* exec: Fix size accounting when recovering from E2BIGTavian Barnes2018-02-101-4/+6
|
* Release 1.2.11.2.1Tavian Barnes2018-02-083-2/+10
|
* exec: Avoid a warning when building with _FORTIFY_SOURCETavian Barnes2018-02-061-1/+6
| | | | | Also, don't pass the address of errno itself to write(), since write() is allowed to modify it.
* eval: Don't unnecessarily zero fields in struct eval_stateTavian Barnes2018-02-011-7/+6
| | | | | | The designated initializer causes everything not mentioned to be zeroed, a waste of time that shows up on profiles. It also has the potential to hide uninitialized-use bugs.
* bftw: Open-code the "."/".." checksTavian Barnes2018-02-011-3/+4
| | | | | | GCC doesn't (yet) produce very fast code for strcmp() against constant strings (see https://gcc.gnu.org/PR78809), so hand-coding the comparison manually helps significantly.
* bftw: Fix the heap implementationTavian Barnes2018-02-011-1/+21
| | | | | | | | | | There were two problems: - bubble_down() would always bubble the entry all the way down the heap, instead of stopping at the appropriate place - remove() may need to bubble the replacement entry *up* the heap, if it came from a different subtree
* Release 1.21.2Tavian Barnes2018-01-203-2/+16
|
* printf: Add %w and %Wk for file birth timesTavian Barnes2018-01-205-1/+37
| | | | | %w and %W were chosen to match the format specifiers for file birth times from stat(1)
* stat: New wrapper around the stat() familyTavian Barnes2018-01-0815-299/+565
| | | | | This lets bfs transparently support the new statx() system call on Linux, giving it access to file birth times.
* Minor header cleanupsTavian Barnes2018-01-084-9/+12

* parse: Minor cleanups from af7878c/7da0d28Tavian Barnes2018-01-061-6/+2

|
* exec: Make argument size tracking robust to page-granularity accountingTavian Barnes2017-10-261-3/+8
| | | | | | | | From looking at the Linux exec() implementation, it seems a big part of the reason we needed extra headroom was that the arguments/environment are copied page-by-page, so even a small accounting difference could result in an error of an entire page size. Grow the headroom to two entire pages to account for this.
* exec: Apply more headroom to avoid E2BIGTavian Barnes2017-10-221-4/+16
| | | | | | | | | | | | | I ran into "argument list too long" errors with a bfs -type f -exec grep pattern '{}' + command, despite the current accounting being pretty careful. Some experimentation showed that an additional 2048 bytes of headroom is always safe. While we're at it, explicitly account for the terminating NULL pointers in argv and environ.
* Use "error:" prefix consistentlyTavian Barnes2017-10-221-4/+4

* cmdline: Declare functions in a more natural orderTavian Barnes2017-10-211-7/+7

* parse: Keep track of what files are already openTavian Barnes2017-10-216-50/+185
| | | | Fixes #22
* Report errors that occur when closing filesTavian Barnes2017-10-216-11/+60
| | | | Otherwise we miss write errors that occur when flushing the cache.
* Add a man pageTavian Barnes2017-10-153-15/+686
| | | | Fixes #31
* Don't use install -DTavian Barnes2017-10-131-3/+6
| | | | | | -D isn't portable to non-GNU Unices, so just use mkdir manually. Fixes #28

* tests: Silence error messages while creating deep/Tavian Barnes2017-09-091-1/+1
| | | | | Some platforms will print errors like "cannot access parent directories: Result too large"
* Try /proc/self/fd before /dev/fdTavian Barnes2017-09-092-5/+14
| | | | On Solaris, /proc/self/fd is dynamic while /dev/fd is static.
* mtab: Add support for SolarisTavian Barnes2017-09-091-0/+43
|
* Revert "tests: Test hardlinks to symlinks"Tavian Barnes2017-09-0713-20/+0
| | | | | | Apparently macOS doesn't support ln -P. This reverts commit 80eec18020f531abbdb2abbb919ab6c6fa34107c.
* parse: Don't reorder or remove tests with potential side effectsTavian Barnes2017-09-063-3/+29
| | | | | | -empty and -xtype may have side effects like reporting permission errors, which even affect the exit status of bfs. We shouldn't remove these effects without -Ofast.
* util: Factor out checks for nonexistent paths/broken linksTavian Barnes2017-09-063-3/+12
