virtualenv cloning script.
|
|
|
|
A script for cloning a non-relocatable virtualenv.
|
|
|
|
Virtualenv provides a way to make virtualenv's relocatable which could then be
|
|
copied as we wanted. However making a virtualenv relocatable this way breaks
|
|
the no-site-packages isolation of the virtualenv as well as other aspects that
|
|
come with relative paths and '/usr/bin/env' shebangs that may be undesirable.
|
|
|
|
Also, the .pth and .egg-link rewriting doesn't seem to work as intended. This
|
|
attempts to overcome these issues and provide a way to easily clone an
|
|
existing virtualenv.
|
|
|
|
It performs the following:
|
|
|
|
- copies sys.argv[1] dir to sys.argv[2]
|
|
- updates the hardcoded VIRTUAL_ENV variable in the activate script to the
|
|
new repo location. (--relocatable doesn't touch this)
|
|
- updates the shebangs of the various scripts in bin to the new python if
|
|
they pointed to the old python. (version numbering is retained.)
|
|
|
|
it can also change '/usr/bin/env python' shebangs to be absolute too,
|
|
though this functionality is not exposed at present.
|
|
|
|
- checks sys.path of the cloned virtualenv and if any of the paths are from
|
|
the old environment it finds any .pth or .egg-link files within sys.path
|
|
located in the new environment and makes sure any absolute paths to the
|
|
old environment are updated to the new environment.
|
|
|
|
- finally it double checks sys.path again and will fail if there are still
|
|
paths from the old environment present.
