* acme: re-populate uri in deactivate_authorization
* Use fresh authorizations in dry runs
--dry-run now deactivates 'valid' authorizations if it encounters them
when creating a new order.
Resolves#5116.
* remove unused code
* typo in local-oldest-requirements
* better error handling
* certbot-ci: AUTHREUSE to 100 + unskip dry-run test
* improve test coverage for error cases
* restore newline to local-oldest-requirements.txt
This is a big part of #7214. It removes all references to TLS-SNI-01 outside of acme (and pytest.ini). Those changes will come in a subsequent PR. I thought this one was getting big enough.
* Remove references to TLS-SNI-01 in Apache plugin
* Remove references to TLS-SNI-01 from certbot-nginx
* Remove references to TLS-SNI from Certbot.
* Remove TLS-SNI reference from docs
* add certbot changelog
* Clarify test behavior
Fixes#5789
This PR is about allowing Certbot to respect the Retry-After HTTP header that an ACME CA server can return to a client POSTing to a challenge, to instruct him and retry the request later.
However, this feature was not easily implementable in the current code of certbot.auth_handler, because the code became really hard to read. In fact, @bmw was thinking that the code was really deceiving, and a lot of supposed functionalities declared in the comments were in fact not implemented or not functional.
So I took the time to understand what was going on, and effectively, most of the code is in fact not usable or not used. Then I did a refactoring against the bare ACME spec about what to do to prepare challenges, instruct the ACME CA server to perform them, then polling regularly the authorization resources until they are decided (valid or invalid).
And of course this implementation takes care of Retry-After ^^
I added a lot of comments in the new implementation, to explain what is going on for a future developer. The workflow I used is relying on the relationships between authorizations and challenges states as described in section 7.1.6 of the ACME spec draft: https://datatracker.ietf.org/doc/draft-ietf-acme-acme/

In response to #5342.
Currently, certbot will execute the operations necessary to validate a challenge even if the challenge has already been validated before against the acme ca server. This can occur for instance if a certificate is asked and issue correctly, then deleted locally, then asked again.
It is a corner case, but it will lead to some heavy operations (like updating a DNS zone, or creating an HTTP server) that are not needed.
This PR corrects this behavior by not executing challenges already validated, and use them directly instead to issue the certificate.
Fixes#5342

An early version of the spec indicated that clients should process issuance
sequentially, following Link rel=next from an account URL to an authz URL, to a
new-cert URL. However, the spec has long since moved to putting these URLs in
the directory.
Certbot nominally supports either; This change consolidates on always using the
directory, simplifying things and making the transition to the latest ACME spec
easier.
