From 442610fa51bb7f09a7eb6a65447d4ce05b45df86 Mon Sep 17 00:00:00 2001 From: Eric Bickle Date: Fri, 8 May 2020 07:35:17 -0700 Subject: [PATCH] Revert "src: fix missing extra ca in tls.rootCertificates" A fix to tls.rootCertificates to have it correctly return the process' current root certificates resulted in non-deterministic behavior when Node.js is configured to use an OpenSSL system or file-based certificate store. The safest action is to revert the change and change the specification for tls.rootCertificates to state that it only returns the bundled certificates instead of the current ones.
