In this commit we enabled PartialUploads for the union backend.
3faa84b47c combine,compress,crypt,hasher,union: support wrapping backends with PartialUploads
This turns out to cause test failures in fs/sync so this commit
disables them again pending further investigation.
Set this automatically for any backend which implements UnWrap and
manually for combine and union which can't implement UnWrap but do
overlay other backends.
Before this fix, if uploading to a union consisting of all bucket
based remotes (eg s3), uploads failed with:
Failed to copy: object not found
This was because the union backend was relying on parent directories
being created to work out which files to upload. If all the upstreams
were bucket based backends which can't hold empty directories, no
directories were created and the upload failed.
This fixes the problem by returning the upstreams used when creating
the directory for the upload, rather than searching for them again
after they've been created.
This will also make the union backend a little more efficient.
Fixes#6170
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
Before this change the union's feature flags were a strict AND of the
underlying remotes. This means that a union of a local disk (which can
Move but not Copy) and a bucket based remote (which can Copy but not
Move) could neither Move nor Copy.
This fix advertises Move in the union if all the remotes can Move or
Copy. It also implements Move as Copy+Delete (like rclone does
normally) if the underlying union does not support Move.
This enables renames to work with unions of local disk and bucket
based remotes expected.
Fixes#5632
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
Before this change writing with the all policy deadlocked while
uploading.
This change fixes the problem by fixing the multi reader, closing the
pipes at the correct time with the correct error. This is factored
into a new function as it was used twice.
This patch also adds a new test which tests the all policies.
Before this change we errored out if one upstream errored in Purge or
About.
This change checks for fs.ErrorDirNotFound and skips that backend in
this case.
- add a directory to the optional Purge interface
- fix up all the backends
- add an additional integration test to test for the feature
- use the new feature in operations.Purge
Many of the backends had been prepared in advance for this so the
change was trivial for them.
Enable fast list functions for union backend when:
- at least one of the upstreams supports fast list
- upstreams only consist of backends that support fast list and local backend.
Fixes#3000
- 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.
Before this change the union remote was using whether the writable
union could poll for changes to decide whether the union mount could
poll for changes.
The fix causes the union backend to signal it can poll for changes if
**any** of the remotes can poll for changes.
