* bfstd: Skip a whole loop in dollar_quote() if possibleTavian Barnes2023-09-061-2/+1
|
* bfstd: Fix printable_len() off-by-oneTavian Barnes2023-09-062-2/+17
| | | | | | | If xmbrtowc() fails, or if xiswprint() is false, then we shouldn't include that wide char in the printable length. Fixes: 19c96abe0a1ee56cf206fd5e87defb1fd3e0daa5
* bfstd: Fix an OOB string index in xmbrtowc()Tavian Barnes2023-09-063-6/+24
| | | | | | | | | | | | | | | | | | | | | | This bug could be reproduced with something like $ bfs -samefile $'\xFA\xFA' bfs: error: bfs: dstrnescat@src/dstring.c:252: wordesc() result truncated or worse, with -DNDEBUG, $ bfs -samefile $'.....................\xFA\xFA' bfs: error: bfs -samefile $'.....................\xFA\xFA\x00\x55\x53\x45\x52\x3D\x74\x61\x76\x69\x61\x6E\x61\x74\x6F\x72 bfs: error: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ bfs: error: No such file or directory. which prints the memory after the end of the string (in this case, the environment variable USER=tavianator). The bug was caused by the line `*i += len`, which was intended to be `*i = len`. But actually, the right behaviour seems to be `*i += 1`. Fixes: 19c96abe0a1ee56cf206fd5e87defb1fd3e0daa5
* bftw: Enforce the dirlimit strictlyTavian Barnes2023-09-061-19/+17
| | | | | | The previous accounting didn't fully control the number of allocated bfs_dirs, as the dirlimit was incremented once we popped the directory, not when we freed it.
* bfs uses the C17 standard versionAlejandro Lazaro2023-09-011-1/+1
| | | `bfs` uses C17 since 3.0
* pwcache: Don't use _SC_GET{PW,GR}_R_SIZE_MAXTavian Barnes2023-08-311-23/+9
| | | | | They tend be 1024, which is a lot of memory per user/group. 128 is usually enough, so start there instead.

* Release 3.0.13.0.1Tavian Barnes2023-07-183-2/+20
|
* bftw: Use bftw_file->next for multiple listsTavian Barnes2023-07-181-29/+21
| | | | | A file can be on the to_open and to_read lists at the same time, but otherwise only one list, so we can save memory by sharing the pointers.
* bftw: Use a larger ioq depthTavian Barnes2023-07-181-22/+12
| | | | | | | Now that the dirlimit provides backpressure on the number of open directories, we can use a uniformly larger queue depth for increased performance. The current parameters were tuned with a small grid search on my workstation.
* bftw: Add a queue of directories to unwrapTavian Barnes2023-07-181-7/+22
| | | | | | | | For !BFS_USE_UNWRAPDIR, if a file is still pinned in bftw_closedir(), it has to stay open until its pincount drops to zero. Since this happens in bftw_ioq_pop(), we can't immediately call bftw_unwrapdir() as that adds to the ioq. Instead, add it to a list that gets drained by the next bftw_gc().
* bftw: Add dirs to the end of the queue in bftw_ioq_pop()Tavian Barnes2023-07-181-11/+25
| | | | | | I tried this before in #105 but it led to performance regressions. The key to avoiding those regressions is to put some backpressure on how many bfs_dir's can be allocated simultaneously.
* bftw: Use separate queues for open and closed directoriesTavian Barnes2023-07-171-89/+115
|
* bftw: Check that file->fd == bfs_dirfd(file->dir) earlierTavian Barnes2023-07-171-2/+3
| | | | | | | This has the potential to fail on at least one known platform: macports with the legacysupport implementation of fdopendir(). Link: https://github.com/macports/macports-ports/pull/19047#issuecomment-1636059809
* bftw: Reserve space in the cache before opening filesTavian Barnes2023-07-171-3/+15
| | | | | | | This fixes a storm of EMFILE retries observed with -j1 on a very large directory tree. Fixes: 7888fbababd22190e9f919fc272957426a27969e
* bftw: Pass the whole bftw_state to bftw_openat()Tavian Barnes2023-07-171-510/+451
| | | | | This required shuffling a lot of code around. Hopefully the new order makes more sense.
