Forks trace or filtering is broken (forks segmentation)

[andry81]

I've found that several forked repositories does not show anymore on the list. More over, the filter field in the repositories pane section works differently and does not show all the forks of mine too.

Looks like GitHub has made some breakage or altering changes to it.

Example:

https://useful-forks.github.io/?repo=dirk-thomas/vcstool

The list does not contain the https://github.com/ros-infrastructure/vcs2l fork anymore. But the list had it even after the rename (old link: https://github.com/ros-infrastructure/vcstool)

It has disappeared from other lists too:

https://github.com/dirk-thomas/vcstool/forks?include=active%2Carchived%2Cinactive%2Cnetwork&page=1&sort_by=stargazer_counts
https://devnoname120.github.io/useful-forks/?repo=dirk-thomas/vcstool
https://github.com/techgaun/active-forks

I suspect it has something to do with the filtering, because the filter field on the repositories pane section now does work differently:

https://github.com/orgs/andry81-forks/repositories?q=vcstool

If try to clear the filter, then the https://github.com/andry81-forks/vcstool--ros-infrastructure appears on the list.
(does not repro anymore)

I've cloned both dirk-thomas and ros-infrastructure. But somehow the ros-infrastructure fork is in detached state with the parent repo.

Seems there is a feature on the GitHub to intently loose a fork relation: https://stackoverflow.com/questions/16052477/delete-fork-dependency-of-a-github-repository/79633266#79633266

This is definitely making the entire forks tree segmented. To prevent this you have to save the link to a parent for each forked repository.
