[tor/release-0.4.3] Use __attribute__((fallthrough)) rather than magic GCC comments.
by nickm＠torproject.org 06 May '20

06 May '20

commit 79ff2b6aab13011197e8342763de3cae48700dfb Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed May 6 10:45:48 2020 -0400 Use __attribute__((fallthrough)) rather than magic GCC comments. GCC added an implicit-fallthrough warning a while back, where it would complain if you had a nontrivial "case:" block that didn't end with break, return, or something like that. Clang recently added the same thing. GCC, however, would let you annotate a fall-through as intended by any of various magic "/* fall through */" comments. Clang, however, only seems to like "__attribute__((fallthrough))". Fortunately, GCC accepts that too. A previous commit in this branch defined a FALLTHROUGH macro to do the right thing if GNUC is defined; here we replace all of our "fall through" comments with uses of that macro. This is an automated commit, made with the following perl one-liner: #!/usr/bin/perl -i -p s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i; (In order to avoid conflicts, I'm applying this script separately to each maint branch. This is the 0.4.1 version.) --- src/app/config/confparse.c | 8 +++--- src/core/or/channeltls.c | 2 +- src/core/or/circuitbuild.c | 2 +- src/core/or/circuitlist.c | 2 +- src/core/or/circuituse.c | 2 +- src/core/or/connection_edge.c | 6 ++-- src/core/or/crypt_path.c | 2 +- src/core/or/onion.c | 2 +- src/core/or/policies.c | 2 +- src/core/or/reasons.c | 2 +- src/core/or/relay.c | 2 +- src/core/or/scheduler.c | 4 +-- src/core/or/sendme.c | 2 +- src/core/proto/proto_socks.c | 4 +-- src/ext/csiphash.c | 14 ++++----- src/ext/ed25519/donna/modm-donna-32bit.h | 48 +++++++++++++++---------------- src/ext/ed25519/donna/modm-donna-64bit.h | 24 ++++++++-------- src/feature/client/entrynodes.c | 2 +- src/feature/control/control_cmd.c | 2 +- src/feature/dirclient/dirclient.c | 2 +- src/feature/dirparse/parsecommon.c | 2 +- src/feature/relay/dns.c | 2 +- src/feature/rend/rendclient.c | 2 +- src/lib/crypt_ops/crypto_digest_nss.c | 26 ++++++++--------- src/lib/crypt_ops/crypto_digest_openssl.c | 10 +++---- src/test/test_socks.c | 2 +- 26 files changed, 89 insertions(+), 89 deletions(-) diff --git a/src/app/config/confparse.c b/src/app/config/confparse.c index 729e7a447..efa0c19fa 100644 --- a/src/app/config/confparse.c +++ b/src/app/config/confparse.c @@ -179,7 +179,7 @@ config_assign_value(const config_format_t *fmt, void *options, *(int *)lvalue = CFG_AUTO_PORT; break; } - /* fall through */ + FALLTHROUGH; case CONFIG_TYPE_INT: case CONFIG_TYPE_UINT: i = (int)tor_parse_long(c->value, 10, @@ -577,7 +577,7 @@ config_get_assigned_option(const config_format_t *fmt, const void *options, escape_val = 0; break; } - /* fall through */ + FALLTHROUGH; case CONFIG_TYPE_CSV_INTERVAL: case CONFIG_TYPE_INTERVAL: case CONFIG_TYPE_MSEC_INTERVAL: @@ -588,7 +588,7 @@ config_get_assigned_option(const config_format_t *fmt, const void *options, tor_asprintf(&result->value, "%d", *(int*)value); escape_val = 0; /* Can't need escape. */ break; - case CONFIG_TYPE_UINT64: /* Fall through */ + case CONFIG_TYPE_UINT64: FALLTHROUGH; case CONFIG_TYPE_MEMUNIT: tor_asprintf(&result->value, "%"PRIu64, (*(uint64_t*)value)); @@ -605,7 +605,7 @@ config_get_assigned_option(const config_format_t *fmt, const void *options, escape_val = 0; break; } - /* fall through */ + FALLTHROUGH; case CONFIG_TYPE_BOOL: result->value = tor_strdup(*(int*)value ?

[tor/release-0.4.3] Use __attribute__((fallthrough)) rather than magic GCC comments.
by nickm＠torproject.org 06 May '20

06 May '20

commit 28ac17f433d954355494989983005498c7fe9292 Author: Nick Mathewson <nickm(a)torproject.org> Date: Wed May 6 10:45:48 2020 -0400 Use __attribute__((fallthrough)) rather than magic GCC comments. GCC added an implicit-fallthrough warning a while back, where it would complain if you had a nontrivial "case:" block that didn't end with break, return, or something like that. Clang recently added the same thing. GCC, however, would let you annotate a fall-through as intended by any of various magic "/* fall through */" comments. Clang, however, only seems to like "__attribute__((fallthrough))". Fortunately, GCC accepts that too. A previous commit in this branch defined a FALLTHROUGH macro to do the right thing if GNUC is defined; here we replace all of our "fall through" comments with uses of that macro. This is an automated commit, made with the following perl one-liner: #!/usr/bin/perl -i -p s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i; (In order to avoid conflicts, I'm applying this script separately to each maint branch.
