Delete me! Sorry, I was mistaken.

Thanks!

it does segfault in http.cpp, fastcgipp version 2.1 in
void Fastcgipp::Http::Environment::parsePostsUrlEncoded()

I did not figured out how to fix it yet.

1. The code to set non-blocking mode sets blocking mode instead. Re-read the one-liner you use:

fcntl(listen, F_SETFL, (fcntl(listen, F_GETFL)|O_NONBLOCK)^O_NONBLOCK);

It gets current socket flags, appends O_NONBLOCK to them with logic OR, and THEN, for some reason, does XOR with O_NONBLOCK, which leads to dropping of O_NONBLOCK flag).

2. Several places where invalid iterator (end) is dereferenced:

• Fastcgipp::FcgiStreambuf<wchar_t, std::char_traits<wchar_t>>::emptyBuffer()
  &*record.end() - it's wrong to do this.
• void Fastcgipp::Http::vecToString(
  string = converter.from_bytes(&_start, &_end); - DITTO

3. Bad reinterpret cast:
   reinterpret_cast<uint16_t>(write) = 0xffff;
   should be
   reinterpret_cast<uint16_t>(&*write) = 0xffff;

4. Vector iterator reused between different vectors (which is not allowed):

In template void Fastcgipp::Http::decodeUrlEncoded(

nameEnd is first used as

auto nameEnd(dataEnd);

but later is resued in this statement:

            nameEnd = percentEscapedToRealBytes(
                    nameStart,
                    data,
                    buffer.begin());

Where it becomes an iterator from "buffer".

I'm sure there are many more errors here, but at this point, I kind gave up, this library is not ready to be used in production.

At the moment the server will return a 500 server error if unknown POST data is received.
But sometimes you want to receive it (e.g. when getting json).
In this case I would like to simply access the post buffer and work with the raw data (parse the json with my Request class).

Hi @eddic：
I cloned fastcgipp，and compile it successfully，then，I run make helloworld.fcgi to generate executable. But I found it listen none port, no bind syscall used, and listen complain "illege seek" error. My question is how run it correctly

I compiled the example echo.cpp, launched with spawn-fcgi. and set up nginx

But when I accessed it in browsers, although it replied the correct webpage, most of time, it replied 504 error

Sometimes it crashes.

Do you have any suggestions?

Was getting a "Socket read() error on fd 8: Resource temporarily unavailable" when uploading files larger than ~500kb using the library being an nginx proxy. (nginx throws a 502 to the client and "writev() failed (32: Broken pipe) while sending request to upstream" to the error log)

Adding a hacky retry loop that's around the read call (socket.cpp:74 - commit fc9bfc4) seems to fix the issue for my purposes (can upload 20mb+ now) - but I didn't track down the underlying cause.

Hope this helps,
Cheers

Since there's no PATH_INFO param in what nginx send to gnu.fcgi.
the following condition is always false.

possible solution is to use requestUri, since the URI is not started with gnu.png, so use find() here.

possible patch:
(the cmakelist.txt change is for debian stable which still uses cmake 3.7 that does not support target_compile_features(fastcgipp PRIVATE cxx_std_14),
just FYI if you're willing to make it build with cmake 3.7)

Is there a way to get the raw FCGI Parameters? Your Environment class auto-parses most of them, but it is missing a few that we use. How do I access the raw FCGI parameters of a request?

Hello,
I am not familiar with cmake; I just know how to run it.

I am however very familiar with Linux on the command line.

It would be nice if we could make libfastcgipp.a because of various C++ ABI issues on Linux (e.g. the libstdc++.so could be different on my Linux laptop and on the Linux VPS I am renting).

BTW, I could soon use libfastcgipp.so in the http://refpersys.org/ project

As the title gives: use of undeclared identifier 'HOST_NAME_MAX', when cmake, make under OS X 10.11.6

Following the build instructions, I got 2 compilation errors, both about variables ("buffer" and "padStart") on the same line in the file http.hpp. The variables could possibly be used without an initialisation.

using fastcigpp,i can get standard headers,such as HTTP_HOST,HTTP_COOKIE,SERVER_ADDR etc. how can i get user defined headers,such as xxx_header1,xxxx_header2 etc.

any plan to support mysql8? specifically the mysqlx plugin/protocol for RDBS+Document Store.

When I was in vs2013 compile fastcgipp - master/examples under the helloworld, tip unable to open include file: "fastcgi++ / config. HPP" : No to the file or directory I really don't have the file view under the directory

in src/sockets.cpp:
m_data(new Data(-1, false, *static_cast<SocketGroup*>(nullptr))),

I have the following situation (fastcgi server):
When a request comes in, I push off all handling of the request to a threadpool and wait for a Fastcgipp::Message to be returned from a function.

If the connection is closed (e.g. if the server/clients's timeout is reached) the request's destructor is called which invalidates things like the request's environment.

If I then try to access the environment from the threadpool thread my process can segfault.

Would it be possible to either:

• make the Request's environment moveable and add a non-const reference to the environment
• make the Request's various post/get/file/other attributes movable and add a non-const reference to the environment
• add a method to move or copy if necessary the various post/get/file/other attributes to a new Environment
• make the Request's environment a std::shared_ptr so that it sticks around as long as it has a reference (adds overhead)

The example app mail.fcgi will inifinitly retry with bad sender address.
I found thousands of fail logs after input a bad send address, I think this might be a trouble to your server.

If I wanted to access an environment variable like the script_name and then use that to determine which class to hand to the Fastcgipp::Manager would be the simplest way to go about doing this? I'm using v 2.1

The library uses Thread::Thread and therefore calls find_package(Threads REQUIRED).

The problem is, that it only calls it on it's own CMakeLists.txt and not within it's FastcgippConfig.cmake.

This results in an error running cmake configure on a project which is using Fastcgipp but not Thread in first place:

 ...
  Target "FastCgi" links to target "Threads::Threads" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?
...

I seem found a problem with the Session Example.
Session.fcgi were not share the s_sessions in different process.
I had open 25 process to launch the Session.fcgi ,
When I reflash the Site too fast , the nginx will use other process(because the first process is using)
and then the session size is zero in second process.

The FastCGIPP::SocketGroups::listen( const char*, uint, const char*, const char*) fails
to create a file for the socket that can be referenced by NGINX fastcgi_pass directive.

Start a FastCGI with the following line to create a socket ...

    const char* sockfilepath = "/tmp/hello.sock" ;
    manager.listen(sockfilepath,  0xffffffffUL, "nobody" ) ) ;

Simple NGINX config.

http {
   server {
        location /hello {
           fastcgi_pass unix:/tmp/hello.sock ;
        }
    }
}

Results in the following error.

This is on Centos 6.8 with devtoolset-4 and cmake3 installed.

I changed both instances to use if(events & pollIn) and compile worked.
I haven't tested the binary produced but I assume it'll work as you only want to check if the EPOLLIN bits are set in the events.

I had written a small web server using this library. I used to compile the program using shell scripts and it worked because I directly linked with -lfastcgipp. As a part of my refactor, I want to use build systems (for obvious reasons). I chose meson which could not find fastcgi++. I learned that the pkg-config was not able to find fastcgi++. This is the output of pkg-config --cflags --libs fastcgi++

Package fastcgi++ was not found in the pkg-config search path.
Perhaps you should add the directory containing `fastcgi++.pc'
to the PKG_CONFIG_PATH environment variable
Package 'fastcgi++', required by 'virtual:world', not found

Note: The PKG_CONFIG_PATH variable is empty

A quick google search about pkg-config fastcgi++ brings me to the documentation of fastcgi++ 2.1 which states:

A pkg-config file will be installed so you can compile against the libraries with
g++ -o script.fcgi script.cpp pkg-config –libs –cflags fastcgi++

But the documentation of 3.0 does not state that.

I installed fastcgi++ as mention in the readme without SQL support. have I done something wrong? Or is the support removed in verison 3?

Thanks for a great library.

To get this to compile on OSX, can you add to the top of sockets.cpp

#ifndef POLLRDHUP
#define POLLRDHUP 0x2000
#endif

#ifndef MSG_NOSIGNAL
# define MSG_NOSIGNAL 0
# ifdef SO_NOSIGPIPE
#  define CEPH_USE_SO_NOSIGPIPE
# else
#  error "Cannot block SIGPIPE!"
# endif
#endif

And add to log.cpp:

#if __APPLE__
    #ifndef HOST_NAME_MAX
        #define HOST_NAME_MAX 255
    #endif

    #ifndef program_invocation_name
        #define program_invocation_name "fastcgi"
    #endif
#endif

I am having multiple issues under Ubuntu with gcc 5.4.0.

After running make and make install, I try to build the examples. However, I get this error:

#error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

I didn't see any warnings/errors prior. Is there something I am missing?

Hi,

when receiving a request, if the query string ends by separator "&", the separator is added to the last value:

http://localhost/doc?p=a&

p is set to "a&" instead of "a".

C++ code showing the problem:

#include "fastcgi++/http.hpp"
#include <iostream>

int main()
{
    const char input[] = "p=a&";

    std::multimap<std::wstring, std::wstring> output;
    Fastcgipp::Http::decodeUrlEncoded(
            input,
            input+sizeof(input)-1,
            output);

    for ( auto & parameter : output )
        std::wcout << parameter.first << "=" << parameter.second << std::endl;
}

when i make fastcgi++,it's failed.It needs the header file ,but I could not find this file.I tried to update libstdc++ by 'yum',but it told me is lastest.
so how can I get the file codecvt to slove this problem?

Using setsockopt SO_REUSEADDR (or SO_REUSEPORT if Linux >= 3.9, I'd assume yes these days) before bind/listen can make it so that a server that segfaults can start listening right away. I didn't need to worry about this on 2.1 because I used the spawn-fcgi program which I never got to segfault. A great description of these options and how they differ between operating systems it is on stackoverflow.

Using gcc 7.3.0 on Ubuntu 18.04 (32 and 64 bits), the fcgistreambuf_test program throws a "pure virtual method called" error when the destructor of streambuf is called. gdb shows:

#5  0x00007ffff77d980f in __cxa_pure_virtual () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6

#9  0x000055555555a99e in main () at ../fastcgipp/tests/fcgistreambuf.cpp:312

It seems it is because base class WebStreambuf destructor calls sync which calls emptyBuffer which is a pure function defined in the parent class FcgiStreambuf. And since destructors are called in sequence, FcgiStreambuf is already destroyed when WebStreambuf destructor is executed.

Was working fine in previous versions where sync was called from FcgiStreambuf destructor (tested with commit 3bf169a).

...
fastcgipp/src/sockets.cpp:547:25: note: in expansion of macro ‘FAIL_LOG’

This is just one example. Using the lock_guard called lock shadows any other variable called lock. You could use a variadic template instead and acheive the same results. Just use , instead of <<. I can submit a PR if you want.

Am I safe to assume from request.hpp#L36 there should be an exceptions.hpp in https://github.com/eddic/fastcgipp/tree/master/include/fastcgi++ ?

Is there a way to process post data of content type: application/json
I keep getting a warning in my apache2 log file
[warning]: Unknown content type from client

Hi!
Examples doesn't work. Any time run i receive error: "[error]: Unable to listen on default FastCGI socket: Socket operation on non-socket".
sockets_test is pass ok.

Part of modern CMake is exporting a ProjectConfig.cmake file and installing to lib/cmake/project. It would be nice for CMake users to be able to simply:

find_package(Fastcgipp REQUIRED)
add_executable(foo foo.cpp)
target_link_libraries(foo PRIVATE Fastcgipp::fastcgipp)

Building the examples finishes with the error:

/usr/local/include/fastcgi++/request.hpp:36:36: fatal error: fastcgi++/exceptions.hpp: No such file or directory
compilation terminated.

exceptions.hpp was really deleted in 09b65f4

Compiling with GCC 5.3.1 or 6.1 on an i586 openSUSE machine the build always exits with an error:

src/request.cpp:106:64: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]

[ 108s] /home/abuild/rpmbuild/BUILD/fastcgi++-3.0beta/src/request.cpp:106:64: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]

The reason is that contentLength is unsigned and m_maxPostSize is ssize_t.
A solution would be to use size_t instead of ssize_t and use std::npos instead of -1 (ok they are quite equal ;-) ) to determine if unlimited or not.
