Dear developers,
I have a question regarding bug dependency in LibreOffice.
While I was studying the blocking and blocked bugs, I found that in
LibreOffice, after 2017, there is a sudden spike in the number of the
found dependencies [1 <https://arxiv.org/pdf/2011.05382.pdf>].

/Figure1- The monthly evolution of mean depth and degree of the Bug
Dependency Graph for the LibreOffice project (x-axis corresponds to the
year and /the /y-axis corresponds to the mean depth and degree of the
graph)./
May I ask what is the interpretation for that sudden increase? What
happened that developers started to find these many bug dependencies?
Thank you for your help in advance. I hope that I contacted the correct
list.
Hello,
others have already explained that your chart ends up mainly looking at
the categorisation of our bug reports. You should be aware that Mozilla
also uses meta bugs as a way of tracking bigger tasks. Random Firefox
example, about adding VA-API hardware decoding support on Linux (you
need to be logged in to view the tree):
https://bugzilla.mozilla.org/showdependencytree.cgi?id=1210727&hide_resolved=1
So meta bugs are basically just another way to associate our reports
with useful meta data. Many of them could be replaced by adding another
level into our product - component hierarchy.
You can study all of our meta bugs conveniently here:
https://wiki.documentfoundation.org/QA/Tracking_Bugs
As you can see, some of them are meant to be permanently open and some
of them have a clear scope (such as fixing all regressions from some
particular change).
It is good that your paper is still a preprint because it needs
revision. There are several parts that do not make sense to me. For
example, on page 15 you say
"The sudden change in decision of triagers for not prioritizing bugs
with high depth leads to accumulation of the bugs in the system and a
much higher complexity of the BDG."
This conclusion has nothing to do with the reality of LibreOffice
development, because the cases where prioritising in itself leads to
action are not very common. Typically the reports of highest priority
and critical severity are brought to the weekly engineering steering
committee meetings for discussion.
If you want to discuss more, we can schedule a call. You can email me
directly.
