TCPWatch... and closing sockets..
by Steve Spicklemire 26 Jan '01

26 Jan '01

I'm going to try to make a long story short... and the story isn't even over... but I'm getting close. One of our clients is a 'multimedia' company and we're working with a group there that consists mostly of artists and designers who use tools like photoshop and macromedia director. They came to us recently with a project for which they were *going* to use Macromedia Multiuser Server but the complexity of their application is significant.. long story short... I've sold them on the concept of using Zope as the 'media/personality server' for this application. They will use Director (which can post stuff to an URL and can also parse XML). So.. I'm building a framework that permits them to use their favorite tools, but I get to use *my* favorite tool too. ;-) The problem: Director is not a browser. There is no 'view source'. But (I think to myself) this is a great chance to use tcpwatch, which I've never used before. It's a little tricky since my favorite client machine is a Macintosh, and well.. lets just say that Tkinter for the mac is not perfect... not to mention there is no thread module.. but I do have a workaround that's useful (since I run Zope on a FreeBSD server, I just use tcpwatch on FreeBSD and either MI/X, or VirtualPC with Linux for my X server.. ). I noticed however that when I did a 'POST' the URL encoded arguments were lost. I found that the proxy_receiver handle_close method was never called.. so that anything in a 'last line' that didn't end in '\n' was lost. I added the following patch that shows this... but why is handle_close not called? I can only guess that the socket is not being properly closed somehow. I use lib/python/ZPublisher/Client.py to test calls to Zope and it works fine, but the asyncore/asynchat stuff never calls handle_close for proxy_receiver. Anyway... here's the patch: Comments welcome! *** ./tcpwatch_orig.py Sat Jan 20 16:55:43 2001 --- ./tcpwatch.py Sun Jan 21 16:52:11 2001 *************** *** 130,135 **** --- 130,137 ---- pos = pos + 1 else: # Last line, may be incomplete. + line = "Partial line? " + data[oldpos:] + '\r\n' + self.watch_output(line, byClient) return data[oldpos:] def cleanupRefs(self): take care, -steve

Minor oddity in beta 3
by Michael W. Homyack 26 Jan '01

26 Jan '01

One oddity I just noticed in the beta 3... if you have no folders created in the root, then the left-hand navigation pane doesn't show the Control_Panel, Quickstart, or acl_users folder. Once you add a folder, then all three of those objects, as well as the new folder, appear in the left-hand pane. If you then delete the folder, and refresh the browser, everything in the left-hand pane disappears again (leaving only the root folder at the top). Not a biggie, but a little odd. -- -- Michael W.

Unique ID generation
by Tim Moore 26 Jan '01

26 Jan '01

I'm writing a simple ZClass (and a second ZClass which contains the first) and I would like the constructor for this class to be able to auto-generate unique IDs for the instances rather than making the owner choose one. What I've tried isn't working, but I don't really know what I'm doing here...I figure this must be a fairly common problem, so what is the best way to handle it? The ID needs only be unique within its container object (i.e., doesn't have to be globally unique). I have full control over the container class, so solutions involving setting properties on that class are OK. TIA, -- Tim Moore

You can't find it because it doesn't exist :-) The datetime stamps are part of the PTK membership system and were left in that tutorial rather thoughtlessly. I've been trying to make them work lately and having a bit of trouble getting Postgresql and Zope to agree on timestamp formats... The current PTK updates them in the DTML method "logged_in", which is the action for the PTK DTML method "login_form" (it may also update them elsewhere). Dan Pierson

RE: [Zope] How to prevent the user from going

Netscape and Mozilla create make new HTTP requests when a user asks to view source or print. This drives me nuts. I want to see source of the page I'm looking at. If there are any Moz or NS people on the list, please enlighten us to the reasoning behind this behavior.

Login Manager
by Nick McDowell 25 Jan '01

25 Jan '01

Hi, I have installed Login Manager utilizing skinscripts as per Dan Pierson's article @ http://www.zope.org/Members/dlpierson/sqlLogin and everything works fine. I would love to customize it to tailor my needs and was wondering if anyone new of in-depth documentation detailing LoginManager. For example, I can't find the code that is inserting the datetime stamps into the database table "member_statistics". I think it must be in the Login Manager product and have been code trawling with no success. Cheers Nick

25 Jan '01

1a) <dtml-var id> is one way of writing it. 2a) <dtml-var "'text %s text'%id"> is another way of writing it 1b) <dtml-var id url_quote> is a second way of writing it 2b) ????? How do I do this one?? I have tried this, but that didn't work: <dtml-var "'text %s text'%id.url_quote()"> , but that didn't work either. What's the syntax? Anybody? Cheers, Peter
