New features

• xrepo

xrepo install -f "openssl=true,libcurl=true" co

• vcpkg

vcpkg install co:x64-windows

# http & ssl support
vcpkg install co[libcurl,openssl]:x64-windows

• defer (similar to defer in golang)

#include "co/defer.h"
Timer t;
defer(LOG << "time elapse: " << t.us() << "us");

• channel for coroutine (similar to channel in golang)

#include "co/co.h"

DEF_main(argc, argv) {
    co::Chan<int> ch;
    go([ch]() {
        ch << 7;
    });

    int v = 0;
    ch >> v;
    LOG << "v: "<< v;

    return 0;
}

• waitgroup (similar to sync.WaitGroup in golang)

#include "co/co.h"

DEF_main(argc, argv) {
    FLG_cout = true;

    co::WaitGroup wg;
    wg.add(8);

    for (int i = 0; i <8; ++i) {
        go([wg]() {
            LOG << "co: "<< co::coroutine_id();
            wg.done();
        });
    }

    wg.wait();
    return 0;
}

• Coroutine hook for windows.

• Create coroutines in specified scheduler(thread).

auto s = co::next_scheduler();
s->go(f1);
s->go(f2);

• Create coroutine in all schedulers.

auto& s = co::all_schedulers();
for (size_t i = 0; i <s.size(); ++i) {
    s[i]->go(f);
}

• Add void flag::init(const fastring& path);

Changed

• Closure to co::Closure.

• Improve co::Event, can be used anywhere, and support copy constructor and capture by value in lambda.

• Improve co::Mutex, co::Pool, support copy constructor and capture by value in lambda.

• co::close() now can be called anywhere, not necessary to call it in the thread that performed the IO operations.

• Partial support for mingw. Coroutine and coroutine-based features do not work for mingw at present.

Bugs fixed

• fix bug in fs::file when read/write more than 4G bytes.

• fix connect timeout error for http::Client.

• fix link problem in #165.
