After getting libcurl to compile for Symbian - Nokia 5th edition SDK
1,0 - I began implementing a protocol that sits on top of HTTP/HTTPS.
Although simple GETs and POSTs work fine. A GET with my own headers
supplied crashes with a memory overrun down in curlib. Perhaps I'm
doing something wrong but I've narrowed the code down as much as I can
and its just not doing that much. Here it is :
void testGetWithHeaders(char* url)
{
CURL *curl;
CURLcode curl_result;
curl = curl_easy_init();
if (curl)
{
curl_easy_setopt(curl, CURLOPT_URL, url);
struct curl_slist *headers=NULL;
headers = curl_slist_append(headers, "x-mm-clientid: nmm:[email protected]
");
headers = curl_slist_append(headers, "x-mm-commandid: 2");
headers = curl_slist_append(headers, "x-mm-cookie:
NIC=NIC-7668-27");
headers = curl_slist_append(headers, "x-mm-cookie:
PIC=PIC-7668-28");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_result = curl_easy_perform(curl);
curl_easy_cleanup(curl);
if (curl_result == CURLE_OK)
{
std::cout << "OK!" << std::endl;
}
else
{
// something went wrong - error code is in curl_result
std::cout << "libcurl error code #" << curl_result <<
std::endl;
}
}
}
The crash occurs in curl_easy_perform. It looks like after the GET
returns with the data (the server sends back HTTP/1.1 200 OK), the
curlib attempts to write a giant amount of data back. This is because
data->req.upload_present is set to -103. That value gets passed in as
size_t len in :
CURLcode Curl_write(struct connectdata *conn, curl_socket_t sockfd,
const void *mem, size_t len, ssize_t *written)
and becomes 4294967188.
If anyone has suggestions to track this down further or some idea of
something stupid that I'm doing they'd be appreciated. thanks.
