To only stream the content of a pack file once, check used StreamPack
with a custom pack load function. This combination was always brittle
and complicates using StreamPack everywhere else. Now that StreamPack
internally uses PackBlobIterator use that primitive instead, which is a
much better fit for what the check command requires.
If client.Do returns an error, then there's no body that has to be
closed. For requests for which we are not interested in the response
body, immediately drain and close the body to make sure it isn't
forgotten later on.
This change in particular adds the missing `Close()` call for the
`List()` command.
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
unlikely to be important
- find: filtered directories would be ignored. However, this
optimization missed that it is possible that two directories have the
exact same content. Such directories would be incorrectly ignored too.
Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```
Thus, remove the functionality as it's apparently too complex to use
correctly.
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.
The behavior of the new option should reflect the behavior of normal backups: when the command exit code is zero and there is no output in the stdout, emit a warning but create the snapshot. This commit fixes the integration tests and the ReadCloserCommand struct.
Return with an error containing the stderr of the given command in case it fails. No new snapshot will be created and future prune operations on the repository will remove the unreferenced data.

In order to determine whether to save a snapshot, we need to capture the exit code returned by a command. In order to provide a nice error message, we supply stderr as well.
