Michael Eischer 673496b091 repository: clean cache between CheckPack retries
The cache cleanup pattern is also used in ListPack etc.

Michael Eischer 3d2410ed50 Replace some repo.RemoveUnpacked usages
These will eventually be blocked as they do not delete Snapshots.

Michael Eischer e40943a75d restic: remove backend usage from lock test 2024-05-18 21:38:31 +02:00
Michael Eischer 67e2ba0d40 repository: Lock requires *repository.Repository
This allows the Lock function to access the backend, even once the
Backend method is removed from the interface.

Michael Eischer d8b184b3d3 repository: convert test helper to return *repository.Repository 2024-05-18 21:38:31 +02:00
Michael Eischer a1ca5e15c4 migrations: add temporary hack for s3_layout
The migration will be removed after the next restic release anyways.
Thus, there's no need for a clean implementation.

Michael Eischer 34d90aecf9 migrations: move logic of upgrade_repo_v2 to repository package
The migration modifies repository internals and thus should live within
the repository package.
2024-05-18 21:38:31 +02:00
Michael Eischer ab9077bc13 replace usages of backend.Remove() with repository.RemoveUnpacked()
RemoveUnpacked will eventually block removal of all filetypes other than
snapshots. However, getting there requires a major refactor to provide
some components with privileged access.

Michael Eischer 74d90653e0 check: use ReadFull to load pack header in checkPack
This ensures that the pack header is actually read completely.
Previously, for a truncated file it was possible to only read a part of
the header, as backend.Load(...) is not guaranteed to return as many
bytes as requested by the length parameter.

Michael Eischer e734746f75 cache: forget cached file at most once
This is inspired by the circuit breaker pattern used for distributed
systems. If too many requests fails, then it is better to immediately
fail new requests for a limited time to give the backend time to
recover.

By only forgetting a file in the cache at most once, we can ensure that
a broken file is only retrieved once again from the backend. If the file
stored there is broken, previously it would be cached and deleted
continuously. Now, it is retrieved only once again, all later requests
just use the cached copy and either succeed or fail immediately.

Michael Eischer 97a307df1a cache: Always use cached file if it exists
A file is always cached whole. Thus, any out of bounds access will also
fail when directed at the backend. To handle case in which the cached
file is broken, then caller must call Cache.Forget(h) for the file in
question.

Michael Eischer 433a6aad29 repository: remove redundant blob loading fallback from RepairPacks
LoadBlobsFromPack already implements the same fallback behavior.

Michael Eischer 021fb49559 repository: Implement repository.LoadUnpacked using LoadRaw
Both functions were using a similar implementation.

Michael Eischer 779c8d3527 debug/repair packs/upgrade repo v2: use repository.LoadRaw
This replaces calling the low-level backend.Load() method.
2024-05-18 21:26:00 +02:00
Michael Eischer 1d6d3656b0 repository: move backend.LoadAll to repository.LoadRaw
LoadRaw also includes improved context cancellation handling similar to the
implementation in repository.LoadUnpacked.

The removed cache backend test will be added again later on.

Michael Eischer 53d15bcd1b retry: add circuit breaker to load method
If a file exhausts its retry attempts, then it is likely not accessible
the next time. Thus, immediately fail all load calls for that file to
avoid useless retries.

Michael Eischer 394c8ca3ed rest/rclone/s3/sftp/swift: move short file detection behind feature gate
These backends tend to use a large variety of server implementations.
Some of those implementations might prove problematic with the new
checks.

Michael Eischer aeb7eb245c retry: do not retry permanent errors
This is currently gated behind a feature flag as some unexpected
interactions might show up in the wild.

Michael Eischer bf8cc59889 Use generic backend-error-redesign feature flag instead of http-timeouts
An individual flag for each change of the backend error handling would
be too finegrained. Thus, add a generic flag.
