Hi,
Is there an existing protocol that can provide the following?
- Accept stream binary data FROM a client (e.g. very large file
transfer)
- Receive data IN ORDER (i.e. stream. not out of order random packets)
I want to stream FROM a client to the protocol server and have the
server process th
Hi,
I have an application that uses twisted.enterprise.adbapi for
accessing sqlite database.
Recently I had to replace sqlite3 shipped with python 2.5 with latest
version of pysqlite2. This was for taking advantage of newer fixes in
pysqlite2.
I thought it would be worthwhile to support both.

Hi Darren:
Why not use TCP? You can send the length of the file at the beginning so
you know how many bytes to listen for.
TCP guarantees delivery and ordering.

Hey Mark,
Yeah, that's what I want, but in the 'twisted' way. I can write
socket servers, etc. But didn't notice a good example of how to do this
in Twisted (sparing me the socket programming), until I found this old
message[1] with the classes I think might work.

Good day:
I've been having fun with Twisted. I have my application running fine, with
multiple server and client connections using Telnet. :-)
However, users always want something. I need to send some unique
configuration information to each connection. The connections are made
using connectT
Hi:
Aren't you adding two readers? One is added in the __init__ method of
inputFile, the other in the test code.
I'm also a newbie so maybe I'm equally confused...

Thanks. I had actually already found your page and you're right, it does
seem to be the best resource out there. Since your email I've had a second
look at it, as initially I wasn't sure how to use the example to return a
web resource (handler with render_GET etc) in place of the file you
returned.

I don't think so. I believe the reactor is actually added during the
import. (I learned this as I discovered that reactors can't be
restarted, which means you have to manually create a new one as a
fixture for simple unittest work.)
I looked through the code and there's a call in the reactor

If you create two instances of your ClusterClientFactory, each with a
unique string, you should be fine. Requires only a small modification:
factory = ClusterClientFactory()
factory.maxDelay = 120 # two minutes

Hi Rich:
Try removing the "reactor.addReader(self)" call from "__init__" and see what
happens. That call is made when "r" is created in
r = inputFile('/etc/group')
and immediately after that you are calling
reactor.addReader(r)
So, you are calling reactor.addReader() twice on the same in

Haha, resolved now. Previously my setup wasn't sensitive to a missing
trailing slash on my PUT and POSTs, but now it is. I don't know why, but at
least it's solvable.
Thanks for the help

Doh. You're right about the double registration. Thanks. But that
doesn't change my problem.
The reactor still complains about the busted descriptor after removing
the reader and reseting my descriptor to -1.

Thanks, Arjan. Of course, factories are breeding like rabbits, but that was
the obvious solution! :-) I wish I had thought of it.
You saved me several MORE hours...I've spend all day on this.
(It's snowing and work was CLOSED! Yeehah!)

Thanks for that explanation David. Makes sense!
