Michael Eischer 7266f07c87 repository: StreamPack in parts if there are too large gaps 
For large pack sizes we might be only interested in the first and last
blob of a pack file. Thus stream a pack file in multiple parts if the
gaps between requested blobs grow too large.

greatroar ad6ac680af internal/restic: Handle EINVAL for xattr on Solaris 
Also make the errors a bit less verbose by not prepending the operation,
since pkg/xattr already does that. Old errors looked like

    Listxattr: xattr.list /myfiles/.zfs/snapshot: invalid argument

Michael Eischer 623770eebb repository: try to recover from invalid blob while repacking 
If a blob that should be kept is invalid, Repack will now try to request
the blob using LoadBlob. Only return an error if that fails.

Michael Eischer d0590b7841 prune: Add internal integrity check 
After repacking every blob that should be kept must have been repacked.
We have seen a few cases in which a single blob went missing, which
could have been caused by a bitflip somewhere. This sanity check might
help catch some of these cases.

greatroar 2bdc40e612 Speed up restic init over slow SFTP links 
pkg/sftp.Client.MkdirAll(d) does a Stat to determine if d exists and is
a directory, then a recursive call to create the parent, so the calls
for data/?? each take three round trips. Doing a Mkdir first should
eliminate two round trips for 255/256 data directories as well as all
but one of the top-level directories.

Also, we can do all of the calls concurrently. This may reintroduce some
of the Stat calls when multiple goroutines try to create the same
parent, but at the default number of connections, that should not be
much of a problem.

Michael Eischer 2ba14160de Add changelog for the optimized tree serialization 2022-07-23 14:49:08 +02:00
Michael Eischer 4a10ebed15 archiver: reduce memory usage for large files 
FutureBlob now uses a Take() method as a more memory-efficient way to
retrieve the futures result. In addition, futures are now collected
while saving the file. As only a limited number of blobs can be queued
for uploading, for a large file nearly all FutureBlobs already have
their result ready, such that the FutureBlob object just consumes
memory.

Michael Eischer b817681a11 archiver: Incrementally serialize tree nodes 
That way it is not necessary to keep both the Nodes forming a Tree and
the serialized JSON version in memory.

Michael Eischer c206a101a3 archiver: unify FutureTree/File into futureNode 
There is no real difference between the FutureTree and FutureFile
structs. However, differentiating both increases the size of the
FutureNode struct.

The FutureNode struct is now only 16 bytes large on 64bit platforms.
That way is has a very low overhead if the corresponding file/directory
was not processed yet.

There is a special case for nodes that were reused from the parent
snapshot, as a go channel seems to have 96 bytes overhead which would
result in a memory usage regression.
