Unfortunately multi part upload can't upload zero length files so
bring back the single part upload for zero length files only.
This was broken when we made all uploads multipart uploads.
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.
From testing it appears that CEPH no longer works properly with v2
auth and neither does Dreamhost, so update the docs anc configuration
to recommend v4 auth.
This is a problem when syncing a file which just needed its modtime
set with dropbox which can't set the mod time of a file without
re-uploading it.
Before this change we would delete the file, then the server side move
would fail moving the file to the backup-dir because it no longer
existed.
After this change the destination file is moved to the backup-dir
instead of being deleted and the new file is uploaded.
Fixes#2134
* All remotes now support RangeOption so remove SeekOption
* Correct off by one error as RangeOption arguments are inclusive.
* Use RangeSeek in preference to Seek if available
In a typical rclone copy to a bucket/container based remote, before
this change we were doing a list, followed by a HEAD of the bucket to
check it existed before doing the copy. The fact the list succeeded
means the bucket exists so mark it OK at that point.
Issue #1421
Before this change `rclone move localdir /mnt/different-fs` would
error. Now it falls back to moving individual files, which in turn
falls back to copying individual files across the filesystem boundary.
Because of a bug in the Onedrive API it will sometime report the wrong
size. If the size is wrong other remotes that depend on the size might
fail. To fix this we overwrite the objects size with the real size
from ContentLength header.
This was caused by inconsistent escaping of the URL in the prefix
check, so check the URL links back to the correct host and scheme
instead of the prefix check.
The decoded path check will catch any URLs which are outside of the
root.
This removes the old system of part accounting and replaces it with a
system of popping off the accounting reader and wrapping up new ones
as necessary.
This makes it much easier to carry the context down the chain of
wrapped readers and get the limiting as near as possible to the
output. This makes the accounting more accurate and the bandwidth
limiting smoother.
Fixes#2029 and Fixes#1443
