...No, useless bug reports don't lead to a solution, ie., that particular 
bug won't get fixed as a result of the report! That's what these people 
are trying to say. Sure the point of bug reports is to get the bugs fixed,
don't you think? :-/ ...Or do you thing it's only secondary to get them 
fixed.

I'm asking the same thing from you as I did from Mark (it still remains 
unanswered)... What's your suggestion, how should we have solved this 
particular case? Do you join those that ask for developers to "invest" 
time to repeatedly go through the commits that are not guilty? ...One 
would never find the solution by that method :-/.

Yes, I'm fine that you don't want to help (or would want but cannot help 
like have been with many of nearly impossible to reproduce bugs with TCP 
lately) but the sole consequence is that the bug remains unsolved, it's 
plain simple. That's until somebody else is affected and reports and we 
get the necessary information. Or alternatively somebody just reads the 
offending code (possibly much later) and begins to wonder why there's this 
particular thing missing there (this is in fact not related to the bug 
reports at all, many bugs are found this way but it's not a thing one
can force to happen in a timely manner :-)).

Please reread the thread, this couldn't be farther from the truth...

...Dave had suggested Mark would have to bisect, I suppose this was after 
founding out that there wasn't anything particular that should cause this 
kind of behavior, or at least he couldn't find anything even suspicious 
looking. Mark, with rather demanding tone, was _also_ asking for that 
"somebody" who did all those TCP fin/closing changes (that would be me) to 
be responsible over them, ie., those parts that Dave had checked and found 
not suspicious (and bisect also proved them innocent later on). Yes, I 
then went through that "mountain of commits" which Mark "was not willing 
to do" himself. I invested the time even after Dave had also come to the 
same conclusion as I again did, that there is nothing wrong with the 
particular parts of the TCP. Funny, since it seems that even Mark himself 
had come to that same conclusion as both Dave and myself then came (though 
I cannot really speak for him). So I was third one to check those parts 
which were then found not guilty, would I be angry about it, I would call 
that plain waste of time :-). Please note too that I would have gone 
through them without his remarks as well to just check the thing I already 
knew.

So what's the problem with that. The thing that Mark wasn't very willing 
to go through that "mountain of commits" and made some accusions that one 
shouldn't ask user to do that, yet he was doing the same thing, asking for 
me to go through that "mountain of commits". I don't find that as polite
as you do (and maybe you don't honestly either), especially as that was 
_already done by Dave_, yet it wasn't enough for him.

But you would feel qualified to tell how the police/doctor must handle 
it? ...That was the main problem.


To conclude I moved this your case down here...

It's perfectly fine that you report bugs, even with little time :-). But 
then if you are asked to do something that is necessary to help developers 
and you are not willing to do that, please don't start adding demands 
(it might actually be quite hard to restrain oneself from adding hidden 
"attacks" to wording, at least for me). Also we have to then accept the 
concequences, ie., the bug won't get fixed because of that report 
(unless something comes up later which connects the pieces).

I thought the same earlier, but I want to try to correct the misunderstand
you are tryng really hard to get here :-).
