After close to a month of development, Sahi V2 20080831 has been released today. (http://sahi.co.in/w/)
This release uses Rhino as the scripting engine, thus moving most of the script execution to the proxy. This should go a long way in simplifying Sahi scripts. Scripts now execute on the proxy, and only stuff that needs to execute on the browser is sent to the browser. Thus scheduler functions are sent to the browser for execution. One change which has come in is that custom functions which may have been added for identification of browser elements, now need to be wrapped in a <browser></browser> tag so that they are also sent to the browser.
This build also has some important changes to the SocketPool which will fix issues related to too many sockets being used and errors due to BindExceptions. Suite execution has been changed such that even if the browser crashes, the suite will continue with the next script and thus not hold up a build. DB methods now close connections properly.
There will still be a few rough edges and I hope users will report bugs so that they are easily fixed. Meanwhile, help spread the message through your blogs or email forums.

Sahi - Latest developments
Copy of post on forum: http://sahi.co.in/forums/viewtopic.php?id=261
I had not been active on the Sahi forums (http://sahi.co.in/forums) for sometime. Thanks a ton to StringyLow, tinchie8, lepierrot, pankaj.nith and others for keeping this forum active, and replying to posts.
Meanwhile I have been working on a version of Sahi which attacks one of the basic problems with Sahi.
Scopes of variables, scheduler and normal functions and the the way steps are queued and executed and the way their integrity needs to be maintained across page loads.
The problem had been that the scripts (after parsing) were executed on the browser itself, and when a page unloads, the state of the script's execution needed to be persisted on the proxy and then resurarected when the next page loaded. While this allowed the ease of using javascript for scripting, when scripts became bigger, the browsers and the proxy had to do a lot more persisting and resurrecting.
As the logical next step, I wanted to move this script execution to the proxy. I now use Rhino, an excellent javascript engine, to execute the scripts on the proxy. Only steps that need to be executed on the browser are sent to the browser. Javascript can still be used for Sahi scripting. Even though the script still is parsed, it is much simpler to understand script execution than it was before. Rhino also comes with a debugger which can prove useful to Sahi script debugging.
The version is slated to be released soon. I am looking for volunteers to test and give me feedback about the new version. If you have existing scripts, the scripts may need to be modified a little to make it work with the new version.
If you are interested, please post back or email me at narayan at sahi.co.in.
