Plugin initiation hangs with segmentation fault on geany 0.21 with python 2.7.2 on arch-linux #3

Got this error on gdb and bt

Can you post the code of the plugin being loaded (if any)?

Also can you try deleting (or emptying) the file ~/.config/geany/plugins/geanypy/plugins/.loaded_plugins and see if it still crashes?

sagarchalise commented 12 years ago

I was not trying to load any plugin written with geanypy. I guess I have to load GeanyPy first and it happened when I was loading/enabling GeanyPy . I tried what you said but still doesnot work. It crashes with segmentation fault as soon as I check the plugin loading box for GeanyPy.

Hmm, any chance of trying again with gdb or even valgrind and using the -v argument to Geany? I can't tell what's going on from that backtrace since the calls before that memory access message are all inside Python itself.

If I enable it through geany.conf and then load gdb I get this otherwise its the same as above when I run geany and then enable it (gdb) run -v Starting program: /usr/bin/geany -v [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/libthread_db.so.1".

UPDATE: Seems like I need to load the GeanyPy plugin first then I need to load others. Its working right now. let me see if I can trace something more.

codebrainz commented 12 years ago

It's probably a conflict with the Zen Coding plugin since both load the Python interpreter and I have doubts whether this would work OK. Eventually I want to port the Zen Coding plugin to be a GeanyPy plugin to avoid this conflict.

Do you mind trying combinations of both to see if it is a conflict?

sagarchalise commented 12 years ago

Well I am using both. If I enable geanypy through geany.conf and then start enabling other plugins through GUI. I havenot faced any problem. On a very different note, Does GeanyPy work with older geany i.e. 0.20 or 0.19 ?. I want to package GeanyPy and Geany-Zencoding for ubuntu as well as archlinux. Especially in ubuntu, 0.21 is not shipped until 12.04, so wanted to know if it works on older version ? I have already setup ppa https://launchpad.net/~chalisesagar/+archive/geany-extras.

Anyway let me see if I can catch anything else. But now its working smoothly [Both plugins].
