Dear pyxser users, I’m pleased to announce that I’ve released pyxser-1.5.1r. This release includes a new argument for deserialization functions, so you can skip the initialization construct by using cinit = False as argument, this improves performance, but leaves uninitiated objects, without calling its default constructor.
The ChangeLog for this release is as follows:
1.5.1r (2010.10.11): Daniel Molina Wegener <firstname.lastname@example.org> * On all files: algorithms were optimized, the code was flattened applying "The Zen of Python" and the performance was enhanced in 10%. * Was added the cinit argument to deserialization functions, which control whether or not, the default constructor is called, instead of creating a raw instance of deserialized objects. Thanks to pyxser users for their feedback.
The cinit = False argument makes pyxser to skip the default constructor, calling PyInstance_NewRaw() instead of the default constructor. This skips the initialization code on the __init__() method. The impact on the performance — if your objects do not require of the default constructor — is as follows:
This enhancement is minimal, but saves time when you work with very simple objects. To take a look on the documentation, the pyxser extension is self documented, so you just need to call pydoc -p8181, connect your browser to http://localhost:8181/ and search for the pyxser extension documentation.
I hope that you will enjoy this release :D
