This should be all that's needed to +handle the case where there is a transfer remote on the internet somewhere, +and a locally paired client on the LAN. As long as the paired repository +has a lower cost value, it will be sent any new file first, and if that +is the only client, the file will not be sent to the transfer remote at +all. + +But.. locally paired repos did not have a lower cost set, at all. +So I made their cost be set to 175 when they're created. Anyone +who already did local pairing should make sure the Repositories +list shows locally paired repositories above transfer remotes. + +Which brought me to needing an easy way to reorder that list of remotes, +which I plan to do by letting the user drag and drop remotes around, +which will change their cost accordingly. Implementing that has two +pain points: + +1. Often a lot of remotes will have the same default cost value. + So how to insert a remote in between two that have cost 100? + This would be easy if git-annex didn't have these cost numbers, + and instead just had an ordered list of remotes.. but it doesn't. + Instead, dragging remotes in the list will sometimes need to change + the costs of others, to make room to insert them in. It's BASIC + renumbering all over again. So I wrote some code to do this with as + little bother as possible. + +2. Drag and drop means javascript. I got the basics going quickly with + jquery-ui, only to get stuck for over an hour on some CSS issue + that made lines from the list display all weird while being dragged. + It is always something like this with javascript.. + +So I've got these 2 peices working, and even have the AJAX call +firing, but it's not quite wired up just yet. Tomorrow. |
