Before this change, macOS-specific metadata was not preserved by rclone, even for
local-to-local transfers (it does not use the "user." prefix, nor is Mac metadata
limited to xattrs.) Additionally, rclone did not take advantage of APFS's native
"cloning" functionality for fast and deduplicated transfers.
After this change, local (on macOS only) supports "server-side copy" similarly to
other remotes, and achieves this by using (when possible) macOS's native APFS
"cloning", which is the same underlying mechanism deployed when a user
duplicates a file via the Finder UI. This has several advantages over the
previous behavior:
- It is extremely fast (even large files can be cloned instantly)
- It is very efficient in terms of storage, as it automatically deduplicates when
possible (i.e. so that having two identical files does not consume more storage
than having just one.) (The concept is similar to a "hard link", but subsequent
modifications will not affect the original file.)
- It preserves Mac-specific metadata to the maximum degree, including not only
xattrs but also metadata not easily settable by other methods, including Finder
and Spotlight params.
When server-side "clone" is not available (for example, on non-APFS volumes), it
falls back to server-side "copy" (still preserving metadata but using more disk
storage.) It is only used when both remotes are local (and not wrapped by other
remotes, such as crypt.) The behavior of local on non-mac systems is unchanged.
This adds a new optional parameter to the backend, to specify a path
to a unix domain socket to connect to, instead the specified URL.
The URL itself is still used for the rest of the HTTP client, allowing
host and subpath to stay intact.
This allows using rclone with the webdav backend to connect to a WebDAV
server provided at a Unix Domain socket:
rclone serve webdav --addr unix:///tmp/my.socket remote:path
rclone --webdav-unix-socket /tmp/my.socket --webdav-url http://localhost lsf :webdav:
This converts the ChunkedReader into an interface and provides two
implementations one sequential and one parallel.
This can be used to improve the performance of the VFS on high
bandwidth or high latency links.
Fixes#4760
There were a lot of instances of this lint error
printf: non-constant format string in call to github.com/rclone/rclone/fs.Logf (govet)
Which were fixed by re-arranging the arguments and adding "%s".
There were quite a few genuine bugs which were found too.
In corporate environments, client certificates have short life times
for added security, and they get renewed automatically. This means
that client certificate can expire in the middle of long running
command such as `mount`.
This commit attempts to reload the client certificates 30s before they
expire.
This will be active for all backends which use HTTP.
After re-organising the config it became apparent that there was a bug
in the config system which hadn't manifested until now.
This was the default config overriding the main config and was fixed
by noting when the defaults had actually changed.
Apparently fmt.Sscanln doesn't parse bool's properly and this isn't
likely to be fixed by the Go team who regard sscanf as a mistake.
This only uses sscan for integers and uses the correct routine for
everything else.
This also implements parsing time.Duration

Previously this used `rclone test makefiles --seed 0` which sets a
random seed and every now and again we get this error
Failed to open file "$WORK\\src\\moru": open $WORK\src\moru: is a directory
Because a file with the same name was created as a file in the src and
a dir in the dst.
This fixes it by using determinstic seeds each time.
Before this change backends which supported more than one hash (eg
pcloud) or backends which wrapped backends supporting more than one
hash (combine) would fail the TestMultithreadCopy and
TestMultithreadCopyAbort with an error like
Failed to make new multi hasher: requested set 000001ff contains unknown hash types
This was caused by the tests limiting the globally available hashes to
the first hash supplied by the backend.
This was added in this commit
d5d28a7513 operations: fix overwrite of destination when multi-thread transfer fails
to overcome the tests taking >100s on the local backend because they
made every single hash that the local backend. It brought this time
down to 20s.
This commit fixes the problem and retains the CPU speedup by only
applying the fix from the original commit if the destination backend
is the local backend. This fixes the common case (testing on the local
backend). This does not fix the problem for a backend which wraps the
local backend (eg combine) but this is run only on the integration
test machine and not on all the CI.
Before this fix we attempted to copy metadata to SFTP backends despite
them not being capable of it.
This fixes the problem by making the need to copy metadata explicit
rather than implicit in a value being present or not.
In this commit
6a0a54ab97 operations: fix missing metadata for multipart transfers to local disk
We broke the setting of modification times when doing multipart
transfers from a backend which didn't support metadata to a backend
which did support metadata.
This was fixed by setting the "mtime" in the metadata if it was
missing.
