Windows webdav does an OPTIONS request on the root even when given a
path and if we return 404 here then Windows refuses to use the path.
This patch allows OPTIONS requests only on the root to fix this.
This affects all the HTTP servers.
This change adds the --direct-io flag to the mount. This means the
page cache is completely bypassed for reads and writes. No read-ahead
takes place. Shared mmap is disabled.
This is useful to accurately read files which may change length
frequently on the source.
Before this change, if a file shrunk in size on the remote then rclone
could get into an loop trying to download the file forever.
The symptom was repeating errors like this:
vfs cache: restart download failed: failed to start downloader: failed to open downloader: vfs reader: failed to open source file: invalid seek position
The fix was to check that file size in various places and makes sure
that we weren't trying to download too much data.
This was a problems with backends (like s3) which update the size of
the object on Open to the actual size of the object.
Before this change trying to server side copy an object from a my
drive to a shared drive using --metadata caused this error:
Sharing restrictions cannot be set on a shared drive item., teamDrivesSharingRestrictionNotAllowed
This was because we were setting the "writers-can-share" metadata
which isn't allowed on shared drives
Before this change operations.SetDirModTime could return the error
"optional feature not implemented" when attempting to set modification
times on crypted sftp backends.
This was because crypt wraps the directories using fs.DirWrapper but
these return fs.ErrorNotImplemented for the SetModTime method.
The fix is to recognise that error and fall back to using the
DirSetModTime method on the backend which does work.
Fixes#7673
Some backends (like s3, swift, gcs, azureblob) don't have directories
(this can be overridden on some using the directory markers feature).
It therefore makes no sense to sync directory times from them as they
will all be a value made up by rclone (--default-time)
We use the feature flag CanHaveEmptyDirectories to mark backends
without real directory support and disable the directory modification
time syncing on those.
In this commit (2014 for v1.02) Purge was implemented for the local
backend:
1527e64ee7 local: Implement Purger interface
This appeared to be implemented just to make a Purge and doesn't
appear to do anything useful.
It is in fact significatly worse than the rclone fallback purge since
it doesn't operate in parallel or update stats.
This patch removes the Purge routine for a consequent speed up and
showing of stats.
See: https://forum.rclone.org/t/progress-flag-for-rclone-purge/44416
Directory mod times are synced by default if the backend is capable
and directory metadata is synced if the --metadata flag is provided
and the backend is capable.
This updates the bisync golden tests also which were affected by
--dry-run setting of directory modtimes.
Fixes#6685
Before this change this would give errors like this
failed to set metadata on directory: failed to set birth (creation) time: Access is denied.
This was caused by opening the directory in the wrong mode.
A consequence of this is that fs.Directory returned by the local
backend will now have a correct size in (rather than -1). Some tests
depended on this and have been fixed by this commit too.
This involved adding the Fs() method to DirEntry as it is needed in
the metadata mapper.
Unspecialised fs.Dir objects will return a new fs.Unknown from their
Fs() methods as they are not specific to any given Fs.
Before this fix rclone would crash with
panic: encoding alphabet includes duplicate symbols
When compiled with go1.22. This was fixed upstream in
https://github.com/t3rm1n4l/go-mega/issues/48
And this just pulls in the fix.
Fixes#7639
GCS gives NotImplemented errors for multi-part server side copies. The
threshold for these is currently set just below 5G so any files bigger
than 5G that rclone attempts to server side copy will fail.
This patch works around the problem by adding a quirk for GCS raising
--s3-copy-cutoff to the maximum. This means that rclone will never use
multi-part copies for files in GCS. This includes files bigger than
5GB which (according to AWS documentation) must be copied with
multi-part copy. However this seems to work with GCS.

Before this change it wasn't possible to see where transfers were
going from and to in core/stats and core/transferred.
When use in rclone mount in particular this made interpreting the
stats very hard.
It was reported that rclone copy occasionally uploaded corrupted data
to azure blob.
This turned out to be a race condition updating the block count which
caused blocks to be duplicated.
This bug was introduced in this commit in v1.64.0 and will be fixed in v1.65.2
0427177857 azureblob: implement OpenChunkWriter and multi-thread uploads #7056
This race only seems to happen if `--checksum` is used but can happen otherwise.
Unfortunately Azure blob does not check the MD5 that we send them so
despite sending incorrect data this corruption is not detected. The
corruption is detected when rclone tries to download the file, so
attempting to copy the files back to local disk will result in errors
such as:
ERROR : file.pokosuf5.partial: corrupted on transfer: md5 hash differ "XXX" vs "YYY"
This adds a check to test the blocklist we upload is as we expected
which would have caught the problem had it been in place earlier.
Before this change StatsInfo.ResetCounters() and stopAverageLoop()
(when called from time.AfterFunc) could race on StatsInfo.average.
This was because the deferred stopAverageLoop accessed
StatsInfo.average without locking.
For some reason this only ever happened on macOS. This caused the CI
to fail on macOS thus causing the macOS builds not to appear.
This commit fixes the problem with a bit of extra locking.
It also renames all StatsInfo methods that should be called without
the lock to start with an initial underscore as this is the convention
we use elsewhere.
Fixes#7567
