TortoiseHg doesn't start

[Geier]

[Impact]
The Tortoise HG application doesn't start in raring ringtail (13.04). This is due to wrong version comparison where Qt 4.10 (included in Raring) appeared < Qt 4.6 required by the package. TortoiseHG 2.8 includes the fix.

[Test Case]
Execute command `thg`.
Expected: Application "TortoiseHG Workbench" starts
What happens: Nothing.

There are no errors in the console window, the application just stops.

$ apt-cache policy tortoisehg
tortoisehg:
  Installiert: 2.4-2
  Installationskandidat: 2.4-2
  Versionstabelle:
 *** 2.4-2 0
        500 http://de.archive.ubuntu.com/ubuntu/ raring/universe amd64 Packages
        100 /var/lib/dpkg/status

[Regression Potential]
Because 2.4-2 never worked in Raring, there is no regression in this version. Regarding changes from previous Ubuntu release, this version of application is more stable and mature release, which is also suits best the version of Mercurial shipped with Ubuntu.

Same here. Ubuntu 12.10 upgraded to 13.04 beta.

Also tried more recent mercurial / thg from https://launchpad.net/~tortoisehg-ppa, didn't make any difference.

Curiously enough, commands that don't launch a GUI -- "thg version", "thg help" -- work fine. Trying to launch the GUI fails.

Attaching the output of "strace thg" and "python -v /usr/bin/thg", hoping it might be useful.

[Kostya Vasilyev (kmansoft)]

Diagnosed the issue:

Caused by a dependency check for Qt 4.6 and PyQt 4.7 in tortoisehg/hgqt/qtlib.py.

if PYQT_VERSION_STR.split('.') < ['4', '7'] or \
   QT_VERSION_STR.split('.') < ['4', '6']:
    sys.stderr.write('TortoiseHg requires Qt 4.6 and PyQt 4.7\n')
    sys.stderr.write('You have Qt %s and PyQt %s\n' %
                     (QT_VERSION_STR, PYQT_VERSION_STR))
    sys.exit()

The "sys.stderr.write" lines above don't produce any output even when running from the command line... (?)

Upstream issue: https://bitbucket.org/tortoisehg/thg/issue/2467

[Halverneus (halverneus)]

I can confirm kmansoft's diagnosis:

In /usr/lib/python2.7/dist-packages/tortoisehg/hgqt/
I renamed qtlib.pyc -> qtlib.pyc.backup
I backed up qtlib.py -> qtlib.py.backup
I commented out lines 27-32 and was able to start and use TortoiseHg normally.

(Not the recommended fix, but it served my immediate needs.)
Thank you, kmansoft!

Running Kubuntu 13.04 Beta 1 with updates current as of 20MAR2013 inside VirtualBox.

Great, this official patch solves the issue https://bitbucket.org/tortoisehg/thg/commits/e571f9b3eadc

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

[Airlangga Cahya Utama (airlangga.cahya)]

Upstream tortoisehg already fixed at version 2.7.2 https://bitbucket.org/tortoisehg/thg/wiki/ReleaseNotes#!bug-fixes
Raring version of tortoisehg is non usable at all....

[Kostya Vasilyev (kmansoft)]

FWIW -- I've been running TortoiseHG and Mercurial from these PPAs, they need to be installed together (thg requires a certain range of hg verisons)...

There are no "raring" versions, but the ones for "quantal" have been working just fine for me.
