Fixes#6955.
This updates the Fedora version used in our test farm tests to Fedora 30. The AMI ID comes from https://alt.fedoraproject.org/cloud/ where it is listed as their standard HVM AMI for the region we use us-east-1 (US East (N. Virginia)).
Unfortunately, there were a lot of small changes required for this. The big reason for this is on Fedora, there isn't a Python 2 executable installed. In fact, there's not even an executable named python. It's just python3. Rather than installing another Python in each test, I wrote a script that the test scripts can share to figure out the different paths and names that should be used in their script. (This isn't used in test_sdists.sh because the logic is a little different.)
Other changes here worth flagging are:
I changed the name of the variable RUN_PYTHON3_TESTS in test_leauto_upgrades.sh to RUN_RHEL6_TESTS. The tests that are run when this variable is set test the upgrade from Python 2 to Python 3 on RHEL 6. I think this new name is much better now that we also have Fedora running Python 3.
I made tools/simple_http_server.py work on Python 3.
You can see tests passing with these changes at https://travis-ci.com/certbot/certbot/builds/113821476. I also ran test_tests.sh and they passed.
* Update to Fedora 30 in test farm tests.
Fedora 28 is likely to reach its EOL soon.
* Add set_python_envvars.sh.
* Fix test_apache2.sh on python3 only distros.
* Fix test_leauto_upgrades.sh on python3 systems.
* Fix certonly_standalone tests with python3 only
* Fix test_sdists.sh on python3 only distros.
* Make simple_http_server.py work on Python 3.
* add comments
Fixes#6861.
_venv_common.py is no longer executable. The reason for this is the venv creation logic is now different between Python 2 and Python 3. We could add code that branches on the Python version running the script, but I personally think that's unnecessary.
--setuptools and --no-site-packages is no longer passed to virtualenv either. These flags were made noops in virtualenv 1.10 and 1.7 respectively, but all of CentOS 6, 7, Debian 8+, and Ubuntu 14.04+ have new enough versions of virtualenv where these flags are no longer necessary. They are not even accepted as flags to Python 3's venv module.
Use of VENV_ARGS from test_sdists.sh was also removed because that environment variable hasn't done anything in a while.
I ran test farm tests on test_apache2.sh and test_sdists.sh with these changes and they passed.
* Fixes#6861.
* _venv_common is no longer executable.
* prevent regressions of #5082
* Fix test_leauto_upgrades.sh
test_leauto_upgrades.sh has been incorrectly been succeeding because while peep
doesn't work with newer versions of pip and letsencrypt-auto would crash,
the output included the version number so we reported the test as passing.
This updates letsencrypt-auto to the oldest version that still works for the
purpose of the test and sets pipefail so errors are properly reported.
* Test symlink creation in test_leauto_upgrades.sh
* Pin dependencies in test_sdists.sh.
* Fix permissions errors in test_tests.sh
* add get_certbot_version.sh
* Use get_certbot_version.sh in build.py
* make test_leauto_upgrades.sh more robust
* auto upgrades break tests
* OCSP experimental is not needed anymore
* Add test_sdists.sh
* Use LE_AUTO_VERSION, not repo version
* install OS deps earlier
* use readlink not realpath
* undo changes to build.py
* Factor out version code from build.py
* Use version.py in test_sdists
* Remove get_certbot_version
* workaround setuptools breakage
