CDash server responding with `Error parsing XML in stream at line 1: syntax error` for Coverage XML

I'm hoping this is a CDash issue and not a CMake/CTest issue but let me know. After calling my dashboard script for Windows/MacOS I'm generating a Cobertura XML and parsing with ctest_coverage() this eventually gets the code coverage successfully and prints

Covered LOC:         4275
Not covered LOC:     7736
Total LOC:           12011
Percentage Coverage: 35.59%

But when uploading with ctest_submit(), it throws the error above in the title:

So every submission is successful except for Coverage.xml. This error only happens when it parses with Cobertura XMLs so far in my testing but that's all that we can use at the moment. I'll post the top few lines of the Coverage.xml file below:

I'm able to reproduce this same issue on MacOS as well. Any ideas or further logs I can provide?

I should also note, the dashboard does not show any new Coverage build when this uploads as well.

What version of CDash are you running?

[tamuseanmiller]

What version of CDash are you running?

The latest currently (3.1.0?)

[tamuseanmiller]

Any ideas or more information I can provide here?

[williamjallen]

I don't see anything out of the ordinary in the file you provided, but @zackgalbreath probably knows this part of the codebase better than I do.

Things that might be helpful if you're able to provide them:

1. The project name (or at least the characters being used in the project name)
2. A more complete Coverage.xml
3. Any relevant CDash log data

[tamuseanmiller]

Hey @williamjallen, thanks for taking a look here. I'll try and provide some more of this information, but as most of this is proprietary information I will attempt to censor some things.

1. The project name uses dashes like this: test-name-proj with all letters
2. Coverage.xml.zip
3. I'll open up the CDash server and drop some logs in another comment if I see anything useful

[tamuseanmiller]

So I'm not seeing any cdash.log file in the CDash/backup directory on the server.

[tamuseanmiller]

I'm afraid this issue has gone stale. Any ideas @zackgalbreath ?

[zackgalbreath]

Thanks for the example. I tested it out locally. It did help me catch a recent regression (addressed in #1433) but otherwise the file parsed cleanly for me.

We're hoping to release CDash 3.2 in a couple weeks. Perhaps we can revisit this issue again to see if it's still a problem for you?

Interesting, I wouldn't even know how to repro this issue for you as I can still upload other info to the server. For example, I can call the Experimental target from include(CTest) from cmake and it will work on a couple generators. We're using that as placeholder for the moment but we really want the ability to customize it how you would with a dashboard script.

I'll wait for the 3.2 release and update when it comes then I'll shoot back here if the issue sticks around.
