alt Hacker News> even if the client had passed a value it would have still done exactly the same thing, as the value of "v" (or anything from the request) is not used in that block
If they passed in any value, they would have entered the block and returned early with the results of FetchPrefixesPendingDeletion.
From the post:
> this was implemented as part of a regularly running sub-task that checks for BYOIP prefixes that should be removed, and then removes them.
They expected to drop into the block of code above, but since they didn't, they returned all routes.
okay so the code which returned everything isn't there
actual explanation: the API server by default returns everything. the client attempted to make a request to return "pending_deletes", but as the request was malformed, the API instead went down the default path, which returned everything. then the client deleted everything.
makes sense now
but is that explanation is even worse
because that means the code path was never tested?
