PyS60 application release build toolchain

A common question for Python for Series 60 newcomers is how to build standalone Symbian applications from Python source code. We have been using Makefile based toolchain internally. I describe it in this picture, I didn’t bother to add thumbnail for the image, since it’s a 3400 pixels wide diagram.

The diagram describes building a PyS60 application with some Python extensions (Symbian native C++) mixed in and bundling it all to one downloadable SIS file. The application will appear as any first class S60 application in the menu and the user does not know it’s running Python internally, besides bad installation experience (it challenges Microsoft installers with all those unnecessary yes/no questions), extra uninstaller entries and slow start-up time.

The biggest problems are caused by embedded SISs (SIS inside other SIS files) which are not treaded very wel by several Symbian parties.  In theory, it could be build one monolithic SIS, but you’d need to recompile PyS60 from scratch and patch UIDs inside it for your own UIDs received from symbiansigned.com. We are planning to explore SCons based build solution to address this problem, since Makefiles are a bit unflexible with tasks like PKG file and UID range generation.

Here is a PKG file example for final user distributable SIS file.

Also, see UIKludges project for additional details for PKG files of Python extensions.

Ps. I would have put this thing to wiki.opensource.nokia.com, but their webmaster email address is non-functional and one cannot upload images to their Wiki.

The good, the bad and the Zope

I want to use Zope 3 interface package to write component architecture i.e. have a plug-ins easily in Python. Zope 3 interfaces are very handy and, which cannot be conducted from the name, are available outside Zope too. From my prior experiences I know that Zope 3 interfaces package is one of the best and most underrated Python packages out there. It even influenced to the new design of Python 3k.

Well then… I haven’t used Zope 3 interfaces standalone before, so the first thing what I do is writing “zope 3 interfaces” into my Google search this.

This page comes up.

It’s horrible - the very reason I write this quick blog entry. Some notes below (I have written things from the point of external visitor - I have hands deep in Zope myself, so you don’t need to clarify these things for me or teach anything)

In the post “No, you are not smart enough for Zope” Martjin Faassen highlights some problems of Zope community. “It’s hard to get good content written” Martjin claims. I disagree. Whoever created the page originally could have thought what people coming to the page want. They don’t want to decrypt the brain core dump of hardcore Zope developer. They want to know what is this thing, how this thing is beneficial for them, how do I get started with it and how do I use it.

You all know how Internet works. You all have visit on web pages. You all are customers for the same thing you also produce. So writing a basic web page is not something you couldn’t do.

Hints:

Pardon me the tone of this post. Zope is the 23th best thing out there, but the Zope community has stagnated badly in some aspects. Some things were acceptable ten years ago when web was still young and Python developers hardcore, but if you don’t keep with the pace you lose all the mindshare.
