Deluge 1.2.3 doesn't work with libtorrent 0.15

[simonbcn]

Deluge 1.2.3 & libtorrent 0.15 compiled from sources
deluged + deluge-gtk remote

It starts well but, after a while, it closes the daemon itself. No error in log!

I hope that you will test well the version 1.3.0 with this libtorrent version to avoid this severe error.

[Ghent]

I've run those versions together just fine. Please don't open tickets that say something "doesn't work". Provide some debug output or some specific (substantiated) problem so that it can be fixed.

[simonbcn]

Perhaps the problem is the very poor information that deluge dumps in log!?
With "deluged -L warning" it shows nothing!

Now I testing it with "deluged -L debug", but in this mode it shows the torrents name and this is private information.

[damoxc]

Star out the torrent names?

However you look at it this is a bad bug report. You didn't even test 1.3, which does work by the way as I am currently using 0.15 with it.

Replying to damoxc:

Star out the torrent names?

Je je, thanks for the obvious comment, but I have many torrents!! I think that debug mode it should hide this info or it has an option to hide this info.

I have tested the v1.3 and I have returned to 1.2.3. See this: ticket 1204

By other hand, I have two tests now with "deluged -L debug" and it crashed the two times but it shows nothing suspect in the log. The last lines in log:

Should I compile the libtorrent in debug mode? Anything else?

[damoxc]

I just tested #1204 and it is now fixed with the latest git master so personally I would just go back to 1.3.

If you really want to find the cause of the problem then running the daemon in gdb and obtaining any back-trace when it crashes.

gdb --args python /usr/bin/deluged -d
run
[[crashes]]
bt

[simonbcn]

Ok, I'm testing the git version.
The first time deluged crashed with this output:

gdb --args python /usr/local/bin/deluged -d

I closed the gdb, I started other time and, so far, it works well. I will let it, in this mode, a few hours more. By other hand, if it doesn't crash, how can I close this gdb mode correctly?

[andar]

What operating system are you using? Are you using eglibc?

It looks like this may be caused by a buggy valloc() in elibgc, which is a known issue.

Ubuntu 9.10 32 bits

Are you using eglibc?

I don't know. How can I find out this?

[simonbcn]

I have searched info in google and I just read this in ​EGLIBC site:

Ubuntu 9.10 Shipped With EGLIBC
Ubuntu 9.10, Karmic Koala, shipped with EGLIBC 2.10 for its C library.

How can I fix it then?

[simonbcn]

There is a problem in this Trac with pending status.
In action now it's marked "leave as pending" but when I submit the comment the status change to new.

[andar]

You can fix this by installing a non-buggy C library.

Je je, thanks for other obvious comment, but eglibc developers have not yet solved.
This bug in eglibc affects to others programs: ​assert hit in eglibc (valloc) with libtorrent v0.15
Christophe Dumez has uploaded a patch to solve this temporally: ​Patch to disable vAlloc in libtorrent v0.15
