This aligns service node updating logic a bit closer to what happens in
storage server, and should make it a bit more resilient, hopefully
tracking down the (off-Github) reported issue where lokinet sometimes
doesn't see itself as active.
- Initiate a service node list update in the 30s timer lokinet ping
timer (in case we miss a block notify for some reason); although this
is expensive, the next point mitigates it:
- Retrieve the block hash with the SN state update, and feed it back
into the next get_service_nodes call (as "poll_block_hash") so that
oxend just sends back a mostly-empty response when the block hasn't
changed, allowing both oxend and lokinet to skip nearly all of the
work of a service node list update when the block hasn't changed since
the last poll. (This was already partially implemenated--we were
already looking for "unchanged"--but without a block hash to get from
and pass back to oxend we'd never actually get an "unchanged" result).
- Tighten up the service node list handling by moving the "unchanged"
handling into the get_service_nodes response handler: this way the
HandleNewServiceNodeList function is only handling the list but not
the logic as to whether there actually is a new list or not.
It's there for polling, which we aren't doing anymore; we just got the
hash from oxend's push notification, so if it pass it in then we will
always get an "unchanged" result because we're telling oxend that we
already have the data for that hash updated.
This just drops the hash completely because we don't need it anymore.
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once
Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein. Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`
The above does not include system/os headers.
* bump zmq static dep
* lokimq -> oxenmq
* llarp_nodedb -> llarp::NodeDB
* remove all crufty api parts of NodeDB
* make NodeDB rc selection api not suck
* make path builder api not suck
* propagate all above changes so that unit tests work and it all compiles
* initial relay side lns
* fix typo
* add reserved names and refactor test for dns
* lns name decryption
* all wired up (allegedly)
* refact to use service::EncryptedName for LNS responses to include nonce with ciphertext
* fully rwemove tag_lookup_job
* replace lns cache with DecayingHashTable
* check for lns name validity against the following rules:
* not localhost.loki, loki.loki, or snode.loki
* if it contains no dash then max 32 characters long, not including the .loki tld (and also assuming a leading subdomain has been stripped)
* These are from general DNS requirements, and also enforced in
registrations:
* Must be all [A-Za-z0-9-]. (A-Z will be lower-cased by the RPC call).
* cannot start or end with a -
* max 63 characters long if it does contain a dash
* cannot contain -- in the third and fourth characters unless it starts with xn--
* handle timeout in name lookup job by calling the right handler with std::nullopt
* use exceptions when fetching identity key instead of std::optional, will throw on fail
* fix up config options for endpoint auth and add better docs
* add llarp::serive::AuthType enum for controlling what kind of endpoint auth to use
