2 patches for repository davidsarah@dev.allmydata.org:/home/darcs/tahoe/trunk: Wed Jul 13 01:12:18 BST 2011 david-sarah@jacaranda.org * WUI: change the label of the button to unlink a file from 'del' to 'unlink'. Also change some internal names to 'unlink', and allow 't=unlink' as a synonym for 't=delete' in the web-API interface. Incidentally, improve a test to check for the rename button as well as the unlink button. fixes #1104 Wed Jul 13 01:27:22 BST 2011 david-sarah@jacaranda.org * docs: some changes of 'delete' or 'rm' to 'unlink'. refs #1104 New patches: [WUI: change the label of the button to unlink a file from 'del' to 'unlink'.

Replace "descriptor" with "server". Other replacements: get_all_servers -> get_connected_servers/get_known_servers get_servers_for_index -> get_servers_for_psi (now returns IServers) This change still needs to be pushed further down: lots of code is now getting the IServer and then distributing (peerid, rref) internally. Instead, it ought to distribute the IServer internally and delay extracting a serverid or rref until the last moment. no_network.py was updated to retain parallelism. ] [TAG allmydata-tahoe-1.8.2 warner@lothar.com**20110131020101] Patch bundle hash: 1bd3d89e65fcd55f6ab19a05c274d8a1f0928611
