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`.

This makes the memory controls of the s3 backend inoperative and
replaced with the global ones.
--s3-memory-pool-flush-time
--s3-memory-pool-use-mmap
By using the buffered reader this fixes excessive memory use when
uploading large files as it will share memory pages between all
readers.
Fixes#7141
This introduces a new fs.Option flag, Sensitive and uses this along
with IsPassword to redact the info in the config file for support
purposes.
It adds this flag into backends where appropriate. It was necessary to
add oauthutil.SharedOptions to some backends as they were missing
them.
Fixes#5209
Before this change we were incorrectly identifying the root directory
of the listing and adding it into the listing.
This caused higher layers of rclone to emit the error above.
See #7038
Before this change if the storage class wasn't set on the object, we
didn't set the "tier" metadata.
This made it impossible to filter on tier using the metadata filters.
This returns the "tier" metadata as STANDARD if the storage class
isn't set on the object.

- Report correct feature flag

- don't output the root directory marker
- Don't create the directory marker if it is the bucket or root

Apparently the abort multipart upload call doesn't return while
multipart uploads are in progress on iDrive e2.
This means that if we CTRL-C a multpart upload rclone hangs until the
all parts uploading have completed. However since rclone is uploading
multiple parts at once this doesn't happen until after the entire file
is uploaded.
This was fixed by cancelling the upload context which causes all the
uploads to stop instantly.
Before this change, we would upload files as single part uploads even
if the source MD5SUM was not available.
AWS won't let you upload a file to a locket bucket without some sort
of hash protection of the upload which we don't have with no MD5SUM.
So we switch to multipart upload when the source does not have an
MD5SUM.
This means that if --s3-disable-checksum is set or we are copying from
a source with no MD5SUMs we will copy with multipart uploads.
This patch changes all uploads, not just those to locked buckets
because having no MD5SUM protection on uploads is undesirable.
Fixes#6846
Before this change if an --s3-profile was set which used AWS STS (eg
to assume a role) and --s3-endpoint was set then rclone would use the
value from --s3-endpoint to contact the STS server which did not work.
This fix implements an endpoint resolver which only overrides the "s3"
service if --s3-endpoint is set. It sends the "sts" service (and any
other service) to the default resolver.
Fixes#6443

Before this change, all types of checkers showed "checking" after the
file name despite the fact that not all of them were checking.
After this change, they can show
- checking
- deleting
- hashing
- importing
- listing
- merging
- moving
- renaming
See: https://forum.rclone.org/t/what-is-rclone-checking-during-a-purge/35931/
Before this change if --s3-no-head was in use rclone didn't check the
multipart upload ETag at all. However the ETag is returned in the
final POST request when completing the object.
This change uses that ETag from the final POST if --s3-no-head is in
use, otherwise it uses the ETag from a fresh HEAD request.

Storj switched to a single global s3 endpoint backed by a BGP routing.
We want to stop advertizing the former regional endpoints and have the
global one as the only option.
Before this change, when a new object was created s3 returns its
versionID (on a versioned bucket) and rclone recorded it in the
object.
This means that when rclone came to delete the object it would delete
it with the versionID.
However it is common to forbid actions with versionIDs on buckets so
as to preserve the historical record and these operations would fail
whereas they succeeded in pre-v1.60.0 versions.
This patch fixes the problem by not recording versions of objects
supplied by the S3 API on upload unless `--s3-versions` or
`--s3-version-at` is used. This makes rclone behave as it did before
v1.60.0 when version support was introduced.

Before this change, we were taking the version ID straight from the
XML blob returned by the SDK and thus pinning the XML into memory
which bulked up the average memory per object from about 400 bytes to
4k.
Copying the string fixes the excess memory usage.
This reverts commit 4f386a1ccd.
It turns out that Alibaba OSS does support list v2 and the detection
code was wrong.
This means that users of the gov version of Alibaba will have to add
`list_version 1` to their config files.
See #6600
In this commit
ab849b3613 s3: fix listing loop when using v2 listing on v1 server
The ContinuationToken was tested for existence, but it is the
NextContinuationToken that we are interested in.
See: #6600
This was caused by
a9bd0c8de6 s3: reduce memory consumption for s3 objects
Which assumed that the StorageClass would always be set, but it isn't
set for Versions.
Before this change, rclone would enter a listing loop if it used v2
listing on a v1 server and the list exceeded 1000 items.
This change detects the problem and gives the user a helpful message.
Fixes#6600
Copying the storageClass string instead of using a pointer to the original string.
This prevents the Go garbage collector from keeping large amounts of
XMLNode structs and references in memory, created by xmlutil.XMLToStruct()
from the aws-sdk-go.
