unit testing best practices
Hello, In my latest project I'm finally implementing unit tests from square one, trying to get as close to 100% test coverage as possible. Being new to unit testing I've noticed that almost all online information, including anything in the Pylons documentation and book, deals with the easy part: how writing unit tests works technically and what tools can help you write them. However, the more interesting (and difficult) question is not how to test, but what to test for. What to test for is something you learn from experience (i.e. testing for similar bugs to what you've encountered in the past or if a supposedly fixed bug might pop up again). Does anyone have any useful experiences or thoughts about the rationale behind their unit tests? It would be interesting to compile some best practices and general patterns for writing unit tests for Pylons-based applications (even if it are just some general tips or ideas, though specific issues you've experienced are very interesting as well). Back to my own project: I'm still working on writing the models and, of course, their unit tests. If you have any ideas about pitfalls to avoid or better ways to test here are the tests as I've written them so far: http://bitbucket.org/fmw/edgar/src/tip/edgar/tests/ My own experiences so far: - the concept of writing tests before you write the actual code from test-driven development is worth sticking to, as it is harder to guarantee the integrity of the tests if you do it the other way around, and, - it is not enough to recreate your tables before running each test, meaning you need to actually clean up model.Session at the same time (i.e. purge open transactions that might still contain remnants from previous tests). My apologies if this is outside of the scope of the list. -Filip --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

modwsgi + Pylons gives segmentation fault
I am trying to setup mod_wsgi + Pylons on my deployment server (a
CentOS 5.2 machine), but I get this error message in the apache log
files

Have you read the documentation, in particular the sections which talk
about circumstances where crashes can occur.
http://code.google.com/p/modwsgi/wiki/InstallationIssues
http://code.google.com/p/modwsgi/wiki/ApplicationIssues
Because you do not say which version of Python you are using, harder
to make a guess at what the issue may be.
Normally the problem is going to be a mismatch in shared library
versions used by Apache, PHP or some other Apache module and what a
Python module uses. In some cases the problem can be because of third
party Python modules not designed to run in sub interpreters. Not
knowing what your application does and what major Python modules/
packages it uses, again makes it harder to guess.

I should be able to read through these new docs in the next couple of days, so will provide any feedback if I have any. Thanks, that would be useful.

Mako template examples
Hi everyone, I inherited a horrible mess of Myghty templates, most of which are a cut-and-paste disaster. I've decided to undertake refactoring them and converting to Mako. The Mako docs are great and explain all kinds of wonderful things I could do. But never having had a maintainable template system for an app that displays lots of tabular data, I don't really know where I want to go. I downloaded the pydotorg examples from the Mako site, but their system is wy more complicated than I need or want [1]. Anyone know of a free software app that uses Mako, in a pretty direct fashion, and has a nice template structure I could pick apart to learn from? Thanks, Ross [1] Though the approach of using RFC-822 headers in text files that get translated into HTML is probably the most brilliant idea I've ever seen in HTML construction. If that were refactored into a standalone library, I'd use it. It's beautiful, though complicated. -- Ross Vandegrift r...@kallisti.us If the fight gets hot, the songs get hotter.

You might want to just use a class or pass local vars from func to foo. Maybe foo(**locals())? You can access the execution stack using the ``inspect`` module, or by raising a bogus exception and catching the traceback. However, this is justifiable only in very narrow circumstances, where a generic routine needs to do magic on a wide variety of callers, such as where the ``traceback`` module prints a stack trace, or the equivalent in GUI frameworks and debuggers. The rule of encapsulation argues that a function should operate only on its arguments. So you should pass everything it needs. foo(**locals()) can be paired with def foo(**kw): to get all the local variables in one step. However, if you want to modify data in the caller, you either need to put it in the return value, or pass a mutable argument (such as a list, dict, or instance) that the function can modify in place. Or if these are methods in a class, the method can modify 'self' attributes. -- Mike Orr sluggos...@gmail.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

new pylons site - ArtWeLove.com + Open Source Framework
We just launched ArtWeLove.com Everything but the /news section is in Pylons . The /news section is a customized install of MovableType. Some cookies , PHP , and a whole bunch of postgresql views in Pylons to map the MT structure tie everything together. Its got a few bugs -- we launched a day early, thanks to a partner hitting send on an email blast to 15k people , and needing to be public enough for them. sigh. The system runs on top of a framework called OpenSNS -- something that we had been developing in FindMeOn.com to prototype and deliver our Open Social Network (OpenSN) projects and standards. It's been used in a number of projects that I'm associated with for the past few years and will shortly available to all under the MIT license. ( its friends only MIT until some security issues are worked out, when they are.. its public. if you'd like to be a friend, contact offlist ) Open Social Network gives developers the ability to rapidly prototype and build production-quality web services. It's a series of Python packages and Pylons controllers , along with a standardized Database Schema, that developers can subclass, inherit, override or throw away -- allowing people to take what they need and toss the rest. The design goals were: - handle common tasks - don't enforce any sort of database concept ( everything is handled through sqlalchemy table mapping, and work continues to make column actions configurable ) - allow startups to skip the first 6 weeks of development - allow advertising agencies the ability to create web projects with speed - allow everything to be overridden or thrown away, for people to seamlessly migrate to other frameworks or custom systems to handle their data, by representing data in according to industry best- practices and standards It handles: - account creation , management , lostpassword, forgotpassword, etc - login , logout , preview - u2u relations: friend , follow , contact - profile pages w/s3 storage for images - and a whole other slew of things --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Decided that more 0.9.x is silly, might as well increment the dang number to 0.10 instead, just like 0.9.7 should've been a minor fix to 0.9.6, not a major increase. Enough abuse of these poor version numbers! :) This means any further 0.9.x releases are *bug-fix* releases, and not a larger update, like 0.10, or 1.0.

The system runs on top of a framework called OpenSNS -- something that we had been developing in FindMeOn.com to prototype and deliver our Open Social Network (OpenSN) projects and standards.

( its friends only MIT until some security issues are worked out, when they are.. its public. if you'd like to be a friend, contact offlist ) Open Social Network gives developers the ability to rapidly prototype and build production-quality web services. It's a series of Python packages and Pylons controllers , along with a standardized Database Schema, that developers can subclass, inherit, override or throw away -- allowing people to take what they need and toss the rest. The design goals were: - handle common tasks - don't enforce any sort of database concept ( everything is handled through sqlalchemy table mapping, and work continues to make column actions configurable ) - allow startups to skip the first 6 weeks of development - allow advertising agencies the ability to create web projects with speed - allow everything to be overridden or thrown away, for people to seamlessly migrate to other frameworks or custom systems to handle their data, by representing data in according to industry best- practices and standards It handles: - account creation , management , lostpassword, forgotpassword, etc - login , logout , preview - u2u relations: friend , follow , contact - profile pages w/s3 storage for images - and a whole other slew of things --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: 0.9.7 and Elixir
On Feb 24, 10:20 pm, Isaac nerk...@gmail.com wrote: Well, the best explanation I have is that these values are how I want the Session to behave, which is why I put a comment saying you may want to put something else there. That's what I was following up :-) Maybe some other values are more sane for a typical or smaller app than the one I'm working on at the moment (which is not small, and probably not typical). My reading of the SQLA docs suggests that the default values try to strike a balance between improved operational reliability and increased developer convenience. I just wondered if you thought that your app had some particular characteristics that prompted your choice --- not small, and probably not typical sounds like it fits the bill. I suggest reading http://www.sqlalchemy.org/docs/05/reference/orm/ sessions.html#sqlalchemy.orm.sessionmaker Indeed. But Mike (understandably) barely hints at the operating conditions that might prompt the adoption of a flush/commit strategy other than the default. I write understandably because the complexity introduced by the different characteristics of the various relational persistences supported by SQLA probably places the matter outside the scope of the SQLA docs. try them out, and then decide what's right for your situation/app. That's a long and potentially expensive process. I'm just sculling around trying to get a bead on things. I found this to be a useful 6- or-so scrolling pages: https://rhstack.108.redhat.com/articles/2007/02/09/design-issues-in-high-performance-transactional-applications-using-Java-and-Linux.html (for others' reference) it's fairly well-packed: differences in how databases handle concurrency, whether the database supports native operating system threads (NPTL) or processes., Generally, synthetic keys (sequences, auto-number) are preferred to business keys as primary keys, It is also best if analytical schemas (such as those used for monthly reporting systems) are kept separate from your operational system schemas. Partly answering my own (idle) question: Another thing to watch out for with persistence solutions is when and where they flush. Most persistence solutions gain a performance advantage by scheduling updates and inserts to be sent to the database lazily. By default, in Hibernate, this happens just before a query is executed or just before a transaction actually commits at the database level. The data must be flushed to the database just before a query to assure accurate results. Flushing is expensive. Most solutions do this generically without noticing which entities are actually retrieved. You can potentially gain a performance advantage by toggling the flush mode when you know it's safe (e.g. not on large projects with lots of developers of various skill levels); or by ordering your operations smartly to execute non-dependent queries together before updates (although this may be difficult to muster in a proper object-oriented/service- oriented design). Playing with the flush mode and scheduling queries is also how you can potentially run less sophisticated databases which still use row locking in a lower isolation level (with a lot of specific work) to achieve higher concurrency. I still need to figure out how that plays back into my choice of sessionmaker kwarg values but at least it's no longer an idle question. Thank you, Isaac.

Re: 0.9.7 and Elixir
Graham, Thanks for the thoughtful reply. You indeed intuited something the app is doing... its model is used to run a very lengthy conversion script from an old FileMaker 6 database (the conversion script has more code than the actual app because this database I inherited is structured preposterously even considering what's needed to work around FMP 6's copious limitations). It takes about 6 hours to run, but before I took control of flushing it took around 23 hours. I may change those kwargs when the app starts seeing normal use in a few weeks as the main activity will change to mostly reading instead of mostly writing. --i --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.
