- includes are now sorted in consistent, logical order; first step in an attempt to fix the tomfoolery (no relation to Tom) brought in by include-what-you-use
- shuffled around some cmake linking to simplify dependency graph
- superfluous files removed
- routing messages and surrounding code
- shim code in place for iteration and optimization after deciding what to do with buffer, string handling, and subsequent function calls
Lots and lots of places in the code had broken < operators because they
are returning something like:
foo < other.foo or bar < other.bar;
but this breaks both the strict weak ordering requirements that are
required for the "Compare" requirement for things like
std::map/set/priority_queue.
For example:
a = {.foo=1, .bar=3}
b = {.foo=3, .bar=1}
does not have an ordering over a and b (both `a < b` and `b < a` are
satisfied at the same time).
This needs to be instead something like:
foo < other.foo or (foo == other.foo and bar < other.bar)
but that's a bit clunkier, and it is easier to use std::tie for tuple's
built-in < comparison which does the right thing:
std::tie(foo, bar) < std::tie(other.foo, other.bar)
(Initially I noticed this in SockAddr/sockaddr_in6, but upon further
investigation this extends to the major of multi-field `operator<`'s.)
This fixes it by using std::tie (or something similar) everywhere we are
doing multi-field inequalities.
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).
All #ifndef guards on headers have been removed, I think,
in favor of #pragma once
Headers are now included as `#include "filename"` if the included file
resides in the same directory as the file including it, or any
subdirectory therein. Otherwise they are included as
`#include <project/top/dir/relative/path/filename>`
The above does not include system/os headers.
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.
Git blame's --ignore-rev flag can be used to ignore this commit when
attempting to `git blame` some code.
