Pion Network Library (Boost licensed open source)

Pion Network Library

C++ framework for building lightweight HTTP interfaces

Project Home: https://github.com/splunk/pion

Retrieving the code

git clone https://github.com/splunk/pion.git
cd pion

Building the code

For XCode: use pion.xcodeproj

For Visual Studio: use pion.sln

On Unix platforms (including Linux, OSX, etc.) you can run

./autogen.sh
./configure

to generate Makefiles using GNU autotools, followed by

make

to build everything except the unit tests.

You can build and run all the unit tests with

make check

Generate build using CMake

CMake is cross-platform build generator. Pion required cmake version 2.8.10+

To generate build call

cmake <path to pion clone> [-G <generator name>] [-D<option>...]

for example to generate MSVS2012 Win64 solution run

git clone [email protected]:splunk/pion.git
cd pion/build
cmake .. -G"Visual Studio 11 Win64"

this will create pion_solution.sln for MSVS2012/Win64

if cmake can't find dependency, use -D to control Find modules search behaviour

-DBOOST_ROOT=<path to installed boost libraries>
-DZLIB_ROOT=<path to installed zlib>
-DOPENSSL_ROOT_DIR=...
-DLOG4CPLUS_ROOT=...

Third Party Libraries

Pion requires the Boost C++ libraries version 1.35 or greater. Please see the README.boost file within the doc subdirectory for instructions on how to download, build and install Boost.

For logging, Pion may be configured to:

• use std::cout and std::cerr for logging (the default configuration)

• use one of the following open source libraries:

  • log4cplus (recommended; --with-log4cplus),
  • log4cxx (--with-log4cxx) or
  • log4cpp (--with-log4cpp).

• disable logging entirely (run configure --disable-logging)

Detailed build instructions are available for all of the platforms supported by Pion within the doc subdirectory (README.platform).

pion's Issues

Replace logging macros by inline functions

Shouldn't the logging macros get replaced by inline functions? The currently needed all-upper-case macros look rather disruptive in otherwise all-lower-case code. IMHO. Can prepare a pull request if you agree that this deserves a look.

cmake CMAKE_SOURCE_DIR versus PROJECT_SOURCE_DIR

I am trying to integrate pion into a larger cmake-based project via add_subdirectory(pion pion-build).

This is rather difficult because the pion CMakeLists.txt uses CMAKE_ variables instead of the equivalent PROJECT_ variables. One unfortunate consequence is that the pion policy of not being able to build in-source escalates to the larger project.

If the pion CMakeLists.txt used the PROJECT_ variables instead, then I can build pion outside-source with the "pion-build" workaround in the add_subdirectory() above.

The variables that I needed to changes were:

• CMAKE_SOURCE_DIR -> PROJECT_SOURCE_DIR
• CMAKE_BINARY_DIR -> PROJECT_BINARY_DIR

And for good measure (see also #36) I also needed to remove the /Bin part of COMMON_BIN_PATH.

log4cxx as the Logger for pion-net

Hi,

The class log4cxx::Logger doesn't have a method called "get_logger". The right method is called "getLogger". You can see this in include/pion/logger.hpp.

Good job,
Tibério Menezes.

Building PION error: where to put boost libraries?

I did all from: https://github.com/cloudmeter/pion/blob/develop/doc/README.boost
but the last paragraph

"To install, you can now just copy the files in stage/lib into your
library include path, and copy the boost/ directory into your header
include path."
What does it mean? Where to copy those?

Thank you for any pointing into the right direction.

Set-cookie parsing

Hi,

I'm talking about:

bool parser::parse_cookie_header(ihash_multimap& dict, const char *ptr, const size_t len, bool set_cookie_header)
in src/http_parser.cpp

From what I understand this function was for breaking an individual cookie in its components and to put them in a dictionnary.

Well it seems this function is called for every cookie, that all individual components are mixed together and added as cookies themselves.

P. ex. , if I download one page, this is what a call to pion::http::response_ptr::write give me :

Set-Cookie: PREF=ID=b255244245f28df7:FF=0:TM=1407897815:LM=1407897815:S=p0ASItwZjDttyxBq; expires=Fri, 12-Aug-2016 02:43:35 GMT; path=/; domain=.google.fr

And as control this is what I get from wireshark:

request resource displayed without escaping in FileService error page html

The resource from the request is displayed in FileService's error html, such as the 404 page. Since the resource isn't escaped, it allows a possible XSS attack if you can get someone to click a malicious link. I found out about this from someone testing with nikto, and it seems to be the "Error Page Example" issue described here https://www.owasp.org/index.php/Cross-site_Scripting_%28XSS%29.

To fix it, I think all that would need done is to html escape the resource.

I'm using an old version of pion (3.0.5), but it didn't look like it has been fixed from a quick look at the latest version.

Compilation error in src/process.cpp when boost <= 1.44.0

I just tried to compile pion with boost 1.44.0. (I know it is an old version but this specific version is a requirement when building Adobe InDesign CS6 plugins.)
The error is introduced with the following commit:
9a3093d
where a line:
p.make_preferred();
was inserted.

As far as I have understood the boost code, make_preferred() is introduced with v3 of boost::filesystem.
So the line needs to be moved to after the following #if so it only takes effect when compiling with boost versions that use v.3 or higher. For boost version 1.44.0 and earlier which use v2 of boost::filesystem, this does not compile. In v.2 the return p.file_string() routine used in the #else part already does the conversion make_preferred() do in v3, so no changes for v.2 should be necessary.

So the fix should look like:

std::string process::generate_dumpfile_name()
{
...
     p /= ss.str();
     p.normalize();
-    p.make_preferred();

 # if defined(BOOST_FILESYSTEM_VERSION) && BOOST_FILESYSTEM_VERSION >= 3
+    p.make_preferred();
     return p.string();
#else
    return p.file_string();
#endif 

}

Cookies while writing a request

pion::http::message::append_headers function doesn't manage cookies, so with the following code:

////////////////////////////////////////////////////////////////////////////////////////
pion::http::request_ptr request(new pion::http::request);

// Setup the request method, resource, etc etc
...

request->add_cookie("JSESSIONID", "blahblahblah");

pion::http::request_writer_ptr writer =
pion::http::request_writer::create(connection, request, ....)

writer->send();
//////////////////////////////////////////////////////////////////////////////////

Will send the request but without Cookies.

Am I missing something or is this a bug?

I've temporarily fixed this issue replacing the function with:

inline void append_headers(write_buffers_t& write_buffers) {
// add HTTP headers
for (ihash_multimap::const_iterator i = m_headers.begin(); i != m_headers.end(); ++i) {
write_buffers.push_back(boost::asio::buffer(i->first));
write_buffers.push_back(boost::asio::buffer(HEADER_NAME_VALUE_DELIMITER));
write_buffers.push_back(boost::asio::buffer(i->second));
write_buffers.push_back(boost::asio::buffer(STRING_CRLF));
}

    // add Cookies

    ihash_multimap::const_iterator iend =  m_cookie_params.end();
    for (ihash_multimap::const_iterator i = m_cookie_params.begin(); i != iend; ++i)
    {
         write_buffers.push_back(boost::asio::buffer(HEADER_COOKIE));
         write_buffers.push_back(boost::asio::buffer(HEADER_NAME_VALUE_DELIMITER));
         write_buffers.push_back(boost::asio::buffer(i->first + "=" + i->second));
         write_buffers.push_back(boost::asio::buffer(STRING_CRLF));
    }

    // add an extra CRLF to end HTTP headers
    write_buffers.push_back(boost::asio::buffer(STRING_CRLF));
}

Please let me know if I'm following a wrong approach to send an http message or if it is really a bug.
Thx and congratulations for the powerfull lib.

Bug in HTTPWriter::send_more_data ?

There is a branch

    if (! m_tcp_conn->is_open())
        finished_writing(boost::asio::error::connection_reset);

at begin of method HTTPWriter::send_more_data.
Maybe "return" was lost here???

Because calling of "finished_writing(boost::asio::error::connection_reset)" here leads calling finishedWriting twice. One calling from this brunch and one later from callback initiated by m_tcp_conn->async_write.

Moreover if we detected non open connection at begining, is there any reason to execute buffers preparing, calling m_tcp_conn->async_write???

full code of send_more_data below:

inline void send_more_data(const bool send_final_chunk, SendHandler send_handler)
{
    // make sure that we did not lose the TCP connection
    if (! m_tcp_conn->is_open())
        finished_writing(boost::asio::error::connection_reset);
    // make sure that the content-length is up-to-date
    flushContentStream();
    // prepare the write buffers to be sent
    http::message::write_buffers_t write_buffers;
    prepare_write_buffers(write_buffers, send_final_chunk);
    // send data in the write buffers
    m_tcp_conn->async_write(write_buffers, send_handler);
}

Fallback for missing hash_map

If no hash_map was found, then the PION_HASH_MAP macro is not set appropriately, and compilation fails. I suggest that in such case, we fall back on boost::unordered_map.

See for instance https://github.com/breese/pion/commit/88b8c3e125aeef234e8e194d1e4401fbc351ffc2

Build with MinGW fails

Tried to build pion with MinGW (gcc 4.8.1) under Windows 7 64 bit (MSYS environment).
autogen.sh runs normal, but it generates configure file with two errors (probably one error duplicated) - there is empty else ...fi section at lines before line 17839 and 17938 (in my case). Had to remove lines with else.

After this issue is corrected configure runs untill it comes to boost library.

checking for boostlib >= 1.35... configure: error: We could not detect the boost  libraries (version 1.35 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option.  If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.

My boost library is located in non-standard location (actually I have several boost libraries of different versions). I had tried to define BOOST_ROOT environment variable as it is written in error message, but without success.

export BOOST_ROOT="/c/MinGW/boost_1_55_0/boost"

When i move folders with boost header files to include dir this test passes. But I do not know where should i put boost library (*.a) files.

I had also tried to define --libdir and --includedir in configure parameters without any success. (with ":" and " " as delimiters)

./configure --libdir="/C/MinGW/lib /C/MinGW/boost_1_55_0" --includedir="/C/MinGW/include /C/MinGW/boost_1_55_0"

It looks like there is no effect of this parameters on configure script execution
Could you help me to configure build environment?
Maybe I am doing something wrong.
I am very interested in pion library but still unable to build it.

cookie is not copied in copy constructor of class message

the m_cookie_params is not copied in message, so

    pion::http::response resp_1(req);
resp_1.receive(con, err); //  resp_1  contains cookie
pion::http::response resp_2 = resp_1; // cookie is not copied to resp_2

a boost 1.54 onward ' BOOST_SYSTEM_NOEXCEPT' compatibility

Hi, to build with other projects dependent on boost 1.54.0, I found I needed to alter two lines. Now I haven't then built with 1.53 or earlier to see what happens

boost::filesystem library... not found

I get the following error during my PION installation in Oracle Linux 5.5>

The curious is that others libraries can be found and there are in the same directory /usr/local/boost_1_45_0/stage/lib
(
checking for boost::date_time library... ok

Can anyone help me on this..
Thanks

tcp_server tries to gain admin rights for port 0

Not specifying a port number for tcp_server results in an ephemeral port number being selected by bind().

Unfortunately the initial port number of zero causes tcp_server.cpp:84 to try to gain admin rights where they are not needed. This causes an incorrect error in the log.

The check should probably be more like:

pion::admin_rights use_admin_rights((get_port() > 0) && (get_port() < 1024)); 

parser busy loop

Setting a payload handler callback on the parser produce sometime a busy loop around

http_parser.cpp line 58

do{
....
} while(boost::indeterminate(rc) && ! eof()) 

It seems to me that in the consume_content_as_next_chunk method the m_read_ptr has to be incremented also if m_payload_handler is set:

http_parser.cpp line 1450

if (m_payload_handler) {
            if (m_bytes_last_read)
            {
                m_payload_handler(m_read_ptr, m_bytes_last_read);
                m_read_ptr += m_bytes_last_read;
            }
        } else ....

With this change, my program is back to work fine

shared-lib-without-dependency-information and missing-call-to-setgroups

Hello!
I to build package (pion-5.0.7) and OBS output gave me the following warning:

pion-plugins.i586: W: shared-lib-without-dependency-information /usr/lib/pion/plugins/hasNoCreate.so

libpion-5_0.i586: W: missing-call-to-setgroups-before-setuid /usr/lib/libpion-5.0.so
This executable is calling setuid and setgid without setgroups or initgroups.
There is a high probability this mean it didn't relinquish all groups, and
this would be a potential security issue to be fixed. Seek POS36-C on the web
for details about the problem.

Thank you for the attention, hope this report helps development.

FileService caching does not allow deleted files

If a FileService plugin is used with caching enabled, the options can be set to allow newly added files. An improvement would be to check for deleted files.

cmake does not generate config.hpp

If you use cmake to generate makefiles on the develop branch, it does not generate include/pion/config.hpp resulting in the following error message in my own server:

/home/breese/src/transenna/remote/pion/include/pion/http/server.hpp:21:10: fatal error: 'pion/config.hpp' file not found
#include <pion/config.hpp>
         ^
1 error generated.

Plugins installed to wrong directory

The plugins are installed to the wrong directory. Currently they get installed to $datadir/pion/plugins (e.g. /usr/local/share/pion/plugins), which is for platform indepentent data files only. Plugins, like all other libraries belong to $libdir/pion/plugins.

Setting http::server::set_max_content_length has no effect

It seems that http:parser class doesn't receive a different max_content_length setted by http::server::set_max_content_length method. It use always the DEFAULT (1MB)

cmake find_package(Threads)

CMakeLists.txt currently uses find_package(Threads REQUIRED) to check for -lpthreads etc. However, some platforms have all the thread functions in the run-time libraries, and therefore have no extra thread library. The cmake build fails on these platforms because of the REQUIRED option. If you remove this option, then it works.

Limit number of concurrent connections

Hi,
would be possible to limit the number of concurrent connections?

I'm working on a solution to implement that feature but I didn't find yet a clean one.

My current solution:

• add a max_concurrent_connections member variable in tcp_server with default value = 0 and passed by the user in ctor.
• in server::listen , add a parameter bool histeresisTrigger with default value = false
• in server::listen , add the following check at the begin

if(histeresisTrigger)
{
    if((m_max_concurrent_connections) &&
    (m_con_pool.size() != m_max_concurrent_connections -10)) {
        return;
    } else {
         if ((m_max_concurrent_connections) &&
        (m_conn_pool.size() == m_max_concurrent_connections)) {
            return;
    }
}

• in server::finish_connection add the following code inside the else branch at the end :

if ((m_is_listening) &&
    (m_max_concurrent_connections) &&
    (m_conn_pool.size() == m_max_concurrent_connections -10)) {
        server_lock.release();
       listen(true);
    }

Do you think this feature would be useful?
Thx

silent fail + NULL = Segfault when using boost::sregex on result of decode

issued a pull request: #61

the preferred behavior might be a cleanup/exception or just an exception, but the current behavior is buggy and leads to unexpected results. this is what i propose, as not to expose a bunch of old code that depends on this behavior to start core-ing for the sake of correctness.

Websocket support

Any chance to have websocket technology support in pion?

Configure with --with-debug fails on OpenSuse 12.2 (couldn't find boost fileystem lib)

Hi,
configuring with --with-debug flag on OpenSuse 12.2 (g++ 4.7, boost 1.49), configure script fails with error:
Unable to link with the boost::filesystem library.

Removing the --with-debug flag everything works.
Leaving the --with-debug but skipping the test (editing configure script) everything works.

Generating documents fail

Hi,
Use "./configure --enable-doxygen-pdf " and "make all" to generate documents,but after that, can't find generated pdf files in doc.

System is Fedora16(x64), and doxgen has been installed.

External io_service

Is it possible to create an http server with an existing asio::io_service? If an application has an existing thread pool available could this be passed to a custom scheduler for example?

Embedded Pion server crashes on request handling

I'm embedding Pion in a small console application (MSVC-12.0). Unfortunately it crashes when handling a simple HTTP GET request.

I've built it with boost_1_57_0, openssl-1.0.2 and zlib-1.2.8 and no logging.

Here's a small example program reproducing the issue,

#include <pion/http/server.hpp>
#include <pion/http/response_writer.hpp>

using namespace pion;
using namespace pion::http;

struct test_server {
    void start() {
        m_server = pion::http::server_ptr(new pion::http::server(4500));
        m_server->add_resource("/", boost::bind(&test_server::handle_request, this, _1, _2));
        m_server->start();
    }

    void handle_request(http::request_ptr& req, tcp::connection_ptr& conn) {
        http::response_writer_ptr writer(
            http::response_writer::create(
            conn,
            *req,
            boost::bind(&tcp::connection::finish, conn))); // Crashes in this callback

        writer->write("hello world");
        writer->send();
    }

    pion::http::server_ptr m_server;
};

int main() {
    test_server svr;
    svr.start();

    while (1) {
        Sleep(0);
    }
}

It crashes in the &tcp::connection::finish callback with the following stack trace,

How to start pion web server?

Hi,

After installing pion in ubuntu, i couldn't start pion server using "sudo ./start_pion.sh -D" command.
Infact start_pion.sh is missing in setup files.

Also in windows, "PionWebServer" file is excluded.

pls guide for the same.
Thanks

cmake and bzlib

If you have bzip2 installed, but not libbz-dev, then cmake will pass just fine, but a subsequent configure will fail to find the header files.

make install doesn't copy config.hpp

make install doesn't copy the file include/pion/config.hpp

Does the pion server support compression via the 'Accept-Encoding: gzip' directive?

I built the pion 5.0.6 library with zlib support and wrote a sample HTTP server. The server is a dummy server that always returns a JSON payload.

When I issue a HTTP get request to the server with "Accept-Encoding: gzip" set in the header, I was hoping to get gzipped JSON in the response but server always returns plain JSON.

Am I missing something here? Do I need to set a parameter on the pion::http::server that will turn on the gzip support?

FileService bug for directory option with trailing slash

Using the FileService with pion v5.0.7 and boost filesystem V3:

m_server.load_service("/resource", "FileService");
m_server.set_service_option("/resource", "directory", "/some/trailing/slash/path/");

Results in an unusable FileService. Because the FileService stores this path normalized which would be /some/trailing/slash/path/.

If some request is handled by the FileService the file path is constructed (see

pion/services/FileService.cpp

Line 146 in 96c8e45

file_path = m_directory / relative_path;

)

For example file index.html reconstructs to /some/trailing/slash/path/./index.html which later is normalized to /some/trailing/slash/path/index.html. The function then checks if the file is in the directory (with string::find) but fails because of the normalized resource directory (mind the extra dot there).

Also mind that boost::filesystem::path::normalize() is set to deprecated.

parse_multipart_form_data corrupts binary file

Hi,

//const char *next_ptr = strstr(ptr, boundary.c_str());
const char *next_ptr = std::search(ptr, end_ptr, boundary.begin(), boundary.end());

strstr will stop at the null character, hence it will fail to find the boundary marker, and the latter will be appended to the file

Hope it helps,
alex

How to start pion web server?

behavioral change with parse_uri?

Hi,

I've been using parse_uri to decide if there is a uri and if not do something different.
Previously
std::string potentialUri="ethanol.xml"
would reject and let me know it wasn't a uri

        if(!pion::http::parser::parse_uri(uri, proto, host, port, path, query))
        {
            return false;
        }

but not it satisfies but there is no host or port;
Maybe I should now decide on the results instead of the return boolean?

Good documentation / tutorials

Any links to good documentation or tutorial for starting with pion? Also I would like to know if we can do async long io with this library?
