+From: Ludovic Henry <git@ludovic.dev>

+Subject: [PATCH] tests: wait for the UDS server to accept connections
+
+tests/test_uds.py gives the spawned server a flat 1.5s to import granian,
+bind its socket and start accepting. That budget holds on upstream's x86
+runners and does not on the slower riscv64 ones, where the whole
+tests/test_uds.py http section fails before the socket exists:
+
+    httpx.ConnectError: [Errno 2] No such file or directory
+    httpx.ConnectError: [Errno 111] Connection refused
+
+tests/conftest.py already solves this for the TCP tests by retrying the
+connection until it succeeds; do the same here. The wait returns as soon
+as the socket answers, so faster hardware pays nothing.
+
+Upstream-Status: To upstream [not yet submitted]
