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.
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.
* wintun vpn platform for windows
* bundle config snippets into nsis installer for exit node, keyfile persisting, reduced hops mode.
* use wintun for vpn platform
* isolate all windows platform specific code into their own compilation units and libraries
* split up internal libraries into more specific components
* rename liblokinet.a target to liblokinet-amalgum.a to elimiate ambiguity with liblokinet.so
* DNS platform for win32
* rename llarp/ev/ev_libuv.{c,h}pp to llarp/ev/libuv.{c,h}pp as the old name was idiotic
* split up net platform into win32 and posix specific compilation units
* rename lokinet_init.c to easter_eggs.cpp as that is what they are for and it does not need to be a c compilation target
* add cmake option STRIP_SYMBOLS for seperating out debug symbols for windows builds
* intercept dns traffic on all interfaces on windows using windivert and feed it into lokinet
* make socket bind errors have a distinct message reported when caught using their own exception type
* omit printing banner in setup when we run from the lokinet executable (but not the liblokinet.so entry point)
Replaces custom logging system with spdlog-based oxen logging. This
commit mainly replaces the backend logging with the spdlog-based system,
but doesn't (yet) convert all the existing LogWarn, etc. to use the new
format-based logging.
New logging statements will look like:
llarp::log::warning(cat, "blah: {}", val);
where `cat` should be set up in each .cpp or cluster of .cpp files, as
described in the oxen-logging README.
As part of spdlog we get fmt, which gives us nice format strings, where
are applied generously in this commit.
Making types printable now requires two steps:
- add a ToString() method
- add this specialization:
template <>
constexpr inline bool llarp::IsToStringFormattable<llarp::Whatever> = true;
This will then allow the type to be printed as a "{}" value in a
fmt::format string. This is applied to all our printable types here,
and all of the `operator<<` are removed.
This commit also:
- replaces various uses of `operator<<` to ToString()
- replaces various uses of std::stringstream with either fmt::format or
plain std::string
- Rename some to_string and toString() methods to ToString() for
consistency (and to work with fmt)
- Replace `stringify(...)` and `make_exception` usage with fmt::format
(and remove stringify/make_exception from util/str.hpp).
* use std::source_location instead of godawful macros in logging
* remove unused/absolutely haram af json logstream
* fix bug in android logger where it doesn't respect eLogNone
We were linking/loading it in different ways, one with cmake option
`USE_JELLOC` and the other, older version `WITH_JEMALLOC`. This removes
the latter (which was default OFF) and keeps the former (which was added
and has been default ON since 0.9.4 or so).
Also removes the `ifdef`ed JEMALLOC code in lokinet.cpp because we don't
need it; just linking to jemalloc is enough to get the malloc/free
replacements.
