No, I wouldn't mind it, if that is a bug we've fixed. I just mean that the tests as written never wanted to say "3 is the absolute right number of times to write this message". They only put "3" there because it made things pass. > I do think that UX is important enough to test for, particularly if > we've had a bug related to that that we've fixed. I.e. if something in > the direction of my [1] goes in. Sure, I don't mind at all a test for it. In the short-term, if you want a test that fails, I'd prefer it be separate so that we can test the useful existing behavior that _does_ work. If the multiple-messages bug is fixed, I don't mind folding them together into a single test that passes. > > It is not even clear to me that the remote-https is the one being > > swallowed (at least, I have not seen an argument or evidence that this > > is so; it does seem plausible). > > It is the case, the only ones that are going to be duplicated are the > "warn" ones, because for "die" we'll die right away in the parent > process. Right, I understand why "die" produces only one. My question was when we produce 2 on Windows (sometimes?) but 3 elsewhere, are we sure it is the one from remote-https that is eaten, or could it ever be one of the others? In a sense we do not need to worry about "why is it sometimes eaten" if the bug is fixed to produce only the one message. But it may point to a separate and interesting problem (e.g., is stderr from remote-https not reliable?). > >> > @@ -654,7 +654,7 @@ test_expect_success 'push warns or fails when using username:password' ' > >> > test_must_fail git -c transfer.credentialsInUrl=die \ > >> > push $url_userpass 2>err && > >> > grep "fatal: $message" err >warnings && > >> > - test_line_count = 1 warnings > >> > + test_line_count -ge 1 warnings > >> > ' > >> > >> ...but then why are we modifying these codepaths that have nothing to do > >> with invoking the remote helper, i.e. where we die early before we get > >> to that? > > > > If you're arguing that we should only do s/= 3/-ge 1/ for the test that > > is flaking, I could buy that. > > I'm saying that if we're doing a handwaivy-fix and saying "sometimes the > message gets swallowed" and fixing this blindly without checking how it > works, then changing "= 1" to "-ge 1" doesn't make sense. Right, I'm fine with that (I perhaps should have said something stronger than "I could buy that"). As I said, I was mostly just rebasing Dscho's patch and I think it was good enough in the sense that it was hand-waving away the whole "there may be more than one" problem. But I do agree that we'll never see more in the "die" cases, and there is no need to change them. > > I thought the point is that the outer program calling the helper would > > consistently produce the error, always yielding at least one instance. > > The helper one is generally "extra" and undesired. > > Yes, exactly.

It recently bit me twice, so maybe I am giving it more urgency than it deserves (or maybe something changed in CI to make it more likely). I do think it would be nice to fix it. I don't love your patch for the reasons I replied there (not your fault; it's inherently a crappy and complicated problem). In the meantime, I'd like to see CI fixed, as it is wasting developer's time. And that's why I called Dscho's loosening "good enough". It is hopefully a temporary state anyway. But I would be just as happy to see a similar patch which just changed the 2/3 lines to "-ge 1" (or just a straight grep). -Peff
