greatroar f90bf84ba7 test: Use testing.T.Cleanup to remove tempdirs 2022-12-09 14:23:55 +01:00
Michael Eischer ff7ef5007e Replace most usages of ioutil with the underlying function
The ioutil functions are deprecated since Go 1.17 and only wrap another
library function. Thus directly call the underlying function.

This commit only mechanically replaces the function calls.

Michael Eischer 5b6a77058a Enable sparseness only conditionally
We can either preallocate storage for a file or sparsify it. This
detects a pack file as sparse if it contains an all zero block or
consists of only one block. As the file sparsification is just an
approximation, hide it behind a `--sparse` parameter.

Michael Eischer 6f53ecc1ae adapt workers based on whether an operation is CPU or IO-bound
Use runtime.GOMAXPROCS(0) as worker count for CPU-bound tasks,
repo.Connections() for IO-bound task and a combination if a task can be
both. Streaming packs is treated as IO-bound as adding more worker
cannot provide a speedup.

Typical IO-bound tasks are download / uploading / deleting files.
Decoding / Encoding / Verifying are usually CPU-bound. Several tasks are
a combination of both, e.g. for combined download and decode functions.
In the latter case add both limits together. As the backends have their
own concurrency limits restic still won't download more than
repo.Connections() files in parallel, but the additional workers can
decode already downloaded data in parallel.

Igor Fedorenko f17ffa0283 restorer: Allow writing target file blobs out of order
Much simpler implementation that guarantees each required pack
is downloaded only once (and hence does not need to manage
pack cache). Also improves large file restore performance.

Igor Fedorenko bda8d7722e restorer: Optimize empty file restore
don't create fileInfo structs for empty files. this saves memory.
this also avoids extra serial scan of all fileInfo, which should
make restore faster and more consistent.

Igor Fedorenko 9f3ca97ee8 restore: Chang fileInfo to use snapshot location instead of target path
* uses less memory as common prefix is only stored once
* stepping stone for simpler error callback api, which
  will allow further memory footprint reduction
