Fw: Gnome extensions

[Leslie S Satenstein <lsatenstein yahoo com>]

Do not (as 5 October) use Gnome with btrfs.  You can experience gnome-shell looping with 99% cpu busy,  schemas not being adhered to, and problems because btrfs uses copy-on-write.  I have 5 copies of Gnome 3.26 with ext4, brtfs fully, btrrs with xfs for /home  and more. I can substantiate the btrfs problem. Like any scientific experiment, you can duplicate my findings.

Gnome is safe with  a non "copy on write" file system.

Hi Florian

I'm using a few of your Gnome extensions.  I thank you for providing them to the community. 

I do have a question for you regarding the gnome-shell.

I have extensions (several that include yours), where the installation (doing the settings) onto a btrfs file system crashes the shell, or causes the shell to go into a 99.9% cpu loop.  If I install these extensions onto a non btrfs system, eg, ext4, lvm, xfs ,   the installation and extension setup works flawlessly. 

I use most of your extensions, that come globally with Fedora Linux (currently using the Fedora beta 1.5, the pending go-live beta). I am using it fully with btrfs.  I can crash the shell with one or two extensions, only if the underlying file system is btrfs

As the gnome-shell gets maintenance updates, I am see fewer and fewer crashes, but not with btrfs. The crashes only occur during parameter setup. It seems that the gnome-shell does not wrongly read the compiled schema or ignores the compiled schema.  Have you stress tested Gnome-shell under btrfs?  

My preferred third party extension that works perfectly with ext4 and xfs is TaskBar by Zpydr. I am walking through the source code and with my level of JS knowledge, find no errors. Setting TaskBar up onto a btrfs system crashes the shell, but on logging in after a crash, I see settings outside of the schema settings.  After a few crashes, when the settings are what I wanted, every extension works as anticipated.  By the way, I am not the author of this extension.  The author appears to have abandoned his offering.  What is his extension and one or two others exercising that cause this grief.

 

 I am wondering if recompiling the schemas while under btrfs would make a difference. I will give it a try.
