* expr: Get rid of the extra list nodeTavian Barnes2024-11-044-11/+5
| | | | We can now just use for_arena() to iterate over the allocated bfs_exprs.

* alloc: Switch arenas from a freelist to a bitmap allocatorTavian Barnes2024-11-042-90/+262

* alloc: Don't require the old size in varena_realloc()Tavian Barnes2024-11-028-43/+69
| | | | Instead, just look up which arena contains the pointer.
* sanity: Don't mark memory uninit in sanitize_{alloc,free}()Tavian Barnes2024-11-023-19/+45
| | | | | We might want to change the size of an allocated region without changing which bytes are initialized.
* alloc: Stop supporting pathological flexible array ABIsTavian Barnes2024-11-023-22/+29

* alloc: Add macro versions of alignment utilsTavian Barnes2024-11-021-3/+12
|
* trie: Fix varena_free() with wrong sizeTavian Barnes2024-11-021-8/+8
| | | | | | | In trie_remove(), clearing the bit before trie_node_collapse() causes us to free the old node with size 1 instead of 2, putting it on the wrong freelist. This is technically safe with the current arena implementation, but not intentional.
* alloc: Don't require size % align == 0Tavian Barnes2024-11-025-39/+27
| | | | | | | | | Allowing unaligned sizes will allow us to allocate aligned slabs with additional metadata in the tail without ballooning the allocation size for large alignments.

* Merge pull request #146 from jody-frankowski/fix/capa-color-non-linuxTavian Barnes2024-10-315-1/+43
|\ | | | | Fix bfs coloring all files as if they had a capability, on non-Linux systems
| * color: Handle bfs_check_capabilities error code (-1) in cpath_has_capabilitiesJody Frankowski2024-10-315-1/+43
|/ | | | | | | | | | | On non-Linux systems, bfs_check_capabilities always returned -1, so cpath_has_capabilities would always return true. If bfs was called with an LS_COLORS containing the `ca` statement, e.g. `ca=30;41`, bfs would color ALL the files. While including the `ca` statement in LS_COLORS on non-Linux systems is unusual, this is not an error and is a valid use-case (e.g. Using GNU ls or lsd). Fixes: 1520d4d3 ("color: Don't color files like directories on ENOTDIR")
* bit: Add bswap() overloads for every primitive typeTavian Barnes2024-10-272-9/+41

* color: Fix an infinite loop colorizing some invalid pathsTavian Barnes2024-10-133-8/+13
| | | | | | | | | | | | | | Previously, given $ touch file $ ln -s file/file notdir $ bfs notdir/file bfs would loop forever when printing the error message, since it expected stripping the trailing slash from "notdir/" to fix the ENOTDIR error, but the broken symlink still gave the same error. Fixes: b4c3201 ("color: Only highlight the trailing slash on ENOTDIR")

* xtime: Add a wrapper for timer_create()/setitimer()Tavian Barnes2024-10-104-0/+130
| | | | | | setitimer() is obsolescent in POSIX 2008 and removed from POSIX 2024. However, at least macOS doesn't implement the new timer_create() API, so we still need the setitimer() fallback.

* trie: Switch the tag bits aroundTavian Barnes2024-10-081-31/+28
| | | | | | First of all, almost all checks were !trie_is_leaf(), so it makes sense to use trie_is_node() instead. Secondly, using the tag bit for internal nodes allows us to remove some NULL checks.

* color: Fix an assertion failure with embedded NUL bytesTavian Barnes2024-10-023-0/+42
| | | | | | | | | | | | | Leading NUL bytes (e.g. `*\0.gz=...`) could cause us to insert a non-prefix-free set of strings into the case-insensitive extension trie, which would lead to crashes like bfs: trie_split@src/trie.c:538: Assertion failed: `key_nibble != rep_nibble` and OOB accesses to trie leaf keys. Fix it by ignoring those extensions, since filenames cannot contain NUL bytes. Fixes: 08030aea ("color: Delay the case_sensitive decision")

| | | | | | | | | | | | | | | | Since commit 3552b79 ("build/flags: Infrastructure to detect compiler flag support"), this file only listed a bunch of lines like -include obj/src/alloc.d -include obj/src/bar.d ... We can do that just as well from the main Makefile, and in one line too: -include ${OBJS:.o=.d} This lets us pull the list of all objects out of build/prelude.mk and put it closer to where those objects are actually used.
