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

This command executes a list query in Google Drive’s native query
language and returns a JSON dump of matches. It’s useful for locating
files quickly in folders with a large number of files, where rclone’s
normal list command is slow due to client-side filtering.
Before this change, Hasher did not check whether a "passed hash" (hashtype
natively supported by the wrapped backend) returned from a backend was blank,
and would sometimes return a blank hash to the caller even when a non-blank hash
was already stored in the db. This caused issues with, for example, Google
Drive, which has SHA1 / SHA256 hashes for some files but not others
(https://rclone.org/drive/#sha1-or-sha256-hashes-may-be-missing) and sometimes also
does not have hashes for very recently modified files.
After this change, Hasher will check if the received "passed hash" is
unexpectedly blank, and if so, it will continue to try other enabled methods,
such as retrieving a value from the database, or possibly regenerating it.

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.
This change adds support for metadata on OneDrive. Metadata (including
permissions) is supported for both files and directories.
OneDrive supports System Metadata (not User Metadata, as of this writing.) Much
of the metadata is read-only, and there are some differences between OneDrive
Personal and Business (see table in OneDrive backend docs for details).
Permissions are also supported, if --onedrive-metadata-permissions is set. The
accepted values for --onedrive-metadata-permissions are read, write, read,write, and
off (the default). write supports adding new permissions, updating the "role" of
existing permissions, and removing permissions. Updating and removing require
the Permission ID to be known, so it is recommended to use read,write instead of
write if you wish to update/remove permissions.
Permissions are read/written in JSON format using the same schema as the
OneDrive API, which differs slightly between OneDrive Personal and Business.
(See OneDrive backend docs for examples.)
To write permissions, pass in a "permissions" metadata key using this same
format. The --metadata-mapper tool can be very helpful for this.
When adding permissions, an email address can be provided in the User.ID or
DisplayName properties of grantedTo or grantedToIdentities. Alternatively, an
ObjectID can be provided in User.ID. At least one valid recipient must be
provided in order to add a permission for a user. Creating a Public Link is also
supported, if Link.Scope is set to "anonymous".
Note that adding a permission can fail if a conflicting permission already
exists for the file/folder.
To update an existing permission, include both the Permission ID and the new
roles to be assigned. roles is the only property that can be changed.
To remove permissions, pass in a blob containing only the permissions you wish
to keep (which can be empty, to remove all.)
Note that both reading and writing permissions requires extra API calls, so if
you don't need to read or write permissions it is recommended to omit --onedrive-
metadata-permissions.
Metadata and permissions are supported for Folders (directories) as well as
Files. Note that setting the mtime or btime on a Folder requires one extra API
call on OneDrive Business only.
OneDrive does not currently support User Metadata. When writing metadata, only
writeable system properties will be written -- any read-only or unrecognized keys
passed in will be ignored.
TIP: to see the metadata and permissions for any file or folder, run:
rclone lsjson remote:path --stat -M --onedrive-metadata-permissions read
See the OneDrive backend docs for a table of all the supported metadata
properties.
