Refactor sync/copy/move
* Don't load the src listing unless doing a sync and --delete-before
* Don't load the dst listing if doing copy/move and --no-traverse is set
`rclone --no-traverse copy src dst` now won't load either of the
listings into memory so will use the minimum amount of memory.
This change will reduce the amount of memory rclone uses dramatically
too as in normal operations (copy without --notraverse or sync) as it
no longer loads the source file listing into memory at all.
Fixes#8Fixes#544Fixes#546
Gives more accurate error propagation, control of depth of recursion
and short circuit recursion where possible.
Most of the the heavy lifting is done in the "fs" package, making file
system implementations a bit simpler.
This commit contains some code originally by Klaus Post.
Fixes#316
* Now removes identical copies without asking
* Now obeys `--dry-run`
* Implement `--dedupe-mode` for non interactive running
* `--dedupe-mode interactive` - interactive the default.
* `--dedupe-mode skip` - removes identical files then skips anything left.
* `--dedupe-mode first` - removes identical files then keeps the first one.
* `--dedupe-mode newest` - removes identical files then keeps the newest one.
* `--dedupe-mode oldest` - removes identical files then keeps the oldest one.
* `--dedupe-mode rename` - removes identical files then renames the rest to be different.
* Add tests which will only run on Google Drive.
* Make all integration tests start with an empty remote
* Add an -individual flag so this can be a different bucket/container/directory
* Fix up tests after changing the hashers
* Add sha1sum test
* Make directory checking in tests sleep more to fix acd inconsistencies
* Factor integration tests to make more maintainable
* Ensure remote writes have a fstest.CheckItems() before use
* this fixes eventual consistency on the directory listings later
* Call fs.Stats.ResetCounters() before every fs.Sync()
Note that the tests shouldn't be run concurrently as fs.Config is global state.
* Implement include/exclude
* Implement rsync compatible file globbing
* Implement command line filtering flags
* --delete-excluded - Delete files on dest excluded from sync
* --filter - Add a file-filtering rule
* --filter-from - Read filtering patterns from a file
* --exclude - Exclude files matching pattern
* --exclude-from - Read exclude patterns from file
* --include - Include files matching pattern
* --include-from - Read include patterns from file
* --files-from - Read list of source-file nam
* --min-size - Don't transfer any file smaller than this in k or suffix k|M|G
* --max-size - Don't transfer any file larger than this in k or suffix k|M|G
* Document
* Define Mover interface to move a single object
* Define DirMover interface to move a directory
* Implement DirMove operation
* Add `rclone move` command
* Tests for Dir Move
To Do
* Implement Move, DirMover in local, drive, dropbox
* unit test for Mover
* unit test for DirMover
This means that dropbox no longer stores MD5SUMs and modified times.
Fixup the tests so that blank MD5SUMs are ignored, and that if
Precision is set to a fs.ModTimeNotSupported, ModTimes can be ignored too.
This opens the door for other FSs which don't support metadata easily.
...unless had some errors or stats interval requested.
Add fs.ErrorLog to differentiate between Logs which should be
suppressed and errors which shouldn't.
Changed "ls" command not to show modification time by default only
size and path. That is because it is slow for nearly all the remotes
as it requires extra metadata lookup. All remotes can look up files
and sizes without extra operations.
Added "lsl" which does what "ls" used to - namely show modification
time, size and path.
Added "md5sum" which produces the same output as the md5sum command -
md5sums and paths that is.
