This PR adds the following documentation improvements to fix https://github.com/certbot/certbot/issues/7958:
- Simplify building external plugins
- Separate out certbot snap instructions from plugin instructions
- Mention that dnsimple is just an example for the plugin instructions
- Mention remote build for other architectures
- Mention snap doc exists elsewhere in developer guide (`contributing.rst`)
* Set up generate_dnsplugins_all.sh for all files and parametrize snapcraft and postrefreshhook files
* Create constraints file in the generate_dnsplugins_all script
* Separate out plugin and certbot snaps and update instructions
* Add remote build instructions
* Add pointers to the README to contributing.rst
Fixes#8355
During the troubleshooting of #8355, I came to the conclusion that using buildkit was creating the problem. Without it all docker images are built correctly. Initially buildkit was enabled to avoid a building problem in Azure Pipeline, but I also found in my recent tests that this problem was not there anymore.
You can find more details about the troubleshooting and reasoning in #8355.
As a consequence, I disable the usage of buildkit in this PR which will solve the issue.
Fixes#8202
This PR adds an Azure Pipeline job to execute certbot plugins --prepare for each Docker image created during the CI on amd64.
* Prepare basic integration tests for certbot dockers
* Add a displayName for the integration tests task
* Add timeout to DNS query function calls
* Modify tests to account for new timeout variable
* Add change to CHANGELOG
* Add `dns.exception.Timeout` to exception handler
* Move changelog to 1.10.0
Fixes https://github.com/certbot/certbot/issues/8171.
See the comment at the top of the script to learn how to set things up and run this. Running the script between releases will have no effect on our snaps and it should fail when creating the GitHub release. The latter is described at https://github.com/certbot/certbot/pull/8189#discussion_r466707114.
* Rename create_github_release to finish_release
* Add initial version of snap release automation.
* Handle snapcraft login.
* Catch OSError raised when snapcraft doesn't exist.
* Update documentation.
* Only publish the Certbot snap for now.
* Fix typo.
* Document other exceptions.
* Document assertion
* Add status message before getting revisions.
* Publish all snaps.
With more and more of our wildcard instructions on https://certbot.eff.org telling people to use these plugins, I think we should get ready to move our DNS plugins to the stable channel. This PR removes grade: devel so the snap store doesn't prevent us from doing that when we want to. See #8128 where we did this to the Certbot snap for more info.
You can see the snap tests passing with this change at https://dev.azure.com/certbot/certbot/_build/results?buildId=2797&view=results.
Fixes https://github.com/certbot/certbot/issues/8292.
This uses the same approach that worked well for us in https://github.com/certbot/certbot/pull/7926. I'm sure we could delete more code or refactor things here, but I think we should make the most conservative changes we can to certbot-auto until we can just delete the entire thing.
I ran the full test suite on these changes at https://dev.azure.com/certbot/certbot/_build/results?buildId=2773&view=results and manually tested things on OpenSUSE and it worked as expected. certbot-auto refused to create new installations and refused to update old ones while continuing to allow the old version of Certbot to run.
* Deprecate cb-auto outside of Debian and RHEL.
* Don't deprecate Amazon Linux yet.
Partial fix for #8280
This PR refactors the bash script wrapper for snap (`/certbot.wrapper`) into certbot python codebase. Here are the keypoints of this refactoring:
* the wrapping is applied when `main` function from `certbot._internal.main` is called if environment variable `CERTBOT_SNAPPED` is `True`, which is set during the snap build
* the initial bash script wrapper is removed, simplifying `snap/snapcraft.yaml` by removing the `certbot.wrapper` part
* the dependency to `curl` and `jq` binaries are removed
* the failure during requesting the snapd socket is correctly handled, and displays an informative message in order to correct the situation, as required by #8280
One side note about the modifications done to `app.certbot.command` in `snapcraft.yaml`. Normally calling `bin/certbot` should be sufficient and it is effectively under a normal situation (`core` snap up-to-date). However in the same situation than when the problem occurs in #8280, using `bin/certbot` makes the snap raise an exception about `certbot.main` module that cannot be found.
It seems that when `core` snap is not up-to-date (in Debian for instance with default `snapd` installation), the shebang `/usr/bin/env python3` in the `bin/certbot` wrapper is wrongly resolved to the host Python, instead of the snap Python. It is working as expected if `core` snap is up-to-date. One way to fix that is to keep a bash script wrapper, because in this case, it is the `PATH` value that matters to resolve the Python interpreter, and `PATH` is correctly set up to resolve it from the snap first.
However to keep the simplification provided by the wrapper removal, I prefered to use `bin/python3 $SNAP/bin/certbot` as `command` to explicitly target the correct Python interpreter. Again normally it is not needed because everything is working correctly with a `core` snap up-to-date, but since the root purpose of all of this is to target bad situations, well, it is better to have a snap that is effectively able to start to display the informative message...

This reverts commit feca125437.
Since this change landed, ARM builds for many of the DNS plugins have failed every night. See https://dev.azure.com/certbot/certbot/_build?definitionId=5 or our public Mattermost channel.
I quickly tried to fix this myself and wasn't trivially able to do so. I tried setting `SNAPCRAFT_PYTHON_VENV_ARGS: --system-site-packages` and adding `python3-wheel` as a build dependency, but it didn't work for some reason. The `python3-wheel` package didn't seem to be installed.
I still suspect something like this is the approach we should take, however, I want to fix the failing tests now so things are no longer broken in `master` and those of us on the Certbot team at EFF stop getting spammed with 54 (!!) emails about failed builds from launchpad every night.
Unfortunately, while I was working on this the queue for ARM machines on Launchpad jumped up to an estimated ~20 hour wait, but I confirmed that this fixes the problem by building on an ARM AMI using the instructions at https://github.com/certbot/certbot/blob/master/tools/snap/README.md#use-testing-and-development. If whoever reviews this would like an ARM machine to test on themselves, please let me know.
* add set -e to all bash instances in deploy-stage.yml
* retry uploading snap if we fail
* Add the rest of the set -e calls for bash in azure while we're here
* use retry based on travis_retry
* add set -e to the script: sections that run on macOS/Linux
* actually don't fail on result
* reset result before running command because bash short circuits or conditionals
* remove inapplicable comment
Partial fix for #8256
This PR makes tox calls pipstrap before any commands is executed, and Azure Pipelines calls pipstrap when appropriate (when an actual call to pip is done).
* Invoke pipstrap in tox and during the CI
* Set default value for PYTHON_VERSION and always set python interpreter
* Set Python for snaps_build also
* Fix the build for Windows installer
* Add a warning comment for pinned versions in pipstrap
* Rebuild letsencrypt-auto
* Same version than the installer build
* Let's update to latest pip for installer tests
The ErrorHandler context manager could produce very verbose CLI output
when handling long exception chains (PIP 3134 enhanced reporting).
Rather than logging every exception with its traceback to the CLI, this
commit changes ErrorHandler so that only the final exception in the
chain, without traceback, is logged to the CLI.
This is consistent with a previous change made in the global except
hook (#8000).
* Fixed a few linting warnings for if not x in y.
These should have been caught by pylint, but weren't.
* Replaced "x in y.keys()" with "x in y".
It's much faster, and more Pythonic.
* nginx: reduced CLI logging when reloading nginx
Hides the output of `nginx -s reload` from the CLI, moving it to
debug-level logging.
Additionally, fixes an issue where Certbot did not properly capture the
output of the nginx reload and restart commands.
Fixes#8231
* remove leftover debugging
* reorder CHANGELOG
* don't use bare asserts
random25863.example.org appears in multiple port 80 virtualhosts in the
nginx testdata tarball and also is in the nginx-roundtrip-testdata.
Certbot doesn't handle these properly, which results in random test
failures.
This commit ensures that random25863.example.org only appears in a
single virtualhost and should ensure that the tests pass consistently.
