Currently, the cmd/restic package contains a significant amount of code
that modifies repository internals. This code should in the mid-term
move into the repository package.
`writeStatus` also cleans no longer used status lines.
The old code actually cleaned one line too much. However, as that line
was never used it makes no difference.
If a lock could not be loaded, then restic would check all lock files
again. These repeated checks are not useful as the status of a lock file
cannot change unless its ID changes too. Thus, skip already check lock
files on retries.
LoadBlobsFromPack is now part of the repository struct. This ensures
that users of that method don't have to deal will internals of the
repository implementation.
The filerestorer tests now also contain far fewer pack file
implementation details.
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.
clarify documentation regarding B2 bucket lifecycle settings. The default lifecycle setting is probably fine for most users now; a custom policy is not necessary.
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.
