This fixes the TestCheckSupportMatrix failure on Windows, which was caused by Git converting LF to CRLF on Windows, breaking the byte-level comparison between the generated and committed SUPPORT_MATRIX.md file. The test passes on Linux because line endings remain as LF, but fails on Windows where Git may convert them to CRLF during checkout. By explicitly setting eol=lf for text files, we ensure consistent behavior across all platforms. --- .gitattributes | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 .gitattributes diff --git a/.gitattributes b/.gitattributes new file mode 100644 index 00000000..76acfc00 --- /dev/null +++ b/.gitattributes @@ -0,0 +1,23 @@ +# Ensure all text files use LF line endings in the repository +* text=auto + +# Explicitly set LF for specific files that are checked in tests +*.go text eol=lf +*.md text eol=lf +*.sh text eol=lf +*.py text eol=lf +*.yml text eol=lf +*.yaml text eol=lf +*.json text eol=lf +*.txt text eol=lf + +# Binary files +*.png binary +*.jpg binary +*.jpeg binary +*.gif binary +*.so binary +*.pyd binary +*.dll binary +*.exe binary +*.pyc binary From 9234e3281c3fc80661c2987781cdf7a4c58f856e Mon Sep 17 00:00:00 2001 From: b-long Date: Mon, 26 Jan 2026 20:30:12 -0500 Subject: [PATCH 72/77] Update CI configuration to include Windows --- .github/workflows/ci.yml | 34 ++++++++++++++++++++++++++++++---- _examples/cstrings/test.py | 26 ++++++++++++++++++++------ 2 files changed, 50 insertions(+), 10 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 546c1d78..d90e7982 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -20,10 +20,19 @@ jobs: build: name: Build strategy: + fail-fast: false matrix: - go-version: [1.25.x, 1.24.x, 1.22.x, 1.21.x] - platform: [ubuntu-latest] - #platform: [ubuntu-latest, macos-latest, windows-latest] + include: + - go-version: 1.25.x + platform: ubuntu-latest + - go-version: 1.24.x + platform: ubuntu-latest + - go-version: 1.22.x + platform: ubuntu-latest + - go-version: 1.21.x + platform: ubuntu-latest + - go-version: 1.25.x + platform: windows-latest runs-on: ${{ matrix.platform }} steps: - name: Checkout code @@ -50,7 +59,15 @@ jobs: # install goimports go install golang.org/x/tools/cmd/goimports@latest - + - name: Install Windows packages + if: matrix.platform == 'windows-latest' + run: | + # install pybindgen and psutil (for memory tracking in tests) + python -m pip install -U pybindgen psutil + # install goimports + go install golang.org/x/tools/cmd/goimports@latest + + - name: Build-Linux if: matrix.platform == 'ubuntu-latest' run: | @@ -59,6 +76,15 @@ jobs: if: matrix.platform == 'ubuntu-latest' run: | make test + + - name: Build-Windows + if: matrix.platform == 'windows-latest' + run: | + go build -v ./... + - name: Test Windows + if: matrix.platform == 'windows-latest' + run: | + go test -v ./... - name: Upload-Coverage if: matrix.platform == 'ubuntu-latest' uses: codecov/codecov-action@v4 diff --git a/_examples/cstrings/test.py b/_examples/cstrings/test.py index d7b8a830..74def9ce 100644 --- a/_examples/cstrings/test.py +++ b/_examples/cstrings/test.py @@ -7,7 +7,16 @@ import cstrings import gc -import resource +import sys + +# resource module is Unix-only, not available on Windows +# On Windows, use psutil for memory tracking +if sys.platform == 'win32': + import psutil + HAS_RESOURCE = False +else: + import resource + HAS_RESOURCE = True verbose = False iterations = 10000 @@ -39,7 +48,11 @@ def gofnMap(): def print_memory(s): - m = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss + if HAS_RESOURCE: + m = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss + else: + # psutil returns memory in bytes, convert to KB to match resource module + m = psutil.Process().memory_info().rss // 1024 if verbose: print(s, m) return m @@ -69,17 +82,18 @@ def _run_fn(fn): for fn in [gofnString, gofnStruct, gofnNestedStruct, gofnSlice, gofnMap]: alloced = size * iterations - a = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss + a = print_memory("Initial memory:") pass1 = _run_fn(fn) - b = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss + b = print_memory("After first pass:") pass2 = _run_fn(fn) - c = resource.getrusage(resource.RUSAGE_SELF).ru_maxrss + c = print_memory("After second pass:") if verbose: print(fn.__name__, pass1) print(fn.__name__, pass2) print(fn.__name__, a, b, c) - print(fn.__name__, "leaked: ", (c-b) > (size * iterations)) + leaked = (c-b) > (size * iterations) + print(fn.__name__, "leaked: ", leaked) # bump up the size of each successive test to ensure that leaks # are not absorbed by previous rss growth.

C string leak in generated getters. When reading a string field from a Go struct, slice, or map, the generated code allocated a C string with C.CString() but never freed it. Over thousands of calls this accumulated enough memory to exceed the leak threshold in TestCStrings. Fixed by switching those accessors to use add_checked_string_function, which adds the missing free() after the Python string is built. 2. Unsafe Go GC call from a CGo thread. The generated wrapper called runtime.GC() directly while Python's garbage collector was running, which could panic with "bad sweepgen in refill" on multi-core machines. Fixed by routing the GC call through a background goroutine via a channel, so it always runs on a proper Go thread. 3. Go GC and Python GC out of sync. Without any coordination, Go heap objects could pile up between Python GC cycles, causing RSS to grow across test passes. The generated wrapper now registers a Python gc.callbacks handler that triggers a Go GC cycle after each Python GC cycle, keeping the two runtimes in sync automatically. 4. Symbol interposition between co-loaded extensions. On some platforms, loading two gopy .so files with RTLD_GLOBAL caused Go runtime symbols from one extension to override those in the other, corrupting heap state. Fixed by loading extensions without RTLD_GLOBAL and clearing the Go TLS slot before each CGo entry so each extension uses its own runtime context. Also adds macos-15 (ARM) and macos-15-intel to the CI matrix, and includes a new gilstring regression test that exercises two extensions in one process. * ci: remove macos-15-intel from support matrix * ci: add golang 1.23.x to support matrix * run 'go mod tidy' * fix: match minimum supported go version 1.22.x See also: https://github.com/go-python/gopy/issues/387 --------- Co-authored-by: Ben Carver --- .github/workflows/ci.yml | 21 +++++++-- SUPPORT_MATRIX.md | 1 + _examples/cgo/cgo.go | 2 +- _examples/gilstring/gilstring.go | 14 ++++++ _examples/gilstring/test.py | 18 ++++++++ bind/gen.go | 78 ++++++++++++++++++++++++++++++++ bind/gen_func.go | 9 ++-- bind/gen_map.go | 6 ++- bind/gen_slice.go | 6 ++- bind/gen_struct.go | 6 ++- bind/symbols.go | 16 +++++-- cmd_build.go | 53 ++++++++++++++++++---- main_test.go | 72 +++++++++++++++++++++++++++-- 13 files changed, 277 insertions(+), 25 deletions(-) create mode 100644 _examples/gilstring/gilstring.go create mode 100644 _examples/gilstring/test.py diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index e232aa0c..ada2439c 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -22,9 +22,9 @@ jobs: strategy: fail-fast: false matrix: - go-version: [1.25.x, 1.24.x, 1.22.x, 1.21.x] - platform: [ubuntu-latest, windows-latest] - #platform: [ubuntu-latest, macos-latest, windows-latest] + # TODO: Consider official support matrix (OS and Go versions) and adjust this matrix accordingly + go-version: [1.25.x, 1.24.x, 1.23.x, 1.22.x] + platform: [ubuntu-latest, windows-latest, macos-15] runs-on: ${{ matrix.platform }} steps: - name: Checkout code @@ -51,6 +51,12 @@ jobs: # install goimports go install golang.org/x/tools/cmd/goimports@latest + - name: Install macOS packages + if: startsWith(matrix.platform, 'macos-') + run: | + python3 -m pip install -U pybindgen + go install golang.org/x/tools/cmd/goimports@latest + - name: Install Windows packages if: matrix.platform == 'windows-latest' run: | @@ -69,6 +75,15 @@ jobs: run: | make test + - name: Build-macOS + if: startsWith(matrix.platform, 'macos-') + run: | + make + - name: Test macOS + if: startsWith(matrix.platform, 'macos-') + run: | + make test + - name: Build-Windows if: matrix.platform == 'windows-latest' run: | diff --git a/SUPPORT_MATRIX.md b/SUPPORT_MATRIX.md index 8e73c1ae..8f30be77 100644 --- a/SUPPORT_MATRIX.md +++ b/SUPPORT_MATRIX.md @@ -11,6 +11,7 @@ _examples/consts | yes _examples/cstrings | yes _examples/empty | yes _examples/funcs | yes +_examples/gilstring | yes _examples/gobytes | yes _examples/gopygc | yes _examples/gostrings | yes diff --git a/_examples/cgo/cgo.go b/_examples/cgo/cgo.go index 98a64a31..4119d47a 100644 --- a/_examples/cgo/cgo.go +++ b/_examples/cgo/cgo.go @@ -9,7 +9,7 @@ package cgo //#include //#include //const char* cpkg_sprintf(const char *str) { -// char *o = (char*)malloc(strlen(str)); +// char *o = (char*)malloc(strlen(str) + 1); // sprintf(o, "%s", str); // return o; //} diff --git a/_examples/gilstring/gilstring.go b/_examples/gilstring/gilstring.go new file mode 100644 index 00000000..9410c57a --- /dev/null +++ b/_examples/gilstring/gilstring.go @@ -0,0 +1,14 @@ +// Copyright 2026 The go-python Authors.
