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.
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.
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
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
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.

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.
Before this change, operations.CopyDirMetadata would fail with: `internal error:
expecting directory string from combine root '' to have SetMetadata method:
optional feature not implemented` if the dst was the root directory of a combine
upstream. This is because combine was returning a *fs.Dir, which does not
satisfy the fs.SetMetadataer interface.
While it is true that combine cannot set metadata on the root of an upstream
(see also #7652), this should not be considered an error that causes sync to do
high-level retries, abort without doing deletes, etc.
This change addresses the issue by creating a new type of DirWrapper that is
allowed to fail silently, for exceptional cases such as this where certain
special directories have more limited abilities than what the Fs usually
supports.
It is possible that other similar wrapping backends (Union?) may need this same
fix.
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.

Before this change, undecryptable file names would be skipped very quietly
(there was a log warning, but only at DEBUG level),
failing to alert users of a potentially serious issue that needs attention.
After this change, the log level is raised to NOTICE by default and a new
--crypt-strict-names flag allows raising an error, for users who may prefer not
to proceed if such an issue is detected.
See https://forum.rclone.org/t/skipping-undecryptable-file-name-should-be-an-error/27115https://github.com/rclone/rclone/issues/5787
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.
Before this change, moving (renaming) a file or folder to a different name
within the same parent directory would fail, due to using the wrong API
operation ("/file/move_copy.json" and "/folder/move_copy.json", instead of the
separate "/file/rename.json" and "/folder/rename.json" that opendrive has for
this purpose.)
After this change, Move and DirMove check whether the move is within the same
parent dir. If so, "rename" is used. If not, "move_copy" is used, like before.
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.

A seafile server can be configured to use a relative URL as
FILE_SERVER_ROOT in order to support more than one hostname/ip. (see
https://github.com/haiwen/seahub/issues/3398#issuecomment-506920360 )
The previous backend implementation always expected an absolute
download/upload URL, resulting in an "unsupported protocol scheme"
error.
With this commit it supports both absolute and relative.
