Crash when deleting multiple nodes

[belisards]

In Debian, Facepager closes itself when I try to delete multiple nodes. Every time I select all nodes and try to delete it, first Facepager deletes just one of the nodes. If I try again, it crashes with this error:

Traceback (most recent call last): File "/home/abitporu/Facepager/src/actions.py", line 141, in deleteNodes self.mainWindow.tree.treemodel.deleteNode(index, delaycommit=True) File "/home/abitporu/Facepager/src/datatree.py", line 326, in deleteNode item.remove(True) File "/home/abitporu/Facepager/src/datatree.py", line 145, in remove self.parentItem.removeChild(self, persistent) File "/home/abitporu/Facepager/src/datatree.py", line 160, in removeChild dbnode = self.dbnode() File "/home/abitporu/Facepager/src/datatree.py", line 185, in dbnode return Node.query.get(self.id) File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/orm/query.py", line 831, in get return self._get_impl(ident, loading.load_on_ident) File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/orm/query.py", line 842, in _get_impl if len(ident) != len(mapper.primary_key): TypeError: object of type 'NoneType' has no len() Traceback (most recent call last): File "/home/abitporu/Facepager/src/actions.py", line 141, in deleteNodes self.mainWindow.tree.treemodel.deleteNode(index, delaycommit=True) File "/home/abitporu/Facepager/src/datatree.py", line 326, in deleteNode item.remove(True) File "/home/abitporu/Facepager/src/datatree.py", line 145, in remove self.parentItem.removeChild(self, persistent) File "/home/abitporu/Facepager/src/datatree.py", line 160, in removeChild dbnode = self.dbnode() File "/home/abitporu/Facepager/src/datatree.py", line 185, in dbnode return Node.query.get(self.id) File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/orm/query.py", line 831, in get return self._get_impl(ident, loading.load_on_ident) File "/usr/local/lib/python2.7/dist-packages/sqlalchemy/orm/query.py", line 842, in _get_impl if len(ident) != len(mapper.primary_key): TypeError: object of type 'NoneType' has no len() Falha de segmentação Segmentation Error

i cannot reproduce this under windows. does the error occur for a minimal database (blank database, just two nodes added)?

[belisards]

With two nodes, if I select all and click in 'Delete Nodes', Facepages deletes only the first. Sometimes when I try to delete the last one, it crashes with:

Looks like a bug in the sqlalchemy library to me, not an Facepager issue. Which version is the library?

See /usr/local/lib/python2.7/dist-packages/sqlalchemy/ or try this one: https://pythontips.com/2013/08/28/finding-the-module-version/

Please try to update your Python installation. Does this fix the error?

[belisards]

sqlalchemy.version '1.1.5'

Python 2.7.9 (default, Jun 29 2016, 13:08:31) [GCC 4.9.2] on linux2

So should I try with Python 3.6?

Versions look ok to me.

Never tried it, by I guess Facepager will not work with Python 3.x, we coded for Python 2.7.

I will setup a vagrant box with debian the next days and try myself.

[belisards]

ok, thank you!

[strohne]

I think the bug is fixed in the latest release (v3.8.1). Could you try it out please? That would be very helpful.

[belisards]

Of course! I've created a new folder and, after clone the repository, tried to run with: 'python Facepager.py'

I don't know if I did something wrong, but Facepager doesn't start and I get this error:

Traceback (most recent call last): File "Facepager.py", line 442, in startMain() File "Facepager.py", line 425, in startMain main=MainWindow() File "Facepager.py", line 60, in init self.createUI() File "Facepager.py", line 240, in createUI self.RequestTabs.addTab(TwitterTab(self),"Twitter") File "/home/abitporu/programas/Facepager/src/apimodules.py", line 668, in init consumer_key=credentials['twitter_consumer_key'], TypeError: 'Credentials' object has no attribute 'getitem'

[strohne]

did you add your credentials to credentials.py? at least copy credentials.py.readme to credentials.py. (see readme.txt for details on how to run under linux)

[belisards]

Sorry, I forgot about it!

Yes, it works nice now. I can delete multiple nodes perfectly.

Many thanks!
