For uploads which are coming from disk or going to disk or going to a
backend which doesn't need to seek except for retries this doesn't
buffer the input.
This dramatically reduces rclone's memory usage.
Fixes#7350
When using `--no-traverse` the march routines call NewObject on each
potential object in the destination.
The concurrency limiter was accidentally arranged so that there were
`--checkers` * `--checkers` NewObject calls going on at once.
This became obvious when using the sftp backend which used too many
connections.
Fixes#5824
After the copy refactor:
179f978f75 operations: refactor Copy into methods on an temporary object
There was some confusion in the code about server side copies - should
they or shouldn't they use partials?
This manifested in unit test failures for remotes which supported
server side Copy and PartialUploads. This combination is rare and only
exists in the sftp backend with the --sftp-copy-is-hardlink flag.
This fix makes the choice that backends which set PartialUploads
always use partials even for server side copies.
operations.Copy had become very unwieldy. This refactors it into
methods on a copy object which is created for the duration of the
copy. This makes it much easier to read and reason about.
This almost 100% backwards compatible. The only difference being that
in the rc options/get output DumpMode will be output as strings
instead of integers. This is a lot more convenient for the user. They
still accept integer inputs though so the fallout from this should be
minimal.

Before this change backend types were printing incorrectly as the name
of the type, not what was defined by the Type() method.
This was not working due to not calling the Type() method. However
this needed to be defined on a non-pointer type due to the way the
options are handled.
Before this change, the maximum number of connections was set to 10.
This means that b2 could deadlock while uploading multipart uploads
due to a lock being held longer than it should have been.
Before this change the concurrency used for an upload was rather
inconsistent.
- if size below `--backend-upload-cutoff` (default 200M) do single part upload.
- if size below `--multi-thread-cutoff` (default 256M) or using streaming
uploads (eg `rclone rcat) do multipart upload using
`--backend-upload-concurrency` to set the concurrency used by the uploader.
- otherwise do multipart upload using `--multi-thread-streams` to set the
concurrency.
This change makes the default for the concurrency used be the
`--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger
than the `--backend-upload-concurrency` then that will be used instead.
This means that if the user sets `--backend-upload-concurrency` then it will be
obeyed for all multipart/multi-thread transfers and the user can override them
all with `--multi-thread-streams`.
See: #7056
- fix docs and error messages for multithread
- use sync/errgroup built in concurrency limiting
- re-arrange multithread code
- don't continue multi-thread uploads if one part fails
Before this change, when using --cutoff-mode=soft and --max-duration
rclone deadlocked when the cutoff limit was reached.
This was because the sync objects Pipe became full and nothing was
emptying it because the cutoff was reached.
This changes the context for putting items into the pipe to be the one
that gets cancelled when the cutoff is reached.

Currently, the average transfer speed will stop calculating 1 minute
after the last queued transfer completes. This causes the average to
stop calculating when checking is slow and the transfer queue becomes
empty.
This change will require all checks to complete before stopping the
average speed calculation.
In this commit:
432d5d1e20 operations: fix overlapping check on case insensitive file systems
We introduced a test that makes no sense. This happens to pass without --fast-list and fail with it.
This removes the test.
