Before this change, change notify would pick up files which were
shared with us as well as file within the drive.
When using an encrypted mount this caused errors like:
ChangeNotify was unable to decrypt "Plain file name": illegal base32 data at input byte 5
The fix tells drive to restrict changes to the drive in use.
Fixes#6771
Before this change the code wasn't taking into account the error
io.ErrUnexpectedEOF that io.ReadFull can return properly. Sometimes
that error was being returned instead of a more specific and useful
error.
To fix this, io.ReadFull was replaced with the simpler
readers.ReadFill which is much easier to use correctly.
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.
When using ssh-agent to hold multiple keys, it is common practice to configure
openssh to use a specific key by setting the corresponding public key as
the `IdentityFile`. This change makes a similar behavior possible in rclone
by having it parse the `key_file` config as the public key when
`key_use_agent` is `true`.
rclone already attempted this behavior before this change, but it assumed that
`key_file` is the private key and that the public key is specified in
`${key_file}.pub`. So for parity with the openssh behavior, this change makes
rclone first attempt to read the public key from `${key_file}.pub` as before
(for the sake of backward compatibility), then fall back to reading it from
`key_file`.
Fixes#6791
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
This provider:
- supports the `X-OC-Mtime` header to set the mtime
- calculates SHA1 checksum server side and returns it as a `ME:sha1hex` prop

quirks for Owncloud have been renamed to hasOCMD5 and hasOCSHA1.
Fixes#6837
Sometimes vsftpd returns a 426 error when closing the stream even when
all the data has been transferred successfully. This is some TLS
protocol mismatch.
Rclone has code to deal with this already, but the error returned from
Close was wrapped in a multierror so the detection didn't work.
This properly extract `textproto.Error` from the errors returned by
`github.com/jlaffaye/ftp` in all the cases.

Before this fix, a dangling symlink was erroring the sync. It was
writing an ERROR log and causing rclone to exit with an error. The
List method wasn't returning an error though.
This fix makes sure that we don't log or report a global error on a
file/directory that has been excluded.
This feature was first implemented in:

This commit also adds test cases for the failure modes of those commits.
See #6376
Before this change, if a "--drive-stop-on-upload-limit" was set,
rclone would not stop the upload if a "storageQuotaExceeded" error occurred.
This fix now checks for the "storageQuotaExceeded" error
and "--drive-stop-on-upload-limit", and fails fast.
This change provides the ability to pass `env_auth` as a parameter to
the google cloud storage provider. This enables the provider to pull IAM

Before this change the hash used for Onedrive Personal was SHA1. From
July 2023 Microsoft is phasing out SHA1 hashes in favour of
QuickXorHash in Onedrive Personal. Onedrive Business and Sharepoint

This choice can be changed using the --onedrive-hash-type flag (and
config option) so that SHA1 can be selected while it is still
available in the transition period.

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.

Before this change if --s3-no-head was in use rclone didn't check the

use, otherwise it uses the ETag from a fresh HEAD request.

Uploading 100 files of each 1 MB took 20 seconds before. With above fix it takes around 2 seconds now.
10x time improvement in line with pacer's sleep reduction from 100ms to 10ms
Before this change when uploading files bigger than 1TiB, the chunk
calculator would work out that the chunk size needed to be bigger than
the default 100 MiB to fit within the 10,000 parts limit.
However the uploader was still using the memory pool for the old chunk
size and this caused errors like
panic: runtime error: slice bounds out of range [:122683392] with capacity 100663296
The fix for this is to make a temporary pool with the larger chunk
size and use it during the upload of the large file.

Before this change we were sending webdav requests to the go http

caused the tests to fail.
The test has been changed to properly mock up an About query and

Passwords for encrypted libraries are kept in memory in the server
and flushed after an hour.
This MR fixes an issue when the library password expires after 1 hour.
rclone sync erroneously deleted folders renamed to a different case on
crypts where directory name encryption was disabled and the underlying
remote was case insensitive.
Example: Renaming the folder Test to tEST before a sync to a crypt having
remote=OneDrive:crypt and directory_name_encryption=false could result in
the folder and all its content being deleted. The following sync would
correctly create the tEST folder and upload all of the content.
Additional tests have revealed other potential issues when using
filename_encryption=off or directory_name_encryption=false on case
insensitive remotes. The documentation has been updated to warn about
potential problems when using these combinations.
This error was caused by rclone supplying an empty
`x-ms-blob-public-access:` header when creating a container for
private access, rather than omitting it completely.
This is a valid way of specifying containers should be private, but if
the storage account has the flag "Blob public access" unset then it
gives "409 Public access is not permitted on this storage account".
This patch fixes the problem by only supplying the header if the
access is set.
Fixes#6645
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.
See: https://forum.rclone.org/t/s3-and-intermittent-403-errors-with-file-renames-and-drag-and-drop-operations-in-windows-explorer/34773
This patch implements --use-server-modtime for the Azureblob backend.
It does this by not reading the time from the metadata if the global
flag is set.
When the SDK was upgraded it started delivering metadata where the
keys were not in lower case as per the old SDK.
Rclone normalises the case of the keys for storage in the Object, but
the directory marker check was being done with the unnormalised keys
as it needs to be done before the Object is created.
This fixes the directory marker check to do a case insensitive compare
of the metadata keys.
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

And rationalises the auth order.
Normally rclone will check the container exists before uploading if it
hasn't listed the container yet.
Often rclone will be running with a limited set of permissions which
means rclone can't create the container anyway, so this stops the
check.
This will save a transaction.

Before this fix a chain compress -> crypt -> s3 was giving errors
BadDigest: The Content-MD5 you specified did not match what we received.
This was because the crypt backend was encrypting the underlying local
object to calculate the hash rather than the contents of the metadata
stream.
It did this because the crypt backend incorrectly identified the
object as a local object.
This fixes the problem by making sure the crypt backend does not
unwrap anything but fs.OverrideRemote objects.

Before this change we were putting connections into the connection

8d1fff9a82 local: obey file filters in listing to fix errors on excluded files
We introduced the concept of local backend filters.
Unfortunately the filters were being applied before we had resolved
the symlink to point to a directory. This meant that symlinks pointing
to directories were filtered out when they shouldn't have been.
This was fixed by moving the filter check until after the symlink had
been resolved.

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.

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 change rclone used statx() to read the metadata for files
from the local filesystem when `-M` was in use.
Unfortunately statx() was only introduced in kernel 4.11 which was
released in April 2017 so there are current systems (eg Centos 7)
still on kernel versions which don't support statx().
This patch checks to see if statx() is available and if it isn't, it
falls back to using fstatat() which was introduced in Linux 2.6.16
which is guaranteed for all Go versions.

This patch reworks our connection code to bring it into the
expectations of the library.
Before this fix, if an error ocurred reading the metadata, it could be
set as nil and then used, causing a crash.
This fix changes the readMetadata function so it returns an error, and
the error is always set if the metadata returned is nil.
If mkdir fails then before this change it would have thrown an
error.
After this change, if the error indicated that the directory
already exists then the error is not returned to the user.
This fixes a race condition when two rclone threads are trying to
create the same directory.
In this commit
8d1fff9a82 local: obey file filters in listing to fix errors on excluded files
We started using filters in the local backend so the user could short
circuit troublesome files/directories at a low level.
However this caused a number of integration tests to fail. This turned
out to be in backends wrapping the local backend. For example the
combine backend test failed because it changes the paths passed to the
local backend so they no longer match the paths in the current filter.
To fix this, a new feature flag `FilterAware` was added and the
UseFilter context flag is only passed to backends which support it. As
the wrapping backends don't support the flag, this fixes the problems
in the integration tests.
In future the wrapping backends could modify the active filters to
match the path modifications and then they could set the FilterAware
flag.
See #6376
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 rclone was run with `-M` on a filesystem
without xattr support, it would error out.
This patch makes rclone detect the not supported errors and disable
xattrs from then on. It prints one ERROR level message about this.

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.

Before this fix, the dropbox backend wasn't decoding the file names
received in changenotify events into rclone standard format.
This meant that changenotify events for filenames which had encoded
characters were failing to be decrypted properly if wrapped in crypt.
See: https://forum.rclone.org/t/rclone-vfs-cache-says-file-name-too-long/31535
Before this patch backends could be shutdown when they fell out of the
cache when they were in use with combine. This was particularly
noticeable with the dropbox backend which gave this error when
uploading files after the backend was Shutdown.

Previously, with standard auth, the username would be stored in config - but only after
entering the non-standard device/mountpoint sequence during config (a feature introduced
with #5926). Regardless of that, rclone always requests the username from the api at
startup (NewFS).
In #6270 (commit 9dbed02329) this was changed to always
store username in config (consistency), and then also use it to avoid the repeated
customer info request in NewFs (performance). But, as reported in #6309, it did not work
with legacy auth, where user enters username manually, if user entered an email address
instead of the internal username required for api requests. This change was therefore
recently reverted.
The current commit takes another step back to not store the username in config during
the non-standard device/mountpoint config sequence (consistentcy). The username will
now only be stored in config when using legacy auth, where it is an input parameter.
Extend the shouldRetry function by also checking for the quotaExceeded
reason, and since this function appeared to be untested, add a test case
for the existing errors and this new one.

`FS.cacheExpiry` is accessed through sync/atomic.
According to the documentation, "On ARM, 386, and 32-bit MIPS, it is
the caller's responsibility to arrange for 64-bit alignment of 64-bit
words accessed atomically. The first word in a variable or in an
allocated struct, array, or slice can be relied upon to be 64-bit
aligned."
Before commit 1d2fe0d856 this field was
aligned, but then a new field was added to the structure, causing the
test suite to panic on linux/386.
No other field is used with sync/atomic, so `cacheExpiry` can just be
placed at the beginning of the stuct to ensure it is always aligned.
By default these will be downloaded compressed.
This changes the default of the previous commit
2781f8e2f1 gcs: Fix download of "Content-Encoding: gzip" compressed objects
But will fit in better with the metadata framework when copying
gzip-encoded objects from backend to backend.
Existing version did save username in config, but only when entering the custom
device/mountpoint sequence in config. Regardless of that, it did always look up the
username at startup with an api request.
This commit improves it so that the username will always be stored in config,
and when using standard authentication it picks it from the login token instead of
requesting it from the remote api, and also in fs constructor it picks it from config
instead of requesting it from remote api (again).
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.
Before this fix GetFreeSpace returned math.MaxInt64 for remotes which
don't support reading free space, however this is used in various
comparison routines as a too large value, meaning that remotes of size
math.MaxInt64 were never being selected.
This fixes GetFreeSpace to return math.MaxInt64 - 1 so then can be selected.
It also fixes GetUsedSpace the same way however as the default for not
supported was 0 this was very unlikely to have ever caused a problem.

Before this fix, if uploading to a union consisting of all bucket
based remotes (eg s3), uploads failed with:
Failed to copy: object not found
This was because the union backend was relying on parent directories
being created to work out which files to upload. If all the upstreams
were bucket based backends which can't hold empty directories, no
directories were created and the upload failed.
This fixes the problem by returning the upstreams used when creating
the directory for the upload, rather than searching for them again
after they've been created.
This will also make the union backend a little more efficient.

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.

implementation) uses format from golang's time.RFC3339 constant. Uploads (using the
allocate api) uses format from a hard coded constant with value identical to golang's
time.RFC3339. And then we have the classic JFS time format, which is similar to RFC3339
but not identical, using a different constant. Also the naming is a bit confusing,
since the term api is used both as a generic term and also as a reference to the
newer format used in the api subdomain where the allocate endpoint is located.
This commit refactors these things a bit.
Now using the utility function for deduplication that was newly implemented to
fix an issue with server-side copy. This function uses the original, and generic,
"jfs" api (and its "cphash" feature), instead of the newer "allocate" api dedicated
for uploads. Both apis support similar deduplication functionaly that we rely on for
the SetModTime operation. One advantage of using the jfs variant is that the allocate
api is specialized for uploads, an initial request performs modtime-only changes and
deduplication if possible but if not possible it creates an incomplete file revision
and returns a special url to be used with a following request to upload missing content.
In the SetModTime function we only sent the first request, using metadata from existing
remote file but different timestamps, which lead to a modtime-only change. If, for some
reason, this should fail it would leave the incomplete revision behind. Probably not
a problem, but the jfs implementation used with this commit is simpler and
a more "standalone" request which either succeeds or fails without expecting additional
requests.
A strange feature (probably bug) in the api used by the server-side copy implementation
in Jottacloud backend is that if the destination file is in trash, the copy request
succeeds but the destination will still be in trash! When this situation occurs in
rclone, the copy command will fail with "Failed to copy: object not found" because
rclone verifies that the file info in the response from the copy request is valid,
and since it is marked as deleted it is treated as invalid.
This commit works around this problem by looking for this situation in the response
from the copy operation, and send an additional request to a built-in deduplication
endpoint that will restore the file from trash.
Fixes#6112
The existing code in rclone set the value "offline_access+openid",
when encoded in body it will become "offline_access%2Bopenid". I think
this is wrong. Probably an artifact of "double urlencoding" mixup -
either in rclone or in the jottacloud cli tool version it was sniffed
from? It does work, though. The token received will have scopes "email
offline_access" in it, and the same is true if I change to only
sending "offline_access" as scope.
If a proper space delimited list of "offline_access openid"
is used in the request, the response also includes openid scope:
"openid email offline_access". I think this is more correct and this
patch implements this.
See: #6107
Adds a configuration option to the GCS backend to allow skipping the
check if a bucket exists before copying an object to it, much like
f406dbb added for S3.
Before this change the cache backend was passing -1 into
rate.NewLimiter to mean unlimited transactions per second.
In a recent update this immediately returns a rate limit error as
might be expected.
This patch uses rate.Inf as indicated by the docs to signal no limits
are required.
Before this change the 206 responses from putio Range requests were being
returned as errors.
This change checks for 200 and 206 in the GET response now.
Before this fix, rclone retries chunks of multipart uploads. However
if they had been partially received dropbox would reply with an
incorrect_offset error which rclone was ignoring.
This patch parses the new offset from the error response and uses it
to adjust the data that rclone sends so it is the same as what dropbox
is expecting.
See: https://forum.rclone.org/t/dropbox-rate-limiting-for-upload/29779
This commit switches Google Cloud Storage from the drive pacer to the
s3 pacer. The main difference between them is that the s3 pacer does
not limit transactions in the non-error case. This is appropriate for
a cloud storage backend where you pay for each transaction.
Before this fix `NewObject` could return a wrapped `fs.Object(nil)`
which caused a crash. This was caused by `wrapObject` returning a
`nil` `*Object` which was cast into an `fs.Object`.
This changes the interface of `wrapObject` so it returns an
`fs.Object` instead of a `*Object` and an error which must be checked.
This forces the callers to return a `nil` object rather than an
`fs.Object(nil)`.

Having a replace directive in go.mod causes "go get
github.com/rclone/rclone" to fail as it discussed in this Go issue:
https://github.com/golang/go/issues/44840
This is apparently how the Go team want go.mod to work, so this commit
hard forks github.com/jlaffaye/ftp into github.com/rclone/ftp so we
can remove the `replace` directive from the go.mod file.
Fixes#5810
Before this change rclone send pre-1970 timestamps as negative
numbers. pCloud ignores these and sets them as todays date.
This change sends the timestamps as unsigned 64 bit integers (which is
how the binary protocol sends them) and pCloud accepts the (actually
negative) timestamp like this.
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 `rclone about swift:container` would show aggregate
info about all the containers, not just the one in use.
This causes a problem if container listing is disabled (for example in
the Blomp service).
This fix makes `rclone about swift:container` show only the info about
the given `container`. If aggregate info about all the containers is
required then use `rclone about swift:`.

Before this change, rclone supported authorizing for remote systems by
going to a URL and cutting and pasting a token from Google. This is
known as the OAuth out-of-band (oob) flow.
This, while very convenient for users, has been shown to be insecure
and has been deprecated by Google.
https://developers.googleblog.com/2022/02/making-oauth-flows-safer.html#disallowed-oob
> OAuth out-of-band (OOB) is a legacy flow developed to support native
> clients which do not have a redirect URI like web apps to accept the
> credentials after a user approves an OAuth consent request. The OOB
> flow poses a remote phishing risk and clients must migrate to an

This change disables that flow, and forces the user to use the
redirect URL flow. (This is the flow used already for local configs.)
In practice this will mean that instead of cutting and pasting a token
for remote config, it will be necessary to run "rclone authorize"
instead. This is how all the other OAuth backends work so it is a well
tested code path.

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.
Before this change attempting NewObject on a SAS URL's root would
crash the Azure SDK.
This change detects that using the code from this previous fix
f7404f52e7 azureblob: fix crash when listing outside a SAS URL's root - fixes#4851
And returns not object not found instead.
It also prevents things being uploaded to the root of the SAS URL
which also crashes the Azure SDK.
Before this fix if a file was updated, but to the same length and
timestamp then the local backend would return the wrong (cached)
hashes for the object.
This happens regularly on a crypted local disk mount when the VFS
thinks files have been changed but actually their contents are
identical to that written previously. This is because when files are
uploaded their nonce changes so the contents of the file changes but
the timestamp and size remain the same because the file didn't
actually change.
This causes errors like this:
ERROR: file: Failed to copy: corrupted on transfer: md5 crypted
hash differ "X" vs "Y"
This turned out to be because the local backend wasn't clearing its
cache of hashes when the file was updated.
This fix clears the hash cache for Update and Remove.
It also puts a src and destination in the crypt message to make future
debugging easier.
Fixes#4031
Currently the B2 docs don't specify which format the download_url

After speed testing it was discovered that upload speed goes up pretty
much linearly with upload concurrency. This patch changes the default
from 4 to 16 which means that rclone will use 16 * 4M = 64M per
transfer which is OK even for low memory devices.
This adds a note that performance may be increased by increasing
upload concurrency.
See: https://forum.rclone.org/t/performance-of-rclone-vs-azcopy/27437/9
Previously only the fs being checked on gets passed to
GetModifyWindow(). However, in most tests, the test files are
generated in the local fs and transferred to the remote fs. So the
local fs time precision has to be taken into account.
This meant that on Windows the time tests failed because the
local fs has a time precision of 100ns. Checking remote items uploaded
from local fs on Windows also requires a modify window of 100ns.
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.
The API doesn't seem to accept a value of "0" any more for the root
directory ID, giving the error "Could not decode folder id".
However omitting it seems to work fine.
In this commit, released in 1.56.0 we started reading the size of the

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:

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.

The API has changed in the directory move call JSON response from
returning a TaskID as a string to returning it as an integer. In other
places it is still returned as a string though.
This patch allows the TaskID to be an integer or a string in the JSON
response and keeps it internally as a string like before.
Before this change the backoff for the error_background error was 6
seconds. This means that if it wasn't resolved in 60 seconds (with the
default 10 low level retries) then an error was reported.
This error was being reported frequently in the integration tests, so
is likely affecting real users too.
This patch changes the backoff into an exponential backoff
1,2,4,8...1024 seconds to make sure we wait long enough for the
background operation to complete.

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.
Before this change the cleanup routine exited on the first deletion
error.
This change counts any errors on deletion and exits when the iteration
is complete with an error showing the number of deletion failures.
Deletion failures will be logged.
Before this change we uses limit/offset paging for directories in the
main directory listing routine and in the trash cleanup listing.
This switches to the new scheme of limit/marker which is more reliable
on a directory which is continuously changing. It has the disadvantage
that it doesn't tell us the total number of items available, however
that wasn't information rclone uses.
This changes the interface to NewObject so that if NewObject is called
on a directory then it should return fs.ErrorIsDir if possible without
doing any extra work, otherwise fs.ErrorObjectNotFound.

go run integration-test.go -tests backend -run TestIntegration/FsMkdir/FsPutFiles/FsNewObjectDir -branch fix-stat -maxtries 1
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 patch the md5all option would skip creating metadata with
hashsum if base filesystem provided md5, in hope to pass it through.
However, if base hash is slow (for example on local fs), chunker passed
slow md5 but never reported this fact in features.
This patch makes chunker snapshot base hashsum in metadata when md5all is
set and base hashsum is slow since chunker was intended to provide only
instant hashsums from the start.

I discovered that `rclone` always upload in chunks of 16MiB whenever
uploading a file smaller than `--drive-upload-cutoff`. This is
undesirable since the purpose of the flag `--drive-upload-cutoff` is
to *prevent* chunking below a certain file size.
I realized that it wasn't `rclone` forcing the 16MiB chunks. The
`google-api-go-client` forces a chunk size default of
[`googleapi.DefaultUploadChunkSize`](32bf29c2e1/googleapi/googleapi.go (L55-L57))
bytes for resumable type uploads. This means that all requests that
use `*drive.Service` directly for upload without specifying a
`googleapi.ChunkSize` will be forced to use a *`resumable`*
`uploadType` (rather than `multipart`) for files less than
`googleapi.DefaultUploadChunkSize`. This is also noted directly in the
Drive API client documentation [here](https://pkg.go.dev/google.golang.org/api/drive/v3@v0.44.0#FilesUpdateCall.Media).
This fixes the problem by passing `googleapi.ChunkSize(0)` to
`Media()` method calls, which is the only way to disable chunking
completely. This is mentioned in the API docs
[here](https://pkg.go.dev/google.golang.org/api/googleapi@v0.44.0#ChunkSize).
The other alternative would be to pass
`googleapi.ChunkSize(f.opt.ChunkSize)` -- however, I'm *strongly* in
favor of *not* doing this for performance reasons. By not explicitly
passing a `googleapi.ChunkSize(0)`, we effectively allow
[`PrepareUpload()`](https://pkg.go.dev/google.golang.org/api/internal/gensupport@v0.44.0#PrepareUpload)
to create a
[`NewMediaBuffer`](https://pkg.go.dev/google.golang.org/api/internal/gensupport@v0.44.0#NewMediaBuffer)
that copies the original `io.Reader` passed to `Media()` in order to
check that its size is less than `ChunkSize`, which will unnecessarily
consume time and memory.
`minChunkSize` is also changed to be `googleapi.MinUploadChunkSize`,
as it is something specified we have no control over.
Google Drive API allows for clauses like "modifiedTime > '2012-06-04T12:00:00'"
in the query param, so the filter flags --max-age and --min-age can be applied
directly at the directory listing phase rather than in a filter.
This is extremely helpful when we want to do an incremental backup of a remote
drive with many files but the number of recently changed file is small.

This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error

mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Before this change the union's feature flags were a strict AND of the
underlying remotes. This means that a union of a local disk (which can
Move but not Copy) and a bucket based remote (which can Copy but not
Move) could neither Move nor Copy.
This fix advertises Move in the union if all the remotes can Move or
Copy. It also implements Move as Copy+Delete (like rclone does
normally) if the underlying union does not support Move.
This enables renames to work with unions of local disk and bucket
based remotes expected.

94dbfa4ea fs: change Config callback into state based callback #3455
This passed the password as a temporary config parameter but forgot to
reveal it in the API call.
At some point some google docs files started having sizes returned in
their listing information.
This then caused rclone to treat the docs as files which caused
downloads to fail.
The API docs now state that google docs may have sizes (whereas I'm
pretty sure it didn't earlier).
This fix removes the check for size, so google docs are identified
solely by not having an MD5 checksum.
This change fixes the bug described below:
if a file is removed while the local backend List() runs,
the call will flag an accounting error.
The bug manifests itself if local backend is the Sync target
due to intrinsic concurrency.
The odds to hit this bug depend on --checkers and --transfers.
Chunker over local backend is affected even more because
updating a composite object with a smaller size content
translates into removing chunks on the underlying file system
and involves a number of List() calls.
- Unify all hash names as lowercase alphanumerics without punctuation.
- Legacy names continue to work but disappear from docs, they can be depreciated or dropped later.
- Make rclone hashsum print supported hash list in case of wrong spelling.
- Update documentation.

This is a very large change which turns the post Config function in

It was discovered on some Android systems, the stat size of a symlink
is different to the size that readlink returns.
This was giving errors like this
transport connection broken: http: ContentLength=30 with Body length 28
There are enough exceptions to the size of readlink being different to
the size of stat that this patch now always does readlink to work out
the size of a symlink.
Since symlinks are relatively uncommon this shouldn't affect
performance too much and will mean that the size is always correct.
This deprecates the --local-zero-size-links flag which is now
effectively always enabled.

v1.4.6 of uplink allows us to do a negative offset from the end of the
file. This removes a round trip when requesting the last N bytes of a
file.
Previous to v1.4.6 of uplink it wasn't possible to do a negative offset
on download. This meant that to fulfill the semantics of http range
headers it was necessary to first fetch the size of the object via a
stat call and compute absolute offset and length.
Restructuring of config code in v1.55 resulted in config
file being loaded early at process startup. If configuration
file is encrypted this means user will need to supply the password,
even when running commands that does not use config.
This also lead to an issue where mount with --deamon failed to
decrypt the config file when it had to prompt user for passord.

Including the bucket name as part of the `fileNamePrefix` passed to
`b2_get_download_authorization` results in a link valid for objects that
have the bucket name as part of the object path; e.g.,
rclone link :b2:some-bucket/some-file
would result in a public link valid for the object
`some-bucket/some-file` in the `some-bucket` bucket (in rclone-remote
parlance, `:b2:some-bucket/some-bucket/some-file`). This will almost
certainly result in a broken link.
The B2 docs don't explicitly specify this behavior, but the example
given for `fileNamePrefix` provides some clarification.

Betweeen rclone v1.54 and v1.55 there was an approx 3x performance
regression when transferring to distant SFTP servers (in particular
rsync.net).
This turned out to be due to the library github.com/pkg/sftp rclone
uses. Concurrent writes used to be enabled in this library by default
(for v1.12.0 as used in rclone v1.54) but they are no longer enabled
(for v1.13.0 as used in rclone v1.55) for safety reasons and it is
necessary to enable them specifically.
The safety concerns are due to the uncertainty as to whether writes
come in order and whether a half completed file might have holes in
it. This isn't a problem for rclone since a) it doesn't restart
uploads and b) it has a post-transfer checksum test.
This change introduces a new flag `--sftp-disable-concurrent-writes`
to control the feature which defaults to false, meaning that
concurrent writes are enabled as in v1.54.
However this isn't quite enough to fix the problem as the sftp library
needs to be able to sniff the size of the stream from the reader
passed in, so this also adds a `Size` interface to the reader to
enable this. This involved a patch to the library.
The library was reverted to v1.12.0 for v1.55.1 - this patch installs
v1.13.0+master to fix the Size interface problem.
See: https://github.com/pkg/sftp/issues/426
Before this change, rclone checked to see if an object existed before
doing an upload by listing the destination directory. This was very
inefficient, especially with large directories.
After this change rclone uses the pre upload check API call which
checks to see if it is OK to upload an object, and also returns the ID
of an existing object which saves rclone having to do a directory
listing.
OneDrive randomly returns the error message: "InvalidAuthenticationToken: Unable to initialize RPS". These unexpected errors typically caused the entire rclone command to fail.
This work around recognizes these errors and marks them for a low level retry, that mostly succeeds. This will make rclone commands complete without being noticeable affected.

Fixes#5210
