This adds a bit of missed locking around the uploaded info to fix the
concurrent map write.
All the other accesses have locking - this one must have got missed.
pureftpd has a bug where it sends messages like this
```
150-Accepted data connection\r\n
Response code: File status okay; about to open data connection (150)
Response arg: Accepted data connection
150 32768.0 kbytes to download\r\n
150 0.014 seconds (measured here), 1665.27 Mbytes per second\r\n
```
The last `150` is treated as a new response - the previous `150` should have been `150-`.
This means that rclone sees the `150 0.014 seconds (measured here),
1665.27 Mbytes per second` as a reply to the next message and reports
it as an error.
This fix ignores that specific message when it is received in the
`Close` method. It dumps the FTP connection after as it is out of
sync.
See: #3984Fixes#3445
Before this change if rclone failed to close a file download for some
reason it would leak a concurrency token. When all the tokens were
leaked then rclone would lock up.
This fix returns the concurrency token regardless of the error status.
Before this change if rclone failed to upload a file for some reason
it would leak a concurrency token. When all the tokens were leaked
then rclone would lock up.
The fix returns the concurrency token regardless of the error state.
Before this change if rclone failed to make an FTP connection for some
reason it would leak a concurrency token. When all the tokens were
leaked then rclone would lock up.
The fix returns the concurrency token if creating the FTP connection
returns an error.
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/
This removes the unused functions run.writeRemoteRandomBytes() run.writeObjectRandomBytes() run.listPath() Directory.parentRemote() and Persistent.dumpRoot().
Before this change, when uploading multipart files, onedrive would
sometimes return an unexpected 416 error and rclone would abort the
transfer.
This is usually after a 500 error which caused rclone to do a retry.
This change checks the upload position on a 416 error and works how
much of the current chunk to skip, then retries (or skips) the current
chunk as appropriate.
If the position is before the current chunk or after the current chunk
then rclone will abort the transfer.
See: https://forum.rclone.org/t/fragment-overlap-error-with-encrypted-onedrive/14001Fixes#3131
This hides:
- "use_created_date"
- "use_shared_date"
- "size_as_quota"
from the configurator (rclone config) as they interfere with normal
operations and shouldn't be set in a backend config.
They can still be put in the config file by hand and will still work
as variables, etc.
This adds some more docs to "size_as_quota" also.
Fixes#3912
Before this change we used non multipart uploads for files of unknown
size (streaming and uploads in mount). This is slower and less
reliable and is not recommended by Google for files smaller than 5MB.
After this change we use multipart resumable uploads for all files of
unknown length. This will use an extra transaction so is less
efficient for files under the chunk size, however the natural
buffering in the operations.Rcat call specified by
`--streaming-upload-cutoff` will overcome this.
See: https://forum.rclone.org/t/upload-behaviour-and-speed-when-using-vfs-cache/9920/
This error started happening after updating golang/x/crypto which was
done as a side effect of:
3801b8109 vendor: update termbox-go to fix ncdu command on FreeBSD
This turned out to be a deliberate policy of making
ssh.ParsePrivateKeyWithPassphrase fail if the passphrase was empty.
See: https://go-review.googlesource.com/c/crypto/+/207599
This fix calls ssh.ParsePrivateKey if the passphrase is empty and
ssh.ParsePrivateKeyWithPassphrase otherwise which fixes the problem.
If the --drive-stop-on-upload-limit flag is in effect this checks the
error string from Google Drive to see if it is the error you get when
you've breached your 750GB a day limit.
If so then it turns this error into a Fatal error which should stop
the sync.
Fixes#3857
In listings if the ID `appDataFolder` is used to list a directory the
parents of the items returned have the actual ID instead the alias
`appDataFolder`. This confused the ListR routine into ignoring all
these items.
This change makes the listing routine accept all parent IDs returned
if there was only one ID in the query. This fixes the `appDataFolder`
problem. This means we are relying on Google Drive to only return the
items we asked for which is probably OK.
Fixes#3851
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.
Before this patch we were failing to URL decode the NextMarker when
url encoding was used for the listing.
The result of this was duplicated listings entries for directories
with >1000 entries where the NextMarker was a file containing a space.
Before this change we used the same (relatively low limits) for server
side copy as we did for multipart uploads. It doesn't make sense to
use the same limits since no data is being downloaded or uploaded for
a server side copy.
This change introduces a new parameter --s3-copy-cutoff to control
when the switch from single to multipart server size copy happens and
defaults it to the maximum 5GB.
This makes server side copies much more efficient.
It also fixes the erroneous error when trying to set the modification
time of a file bigger than 5GB.
See #3778
Before this change multipart copies were giving the error
Range specified is not valid for source object of size
This was due to an off by one error in the range source introduced in
7b1274e29a "s3: support for multipart copy"
Before this change rclone used "Authorization: BEARER token". However
according the the RFC this should be "Bearer"
https://tools.ietf.org/html/rfc6750#section-2.1
This changes it to "Authorization: Bearer token"
Fixes#3751 and interop with Salesforce Webdav server
When using nextcloud, before this change we only uploaded one of SHA1
or MD5 checksum in the OC-Checksum header with preference to SHA1 if
both were set.
This makes the MD5 checksums read as empty string which makes syncing
with checksums less useful than they should be as all the MD5
checksums are blank.
This change makes it so that we only upload the SHA1 to nextcloud.
The behaviour of owncloud is unchanged as owncloud uses the checksum
as an upload integrity check only and calculates its own checksums.
See: https://forum.rclone.org/t/how-to-specify-hash-method-to-checksum/13055
This also corrects the symlink detection logic to only check symlink
files. Previous to this it was checking all directories too which was
making it do more stat calls than was necessary.
Before this change we forgot to URL decode the X-Object-Manifest in a dynamic large object.
This problem was introduced by 2fe8285f89 "swift: reserve
segments of dynamic large object when delete objects in container what
was enabled versioning."
For few commands, RClone counts a error multiple times. This was fixed by
creating a new error type which keeps a flag to remember if the error has
already been counted or not. The CountError function now wraps the original
error eith the above new error type and returns it.
Before this change rclone used the team_drive ID as the root if set
even if the root_folder_id was set too.
This change uses the root_folder_id in preference over the team_drive
which restores the functionality.
This problem was introduced by ba7c2ac443Fixes#3742
We attempt to find the ID of the root folder by doing a GET on the
folder ID "root". With scope "drive.files" this fails with a 404
message.
After this change if we get the 404 message, we just carry on using
"root" as the root folder ID and we cache that for future lookups.
This means that changenotify messages will not work correctly in the
root folder but otherwise has minor consequences.
See: https://forum.rclone.org/t/fresh-raspberry-pi-build-google-drive-404-error-failed-to-ls-googleapi-error-404-file-not-found/12791
Before this change rclone would allow the user to stream (eg with
rclone mount, rclone rcat or uploading google photos or docs) 5TB
files. This meant that rclone allocated 4 * 525 MB buffers per
transfer which is way too much memory by default.
This change makes rclone use the configured chunk size for streamed
uploads. This is 5MB by default which means that rclone can stream
upload files up to 48GB by default staying below the 10,000 chunks
limit.
This can be increased with --s3-chunk-size if necessary.
If rclone detects that a file is being streamed to s3 it will make a
single NOTICE level log stating the limitation.
This fixes the enormous memory usage.
Fixes#3568
See: https://forum.rclone.org/t/how-much-memory-does-rclone-need/12743
Before this fix we neglected to add the shared drive ID to the request
when asking for an initial change notify token and this caused a lot
more results to be returned than was necessary.
When we changed recursive lists to use --fast-list by default this
broke listing with --drive-shared-with-me from the root.
This turned out to be an unwarranted assumption in the ListR code that
all items would have a parent folder that we had searched for - this
isn't true for shared with me items.
This was fixed when using --drive-shared-with-me to give items that
didn't have any parents a synthetic parent.
Fixes#3639
Before this change we used the id "root" as an alias for the root drive ID.
However this causes problems when we receive IDs back from drive which
are not in this format and have been expanded to their canonical ID.
This change looks up the ID "root" and stores it in the
"drive_folder_id" parameter in the config file.
This helps with
- Notifying changes at the root
- Files shared with me at the root
See #3639
Before this change when rclone was compiled with go1.13 it used HTTP/2
to contact drive by default.
This causes lockups and INTERNAL_ERRORs from the HTTP/2 code.
This is a workaround disabling the HTTP/2 code on an option.
It can be re-enabled with `--drive-disable-http2=false`
See #3631
Before this change we silently skipped uploads to dropbox of
disallowed file names. However this then caused "corrupted on
transfer" errors because the sizes were wrong.
After this change we return an no retry error which will mean that the
sync fails (as it should - not all files were uploaded) but no
unecessary retries happened.
This works around a bug in Ceph which doesn't encode CommonPrefixes
when using URL encoded directory listings.
See: https://tracker.ceph.com/issues/41870
changes:
- chunker: remove GetTier and SetTier
- remove wdmrcompat metaformat
- remove fastopen strategy
- make hash_type option non-advanced
- adverise hash support when possible
- add metadata field "ver", run strict checks
- describe internal behavior in comments

note:
wdmrcompat used to write file name in the metadata, so maximum metadata
size was 1K; removing it allows to cap size by 200 bytes now.
Note: chunker implements many irrelevant methods (UserInfo, Disconnect etc),
but they are required by TestIntegration/FsCheckWrap and cannot be removed.
Dropped API methods: MergeDirs DirCacheFlush PublicLink UserInfo Disconnect OpenWriterAt
Meta formats:
- renamed old simplejson format to wdmrcompat.
- new simplejson format supports hash sums and verification of chunk size/count.

- Read the storage class for each object
- Implement SetTier/GetTier
- Check the storage class on the **object** before using SetModTime
This updates the fix in 1a2fb52 so that SetModTime works when you are
using objects which have been migrated to GLACIER but you aren't using
GLACIER as a storage class.
Fixes#3522
Before this change we used PATCH on the object to update the metadata.
Apparently this requires the "full_control" scope which Google were
unhappy with in their oauth review.
This changes it to update the metadata by copying the object ontop of
itself (which is the way s3 works). This can be done with normal
permissions.
This fixes a crash on the google photos backend when an error is
returned from the rest.Call function.
This turned out to be a mis-understanding of the rest docs so
- improved rest.Call docs
- fixed mis-understanding in google photos backend
- fixed similar mis-understading in onedrive backend
- change the interface of listBuckets() removing dir parameter and adding context
- add makeBucket() and use in place of Mkdir("")
- this fixes some corner cases in Copy/Update
- mark all the listed buckets OK in ListR
Thanks to @yparitcher for the review.
Before this change, if the caller didn't provide a hint, we would
calculate all hashes for reads and writes.
The new whirlpool hash is particularly expensive and that has become noticeable.
Now we don't calculate any hashes on upload or download unless hints are provided.
This means that some operations may run slower and these will need to be discovered!
It does not affect anything calling operations.Copy which already puts
the corrects hints in.
When using the VFS with swift and --swift-no-chunk, PutStream was
returning objects with size -1 which was causing corrupted transfer
messages.
This was fixed by counting the bytes transferred in a streamed file
and updating the metadata with that.
This was factored from fstest as we were including the testing
enviroment into the main binary because of it.
This was causing opening the browser to fail because of 8243ff8bc8.
In 53a1a0e3ef we started returning non nil from NewObject when
an object isn't found. This breaks the integration tests and the API
expected of a backend.
This fixes it.
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.
Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.
For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.
Configuration time option to disable the above for if using Dropbox (does not
allow setting mtime on copy) or Amazon Drive (neither on upload nor on copy).
Before this change rclone was sending a MimeType in the requests for
server side Move and Copy.
The conjecture is that if you attempt to set the MimeType to something
different in a Copy then Google Drive has to do an actual copy of the
file data. This takes a very long time (since it is large) and fails
after a 90s timeout.
After the change we no longer set the MimeType in Move or Copy and the
copies happen instantly and correctly.
Many thanks to @darthShadow for discovering that this was causing the
problem.

This bug was introduced as part of adding context to the backends and
slipped through the net because the About call did not have an
interface assertion in the sftp backend.
I checked there were no other missing interface assertions on all the
optional methods on all the backends.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
Before this change rclone attempted to set the "updated" field in
uploaded objects to the modification time.
However when this modification time was before 1970, google drive
would return the rather cryptic error:
googleapi: Error 400: Invalid value for UnsignedLong: -42000, invalid
However API docs: https://cloud.google.com/storage/docs/json_api/v1/objects#resource
state the "updated" field is read only and tests confirm that. Even
though the field is read only, it looks like Google parses it.
This change therefore removes the attempt to set the "updated" field
(which was doing nothing anyway) and fixes the problem uploading pre
1970 files.
See #3196 and https://forum.rclone.org/t/invalid-value-for-unsignedlong-file-missing-date-modified/3466
In #2728 and 55b9a4e we decided to allow server side operations
between google drives with different configurations.
This works in some cases (eg between teamdrives) but does not work in
the general case, and this caused breakage in quite a number of
people's workflows.
This change makes the feature conditional on the
--drive-server-side-across-configs flag which defaults to off.
See: https://forum.rclone.org/t/gdrive-to-gdrive-error-404-file-not-found/9621/10Fixes#3119
Under Linux, rclone attempts to preallocate files for efficiency.
Before this change, pre-allocation would fail on ZFS with the error
Failed to pre-allocate: operation not supported
After this change rclone tries a different flag combination for ZFS
then disables pre-allocate if that doesn't work.
Fixes#3066
Before this change rclone would fail with
Failed to set modification time: InvalidObjectState: Operation is not valid for the source object's storage class
when attempting to set the modification time of an object in GLACIER.
After this change rclone will re-upload the object as part of a sync if it needs to change the modification time.
See: https://forum.rclone.org/t/suspected-bug-in-s3-or-compatible-sync-logic-to-glacier/10187
Before this change, rclone would return an error from the listing if
there was an unreadable directory, or if there was a problem stat-ing
a directory entry. This was frustrating because the command
completely aborts at that point when there is work it could do.
After this change rclone lists the directories and reports ERRORs for
unreadable directories or problems stat-ing files, but does return an
error from the listing. It does set the error flag which means the
command will fail (and objects won't be deleted with `rclone sync`).
This brings rclone's behaviour exactly in to line with rsync's
behaviour. It does as much as possible, but doesn't let the errors
pass silently.
Fixes#3179
Before this change we calculated all possible hashes for the file when
the `Hashes` method was called.
After we only calculate the Hash requested.
Almost all uses of `Hash` just need one checksum. This will slow down
`rclone lsjson` with the `--hash` flag. Perhaps lsjson should have a
`--hash-type` flag.
However it will speed up sync/copy/move/check/md5sum/sha1sum etc.
Before it took 12.4 seconds to md5sum a 1GB file, after it takes 3.1
seconds which is the same time the md5sum utility takes.
This fixes rclone returning `listing failed: strconv.ParseInt` errors
when listing files which have a malformed `src_last_modified_millis`.
This is uploaded by the client so care is needed in interpreting it as
it can be malformed.
Fixes#3065
In as many methods as possible we attempt to obey the Retry-After
header where it is provided.
This means that when objects are being requested from OVH cold storage
rclone will sleep the correct amount of time before retrying.
If the sleeps are short it does them immediately, if long then it
returns an ErrorRetryAfter which will cause the outer retry to sleep
before retrying.
Fixes#3041
This implements the Expiry interface so token expiry works properly

Some WebDAV servers return an empty Available and Used which parses as 0.
This caused About to return the Total as 0 which can confused mounted
file systems.
After this change we ignore the result if Available and Used are both 0.
See: https://forum.rclone.org/t/windows-mounted-webdav-drive-has-no-free-space/8938
Before this change a race condition existed in mkdir
- the directory was attempted to be created
- the parent didn't exist so it failed
- the parent was created
- the directory was created again
The last step failed as the directory was created in a different thread.
This was fixed by checking the error messages of MKCOL for both
directory creations, rather than only the first.
Before this change a range request on a 0 length file would fail
$ rclone cat --head 128 drive:test/emptyfile
ERROR : open file failed: googleapi: Error 416: Request range not satisfiable, requestedRangeNotSatisfiable
To fix this we remove Range: headers on requests for zero length files.
This introduces a new config variable bucket_policy_only. If this is
set then rclone:
- ignores ACLs set on buckets
- ignores ACLs set on objects
- creates buckets with Bucket Policy Only set
Fall back to default application credentials when all other credentials sources fail
This change allows users with default application credentials
configured (notably when running on google compute instances) to
dispense with explicitly configuring google cloud storage credentials
in rclone's own configuration.
This enables MD5 checksum calculation and publication when uploading file above the "Cutoff" limit.
It was explictely ignored in case of multi-block (a.k.a. multipart) uploads to Azure Blob Storage.
Make the pacer package more flexible by extracting the pace calculation
functions into a separate interface. This also allows to move features
that require the fs package like logging and custom errors into the fs
package.
Also add a RetryAfterError sentinel error that can be used to signal a
desired retry time to the Calculator.
