Michael Eischer aa4647f773 repository: unexport PackBlobIterator 2024-05-18 21:42:51 +02:00
Michael Eischer 94e863885c check: move verification of individual pack file to repository 2024-05-18 21:42:50 +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.

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 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.
 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.

Rework repository.StreamPacks & better restorer error handling
 2024-05-01 16:37:41 +02:00
Michael Eischer 940a3159b5 let index.Each() and pack.Size() return error on canceled context 
This forces a caller to actually check that the function did complete.

Michael Eischer 20d8eed400 repository: streamPack: separate requests for gap larger than 1MB 
With most cloud providers, traffic is much more expensive than API
calls. Thus slightly bias streamPack towards a bit more API calls in
exchange for slightly less traffic.

Michael Eischer 666a0b0bdb repository: streamPack: replace streaming with chunked download 
Due to the interface of streamPack, we cannot guarantee that operations
progress fast enough that the underlying connections remains open. This
introduces partial failures which massively complicate the error
handling.

Switch to a simpler approach that retrieves the pack in chunks of 32MB.
If a blob is larger than this limit, then it is downloaded separately.

To avoid multiple copies in memory, an auxiliary interface
`discardReader` is introduced that allows directly accessing the
downloaded byte slices, while still supporting the streaming used by the
`check` command.

Michael Eischer 621012dac0 repository: Add blob loading fallback to LoadBlobsFromPack 
Try to retrieve individual blobs via LoadBlob if streaming did not work.

Michael Eischer defd7ae729 prune/repair index: reset in-memory index after command 
The current in-memory index becomes stale after prune or repair index
have run. Thus, just drop the in-memory index altogether once these
commands have finished.

Michael Eischer 310db03c0e repair index: improve log output if index cannot be deleted 
The operation will always fail with an error if an index cannot be
deleted. Thus, this change is purely cosmetic.
