| Re: [tycho-user] What are baseline repositories good for? |
Hi
I suspect that I am re-ranting about the inadequacy of jgit timestampProvider which I raised in Bug 529972 [1] where my conclusion that reference content was essential was dismissed as CLOSED INVALID.
It looks as if baseline repositories are pretty much the solution I was advocating. Is this the case?

Hi all, Hi Ed, Tycho has everything in place to 1. Prevent production of new artifacts when there is no payload change in the current module/bundle source (saving QE effort and servers bandwidth on updates) and 2. Guaranteeing versions evolve mostly forward compared to previous release, forbidding the nasty qualifier only changes. Couple this with automation of API Tools at build tile, then you get a build reliably producing as few nnew artofacts as possible, reusing as much as possible, preventing from bad version stagnation or regression and enforcinfmg semantic versioning. Many serious Eclipse.org projects (incl. Platform) do successfully use those as qualitu gates. Anything that's not successful for you here is either a configuration issue on your end, or a bug in Tychi, which should at least be reported.

However that good day is totally depend on the fairies, since an unsound superficial view of GIT dependencies rather than a true has-it-changed-test is used. Do not use.

The wiki page sais: The end result is that build output contains new versions of the artifacts that did change and baseline version of the artifacts that did not. And "change" meaning version, id and "content". How is "content" defined here? I will have follow up questions :) Thanks, Felix -- Linux.
