- Add libuv submodule (only needed and built on Windows)
- Temporarily switch uWebSockets to my github repo: I submitted some
mingw compilation fixes upstream; as soon as a new upstream release
comes out we will switch this back to the upstream repo.
- Switch BOOST_SCOPE_EXIT to LOKI_DEFER
- Don't compile `closefrom()` on Windows (it isn't used, and generates
an unused function warning).
Because:
boost::join(v | boost::adaptors::transformed([](uint64_t out){return std::to_string(out);}), " ")
is ugly as sin, while:
tools::join(" ", v)
is nice and simple.
Also removes a few unnecessary boost iterator adaptor includes and uses.
common/util.h has become something of a dumping ground of random
functions. This splits them up a little by moving the filesystem bits
to common/file.h, the sha256sum functions to common/sha256sum.h, and the
(singleton) signal handler to common/signal_handler.h.
NetBSD emits:
warning: Warning: reference to the libc supplied alloca(3); this most likely will not work. Please use the compiler provided version of alloca(3), by supplying the appropriate compiler flags (e.g. not -std=c89).
and man 3 alloca says:
Normally, gcc(1) translates calls to alloca() with inlined code. This is not done when either the -ansi, -std=c89, -std=c99, or the
-std=c11 option is given and the header <alloca.h> is not included. Otherwise, (without an -ansi or -std=c* option) the glibc version of
<stdlib.h> includes <alloca.h> and that contains the lines:
#ifdef __GNUC__
#define alloca(size) __builtin_alloca (size)
#endif
It looks like alloca is a bad idea in modern C/C++, so we use
VLAs for C and std::vector for C++.
