[Zope-dev] How to publish Zope2 products on PyPI
During our latest discussion to put my most important Zope2 products into a public repository, I have promissed to publish them on PyPI instead. Yesterday, I started work to fulfill this promiss and carefully read the PyPI related documentation -- to find out, that it is not easy to publish Zope2 products. As the name suggests, PyPI is for Python packages. And Zope2 products rightfully are no Python packages: When a Zope instance starts, it does potentially expensive things for its products. I have tiny Zope instances with a few inexpensive products that start within a few seconds. And I have huge Zope instances with lots of products which parse huge XML files or have large message catalogs and take half to one minute to start. Definitely, I do not want that all my Zope instances use the same products installed via setuptools somewhere under the central site-packages. My current ideas towards a solution: We define a package prefix for Zope2 products, e.g. zope2.products. Zope2 products are published to PyPI as prefix.productname. We extend the Zope2 configuration with an option additional-products which lists the products used by the instance that are not at a standard place -- such as those installed by setuptools -- Dieter ___ Zope-Dev maillist - Zope-Dev@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 )

robert rottermann wrote at 2007-9-21 09:11 +0200: does the installation of ZopeProfiler have a noticable performance impact when it is disabled? No. ZopeProfiler monkey patches ZPublisher.publish_module with the following function: def _profilePublishModule( module_name, stdin=sys.stdin, stdout=sys.stdout, stderr=sys.stderr, environ=environ, debug=0, request=None, response=None ): lock= _lock # to facilitate refreshing psrc= request or environ; path= psrc.get('PATH_INFO') if _enabled and _doProfile(path): ... code only executed when the profiler is enabled ... else: result= publish_module( module_name, stdin=stdin, stdout=stdout, stderr=stderr, environ=environ, debug=debug, request=request, response=response) return result As you can see: The overhead when ZopeProfiler is disabled is * an extra function call * 3 assignments * a request lookup * a boolean check In total: negligable compared to what the ZPublisher (not speaking about Zope at all) is doing otherwise. -- Dieter ___ 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] help with customizing error messages, Zope 2.9
Dennis Allison wrote at 2007-9-20 09:37 -0700: ... standard_error_message should be acquired. It should be possible for there to be multiple copies with the particular one to be used selected by acquisition. This does not appear to be the case for some errors in my configuration, but I am not sure why. You are right -- and I can explain why. There appears to be nothing in the Zope 2.9 zope.conf file that has to do with catching error messages. Is there some configuration that is missing to enable full custom error messages. Looking at the code: ZPublisher/HTTPResponse.py seems to have a complete set of error responses hard-wired with outputs that mimic those of the default standard_error_message. OFS/SimpleItem.py includes a method called raise_standardErrorMessage which first acquires and then publishes the standard_error_message. Zope2/App/startup.py has a method, zpublisher_exception_hook which uses raise_standardErrorMessage and is referenced in ZPublisher/Publish.py where it is used to set error_hook, but error_hook does not appear to be used. It would be helpful to me if someone who understands how this particular code works could provide some hints as to what's needed to fully customize the error message responses. We start with ZPublisher. It is this component that catches the exception and activate error handling. ZPublisher was designed as a general publication component -- to be used not only for Zope. Therefore, it has neither error handling nor transaction handling nor a few other things hard coded. Instead, it gets a module name and determines the relevant pieces by a call to ZPublisher.Publish.get_module_info(module_name). When ZPublisher is used for Zope, then module_name is Zope2. Zope2 defines Zope2.zpublisher_exception_hook as its exception hook (which does the error handling). The true zpublisher_exception_hook is defined (as you found out) in Zope2.App.startup and copied to Zope2 by the _startup call. When ZPublisher catches an exception, it calls the error hook with parents[0] (the last or second to last object traversed to), the request and the error information. zpublisher_exception_hook then looks in the acquisition context of parents[0] for 'raise_standardErrorMessage' and 'standard_error_message'. If either of them is not found, the exception is raised -- and handled by the response object in a standard (minimal) way. Otherwise, 'raise_standardErrorMessage(standard_error_message, ...)' is called. The problem which sometimes causes surprises with respect to the used 'standard_error_message' lies in parents[0]: When the exception happens during traversal, then parents[0] is not the object you may expect -- but lies above the expected object. The problem is especially bad when the exception is raised by request.processInputs. In this case, the traversal did not even start and parents[0] is the root object. Consequently, for these exceptions, you will always get the standard_error_message from your root folder -- even when the request was targeted to some object deep inside your site. processInputs may raise exceptions when you use e.g. ZPublisher type conversions, e.g. :int or :float and the provided value cannot be converted. If you do not like this, you should not use ZPublisher type conversions. -- Dieter ___ 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 )
