2020-07-12v2api: properly implement Node.SetattrJakob Unterwurzacher
We used to always open a *File2 and letting the *File2 handle Setattr. This does not work it we cannot open the file!

2020-07-12v2api: Getattr: fix file sizeJakob Unterwurzacher
2020-07-12v2api: call InitSerializerJakob Unterwurzacher
If we don't, reads hang with -serialize_reads.
2020-07-12v2api: fix Rename trying to overwrite itselfJakob Unterwurzacher
We used to do this [pid 99182] renameat2(14, "Y_4DAxKvj1QnXmJx2AkrKA", 15, ".", RENAME_NOREPLACE <unfinished ...> which was not the intention.

2020-06-21v2api (go-fuse v2 api): initial noop implementationJakob Unterwurzacher
Compiles and mounts but does nothing useful.
2020-05-24Revert "fusefrontend: don't always clear the dircache in Rename"Jakob Unterwurzacher
As noticed by @slackner in https://github.com/rfjakob/gocryptfs/commit/cb8872577d66ff0fc38bcd70493be06bc0f34ffa#commitcomment-39405233 , this is not safe. This reverts commit cb8872577d66ff0fc38bcd70493be06bc0f34ffa.
2020-05-24fusefrontend: don't always clear the dircache in RenameJakob Unterwurzacher
When filename encryption is on, we do know when we overwrite a directory, and can clear only in this case. sshfs-benchmark.bash: sshfs gocryptfs-on-sshfs git init 1.74 7.80 rsync 6.19 11.63
2020-05-24fusefrontend: don't clear dircache on MkdirJakob Unterwurzacher
Mkdir can not cause existing entries in the cache to go stale. So don't clear it. Benchmark results: sshfs-benchmark.bash: sshfs gocryptfs-on-sshfs git init 1.65 8.74 rsync 6.09 17.54
2020-05-17dircache: increase cache size & lifetimeJakob Unterwurzacher
Looking at the dircache debug output, we see that a "git status" workload has a very bad cache hit rate because the entries expire or get evicted before they can be reused. Increase both cache size and lifetime for a 4x speedup: Before: 75s After: 17s https://github.com/rfjakob/gocryptfs/issues/410
