<Papierkorb> do you mean catch/throw as in ruby's sense?
Elias Perez
@eliasjpr
yes
I just wondered if Crystal has that kind of control flow
From IRC (bridge bot)
@FromIRC
<Papierkorb> break etc. - Don't use the exception mechanism for control flow
Elias Perez
@eliasjpr
I hate using exception for my case, and break just exits the current method, when I really want to do is jump to a different flow
maybe that’s a feature request?
From IRC (bridge bot)
@FromIRC
<Papierkorb> That feature is barely needed, and would potentionally be hard to do - Not even speaking of doing it right
<Papierkorb> If "doing it right" is even possible
Elias Perez
@eliasjpr
interesting, I gues the dynamic nature of ruby allow this to be done more easily
Johannes Müller
@straight-shoota
That might be a factor... but I'm not sure if it would be too difficult to add to Crystal . But as I understand it, it is deliberately not a thing because there is no real usecase and it makes things unnecessarily complicated.
Elias Perez
@eliasjpr
@straight-shoota is there any documentation of the lifecycle when an exception is raised?
Johannes Müller
@straight-shoota
sorry, I don't know

@straight-shoota thanks reading

@elorest
has anyone expirienced an issue where context.response.headers don’t all end up in the headers from curl or the browser. Sort of sporatically.

@FromIRC
<bmcginty> Anyone here have issues detecting closed sockets? I'm trying to check to see if a persistent connection is still alive, and I can't figure out when/what is supposed to be returned when the remote end of a socket closes.
<bmcginty> @elorest: I was seeing weird http stuff last week...weird enough that I'm trying to write/use my own to figure out what was going on. Though mine has just been in the client.

<oprypin> @elorest, hopefully you aren't putting broken strings with arbitrary bytes in there?

Good morning everyone
Isaac Sloan
@elorest
Morning.
Isaac Sloan
@elorest
<oprypin> For some reason if the body is even moderately large(~200 elements) it changes to chunked mode and overwrites the existing headers with
< HTTP/1.1 200 OK
< Connection: keep-alive
< Transfer-Encoding: chunked
If I reduce the size of the http body all of my headers get sent.
And my cookies get set in my browser.
From IRC (bridge bot)
@FromIRC
<shelvacu> Is it a consistent size that changes it? Maybe 4k bytes or something?
Isaac Sloan
@elorest
Working one with smaller body.
< HTTP/1.1 200 OK
< Connection: keep-alive
< Set-Cookie: test_session=eyJjc3JmLnRva2VuIjoiSlFMdGVzTXFmUzBwZDlXYmVSSkpMVUtmbGFzME93eEFINkNrRHlXYkNUMCIsIl9mbGFzaCI6IntcImZsYXNoZXNcIjp7fSxcImRpc2NhcmRcIjpbXX0ifQ%3D%3D--OPgRdhc%2BbD0AQp1Xz88kvrQ%2Fwj4%3D; path=/; HttpOnly
< Content-Length: 6680
Same url.
I’ll try to find the content lenght where it breaks.
From IRC (bridge bot)
@FromIRC
<shelvacu> Do you have some code that reliably reproduces it?
Isaac Sloan
@elorest
Yes.
From IRC (bridge bot)
@FromIRC
<shelvacu> You should definitely file a bug report.
<shelvacu> Or post the code here so I can file such a report
Isaac Sloan
@elorest
Content-Length: 8191 works but one more character in the body and it goes to chunked and doesn’t send headers.
From IRC (bridge bot)
@FromIRC
<shelvacu> https://github.com/crystal-lang/crystal/blob/f026c474450176ff1b86293bf0abc6afdc497137/src/http/common.cr#L157 seems the most likely culprit but I don't see how that would cause any problems.
<shelvacu> deflate compression lib and stdlib buffered io both use a buffer size of 8192
<shelvacu> 1
Isaac Sloan
@elorest
Yeah I’m finding stuff about that number everywhere. As far as html pages are concerned it’s not really that big.
I believe that chunking after that size is appropriate. I just tested a couple rails sites. They also chuck after 8191 but they don’t delete my headers in the process.

<bmcginty> @oprypin: It's with sockets that I'm having the issue. Straight reading from them times out (while checking to see if .read returns 0).
Bar Hofesh
@bararchy
bmcginty: Can you share a code exmaple ?
From IRC (bridge bot)
@FromIRC
<oprypin> bmcginty, no difference
<oprypin> sockets when explicitly closed will get you 0. but detecting remote socket going away is not reliable, hence timeout
From IRC (bridge bot)
@FromIRC
<bmcginty> @oprypin: thanks.

Hi, everyone... I'm stuck using concurrency for a simple logger...

I have a Process, a spawn where the output is print and i want to use another spawn where each 3 seconds for example, kill the old Process and send the new one to the first spawn, I was trying with channels but the spawn must wait for a send.

In little words, is there a way to create just a "listener"between spawns without wait for it?

Bar Hofesh
@bararchy
Buffered Channel maybe ?
Cris Ward
@crisward
Can anyone explain to me what this does
Signal::PIPE.trap do
  # some code
end
Akzhan Abdulin
@akzhan
This is signal handler. They interrupts process execution for some events.
