* Add more useful usage instructions for all subcommands
Fixes#3875.
* Update usage instructions
Address PR comments. Fixes#3875.
* Fix line length
* Suffix usage lines with two empty lines
Per review, this brackets all usage text in 2 newlines to match existing
text.
Creates documentation boilerplate for certbot-dns-route53 using
tools/sphinx-quickstart.sh.
Adds trivial `authenticator.rst` and `dns_route53.rst` files.
When our Apache plugin is unable to determine which virtual host to use in
non-interactive mode, it raises an error about vhost ambiguity with
instructions on how to fix the problem. These instructions stated that we
require one vhost per file which is no longer accurate since #4706 so I removed
this part of the error message.
Without this change, the Route53 plugin is listed twice when running
Certbot interactively (once under the old name, once under the new name).
This change ensures only the new name is shown, while maintaining hidden
backwards compatibility with the old name.
* add TLSSNI01DualNetworkedServers
* use DualNetworkedServers in certbot/plugins/standalone.py
also, make both servers run on the same port.
* make probe_sni connect on ipv6 and ipv4 using None
* mimic BSD-like conditions to get test coverage
* test ServerManager taking into account BSD systems
* pass tests even if python is compiled without ipv6 support
This change renames certbot-route53 to certbot-dns-route53 and updates
the package's setup.py file to maintain backwards compatibility.
Testing Done:
* Run `certbot` with `-a certbot-route53:auth`, verify the plugin runs.
* Run `certbot` with `--dns-route53`, verify the plugin runs.
* Remove dependency on git from pip_install.sh.
Using git allowed this file to continue to work even if it was moved to another
directory. This slight increase in robustness wasn't worth it though as it
broke our development Dockerfile (see #4703), the certbot website's Dockerfile
(see certbot/website#226), and our test farm tests (see
certbot/tests/letstest/scripts/test_apache2.sh for an example that calls
tools/venv.sh without installing git). Rather than continuing to find and patch
these things, let's just allow this script to fail if it's moved rather than
propagating the git dependency all over the place.
* Add readlink.py.
This is the equivalent of `readlink -f` on many Linux systems. This is useful
as there are often differences in readlink on different platforms.
* Use readlink.py in pip_install.sh.
This allows us to work around differences in readlink on macOS.
The program readlink used to be used in integration tests so an environment
variable was used to handle differences in the executable on different systems.
This command is no longer used though so the variable can be removed.
