Nick Craig-Wood 70c8566cb8 fs: Pin created backends until parents are finalized 
This attempts to solve the backend lifecycle problem by

- Pinning backends mentioned on the command line into the cache
  indefinitely

- Unpinning backends when the containing structure (VFS, wrapping
  backend) is destroyed

See: https://forum.rclone.org/t/rclone-rc-backend-command-not-working-as-expected/18834

Nick Craig-Wood 47d08ac1f1 vfs: recommend --vfs-cache-modes writes on backends which can't stream 2020-08-18 17:33:27 +01:00
Nick Craig-Wood 15402e46c9 vfs: Add recovered items on cache reload to directory listings 
Before this change, if we restarted an upload after a restart then the
file would get uploaded but never added to the directory listings.

This change makes sure we add virtual items to the directory cache
when reloading the cache so that they show up properly.

Nick Craig-Wood 7781ea8d59 vfs: add an optional fs parameter to vfs rc methods 
Before this change we initialized the rc for a single VFS. However
rclone can have multiple VFSes in use now so this is no longer
adequate.

This change adds an optional fs parameter to all the VFS methods to
disambiguate VFSes when there is more than one in use.

It also adds a method vfs/list to show all the active VFSes.

This adds outline tests for the rc commands which didn't have tests
before.

This means we can reliably look up the Fs from the cache when using
`backend/command`.

In

54deb01f00 vfs: Make OpenFile and friends return EINVAL if O_RDONLY and O_TRUNC

The generated file open_test.go was edited directly without editing
the generator.

This commit brings the generator make_open_tests.go back into line
with that edit. It also makes it so `go generate` can be used to
regenerate the tests.

Nick Craig-Wood 393b94bb70 vfs: add --vfs-read-wait and --vfs-write-wait flags 
--vfs-read-wait duration    Time to wait for in-sequence read before seeking. (default 5ms)
    --vfs-write-wait duration   Time to wait for in-sequence write before giving error. (default 1s)

Nick Craig-Wood 76f5e273d2 vfs: stop change notify polling clearing so much of the directory cache 
Before this change, change notify polls would clear the directory
cache recursively. So uploading a file to the root would clear the
entire directory cache.

After this change we just invalidate the directory cache of the parent
directory of the item and if the item was a directory we invalidate it
too.

Brett Dutro 7d0d7e66ca vfs: move writeback of dirty data out of close() method into its own method (FlushWrites) and remove close() call from Flush() 
If a file handle is duplicated with dup() and the duplicate handle is
flushed, rclone will go ahead and close the file, making the original
file handle stale. This change removes the close() call from Flush() and
replaces it with FlushWrites() so that the file only gets closed when
Release() is called. The new FlushWrites method takes care of actually
writing the file back to the underlying storage.

Fixes #3381

Aleksandar Jankovic f78cd1e043 Add context propagation to rclone 
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions

Context propagation is needed for stopping transfers and passing other
request-scoped values.

Fabian Möller 1d14972e41 vfs: reduce directory cache cleared by poll-interval 
Reduce the number of nodes purged from the dir-cache when ForgetPath is
called. This is done by only forgetting the cache of the received path
and invalidating the parent folder cache by resetting *Dir.read.

The parent will read the listing on the next access and reuse the
dir-cache of entries in *Dir.items.

Nick Craig-Wood 2b7957cc74 vfs: Only make the VFS cache if --vfs-cache-mode > Off 
This stops the cache cleaner running unnecessarily and saves
resources.

This also helps with issue #2227 which was caused by a second mount
deleting objects in the first mounts cache.

Nick Craig-Wood 54deb01f00 vfs: Make OpenFile and friends return EINVAL if O_RDONLY and O_TRUNC 
Before this change Open("name", os.O_RDONLY|os.O_TRUNC) would have
truncated the file.  This is what Linux does, but is counterintuitive.
POSIX states this is undefined, so return an error in this case
instead.  This preserves the invariant O_RDONLY => file is not
changed.

Nick Craig-Wood a80d8a21dc vfs: add flags parameter to Dir.Create 2018-01-19 13:18:40 +00:00
Nick Craig-Wood 11da2a6c9b Break the fs package up into smaller parts. 
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.

The new code layout is documented in CONTRIBUTING.
