Brian Warner |warner| pointed out Tahoe-LAFS sends a keepalive packet once every eight (8) minutes. This setting is configurable via "timeout.keepalive" as noted in "docs/configuration.rst". .. |warner| image:: warner.png :height: 35 :alt: Brian Warner :target: http://tahoe-lafs.org/trac/tahoe-lafs/wiki/AboutUs .. _`information regarding Tahoe-LAFS' use of keepalives`: https://tahoe-lafs.org/pipermail/tahoe-dev/2012-July/007513.html Switching from Introducers to Gossip - ------------------------------------ Brian `proposes switching from introducers to gossip`_. Brian's idea is for all nodes to offer a "grid-control" service. "grid-control" allows you to publish Announcements, either your own or ones you are forwarding for someone one else. Brian proposes several approaches to this concept: * fully-connected mesh: every node makes a Foolscap connection to every grid-control provider they hear about, subscribe to hear about all announcements, and publish any announcements that the other side doesn't already know about. * opportunistic: clients only connect to storage servers, and storage servers don't make outbound connections to anybody, but if you *do* happen to be connected to someone who also offers "grid-control", then connect to their grid-control object too and exchange Announcements * cluster-of-Introducers: normal nodes don't offer grid-control, but multiple Introducers do, and all of them know about each other. All nodes connect to all grid-control providers (which means all Introducers). * one Introducer: this is just a degenerate cluster-of-Introducers .. _`proposes switching from introducers to gossip`: https://tahoe-lafs.org/pipermail/tahoe-dev/2012-July/007511.html grid-updates - ------------ darrob `announced the release of grid-updates 1.1.3`_. grid-updates is Tahoe-LAFS helper program. Originally a shell script, darrob rewrote the program in Python, so it runs on all platforms supported by Tahoe-LAFS. grid-updates helps manage volunteer grids. It's core feature is downloading and uploading the node's introducer list and has a new feature of downloading lists for shares and repairing them. darrob is testing the program against 1.9.2a1. The program is packaged for Windows, Arch and Debian. .. _`announced the release of grid-updates 1.1.3`: https://tahoe-lafs.org/pipermail/tahoe-dev/2012-June/007505.html Patches Needing Review of the Week ================================== There is one (1) ticket still needing review for 1.9.2: * `#1778`_: increase maximum mutable share size There are six (6) ticket still needing review for 1.10.0: * `#1777`_: cleanups to tests and mutables for 1.10 * `#166`_: command line order is problematic * `#937`_: 'tahoe run' doesn't work for an introducer node * `#1539`_: stop putting pkg_resources.require() into .tac files * `#1159`_: stop using .tac files: make it possible to change appname, Python package-directory name, perhaps other names * `#1693`_: flogtool doesn't get automatically provided There are two (2) tickets still needing review of 1.11.0: * `#1265`_: New Visualizer is insufficiently labelled/documented (plus layout problem) * `#1382`_: immutable peer selection refactoring and enhancements .. _`#1778`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1778 .. _`#1777`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1777 .. _`#166`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/166 .. _`#937`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/937 .. _`#1539`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1539 .. _`#1159`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1159 .. _`#1693`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1693 .. _`#1265`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1265 .. _`#1382`: http://tahoe-lafs.org/trac/tahoe-lafs/ticket/1382 - ---- *The Tahoe-LAFS Weekly News is published once a week by The Tahoe-LAFS* *Software Foundation, President and Treasurer: Peter Secor* |peter| *.
