This checkin migrates javaDOM to use the new nsIWebProgressListener
interface, removing its dependency on the now non-existant
nsIDocumentLoaderObserver.
It has only been tested inside webclient. QA needs to do the standalone
javaDOM tests.

This patch allows BlackConnect to build with Forte Compilers. It
fixes some syntactical errors in the xpidl_idl.c and xpidl_java.c
files where C++ style syntax was being used in a C file and some
implicit illegal typecasts were being made.

This fix makes it so bookmarks work with the tip of the branch as of 11/01/00.
This fix removes the necessity to modify xpcom/base/nsDebug.cpp to
remove the thread safety assertions.
This fix primarily does two things:
1. Make nsActionEvents for all bookmarks/rdf actions
2. Remove the synchronized(this.browserControlCanvas.getTreeLock()) call
around nativeProcessEvents() in NativeEventThread.run().

It enables webclient to be built and run under JDK1.1.x. Note that JavaDOM
does not work under jdk1.1.x.
The fix consists of two elements:
On the Java side, replace all JDK1.2 specific calls with JDK1.1.x
equivalents. On the native side use pre-processer macro for
JNI_VERSION, like this:
#ifdef JNI_VERSION_1_2
#ifndef JNI_VERSION
#define JNI_VERSION JNI_VERSION_1_2
#endif
#else
#ifndef JNI_VERSION_1_1
#define JNI_VERSION_1_1 0x00010001
#endif
#ifndef JNI_VERSION
#define JNI_VERSION JNI_VERSION_1_1
#endif
#endif // END: JNI_VERSION_1_2

* This is simply a "struct" type class that encapsulates a listener

* @see org.mozilla.webclient.wrapper_native.NativeEventThread#addListener
Made it so when a java listener is added,
* We create a WCEventListenerWrapper containing the user passed
* DocumentLoadListener, and the string obtained from
* DocumentLoadListener.class.getName();
We then call nativeEventThread.addListener:
* Takes the abstract WebclientEventListener instance and adds it to a
* Vector of listeners to be added. This vector is scanned each time
* around the event loop in run(). <P>

This change creates a new directory, java/webclient/src_share, that
contains the code that will be used in both src_moz and src_ie, and any
other native browser wrapping implementations.
Here are the steps I followed to implement this change.
1. Create a new directory java/webclient/src_share
2. Move all jni_util*.* files from src_moz into src_share
3. Make it so src_share compiles into a new .lib
src_share has no netscape dependencies. Any functionality that
depended on ns dependencies was kept in src_moz. In this case, we
have a function prototype only in src_share, with the implementation
in src_moz. We did this for nsHashtable. The other trick was for
things in WebShellInitContext that had nothing to do with Netscape.
This case was accomodated by creating a new struct, ShareInitContext,
that contains all WebShellInitContext members that have nothing to do
with Netscape. Currently this is just jobject propertiesClass. I
modified the WebShellInitContext struct to contain a ShareContext
struct as its last member. There are two new methods in jni_util.h
that allow for the initialization and deallocation of the members of
the ShareContext struct.
4. Make it so src_moz uses the new .lib to provide the jni_util behavior
a. Create ns_util* files that include ../src_share/jni_util* files
appropriately.
The only tricky part was for things in jni_util.h that

This checkin makes it so CBrowserContainer is properly released. The
problem was that the CBrowserContainer was still registered to the

This checkin mainly does two things:
1. Correctly populates the java.awt.event.MouseEvent subclass with the
correct modifiers, x, y, and clickCount for the mozilla mouse event.
2. Adds a performance optimization: previously, every mouse event was
causing a new instance of java.util.Properties to be created. Now,
only one Properties instance is created per-page, and it is cleared on
each mouse event.
Also, I made the DOMMouseListenerImpl constructor initialize the
refCount to 0. This allows the object to be correctly deleted.

This change adds the following methods:
public static native void org.mozilla.dom.DOMAccessor.initialize();
The implementation of this method is:
JNIEXPORT void JNICALL Java_org_mozilla_dom_DOMAccessor_initialize
(JNIEnv *env, jclass)
{
if (!JavaDOMGlobals::log) {
JavaDOMGlobals::Initialize(env);
}
}
This method is necessary for external clients that want to use JavaDOM,
but don't want to use the nsIDocumentLoaderObserver instance provided by
JavaDOM.
Please see http://bugzilla.mozilla.org/show_bug.cgi?id=41497 for an
additional bug for which there is a workaround.

Added functions for allowing the BAL user to specify functions for
{creating, destroying, setting values into} properties objects.
bug: pressing BACK hangs webclient
Files touched
File: DocumentLoadEvent.java Status: Locally Modified
Made the constants final so they can be used in a
switch statement
File: EMWindow.java Status: Locally Modified
Modified eventDispatched() so it doesn't call any webclient
events. This was causing the hang. Took advantage of
the newly implemented ability to pass a string from the
mozilla event handler into java.
File: DocumentLoaderObserverImpl.cpp Status: Locally Modified
Create a jstring from the url in the OnStartDocumentLoad event.
Pass it on to java.
File: jni_util.cpp Status: Locally Modified
Wrapped JNU_GetEnv in BAL stuff so it works from Star.
File: WebclinetEventListener.java Status: Locally Modified
Added comment to eventDispatched.

Native code changes: This fix eradicates all
occurrences of the following symbols
nsComponentManager nsServiceManeger
And replaces them with their nsI counterparts.
The following ns* classes still are used in
webclient, and no plans exist to replace them
with nsI counterparts: nsresult nsCOMPtr
nsCRT nsnull * nsServiceManager occurrences
were replaced with do_GetService(), using a
PROGID. * nsComponentManager occurrences were replaced with a call on the global class gComponentManager, declared in the new file ns_globals.h, and defined in WrapperFactoryImpl.cpp. ns_globals.h is included in jni_util.h. See the attachment to bug 33099 for ns_globals.h * Added deallocation code to WindowControlImpl.cpp nativeTerminate. I know it doesn't do much, but it's correct. Java code changes: * Added static method BrowserControlFactory.appTerminate(). This method simply calls the existing BrowserControlImpl.appTerminate(), which calls WrapperFactoryImpl.cpp nativeTerminate(). BrowserControlFactory.appTerminate() is called from EmbeddedMozilla's WindowListener, which gets fired when the user signals she wants the app to terminate.

Add an "eventData" argument to WebclientEvent and subclasses.
This argument is sub-event specific. For example, when a user
gets a DocumentLoadEvent, with an event type of
STATUS_URL_LOAD, the eventData is a String containing
the status string from the browser.
Added support for doing this in a BAL context.

Added ability to allow Native webclient client to populate
the listener class hash table and provide an InstanceOf function.
This enables listeners to work for the future.
This change replaces all printfs in src_moz with calls to PR_LOG. No
printfs should appear in src_moz anymore.
You won't see any console output from native code unless you define
NSPR_LOG_MODULES=webclient:3
in your environment. Furthermore, if you want PR_LOG statements in
webclient to go to a file instead, define
WEBCLIENT_LOG_FILE=C:\VALIDDIR\filename.txt
in your environment. This file will get created fresh each time, since
PR_LOG uses fopen(filename, "w").
New Files:
I've created ns_globals.h, included from jni_util.h. ns_globals.h holds
an extern * to a struct used in the PR_LOG calls.
Significant changes:
WrapperFactoryImpl.cpp
nativeAppInitialize(){
Added:
#if DEBUG_RAPTOR_CANVAS
prLogModuleInfo = PR_NewLogModule("webclient");
const char *webclientLogFile = PR_GetEnv("WEBCLIENT_LOG_FILE");
if (nsnull != webclientLogFile) {
PR_SetLogFile(webclientLogFile);
// If this fails, it just goes to stdout/stderr
}
#endif
}
All the other files in this checkin follow the this pattern:
Before checkin:
printf("InitMozillaStuff(%lx): Create the Event Queue for the UI thread...\n",
initContext);
After checkin:
if (prLogModuleInfo) {
PR_LOG(prLogModuleInfo, 3,
("InitMozillaStuff(%lx): Create the Event Queue for the UI thread...\n",
initContext));
}
See http://lxr.mozilla.org/mozilla/source/nsprpub/pr/include/prlog.h#190
for the definition of PR_LOG
NativeEventThread's run() method's infinite loop was implemented. The
loop looks like this:
while (null != this.browserControlCanvas) {
synchronized (this.browserControlCanvas.getTreeLock()) {
nativeProcessEvents(nativeWebShell);
if (null != listenersToAdd && !listenersToAdd.isEmpty()) {
tempEnum = listenersToAdd.elements();
while (tempEnum.hasMoreElements()) {
nativeAddListener(nativeWebShell,
(WebclientEventListener)
tempEnum.nextElement());
}
listenersToAdd.clear();
}
}
}
The problem I was observing was that
nativeProcessEvents(nativeWebShell) would crash due to the fact that
the nativeWebShell, which is actually an WebShellInitContext instance,
had been de-allocated. This de-allocation happens as a result of the
WindowControlImpl.delete() method, which looks like this:
public void delete()
{
Assert.assert(null != eventThread, "eventThread shouldn't be null at delete time");
eventThread.delete();
eventThread = null;
nativeDestroyInitContext(nativeWebShell);
nativeWebShell = -1;
}
nativeDestroyInitContext de-allocates the WebShellInitContextInstance.
You can see that the first thing done is to delete the eventThread().
NativeEventThread.delete() looks like this:
public void delete()
{
// setting this to null causes the run thread to exit
synchronized(this.browserControlCanvas.getTreeLock()) {
browserControlCanvas = null;
}
...
}
If you compare NativeEventThread.delete() with the infinite loop in
NativeEventThread.run(), you'll see that the fact that they both
synchronize on the same object doesn't protect us from the following
case:
NativeEventThread: The infinite loop checks to see if the
browserControlCanvas is null, then does synchronize on
browserControlCanvas.getTreeLock(), then calls processNativeEvents().
meanwhile
WindowControlImpl thread: delete() calls NativeEventThread.delete(),
which does synchronize on browserControlCanvas.getTreeLock().
During NativeEventThread.delete(), synchronized section,
browserControlCanvas is set to null.
NativeEventThread: because the check for null browserControlCanvas
occurrs outside of the synchronized block, it's not recheked, and
thus, the event loop continues to process when it shouldn't.
The fix is to change the event loop to look like this:
while (true) {
synchronized (this.browserControlCanvas.getTreeLock()) {
// this has to be inside the synchronized block!
if (null == this.browserControlCanvas) {
return;
}
nativeProcessEvents(nativeWebShell);
if (null != listenersToAdd && !listenersToAdd.isEmpty()) {
tempEnum = listenersToAdd.elements();
while (tempEnum.hasMoreElements()) {
nativeAddListener(nativeWebShell,
(WebclientEventListener)
tempEnum.nextElement());
}
listenersToAdd.clear();
}
}
