Help people handle an issue which might be difficult to understand
otherwise.
If you have recursive shortcuts (pointing to a parent folder) in a
google drive, rclone is doing infinite recursion, never ending and
filling the disk. Even if you ask not to get shortcuts content.
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.
Before this change, List would return incorrect directory paths (relative to the
wrong root) if the Fs root pointed to a subdirectory. For example, listing dir
"a/b/c/d" of remote :memory: would work correctly, but listing dir "c/d" of
remote :memory:a/b would not, and would result in "Entry doesn't belong in
directory %q (contains subdir)" errors.
This change fixes the issue and adds a test to detect any other backends that
might have the same issue.
Before this change, the Memory backend had the potential to deadlock under
certain conditions, if the ListR callback required locking the b.mu mutex. This
was the case with operations.Purge, because Memory has no Purge method, and the
fallback option does:
err = DeleteFiles(ctx, listToChan(ctx, f, dir))
which potentially starts removing objects before the listing has completed.
This change fixes the issue by batching all the entries before calling the
callback on them.
This change officially adds bisync to the nightly integration tests for all
backends.
This will be part of giving us the confidence to take bisync out of beta.
A number of fixes have been added to account for features which can differ on
different backends -- for example, hash types / modtime support, empty
directories, unicode normalization, and unimportant differences in log output.
We will likely find that more of these are needed once we start running these
with the full set of remotes.
Additionally, bisync's extremely sensitive tests revealed a few bugs in other
backends that weren't previously covered by other tests. Fixes for those issues
have been submitted on the following separate PRs (and bisync test failures will
be expected until they are merged):
- #7670 memory: fix deadlock in operations.Purge
- #7688 memory: fix incorrect list entries when rooted at subdirectory
- #7690 memory: fix dst mutating src after server-side copy
- #7692 dropbox: fix chunked uploads when size <= chunkSize
Relatedly, workarounds have been put in place for the following backend
limitations that are unsolvable for the time being:
- #3262 drive is sometimes aware of trashed files/folders when it shouldn't be
- #6199 dropbox can't handle emojis and certain other characters
- #4590 onedrive API has longstanding bug for conflictBehavior=replace in
server-side copy/move
Before this change, the Memory backend's Copy method created a dst object that
referenced the src's objectData by pointer instead of making a copy. While this
minimized memory usage, an unintended consequence was that subsequently mutating
the src (such as changing the modtime) would inadvertently also mutate the dst,
and vice versa.
This change fixes the issue and adds a test.
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
This commit adds a new subcommand named "gitannex", aka
"git-annex-remote-rclone-builtin" when invoked via a symlink.
This accomplishes milestone 1 from issue #7625: "minimal support for the
external special remote protocol".
Issue #7625
1. The maximum number of objects on a page should be no more than
1000. Currently it is 1024, for this reason the listing always ends on
the first page with the error “object not found”, rclone tries to
upload the file again, Linkbox stores it with the name “filename(N)”,
and so the storage fills up indefinitely.
2. A hyphen is added to the list of allowed characters, that makes
queries more optimized (no need to load all files in a directory for
an entity with a hyphen).
The LinkBox API does not allow searching by more than 25 Unicode
characters in the name, for this reason it is currently impossible to
work with files and folders named longer than 8 Unicode chars (if
encoded in base32).
This fix queries all files in a directory for long names and checks
their names one by one, thus solving the issue.
Fixes#7542
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
Enhanced the UnmarshalJSON method for the Duration type to correctly
handle the special string 'off' and ensure large integers are parsed
accurately without floating-point rounding errors. This resolves
issues with setting and removing the MinAge filter through the rclone
rc command.
Fixes#3783
