From 98e427af9f59f2515ed67b97c64c9fec16fa7211 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Mon, 1 Apr 2024 19:01:18 -0400 Subject: [PATCH] Avoid "unused variable" warning on non-USE_SSL_ENGINE platforms. If we are building with openssl but USE_SSL_ENGINE didn't get set, initialize_SSL's variable "pkey" is declared but used nowhere. Apparently this combination hasn't been exercised in the buildfarm before now, because I've not seen this warning before, even though the code has been like this a long time. Move the declaration to silence the warning (and remove its useless initialization). Per buildfarm member sawshark. Back-patch to all supported branches. --- src/interfaces/libpq/fe-secure-openssl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/interfaces/libpq/fe-secure-openssl.c b/src/interfaces/libpq/fe-secure-openssl.c index c02caafd5f1..47c8e0b2029 100644 --- a/src/interfaces/libpq/fe-secure-openssl.c +++ b/src/interfaces/libpq/fe-secure-openssl.c @@ -909,7 +909,6 @@ initialize_SSL(PGconn *conn) bool have_homedir; bool have_cert; bool have_rootcert; - EVP_PKEY *pkey = NULL; /* * We'll need the home directory if any of the relevant parameters are @@ -1245,6 +1244,7 @@ initialize_SSL(PGconn *conn) /* Colon, but not in second character, treat as engine:key */ char *engine_str = strdup(conn->sslkey); char *engine_colon; + EVP_PKEY *pkey; if (engine_str == NULL) {
