No, it wasn't (also because ecore doesn't use threads)... It was just a
bug in ecore that now seems to be fixed. It practically aborted in some
situations that aren't fatal at all.
After that ecore modification (available since its svn commit r39913),
the mentioned bug was fixed.
However during those days I've also fixed any other bug and now the
client (look at the attachment!) seems to work without any segmentation
fault, abort or any other error, however my connection troubles aren't
over yet. :/
I'll re-post here the tests results that I've just posted in e-devel :
- Using the "prpl-msn" protocol in HTTP mode I was always able to
connect, get messages, notifications and so on.
- Using the "purple-jabber" protocol (Google Talk) I was always able
to connect, get messages, notifications and so on.
- Using the "prpl-msn" in standard mode (so, like this client generally
does) with my account (that is a very "heavy" one since I've to load
something like 450 contacts) I can connect, load contacts and so on
but I really I can sign-in in the server (I mean that I'm visible to
others and I get notification/messages) only if I run the client in
valgrind and with libpurple debug enabled! Yes, this is so weird as
I only once was able to connect to it running it in the normal way...
Nevertheless, the "valgrind+debug" way seems to work always! :|
- Using the "prpl-msn" in standard mode with some other MSN accounts
which count less contacts (yes, I know, I've to contacts! :D), both
the "standard" and the HTTP connection methods work as expected.
So actually I don't know where's the "bug", I only know that it has a
very strange behavior and that it doesn't happen using the glib
nullclient. Nevertheless this code is quite ready for being used.
So, please, if you have any idea... :)
