Question to SoulseekQT (Linux)

Soulseek General Discussion

Hello!

I use SoulseekQT 11/16/2012 in Ubuntu Linux V 12.04, and there seems to be a bug:

When I click in "Downloads" the button "Clear Complete" in the upper row, or in "Uploads" the "Clear Complete and Aborted" the Soulseek program often crashes down. I don't remember that I saw this issue in the older version SoulseekQT 10/16/2012; that should be rather new.

Let me also ask a question:
In SoulseekNS the "Upload Slot" configuration was "overrided", when a user of the user list wanted to download from me. For example, when I have configured "1" in the "Upload Slot", and another user being registered in my user list came to download something, he was automatically privileged and could download additionaly as if there were "2" Upload Slots. Is that different in SoulseekQT or have I forgotten anything to configure?
It doesn't matter which "User Group" I configure to a listed user.
If this feature is not intended in this way in SoulseekQT: Can you add this? It was very handy.

Excuse my bad English! ;-) Soulseek is a great idea, and I love it!

Hi xix,

Regarding the crash, see this thread.

Regarding the upload slots, issue, Soulseek NS has an "Extra userlist upload slots" feature that SoulseekQt does not currently have. You can however change the download priority of a particular group using Users->User List->Configure User Groups to give users in that group a higher download priority.

Thanks, Nir

Hello Nir,

now I tried using the SoulseekQT 11/22/2012 again, and I runned it using "gdb". First it worked all normally, I could remove ready downloads. But after a while I did the same again and then a freeze came up, and the gbd said the following, shown at the bottom line:

Does this report tell you what the matter is/was?

It happened already that this Soulseek version crashed down suddenly without doing anything!

Did you check the thread I linked you to? This might be related.

Submitted by xix on Mon, 11/26/2012 - 15:59.

Sorry, I didn't read the link more below. There you say, that the guilty part is the QT4 library 4.8.1. Exactly the same I have installed/updated in my Ubuntu 12.04.

Well, I dunno if there is a way in Ubuntu to downgrade to 4.7.4. If not, I can go on using the SoulseekQt 10/16/2012. This didn't crash down until now.

BTW: I use the 32bit version. I think I must hope that there will be another upgrade from 4.8.1 to a newer one, and this will work then better.

Submitted by Nir on Mon, 11/26/2012 - 16:34.

I do hope so. I should probably report this bug.

Submitted by Nir on Mon, 11/26/2012 - 17:39.

I may have some good news for you, stand by.

Submitted by Nir on Mon, 11/26/2012 - 19:29.

Well, turns out it's fixable. See the thread I linked you to for a technical explanation. Or you could just try it out yourself:

now I set up the new SoulseekQt 11/26/2012. First all looked good, I could work normally. But now, when in the "Uploads"-Folder users were ready with their downloads, and I clicked the "Clear Complete and Aborted" the program freezed again. Seems indeed so as if the QTlibrary 4.8.1 is the evildoer (?)

Here is a gdb debug list again, now together with the "bt" report:

Let me add a note: I assume that these described freezes or crashes happen especially when there are many completed or aborted entries in the Upload/Download window.

Submitted by Nir on Tue, 11/27/2012 - 19:28.

Yeah, I see where this is happening. These are very similar bugs to the original one. Give me a few and I'll link you to another build.

Let me know how it works for you!

Thanks, Nir

Hello Nir,

I think I can tell you a god message!

After updating to SoulseekQt 11/27/2012 I watched no more problems. The "Clear Completed and Aborted" in "Upload" and the "Clear Complete" in the Download window did no longer crach down or freeze this day

I thank you a lot!

Thanks xix! I can go ahead and make another release then.
