It seems like the same (or similar? I didn't check) tests fail on Debian:

I also ran the Python test suite on Debian sid using the master branch of Python and all tests pass:

I also ran the full test suite on Debian Stretch: again, all tests passed.

Maybe the package builder use a custom configuration or patches? Or issues are specific to Python 3.7? (again, I tested the master branch)

Hmm, what about version of gcc? I suspect some troubles could be caused by gcc version 8 (we have in openSUSE), or LTO option switched on?

> Hmm, what about version of gcc? I suspect some troubles could be caused by gcc version 8 (we have in openSUSE), or LTO option switched on?

For my tests on Fedora, I used gcc 8.1.1. I used the OpenSUSE configure command which includes --with-lto.

I built and ran these tests using commands from msg320892 on openSUSE Leap 42.3, and all tests are passed.

It's somehow complicated, in the build chroot I can make tests run only with LD_LIBRARY_PATH set to $(readlink -f Python-3.7.0) and PYTHONPATH to Lib directory. However, then the set of failed tests changes. For example test_runpy runs without problems, but other fails:

5 tests failed:
    test_asyncio test_concurrent_futures test_gdb test_logging
    test_multiprocessing_main_handling

(complete log is attached)

Yes, it must be something in the chroot, because when run in the plain command line, all tests as well on openSUSE Tumbleweed (with the latest updates).

393 tests OK.

Are you testing with patches? It may be interesting to try to get these patches upstream:

[   59s] Patch #1 (Python-3.0b1-record-rpm.patch):
[   59s] Patch #2 (python-3.6.0-multilib-new.patch):

Some patches seem old. Are they still needed? Where can I find these patches? I'm interested by patches modifying site.py for example.

> Are you testing with patches? It may be interesting to try to get these patches upstream:

Tested both and without patches, the same results. Everything in openSUSE is done in open (rather strikingly similar to RH openness, although things are even more simple, because so much is web accessible), so the official project for development of openSUSE python3 is https://build.opensuse.org/package/show/devel:languages:python:Factory/python3 all patches are there (from there I can make push request to the https://build.opensuse.org/package/show/openSUSE:Factory/python3 which is where openSUSE packages come from).

> Are you testing with patches? It may be interesting to try to get these patches upstream: (...)

I applied manually these patches on 3.7: the 6 tests still pass.

> Some patches seem old. Are they still needed? Where can I find these patches? I'm interested by patches modifying site.py for example.

I created PR 8057 to upstream distutils-reproducible-compile.patch.

Matej Cepl: Would you mind to try to find the original author of this patch file? I would like to credit them.

    self.assertEqual(flags, 0b1)
AssertionError: 3 != 1


This failure looks suspicious. I looked at the code, and the tested function behaves differently depending of the SOURCE_DATE_EPOCH environment variable is set.

Aha! I found something:

$ SOURCE_DATE_EPOCH=1530605018 ./python -m test -j0
...
6 tests failed:
    test_cmd_line_script test_compileall test_importlib
    test_multiprocessing_main_handling test_py_compile test_runpy
...

See bpo-29708 and PEP 552 for more info about reproducible builds.

(by Nick Coghlan):

In particular, if a build system sets SOURCE_DATE_EPOCH without
specifying a pyc format for py_compile or compileall, Python 3.7 will
give you checked hashes by default:
https://docs.python.org/3/library/py_compile.html?highlight=source_date_epoch#py_compile.compile

we're compiling similar to debian and getting the same issues now only with 3.7 so interested in what the resolution is.  I tried both w/ and w/o setting SOURCE_DATE_EPOCH and still get failures.

Actually, py_compile will _force_ the CHECKED_HASH mode if SOURCE_DATE_EPOCH is set, regardless of what you specified for py_compile or compileall.  I'm not sure if that's actually intended or a bug.

The fix for the tests is to actually be aware of py_compile behavior and control for SOURCE_DATE_EPOCH.  I submitted a PR with a fix.

I dislike that having SOURCE_DATE_EPOCH set magically changes command line tools behavior. In my view, this problem should be fixed by reverting ccbe5818af2.

Perhaps SOURCE_DATE_EPOCH should only be consulted to determine the default behavior if invalidation_mode was not passed explicitly to py_compile.compile().

https://github.com/python/cpython/pull/9607 turns SOURCE_DATE_EPOCH into a *default* rather than absolute override.

test_cmd_line_script and test_runpy fail due to the lack of support for hash-based .pycs in zipimport, which needs fixing also.

Once we decided to merge or reject this PR, we should maybe update the PEP 552 to clarify the interaction with the SOURCE_DATE_EPOCH environment variable.

There are still tests which fail when SOURCE_DATE_EPOCH env var is defined:

$ SOURCE_DATE_EPOCH=0 ./python -m test -j0 -r
(...)
3 tests failed:
    test_cmd_line_script test_multiprocessing_main_handling test_runpy
(...)

https://github.com/python/cpython/pull/10327 fixes the remaining test failures.

As https://github.com/python/cpython/pull/10327 has been merged, I think this issue can be closed?

The Versions field of this issue is set to Python 3.7, but 7 tests are failing with:

$ SOURCE_DATE_EPOCH=0 ./python -m test -j0 -r -u all,-gui
(...)
7 tests failed:
    test_cmd_line_script test_compileall test_importlib
    test_multiprocessing_main_handling test_posix test_py_compile
    test_runpy

Note: the full test suite pass with SOURCE_DATE_EPOCH=0 on master.

Looks like in https://github.com/python/cpython/pull/10327, Serhiy Storchaka considers fixing these issues for 3.8 only - "It is easier to skip the test on 3.7." and then remove the "needs backport to 3.7" label. How about changing the target version to 3.8 only and close this issue?

"What’s New In Python 3.7" mentions twice "build reproducibility":
https://docs.python.org/dev/whatsnew/3.7.html

Got it. Thanks for the pointer.

test_compileall, test_importlib, test_py_compile: I created https://github.com/python/cpython/pull/10775 backport.

test_cmd_line_script, test_runpy and test_multiprocessing_main_handling failures are related to zipimport. They have been fixed in master by commit a6e956bcb0edbfe7f18af9be2215a5326ea6bf05 which modifies Lib/zipimport.py... but in 3.7, zipimport is written in C. It seems non-trivial to fix zipimport, and I'm not sure that it's worth it.

Note: test_posix now pass, no idea why it failed a few days ago.

With this change, only 3 tests fail on 3.7, and all these 3 fail because of zipimport: test_cmd_line_script, test_multiprocessing_main_handling and test_runpy.

Now I agree to close the issue :-)

I'm ok to not fix zipimport in 3.7.

Anyway, it's not like Python is perfect in the master branch: frozenset in marshal is still not reproducible. See bpo-29708.

These tests were fixed by:

    bpo-34726: Fix handling of hash-based pycs in zipimport. (GH-10327)
    
    Current support for hash-based bytecode files in `zipimport` is rather
    sparse, which leads to test failures when the test suite is ran with
    the ``SOURCE_DATE_EPOCH`` environment variable set.
    
    This teaches zipimport to handle hash-based pycs properly.
