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`.
Before this change, NOTICE log messages during bisync dry runs were unclear as
to the direction of the skipped operation (Path1 to 2 vs. 2 to 1.) This change
adjusts the cmd/bisync/log.go indent function to be more expressive about
direction.
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.

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
mailru is unable to handle filenames with certain combining characters (for
example: йěáñ), and is therefore incapable of testing ApplyTransforms. (It is
also therefore incapable of fully supporting --no-unicode-normalization.)
The same override is applied to chunker when wrapping mailru.
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.
Before this change, nfsmount ignored the --volname flag. After this change, the --
volname flag is respected, making it possible to set a custom volume name.
macOS users should note that Finder will show the correct volume name in most
places, but a notable exception is the sidebar, which will show "localhost".
This seems to be a system limitation (at least without `sudo`), but see the
discussion at https://github.com/rclone/rclone/issues/7503#issuecomment-1933997678
for some possible workarounds.
Before this change, if a user unmounted externally (for example, via the Finder
UI), rclone would not be aware of this and wait forever to exit -- effectively
causing a deadlock that would require Ctrl+C to terminate.
After this change, when the handler detects an external unmount, it calls a
function which allows rclone to cleanly shutdown the VFS and exit.
