java.lang.IllegalStateException: Cannot find color #000007

yung5133 commented 1 year ago

The latest version of the PlantUML-server is deployed on a server using docker-compose. However, in specific scenarios, an error occurs: "java.lang.IllegalStateException: Cannot find color #000007".

yung5133 commented 1 year ago

Just run code like this:

@startuml !include <C4/C4_Context> !include <C4/C4_Component> !include <C4/C4_Container>

Boundary(a, "Boundary A") { Boundary(b, "Boundary B") { Container(c, "Container C") } }

Sorry about that...

Last version (7.1.0) of Graphviz is crashing with some input data (example)

This is connected to https://github.com/plantuml/plantuml-server/pull/268

We are going to investigate

Anonymodesu commented 1 year ago

Is there a version of GraphViz that we can fall back on?

fgreinacher commented 1 year ago

I tried with 8.0.2 - same thing happens within the container.

It works with the same GrahpViz version locally on my Mac, so this seems to be a dependency/system issue.

arnaudroques commented 1 year ago

I am wondering if expat-devel library is missing during graphviz compilation.

Could you run configure with option "./configure --with-expat=yes" before graphviz compilation. And check that libexpat is found when graphviz compile?

Thanks!

Great hint, that was the issue! The C4 diagram now renders properly:

Adding expat-devel does not fix that issue. The server log only shows this:

Any ideas what could go wrong there @arnaudroques?

Yes: here, I think that Graphviz is really crashing :-(

Could you test other Graphviz version so see which one are crashing and which one are not? Maybe it has been fixed in version 8, or maybe it's working in version 6 or 5.

arnaudroques commented 1 year ago

On second thought, it might be related to graphviz configuration/build, because I made it work on a graphviz version 7.1.0.

fgreinacher commented 1 year ago

stroke="transparent" has changed to stroke="none", could that be relevant?

arnaudroques commented 1 year ago

No, both are fine.

However, it looks like it's working with version 8.0.2, right? What I mean, is that when Graphviz is crashing, it does not generate any SVG. So here it looks it does not crash. So is the example working?

I am more and more confused :-)

fgreinacher commented 1 year ago

Yes, dot can render this, also in 8.0.2. The problem only occurs when rendering through PlantUML server, e.g. http://localhost:8080/plantuml/uml/fP9HIyCm58NV-oj2V2qpcLkwqTx2vkfM60ngHL5ywDgmH6jRaXPrO__Tr3bmJ0VYXHouzznxu8DaSgMIIg2ca6zeOnLbnZMlW7Hw0qOfTIsL5C-xoU2YBJFXBx98LQarrAhXhgLvebAXvPf3dn3JDyjTQ9etkkQALGHjycJ9Sy3OFNBHHjVlEGTTvZ9pqp8l5U0pqXR3xkVTaza4d7vru7dnQ3mFq7XwkPWlelssWz5LU1TChiFx070StGGOtOQJU0QOcYWq2yBfB0RSxMFVYoFp9hvtlfEebJRKzty2eDy0ZcnAJW9ISe9mz2V2yU-4m-u_00t18Q4WXFRGWnP9nK7njBRtflqgire0xVHxb3775bokH6s-XyFOiElO1tG1VdGjQxlTxkK3

Ok, I think I have an idea. Could you check if this simple example is working?

And check if dot -Tpng dot1.txt is working in the container?

Probably both tests are failing.

This would probably mean that GD library is missing during Graphviz build.

Yes, both are failing, the latter with Format: "png" not recognized. Use one of: canon cmap cmapx cmapx_np dot dot_json eps fig gv imap imap_np ismap json json0 mp pic plain plain-ext pov ps ps2 svg tk xdot xdot1.2 xdot1.4 xdot_json.

I'll check whether installing GD helps!

@arnaudroques Looking good, changes are here: https://github.com/plantuml/plantuml-server/pull/272

camaeel commented 1 year ago

@arnaudroques is there any plan to release this fix? Current tomcat and tomcat-v1.2023.5 tags in docker hub are broken.

Yes, sorry about that. We've just pushed a new version. Tell us if it is not working for you!

camaeel commented 1 year ago

@arnaudroques Great, thanx!

Anonymodesu commented 1 year ago

Thanks for rolling out the fix so quickly!

fgreinacher commented 1 year ago

@arnaudroques Could you also push a stable tag for this image? We usually don't pull latest 🙇
