Webware for Python

I use a call to self.response().flush() on a couple of long running transactions.  With the WSGI adapter on 1.1.b1 the transaction runs to completion, but nothing is transferred until the transaction completes.

I haven't tested this with other adapters.  Anyone else notice this?

Anyone else notice this? Just tested it with mod_webkit, mod_scgi and mod_wsgi and it worked nicely with all of them. Are you sure you're using the adapter? It does not work with the built-in webserver. Also, some Firefox plugins tend to pile up response data. Did you test with different browsers? There have been some changes to the WSGI adapter after 1.1b1, you can try with the current version (but it should also work with 1.1b1): http://svn.webwareforpython.org/Webware/trunk/WebKit/Adapters/WSGIAdapter.py -- Christoph

The problem was that Apache now comes with mod_deflate on by default and mod_deflate waits for and compresses the entire transaction's output before sending it on. For the benefit of anyone else who is using flush on a few long running transactions, mod_deflate can be turned off for a single servlet by adding a line to the apache conf: SetEnvIf Request_URI ^/webkit/MyXaction no-gzip=1 Thanks for all your help on the Webware enhancements Christoph!

I've addded this and hints about other possbile to the flush() docstring now. -- Christoph
