DA Question...
by Sascha Matzke 31 Aug '99

31 Aug '99

Hello, I'm planning to write a product which depends on RDBMS access. My only concern are those thread-issues... Could a connectionpool (an object that holds 10 or more open connections) be a way around this ?

RE: [Zope-dev] Zope and Com : CoInitialize done on each thread by Zserver?

> Until this issue is resolved, where would you suggest that I place my > call to CoInitializeEX()? > > It has to be called only once, when a thread is created. (I'm CC'ing this to the list, since this trick may be useful to others...) If it were me, I'd try _real_ hard to not have to hack up the medusa code (which is where the actual threads get created), and try to find a sneaky way to get the job done from within your product. Here's one way you could do it (not very pretty, but it should work without requiring hacks to Zope code): (in the .py file of your product) _tmap_={} def ensure_init(): # waaa - make sure CoInitialize has been # called for this thread... id=thread.get_ident() if _tmap_.get(id, None) is not None: # this thread has been done already! return # otherwise we need to do it... win32com.CoInitializeEx(...) _tmap_[id]=1 return ...now you should be able to stick an ensure_init() call into your code before you start messing with COM, and the Right Thing ought to happen. It adds a little overhead, but in most cases you could probably streamline this further depending on how your code looks. Hope this helps!

Persistence
by Paul Prescod 30 Aug '99

30 Aug '99

I think that this: http://www.zope.org/Documentation/Reference/ObjectPublishingIntro is out of date, right? BoboPOS no longer has "PickleDictionary". It would be great if this document could be updated with a message: "this info is a little out of date. Please see blah." Zope really doesn't like what I came up with through hacking around: def doit( state="Texas", city="Dallas"): connection = Globals.DB.open() states=[] connection.root()["abc"]="def" return "foo" Paul Prescod

in 'singleton'
by Robin Becker 30 Aug '99

30 Aug '99

it would be really useful to generalise <dtml-in var> to allow for the case when the variable is a singleton. I know I can write testing code for this, but it's a real pain to find that multiple selections change type when only one item is selected. -- Robin Becker

That will benefit the user. I would like to suggest puting a cookie to remember the user's last visit time. Compare that time with the document's last modify time. and display a new to you label next to the document. Rgs, Kent Sin

Hi! Dumb question: Did anyone try to server more than one ZOPE site from 1 ZServer? (I mean, this will be needed for Name-based virtual hosts.)
