fix: Send pre-message after successful sending of post-message (#8063 )

On the receiving side, download post messages w/o known pre-message after 30s to protect from lost messages. This isn't easy to test in Rust though because the `smtp` sending code requires an SMTP connection, so it's only tested (by already existing tests) that messages are queued in the right order. Another problem is that the `smtp` sending logic doesn't try to send any messages following a failed-to-send message until the retry limit is reached, so if there's smth wrong with a post-message, other unrelated messages are delayed, but this problem has already existed.

This isn't easy to test in Rust though because the `smtp` sending code requires an SMTP connection, so it's only tested (by already existing tests) that messages are queued in the right order. Another problem is that the `smtp` sending logic doesn't try to send any messages following a failed-to-send message until the retry limit is reached, so if there's smth wrong with a post-message, other unrelated messages are delayed, but this problem has already existed.	2026-05-09 11:51:21 -04:00

Hash of Cargo.{toml,lock} is part of the cache key, so for dependency updating PRs the cache key is new. Such PRs rebuild everything from scratch, which is a separate problem. Storing such cache from PR is however not useful because most of the time dependency updating PR is going to be rebased again before merging as Dependabot PRs are opened in a batch and then merged one by one while Dependabot rebases remaining PRs.	2026-05-04 11:21:33 +00:00
