Build / install issue

[benbenz]

Hello,

Thanks for making this repository!

I'm having trouble installing/running the repository. When following the install directions (v1), it seems git is not finding a valid git repository. When trying to install after downloading the repository (v2), the submodules are properly installed but the build is failing because build.ninja is missing ... ? I know I do not have perl6 installed yet but it doesn't seem to be related to this quite yet and I wanted to try with the default perl for now...

OS: Mac OSX 10.13.6 (High Sierra) Node: Node v16.14.0 NPM: v8.3.1 protoc: libprotoc 3.19.4 ninja: 1.10.2 Go: go1.17.8 darwin/amd64 cmake-js: 6.3.0 cmake: 3.23.0-rc2 clang: Apple LLVM version 10.0.0 (clang-1000.11.45.2) perl: v5.18.2

Hi, thanks for the analysis. I am sorry but I am still struggling, how to incorporate the git submodules in npm for the different libraries correctly. After looking into the npm install docs, it seems to be necessary to use: npm install --save git+https://github.com/fails-components/webtransport for the installation, since this should should also fetch the submodules. (I do not have a unix cmd at hand, it still fails under windows, but would be nice if you can try it and post the error log). This was for v1.

For v2, please do instead:

cd webtransport
git submodule update -i -r
npm run install

I have no removed the git submodule update, since it did not work in v1. But I am puzzled about the message, that it does not find build.ninja. Since this should be generated by cmake.js in build/build.ninja, can you check this and the content of the build directory?

[martenrichter]

Ok v1 is still broken, it seems, that npm strips the whole .git stuff before installing, in this way also the submodules are gone..., this need some additional work.

Hi,

No worries!

v1

With the new URL, it seems it goes further, but stops when it compiles the webtransport project:

Thank you for your help!

[martenrichter]

With v1 it is puzzling. The problem is that the libs are git submodules. The new npm command should also fetch the submodules, but for some reasons CMake say the diretories of the three submodulesthird_party/abseil-cpp,third_party/boringssl/srcandthird_party/zlib` are empty. While trying to debug, I believe I had it once that it worked today, I will try to find the right commit hash (but I may be mistaken). npm should have handled the submodules, I can not do anything, since the git stuff is already gone in the preinstall script.

For v2, you are right npm run install is wrong npm install is right. Here is my build directory: But I think in CMakeError.log is the clue:

Change Dir: /Users/benoit/dev/webtransport/build/CMakeFiles/CMakeTmp ```

I can only guess that one of the libraries contain a test for off64_t type and it is not present on Mac OS X. But I have also no clue, which lib and which its cmake file it is. You can google about this error I found for example also OpenCV with this issue... and some google products long time ago....

Any way if it does not help, you may consider running it in a docker linux container as I do it under windows, I assume that the application is finally running under linux anyway.

[martenrichter]

Ok regarding v1, there seems to be a problem in npm since version 7 (https://github.com/npm/cli/issues/2774) that breaks submodule support in npm. Maybe you can revert back to npm 6, or pursue v2 further. I have to think, if I start releasing prerelease packages, but actually I do not like this as long as the packages is not really tested. Regarding v2, you may look into the CMakelists.txt file, there you may want to comment add_subdirectory and see if the error concernung off64_t goes away, if any of them is excluded. Of course other errors will pop up, but in this way we can identify if any of these libs causes CMake to do this test. Protobuf may be another cause.

[benbenz]

hi again,

v2 seems to work a little further .... but the main problem is the code relies on the epoll implementation in quiche which is not supported in OSX :( The dockerization of the server could be an option indeed! But I have a pretty tight session interaction with an existing server that I need to maintain.

"Working" steps:

git clone --recurse-submodules https://github.com/fails-components/webtransport.git
cd webtransport
npm install # this will throw an error but it will install the node_modules
cmake-js compile 

cmake-js compilewill throw errors on all epoll related stuff... (noticeably sys/epoll.h not found). Ex:

/Users/benoit/dev/webtransport/third_party/quiche/epoll_server/simple_epoll_server.h:38:10: fatal error: 'sys/epoll.h' file not found
#include <sys/epoll.h>
         ^~~~~~~~~~~~~

It is possible to comment the simple_epoll_server out of the CMakeList.txt file. But the http3Server seems to be deeply rooted in EPoll.

Note1

I had to use clang v13 to avoid some compilation errors with quiche (I used the v13.0.1 binary distribution for OSX on llvm website). The flag CXXFLAGS="--std=c++17" fixed some issues but others remained.

Note2

I havent seen the off64_t error again but will look into your comments if this happens again.

Thanks again for your help !

Ok, and epoll is not available on OS X? Then there is probably not an easy way to fix this, of course, one could try to write and replacement (kqueue) , if a similar mechanism exists, so something that wakes up, if some thing happens to a fd. But for me without a mac, it has zero priority. And it probably needs some time. And the tight session interaction does this mean your server is on OS X...? I thought most server will eventually run on linux.

"Working" steps:

git clone --recurse-submodules https://github.com/fails-components/webtransport.git
cd webtransport
npm install # this will throw an error but it will install the node_modules

         ^~~~~~~~~~~~~

It is possible to comment the simple_epoll_server out of the CMakeList.txt file. But the http3Server seems to be deeply rooted in EPoll.

Yes the whole architecture of libquiche seems to be event driven by the epollserver, but of course it should be possible to be replaced.

that means set(CXX_STANDARD 17) in cmakelists.txt does not set it to c++17 ?

Note2

I havent seen the off64_t error again but will look into your comments if this happens again.

Thanks again for your help !

[benbenz]

Hi,

Understood :) I forked the project and will try to adapt the server to libuv, libev or kQueue. I've read Nodejs is using libuv? It would be logical to stay with this maybe? I don't have any experience with this but I will let you know if I finished something that is somewhat running....

Thanks again !

[benbenz]

Hmm it could have been that I ran sequential compiles and the first errors were skipped, only to come back again at the "end". I would have to look more into this.... I could be wrong.

I do not think that you have to do so much changes. Please look into: https://github.com/fails-components/webtransport/blob/master/platform/net/quic/platform/impl/quic_epoll_impl.h Here you can insert some preprocessor stuff to branch to other epoll objects for MacOS. These object you can then also place in the platform impl dirs of the package. I think can just copy the epoll server code from libquiche and change the few system calls to kqueue, rename it and that's it. (If it is compatible...) Then some changes to the cmakefile... and that's it. I do not think there are many other platform dependent things lurking, most is STL. Edit: I just saw that libuv is using epoll and kqueue in the background, so yes an epoll server with libuv would be great, the file where the changes happen remain the same....

Hopefully yes ! Thank you for the pointer. I'm having a little bit of an issue with the compilation of quiche at the moment but if that is solved, I hope to be able to adapt to a libuv implementation.

Note: I understood the reason for the build.ninja not found error: when the configure script errors before starting to compile the files, on the next run, it will try to go to the next step and not find the build.ninja file. You have to remove the build directory (after solving the original issue) so that it builds properly.

[benbenz]

that means set(CXX_STANDARD 17) in cmakelists.txt does not set it to c++17 ?

So it seems the flag was not taken into account on Mac. I had to add this line in CMakeList.txt:

set_property(TARGET gquiche PROPERTY CXX_STANDARD 17)

Great. Glad I could help. I've actually added to the webtransport project/target as well.

Ok, I have added this as well.

[benbenz]

Hi ! I think the code is working on Mac OSX. There were some small issues with the CMake file on mac (some even dependent on the cmake version) and needing some rewriting of the simple_server with libuv. But I think I am seeing the right messages here on Chrome. It also works "as this" with no special options and certbot certificates. Let me know if you want me to detail here the main changes? Again, thanks so much for this work and your contribution !!

[martenrichter]

Hi! Thanks, I have used your code as inspiration for replacing the epoll server entirely with libuv (actually you do not have to build it, it is readily available for a node c++ addon). The corresponding commit is https://github.com/fails-components/webtransport/commit/52a462c473f11f1f6a8c7dd151911038d55fac16 .

I tried to find all changes, I hope I did not miss any. But in the CMake file I left out: ``` target_include_directories(gquiche PUBLIC /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk /usr/local/include) # on older CMake -isysroot removes /usr/local/include ```` I think this was debugging code. Please tell me if I missed something.

[benbenz]

Hello. Great, thank you. Looking at the changes I think this looks great.

CMake:

• I will try again without the SDK path but I remember I had an error at some point which pushed me to include this. But I havent tried again without and it could have been related to something else. I will let you know.
• Same for the /usr/local/include. On another machine I had to include this because clang (or maybe CMake) was removing this directory silently when the -isysroot option was activated. It wouldn't hurt to leave this here anyhow.

One thing though: it would be nice to add the libuv submodule. I have now installed libuv on my mac but I know it was not there before, so it would be nice to add this submodule as well, dont you think? This would avoid an extra step of installation for people checking out the repository. Is it always installed on Linux?

I will give a fresh install a try shortly and let you know.

[martenrichter]

Hi,

CMake:

• I will try again without the SDK path but I remember I had an error at some point which pushed me to include this. But I havent tried again without and it could have been related to something else. I will let you know.

But anyway, if it is needed, hard coding the path is not an option, since it may change. So if it is missing, a CMake variable or mechnaism, that will determine the path should be used, otherwise it will break if the path changes or is different for different versions.

• Same for the /usr/local/include. On another machine I had to include this because clang (or maybe CMake) was removing this directory silently when the -isysroot option was activated. It wouldn't hurt to leave this here anyhow.

Here it is the same, we have to use a mechanism, which adds the missing part of the object automatically during configure, similar to the stuff for example for protobuf.

One thing though: it would be nice to add the libuv submodule. I have now installed libuv on my mac but I know it was not there before, so it would be nice to add this submodule as well, dont you think? This would avoid an extra step of installation for people checking out the repository. Is it always installed on Linux?

No it is not always there for linux. But it is an integral part of node itself (and is also used by nan internally) and it is important to use the same lib in this case (for the other libs in the submodules it is important, that we use a different http3 capable version), so that not problems with mixing two libs occurs. But I had to add:

 target_include_directories(gquiche
....
PUBLIC ${CMAKE_JS_INC}
)

so that all parts used for nan (and libuv is one of them) are already present when building lib quiche.

[benbenz]

Nice! 👯‍♂️ I will clone and report asap

[benbenz]

Hello! I tried a fresh build and I encountered just one issue with the protobuf library not found. This was related to the /usr/local/include directory being added to the gquiche library.

This fixed the problem, around line 807 in CMakeLists.txt:

        target_include_directories(gquiche PUBLIC /usr/local/include)
        target_link_directories(gquiche PUBLIC /usr/local/lib) 

While investigating I found out that the -isysroot option added by CMake on OSX may disable the lookout for this directory: here I think there is a fix with that NLOPT_INCLUDE_DIR thing, but it seemed okay to add those directories as they are pretty much created on any OSX distribution and this is the default path where protobuf installs when running a make install But I agree its not very clean :/

Other than that, the test ran without any issue once this modification was brought to CMakeLists :)

[benbenz]

Actually, I realize CMakeLists.txt has a section to find the Protobuf install. It should be possible to re-use ${Protobuf_LIBRARIES}and ${Protobuf_INCLUDE_DIRS}: here

This seems to work: line 22:

set(Protobuf_USE_STATIC_LIBS ON)

~line 795:

target_link_libraries(gquiche 
absl::base 
absl::int128
absl::strings 
absl::str_format
absl::flat_hash_map
absl::any 
absl::synchronization 
${Protobuf_LIBRARIES}
ssl crypto)

if(APPLE)
        target_compile_definitions (gquiche PRIVATE __APPLE_USE_RFC_3542)
        target_include_directories(gquiche PUBLIC ${Protobuf_INCLUDE_DIRS})
endif()

The reason why I added set(Protobuf_USE_STATIC_LIBS ON)is because the test was hanging mid-way without it. I suspect the Apple Security stuff to lock the dependent protobuf DYLIB. But it was not showing it for some reason. Using the option made the test run entirely.

EDIT: still seems to be hanging sometimes.

[benbenz]

This becomes unrelated to this thread but, are you seeing some of the following issues? 1) sometimes the test is not completing properly: it hangs at the datagram stage (I realized this could be the case after some refreshes in the forked version as well) 2) segfault on a hard refresh from the client side (Chrome) (not happening on the forked version) 3) TypeError: this.streams.delete is not a functionerror on webtransport.js:238 (not happening on forked version)

[martenrichter]

This becomes unrelated to this thread but, are you seeing some of the following issues?

1. sometimes the test is not completing properly: it hangs at the datagram stage (I realized this could be the case after some refreshes in the forked version as well)

I did not see this, or I did not pay attention. I will have a lock at the weekend.

2. segfault on a hard refresh from the client side (Chrome) (not happening on the forked version)

I have seen this as well, but not after I made some additional changes/fixes, however I forget to push. I will look in the evening or tomorrow morning to push it.

3. `TypeError: this.streams.delete is not a function`error on `webtransport.js:238` (not happening on forked version)

Yes, I found this and fixed it, but I forgot to push. (Hopefully this is the reason...)

[martenrichter]

Now, the forgotten fixes are commited and pushed. Hopefully this fixes the segfault. But anyway there might be still issues related to garbage collection and object deletion. So if anything odd happens please post it.

[martenrichter]

EDIT: still seems to be hanging sometimes.

I have added these chnages as well. Static linking is fine, in this way binaries will also work on systems with out protobuf installed, which may be beneficial. I think no we got the mac os x case.

[benbenz]

Hi I ran a fresh clone. Everything built as expected and the test ran fully! Closing the issue. I noticed some hangs on some refreshes with Chrome, but no segfault, no webtransport.js error and some of the next refreshes could recover fully.

[martenrichter]

I noticed some hangs on some refreshes with Chrome, but no segfault, no webtransport.js error and some of the next refreshes could recover fully.

One final note, this was probably caused by faulty example code for the client side, if buffers got merged, which is allowed according to spec. This is now fixed.

[benbenz]

Oh that's great ! Thanks. I should start with webtransport next week. I'll make sure to let you know if I notice anything.

[benbenz]

Test is working consistently on osx as well :)

[martenrichter]

I know the issue is closed, but library quiche changed the eventloop default implementation, which should now cover mac os x as well. Would you test the following branch on mac os x before I merge it with master: https://github.com/fails-components/webtransport/tree/eventloop ? Thanks!

[benbenz]

No problem: will check the branch today or tomorrow and let you know.

[benbenz]

I tried with the eventloop branch and I get a handshake error in the browser. I dont see any error on the server side. Also, I don't get this error with the master branch.

Connection failed. WebTransportError: Opening handshake failed.
Connection closed abruptly 

I tried running Chrome with the "ignore errors" options, without luck (it seems the ignore-certificate-errors-spki-list argument is not recognized by chrome v102 though). I have been using a certbot certificate which has been working fine so far (and still works in the master branch).

I guess there is an event sequence that is not fully completed while negotiating? Any idea where I should add breakpoints to figure this out?

[martenrichter]

Well, opening handshake is probably just a sign, that the event loop got stuck. There is in terms of certifcates no difference between the branches. You can also run npm test and see if this is working. Regarding the break points in httpeventloop.h the WakeUpHelper's ReadPipeCallback' OnSocketEvent, has a read and it can be an issue, if the read is blocking and the setNonBlocking did work on Mac.... Otherwise the OnSocketEvent of server and client can be a good place... and of course the eventloop object of the libary.

[benbenz]

Ok. I'll try to check those breakpoints out. test is giving the following output:

start generating self signed certificate
start Http3Server and startup echo tests
start GlobalEventLoop
createGlobalEventLoop
server started now wait 2 seconds
now startup client
wait for client to be ready
tests took too long, probably hanging

This means it is hanging in the polling, so I suspect really that the unblocking of the fd is not working on mac...

[benbenz]

Still trying to investigate on this ... Im having trouble breaking on the breakpoints above but I am also encountering an issue with my app. Will report as soon as this is figured out.

[martenrichter]

Maybe use a printf....., also yesterday someone suggested me, that may be other portable libs are also an option.

[benbenz]

Yes will do that. You mean for Quiche ? or libuv equivalent? So quiche has definitively moved to this new eventloop paradigm?

[martenrichter]

A libuv equivalent, quiche is currently moving towards multiple options for eventloop, there is also an option without additional event loop. I got the info yesterday not sure, what I will do.

[benbenz]

Ha Great. A lot of action seems to be going on around this event mechanism! Great to know Quiche is offering options.

hi Marten, Im coming back with not much more info sadly. Ive added printf's where they belong, at:

printf("Http3Server::CreateUDPSocketAndListen") ;
printf("Http3Server::startServerInt") ;
printf("Http3Server::OnSocketEvent") ;
printf("WakeUpHelper::OnSocketEvent\n");

Nothing prints. I've also added breakpoints there and it is not passing through. Could there be some syntax that changed (in WebTransport) in the JS and the client is disconnecting... ? I can only break in the creation of the Http3Server (ran 2 times likely because of the 2 channels in my app).

When in VS Code in debug mode, I get an ECONNRESET Error printed (sometimes a variant is 'socket hang'). But I dont get it when running the same code through the command line. This inconsistence is also a little weird to me - it could have to do with my app. I couldn't find the text that outputs this message either. The server is running very slow on this machine in debug mode, and it could timeout .. maybe. But I thought I should also mention this.

Would you have another entry point I could check ? I would have thought that startServerInt or createUDPSocketAndListen would do it !

[martenrichter]

Hi, ok interesting... different to what I thought..

hi Marten, Im coming back with not much more info sadly. Ive added printf's where they belong, at:

printf("Http3Server::CreateUDPSocketAndListen") ;
printf("Http3Server::startServerInt") ;
That is really weird, if you do not reach this point nothing can start.
Please check, 
Wake() on the Eventloop and also if Schedule is called from the event loop.
These trigger the execution of the other tasks, which are not called.
And may be also the creating of the pipe, if anything fails there.

printf("Http3Server::OnSocketEvent") ;
printf("WakeUpHelper::OnSocketEvent\n");

Nothing prints. I've also added breakpoints there and it is not passing through. Could there be some syntax that changed (in WebTransport) in the JS and the client is disconnecting... ? I can only break in the creation of the Http3Server (ran 2 times likely because of the 2 channels in my app). No, this is identical to the main branch, it must be the event.

You are right, these should do, so scheduling this task is somewhat broken. Anyway if it turns out to be too complicated, we might also wait for quiche to use different mechanism and I rewrite it again.

Ok, quiche has now a libevent based eventloop, I have switched to the new code in the branch: https://github.com/fails-components/webtransport/tree/eventloop can you test it on MacOS, please ?

[martenrichter]

Also a test on the windows branch (Windows support is almost there...) of a MacOS build would be nice: https://github.com/fails-components/webtransport/tree/windows I had to reorganize large parts of the CMakefile and include more libs.....

[benbenz]

Hello, Will test both branch and let you know !

[benbenz]

For libevent, after installing openssl (with conda in an openssl env) and running export OPENSSL_ROOT_DIR=/Users/benoit/opt/miniconda3/envs/openssl, I could build the branch. But I got this error:

[ 65%] Building CXX object CMakeFiles/gquiche.dir/third_party/quiche/quiche/quic/bindings/quic_libevent.cc.o

         ^~~~~~~~~~~~~~~~

I guess Quiche is not finding libevent ... I'm not ultra familiar with Bazel. Do you know where/how I can add the libevent dependency for quiche?

EDIT Nevermind, I forgot quiche standard build was bypassed through CMake. I have added PUBLIC third_party/libevent/include line 807 of CMakeLists.txt and this did the trick.

I then had to run the following in thirdparty/libevent, in order to create the event2/include/event-config.h file which was missing and causing another build error:

autoconf
./configure
make

I also had to add the following line in CMakeList around line 807:

PUBLIC third_party

This is not really correct/conventional, but this avoided this error:

Quiche was able to build at this point. And the TEST SEEMS TO BE OKAY ! :D :D

[martenrichter]

Yes, it is not finding the headers.... My guess is that you did not fetch the submodules with git submodule update --recursive (maybe also with --init) and that the submodule with libevent is not present. (For the windows build I had to turn some additional dependencies into submodules (not available with the needed runtime library), which increases build time on linux)...
