classes would help to manage codec layers. For example, a library could register its own codecs, but also allow anyone to inject their codecs before library's own: public static EncoderGroup BeforeLibraryEncoders { get; } = new EncoderGroup(); void LibraryRegisterCodecs(){ PyObjectConversions.RegisterEncoder(BeforeLibraryEncoders); PyObjectConversions.RegisterEncoder(LibraryEncoder.Instance); } Then in a program using that library: Library.BeforeLibraryEncoders.Encoders.Add(preencoder);

A C# object `a` is created and filled with some data. 2. `a` is passed via Python.NET to Python. To do that Python.NET creates a wrapper object `w`, and stores reference to `a` in one of its fields. 3. Python code later passes `w` back to C#, e.g. calls `SomeCSharpMethod(w)`. 4. Python.NET has to unwrap `w`, so it reads the reference to `a` from it. Prior to this change in 4. Python.NET had to determine what kind of an object `a` is. If it is an exception, a different offset needed to be used. That check was very expensive (up to 4 calls into Python interpreter). This change replaces that check with computing offset unconditionally by subtracting a constant from the object size (which is read from the wrapper), thus avoiding calls to Python interpreter.

At deserialization, use reflection to attempt to recreate the object, which may fail safely instead of throwing a SerializaitonException during the deserialization of the whoie data stream. Appropriate Exceptions will now be raised when the Maybe*'s Value property. ClassBase objects are now de-initialized and re-initialized in Reload mode so that it's tp_dict picks up newly added members and removed members no longer linger. ModuleObject clears it's cache and remove cached members from it's tp_dict. Minor refactoring and modernization of MethodObject and MethodBinder * Call PyType_Modified after modifying the type Changing a type's attribute causes problem with it's cache. Force the type to refresh itself when modifying it. * Refactor the member binding logic of ClassManager So that we can use that same logic when deserializing Maybe* types * Include info about why deserialization failed in Maybe* * Remove TestClassReference The test case is covered in test_domain_relaod Co-authored-by: Benedikt Reinartz Co-authored-by: Victor Milovanov --- pythonnet.sln | 14 +

Apart from dropping the respective old code, this requires the following changes: - Move libpython discovery into Python by vendoring and adjusting `find_libpython` - Adjust the GIL handling in the startup code as CFFI releases the GIL when calling the external function - Remove the intermittent `configure` command as it is not required anymore - Adjust a few test-cases - Remove `_AtExit` Due to issues with the reference counts, the `atexit` callback is currently essentially a no-op until these are fixed. --- .github/workflows/main.yml | 53 +-- .gitignore | 3 - Directory.Build.props | 1 - appveyor.yml | 3 +- clr.py | 39 +- pythonnet.sln | 2 - pythonnet/__init__.py | 74 +++- pythonnet/find_libpython/__init__.py | 399 ++++++++++++++++++++ pythonnet/find_libpython/__main__.py | 2 + pythonnet/mono/.gitkeep | 0 pythonnet/netfx/.gitkeep | 0 pythonnet/util/__init__.py | 1 + requirements.txt | 2 +- setup.py | 125 +------ src/clrmodule/ClrModule.cs | 113 ------ src/clrmodule/Properties/AssemblyInfo.cs | 5 - src/clrmodule/clrmodule.csproj | 24 -- src/embed_tests/TestNativeTypeOffset.cs | 7 +- src/monoclr/clrmod.c | 215 ----------- src/runtime/Python.Runtime.csproj | 3 +- src/runtime/loader.cs | 83 +++++ src/runtime/moduleobject.cs | 6 - src/runtime/native/TypeOffset.cs | 1 - src/runtime/pythonengine.cs | 14 +- src/runtime/runtime.cs | 441 +++++++++++------------ src/tests/test_method.py | 3 - src/tests/test_sysargv.py | 5 +- tools/geninterop/geninterop.py | 4 +- 28 files changed, 804 insertions(+), 824 deletions(-) create mode 100644 pythonnet/find_libpython/__init__.py create mode 100644 pythonnet/find_libpython/__main__.py delete mode 100644 pythonnet/mono/.gitkeep delete mode 100644 pythonnet/netfx/.gitkeep create mode 100644 pythonnet/util/__init__.py delete mode 100644 src/clrmodule/ClrModule.cs delete mode 100644 src/clrmodule/Properties/AssemblyInfo.cs delete mode 100644 src/clrmodule/clrmodule.csproj delete mode 100644 src/monoclr/clrmod.c create mode 100644 src/runtime/loader.cs diff --git a/.github/workflows/main.yml b/.github/workflows/main.yml index 3c8fabcc1..10959ea4f 100644 --- a/.github/workflows/main.yml +++ b/.github/workflows/main.yml @@ -12,33 +12,9 @@ jobs: fail-fast: false matrix: os: [windows, ubuntu, macos] - pyver_minor: [6, 7, 8, 9] + python: ["3.6", "3.7", "3.8", "3.9"] platform: [x64] shutdown_mode: [Normal, Soft] - include: - - os: ubuntu - pyver_minor: 6 - dll_suffix: m - - os: ubuntu - pyver_minor: 7 - dll_suffix: m - - - os: macos - dll_prefix: lib - dll_pyver_major: '3.' - dll_suffix: m - - os: ubuntu - dll_prefix: lib - dll_pyver_major: '3.' - - os: windows - dll_pyver_major: '3' - - - os: ubuntu - dll_ext: .so - - os: windows - dll_ext: .dll - - os: macos - dll_ext: .dylib env: PYTHONNET_SHUTDOWN_MODE: ${{ matrix.SHUTDOWN_MODE }} @@ -56,10 +32,10 @@ jobs: - name: Setup .NET uses: actions/setup-dotnet@v1 - - name: Set up Python 3.${{ matrix.pyver_minor }} + - name: Set up Python ${{ matrix.python }} uses: actions/setup-python@v2 with: - python-version: 3.${{ matrix.pyver_minor }} + python-version: ${{ matrix.python }} architecture: ${{ matrix.platform }} - name: Install dependencies @@ -68,31 +44,26 @@ jobs: - name: Build and Install run: | - python setup.py configure pip install -v . - # TODO this should be gone once clr module sets PythonDLL or preloads it - - name: Python Tests - run: pytest - if: ${{ matrix.os != 'macos' }} - env: - PYTHONNET_PYDLL: ${{ matrix.DLL_PREFIX }}python${{matrix.DLL_PYVER_MAJOR}}${{matrix.PYVER_MINOR}}${{matrix.DLL_SUFFIX}}${{matrix.DLL_EXT}} + - name: Set Python DLL path (non Windows) + if: ${{ matrix.os != 'windows' }} + run: | + python -m pythonnet.find_libpython --export >> $GITHUB_ENV + - name: Set Python DLL path (Windows) + if: ${{ matrix.os == 'windows' }} + run: | + python -m pythonnet.find_libpython --export | Out-File -FilePath $env:GITHUB_ENV -Encoding utf8 -Append + - name: Python Tests run: pytest - if: ${{ matrix.os == 'macos' }} - name: Embedding tests run: dotnet test --runtime any-${{ matrix.platform }} src/embed_tests/ - if: ${{ matrix.os != 'macos' }} # Not working right now, doesn't find libpython - env: - PYTHONNET_PYDLL: ${{ matrix.DLL_PREFIX }}python${{matrix.DLL_PYVER_MAJOR}}${{matrix.PYVER_MINOR}}${{matrix.DLL_SUFFIX}}${{matrix.DLL_EXT}} - name: Python tests run from .NET run: dotnet test --runtime any-${{ matrix.platform }} src/python_tests_runner/ - if: ${{ matrix.os == 'windows' }} # Not working for others right now - env: - PYTHONNET_PYDLL: ${{ matrix.DLL_PREFIX }}python${{matrix.DLL_PYVER_MAJOR}}${{matrix.PYVER_MINOR}}${{matrix.DLL_SUFFIX}}${{matrix.DLL_EXT}} # TODO: Run perf tests # TODO: Run mono tests on Windows?

You can still dispose `.Type`, `.Value` and `.Traceback`, but it is not recommended, as they may be shared with other instances. --- CHANGELOG.md | 2 + src/embed_tests/Codecs.cs | 44 ++-- src/embed_tests/TestCallbacks.cs | 2 +- src/embed_tests/TestPyFloat.cs | 4 +- src/embed_tests/TestPyInt.cs | 4 +- src/embed_tests/TestPyList.cs | 2 +- src/embed_tests/TestPyLong.cs | 4 +- src/embed_tests/TestPyTuple.cs | 4 +- src/embed_tests/TestPyType.cs | 1 + src/embed_tests/TestPyWith.cs | 2 +- src/embed_tests/TestPythonException.cs | 64 +++-- src/embed_tests/pyimport.cs | 3 +- src/embed_tests/pyinitialize.cs | 2 +- src/runtime/StolenReference.cs | 34 ++- src/runtime/classmanager.cs | 2 +- src/runtime/converter.cs | 3 + src/runtime/delegatemanager.cs | 10 +- src/runtime/exceptions.cs | 67 +++-- src/runtime/finalizer.cs | 2 +- src/runtime/importhook.cs | 4 +- src/runtime/methodbinder.cs | 2 +- src/runtime/moduleobject.cs | 4 +- src/runtime/pybuffer.cs | 8 +- src/runtime/pyiter.cs | 2 +- src/runtime/pyobject.cs | 28 ++- src/runtime/pythonengine.cs | 18 +- src/runtime/pythonexception.cs | 324 ++++++++++++------------- src/runtime/pytuple.cs | 2 +- src/runtime/pytype.cs | 34 +++ src/runtime/runtime.cs | 55 +++-- src/runtime/typemanager.cs | 12 +- 31 files changed, 415 insertions(+), 334 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 3081e2e84..5871e7ffb 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -49,6 +49,7 @@ One must now either use enum members (e.g. `MyEnum.Option`), or use enum constru support for .NET Core - .NET and Python exceptions are preserved when crossing Python/.NET boundary - BREAKING: custom encoders are no longer called for instances of `System.Type` +- `PythonException.Restore` no longer clears `PythonException` instance. ### Fixed @@ -74,6 +75,7 @@ One must now either use enum members (e.g. `MyEnum.Option`), or use enum constru ### Removed - implicit assembly loading (you have to explicitly `clr.AddReference` before doing import) +- messages in `PythonException` no longer start with exception type - support for .NET Framework 4.0-4.6; Mono before 5.4.

nint tp_clr_inst_offset; GCHandel tp_clr_inst; (points, for example, to an instance of `ClassObject`) When a Python type, that reflects CLR type is created, the layout of instances will be: BaseTypeFields base; optional (if not in base): IntPtr dict; optional (if not in base): IntPtr weaklist; GCHandle gcHandle; (points to `CLRObject` instance, which in turn, for example, points to the actual instance of `System.Uri`) The offset to GC handle is recorded in the Python type's `tp_clr_inst_offset`, and can be found as `PyObject_Type(inst).tp_clr_inst_offset`. Or, preferably, accessor functions in `ManagedType` should be used. --- src/embed_tests/TestPyType.cs | 3 +- src/runtime/classbase.cs | 17 +- src/runtime/classderived.cs | 12 +- src/runtime/clrobject.cs | 23 +-- src/runtime/converter.cs | 6 +- src/runtime/exceptions.cs | 16 +- src/runtime/extensiontype.cs | 6 +- src/runtime/importhook.cs | 28 +-- src/runtime/interop.cs | 272 +---------------------------- src/runtime/managedtype.cs | 108 +++++++++--- src/runtime/metatype.cs | 27 ++- src/runtime/moduleobject.cs | 8 +- src/runtime/native/ABI.cs | 3 - src/runtime/native/ITypeOffsets.cs | 1 + src/runtime/native/TypeOffset.cs | 10 +- src/runtime/runtime.cs | 29 +-- src/runtime/runtime_data.cs | 2 +- src/runtime/typemanager.cs | 195 ++++++++++----------- 18 files changed, 264 insertions(+), 502 deletions(-) diff --git a/src/embed_tests/TestPyType.cs b/src/embed_tests/TestPyType.cs index 02142b782..f70a54c99 100644 --- a/src/embed_tests/TestPyType.cs +++ b/src/embed_tests/TestPyType.cs @@ -1,3 +1,4 @@ +using System.Runtime.InteropServices; using System.Text; using NUnit.Framework; @@ -30,7 +31,7 @@ public void CanCreateHeapType() using var doc = new StrPtr(docStr, Encoding.UTF8); var spec = new TypeSpec( name: name, - basicSize: ObjectOffset.Size(Runtime.Runtime.PyTypeType), + basicSize: Marshal.ReadInt32(Runtime.Runtime.PyBaseObjectType, TypeOffset.tp_basicsize), slots: new TypeSpec.Slot[] { new (TypeSlotID.tp_doc, doc.RawPointer), }, diff --git a/src/runtime/classbase.cs b/src/runtime/classbase.cs index 8b96a96da..bf6a8034d 100644 --- a/src/runtime/classbase.cs +++ b/src/runtime/classbase.cs @@ -1,9 +1,6 @@ using System; using System.Collections; using System.Collections.Generic; -using System.Diagnostics; -using System.Runtime.InteropServices; -using System.Runtime.Serialization; namespace Python.Runtime { @@ -355,19 +352,21 @@ public static void tp_dealloc(IntPtr ob) { ManagedType self = GetManagedObject(ob); tp_clear(ob); - Runtime.PyObject_GC_UnTrack(self.pyHandle); - Runtime.PyObject_GC_Del(self.pyHandle); - self.FreeGCHandle(); + Runtime.PyObject_GC_UnTrack(ob); + Runtime.PyObject_GC_Del(ob); + self?.FreeGCHandle(); } public static int tp_clear(IntPtr ob) { ManagedType self = GetManagedObject(ob); - if (!self.IsTypeObject()) + + bool isTypeObject = Runtime.PyObject_TYPE(ob) == Runtime.PyCLRMetaType; + if (!isTypeObject) { ClearObjectDict(ob); } - self.tpHandle = IntPtr.Zero; + if (self is not null) self.tpHandle = IntPtr.Zero; return 0; } @@ -391,7 +390,7 @@ protected override void OnLoad(InterDomainContext context) SetObjectDict(pyHandle, dict); } gcHandle = AllocGCHandle(); - Marshal.WriteIntPtr(pyHandle, TypeOffset.magic(), (IntPtr)gcHandle); + SetGCHandle(ObjectReference, gcHandle); } diff --git a/src/runtime/classderived.cs b/src/runtime/classderived.cs index 4e8e88bf3..8b15213c3 100644 --- a/src/runtime/classderived.cs +++ b/src/runtime/classderived.cs @@ -1,5 +1,6 @@ using System; using System.Collections.Generic; +using System.Diagnostics; using System.Linq; using System.Reflection; using System.Reflection.Emit; @@ -75,8 +76,8 @@ internal ClassDerivedObject(Type tp) : base(tp) // So we don't call PyObject_GC_Del here and instead we set the python // reference to a weak reference so that the C# object can be collected.
