Corret. As posted, the patch changes existing behaviour _unconditionally_ so I don't not think I can say with a straight face to upstream that they should take this. And also: you can turn them on for your builds, I won't at first, but advertise so that more users can test it. "Eventually" I may turn them on as well. The R "universe" is _at least_ the (currently around) 10600+ packages (yes, really, 10 thousand) on CRAN. The fact that we successfully rebuilt our 400+ is important aspect but nowhere near comprehensive enough. | However, since I'm not familiar with the full R codebase I was waiting to see if upstream had any further comments, because even with the getOption() change there might be other consequences that I didn't foresee. In this case it would be beneficial for Debian's behaviour to exactly match upstream, so we get the same bugs (if any). | | > Ximin, looking at https://anonscm.debian.org/cgit/reproducible/r-base.git/log/?h=pu/reproducible_builds | > I believe it would be best to merge those two (top most) commits into one? | > | >> A decent longer-term strategy may well to stress-test the patch by including | >> it in our builds for a while.

Exactly. | That is why I wanted to wait for upstreams' comments first, before adding the getOption guards - which are relatively minor IMO, compared to what the full patch does. Correct if I am wrong but you have not heard back from upstream, have you? [ That is not uncommon for posts on r-devel. Sometimes one needs to be persistent, and/or ally with an R Core maintainer. Which is pretty much what I suggested early one. ] | I also haven't tested other potential tools that might process R rdb files, who might for some reason expect absolute build paths. Correct as well. We are moving in the right direction, but we should not rush this. Upstream *is* sympathetic, they have taken an earlier 'repro build' patch.
