Bug 225389 – [SOUP] Wrong cookie timestamp in case of long expire time

• Component: WebKitGTK
• Status: RESOLVED FIXED

Assume I have a cookie file cookie.txt

#HttpOnly_localhost	FALSE	/	FALSE	2682374400	prov	123	None

Which is specifies date 2055-01-01:00:00:00

When I try to access this cookie through:

  GFile *cookie_path =
    g_file_new_build_filename (dirpath, "cookies.txt", NULL);
  webkit_cookie_manager_set_persistent_storage
    (cm, g_file_peek_path (cookie_path), WEBKIT_COOKIE_PERSISTENT_STORAGE_TEXT);
...

gboolean
inspect_cookies(WebKitCookieManager *cm) {
  webkit_cookie_manager_get_cookies
    (cm, "http://localhost/", NULL,
     inspect_localhost_cookies_cb,
     NULL);
  return FALSE;
}



void
inspect_localhost_cookies_cb(GObject *source_object, GAsyncResult *res,
			     gpointer user_data)
{
  GError *error;
  WebKitCookieManager *cookie_manager = WEBKIT_COOKIE_MANAGER(source_object);
  error = NULL;
  GList *gl =
    webkit_cookie_manager_get_cookies_finish (cookie_manager, res, &error);
  if (error) {
    g_warning("inspect cookies cb: failed: %s", error->message ?: "");
    return;
  }

  while (gl) {
    g_assert(gl->data);
    SoupCookie *soup_cookie = gl->data;
    g_message("COOKIE ==> %s", soup_cookie_to_set_cookie_header(soup_cookie));
    gl = gl->next;
  }
}


I get a message which shows
** Message: 15:11:42.077: COOKIE ==> prov=123; expires=Fri, 01-Jan-2055 00:00:-8 GMT; path=/; domain=localhost; HttpOnly

This indicates that the seconds field now stores a negative integer.

In practice this triggers a critical in glib

I'm noticing this since 2.32.0. Do others see this or should i suspect another gcc bug

I can reproduce with libsoup2, but it's also failing in libsoup3 in a different way. It's a WebKit bug in any case. I'll submit a patch.
