Upgrade to pip 9.0.3 (due to TLS deprecation)
by Sumana Harihareswara May 2, 2018

May 2, 2018

Mac users: If you are running macOS/OS X version 10.12 or older, you need to upgrade to the latest pip (9.0.3) to connect to the Python Package Index securely: curl https://bootstrap.pypa.io/get-pip.py | python Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS < 10.13. Official release notes: https://pip.pypa.io/en/stable/news/ Context: As PSF blogged last year https://pyfound.blogspot.com/2017/01/time-to-upgrade-your-python-tls-v12.ht… , on June 30, 2018, Python.org sites are going to entirely stop supporting TLS versions 1.0 and 1.1, because our CDN provider is deprecating support for those versions. We are launching the new PyPI (in beta at https://pypi.org) this month and replacing the legacy PyPI (https://pypi.python.org). Here's the beta announcement for the new PyPI: https://pyfound.blogspot.com/2018/03/warehouse-all-new-pypi-is-now-in-beta.… Warehouse, the codebase for the new PyPI, does not support TLS 1.0 or 1.1. We're warning our users early with this message. Also, as of late March, the Python Package Index has started doing brownouts of the deprecated TLS versions. For some portion of each hour, anyone attempting to access PyPI with TLSv1.0 or TLSv1.1 will get a 403 response with an informative error. As we get closer to the deadline, we will be ramping up the amount of time the endpoint is down for the deprecated TLS versions. The ultimate goal is to have it be 100% unavailable on and after April 8th, prior to the final deadline (because we can give a good error message -- once June 30th hits, it will just be an uninformative OpenSSL error). More info: * https://github.com/pypa/warehouse/issues/3293 * https://github.com/pypa/warehouse/issues/3411 * https://status.python.org/incidents/btjtz01lzp88 Thank you. Please publicize this. -- Sumana Harihareswara Warehouse project manager Changeset Consulting https://changeset.nyc

ANN: PyObjC 4.2.1

Hi, I just pushed PyObjC 4.2.1 to PyPI. This is a very minor bug fix release and most people don’t have to upgrade. There’s only a single fix for some people from source: the automatic detection of the use of “—with-system-ffi” works again (it was disabled in 4.2 because that feature didn’t work with /usr/bin/python). The fix doesn’t affect users of binary wheels. Ronald

Argument is a block, but no signature available

I’m trying to use a Completion Handler block as an argument for a Cocoa AVMIDIPlayer method: midiPlayer = AVMIDIPlayer.alloc().initWithContentsOfURL_soundBankURL_error_(midiFile, None, None) midiPlayer.prepareToPlay() midiPlayer.play_(myCompletionHandler) But I get: Argument 2 is a block, but no signature available From what I can find out, this points to a bit in the metadata of PyObjC that needs a bit of work. Is that the case? I’m using the default version 2.5.1 bundled with MacOS. Thanks Ben

ANN: PyObjC 4.2

I’ve just published PyObjC 4.2 on PyPI. This is primarily a bug fix release, but also introduces bindings to the BusinessChat framework introduced in macOS 10.13.4. Those bindings are probably totally uninteresting for most users as the framework can only be used by a small subset of macOS developers. The full list of changes for this release: * Add bindings to the BusinessChat framework introduced in macOS 10.13.4 * Update metadata for Xcode 9.3 * Issue #233 Fix crash in Security.AuthorizationCopyRights() wrapper * Issue #234 Fix crash in AuthorizationExecuteWithPrivileges() wrapper Reported by Vangelis Koukis * Ensure doctest can work with modules containing subclasses of NSObject Reported by Just van Rossum * Issue #236 : Importing can sometimes fail in multi-threaded scenarios Fix by Max Bélanger * Undeprecate treating struct wrappers as sequences. Removing this feature would break too much existing code, hence deprecating is not really an option. Furthermore, this would also break some nice idioms. * Pull request #17: Fix python 3 issues in PyObjCTools.AppHelper and PyObjCTools.Conversion Fix by Max Bélanger Regards, Ronald
