Merged revisions 70734,70775,70856,70874,70876-70877 via svnmerge ........ r70734 | r.david.murray | 2009-03-30 15:04:00 -0400 (Mon, 30 Mar 2009) | 7 lines Add import_function method to test.test_support, and modify a number of tests that expect to be skipped if imports fail or functions don't exist to use import_function and import_module. The ultimate goal is to change regrtest to not skip automatically on ImportError. Checking in now to make sure the buldbots don't show any errors on platforms I can't direct test on. ........ r70775 | r.david.murray | 2009-03-30 19:05:48 -0400 (Mon, 30 Mar 2009) | 4 lines Change more tests to use import_module for the modules that should cause tests to be skipped. Also rename import_function to the more descriptive get_attribute and add a docstring. ........ r70856 | r.david.murray | 2009-03-31 14:32:17 -0400 (Tue, 31 Mar 2009) | 7 lines A few more test skips via import_module, and change import_module to return the error message produced by importlib, so that if an import in the package whose import is being wrapped is what failed the skip message will contain the name of that module instead of the name of the wrapped module. Also fixed formatting of some previous comments. ........ r70874 | r.david.murray | 2009-03-31 15:33:15 -0400 (Tue, 31 Mar 2009) | 5 lines Improve test_support.import_module docstring, remove deprecated flag from get_attribute since it isn't likely to do anything useful. ........ r70876 | r.david.murray | 2009-03-31 15:49:15 -0400 (Tue, 31 Mar 2009) | 4 lines Remove the regrtest check that turns any ImportError into a skipped test. Hopefully all modules whose imports legitimately result in a skipped test have been properly wrapped by the previous commits. ........ r70877 | r.david.murray | 2009-03-31 15:57:24 -0400 (Tue, 31 Mar 2009) | 2 lines Add NEWS entry for regrtest change. ........

Without it, sysutils._python_build() returns the wrong directory, which causes the test_get_config_h_filename method in Lib/distutils/tests/test_sysconfig.py to fail. ........ r61613 | trent.nelson | 2008-03-19 08:45:19 +0100 (Mi, 19 Mär 2008) | 3 lines Refine the Visual Studio 2008 build solution in order to improve how we deal with external components, as well as fixing outstanding issues with Windows x64 build support. Introduce two new .vcproj files, _bsddb44.vcproj and sqlite3.vcproj, which replace the previous pre-link event scripts for _bsddb and _sqlite3 respectively. The new project files inherit from our property files as if they were any other Python module. This has numerous benefits. First, the components get built with exactly the same compiler flags and settings as the rest of Python. Second, it makes it much easier to debug problems in the external components when they're part of the build system. Third, they'll benefit from profile guided optimisation in the release builds, just like the rest of Python core. I've also introduced a slightly new pattern for managing externals in subversion. New components get checked in as <name>-<version>.x, where <version> matches the exact vendor version string. After the initial import of the external component, the .x is tagged as .0 (i.e. tcl-8.4.18.x -> tcl-8.4.18.0). Some components may not need any tweaking, whereas there are others that might (tcl/tk fall into this bucket). In that case, the relevant modifications are made to the .x branch, which will be subsequently tagged as .1 (and then n+1 going forward) when they build successfully and all tests pass. Buildbots will be converted to rely on these explicit tags only, which makes it easy for us to switch them over to a new version as and when required. (Simple change to external(-amd64).bat: if we've bumped tcl to 8.4.18.1, change the .bat to rmdir 8.4.18.0 if it exists and check out a new .1 copy.) ........ r61614 | trent.nelson | 2008-03-19 08:56:39 +0100 (Mi, 19 Mär 2008) | 1 line Remove extraneous apostrophe and semi-colon from AdditionalIncludeDirectories. ........ r61615 | georg.brandl | 2008-03-19 08:56:40 +0100 (Mi, 19 Mär 2008) | 2 lines Remove footnote from versionchanged as it upsets LaTeX. ........ r61616 | georg.brandl | 2008-03-19 08:57:57 +0100 (Mi, 19 Mär 2008) | 2 lines Another one. ........ r61618 | trent.nelson | 2008-03-19 09:06:03 +0100 (Mi, 19 Mär 2008) | 1 line Fix the tcl-8.4.18.1 path and make sure we cd into the right directory when building tcl/tk. ........ r61621 | trent.nelson | 2008-03-19 10:23:08 +0100 (Mi, 19 Mär 2008) | 1 line Lets have another try at getting the Windows buildbots in a consistent state before rebuilding using the new process. ........ r61622 | eric.smith | 2008-03-19 13:09:55 +0100 (Mi, 19 Mär 2008) | 2 lines Use test.test_support.captured_stdout instead of a custom contextmanager.

One could use an explicit value for __path__ when making the call to __import__ to force the exact location searched for encodings. This would give the most strict search path possible if one is worried about malicious code being imported. The unfortunate side-effect of that is that if __path__ was modified on 'encodings' on purpose in a safe way it would not be picked up in future __import__ calls. ........ r53801 | brett.cannon | 2007-02-16 20:33:01 +0100 (Fri, 16 Feb 2007) | 2 lines Make the __import__ call in encodings.__init__ absolute with a level 0 call. ........ r53809 | vinay.sajip | 2007-02-16 23:36:24 +0100 (Fri, 16 Feb 2007) | 1 line Minor fix for currentframe (SF #1652788). ........ r53818 | raymond.hettinger | 2007-02-19 03:03:19 +0100 (Mon, 19 Feb 2007) | 3 lines Extend work on revision 52962: Eliminate redundant calls to PyObject_Hash(). ........ r53820 | raymond.hettinger | 2007-02-19 05:08:43 +0100 (Mon, 19 Feb 2007) | 1 line Add merge() function to heapq. ........ r53821 | raymond.hettinger | 2007-02-19 06:28:28 +0100 (Mon, 19 Feb 2007) | 1 line Add tie-breaker count to preserve sort stability. ........ r53822 | raymond.hettinger | 2007-02-19 07:59:32 +0100 (Mon, 19 Feb 2007) | 1 line Use C heapreplace() instead of slower _siftup() in pure python. ........ r53823 | raymond.hettinger | 2007-02-19 08:30:21 +0100 (Mon, 19 Feb 2007) | 1 line Add test for merge stability ........ r53824 | raymond.hettinger | 2007-02-19 10:14:10 +0100 (Mon, 19 Feb 2007) | 1 line Provide an example of defaultdict with non-zero constant factory function. ........ r53825 | lars.gustaebel | 2007-02-19 10:54:47 +0100 (Mon, 19 Feb 2007) | 2 lines Moved misplaced news item. ........ r53826 | martin.v.loewis | 2007-02-19 11:55:19 +0100 (Mon, 19 Feb 2007) | 3 lines Patch #1490190: posixmodule now includes os.chflags() and os.lchflags() functions on platforms where the underlying system calls are available. ........ r53827 | raymond.hettinger | 2007-02-19 19:15:04 +0100 (Mon, 19 Feb 2007) | 1 line Fixup docstrings for merge(). ........ r53829 | raymond.hettinger | 2007-02-19 21:44:04 +0100 (Mon, 19 Feb 2007) | 1 line Fixup set/dict interoperability. ........ r53837 | raymond.hettinger | 2007-02-21 06:20:38 +0100 (Wed, 21 Feb 2007) | 1 line Add itertools.izip_longest(). ........ r53838 | raymond.hettinger | 2007-02-21 18:22:05 +0100 (Wed, 21 Feb 2007) | 1 line Remove filler struct item and fix leak. ........
