void networkstatus_note_certs_arrived ( const char *  source_dir)

◆ networkstatus_set_current_consensus()

int networkstatus_set_current_consensus ( const char *  consensus,
size_t  consensus_len,
const char *  flavor,
unsigned  flags,
const char *  source_dir 
)

Try to replace the current cached v3 networkstatus with the one in consensus. If we don't have enough certificates to validate it, store it in consensus_waiting_for_certs and launch a certificate fetch.

If flags & NSSET_FROM_CACHE, this networkstatus has come from the disk cache. If flags & NSSET_WAS_WAITING_FOR_CERTS, this networkstatus was already received, but we were waiting for certificates on it. If flags & NSSET_DONT_DOWNLOAD_CERTS, do not launch certificate downloads as needed. If flags & NSSET_ACCEPT_OBSOLETE, then we should be willing to take this consensus, even if it comes from many days in the past.

If source_dir is non-NULL, it's the identity digest for a directory that we've just successfully retrieved a consensus or certificates from, so try it first to fetch any missing certificates.

Return 0 on success, <0 on failure. On failure, caller should increment the failure count as appropriate.

We return -1 for mild failures that don't need to be reported to the user, and -2 for more serious problems.
