[issue22213] Make pyvenv style virtual environments easier to configure when embedding Python
PyScripter added the comment: To Steve: I want the embedded venv to have the same sys.path as if you were running the venv python interpreter. So my method takes into account for instance the include-system-site-packages option in pyvenv.cfg. Also my method sets sys.prefix in the same way as the venv python interpreter. -- ___ Python tracker <https://bugs.python.org/issue22213> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22213] Make pyvenv style virtual environments easier to configure when embedding Python
PyScripter added the comment:
Just in case this will be of help to anyone, I found a way to use venvs in
embedded python.
- You first need to Initialize python that is referred as home in pyvenv.cfg.
- Then you execute the following script:
import sys
sys.executable = r"Path to the python executable inside the venv"
path = sys.path
for i in range(len(path)-1, -1, -1):
if path[i].find("site-packages") > 0:
path.pop(i)
import site
site.main()
del sys, path, i, site

[issue38398] PyUnicode functions are not exported by python 2 in Ubuntu
New submission from PyScripter : As per title PyUnicode functions, such as PyUnicode_FromWideChar, are not exported on Ubuntu and possibly other Linux systems. This is a show stopper for embedded Python. To confirm: >>> import ctypes >>> hasattr(ctypes.pythonapi, "PyUnicode_FromWideChar") It should return True, but it returns False. I have tested with the default Ubuntu python 2.7.15 and with compiled python 2.7.16. Note that the problem does not exist in python3 and also python 2.7 and 3.x in Windows. So it is only python 2.7 in Ubuntu. -- components: Library (Lib) messages: 354105 nosy: pyscripter priority: normal severity: normal status: open title: PyUnicode functions are not exported by python 2 in Ubuntu type: crash versions: Python 2.7 ___ Python tracker <https://bugs.python.org/issue38398> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue35706] Make it easier to use a venv with an embedded Python interpreter
PyScripter added the comment: "Personally, I am 100% against letting an embedded runtime automatically pick up any settings from the environment. You don't know where they came from." Why is that? When the embedding application is using Py_SetPythonHome there is clear intent to use a specific python setup. This is no different to using any other Python setup. Why venvs should be treated differently that standard installations? As to manually setting the path, why pass the burden to the embedding application. The idea is that python, in the embedding application, should work as in the python executable. Trying to match the complex and evolving algorithms that python uses to setup the path, is a huge and unnecessary burden on the embedding application. -- ___ Python tracker <https://bugs.python.org/issue35706> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue2199] cPickle error with gtk GEnum classes
New submission from PyScripter: cPickle has problems loading instances of gtk gobject.GEnum classes. gobject.GEnum is a subclass of int. On the other hand pickle handles those classes correctly. Since cPickle is meant to be a faster version of pickle this needs to be consider a bug. To test run the following script: import gtk ##import pickle import cPickle as pickle simple_types = ( bool, int, long, float, complex, basestring, type(None), ) d = vars(gtk) for (i,j) in d.iteritems(): if isinstance(j, simple_types): try: s = pickle.dumps(j, pickle.HIGHEST_PROTOCOL) obj = pickle.loads(s) except (ValueError, TypeError): print j, type(j) If you replace cPickle with pickle then the script runs fine. -- components: Library (Lib) messages: 63091 nosy: pyscripter severity: normal status: open title: cPickle error with gtk GEnum classes versions: Python 2.5 __ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue2199> __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

To reproduce the error:
a) Save the following file in utf-8 format as c:\temp\module1.py

[issue1685] linecache .updatecache fails on utf8 encoded files
New submission from PyScripter: linecache.updatecache works as follows after it finds a module name: fp = open(fullname, 'rU') lines = fp.readlines() fp.close() It then tries to detect a file encoding comment... The problem is that readlines fails with a UnicodeDecodeError if the file is utf8 encoded, the preferred locale encoding is something else and the file contains characters that cannot be decoded. Instead the function should: a) read the raw data into a bytes object b)then search for a file encoding comment and c)use one if found else use utf8 since this is not the default file encoding. -- components: Library (Lib) messages: 58958 nosy: pyscripter severity: normal status: open title: linecache .updatecache fails on utf8 encoded files versions: Python 3.0 __ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1685> __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
