Balsa SVN, loop in html rendering with webkit after webkit upgrade

[Jean-Luc Coulon (f5ibh)-2]

Hi,

libwebkit has been updated on debian:

libwebkit-1.0-2 1.1.10-2 -> 1.1.12-1
libwebkit-1.0-common 1.1.10-2 -> 1.1.12-1
libwebkit-dev 1.1.10-2 -> 1.1.12-1

Since that, balsa eats all the CPU on html messages.
Bit I've nothing in a strace on the pid.

I've reverted and everything went fine.

Be warned !

I configure balsa with:


--enable-smime \
         --with-compface \
         --with-gpgme \
         --with-gss \
         --with-gtkspell \
         --with-ldap \
         --with-sqlite \
         --with-ssl \
         --with-gtksourceview=2 \
         --enable-extra-mimeicons \
         --with-libnotify \
         --with-rubrica \
         --enable-threads \
         --with-unique \
         --with-webkit

Regards

Jean-Luc

Hi

Any idea aboutthis issue?

It seems that webkit is still moving (1.1.13 now), with still the same
problem.

Even balsa display a whole black screen when trying to open an HTML
only message.

Regards

I'm still on webkitgtk-1.1.10-1.fc11, so I've yet to be hit by this one  
:)  I *could* upgrade to 1.1.13-1.fc12 from rawhide, but that would  
require also upgrading a lot of other stuff that I use every day, so I  
think I'll wait until beta or thereabouts (reverting would pretty much  
mean re-installing!).

Have you tried running under gdb?  Interrupt with ctrl-C when it's maxing  
on cpu--the backtrace might give a hint as to what's going on.

Best,

Peter

Hmm...I see gtk_widget_size_allocate in the stack.  In the past, Balsa has  
had problems presenting HTML message parts because they are rendered  
progressively, and allocating the ultimate size requires patience.  
Perhaps the widget is slowly growing?  The attached patch reports the  
requested size each time the request is made--could you see what it  
reports?

Thanks!

Peter

I've applied the patch and reinstalled new wemkit libs (1.1.13-1)

I've the following in the xtrm when I open an HTML message:

lbh_navigation_requested_cb about:blank

At the same time, I've a popup in the balsa windows (even with the "C"
locale, it is displayed 1/2 in English, and 1/2 in French):


Erreur showing about:blank: L'emplacement indiqué n'est pas pris en
charge

The French part means "The specified location is not supported"

When I click the OK button on the popup, I've the following message
endless in the xterm:

lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0
lbh_size_request_cb width 0 height 0

Git master has been patched to not max out the CPU.  In a few tests, it  
still displays correctly with WebKit 1.1.10.  With 1.1.12 and later, it no  
longer hangs with the CPU pegged, but neither does it display the content  
:(

There's a reason WebKit support is still labeled "experimental"!

Insights from anyone with experience with WebKit are invited.

Peter
