Implemented `-xattr` on DragonFly BSD + +### Bug fixes + +- Fixed some rarely-used code paths that clean up after allocation failures + +3.1.3 +----- + +**March 6, 2024** + +### Bug fixes + +- On Linux, the `io_uring` feature probing introduced in `bfs` 3.1.2 only applied to one thread, causing all other threads to avoid using io_uring entirely. + The probe results are now copied to all threads correctly. + ([`f64f76b`](https://github.com/tavianator/bfs/commit/f64f76b55400b71e8576ed7e4a377eb5ef9576aa)) + + +3.1.2 +----- + +**February 29, 2024** + +### Bug fixes + +- On Linux, we now check for supported `io_uring` operations before using them, which should fix `bfs` on 5.X series kernels that support `io_uring` but not all of `openat()`/`close()`/`statx()` ([`8bc72d6`](https://github.com/tavianator/bfs/commit/8bc72d6c20c5e38783c4956c4d9fde9b3ee9140c)) + +- Fixed a test failure triggered by certain filesystem types for `/tmp`

[io_uring](https://en.wikipedia.org/wiki/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`](https://github.com/tavianator/bfs/commit/b2ab7a151fca517f4879e76e626ec85ad3de97c7)) + +- Optimized `-exec` by using `posix_spawn()` when possible, which can avoid the overhead of `fork()` ([`95fbde1`](https://github.com/tavianator/bfs/commit/95fbde17a66377b6fbe7ff1f014301dbbf09270d)) + +- `-execdir` and `-okdir` are now rejected if `$PATH` contains a relative path, matching the

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

`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 + +[#107]: https://github.com/tavianator/bfs/pull/107 + + +3.0 +--- + +**July 13, 2023** + +### 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. + +[#101]: https://github.com/tavianator/bfs/issues/101 + +### 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` + +[C17]:

@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` + +[#67]:

+[#91]: https://github.com/tavianator/bfs/issues/91 + + +2.5 +--- + +**March 27, 2022** + +- Added compiler-style context for errors and warnings. + Errors look like this: + + $ bfs -nam needle + bfs:

Fixed regex error reporting bugs + +[#82]: https://github.com/tavianator/bfs/issues/82 + + +2.4 +--- + +**February 22, 2022** + +- 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. + +[#81]:

More tweaks to `PAGER` and `LESS` handling for `bfs -help` ([#76]) + +- Use 512-byte blocks for `-ls` when `POSIXLY_CORRECT` is set ([#77]) + +- Implemented `-files0-from FILE` to take a list of `'\0'`-separated starting paths. + GNU find will implement the same feature in an upcoming release. + +- Added colors to `-printf` output ([#62]) + +- Faster recovery from `E2BIG` during `-exec` +

Fixed some incorrect coloring of broken links when links are being followed (`-L`) + +- Made the tests work when run as root by dropping privileges. + This may be helpful for certain packaging or CI environments, but is not recommended. + +- Treat empty `PAGER` and `LESS` environment variables like they're unset, for `bfs -help` ([#71]). + Thanks @markus-oberhumer! + +- The soft `RLIMIT_NOFILE` is now raised automatically to a fairly large value when possible. + This provides a minor performance benefit for large directory trees. + +- Implemented time units for `-mtime` as found in FreeBSD find ([#75]) + +[#71]: https://github.com/tavianator/bfs/issues/71 +[#75]: https://github.com/tavianator/bfs/issues/75 + + +2.2 +--- + +**March 6, 2021** + +- Fixed `-hidden` on hidden start paths + +- Added a Bash completion script. + Thanks @bmundt6! + +- Fixed rounding in `-used`. + Corresponding fixes were made to GNU find in version 4.8.0. + +- Optimized the open directory representation. + On Linux, much libc overhead is bypassed by issuing syscalls directly. + On all platforms, a few fewer syscalls and open file descriptors will be used. + +- Implemented `-flags` from BSD find + + +2.1 +--- + +**November 11, 2020** + +- Added a new `-status` option that displays the search progress in a bar at the bottom of the terminal + +- Fixed an optimizer bug introduced in version 2.0 that affected some combinations of `-user`/`-group` and `-nouser`/`-nogroup` + + +2.0 +--- + +**October 14, 2020** + +- [#8]: New `-exclude <expression>` syntax to more easily and reliably filter out paths. + For example: + + bfs -name config -exclude -name .git + + will find all files named `config`, without searching any directories (or files) named `.git`. + In this case, the same effect could have been achieved (more awkwardly) with `-prune`: + + bfs ! \( -name .git -prune \) -name config + + But `-exclude` will work in more cases: + + # -exclude works with -depth, while -prune doesn't: + bfs -depth -name config -exclude -name .git + + # -exclude applies even to paths below the minimum depth: + bfs -mindepth 3 -name config -exclude -name .git + +- [#30]: `-nohidden` is now equivalent to `-exclude -hidden`. + This changes the behavior of command lines like + + bfs -type f -nohidden + + to do what was intended. + +- Optimized the iterative deepening (`-S ids`) implementation + +- Added a new search strategy: exponential deepening search (`-S eds`). + This strategy provides many of the benefits of iterative deepening, but much faster due to fewer re-traversals. + +- Fixed an optimizer bug that could skip `-empty`/`-xtype` if they didn't always lead to an action + +- Implemented `-xattrname` to find files with a particular extended attribute (from macOS find) + +- Made `-printf %l` still respect the width specifier (e.g. `%10l`) for non-links, to match GNU find + +- Made `bfs` fail if `-color` is given explicitly and `LS_COLORS` can't be parsed, rather than falling back to non-colored output + +[#8]: https://github.com/tavianator/bfs/issues/8 +[#30]: https://github.com/tavianator/bfs/issues/30 + + +1.* +=== + +1.7 +--- + +**April 22, 2020** + +- Fixed `-ls`

values + + +1.4.1 +----- + +**April 5, 2019** + +- Added a nicer error message when the tests are run as root +- Fixed detection of comparison expressions with signs, to match GNU find for things like `-uid ++10` +- Added support for https://no-color.org/ +- Decreased the number of `stat()` calls necessary in some cases + + +1.4 +--- + +**April 15, 2019** + +- New `-unique` option that filters out duplicate files ([#48]) +- Optimized the file coloring implementation +- Fixed the coloring implementation to match GNU ls more closely in many corner cases + - Implemented escape sequence parsing for `LS_COLORS` + - Implemented `ln=target` for coloring links like their targets + - Fixed the order of fallbacks used when some color keys are unset +- Add a workaround for incorrect file types for bind-mounted files on Linux ([#37]) + +[#48]: https://github.com/tavianator/bfs/issues/48 +[#37]: https://github.com/tavianator/bfs/issues/37 + + +1.3.3 +----- + +**February 10, 2019** + +- Fixed unpredictable behaviour for empty responses to `-ok`/`-okdir` caused by an uninitialized string +- Writing to standard output now causes `bfs` to fail if the descriptor was closed +- Fixed incomplete

+ - Extension colors are now case-insensitive like GNU `ls` + - `or` (orphan) and `mi` (missing) files are now treated differently + - Default colors can be unset with `di=00` or similar + - Specific colors fall back to more general colors when unspecified in more places + - `LS_COLORS` no longer needs a trailing colon +- `-ls`/`-fls` now prints the major/minor numbers for device nodes +- `-exec ;` is rejected rather than segfaulting +- `bfs` now builds on old Linux versions that require `-lrt` for POSIX timers +- For files whose access/change/modification times can't be read, `bfs` no longer fails unless those times are needed for tests +- The testsuite is now more correct and portable + + +1.2.4 +----- + +**September 24, 2018** + +- GNU find compatibility fixes for `-printf`: + - `%Y`
