[v0.17] Dependency graph: Graphviz failed to create an image file

industromatic · Post by **industromatic** » Sun Sep 10, 2017 6:33 pm

I'm not a newbie, I have gotten a small amount of successful experience with freecad. I seem to aim for a top down parametric way to use freecad that is different than most. I have a doc with rather short chains of anything and yet it already is failing to make a dependency graph.

I get the error: Graphviz failed to create an image file.

My goal in creating this doc was to have independent modular reusable chunks of 3D parts to combine to make things, so it couldn't have been that deep a dependency graph.

A simpler file does create a dependency graph with same version of freecad.

Interesting, with the following version on macOS, I can create a graph of that file with no problem.

[graphviz: 2.36]

However, I get the same error as you on Windows (same freecad version 0.17.12058, but using graphviz 2.38).

On Windows I have graphviz 2.38 and when trying to create the picture I get a crash report that dot.exe stopped working. dot.exe is the utility of graphviz that creates the image file.

When exporting the graph to an external file with

Code: Select all

graph=App.ActiveDocument.exportGraphviz()
f=open("graph.viz","w")
f.write(graph)
f.close()

and then using dot.exe with:

Code: Select all

dot.exe graph.viz -ofile graph.png

it prints a couple of warnings

and then crashes.

I tried to disable the new depemndency-graph stuff like grouping, but it still fails:

BaseApp - Preferences - DependencyGraph: GeoFeatureSubgraphs = False
BaseApp - Preferences - DependencyGraph: Unflatten = False

So it seems there is something else going on.

I don't need this freecad doc for anything, but it could be a repeatable result debugging opportunity. Should I file it as a bug?

Post by **wmayer** » Wed Sep 13, 2017 8:24 pm

Looks more like a graphviz bug because the dot utility crashes, not FreeCAD.

peterl94 · Post by **peterl94** » Wed Sep 13, 2017 8:29 pm

It works with version 2.36 on both macOS and Windows....maybe it is a regression on their part. I wonder if there is a way to work around it.

47 -> 12[arrowsize=0.5, style=dashed];
49 -> 32[arrowsize=0.5, style=dashed];
50 -> 32[arrowsize=0.5, style=dashed];

then dot doesn't crash any more.

Playing a bit further only these two lines are responsible to make dot fail:

39 -> 32[arrowsize=0.5, style=dashed];
39 -> 14[arrowsize=0.5, style=dashed];

But as there is nothing wrong in the syntax this must be clearly a graphviz.

Post by **GeneFC** » Wed Sep 13, 2017 11:45 pm

I had regular crashes of dot.exe for a long time. I reverted from version 2.38 back to 2.36, and the crashes stopped.

I just tried the supplied file from the OP. It crashed with 2.38 and worked fine with 2.36. Some sort of regression or a new "feature" in GraphViz.
