Some tests have to explicitly create pack files with blobs that don't
match their ID. For those blobs the builtin verification of the
repository must be disabled.
rclone returns a "not found" error if an internal error occurs while
listing a folder. Ignoring this error lets restic erroneously think that
there are no files, which can cause `prune` to wipe the whole
repository.
Writing these blobs to their files can take a long time and consequently
cause the backend connection to time out. Avoid that by retrieving these
blobs separately.
If an error occurred while streaming a pack file, this could result in
passing some of the blobs multiple times to the callback function. This
significantly complicates using StreamPack correctly and is unnecessary.
Retries do not change the content of a blob and thus only deliver the
same result over and over again.
Since Go 1.21, most reparse points are considered as irregular files.
Depending on the underlying driver these can exhibit nearly arbitrary
behavior. When encountering such a file, restic returned an
indecipherable error message: `error: invalid node type ""`.
Add the filepath to the error message and state that the file type is
not supported.
For now, the guide is only shown if the blob content does not match its
hash. The main intended usage is to handle data corruption errors when
using maximum compression in restic 0.16.0
Allow setting custom arguments for the `sftp` backend, by using the
`sftp.args` option. This is similar to the approach already implemented
in the `rclone` backend, to support new arguments without requiring
future code changes for each different SSH argument.
Closes #4241
Store oversized blobs in separate pack files as the blobs is large
enough to warrant its own pack file. This simplifies the garbage
collection of such blobs and keeps the cache smaller, as oversize (tree)
blobs only have to be downloaded if they are actually used.
The old version was taken from an MPL-licensed library. This is a
cleanroom implementation. The code is shorter and it's now explicit that
only Linux ACLs are supported.
The test uses `WithTimeout` to create a context that cancels the List
operation after a given delay. Several backends internally use a derived
child context created using WithCancel.
The cancellation of a context first closes the done channel of the
context (here: the `WithTimeout` context) and _afterwards_ propagates
the cancellation to child contexts (here: the `WithCancel` context).
Therefor if the List implementation uses a child context, then it may
take a moment until that context is also cancelled. Thus give the
context cancellation a moment to propagate.
