BiglyBT freezes and hangs up when interacting with the GUI interface

[chauhansarthakiitd]

Hi, right now I'm on fedora, and before I was on ubuntu-mate so it's not the system (read further). because of all the freezes and hangs up I downgraded to 1.6 and had no problem and the app automatically updated itself and there was no problem BUT after the update BiglyBT downloaded this package: swt_swt-4942r22-gtk-linux-x86_64.zip after the update and restart freezes and hangs up came back could you look into this, please? It's obviously a problem with legacy swt and/or gtk

Try grabbing the latest SWT from

https://download.eclipse.org/eclipse/downloads/drops4/S-4.23M1-202201051800/#SWT

and see if that helps. Grab swt-4.23M1-gtk-linux-x86_64.zip, unzip it and replace the "swt.jar".

When running check the BiglyBT "About" dialog to verify you have updated correctly.

thank you for the link. I tried it and it seems to be working. but I'm still on the fence. if something were to happen again I'll reply

thanx, mohsentux

EDIT: Scratch that. didn't work. I will try other older versions until one of them works

EDIT 2: I tried several other versions none of them worked so I decided to run biglybt from terminal to see what output the terminal gets. I clicked on one of the files held down shift key and tried to pick several downloads and it printed this output snippet and crashed and exited:

WARNING: A terminally deprecated method in java.lang.System has been called WARNING: System::setSecurityManager has been called by com.biglybt.core.security.impl.SESecurityManagerImpl (file:/home/mohsentux/biglybt/BiglyBT.jar) WARNING: Please consider reporting this to the maintainers of com.biglybt.core.security.impl.SESecurityManagerImpl WARNING: System::setSecurityManager will be removed in a future release No shutdown tasks to do BiglyBT TERMINATED.

I'm trying my best to find legacy swt.jar file versions. but eclipse is jungle and I don't know how to navigate through it. I've already tried all the versions that were available at the link with no success, where does eclipse keeps its old swt.jar files?

[chauhansarthakiitd]

I'm trying to see if this error is also on BiglyBT's standalone Jar file from github, but I don't know how to run it:

$ java -jar GitHub_BiglyBT.jar

Error: Unable to initialize main class com.biglybt.ui.Main
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

That's just a warning that I know about - it doesn't cause any issues itself.

You can't just run that jar by itself - you need to rename it to BiglyBT.jar and replace the file in installation folder with it. That .jar is exactly the same as the one in the release's installers though.

I've tried many versions of SWT over the past year, tried deleting ~/.biglybt a few times, different distros, but never found anything that makes Biglybt not crash or hang when interacting with the interface.

From my experience, the more torrents are loaded, the higher chance clicking on something causes it to crash or hang.

I try to do as much with the web interface, but there are many features missing on it unfortunately.

[chauhansarthakiitd]

I believe the only way to fix crashes is using the process of elimination if I select a torrent in downloads nothing happens but let's say I have 15 downloads if I select the fifth torrent and hold shift and click on the tenth torrent It'll crash. does this help narrow it down?

[parg]

The issue(s) only occur on Linux - OSX/Windows don't have these kind of bugs.

It doesn't happen on all types/window managers/versions of Linux.

My Kubuntu VM for example exhibits no issues.

The problem isn't with BiglyBT code, it is with either SWT or GTK.

So it is really rather hard to diagnose.

[parg]

(oh, and Eclipse, the organisation responsible for SWT, do not seem very interested in fixing stuff)

[chauhansarthakiitd]

unless we experiment by defining everything as a constant and gtk or swt as the variable, we can't be sure that, that's causing the issue. I'll download the kde plasma for my fedora 35 and test it again.

[chauhansarthakiitd]

I tracked down the problem to this file:

swt_swt-4942r22-gtk-linux-x86_64.zip

I installed the kde environment (didn't help with the bug). started an old version of biglybt so it would auto-update, after updating to 2.9 it was fine after restart then started downloading this file : swt_swt-4922-gtk-linux-x86_64.zip required restart and after that it still was fine but then it started downloading swt_swt-4942r22-gtk-linux-x86_64.zip after a restart bug reappeared.

so where do we go from here? where is swt_swt-4942r22-gtk-linux-x86_64.zip repository and how do I install older alternate versions or nightly builds and snapshots. the file list of all of it's versions should be on the internet right? they're always like this.

Latest releases:

https://download.eclipse.org/eclipse/downloads/index.html#Latest_Release

Archived:

https://archive.eclipse.org/eclipse/downloads/

The mapping from release (e.g. 4.20) to version number (4.20 -> 4944r26) is not obvious, you have to download the SWT .zip, extract the swt.jar from it and then look in the swt.jar for the DLL names that include the version number.

Another alternative are the maven releases:

3.106.1	4.758
3.106.0	4.757
3.105.3	4.629
3.105.2	4.628

Note: From Versions 3.109.0 (4.922) and older, the UI starts to break, also note that BiglyBT will force you to update swt lib to 3.116.0 (4.942) automatically if you try those older versions. On my case the older swt lib jar at "/opt/biblybt/swt/swt-x86_64.jar" was replaced by "/opt/biblybt/swt/swt.jar" during the update.

Another note: On my case, downgrading/upgrading swt lib had no positive effect on the discussed problem whatsoever, only adding severe UI glitches while freezing the system UI at the same time.

I'm happy to announce, after waiting so long, the situation is resolved. I no longer have any problems with the newer version of the app. I propose closing this issue

[davidalb97]

Did you do anything new to solve it other than just updating?

[chauhansarthakiitd]

All I did was an update. that's all

I've been having issues with SWT on linux for well over half a year now. I found that the BiglyBT console ui works great to an extent but the overall capability of both cli and the Web Remote plugin is fairly weak. Today I discovered an untraditional way of getting around this issue by running Bigly in Wine, as this allows me to use it without freezes or crashes, and I can also use linux for everything else on the machine, like ZFS for example. Are there any immediate downsides to this solution?

I don't think there are any problems when emulating, there is however, a performance impact.

I found out that I could avoid KDE from freezing when not opening the Application Drawer from the Panel (taskbar), opening biglyBT from the terminal. Not having erroring torrents (archiving when missing files) also helped from freezing until the Application Drawer was opened, allowing me to use the KDE Panel (as long as no Application Drawers of any kind were opened).
