From 5c4b0d063aba0a68c325073f5f312a2c9f40d178 Mon Sep 17 00:00:00 2001 From: Ned Deily Date: Sat, 4 Mar 2017 00:19:55 -0500 Subject: bpo-27593: Get SCM build info from git instead of hg. (#446) sys.version and the platform module python_build(), python_branch(), and python_revision() functions now use git information rather than hg when building from a repo. Based on original patches by Brett Cannon and Steve Dower. --- Include/pylifecycle.h | 4 ++-- Lib/platform.py | 4 +++- Lib/test/test_platform.py | 12 ++++++------ Makefile.pre.in | 12 ++++++------ Misc/NEWS | 4 ++++ Modules/getbuildinfo.c | 46 ++++++++++++++++++++++----------------------- Python/sysmodule.c | 6 +++--- configure | 48 +++++++++++++++++++++++------------------------ configure.ac | 26 ++++++++++++------------- 9 files changed, 84 insertions(+), 78 deletions(-) diff --git a/Include/pylifecycle.h b/Include/pylifecycle.h index 5a67666..01abfa9 100644 --- a/Include/pylifecycle.h +++ b/Include/pylifecycle.h @@ -70,8 +70,8 @@ PyAPI_FUNC(const char *) Py_GetCopyright(void); PyAPI_FUNC(const char *) Py_GetCompiler(void); PyAPI_FUNC(const char *) Py_GetBuildInfo(void); #ifndef Py_LIMITED_API -PyAPI_FUNC(const char *) _Py_hgidentifier(void); -PyAPI_FUNC(const char *) _Py_hgversion(void); +PyAPI_FUNC(const char *) _Py_gitidentifier(void); +PyAPI_FUNC(const char *) _Py_gitversion(void); #endif /* Internal -- various one-time initializations */ diff --git a/Lib/platform.py b/Lib/platform.py index 0623475..cc2db98 100755 --- a/Lib/platform.py +++ b/Lib/platform.py @@ -1198,7 +1198,9 @@ def _sys_version(sys_version=None): elif buildtime: builddate = builddate + ' ' + buildtime - if hasattr(sys, '_mercurial'): + if hasattr(sys, '_git'): + _, branch, revision = sys._git + elif hasattr(sys, '_mercurial'): _, branch, revision = sys._mercurial elif hasattr(sys, 'subversion'): # sys.subversion was added in Python 2.5 diff --git a/Lib/test/test_platform.py b/Lib/test/test_platform.py index 5f875ef..ea6752b 100644 --- a/Lib/test/test_platform.py +++ b/Lib/test/test_platform.py @@ -67,12 +67,12 @@ class PlatformTest(unittest.TestCase): def setUp(self): self.save_version = sys.version - self.save_mercurial = sys._mercurial + self.save_git = sys._git self.save_platform = sys.platform def tearDown(self): sys.version = self.save_version - sys._mercurial = self.save_mercurial + sys._git = self.save_git sys.platform = self.save_platform def test_sys_version(self): @@ -102,7 +102,7 @@ class PlatformTest(unittest.TestCase): ('CPython', '2.4.3', '', '', 'truncation', '', 'GCC')), ): # branch and revision are not "parsed", but fetched - # from sys._mercurial.
