- fix test case FsNewObjectCaseInsensitive (PR #4830)
- continue PR #4917, add comments in metadata detection code
- add warning about metadata detection in user documentation
- change metadata size limits, make room for future development
- hide critical chunker parameters from command line
Before this patch chunker required that there is at least one
data chunk to start checking for a composite object.
Now if chunker finds at least one potential temporary or control
chunk, it marks found files as a suspected composite object.
When later rclone tries a concrete operation on the object,
it performs postponed metadata read and decides: is this a native
composite object, incompatible metadata or just garbage.
This includes an HDFS docker image to use with the integration tests.

The current authentication scheme works without creating
a public download endpoint for a private bucket as in the B2 official blog.
On the contrary, if the existing authorization header gets duplicated
in the Cloudflare Workers script, one might receive 401 Unauthorized errors.
Before this change the webdav backend didn't truncate Range requests
to the size of the object. Most webdav providers are OK with this (it
is RFC compliant), but it causes 4shared to return 500 internal error.
Because Range requests are used in mounting, this meant that mounting
didn't work for 4shared.
This change truncates the Range request to the size of the object.
See: https://forum.rclone.org/t/cant-copy-use-files-on-webdav-mount-4shared-that-have-foreign-characters/21334/
Before this change, attempting to update an archive tier blob failed
with a 409 error message:
409 This operation is not permitted on an archived blob.
This change detects if we are overwriting a blob and either generates
the error (if `--azureblob-archive-tier-delete` is not set):
can't update archive tier blob without --azureblob-archive-tier-delete
Or deletes the blob first before uploading it again (if
`--azureblob-archive-tier-delete` is set).
Fixes#4819
Before this change if you attempted to list a remote set up with a SAS
URL outside its container then it would crash the Azure SDK.
A check is done to make sure the root is inside the container when
starting the backend which is usually enough, but when two SAS URL
based remotes are mounted in a union, the union backend attempts to
read paths outside the named container. This was causing a mysterious
crash in the Azure SDK.
This fixes the problem by checking to see if the container in the
listing is the one in the SAS URL before listing the directory and
returning directory not found if it isn't.
Before this change when NewObject was called the b2 backend would list
the directory that the object was in in order to find it.
Unfortunately list calls are Class C transactions and cost more.
This patch switches to using HEAD requests instead. These are Class B
transactions. It is then necessary to parse the headers from response
back into the data that we get from the listing. However B2 returns
exactly the same data, just in a different form.
Rclone will use the old directory listing method when looking for
files with versions as these can't be found via a HEAD request.
This change will particularly benefit --files-from, rclone serve
restic but most operations will see some benefit.
Starting September 30th, 2021, the Dropbox OAuth flow will no longer
return long-lived access tokens. It will instead return short-lived
access tokens, and optionally return refresh tokens.
This patch adds the token_access_type=offline parameter which causes
dropbox to return short lived tokens now.
Before this change rclone would upload the whole of multipart files
before receiving a message from dropbox that the path was too long.
This change hard codes the 255 rune limit and checks that before
uploading any files.
Fixes#4805
Before this change, rclone would retry files with filenames that were
too long again and again.
This changed recognises the malformed_path error that is returned and
marks it not to be retried which stops unnecessary retrying of the file.
See #4805
Before this change rclone was using the copy endpoint to copy large objects.
This can fail for large objects with this error:
Error 413: Copy spanning locations and/or storage classes could
not complete within 30 seconds. Please use the Rewrite method
This change makes Copy use the Rewrite method as suggested by the
error message which should be good for any size of copy.
Yandex appears to ignore mime types set as part of the PUT request or
as part of a PATCH request.
The docs make no mention of being able to set a mime type, so set
WriteMimeType=false indicating the backend can't set mime types on
uploaded files.
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
Before this change, small objects uploaded with SSE-AWS/SSE-C would
not have MD5 sums.
This change adds metadata for these objects in the same way that the
metadata is stored for multipart uploaded objects.
See: #1824#2827
If rclone is configured for server side encryption - either aws:kms or
sse-c (but not sse-s3) then don't treat the ETags returned on objects
as MD5 hashes.
This fixes being able to upload small files.
Fixes#1824
This shouldn't be read as encouraging the use of math/rand instead of
crypto/rand in security sensitive contexts, rather as a safer default
if that does happen by accident.
For some reason the API started returning some integers as strings in
JSON. This is probably OK in Javascript but it upsets Go.
This is easily fixed with the `json:"name,size"` struct tag.
Before this change a circular symlink would cause rclone to error out from the listings.
After this change rclone will skip a circular symlink and carry on the listing,
producing an error at the end.
Fixes#4743
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
It seems that when doing chunked uploads to onedrive, if the chunks
take more than 3 minutes or so to upload then they may timeout with
error 504 Gateway Timeout.
This change produces an error (just once) suggesting lowering
`--onedrive-chunk-size` or decreasing `--transfers`.
This is easy to replicate with:
rclone copy -Pvv --bwlimit 0.05M 20M onedrive:20M
See: https://forum.rclone.org/t/default-onedrive-chunk-size-does-not-work/20010/
Minor wording change to help for explicit and implicit FTPS flags. More consistent between flags. Add 's' to request because only one 'client' mentioned.
As reported in
https://github.com/rclone/rclone/issues/4660#issuecomment-705502792
After switching to a password callback function, if the ssh connection
aborts and needs to be reconnected then the user is-reprompted for their
password. Instead we now remember the password they entered and just give
that back. We do lose the ability for them to correct mistakes, but that's
the situation from before switching to callbacks. We keep the benefits
of not asking for passwords until the SSH connection succeeds (right
known_hosts entry, for example).
This required a small refactor of how `f := &Fs{}` was built, so we can
store the saved password in the Fs object
Before this change rclone returned the size from the Stat call of the
link. On Windows this reads as 0 always, however on unix it reads as
the length of the text in the link. This caused errors like this when
syncing:
Failed to copy: corrupted on transfer: sizes differ 0 vs 13
This change causes Windows platforms to read the link and use that as
the size of the link instead of 0 which fixes the problem.
Based on Issue 4087
https://github.com/rclone/rclone/issues/4087
Current behaviour is insecure. If the user specifies this value then we
switch to validating the server hostkey and so can detect server changes
or MITM-type attacks.
This allows files to be copied by ID from google drive. These can be
copied to any rclone remote and if the remote is a google drive then
server side copy will be attempted.
Fixes#3625
This type of error is unlikely to be an error that can be resolved by a retry,
and is triggered in #2296 by files with a timestamp before the unix epoch.
The maximum value for the --s3--copy-cutoff should be 5GiB as tested
with AWS S3.
However b2 have implemented this as 5GB rather than 5GiB so having the
default at 5 GiB makes the b2s3 server side copy of a large file by
default.
This patch sets the default to 4768 MiB which is slightly less than
5GB.
This should have very little effect on anything.
If in future rclone can lower this limit more if Copy can multithread.
See: https://forum.rclone.org/t/copying-files-within-a-b2-bucket/16680/76
Before this change the s3 multipart server side copy was not
preserving the metadata of the object. This was most noticeable
because the modtime was not preserved.
This change fetches the metadata from the object before starting the
copy and overwrites it if requires.
It will also mean any other metadata is preserved.
See: https://forum.rclone.org/t/copying-files-within-a-b2-bucket/16680/70
Before this change, when the above backends created a new backend they
didn't put it into the backend cache.
This meant that rc commands acting on those backends did not work.
This was fixed by making sure the backends use the backend cache.
See: https://forum.rclone.org/t/rclone-rc-backend-command-not-working-as-expected/18834
Before this change writing with the all policy deadlocked while
uploading.
This change fixes the problem by fixing the multi reader, closing the
pipes at the correct time with the correct error. This is factored
into a new function as it was used twice.
This patch also adds a new test which tests the all policies.
Before this fix we were reading the hash from the upload using the
string "ETag", however the go runtime normalises the tag into "Etag"
so we were in fact always reading an empty string.
This bug was introduced in
aeea4430d5 swift: efficiency: slim Object and reduce requests on upload
It was spotted by the integration tests.
The fix was just to use the canonical form "Etag" instead of "ETag".
In this commit
a2afa9aadd fs: Add directory to optional Purge interface
We failed to encrypt the directory name so the Purge failed.
This was spotted by the integration tests.
In this commit:
cbf3d43561 drive: fix missing items when listing using --fast-list / ListR
We introduced a bug where under specific circumstances it could cause
a "panic: send on closed channel".
This was caused by:
- rclone engaging the workaround from the commit above
- one of the listing routines returning an error
- this caused the `in` channel to be closed to stop the readers
- however the workaround was recycling stuff into the `in` channel at the time
- hence the panic on closed channel
This fix factors out the sending to the `in` channel into `sendJob`
and calls this both from the master go routine and the list
runners. `sendJob` detects the `in` channel being closed properly and
also deals correctly with contention on the `in` channel.
Fixes#4511
When using `rclone authorize` the hostname doesn't get set in the
config file.
This commit allows it to be set in the configurator and gives the user
a hint that it needs setting.
This reverts part of
151f03378f s3: fix upload of single files into buckets without create permission
This erroneously assumed that a HEAD request on a non existent object
would return "NotFound" if the bucket was found. In fact it returns
"NotFound" when the bucket isn't found also.
This will break the fix for #4297 - however that can be made to work
using the new --s3-assume-bucket-exists flag
Before this change, rclone was looking for the file without the
extension to see if it existed which meant that it never did.
This change checks the destination file exists firsts, before removing
the extension.
Google drive appears to no longer be copying the modification time of
google docs.
Setting the mod time immediately after the copy doesn't work either,
so this patch copies the object, waits for 1 second and then sets the
modtime.
Fixes#4517
This was only working for files in the root directory and wasn't
looking at the encoding.
This is fixed to use NewObject which takes both things into account
and it makes the share by ID instead of by path.
This problem was spotted by the integration tests.
Before this change we errored out if one upstream errored in Purge or
About.
This change checks for fs.ErrorDirNotFound and skips that backend in
this case.
1. adds SharedOptions data structure to oauthutil
2. adds config.ConfigToken option to oauthutil.SharedOptions
3. updates the backends that have oauth functionality
Fixes#2849
After uploading a multipart object, rclone deletes any unused parts.
Probably as part of the listing unification, the detection of the
parts beloning to the current upload was failing and calling Update
was deleting the parts for the current object.
This change fixes the detection and deletes all the old parts but none
of the new ones now.
Fixes#4075
Previous to this change rclone cached the looked up root_folder_id in
the root_folder_id config variable.
This has caused a lot of confusion and a few attempts at workarounds
and ultimately was a mistake.
This reverts rclone attempting to cache anything in root_folder_id and
returns that variable to be entirely user modified.
It gives a little hint in the debug that rclone could be sped up
slightly by setting it, but it is up to the user to think about
whether that would be OK or not.
Google drive root '': root_folder_id = "XXX" - save this in the config to speed up startup
It does not change root_folder_id itself, leaving this to the user.
See: https://forum.rclone.org/t/rclone-gdrive-no-longer-returning-anything/17215
- add a directory to the optional Purge interface
- fix up all the backends
- add an additional integration test to test for the feature
- use the new feature in operations.Purge
Many of the backends had been prepared in advance for this so the
change was trivial for them.
If this option is enabled, rclone will not set modtime of uploaded files and
the backend will return ModTimeNotSupported as its Precision.
Normally rclone updates modification time of files after they are done
uploading. This can cause permissions issues on Linux platforms when
rclone is copying to a CIFS mount where the user rclone is
running as does not own the file uploaded. If this option is enabled,
rclone will no longer update the modtime after copying a file.
See: https://forum.rclone.org/t/chtimes-error-on-local-mounted-copy/17784
This implements `rclone cleanup` to remove multipart uploads over 24
hours old. It also implements the backend command
`list-multipart-uploads` to see which ones are available and `cleanup`
to delete them with a configurable expiry interval.
See #4302
Before this fix, if an object had ID set and download_url was in use,
downloading the object would give this error:
failed to open for download: bucket example_bucket does not have file: /b2api/v1/b2_download_file_by_id (404 not_found)
After this fix we only download by ID if download_url is not set
See: https://forum.rclone.org/t/correct-format-for-rclone-b2-download-url-variable/15498
When we run MKCOL on 4shared on a directory that already exists, this
returns a 409/Conflict error. However this error code usually means
that the intermediate collections need creating.
The actual error code to return when trying to create a directory that
already exists isn't specified in the RFC, only that an error MUST be
returned and there are already 3 statuses checked in the code.
However using 409 makes rclone's usual strategy for making directories
fail and return the 409 error.
This patch tries the MKCOL and if it returns an unrecognised error
code, then calls PROPFIND on the directory to discover whether the
directory really exists or not.
This should also cover other WebDAV servers returning other error
messages we haven't accounted for in the code yet.
Before this change the cache backend contained its own routines for
mounting testing on that mount.
These tests are never run on the CI and cause a maintenance burden.
This commit removes the tests.
Previous to this fix if Region was not set and Endpoint was not set
then we set the endpoint to "https://s3.amazonaws.com/".
This is unecessary because if the Region alone isn't set then we set
it to "us-east-1" which has the same endpoint.
Having the endpoint set breaks the bucket region auto detection with
the error "Failed to update region for bucket: can't set region to
"xxx" as endpoint is set".
This fix removes that check.
At some point Purge stopped deleting directory markers. We don't have
an integration test for this so it went unnoticed.
This patch fixes the problem but doesn't introduce an integration test
as we don't have a framework for making directory markers yet.
Before this change, large objects which had had their contents deleted
would return "Object not found" and break the listing.
This change makes these objects appear as 0 sized entities so they can
be listed and deleted.
Pcloud appears to have opened up a new region and they are returning
the hostname in the oauth callback, thus
GET /?code=XXX&locationid=1&hostname=api.pcloud.com&state=XXX HTTP/1.1
GET /?code=XXX&locationid=2&hostname=eapi.pcloud.com&state=XXX HTTP/1.1
This isn't documented yet, however pCloud have confirmed that this is
the correct interpretation.
Rclone now reads the "hostname" parameter in the oauth callback and
stores it in the config file. It uses it for all subequent API calls.
Previous to this a dangling shortcut would error the directory
listing.
This patch makes dangling shortcuts appear as 0 sized objects in the
directory listing so they can be deleted. These objects can't be read
though.
For some objects the onedrive backend has been doing a server side
copy and a delete when a server side move would have worked OK.
This was caused by not detecting the home drive correctly (when it was
an empty string) and assuming that these transfers were cross drive.
This is fixed by comparing canonicalizing drive IDs before comparing them.
Currently credentials are required to download a public bucket file
which is not really necessary and makes automated usage more complex.
Add a new option "anonymous" which when enabled configures the gcs
backend to use an anonymous HTTP client. This of course only works
for read access and trying to write will lead to errors like that:
"googleapi: Error 401: Anonymous caller does not not have
storage.objects.create access to the Google Cloud Storage object.",
as expected. By default the anonymous access option is disabled so that
the GCS Application Default Credentials are still used by default as
before and an error is given if they can't be found.
Before this change rclone used the relative path from the current
working directory.
It appears that WS FTP doesn't like this and the openssh sftp tool
also uses absolute paths which is a good reason for switching to
absolute paths.
This change reads the current working directory at startup and bases
all file requests from there.
See: https://forum.rclone.org/t/sftp-ssh-fx-failure-directory-not-found/17436
Before this change the --local-no-updated flag would not error if the
files changed in size during the transfer. The file could still be
read beyond the size advertised though which caused problems with
certain backends.
After this change we attempt to provide a consistent view of the file
once it has been opened.
Once the file has had stat() called on it for the first time we
- Only transfer the size that stat gave
- Only checksum the size that stat gave
- Don't update the stat info for the file
This means that files that are extending can be transferred - rclone
will transfer the length it saw the first time it listed the file.
See: https://forum.rclone.org/t/transport-connection-broken/16494/21
In this commit
5c5ad6220 drive: fix --drive-impersonate with cached root_folder_id
We disabled the use of root_folder_id with --drive-impersonate to fix
a problem with a cached root_folder_id giving the wrong results.
This, alas, broke one users setup with a root_folder_id of
appDataFolder. Since this is identifiable and definitely couldn't have
been cached, we can safely skip this check in this case.
See: https://forum.rclone.org/t/rclone-gdrive-no-longer-returning-anything/17215/10
Before this change there was lots of duplicated code in all the
dircache using backends to support DirMove.
This change factors this code into the dircache library.
Dircache was changed to:
- Remove special cases for the root directory
- Remove Fatal errors
- Call FindRoot on behalf of the user wherever possible
- Bring up to modern Go standards
Backends were changed to:
- Remove calls to FindRoot
- Change calls to FindRootAndPath to FindPath
- Don't make special cases for the root
This fixes several corner cases, for example removing a non existent
directory if FindRoot hasn't been called.
Before this fix rclone would continually try to delete non empty
segment containers which made deleting lots of files very slow.
This fix makes rclone just try the delete once and then carry on which
was the original intent of the code before the retry logic got put in.
Before this change if the server sent us xml like this
```
<D:propstat>
<D:prop>
<g0:quota-available-bytes/>
<g0:quota-used-bytes/>
</D:prop>
<D:status>HTTP/1.1 404 Not Found</D:status>
</D:propstat>
```
Rclone would read the empty XML items as containing 0
After this fix we make sure that we have a value before using it.
Before this fix rclone v1.51 and 1.52 would incorrectly use the cached
root_folder_id when the --drive-impersonate flag was in use. This
meant that rclone could be looking up the wrong directory ID with
unpredictable results - usually all files apparently being missing.
This fix makes rclone look up the root_folder_id always when using
--drive-impersonate. It does this by clearing the root_folder_id and
making a NOTICE message that it is ignoring the cached value.
It also stops rclone caching the root_folder_id when using
--drive-impersonate.
See: https://forum.rclone.org/t/rclone-gdrive-no-longer-returning-anything/17215
Adding the expires parameter gives settings_error/not_authorized/.. errors.
The expires setting isn't in the documentation so this commit removes
it for now.
For SSH authentication, `key_pem` should both override `key_file`
and not require other SSH authentication methods to be set.
Prior to this fix, rclone would attempt to use an ssh-agent
when `key_pem` was the only SSH authentication method set.
Fixes#4240
