fusefrontend: switch to new go-fuse dir api2025-04-26T09:03:55+00:00Jakob Unterwurzacher2025-03-26T21:45:43+00:00urn:sha1:ae3c859c1179498a4882b4bd69c2243aa6912332
go-fuse 2.6.0, specifically,
https://github.com/hanwen/go-fuse/commit/e885cea8d4d40a5a9bb92bc3cef7193f2a316f59
introduced a new, file-based directory API while
deprecating the old one.
Switch to the new API.
xfstests generic/035 now passes.

go mod: declare module version v22021-08-23T13:05:15+00:00Jakob Unterwurzacher2021-08-23T13:05:15+00:00urn:sha1:69d88505fd7f4cb0d9e4f1918de296342fe05858
Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.
All the import paths have been fixed like this:
find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%

-deterministc-names uses all-zero dirivs but does not write
them to disk anymore.

The new contrib/maxlen.bash showed that we have exponential
runtime with respect to directory depth.
The new recursive diriv caching is a lot smarter as it caches
intermediate lookups. maxlen.bash now completes in a few seconds.

else.

Use the n.prepareAtSyscall() wrapper instead. Prepares
for adding caching into n.prepareAtSyscall().
