https server - memory leaks

[Bernhard Schuster <schuster bernhard gmail com>]

I am running a decent HTTP server which fulfills just one specific task. I trimed (almost - setup stuff) all memory leaks so far, except for one.

Massif/Valgrind tell me that it is part of libgiognutls.so/libgnutls.so (g_memdup -> g_bytes_new). I had a very brief look at the code but could not spot anything suspicous in gtls{server,}connection.[ch] - but as said I only had a very brief look.

Also when I just do a few requests and set breakpoints on g_bytes_new and g_bytes_unref their count is equal, and g_memdup occurs by far too frequently to set breakpoints on.

I attached a screenshot of massif, showing the increased memory usage over time (and requests) altough the requests is pretty much just a nop.

The requests are currently issued via curl

curl -k -v -i -X PUT -d "bogus content" -u "foo:bar" --digest "https://127.0.0.1:1234/

// the soup server callback looks like this

static void

server_callback (SoupServer *server,

                 SoupMessage *msg,

                 const char *path,

                 GHashTable *query,

                 SoupClientContext *client,

                 gpointer user_data)

{

 echo_debug ("brute force memleak search...");

 soup_message_set_status (msg, SOUP_STATUS_SERVICE_UNAVAILABLE /* 503 */);

 return;

}

// server setup looks like (which I previously already posted)

  server = soup_server_new (SOUP_SERVER_SERVER_HEADER, "fooifier",

                         SOUP_SERVER_TLS_CERTIFICATE, tlscert,

                         SOUP_SERVER_PORT, 1234,

                         NULL);

  authdomain = soup_auth_domain_digest_new (

                   SOUP_AUTH_DOMAIN_REALM, REALM,

                SOUP_AUTH_DOMAIN_DIGEST_AUTH_CALLBACK, auth_digest_callback,

                SOUP_AUTH_DOMAIN_DIGEST_AUTH_DATA, map_user_to_digest,

                NULL);

  soup_auth_domain_add_path (authdomain, "/");

  soup_server_add_auth_domain (server, SOUP_AUTH_DOMAIN (authdomain));

  g_object_unref (authdomain);

  soup_server_add_handler (server,

                        NULL /* NULL == default handler */,

                        (SoupServerCallback)server_callback,

                        NULL, NULL);

  g_assert (soup_server_is_https (server));

  soup_server_run_async (server);

Any help, pointer or hint is highly appreciated.
