* bftw: Make sure we don't close a directory while we unwrap itTavian Barnes2023-10-121-2/+6
| | | | | | | bftw_cache_reserve() can lead to bftw_cache_pop(), which could close the directory we're trying to unwrap! If that happened, we would try dup_cloexec(-1), which would fail with EBADF, so there was no observable bug. But it's better to avoid the whole situation.
* bftw: Fix to_close list corruption with !BFS_USE_UNWRAPDIRTavian Barnes2023-10-121-6/+13
| | | | | | | | | | It's possible for pincount to drop to zero, then get incremented and drop back to zero again. If this happens, we shouldn't add it to the to_close list twice. This should fix the intermittent hang on the macOS CI. Fixes: 815798e1eea7fc8dacd5acab40202ec4d251d517

* bftw: Fix unbuffered depth-first searchesTavian Barnes2023-10-121-15/+41
| | | | | | | | | | | | | | | bftw() implements depth-first search by appending files to a batch, then prepending the batch to the queue. When we switched to separate file/ directory queues, this was only implemented for the file queue. Unbuffered searches don't use the file queue, so they were all breadth- first in practice. This meant that iterative deepening (-S ids) was actually "iterative deepening *breadth*-first search," a horrible strategy with no advantage over regular breadth-first search. Now it performs iterative deepening *depth*-first search, which at least limits its memory consumption. Fixes: c1b16b49988ecff17ae30978ea14798d95b80018
