To celebrate Server Side Swift Conference 2025 I am proposing a fix to the long-standing issue where import of Swift signing GPG keys fails.
As identified in multiple bug reports, the root cause is that
downloadToolfetching the keys from the swift.org website actually stores gzipped file into a temporary directory, andgpg --importis unable to cope with that.Some people suggested that this may be a problem with the CDN sending
deflateencoding randomly, so I am proposing a robust fix that invokeszcaton the downloaded file and then pipes it intogpg --importviastdin.Tried on couple runs in my private repositories and it seems to work reliably.
Narrator's edit: It did not work reliably. Turns out that sometimes the keys are in plaintext, and sometimes gzipped, we can only speculate why, so I added a more robust logic to handle both cases.
Closes #759, #739, #694, #591, #520, #419.
