Re: [buckminster-dev] Buckminster code-base has moved to Git

Btw, are you maintaining stable qualifiers? That is, if a bundle doesn't
change from build to build are you ensuring that the qualifiers remain
the same? I'm trying to get a sense of how people are doing this with git.
Buckminster has a qualifier generator that finds the latest commit that affects a given subtree (in this case a
project). We use the timestamp of such commits directly for plug-in qualifiers. For features, we calculate the last
timestamp for all included features, plug-ins, and the feature project itself and use that. There are some corner
cases when this approach isn't fail proof but the way we use it, it works perfectly. Our qualifiers will remain the
same as long as our code is unchanged.
And this works with Git?
Yes, indeed.
I wonder if this work could be reused in Eclipse Releng Tool [1].
The relevant code can be viewed here:
http://git.eclipse.org/c/buckminster/buckminster.git/tree/org.eclipse.buckminster.git/src/org/eclipse/buckminster/git/internal/GitReaderType.java
Take a look at the method getLastModification() at line 103
