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.

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.
This is so that they can import cmd/serve without causing an import
loop.
The active servers can now be configured by commenting lines out in
cmd/all/all.go like all the other commands.
An incorrect nil check was spotted while reviewing the code for
CVE-2024-45337.
The nil check failing has never happened as far as we know. The
consequences would be a nil pointer exception.
It fails to build on plan9, which is part of the rclone CI matrix, and
the PR fixing it upstream doesn't seem to be getting traction.
Stub it on our side, we can still remove this once it gets merged.
This also
- move in use options (Opt) from vfsflags to vfscommon
- change os.FileMode to vfscommon.FileMode in parameters
- rework vfscommon.FileMode and add tests
Before this change, if a hardlink command was issued, rclone would
just ignore it and not return an error.
This changes any unknown operations (including hardlink) to return an
unsupported error.
Before this change uploading files with rclone to:
rclone serve sftp --vfs-cache-mode full
Would return the error:
command "md5sum XXX" failed with error: unexpected non file
This patch detects that the file is still in the VFS cache and reads
the MD5SUM from there rather from the remote.
Fixes#7241
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.
This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Before this change, rclone serve sftp operating with a new rclone
after the md5sum/sha1sum detection was reworked to just run a plain
`md5sum`/`sha1sum` command in
3ea82032e7 sftp: support md5/sha1 with rsync.net #3254
Failed to signal to the remote that md5sum/sha1sum wasn't supported as
in
71e172a139 serve/sftp: support empty "md5sum" and "sha1sum" commands
We unconditionally return good hashes even if the remote being served
doesn't support the hash type in question.
This fix checks the hash type is supported and returns an error
MD5 hash not supported
When the backend is first contacted this will cause the sftp backend
to detect that the hash type isn't available.
Unfortunately this may have cached the wrong state so editing or
remaking the config may be necessary to fix it.
strings.ReplaceAll(s, old, new) is a wrapper function for
strings.Replace(s, old, new, -1). But strings.ReplaceAll is more
readable and removes the hardcoded -1.

This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
Before this fix, rclone only generated an RSA server key when the user
didn't supply a key.
However the RSA server key is being deprecated as it is now insecure.
This patch generates an ECDSA server key too which will be used in
preference over the RSA key, but the RSA key will carry on working.
