Replication Technologies for TWiki

See all CategoryReplication topics.

Motivation

ReadWriteOfflineWiki has been a goal for many of us wanting to use TWiki from a disconnected laptop.

A good technology of these would facilitate exchange of TWiki pages between desktops, eliminating the need for a hosted server. Some do continuous synchronization with ftp: an ingeneous bit of coding with one could thus facilitate ReadWriteOfflineWiki.

Options

There may be an opensource replication technology TWiki can layer on. Else an inexpensive shareware on would be good:

• ReplicationUsingUnison contains Martin Cleaver's notes on syncing with Unison.
• ReplicationUsingRsync is a tried and tested (but not documented) setup
• ReplicationUsingGroove
• ReplicationUsingFolderShare
• ReplicationUsingFTP

Windows Shareware

CVS (SVN, etc...)

In the past I've also experimented with using CVS as a replication system, and that is actually much nicer to work with - since you gain offline read/write as well as distribution. These days using SVN (or probably SVK) would be much nicer. Despite the potential problems of conflicts, it works a lot better than you would expect. (Rather than replace the RCS store the CVS synchronisation operated side by side with the RCS synchronisation, side-stepping any need to change the TWiki codebase itself)

That 'TWikiGuest' contribution was from Michael Sparks, BTW, in case anyone was wondering (as I was).

My own experiences of replication using Clearcase Multisite may be of some relevance. Very powerful, peer-to-peer replication, but rather prone to going belly-up when you least want it to (usually involving a three-hour packet rollback on the morning of the release ).

I welcome Michael's opinion.
