* 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.
