gh-146410: Add --pythoninfo option to regrtest by vstinner · Pull Request #146413 · python/cpython · GitHub

Android now runs tests with --pythoninfo to dump build information.
Add display_title() function.

Issue: Android/iOS buildbot should run python -m test.pythoninfo #146410

* Android now runs tests with --pythoninfo to dump build information. * Add display_title() function.

@freakboy3742 @mhsmith: Does it sound like a reasonable addition to the Android buildbot?

If this approach is successful on Android, I will propose a similar change for iOS which also lacks python -m test.pythoninfo output.

+1 - definitely seems like a good idea to me, and I agree adding the equivalent to iOS would also make sense (Apple/__main__.py has an analogous test entry point).

Ok I merged my PR, thanks for the review.

I will keep an eye on the Android buildbot to see how it goes: https://buildbot.python.org/#/builders/1594.

Nice! https://buildbot.python.org/#/builders/1594/builds/4361 ran with my change and it works as expected. Extract of test logs:

And I was looking for this information: sys.float_info: sys.float_info(..., iec_60559=False). So the Android platform doesn't define __STDC_IEC_559__ macro.

By the way, I can see that Android is also affected by the issue gh-145410: sys.version is truncated, it doesn't display the full Clang version: 3.15.0a7+ (heads/main-dirty:b5a27bdcf03, Mar 26 2026, 10:04:01) [Clang 18.0.4 (https://android.googlesource.com/toolchain/llvm-project d8003a456.

Looks good to me. For future reference, you can also see this in the GitHub Actions run: GHA doesn't support testing Android on aarch64, but works fine on x86_64.

I noticed that Android on aarch64 doesn't run tests, but I missed the fact that Android on x86_64 runs tests in GHA! That's great!
