[stem/master] Replace SocksListenAddress with SocksPort in tests

commit e35286dd97c49c9741497fae9cc544247a6d3c9f Author: Damian Johnson <atagar(a)torproject.org> Date: Wed May 10 11:14:26 2017 -0700 Replace SocksListenAddress with SocksPort in tests Tor deprecated its SocksListenAddress option a while ago and has now dropped it, causing some integ tests to fail. Accounting for this. The option's deprecation was noted in the maual and logs but our tests don't present those so didn't spot the upcoming deprecation.

commit b8abedfeeee3e8d15d952578abb102fbcc56ea04 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 9 08:18:41 2017 -0400 Split MyFamily into user-specified version and normalized version This change prevents a no-longer-supported behavior where we change options that would later be written back to torrc with a SAVECONF. Also, use the "Pointer to final pointer" trick to build the normalized list, to avoid special-casing the first element. --- src/or/config.c | 42 ++++++++++++++++++++---------------------- src/or/or.h | 3 ++- src/test/test_config.c | 2 +- 3 files changed, 23 insertions(+), 24 deletions(-) diff --git a/src/or/config.c b/src/or/config.c index 46057e5..05c6040 100644 --- a/src/or/config.c +++ b/src/or/config.c @@ -395,7 +395,7 @@ static config_var_t option_vars_[] = { V(MaxOnionQueueDelay, MSEC_INTERVAL, "1750 msec"), V(MaxUnparseableDescSizeToLog, MEMUNIT, "10 MB"), V(MinMeasuredBWsForAuthToIgnoreAdvertised, INT, "500"), - V(MyFamily, LINELIST, NULL), + VAR("MyFamily", LINELIST, MyFamily_lines, NULL), V(NewCircuitPeriod, INTERVAL, "30 seconds"), OBSOLETE("NamingAuthoritativeDirectory"), V(NATDListenAddress, LINELIST, NULL), @@ -707,8 +707,9 @@ static int options_transition_affects_workers( const or_options_t *old_options, const or_options_t *new_options); static int options_transition_affects_descriptor( const or_options_t *old_options, const or_options_t *new_options); -static int normalize_nickname_list(config_line_t **lst, const char *name, - char **msg); +static int normalize_nickname_list(config_line_t **normalized_out, + const config_line_t *lst, const char *name, + char **msg); static char *get_bindaddr_from_transport_listen_line(const char *line, const char *transport); static int parse_ports(or_options_t *options, int validate_only, @@ -916,6 +917,7 @@ or_options_free(or_options_t *options) tor_free(options->BridgePassword_AuthDigest_); tor_free(options->command_arg); tor_free(options->master_key_fname); + config_free_lines(options->MyFamily); config_free(&options_format, options); } @@ -3880,13 +3882,14 @@ options_validate(or_options_t *old_options, or_options_t *options, "have it group-readable."); } - if (options->MyFamily && options->BridgeRelay) { + if (options->MyFamily_lines && options->BridgeRelay) { log_warn(LD_CONFIG, "Listing a family for a bridge relay is not " "supported: it can reveal bridge fingerprints to censors.
