New submission from STINNER Victor: While discussing how to dump the readline version in regrtest or test_readline in bpo-29854, I proposed to add a new buildbot step to dump any kinds of debug information. It would avoid to pollute test output with useless information. For example, while the hash implementation is useful for unit tests on the hash function, I dislike always dumping it in the regrtest header.
The idea would be to get a phpinfo-like report: http://php.net/phpinfo We can start with an hardcoded list using "try: import xxx except ImportError: pass else: ...", but later we may it more "pluggable" somehow? Maybe define a protocol (function with a specific name, maybe a private function?) for each module, add a command which can dump info on a single module, or all modules. Maybe start with an hardcoded list of modules, but later discover automatically all stdlib modules? I don't expect a regular list of information, but more like a long key-value list. Attached pythoninfo.py is an example of such script. It works on Python 2.7-3.7. Example of Python 3.7 output on my Linux PC: --- cpu_count: 4 cwd: /home/haypo/prog/GIT/misc/python filesystem_encoding: utf-8 filesystem_errors: surrogateescape gdb_version: GNU gdb (GDB) Fedora 7.12.1-48.fc25 hash algorithm: ('siphash24', '64bit') locale_encoding: UTF-8 platform: Linux-4.11.6-201.fc25.x86_64-x86_64-with-fedora-25-Twenty_Five python_implementation: CPython readline_library_version: 6.3 readline_runtime_version: 0x603 readline_version: 0x603 sys.byteorder: little sys.flags: sys.flags(debug=0, inspect=0, interactive=0, optimize=0, dont_write_bytecode=0, no_user_site=0, no_site=0, ignore_environment=0, verbose=0, bytes_warning=0, quiet=0, hash_randomization=1, isolated=0) sys.maxsize: 9223372036854775807 sys.version: 3.7.0a0 (heads/testcapi_stack_pointer_master:81dd3fb, Jul 6 2017, 13:10:36) [GCC 6.3.1 20161221 (Red Hat 6.3.1-1)] tcl_version: 8.6 --- Later, we may add a JSON output format, to allow to collect informations of all buildbots. For example, check all tested readline versions. ---------- components: Tests files: pythoninfo.py messages: 297885 nosy: haypo priority: normal severity: normal status: open title: Add a "python info" command somewhere to dump versions of all dependencies type: enhancement versions: Python 3.7 Added file: http://bugs.python.org/file46994/pythoninfo.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30871> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
