Python 3 support

Postby AndreasH » 14. Jul 2017, 11:48

Hello,

can somebody tell me about the status of Python3 support for the XPCOM bindings?

The SDK installer installs a vboxapi module in /usr/lib/python3.5/dist-packages, but it doesn't work. Apparently there is no compatible VBoxPython:

    import xpcom.vboxxpcom
  File "/opt/VirtualBox/sdk/bindings/xpcom/python/xpcom/vboxxpcom.py", line 78, in <module>
    raise Exception('Cannot find VBoxPython module (tried: %s)' % (', '.join(_asVBoxPythons),))
Exception: Cannot find VBoxPython module (tried: VBoxPython3_5m, VBoxPython3m, VBoxPython)


I am using Debian 9 with the packaged Python 3.5. I tried both with the pre-built VirtualBox package for Debian 9 as well as the "manual" installer.

I got confirmation that the problem is at SDK build time, so nothing on your end. It is indeed broken...

Python 3 support is definitely working since the release of 5.1 at least. What you're running into is clearly a hiccup with package building on the Oracle side. For some reason the current packages for Debian 9 (Stretch) contain only the library for Python 2.7. Looking into it, probably will be fixed with the next maintenance release.

Ouch. I ran into a whole series of brick walls trying to cure this issue. The current state (not publicly available anywhere) is that installing vbox would also unconditionally install python 3.5 since the debian packaging tools are "too clever" and create dependencies, because they find the .so files which use the python library.

So far this is still unresolved. Really annoying when packaging is getting in the way of actually shipping functionality which would be long there...

Oh, and while the distro-independent .run installer wouldn't have such issues, it's highly unlikely that it could deliver working Python 3 support, since it's built on an old distro which (if at all) would have some Python version (e.g. 3.1) which you don't have.

BTW, this has absolutely nothing to do with the VirtualBox SDK. The Python support is part of the base package, covering only the system default python version. This limitation is a surprise for me, because it effectively nullifies all the work which went into the Python 3 support. One could build a VirtualBox package which supports Python 3, but only by pretending at build time that Python 3 is the system default python version. And that's really not how it should be. Rebuilding VirtualBox with weird hacks just to get Python 3 support isn't intentional.

First of all, thanks for taking the time to try and resolve this issue.

I am developing for Debian and understand the packaging system quite well. Actually, I see nothing wrong in that behaviour, at least it fits with the rest of the Debian system. What would be necessary is to split up the whole thing into multiple packages, one main virtualbox package without any python library and a "Recommends: virtualbox-python-support | virtualbox-python3-support", and two separate packages with python 2 and 3 libraries respectively.

If I could get my hands at something like a debianized source package, I might be able to help with this.

Oh, and while the distro-independent .run installer wouldn't have such issues, it's highly unlikely that it could deliver working Python 3 support, since it's built on an old distro which (if at all) would have some Python version (e.g. 3.1) which you don't have.


I already tried that, indeed it doesn't have any working Python 3 support.

Thanks for the offer to help... the VirtualBox source tarball is "debianized" out of the box. See the debian directory. If you dig around then you'll notice that it builds with VBOX_WITH_MULTIVERSION_PYTHON= (i.e. disables it). Oh, and debian/rules it's actually broken (only calls python without any script - check src/VBox/Installer/linux/debian/rules how to actually install the VirtualBox API support using vboxapisetup.py, which "only" needs to be run by the python version you want it installed for).

However, we're seriously allergic against package splitting... so far we resisted all good advice to split it in any way. Others (e.g. the official debian package) can do what they like, but for us every additional file is adding effort.

From what I read so far, it should be possible to change the behaviour of automatic dependencies by adding '--exclude=VBoxPython' to dh_makeshlibs and dh_shlibdeps in debian/rules.

I tried it myself, but didn't get far. The source one can download from https://www.virtualbox.org/wiki/Downloads or the code repository linked from that page can't possibly be the one the Debian packages for Debian 9 are generated from. The debian/ directory has multiple issues:
    * The debhelper compatibility level specified in debian/compat and debian/rules (Level 4) is not supported anymore. Minimum supported but deprecated is 5, I would suggest at least 9 to stay compatible with Debian wheezy
    * The build dependencies listed in debian/control are way out-of-date.
      they list qt4 while VirtualBox 5.1 requires Qt5. I replaced with qtbase5-dev and libqt5opengl5-dev. libqt5x11extras5-dev and qttools5-dev-tools are also required
      java-2-runtime and openjdk-6 is listed which should probably be default-jre resp. default-jdk
      libxinerama-dev, libdevmapper-dev, libvpx-dev, texlive-latex-base and genisoimage are missing
      libcurl-dev is not available anymore, I chose libcurl4-gnutls-dev instead
      ia32libs is not available anymore, we need to specify the exact needed libraries for i386 architecture

I tried fixing all of the above except for the ia32libs and started building, but it stopped with

We definitely do use the stuff from src/VBox/Installer/linux/debian for building packages. The toplevel debian directory is intentionally somewhat different (catering for differences between our build env and what we expect "normal" people to have), but the aim is to have them reasonably similar. Could be bit rot in toplevel debian...

The deb build is broken as you see but you can build the *.run version.
    <Snip from rules>
    # for some reason, the Qt libraries couldn't be found on newer releases (e.g. Ubuntu hardy)
    LD_LIBRARY_PATH=$(prefix)/usr/lib/virtualbox dh_shlibdeps
    </Snip>

Dependencies below are what should allow you to build.

Thanks for pointing this out. This directory is indeed very similar to the toplevel debian. But the build dependencies in debian/control are definitely not satisfiable with Debian 9, e.g. a package 'linux-headers-generic' has never existed in Debian 7, 8 or 9. This is an Ubuntu package. Additionally, there is still libqt4 given as build dependency, while it's clear that VirtualBox 5.1 needs Qt5. Maybe your build environment contains what is really needed to build, but then it's not completely specified in debian/control and therefore hard to recreate.

If you have a build environment where you can successfully build a package for Debian 9, I'd be interested in the output of 'dpkg-query -l'.

I will now try to install the deps from the thread linked in Perryg's Post, which is right now downloading another 2.3G of packages :shock:

I think I finally got some things sorted out:

1. The top-level debian directory is indeed bit-rotten. The rules from src/VBox/Installer/linux/debian/rules work, but only if run from that directory (some paths are hard-coded). So this package cannot be built with dpkg-buildpackage, which in turn means that the dependencies from debian/control never get checked. Instead you have to manually take care that you have all dependencies and run 'debian/rules binary' from the 'src/VBox/Installer/linux' directory. By merging the deps which I found out myself, from PerryG and the official debian package of virtualbox, I ended up with a control file that contains the right dependencies. The top-level debian directory should be removed since it is useless, IMHO.

2. Managing the python module and dependencies works as I assumed. I attached a patch that will make the rules build and install modules for both python 2 and 3, while *not* creating a dependency on python 2 or 3. It will likely need some modification to also work on systems with Python 3 earlier than 3.5, but I cannot do that at this time. Minor glitch is that the vboxapi modules get placed in /usr/local/lib/pythonX/dist-packages instead of /usr/lib/..., but that's not important.

3. For the python 3 module to work, you need my patch from https://www.virtualbox.org/ticket/16899 as well

The toplevel debian directory shouldn't be removed, it should be turned into one which directly works again.

While I can not speak of how to do this with "the debian way", I do know that the official way to build the package is to do so using the VirtualBox build process and not the hosts.

Example: running the following
Code: Select all   Expand viewCollapse view
/trunk/src/VBox/Installer/debian/rules binary

To clean if you need to rebuild:
Code: Select all   Expand viewCollapse view
/trunk/src/VBox/Installer/debian/rules clean
