Set this automatically for any backend which implements UnWrap and
manually for combine and union which can't implement UnWrap but do
overlay other backends.
Before this change, the Pikpak backend would always download
the first media item whenever possible, regardless of whether
or not it was the original contents.
Now we check the validity of a media link using the `fid`
parameter in the link URL.
Fixes#6992
Before this change the pikpak backend changed the global
--multi-thread-streams flag which wasn't desirable.
Now the machinery is in place to use the NoMultiThreading feature flag
instead.

Some servers return a 501 error when using MLST on a non-existing
directory. This patch allows it.
I don't think this is correct usage according to the RFC, but the RFC
doesn't explicitly state which error code should be returned for
file/directory not found.
Before this fix a blank line in the MLST output from the FTP server
would cause the "unsupported LIST line" error.
This fixes the problem in the upstream fork.
Fixes#6879
Implement a Partialuploads feature flag to mark backends for which
uploads are not atomic.
This is set for the following backends
- local
- ftp
- sftp
See #3770
Before this change rclone used a normal SFTP rename if present to
implement Move.
However the normal SFTP rename won't overwrite existing files.
This fixes it to either use the POSIX rename extension
("posix-rename@openssh.com") or to delete the source first before
renaming using the normal SFTP rename.
This isn't normally a problem as rclone always removes any existing
objects first, however to implement non --inplace operations we do
require overwriting an existing file.
This also produces a warning when rclone detects files have been
blocked because of virus content
server reports this file is infected with a virus - use --onedrive-av-override to download anyway
Fixes#557
Before this change, when Object.Update was called in the drive
backend, it overwrote the remote with that of the object info.
This is incorrect - the remote doesn't change on Update and this patch
fixes that and introduces a new test to make sure it is correct for
all backends.
This was noticed when doing Update of objects in a nested combine
backend.

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.

Before this change, drive would mistakenly identify a folder with a
training slash as a file when passed to NewObject.
This was picked up by the integration tests
In an earlier patch
d5afcf9e34 crypt: try not to return "unexpected EOF" error
This introduced a bug for 0 length files which this fixes which only
manifests if the io.Reader returns data and EOF which not all readers
do.
This was failing in the integration tests.
Before this change using /path/to/file.rclonelink would not find the
file when using -l/--links.
This fixes the problem by doing another stat call if the file wasn't
found without the suffix if -l/--links is in use.
It will also give an error if you refer to a symlink without its
suffix which will not work because the limit to a single file
filtering will be using the file name without the .rclonelink suffix.
need ".rclonelink" suffix to refer to symlink when using -l/--links
Before this change it would use the symlink as a directory which then
would fail when listed.

This changes crypt's use of sync.Pool: Instead of storing slices
it now stores pointers pointers fixed sized arrays.
This issue was reported by staticcheck:
SA6002 - Storing non-pointer values in sync.Pool allocates memory
A sync.Pool is used to avoid unnecessary allocations and reduce
the amount of work the garbage collector has to do.
When passing a value that is not a pointer to a function that accepts
an interface, the value needs to be placed on the heap, which means
an additional allocation. Slices are a common thing to put in sync.Pools,
and they're structs with 3 fields (length, capacity, and a pointer to
an array). In order to avoid the extra allocation, one should store
a pointer to the slice instead.
See: https://staticcheck.io/docs/checks#SA6002
This change provides the ability to pass `env_auth` as a parameter to
the drive provider. This enables the provider to pull IAM
credentials from the environment or instance metadata. Previously if no
auth method was given it would default to requesting oauth.
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
To differentiate the new hasMESHA1 quirk, the existing hasMD5 and hasSHA1
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:
a61d219bc local: fix -L/--copy-links with filters missing directories
Then fixed in:
8d1fff9a8 local: obey file filters in listing to fix errors on excluded files
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
remain using QuickXorHash as before.
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
multipart upload ETag at all. However the ETag is returned in 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
code was wrong.
This means that users of the gov version of Alibaba will have to add
`list_version 1` to their config files.

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.
This commit switches from using the old Azure go modules

This stops rclone using deprecated code and enables the full range of
authentication with Azure.

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.
See: https://forum.rclone.org/t/not-encrypting-or-compressing-before-upload/32261/10
Before this change we were putting connections into the connection

This meant that when the operation had finished the context was
cancelled and the connection became unusable.

Before this change, when using -server-side-across-configs rclone
would direct Move/Copy/DirMove to the destination server.

unclear in the RFC, but the name of the parameter "Destination:" seems
clear and this is how dCache and Rucio have implemented it.

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

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.

In https://github.com/jlaffaye/ftp/commit/212daf295f the upstream FTP
library changed the way adding your own dialer works which meant that

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.
See: https://forum.rclone.org/t/metadata-update-local-s3/32277/7
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.
See #2658
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.
