/* DDE Notes
 *
 * This section describes the Win32 DDE service implementation for
 * Mozilla.  DDE is used on Win32 platforms to communicate between
 * separate instances of mozilla.exe (or other Mozilla-based
 * executables), or, between the Win32 desktop shell and Mozilla.
 *
 * The first instance of Mozilla will become the "server" and
 * subsequent executables (and the shell) will use DDE to send
 * requests to that process.  The requests are DDE "execute" requests
 * that pass the command line arguments.
 *
 * Mozilla registers the DDE application "Mozilla" and currently
 * supports only the "WWW_OpenURL" topic.  This should be reasonably
 * compatible with applications that interfaced with Netscape
 * Communicator (and its predecessors?).  Note that even that topic
 * may not be supported in a compatible fashion as the command-line
 * options for Mozilla are different than for Communiator.
 *
 * It is imperative that at most one instance of Mozilla execute in
 * "server mode" at any one time.  The "native app support" in Mozilla
 * on Win32 ensures that only the server process performs XPCOM
 * initialization (that is not required for subsequent client processes
 * to communicate with the server process).
 *
 * To guarantee that only one server starts up, a Win32 "mutex" is used
 * to ensure only one process executes the server-detection code.  That
 * code consists of initializing DDE and doing a DdeConnect to Mozilla's
 * application/topic.  If that connection succeeds, then a server process
 * must be running already.
 *
 * Otherwise, no server has started.  In that case, the current process
 * calls DdeNameService to register that application/topic.  Only at that
 * point does the mutex get released.
 *
 * There are a couple of subtleties that one should be aware of:
 *
 * 1. It is imperative that DdeInitialize be called only after the mutex
 *    lock has been obtained.  The reason is that at shutdown, DDE
 *    notifications go out to all initialized DDE processes.  Thus, if
 *    the mutex is owned by a terminating intance of Mozilla, then
 *    calling DdeInitialize and then WaitForSingleObject will cause the
 *    DdeUninitialize from the terminating process to "hang" until the
 *    process waiting for the mutex times out (and can then service the
 *    notification that the DDE server is terminating).  So, don't mess
 *    with the sequence of things in the startup/shutdown logic.
 *
 * 2. All mutex requests are made with a reasonably long timeout value and
 *    are designed to "fail safe" (i.e., a timeout is treated as failure).
 *
 * 3. An attempt has been made to minimize the degree to which the main
 *    Mozilla application logic needs to be aware of the DDE mechanisms
 *    implemented herein.  As a result, this module surfaces a very
 *    large-grained interface, consisting of simple start/stop methods.
 *    As a consequence, details of certain scenarios can be "lost."
 *    Particularly, incoming DDE requests can arrive after this module
 *    initiates the DDE server, but before Mozilla is initialized to the
 *    point where those requests can be serviced (e.g., open a browser
 *    window to a particular URL).  Since the client process sends the
 *    request early on, it may not be prepared to respond to that error.
 *    Thus, such situations may fail silently.  The design goal is that
 *    they fail harmlessly.  Refinements on this point will be made as
 *    details emerge (and time permits).
 */

/* Update 2001 March
 *
 * A significant DDE bug in Windows is causing Mozilla to get wedged at
 * startup.  This is detailed in Bugzill bug 53952
 * (http://bugzilla.mozilla.org/show_bug.cgi?id=53952).
 *
 * To resolve this, we are using a new strategy:
 *   o Use a "message window" to detect that Mozilla is already running and
 *     to pass requests from a second instance back to the first;
 *   o Run only as a "DDE server" (not as DDE client); this avoids the
 *     problematic call to DDEConnect().
 *
 * We still use the mutex semaphore to protect the code that detects
 * whether Mozilla is already running.
