Before this change PartialUploads was not set. This is clearly wrong
since incoming files are visible on the smb server.
Setting PartialUploads fixes the multithread upload modtime problem as
it uses the PartialUploads flag as an indication that it needs to set
the modtime explicitly.
This problem was detected by the new TestMultithreadCopy integration
tests
Fixes#7411
Before this change smb drives sometimes showed a fraction of the
correct size using `rclone about`.
This fixes the problem by switching the upstream library from
github.com/hirochachacha/go-smb2 to github.com/cloudsoda/go-smb2 which
has a fix for the problem.
The new library passes the integration tests.
Fixes#6733
Before this change, streaming files an exact multiple of the chunk
size would cause rclone to attempt to stream a 0 sized chunk which was
rejected by the b2 servers.
This bug was noticed by the new integration tests for chunked streaming.
Before this change the b2 servers would complain as this was only a
single part transfer.
This was noticed by the new integration tests for server side chunked copy.
This commit fixed the problem but made the integration tests fail.
33376bf399 dropbox: fix missing encoding for rclone purge
This fixes the problem properly by making sure we send the encoded or
non encoded root to the right places.
Before this change, the drive backend only used metadata if it was
created with Metadata enabled.
This patch changes it so the Metadata support is enabled dynamically
if it is set in the context.
This fixes the metadata tests in the integration tests which have been
changed to make sure Metadata is enabled.
Google drive doesn't allow the btime (created time) metadata to be
updated when updating an existing object.

Users can now input a comma separated list of namenodes when writing
config for hdfs remotes.
This is required when you have multiple namenodes in your hdfs cluster
and cannot be certain which namenodes will be in 'standby' or 'active'
states.
This was available before but wasn't documented and didn't use the
correct rclone interfaces.
On a 404 error, b2 returns an empty body which, before this change,
caused the error handler to try to parse an empty string and give the
following DEBUG message:
Couldn't decode error response: EOF
This is confusing as it is expected in normal operations and isn't an
error.
This change reads the body of an error response first then tries to
decode it only if it isn't empty, which avoids the confusing DEBUG
message.
This also upgrades failure to read the body or failure to decode the
JSON to ERROR messages as now we are certain that we should have
something to read and decode.
For some files the Windows Volume Shadow Service (VSS) advertises the
file size as X in the directory listing but returns a different number
Y on stat-ing the file. If the file is opened and read there are Y
bytes available for reading.
Existing copy tools copy Y bytes rather than X so for consistency
rclone should do the same.
This fixes the problem by stat-ing the file immediately before opening
it. This will also reduce the unnecessary occurrence of "can't copy -
source file is being updated" errors; if the file has finished
changing by the time we come to copy it then we now can copy it
successfully.

Streaming uploads are used by rclone rcat and rclone mount
--vfs-cache-mode off.
After the multipart chunker refactor the multipart chunked streaming
upload was accidentally mixing the first and the second parts up which
was causing corrupted uploads.
This was caused by a simple off by one error in the refactoring where
we went from 1 based part number counting to 0 based part number
counting.
Fixing this revealed that the metadata wasn't being re-read for the
copied object either.
This fixes both of those issues and adds an integration tests so it
won't happen again.

Before this change if you tried to create a bucket that already
existed, but someone else owned then rclone did not return an error.
This now will return an error on providers that return the
AlreadyOwnedByYou error code or no error on bucket creation of an
existing bucket owned by you.
This introduces a new provider quirk and this has been set or cleared
for as many providers as can be tested. This can be overridden by the
--s3-use-already-exists flag.

Before this change, attempting to server side copy a google form would
give this error

Adding this flag allows the form to be server side copied but not

In v1.63 memory usage in the b2 backend was limited to `--transfers` *
`--b2-chunk-size`
However in v1.64 this was raised to `--transfers` * `--b2-chunk-size`
* `--b2-upload-concurrency`.
The default value for this was accidently set quite high at 16 which
means by default rclone could use up to 6.4GB of memory!
The new default sets a more reasonable (but still high) max memory of 1.6GB.
Before this change, the lock was held while the upload URL was being
fetched from the server.
This meant that any other threads were blocked from getting upload
URLs unecessarily.
It also increased the potential for deadlock.
Most useful is the addition of the file created timestamp, but also a timestamp for
when the file was uploaded.
Currently supporting a rather minimalistic set of metadata items, see PR #6359 for
some thoughts about possible extensions.
In this commit:
5f938fb9ed s3: fix "Entry doesn't belong in directory" errors when using directory markers
We checked that the remote has the prefix and then changed the remote
before removing the prefix. This sometimes causes:
panic: runtime error: slice bounds out of range [56:55]
The fix is to do the modification of the remote after removing the
prefix.
See: https://forum.rclone.org/t/cryptcheck-panic-runtime-error-slice-bounds-out-of-range/41977
Before this change the b2 backend listed all the buckets to turn a
single bucket name into an ID.
However in July 26, 2018 a parameter was added to the list buckets API
to make listing all the buckets unecessary.
This code sets the bucketName parameter so that only the results for
the desired bucket are returned.
The improved upload logic is active by default in uplink v1.12.0, so the
`testuplink.WithConcurrentSegmentUploadsDefaultConfig(ctx)` is not
required anymore.
See https://github.com/rclone/rclone/pull/7198
Before this change uploaded files could return the error "replication
in progress".
This error is harmless though and means the Close should be retried
which is what this patch does.
In this commit we discovered a problem with objects being uploaded to
the incorrect object name. It added an integration test for the
problem.
65b2e378e0 drive: fix incorrect remote after Update on object
This test was tripped by the hdfs backend and this patch fixes the
problem.
Sometimes opendrive reports "403 Folder is already deleted" on
directories which should exist.
This might be a bug in opendrive or in rclone however we work-around
here sufficient to get the tests passing.
ChangeNotify has been broken on the compress backend for a long time!
Before this change it was wrapping the file names received rather than
unwrapping them to discover the original names.
It is likely ChangeNotify was working adequately though for users as
the VFS just uses the directories rather than the file names.
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
Before this change, b2 would return an error when opening a link
generated by `rclone link`. The following error occurs when the object
path contains an ampersand that is not percent encoded:
{
"code": "bad_request",
"message": "Bad character in percent-encoded string: 38 (0x26)",
"status": 400
}
Before this change the box backend could make errors like
Error "not_found" (404): On-Behalf-Of User not found ([123 34 105 110
118 97 108 105 100 95 117 115 101 114 95 105 100 34 58 123 34 105 100
34 58 34 48 48 48 48 48 48 48 48 48 48 48 34 125 125])
This fixes it to produce this instead

This implements the OpenChunkWriter interface for b2 which
enables multi-thread uploads.
This makes the memory controls of the s3 backend inoperative; they are
replaced with the global ones.

As an extra security feature some FTP servers (eg FileZilla) require
that the data connection re-use the same TLS connection as the control
connection. This is a good thing for security.
The message "TLS session of data connection not resumed" means that it
was not done.
The problem turned out to be that rclone was re-using the TLS session
cache between concurrent connections so the resumed TLS data
connection could from any of the control connections.
This patch makes each TLS connection have its own session cache which
should fix the problem.
This also reverts the ftp library to the upstream version which now
contains all of our patches.
Fixes#7234
storj.io/uplink v1.11.0 comes with an improved logic for uploading large
files where file segments are uploaded concurrently instead of serially.
This allows to fully utilize the network connection during the entire
upload process.
This change enable the new upload logic.
The Swift backend does not always respect the flag telling it to skip
HEADing zero-length objects. This commit fixes that for ls/lsl/lsf.
Swift returns zero length for dynamic large object files when they're
included in a files lookup, which means that determining their size
requires HEADing each file that returns a size of zero. rclone's
--swift-no-large-objects instructs rclone that no large objects are
present and accordingly rclone should not HEAD files that return zero
length.
When rclone is performing an ls / lsf / lsl type lookup, however, it
continues to HEAD any zero length objects it encounters, even with
this flag set. Accordingly, this change causes rclone to respect the
flag in these situations.
NB: It is worth noting that this will cause rclone to incorrectly
report zero length for any dynamic large objects encountered with the
--swift-no-large-objects flag set.
Before this change, rclone always expected --sftp-path-override to be
the absolute SSH path to remote:path/subpath which effectively made it
unusable for wrapped remotes (for example, when used with a crypt
remote, the user would need to provide the full decrypted path.)
After this change, the old behavior remains the default, but dynamic
paths are now also supported, if the user adds '@' as the first
character of --sftp-path-override. Rclone will ignore the '@' and
treat the rest of the string as the path to the SFTP remote's root.
Rclone will then add any relative subpaths automatically (including
unwrapping/decrypting remotes as necessary).
In other words, the path_override config parameter can now be used to
specify the difference between the SSH and SFTP paths. Once specified
in the config, it is no longer necessary to re-specify for each
command.
See: https://forum.rclone.org/t/sftp-path-override-breaks-on-wrapped-remotes/40025
This allows using an external ssh binary instead of the built in ssh
library for making SFTP connections.
This makes another integration test target TestSFTPRcloneSSH:
Fixes#7012
Before this change we released the ssh connection back to the pool
before the upload was finished.
This meant that uploads were re-using the same ssh connection which
reduces throughput.
This releases the ssh connection back to the pool only after the
upload has finished, or on error state.

smb2.File implements the WriterAtCloser interface defined in
fs/types.go. Expose it via a OpenWriterAt method on
the fs struct to support multi-threaded writes.
The error is:

With the following additional debug information:
jwtutil: Response Body: {"error":"invalid_grant","error_description":"Please check the 'aud' claim. Should be a string"}
Problem is that in jwt-go the RegisteredClaims type has Audience field (aud claim) that
is a list, while box apparantly expects it to be a singular string. In jwt-go v4 we
currently use there is an alternative type StandardClaims which matches what box wants.
Unfortunately StandardClaims is marked as deprecated, and is removed in the
newer v5 version, so we this is a short term fix only.
Fixes#7114
Before this change the new partial downloads code was causing symlinks
to be copied as regular files.
This was because the partial isn't named .rclonelink so the local
backend saves it as a normal file and renaming it to .rclonelink
doesn't cause it to become a symlink.
This fixes the problem by not copying .rclonelink files using the
partials mechanism but reverting to the previous --inplace behaviour.
This could potentially be fixed better in the future by changing the
local backend Move to change files to and from symlinks depending on
their name. However this was deemed too complicated for a point
release.
This also adds a test in the local backend. This test should ideally
be in operations but it isn't easy to put it there as operations knows
nothing of symlinks.

Before this change if a directory entry could be listed but not
lstat-ed then rclone would give an error and abort the directory
listing with the error
failed to read directory entry: failed to read directory "XXX": lstat XXX
This change makes sure that the directory listing carries on even
after this kind of error.
The sync will be failed but it will carry on.
This problem was caused by a programming error setting the err
variable in an outer scope when it should have been using a local err
variable.

Before this change, if you mounted the root of the smb then it would
give an error on rclone about and periodically in the mount logs:
Statfs failed: bucket or container name is needed in remote
This fix makes the smb backend return empty usage in this case which
will stop the errors and show the default 1P of free space.

them.

This reverts commit 9065e921c1.
It turns out the problem for the failing fs/sync tests was the
policies being different for search and create which meant that the
file was being created in one union branch but a diferent one was
found in another branch.
The API seems to have changed and the `totalFileCount` item no longer
tracks the number of files in the directory so is useless for seeing
if the directory is empty.
This patch fixes the problem by seeing whether there are any files or
directories in the folder instead.
This problem was detected by the integration tests.
For some unknown reason the API sometimes returns the name already
exists on a server side copy.
{
"error_id": null,
"error_message": "Name already exist",
"error_type": "NAME_ALREADY_EXIST",
"error_uri": "http://api.put.io/v2/docs",
"extra": {},
"status": "ERROR",
"status_code": 400
}
This patch uploads to a temporary name then renames it which works
around the problem.
This was spotted by the integration tests.
The integration tests spotted that modification times are no longer
being preserved by the putio API in server side move and copy.
This patch explicitly sets the modtime after the server side move or
copy.
In this commit we enabled PartialUploads for the union backend.

This turns out to cause test failures in fs/sync so this commit
disables them again pending further investigation.
At some point the sharefile API changed to require the size of the
file in the initial transaction which makes the streaming upload fail
with this error:
upload failed: file size does not match (-2)

This test was tripped by the Storj backend and this patch fixes the

Before this change a server side copy did not preserve the modtime.
This used to work on nextcloud but at some point it started ignoring

Zoho has started returning the results from Range: requests with a 200
response code rather than the technically correct 206 error code.
Before this change this triggered workaround code to deal with Zoho
not obeying Range: requests properly.
This fix tests the returned header for a Content-Range: header and if
it exists assumes it is a valid reply to the Range: request despite
the status being 200.
This problem was spotted by the integration tests.
Before this fix, if the upload failed for some reason the yandex
backend would attempt to retry itself it which would fail immediately
with 400 Bad Request.
Normally we retry uploads at a higher level so they can be done with
new data and this patch does that.
See #7044
Before this change the Errors type in the union backend produced
errors which could not be Unwrapped to test their type.
This adds the (go1.20) Unwrap method to the Errors type which allows

It also adds unit tests for the Errors type and fixes a couple of
minor bugs thrown up in the process.

Implement a Partialuploads feature flag to mark backends for which
uploads are not atomic.
This is set for the following backends
- local
- ftp

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 using /path/to/file.rclonelink would not find the

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.

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.

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.
