[tor/master] hs-v3: Handle client rendezvous circuit timeout
by asn＠torproject.org 10 Dec '19

commit fc32349adc33ceb0323b7149d661fba71b7f7b98 Author: David Goulet <dgoulet(a)torproject.org> Date: Tue Dec 3 11:08:13 2019 -0500 hs-v3: Handle client rendezvous circuit timeout With v3, the "pending_final_cpath" of a circuit is always NULL which means that for v3, established client rendezvous circuit waiting for the intro point to ACK, will always end up timing out quickly. This can increase the delays to which you connect to a service since in order to succeed, the rendezvous circuit needs to fully established (CIRCUIT_PURPOSE_C_REND_JOINED) within the cutoff of the introduction circuit as well which is these days around 2-3 seconds.
