Test on Boost project

[rakhimov]

The current running time with pypy:

• 3s for parsing and creating components
• ~7s to analyze and plot the graph (networkx)

SUMMARY: Components: 10254 Cycles: 1 Levels: 20 CCD: 14748 ACCD: 1.438268 NCCD: 0.116692(typical range is [0.85, 1.10])

@rakhimov Could you please provide the test setup of this run (invokation location of cppdep, file system structure, config.yml, etc.). As there is no documentation right now this would help others to understand how to use cppdep...

[rakhimov]

@fkromer This is the initial setup (used with cppdep 0.1.0).

Currently, the configuration file is under refactoring,
so the meaning of paths and setup are likely to change.
Anyhow, please feel free to contribute to the wiki of the project.

[rakhimov]

Boost source is from the archive (not the git repositories).

[fkromer]

@rakhimov Thanks. I will do so.

[fkromer]

@rakhimov I tried it with the github boost sources:

~/ws_github $ git clone https://github.com/boostorg/boost.git
...
~/ws_github $ cd boost/
~/ws_github/boost $ virtualenv -p /usr/bin/python3.4 pyvenv
...
~/ws_github/boost $ source pyvenv/bin/activate
(pyvenv) ~/ws_github/boost $ pip install cppdep
...

I added the config_boost.xml in /ws_github/cppdep (with adjusted boost src directory, c++ stl version):

<cppdep>
  <package-group name="Boost" path=".">
    <include-path/>  <!-- The project group root path -->
    <src-path>libs</src-path>
  </package-group>
  <package-group role="external" name="STD" path="/usr/include">
    <include-path/>
    <package name="STL">
      <include-path>c++/4.8</include-path>
    </package>
    <package name="BoostExternal">
      <alias-path>boost</alias-path>  <!-- The fake project to find headers -->
    </package>
  </package-group>
</cppdep>

I ran cppdep:

(pyvenv) ~/ws_github/boost $ cppdep -c ./config_boost.xml
Traceback (most recent call last):
...
File "/home/florian/ws_github/boost/pyvenv/lib/python3.4/site-packages/cppdep.py", line 358, in _update
(path, self.group.path, self.group.name))
cppdep.InvalidArgumentError: boost is not a directory in /usr/include (group STD).

Did you installed boost into /usr/include/boost as "fake project to find headers"?

[rakhimov]

Yes, the reason is #32

[fkromer]

The c++ stl and boost is expected to be installed, if not installed yet:

~/ws_github/boost $ sudo apt-get install build-essential
~/ws_github/boost $ sudo apt-get install libboost-all-dev

Now I get:

(pyvenv) ~/ws_github/boost $ cppdep -c ./config_boost.xml

I think the problem is that you are getting Boost from the git repo.
The configuration is for Boost 1.56 from the archive (distributed by release).

I think a better configuration would be to have a configuration for each sub-project within Boost
as is done for git with git submodules.

[fkromer]

Right, I give it a try...

[fkromer]

I checked out all the submodules:

~/ws_github/boost $ git submodule update --init --recursive --remote --no-fetch

But I got a lot of errors when I ran cppcheck over all of them in a single run:

TypeError: not all arguments converted during string formatting
...
Message: 'include issues: duplicate include:'
...
Message: 'include issues: include order:'
...
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf8 in position 371: invalid start byte

[rakhimov]

This 'utf-8' and other bugs have been fixed in the current development:
https://github.com/rakhimov/cppdep/milestone/2?closed=1

This is still work in progress.
I would say, for now, please wait till the configuration file stabilizes with version 0.2.0.

I hope the example configuration file and schema should be enough to grasp how to setup a project analysis.

[fkromer]

I added a separate config_boost_filesystem.xml in boost/libs/filesystem:

<cppdep>
  <package-group name="Boost filesystem" path=".">
    <include-path/>  <!-- The project group root path -->
    <src-path>src</src-path>
  </package-group>
  <package-group role="external" name="STD" path="/usr/include">
    <include-path/>
    <package name="STL">
      <include-path>c++/4.8</include-path>
    </package>
    <package name="BoostExternal">
      <alias-path>boost</alias-path>  <!-- The fake project to find headers -->
    </package>
  </package-group>
</cppdep>

I ran:

(pyvenv) ~/ws_github/boost/libs/filesystem $ cppdep -c ./config_boost_filesystem.xml

...got some warnings and errors but was able to display the diagrams (requires xdot, if not installed yet: sudo apt-get install xdot):

(pyvenv) ~/ws_github/boost/libs/filesystem $ xdot 'Boost filesystem_src.dot'
(pyvenv) ~/ws_github/boost/libs/filesystem $ xdot 'Boost filesystem.dot'
