commit 5e2294c6fe474558a0f326908064d36d88411da5 Author: Nick Mathewson <nickm@torproject.org> Date: Fri Oct 16 10:03:29 2020 -0400 Fix formats_rsa_ed25519 tests. The "protos" field is mandatory, and so are Ed25519 signatures. Also, remove formats_rsa (the version without Ed25519), since RSA-only relays are no longer supported. --- src/test/test_dir.c | 226 ++-------------------------------------------------- 1 file changed, 7 insertions(+), 219 deletions(-) diff --git a/src/test/test_dir.c b/src/test/test_dir.c index 1e3a594586..f1bb761d72 100644 --- a/src/test/test_dir.c +++ b/src/test/test_dir.c @@ -29,6 +29,7 @@ #include "lib/confmgt/confmgt.h" #include "core/mainloop/connection.h" #include "core/or/relay.h" +#include "core/or/protover.h" #include "core/or/versions.h" #include "feature/client/bridges.h" #include "feature/client/entrynodes.h" @@ -216,6 +217,7 @@ basic_routerinfo_new(const char *nickname, uint32_t ipv4_addr, r1->bandwidthcapacity = bandwidthcapacity; r1->cache_info.published_on = published_on; + r1->protocol_list = tor_strdup(protover_get_supported_protocols()); if (rsa_onion_keypair_out) { *rsa_onion_keypair_out = pk1; @@ -433,13 +435,6 @@ mock_get_configured_ports(void) return mocked_configured_ports; } -static tor_cert_t * -mock_tor_cert_dup_null(const tor_cert_t *cert) -{ - (void)cert; - return NULL; -} - static crypto_pk_t *mocked_server_identitykey = NULL; /* Returns mocked_server_identitykey with no checks. */ @@ -664,211 +659,6 @@ STMT_BEGIN \ tt_str_op(e1->nickname, OP_EQ, r1->nickname); \ STMT_END -/** Run unit tests for router descriptor generation logic for a RSA-only - * router.
