2021-08-20Implement -deterministic-names: extended -zerodirivJakob Unterwurzacher
-deterministc-names uses all-zero dirivs but does not write them to disk anymore.
2021-07-31fusefrontend: prepareAtSyscall: handle error when opening ourselvesJakob Unterwurzacher
Error handling was missing here, so we would later get confusing EBADF errors due to dirfd being -1.
2021-06-26fusefrontend: convert last callers from openBackingDir to prepareAtSyscallJakob Unterwurzacher
2021-06-25fusefrontend: implement recursive diriv cachingJakob Unterwurzacher
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. xfstests results same as https://github.com/rfjakob/fuse-xfstests/blob/2d158e4c82be85c15269af77498e353f928f4fab/screenlog.0 : Failures: generic/035 generic/062 generic/080 generic/093 generic/099 generic/215 generic/285 generic/319 generic/426 generic/444 generic/467 generic/477 generic/523 Failed 13 of 580 tests benchmark.bash results are identical: $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.BdQ: gocryptfs v2.0.1-17-g6b09bc0; go-fuse v2.1.1-0.20210611132105-24a1dfe6b4f8; 2021-06-25 go1.16.5 linux/amd64 /tmp/benchmark.bash.BdQ.mnt is a mountpoint WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 0,4821 s, 544 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0,266061 s, 985 MB/s UNTAR: 8,280 MD5: 4,564 LS: 1,745 RM: 2,244
