searchstringparser 0.2.3 released
by Moritz Beber Sept. 29, 2015

Sept. 29, 2015

Dear all, It is my pleasure to announce the first version of the *searchstringparser* package (0.2.3) on pypi. It currently contains a PLY (Python Lex-Yacc) based implementation of a general lexer and PostgreSQL specific parser. The parser translates general search queries that users might expect to be able to enter in a search form into strings that implement the correct logic for the PostgreSQL full text search functions tsquery and to_tsquery. The package is BSD licensed and you can get a full overview of the package at https://searchstringparser.readthedocs.org/ It is hosted on github and is fully integrated with Travis, AppVeyor, and Coveralls using py.test and tox. Feedback, bug reports, parser suggestions, and forks of the project are welcome! Best, Moritz Beber moritz.beber(a)gmail.com <p><a href="https://github.com/AGHerwig/searchstringparser ">searchstringparser 0.2.3</a> - Parse a more general search syntax to conform with a particular SQL dialect. (29-Sep-15)</p>

pytest-2.8.1: fixes and more fixes
by holger krekel Sept. 29, 2015

Sept. 29, 2015

Just 11 days after 2.8 hit PyPI we published pytest-2.8.1 which fixes a host of regressions and bugs, see the changelog excerpt below. Docs are also freshly generated at http://pytest.org including a streamlined PDF. Note that the pytest team now follows more SEMVER style versioning which currently means that you can expect bugfixes with 2.8.X and new features with 2.9.0 and planned incompatibilities with 3.0. Many thanks to the PR contributors and mergers of 2.8.1: Bruno Oliveira Ronny Pfannschmidt Florian Bruhin Floris Bruynooghe Eric Hunsberger Tim Staley Simon Gomizelj Russel Winder Oleg Alexandrov Michael Howitz Michael Birtwell Ben Webb Andy Freeland Abhijeet Kasurde cheers, holger krekel 2.8.1 ----- - fix #1034: Add missing nodeid on pytest_logwarning call in addhook. Thanks Simon Gomizelj for the PR. - 'deprecated_call' is now only satisfied with a DeprecationWarning or PendingDeprecationWarning. Before 2.8.0, it accepted any warning, and 2.8.0 made it accept only DeprecationWarning (but not PendingDeprecationWarning). Thanks Alex Gaynor for the issue and Eric Hunsberger for the PR. - fix issue #1073: avoid calling __getattr__ on potential plugin objects. This fixes an incompatibility with pytest-django. Thanks Andreas Pelme, Bruno Oliveira and Ronny Pfannschmidt for contributing and Holger Krekel for the fix. - Fix issue #704: handle versionconflict during plugin loading more gracefully. Thanks Bruno Oliveira for the PR. - Fix issue #1064: ""--junitxml" regression when used with the "pytest-xdist" plugin, with test reports being assigned to the wrong tests. Thanks Daniel Grunwald for the report and Bruno Oliveira for the PR. - (experimental) adapt more SEMVER style versioning and change meaning of master branch in git repo: "master" branch now keeps the bugfixes, changes aimed for micro releases. "features" branch will only be be released with minor or major pytest releases. - Fix issue #766 by removing documentation references to distutils. Thanks Russel Winder. - Fix issue #1030: now byte-strings are escaped to produce item node ids to make them always serializable. Thanks Andy Freeland for the report and Bruno Oliveira for the PR. - Python 2: if unicode parametrized values are convertible to ascii, their ascii representation is used for the node id. - Fix issue #411: Add __eq__ method to assertion comparison example. Thanks Ben Webb. - fix issue 877: properly handle assertion explanations with non-ascii repr Thanks Mathieu Agopian for the report and Ronny Pfannschmidt for the PR. - fix issue 1029: transform errors when writing cache values into pytest-warnings

[ANN] winpysetup 1.2
by Anthon van der Neut Sept. 27, 2015

Sept. 27, 2015

I am happy to announce the availability of a new version of winpysetup changes in this version: - added 3.5 and VisualStudio 2015 Community edition. Both are for post XP windows versions only. Be forewarned that VisualStudio can take a long time downloading updates it needs on a clean Windows 7, all the more reason to use winpysetup. version 1.2 dd 2015-09-27 Winpysetup ( https://bitbucket.org/ruamel/winpysetup/ ) allows setting up a clean testing environment on Windows for multiple python versions without downloading and installing MSI installers, prerequisites, yourself, all the time waiting for the last to finish in order to click a few options to start the next install. Winpysetup makes it trivial to install both 64- and 32-bit versions of the same Python version. Because tox-globinterpreter is installed as well, all these versions can be found and used on one machine. - install Windows (or clone your clean Windows Virtual Machine) - Download winpysetup.exe and start it. ( https://bitbucket.org/ruamel/winpysetup/downloads/winpysetup.exe ) - Once the program is done (now is a good time to make another snapshot if you run Windows in a VM), open a new Command Prompt (to get the change in PATH) and change to a directory without spaces in the path (e.g. C:\src). - Run: hg clone --insecure https://hg@bitbucket.org/ruamel/minimal - Change to the directory "minimal" and run tox. - Watch how tox invokes py.test succesfully against Python 2.7/3.5/3.4/3.3/2.6 and pypy (you can of course run tox immediately on your own, more interesting, code as well). Installed items include: pip (latest version even if older version is included in the installed python version), easy_install, mercurial, tox, detox, py.test and the Visual C compiler for Python 2.7 (e.g. needed for mercurial) and the other Pythons versions. Special hooks can change the behaviour of the installer. In particular: - the list of python versions to install can be easily extended/reduced - the list of default packages to install can be extended/reduced - already downloaded packages (Python, VisualStudio) can be cached. To both cache downloads, and install 32 bit versions on a 64 bit system, create a file pre_winpysetup.py next to your winpysetup.exe file before starting the latter: ---------- import sys import os import urllib2 def _download_url(self, url, path=None, base_name=None): """download a url if it is not yet in the cache """ cache = '/full/path/to/some/peristent/cache/directory/on/a/host/network drive' print 'url', url if cache and not os.path.exists(cache): cache = None if path is None: path = self._msi_dir if base_name is None: base_name = os.path.basename(url) if cache: full_name = os.path.join(cache, base_name) else: full_name = os.path.join(path, base_name) if not os.path.exists(full_name): print 'retrieving', base_name, '...' data = urllib2.urlopen(url).read() fp = open(full_name, 'wb') fp.write(data) fp.close() return full_name def pre_versions(self): self.versions = self.versions[:-1] + [ '3.5-32', '3.4-32', '3.3-32', '2.6-32', '2.7-32', ] + [self.versions[-1]] def main(verbose, installer): print 'loading winpysetup_pre' installer._download_url = _download_url installer.pre_versions = pre_versions ---------- Winpysetup has been used to setup the 2.3 environment to create the winpysetup.exe (so it will run on a clean Windows XP install). Winpysetup is used to generate the wheel files for ruamel.ordereddict and ruamel.yaml. It has been tested on: WinXP with Service Pack 2 (32 and 64 bit) Windows 7 (32 and 64 bit) Feedback (avdn(a)europython.eu or via bitbucket) is welcome, in particular if tested on other Windows environments to which I currently don't have access.

Vulture 0.7 released
by Jendrik Seipp Sept. 26, 2015

Sept. 26, 2015

vulture - Find dead code ======================== Vulture finds unused classes, functions and variables in your code. This helps you cleanup and find errors in your programs. If you run it on both your library and test suite you can find untested code. Due to Python's dynamic nature, static code analyzers like vulture are likely to miss some dead code. Also, code that is only called implicitly may be reported as unused. Nonetheless, vulture can be a very helpful tool for achieving high code quality. Download -------- http://pypi.python.org/pypi/vulture Features -------- * fast: uses static code analysis * lightweight: only one module * tested: tests itself and has 100% test coverage * complements *pyflakes* and has the same output syntax * supports Python 2.6, 2.7 and 3.x Changes ------- * Exit with exitcode 1 if path on commandline can't be found. * Test vulture with vulture. * Add tests that run vulture as a script. * Add "python setup.py test" command for running tests. * Add support for tox. * Raise test coverage to 100%. * Remove ez_setup.py. Cheers, Jendrik

ANN: A new version (0.3.8) of python-gnupg has been released.
by Vinay Sajip Sept. 26, 2015

Sept. 26, 2015

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is an enhancement and bug-fix release, and all users are encouraged to upgrade. See the project website [1] for more information. Brief summary: * Fixed #22: handled PROGRESS messages during verification and signing. * Fixed #26: handled PINENTRY_LAUNCHED messages during verification, decryption and key generation. * Fixed #28: Allowed a default Name-Email to be computed even when neither of LOGNAME and USERNAME are in the environment. * Fixed #29: Included test files missing from the tarball in previous versions. * Fixed #39: On Python 3.x, passing a text instead of a binary stream caused file decryption to hang due to a UnicodeDecodeError. This has now been correctly handled: The decryption fails with a "no data" status. * Fixed #41: Handled Unicode filenames correctly by encoding them on 2.x using the file system encoding. * Fixed #43: handled PINENTRY_LAUNCHED messages during key export. Thanks to Ian Denhardt for looking into this. * Hide the console window which appears on Windows when gpg is spawned. Thanks to Kévin Bernard-Allies for the patch. * Subkey fingerprints are now captured. * The returned value from the list_keys method now has a new attribute, key_map, which is a dictionary mapping key and subkey fingerprints to the corresponding key's dictionary. With this change, you don't need to iterate over the (potentially large) returned list to search for a key with a given fingerprint - the key_map dict will take you straight to the key info, whether the fingerprint you have is for a key or a subkey. Thanks to Nick Daly for the initial suggestion. This release [2] has been signed with my code signing key: Vinay Sajip (CODE SIGNING KEY) <vina...(a)yahoo.co.uk> Fingerprint: CA74 9061 914E AC13 8E66 EADB 9147 B477 339A 9B86 However, due to some error the signature for the source distribution (.tar.gz) didn't get uploaded. To rectify this, I have pasted it into the PyPI page for the release [2]. What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew 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 the mailing list/discussion group [4]). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

mergeall 2.2, with os.scandir() speed optimization
by Mark Lutz Sept. 25, 2015

Sept. 25, 2015

There's a new version of the mergeall folder tree synchronization tool, which uses Python 3.5's os.scandir(), if available, to radically speed up its trees comparison phase. In testing on Windows 7 and 10, the new call speeds mergeall comparisons by a factor of 5 to 10, depending on devices. This is due entirely to the elimination of system calls that os.scandir() affords. The savings is especially significant for large archives. For a 78G target use case of 50k files in 3k folders, comparison runtime fell from 40 to 7 seconds on a fast USB stick (6x); from 112 to 16 seconds on a slower stick (7x); and from 600 to 60 seconds on an ancient single-core machine (10x). Also note that the scandir() call is standard in the os module in 3.5, but can also be had for older Python releases, including 2.7 and older 3.X, via a PyPI package. mergeall uses either form if present, and falls back on the original os.listdir() scheme as a last resort to continue supporting older Pythons (though a scandir() is now strongly recommended, for obvious reasons!). All of which seems proof that language improvement and backward compatibility are not necessarily mutually exclusive. The details: 2.2 changes: http://learning-python.com/mergeall/docs/Usage-Overview.html#optimizations Main README: http://learning-python.com/mergeall/Readme.html Usage guide: http://learning-python.com/mergeall/docs/Usage-Overview.html GUI screenshot: http://learning-python.com/mergeall/examples/Screenshots/main-quit-help.png Download the package: http://learning-python.com/downloads/mergeall.zip Cheers, --M.
