Refuses to launch on wxPython 3.0

[RavenB]

refuses to launch on fedora 22 claiming wxpythion 2.8 is needed while latest wxpython is installed.

[pypingou]

/cc

[uggla]

This is because Fedora 22 comes with wxpython 3.0.2 and metamorphose is looking strictly at 2.8.
By the way PIL seems not anymore available on Fedora 22, replaced by Pillow but it looks compatible.

I forced the usage of wxpython to 3.0.2 by modifying the required script.
The application starts and requests the language configuration. (removed ~/.metamorphose2)
Then a dialogbox appears with a message "Please take a moment to set your preferences.
". I click "OK".
And the application fails with this :
[uggla@ugglalaptop metamorphose2]$ ./metamorphose2 -d

Is wxPython 2.8 not available in Fedora 22?
On Ubuntu I have 2.8 and 3.0, and I admit not having tried running under 3.0.

[uggla]

Hello @ianare,

Yes Fedora 22 is shipped only with 3.0.2. It was part of the main changes :
https://fedoraproject.org/wiki/Releases/22/ChangeSet#wxPython_3
Fedora is bleeding edge this is cool, but sometimes it causes some compatibility issues.
That's a pity because metamorphose2 is a really powerful program that I used to do some mass renaming.

I tried to investigate a bit more on the issue but I was unable to get the main window working.
I'm lacking too much knowledge on wxpython and metamorphose2 internals to make it working.
If you could upgrade metamorphose2 to have it running with wxpython 3.0.2 even if it is in a bad shape, then maybe I could help correcting some issues.

[ianare]

I've added a new release 0.8.4 which allows specifying the wxPython version:

./metamorphose2 -w 3.0

I was able to get it running on wxPython 3.0.0.0 on Mint 17 (Ubuntu 14.04 LTS), although not everything worked - preferences menu for example did not show up.

I will try with a newer version of wx and see if it crashes.

[ianare]

Sorry, upon re-reading your output log, I see the problem is actually with the preferences menu... I'll see what I can do ;-)

[uggla]

@ianare wahou ! Thanks for your support !
I'll follow this thread and I will test it as soon as you will give me the green light.

[ianare]

OK it should be working now, can you test the latest master branch?

Thanks!

[uggla]

Hello @ianare,

It is better, but unfortunately I still get a core dump. :(
Here is a report of the encountered issues.

1. Install issue.

messages/update_langs.sh --> ok
make build --> ok

[uggla@ugglalaptop metamorphose2]$ sudo make install
install -d /usr/share/man/man1/
gzip -c9 manpage.1 > metamorphose2.1.gz
install -m 644 metamorphose2.1.gz /usr/share/man/man1/
cp *.html /usr/share/doc/metamorphose2/
cp: cannot stat ‘*.html’: No such file or directory
Makefile:105: recipe for target 'install-doc' failed
make: *** [install-doc] Error 1

Installation is looking for a html file and none is available.
This is a minor issue, fixed by creating a html file at the root of the project.

2. Issue configuring metamorphose.

Language selection --> ok
Popup 'Please take a moment to set your preferences' --> ok
Preferences window --> ok (was not the case before)
Click on ok is working but then metamorphose crashes. :(

3. Metamorphose starts.

Then metamorphose refuses to start. I guess this is normal because the configuration phase was not completed.

[ianare]

Strange, I am not getting any of these warnings and no error on startup. I will see if I can find some info on them.

Which desktop environment are you using?

[bagelskat]

I noticed some files are missing in the master branch compared to the source code for 0.8.2.

make install fails because readme_en.html is missing in the root directory. I got the latest version to install by adding it back.

I was missing a dependency python-wxgtk3.0. Once that was taken care of launching metamorphose worked fine by using the command metamorphose2 -w 3

I'm using Debian Stretch, Gnome 3

I'll be testing it out more soon. Have a pile of files to be renamed. ;)

[uggla]

@ianare, sorry for the late answer. I did not noticed your message above before.
I'm using Fedora 22 and Gnome 3.16.2.

[javierpra]

This is also related to #13 .

[uggla]

@javierpra not sure if the above comment is related to mine. However in my case I manage to build the application.
The problem is when I try to run it, I have a segfault and a coredump...
I tested on my 2 Fedora 22 systems and I got the same on both.

[nerijus]

I was able to launch metamorphose2 on Fedora 23 by extracting only wx-2.8-gtk2-unicode directory to /usr/lib64/python2.7/site-packages from wxPython-2.8.12.0-8.fc21.x86_64.rpm.

[careca1970]

Hi!
I am on Fedora 22, and can run metamorphose2 (either from fc-repo or from git) properly, but only once downgrading wxpython to 2.8.
I get the PIL-message at beginning thou...

What's the actual situation of this issue? Is there a work around that may work for fc22?

Many thanks!

[ianare]

I think the last commit to master fixes this bug definitely.

After much fighting with this problem, I simply removed the preferences dialog on first start.
I'm thinking it was more of an annoyance anyway ;-)

Preferences are of course still available after the application starts up.

Please test, if it works for you I'll release a new version.

Thanks!

[nerijus]

Master still segfaults when launched with -w=3

Edit: it segfaults even when launched without -w=3.
Edit2: it runs when launched with -w=2.

[ianare]

Damn it!

Can you run with the -d option and post the results here?

Thanks much

NOTE: The following may break other applications that rely on wxPython 3

As a workaround the following works. You can downgrade wxPython to 2.8.12. This worked for me on Fedora 24 as follows:

$wget https://kojipkgs.fedoraproject.org//packages/wxPython/2.8.12.0/9.el7/x86_64/wxPython-2.8.12.0-9.el7.x86_64.rpm

$sudo dnf downgrade wxPython-2.8.12.0-9.el7.x86_64.rpm

$cd metamorphose2/

$sudo make all

[uggla]

@ianare I was on fire today and I decided to really look at this issue.

Here is an early report of my findings, I probably need to look deeper in the code however, I think I have found the reason of the segfault.

I'm using Fedora 24 (wxPython 3.0.2)

The line which is causing the segfault is in /usr/share/metamorphose2/renamer/wxRenamerView.py. Line 144.

144         #    opPanel.Destroy()  --> commenting this line will avoid the segfault.

So right now metamorphose is not segfaulting anymore, but the gui is screwed.
That sounds normal as the panel size was probably not defined correctly.

Here is a screenshot:

If someone else could do the same and confirm it is resolving the segfault, that will be great.

@uggla @ianare So Uggla seems to have found the issue. I played with this a bit. I don't know the reason for it yet, but it doesn't seem to specifically like the Destroy() function. Changing this to Close() removes the segfault for me. I don't have much time to play with this as I used to.

line 144 opPanel.Close()

@javierpra 👍
Thanks for checking on your side.

Awesome work on troubleshooting this issue guys! Any chance this might result in a bug-fix release in the near future?

Alternatively.....

Would it be safe to install a parallel (older/compatible) version of python alongside the one which comes bundled with Ubuntu Studio Xenial?

Thanks a bunch :-)

I have created Metamorphose2 Fedora RPMS.
The fix is probably a bit raw. However Metamorphose can be used despite some interface glitches, probably due to wxpython3.
