* | bftw: Enforce the dirlimit strictly | Tavian Barnes | 2023-09-06 | 1 | -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. | ||||
* | bftw: Use bftw_file->next for multiple lists | Tavian Barnes | 2023-07-18 | 1 | -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 depth | Tavian Barnes | 2023-07-18 | 1 | -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 unwrap | Tavian Barnes | 2023-07-18 | 1 | -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 Barnes | 2023-07-18 | 1 | -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 directories | Tavian Barnes | 2023-07-17 | 1 | -89/+115 |

* | bftw: Check that file->fd == bfs_dirfd(file->dir) earlier | Tavian Barnes | 2023-07-17 | 1 | -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 files | Tavian Barnes | 2023-07-17 | 1 | -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 Barnes | 2023-07-17 | 1 | -510/+451 |
| | | | | | This required shuffling a lot of code around. Hopefully the new order makes more sense. | ||||
