We've been plagued by seg faults on Linux in the System.Drawing.Common tests, e.g. this one on SUSE:

This has been happening frequently for months, but I can't find an existing issue for it.

Tonight was the night I planned to launch an issue for this. It seems a constant source of outerloop failures. And causes me untold annoyance and investigation ... :) fix or disable I say ;)

Unfortunately Dumpling isn't finding dumps on SUSE. @DrewScoggins have you had a chance ot take a look?
We need a dumpling upload from another distro.

@qmfrederik do you have any context on these segfaults? I'm not sure whether they're only on SUSE, but perhaps it has an outdated copy of libgdiplus (it doesn't return false from GetRecentGdiPlusIsAvailable())

@danmosemsft I don't have any immediate context for these segfaults.

Debian Jessie ships with version 4.2 of libgdiplus which dates from December 2015. There have been a few fixes to libdiplus since.

We'll probably need to do some work to identify all the areas where the corefx CI process identifies areas of libgdiplus which are not stable, and then decide how to deal with that; a couple of options include:

  • Do nothing and let the end users discover the issues one by one
  • Fix the issues in libgdiplus, and require that you use System.Drawing.Common with a recent version of libgdiplus
  • Proactively throw PNSE's in System.Drawing.Common on Unix on areas where we know libgdiplus to be unstable.

Meanwhile, I've downloaded the dumpling but not entirely sure what I'm looking at. Is there a way to extract the managed and native stack traces from those dumpling files?

Is it possible to disable these tests on these platforms and tag them with this issue in the meantime then?

It sounds like a fix isn't a quick thing and they cause a lot of outerloop failures.

@qmfrederik qmfrederik commented Oct 11, 2017

@Drawaes Part of the problem is that for tests that cause the test process to crash (e.g. segfaults), there is no clear indication in the test logs which unit test caused the segfault - so it's not easy to say which test should be disabled (other than disabling all System.Drawing.Common tests all together).

Process of elimination then... you are on a binary search.

Remove 1 test on 1 distro that fails a lot. See if it starts passing, Keep going until that distro either has no tests left or passes. Once it passes go back and try to add the other tests and see if it all works. :)

At least you can narrow it hopefully, and secondly everyone else doesn't have to go into every outerloop because they always fail due to System.Drawing.

Finally, we’ve got a dump, yay! @qmfrederik I sword of know how to open it, so I will try it in my Ubuntu box and update the thread. I think there is a doc if you want to try opening it in your end also. Let me find it an I’ll post it here.

From the dumpling that @danmosemsft pointed out to I got this stack trace:

00007FDBFAAAF990 00007FDC2266A868 DomainBoundILStubClass.IL_STUB_PInvoke(IntPtr, IntPtr, Int32, Int32, Int32, Int32)
00007FDBFAAAFA30 00007FDC22807339 System.Drawing.SafeNativeMethods+Gdip.GdipDrawRectangleI(IntPtr, IntPtr, Int32, Int32, Int32, Int32)
00007FDBFAAAFA80 00007FDC2280726A System.Drawing.Graphics.DrawRectangle(System.Drawing.Pen, Int32, Int32, Int32, Int32)
00007FDBFAAAFAA0 00007FDC228071EB System.Drawing.Graphics.DrawRectangle(System.Drawing.Pen, System.Drawing.Rectangle)
00007FDBFAAAFAD0 00007FDC22802807 System.Drawing.Tests.RegionTests.Complement_GraphicsPathWithMultipleRectangles_Success()

Which points us to the test that crashed and the path that it followed to cause the crash. Will go ahead and take a look at other dumps (if there are) in the other build failures to see if there is other crashing test, and then I'll disable the crashing tests.

In the meantime, @qmfrederik would you mind taking a look at why this is crashing?

Here are the docs on how to load the dump: https://github.com/dotnet/coreclr/blob/master/Documentation/building/debugging-instructions.md#debugging-core-dumps-with-lldb

Let me know if I can help you.

I can't see the failure anymore as the build was reseted. I will try to find the dump in dumpling website and investigate which test is the one that crashed.

@ViktorHofer If (my interpretation of) the Linux stack trace is correct, you are using a version of libgdiplus which contains an embedded copy of cairo. The embedded copy of cairo was removed from libgdiplus in 2014 (via mono/libgdiplus#18).

So it looks like you're using a 4-year old version of libgdiplus. Time to upgrade!

Some thoughts:

  • The Mono repositories at https://download.mono-project.com/repo/ contain libgdiplus 6.0. At the very least, I'd recommend installing libgdiplus 6 on all build servers. Quite some bugs have been fixed in that version.
  • Newer versions of libgdiplus expose version information. (See mono/libgdiplus#84). Do you think it would make sense to have System.Drawing check for this version, and throw an exception of a too old version of libgdiplus is installed?
  • This makes me wonder - would it be worth writing some documentation recommending folks to use a recent version of libgdiplus (perhaps by pointing them to the Mono package repository)?
  • In the past, we had a possibility of using versions of libgdiplus which shipped in NuGet packages. Do you think it makes sense to use that approach for the build servers? It would make it much easier to fix something in libgdiplus, create a NuGet package which contains an updated version of libgdiplus, and use that updated version in corefx, without having to ask the infra team to do work.

@qmfrederik is right. The crash looks like an ancient version of libgdiplus. The Mono CI machines run on version 6.0.4 right now.

Just to make sure, are you commenting on the my last post that lists a macOS crash or the post before which is about Linux-Release-SLES?

In the past, we had a possibility of using versions of libgdiplus which shipped in NuGet packages. Do you think it makes sense to use that approach for the build servers? It would make it much easier to fix something in libgdiplus, create a NuGet package which contains an updated version of libgdiplus, and use that updated version in corefx, without having to ask the infra team to do work.

YES, that would save us and the infra team a lot of trouble.

Yes, that would be good. We could check for a minimum installed version. Do you mind submitting a PR for that?

cc @richlander for the libgdiplus documentation question.

The Linux-Release-SLES is ancient libgdiplus for sure. Haven't looked at the macOS crash yet.

Let me give that a try. I'll also check whether the libgdiplus-from-NuGet approach still works. May take a couple of days. Ping me if I haven't got round to doing it by next week 😄. If someone else can do it faster, feel free to do so 😄 .
