Nevermind I.e. the test_cmp here is now, given what you mentioned I'd have been fine with the grep, but stealing the show_cr also works. I suppose it's also abetter as a targeted fix, since the point of this patch is specifically to fix a bug where we wouldn't do the right "steps" in-between with the progress bar, in addition to the end-state not being correct. Are the small number of missing steps above expected? E.g. 1-2/7 and 5/7 in the last tets above, ditto the rest? Mm, yes, looking at assign_blame() in blame.c we'll "skip" some. So if we ever change that algorithm we'll need to adjust these, but it's probably good to notice that then, even if the test_cmp here does implicitly encode a bit of internal implementation details, i.e. when exactly we update the progress bar. ^ permalink raw reply [flat|nested] 5+ messages in thread

I do not think that is something we want to test, or distract the developers by forcing them to update the skipping hardcoded in the test. Is it easy to grab the last progress message from the output? What we care, and have cared in the past, is that we expect that the 100% is paired with the number of lines in the ranges, and the progress actually ends at 100% (we had different bugs that did not bring the meter to 100% at the end), so checking that end result would be what matters most, e.g. tr '\015' '\012' output | tail -n 1 or something? ^ permalink raw reply [flat|nested] 5+ messages in thread

I realized I left a garbage line in the v3 patch that I would like to never see moving forward so I will send a clean patch for v4 just like the previous ones, hope that's not a problem.
