Pythonnet crashes .Net application on exit. #245

YMMV but here's some potentially useful feedback on this issue. I'm using OS X 10.11.3 and Anaconda Python (see the specific version in the outputs). Using Mono 4.4.2 I get exactly the same error, even if shrink your code to just this: public static void Main(string[] args)
{
Environment.SetEnvironmentVariable("PYTHONHOME", "/Users/steven/anaconda");
PythonEngine.Initialize();
try
{
using (Py.GIL())
{
dynamic sysModule = Py.Import("sys");
Console.WriteLine("Python engine version:");
Console.WriteLine(sysModule.version);
}
}
finally
{
PythonEngine.Shutdown();
}
}The error is the following: Python engine version:
2.7.12 |Anaconda 4.1.1 (x86_64)| (default, Jul 2 2016, 17:43:17)
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)]

...After upgrading to a newer version of Mono (4.6.1) I get a slightly different error description but I suspect deep down the problem remains the same: Python engine version:

@royalstream @dmitriyse these issues with finalizer were reported recently in Mono: https://bugzilla.xamarin.com/show_bug.cgi?id=41833 Few potential fixes have been made and also workarounds suggested, so have a look there. But your second issue with WAIT_TIMEOUT is not fixed yet in Mono: https://bugzilla.xamarin.com/show_bug.cgi?id=44355 If you open a new issue in Mono, then please link it here. Can you also try explicitly disposing module like mentioned here: |
|
With mono 4.2.4.4 and python 2.7: I'm getting this error: |
|
Now I'm getting the same error on a different machine but without using Dynamic Objects. For the time being I added |
|
@royalstream @dmitriyse can you guys try acquiring the GIL without using |
|
And how do you do that? sorry for the "noob" question but all the code examples I've seen call |
|
I am using this patched version of Runtime.Shutdown() method: internal static void Shutdown()
{
// This workaround reduces risk of Mono or Linux crash.
// Problem probably will be fixed in mono 4.6
if (Path.DirectorySeparatorChar == '/' || Type.GetType("Mono.Runtime") != null)
{
Runtime.Py_Main(3, new[] { "/some.exe", "-c", "exit" });
}
else
{
// else
// Program will crash if we will try to do this under Windows.
//// Runtime.Py_Main(3, new[] { "/some.exe", "-c", "exit" });
}
AssemblyManager.Shutdown();
Exceptions.Shutdown();
ImportHook.Shutdown();
Py_Finalize();
}And this problem gone. So I am assuming that bug exists in PythonNet. P.S to use this workaround in UCS4 builds you should apply also apply this patch: |
|
As i understand, PY_DEGUB build should be used to ensure valid reference counting, indexes access and so on. I tried to build and run PythonNet with this flag and received violations near in every place. I think that PythonNet in general requires big "Cleanup", and probably this problem will disappear. |
|
@royalstream you could have a look at source code of Here is a quick example: |
@dmitriyse I always thought that PY_DEGUB is only helpful for debugging purposes of CPython interpreter, because it produces debug build of CPython? https://docs.python.org/3/c-api/intro.html#debugging-builds But let's open a separate issue for Py_DEBUG failures. |
Sorry for the misunderstanding, I thought you meant avoiding
Now I get a really bad malloc/free error, at least on the machine I'm using right now. I'll try this on a different machine next week. I'm using Mono 4.6.0 (Stable 4.6.0.245/746756c Mon Sep 19 13:57:55 BST 2016) |
|
Looks like you missed this patch. P.S to use this workaround in UCS4 builds you should apply also apply this patch: Also you can check binary distro: https://github.com/dmitriyse/pythonnet/releases/tag/v2.2.0-bin-RC |
|
I didn't miss it but it looks like it doesn't apply to my current Python 2.7 installation (which seems to be UCS2): >>> import sys
>>> print sys.maxunicode

|
UPDATE: I installed the Python 3.5 version of Anaconda (which is UCS4) and the patch works great, no more crashes. PS: If I run the unpatched version of Pythonnet I get a SIGSEGV so the patch is definitely helping. |
|
@dmitriyse @royalstream how are you able to embed Anaconda's CPython using pythonnet on Linux? I tried the following and it is failing with |
|
probably you need to add "CONDA HOME"\lib to LD_LIBRARY_PATH. Or create symlink from "CONDA HOME"\lib\libpython3.5m.so to <python.runtime.dll location>\libpython3.5m.so |
|
@dmitriyse do you mean to add \lib to search path of |
|
@dmitriyse creating symlink did not resolve this. adding the libpython path to $LD_LIBRARY_PATH did not resolve the issue either. |

Optional since NUnit 2.5 https://nunit.org/index.php?p=testFixture&r=2.6.4 * Fix conda build log stderr->stdout Recent conda-build update added a new log output to log:info. Powershell interprets this as an ERROR since its on STDERR. Prevent accidental auto-update & display INFO before building. Would have made debugging this psudo-error easier. * Quiet AppVeyor pip/nuget installs Reduce verbosity to make relevant information easier to find. Errors and Warnings are still displayed. Travis doesn't need this since they have log folding. * Allow private env:var to force conda build To trigger conda build, just add/update private env:vars FORCE_CONDA_BUILD on link below.

Any time the csproj is update (new test for example) it splits them. Splitting them now to not worry about them when reviewing pull_requests. * Update CHANGELOG * Fix PythonException GC (pythonnet#400) Since PythonException doesn't inherit from PyObject, need to reapply the same fix as from gh:365. Seen mostly on PY27/Travis on PyTuple tests. Enable PyTuple tests for PY27/Travis * Add Eval(...) and Exec(...) * Keep RunString Public. Fix Assert.AreEqual order - Deprecation/Removal should be a separate issue/pr - In NUnit/XUnit, expected is the first argument, actual is second. Opposite to how Python does it * Update CHANGELOG * Clarify MashalAs on runtime.cs - Shorten MarshalAsAttribute name - Put MashalAs'ed argument on own-line - Flip IF comparison * Fix runtime Initialize dll nameclash Looks like dllLocal never changes from IntPtr.Zero * Update test_sysargv Previous version didn't test correctly * Fix the issue of sys.argv being cleared on import clr. Closes pythonnet#404. * improve tests.pyproj for intellisense and running tests (pythonnet#395) * Update tests.pyproj * Update folder structure After pytest folders were flatten. Add code in fixture Upstream PyImportTest was moved to within Embedded Tests Add pyproj to editorconfig * Add case-sensitivity tests closes #81 * Added branching for ldd command in OSX (pythonnet#406) * Minor style clean-up runtime/pythonengine Add missing brackets Organize using/remove unused Align arguments * Fix Py_Main/PySys_SetArgvEx(...) UCS4/PY3 no mem Based on @dmitriyse work on: dmitriyse@8a70f09 * Update CHANGELOG, remove extra MarshalAs * Move PythonBuildDir when not defined Keep root of solution clean and out of the way from being imported because its on the `cwd`. * Update ARCH check Use sys for x86/x64 check * Enable TestPyTupleInvalidAppend test `AppDomain unload` was solved by pythonnet#400.

If we embed Python.Net into DotNet application, it crashes on Linux.
Crash occurs when application exits.
This is sample of code that produces crash.
Also it contains 'probably workaround".
Console output :
I tried everything - python 2.7, python 3.5, Mono 4.2, 4.4.
It does not matter, behavior always the same.
Also i tried to build with Py_DEBUG under linux (and pass python library from python3.5-dbg package)
I receive assertions on PythonEngine.Init:
