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.

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.
Before this change, operations.DirMove would fail when moving a directory, if
the src and dest were on different upstreams of a combine remote.
The issue only affected operations.DirMove, and not sync.MoveDir, because they
checked for server-side-move support in different ways.
MoveDir checks by just trying it and seeing what error comes back. This works
fine for combine because combine returns fs.ErrorCantDirMove which MoveDir
understands what to do with.
DirMove, however, only checked whether the function pointer is nil. This is an
unreliable way to check for combine, because combine does advertise support for
DirMove, despite not always being able to do it.
This change fixes the issue by checking the returned error in a manner similar
to sync.MoveDir and falling back to individual file moves (copy + delete)
depending on which error was returned.
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.
Before this change, directory modtimes (and metadata) were always synced from
src to dst, even if already in sync (i.e. their modtimes already matched.) This
potentially required excessive API calls, made logs noisy, and was potentially
problematic for backends that create "versions" or otherwise log activity
updates when modtime/metadata is updated.
After this change, a new DirsEqual function is added to check whether dirs are
equal based on a number of factors such as ModifyWindow and sync flags in use.
If the dirs are equal, the modtime/metadata update is skipped.
For backends that require setDirModTimeAfter, the "after" sync is performed only
for dirs that could have been changed by the sync (i.e. dirs containing files
that were created/updated.)
Note that dir metadata (other than modtime) is not currently considered by
DirsEqual, consistent with how object metadata is synced (only when objects are
unequal for reasons other than metadata).
To sync dir modtimes and metadata unconditionally (the previous behavior), use
--ignore-times.
Before this change, the VFS layer did not properly handle unicode normalization,
which caused problems particularly for users of macOS. While attempts were made
to handle it with various `-o modules=iconv` combinations, this was an imperfect
solution, as no one combination allowed both NFC and NFD content to
simultaneously be both visible and editable via Finder.
After this change, the VFS supports `--no-unicode-normalization` (default `false`)
via the existing `--vfs-case-insensitive` logic, which is extended to apply to both
case insensitivity and unicode normalization form.
This change also adds an additional flag, `--vfs-block-norm-dupes`, to address a
probably rare but potentially possible scenario where a directory contains
multiple duplicate filenames after applying case and unicode normalization
settings. In such a scenario, this flag (disabled by default) hides the
duplicates. This comes with a performance tradeoff, as rclone will have to scan
the entire directory for duplicates when listing a directory. For this reason,
it is recommended to leave this disabled if not needed. However, macOS users may
wish to consider using it, as otherwise, if a remote directory contains both NFC
and NFD versions of the same filename, an odd situation will occur: both
versions of the file will be visible in the mount, and both will appear to be
editable, however, editing either version will actually result in only the NFD
version getting edited under the hood. `--vfs-block-norm-dupes` prevents this
confusion by detecting this scenario, hiding the duplicates, and logging an
error, similar to how this is handled in `rclone sync`.
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
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.
This should be more efficient for the purposes of --fix-case, as operations.DirMove
accepts `srcRemote` and `dstRemote` arguments, while sync.MoveDir does not.
This also factors the two-step-move logic to operations.DirMoveCaseInsensitive, so
that it is reusable by other commands.
This adds a step to detect whether the backend is capable of supporting the
feature, and skips the test if not. A backend can be incapable if, for example,
it is non-case-preserving or automatically converts NFD to NFC.
This change moves the --retries and --retries-sleep flags/variables from cmd to
config (consistent with --low-level-retries), so that they can be more easily
referenced from subcommands.
It appears that ci.DryRun = true affects the behavior of r.WriteObject on
chunker only, and no other remotes. This change puts a quick bandaid on it by
setting it later on in the test, but perhaps the underlying issue warrants a
closer look at some point... is chunker checking ci.DryRun itself in a way that
no other remote does? If so, should it? (Does this break encapsulation?)
Before this change, operations.moveOrCopyFile had a special section to detect
and handle changing case of a file on a case insensitive remote, but
operations.Move did not. This caused operations.Move to fail for certain
backends that are incapable of renaming a file in-place to an equal-folding name.
(Not all case-insensitive backends have this limitation -- for example, Dropbox
does but macOS local does not.)
After this change, the special two-part-move section from
operations.moveOrCopyFile is factored out to its own function,
moveCaseInsensitive, which is then called from both operations.moveOrCopyFile
and operations.Move.
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.
Before this change, bisync could only detect changes based on modtime, and
would refuse to run if either path lacked modtime support. This made bisync
unavailable for many of rclone's backends. Additionally, bisync did not account
for the Fs's precision when comparing modtimes, meaning that they could only be
reliably compared within the same side -- not against the opposite side. Size
and checksum (even when available) were ignored completely for deltas.
After this change, bisync now fully supports comparing based on any combination
of size, modtime, and checksum, lifting the prior restriction on backends
without modtime support. The comparison logic considers the backend's
precision, hash types, and other features as appropriate.
The comparison features optionally use a new --compare flag (which takes any
combination of size,modtime,checksum) and even supports some combinations not
otherwise supported in `sync` (like comparing all three at the same time.) By
default (without the --compare flag), bisync inherits the same comparison
options as `sync` (that is: size and modtime by default, unless modified with
flags such as --checksum or --size-only.) If the --compare flag is set, it will
override these defaults.
If --compare includes checksum and both remotes support checksums but have no
hash types in common with each other, checksums will be considered only for
comparisons within the same side (to determine what has changed since the prior
sync), but not for comparisons against the opposite side. If one side supports
checksums and the other does not, checksums will only be considered on the side
that supports them. When comparing with checksum and/or size without modtime,
bisync cannot determine whether a file is newer or older -- only whether it is
changed or unchanged. (If it is changed on both sides, bisync still does the
standard equality-check to avoid declaring a sync conflict unless it absolutely
has to.)
Also included are some new flags to customize the checksum comparison behavior
on backends where hashes are slow or unavailable. --no-slow-hash and
--slow-hash-sync-only allow selectively ignoring checksums on backends such as
local where they are slow. --download-hash allows computing them by downloading
when (and only when) they're otherwise not available. Of course, this option
probably won't be practical with large files, but may be a good option for
syncing small-but-important files with maximum accuracy (for example, a source
code repo on a crypt remote.) An additional advantage over methods like
cryptcheck is that the original file is not required for comparison (for
example, --download-hash can be used to bisync two different crypt remotes with
different passwords.)
Additionally, all of the above are now considered during the final --check-sync
for much-improved accuracy (before this change, it only compared filenames!)
Many other details are explained in the included docs.
Before this change, a file would sometimes be silently deleted instead of
renamed on macOS, due to its unique handling of unicode normalization. Rclone
already had a SameObject check in place for case insensitivity before deleting
the source (for example if "hello.txt" was renamed to "HELLO.txt"), but had no
such check for unicode normalization. After this change, the delete is skipped
on macOS if the src and dst filenames normalize to the same NFC string.

Similar to
acf1e2df84,
go1.21.4 appears to have broken sync.MoveDir on Windows because
filepath.VolumeName() returns `\\?` instead of `\\?\C:` in cleanRootPath. It
looks like the Go team is aware of the issue and planning a fix, so this may
only be needed temporarily.
Before this change, a sync to a case insensitive dest (such as macOS / Windows)
would not result in a matching filename if the source and dest had casing
differences but were otherwise equal. For example, syncing `hello.txt` to
`HELLO.txt` would result in the dest filename remaining `HELLO.txt`.
Furthermore, `--local-case-sensitive` did not solve this, as it actually caused
`HELLO.txt` to get deleted!
After this change, `HELLO.txt` is renamed to `hello.txt` to match the source,
only if the `--fix-case` flag is specified. (The old behavior remains the
default.)
Before this change, changing the case of a file on a case insensitive remote
would fatally panic when `--dry-run` was set, due to `moveOrCopyFile`
attempting to access the non-existent `tmpObj` it (would normally have)
created. After this change, the panic is avoided by skipping this step during
a `--dry-run` (with the usual "skipped as --dry-run is set" log message.)
Allows rclone sync to accept the same output file flags as rclone check,
for the purpose of writing results to a file.
A new --dest-after option is also supported, which writes a list file using
the same ListFormat flags as lsf (including customizable options for hash,
modtime, etc.) Conceptually it is similar to rsync's --itemize-changes, but
not identical -- it should output an accurate list of what will be on the
destination after the sync.
Note that it has a few limitations, and certain scenarios
are not currently supported:
--max-duration / CutoffModeHard
--compare-dest / --copy-dest (because equal() is called multiple times for the
same file)
server-side moves of an entire dir at once (because we never get the individual
file objects in the dir)
High-level retries, because there would be dupes
Possibly some error scenarios that didn't come up on the tests
Note also that each file is logged during the sync, as opposed to after, so it
is most useful as a predictor of what SHOULD happen to each file
(which may or may not match what actually DID.)
Only rclone sync is currently supported -- support for copy and move may be
added in the future.
Logger instruments the Sync routine with a status report for each file pair,
making it possible to output a list of the synced files, along with their
attributes and sigil categorization (match/differ/missing/etc.)
It is very customizable by passing in a custom LoggerFn, options, and
io.Writers to be written to. Possible uses include:
- allow sync to write path lists to a file, in the same format as rclone check
- allow sync to output a --dest-after file using the same format flags as lsf
- receive results as JSON when calling sync from an internal function
- predict the post-sync state of the destination
For usage examples, see bisync.WriteResults() or sync.SyncLoggerFn()
Before this change, --no-unicode-normalization and --ignore-case-sync
were respected for rclone check but not for rclone check --checkfile,
causing them to give different results.
This change adds support for --checkfile so that the behavior is consistent.
Before this change, lsf's time format was hard-coded to "2006-01-02 15:04:05",
regardless of the Fs's precision. After this change, a new optional
--time-format flag is added to allow customizing the format (the default is
unchanged).
Examples:
rclone lsf remote:path --format pt --time-format 'Jan 2, 2006 at 3:04pm (MST)'
rclone lsf remote:path --format pt --time-format '2006-01-02 15:04:05.000000000'
rclone lsf remote:path --format pt --time-format '2006-01-02T15:04:05.999999999Z07:00'
rclone lsf remote:path --format pt --time-format RFC3339
rclone lsf remote:path --format pt --time-format DateOnly
rclone lsf remote:path --format pt --time-format max
--time-format max will automatically truncate '2006-01-02 15:04:05.000000000'
to the maximum precision supported by the remote.
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.
