Hello Rahul,

Pyrpm is described as "PyRPM is an experimental project to look at rpm package management". It is a prototyping tool. Not a implementation meant to be used by users currently unlike Yum (which I think is what you are referring to as pyyum).

okay, you did never use PyRPM.

I don't know why you want to assume that. My use is irrelvant to your question on whether pyrpm duplicates yum and RPM. Answer: No. it doesn't. pyrpm is clearly described as a experimental prototype in it's homepage at http://www.jur-linux.org/pyrpm/. That's the first hit in google btw.

Your use is relevant when it comes to the question if your opinion is in any way better founded than that of google.

It is called yum and not pyyum which would a redundant name since the only existing implementation of Yum is in python. If you are a Fedora user, the fact the name is yum should have been obvious.

The PyRPM suite includes pyrpm - a rpm replacement in pure Python, pyrpmyum - a yum reimplementation build on top of the pyrpm libs, pyrpmkickstart - a tool for doing kickstart installations from within a running system into hard drives or disk images. There are also a number of test scripts for checking rpm based distributions for various problems.

The whole software suite is written from scratch in pure Python. This was done to be independent from upstream projects (rpm, yum) and to be a rapid prototyping testbed for experimental and/or new features/modifications. It also provides a basis for various large scale tests that were either too complicated or simply not doable with the existing tools.

It was (and to some extend still is) experimental in the sense of

1. Developing/using advanced techniques not (yet) found in rpm and yum. This includes better multilib handling, auto eraser, better depsolving, high performance and low memory foot print. I am just now porting the first lessons learned there to yum.

2. Not having a large enough user base to be considered as stable. Due to a large number of tests we have done with that codebase we're now quite confident that we have at least reached a similar stability as the current version of yum.

I hope that makes things more clear.
