This creates a X connection, a GLX context, calls glGetString, and writes that +// to the 'write' end of the pipe. + +#include <cstdio> +#include <cstdlib> +#include <unistd.h> +#include <dlfcn.h> +#include "nscore.h" +#include <fcntl.h> +#include "stdint.h" + +#if MOZ_WIDGET_GTK == 2 +#include <glib.h> +#endif + +#ifdef __SUNPRO_CC +#include <stdio.h> +#endif + +#include "X11/Xlib.h" +#include "X11/Xutil.h" + +#include "mozilla/Unused.h" + +// stuff from glx.h +typedef struct __GLXcontextRec *GLXContext; +typedef XID GLXPixmap; +typedef XID GLXDrawable; +/* GLX 1.3 and later */ +typedef struct __GLXFBConfigRec *GLXFBConfig; +typedef XID GLXFBConfigID; +typedef XID GLXContextID; +typedef XID GLXWindow; +typedef XID GLXPbuffer; +#define GLX_RGBA 4 +#define GLX_RED_SIZE 8 +#define GLX_GREEN_SIZE 9 +#define GLX_BLUE_SIZE 10 + +// stuff from gl.h +typedef uint8_t GLubyte; +typedef uint32_t GLenum; +#define GL_VENDOR 0x1F00 +#define GL_RENDERER 0x1F01 +#define GL_VERSION 0x1F02 + +namespace mozilla { +namespace widget { +// the read end of the pipe, which will be used by GfxInfo +extern int glxtest_pipe; +// the PID of the glxtest process, to pass to waitpid() +extern pid_t glxtest_pid; +} +} + +// the write end of the pipe, which we're going to write to +static int write_end_of_the_pipe = -1; + +#if MOZ_WIDGET_GTK == 2 +static int gtk_write_end_of_the_pipe = -1; +int gtk_read_end_of_the_pipe = -1; +#endif + +// C++ standard collides with C standard in that it doesn't allow casting void* to function pointer types. +// So the work-around is to convert first to size_t. +// http://www.trilithium.com/johan/2004/12/problem-with-dlsym/ +template<typename func_ptr_type> +static func_ptr_type cast(void *ptr) +{ + return reinterpret_cast<func_ptr_type>( + reinterpret_cast<size_t>(ptr) + ); +} + +static void fatal_error(const char *str) +{ + mozilla::Unused << write(write_end_of_the_pipe, str, strlen(str)); + mozilla::Unused << write(write_end_of_the_pipe, "\n", 1); + _exit(EXIT_FAILURE); +} + +static int +x_error_handler(Display *, XErrorEvent *ev) +{ + enum { bufsize = 1024 }; + char buf[bufsize]; + int length = snprintf(buf, bufsize, + "X error occurred in GLX probe, error_code=%d, request_code=%d, minor_code=%d\n", + ev->error_code, + ev->request_code, + ev->minor_code); + mozilla::Unused << write(write_end_of_the_pipe, buf, length); + _exit(EXIT_FAILURE); + return 0; +} + + +// glxtest is declared inside extern "C" so that the name is not mangled. +// The name is used in build/valgrind/x86_64-redhat-linux-gnu.sup to suppress +// memory leak errors because we run it inside a short lived fork and we don't +// care about leaking memory +extern "C" { + +void glxtest() +{ + // we want to redirect to /dev/null stdout, stderr, and while we're at it, + // any PR logging file descriptors.

In addition, it serves as a + * query as to whether the application should continue to + * run. + * + * If the returned boolean result is PR_FALSE, then the + * application should exit without further processing. In + * such cases, the returned nsresult indicates whether the + * reason to exit is due to an error or not. + * + * Win32 Note: In the case of starting a second instance + * of this executable, this function will return + * PR_FALSE and nsresult==NS_OK.

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. + */ + +/* Update 2007 January + * + * A change in behavior was implemented in July 2004 which made the + * application on launch to add and on quit to remove the ddexec registry key. + * See bug 246078. + * Windows Vista has changed the methods used to set an application as default + * and the new methods are incompatible with removing the ddeexec registry key. + * See bug 353089. + * + * OS DDE Sequence: + * 1.

If it is registered the OS sends a DDE request with the WWW_OpenURL topic + * and the params as specified in the default value of the ddeexec registry + * key for the verb (e.g. open). + * 3. If it isn't registered the OS launches the executable defined in the + * verb's (e.g. open) command registry key. + * 4. If the ifexec registry key is not present the OS sends a DDE request with + * the WWW_OpenURL topic and the params as specified in the default value of + * the ddeexec registry key for the verb (e.g. open). + * 5. If the ifexec registry key is present the OS sends a DDE request with the + * WWW_OpenURL topic and the params as specified in the ifexec registry key + * for the verb (e.g. open). + * + * Application DDE Sequence: + * 1. If the application is running a DDE request is received with the + * WWW_OpenURL topic and the params as specified in the default value of the + * ddeexec registry key (e.g. "%1",,0,0,,,, where '%1' is the url to open) + * for the verb (e.g. open). + * 2. If the application is not running it is launched with the --requestPending + * and the --url argument. + * 2.1 If the application does not need to restart and the --requestPending + * argument is present the accompanying url will not be used. Instead the + * application will wait for the DDE message to open the url. + * 2.2 If the application needs to restart the --requestPending argument is + * removed from the arguments used to restart the application and the url + * will be handled normally. + * + * Note: Due to a bug in IE the ifexec key should not be used (see bug 355650). + */ + +class nsNativeAppSupportWin : public nsNativeAppSupportBase, + public nsIObserver +{ +public: + NS_DECL_NSIOBSERVER + NS_DECL_ISUPPORTS_INHERITED + + // Overrides of base implementation. + NS_IMETHOD Start( bool *aResult ); + NS_IMETHOD Stop( bool *aResult ); + NS_IMETHOD Quit(); + NS_IMETHOD Enable(); + // The "old" Start method (renamed). + NS_IMETHOD StartDDE(); + // Utility function to handle a Win32-specific command line + // option: "--console", which dynamically creates a Windows + // console. + void CheckConsole(); + +private: + ~nsNativeAppSupportWin() {} + static void HandleCommandLine(const char* aCmdLineString, nsIFile* aWorkingDir, uint32_t aState); + static HDDEDATA CALLBACK HandleDDENotification( UINT uType, + UINT uFmt, + HCONV hconv, + HSZ hsz1, + HSZ hsz2, + HDDEDATA hdata, + ULONG_PTR dwData1, + ULONG_PTR dwData2 ); + static void ParseDDEArg( HSZ args, int index, nsString& string); + static void ParseDDEArg( const WCHAR* args, int index, nsString& aString); + static HDDEDATA CreateDDEData( DWORD value ); + static HDDEDATA CreateDDEData( LPBYTE value, DWORD len ); + static bool InitTopicStrings(); + static int FindTopic( HSZ topic ); + static void ActivateLastWindow(); + static nsresult OpenWindow( const char *urlstr, const char *args ); + static nsresult OpenBrowserWindow(); + static void SetupSysTrayIcon(); + static void RemoveSysTrayIcon(); + + static int mConversations; + enum { + topicOpenURL, + topicActivate, + topicCancelProgress, + topicVersion, + topicRegisterViewer, + topicUnRegisterViewer, + topicGetWindowInfo, + // Note: Insert new values above this line!!!!! + topicCount // Count of the number of real topics + }; + static HSZ mApplication, mTopics[ topicCount ]; + static DWORD mInstance; + static bool mCanHandleRequests; + static char16_t mMutexName[]; + friend struct MessageWindow; +}; // nsNativeAppSupportWin + +NS_INTERFACE_MAP_BEGIN(nsNativeAppSupportWin) + NS_INTERFACE_MAP_ENTRY(nsIObserver) +NS_INTERFACE_MAP_END_INHERITING(nsNativeAppSupportBase) + +NS_IMPL_ADDREF_INHERITED(nsNativeAppSupportWin, nsNativeAppSupportBase) +NS_IMPL_RELEASE_INHERITED(nsNativeAppSupportWin, nsNativeAppSupportBase) + +void +UseParentConsole() +{ + // Try to attach console to the parent process. + // It will succeed when the parent process is a command line, + // so that stdio will be displayed in it. + if (AttachConsole(ATTACH_PARENT_PROCESS)) { + // Change std handles to refer to new console handles. + // Before doing so, ensure that stdout/stderr haven't been + // redirected to a valid file. + // The return value for _fileno(<a std handle>) for GUI apps was changed over. + // Until VC7, it was -1.
