[issue26852] add the '--enable-legacy-pyc-files' option to configure

Ned Deily added the comment: Also, has anyone tried bundling the std lib into a zlib? I know that option has been around for a long time but I don't know if it still works or is even being used. Presumably, that would be another way to save space and file system entries. --

R. David Murray added the comment: Our official position (so far, mobile is a new use case since the last time it was discussed) is that we don't go out of our way to support sourceless distribution, and in general we discourage it. That is, it is left to the packager of a sourceless program

Xavier de Gaye added the comment: > but these are rebuilt when you start the interpreter, aren't they? No. Quoting PEP 3147: Case 4: legacy pyc files and source-less imports Python will ignore all legacy pyc files when a source file exists next to it. In other words, if a foo.pyc

Thomas Petazzoni added the comment: No, if you remove PEP3147 (like the Buildroot patch does), and install only the .pyc files, you have a smaller Python installation, and nothing gets "re-generated", since what you already have are the .pyc files. The .py files are not even installed on the

Thomas Petazzoni added the comment: I can also say that in the Buildroot project, we have patches to get rid of the PEP3147 stuff. Indeed, the PEP3147 forces one to have both the .py *and* the .pyc file for a given module. If you have only the .pyc file, Python does not recognize it and it

Xavier de Gaye added the comment: Install byte-code files to their legacy locations and names to save space (default are the PEP 3147 locations and names) when configure is run with '--enable-legacy-pyc-files'. The patch does not prevent ensurepip to use PEP 3147 locations and names when it
