This commit reflects changes to clang-format rules. Unfortunately,
these rule changes create a massive change to the codebase, which
causes an apparent rewrite of git history.

....which is precisely the thing i patch out in libsodium to use CryptoAPI
documented interfaces instead (which fall through to RtlGenRandom() on
such devices _anyway_)
we can just use libsodium directly, i happened to patch it out in libstdc++
as a side effect (since my local toolchain can target any version of windows)
hive.py is currently largely for testing the pybind stuff, so changes to it will likely
be frequent and arbitrary for now.
Added pybind for llarp::path::PathHopConfig, but not every member -- just rc and upstream routerID
Hive now uses std::queue with mutex instead of our lockless queue.
Removed some functions from Hive that will not be necessary as things are being handled from python.
a bunch of routers logging to stdout at the same time is a complete
charlie foxtrot. until we take the time to make logger not a singleton
(and probably make each router able to log to its own file rather than stdout)
just make it not log.
Note: this is very temporary, as the logs will be annoying for testing the
pybind stuff and shouldn't be necessary for debugging it
string_view was implicitly convertible to std::string, but
std::string_view is only explicitly convertible. This makes the
`operator std::string` explicit to be more compatible, and re-adds a
bunch of explicit string casts to the code where needed.
(This also fixes the build if changing the standard to c++17)
They are fairly useless under stdlibc++ because it doesn't have the
required annotations on stl mutexes and locks, so we just get tons of
useless warnings.
Pre-C++17 char_traits::compare isn't constexpr so we can't constexpr the
find/rfind methods that use it.
begin() etc, however, can be constexpr (and need to be for some of the
other constexpr methods here that use them).
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).
Adds a TrimWhiteSpace instead of using abseil's.
Adds Catch2 tests for it, and also converts the existing str tests to
catch (which look much, much nicer than the gtest ones).
The comparison done here was really weird: by comparing lengths *before*
contents "zz" would sort before "aaa". It wasn't invalid for the
specific purpose being used here (looking for true/false values), but
would be highly broken if someone tried to use it elsewhere.
Also renamed it because it really is just a `<` implementation, not a
full cmp implementation.
These aren't needed: CMake already knows how to follow #includes and
rebuild when headers change as long as the headers are included
*somewhere*. The extra .cpp files here just require building a bunch of
.cpp files with just header content that we just end up throw away
during linking (since the same things will also be compiled in whatever
other compilation units include the same headers).
- util::Mutex is now a std::shared_timed_mutex, which is capable of
exclusive and shared locks.
- util::Lock is still present as a std::lock_guard<util::Mutex>.
- the locking annotations are preserved, but updated to the latest
supported by clang rather than using abseil's older/deprecated ones.
- ACQUIRE_LOCK macro is gone since we don't pass mutexes by pointer into
locks anymore (WTF abseil).
- ReleasableLock is gone. Instead there are now some llarp::util helper
methods to obtain unique and/or shared locks:
- `auto lock = util::unique_lock(mutex);` gets an RAII-but-also
unlockable object (std::unique_lock<T>, with T inferred from
`mutex`).
- `auto lock = util::shared_lock(mutex);` gets an RAII shared (i.e.
"reader") lock of the mutex.
- `auto lock = util::unique_locks(mutex1, mutex2, mutex3);` can be
used to atomically lock multiple mutexes at once (returning a
tuple of the locks).
This are templated on the mutex which makes them a bit more flexible
than using a concrete type: they can be used for any type of lockable
mutex, not only util::Mutex. (Some of the code here uses them for
getting locks around a std::mutex). Until C++17, using the RAII types
is painfully verbose:
```C++
// pre-C++17 - needing to figure out the mutex type here is annoying:
std::unique_lock<util::Mutex> lock(mutex);
// pre-C++17 and even more verbose (but at least the type isn't needed):
std::unique_lock<decltype(mutex)> lock(mutex);
// our compromise:
auto lock = util::unique_lock(mutex);
// C++17:
std::unique_lock lock(mutex);
```
All of these functions will also warn (under gcc or clang) if you
discard the return value. You can also do fancy things like
`auto l = util::unique_lock(mutex, std::adopt_lock)` (which lets a
lock take over an already-locked mutex).
- metrics code is gone, which also removes a big pile of code that was
only used by metrics:
- llarp::util::Scheduler
- llarp:🧵:TimerQueue
- llarp::util::Stopwatch
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").
It seems `__BYTE_ORDER`/`__LITTLE_ENDIAN`/`__BIG_ENDIAN` aren't defined
on macOS, so `if __BYTE_ORDER == __BIG_ENDIAN` was true which made macOS
take the big endian path *twice* (which cancelled out the big endian
conversion).
This makes util/endian.hpp define __LITTLE_ENDIAN__ or __BIG_ENDIAN__
everywhere, and errors if it can't be set.
