about CgiEnvironment and POSTDATA when using multiplexed FastCgi

In the CgiEnvironment constructor, it looks like it attempts to read all
of stdin.
FastCgi, however, chunks the stdin packets.

1) Is the read function, as defined in a subclass bridging a
multiplexing FastCgi with Cgicc, supposed to block until there
everything can be read, as done in the official FastCgi SDK's
FCGX_GetStr(FCGX_Stream*, char*, int)?
Or use EAGAIN / exceptions and wrap input->read in a for(;;)?
I'm using another FastCgi class because the fact that I'm threading
the processing means that multiplexing is the way to go to unleash the
performance of parallelism, and FCGX_* is not multiplexing-safe.
Note: the FastCgi instance class basically calls
std::string::append(input_buffer.end(), stdin_data, stdin_len). 
2) Is there an ability to limit the size of POSTDATA by using a function
hook? The non-virtuality of CgiEnvironment implies that implementing
this would require patch && make && sudo make install.

Note: I am not on the mailinglist. CC me when needed.

Cross building cgicc, getElements() app link error

Hello,
I built cgicc 3.2.8 using 2009q1 CodeSourcery ARM tools in
OpenEmbedded which built fine.  I was able to build and run the app
code below, but when I enable the getElements() section, I get a
linker error:
  hello.cpp:(.text+0x198): undefined reference to
`cgicc::Cgicc::getElements() const'

, which seems odd since getElements) is defined as inline in
cgicc/Cgicc.h.  I built the same app for x86 using g++ 4.4.1 and it
linked and ran fine.  Not sure if this is an issue with g++ or cgicc,
or can be patched in cgicc.  Anyone see this before?

Thanks!
,
John

int main(int argc, char **argv)
{
    Cgicc cgi;
    cout << HTTPHTMLHeader() << endl;
    form_iterator name = cgi.getElement("name");
    //if(name != cgi.getElements().end()) {
    //    cout << "Your name: " << **name << endl;
    //}

    return 0;

newbie question, help heeded

Hi!
I trying to develop highspeed web-service and i have some questions, and also i am not c++ programmer, this is my first cpp project.

I have this following code:
-------------------------------------------
#include <string>
#include "fcgi_stdio.h"
#include <stdlib.h>
#include <iostream>

void handle(FCGX_Request request){
        FCGX_FPrintF(request.out, "Content-type: text/html\r\n\r\n<TITLE>fastcgi</TITLE>\n<H1>Fastcgi: Hello world!</H1>\n");
}

int main(int argc, char* const argv[] )
{
    std::string port=":9001";       
    int listenQueueBacklog = 400;   
    FCGX_Stream *in, *out, *err;
    FCGX_ParamArray envp;
   
    if(FCGX_Init())    exit(1);

    int listen_socket = FCGX_OpenSocket(port.c_str(), listenQueueBacklog);
    if(listen_socket < 0)    exit(1);

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

    int reqCounter = 0;
    while(FCGX_Accept_r(&request) == 0)
    {
        handle(request);
        reqCounter++;
        FCGX_FPrintF(request.out, "\n\r\n\r counter: %d", reqCounter);
        FCGX_Finish_r(&request);
    }
    return 0;
}
-------------------------------------------

It works good listening 9001 port and serving resquests from nginx http server. I choose fcgi_stdio beacuse it can listen on tcp socket and it is simple to integrate it with nginx web server.

Question:
Can i use this configuration and include GNU Cgicc Library to access post field values, headers, cookie?
Anyone, please point to an example of using this both libraries in my case!

Thanks!

Upload files with demo upload.cpp

Hello,

  I'm trying to upload file with the demo we can find on the gnu website because I have to develop an application which has this utility. My problem is this, I cannot see where the file has been uploaded, I can only see what file contains, no more. I'm using ubuntu as principal tool, and xampp.

  I hope you could help me.

 Thanks a lot.

secure login code?

Has anyone put together a secure login form using cgicc?

I'm not really sure of the best way to start...

I've been looking at a lot of PHP login scripts (and WordPress logins), and I see roughly what I should be doing

but if someone has something to start with that they would be willing to share, that would be great...

Thanks

Matt

how access to HTML controls atributes ?

Hi,
 
I am new to cgicc library and I have a following problem.
I defined <select> HTML control like this:
 
cgicc::select sel1 = cgicc::select();

sel1.set("name","someName").set("class","selectfield").set("SIZE","1");sel1.add(br());

sel1.add(option(

"0/1").set("class","selectfield").set("value","1"));sel1.add(br());

sel1.add(option(

"0/2").set("class","selectfield").set("value","2"));sel1.add(br());

sel1.add(option(

"0/3").set("class","selectfield").set("value","3"));sel1.add(br());

sel1.add(option(

"0/4").set("class","selectfield").set("value","4"));sel1.add(br());
 
I would like to access to every embedded object (each option) inside sel1 object going through some loop, check value of
each option object and set "selected" atribute if needed.
 
I see that  HTMLElement object has HTMLElementList data which contains embedded object but it is private and it's possible to add new object into this list only.
There is no interface which provide accessing  i.e. reading and seting different atribute inside particular object ( in this case in "options" object inside "select" object) and I do not understand why it's like that.
 
Are there any other ways to access (and changes) atributes inside defined objects ?
 
Thanks in advance
 
V.

Interface to Remove Cookies


CgiCC HTTPCookies supports MaxAge that may be 0 (browser) or positive
according to RFC,

Other very important options Expires is not supported. This option is mostly
useless because requires
definition of absolute time. However one special case exists: Cookies
Removal.

In many cases it is very useful to remove cookies by setting Expiration date
in past.

I've written a little patch to fix this problem, please consider to merge it
into upstream

Sending Redirect and Status Headers


Hello,

There is two headers: HTTPRedirectHeader and HTTPStatusHeader. On of the
problems
with them is a fact that sometimes you should send them both

---------------------
Status: 302 Found
Location: /some/new/place

-------------------

Otherwise apache and nginx  would not redirect (only lighttpd works for me
without status header).
The problem is that each one of these headers adds "\n\n" at the and and you
can send them as is
So I should add Status header manually 

cout<<"Status: 302 Found"<<endl;
cout<<HTTPRedirectHeader("/some/new/place");

Is there way to send both headers together?

I don't see this option in the code, all render() virtual functions send
final "\n\n".

Thanks,
Artyom
