[Erp5-dev] svn-buildpackage - proper way to use SVN for .deb packages

[Łukasz Nowak]

Hello,

Right in in spec/debian and spec/ubuntu repository paths packages are 
kept as .dsc file, uncompressed package sources, its source and binary 
builds. That way of using repository is inconvenient:
  - it is very hard to see changes made to original sources
  - it is very hard to see changes in package definition
  - there is not automatic builder support

There is 'svn-buildpackage' system, designed specially to track changes 
of packages (and its original sources) in version control system.

svn-buildpackage is avaiable for debian (etch (aka testing) and up) and 
its derivatives like Ubuntu (dapper and up). This set of scripts 
automates changes of package and its original sources, builds package, 
creates new debian-way revision, etc. All (uncompressed) package 
information are kept in repository so it is very is to track changes in 
package, create branches and tags. Typical package tree generated by 
svn-buildpackage is attached.

There is need to made conversion from current system to 
svn-buildpackage. But there are scripts (attached tree was initially 
imported from https://svn.erp5.org/repos/public\
/spec/debian/unstable/python-reportlab/python-reportlab_1.20debian-2.dsc) 
which allows easy conversion from non-versioned system to versioned one.

I hope that I'll provided enough information about svn-buildpackage. I'm 
testing it right now on our SVN server - it is quite good, works on 
debian/unstable and ubuntu/dapper without any problems.

Because such conversion has high impact on current /spec repository I'm 
requesting for approval. After one I'll take actions:
  * convert python-reportlab in Nexedi's repository to svn-buildpackage 
system, by replacing contents of /spec/debian/unstable/python-reportlab 
with generated by svn-buildpackage tree
  * create HowTo about building packages for such repository on ERP5 wiki
  * convert rest of *external* packages (!^erp5-) to svn-buildpakcage system
  * after proper policy of ^erp5- snapshotting - convert them (well - 
this is another topic)

Additionally there is svn-autoreleasedeb system for automagic build of 
released debs.

Thanks,
Luke
