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!

Version 2.6

• Fixed deleting large NFS directories on FreeBSD (#67).

• Added support for a bfs-specific BFS_COLORS environment variable.

• Refactored the build system, directory structure, and documentation (#88, #89, #91). Thanks @ElectronicsArchiver!

• Added zsh completion (#86). Thanks @VorpalBlade!

• Updated the default color scheme to match GNU coreutils 9.1. Files with capabilities set are no longer colored differently by default, resulting in a significant performance improvement.

• Became less aggressive at triggering automounts

• Added support for out-of-tree builds with BUILDDIR

Version 2.5

• Added compiler-style context for errors and warnings. Errors look like this:

  $ bfs -nam needle
  bfs: error: bfs -nam needle
  bfs: error:     ~~~~
  bfs: error: Unknown argument; did you mean -name?
  

  and warnings look like this:

  $ bfs -print -name 'needle'
  bfs: warning: bfs -print -name needle
  bfs: warning:            ~~~~~~~~~~~~
  bfs: warning: The result of this expression is ignored.
  

• Updated from C99 to C11

• Fixed the tests when built against musl

• Fixed a build error reported on Manjaro

Version 2.4.1

• Fixed the build when Oniguruma is not installed in the default search paths (#82)

• Fixed string encoding bugs with Oniguruma enabled

• Fixed regex error reporting bugs

Version 2.4

• Added the Oniguruma regular expression library as an (optional, but enabled by default) dependency (#81). Oniguruma supports more regular expression syntax types than the POSIX regex API, and often performs better. To build bfs without this new dependency, do make WITH_ONIGURUMA= to disable it. Thanks @data-man!

• Added support for the ed, emacs, grep, and sed regular expression types (#21)

• Before executing a process with -exec[dir]/-ok[dir], bfs now ensures all output streams are flushed. Previously, I/O from subprocesses could be interleaved unpredictably with buffered I/O from bfs itself.

Version 2.3.1

• Fixed the build on Debian kFreeBSD

• Fixed a crash on GNU Hurd when piping bfs's output

• Fixed a double-close() on non-Linux platforms if fdopendir() fails

• Reduced memory allocations on startup
