Under Linux, rclone attempts to preallocate files for efficiency.
Before this change, pre-allocation would fail on ZFS with the error
Failed to pre-allocate: operation not supported
After this change rclone tries a different flag combination for ZFS
then disables pre-allocate if that doesn't work.
Fixes#3066
Before this change rclone would fail with
Failed to set modification time: InvalidObjectState: Operation is not valid for the source object's storage class
when attempting to set the modification time of an object in GLACIER.
After this change rclone will re-upload the object as part of a sync if it needs to change the modification time.

Before this change, rclone would return an error from the listing if
there was an unreadable directory, or if there was a problem stat-ing
a directory entry. This was frustrating because the command
completely aborts at that point when there is work it could do.
After this change rclone lists the directories and reports ERRORs for
unreadable directories or problems stat-ing files, but does return an
error from the listing. It does set the error flag which means the
command will fail (and objects won't be deleted with `rclone sync`).
This brings rclone's behaviour exactly in to line with rsync's
behaviour. It does as much as possible, but doesn't let the errors
pass silently.
Fixes#3179
Before this change we calculated all possible hashes for the file when
the `Hashes` method was called.
After we only calculate the Hash requested.
Almost all uses of `Hash` just need one checksum. This will slow down
`rclone lsjson` with the `--hash` flag. Perhaps lsjson should have a
`--hash-type` flag.
However it will speed up sync/copy/move/check/md5sum/sha1sum etc.
Before it took 12.4 seconds to md5sum a 1GB file, after it takes 3.1
seconds which is the same time the md5sum utility takes.
This fixes rclone returning `listing failed: strconv.ParseInt` errors
when listing files which have a malformed `src_last_modified_millis`.
This is uploaded by the client so care is needed in interpreting it as
it can be malformed.
Fixes#3065
In as many methods as possible we attempt to obey the Retry-After
header where it is provided.
This means that when objects are being requested from OVH cold storage
rclone will sleep the correct amount of time before retrying.
If the sleeps are short it does them immediately, if long then it
returns an ErrorRetryAfter which will cause the outer retry to sleep
before retrying.
Fixes#3041
This implements the Expiry interface so token expiry works properly
This change makes sure that this change from the swift library works
correctly with rclone's custom authenticator.
> Renew the token 60s before the expiry time
>
> The v2 and v3 auth schemes both return the expiry time of the token,
> so instead of waiting for a 401 error, renew the token 60s before this
> time.
>
> This makes transfers more efficient and also works around a bug in
> CEPH which returns 403 instead of 401 when the token expires.

Some WebDAV servers return an empty Available and Used which parses as 0.
This caused About to return the Total as 0 which can confused mounted
file systems.
After this change we ignore the result if Available and Used are both 0.

Before this change a race condition existed in mkdir
- the directory was attempted to be created
- the parent didn't exist so it failed
- the parent was created
- the directory was created again
The last step failed as the directory was created in a different thread.
This was fixed by checking the error messages of MKCOL for both
directory creations, rather than only the first.
Before this change a range request on a 0 length file would fail
$ rclone cat --head 128 drive:test/emptyfile
ERROR : open file failed: googleapi: Error 416: Request range not satisfiable, requestedRangeNotSatisfiable
To fix this we remove Range: headers on requests for zero length files.
This introduces a new config variable bucket_policy_only. If this is
set then rclone:
- ignores ACLs set on buckets
- ignores ACLs set on objects
- creates buckets with Bucket Policy Only set
