python3-pyqt5.qsci not built against python3-pyqt5 on Ubuntu Utopic

[Davy39]

## Impact
Package python3-pyqt5.qsci is broken in Utopic and Vivid:

>>> import PyQt5.Qsci
python3: siplib.c:11993: sipEnumType_alloc: Assertion `(((currentType)->td_flags & 0x0007) == 0x0003)' failed.

Affects all apps depending on that package (i.e. Eric IDE).

## Test Case
Import PyQt5.Qsci module from Python 3.

## Proposed Fix
A simple rebuild fixes this.

## Regression Potential
Close to zero because it's just a rebuild.

[Scott Kitterman (kitterman)]

Please provide the SRU information described in https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template and then we'll see about a rebuild.

[Davy39 (davy39)]

[Impact]

 * An explanation of the effects of the bug on users :

Eric IDE, a pyqt5.qsci based software crash on startup

 * justification for backporting the fix to the stable release :

After rebuilding PyQt5.qsci from source, this bug disapear.

[Test Case]

 * Detailed instructions how to reproduce the bug :

# On a fresh Ubuntu Utopic 64bits installation
sudo apt-get install qt5-default qtbase5-dev qttools5-dev-tools libqt5scintilla2-11 python3-pyqt5.qtwebkit python3-pyqt5.qtsvg python3-pyqt5.qtsql python3-pyqt5.qsci
#Buid Eric IDE (for pyqt5 based app devellopement)
hg clone http://die-offenbachs.homelinux.org:48888/hg/eric
cd eric
sudo python3 install.py
#Try to run Eric6
eric6
# Getting "<class 'TypeError'>" "QsciLexerPython(QObject parent=None): argument 1 has unexpected type 'Shell'"
#More detail about this bug here : http://die-offenbachs.homelinux.org:48888/issues/msg575

 * these should allow someone who is not familiar with the affected package to reproduce the bug and verify that the updated package fixes the problem :

# By rebuilding PyQt5.qsci from sources, I get rid of this error
sudo apt-get sources python3-pyqt5.qsci
cd qscintilla2-2.8.3+dfsg/Python
python3 configure.py --pyqt=PyQt5 -q /usr/lib/x86_64-linux-gnu/qt5/bin/qmake
make
sudo make install
#Launch the same app
eric6
# -> OK

[Regression Potential]

 * discussion of how regressions are most likely to manifest as a result of this change :

I don't see any chances of regressions

[Other Info]
  Fell free to ask for more details.

[Davy39 (davy39)]

Sorry i made a mistake in previous post, the complete build instruction is (I forgot -d /usr/lib/python3/dist-packages/PyQt5) :

#Build PyQt5.qsci from sources
sudo apt-get sources python3-pyqt5.qsci
cd qscintilla2-2.8.3+dfsg/Python
python3 configure.py --pyqt=PyQt5 -q /usr/lib/x86_64-linux-gnu/qt5/bin/qmake -d /usr/lib/python3/dist-packages/PyQt5
make
sudo make install

[Dominique Cyprès (lunasspecto)]

I am having some trouble with the workaround provided by davy39 in Comment #2 and Comment #3. I followed the suggested steps, with a small substitution for the i386 platform, so the command I used to invoke the configure script was this:

python3 configure.py --pyqt=PyQt5 -q /usr/lib/i386-linux-gnu/qt5/bin/qmake -d /usr/lib/python3/dist-packages/PyQt5

The Pyqt5.Qsci configuration script failed with the following output:

Configuring QScintilla 2.8.3...
QScintilla None is being used.
The QScintilla .sip files will be installed in /usr/share/sip/PyQt5.

[Gustavo A. Díaz (gdiaz)]

Dominique: thats cause you need to have pyqt5-dev installed.

[Gustavo A. Díaz (gdiaz)]

After compile Pyqt5.Qsci from source (as Davy39 suggested) still I can't run Eric IDE (v6):

[Dominique Cyprès (lunasspecto)]

In response to gdiaz in Comment #5: the output I provided in Comment #4 is from a system that does have pyqt5-dev installed.

[KaIkuN (kaktus-w-h)]

Hey, I had the same error like Dominique in comment #4 when I try to install Davy's way.

(sudo python3 configure.py --pyqt=PyQt5 -q /usr/lib/x86_64-linux-gnu/qt5/bin/qmake --qsci-incdir /home/kaikun/Eric_Python_IDE/QScintilla-gpl-2.8.4/Qt4Qt5/ -d /usr/lib/python3/dist-packages/PyQt5)

when I removed python3-pyqt5.qsci , pyqt5-dev was removed as well so I reinstalled it.
Now I get an error in the next step, doing make:

g++ -c -m64 -pipe -fno-exceptions -O2 -Wall -W -D_REENTRANT -fPIC -DSIP_PROTECTED_IS_PUBLIC -Dprotected=public -DQT_NO_DEBUG -DQT_PLUGIN -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/lib/x86_64-linux-gnu/qt5/mkspecs/linux-g++-64 -I. -I../Qt4Qt5 -isystem /usr/include/python3.4m -isystem /usr/include/x86_64-linux-gnu/qt5 -isystem /usr/include/x86_64-linux-gnu/qt5/QtGui -isystem /usr/include/x86_64-linux-gnu/qt5/QtCore -I. -o sipQsciQsciLexerBash.o sipQsciQsciLexerBash.cpp

I dont know just trying to install eric6 since two days, first got the error in #6 so I try dave's way now.

[bertuzzi.claudio (bertuzzi-claudio)]

I also have this bug (or similar) in new FRESH INSTALL kubuntu 15.04. (I've only added leafpad and aptitude)

To produce this bug:

install new kubuntu 15.04 (probably all ???buntu 15.04)
sudo apt-get update
sudo apt-get dist-upgrade

#now install python3-pyqt5.qsci
sudo apt-get python3-pyqt5.qsci

#open python3 consolle and "from PyQt5 import Qsci" The result is:

[Gustavo A. Díaz (gdiaz)]

Same for me, I just (for now) ended installing Qt (with their own
installer) and compilled PyQt, SIP and QScintilla by hand and works
perfectly.

Cheers.

For Wily this will be fixed via a Debian upload, which will also add an autopkgtest to catch such issues.

[Scott Kitterman (kitterman)]

Hello Davy39, or anyone else affected,

Accepted into vivid-proposed. The package will build now and be available in a few hours in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[bertuzzi.claudio (bertuzzi-claudio)]

thank's! Work for me :-)

I've tested (for now in a UNclean 15.04 ubuntu PC sorry).
I've enable proposed following the example of the page you suggested
sudo apt-get update
sudo apt-get install python3-pyqt5.qsci/vivid-proposed

and now this command:

python3 -c "from PyQt5 import Qsci"

work with non crash
Also eric6 work! Thank's a lot!

This evening I will install a new machine and try this "proposed" on a clean install

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[juanjux (juanjux)]

I was having the same problem, the proposed update fixed the problem for me too on two computers and a VM.
