Before this change rclone would read the list of files from the
files-from parameter and check they existed one at a time. This could
take a very long time for lots of files.
After this change, rclone will check up to --checkers in parallel.
Before this change using --files-from would scan all the directories
that the files could possibly be in causing rclone to do more work
that was necessary.
After this change, rclone constructs an in memory tree using the
--fast-list mechanism but from all of the files in the --files-from
list and without scanning any directories.
Any objects that are not found in the --files-from list are ignored
silently.
This mechanism is used for sync/copy/move (march) and all of the
listing commands ls/lsf/md5sum/etc (walk).
Somehow in the code reorganisation of
11da2a6c9b the check for --min-age and
--max-age got switched around. This commit fixes that and means you
can use --min-age and --max-age together.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
