Seafile Extension: Transport Error
j0hannes opened this issue · comments
Dolphin recently started to crash when opening a seafile folder. Running it with valgrind, I see the message "Seafile Extension: Transport Error" in dolphin and the following warnings on stdout:
(process:14914): Ccnet-WARNING **: 18:02:46.372: [client pool] Failed to connect.
(process:14914): Ccnet-WARNING **: 18:02:46.385: [Sea RPC] Failed to get client from pool.
This is the backtrace when run outside of valgrind:
Application: Dolphin (dolphin), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Thanks for reporting. I already discovered this myself, but am currently not able to work on the problem. I should be able to find the time within the next to weeks. Until then you will have to deactivate or uninstall the plugin to make dolphin usable again.
Okay, so the reason for the crash was simply me using the wrong method to free the error.
The reason for the error appearing seems to be that the current seafile runs without ccnet - which means I can't connect to it using ccnet. I will have to figure out how to connect in a different way...
Has been fixed by directly connecting to seafile using a local pipe instead of ccnet as proxy. Has been released and AUR was updated - wich means you should be fine with Version 1.1.0
Also, thanks to your stack trace I was able to fix the crashing itself, which means from now on errors like this one will only generate an error message and not crash anymore
Yes, it's working now. Thanks for this plugin. 👍
