After an upload (notably multipart) to a slow backing remote, the file
lives in the VFS and is returned by ListBucket, but node.DirEntry() stays
nil until the --vfs-write-back writeback completes. HeadObject and
GetObject returned gofakes3.KeyNotFound while it was nil, so a HEAD/GET in
that window 404'd even though the object existed.
getFileHashByte already falls back to hashing the VFS cache when the
backing object isn't available yet. Drop the early nil return, pass the
node (not the fs.Object) to getFileHashByte, and take the Content-Type
from fs.MimeTypeFromName when the backing object isn't there yet.
TestS3Minio brings up a minio container via the fstest/testserver
framework, which exec's bash init.d scripts that shell out to docker.
This is not available on all platforms - Windows has no POSIX shell to
run the scripts, and macOS CI runners have no docker daemon - which
caused the build to fail there.
Add testy.SkipUnlessDocker to detect whether the framework can run and
skip the test when it cannot.
Previously serve s3 buffered every part of a multipart upload in memory
(in the gofakes3 S3 library) and concatenated them when the upload
completed, so memory use grew with the size of the upload.
serve s3 now streams the parts, in part-number order, into a single
PutStream upload to the underlying remote, which performs its own upload
with bounded memory. The whole file is never held in memory - memory use
is bounded by the parts in flight. This works for any remote that
supports PutStream (nearly all, including crypt) and for any part size,
so clients that don't produce uniform-sized parts (for example
PostgreSQL backup tools such as pgBarman and pgBackRest) work too.
Parts must arrive in ascending, contiguous part-number order; parts
uploaded out of order are buffered until their turn, and there is no
per-part retry (a failure aborts the whole upload). These trade-offs are
documented.
Passing --disable-multipart-streaming, or using a remote without
PutStream, reverts to buffering the parts in memory (the previous
behaviour); a one-off NOTICE is logged the first time this happens.
Fixes#7453
Run still uses a fresh local directory as the backing Fs that the
server wraps. RunWithBackend takes an extra remote name (e.g.
"TestS3Minio:") and uses a random subdirectory of that remote instead,
starting the matching fstest/testserver/init.d script on the way in
and tearing it down on the way out.
AuthProxy is only run for the local backend.
Before this change, if the user changed their password or public-key
and the auth proxy script returned updated config parameters for the
backend (eg a rotated api_key) rclone would continue to re-use the old
backend with the old config parameters out of the fscache.
This was because both the VFS cache and the fs/cache key were derived
from the user name only, so a change in the user's password or
public-key did not invalidate the cached backend.
Fix this by deriving the cache key from the user plus a hash of the
password/public-key, so a credential change forces a fresh backend.
The hash uses a per-process random HMAC key so the fragment that
appears in logs cannot be brute-forced offline.
When a SETSTAT request set the access and modification times, the
handler passed the modification time for both, discarding the
requested access time. Pass the requested access time through instead.
The VFS currently ignores the atime, but it might use it one day.
The statvfs@openssh.com extension was advertised but returned an
unsupported status, so clients couldn't query the amount of free and
used space. Implement it using the VFS Statfs method, which reports the
backend's usage where the backend supports About.
The SFTP serve handler ignored the size attribute of SETSTAT/FSETSTAT
requests, only acting on the modification time. This meant a client
asking to truncate a file (eg setting the final size of an upload, or
an explicit truncate) had no effect at all.
This respects the size attribute (if present) by truncating the file
to the requested size.
The SFTP serve write handler always opened files with O_TRUNC,
ignoring the flags requested in the SFTP OPEN packet. Some clients
(notably WinSCP's "Process in Background", which resumes an upload on
a second connection) re-open the partially written file without the
truncate flag and continue writing from the offset they had reached,
relying on the existing data being preserved. Forcing O_TRUNC zeroed
that prefix, so the start of the uploaded file ended up as a block of
zero bytes.
This fix respects the requested open flags instead so a resume open
without truncate keeps the already written data intact.

Previously the Mount RPC ignored the path component of the mount
request, so `server:/sub/dir` and `server:/` both landed at the root
of the served remote. The Mount handler now cleans the requested path
with path.Clean, looks it up in the VFS and serves a billy.Filesystem
rooted at that directory, refusing the mount if the path does not
exist or is not a plain directory.
A pathRewriter cache wraps the inner handle cache so that the same
file always produces the same NFS file handle regardless of which
mount minted it (and stable across server restarts for the disk and
symlink caches). This matches the traditional NFS expectation that a
subpath mount behaves like `cd` into a subtree.
nfsmount gains a --nfs-mount-path flag (default /) so clients can
select a subpath at mount time. This replaces a latent misuse of
--volname as the NFS mount path that was previously masked by the
server ignoring it.
Fixes#9442
Enable on-the-fly response compression for WebDAV when the client sends
Accept-Encoding and the response content type is suitable for
compression.
This adds compression for the WebDAV responses that benefit most in
practice, notably PROPFIND XML responses and text file downloads.
I tested this with Cyberduck, which sends
`Accept-Encoding: gzip,deflate` and accepted the compressed responses.
Range requests are explicitly left uncompressed.
Fixes#5777
The S3 ListObjects response from `rclone serve s3` was sorting object
contents by modification time instead of object key. This made the
listing order incompatible with S3 clients which expect lexicographic
key ordering.
In particular, `aws s3 sync` assumes both source and destination
iterators are ordered by key. With the old modtime ordering it could
misidentify files as missing or outdated and re-download objects that
were already up to date.
Change the pager to sort returned objects by key and add a regression
test which uses keys and modtimes arranged so the old behaviour would
fail.
Fixes#9002
Samsung TVs have a bug where they duplicate file extensions when both
the title contains an extension and the MIME type indicates the same
file type. For example, "photo.jpg" becomes "photo.jpg.jpg".
Remove extensions from <dc:title> while keeping them in the resource URL
and MIME type. This provides a cleaner display and prevents Samsung TVs
from incorrectly "fixing" what they perceive as missing extensions.
Samsung TVs have strict XML parsers that fail to interpret "
(numeric quote entity) correctly within DIDL-Lite metadata, causing
files to appear as empty folders. By replacing " with "
(named quote entity) in all marshaled XML, Samsung TVs can now
properly parse the metadata and display files.
This handles the "Big 5" XML entities that might cause parsing issues:
- " -> " (double quotes)
- ' -> ' (apostrophes)
- & -> & (ampersands)
- < -> < (less than)
- > -> > (greater than)
While Go's xml.Marshal already uses named entities for &, <, >
characters, this ensures complete protection against any edge cases
where numeric entities might be generated. Samsung TVs are known
to have strict XML parsers that can't handle numeric entities.
Fixes#9346
Samsung TVs sometimes send Browse requests with empty ObjectID
parameters (<ObjectID></ObjectID>) which causes DLNA servers to
return errors. Default empty ObjectID to "0" (root container) to
maintain compatibility.
This fix is based on ReadyMedia/MiniDLNA Bug 311 which documented
the same issue and solution for Samsung TVs.
See #9346
Add xmlns:sec="http://www.sec.co.kr/" namespace to DIDL-Lite responses
as required by Samsung TV DLNA implementations. This namespace is used
by working DLNA servers like MediaBrowser/Emby for Samsung compatibility.
Based on research of open source DLNA servers that successfully work
with Samsung TVs.
See #9346
Containers (directories) never had their Date field set, producing
<dc:date>0001-01-01</dc:date> (Go's zero time) in DIDL-Lite metadata.
This invalid date can confuse strict DLNA clients.
Set the dc:date to the directory's modification time, and as a safety
net, omit the dc:date element entirely when the timestamp is zero.
See #9346
The childCount attribute on DLNA containers was hardcoded to 1
regardless of how many items the directory actually contained. Some
DLNA clients (notably Samsung TVs) use childCount to decide whether
to browse into a container. Report the actual number of directory
entries instead.
See #9346
Samsung TVs are strict DLNA clients that expect SOAP response arguments
in the order defined by the service SCPD (Service Control Protocol
Description). The Browse response was using a Go map which produces
random iteration order, causing arguments like Result, NumberReturned,
TotalMatches, and UpdateID to appear in unpredictable order. Samsung TVs
fail to parse such responses and never proceed to browse directory
children, showing "no content" to the user.
Replace the map[string]string return type with an ordered []soapArg
slice throughout the UPnPService.Handle() interface, ensuring response
arguments always appear in SCPD-defined order.
See #9346
Replace AuthRequired bool with NoAuth bool on the rc.Call struct and
flip the auth check logic. Previously endpoints were unauthenticated
by default and had to opt in with AuthRequired: true, which led to
security vulnerabilities when developers forgot to set the flag.
Now all endpoints require authentication by default. Only explicitly
safe read-only endpoints are marked with NoAuth: true:
- rc/noop
- rc/error
- rc/list
- core/version
- core/stats
- core/group-list
- core/transferred
- core/du
- cache/stats
- vfs/list
- vfs/stats
- vfs/queue
- job/status
- job/list

Add a ctx parameter to vfs.New() so callers can pass in context
carrying ConfigInfo and FilterInfo. The context is stripped of
cancellation but config and filter values are preserved into a fresh
background context.
Add gzip compression for directory listings and text assets served over HTTP.
This reduces the rclone repository file listing from 40 kB to 8 kB and reduces
the rclone MANUAL.txt from 2.7 MB to 700 kB.
This makes listings and assets served across the network load faster.
The compression level of 5 should be a good balance between size and speed.
Browsers make a request to /favicon.ico when visiting pages generated
by the HTTP server.
Previously, if remotes did not have a /favicon.ico then the server
responded with a 404, causing browsers to show a default icon.
This adds a tiny fallback embedded PNG rclone favicon to help users
identify the rclone browser tab.
Previously if auth keys were provided without a comma then rclone
would only log an INFO message which could mean it went on to serve
without any auth.
The parsing for environment variables was changed in v1.70.0 to make
them work properly with multiple inputs. This means the input is
treated like a mini CSV file which works well except in this case when
the input has commas. This meant `user,auth` without quotes is treated
as two key pairs `user` and `quote`. The correct syntax is
`"user,auth"`. This updates the documentation accordingly.
As shown in
81e56a30c8/log.go (L74)
it seems like the wanted behaviour for merging arguments is the one of PrintLn,
which is "put a space between each arg"
Before, rclone serve would crash when sent a SIGHUP which contradicts
the documentation - saying it should flush the directory caches.
Moved signal handling from the mount into the vfs layer, which now
handles SIGHUP on all uses of the VFS including mount and serve.
Fixes#8607
add trailing slash to s3 ListObjectsV2 response because some clients expect a trailing forward slash to distinguish if the returned object is a directory
Fixes#8464
Fixed the anchor link in the documentation that points to the SSL/TLS section.
This change ensures the link directs correctly to the intended section (#tls-ssl) instead of the incorrect #ssl-tls.
No functional code changes, documentation only.
