Re: Two issues with librsvg

Oops, the sample program I gave was missing the call to rsvg_handle_close.
However, adding it doesn't change anything. The corrected program is:

--- cheese.cpp ---
#include <iostream>
#include <rsvg.h>

using namespace std;

static const char s_svg[] = R"EOF(
<svg>
<rect id='cheese' x='10' y='20' width='300' height='40'/>
</svg>
)EOF";

int main() {
    cerr << "RSVG VERSION: " << LIBRSVG_VERSION << endl;

    RsvgHandle* rsvg = rsvg_handle_new();
    GError* error = nullptr;
    if (!rsvg_handle_write(rsvg,
                           reinterpret_cast<const guchar*>(s_svg),
                           sizeof(s_svg) - 1,
                           &error)
        || !rsvg_handle_close(rsvg, &error)) { // <-- fixed
        cerr << "Oops: " << error->message << endl;
        g_error_free(error);
    } else if (rsvg_handle_has_sub(rsvg, "cheese")) {
        cerr << "Yummy cheese!" << endl;
    } else {
        cerr << "WHERE IS MY CHEESE?" << endl;
    }
    g_object_unref(rsvg);
    return 0;
}
--- cheese.cpp ---

It generates the same output (rsvg_handle_has_sub returns false, and the
valgrind memory leak reports).

Thanks,

My main issue is that librsvg seems to not find sub elements by id.
Specifically, rsvg_handle_has_sub returns false, and therefore querying
for the element's size and position fails. I'm probably doing something
wrong here... or is this a bug? I really want the ability to access
sub-elements size and position (by id or name or something along these
lines), so any advice/workaround to make this work would be appreciated.

The secondary issue is that librsvg causes memory leaks, or at least
causes valgrind to think there is such a leak. I can easily work around
this with a suppression file, but... Is there some additional cleanup
function I should call to release all allocated memory?

As you can see in the output (below), I am using version 2.40.13, if that
matters.

Here is the tiny test program:

--- cheese.cpp ---
#include <iostream>
#include <rsvg.h>

using namespace std;

static const char s_svg[] = R"EOF(
<svg>
<rect id='cheese' x='10' y='20' width='300' height='40'/>
</svg>
)EOF";

int main() {
    cerr << "RSVG VERSION: " << LIBRSVG_VERSION << endl;

    RsvgHandle* rsvg = rsvg_handle_new();
    GError* error = nullptr;
    if (!rsvg_handle_write(rsvg,
                           reinterpret_cast<const guchar*>(s_svg),
                           sizeof(s_svg) - 1,
                           &error)) {
        cerr << "Oops: " << error->message << endl;
        g_error_free(error);
    } else if (rsvg_handle_has_sub(rsvg, "cheese")) {
        cerr << "YUMMY CHEESE!" << endl;
    } else {
        cerr << "WHERE IS MY CHEESE?" << endl;
    }
    g_object_unref(rsvg);
    return 0;
}
--- cheese.cpp ---

And a tinier shell script running it:

--- cheese.sh ---
#!/bin/sh
set -x
g++ \
    -std=c++14 \
    -isystem /usr/include/librsvg-2.0/librsvg \
    -isystem /usr/include/glib-2.0 \
    -isystem /usr/lib/x86_64-linux-gnu/glib-2.0/include \
    -isystem /usr/include/gdk-pixbuf-2.0 \
    -isystem /usr/include/cairo \
    -o cheese \
    cheese.cpp \
    -lrsvg-2 \
    -lglib-2.0 \
    -lgobject-2.0
valgrind --leak-check=full --track-origins=yes ./cheese
--- cheese.sh ---

The results are longer:
