Re: fcgi_i/ostream - deprecated?

Ooops....apologies, looks like this problem has something to do with
my libcurl-based load test app and not the fcgi_streambuf peek().
Thanks for the tips, though, I did switch to mod_fastcgi.

Missing env variable using cgi-fcgi standalone

I am testing the my application using cgi-fcgi as a standalone, and
although the application runs some enviromental variables are missing
in the context of the application.
Specifically, REMOTE_USER, which comes from Apache's Auth*
configuration.  Any ideas what might be causing this? (The application
itself is perl)

Re: Missing env variable using cgi-fcgi standalone

We wrapped it in a bash script to test it, I'll check but I'm
uncertain as of yet what the problem is.

Patch for "Symbol not found: _environ" on Mac OS X

Hello all,

First off: I'm new on this list but have been developing with libfcgi
for about four years now.

Recently a bug was discovered when Python 2.5.4 was updated in
MacPorts – libfcgi relies on extern char **environ on Mac OS X, which
does not exist. I know, it's really sick Apple does not export it
POSIX-style. However, the ugly bug fully correct fix is to #define
environ (*_NSGetEnviron()).

I've only tested FCGI on Windows/IIS, but have you tried getting 
FCGI::IIS to run? I has a test mode which should work on Apache as well.

Also it might be worth trying CGI::Fast

Re: (4)Interrupted system call:

Try upgrading to the latest snapshot of 2.4.7 at 
http://www.fastcgi.com/dist/mod_fastcgi-SNAP-0811090952.tar.gz. I have 
had these problems too. They are fixed now.

Thanks for the answer but :

I run Vista Home Basic edition where IIS is not really supported by MS 
The goal is just to have a simple dev platform.
On production it will run on linux and hopefully work!

Same error

So to sum up :
- mod_fastcgi w apache2.2 not working on windows (everyone complains about 
same errors like me and I didnt see
any good solution given by anyone to fix it)
- IIS + fastcgi not possible on vista basic edition

Any advice : lighttpd or thttpd ?

Manu,
  Unfortunately at this point I haven't had change to work through all 
the fcgi setups, and write guides like I've been planning.
 I'm held back on a very large project and having to pay bills :(

  Hopefully I've have chance in the next couple of months, but I can 
understand that's far off for you :(

I'd give lighttpd a go. Let us know if you manage to get a solution. If 
the worst come to the worst you could always dual boot Linux, or try cygwin.

Length Incosistency Between FCGI_RECORD and FCGI_PARAMS

Hi,

AFAIU, FCGI_PARAMS are wrapped in FCGI_RECORD data types. (Please
correct me if I am wrong.) And there are four types of FCGI_PARAMS
message formats with variable length headers:

  1. {KEY-LEN[1], VAL-LEN[1], KEY[KEY-LEN], VAL[VAL-LEN]}
  2. {KEY-LEN[1], VAL-LEN[4], KEY[KEY-LEN], VAL[VAL-LEN]}
  3. {KEY-LEN[4], VAL-LEN[1], KEY[KEY-LEN], VAL[VAL-LEN]}
  4. {KEY-LEN[4], VAL-LEN[4], KEY[KEY-LEN], VAL[VAL-LEN]}

But an FCGI_RECORD message header format is of fixed length. Now
consider below message:

  {VERSION    [1],
   TYPE[1],                  // FCGI_PARAMS Type
   REQUEST-ID [2],
   CONTENT-LEN[2],
   PADDING-LEN[1],
   RESERVED   [1],
   CONTENT    [CONTENT-LEN], // {KEY-LEN[4],
                             //  VAL-LEN[4],
                             //  KEY    [KEY-LEN],
                             //  VAL    [VAL-LEN]}
   PADDING    [PADDING-LEN]}

Whole record length is represented by 2 bytes (maximum 2^(2*8) bytes),
but a key+value length might be representing a block of 8 bytes (maximum
2^(4*8) bytes) in size.

  +-----------------------------+
  | ### FCGI_RECORD ########### |
  | +----------------------------------------------+
  | | ### FCGI_PARAMS ############################ |
  | +----------------------------------------------+
  +-----------------------------+

  ^                             ^                  ^
  |---- 2^(2*8)=65536 bytes ----|                  |
  |--------------- 2^(4*8)=4294967296 -------------|

How can this be possible? I have read FastCGI specification[1] over and
over again but couldn't find a clue. Would you mind helping me to
clarify this point please?

Regards.
