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** +

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 ...
