commit ba63c4099a491c3f96160005f94cf3a61433c145 Author: David Goulet dgoulet@torproject.org Date: Mon Sep 25 16:47:16 2017 -0400
hs-v3: Don't cleanup intro point in has_closed()
The hs_service_intro_circ_has_closed() was removing intro point objects if too many retries.
We shouldn't cleanup those objects in that function at all but rather let cleanup_intro_points() do its job and clean it properly.
This was causing an issue in #23603.
Furthermore, this moves the logic of remembering failing intro points in the cleanup_intro_points() function which should really be the only function to know when to cleanup and thus when an introduction point should be remembered as a failed one.
Fixes #23603
