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.
A stale lock may be refreshed if it continues to exist until after a
replacement lock has been created. This ensures that a repository was
not unlocked in the meantime.
When transferring a repository from S3 to, for example, a local disk
then all empty folders will be missing.
When saving files, the missing intermediate folders are created
automatically. Therefore, missing directories can be ignored by the
`List()` operation.
