This is more of a question, as I couldn't find it in the documentation. Does aria2 do any checks when downloading a file from multiple sources to ensure all of them are actually referencing the same file? Some basic checks might be based on comparing: 1) file size, 2) date (might not be consistent or even available), 3) first and last few bytes, 4) small chunk overlap, and compare the small ove

Request

This issue is for capturing actions arising from @horenmar 's request on Discord of 2019-06-15 "Help wanted: documentation"

The current documentation is pretty okay, but it definitely shows that it has evolved over multiple years, using different expository styles and was targeted at different audience.

And as the feature set grows, the documentation needs to become more

The doc is great! Hoewever some areas are still missing.
C++11 intoduced raw string literals: https://en.cppreference.com/w/cpp/language/string_literal

It is useful in many different areas, like strings with quotes, multiline strings and for example windows paths without escaping backslashes:

const char win_path[] = R"(c:\some\unescaped\path)";

The same cppreference link als

The links on the FAQ page in the wiki still point to the old wiki, which seems to be deprecated.

Minetest version

0.4.17.1

Summary

The keybindings menu has that weird warning at the top:

(If this menu screws up, remove stuff from minetest.conf)

Is this warning still relevant? I think this warning has been in Minetest since ages, yet it's still there.

If the warning is still relevant, please write down (in this

There are some issues of code quality. Like createPoller() returns a pointer to a poller which locates heap.

And we should fix these issues. If you think there are code quality issues, please comment in this issue. Thanks a lot.

doctest currently has an option not to print the version, so that printVersion() starts with:

         void printVersion() {
             if(opt.no_version == false)

I suggest that the same option be added for the intro text, i.e.

        void printIntro() {
+            if(opt.no_intro == false) {
             printVersion();
             // etc. etc.
+            }

收到解析回调后，执行了下面的代码
truct sockaddr_in saddr;
memset(&saddr, 0, sizeof(saddr));
saddr.sin_addr = addr;
LOG_INFO << "DNS resolved " << host << " ip " << evpp::sock::ToIP(evpp::sock::sockaddr_cast(&saddr));

但是ToIP函数需要知道family，这里显然没有传入这个值，导致一直输出：
unknown socket family connected

Not really a priority, but this is going to happen as number grows beyond 8192 😢, since current implementation uses std::setw(4) when prining each tile.

GCC appears to evaluate transform function calls out of order, which I think it's allowed to do because function argument evaluation order is undefined. Hana should explicitly document the lack of ordering guarantees in transform.

As for Display the special operations generated by the compiler #224 discussion, the documentation will improve if we had a section describing the transformation of each featre and his limitations.

In particular for the special operation, to explain that only the operations that are really generated would appear in the transformation. This is due to the fact that the tool s based on the AST.

I was trying the support for custom converters described in https://cliutils.gitlab.io/CLI11Tutorial/chapters/advanced-topics.html#custom-converters

I was curious about the constraint to set up the custom istringstream& operator << overload before including CLI11.

Could you provide any pointers as to what's the concrete C++ limitation that doesn't allow us to be more flexible in this sense

We'd appreciate a PR to add CI tests for MinGW. Ideally, we are looking for a maintainer that also takes care of maintenance of those jobs and MinGW support in general.

It would be a cool proof of concept to see Flecs running in the browser. As a first step towards this, the ecs_graphics project could be ported as it showcases the bare minimum for a game with graphics (input + rendering).

Hi All,

I want to write a config file for my client. I just need to encode the options:

./ssf -U 53:127.0.0.1:53 -p 443 ..81.45

In the appropriate config file, but I don't understand how to do. I just understood that because this is the client I just need datagram_listener and not datagram_forwarder, but how can I specify the local port, the remote port, and the IP where to bind it?

the correct result of the example in Vc::iif should be [2,1,1,5] (if i understood it correctly)
and I am not sure whether the code example in Vc::simd_for_each is correct, therefore I did not make a PR.

void scale(std::vector<double> &data, double factor) {
  Vc::simd_for_each(data.begin(), data.end(), [&](auto v) {
     v *= factor;
  });
}

If one gets v by value, it chang
