The zulip and zulip_botserver packages specify mock as a runtime
dependency, which is only needed for testing during development.
So, it made more sense to move it to requirements.txt so that
it can be installed by ./tools/provision during development.
This commit removes the following:
* This script's dependency on gitpython, it is not maintained actively.
* The ability to push changes in this and the main zulip/ repo. Doing
so automatically was turning out to be cumbersome and buggy and
doing it manually doesn't take significantly longer anyway.
* The ability to automatically increment PROVISION_VERSION in
zulip/version.py. Again, this was too buggy and it doesn't take
much longer to just increment it by hand.
Removing the above features made the script a lot easier to maintain
and read.
This commit adds a script to automate the PyPA release of the
zulip, zulip_bots and zulip_botserver packages.
The tools/release-packages script would take care of uploading
the packages to PyPA, and push commits to both repos updating the
package versions. If you have commit access to the repos, you
can --push upstream to master. If not, then you can --push
origin to a new branch on your fork and create a PR for those
changes.
Ideally, a release shouldn't take longer than however long it
takes one to type the above command. If you have SSH set up on
GitHub, you won't need to type in your GitHub username and
password. You can also store your PyPA credentials in a file
in your home directory; it isn't very secure, but it saves
time nevertheless.
