[Zope] migration from 2.9.1 to 2.9.4
I am having some problems migrating from Zope 2.9.1 to Zope 2.9.4 on my Windows 2003 based Zope setup. Installation of 2.9.4 goes normally -- both servers (2.9.1 and 2.9.4) seem to be running happily (on different ports). My first strategy in migration was to copy the data.fs from 2.9.1 to 2.9.4. That seems to fail as certain "directories" when viewing is attempted from the 2.9.4 ZMI exhibit the following error: Traceback (innermost last): Module ZPublisher.Publish, line 106, in publish Module ZPublisher.BaseRequest, line 275, in traverse Module ZPublisher.BeforeTraverse, line 108, in __call__ Module logging, line 999, in error TypeError: _log() got an unexpected keyword argument 'error' My next strategy was to export to .zexp the critical material from 2.9.1 and import into 2.9.4. All appears to go well -- but attempts to access the imported material from the 2.9.4 ZMI fails with the same message. Any idea what is going on here? Any other strategies for migrating that anyone can think of or things to look at? ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Errors with OOBTree may be connected with session machinery. We had such problems under high load and ZEO. Changing session_resolution_seconds value in zope.conf to 300 solved the problem. You may try this but, if I remember correctly, it will cause that your sessions timeout may be 300 secs longer and/or shorter. You may try other values.

In this case it just pegs the cpu running the python zope process at near 100%. Any errors in event log or Zope just doesn't answer for a long time? If the latter thing then there is a DeadlockDebugger that shows what is Zope doing, even when it is not responsible, but I'm afraid that it won't work under Windows, but I've never tried. I will have a look to see if it provides any information. > What does this message mean -- should I be worried about it? As far as you see only INFO it is nothing bad, but ERROR that means conflict error was unresolved is visible to the user, although hitting 'Refresh' usually is enough. It seems that just having the error in info is not a problem but what I am seeing is that often after an "unresolved" instance my problem happens. There you may find some informations (but this is based on zope 2.7): http://www.plope.com/Members/dunny/conflicts/view I will look there to see if there is anything that seems relavent. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] pool_size
I am having a problem with zope 2.9.4 occasionally pegging the CPU and thereafter being unusable -- there are some indications in the event log that this is related to "pool_size" being too small. Lacking any other strategy to determine the cause of the problem, I am considering experimenting increasing "pool_size" to see what effect it has. A search returns some inprecise information on how to do this. My understanding is that this can be modified in the zope.conf for the instance.

[Zope] Date utility for Zope (V2)
I am looking for a standard way (from a python script in Zope) to define and manipulate time intervals for periodic events. I need to define things like every weekday at 8 am, the 2nd day of every month at 8am, every weekday at 8am, 10am and 3pm in addition to easy things like everyday at 1pm. Does such a standard exist - perhaps with a library to manage the conversion to real times?

Re: [Zope] Date utility for Zope (V2)
I have recurring events that I want to schedule (the events are sending email, Twitter DMs and Facebook messages -- at least those are the possible ones that I have identified so far). I need some flexible way to both specify the intervals and interpret the intervals so that the next event in a sequence can be specified in real time terms and scheduled. The event schedule at least in plain English could be something like " every weekday at 8:45", "every Monday at 9:00 and 1:00", "every day at 2:00", "the first of every month at 9:00", "every other Monday". I realize that I may have to settle for something that is not quite as flexible as I imagine and at least for now I am just trying to see if someone else has solved this problem or one similar and has something I can use as a base. I do have a way to trigger and execute the events at specific times.

Re: [Zope] Date utility for Zope (V2)
I had a look at tutorials to create products for Zope2 and at first glance they are beyond by pay grade. Maybe I will look at them more closely to see if I might have been hasty but likely it will be easier for me and take less time just to write what I need in script and forgo the "I would like to do stuff".

[Zope] "double opt-in" or "opt-in with confirmation".
I am looking for a strategy or samples (or even just a hint as to the best process) to create an email opt-in strategy in Zope.

Based on what I am seeing -- some sort of MD5(not totally sure what that means but I understand there are Python supplied functions to generate it) hash of a combination of the email address and date/time stored and then sent to the user should guarantee that it is unique, can't be auto generated by some bot and should allow verification on http access using the hash in the url?

[Zope] mod_rewrite and IIS7

I do have access to the server (Win2000 in my case) so I can pretty well do anything I want.
It comes back now -- I did something like that but then called it through a gateway Python script that allowed me to turn off all logging in one spot easily (by modifying the script) in case I wanted to leave the debug statements there temporarily and not incur the expense of a huge log file.

I figured out what the problem was -- it seems the ASP404 script depends on REQUEST_METHOD set in the request header to decide what mode to open WinHTTP in. On Win2000 the REQUEST_METHOD is set to the method of the request (GET/POST). On 2003 the method is always set to GET regardless of the original method.
The only solution I could find was to use Request.totalbytes > 0 as a check to set the WinHTTP open mode. Something like:
openmode = Request.ServerVariables("REQUEST_METHOD")if Request.totalBytes > 0 then openmode ="POST"end ifzopeServer.Open openmode, zopeRequest, False
Somehow it seems like not a very satisfying solution but it serves my purpose at this point.

[Zope] Cache headers
I am trying to ensure that zope delivered content (Zope 2.7 at this point) is upstream cacheable regardless of whether the users delivered to are authenticated or not(currently my site is fronted by Cookie Crumbler based login/authentication).

[Zope] Upgrading to Zope 2.9.1
I am in the process of testing an upgrade from a Zope 2.8.4 system to a Zope 2.9.1 system. The process I used: 1) Install 2.9.1 on a Win2003 system (it happens to be the same one that the 2.8.4 system is running but I changed the config so the ports don't conflict). The installation is successful 2) Copy the Product directory from my functioning 2.8.4 system instance to the 2.9.1 instance 3) copy the ZODB from the functioning 2.8.4 system to the 2.9.1 system All appears to go well -- the 2.9.1 system appears to be running everything from the 2.8.4 system correctly. A deeper check though shows that a few Python scripts in the ZODB (this in a system that has 20 or 30 scripts) fail. Examining the scripts indicates an error at line 3 -- but no such error can be found, however saving the script with no changes eliminates the error and also causes the script to now function. After finding and correcting these scripts everything seems to be working well. Any idea what happened during the upgrade to cause this strange behaviour and how can I avoid it? I will have to go through a similar upgrade at a customer's site and would like to avoid hand checking every script if I can avoid it. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Re: Windows Server 2003, II6 and ASP404 vs form posts
For anyone else who might search the list in the future: Microsoft has confirmed that ASP error handlers in current versions of IIS 6 do not, can not, and will not -- no matter what the security settings -- get at POST data. There's a discussion of the changes at: I think that is not 100% true-- I am not sure where the difference lies -- but as we discussed I am using ASP404 on Windows 2003 (at http://www.coursesbywire.com) with form Posting functioning. The only issue (that I ran up against and had to solve) is that the method used in ASP404 to determine whether the original request was a POST or a GET no longer works on Win2003 (as it did on Win2000) -- it is necessary to introduce a kludge in the ASP code. http://blogs.msdn.com/david.wang/archive/2005/11/29/Child_URL_Execution_and_SSI_exec.aspx The author confirmed that the changes also affect custom error handlers. So, the days of serving Zope pages on IIS via the 404handler.asp approach are pretty much over. Not quite -- but maybe numbered. I agree though that starting out now using it when it was not previously in use might be a bad plan. I am not totally sure what is causing your problem but on my (fully patched Win2003)server the Post data is available. I had a look at Enfold's Proxy when I this issue first came up for me but found that it did not solve my problem (though it could be that I just didn't understand something about it). In my case putting Apache in front did not seem a reasonable solution either as I am running IIS on the box and needed it to stay. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
