From 1a63cc83c8f79ca4dcb2fb6b93a2c67f7f6889de Mon Sep 17 00:00:00 2001 From: Steven Rhodes Date: Wed, 3 Apr 2024 11:15:02 -0700 Subject: [PATCH] Bump go.mod to 1.21 (#417) * Bump go.mod to 1.21 This should unblock some currently pending updates. Each major Go release is supported until there are two newer major releases and the newest major version is 1.22, so 1.19 has been unsupported for a while. We'd previously tried this six months ago and reverted in https://github.com/Snowflake-Labs/sansshell/pull/357. The cases we had where we wanted an older version should no longer apply. Prometheus libraries (https://github.com/Snowflake-Labs/sansshell/pull/415) are the current dependency where newer versions need newer go compilers. * Address go lint errors * Add in process test
