Michael Eischer bfb56b78e1 replace some usages of restic.Repository with more specific interface 
This should eventually make it easier to test the code.

fuse: Better inode generation

greatroar 189e0fe5a9 fuse: Better inode generation 
Hard links to the same file now get the same inode within the FUSE
mount. Also, inode generation is faster and, more importantly, no longer
allocates.

Benchmarked on Linux/amd64. Old means the benchmark with

        sink = fs.GenerateDynamicInode(1, sub.node.Name)

instead of calling inodeFromNode. Results:

name                   old time/op    new time/op    delta
Inode/no_hard_links-8     137ns ± 4%      34ns ± 1%   -75.20%  (p=0.000 n=10+10)
Inode/hard_link-8        33.6ns ± 1%     9.5ns ± 0%   -71.82%  (p=0.000 n=9+8)

name                   old alloc/op   new alloc/op   delta

Inode/hard_link-8         0.00B          0.00B           ~     (all equal)

Michael Eischer 220eaee76b mount: switch to anacrolix fork of bazil/fuse 
The anacrolix fork contains the latest changes from bazil/fuse and
additionally provides support for recent versions of macFUSE.

Michael Eischer dd7cd5b9b3 fuse: remove unused context parameter 2022-08-26 20:48:48 +02:00
Michael Eischer a0c1ae9f90 mount: Correctly return context.Canceled for interrupted syscalls 
bazil/fuse expects us to return context.Canceled to signal that a
syscall was successfully interrupted. Returning a wrapped version of
that error however causes the fuse library to signal an EIO (input/output
error). Thus unwrap context.Canceled errors before returning them.

Michael Eischer fbcbd5318c repository: extract LoadTree/SaveTree 
The repository has no real idea what a Tree is. So these methods never
belonged there.

Michael Eischer d05c88a5d6 fuse: Properly set uid/gid for directories 
In #2584 this was changed to use the uid/gid of the root node. This
would be okay for the top-level directory of a snapshot, however, this
change also applied to normal directories within a snapshot. This
change reverts the problematic part and adds a test that directory
attributes are represented correctly.

Alexander Weiss f8316948d1 Optimize FUSE - make command `restic mount` faster and consume less memory 
- Add Open() functionality to dir
- only access index for blobs when file is read
- Implement NodeOpener and put one-time file stuff there
- Add comment about locking as suggested by bazil.org/fuse

=> Thanks at Michael Eischer for suggesting the last two improvements

greatroar 649cbec6c5 Simplify build tags for restic mount 
This command can only be built on Darwin, FreeBSD and Linux
(and if we upgrade bazil.org/fuse, only FreeBSD and Linux:
https://github.com/bazil/fuse/issues/224).

Listing the few supported operating systems explicitly here makes
porting restic to new platforms easier.

Jasper Lievisse Adriaanse 96311d1a2b Add support for illumos/Solaris 
This does come without xattr/fuse support at this point.

NB: not hooking up the integration tests as restic won't compile without
    cgo with Go < 1.10.
