Michael Eischer b7ff8ea9cd repository: expose cache via method 2025-01-13 22:40:18 +01:00
Michael Eischer 99e105eeb6 repository: restrict SaveUnpacked and RemoveUnpacked
Those methods now only allow modifying snapshots. Internal data types
used by the repository are now read-only. The repository-internal code
can bypass the restrictions by wrapping the repository in an
`internalRepository` type.

The restriction itself is implemented by using a new datatype
WriteableFileType in the SaveUnpacked and RemoveUnpacked methods. This
statically ensures that code cannot bypass the access restrictions.

The test changes are somewhat noisy as some of them modify repository
internals and therefore require some way to bypass the access
restrictions. This works by capturing an `internalRepository` or
`Backend` when creating the Repository using a test helper function.

repository: removed redundant prepareCache method from Repository
* remove the prepareCache method from the Repository
* changed the signature of the SetIndex function to no longer return an error

Michael Eischer bab760369f repository: double check that there is not repository before init
Apparently, calling `Stat` on the config file can be unreliable for some
backends.

Michael Eischer 462b82a060 index: reduce size of compressed indexes
use the same index size for compressed and uncompressed indexes.
Otherwise, decoding the index of a compressed repository requires
significantly more memory.

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 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 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 2dbb18128c repository: Allow skipping verification for tests
Some tests have to explicitly create pack files with blobs that don't
match their ID. For those blobs the builtin verification of the
repository must be disabled.

This only covers the blobs themselves, the pack header is not verified
so far. Unpacked files are also not covered by the integrity check.
