<div class="moz-cite-prefix">After a bit more investigation, I found
that we can change the git show command to include -U1 (which
means show only 1 line of surrounding context). This will limit
the amount of times 'context' matters. <br>
<br>
So I'm sure the next question is, why can't we simply -U0 and
show no surrounding context, before passing into git patch-id?
Well, it seems when I do that, the results of git patch-id are
several lines... which breaks the current implementation. <br>
<br>
However, it does come up with identical results for git patch-id
if done that way, at least for the first segments of every line. <br>

<br>
For now, though the current implementation will be broken by using
-U0 because we do not expect multiple line output. I'll test a bit
more and see if I can improve this for next time. <br>

Great idea, Rob! I would also appreciated if there was a JIRA for
each component as Nick suggested.
<div class="">There are 30 reports for integration tests. Looking
at a few, it was either just a change in a pom or a false

<div class="">You see, there is nothing different - apart from
checksums, it's the bundle version. But that is outside of the
changes - that is just there for context, not part of the
commits. Any idea why the patch-id is different?</div>

Also, might be easier if you put the run info into

from mail. <br class="">
<br class="">
btw. it looks like this tool actually is very good at

<br class="">
<br class="">
First, I disagree that these are false-positives ;)
These are commits that are in maintenance that aren't in
master. <br class="">
<br class="">
And, in all honesty, I think it'd be a mistake to simply
filter them out. I think it's much better to list the
false positive and let the component owner use his
judgment whether the patch needs further inspection or
not. Such simple version-changes will be very very easy
for a human to spot as irrelevant to master. This may
cause the repository owner to waste 2-3 seconds for each
commit, but it guarantees that every possible unmatched
commit is found. <br class="">
<br class="">
I think this is much better and safer than possibly
adding some logic to filter out version changes and
later discover that the logic was wrong and so it was
hiding legitimately missing commits from being shown.
Also, since we're not inspecting the patches at all, but
rather comparing patch-id's, it would make the script
much much more complicated. <br class="">
