Hi,
I have an issue with the layout code on firefox and 1.9.0.4/5
layout/generic code. OS is EMC's Unix aka a typical SVR4. Some piece of
code in layout/generic related with reflow goes wrong and honestly I
cannt see why! I have attached a log. The main intersting source file
is the nsFrame.cpp and its related headers... Especially in the
function/constuctor nsFrame::Init we find a
if (IsBoxWrapped())
InitBoxMetrics(PR_FALSE);
IsBoxWrapped() returns FALSE on EMC Unix regardless what!
I am pretty sure I have seen something about IsBoxWrapped return
ing false on other OS's too (not linux of course!). But its some
time now and I cannt remember where. Removing the if (IsBoxWrapped())
is not a solution at least on the latest 1.9.04 XUL. It drives us to more
trouble.
Well for sure on EMC's unix IsBoxWrapped=false and So InitBoxMetrics is
never called!
After say an xul build I am giving:
cd dist/bin
./xulrunner ../xpi-stage/simple/application.ini
(note" $(DIST)/bin is already declared on the system's LD_LIBRARY_PATH).
I ve put some printf's on this spot (nsFrame.cpp) and also on prlink.c
(nspr) that controls the various dlopens.
nsFrame.cpp
// EMC/UX
if (IsBoxWrapped())
{
printf("### InitBoxMetrics is called ###\n");
InitBoxMetrics(PR_FALSE);
}
else
{
printf("### What the heck? InitBoxMetrics never called? ###\n");
}
Please take a look to the attached log. Pretty much too many "What the
heck? InitBoxMetrics never called?"
But, say in linux that I ve test it too, there is also just one
"InitBoxMetrics is called"!
The attached log dumped core and is being debugged. As I said
InitBoxMetrics was never called. The cores on xul are always on BoxReflow
and I have ask gdb to show me the args for this function. Can you tell
which one is wrong and make BoxReflow gone? (see my log).
All these functions, IsBoxWrapped, InitBoxMetrics, Init, BoxReflow are
parts of layout/generic, so if I understand what is going wrong I am pretty
sure I can fix it for EMC Unix.
Primarily I want to make sure: if InitBoxMetrics never called would that
cause BoxReflow to fail later on?
Kind Regards,
PS: compiler is GCC 3.4.6
