3.1.1

Changes

• Performance and scalability improvements

• The file count in bfs -status now has a thousands separator

Version 3.1

New features

• On Linux, bfs now uses io_uring for async I/O

• On all platforms, bfs can now perform stat() calls in parallel, accelerating queries like -links, -newer, and -size, as well as colorized output

• On FreeBSD, -type w now works to find whiteouts like the system find

Changes

• Improved bfs -j2 performance (b2ab7a1)

• Optimized -exec by using posix_spawn() when possible, which can avoid the overhead of fork() (95fbde1)

• -execdir and -okdir are now rejected if $PATH contains a relative path, matching the behaviour of GNU find (163baf1)

• Leading whitespace is no longer accepted in integer command line arguments like -links ' 1' (e0d7dc5)

Bug Fixes

• -quit and -exit could be ignored in the iterative deepening modes (-S {ids,eds}). This is now fixed (670ebd9). The bug was introduced in version 3.0.3 (commit 5f16169).

• Fixed two possible errors in sort mode (-s):

  • Too many open files (710c083)
  • Out of memory (76ffc8d)

• Fixed handling of FreeBSD union mounts (3ac3bee)

• Fixed NO_COLOR handling when it's set to the empty string (79aee58)

• Fixed some portability issues:

  • OpenBSD
  • NetBSD
  • DragonFly BSD
  • Illumos

Version 3.0.4

Bug Fixes

• Fixed a segfault when reporting errors under musl (d40eb87)

Version 3.0.3

Changes

• Iterative deepening modes (-S {ids,eds}) were optimized by delaying teardown until the very end (5f16169)

• Parallel depth-first search (-S dfs) was optimized to avoid enqueueing every file separately (2572273)

Bug Fixes

• Iterative deepening modes (-S {ids,eds}) were performing iterative breadth-first searches since bfs 3.0, negating any advantages they may have had over normal breadth-first search. They now do iterative depth-first searches as expected. (a029d95)

• Fixed a linked-list corruption that could lead to an infinite loop on macOS and other non-Linux, non-FreeBSD platforms (773f4a4)

Version 3.0.2

Changes

• -files0-from now allows an empty set of paths to be given, matching GNU findutils 4.9.0

• Reduced memory consumption in multi-threaded searches

• Many man page updates

Bug fixes

• Fixed an out-of-bounds memory read that could occur when escaping a string containing an incomplete multi-byte character

Version 3.0.1

Bug fixes

• Traversal fixes that mostly affect large directory trees (#107)

  • bfs could encounter EMFILE, close a file, and retry many times, particularly with -j1

  • Breadth-first search could become highly unbalanced, negating many of the benefits of bfs

  • On non-{Linux,FreeBSD} plaforms, directories could stay open longer than necessary, consuming extra memory

Version 3.0

New features

• bfs now reads directories asynchronously and in parallel (#101). Performance is significantly improved as a result. Parallelism is controlled by the new -j flag, e.g. -j1, -j2, etc.

Changes

• bfs now uses the C17 standard version, up from C11

• Due to #101, bfs now requires some additional C and POSIX features:

  • Standard C atomics (<stdatomic.h>)
  • POSIX threads (<pthread.h>)

• $LS_COLORS extensions written in different cases (e.g. *.jpg=35:*.JPG=01;35) are now matched case-sensitively, to match the new behaviour of GNU ls since coreutils version 9.2

• Added a warning/error if $LS_COLORS can't be parsed, depending on whether -color is requested explicitly

• Filenames with control characters are now escaped when printing with -color

• Build flags like WITH_ONIGURUMA have been renamed to USE_ONIGURUMA

Bug fixes

• Fixed handling of the "normal text" color (no in $LS_COLORS) to match GNU ls

Version 2.6.3

• Fixed running the tests as root on Linux 8b24de3

• Fixed some tests on Android 2724dfb 0a5a80c

• Stopped relying on non-POSIX touch(1) features in the tests. This should fix the tests on at least OpenBSD. 2d5edb3

• User/group caches are now filled lazily instead of eagerly b41dca5

• More caches and I/O streams are flushed before -exec/-ok f98a1c4

• Fixed various memory safety issues found by fuzzing
  712b137 5ce883d da02def c55e855

• Fixed a test failure on certain macOS versions 8b24de3

• Mitigated a race condition when determining filesystem types (#97)

• Lots of refactoring and optimization

Version 2.6.2

• Fixed use of uninitialized memory on parsing errors involving -fprintf

• Fixed Android build issues (#96)

• Refactored the test suite

Version 2.6.1

• Fix stat() errors on GNU Hurd systems with glibc older than 2.35

• Added fish shell tab completion (#94). Thanks @xfgusta!
