/* 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.
