Get a SIGPIPE error using indy...

[sinfoni]

Hi all,

Lazarus 0.9.29, FPC 2.4.0, Indy 10.2.0.3.

I get a SIGPIPE and application crash with this code. Sometimes during the first call, often the second call... However, the request works : I receive the email confirmation created by the web server.

Code: [Select]

try
    ms:=TMemoryStream.Create;         
    Form1.IdHttp1.Get(gc_www, ms); // SIGPIPE !!!
    If ms.Size <> 0 Then Begin
          etc...
 
Any idea ?

Thanks,
André.

It's probably related to this: http://bugs.freepascal.org/view.php?id=9401

The Indy authors probably "fixed" the problem by commenting out the use of MSG_NOSIGNAL on Mac OS X, without adding SO_NOSIGPIPE when creating the sockets.

And... How can I solve the issue ?
I've tried to put MSG_NOSIGNAL in unxsockh.inc without success.
I've tried to replace

Code: [Select]

Result := CheckForSocketError(fpsend(ASocket, @ABuffer, ABufferLength, AFlags));by

Code: [Select]

Result := CheckForSocketError(fpsend(ASocket, @ABuffer, ABufferLength, AFlags or Id_MSG_NOSIGNAL));in IdStackUnix.pas without success...

I have found some post about this subject but non solution...

I don't know, I've never used Indy. You should probably file a bug report with the Indy developers about this.

Please read the comments to the bug report again, especially the last comment by me. MSG_NOSIGNAL is not a flag for fpsend, but for fpconnect.

I can't see any way to pass a flag to fpconnect ...

Code: [Select]

CheckForSocketError(fpConnect(ASocket, @LAddr, SizeOf(LAddr)));

Sorry, it's via fpsetsockopt(). See "man setsocketopt" in a Mac OS X terminal window for info on how to use it.

I'm still lost. I did not develop indy...

Does Indy work or not ? That is the question.

Me neither.

It works, but has bugs just like every other piece of software in existence. As I said: file a bug report with the Indy developers.

[sinfoni]

There is already a bug report about SIGPIPE, and it is marked as resolved...

Is there any other simple way to get a http request without using Indy ?   

[sinfoni]

Well,

I've tried to do a bug report, without success because bug reporting is now closed to public users, nice.

Anyway, I have found a workaround: I have added this code before every call to the get method, and now it works.

Code: [Select]

idHTTP1.Free; IdHTTP1 := TidHTTP.Create;
It seems that Indy does not release all ressources after a call or something like that...

Thanks,
André.

The bugtracker is open for anybody, I just tested it.
