[issue28467] Installer should be a 64-bit executable
John Taylor added the comment: python-3.6.0b2-embed-amd64.zip will load the interpreter as is easy to install. The Python Embedded Distribution documentation mentions needing ucrtbase.dll, which is already installed on Nano Server. One small pain point is that ctrl-z seems to exit/suspend the docker container and drop you back to the host. Under the normal, non-embedded python, you can just run exit() to quit the interpreter. Since this option is not available under the embedded version, you have to import sys; sys.exit() to quit the interpreter under Nano Server. Also, there is no pip.exe. Thank you for the information regarding MSI which I was not aware of. Upon further consideration, I believe this issue can be closed because the embedded distribution works on Nano Server. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28467> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

def info(title):
print(title)
print('module name:', __name__)
if hasattr(os, 'getppid'): # only available on Unix
print('parent process:', os.getppid())
print('process id:', os.getpid())
os.getppid() is now available on Windows, so you can remove the if statement.

[issue24904] Patch: add timeout to difflib SequenceMatcher ratio() and quick_ratio()
New submission from John Taylor: SequenceMatcher in the difflib module contain ratio() and quick_ratio() methods which can take a long time to run with certain input. One example is two slightly different versions of jquery.min.js. I have written a patch against python-350b4 that adds a timeout to these methods. The new functionality also has the capability to fall through to the next quickest comparison method should a timeout occur. If a timeout does occur and using a fall through method is not desired, then -1 is returned for the ratio. I'd like this to be incorporated into Python 3.5.0 if it is not too late. -- components: Library (Lib) files: difflib-diff.patch keywords: patch messages: 248919 nosy: jftuga priority: normal severity: normal status: open title: Patch: add timeout to difflib SequenceMatcher ratio() and quick_ratio() type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file40217/difflib-diff.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24904 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
