Re: pyblosxom 3000

Hi all

I've sucessfully patched in the inputstream/outputstream stuff.

Before I go any further I wanted to ask you all a few questions 
regarding API changes for 1.2. Some of this is redundant with stuff I 
previously posted, sorry for that.

Here are the changes I'ld like to propose:

Application startup (pyblosxom.cgi):
p = PyBlosxom(config, environ) # environ becomes ._http
# static
p.runStaticRenderer(incremental)
# test
p.testInstallation()
# cgi
p.run()
response = p.getResponse()
response.sendHeaders(sys.stdout)
response.sendBody(sys.stdout)

The response stuff in the #cgi part is required since mod_python and 
twisted handle this part differently, hence p.run() should not write 
headers or data directly.


Outputstream (pyblosxom.py):
response = request.getResponse()
response.addHeader('Content-Type', 'text/plain')
response.write("Hello World")
response.writelines(["whatever", "you", "want"])


Renderer (base.py):
rewrite showHeaders to call addHeader on the response instead of writing 
to stdout.


Inputstream (pyblosxom.py):
infile = request.read()
infilepart = request.read(1024)
inline = request.readline()
inlines = request.readlines()


Form handling (pyblosxom.py):
form = request.getForm()

This allows a lazy approach for calling cgi.FieldStorage.
My problem with the current form handling is that the inputstream is 
consumed by cgi.FieldStorage, whether a form is actually used anywhere 
in the callback chain or not.

And when my poor plugin want's to read some xml which a client app has 
sent there's nothing left to read from.
I believe this may also solve the problem Richard Chamberlain described 
in his mail "xmlrpc_metaweblog.py problem" to the pyblosxom-users 
mailing list.

This can be made backwards compatible if necessary.


That's about it. It's actually allready coded. If you think that all 
sounds good I'll send in a patch.

Concerns? Ideas?

cheers
Steven
