In some owncloud server setups multiple concurrent connections for the
same session are not supported: owncloud/core#11153
This causes issues with multiple uploads and downloads. A usual symptom
is the quota job failing and the sync aborting.
This workaround lets activity on the propagator's GET and PUT jobs
reset the timeout of all network jobs. That way, queries like the quota
job would not time out while a large up/download is in progress.
The real bug in #2219 actually was that the gui allowed users to
choose to not sync the root folder. That's not supported and no
longer possible in the UI.
Instead you may now sync a folder's files without syncing its sub-
folders.
See #2167 and #2169.
* csync_detect_update: Reupload a file if the sizes differ, similar
to how we reupload if the mtimes differ.
* PropagateUploadFileQNAM::slotPutFinished(): Abort an upload if the
size changed, similar to how we abort an upload if the mtimes changed.
* Downloadinfo entries for files that no longer need to be downloaded
are useless and can be removed. In particular, the temporary files
holding partially retrieved files are now deleted when no longer
necessary.
* The same is true for blacklist entries for paths that are no longer
being discovered.
* Same for uploadinfos for files that no longer need to be uploaded.
On signout, syncs that are running in folders are aborted. That used to
also switch the state of these folders to 'paused'. To fix that, aborts
that are caused by user actions no longer change the folder paused
state.
Aborts due to errors should still pause folders! Otherwise we'd try
resyncing them even though there was an error.
Syncing without the system exclude file would cause lots of trouble.
For instance we would try uploading the temporary files we store
partially completed downloads in.
