120687 - show bug list as dependency graph

Status: NEW

(Bugzilla :: Dependency Views, enhancement, P3)

Description

[John Vandenberg]

The best example of how this is useful is a 'Release Blockers' bug list.  A list
or a tree of these is not the best way of finding which bugs need to be chased
up first.  The graph also shows area's which are going to put most stress on the
tree, and thus might be better to lock the tree or create a branch.

So what happens if the bugs are not necessarily connected to each other?

CCing myk, as he's templatising buglist.cgi.

Attachment: Dependancy graph from buglist

This is our release blockers dependancy graph from a buglist:
id=6,16,26,33,39,42,64,113,115,116,117,120,133,134,137,142,143,147,148,156

They are displayed on the left of the graph, and from what I can see graphviz
is placing sets of bugs top to bottom ranked on number of edges.

Not a bad idea, and it looks like the issue of bugs being related to each other
is taken care of in the screen-shot, where (correct me if I'm wrong) unrelated
bugs are lined up vertically without any lines being drawn between them.

This patch is missing an implementation, however, since the version of
showdependencygraph.cgi in the CVS repository only accepts a single bug ID from
which to build the graph.  Are there patches for that CGI as well?  If so,
please attach a patch file with both patches included.

Rescinding my "needs-work" status since the implementation I thought was
missing exists in bug 120686.

This has been templatised, + tags should be lowercased.

Comment 9

[Dave Miller [:justdave]]

Bugzilla 2.20 feature set is now frozen as of 15 Sept 2004.  Anything flagged
enhancement that hasn't already landed is being pushed out.  If this bug is
otherwise ready to land, we'll handle it on a case-by-case basis, please set the
blocking2.20 flag to '?' if you think it qualifies.

Attachment: Patch to 2.19.2, adding graph view of selected bug list.

Calling structured "graph" representation of buglist will be appropriate in
links to alternative bug representations as:
"Graph | CSV | iCalendar" 

To do so, just apply this small (3-lines) patch.

bug 371030, bug 12992, bug 120687 seem to be dupes of each other.
