[ptxdist] Automatic package rebuild after rule/patch file update

[ptxdist] Automatic package rebuild after rule/patch file update

[Nikolay Kanchev]

Hello

I need to know if there is a way ptxdist automatically rebuild packages 
that have changed rule/patches files on "ptxdist go".

Description of our problem:
We have many colleagues working on same ptxdist project through SVN.
When somebody make changes to rule file or patches, then commit it to 
the SVN server, other colleagues update from SVN and call "ptxdist go" 
nothing happen because changed package already is build and have all 
state files.

Now I try to prepare script that will check before SVN update and remove 
states for changed packages, but if there is a elegant way it's better 
to use.

Not right now. I've tried to do this, but so far I could not find a way to
do this, that performs well.

Is a simple mtime comparison too unreliable? If it is, by "not 
performing well" I guess you mean the obvious possibility to hash the 
rules files...

Well first you need to find all files, that need to be considered. That
takes some time. And its far too easy to change the mtime, especially when
using an uninstalled ptxdist, so you need a hash. I tied to do something
like that and gave up when I got +10 seconds to get a 'everything is up to
date' for a larger BSP.
