      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.

      The readPool size was calculated from MaxWrite not taking
      into account that the kernel fails all reads below 8 kiB.
      
      Fix that by always using at least 8kiB.

      A later commit will allow setting MaxPages, so show it in the debug output.
      
      Also print MaxReadahead, MaxWrite, TimeGran in decimal instead of hex -
      these are neither bitfields nor addresses, so it seems clearer to have them in decimal.

      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.
      
      Fixes https://github.com/hanwen/go-fuse/issues/394
      Fixes https://github.com/rfjakob/gocryptfs/issues/626

      fuse: support special /dev/fd/N mountpoint · 74a933d6
      Jakob Unterwurzacher authored
      libfuse introduced [1] a special `/dev/fd/N` syntax for the mountpoint:
      It means that a privileged parent process:
      
       * Opened /dev/fuse
       * Called mount() on a real mountpoint directory
       * Inherited the fd to /dev/fuse to us
       * Informs us about the fd number via /dev/fd/N
      
      This functionality is used to allow FUSE mounts inside containers
      that have neither root permissions nor suid binaries [2], and
      for the --drop_privileges flag of mount.fuse3 [4]
      
      Tested with singularity and gocryptfs and actually works [3].
      
      v2: Added doccomment for NewServer.
      v3: Added specific error message on Server.Unmount().
      v4: Moved mount details to package comment

      	GOMAXPROCS=1 go test -v -count=1 -run TestDeleteNotify ./fuse/test
      
      deadlocked reliably, apparently in the chdir() from cmd.Start().
      
      We can do without the chdir() by using an absolte path.
      This avoids the issue.
      
      Fixes https://github.com/hanwen/go-fuse/issues/261

      fuse: suppress ENOENT warnings for INTERRUPT responses · eefea5e0
      Tommy Lindgren authored
      If writing the INTERRUPT response returns ENOENT it means that the
      referred request is no longer known by the kernel. This is a normal if
      the referred request already has completed. We thus suppress the scary
      warning unless debugging is enabled.
      
      Fixes #375.
