Based on Issue 4087

Current behaviour is insecure. If the user specifies this value then we
switch to validating the server hostkey and so can detect server changes
or MITM-type attacks.
Before this change rclone used the relative path from the current
working directory.
It appears that WS FTP doesn't like this and the openssh sftp tool
also uses absolute paths which is a good reason for switching to
absolute paths.
This change reads the current working directory at startup and bases
all file requests from there.

For SSH authentication, `key_pem` should both override `key_file`
and not require other SSH authentication methods to be set.
Prior to this fix, rclone would attempt to use an ssh-agent
when `key_pem` was the only SSH authentication method set.
Fixes#4240
Before this change we early exited the SetModTime call which means we
skipped reading the info about the file.
This change reads info about the file in the SetModTime call even if
we are skipping setting the modtime.

This error started happening after updating golang/x/crypto which was
done as a side effect of:
3801b8109 vendor: update termbox-go to fix ncdu command on FreeBSD
This turned out to be a deliberate policy of making
ssh.ParsePrivateKeyWithPassphrase fail if the passphrase was empty.
See: https://go-review.googlesource.com/c/crypto/+/207599
This fix calls ssh.ParsePrivateKey if the passphrase is empty and
ssh.ParsePrivateKeyWithPassphrase otherwise which fixes the problem.
This also corrects the symlink detection logic to only check symlink
files. Previous to this it was checking all directories too which was
making it do more stat calls than was necessary.
This bug was introduced as part of adding context to the backends and
slipped through the net because the About call did not have an
interface assertion in the sftp backend.
I checked there were no other missing interface assertions on all the
optional methods on all the backends.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
Before this change we used Remove to remove directories. This works
fine on Unix based systems but not so well on Windows based ones.
Swap to using RemoveDirectory instead.
This unifies the 3 methods of reading config
* command line
* environment variable
* config file
And allows them all to be configured in all places. This is done by
making the []fs.Option in the backend registration be the master
source of what the backend options are.
The backend changes are:
* Use the new configmap.Mapper parameter
* Use configstruct to parse it into an Options struct
* Add all config to []fs.Option including defaults and help
* Remove all uses of pflag
* Remove all uses of config.FileGet
This was caused by using the sftp.File.Read method which resets the
streaming window after each call. Replacing it with sftp.File.WriteTo
and an io.Pipe fixes the problem bringing the speed to the same as the
sftp binary.
If md5sum/sha1sum fails we debug what it outputed on stderr and return
an empty hash indicating we didn't have a hash, rather than
hash.ErrUnsupported indicating that we don't support this hash type.
This fixes lots of ERROR messages for sftp and synology NAS which,
while it supports md5sum the SFTP paths and the SSH paths are
different so md5sum doesn't work.
We also stop disabling md5sum/sha1sum on errors since typically Hashes
is only checked at the start of a sync run and isn't expected to
change dynamically.
The sftp library delivers the attributes of the symlink rather than
the object pointed to in directory listings, however when we use Stat
from the library it points to the objects.
Previous to this fix this caused items pointed to by symlinks to be
unusable.
After the fix both symlinked files and directories work as expected.
A Range request can never request 0 bytes however this change was made
to make a clearer signal that the limit means read to the end.
Add test and more documentation and fixup uses
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
