updateFallbackDirs.py.
Closes ticket 20878.
- Require fallback directories to have the same address and port for
4 months. (4 months is a tradeoff between the expected time between
major Tor releases, which is 6 months, and the number of relays with
enough stability.) Relays whose OnionOO stability timer is reset on
restart by bug 18050 should upgrade to Tor 0.2.8.7 or later, which has
a fix for this issue.
Closes ticket 20880; removes short-term fix in e220214 in
7 dayss. (Due to the number of relays with enough stability.) Relays
whose OnionOO stability timer is reset on restart by bug 18050 should
upgrade to Tor 0.2.8.7 or later, which has a fix for this issue.
Closes ticket 20880; maintains short-term fix in e220214 in
tor-0.2.8.2-alpha.
- Make it easier to change the output sort order of fallbacks.
Closes ticket 20822.
