[binarycloud-dev] Strangness in a "stack truncation"

[Justin F. <je...@ey...>]

Alex/Guys:

I am having a problem/bug that I am spending way too much time
on chasing.

Since I am not experienced with BC, this problem I tend to "blame"
on the different platform/environment, as the code seems right.

So, I am summarizing this problem for that case that Alex or
someone will recognize as a BC problem, or that it must be some
subtle error in the code.  OTHERWISE DON'T WASTE ANY TIME ON THIS.

I have a module Warning.php that collects non-fatal warnings for
the application and prints them out in a "pane" of the page render.
I have another module that does a lot of database work in the
constructor, and that is where this stack of warnings is most
exercised.  I have scattered some printf's for debugging.

Basically, in this stack in a module that has already been instantiated
and is collecting warnings from a constructor "behind" it, looses its
stack when Output() is called by BC for the module.

viz (the Before/After bracket the new in Page.php):
Before instantiation of lib.EyeLibrary
After instantiation of lib.EyeLibrary
Before instantiation of astronomy.LookupTable
After instantiation of astronomy.LookupTable
Before instantiation of lib.Warning
After instantiation of lib.Warning
Before instantiation of astronomy.Top
After instantiation of astronomy.Top
Before instantiation of astronomy.Nav
After instantiation of astronomy.Nav
Before instantiation of lib.EditTable
In EditTable constructor
setWarning called...with [You have asked for a record that is greater
than the number in the data set. Record set to last record.]. Now 1
warnings on stack.
setWarning called...with [Right after existence]. Now 2 warnings on
stack.
setWarning called...with [Right after existence]. Now 3 warnings on
stack.
After instantiation of lib.EditTable
===  Above gets printed before page render

And, in the page render (Output) I get:
setWarning called...with [Test inside
/usr/local/binarycloud/build/en/user/mod/lib/Warning.php]. Now 1
warnings on stack.

only one on the stack, and that was a "phoney" call to the
Warning->setWarning()
in Warning->Output().  I lost all the warnings made in the consstructor
of EditTable.

This is the method in the lib.Warning module:
------------------------------------------------
        function setWarning($msg="Unknown warning") {
                $this->HaveWarning      = true;
                array_push($this->Warnings,$msg);
printf("setWarning called...with [%s].  Now %d warnings on
stack.<br>\n",
        $msg,count($this->Warnings));
        }
--------------------------

NOW NOBODY SHOULD WASTE ANY TIME ON THIS unless someone has had a
similar
problem and it is, somehow, related to the BC environment.
