From 0c15bf18d5163ef7f964b8f2f012934bdf954895 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20Matczuk?= Date: Thu, 16 Apr 2026 10:12:44 +0200 Subject: [PATCH] sql: fix data race in TestIntegrationCosmosDB Skip TestIntegrationCosmosDB when running with the race detector. The gocosmos driver depends on gjrc v0.2.2 which has a data race in GjrcResponse.Body: it uses broken double-checked locking where the outer nil check reads a shared field without the mutex while a background goroutine (spawned eagerly by gjrc.buildResponse) writes it under the mutex. This is a bug in the third-party library that affects every gocosmos REST call and cannot be worked around. gjrc v0.2.2 is the latest available version as of this commit.
