Problems writting new kioslave.

[Marc Mauri Alloza]

Hello,

As part of my Season of KDE project I'm writting a kisolave to get and
write files concurrently by different users. To do it I'm doing a
kioslave that will use Telepathy and maybe infinote protocol. At the
moment I'm trying to make that the get() method of the kioslave
returns a "plain/text" file with the username of the telepathy
accounts that I have configured.

When I run it I get an anoying error:
kioclient(3854)/kio (KRun): KRun(0x885dac8) ERROR (stat): 143 "The
process for the infinote protocol died unexpectedly"

I've tried many things.

You can find the code in this git repo:
https://github.com/opengeekv2/Kio-Infinote

Thanks.

Could you please tell me if you are testing the slave by launching it
in konqueror/dolphin or using your own test program or kioclient?

Over the top of my head I'm going to venture that this has something
to do with not
having overridden SlaveBase::stat() or there is an actual crash bug in
your code.
It would be great if you could switch on debugging information and try
again and paste some
kind of log here.

I think the steps to enable debug from a certain terminal are:
1. run kdebugdialog and enable the kio related debug channels
2. run kdeinit4 from that terminal
3. run the slave.

KDE debugging is a new world for me.

I paste output here:

As far as I can see at least the kioslave is instantiated. I'll
program the stat() function and see if it solves the problem.

Thank you :)

Seems to be a programming bug to me. The best thing would be to insert
kDebugs() at appropriate
points in the program to see what point it reaches before the crash.
gdb with kio is not pretty, hence print stuff out.

I've enabled all debugging outputs you said and here's the output:

Why my kioslave is so slow?
