Please apply, but mention a little more about about why. For instance, "so that
it is called before the default signal handler, which would otherwise claim to
have fully handled the signal by returning false/true/iforget"

Summary: Patch to silence an 'unused parameter' warning
Product: gnomemm
Version: unspecified
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: libgdamm

GNOME milestone: Unspecified
[Forwarded from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=472834 ,
reported by Norbert Kiesel <[EMAIL PROTECTED]>]
An unused parameter in libgda/libgdamm/value.h may cause a warning using strict
g++ option, which in turn can be promoted in to an error with -Werror and is
not good for software depending on it. The patch from Norbert silences it by
commenting out the unused parameter.

gtkmm | TreeView | Ver: 2.12.x
Summary: Gtk::ListStore::reverse_iterator doesn't work
Product: gtkmm
Version: 2.12.x
Platform: Other
OS/Version: All
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: TreeView
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
GNOME version: 2.21/2.22
GNOME milestone: Unspecified
Steps to reproduce:
$ cat rev_iter.cc
#include <iostream>
#include <gtkmm.h>
struct Columns : public Gtk::TreeModelColumnRecord {
Gtk::TreeModelColumn<int> col;
Columns()
{ add(col); }
};
int main(int argc, char *argv[])
{
Gtk::Main m(argc, argv);
Columns columns;
Glib::RefPtr<Gtk::ListStore> model = Gtk::ListStore::create(columns);
(*model->append())[columns.col] = 1;
(*model->append())[columns.col] = 2;
(*model->append())[columns.col] = 3;
(*model->append())[columns.col] = 4;
(*model->append())[columns.col] = 5;
for(Gtk::ListStore::iterator i = model->children().begin();
i != model->children().end(); ++i)
std::cerr << (*i)[columns.col] << std::endl;
for(Gtk::ListStore::reverse_iterator i = model->children().rbegin();
i != model->children().rend(); ++i)
std::cerr << (*i)[columns.col] << std::endl;
return 0;
}
$ g++ `pkg-config gtkmm-2.4 --cflags --libs` rev_iter.cc
$ ./a.out

Stack trace:
a not-so-very useful stack trace:
#0 0x00000000213582a3 in ?? ()
#1 0x00000000004022f2 in Gtk::TreeRow::get_value<int> (this=0x7fff66bf2570,
[EMAIL PROTECTED]) at /usr/include/gtkmm-2.4/gtkmm/treeiter.h:482
#2 0x0000000000402354 in Gtk::TreeValueProxy<int>::operator int
(this=0x7fff66bf2920) at /usr/include/gtkmm-2.4/gtkmm/treeiter.h:436
#3 0x0000000000401c2e in main (argc=1, argv=0x7fff66bf2a28) at rev_iter.cc:31
Other information:
the crash happens because:
a) Gtk::TreeRow inherits from Gtk::TreeIter
and so when you dereference an TreeIter it just returns a reference to itself
TreeIter::reference TreeIter::operator*() const
{
return static_cast<const TreeRow&>(*this);
}
b) when you dereference a std::reverse_iterator it does:
reference
operator*() const
{
_Iterator __tmp = current;
return *--__tmp;
}
of course, what reverse_iterator doesn't know, is that it is in fact returning
a reference to __tmp. And since __tmp is a local variable, it deletes it just
before returning (and thereby deleting the value which it is returning)
so, basically, it returns some random value, and using that value buys you a
ticket to core dump land
as for solutions, i can think of a few, but none of them is really good or
easily doable:
1) make your own reverse_iterator that somehow avoids this kind of thing
- doesn't solve the real problem, since a similar thing can creep up in other
situations
2) make a _real_ iterator instead of having TreeRow inherit from TreeIter
- takes a lot of coding and breaks all kinds of APIs and ABIs
