Description Samir van de Sand 2008-01-20 20:14:18 UTC

Version:           2.0 (using 4.00.00 (KDE 4.0.0), Kubuntu packages)
Compiler:          gcc
OS:                Linux (i686) release 2.6.22-14-generic

When downloading files via Kget or Konqueror the downloads get stalled after a while. On the contrary when downloading the same file with Firefox it works fine. I noticed that frequently in downloads from Rapidshare (but also in other cases).

Can you please explain more. :)

when you said "or konqueror" . you mean not using kget at all?

thanks
Manolito

Yeah I mean that this issue occurs while downloading files with Kget or 
downloading files via Konqueror (but without Kget ...). So Kget itself is 
probably not responsbile for the problem, but something more generic. Maybe 
kio?

Comment 3 Maksim Orlovich 2008-01-21 18:00:44 UTC

I'll give this one a shot from kio/konq end, but it may be tricky...

Comment 5 Maksim Orlovich 2008-01-21 19:29:22 UTC

On the app side, the connection backend seems to spin endlessly in the KIO::SocketConnectionBackend::socketReadyRead deferred signal invocation, 
and not actually get any new data, even though it is resumed/buffer set to unlimited, as it thinks it has enough for a header, while it's actually looking for payload. Though fixing that it still stalls, just w/o burning CPU... Some relevant log fragments:

Comment 7 Maksim Orlovich 2008-01-21 21:42:15 UTC

Created attachment 23182 [details]
initial patch

OK, this avoids stalls, but the throughput is subpar, seemingly capping out at
~1.6MiB/sec.

This does:
1. Always re-enables socket notifiers when resuming the backend connection
2. Uses the proper length when computing whether there is an another complete
thing to read -- if we are waiting for payload, HeaderSize bytes is useless.
3. Does multiple reads immediately in a loop. 
w/o (3) throughput is pathetic, as the client can't keep up with the slave.

Comment 8 Maksim Orlovich 2008-01-22 18:00:41 UTC

Ugh.. Something is still wrong --- it appears to occasionally miss some image loading now and such. Not sure how to approach debugging that just yet..

SVN commit 768905 by orlovich:

Fix stalls on long file transfers:
1. Always re-enable socket notifiers when resuming the backend connection 
2. Use the proper length when computing whether there is an another complete 
   thing to read -- if we are waiting for payload, HeaderSize bytes is useless. 
3. Do multiple reads immediately in a loop. 
w/o (3) throughput is pathetic, as the client can't keep up with the slave.

SVN commit 771394 by qbast:

Fix updating location bar for remote directories - if KDirOperator
signals entering a directory then trust it that it is really a directory
instead of using half-working (only for local files) check.
