The previous HTTP back-end was tightly coupled with the threads, which
was very inconvenient. It is now completely decoupled so a new threading
model may be implemented.
Having the data relative to the endpoint in the certificate structure
makes no sense. There is no way to share it across certificates which is
sometimes needed. Also, having the other part of the endpoint data
(mostly nonce and rate limit) in different places makes it difficult to
maintain.
Hence, the endpoint structure has been created. For now it is quite
simple and does not handle every aspects of the endpoint, but this will
be implemented in the future.
The threading architecture was not good at all. It was built around the HTTP part, which isn't flexible enough. Hence, the decision has been made to refactor both of those parts. This will takes 4 steps :
1. remove threads and rate limits (this commit)
2. refactor the HTTP part (the tricky part)
3. reintroduce rate-limits (quite easy)
4. introduce a new threading system (the easiest part)
The PID file is now always written whether or not ACMEd is running in
the foreground. Previously, it was written only when running in the
background.
Fix#7
In some situations, it has been found that a specific ACME server
returns extra characters before and after the JSON, which is therefore
invalid. Although this must be fixed in the server, ACMEd should
gracefully ignore such erroneous characters instead of refusing the
response.
This project provides binaries without any link to Rust or Cargo. It is
just normal binaries that appears to be written in Rust. Therefore, it
does not makes any sense to distribute them in a Rust-specific registry.
Furthermore, such publication would not include the man pages
installation may not respect some distribution-specific policies.
