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
Get rid of the --win32-daemon hack (which was removed from the service
itself earlier in this PR, by mistake) and replace it with detection of
the error code for "not running as a service" that windows gives us back
if we try to set up service controller dispatching but aren't a service.
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 should send STOP_PENDING rather than STOPPED while we aren't yet
actually stopped; STOPPED is already sent when we actually finish
stopping.
Also fixes some silly argc/argv shenanigans, I think.
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).
Currently you can't use GUI_EXE without BUILD_GUI, but BUILD_GUI also
requires the yarn command (even though it will never use it when GUI_EXE
is set).
This commit fixes it:
- Make `GUI_EXE` a windows-only top-level project options, rather than
being guarded by `BUILD_GUI`.
- Make `BUILD_GUI` control *building* the GUI instead of bundling it.
- GUI_EXE and BUILD_GUI are now mutually exclusive.
The options we need in rsvg-convert are apparently too new for bullseye,
so split the build so that we do the gui separately (in the nodejs-lts
container) and then build lokinet in bookworm.
