Runtime: Seg fault in System.Drawing.Common tests on Unix

[stephentoub]

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.

[Drawaes]

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 ;)

[danmosemsft]

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.

[benaadams]

Related? https://github.com/dotnet/corefx/issues/24538

[danmosemsft]

@benaadams I do'nt think so, that's freebsd specific.

[danmosemsft]

@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 I'm not sure whether they're only on SUSE, but perhaps it has an outdated copy of libgdiplus (it doesn't return false from GetRecentGdiPlusIsAvailable())

/cc @safern

[danmosemsft]

Debian8.7 now.

https://mc.dot.net/#/user/adiaaida/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/52c33af0e09a614ab89ba8b519fc21de0e53bdcf/workItem/System.Drawing.Common.Tests/wilogs

This should have everything needed to debug:
https://dumpling.azurewebsites.net/api/dumplings/archived/eefcb1cc36977ccf86f457ee28a33a7b4cc24e13

[qmfrederik]

@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?

[Drawaes]

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]

@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).

[Drawaes]

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.

[stephentoub]

This one's on Fedora:
https://mc.dot.net/#/user/dotnet-maestro-bot/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/231901a598b4bb3c7591db6b3496a656c92e3644

[stephentoub]

And on CentOS:
https://mc.dot.net/#/user/dotnet-maestro-bot/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/231901a598b4bb3c7591db6b3496a656c92e3644

[safern]

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.

[safern]

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.

[Drawaes]

Thanks that would be awesome

[safern]

PR to disable: https://github.com/dotnet/corefx/pull/24581

In the meantime we can keep investigating and add more test to that PR if needed.

[safern]

Another crash, this one was in OSX.

https://mc.dot.net/#/user/maryamariyan/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/c82555dd4d47101cea779ddd4f5365e7401c95ba/workItem/System.Drawing.Common.Tests/wilogs

@DrewScoggins it failed to upload the dump, there was an exception thrown in Dumpling.py

[DrewScoggins]

Yeah, this is known. I am going to try and look at this today, it's just been a little bit of a pain getting a working Mac.

[stephentoub]

Another one, this time on Ubuntu:
https://mc.dot.net/#/user/dotnet-maestro-bot/pr~2Fjenkins~2Fdotnet~2Fcorefx~2Fmaster~2F/test~2Ffunctional~2Fcli~2F/936049c915e73bee2c3c09209df59ddf465d1e14

[safern]

Another one, this time on Ubuntu:

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.

Unfortunately OSX is not uploading the dumps correctly @DrewScoggins is working on fixing that, and we're still working on being able to crack open a dump in OSX :(

We could add show progress which might suggest which test.

This was redhat. Maybe with this stack trace we are able to figure out what's happening, I would suspect all of them to be related to libgdiplus

@qmfrederik looks like a libgdiplus issue. Would you mind helping to investigate?

@safern Is there a way we can get the latest version of libgdiplus (as in, the git version) on the CI servers? @hughbe has been doing a lot of work on libgdiplus, so just upgrading may already improve the CI stability.

[safern]

@mmitche could you help me update the installed version of libgdiplus in CI and Helix machines?

[mmitche]

@safern This is just a build time dependency that needs updating?

[mmitche]

I am trying to figure out where this needs to be updated. It might just be in the docker container. Can you point me to a build where it needs updating?

@filipnavara FYI, looking at the dump it looks like this fails in GdipGetPathPoints. I know you have a PR open that maybe could fix this.

It would be good to get the path PRs (and the other open pull requests 🙃 ) merged so maybe this problem would be fixed or can be debugged cc @akoeplinger

@safern I changed the milestone to 3.0 as I believe we should investigate further before we release to make sure this doesn't impact customers.

Yes, I think this is happening in libgdiplus. Following offline.

[filipnavara]

Are the core dump files accessible somewhere?

[ViktorHofer]

I don't think we can make the dump easily available externally.

[filipnavara]

I suspect this is just outdated libgdiplus install. Unless you can think of a better way I will make a PR that will fail and dump out the version in an error message.

[safern]

We’ve confirmed offline that RedHat6 agents have a really old instance of libgdiplus and the engineering team is working on updating those guys.

[danmosemsft]

@filipnavara it would be great to have a PR that always logged the libgdiplus version here
https://github.com/dotnet/corefx/blob/008d21c47c22b5757e09f6c3d346998004a0f985/src/System.Runtime.InteropServices.RuntimeInformation/tests/DescriptionNameTests.cs#L42
That way we can easily check if this question comes up in future in whatever test configuration.

[safern]

I've opened: https://github.com/dotnet/corefx/issues/37846

[filipnavara]

Thanks everyone for acting so quickly! Really appreciated :)

Not sure if that error is related: *** glibc detected *** /home/helixbot/work/69be1f2e-c2d7-4316-9991-e7908fdb5cca/Payload/dotnet: double free or corruption (fasttop): 0x00007fc724403430 ***

Again this is in Rehat6 which @mattgal confirmed some machines haven’t yet been completely updated to latest libgdiplus.

https://github.com/dotnet/corefx/pull/38475#issuecomment-501374174

Maybe we should just disable the drawing tests on redhat6 until we can get all the machines on a sane version of libgdiplus. Maybe the easiest way is to add a !IsRedHat6 to our IsGdiPlusAvailable property to skip the tests.

[ViktorHofer]

I'm okay if we just wait until the fix is rolled out on all machines.

[safern]

Moving to future as this is infrastructure dependent on the version of libgdiplus our machines are running on, and from what I know, the only pending machines to be updated are SOME of the RedHat6 ones.

[MattGal]

@safern this should be on every RH6 machine today, if you're seeing the problems still we should reactivate (move to WIP) https://github.com/dotnet/core-eng/issues/6370 with details.

[ViktorHofer]

Let's close this one meanwhile.

[safern]

Re-opening as it just happened again. https://github.com/dotnet/corefx/pull/38635

I just put up a PR to disable the tests on RedHat6: https://github.com/dotnet/corefx/pull/38649

I was able to get a a local repro when running the tests in a loop, it repro every 100 runs aprox. I assigned myself to gather a dump and look at what test is causing it and investigate why.

@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 https://github.com/mono/libgdiplus/pull/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 https://github.com/mono/libgdiplus/pull/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.

[ViktorHofer]

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.

[ViktorHofer]

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?

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

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)?

cc @richlander for the libgdiplus documentation question.

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

[qmfrederik]

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

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 :smile:. If someone else can do it faster, feel free to do so :smile: .

@jkotas unsure if this issue was only tracking rhel6 failures.

[jkotas]

Keeping it open. There are still tests disabled against this issue.

Failed again on macOS.
