Setuptools: find SVN revision from a parent directory

问题

In the Python package I'm putting together I'm using the following setup.cfg file:

[egg_info]
tag_build = dev
tag_date = 1
tag_svn_revision = 1

However when I run python setup.py sdist the SVN revision appears as -r0. This is likely because there is no .svn directory where I run the setup script; in fact my tree is

 main_dir/
   .svn/
   branches/
   trunk/
     setup.py
     setup.cfg

How can I tell setuptools to go find the SVN revision number in a parent directory? I still want to keep using my package version number.

回答1:

You can solve the -r0 problem in a different way if you're willing to install another package. Setuptools does not support the SVN metadata since version 10. The functionality has been moved to the setuptools_svn package.

My solution at the moment is to combine this answer and build the version manually like this (minus the shell=True option):

# Hat tip: https://stackoverflow.com/a/1501219/204634
import subprocess

def svnversion():
    p = subprocess.Popen("svnversion", stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    (stdout, stderr) = p.communicate()
    return stdout

_version = '{}-{}'.format(my_pkg_version, svnversion())

Whilst the setup.cfg file contains:

[egg_info]
tag_build = dev
tag_date = 1
