This event makes us become dormant if we have seen no activity in a
long time.
Note that being any kind of a server, or running an onion service,
always counts as being active.
Note that right now, just having an open stream that Tor
did not open on its own (for a directory request) counts as "being
active", so if you have an idle ssh connection, that will keep Tor
from becoming dormant.
Many of the features here should become configurable; I'd like
feedback on which.
This is part of 28422, so we don't have to call
consider_hibernation() once per second when we're dormant.
This commit does not remove delayed shutdown from hibernate.c: it
uses it as a backup shutdown mechanism, in case the regular shutdown
timer mechanism fails for some reason.
The previous "ALL" role was the OR of a bunch of other roles,
which is a mistake: it's better if "ALL" means "all".
The "NET_PARTICIPANT" role refers to the anything that is actively
building circuits, downloading directory information, and
participating in the Tor network. For now, it is set to
!net_is_disabled(), but we're going to use it to implement a new
"extra dormant mode".
Closes ticket 28336.
Various places in our code try to activate these events or check
their status, so we should make sure they're initialized as early as
possible. Fixes bug 27861; bugfix on 0.3.5.1-alpha.
It differs from the rest of the rephist code in that it's actually
necessary for Tor to operate, so it should probably go somewhere
else. I'm not sure where yet, so I'll leave it in the same
directory, but give it its own file.
Since this is completely core functionality, I'm putting it in
core/mainloop, even though it depends on feature/hibernate. We'll
have to sort that out in the future.
The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.
The parts for handling cell formats should be in src/core/or.
The parts for handling onionskin queues should be in src/core/or.
Only the crypto wrapper belongs in src/core/crypto.
When we close a socket via tor_tls_free(), we previously had no way
for our socket accounting logic to learn about it. This meant that
the socket accounting code would think we had run out of sockets,
and freak out.
Fixes bug 27795; bugfix on 0.3.5.1-alpha.
In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
