However, i'm having a little trouble understanding one crucial part of the specification. I may be lacking some fundamental knowledge here, so, please bear with me! I need to create a socket in my webserver application before launching the fastCGI app. So, I do this, and I have the socket handle. The specification reads "The Web server leaves a single file descriptor, FCGI_LISTENSOCK_FILENO, open when the application begins execution. This descriptor refers to a listening socket created by the Web server." How does the FastCGI application get my socket handle? I see from the spec that FCGI_LISTENSOCK_FILENO is a constant of 0. And a file descriptor of 0 refers to STDIN, does it not? Is this a roundabout way of saying that I need to use STDIN to communicate? I'd appreciate any help you guys can give.

After adding a retry functionality, we noticed no more of these errors and the responses were delivered with the correct content. So I attach the patch we used. Some comments: There are two situations, that are handled by the patch: A) After select() in socket_io() indicates, that the response can be read, but the following readv() in fcgi_buf_socket_recv() returns with EAGAIN. Normally this should not happen, but it isn't forbidden and at least on AIX 5.2 we noticed exactly this behaviour. It only showed up sporadically, but when it happens, because mod_fastcgi aborts the request we get status codes 500. B) select() in socket_io() can return with EINTR. We implemented a retry loop, which sleep 1 second and loops max 10 times in order to prevent a non terminating loop. We also noticed this behaviour on AIX 5.2 under stress (sporadically). The loop never ran more than twice. The one second sleep might not be ideal, but since the problem only happens very rarely, it looked safer, than a shorter sleep. Thanks for producing mod_fastcgi!

If the webserver forks the application, it leaves FD0, and STDERR, STDIN, and STDOUT are mutiplexed over it using the FastCGI protocol.

If it's a socket connect, it's basically the same thing - you'll to an accept(), and when you get the FD, use the libraries to send/receive data on the socked.

Hi all,

I'm currently in the process of expanding my webserver to support FastCGI. However, i'm having a little trouble understanding one crucial part of the specification.

I may be lacking some fundamental knowledge here, so, please bear with me!

I need to create a socket in my webserver application before launching the fastCGI app. So, I do this, and I have the socket handle.

The specification reads "The Web server leaves a single file descriptor, FCGI_LISTENSOCK_FILENO, open when the application begins execution. This descriptor refers to a listening socket created by the Web server."
How does the FastCGI application get my socket handle?  I see from the spec that FCGI_LISTENSOCK_FILENO is a constant of 0.  And a file descriptor of 0 refers to STDIN, does it not? Is this a roundabout way of saying that I need to use STDIN to communicate?

I'd appreciate any help you guys can give.

Many thanks,

Tom

I develop a fastcgi based application but after I made a few requests I have to restart the apache using /etc/init.d/apache2 force-reload to be able to replace the old executable with the old one. Example: $ sudo cp test2.fcgi /usr/lib/cgi-bin/test2.fcgi cp: regular file "/usr/lib/cgi-bin/test2.fcgi": Text file busy $ sudo /etc/init.d/apache2 force-reload $ sleep 2 <-- takes at least two seconds $ sudo cp test2.fcgi /usr/lib/cgi-bin/test2.fcgi <-- now works fine Do you have any solutions how to optimize this? regards Steffen Wendzel From davidb@pins.net Wed Aug 6 10:19:49 2008 Return-Path: Received: from localhost.localdomain (unknown [209.212.65.37]) by spam.chelsea.net (Postfix) with ESMTP id 08D2C1E2F7 for ; Wed, 6 Aug 2008 10:19:48 -0400 (EDT) Received: from real.pins.net (mail.chelsea.net [209.212.66.16]) by smtp.chelsea.net (Postfix) with ESMTP id 60F0E492F for ; Wed, 6 Aug 2008 10:19:38 -0400 (EDT) Received: from spam.chelsea.net ([209.212.65.24] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTP id 273008672 for fastcgi-developers@fastcgi.com; Wed, 06 Aug 2008 10:19:38 -0400 Received: from localhost.localdomain (unknown [209.212.65.42]) by spam.chelsea.net (Postfix) with ESMTP id 4A0981E2F7 for ; Wed, 6 Aug 2008 10:19:48 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.4 (2008-01-01) on abe.chelsea.net X-Spam-Status: No, score=-8.8 required=5.0 tests=ALL_TRUSTED,AWL,BAYES_00, DOC_MAIL_LIST_BODY_DB,GOOGLE_PORN_LONGER autolearn=ham version=3.2.4 X-Spam-Level: Received: from smtp.chelsea.net ([209.212.66.17] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTP id 273008647 for fastcgi-developers@fastcgi.com; Wed, 06 Aug 2008 10:19:34 -0400 Received: from rarevos.pins.net (rarevos.pins.net [209.212.65.43]) by smtp.chelsea.net (Postfix) with ESMTP id 83D344925; Wed, 6 Aug 2008 10:19:34 -0400 (EDT) Date: Wed, 6 Aug 2008 10:20:38 -0400 (EDT) From: David Birnbaum To: Steffen Wendzel In-Reply-To: <20080806101321.cb527bdf.cdp_xe@gmx.net> X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-ID: References: <20080806101321.cb527bdf.cdp_xe@gmx.net> User-Agent: Alpine 1.10 (GSO 962 2008-03-14) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed X-CGP-External-Filter: YES Cc: fastcgi-developers@fastcgi.com Subject: Re: [FASTCGI] apache restart X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 06 Aug 2008 14:19:56 -0000 Steffen, You're trying to overwrite, and the OS has it locked.

A strategy I have used that has worked well is to have the application keep track of the timestamp on its executable file. When the time stamp changes, exit. I do the check before handling each request. It might be better to do it after the request, but that might cause problems being sure you are running the latest version in a compile and test cycle. Then to roll out a new version I do: mv prog prog.old; mv prog.new prog The first method has the advantage of being able to undo the change if it goes horribly wrong. This works as well: rm prog; mv prog.new prog This works because Linux maintains a link to the file as long as it is executing. The disk space is not recovered until exit. This also works beautifully in a gcc compile and test cycle because gcc removes the old one before creating the new one. -- Bryan White From webmaster@cosmicperl.com Thu Aug 7 12:18:19 2008 Return-Path: Received: from localhost.localdomain (spam.chelsea.net [209.212.65.13]) by spam.chelsea.net (Postfix) with ESMTP id 7B32B6D7FE for ; Thu, 7 Aug 2008 12:18:19 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.4 (2008-01-01) on strohs.chelsea.net X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00, DOC_MAIL_LIST_BODY_DB, GOOGLE_PORN_LONGER, PINS_GAMBLE_BODY autolearn=ham version=3.2.4 X-Spam-Level: Received: from ns.cosmicsitehosting.com (ns.cosmicsitehosting.com [213.133.65.182]) by smtp.chelsea.net (Postfix) with ESMTP id 55EEB42BA for ; Thu, 7 Aug 2008 12:17:58 -0400 (EDT) Received: from [192.168.1.10] (78-86-207-240.zone4.bethere.co.uk [78.86.207.240] (may be forged)) (authenticated bits=0) by ns.cosmicsitehosting.com (8.13.4/8.13.4) with ESMTP id m77G5kvM017648; Thu, 7 Aug 2008 17:05:51 +0100 X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-ID: <489B2034.4080503@cosmicperl.com> Date: Thu, 07 Aug 2008 17:17:56 +0100 From: Lyle User-Agent: Thunderbird 2.0.0.16 (Windows/20080708) MIME-Version: 1.0 To: David Birnbaum References: In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Cc: fastcgi-developers@mailman.pins.net Subject: Re: [FASTCGI] List Repair X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 07 Aug 2008 16:18:25 -0000 David Birnbaum wrote: > Folks, > > The FastCGI lists have been down for a while due to a mail problem.

Hi David, Thought I hadn't had any FastCGI emails for a while... By the way I've been held up the last 6 months on a big software project that has taken up all of my time. I'm finally getting to the stage where I'm incorporating FastCGI on Linux/Apache Linux/Lighttpd Windows/IIS Windows/Apache Windows/Lighttpd I'll be working through and writing guides for each on setting up the server with FastCGI then writing scripts in Perl that'll work across all of them. Wish me luck :) Lyle From davidb@pins.net Fri Aug 8 14:55:57 2008 Return-Path: Received: from localhost.localdomain (unknown [209.212.65.16]) by spam.chelsea.net (Postfix) with ESMTP id B30C96D824 for ; Fri, 8 Aug 2008 14:55:57 -0400 (EDT) Received: from real.pins.net (mail.chelsea.net [209.212.66.16]) by smtp.chelsea.net (Postfix) with ESMTP id C1A5548E2 for ; Fri, 8 Aug 2008 14:55:44 -0400 (EDT) Received: from spam.chelsea.net ([209.212.65.24] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTP id 273293884 for fastcgi-developers@fastcgi.com; Fri, 08 Aug 2008 14:55:46 -0400 Received: from localhost.localdomain (unknown [209.212.65.33]) by spam.chelsea.net (Postfix) with ESMTP id AA3BA1E2AE for ; Fri, 8 Aug 2008 14:55:56 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.4 (2008-01-01) on abita.chelsea.net X-Spam-Status: No, score=-8.7 required=5.0 tests=ALL_TRUSTED,AWL,BAYES_00, DOC_MAIL_LIST_BODY_DB, FOUND_OTB, PINS_GAMBLE_BODY autolearn=ham version=3.2.4 X-Spam-Level: Received: from smtp.chelsea.net ([209.212.66.17] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTP id 273293749 for fastcgi-developers@fastcgi.com; Fri, 08 Aug 2008 14:55:44 -0400 Received: from rarevos.pins.net (rarevos.pins.net [209.212.65.43]) by smtp.chelsea.net (Postfix) with ESMTP id 084EB48BA; Fri, 8 Aug 2008 14:55:42 -0400 (EDT) Date: Fri, 8 Aug 2008 14:56:50 -0400 (EDT) From: David Birnbaum To: Rainer Jung In-Reply-To: <4898D7FB.4030007@kippdata.de> X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-ID: References: <4898D689.10803@kippdata.de> <4898D7FB.4030007@kippdata.de> User-Agent: Alpine 1.10 (GSO 962 2008-03-14) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed X-CGP-External-Filter: YES Cc: fastcgi-developers@fastcgi.com Subject: Re: [FASTCGI] [Patch] Improve handling of interrupted system calls X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 08 Aug 2008 18:56:06 -0000 I sent a note off to Rob...I'll see if he can bless this one and take a look at the other open patches that are out there.

Hi David,
 Thought I hadn't had any FastCGI emails for a while...

By the way I've been held up the last 6 months on a big software project that has taken up all of my time. I'm finally getting to the stage where I'm incorporating FastCGI on Linux/Apache
Linux/Lighttpd
Windows/IIS
Windows/Apache
Windows/Lighttpd


I'll be working through and writing guides for each on setting up the server with FastCGI then writing scripts in Perl that'll work across all of them.

Wish me luck :)


Lyle

Hello Saikat,


Tuesday, August 19, 2008, 1:00:53 AM, you wrote:

 The issue you described is related to either FastCGI load balancer or your Apache2 thread manager.

 I would go to worker.c first. By default the worker.c (on windows that is the only supported model) is set up to work 

 on a very powerless machine therefore the ServerLimit as well as MaxClients and MaxRequestsPerChild is configured to consume 

 less memory and CPU (about 3-5% of available modern servers). I wouldn't go into details describing how that affects your Fast CGI servers, 

 just remember - when you start performance test (max server load test) your Apache configuration should allow it to consume almost all server 

 resources. By default you're utilizing only 5% of your server, all the threads are consumed and you got incomplete header error while your

 server load is only 5%. Change parameters in worker.c according to the resources available. Likely that config will be checked by a teenager first by sending 

 the server a numerous requests and seeing how it affects the server's ability to respond. Actually any server could be DOSed, but that is the whole another story.

   

Note that this code only displays the Incomplete headers error during load testing, whats worse is that when the environment for load testing is slightly different (meaning using less virtual machines per host) we dont see this error anymore.


 That might happen because the less hosts you have the more threads are available. It's all in the worker.c. I recommend you to study how Apache2 is

 utilizing available resources before running performance tests. Of course Apache has a built in load restrictions otherwise you would end up with a DOSed host that

 you cannot access even via console.

Hello Folks:

I have written a fascgi client using c++ and the fcgiapp module.  I am using Apache 2.0.63 as my webserver and Windows Server 2003 Web Edition as my operating system. Our load testing environment consists of Linux Hosts running Windows Server 2003 Virtual Machines with this fastcgi c++ client.   Unfortunately I had to use windows due to the fact that one of the libraries was only available on windows.  Anyways during the last set of load tests I see the following error intermittently in the Apache logs:


Incomplete headers (0 bytes) received from server followed by my servername (i.e. the fastcgi client).


I have searched the web and did not see any solutions to this problem except for implementing my own signal handler which I don't really wish to do:


I am attaching parts of the code here for reference:



int main(int argc, char*const argv[] )

{


    try

    {


        //create an input output and an error stream

        //listen on a socket with an appropriate backlog

        //exit if the socket is unable to be opened

        //if the request currently needs to be initialized exit

        std::string port=":9000";

        std::string listenQueueBacklog=400;

        FCGX_Stream *in, *out, *err;

        FCGX_ParamArray envp;

        if (FCGX_Init())

            exit(1);

        int listen_socket = FCGX_OpenSocket(port.c_str(), atoi(listenQueBacklog.c_str()));

        if (listen_socket < 0) exit(1);

        FCGX_Request request;

        if (FCGX_InitRequest(&request, listen_socket, 0)) exit(1);

    


        while (FCGX_Accept(&in, &out, &err, &envp) >= 0)

        {



            //print out the content type and retrieve the query string

            //which is everything after the question mark in the URL

            FCGX_FPrintF(out,"Content-type: text/html\r\nStatus: 200 OK\r\n\r\n");



            //main part of the code goes here

            ..........




        } //end while (FCGX_Accept(&in, &out, &err, &envp) >= 0)

    }//end try block

    catch (std::exception& ex)

    {

    }

    

    return 0;

}





Note that this code only displays the Incomplete headers error during load testing, whats worse is that when the environment for load testing is slightly different (meaning using less virtual machines per host) we dont see this error anymore.



I would really appreciate some help with this issue.

Thanks Again

I'm not sure if it's a bug or I'm using the code incorrectly. Any suggestions would be appreciated. Here's the setup: Apache 2.x (latest version, running on windows xp) is configured to start a single instance of my fastcgi application and communicate over a tcp connection. I picked a random port in the 9000 range. The application starts and I can trace it to the point in the fcgx initialization where it checks stdin/stdout/stderr (function os_libinit() ). The comments say "Determine if this library is being used to listen for FastCGI connections. This is communicated by STDIN containing a valid handle to a listener object". From the web server logs the fastcgi dll is loading my application but tt this point all of the streams return as valid. Here's the code from os_libinit(): if((GetStdHandle(STD_OUTPUT_HANDLE) == INVALID_HANDLE_VALUE) && (GetStdHandle(STD_ERROR_HANDLE) == INVALID_HANDLE_VALUE) && (GetStdHandle(STD_INPUT_HANDLE) != INVALID_HANDLE_VALUE) ) Is this a bug in the fastcgi dll/Apache or am I using it wrong? The next bit of code in the same function checks for an array passed by the initialization call. /* * If there are no stdioFds passed in, we're done. */ if(stdioFds == NULL) { libInitialized = 1; return 0; } Since it always passes null the return is executed. The initialization never calls accept() and never sets the listenType variable. The later calls to fcgx_accept() crash trying to read from the uninitialized web server ipc connection. Also, I plan to modify the library to time out on accept calls instead of blocking forever. I'd like for my fastcgi application to be able to perform maintenance tasks. I planned on detecting the accept() timeout and using that as a reasonable indication the system isn't busy and doesn't have any pending requests to process. I planned on using select() to determine if there were pending requests. Is there any interest in this code? I'd be happy to donate it to the project.

You will need to change mod_fastcgi and rebuild it for Apache 2.2.9 or higher. Starting with Apache 2.2.9, it is necessary to call apr_procattr_io_set() to correctly configure stdin, stdout, and stderr for fastcgi programs before calling apr_procattr_child_in_set(). Here is a patch to fcgi_pm.c which will make mod_fastcgi compatible with Apache 2.2.9+. The patch affects the WIN32 portion of fcgi_pm.c, as this problem is specific to Windows. -tom- --- fcgi_pm.c 2004-04-14 22:01:26.000000000 -0400 +++ fcgi_pm.c 2008-08-26 08:22:15.856008700 -0400 @@ -559,6 +559,10 @@ if (apr_os_file_put(&file, &listen_handle, 0, tp)) goto CLEANUP; + /* required for APR 1.3+ */ + if (apr_procattr_io_set(procattr, APR_FULL_BLOCK, APR_NO_FILE, APR_NO_FILE)) + goto CLEANUP; + /* procattr is opaque so we have to use this - unfortuantely it dups */ if (apr_procattr_child_in_set(procattr, file, NULL)) goto CLEANUP; From whoami@autistici.org Wed Aug 27 10:50:57 2008 Return-Path: Received: from localhost.localdomain (unknown [209.212.65.37]) by spam.chelsea.net (Postfix) with ESMTP id DBAF61E268 for ; Wed, 27 Aug 2008 10:50:57 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.5 (2008-06-10) on strohs.chelsea.net X-Spam-Status: No, score=1.5 required=5.0 tests=AWL,BAYES_50,BOTNET, BOTNET_BADDNS, DOC_MAIL_LIST_BODY_DB shortcircuit=no autolearn=no version=3.2.5 X-Spam-Level: * Received: from confino.investici.org (investici.nine.ch [217.150.252.179]) by smtp.chelsea.net (Postfix) with ESMTP id 58F5159D3 for ; Wed, 27 Aug 2008 10:50:44 -0400 (EDT) Received: by confino.investici.org (Postfix, from userid 33) id D11F6844AE; Wed, 27 Aug 2008 16:50:42 +0200 (CEST) To: fastcgi-developers@mailman.fastcgi.com MIME-Version: 1.0 Date: Wed, 27 Aug 2008 16:50:42 +0200 From: WhoAmI X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-ID: <061a6cee1ec58aa072a0d44ac110ffca@localhost> X-Sender: whoami@autistici.org User-Agent: A/I Webmail (roundcube 0.1rc2) Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 8bit Subject: [FASTCGI] Debian - Php5 - FastCGI Issue X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list Reply-To: whoami@autistici.org List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 27 Aug 2008 14:51:06 -0000 Hello list, I'm using Apache2+FastCGI+Php5 on Debian Etch and i think i've this issue: https://bugs.launchpad.net/debian/+bug/162082 FastCGI + Php5 use up all the available RAM.

I thought I would share with the community. Any fastcgi binary application compiled with Microsoft (msvc 8, etc) compilers and running against a mod_fastcgi compiled under cygwin with a version of 1.5.24 or earlier will fail. The cygwin libraries do not emulate dup2() in such a way that the duplicated handle is reliably inheritable by a child process. This causes the fastcgi application to fail if it uses a tcp/ip connection for interprocess communication. There's a discussion of the problem here: http://www.nabble.com/Socket-inheritance-with-fork-dup2-exec-td11243160.html Jay Sprenkle From eddie@mailforce.net Sat Sep 6 18:50:14 2008 Return-Path: Received: from localhost.localdomain (unknown [209.212.65.42]) by spam.chelsea.net (Postfix) with ESMTP id AFA596D844 for ; Sat, 6 Sep 2008 18:50:14 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.5 (2008-06-10) on abe.chelsea.net X-Spam-Status: No, score=1.0 required=5.0 tests=BAYES_50, BOTNET, BOTNET_BADDNS, BOTNET_SERVERWORDS,GOOGLE_PORN_LONGER shortcircuit=no autolearn=no version=3.2.5 X-Spam-Level: * Received: from out1.smtp.messagingengine.com (out1.smtp.messagingengine.com [66.111.4.25]) by smtp.chelsea.net (Postfix) with ESMTP id 85B525685 for ; Sat, 6 Sep 2008 18:50:08 -0400 (EDT) Received: from compute1.internal (compute1.internal [10.202.2.41]) by out1.messagingengine.com (Postfix) with ESMTP id 0F0DA15D3DA for ; Sat, 6 Sep 2008 18:50:08 -0400 (EDT) Received: from heartbeat1.messagingengine.com ([10.202.2.160]) by compute1.internal (MEProxy); Sat, 06 Sep 2008 18:50:08 -0400 X-Sasl-enc: RHlEju0by+Vj6wiN4RbwsoGqU31uOsx9nqKT2lTAVF6g 1220741407 Received: from [10.0.9.102] (S010600131090f58d.ed.shawcable.net [68.151.53.123]) by mail.messagingengine.com (Postfix) with ESMTPSA id A60421327B for ; Sat, 6 Sep 2008 18:50:07 -0400 (EDT) From: Eddie To: FastCGI Developers List Content-Type: multipart/signed; micalg=pgp-sha1; protocol="application/pgp-signature"; boundary="=-ldSO9QFm8d/6AE/7n5sz" Date: Sat, 06 Sep 2008 16:50:06 -0600 X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-Id: <1220741406.6731.9.camel@localhost> Mime-Version: 1.0 X-Mailer: Evolution 2.22.2 Subject: [FASTCGI] A C++ FastCGI Library X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list Reply-To: eddie@mailforce.net List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 06 Sep 2008 22:50:22 -0000 --=-ldSO9QFm8d/6AE/7n5sz Content-Type: text/plain Content-Transfer-Encoding: quoted-printable Hey guys, I have been working on a pure C++ FastCGI library for some time now and have LGPLed it. I've got it up at http://fastcgipp.com for now. Lot's of good documentation and tutorials. I would definitely appreciate any ideas or comments you guys could offer. There are a few issues I am running into that I'm hoping someone could give me some insight into. For one, check out the upload example in the SVN trunk. For two, are there any plans to implement the ability to multiples requests over a single connection in mod_fastcgi? It just seems like there would be so much less overhead doing it that way as opposed to dealing with opening/closing numerous connections for every request. -- Eddie --=-ldSO9QFm8d/6AE/7n5sz Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEABECAAYFAkjDCR4ACgkQDzZhV8jFCCteIgCfbiN/c6qhWuCTHVzYB/xsyxr7 oRsAoI+vYdaxyEsi6yIV3Z7Zo0lbtWH/ =z9Hh -----END PGP SIGNATURE----- --=-ldSO9QFm8d/6AE/7n5sz-- From gcwf-fastcgi-developers@m.gmane.org Sun Sep 7 20:05:32 2008 Return-Path: Received: from localhost.localdomain (unknown [209.212.65.36]) by spam.chelsea.net (Postfix) with ESMTP id C0FCD1E32B for ; Sun, 7 Sep 2008 20:05:32 -0400 (EDT) Received: from real.pins.net (mail.chelsea.net [209.212.66.16]) by smtp.chelsea.net (Postfix) with ESMTP id 1066857A3 for ; Sun, 7 Sep 2008 20:05:28 -0400 (EDT) Received: from spam.chelsea.net ([209.212.65.24] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTP id 276181373 for fastcgi-developers@fastcgi.com; Sun, 07 Sep 2008 20:05:28 -0400 Received: from localhost.localdomain (unknown [209.212.65.33]) by spam.chelsea.net (Postfix) with ESMTP id 94D401E32B for ; Sun, 7 Sep 2008 20:05:28 -0400 (EDT) X-Spam-Checker-Version: SpamAssassin 3.2.5 (2008-06-10) on abita.chelsea.net X-Spam-Status: No, score=1.1 required=5.0 tests=BAYES_50, BOTNET, BOTNET_NORDNS, GOOGLE_PORN_LONGER, PINS_GAMBLE_BODY shortcircuit=no autolearn=no version=3.2.5 X-Spam-Level: * Received: from ciao.gmane.org ([80.91.229.2] verified) by real.pins.net (CommuniGate Pro SMTP 5.2.6) with ESMTPS id 276181344 for fastcgi-developers@fastcgi.com; Sun, 07 Sep 2008 20:05:04 -0400 Received-SPF: pass receiver=real.pins.net; client-ip=80.91.229.2; envelope-from=gcwf-fastcgi-developers@m.gmane.org Received: from root by ciao.gmane.org with local (Exim 4.43) id 1KcUFa-0001bF-Gs for fastcgi-developers@fastcgi.com; Mon, 08 Sep 2008 00:05:02 +0000 Received: from host81-153-214-79.range81-153.btcentralplus.com ([81.153.214.79]) by main.gmane.org with esmtp (Gmexim 0.1 (Debian)) id 1AlnuQ-0007hv-00 for ; Mon, 08 Sep 2008 00:05:02 +0000 Received: from richard_holland by host81-153-214-79.range81-153.btcentralplus.com with local (Gmexim 0.1 (Debian)) id 1AlnuQ-0007hv-00 for ; Mon, 08 Sep 2008 00:05:02 +0000 X-Injected-Via-Gmane: http://gmane.org/ To: fastcgi-developers@fastcgi.com From: Richard Holland Date: Sun, 7 Sep 2008 23:59:33 +0000 (UTC) Lines: 16 X-SMTP-Filter: YES X-Virus-Check: YES X-Virus-Check-Status: OK X-Virus-Found: No Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-Complaints-To: usenet@ger.gmane.org X-Gmane-NNTP-Posting-Host: main.gmane.org User-Agent: Loom/3.14 (http://gmane.org/) X-Loom-IP: 81.153.214.79 (Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.1.15) Gecko/20080701 SUSE/2.0.0.15-0.1 Firefox/2.0.0.15) Sender: news X-CGP-External-Filter: YES Subject: [FASTCGI] long process c application X-BeenThere: fastcgi-developers@mailman.fastcgi.com X-Mailman-Version: 2.1.11 Precedence: list List-Id: FastCGI application development and support List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 08 Sep 2008 00:05:35 -0000 Hi I am new to FastCGI and wonder if it can help in the following scenario. I am manipulating tape drives using C under linux and I want the things like tape status to be shown on a web page( after a button click) using the application as a CGI. The application fails/times out under CGI as tape processes take ages. Is FastCGI the answer here or do I press on looking at forking/child process etc in C.

Such timeouts should be entirely configurable, however, at least in apache and IIS.
