[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 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)

ANN: Datatest 0.9.4 Released
by Shawn Brown June 3, 2019

June 3, 2019

Datatest provides tools for test driven data-wrangling and data validation. It supports both pytest and unittest style testing. I've been working to get datatest ready for a few pre-PyCon updates. This latest release takes many of the "how-to" solutions and brings them into the core package. * Docs - https://datatest.readthedocs.io/ * PyPI - https://pypi.org/project/datatest/ * Devel - https://github.com/shawnbrown/datatest Upgrade an existing installation to 0.9.4: pip install --upgrade datatest What's New in Datatest 0.9.4: * Added Python 3.8 testing and support. * Added new validate methods (moved from how-to recipes into core module): * Added approx() method to require for approximate numeric equality. * Added fuzzy() method to require strings by approximate match. * Added interval() method to require elements within a given interval. * Added set(), subset(), and superset() methods for explicit membership checking. * Added unique() method to require unique elements. * Added order() method to require elements by relative order. * Changed default sequence validation to check elements by index position rather than checking by relative order. * Added fuzzy-matching allowance to allow strings by approximate match. * Added Predicate class to formalize behavior--also provides inverse-matching with the inversion operator (~). * Added new methods to Query class: * Added unwrap() to remove single-element containers and return their unwrapped contents. * Added starmap() to unpack grouped arguments when applying a function to elements. * Fixed improper use of assert statements with appropriate conditional checks and error behavior. * Added requirement class hierarchy (using BaseRequirement). This gives users a cleaner way to implement custom validation behavior and makes the underlying codebase easier to maintain. * Changed name of ProxyGroup to RepeatingContainer. * Changed "How To" examples to use the new validation methods.

PyCA cryptography 2.7 released
by Paul Kehrer May 31, 2019

May 31, 2019

PyCA cryptography 2.7 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X509, key derivation functions, and much more. We support Python 2.7, Python 3.4+, and PyPy. Changelog (https://cryptography.io/en/latest/changelog/#v2-7): * Updated Windows, macOS, and manylinux1 wheels to be compiled with OpenSSL 1.1.1c. * BACKWARDS INCOMPATIBLE: We no longer distribute 32-bit manylinux1 wheels. Continuing to produce them was a maintenance burden. * BACKWARDS INCOMPATIBLE: Removed the cryptography.hazmat.primitives.mac.MACContext interface. The CMAC and HMAC APIs have not changed, but they are no longer registered as MACContext instances. * Removed support for running our tests with setup.py test. Users interested in running our tests can continue to follow the directions in our development documentation. * Add support for Poly1305 when using OpenSSL 1.1.1 or newer. * Support serialization with Encoding.OpenSSH and PublicFormat.OpenSSH in Ed25519PublicKey.public_bytes . * Correctly allow passing a SubjectKeyIdentifier to from_issuer_subject_key_identifier() and deprecate passing an Extension object. The documentation always required SubjectKeyIdentifier but the implementation previously required an Extension. -Paul Kehrer (reaperhulk)

NumPy 1.16.4 released.
by Charles R Harris May 28, 2019

May 28, 2019

Charles R Harris <charlesr.harris(a)gmail.com> Apr 21, 2019, 8:39 PM to numpy-discussion, SciPy, SciPy-User, bcc: python-announce-list Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.16.4 which contains several fixes for newly reported bugs. The Python versions supported in this release are 2.7 and 3.5-3.7. Downstream developers building this release should use Cython >= 0.29.2 and, if using OpenBLAS, OpenBLAS > v0.3.7. Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.16.4/>, source archives and release notes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.16.4>. If you are installing using pip, you may encounter a problem with older installed versions of NumPy that pip did not delete becoming mixed with the current version, resulting in an ``ImportError``. That problem is particularly common on Debian derived distributions due to a modified pip. The fix is to make sure all previous NumPy versions installed by pip have been removed. See #12736 <https://github.com/numpy/numpy/issues/12736> for discussion of the issue. *Contributors* A total of 10 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Charles Harris - Eric Wieser - Dennis Zollo + - Hunter Damron + - Jingbei Li + - Kevin Sheppard - Matti Picus - Nicola Soranzo + - Sebastian Berg - Tyler Reddy *Pull requests merged* A total of 16 pull requests were merged for this release. - gh-13392: BUG: Some PyPy versions lack PyStructSequence_InitType2. - gh-13394: MAINT, DEP: Fix deprecated ``assertEquals()`` - gh-13396: BUG: Fix structured_to_unstructured on single-field types (backport) - gh-13549: BLD: Make CI pass again with pytest 4.5 - gh-13552: TST: Register markers in conftest.py. - gh-13559: BUG: Removes ValueError for empty kwargs in arraymultiter_new - gh-13560: BUG: Add TypeError to accepted exceptions in crackfortran. - gh-13561: BUG: Handle subarrays in descr_to_dtype - gh-13562: BUG: Protect generators from log(0.0) - gh-13563: BUG: Always return views from structured_to_unstructured when... - gh-13564: BUG: Catch stderr when checking compiler version - gh-13565: BUG: longdouble(int) does not work - gh-13587: BUG: distutils/system_info.py fix missing subprocess import (#13523) - gh-13620: BUG,DEP: Fix writeable flag setting for arrays without base - gh-13641: MAINT: Prepare for the 1.16.4 release. - gh-13644: BUG: special case object arrays when printing rel-, abs-error Cheers, Charles Harris
