Description Amilcar do Carmo Lucas 2004-07-20 19:35:24 UTC

Version:           0.1.3 (using KDE 3.2.3, SuSE)
Compiler:          gcc version 3.3.3 (SuSE Linux)
OS:                Linux (i686) release 2.6.5-7.95-default

When I check www.kdevelop.org using 4 levels and external links,
It crashes after cheking around 2000 links (mid of the third level).

Comment 1 Paulo Moura Guedes 2004-07-20 19:56:16 UTC

Do you have a backtrace? My DNS server is real slow in the last days and it takes hours to check 2000 links :(

Comment 2 Amilcar do Carmo Lucas 2004-07-20 23:30:15 UTC

I got this crash after 100 entries or so, so I'm not sure it's the same one:
#0  0x616c702f in ?? ()
#1  0x401865cb in KIO::Slave::gotInput () from /opt/kde3/lib/libkio.so.4

#15 0x08050475 in main (argc=1, argv=0xbffff104) at /mnt/home/be/sources/kde/kdewebdev/klinkstatus/src/main.cpp:94

this was captured using:
gdb klinkstatus

It only crashes after 2000 checks when used without gdb

Comment 3 Paulo Moura Guedes 2004-07-20 23:38:05 UTC

That backtrace seems to show a KIO bug... I guess that if you try again you won't be able to reproduce it (at least around the 100th link).
Here, after 4 hours I already checked 2477 links in kdevelop.org.
Do you have qt-copy or Trolltech's Qt?

Comment 4 Amilcar do Carmo Lucas 2004-07-21 00:07:08 UTC

qt3-3.3.2-6 from SuSE 9.1 YOU
I'm doing a second attempt and so far I've covered 800 links without a crash :)
I'll post the bt if I get one later.

Comment 5 Paulo Moura Guedes 2004-07-21 00:14:36 UTC

I was having this crash also before I changed my Qt to KDE qt-copy. I think it is a QTable bug, that is fixed in qt-copy. Trying with qt-copy would the best.
Anyway, I already started to replace QTable with KListView so one can choose between a tree or flat display.

P.S. 3072 links checked until now ;)

Comment 6 Sebastian Stein 2004-08-31 00:18:25 UTC

I can confirm this bug, also having the official Qt packages installed. The backtrace is the same, but it crashes after 600 links while checking his.hpfsc.de with external links and 5 recursion levels enabled.

Comment 7 Andy Talbot 2004-09-04 23:39:28 UTC

I get similar segment violation crashes (SIGSEGV) with a *live* web site, but can completely process a *copy* of the same site on hard disk.  So, perhaps there is a problem in connection with kio_http that does not exist in connection with kio_file.  BTW, I am using SUSE 9.0 with QT at version 3.3.3-11.

Comment 8 Andy Talbot 2004-09-05 17:30:05 UTC

Correction: it does crash on a hard-disk copy of a web site after all. :(

Comment 9 Amilcar do Carmo Lucas 2004-09-23 11:08:52 UTC

Ok, Here is a better trace. Using HEAD with Qt 3.3.3
This time it crashed while "adding a new level"
The test URL is www.kdevelop.org

Comment 10 Amilcar do Carmo Lucas 2004-09-28 10:41:29 UTC

This one is a real "show-stopper". This bug makes the hole program useless for me.

Maybe this is same bug:

Can you tell me more details like the site you were checking, number of links

Finally a site I can reproduce. It seems KIO related though...

Well, I can reproduce it with Fedora 2. Now I tried with Yoper (kde-3.3) and 
it went on fine. Tomorrow I will try Yoper, with kdelibs from CVS, and 
Kubuntu :)
Finn, can you tell more details about your distribution and kde(libs) version?

I don't think so because when the content type is not text/html, KLinkstatus 
only performs a HEAD request.

With Yoper: reproduceable with kde-3.3 but not with kdelibs from CVS (ceteris 
paribus). It would be interesting that you would try with KDE 3.4

Created attachment 12263 [details]
KIO patch

This patch fixes this crash. It's not a fix in KLinkStatus but in KIO (which
belongs to kdelibs), so I hope it is correct and can be commited ASAP.

Comment 21 Paulo Moura Guedes 2005-08-20 01:17:19 UTC

SVN commit 451129 by mojo:

Don't delete the slave twice.
This prevents random crashes in KLinkStatus.

Still can't find anything wrong made by the application but, anyway, the fix in kio solves the problem.
Closing the bug.
