- Move uvw target to external instead of llarp/CMakeLists.txt
- Add sqlite_orm headers via interface library rather than shoving it
into the global include search path.
- Find sqlite3 as part of the sqlite_orm target deps rather than linking
it separately. (Also don't link it into lokinet-util, which doesn't
appear to actually need it).
- 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
* Update how we build libuv
- Update submoduled libuv to latest stable (1.40.0)
- Don't look for a system libuv if we're under BUILD_STATIC_DEPS
- Add a libuv interface library rather than using globals
- Make the windows build fall back to the submodule if not explicitly
given a LIBUV_ROOT
* Replace ${LIBS} global with `base_libs` interface
This simplifies linking and include handling a bit.
* Remove unneeded header
* Add missing csignal header
(This was previously being pulled in incredibly indirectly via some
stuff that eventually includes some other stuff that eventually included
uv.h)
* Use GNUInstallDirs to get lib dir instead of hard-coding lib
Fixes#1429
This is relatively painless for lokinet as it already had workarounds
during 0.8 dev work for the things macos hated in 10.13.
Dependencies, however, were not being built with the proper macos target
junk, so this fixes that.
* initial work for RC SRVs.
Needs tests for new RC format.
Needs SRVs added to new RC, and associated tests.
* convert rc sign/verify test to catch2, add test for new rc
Also fixes a mistake in new rc serialization
* bump loki-mq submodule
need support for viewing bt deserialize consumer buffer so we
know how much it has consumed.
* fix some behavior errors
need to advance llarp_buffer_t after consuming data from it
only rewind and modify size of llarp_buffer_t in owning context.
* Add test for router contact (de-)serialization
Adds a test that makes a list of RouterContact with mixed
versions and ensures it serializes and deserializes correctly.
* update loki-mq submodule for tuple support
* srv record reply implementation
still need to encode srv records into intro sets / router contacts
as well as decode from them and match against queried service.proto
* inverted condition fix in config code
* SRV record struct (de-)serialization for intro sets
* parsing and using srv records from config (for/in introsets)
* adopt str utils from core and use for srv parsing
* changes to repeat requests
no longer drop repeat requests on the floor, but do not make
an *actual* request for them if one is in progress.
do not call reply hook for each reply for a request, as
each userland request is actually made into several lokinet
requests and this would result in duplicate replies.
* fetch SRVs from introsets for .loki
* make format
* dns and srv fixes, srv appears to be working
Howard Hinnart's date.h is the library that was accepted as C++20
date/calendar support, so this is essentially a backport of C++20 date
time support.
(It does support timezone support, but requires more of the library and
that seems like overkill for what we need; this just prints UTC
timestamps instead, which need only a header-only include).
Step 1 of removing abseil from lokinet.
For the most part this is a drop-in replacement, but there are also a
few changes here to the JSONRPC layer that were needed to work around
current gcc 10 dev snapshot:
- JSONRPC returns a json now instead of an optional<json>. It doesn't
make any sense to have a json rpc call that just closes the connection
with returning anything. Invoked functions can return a null (default
constructed) result now if they don't have anything to return (such a
null value won't be added as "result").
Our current abseil won't build with gcc 10 (its `optional`
implementation appears broken), and spews warnings under slightly older
compilers; updating to the latest stable 2019 branch fixes both issues.
