why I don't use popen2 any more
by Dennis Nichols 21 Dec '00

21 Dec '00

In the for what it's worth department... Using Linux (RH 6.2), Zope 2.2.2, Python 1.5.2 I wanted to run a unix command from my External Method that I wrote using Python. Digging around in Zope archives and other sources, I came up with a method that worked, of which this is a fragment: import popen2 (r, w) = popen2.popen2('somecommand') w.write(commandinput) w.close() s = r.read() r.close() However, this had the nasty side effect of leaving <defunct> processes around. I discovered one instance on the web of someone having this same problem using Python but not Zope-related. No solution was given. I *think* the really bad thing about these processes (called zombies?) is that they may have certain resources, such as files, held open. And they are said to stay around until the process that created them dies itself. The fix seems to be easier than the original solution. Replace all of the above with import commands s = commands.getoutput('echo ' + commandinput + ' | somecommand') Presto, no more defunct processes. Hopefully a more stable Zope. Keen observers will note the security risk if commandinput contains arbitrary input from users. Wasn't true for me but it might be for you. A curiosity: the description in Python Essential Reference says getoutput uses os.popen2() to execute the command, but I was too lazy^H^H^H^H busy to investigate further. -- Dennis Nichols nichols(a)tradingconnections.com

Re: [Zope] How to make two racks work under one specialist?
by Dirksen 21 Dec '00

21 Dec '00

Hi Steve, Deliverables has objects. The call to existent objects are successful. It's the call to the inexistent objects that doesn't turn out expectedly. But the first thing is whether my script is correct. Do you thing so? And any other way to test this kind of situation, i.e. passing processing when failure. And what's the best way to debug a skinscript. So far I can only guess when it comes to debug a skinscript. And what's wrong with WITH Deliverables.getItem(self.id) COMPUTE name, dueDate, description, todoIDs I cooked this up according to the SkinScriptSyntax wiki, but it doesn't work, complaining not_found when calling the existent objects. A change like this fixes the problem: WITH Deliverables.getItem(self.id) COMPUTE name=name, dueDate=dueDate, description=description, todoIDs=todoIDs What's wrong with my assingmentornamelist?

no hasattr() in Python Script?
by System Administration 20 Dec '00

20 Dec '00

I'm trying to call a Python Script from a DTML method using <dtml-var "units.statistics.edit(this())"> in order to edit some numeric properties of an object. I have "self" as the parameter list. If I set the object's property "foo" to "123" and make edit return(self.foo) I get "123". That's good. I'd like to be able to test if "foo" is already set, though. It seems obvious that I should be using hasattr(), but if I make edit if hasattr(self, 'foo'): return('set') else: return('not set') I get a NameError for "hasattr". I tried making it if _.hasattr(self, 'foo'): return('set') else: return('not set') and that doesn't generate an error, but it returns "not set". Any pointers? I'm hoping I'm missing something simple here. BTW, I'm using today's CVS (with kludges to make LoginManager work). Thank you. --kyler

[BUG] Background processes interfere with Zope's HTTP responses
by Dieter Maurer 20 Dec '00

20 Dec '00

Today was again a hard Zope day. Did you ever hear, that usually (i.e. if you do not do special things) Zope renders a complete page before it starts sending the result back to the client. This implies that you should never see only half of a page. I heard it and I saw the code that does it. Therefore, I was convinced that this were really the case. Then our client phoned: He visits a page that allows him to generate a newsletter. When he presses the "generate newsletter button", a result page is build that tells him that the newsletter is being generated and send is a few minutes. He reported, that this response page is build only half, then stops, to be completed only half a minute later, at the same time when the newsletter arrives. The effect is reproducible. If newsletter generation takes longer, he must wait longer for the page to complete. He is convinced that we generate the newsletter synchronously and let him wait until the generation is complete. And he is angry. I know, that the newsletter is generated in a background process, started in an external method with: os.system("gen_newsletter &") I try to reproduce the behaviour in our test environment and fail. I do not have to wait, until the newsletter generation finished. Then, I use the official service URL and see, I observe the same behaviour. The difference: in the test environment, the browser connects directly to ZServer; with the official URL, it connects via a proxy. Puzzling! What happened? The background process inherits Zope's open file descriptors. Among them are all currently open HTTP request sockets. The process keeps these sockets open until it finishes. There are two HTTP modes: 1. single request mode a new TCP connection is created for each HTTP request, the request is completed, when the TCP connection is closed. 2. multi request mode several requests share a single TCP connection. The "Content-Length" HTTP header allows client and server to determine the request boundaries. That means: when a client uses the multi request mode, everything is fine. Clients, however, that use the single request mode wait until their connection is closed and can observe serious delays. These delays may be very difficult to explain, as the background process not only delays its own request but may delay arbitrary other requests that happen to be served at the same time. How to fix the problem: There should be a (file) control "CloseOnExec", that tells Unix to automatically close the file like object upon an exec. ZServer should probably use it on each of its sockets. I can not see a serious application that should have direct access to ZServer's HTTP request socket. I will soon file a bug report into the Collector. Dieter

LoginManager+BasicCookieAuthentication
by Robert Senger 20 Dec '00

20 Dec '00

Hi all, does anybody know how I can get rid off this ugly 'traceback' in the loginForm object Zope displays when using LoginManager and BasicCookieAuthentication? I want to customize the look of the loginForm to fit into the design of the rest of my pages. Thanks! -- Dipl.-Phys.
