/* 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.
