Michael Eischer e638b46a13 Embed context into ReaderAt
The io.Reader interface does not support contexts, such that it is
necessary to embed the context into the backendReaderAt struct. This has
the problem that a reader might suddenly stop working when it's
contained context is canceled. However, this is now problem here as the
reader instances never escape the calling function.

Michael Eischer 4b0fcaed45 unlock: use proper context for locks cleanup
The list operation used by RemoveStaleLocks or RemoveAllLocks will
already be canceled by the passed in context. Therefore we can also just
cancel the remove operation as the unlock command won't process all lock
files anyways.
2020-10-09 22:37:56 +02:00
Michael Eischer c458e114d4 pass context to Find / FindSnapshot
This allows proper interruption of restic while it searches for
snapshots or key files.

Michael Eischer 184103647a FindUsedBlobs: merge seen into blobs BlobSet
The seen BlobSet always contained a subset of the entries in blobs.
Thus use blobs instead and avoid the memory overhead of the second set.

greatroar 7bda28f31f Chaining hash table for repository.Index
These are faster to construct but slower to access. The allocation rate
is halved, the peak memory usage almost halved compared to standard map.

Alexander Weiss 91906911b0 Fix non-intuitive repository behavior
- The SaveBlob method now checks for duplicates.
- Moves handling of pending blobs to MasterIndex.
  -> also cleans up pending index entries when they are saved in the index
  -> when using SaveBlob no need to care about index any longer
- Always check for full index and save it when storing packs.
  -> removes the need of an index uploader
  -> also removes the verbose "uploaded intermediate index" messages
- The Flush method now also saves the index
- Fix race condition when checking and saving full/non-finalized indexes
