loop->call(...) is similar to the old logic->Call(...), but is smart
about the current thread: if called from within the event loop it simply
runs the argument directly, otherwise it queues it.
Similarly most of the other event loop calls are also now thread-aware:
for example, `call_later(...)` can queue the job directly when called if
in the event loop rather than having to double-queue through the even
loop (once to call, then inside the call to initiate the time).
- removes all the llarp_ev_* functions, replacing with methods/classes/functions in the llarp
namespace.
- banish ev/ev.h to the void
- Passes various things by const lvalue ref, especially shared_ptr's that don't need to be copied
(to avoid an atomic refcount increment/decrement).
- Add a llarp::UDPHandle abstract class for UDP handling
- Removes the UDP tick handler; code that needs tick can just do a separate handler on the event
loop outside the UDP socket.
- Adds an "OwnedBuffer" which owns its own memory but is implicitly convertible to a llarp_buffer_t.
This is mostly needed to take over ownership of buffers from uvw without copying them as,
currently, uvw does its own allocation (pending some open upstream issues/PRs).
- Logic:
- add `make_caller`/`call_forever`/`call_every` utility functions to abstract Call wrapping and
dependent timed tasks.
- Add inLogicThread() so that code can tell its inside the logic thread (typically for
debugging assertions).
- get rid of janky integer returns and dealing with cancellations on call_later: the other methods
added here and the event loop code remove the need for them.
- Event loop:
- redo everything with uvw instead of libuv
- rename EventLoopWakeup::Wakeup to EventLoopWakeup::Trigger to better reflect what it does.
- add EventLoopRepeater for repeated events, and replace the code that reschedules itself every
time it is called with a repeater.
- Split up `EventLoop::run()` into a non-virtual base method and abstract `run_loop()` methods;
the base method does a couple extra setup/teardown things that don't need to be in the derived class.
- udp_listen is replaced with ev->udp(...) which returns a new UDPHandle object rather that
needing gross C-style-but-not-actually-C-compatible structs.
- Remove unused register_poll_fd_(un)readable
- Use shared_ptr for EventLoopWakeup rather than returning a raw pointer; uvw lets us not have to
worry about having the event loop class maintain ownership of it.
- Add factory EventLoop::create() function to create a default (uvw-based) event loop (previously
this was one of the llarp_ev_blahblah unnamespaced functions).
- ev_libuv: this is mostly rewritten; all of the glue code/structs, in particular, are gone as
they are no longer needed with uvw.
- DNS:
- Rename DnsHandler to DnsInterceptor to better describe what it does (this is the code that
intercepts all DNS to the tun IP range for Android).
- endpoint:
- remove unused "isolated network" code
- remove distinct (but actually always the same) variables for router/endpoint logic objects
- llarp_buffer_t
- make constructors type-safe against being called with points to non-size-1 values
- tun packet reading:
- read all available packets off the device/file descriptor; previously we were reading one packet
at a time then returning to the event loop to poll again.
- ReadNextPacket() now returns a 0-size packet if the read would block (so that we can implement
the previous point).
- ReadNextPacket() now throws on I/O error
- Miscellaneous code cleanups/simplifications
when retransmissions happen, they will be executed in a deterministic order by their delivery id.
this reduces the jitter from delayed message delivery on link layer as with an unordered map the order of iteration is "random",
so when we iterate all messages for retransmission we do it lowest id first (the messages queued first).
- Previous android java and jni code updated to work, but with much love
still needed to make it work nicely, e.g. handling when the VPN is
turned off.
- DNS handling refactored to allow android to intercept and handle DNS
requests as we can't set the system DNS to use a high port
(and apparently Chrome ignores system DNS settings anyway)
- add packet router structure to allow separate handling of specific
intercepted traffic, e.g. UDP traffic to port 53 gets handled by our
DNS handler rather than being naively forwarded as exit traffic.
- For now, android lokinet is exit-only and hard-coded to use exit.loki
as its exit. The exit will be configurable before release, but
allowing to not use exit-only mode is more of a challenge.
- some old gitignore remnants which were matching to things we don't
want them to (and are no longer relevant) removed
- some minor changes to CI configuration
- Remove SIIT from method names & comments because we're doing IPv4
mapped addresses (::ffff:0:0/96) rather than actual SIIT
(::ffff:0:0:0/96).
- add constructor taking a string+numeric port (and then don't allow a
port in the string).
- simplify IP string parsing by using parse_int()
- replace addrIsV4 with call to ipv6_is_mapped_ipv4 (this also fixes a
bug where addrIsV4 was not checking for leading 0s and so could return
true for a public IPv6 that happened to have ffff in the wrong spot).

So apparently dnsConfig in Router was never set.
Router::networkConfig was set, but only used in the function
which set it and otherwise only passed to another function once.
dnsConfig was only used in one place.
both member variables have been removed in favor of just
referencing Router::m_Config.

* Should fix some windows service issues
* fix return condition inversion
* Add some Trace level logging
also make the logger actually respect the log level you set.
* event loop should not queue things to itself...
at present, logic thread queue continues until it is empty, so
queueing things onto itself is just wasteful.
* call_later(foreach thing) is better than foreach thing (call later)
also if you already queued those things but they have not happened yet,
there is no sense to queue them to happen again.
* do not queue read on write finish, only on read finish
* failure to start DNS server should be proper startup failure.
without the DNS server working lokinet is...kinda pointless, right?
* format
* don't queue stuff to logic thread if in logic thread
the thing that clears the queue...clears it. So you're just delaying and adding overhead.
* windows unbound thread sleep instead of just busy-waiting
also clang-format decided I can't have a blank line for some reason...
* fix unbound async worker on windows
* add conf.d directory for config overrides
* refactor llarp::Config
* add explicit constructor with datadir as parameter
* have all config files be passed as std::optional
* make Config::LoadDefault private and use std::optional in Config::Load to remove ambiguity
* update rest of codebase to reflect above changes
* fix pybind
* rename bootstrap config skipBootstrap to seednode as it's more descriptive
* make seednode configurable
* make pybind layer compile
* make pybind layer run
If not using an exit, messing with the routing table is not good.
As such, the ability to keep track of routes we *might* want is good,
but the ability to set/unset those routes is necessary, to correspond
to enabling/disabling exit functionality.
* add some dns txt records for stuff we want to expose
* fix txt records
* txt records for snode info
* dont send cname as it mangles the response
* check for 3 parts not 3 characters
* Config file API/comment improvements
API improvements:
=================
Make the config API use position-independent tag parameters (Required,
Default{123}, MultiValue) rather than a sequence of bools with
overloads. For example, instead of:
conf.defineOption<int>("a", "b", false, true, 123, [] { ... });
you now write:
conf.defineOption<int>("a", "b", MultiValue, Default{123}, [] { ... });
The tags are:
- Required
- MultiValue
- Default{value}
plus new abilities (see below):
- Hidden
- RelayOnly
- ClientOnly
- Comment{"line1", "line2", "line3"}
Made option definition more powerful:
=====================================
- `Hidden` allows you to define an option that won't show up in the
generated config file if it isn't set.
- `RelayOnly`/`ClientOnly` sets up an option that is only accepted and
only shows up for relay or client configs. (If neither is specified
the option shows up in both modes).
- `Comment{...}` lets the option comments be specified as part of the
defineOption.
Comment improvements
====================
- Rewrote comments for various options to expand on details.
- Inlined all the comments with the option definitions.
- Several options that were missing comments got comments added.
- Made various options for deprecated and or internal options hidden by
default so that they don't show up in a default config file.
- show the section comment (but not option comments) *after* the
[section] tag instead of before it as it makes more sense that way
(particularly for the [bind] section which has a new long comment to
describe how it works).
Disable profiling by default
============================
We had this weird state where we use and store profiling by default but
never *load* it when starting up. This commit makes us just not use
profiling at all unless explicitly enabled.
Other misc changes:
===================
- change default worker threads to 0 (= num cpus) instead of 1, and fix
it to allow 0.
- Actually apply worker-threads option
- fixed default data-dir value erroneously having quotes around it
- reordered ifname/ifaddr/mapaddr (was previously mapaddr/ifaddr/ifname)
as mapaddr is a sort of specialization of ifaddr and so makes more
sense to come after it (particularly because it now references ifaddr
in its help message).
- removed peer-stats option (since we always require it for relays and
never use it for clients)
- removed router profiles filename option (this doesn't need to be
configurable)
- removed defunct `service-node-seed` option
- Change default logging output file to "" (which means stdout), and
also made "-" work for stdout.
* Router hive compilation fixes
* Comments for SNApp SRV settings in ini file
* Add extra blank line after section comments
* Better deprecated option handling
Allow {client,relay}-only options in {relay,client} configs to be
specified as implicitly deprecated options: they warn, and don't set
anything.
Add an explicit `Deprecated` tag and move deprecated option handling
into definition.cpp.
* Move backwards compat options into section definitions
Keep the "addBackwardsCompatibleConfigOptions" only for options in
sections that no longer exist.
* Fix INI parsing issues & C++17-ify
- don't allow inline comments because it seems they aren't allowed in
ini formats in general, and is going to cause problems if there is a
comment character in a value (e.g. an exit auth string). Additionally
it was breaking on a line such as:
# some comment; see?
because it was treating only `; see?` as the comment and then producing
an error message about the rest of the line being invalid.
- make section parsing stricter: the `[` and `]` have to be at the
beginning at end of the line now (after stripping whitespace).
- Move whitespace stripping to the top since everything in here does it.
- chop off string_view suffix/prefix rather than maintaining position
values
- fix potential infinite loop/segfault when given a line such as `]foo[`
* Make config parsing failure fatal
Load() LogError's and returns false on failure, so we weren't aborting
on config file errors.
* Formatting: allow `{}` for empty functions/structs
Instead of using two lines when empty:
{
}
* Make default dns bind 127.0.0.1 on non-Linux
* Don't show empty section; fix tests
We can conceivably have sections that only make sense for clients or
relays, and so want to completely omit that section if we have no
options for the type of config being generated.
Also fixes missing empty lines between tests.

If you specify upstream= then you get no upstream, if you give one then
you use that instead of the default, but you can still list multiple.
unbound doesn't support an upstream port, so bail if the user gives a
non-port-53 response.
0.7 supported both public-address and public-ip, but only the former was
being allowed in 0.8.
This makes `public-ip=...` work again, and makes it the canonical option
(because it makes a bit more sense than address when we also have the
public-port parameter), while making `public-address=` accepted with a
deprecation warning.
Also adds default descriptions for port and ip for the generated ini.

* Add ignored [dns]no-resolvconf option for deb backwards compat
The debs hack a `#no-resolvconf=1` into the config file in 0.7 to allow
a user to disable resolvconf setup during startup by uncommenting it.
That doesn't work anymore since 0.8 errors on invalid config options, so
add it as an ignored option so that 0.7 deb config files can still be
compatible.
