Default & Required makes no sense: if we have a default it makes no
sense to make it required. The previous behaviour when this was
specified was to force an (uncommented) value in the config with the
value, but this was only used in the test suite.
Required & Hidden makes no sense either: if it's required to be
specified we definitely don't want to hide it from the generated config
file.
These are now compile-time failures.
When running as a service node we can't do anything without a lokid rpc
URL, and we don't necessarily have a good default for it.
This makes it required so that we fail with an appropriate error message
(rather than connect timeouts) if it is not specified.
At some point between 0.9.9 and 0.9.10 we removed the printing of option
names when a value doesn't have a default, but this means the config is
littered with things like:
# This option sets the greater foo value.
with no actual option name printed out when there is no default.
This fixes it by always printing the option name in such a case, just
with an empty value, e.g.:
# This option sets the greater foo value.
#big-foo=
certain files needed to include either fstream and our shim for std::filesystem.
this includes fstream into our shim and includes this shim in places
that require fstream. this is done because some toolchains (cough
cough broke af arch linux amalgums) can have weird subsets of the
requirements of C++17 that overlap, except when they dont, denoted by
unknowable undisclosed circumstances.
this issue was reported by a user in the wild, and this fixes it.
previously we had a checking style function that passes in an optional
defaulting to nullopt as a micro optimzation, this makes the code
unnessarily obtuse.
simplify this by splitting up into 2 functions,
one for getting the unique endpoints and one for checking if the
number of them is above the minimum.
add overload for ReadyToDoLookup() that checks against constant but
can do more in the future if desired to reduce the burden on future contributors.
Query->Cancel() will remove the Query, but that introduces a race
condition where unbound may still try to invoke the callback (with a
no-longer-valid pointer) if we do it before the ub_ctx_delete call.
Move to it afterwards so that we only cancel things that unbound didn't
Occasionally during shutdown windivert will crash because a thread tries
sending after we've called wd::shutdown, which isn't allowed. Add an
atomic bool to prevent this.
we were calling llarp::Context::HandleSignal from a non mainloop
thread when running as a win32 service. this caused issues with a non
clean destruction.
call our signal handler instead of llarp::Context::HandleSignal
If wintun fails it seems to take about 15s, so extend the startup
timeout so that it can fail gracefully (and let us clean up before
exiting).
Also refactors the timeouts to chrono constants.
Fixes windows shutdown crashes:
- windivert wasn't handling an ERROR_NO_DATA, which it gets when
finished handling everything after a shutdown.
- wintun ReadPacket still gets invoked after end_session is called, but
shouldn't be. This adds an atomic<bool> to early return.
- fixes up some settings we send for windows service manager notify
- win32_platform.cpp is dead
- win32_platform.hpp is useless
Style changes from clang-tidy warnings:
- remove `virtual` from some definitions that already have `override`
- remove virtual destructor from NetworkInterface because it already has
a virtual destructor via the base type (and clang-tiny warns about it)
the win32 and sd_notify components provided a disjointed set of
similar high level functionality so we consolidate these duplicate
code paths into one that has the same lifecycle regardless of platform
to reduce complexity of this feature.
this new component is responsible for reporting state changes to the
system layer and optionally propagating state change to lokinet
requested by the system layer (used by windows service).
We're defining formats for std::chrono types, which feels wrong (because
fmt itself also has these), so just replace them with functions:
short_time_from_now(...) gives a short "in 14m12s" or "5.123s ago" time
span relative to now, given a time point. Precision gets reduced for
larger deviations from now (e.g. "4h12m ago").
ToString(Duration_t) gives a string such as "-3h22m02.123s" for a
duration.
The time_delta<T> was using the wrong duration type when formatting, so
was outputting millisecond precision in the systemd status string which
is pointless (and unintended).
The iterator here to skip an obsolete bootstrap wasn't properly
reassigning the iterator, so "didn't work" (though why it was hanging
for me is entirely non-obvious).
Also refactored it to simplify/clarify it a bit.
- Move logging initialization to early in Configure rather than at the
end of FromConfig so that we can add debug logging inside
Configure/FromConfig/etc.
- add said debug logging to Configure/FromConfig/etc.
Without this, old config (with now-irrelevant settings) won't work in
newer lokinet, making lokinet fatal error on startup if one of the
no-longer-used options is still present.
