sonar-scanner hangs with sonar-sxx 2.1 #2505

AndreyAlifanov · 2023-04-12T04:40:52Z

After update sonar-cxx from version 2.0 to 2.1 our scan hangs after 10-12 minutes of work.
I tried it with SonarQube 8.9LTS and 9.9LTS, scanner of version 4.8.0

It works with sonar.cxx.squid.disabled=true, but it's not good decision. Because we need information for code coverage, code duplications, code lines and so on.

PS With version 2.0 of sonar-cxx process works well. But this version doesn't work with SonarQube 9.9LTS, only with 8.9. :-(

Hi @AndreyAlifanov,

can you provide more input with debug info on from the LOG file please:
https://github.com/SonarOpenCommunity/sonar-cxx/wiki/Get-Debug-Information

In which step / sensor does it hang?
In case you are waiting longer, does it finish?
From your description I understand that the source code is the same?

Here scanner hangs

In which step / sensor does it hang?
We use only pvs-studio plugin to load results of static analysis for C/C++ code. All other sensors we don't use.

In case you are waiting longer, does it finish?
No, scan doesn't finish.

From your description I understand that the source code is the same?
Yes, our source code and configuration file are the same. Difference is only in sonar-cxx versions.

Regards

AndreyAlifanov · 2023-04-12T10:26:18Z

I've excluded folder with boost from list to analyze. And scanner doesn't hang.
But we should analyze boost as well as other code in our project.
So it's not a solution.

guwirth · 2023-04-13T20:09:55Z

Hi @AndreyAlifanov,

Why do you need to scan third party code?

https://github.com/SonarOpenCommunity/sonar-cxx/wiki/Detect-and-fix-parsing-errors

Hint: Since the cxx plugin only reads macros from the include files in order to parse the code syntactically in a correct way, it is often better to provide the missing macros instead of reading in all include files. Reading many include files (e.g. STL, Boost, MFC, ATL, ...) often slows down the analysis considerably. The recommendation is to include only include files for your own code.

I would recommend you to exclude all third party code
https://docs.sonarqube.org/latest/project-administration/narrowing-the-focus/

sonar.exclusions=**/ThirdProjects/**

By the way: Which Boost version are you using?

Regards,

AndreyAlifanov · 2023-04-14T03:49:28Z

Hi @guwirth,

We don't need to scan code with sonar-cxx at all. We use this plugin to import results of PVS-Studio scan only.
And we should analyze all code with SAST, including third party (except code of build tools - STL, ATL, MFC etc. boost is not a part of this tools). It's demand of our regulation authority.

I don't understand, why we don't have problems with version 2.0.7? But have them with version 2.1.0.

We use boost 1.81.

Regards

guwirth · 2023-04-14T11:00:30Z

Hi @AndreyAlifanov,

I don't understand, why we don't have problems with version 2.0.7? But have them with version 2.1.0.

There is a new SQ version, a new cxx plugin version, a new API version, a different scanner, a different Java version, … . Really difficult to say what the root cause is.

Is it possible to use the old setup with SQ 8.9 and exchange the cxx plugin only (2.0.7 to 2.1.0)?
https://github.com/SonarOpenCommunity/sonar-cxx/wiki/Compatibility-Matrix

If problem also occurs there, it’s then clear that’s an plugin issue.

I can also try to test wit Boost 1.81, but that takes some time.

One know issue is #2131.

Hi @guwirth,

as I wrote difference is only in version of plugin.
I tried version 2.1 with SonarQube 8.9 - it hangs too.

I'm really sorry, if it's not clear in my first letter.

Regards

guwirth · 2023-04-14T13:50:10Z

Hi @AndreyAlifanov,

thanks, I just wanna be one the safe side.

Looking to the log file

it’s hanging in D:\AP\ThirdProjects\boost\function_types\detail\pp_cc_loop\master.hpp.
This file has some includes were the plugin is not able to open (wrong missing sonar.cxx.includeDirectories).
After [D:\AP\ThirdProjects\boost\function_types\detail\pp_cc_loop\master.hpp:72]: preprocessor cannot find include file '# include <boost/function_types/detail/encoding/undef.hpp>' it’s hanging then.

Something special in this file? You can also try to copy/paste the content of that file into
https://github.com/SonarOpenCommunity/sonar-cxx/releases/download/cxx-2.1.0/cxx-sslr-toolkit-2.1.0.428.jar to see if it’s working/hanging.

As said above I need some more time to reproduce the setup.

Regards,

guwirth · 2023-04-14T13:55:08Z

Hi @AndreyAlifanov,

maybe easier for you is to delete all other files except D:\AP\ThirdProjects\boost\function_types\detail\pp_cc_loop\master.hpp and analyze again to see if the content of this file is the root cause.

Regards,

AndreyAlifanov · 2023-04-14T16:25:57Z

Hi @guwirth,

ok, I'll try it next week.

Hi @AndreyAlifanov,

I reduced the file \boost_1_81_0\boost\function_types\detail\pp_cc_loop\master.hpp to below which is still slow (hanging). Root cause seems to be the BOOST_PP_EXPAND(#). Replacing BOOST_PP_EXPAND(#) with # it's fast again.
