Hi, I succeeded compiling in ubuntu 16.04, tried to test echo_client and echo_server but got an error
I read EXAMPLES.txt but failed to solve
I want to know how to use

Since yesterday I can't build the windows version anymore (Linux still works)
I get an "Error C2220 warning treated as error - no 'object' file generated lshpack.c line 5354" error and the following warnings:

Changing to the commit from 27/4/2018 fixes this problem so I believe this is a regression in the latest changes.

Can the -P parameter supports to post some string?

I'm not able to build.

Compile the library

cmake -DBORINGSSL_INCLUDE=$BORINGSSL_SOURCE/include \
                                -DBORINGSSL_LIB=$HOME/tmp/boringssl-libs .
make

Appears that error:

/usr/local/lib/lsquic-client/src/liblsquic/lsquic_parse_iquic_common.c:8:10: fatal error: openssl/rand.h: No such file or directory #include <openssl/rand.h> ^~~~~~~~~~~~~~~~ compilation terminated. src/liblsquic/CMakeFiles/lsquic.dir/build.make:206: recipe for target 'src/liblsquic/CMakeFiles/lsquic.dir/lsquic_parse_iquic_common.c.o' failed make[2]: *** [src/liblsquic/CMakeFiles/lsquic.dir/lsquic_parse_iquic_common.c.o] Error 1 CMakeFiles/Makefile2:172: recipe for target 'src/liblsquic/CMakeFiles/lsquic.dir/all' failed make[1]: *** [src/liblsquic/CMakeFiles/lsquic.dir/all] Error 2 Makefile:94: recipe for target 'all' failed make: *** [all] Error 2

thanks, Davide.

Hi, I am using lsquic v1.2 release, and I slightly modified your code to use lsquic as a general purpose translating library.

But I found when I invoke lsquic_engine_destroy function, the program crashes.

On mac and linux, it it sometimes crash, and on windows (by refering your master brach, I ported it to win32), it crashed every time.

when I invoke lsquic_engine_destroy, the program finally dies at the last line of lsquic_malo_destry function (but the 'page' variable is not NULL).

What should I do? Is there anything I should take good care of to use lsquic correctly?

Thank you!

BTW, I don't konw how to use your latest code because I found your master's document is out of date. And I found some comments in the code are out of date, too. Could you please update the document?

How can I replace pfnWSASendMsg and pfnWSARecvMsg to let lsquic work at Windows XP?

Hi all,
it's about a week that i'm looking inside the http_client.c code for being able to modify the client with the function that i need, but without any success.
I'm pretty new in this things, so it's a bit hard for me to understand all the code.

Let me explain my idea of project:

1. A client that every X ms send a string formed like this "Name of the client - Random Value - Timestamp"
2. A Server that is running that, as soon as recieve the string, just output it on a page

Actually i have done a client and a server on php that was working like i wanted, but was not be able to use QUIC protocol, instead it was using UDP. Then someone suggested me to look into this Client to be able to do that work.

I will leave my old php client and server code as a reference
Client:

$server = "X.X.X.X";
    $port = 443;


    $controllerSensors = new ControllerSensors();
    $controllerSensors->createSensor("Sensore Bologna", "Temperatura", $server, $port, 1);
    $controllerSensors->createSensor("Sensore Modena", "Temperatura", $server, $port,4);
    $controllerSensors->createSensor("Sensore Reggio", "Umidità", $server, $port,8);
    $controllerSensors->runAllSensors();

Where runAllSensors() is a function that call sensor->start() in all sensors

Sensor Start function:

if(!($this->socket = socket_create(AF_INET, SOCK_DGRAM, 0))){
                $errorcode = socket_last_error();
                $errormsg = socket_strerror($errorcode);
                die("Couldn't create socket: [$errorcode] $errormsg \n");
            }
$input = $this->toString();
            if( ! socket_sendto($this->socket, $input , strlen($input) , 0 , $this->ip , $this->port)){
                $errorcode = socket_last_error();
                $errormsg = socket_strerror($errorcode);
                die("Could not send data: [$errorcode] $errormsg \n");
            }

Server:

$ip = "0.0.0.0";
    $port = "12345";

    error_reporting(~E_WARNING);
    if(!($sock = socket_create(AF_INET, SOCK_DGRAM, 0))){
        $errorcode = socket_last_error();
        $errormsg = socket_strerror($errorcode);
        die("Couldn't create socket: [$errorcode] $errormsg \n");
    }

    // Bind the source address
    if( !socket_bind($sock, $ip , $port) ){
        $errorcode = socket_last_error();
        $errormsg = socket_strerror($errorcode);
        die("Could not bind socket : [$errorcode] $errormsg \n");
    }

    while(true){
        $messageRecieved = "";
        $r = socket_recvfrom($sock, $messageRecieved, 512, 0, $remote_ip, $remote_port);        
        echo $messageRecieved . "<br>";
    }

All those code was working like i wanted, but like i said, it was using UDP instead of QUIC.
Now, i would like to have a similar behavior but using lsquic-client to be able to use QUIC.

But i'm facing a lot of problems:

1. i'm unable to understand where i should put the new code to make the client works like my php client, so that send a "packet of information" to my server that is actually coded in php(i highly prefer it's coded in PHP, but i can change that as soon as Litespeed Web Server support it)
2. I tried to build the http_client using the gcc command from the terminal but without success, what are the parameters for the gcc command?
3. It's possible to do something like this?

I'm sorry for the long post and for the continuous request for help, but it is an important thing as it concerns my triennial thesis and I think that more information is present to describe the problem the easier it will be to find a solution.

Thanks,
Davide.

I see a some documentation available for http3 client, but I couldn't find any for the server.

• Are there any documentation available on how to start the http3-supported web server?
• Another noobish q, will this package need Lite Speed to be built before using lsquick? Essentially I want to setup a machine as a http3 supported web-server to conduct some academic experiments.

Thanks

Where can i find the documentation about this client? Like a graph that show the structures, how each class interact with the other etc?

Thanks, Davide.

Hi all,

Is there any plan to support on Android, iOS and Windows?

I have got a build error when test/prog.c was compiled.
The c source file is including the event2/event.h header file is not found in the project.

Can anybody check it for me?
Thanks

I am currently trying to compile the lsquic client on a windows 10 system using your guide: guide

All the steps until the compilation in windows studio 2015 did work.
Once I tried compiling the client I got numerous errors. (who where all not solved by multiple building)
First an error that says invalid numeric argument '\Wextra'
Wextra
I could "fix" this one by commenting a line in the CMakeLists.txt file as it seems to be a flag that should only be set on linux systems from what I can tell.
The next error(which appeared after compiling again) said "invalid numeric argument '\Werror' "
Werror
Same fix as the previous error.
CMakeLists.txt
After that I got even more errors (I think most of them are the once mentioned in the guide)
The outstanding error again said: "invalid numeric argument '\Wno-unused-value' "
Wno
Unfortunately I couldn't fix this one since it did not appear in the CmakeList.txt file.

Now I don't know whether this is a problem on my end or with the client so if somebody understands these error codes it would be nice if you could help me out.
The bug happended on both debug and release on a x64 machiene.

I followed the installation instructions as mentioned here:
https://github.com/litespeedtech/lsquic/blob/master/README.md

while building BoringSSL module, I got this error when I was executing:
patch -p1 -i ../patches/boringssl-meds.patch
which says file not found
Later I found that it is in lsquic, so I think in the instructions lsquic needs to be downloaded first, and then the previous line needs to be changed to:
patch -p1 -i ../lsquic/patches/boringssl-meds.patch

I compile project in win7, then I use command "http_client -H www.example.com -s 169.254.0.3:8443 -p /1.txt -L debug" to visit my web server on another machine(ubuntu 16.04), but no reponse can be found.
but I use chrome to visit my web server, It works well.

Does lsquic-client implement CUBIC congestion controller?
Is it possible to observe a packet pacing, as it was presented on one of Google presentations?

When trying to execute lsquic using the standard example in EXAMPLES.txt in Debug mode the program will crash with an Assertion Failed Error as shown in the picture above. I doesn't matter wether ipv4 or ipv6 is used. The error happens in lsquic_engine.c


These are the flags that are shown in the debugger.

When executed in release mode the programm will just go into an infinite loop.
Since it is about flags again it might have something to do with issue #10

when I cd lsquic-client and make,the errors as below,it seems that my libevent version is not suitable,but I don't know how fix it
[ 35%] Linking C executable http_client
CMakeFiles/http_client.dir/test/http_client.c.o: In function create_another_conn_or_stop': /home/b/quictest/lsquic/lsquic-client/test/http_client.c:292: undefined reference to event_free'

I'm not sure, but there might be an issue, connected with maintaining multiple connections at the same time. I've tried to connect to the www.youtube.com(172.217.21.238) and www.google.com (216.58.213.228). But for the first one there is connection handshake established, for the second one not. In case of downloading a single www.google.com - connection is successful.
After creating an engine, all connections are created, then streams. After that lsquic_engine_process_conns is called. It seems like both connections send their hello packets on event packets_out, but response is processed only for the one. For the other one there is connection ID mismatch.
So finally there is a problem of storing 2 connections for the one engine at the same time.

How can i proprerly assign multiple variable inside the GET request? When i run that command it return an error.

[3]+  Done                    Temperatura=38

Second question: -n is for multiple connection, -r is for the number of request to send and -R is the max request a connection can send? So, if i run the command like the above one, i will have 3 connection which send 3 request each?

Thanks,
Davide.

Configure your build as follows:

install valgrind on your workstation
sudo apt-get install valgrind

Add to line below enable_testing() in the test/unittests/CMakeLists.txt
find_program(CTEST_MEMORYCHECK_COMMAND NAMES valgrind)
this will generate DartConfiguration.tcl in your build dir

from build folder execute memcheck on the unittests
ctest test -T memcheck -V

Hi,
I have used your platform to do large blob downloads (e.g. 1G) files and force the browser to not exceed more than 1 parallel connection for download.

I see that HTTP 3 is much faster than HTTP 2 and 1.1.
For instance,
HTTPS 1.1 took 55 seconds
HTTP 2 took 50 seconds
HTTP 3 took 35 seconds.

Can anyone explain:

• Why HTTP 2 is faster than HTTP 1.1?
• Why is HTTP 3 faster than HTTP 1.1 and HTTP 2?

I know the overheads, but such high difference is what I am not sure.

Any thoughts?

Arvind

For my example of using lsquic library it's required to download sequentially pairs of web pair resources, but for the same hostname. So after downloading first 2 urls in parallel there is the next pair. Should I use the same created pair of "lsquic_stream"s? Or is it better after reading 0 bytes from http_client_on_read event, close used streams and create new ones for next pair of urls?

Hi I'm trying to build the LSQUIC Client Library but make fails when compiling the ibrary. I'm using xubuntu 18.04 Bionic Beaver. This Is the beginning of the error that I receive

[ 34%] Built target lsquic [ 34%] Linking C executable http_client CMakeFiles/http_client.dir/test/http_client.c.o: In function sk_X509_num':
/home/jessix/boringssl/include/openssl/x509.h:269: undefined reference to sk_num'

Now I know this is not neccessarily an issue but one thing that makes it challenging to work with the source code is the lack of comments within it. Without comments you often have to reengineer the code yourself find out what functions do and how they are supposed to be used which can become a rabbithole quickly if these functions than call a bunch of other functions.

I might help out with this once I have a proper understanding of the code but right now I am mostly guessing what functions do.

Since I don't think it deserves an own thread I'll put it here. In line 332 http_client.c somebody forgot to remove some debug code I think:
#ifndef NDEBUG const int s = #endif

I also have a question that I don't know where to ask so I'll put it here.
Is there (and where :) ) some kind of data structure that stores the server response and meta infos like quic version used etc. that I can access from the main function?

I just noticed that one of the changes that was made in merging my Windows pull request was to separate unittests by MSVC and not MSVC, instead of defining compiler flags by the same and keeping the list of tests common

My concern is that this makes it easy to miss for Windows any new tests that get added. I think I already found a test_frame_rw that should be compiled for windows but is not.

version negotiation always fail with both http_client and echo_client if server only support gquic.

take http_client as an example,

linxiaocong@CHARLIELIN-MB0 build % ./http_client -s www.google.com:443 -p / -M HEAD -l conn=debug

if manually set the quic version, it will succeed.

Is it possible to have a quic server and a quic client in the same process? I noticed "lsquic_global_init" requires a flag that specifies whether the library is used in server mode or client mode globally. Does that mean you cannot have a connection accepted from a server creating a separate client connection, because of the global initialization?

Hi,

I am trying to using ./http_client to talk with my quic server, but it returns this error to me
[ERROR] [QUIC:12718164802224998270] conn: Abort connection: client does not support any of the server-specified versions
The command that I am using for is
./http_client -t -H sni.com -s 10.11.0.122:4433, which SNI is stored in my default SSL file and I am using TLSvs1.3.

This test failed on both master and ietf-base-draft-20 branches.

Do you guys have any recommendation on that.

According to the installation documentation, I started to compile Isquic-client after installing the boringSSL library. When I went to the make step, I got the following error. I don't know what the problem is.

Here is my OS version (macOS High Sierra 10.13.3), Thanks for any help.

Great work here! I would love a Dockerfile to build this all. I'll submit a PR if I get a chance to create one.

I built lsquic within a Ubuntu 19.04 docker container on CentOS 7 docker host, but when i try

 http_client -s www.google.com  -p /

it just hangs and doesn't return to prompt or output anything

if i run

 http_client -s www.google.com  -p / -L debug

I get 100s of lines with following message

23:16:32.478 [DEBUG] engine: send_packets_out: sent 0 packets

so do I need additional steps for running within a docker container image ?

Reported by @Kait0.

When a payload STREAM frame for pushed stream comes before the push promise, at least two problems occur.

The STREAM frame causes the on_new_stream() callback to be called. If the user calls lsquic_stream_push_info(), an assertion will fail or the program will crash because push_req is NULL:

int
lsquic_stream_push_info (const lsquic_stream_t *stream,
                          lsquic_stream_id_t *ref_stream_id, void **hset)
{
    if (lsquic_stream_is_pushed(stream))
    {
        assert(stream->push_req);
        *ref_stream_id = stream->push_req->uh_stream_id;
        *hset          = stream->push_req->uh_hset;
        return 0;
    }
    else
        return -1;
}

If the user refuses the pushed stream, the connection will abort when the push promise comes in:

    if (conn_is_stream_closed(conn, uh->uh_oth_stream_id) ||
        find_stream_by_id(conn, uh->uh_oth_stream_id))
    {
        ABORT_ERROR("invalid promised stream ID %"PRIu64" already used",
                                                        uh->uh_oth_stream_id);
        goto free_uh;
    }

What should happen is as follows. The on_new_stream callback should be delayed for pushed streams until the push promise is available. The check for used promised stream ID can be removed. (An alternative is to keep a separate list of used promised stream IDs, but that seems excessive.)

So from what it looks like the lsquic-client is using HTTP/1.1 right now (or at least the google server sends back an HTTP/1.1 answer)

Now from what I know google quic is supposed to run underneath HTTP/2 shim

Are there any plans to add HTTP/2 support to the client?

Hi, can this lib be used as a pure QUIC library? For example, implementing an echo server and client, communicating using QUIC protocol?

Looking forward for your reply. Thx!

does this lsquic readme need and update on cmake with your instructions i get BORINGSSL_DIR is not used by this project error

CMake Warning:

    BORINGSSL_DIR

without BORINGSSL_DIR i get

Handshake fails versus this public URL: https://bitdash-a.akamaihd.net/content/sintel/sintel.mpd
It seems that the client cannot decrypt the packets coming from this server.
The chromium quic client for example interops ok.

May I ask you for a hint in the next issue or maybe an advice, what can be additionally checked?

47/53 Test #47: frame_rw .........................***Failed 22.83 sec

it is a quic lib, if i want to develop a QUIC server, may I use lsquic in server?

On the FOSS server fossies.org I have used a new functionality and have done as a trial a "codespell" run for the "lsquic" project. Here the version independent URL of the resulting report:

https://fossies.org/linux/www/lsquic/codespell.html

That URL redirects always to the URL of the report for the last "lsquic" release supported on Fossies (in case such a report was requested respectively is existing). Currently that is

https://fossies.org/linux/www/lsquic-2.5.1.tar.gz/codespell.html

Although I have already prefiltered some obviously wrong matches (false positives) please inform me if you find more of them so that I can force a new improved check.

I know it's not an important issue and naturally you can ignore it.

On CentOS 7,6 64bit docker, the docker build command reports Cmake errors for Cannot find source file: ls-qpack/lsqpack.c

docker build -t lsquic .

I found build issue on linux and mac os , both are the same error.

Here is the log:

/home/zhangchi09/develop/lsquic-client/test/prog.c:19:26: fatal error: event2/event.h: No such file or directory
compilation terminated.
CMakeFiles/http_client.dir/build.make:86: recipe for target 'CMakeFiles/http_client.dir/test/prog.c.o' failed

pls help me to find out the solution , thx.

Hi,

I am trying to build lsquic-client in windows 10 64bit machine. I have all the dependencies. All the library paths in the target_link_libraries of the CMakeLists.txt is correct. However it still cannot build the lsquic.lib library in either the debug version or the optimized version. These are the errors I got in the optimized version
