This PR fixes #4362 by introducing a new boolean to catch panics in the rayon thread pool. The boolean is read after performing the operations in rayon, and the indexation process is stopped. This first version doesn't expose the panic message but marks the task as failed.
The current implementation exposes a
ThreadPoolNoAbort
wrapper. Therayon::ThreadPool
has been wrapped to check that nothing went wrong after running theThreadPool::install
function. An atomic boolean and somestore/load
logic make the system work efficiently.Before, Meilisearch was completely crashing...
Now, it handles the panics correctly and marks the task as failed.
