[Karmic] Qtiplot cannot initialize python scripting language

[Dmitry Tantsur]

Binary package hint: qtiplot

Valid for both official 0.9.7-1 and 0.9.7.8 from ppa.
It's said that there're mistakes in their python configuration files (see http://habrahabr.ru/blogs/open_source/62534/ [rus], fixed files: http://uploaded.ivlis.com/qti.tar_.gz).

[Scott Howard (showard314)]

Thanks for your report. If you use the fixed config files, does it fix the bug?

Could you post about this on the developer forum so we can get it fixed upstream?
http://developer.berlios.de/forum/forum.php?forum_id=19947

If your attached files work, I'll try to get them included in the version of 0.9.7.8 we're trying to get into Karmic as a Ubuntu patch.

[Scott Howard (showard314)]

I've reported the bug upstream:
https://developer.berlios.de/bugs/?func=detailbug&bug_id=16303&group_id=6626

And made a patch using the suggested files from the link above provided by Дмитрий "Divius" Танцур

Before getting this into the next version of qtiplot, could you confirm that the bug exists in the default installation and that these files fix the bug?

[Dmitry Tantsur (divius)]

Yes the bug exists in the default installation (and existed in Jaunty too) and with these files everythings works for me.

[Scott Howard (showard314)]

Upstream just said that this is not a bug and marked it as invalid. Could you please write out a test case for this bug? Can you give the exact steps you do to create the bug and the steps you do to fix the bug?

[Dmitry Tantsur (divius)]

Easily. Open qtiplot, go to menu Scripting->Scripting language, select
"Python" and watch an error message.
I'm quite surprised by your reaction, because this bug is well known
for a long time (you can translate the article above using google and
see it).

Hello everybody,

After a closer look at the problem, it looks indeed that the changes in the qtiplotrc.py file (in function "import_to_global") solve the initialization issue when running QtiPlot from a folder where you don't have write access.

I will apply the patch in my next commit to SVN.

With best regards,
Ion Vasilief

[Scott Howard (showard314)]

Ion, thanks for looking into this. Divius, thanks for reporting it.

Great! We can cherry pick this fix into Karmic once it hits the svn.

[sergio (sergio-tarsiero)]

when starting Scott's package installed from his ppa i get this error message:

"Accessing QtiPlot functions or objects from Python code won't work. Probably your version of Qt/SIP/PyQt differs from the one QtiPlot was compiled against."

i have karmic.

my system's packages:
python-pyqt 4.6-1
python-sip4 4.9.1-snapshot-20091015-0ubuntu1
libqt4 4.5.3
python2.5 2.5.4-1ubuntu6
python2.6 2.6.4-0ubuntu2

in view/preferences/file locations i verified that python directory was correctly reported as /usr/lib/python2.5 (as far as i know, qtiplot 0.9.7-8 is compiled against python 2.5) , but i can't use python, though.

[Scott Howard (showard314)]

A few days before Karmic's release the Sip package was updated. That
update broke qtiplot totally in karmic (would not compile/plot at
all). To get a working version, we had to do an stable release update
for qtiplot, which involved compiling qtiplot without python support.
Unfortunately, both the qtiplot version in Karmic and Debian Unstable
need the older version of Sip to compile with python support. The best
solution is to get the newest version of qtiplot into debian/ubuntu.
However, the newest versions ship with it's own static libraries that
are shared in ubuntu/debian, which is generally not allowed or avoided
in our distributions. Therefore, we're kind of in a cache 22: we can't
upgrade because of custom static libraries, but can't stay the same
because of updated shared libraries.

This would be fixed if someone could either 1) teach the Karmic/Lucid
version of qtiplot to use the new Sip or 2) teach qtiplot 0.9.10 to
use debian's shared libraries.

[Dmitry Tantsur (divius)]

Honestly, compiling QtiPlot is painful. I've tried but failed. Maybe
I'll try to once more.

[Scott Howard (showard314)]

The version of qtiplot in lucid works with Python scripting (0.9.7.10). However, you have to manually set the directory as seen in:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=560429
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=471709

Otherwise it will continue to fail to initialize. This bug is remaining open and has been forwarded upstream in the first above linked report.

The workaround is repeated here:
"Edit" -> "Preferences"
"File Locations"
"Python Configuration Files" is blank, it needs to be "/usr/share/qtiplot"

[sergio (sergio-tarsiero)]

I should try to install it backporting it in karmic. unfortunately i can't find any ppa for qt 4.6...

[Dmitry Tantsur (divius)]

Installed packages from Lucid. 0.9.7.10+r1453-1ubuntu1 works in Karmic after fixing preferences, thank you.

[Dmitry Tantsur (divius)]

No longer works in Lucid:
qtiplot 0.9.7.10+r1453-1ubuntu1
python-sip4 4.10.0-2ubuntu2
libqt4 4:4.6.1-1ubuntu2
python-qt4 4.7.0-2ubuntu2

It seems that qtiplot should be rebuilt against new sip.

[Dmitry Tantsur (divius)]

[Scott Howard (showard314)]

Thanks alot again, Divius

I have a rebuilt package here:
https://edge.launchpad.net/~showard314/+archive/qtiplot-ppa
ppa:showard314/qtiplot-ppa

Could you confirm that simply rebuilding the package fixes the bug?

I also can't access:
https://bugs.edge.launchpad.net/bugs/518473

what is that bug about?

[Dmitry Tantsur (divius)]

This bug is about failure, now I've made it public.

Yes, rebuilding the package fixes the bug, thank you.

[Dmitry Tantsur (divius)]

Doesn't work again:

Divius, you're saving this package in Lucid!

I have a rebuilt package here:

Could you confirm that simply rebuilding the package fixes the bug?

Make sure these two builds are complete first:

[Dmitry Tantsur (divius)]

No, version ppabuild2 doesn't work.

[Scott Howard (showard314)]

I'm classifying this bug as "fixed released" for Lucid and "won't fix" for Karmic as it will be too difficult to get SRUs for all the needed libraries in Karmic. This bug has been fixed in Lucid (you have to set the preferences yourself first, see bug #555779). Please test the Lucid version (as we'll be in Beta 2 soon) to make sure it is working properly. Thank you all for your help.

[Dmitry Tantsur (divius)]

Seems to need one more rebuild, now for Natty: see bug 735546
