The new functions much better convey the intent behind the lock
request. This allows cleanly integrating noLock (for read) and dryRun
(write/exclusive) handling.
There are only minor changes to existing behavior with two exceptions:
- `tag` no longer accepts the `--no-lock` flag. As it replaces files in
the repository, this always requires an exclusive lock.
- `debug examine` now returns an error if both `--extract-pack` and
`--no-lock` are given.
This change better resembles the output generated by `Snapshot.String()`,
which includes both username and hostname.
Closes#4506

Adds
* snapshotMetadataArgs, which holds the new metadata as strings parsed from
the command line
* snapshotMetadata, which holds the new metadata converted to the
correct types
The previous approach of rewriting all snapshots first, then flushing
the repository data and finally removing old snapshots has the downside
that an interrupted command execution leaves behind broken snapshots as
not all new data is already flushed.
This adds support for caching already rewritten trees, handling of load
errors and disabling the check that the serialization doesn't lead to
data loss.
The more generic RewriteNode callback replaces the SelectByName and
PrintExclude functions. The main part of this change is a preparation to
allow using the TreeRewriter for the `repair snapshots` command.
Fixes restic#719
If the option is passed, restic will wait the specified duration of time
and retry locking the repo every 10 seconds (or more often if the total
timeout is relatively small).
- Play nice with json output
- Reduce wait time in lock tests
- Rework timeout last attempt
- Reduce test wait time to 0.1s
- Use exponential back off for the retry lock
- Don't pass gopts to lockRepo functions
- Use global variable for retry sleep setup
- Exit retry lock on cancel
- Better wording for flag help
- Reorder debug statement
- Refactor tests
- Lower max sleep time to 1m
- Test that we cancel/timeout in time
- Use non blocking sleep function
- Refactor into minDuration func

This turns snapshotFilterOptions from cmd into a restic.SnapshotFilter
type and makes restic.FindFilteredSnapshot and FindFilteredSnapshots
methods on that type. This fixes#4211 by ensuring that hosts and paths
are named struct fields instead of unnamed function arguments in long
lists of such.
Timestamp limits are also included in the new type. To avoid too much
pointer handling, the convention is that time zero means no limit.
That's January 1st, year 1, 00:00 UTC, which is so unlikely a date that
we can sacrifice it for simpler code.
The Original field is meant to remember the original snapshot id if e.g.
changing its tags. It was only set by the `rewrite` command if it was
not set previously. However, a rewritten snapshot is potentially rather
different from the original snapshot. Thus just always set the Original
field. This also makes it easier to later on detect and potentially
remove the original snapshots.
The old check did not consider files containing case insensitive
excludes. The check is now implemented as a function of the
excludePatternOptions struct to improve cohesion.
