Hello everyone Back in the summer I did a small demo http://217.147.83.36:9000/history::171=170 that allowed tracking contributions. It was quite slow and UTF-8 incompatible. So I'm pleased to announce that after some optimization and rewriting it in C I've managed to implement UTF-8 support and substantially increase performance. At the moment it is several times faster than current wikidiff2 extension (C++ version) and has peak throughput of around 3 mb/s. You can take a look at live demo. Sample blamemap: http://217.147.83.36:9001/wiki/Freebsd?trackchanges=blamemap&oldid=1524 Can track even a single character change: http://217.147.83.36:9001/wiki/Freebsd?trackchanges=diff1&oldid=1516 Handles text swap: http://217.147.83.36:9001/wiki/Freebsd?trackchanges=diff2&oldid=1513 I've plugged it into mediawiki code so at the moment every article and talk page is having credits section and corresponding blamemap. At the moment in order to use this you'll have to have root access to the server and some changes to the mainline code and database will be needed. If you're interested in testing this extension drop me a line. Best regards Roman
