      mount: add Options{RootStableAttr} field · 615a0a7e
      ZheNing Hu authored
      - provides an optional way to set e.g. Ino and/or Gen for
        the root directory when calling fs.Mount()
      - provides unit test cases
      - partial fix for #399

      Commit

      This will be important for DirectMount, as passing "fsname=xxx" to

      fuse, fs: add DirectMount tests & DirectMountStrict option · 05c0aea6
      Jakob Unterwurzacher authored
      Reason for adding DirectMountStrict is making the DirectMount
      functionality testable, though it may have value for the user
      in some cases.
      
      Add defaultRawFileSystem & loopback tests for DirectMount
      and DirectMountStrict.
      
      The tests fail right now due to bugs in DirectMount that will be fixed
      shortly:

      fuse: Increase MAX_KERNEL_WRITE to 1 MiB & enable CAP_MAX_PAGES · 265a3926
      Jakob Unterwurzacher authored
      Kernel 4.20 allows writes & reads up to 1 MiB (before: 128 kiB)
      via CAP_MAX_PAGES & MaxPages.
      
      Instead of exposing MaxPages in the API, we follow what libfuse
      does, and calculate MaxPages from MaxWrite (rounding up).
      
      Contrary to what libfuse does, we also set max_read to the same
      value as MaxWrite. This prevents reads getting larger than writes
      due to the rounding-up for MaxPages, which is unexpected. This
      also changes the default behavoir of go-fuse, which was 64 kiB
      writes, but 128 kiB for reads. Now it is 128 kiB for both.
      
      The tests are implemented in the fs package because it's
      easier there. They also test MaxReadAhead.
      
      Tested on Linux 4.19.0 and Linux 6.1.7 via all.bash,
      and on 6.1.7 also via the gocryptfs test suite.

      Make ReadDirPlus configurable · 915cf541
      Tamas Kerecsen authored
      When ReadDirPlus is enabled, the FUSE fs has to gather a lot of additional data for every file even if it won't be used (for example when the user is doing and 'ls' or a large glob). This can cause performance problems, so it should be possible to switch to the simple ReadDir behavior for file systems where this is a bottleneck.

      Make OSXFUSE handle timeouts the same way as Linux · d01fda7e
      Jille Timmermans authored
      OSXFUSE applies a 60-second timeout for file operations. This
      is inconsistent with how FUSE works on Linux, where operations
      last as long as the daemon is willing to let them run.

      unionfs: remove library · f4cec619
      Han-Wen Nienhuys authored
      This library was created as a mechanism to overlay a writable checkout
      for Git on top of Google's readonly SrcFS filesystem. This use case
      has long disappeared, and the unionfs library appears unused
      otherwise. Due to its reliance on timestamps and delays, it is very
      susceptible to flakiness in tests.
      
      Fixing this seems hard or maybe even impossible, so just remove the
      library.

      fuse: prefer fusermount3 over fusermount; add debug output · 934a183e
      Jakob Unterwurzacher authored
      fusermount is (usually) from libfuse v2, and fusermount3 is from
      libfuse v3, which is the actively-developed version.
      
      Importantly, libfuse v3 added ExFAT to the list of filesystems
      that users are allowed to mount on, and libfuse v2 did not.
      
      The only ABI difference between fusermount and fusermount3 that
      I am aware of is that fusermount3 dropped the allow_empty option.
      
      Filesystems had to deal with that already, as fusermount may
      also be from libfuse v3, depending on what the distro does.
      
      This commit also adds two lines of debug output about which binary
      we actually call.
      
      Passes all.bash & the gocryptfs test suite.
