2.* === 2.6.1 ----- **July 7, 2022** - Fix `stat()` errors on GNU Hurd systems with glibc older than 2.35 - Added fish shell tab completion ([#94]). Thanks @xfgusta! [#94]: https://github.com/tavianator/bfs/pull/94 2.6 --- **May 21, 2022** - 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` [#67]: https://github.com/tavianator/bfs/issues/67 [#86]: https://github.com/tavianator/bfs/issues/86 [#88]: https://github.com/tavianator/bfs/issues/88 [#89]: https://github.com/tavianator/bfs/issues/89 [#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: 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 2.4.1 ----- **February 24, 2022** - 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 [#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]: https://github.com/tavianator/bfs/pull/81 [#21]: https://github.com/tavianator/bfs/issues/21 2.3.1 ----- **January 21, 2022** - 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 2.3 --- **November 25, 2021** - 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` [#76]: https://github.com/tavianator/bfs/issues/76 [#77]: https://github.com/tavianator/bfs/issues/77 [#62]: https://github.com/tavianator/bfs/issues/62 2.2.1 ----- **June 2, 2021** - 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` printing numeric IDs instead of user/group names in large directory trees - Cached the user and group tables for a performance boost - Fixed interpretation of "default" ACLs - Implemented `-s` flag to sort results 1.6 --- **February 25, 2020** - Implemented `-newerXt` (explicit reference times), `-since`, `-asince`, etc. - Fixed `-empty` to skip special files (pipes, devices, sockets, etc.) 1.5.2 ----- **January 9, 2020** - Fixed the build on NetBSD - Added support for NFSv4 ACLs on FreeBSD - Added a `+` after the file mode for files with ACLs in `-ls` - Supported more file types (whiteouts, doors) in symbolic modes for `-ls`/`-printf %M` - Implemented `-xattr` on FreeBSD 1.5.1 ----- **September 14, 2019** - Added a warning to `-mount`, since it will change behaviour in the next POSIX revision - Added a workaround for environments that block `statx()` with `seccomp()`, like older Docker - Fixed coloring of nonexistent leading directories - Avoided calling `stat()` on all mount points at startup 1.5 --- **June 27, 2019** - New `-xattr` predicate to find files with extended attributes - Fixed the `-acl` implementation on macOS - Implemented depth-first (`-S dfs`) and iterative deepening search (`-S ids`) - Piped `-help` output into `$PAGER` by default - Fixed crashes on some invalid `LS_COLORS` 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 file coloring in error messages - Added some data flow optimizations - Fixed `-nogroup`/`-nouser` in big directory trees - Added `-type w` for whiteouts, as supported by FreeBSD `find` - Re-wrote the `-help` message and manual page 1.3.2 ----- **January 11, 2019** - Fixed an out-of-bounds read if LS_COLORS doesn't end with a `:` - Allowed multiple debug flags to be specified like `-D opt,tree` 1.3.1 ----- **January 3, 2019** - Fixed some portability problems affecting FreeBSD 1.3 --- **January 2, 2019** New features: - `-acl` finds files with non-trivial Access Control Lists (from FreeBSD) - `-capable` finds files with capabilities set - `-D all` turns on all debugging flags at once Fixes: - `LS_COLORS` handling has been improved: - 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` now prints `?` if an error occurs resolving the link - `%B` is now supported for birth/creation time (as well as `%W`/`%w`) - All standard `strftime()` formats are supported, not just the ones from the GNU find manual - Optimizations are now re-run if any expressions are reordered - `-exec` and friends no longer leave zombie processes around when `exec()` fails 1.2.3 ----- **July 15, 2018** - Fixed `test_depth_error` on filesystems that don't fill in `d_type` - Fixed the build on Linux architectures that don't have the `statx()` syscall (ia64, sh4) - Fixed use of AT_EMPTY_PATH for fstatat on systems that don't support it (Hurd) - Fixed `ARG_MAX` accounting on architectures with large pages (ppc64le) - Fixed the build against the upcoming glibc 2.28 release that includes its own `statx()` wrapper 1.2.2 ----- **June 23, 2018** - Minor bug fixes: - Fixed `-exec ... '{}' +` argument size tracking after recovering from `E2BIG` - Fixed `-fstype` if `/proc` is available but `/etc/mtab` is not - Fixed an uninitialized variable when given `-perm +rw...` - Fixed some potential "error: 'path': Success" messages - Reduced reliance on GNU coreutils in the testsuite - Refactored and simplified the internals of `bftw()` 1.2.1 ----- **February 8, 2018** - Performance optimizations 1.2 --- **January 20, 2018** - Added support for the `-perm +7777` syntax deprecated by GNU find (equivalent to `-perm /7777`), for compatibility with BSD finds - Added support for file birth/creation times on platforms that report it - `-Bmin`/`-Btime`/`-Bnewer` - `B` flag for `-newerXY` - `%w` and `%Wk` directives for `-printf` - Uses the `statx(2)` system call on new enough Linux kernels - More robustness to `E2BIG` added to the `-exec` implementation 1.1.4 ----- **October 27, 2017** - Added a man page - Fixed cases where multiple actions write to the same file - Report errors that occur when closing files/flushing streams - Fixed "argument list too long" errors with `-exec ...
