[issue18945] Name collision handling in tempfile is not covered by tests

[R. David Murray]

R. David Murray added the comment:

If they are part of a bug fix, then sure.  That wasn't clear from this issue, though.  On the other hand, if the tests in that other issue cover the actual bug, and these have any chance of *introducing* test failures (especially if they are heisenburgs, although I'm assuming the point is that they are not), then I'd say no.  The issue with backporting tests isn't about "maintenance burden" (backporting tests actually makes the maintenance burden smaller, not larger).  The issue is potential effectively spurious test failures in the field in a maintenance release.

To put it another way: the right place to find test bugs is in a feature release, which we then fix in the next maintenance release.  We do *not* want to find test bugs in maintenance releases.
