Before this change we counted the final summary error as an error,
producing confusing log messages like:
Failed to check with 54 errors: last error was: 53 differences found
This change marks the summary error as already being counted, so the
error message becomes:
Failed to check with 53 errors: last error was: 53 differences found
This change also returns a listing failure in preference to a summary error.

After switching to a password callback function, if the ssh connection
aborts and needs to be reconnected then the user is-reprompted for their
password. Instead we now remember the password they entered and just give
that back. We do lose the ability for them to correct mistakes, but that's
the situation from before switching to callbacks. We keep the benefits
of not asking for passwords until the SSH connection succeeds (right
known_hosts entry, for example).
This required a small refactor of how `f := &Fs{}` was built, so we can
store the saved password in the Fs object
Before this change rclone returned the size from the Stat call of the
link. On Windows this reads as 0 always, however on unix it reads as
the length of the text in the link. This caused errors like this when
syncing:
Failed to copy: corrupted on transfer: sizes differ 0 vs 13
This change causes Windows platforms to read the link and use that as
the size of the link instead of 0 which fixes the problem.
Before this change
RCLONE_DRIVE_CHUNK_SIZE=111M rclone help flags | grep drive-chunk-size
Would show the default value, not the setting of RCLONE_DRIVE_CHUNK_SIZE
as the non backend flags do.
This change makes it work as expected by setting the default of the
option to the environment variable.
Fixes#4659
The missed update can cause incorrect before-cleaning cache stats
and a pre-mature condition broadcast in purgeOld before the cache
space use is reduced below the quota.
Add an exponentially increasing delay during retries up ENOSPC error
to avoid exhausting the 10 retries too soon when the cache space
recovery from item resets is not available from the file system yet
or consumed by other large cache writes.
Item reset is invoked by cache cleaner for synchronous recovery
from ENOSPC errors. The reset operation removes the cache file and
closes/reopens the downloaders. Although most parts of reset and
other item operations are done with the item mutex held, the mutex
is released during fd.WriteAt and downloaders calls. We used preAccess
and postAccess calls to serialize Reset, ReadAt, and Open, but missed
some other item operations. The patch adds preAccess/postAccess
calls in Sync, Truncate, Close, WriteAt, and rename.
A failed item reset is saved in the errItems for retryFailedResets
to process. If the item gets closed before the retry, the item may
have been removed from the c.item array. Previous code did not
account for this condition. This patch adds the check for the
exitence of the retry items in retryFailedResets.
The downloaders.Close() call acquires the downloaders' mutex before
calling the wait group wait and the main downloaders thread has a
periodical (5 seconds interval) call to kick its waiters and the
waiter dispatch function tries to get the mutex. So a deadlock can
occur if the Close() call starts, gets the mutex, while the main
downloader thread already got the timer's tick and proceeded to
call kickWaiters. The deadlock happens when the Close call gets
the mutex between the timer's kick and the main downloader thread
gets the mutex first. So it's a pretty short period of time and
it probably explains why the problem has not surfaced, maybe
something like tens of nanoseconds out of 5 seconds (~10^^-8).
It took 5 days of continued stressing the Close calls for the
deadlock to appear.
Adds a flag, --progress-terminal-title, that when used with --progress,
will print the string `ETA: %s` to the terminal title.
This also adds WriteTerminalTitle to lib/terminal

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 would emit the message
--checksum is in use but the source and destination have no hashes in common; falling back to --size-only
When the source or destination hash was missing as well as when the
source and destination had no hashes in common.
This first case is very confusing for users when the source and
destination do have a hash in common.
This change fixes that and makes sure the error message is not emitted
on missing hashes even when there is a hash in common.

This allows files to be copied by ID from google drive. These can be
copied to any rclone remote and if the remote is a google drive then
server side copy will be attempted.
Fixes#3625
