Hallo alan,
Not exactly. It's a combination of server load (long requests) and other objects that are read. I think that the transaction management of Zope have problems with request on objects that take a long time. So if a request takes too much time and another request want to access another object than it might crash.
ar> have you tried to use the logging features of ZOPE? z2.py ar> STUPID_FILE_LOGGER=var/Zope.log ar> I got this information from ar> http://www.zope.org/Members/michel/Projects/Interfaces/LOGGING.txt/ I have had a look to it. It's meant for "If you want your own Zope extensions to use logging:", doesn't it ? I needed information about the logged in user name to be logged, that I can see, what user requested which pages. ar> I believe the STUPID_FILE_LOGGER will give you more information on this. I ar> should have brought it up earlier. and we should have been discussing this ar> on the ZOPE mailing list so we could have this archived. those conflict ar> competing writes usually have path associated with it. are all of these ar> occuring in the same location in the ZODB? No. They are different. I configured STUPID_FILE_LOGGER in start script and wait until I get some output. I don't think that it will log something until I write my own logging class like the example on the webpage. ar> yikes, this is very bad. Andy McKay has helped port ActiveStates website to ar> ZOPE and I wonder if they are experience the same problems. I don't think so. They have no really dynamic system I think. ar> there is no doubt that ZOPE has more experience and is favored to run on ar> *nix ,from what I understand. You are right. The internal server have to be in the LAN of the company. And the company have only Windows :-( The external Server is provided by our company and is of course a linux :-) ar> the big files should be served from apache and not ZOPE. that is the lesson ar> to be learned I believe. Sorry that is not really possible. I need complex authorization on that documents (Roles, IPs, internal/external Server Request, Usernames, ...). ar> You say the code is 11500 lines long. You are using German characters I ar> assume, I wonder if this is causing any problem? I don't thinnk so. I have some german characters in it, because sometimes I need them; e.g. for HTML quoting, some strings, filename convert. The Users sometimes loads files in the system with german special chars and I convert them to really nive chars. ar> How experience with Python are you? I see you had setName getName, in python ar> you usually directly set/get attributes with instance.property=value and ar> value=instance.property, overloading __setattr__ and __getattr__ if you ar> wanted to do a tiny more than set/get values as well. I'm needing some 'intelligent' methods. Less methods really only return the value. Most of them do type castings, return value depending on parameters, ... . I started working with Python 2 years ago. I wrote some C modules for my needs, where Python is too slow. Actually I'm on my way to release a Python XML module that have it's own Plugin API that you can use real xml parser in the backend of my module (I'm testing with libxml). This is a nice project, but I have no time to finish this module, because of my job :-( I learned Python, Zope, XML and other technologies very fast, because the first project have to be done in very short term. And a friend said that you can realise such projects very fast with python and zope. So I learned it in about 2-3 weeks. I'm developing programs since 1982 on different computers and programming languages. ar> ~runyaga ciao. Stefan
