To remove the dependency on Python 2, existing scripts need to use
python3 rather than python. These commands find those
locations (for impala-python and regular python):
git grep impala-python | grep -v impala-python3 | grep -v impala-python-common | grep -v init-impala-python
git grep bin/python | grep -v python3
This removes or switches most of these locations by various means:
1. If a python file has a #!/bin/env impala-python (or python) but
doesn't have a main function, it removes the hash-bang and makes
sure that the file is not executable.
2. Most scripts can simply switch from impala-python to impala-python3
(or python to python3) with minimal changes.
3. The cm-api pypi package (which doesn't support Python 3) has been
replaced by the cm-client pypi package and interfaces have changed.
Rather than migrating the code (which hasn't been used in years), this
deletes the old code and stops installing cm-api into the virtualenv.
The code can be restored and revamped if there is any interest in
interacting with CM clusters.
4. This switches tests/comparison over to impala-python3, but this code has
bit-rotted. Some pieces can be run manually, but it can't be fully
verified with Python 3. It shouldn't hold back the migration on its own.
5. This also replaces locations of impala-python in comments / documentation /
READMEs.
6. kazoo (used for interacting with HBase) needed to be upgraded to a
version that supports Python 3. The newest version of kazoo requires
upgrades of other component versions, so this uses kazoo 2.8.0 to avoid
needing other upgrades.
The two remaining uses of impala-python are:
- bin/cmake_aux/create_virtualenv.sh
- bin/impala-env-versioned-python
These will be removed separately when we drop Python 2 support
completely. In particular, these are useful for testing impala-shell
with Python 2 until we stop supporting Python 2 for impala-shell.
The docker-based tests still use /usr/bin/python, but this can
be switched over independently (and doesn't impact impala-python)
Testing:
- Ran core job
- Ran build + dataload on Centos 7, Redhat 8
- Manual testing of individual scripts (except some bitrotted areas like the
random query generator)

We're starting to see environments where the system Python ('python') is
Python 3. Updates utility and build scripts to work with Python 3, and
updates check-pylint-py3k.sh to check scripts that use system python.
Fixes other issues found during a full build and test run with Python
3.8 as the default for 'python'.
Fixes a impala-shell tip that was supposed to have been two tips (and
had no space after period when they were printed).
Removes out-of-date deploy.py and various Python 2.6 workarounds.
Testing:
- Full build with /usr/bin/python pointed to python3
- run-all-tests passed with python pointed to python3
- ran push_to_asf.py

ANSI escape sequences do a variety of actions in the
terminal like adding color to compilation warnings.
generate_junitxml.py currently hits an error when trying
to generate JUnitXML for compilation output that contains
ANSI escape sequences.
This changes generate_junitxml.py to strip ANSI
escape sequences from the strings incorporated into
JUnitXML (e.g. the error output of a compiler).
The solution is based off the discussion at:
https://stackoverflow.com/questions/14693701
Testing:
- A case where generate_junitxml.py was failing to
generate JUnitXML now generates valid JUnitXML.
The output still contains all the compiler warnings
and information needed to diagnose the issue.

Python 3 now treats print as a function and requires
the parenthesis in invocation.
print "Hello World!"
is now:
print("Hello World!")
This fixes all locations to use the function
invocation. This is more complicated when the output
is being redirected to a file or when avoiding the
usual newline.
print >> sys.stderr , "Hello World!"
is now:
print("Hello World!", file=sys.stderr)
To support this properly and guarantee equivalent behavior
between python 2 and python 3, all files that use print
now add this import:
from __future__ import print_function
This also fixes random flake8 issues that intersect with
the changes.
Testing:
- check-python-syntax.sh shows no errors related to print

This wraps each command executed by CMake with a wrapper that
generates a JUnitXML file if the command fails. If the command
succeeds, the wrapper does nothing. The wrapper applies to C++
compilation, linking, and custom shell commands (such as
building the frontend via maven). It does not apply to failures
coming from CMake itself. It can be disabled by setting
DISABLE_CMAKE_JUNITXML.
The command output can include Unicode (e.g. smart quotes for
g++), so this also updates generate_junitxml.py to handle
Unicode.
The wrapper interacts poorly with add_custom_command/add_custom_target
CMake commands that use 'cd directory && do_something', so this
switches those locations (in /docker) to use CMake's WORKING_DIRECTORY.
Testing:
- Verified it does not impact a successful build (including with
ccache and/or distcc).
- Verified it generates JUnitXML for C++ and Java compilation
failures.
- Verified it doesn't use the wrapper when DISABLE_CMAKE_JUNITXML
is set.

With python 2.6, the syntax "{}".format(1) doesn't work:
$docker run centos:6 python -c 'print "{}".format(1)'
Traceback (most recent call last):
File "<string>", line 1, in <module>

generate_junitxml was using this incantation and failing.

The original patch for this Jira relied on a third party python lib
for generating Junit XML output, That proved to be limiting because
setting up the necessary virtualenv across a variety of dev and test
scenarios (private dev environment, jenkins.impala.io, and others)
proved to be confusing and messy.
This update to the script maintains the same functionality and the
same interface, but uses only the python standard library. A symlink
has also been added to Impala/bin for convenience.

This patch adds a script to generate junit XML reports for arbitrary
build steps. It's also being used to seed the creation of an internal
python library for Impala development that can be pip installed into
