This change establishes Python 3 compatibility for the major part of
Gerrit build tool chain. Only two scripts remain non Python 3
compatible:
* Documentation/replace_macros.py
* tools/bzl/license-map.py
Those scripts explicitly invoked with python2 version.
Test Plan:
a. Python 2.7
* Switch to system where /usr/bin/python points to Python 2.7
* bazel build release
* bazel test //...
* tools/eclipse/project.py
b. Python 3.6
* Switch to system where /usr/bin/python points to Python 3.6
* bazel build release
* bazel test //...
* tools/eclipse/project.py
Pre-requisites for the test plan:
In case bazel action and repository caching is activated on the SUT, the
caches would need to be wiped out, to make sure that the complete build
tool chain was tested. On my system I had to run these commands:
* bazel clean --expunge_async
* rm -rf ~/.gerritcodereview/buck-cache/downloaded-artifacts/*
* rm -rf ~/.gerritcodereview/bazel-cache/cas/*
* rm -rf ~/.gerritcodereview/bazel-cache/repository/*
