13324 - Dependency graphs don't work in Bugzilla

Status: VERIFIED FIXED

(Bugzilla :: Creating/Changing Bugs, defect, P3)

Description

[Erik Talvola]

Tried to get a dependency graph for BUG #12658.  This URL on the page:

http://www.research.att.com/~north/cgi-bin/webdot.cgi/http://bugzilla.mozilla.o
rg/webdotbackdoortobugzilla/data/webdot/12016.dot.map?15,7

is a bad link.  Specifically, the component of it:

http://bugzilla.mozilla.org/webdotbackdoortobugzilla/data/webdot/12016.dot.map?
15,7

is a bad link (which is probably the problem).  The CGI script referenced seems
to exist.

No, that's not the problem.  Trust me.  I know how busted that URL seems. It has
to do with me working around a bug in webdot where it doesn't deal quite
correctly with bugzilla URLs.

No, the problem is worse: it turns out that our dependency graph has gotten so
complicated, that to render it, webdot generates an EIGHT MEGABYTE gif file.
Netscape is unable to cope with it (in fact, I haven't found *any* program that
can cope), which is why Netscape gives you a broken image icon.

I have found a way to force webdot to put a maximum size on the image.  It will
now limit things to be 64x64 inches.  Which is probably still too big, but in
reality, it generally wants to make a graph really big only in one dimension.
Forcing that dimension down to 64 inches causes the other one to be, like, one
or two inches, and we can cope.

This sucks.  I didn't think the dependencies would get complicated enough to
start having *this* kind of problem for another few years...

per Terry, auto-verifying any resolved bug that hasn't been touched since before 
2.10 was released.

The URL is different now - but not working (for me).
Trying to display the graph of this bug
http://bugzilla.mozilla.org/showdependencygraph.cgi?id=13324

I get a broken image. Looking on the link for the image

http://www.research.att.com/~north/cgi-
bin/webdot.cgi/http://mothra.mozilla.org/webtools/bugzilladata/webdot/24155.dot.

WebDot reports:

URL "http://mothra.mozilla.org:80/webtools/bugzilladata/webdot/24155.dot" was 
not found

This is a site-specific issue, Bugzilla isn't broken, mozilla.org's installation 
is.  The original bug in Bugzilla that is described in this bug is fixed.  The 
mozilla.org specific issue is covered on bug 55418.

moving to Bugzilla product, re-verifying fixed, since it got reopened on accident.
