[issue37349] venv.EnvBuilder environmental variable hooks
Caleb Donovick added the comment: I have another idea, instead of baking in the semantics of the environmental variables, we could simply add the hooks __VENV_ACTIVATE_EXTRAS__ and __VENV_DEACTIVATE_EXTRAS__ to activate. By default they would be replaced by '', but would allow subclasses to extend the behavior of activate / deactivate arbitrarily. > One thing I would consider is the ability to configure a custom_script_path > in the same way as other parameters are now. It would be used as follows: If > not None, it should specify a directory, and the files in there would be > copied to the target venv *after* the standard scripts are copied (possibly > overwriting ones already there, such as "activate"), with the same variable > substitutions that are currently done.

[issue37349] venv.EnvBuilder environmental variable hooks
Caleb Donovick added the comment: > I didn't say environment variables weren't commonly used. I'm talking about > the specific functionality this issue is about. This is likely true, to most people venv is black magic. That doesn't mean that people wouldn't use it if the functionality existed though. In fact this the first example given by virtualenvwrapper https://virtualenvwrapper.readthedocs.io/en/latest/scripts.html#example-usage I personally don't use virtualenvwrapper because you they use a centralized list of env's which is non-starter for me. I maintain dozens of envs (one per project, sometimes one per branch). So one big list would be a nightmare. > I'm talking about the code to set, reset your custom environment variables - > where is that already existent across all shells? My point is that this code is not really different than the code to set PYTHONPATH. > I'm not saying what you want is unreasonable - it's just putting it into the > stdlib this way that I'm not sure about. Is there an architecture that would be less objectionable? > I mentioned on python-ideas and opened https://bugs.python.org/issue37354 to > actually make the Activate.ps1 file static for security purposes.

Caleb Donovick added the comment: Common python libraries that make use of environmental variables: - django - flask - jupyter - TensorFlow This is just off the top my head. While most developers are probably fine just setting the required variables at a system level that doesn't mean they should. The whole point of virtual environments is to avoid global state. Overriding setup scripts is hardly a trivial task.

[issue37349] venv.EnvBuilder environmental variable hooks
New submission from Caleb Donovick : Currently EnvBuilder allows for a number of customizations of virtual environments, however, it does not allow for any modifications of the activate script itself (unless one wants to rewrite it completely). Yet, it is fairly common requirement for python packages is to set some environmental variable e.g., DJANGO_SETTINGS_MODULE=. EnvBuilder should be able extend the set of variables which are set and restored on activate / deactivate (or more generally have activate / deactivate hooks).

[issue17421] Drop restriction that meta.__prepare__() must return a dict (subclass)
Caleb Donovick added the comment: In my mind this seems like a bug. PEP 3115 states: ''' __prepare__ returns a dictionary-like object which is used to store the class member definitions during evaluation of the class body. In other words, the class body is evaluated as a function block (just like it is now), except that the local variables dictionary is replaced by the dictionary returned from __prepare__. This dictionary object can be a regular dictionary or a custom mapping type.
