Hello masters, I'm newbie here.
Well, I need to develop a DB application, so libgda will help me a lot in
that task. However, doing some two basic tests, I found memory in both:
#include <libgda.h>
int main() {
GdaConnection *connection;
g_print("CONNECTING\n");
connection = gda_connection_open_from_dsn("calvaris", NULL,
GDA_CONNECTION_OPTIONS_READ_ONLY, NULL);
if (!connection) {
g_print("CONNECTION FAILED\n");
return EXIT_FAILURE;
}
g_print("CONNECTED\n");
g_object_unref(G_OBJECT (connection));
return EXIT_SUCCESS;
}
result:
CONNECTING
CONNECTION FAILED
=================================================================

Same leak using a valid connection:
#include <libgda.h>
int main() {
GdaConnection *connection;
g_print("CONNECTING\n");
connection = gda_connection_open_from_string("SQLite",
"DB_DIR=.;DB_NAME=test.sqlite3", NULL, GDA_CONNECTION_OPTIONS_NONE,
NULL);
if (!connection) {
g_print("CONNECTION FAILED\n");
return EXIT_FAILURE;
}
g_print("CONNECTED\n");
g_object_unref(G_OBJECT (connection));
return EXIT_SUCCESS;
}
result:
CONNECTING
CONNECTED

Why?! :-/
My CMake file:
cmake_minimum_required(VERSION 3.6)
project(testes)
set(CMAKE_C_STANDARD 99)
set(CMAKE_C_FLAGS "-g -fsanitize=leak")
add_definitions(-I/usr/local/include/libgda-5.0)
add_definitions(-I/usr/local/include/libgda-5.0/libgda)
add_definitions(-I/usr/include/glib-2.0)
add_definitions(-I/usr/lib/x86_64-linux-gnu/glib-2.0/include)
add_definitions(-I/usr/include/libxml2)
set(SOURCE_FILES main.c)
add_executable(testes ${SOURCE_FILES})
target_link_libraries(testes pthread glib-2.0 gobject-2.0 gda-5.0)
My environment:
OS Xubuntu 16.04 64 bits
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)
$ pkg-config glib-2.0 libgda-5.0 --modversion
2.48.1
5.2.4
Thank you!
