Before this change we didn't calculate or check hashes of transferred
files if --size-only mode was explicitly set.
This problem was introduced in 20da3e6352 which was released with v1.37
After this change hashes are checked for all transfers unless
--ignore-checksums is set.
Before this change we calculated the checkums when using
--ignore-checksum but ignored them at the end.
Now we don't calculate the checksums at all which is more efficient.
Before this change for a post copy Hash check we would run the hashes sequentially.
Now we run the hashes in parallel for a useful speedup.
Note that this refactors the hash check in Copy to use the standard
hash checking routine.
Before this change, if the caller didn't provide a hint, we would
calculate all hashes for reads and writes.
The new whirlpool hash is particularly expensive and that has become noticeable.
Now we don't calculate any hashes on upload or download unless hints are provided.
This means that some operations may run slower and these will need to be discovered!
It does not affect anything calling operations.Copy which already puts
the corrects hints in.
Before this change `rclone rc --loopback` would give the error "bad
JSON".
This was because the output of the `rc/list` command was not serialzed
through JSON.
This serializes it through JSON and fixes that (and probably other)
command.
The error "tls: bad record MAC" is very likely to be caused by
hardware issues. It indicates that a packet got corrupted somewhere.
As a work around, this change treats it as retriable error which
allows the chunk to get retried and the transfer to continue.
See: https://forum.rclone.org/t/rc-rc-job-expire-interval-bug/11188
rclone was ignoring the --rc-job-expire-duration and --rc-job-interval
flags. This turned out to be an initialization order problem and was
fixed by moving those flags out of global config into rc config.
rc: WebGUI should check for new update only when rc-web-gui-update is specified or not already downloaded.
rc: change permission to 0755 instead of 755 to prevent unexpected behaviour.
