[R-pkg-devel] Query about broken reverse dependencies that already are broken

[J C Nash]

This is a question about how things are done rather than a request for a fix.

Yesterday I re-submitted my optimx package with some small but important fixes
(e.g., one place where one solver would miss catching function evaluation limits).
I'd done a revdepcheck that came up with "Wow, no problems", but in fact one of
the revdeps had a test failure which was already flagged in its checks list on
CRAN. A package test example had a singularity on some systems. This can happen with
nonlinear function minimization due to very small changes in arithmetic and
approximations of different systems. Putting in checks and "graceful failure"
for such conditions is the ideal for optimization solvers, but it isn't easy.
Some of the changes in the optimx update submitted are of this flavour.

When the submission checks came back this morning there was a
"Changes to worse in reverse depends:", even though there really is no change.
However, I then got a msg "Thanks, on its way to CRAN."

Am I correct in assuming a manual review passed the package (which hopefully I
did get fully compliant)? Or will I get an eventual "please fix" for something
clearly outside my scope of action?

As indicated, at the moment this isn't a request for help, though that may come
later.

Cheers,

John Nash
