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.
Fixes#5671
This patch will:
- add --daemon-wait flag to control the time to wait for background mount
- remove dependency on sevlyar/go-daemon and implement backgrounding directly
- avoid setsid during backgrounding as it can result in race under Automount
- provide a fallback PATH to correctly run `fusermount` under systemd as it
runs mount units without standard environment variables
- correctly handle ^C pressed while background process is being setting up
Current way of checking whether mountpoint has been already mounted (directory
list) can result in race if rclone runs under Automount (classic or systemd).
This patch adopts Linux ProcFS for the check. Note that mountpoint is considered
empty if it's tagged as "mounted" by autofs. Also ProcFS is used to check whether
rclone mount was successful (ie. tagged by a string containing "rclone").
On macOS/BSD where ProcFS is unavailable the old method is still used.
This patch also moves a few utility functions unchanged to utils.go:
CheckOverlap, CheckAllowings, SetVolumeName.
This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error
message would then be something like:
mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Switched from talking about "unchanged" files to "identical" files.
I found out the hard way that the rclone copy will overwrite newer files.
Looking at posts in the rclone forum, this is a common experience.
The docs for copy have referred to "unchanged" files.
This is ambiguous because it intuitively introduces a sense
of chronology, but chronology is irrelevant.
Rclone only "cares" about difference, not change.
