first post introduction and question regarding lto

by Soldea, Octavian

Hello This is my first post after I just have subscribed to the Python-Dev mailing list. In this context, the welcome confirmation message suggested to introduce myself. My name is Octavian Soldea and I am with the Python optimization team in DSLOT group in Intel, Santa Clara, California. In the past I have received a PhD in Computer Science from the Technion, Israel Institute of Technology in Computer Vision. I would like to ask regarding the possibility of compiling Python with lto only. My question is if is the community interested to enable the possibility of compiling Python with lto only, i.e. without pgo? I have followed https://bugs.python.org/issue29243 and https://bugs.python.org/issue29641 however, it is not clear if the separate compilation is already implemented. In my opinion this is a good option since pgo is not always desired. Best regards, Octavian

Interrupt thread.join() with Ctrl-C / KeyboardInterrupt on Windows

by Jonathan Slenders

Hi all, Is it possible that thread.join() cannot be interrupted on Windows, while it can be on Linux? Would this be a bug, or is it by design? import threading, time def wait(): time.sleep(1000) t = threading.Thread(target=wait) t.start() t.join() # Press Control-C now. It stops on Linux, while it hangs on Windows. Tested on Python 3.6. Thanks, Jonathan

[RELEASED] Python 3.4.7 is now available

by Larry Hastings

On behalf of the Python development community and the Python 3.4 release team, I'm pleased to announce the availability of Python 3.4.7. Python 3.4 is now in "security fixes only" mode. This is the final stage of support for Python 3.4. Python 3.4 now only receives security fixes, not bug fixes, and Python 3.4 releases are source code only--no more official binary installers will be produced. You can find Python 3.4.7 here: https://www.python.org/downloads/release/python-347/ Happy Pythoning, //arry/

[ANN] Daily Windows builds of Python 3.x

by Steve Dower

Hi all As part of a deal with Zach Ware at PyCon, I agreed that if he removed the Subversion dependency from our builds, I would set up daily Windows builds of Python. Zach did an excellent job, and so I am now following through on my half of the deal :) For a while I've been uploading the official releases to nuget.org. These packages can be installed with nuget.exe (latest version always available at https://aka.ms/nugetclidl), which is quickly becoming a standard tool in Microsoft's build toolsets. It's very much a CI-focused package manager, rather than a user-focused one, and CI on Windows was previously an area where it was difficult to use Python. See the official feed at https://www.nuget.org/packages/python, and related packages pythonx86, python2 and python2x86. For people looking for an official "no installer" version of Python for Windows, this is it. And since all the infrastructure was there already, I decided to publish daily builds in a similar way to myget.org: https://www.myget.org/feed/python/package/nuget/pythondaily To install the latest daily build, run nuget.exe with this command: nuget.exe pythondaily -Source https://www.myget.org/F/python/api/v3/index.json (Note that if you already have a "pythondaily" package in that directory, nuget will consider the requirement satisfied. As I said, it's meant for reproducible CI builds rather than users who want to update things in the least amount of keystrokes :) ) The sys.version string contains the short commit hash. Please include this string when reporting bugs in these builds. Also, only the amd64 Release build is available pre-built. >>> sys.version '3.7.0a0 (remotes/origin/master:733d0f63c, Aug 8 2017, 15:56:14) [MSC v.1900 64 bit (AMD64)]' Hopefully this is valuable for people who want to include daily builds in their own test runs or validate recent bug fixes. Cheers, Steve

[RELEASED] Python 3.5.4 is now available

by Larry Hastings

On behalf of the Python development community and the Python 3.5 release team, I'm pleased to announce the availability of Python 3.5.4. Python 3.5.4 is the final 3.5 release in "bug fix" mode. The Python 3.5 branch has now transitioned into "security fixes mode"; all future improvements in the 3.5 branch will be security fixes only, and no conventional bug fixes will be merged. You can find Python 3.5.4 here: https://www.python.org/downloads/release/python-354/ Python 3.4.7 final will be released later today. Happy Pythoning, //arry/

PyThreadState_GET() returns NULL from within PyImport_GetModuleDict()

by Patrick Rutkowski

I'm working on Windows. I have the following dead simple embedding code that I'm using to test out the python interpreter: ============================================================ Py_SetProgramName(L"MyApp"); Py_SetPath( L"C:\\Users\\rutski\\Documents\\python\\PCBuild\\amd64\\python36.zip;" L"C:\\Users\\rutski\\Documents\\python\\DLLs;" L"C:\\Users\\rutski\\Documents\\python\\lib;" L"C:\\Users\\rutski\\Documents\\python\\PCBuild\\amd64;" L"C:\\Users\\rutski\\Documents\\python;" L"C:\\Users\\rutski\\Documents\\python\\lib\\site-packages"); Py_Initialize(); PyRun_SimpleString( "from time import time,ctime\n" "print('Today is', ctime(time()))\n"); ============================================================ This code crashes trying to access address 0x00000010 from within PyRun_SimpleString(). The sequence of event's is this: 1) PyRun_SimpleString() tries to do AddModule("__main__") 2) AddModule tries to do PyImport_GetModuleDict() 3) PyImport_GetModuleDict() tries to doPyThreadState_GET()->interp 4) PyThreadState_GET() returns NULL, so the ->interp part crashes. The weird thing is that calling PyImport_GetModuleDict() from within my application directly works just fine. Weirder still is that the whole thing actually executes fine if I build a windows command line application with the embed code in main(), and execute it from a terminal. The crash only happens when building a Windows GUI application and calling the embed code in WinMain(). This is a python interpreter that I built from source on windows using PCbuild\build.bat, so that I could track the crash. However, the exact same crash was happening with the stock interpreter provided by the python windows installer. Does anyone have any ideas here? -Patrick

Python 3.5 has now transitioned to "security fixes only" mode

by Larry Hastings

The Python 3.5 branch has now entered "security fixes only" mode. No more bugfixes will be accepted into the 3.5 branch. In keeping with our modern workflow, I have changed the permissions on the 3.5 branch on Github so that only release managers can accept PRs into the branch. Please add me to your 3.5 security fix PRs, as I'm the one responsible for accepting them. (This was already true for the 3.4 branch, too.) I neglected to mention it in the release announcement, but this transition also means no more binary installers for 3.5 releases. This signals the end of my interactions with macOS Platform Expert Ned Deily and Windows Platform Expert Steve Dower when making releases. I just wanted to mention what a pleasure it has been working with those two gentlemen for the two Python releases I've RM'd for. They've made me look good every time. Cheers, //arry/
