Not only check if src_dir exists, but look also for Lib/os.py landmark.

Issue: test_tools: test_freeze_simple_script() fails on s390x SLES 3.x: [Errno 2] No such file or directory: (...) #109615

Not only check if src_dir exists, but look also for Lib/os.py landmark.

Note: switching to 'cc54bcf17b5b5f7681f52baf3acef75b995fa1fd'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at cc54bcf17b gh-109615: Fix support test_copy_python_src_ignore() on WASM (#109970)

…#110340) * gh-109615: Fix support test_copy_python_src_ignore() (#109958) Fix the test when run on an installed Python: use "abs_srcdir" of sysconfig, and skip the test if the Python source code cannot be found. * Tools/patchcheck/patchcheck.py, Tools/freeze/test/freeze.py and Lib/test/libregrtest/utils.py now first try to get "abs_srcdir" from sysconfig, before getting "srcdir" from sysconfig. * test.pythoninfo logs sysconfig "abs_srcdir". (cherry picked from commit b89ed9d) * gh-109615: Fix support test_copy_python_src_ignore() on WASM (#109970) Not only check if src_dir exists, but look also for Lib/os.py landmark. (cherry picked from commit cc54bcf) * gh-109615: Look for 'Modules' as landmark for test_copy_python_src_ignore (GH-110108) (cherry picked from commit 20bc5f7) * gh-109748: Fix again venv test_zippath_from_non_installed_posix() (#110149) Call also copy_python_src_ignore() on listdir() names. shutil.copytree(): replace set() with an empty tuple. An empty tuple becomes a constant in the compiler and checking if an item is in an empty tuple is cheap. (cherry picked from commit 0def8c7) --------- Co-authored-by: Steve Dower <[email protected]>
