Before this change --update would transfer any file which was newer
than the destination regardless of whether it had changed or not.
This is needlessly wasteful of bandwidth.
After this change --update will only transfer files if they are newer
**and** they are different (checked with checksum and size).
'Couldn't find file - Need to Transfer' changed to 'Need to transfer -
File Not Found at Destination' because while reading the debug logs, it
confuses with failure in operation.
Before this change if -u/--update was in effect we compared the size
of the files to see if the transfer should go ahead. This was
comparing -1 with an actual size so the transfer always proceeded.
After this change we use the existing `sizeDiffers` function which
does the correct comparison with -1 for files of unknown length.

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 fix rclone calculated all the hashes on transfer. This
was particularly slow for the local backend.
After the fix we just calculate one hash which is enough for data
integrity.
This was factored from fstest as we were including the testing
enviroment into the main binary because of it.
This was causing opening the browser to fail because of 8243ff8bc8.
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.
Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.
For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.
This is done to make clear ownership over accounting object and prepare
for removing global stats object.
Stats elapsed time calculation has been altered to account for actual
transfer time instead of stats creation time.
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions
Context propagation is needed for stopping transfers and passing other
request-scoped values.
Before this change, when using rclone copy or move with --backup-dir
and the source was a single file, rclone would fail to use the backup
directory.
This change looks up the backup directory in the Fs cache and uses it
as appropriate.
This affects any commands which call operations.MoveFile or
operations.CopyFile which includes rclone move/moveto/copy/copyto
where the source is a single file.
Fixes#3219
Before this change we calculated the checksum which is potentially
time consuming and then ignored the result. After the change we don't
calculate the checksum if we are about to ignore it.
This will increase speed for backends which support ListR and will not
have the memory overhead of using --fast-list.
It also means that errors are queued until the end so as much of the
remote will be listed as possible before returning an error.
Commands affected are:
- lsf
- ls
- lsl
- lsjson
- lsd
- md5sum/sha1sum/hashsum
- size
- delete
- cat
- settier
This brings it up to par with lsjson.
This commit also reworks the framework to use ListJSON internally
which removes duplicated code and makes testing easier.
This puts a shim on the reader opened by Copy so that if an error is
returned, the reader is re-opened at the correct seek point.
This should make downloading very large files more reliable.
