PyCon DC 2003 Sprints

PyCon DC 2003 Sprints: Call for Participation http://www.python.org/cgi-bin/moinmoin/SprintPlan We are seeking coaches and participants for the sprint sessions preceding PyCon DC. A sprint is a two or three day focused development session, in which developers pair in a room and focus on building a particular subsystem. A sprint is organized with a coach leading the session. The coach sets the agenda, tracks activities, and keeps the development moving. The developers work in pairs using extreme programming's pair programming approach. The sprint approach works best when the first few hours are spent getting oriented -- presenting a tutorial for the development material, laying out the stories to tackle for the day, getting everyone a CVS checkout to work with. We need coaches to develop a sprint topic, lead the development effort, and help with the logistics of matching participants with sessions. In a successful sprint, the coach usually spends a lot of time helping others and little or no time doing development. What makes a good sprint topic? It must be possible to make real progress with just a day's effort. It would be good to make small enhancements to existing projects, finish off ongoing development on some project, or work on a new library that you'd like to contribute to the standard library. It probably doesn't make sense to sprint on a project that is brand new; you'd be better off sitting in a coffee shop talking. We're looking for topics that would hold the interest of 6-12 developers for a day or two. If you would like to coach a sprint, please send mail to jeremy(a)alum.mit.edu. We would like to finalize the sprint topics next week, so get in touch as soon as possible. We already have two sprint sessions planned. Chris Armstrong will be coaching a Twisted sprint, and Jim Fulton will be coaching a Zope sprint. People who want to participate in the sprints, but not coach, should make arrangements with a specific coach. The coaches will help me allocate the space fairly among the different topics. Space may be limited, so we would prefer to have people make plans to attend a specific sprint in advance. If you want to come, but don't know what session to attend at your name to the Wiki so that we can match you up with a sprint. The cost for attending the sprint sessions will be $25/day. That amount will cover the cost of the sprint rooms and electrical and network infrastructure. We don't expect to provide meals, but there is a cafeteria in the building.

POSKeyErrors
by Brian R Brinegar 14 Feb '03

14 Feb '03

We are running Zope 2.5.1 and ZEO 1. When someone does an Undo it doesn't seem to update all of the ZEO clients consistently. Some ZEO clients reflect the undo, others sometimes show an older version of the database and sometimes we get POSKeyErrors. Any idea what causes this? It's an old version of ZEO, is this a known bug? The traceback is below.

PCGI?
by Jim Fulton 14 Feb '03

14 Feb '03

I'm wondering how PCGI should be supported in Zope moving forward. We currently have: - A PCGI server in ZServer - A pcgi directory that contains: o A cgi program that is very thin and whos only job is to forward requests to an app server running pcgi o An unused PCGI "publisher", which would be used by a Python application server that wasn't running ZServer. o A debugging tool named MrCreosote. I don't know if anyone is using this. I'd like to continue supporting PCGI in ZServer as long as it is used. I'd like to omit the pcgi directory fron the Zope distribution and make it a separate distribution. Would anyone object to these changes for Zope 2.7?

How about making it a separately downloadable add-on like LocalFS, Squishdot, etc. etc. --Craeg > Jim Fulton wrote at 2003-2-13 11:30 -0500: > > I'm wondering how PCGI should be supported in Zope moving forward. > Do we still need it? > > I would prefer to drop it (to reduce complexity). > > > Dieter > > _______________________________________________ > Zope-Dev maillist - Zope-Dev(a)zope.org > http://mail.zope.org/mailman/listinfo/zope-dev > ** No cross posts or HTML encoding! ** > (Related lists - > http://mail.zope.org/mailman/listinfo/zope-announce > http://mail.zope.org/mailman/listinfo/zope ) >

Python core dump zope 2.6.1+CMF1.3
by R. David Murray 13 Feb '03

13 Feb '03

I haven't touched Z2 in a while. But I need a Plone site (I think). So I downloaded 2.6.1, CMF1.3, and Plone 1.0. Installed all on FreeBSD 4.7. Created a plone portal. Going to the plone site URL causes a python core dump. Created a plain CMF site. Going to the site URL causes a python core dump. Going to the /manage version of the same URL works fine, by the way. Others have seen this, so it should be easy for Concerned Parties to reproduce this. I have to run off to a meeting so I can't do any more deubgging on this tonight. NB: python 2.2.2 also core dumps under the same scenario. --RDM

Multiple author and reviewer roles in Zope CMF
by David Cain 13 Feb '03

13 Feb '03

I would like to apply Zope CMF to our organization which is made up of numerous departments. Each department has one or more managers (reviewers) and content providers. Also, some managers cross departments, as well as content providers. How can I create several Zope CMF roles (reviewer and author) for each department so that reviewers for that department will only see content created by authors in that department?

passing browserId value
by Mario Bianchi 12 Feb '03

12 Feb '03

Hi list, I want to embed the browserId value in every link/button/clickable-item of the p ages in my site, so that users get a sessioned access without using cookies. How can I manage this task without having to manually rewrite the code of the pa ges served by the site? Some pages are the dynamical output of a Zope product call, how can I intercept them, embed the browserId and then serve it to the client? It seems to me that embedding the browserId DYNAMICALLY is the only way to avoid statically re-write a lot of code (error-prone and time-wasting approach), the matter is how! I would prefer not to use JavaScript, only DTML or other Zopish/Pythonish resources. Thanks in advance, cheers, Mario. _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963

Accept-Charset hearders causing 500 internal server error.[correct but not lenient]
by Romain Slootmaekers 12 Feb '03

12 Feb '03

Hi, We have problems with the Accept-Charset headers that are sent to the zope server by some mobile phones: fi: 'Accept-Charset':'ISO-8859-1, US-ASCII, UTF-8; Q=0.8' These cause a 500 internal server error. (Error Value: invalid literal for float(): =0.8 ) I checked with the HTTP1.1 RFC26160 section 14.2 and the header seems valid, but in fact isn't: there is a space between the semi-colon and the Q char (which shouldn't be there acoording to the spec). So, in principle, this is not a zope server bug, but an inflexibility. I think the server should be a bit more lenient. a simple .strip() in the right place should do. Could you guys fix this? TIA, Sloot. BTW, for completeness, I included a quick test program is included below (causes a 500 on my zope 2.6.0) : #--------------------- program illustrating the behavior ----------- import httplib, urllib def sendHTTP(): """ """ headers = {'Accept': 'application/vnd.wap.wmlc, application/vnd.wap.wmlscriptc, application/vnd.wap.wbxml, image/vnd.wap.wbmp, image/gif, application/*, text/html, application/xhtml+xml, application/vnd.wap.wml+xml, text/css', 'Accept-Charset':'ISO-8859-1, US-ASCII, UTF-8; Q=0.8'}#, ISO-10646-UCS-2; Q=0.6' conn = httplib.HTTPConnection("127.0.0.1:8080") conn.request("GET", "/mobile/wap/games/",headers=headers) response = conn.getresponse() print response.status, response.reason data = response.read() print data conn.close() sendHTTP()
