KDESVN 0.8 is slow to refresh at times

[SteamedPenguin]

KDESVN intermittently will wait a few second on expanding or closing directories in a local working copy.

ADDITIONAL INFORMATION: I am using my own ebuild, as attached.

hm..... well, when FIRST open a folder tree it may hang a short time (due reading in the content) when content below is real large. but after that this is a pure treeview repainting operation. So I should know how many items are under that folder you expand?

When using your ebuild - which compiler flags are set?

[Nick]

I just came here to report similar issues with 0.8. But what I have noticed is that when I expand a local directory tree (and it hangs for a few seconds), it corresponds with a lot of upload network traffic - i.e. it seems to be checking the remote repository against local tree?

This is all with nothing else running on my desktop, so it is kdesvn 0.8 that is inducing the network traffic?

You may check the option "Check for updates when open a working copy" in Settings. If set kdesvn start a scan for newer items - thats why the traffic. And thats why you may switch it off ;)

[Nick]

That was the first thing I checked to see if it was on. I have even turned off the 'logs follow node changes' and 'logs always reads lists of changed files'.

Even with an open local copy, this happens randomly when just opening trees/closing trees again - network traffic shoots up, and kdesvn freezes for about 10 - 20 seconds.

Then it all works again until maybe 3 minutes later... repeat.

I have added a screen shot - you can see now. kdesvn is waiting and a lot of network...

Strange. kdesvn doesn't check again and again. And this happens when re-open a tree, too?

The statement for (local!) status will just send when a folder is open the first time. Means when closing/opening trees with items nothing happens than a repaint of treeview. Or should. I'll check it again today.

[Nick]

Yes. Basically if I just sit there opening and closing trees, every few minutes it happens again. As you can see in the screenshot, with the Bashburn repository there is only (say) 3 files in one tree - but we still get the 20 second odd hang with network traffic.

This is with all options to update turned 'off'.

Thnaks for looking into this. kdesvn is the best application I have used for a long, long time :-)

OK, a bit more info. I set up a connection tracker on my gateway - here is what happens when kdesvn does the 'freeze', using kdesvn local copy, and opening/closing trees (my box 192.168.1.23).

Prot Src IP Src Port State Dst IP Dst Port

etc. etc.

There is a lot more of these connections (only a sample above). Plus I also now see that ssh-agent sometimes doesn't get closed when kdesvn is closed - this appears to happen if you close kdesvn when in this 'froze' state.

OK, just to confirm. I just rebuilt 7.4 and it does not exhibit this behaviour when opening/closing local trees.

8.0 does indeed do some sort of network activity when doing similar that freezes the GUI for a bit, and can be induced easily.

If you need any debugging info, I can help.

Nick

[alwin]

Ah! just an idea: do you have the tooltip-option enabled? eg, will kdesvn display a small tooltip when mouse is touching an item?

If yes - what happens, when you disable it?

[Nick]

You mean 'Show file info' ?

Yep!!! That's it!! No more network activity, and opening/closing trees is fast !!

Good job!

Nick P.S. I am just about to submit index.doc - I have attempted to clean up the English a bit. This is pass #1.

[alwin]

on your side the same, SteamedPenguin??

[SteamedPenguin]

Thanks Nick for the investigation. Yes, Turning off all the stuff Nick mentioned made KDESVN perfect.

[Nick]

The culprit is 'Show file info'. That is the only thing to turn off to stop this behaviour - all the rest can be turned back on again if you wish.

Nick

[alwin]

should be fixed - it seems it was a problem when retrieving some infos (wrong revisions given for it)

[Nick]

Confirmed - new build this morning (781) appears to work good with 'Show file info' turned on.

Good job!
