…33742) Currently each outgoing repair request will attempt to establish a connection if one does not already exist. This is very wasteful and consumes many tokio tasks if the remote node is down or unresponsive. The commit decouples routing packets from establishing connections by adding a buffering channel for each remote address. Outgoing packets are always sent down this channel to be processed once the connection is established. If connecting attempt fails, all packets already pushed to the channel are dropped at once, reducing the number of attempts to make a connection if the remote node is down or unresponsive. (cherry picked from commit 7aa0fae)

Backporting this PR because repair over QUIC is shipped in v1.17 but without this patch it will not work properly. |
