[Gluster-devel] Python3 build process

With the introduction of default python 3 shebangs and the change in
configure.ac to correct these to py2 if the build is being attempted on
a machine that does not have py3, there are a couple of issues
uncovered. Here is the plan to fix the same, suggestions welcome.
- A configure job is run when creating the dist tarball, and this runs
on non py3 platforms, hence changing the dist tarball to basically have
py2 shebangs, as a result the release-new build job always outputs py
files with the py2 shebang. See tarball in 
- All regression hosts are currently py2 and so if we do not run the py
shebang correction during configure (as we do not build and test from
RPMS), we would be running with incorrect py3 shebangs (although this
seems to work, see . @kotresh can we understand why?)
Plan to address the above is detailed in this bug .
The thought is,
- Add a configure option "--enable-py-version-correction" to configure,
that is disabled by default
- All regression jobs will run with the above option, and hence this
will correct the py shebangs in the regression machines. In the future
as we run on both py2 and py3 machines, this will run with the right
python shebangs on these machines.
- The packaging jobs will now run the py version detection and shebang
correction during actual build and packaging, Kaleb already has put up a
patch for the same .
