[baseline 0.2.1] Easy String Baseline
by Dan Gass March 30, 2020

March 30, 2020

I am please to announce the availability of the "baseline" package. This tool streamlines creation and maintenance of tests which compare string output against a baseline. It offers a mechanism to compare a string against a baselined copy and update the baselined copy to match the new value when a mismatch occurs. The update process includes a manual step to facilitate a review of the change before acceptance. The tool uses multi-line string format for string baselines to improve readability … [View More]for human review. Docs: https://baseline.readthedocs.io/en/latest/ PyPi: https://pypi.org/project/baseline/ Repo: https://github.com/dmgass/baseline License: MIT With Regards, Dan Gass (dan.gass at gmail) *********** Quick Start *********** Create an empty baseline with a triple quoted multi-line string. Place the ending triple quote on a separate line and indent it to the level you wish the string baseline update to be indented to. Add a compare of the string being tested to the baseline string. Then save the file as ``fox.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected Run ``fox.py`` and observe that the ``assert`` raises an exception since the strings are not equal. Because the comparison failed, the tool located the triple quoted baseline string in the source file and updated it with the miscompared value. When the interpretter exited, the tool saved the updated source file but changed the file name to ``fox.update.py``: .. code-block:: python from baseline import Baseline expected = Baseline(""" THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG. """) test_string = "THE QUICK BROWN FOX\n JUMPS\nOVER THE LAZY DOG." assert test_string == expected After reviewing the change with your favorite file differencing tool, accept the change by either manually overwriting the original file or use the ``baseline`` command line tool to scan the directory for updated scripts and accept them: .. code-block:: shell $ python -m baseline * Found updates for: fox.py Hit [ENTER] to update, [Ctrl-C] to cancel fox.update.py -> fox.py Run ``fox.py`` again and observe the ``assert`` does not raise an exception nor is a source file update generated. If in the future the test value changes, the ``assert`` will raise an exception and cause a new source file update to be generated. Simply repeat the review and acceptance step and you are back in business! <P><A HREF="https://baseline.readthedocs.io/en/latest/"> baseline 0.2.1</A> - Easy String Baseline (07-Jun-18) [View Less]

EPS: Announcing the Guido van Rossum Core Developer Grant
by M.-A. Lemburg Jan. 31, 2019

Jan. 31, 2019

At the last General Assembly of the EuroPython Society (EPS) at EuroPython 2018 in Edinburgh, we voted on a new grant program we want to put in place for future EuroPython conferences. We all love Python and this is one of the main reasons we are putting on EuroPython year after year, serving the "cast of thousands" which support Python. But we also believe it is important to give something back to the main team of developers who have contributed lots of their time and energy to make Python … [View More]

ANN: A new version (0.4.4) of python-gnupg has been released. It contains a security-related change - please update to this version
by Vinay Sajip Jan. 24, 2019

Jan. 24, 2019

A new version of the Python module which wraps GnuPG has been released. What Changed?=============This is an enhancement and security-fix release, and all users are stronglyencouraged to upgrade. Brief summary: * Fixed #108: Changed how any return value from the on_data callable is processed. In earlier versions, the return value was ignored. In this version, if the return value is False, the data received from gpg is not buffered. Otherwise (if the value is None or True, for … [View More]example), the data is buffered as normal. This functionality can be used to do your own buffering, or to prevent buffering altogether. The on_data callable is also called once with an empty byte-string to signal the end of data from gpg. * Fixed #97: Added an additional attribute check_fingerprint_collisions to GPG instances, which defaults to False. It seems that gpg is happy to have duplicate keys and fingerprints in a keyring, so we can't be too strict. A user can set this attribute of an instance to True to trigger a check for collisions. * Fixed #111: With GnuPG 2.2.7 or later, provide the fingerprint of a signing key for a failed signature verification, if available. * Fixed #21: For verification where multiple signatures are involved, a mapping of signature_ids to fingerprint, keyid, username, creation date, creation timestamp and expiry timestamp is provided. * Added a check to disallow certain control characters ('\r', '\n', NUL) in passphrases. This fix mitigates against CVE-2019-6690. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vinay_sajip at yahoo.co.uk>Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 Recent changes to PyPI don't show the GPG signature with the download links.An alternative download source where the signatures are available is the project'sown downloads page [5]. What Does It Do?================The gnupg module allows Python programs to make use of thefunctionality provided by the Gnu Privacy Guard (abbreviated GPG orGnuPG). Using this module, Python programs can encrypt and decryptdata, digitally sign documents and verify digital signatures, manage(generate, list and delete) encryption keys, using proven Public KeyInfrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as itmakes use of the subprocess module which appeared in that version ofPython. This module is a newer version derived from earlier work byAndrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg>>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory')>>> gpg.list_keys() [{...'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2','keyid': '197D5DAC68F1AAB2','length': '1024','type': 'pub','uids': ['', 'Gary Gross (A test user) <gary.gr... at gamma.com>']},{...'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A','keyid': '0C5FEFA7A921FC4A','length': '1024',...'uids': ['', 'Danny Davis (A test user) <danny.da... at delta.com>']}]>>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A'])>>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n\nhQIOA/6NHMDTXUwcEAf.-----END PGP MESSAGE-----\n'>>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret')>>> str(decrypted) 'Hello, world!'>>> signed = gpg.sign("Goodbye, world!", passphrase='secret')>>> verified = gpg.verify(str(signed))>>> print "Verified" if verified else "Not verified" 'Verified' As always, your feedback is most welcome (especially bug reports [3],patches and suggestions for improvement, or any other points via themailing list/discussion group [4]).

ANN: gcc-python-plugin 0.17
by David Malcolm Jan. 23, 2019

Jan. 23, 2019

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the CPython interpreter within GCC, allowing you to write new compiler warnings in Python, generate code visualizations, etc. This release adds support for gcc 9 (along with continued support for gcc 4.6, 4.7, 4.8, 4.9, 5, 6, 7, and 8). Unfortunately, the reference-count checker no longer works for gcc 7 onwards, so it is disabled when embedded in those builds of gcc.
