Michael Eischer 95bcc9ea31 debug: Support pack ID prefixes in `debug examine` 2022-04-30 20:20:31 +02:00
Michael Eischer 2d6a943911 debug: Add switch to upload blobs extracted by debug examine 
This simplifies salvaging a damaged pack file. Reuploading tree blobs
was previously not possible.

Michael Eischer dbbeac7174 prune: Add unsafe option to recover from no free space 
The new option allows prune to operate with nearly no scratch space by only removing
no longer necessary pack files and first deleting the index before
rebuilding it. By first deleting the index it becomes safe to just
delete no longer necessary pack files. However, as a downside there's
now the risk that the repository becomes inaccessible if prune fails.

To recover from that problem a user might have to manually delete the
repository index and then run (a full) `rebuild-index` again.

Michael Eischer 7132df529e repository: Increase index size for repo version 2 
A compressed index is only about one third the size of an uncompressed
one. Thus increase the number of entries in an index to avoid cluttering
the repository with small indexes.

Michael Eischer 4b957e7373 repository: Implement index/snapshot/lock compression 
The config file is not compressed as it should remain readable by older
restic versions such that these can return a proper error.

As the old format for unpacked data does not include a version header,
make use of a trick: The old data is always encoded as JSON. Thus it can
only start with '{' or '['. For any other value the first byte indicates
a versioned format. The version is set to 2 for now. Then the zstd
compressed data follows.

Michael Eischer f5609d1d3c prune: Fail early if too few backend connections 2022-04-23 11:32:52 +02:00
Michael Eischer e597b99b55 repository: Reduce repack workers to prevent deadlock 
As repack streams packs these occupy one backend connection. Uploading a
new pack also requires a backend connection. To prevent a deadlock
during repack when reaching the backend connections limit, simply limit
the repackWorker count to always leave one connection for uploading.
