Before this change, some files were giving this error when downloaded
from Cloudflare and other providers.
ERROR corrupted on transfer: sizes differ NNN vs MMM
This is because these providers auto gzips the object when rclone
wasn't expecting it to. (AWS does not gzip objects without their being
uploaded gzipped).
This patch adds a quirk to for fix the problem and a flag to control
it. The quirk `might_gzip` is set to `true` for all providers except
AWS.
See: https://forum.rclone.org/t/s3-error-corrupted-on-transfer-sizes-differ-nnn-vs-mmm/33694/Fixes: #6533
Before this fix it was impossible to stop rclone generating an
X-Amx-Acl: header which is incompatible with GCS with uniform access
control and is generally deprecated at AWS.
The API endpoint GetBucketLocation requires
top level permission.
If we do an authenticated head request to a bucket, the bucket location will be returned in the HTTP headers.
Fixes#5066
Before this change if --user-server-modtime was in use the ModTime
could change for an object as we receive it accurate to the nearest ms
in listings, but only accurate to the nearest second in HEAD and GET
requests.
Normally AWS returns the milliseconds as .000 in listings, but if
versions are in use it may not. Storj S3 also seems to return
milliseconds.
This patch tries to keep the maximum precision in the last modified
time, so it doesn't update a last modified time with a truncated
version if the times were the same to the nearest second.

Before this fix, the chunksize calculator was using the previous size
of the object, not the new size of the object to calculate the chunk
sizes.
This meant that uploading a replacement object which needed a new
chunk size would fail, using too many parts.
This fix fixes the calculator to take the size explicitly.
Before this change, if an object compressed with "Content-Encoding:
gzip" was downloaded, a length and hash mismatch would occur since the
go runtime automatically decompressed the object on download.
If --s3-decompress is set, this change erases the length and hash on
compressed objects so they can be downloaded successfully, at the cost
of not being able to check the length or the hash of the downloaded
object.
If --s3-decompress is not set the compressed files will be downloaded
as-is providing compressed objects with intact size and hash
information.

22abd785eb s3: implement reading and writing of metadata #111
The reading information of objects was refactored to use the
s3.HeadObjectOutput structure.
Unfortunately the code branch with `--s3-no-head` was not tested
otherwise this panic would have been discovered.
This shows that this is path is not integration tested, so this adds a
new integration test.
Fixes#6322
The SDK doesn't wrap errors in a Go standard way so they can't be
unwrapped and tested for - eg fatal error.
The code looks for a Serialization or RequestError and returns the
unwrapped underlying error if possible.
This fixes the fs/operations integration tests checking for fatal
errors being returned.

e5974ac4b0 s3: use PutObject from the aws SDK to upload single part objects
rclone was made to upload objects to s3 using PUT requests rather than
using signed uploads.
However this change missed the fact that there is a supported way to
do this in the SDK using the SetStreamingBody method on the Request.
This therefore reverts a lot of the previous commit to do with making
an unsigned connection and other complication and uses the SDK
facility.
strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

Before this change rclone used presigned requests to upload single
part objects. This was because of a limitation in the SDK which didn't
allow non seekable io.Readers to be passed in.
This is incompatible with some S3 backends, and rclone wasn't adding
the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` header which was
incompatible with other S3 backends.
The SDK now allows for this so rclone can use PutObject directly.
This sets the `X-Amz-Content-Sha256: UNSIGNED-PAYLOAD` flag on the PUT
request. However rclone will add a `Content-Md5` header if at all
possible so the body data is still protected.
Note that the old behaviour can still be configured if required with
the `use_presigned_request` config parameter.
Fixes#5422
Before this change the new multipart upload ETag checking code was
failing in the integration tests with Alibaba OSS.
Apparently Alibaba calculate the ETag in a different way to AWS.
This introduces a new provider quirk with a flag to disable the
checking of the ETag for multipart uploads.
Mulpart Etag checking has been enabled for all providers that we can
test for and work, and left disabled for the others.
Before this rclone ignored the ETag on multipart uploads which missed
an opportunity for a whole file integrity check.
This adds that check which means that we now check even harder that
multipart uploads have arrived properly.
See #5993
Before this change a multipart upload with the --no-head flag returned
the MD5SUM as a base64 string rather than a Hex string as the rest of
rclone was expecting.

This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
This removes the checks against the provider throughout the code and
puts them into a single setQuirks function for easy maintenance when
adding a new provider.
It also updates the quirks with the results of testing against
backends we have access to.
This also adds a list_url_encode parameter so that quirk can be
manually set.
This implements a quirks system for providers and notes which
providers we have tested to support ListObjectsV2.
For those providers which don't support ListObjectsV2 we use the
original ListObjects call.
In this commit, released in 1.56.0 we started reading the size of the
object from the Content-Length header as returned by the GET request
to read the object.
4401d180aa s3: add --s3-no-head-object
However some object storage systems, notably Ceph, don't return a
Content-Length header.
The new code correctly calls the setMetaData function with a nil
pointer to the ContentLength.
However due to this commit from 2014, released in v1.18, the
setMetaData function was not ignoring the size as it should have done.

Before this change the `shared_credentials_file` config option was
being ignored.
The correct value is passed into the SDK but it only sets the
credentials in the default provider. Unfortunately we wipe the default
provider in order to install our own chain if env_auth is true.
This patch restores the shared credentials file in the session
options, exactly the same as how we restore the profile.
Original fix:
1605f9e14d s3: Fix shared_credentials_file auth
This patch reverts this commit
1605f9e14d s3: Fix shared_credentials_file auth
It unfortunately had the side effect of making the s3 SDK ignore the
config in our custom chain and use the default provider. This means
that advanced auth was being ignored such as --s3-profile with
role_arn.

This reverts commit
dc06973796 Revert "s3: use rclone's low level retries instead of AWS SDK to fix listing retries"
Which in turn reverted
5470d34740 "backend/s3: use low-level-retries as the number of SDK retries"
So we are back where we started.
It then modifies it to set the AWS SDK to `--low-level-retries`
retries, but set the rclone retries to 2 so that directory listings
can be retried.
The egress charges while using a CloudFront CDN url is cheaper when
compared to accessing the file directly from S3. So added a download
URL advanced option, which when set downloads the file using it.
Before this change, rclone would always check the root to see if it
was an object.
This change doesn't check to see if the root is an object if the path
ends with a /
This avoids a transaction where rclone HEADs the path to see if it
exists.
See #4990
Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.

15d19131bd s3: use aws web identity role provider
This code no longer works because it doesn't initialise the
tokenFetcher - leading to a nil pointer crash.
The proper way to initialise this is with the
NewWebIdentityCredentials but it isn't clear where to get the other
parameters: roleARN, roleSessionName, path.
In the linked issue a user reports rclone working with EKS anyway, so
perhaps this code is no longer needed.
If it is needed, hopefully someone who knows AWS better will come
along and fix it!

fc5b14b620 s3: Added `--s3-disable-http2` to disable http/2
We created our own transport so we could disable http/2. However the
added function is called twice meaning that we create two HTTP
transports. This didn't happen with the original code because the
default transport is cached by fshttp.
Rclone normally does a PUT followed by a HEAD request to check an
upload has been successful.
With the two transports, the PUT and the HEAD were being done on
different HTTP transports. This means that it wasn't re-using the same
HTTP connection, so the HEAD request showed the previous object value.
This caused rclone to declare the upload was corrupted, delete the
object and try again.
This patch makes sure we only create one transport and use it for both
PUT and HEAD requests which fixes the problem with Wasabi.

Before this change, if folder level access permissions policy was in
use, with trailing `/` marking the folders then rclone would HEAD the
path without a trailing `/` to work out if it was a file or a folder.
This returned a permission denied error, which rclone returned to the
user.

53aa03cc44 s3: complete sse-c implementation
rclone would assume any errors when HEAD-ing the object implied it
didn't exist and this test would not fail.
This change reverts the functionality of the test to work as it did
before, meaning any errors on HEAD will make rclone assume the object
does not exist and the path is referring to a directory.
Fixes#4990
S3 backend shared_credentials_file option wasn't working neither from
config option nor from command line option. This was caused cause
shared_credentials_file_provider works as part of chain provider, but in
case user haven't specified access_token and access_key we had removed
(set nil) to credentials field, that may contain actual credentials got
from ChainProvider.
AWS_SHARED_CREDENTIALS_FILE env varible as far as i understood worked,
cause aws_sdk code handles it as one of default auth options, when
there's not configured credentials.
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
Before this change, small objects uploaded with SSE-AWS/SSE-C would
not have MD5 sums.
This change adds metadata for these objects in the same way that the
metadata is stored for multipart uploaded objects.
See: #1824#2827
If rclone is configured for server side encryption - either aws:kms or
sse-c (but not sse-s3) then don't treat the ETags returned on objects
as MD5 hashes.
This fixes being able to upload small files.
Fixes#1824
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
The maximum value for the --s3--copy-cutoff should be 5GiB as tested
with AWS S3.
However b2 have implemented this as 5GB rather than 5GiB so having the
default at 5 GiB makes the b2s3 server side copy of a large file by
default.
This patch sets the default to 4768 MiB which is slightly less than
5GB.
This should have very little effect on anything.
If in future rclone can lower this limit more if Copy can multithread.
See: https://forum.rclone.org/t/copying-files-within-a-b2-bucket/16680/76
Before this change the s3 multipart server side copy was not
preserving the metadata of the object. This was most noticeable
because the modtime was not preserved.
This change fetches the metadata from the object before starting the
copy and overwrites it if requires.
It will also mean any other metadata is preserved.

This reverts part of
151f03378f s3: fix upload of single files into buckets without create permission
This erroneously assumed that a HEAD request on a non existent object
would return "NotFound" if the bucket was found. In fact it returns
"NotFound" when the bucket isn't found also.
This will break the fix for #4297 - however that can be made to work
using the new --s3-assume-bucket-exists flag
This implements `rclone cleanup` to remove multipart uploads over 24
hours old. It also implements the backend command
`list-multipart-uploads` to see which ones are available and `cleanup`
to delete them with a configurable expiry interval.
See #4302
Previous to this fix if Region was not set and Endpoint was not set
then we set the endpoint to "https://s3.amazonaws.com/".
This is unecessary because if the Region alone isn't set then we set
it to "us-east-1" which has the same endpoint.
Having the endpoint set breaks the bucket region auto detection with
the error "Failed to update region for bucket: can't set region to
"xxx" as endpoint is set".
This fix removes that check.
Before this change we were setting the headers on the PUT
request for normal and multipart uploads. For normal uploads this caused the error
403 Forbidden: There were headers present in the request which were not signed
After this fix we set the headers in the object upload request itself
as the s3 SDK expects.
This means that we only support a limited range of headers
- Cache-Control
- Content-Disposition
- Content-Encoding
- Content-Language
- Content-Type
- X-Amz-Tagging
- X-Amz-Meta-
Note for the last of those are for setting custom metadata in the form
"X-Amz-Meta-Key: value".
This now works for multipart uploads and single part uploads

* s3: add `max_upload_parts` support

Before this change, attempting to upload a single file into an s3
bucket which did not have create permission gave AccessDenied: Access
Denied error when it tried to create the bucket.
This was masked until e2bf91452a was
fixed.
This fix marks the bucket as OK if a fetch on an object indicates it
is OK. This stops rclone thinking it has to create the bucket in the
first place.
Fixes#4297
Previously we had a map of pools for different chunk sizes.
In practice the mapping is not very useful and requires a lock.
Pools of size other that ChunkSize can only happen when we have a huge file (over 10k * ChunkSize).
We need to have a bunch of identically sized huge files.
In such case most likely ChunkSize should be increased.
The mapping and its lock is replaced with a single initialised pool for ChunkSize, in other cases pool is allocated and freed on per file basis.
In 5470d34740 "backend/s3: use low-level-retries as the number
of SDK retries" we switched over to using the AWS SDK low level
retries instead of rclone's low level retry logic.
This had the unfortunate attempt that retrying listings to correct XML
Syntax errors failed on non S3 backends such as CEPH. The AWS SDK was
also retrying the XML Syntax error request which doesn't make sense.
This change turns off the AWS SDK retries in favour of just using
rclone's retry logic.
Amazon S3 is built to handle different kinds of workloads.
In rare cases where S3 is not able to scale for whatever reason users
will face status 500 errors.
Main mechanism for handling these errors are retries.
Amount of needed retries varies for each different use case.
This change is making retries for s3 backend configurable by using
--low-level-retries option.
Currently each multipart upload allocated his own buffers, which after
file upload was garbaged. Next files couldn't leverage already allocated
memory which resulted in inefficent memory management. This change
introduces backend memory pool keeping memory chunks which can be
used during object operations.
Fixes#3967
The error code 500 Internal Error indicates that Amazon S3 is unable to handle the request at that time. The error code 503 Slow Down typically indicates that the requests to the S3 bucket are very high, exceeding the request rates described in Request Rate and Performance Guidelines.
Because Amazon S3 is a distributed service, a very small percentage of 5xx errors are expected during normal use of the service. All requests that return 5xx errors from Amazon S3 can and should be retried, so we recommend that applications making requests to Amazon S3 have a fault-tolerance mechanism to recover from these errors.
https://aws.amazon.com/premiumsupport/knowledge-center/http-5xx-errors-s3/
The S3 ListObject API returns paginated bucket listings, with
"MaxKeys" items for each GET call.
The default value is 1000 entries, but for buckets with millions of
objects it might make sense to request more elements per request, if
the backend supports it. This commit adds a "list_chunk" option for
the user to specify a lower or higher value.
This commit does not add safe guards around this value - if a user
decides to request a too large list, it might result in connection
timeouts (on the server or client).
In AWS S3, there is a fixed limit of 1000, some other services might
have one too. In Ceph, this can be configured in RadosGW.
