<div class="im">> A) make buildsystem a subrepo (svn external for those familiar with svn)<br>
<br>
</div> There have already been many discussions on petsc-dev about how hg subrepos suck and don't satisfy all our needs.<br></blockquote><div><br></div><div>I think "our needs" are mostly wrong in this case. ;-)</div>
<div><br></div><div>Specifically, I think it is a long-running bug that the petsc-dev repository does not record when a BuildSystem change is needed. The implicitly synchronized or fragile "compare dates on the commit" model is bad.</div></div></blockquote><div><br></div><div>If the only issue is being able to get the BuildSystem revision associated with a pets-dev revision, </div><div>How about adding a hook to BuildSystem that at each commit, writes the number of the revision into a file in the pets-dev repository and does a commit in the pets-dev repository? Then all that would be done is</div><div><br></div><div>cd $PETSC_DIR</div><div>hg up -r <petsc revision></div><div>cd config/BuildSystem</div><div>hg up -r `cat $PETSC_DIR/BuildSystemVersion.txt`</div><div>Which I am sure can be done automatically with a hook.</div><div><br></div><div>It's not high tech, but it would work, right? Plus this could be done a posteriori for all past revisions of BuildSystem.</div><div><br></div><div>Blaise</div><div><br></div><br><blockquote type="cite"><div class="gmail_quote">
<div><br></div><div>Anyway, I thought the real concerns were that old versions of Hg didn't manage subrepos consistently, not that the general model was wrong.</div></div>
