* bftw: Only rebuild the part of the path that changesTavian Barnes2017-03-221-37/+50
| | | | | | | | | | | | | | Quadratic complexity is still possible for directory structures like root -- a -- a -- a -- a ... | +- b -- b -- b -- b ... But for most realistic directory structures, bfs should now spend less time building paths. (Of course if you print every path, overall complexity is quadratic anyway.)
* bftw: Fix quadratic reference counting complexityTavian Barnes2017-03-201-8/+15
| | | | | | | | | | | | | dircache_entry refcounts used to count every single descendant, resulting in n refcount updates to create/delete an entry at depth n, and thus O(n^2) complexity overall for deep directory structures. Fix it by only counting direct children instead. The cache eviction policy is changed to prefer shallower entries in all cases, attempting to save at least some of the benefit of the previous accounting scheme. Unfortunately, the average number of traversed components for openat() calls still went up by ~20%, but the performance in practice is roughly unchanged in my tests.

* Color link targets for -lsTavian Barnes2017-03-166-26/+60
| | | | Fixes #18.
* Give struct expr a CFILE* instead of just a FILE*Tavian Barnes2017-03-165-58/+90
| | | | This unifies the behaviour of -print and -fprint /dev/stdout.

|
* tests: Don't require bash associative arraysTavian Barnes2017-02-101-22/+11
| | | | That's a bash 4 feature, while macOS is stuck on bash 3.
* bftw: Make the nameoff of "///" point to "/"Tavian Barnes2017-02-096-11/+14
| | | | This simplifies a few things such as -name handling for ///.
* Give the test cases human-readable namesTavian Barnes2017-02-09138-312/+452
|
* Don't close stdin for -ok or -okdirTavian Barnes2017-02-094-15/+45
| | | | Turns out it violates POSIX, even though GNU find does it.
* parse: Factor out all "looks like icmp" checksTavian Barnes2017-02-091-11/+16
|
* bftw: Add the DIR* to bftw_stateTavian Barnes2017-02-091-15/+39
| | | | Can't forget to close it that way.
* Add support for -x?type with multiple typesTavian Barnes2017-02-088-169/+146
| | | | This functionality is already part of GNU findutils git.
* bftw: Add mising closedir() to error pathTavian Barnes2017-02-071-0/+1
|
* Bail out if parse_root() failsTavian Barnes2017-02-071-44/+88
| | | | | | Previously, skip_paths() did not distinguish between end-of-arguments and parse_root() failing, returning NULL in both cases. If parse_root() failed, parsing would attempt to continue, in an unexpected state.
* Add some missing perror() callsTavian Barnes2017-02-073-34/+39
|
* bftw: Plug a leak if dirqueue_push() failsTavian Barnes2017-02-061-16/+28
| | | | | | | | | | If bftw_add() succeeds but dirqueue_push() fails, we need to clean up the just-added dircache_entry. Otherwise it will leak, and we'll also fail the cache->size == 0 assertion. Fix it by extracting the dircache-related parts of bftw_pop() into a new helper function bftw_gc(), and call it from bftw_pop() as well as the bftw_push() failure path.
* Fix a memory leak parsing -printfTavian Barnes2017-02-063-1/+9

|
* Implement -printf/-fprintfTavian Barnes2017-02-0517-46/+1087
| | | | | Based on a patch by Fangrui Song <i@maskray.me>. Closes #16.
* Implement -nouser and -nogroupTavian Barnes2017-02-046-1/+62
|
* Don't trust st_size when reading symlinksTavian Barnes2017-01-313-12/+44
| | | | | Linux /proc, for example, reports a st_size of 0 for everything. It's nice to be able to use -lname on them anyway.
* Simplify exec_chdir()Tavian Barnes2017-01-141-16/+10
| | | | | | The previous code recomputed the name offset for no reason, and had an embarrassing typo that was hypothetically a bug (`} if` instead of `} else if`).
* Don't set _POSIX_C_SOURCETavian Barnes2017-01-061-5/+4
| | | | | | The BSD behaviour is to hide all BSD extensions if standard-conformance feature test macros are present. We don't want strict POSIX, we want all available extensions, so ask for that.

|
* Set _FILE_OFFSET_BITS to 64Tavian Barnes2016-12-213-1/+8
| | | | | With the new support for -size n[TP], this is needed to avoid overflow on 32-bit platforms.

* Don't check errno after get{gr,pw}nam()Tavian Barnes2016-12-201-24/+6
| | | | | Turns out it doesn't always keep errno 0, even if the only problem is a failed lookup. This was observed on a machine with Kerberos auth.
