tree and expand_all
by Petr Knapek 03 Mar '00

03 Mar '00

Hi all, I have a problem with expand_all variable in tree which should expand whole tree. When I post it (<A HREF="<dtml-var URL0>?expand_all=1">Expand</A>) it doesn't work. No change in tree rendering. On the other hand the collapse_all works as predicted. Is anything wrong what I do or is it a bug? I use Linux with Zope 2.1.4 Thanks, Petr -- Petr Knápek PVT.NET, e-mail: petr.knapek(a)pvt.net, tel:+420-5-41 558 394 PVT a.s. - pvt.net, Veveří 102, 659 10 Brno, Czech Republic

Batch processing... SOLVED
by Curtis Maloney 03 Mar '00

03 Mar '00

Again, greetings... So I kept looking at what I had, and some things just did NOT look right. So I fiddled. I wrangled. I bashed it with various bits of office equipment. And I got it to work! here is a cutdown of what i used: <dtml-in "somQueryHere" size=5 start=qs> <dtml-if sequence-start> <dtml-if previous-sequence> <tr><td colspan="2"><a href="past_orders?qs=<dtml-var previous-sequence-start-index>"> Previous <dtml-var previous-sequence-size> orders.</a></td> </tr> </dtml-if> </dtml-if> <tr><td>STUFF</td> <td>FROM</td> <td>ITERATED</td> <td>QUERY</td> <td>HERE</td> </tr> <dtml-if sequence-end> <dtml-if next-sequence> <tr><td colspan="5"><a href="past_orders?qs=<dtml-var next-sequence-start-index>"> Next <dtml-var next-sequence-size> orders.</a></td> </tr> </dtml-if> </dtml-if> </dtml-in> it's much simpler than the example in the DTML book (IMHO), and it would be faster in making only ONE call to whatever query it is you're using, not 3. I'm not sure who is in charge of the DTML reference manual, but if i get a moment i will be forwarding this code snippet on to them. -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Security flaw in Zope FTP server?
by jiva＠devware.com 03 Mar '00

03 Mar '00

I was running a security scanner (nessus) on my webserver tonight, and it came back with port 8021 having an ftp server which "closes the connection when USER, PASS, or HELP is given with a too long argument." It says "This is probably due to a buffer overflow" Is this a false positive? Or is this something to actually be concerned about? -- Isn't it nice that people who prefer Los Angeles to San Francisco live there? -- Herb Caen

Batch processing...

Green things... I am having problems with the dtml-in batch handling.. I've basically copied from the DTML guides example, but my previous and next links NEVER appear. I mean, sure. I am only getting the first 5 items in the list, as i should. But the links forward and back are not working. I can paste the code if you like, but it's really just replacing w36 with my sql query. -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Re: [Zope-dev] problems with TM.py

Additionally as >_registered is defined as a class variable it is shared among threads and >therefore one thread can interfere with the state of another. I would like to understand the source of your problem, too. However, I think there is a misunderstanding here. In TM.py, _registered is a class data attribute, which is typically a trick for "initializing" Python instance data attribute. That is, unless you explicitly do something like TM._register = 1 the class variable would never change. That is, TM._register is always None. Always always. So there should not be any problem in thread interference. If x is an instance of TM (or an instance that has TM as an interface, in the case of multiple inheritance), if you look at the dictionary of x, i.e: x.__dict__ , you will see that initially x does not have an attribute _register in its own dictionary. However, x._register is a valid reference, because it borrows from the class attribute. The statement: print x._register would print out 'None'. As soon as you assign a value to x._register = 1 you create an attribute in the dictionary of x. That is, a new item is added into x.__dict__ , which is totatally independent of TM._register. So TM._register remains as None. >I have changed all references to _registered in TM.py to _v_registered and >my problem (creating new versions for every call to FSSession) is solved, >but I am not sure what other classes use TM.py. Also I am thinking of >changing _v_registered to an instance attribute instead of a class >attribute. Any thoughts?? Is it a bug of TM.py I'd like to take a look into it, too. But first I'll have to learn what the flags _v_registered and _register mean. :( I don't even understand what is a "transaction" in the sense used by the transaction manager. If I understand correctly, the definition of "transaction" that you would like to use is one single HTTP transaction, which lasts from the beginning of a foreign HTTP client request till the end of Zope sending out the reply. The question is: is this the same definition of "transaction" as used by the transaction manager? Why would anything be stored in ZODB?!? The HTTP "transaction" should not have anything to do with ZODB database "transaction". The "versions" that are stored in ZODB, are they FSSESSION objects? I'd like to look into all this. :) regards, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Anyone else notice this problem? Hmm. ZClass products aren't automagically imported; when exported, turn into zexp files, either on the client machine somewhere or in the server's $ZOPE_HOME/var directory. To install them on another server, on must: * copy the *.zexp file into the new server's $ZOPE_HOME/import directory * import the *.zexp file into the "Control Panel | Products" folder. You don't have to restart the new server, either, unlike "normal" Python products. Unless somebody borrowed Guido's time machine and retrofitted Butch Landigan's ZPack proposal, that is?
