGINFO still print the kernel info line too.
* eval: Use a flag instead of a counter for SIGINFOTavian Barnes2024-05-271-16/+13

* opt: Don't raise RLIMIT_NOFILE if it would prevent using posix_spawn()Tavian Barnes2024-05-231-0/+3
| | | | | | | | | | If we raise RLIMIT_NOFILE, we have to lower it before calling exec() for compatibility with select(). If posix_spawn() doesn't support that, we fall back to fork(), which is quite a bit slower. Therefore, if we're going to exec() on most files, it's better to keep RLIMIT_NOFILE the same to avoid the fork() cost, even though it makes bftw() somewhat slower.
* expr: New for_expr macroTavian Barnes2024-05-231-5/+5

* Stop using %mTavian Barnes2024-05-201-11/+9
|
* Cast AT_FDCWD to int for comparisonsTavian Barnes2024-05-171-1/+1
| | | | | Some platforms define AT_FDCWD to a constant like 0xFFFAFDCD that gets typed as an unsigned int.
* eval: Plug memory leak if bfs_opendir() failsTavian Barnes2024-04-241-18/+22

* xtime: Call tzset() from main() instead of lazilyTavian Barnes2024-03-071-1/+1
| | | | | | | | | | | | | POSIX specifies[1] that If a thread accesses tzname, daylight, or timezone directly while another thread is in a call to tzset(), or to any function that is required or allowed to set timezone information as if by calling tzset(), the behavior is undefined. So calling it lazily from arbitrary threads is risky. [1]: https://pubs.opengroup.org/onlinepubs/9699919799/functions/tzset.html

* sanity: Don't use self-init for uninit()Tavian Barnes2024-02-121-1/+1
| | | | | | | | | | | Self-initialization like bool ret = ret; is a GCC trick to suppress uninitialized variable warnings, but it's not actually well-defined, and will trip a recent enough MemorySanitizer: src/eval.c:1088:13: runtime error: load of value 128, which is not a valid value for type 'bool'

|
* bfstd: New {error,errno}_is_like() functionsTavian Barnes2024-01-131-1/+1
| | | | | | | We used to have is_nonexistence_error() to consistently treat ENOENT and ENOTDIR the same. Recently, we started considering EFAULT the same as ENAMETOOLONG on DragonFly BSD to work around a kernel bug. Unify both of these behind a more generic interface.
* eval: Check for xbasename() allocation failureTavian Barnes2024-01-071-1/+8
|
* expr: Make expressions variadicTavian Barnes2024-01-071-31/+24
| | | | | | | | | Rather than only unary/binary expressions, we now support an arbitrary number of children. The optimizer has been re-written almost completely and now supports optimal reordering of longer expression chains, rather than just arm-swapping. Fixes #85.
