Thomas,
I wonder if this feature could be integrated into We Sun Solve website, as from the patchdiag.xref archive, I could generate a patchdiag.xref with latest revision as base and then add older revision of patches into it by looking at patchdiag.xref archive.
Yes, you're right. Theoretically one should be able to build a master xref file by joining the old copies, which could then be used to show patch dependencies for older revisions as well.
One problem is that a simple "cat */patchdiag.xref | sort | uniq" won't be enough. One would have to take care of the R/S/O flags on past patch revisions. and it would be very hard (or, impossible) to verify whether the result is actually consistent.
As far as PCA is concerned, there's another problem - its data structures assume that there is only one revision per patch (the main array is indexed by patch-ID only). Changing this would require a re-write of big parts of the code.
Martin.
