ZPublisher events before streaming a response
by Martin Aspeli 21 Mar '10

21 Mar '10

Hi, In some cases (e.g. large OFS.File/Image responses), Zope 2 will use response.write() to stream the response. We have events that fire before and after a "regular" response is returned, but none that allow us to set headers (caching headers, in this case) before such a streaming response is calculated. The normal events fire too late. We'd therefore like to add a new event in the HTTPResponse class (in ZServer, though I think it makes sense to add to the ZPublisher base class version as well). It'd hook in something like this: if not self._wrote: # new event code site = getSite() request = getattr(site, 'REQUEST', None) notify(PubBeforeStreaming(request)) # continue as before... (I couldn't find a better way to get hold of the request from a method in the response, without adding a dependency on five.globalrequest, which I assume is not desirable). Any objections? We need this in Zope 2.12, though I'll obviously merge to trunk, too. Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.

Agenda for today's IRC meeting (3pm UTC on #zope)
by Christian Theune 18 Mar '10

18 Mar '10

Hi everyone, today's the third weekly meeting and here's the reminder including the proposed agenda. Time and place, building on previous weeks, are 3pm UTC at #zope at freenode. That's about 90 minutes from now. If you'd like to review last week's summary, please check here: https://mail.zope.org/pipermail/zope-dev/attachments/20100310/6e95116e/atta… Agenda ------ With the experience from last week (we only barely managed to go through a single issue) I'll have the agenda a little more reduced. If we run out of topics, we can move over to stuff from the horizon. - Test runners / nightly builds - Short status report (Volunteer, access to Windows build environment) - Towards a ZTK release - What is needed for a release? - Who's the release manager? - Can we ensure building Windows binaries? - Wrap-up (5 minutes) Horizon ------- These items are currently tracked on the horizon. We won't discuss them at this meeting, but we'll get to them at some point: - Test runners / nightly builds - Volunteer for coordinating automated builds - Towards a list of projects/platforms/etc. we want guaranteed builds for - Automatic binary egg builds for Windows - Access to Windows (2003) build machines for developers (Baiju M.) - Bug tracking / working on bugs regularly - How do we deal with proposed API changes and Python 3 compatibility? (Lennart Regebro) - Pondering *some* (re-)structuring of the ZTK to allow for better maintenance/release management/communication/marketing. (Chris McDonough) Hope to see you in about 90 minutes, Christian -- Christian Theune · ct(a)gocept.com gocept gmbh & co. kg · forsterstraße 29 · 06112 halle (saale) · germany http://gocept.com · tel +49 345 1229889 0 · fax +49 345 1229889 1 Zope and Plone consulting and development

zope.component.zcml and global registry
by Fabio Tranchitella 15 Mar '10

15 Mar '10

Hi folks, the ZCML directives in zope.component register components using the utility method handler, which looks like: def handler(methodName, *args, **kwargs): method = getattr(zope.component.getGlobalSiteManager(), methodName) In our company-specific framework (which is far far from zope3, and only uses the bicycle repair kit), we use different registries per application, similarly to repoze.bfg. Everything works, included code which relies on the zope.component's API, thanks to the hooks on getSiteManager. Those ZCML directives use the getGlobalSiteManager though, which is not hookable and thus we had to reimplement the ZCML directives we need to call getSiteManager instead of getGlobalSiteManager. By default, getSiteManager returns the global registry, so I don't see any obvious reason why the ZCML directives make use of getGlobalSiteManager. repoze.bfg, for example, reimplemented the ZCML directives as we did, but I'd love to be able to use the implementation from zope.component. Any idea? Would you kill me if I propose to change the registration handler to use getSiteManager instead? :) Thanks, Fabio
