Sometimes, the fallback generation script doesn't add attributes to the
fallbacks in the list. If this happens, log an error, and avoid selecting
that fallback.
This is a rare issue: it should not change selection behaviour.
Fixes issue #20945.
Exclude relays that have been down for 1 or more days from the fallback
candidate list.
When a relay operator has multiple relays, this prioritises relays that are
up over relays that are down.
Fixes issue #20926.
7 days 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; maintains short-term fix in e220214 in tor-0.2.8.2-alpha.
They broke stem, and breaking application compatibility is usually a
bad idea.
This reverts commit 6e10130e18,
commit 78a13df158, and
commit 62f52a888a.
We might re-apply this later, if all the downstream tools can handle
it, and it turns out to be useful for some reason.
I got confused when I saw my Tor saying it was opening a file
that doesn't exist. It turns out it isn't opening it, it's just
calling open() on it and then moving on when it's not there.
Previously, we had NumEntryGuards kind of hardwired to 1. Now we
have the code (but not the configuarability) to choose randomly from
among the first N primary guards that would work, where N defaults
to 1.
Part of 20831 support for making NumEntryGuards work again.
Since we already had a separate function for getting the universe of
possible guards, all we had to do was tweak it to handle very the
GS_TYPE_RESTRICTED case.
asn found while testing that this function can be reached with
GUARD_STATE_COMPLETE circuits; I believe this happens when
cannibalization occurs.
The added complexity of handling one more state made it reasonable
to turn the main logic here into a switch statement.
Letting the maximum sample size grow proportionally to the number of
guards defeats its purpose to a certain extent. Noted by asn during
code review.
Fixes bug 20920; bug not in any released (or merged) version of Tor.
- Correctly maintain the previous guard selection in choose_guard_selection().
- Print bridge identifier instead of nothing in entry_guard_describe()._
