<mps> perl greedy matches make me ... uff

<mps> yes, it should close listening socket but not active ones

didactic-drunk

@didactic-drunk

@mps could you test #10884 and see if it fixes your problem?

Francisco Adasme

@franciscoadasme

hey everyone, is there a way to declare a subtype of a typevar (T::U) in a type restriction?, something like this:

struct Foo; end
struct Foo::Bar; end

module A(T)
  abstract def bar : T::Bar
end

class B
  include A(Foo)

  def bar : Foo::Bar
    Foo::Bar.new
  end
end

George Dietrich

@Blacksmoke16

include A(Foo::Bar)

and just use T

@FromIRC

<mps> @didactic-drunk: I have to rebuild crystal for this, iiuc

didactic-drunk

@didactic-drunk

You could possibly use an existing 1.0.0 build

From IRC (bridge bot)

@FromIRC

<mps> I don't keep it around because my arm64 machines are too slow to build crystal

Francisco Adasme

@franciscoadasme

@Blacksmoke16 This was a simplified example, the module includes other methods that work on T, so I cannot simply use Foo::Bar

George Dietrich

@Blacksmoke16

include A(Foo, Foo::Bar)?

<mps> @didactic-drunk: btw, I maintain crystal in last 2 years for alpine linux

<mps> for any change I have to use alpine builders and to push changes to distro

<mps> @didactic-drunk: anyway I will try this patch on my local box on weekend, thank you for it

didactic-drunk

@didactic-drunk

You can probably use an existing compiled 1.0.0 crystal binary with the std lib source from my branch (or just copy http/server.cr)

From IRC (bridge bot)

@FromIRC

<mps> ah, lets see

From IRC (bridge bot)

@FromIRC

<mps> @didactic-drunk: In /usr/lib/crystal/core/http/server.cr:505:9

<mps> 505 | sleep timeout

<mps> Error: no overload matches 'sleep' with type Nil

<mps> but looking into patch, this is some kind of reference counting also?

didactic-drunk

@didactic-drunk

Did you use close with or without a timeout?

From IRC (bridge bot)

@FromIRC

<mps> without timeout, I want to close listening socket imediately

didactic-drunk

@didactic-drunk

Try close timeout: 0

Um. Listening sockets are closed immediately regardless of timeout. Timeout is the wait time for already accepted client connections

From IRC (bridge bot)

@FromIRC

<mps> yes, patch didn't helped

didactic-drunk

@didactic-drunk

Try timeout: 80

From IRC (bridge bot)

@FromIRC

<mps> will this close listening socket imediately?

<mps> even with 'timeout: 80' doesn't work

didactic-drunk

@didactic-drunk

It should

From IRC (bridge bot)

@FromIRC

<mps> dies immediately

didactic-drunk

@didactic-drunk

Do you have a client connection open before ctrl+c?

From IRC (bridge bot)

@FromIRC

<mps> yes

didactic-drunk

@didactic-drunk

Works on my end

With your test code

From IRC (bridge bot)

@FromIRC

<mps> hm

<mps> ok, thanks

Francisco Adasme

@franciscoadasme

@Blacksmoke16 ok, thanks

From IRC (bridge bot)

@FromIRC

<mps> I will try to build crystal with your patch on weekend and test again

didactic-drunk

@didactic-drunk

Can you test on non-arm?

From IRC (bridge bot)

@FromIRC

<mps> I can, but maybe next week (ditched x86 few years ago)

<mps> hmm, maybe I can 'usurp' my alpine developers lxc

<mps> but not now, it is to busy by building a lot of pkgs now

didactic-drunk

@didactic-drunk

Nm. It's possible it needs crystal master although I don't see why. I hope it's not an arm thing

From IRC (bridge bot)

@FromIRC

<mps> last time I tried it was same on arm and x86

@FromIRC

<postmodern> is there a way to create an tuple of arbitrary length, but all elements are of the same type?

George Dietrich

@Blacksmoke16

No tuples are fixed suze by design

Size

Chris Watson

@watzon

Is there a good thread safe queue yet?

Or am I going to have to implement one quickly?

George Dietrich

@Blacksmoke16

Rabbit?
