-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I've been trying to get to grips with the hidden service code, and I have a question that I was hoping someone on the list could answer. The constant REND_HID_SERV_DIR_REQUERY_PERIOD is defined as 15 * 60 (15 minutes) in rendclient.c, with the comment "The period for which a hidden service directory cannot be queried for the same descriptor ID again." As far as I can tell, the purpose of this constant is to prevent a client from repeatedly asking an HS directory for a descriptor that the directory doesn't have. However, when a descriptor fetch fails and there's no reusable cached descriptor, rend_client_desc_trynow(query) calls rend_client_note_connection_attempt_ended(onion_address), which calls purge_hid_serv_from_last_hid_serv_requests(onion_address), which (as far as I can tell) forgets which HS directories have been tried for the descriptor, allowing the same directories to be tried again before REND_HID_SERV_DIR_REQUERY_PERIOD elapses. So what's the effect of REND_HID_SERV_DIR_REQUERY_PERIOD? Thanks for any guidance, Michael -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAEBCAAGBQJThJI1AAoJEBEET9GfxSfMHxwH/3DH2ZpWsmjfu8wX/Zaw2m1T 5NBYhrzpQqJ5C3doVd5cSsCuZINQOG/kHFda3HAf4a0UwANkGZQzSKiB78IXL/VG yEVts1ZpDEF3rtGgnQMBnFQ9JChNzYRuJ5uT+EFJBjW9fgWVuh+8KugNev9wLiR8 V8ayDaekZxUaT11+qEqS974IRI1wWVIzUvGFylMsCsuf/NAKkUalXscOOT3ckKUN g2b1M5f38uzpFqdvRtTIgL/p0dS3JtrrGcuYnwD2+THzeAQpIHGuFPxnbjoauCBd HwyGCo0v3UKr4e00YSKlhJBAZjB2Y41jwi5vasp7IefFvsuVOXfcc8b4BP5Syyk= =d/B4 -----END PGP SIGNATURE-----
