While trying to bisect a module failure for #133135 I've found that
the following commit range 2d74dcf..394d2d3 (3 commits) prevents
Porting/bisect.pl from running further with the following messages​:

I remember from it's docs that it should skip at least some kinds of

Or should bisect.pl just blacklist those revisions?

Can you provide the specific way in which you invoked bisect.pl?

Thank you very much.

I remember from it's docs that it should skip at least some kinds of
failures, so if this is not one of them - should it be also avoided?
Or should bisect.pl just blacklist those revisions?

Can you provide the specific way in which you invoked bisect.pl?

Thank you very much.

I must be responsible for these, though I don't understand how it
happened. So, yes, it should avoid this block of commits. I'll look at it.

See attachment, which I also attached to 133135.

I agree that the make-non-completion in the first two of the three commits poses a problem for bisection going forward. I'm not sure if we currently have any code in bisect.pl or bisect-runner.pl that can permit us to skip over these two commits.

Thank you very much.

Subject: [PATCH] PATCH: [perl #133136] bisect runner

bisect runner is supposed to keep going if the particular revision being
tested fails to compile.  But it wasn't.

Nicholas graciously diagnosed the problem.  When the enhancement for
testing when a module got broken, the code to do so was placed before
the check to see if the build for this revision crashed.  It's simply a
matter of moving that module code to after that check.

I believe this patch should go into 5.28.0, and am putting this ticket

1) This changes only a Porting/ script so does not affect the perl

2) It fixes a bug that could otherwise create hassles in finding bugs

I agree to this.

1) This changes only a Porting/ script so does not affect the  perl
interpreter code at all, nor its tests.

This is the main reason I'm okay with it.

2) It fixes a bug that could otherwise create hassles in finding bugs
when they occur.

And this is why it's important.
