commit c529b3f8f1d882b29c6b505de1a61d24c6a0943c Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue Oct 8 16:05:04 2019 -0400 Make the command-line parser understand "commands". Previously these were implemented with a search in options_init_from_torrc(), but that led to each option being declared more than needed: once to say that it was a valid option, and once to say what it meant. --- src/app/config/config.c | 80 ++++++++++++++++++++++----------------- src/app/config/config.h | 4 ++ src/app/config/tor_cmdline_mode.h | 4 +- src/app/main/main.c | 1 + src/app/main/ntmain.c | 1 + 5 files changed, 55 insertions(+), 35 deletions(-) diff --git a/src/app/config/config.c b/src/app/config/config.c index 74cd70ad3..734bd0f92 100644 --- a/src/app/config/config.c +++ b/src/app/config/config.c @@ -2457,6 +2457,8 @@ static const struct { const char *name; /** Does this option accept an argument? */ takes_argument_t takes_argument; + /** If not CMD_RUN_TOR, what should Tor do when it starts? */ + tor_cmdline_mode_t command; } CMDLINE_ONLY_OPTIONS[] = { { .name="-f", .takes_argument=ARGUMENT_NECESSARY }, @@ -2464,31 +2466,44 @@ static const struct { { .name="--defaults-torrc", .takes_argument=ARGUMENT_NECESSARY }, { .name="--hash-password", - .takes_argument=ARGUMENT_NECESSARY }, + .takes_argument=ARGUMENT_NECESSARY, + .command=CMD_HASH_PASSWORD }, { .name="--dump-config", - .takes_argument=ARGUMENT_OPTIONAL }, - { .name="--list-fingerprint" }, - { .name="--keygen" }, + .takes_argument=ARGUMENT_OPTIONAL, + .command=CMD_DUMP_CONFIG }, + { .name="--list-fingerprint", + .command=CMD_LIST_FINGERPRINT }, + { .name="--keygen", + .command=CMD_KEYGEN }, { .name="--key-expiration", - .takes_argument=ARGUMENT_OPTIONAL }, + .takes_argument=ARGUMENT_OPTIONAL, + .command=CMD_KEY_EXPIRATION }, { .name="--newpass" }, { .name="--no-passphrase" }, { .name="--passphrase-fd", .takes_argument=ARGUMENT_NECESSARY }, - { .name="--verify-config" }, + { .name="--verify-config", + .command=CMD_VERIFY_CONFIG }, { .name="--ignore-missing-torrc" }, { .name="--quiet" }, { .name="--hush" }, - { .name="--version" }, - { .name="--list-modules" }, - { .name="--library-versions" }, - { .name="-h" }, - { .name="--help" }, - { .name="--list-torrc-options" }, - { .name="--list-deprecated-options" }, + { .name="--version", + .command=CMD_OTHER }, + { .name="--list-modules", + .command=CMD_OTHER }, + { .name="--library-versions", + .command=CMD_OTHER }, + { .name="-h", + .command=CMD_OTHER }, + { .name="--help", + .command=CMD_OTHER }, + { .name="--list-torrc-options", + .command=CMD_OTHER }, + { .name="--list-deprecated-options", + .command=CMD_OTHER }, { .name="--nt-service" }, { .name="-nt-service" }, - { NULL, 0 }, + { .name=NULL }, }; /** Helper: Read a list of configuration options from the command line.
