September 2000. It will run, but without bookmarks.
The changes consist of the following kinds of changes:
Changes to method signatures for methods implemented by webclient.
Changes to string functions.
Changes to account for the demise of PROGIDS in favor of ContractIDs

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 fix has been tested on win32, solaris, and linux.

* How to create a new listener type on the native side: <P>
* 1. add an entry in the gSupportedListenerInterfaces array defined in

Added class WCEventListenerWrapper:

* multiple Webclient event listener types. <P>
* This is simply a "struct" type class that encapsulates a listener

* WebclientEventListener, and not a WebclientEventListener subclass. <P>
* @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>
* The vector is a vector of WCEventListenerWrapper instances. In run()
* these are unpacked and sent to nativeAddListener like this:
* nativeAddListener(nativeWebShell,tempListener.listener,
* tempListener.listenerClassName); <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
docShell as a listener. The solution was to call

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.

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

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();
}
}
}

This change enables the current webclient API to be called from native
code.
It adds makefile and conditional compilation logic.
If the user defines BAL_INTERFACE in their environment before building
webclient, -DBAL_INTERFACE is added to LCFLAGS. This causes code in
jni_util_export.cpp to behave differently due to the conditional
compilation logic.
I've broken out the 8 functions that are necessary to call into the
Webclient JNI methods into jni_util_export.{h,cpp}.
I've created a new pair of files, bal_util.{h,cpp} that contain function
declarations and definitions that are used when src_moz is built with
BAL_INTERFACE. bal_util.obj is not built, nor added to webclient.dll if
building without BAL_INTERFACE.
See the page
http://www.mozilla.org/projects/blackwood/webclient/design/uno-transition.html
for a design document description of these changes.

This set of changes replaces all occurrences of
env->Func(args...)
with
::util_Func(env, args...)
Except of course, for the implementations of the above mentioned
::util_Func() functions.
This is done to allow the JNI functions to be called from a non JNI
context, such as UNO.
also modifies EmbeddedMozilla so this code is exercised.
I have changed EmbeddedMozilla to be a stub-like class that simply
displays a Frame with a single Button, titled "New Window". Pressing
this button causes an EMWindow to be created and displayed. EMWindow is
basically the former EmbeddedMozilla renamed, with modifications to the
WindowListener implementation to call the BrowserControl deallocation
method.
I've added a delete() method to ImplObect:
* I know Java has automatic garbage collection and all, but explicitly
* adding a delete method helps the gc algorithm out. <P>
* Subclasses should override this and call super.delete() at the end of
* their overridden delete() method.
* @see org.mozilla.webclient.wrapper_native.ImplObjectNative#delete
and ImplObjectNative:
* Note how we call super.delete() at the end. THIS IS VERY IMPORTANT. <P>
* Also, note how we don't de-allocate nativeWebShell, that is done in
* the class that owns the nativeWebShell reference, WindowControlImpl.
* ImplObjectNative subclasses that further override delete() are <P>
<CODE><PRE>
BookmarksImpl.java
EventRegistrationImpl.java
NativeEventThread.java
WindowControlImpl.java
</PRE><CODE> <P>
* All other ImplObject subclasses don't have any local Ivars and thus
* don't need to override delete().
I've added a delete() method to BrowserControlImpl:
* Called from BrowserControlFactory.deleteBrowserControl() <P>
* The order of deletion of objects is very important! <P>
* We don't allow deletion if the Canvas is showing. <P>
In BrowserControlImpl's delete(), the important delete()s is for
WindowControlImpl:
* First, we delete our eventThread, which causes the eventThread to
* stop running. Then we call nativeDestroyInitContext(), which
* deallocates native resources for this window.
As stated above, NativeEventThread.delete() is called:
* This is a very delicate method, and possibly subject to race
* condition problems. To combat this, our first step is to set our
* browserControlCanvas to null, within a synchronized block which
* synchronizes on the same object used in the run() method's event
* loop. By setting the browserControlCanvas ivar to null, we cause the
* run method to return.
After all of this deleting, we return from
BrowserControlFactory.delete().

Make BrowserControl vend a Canvas instead of
BrowserControlCanvas vending a BrowserControl.
This change has nothing to do with mozilla. It's pure java.
* This change fixes
http://bugzilla.mozilla.org/show_bug.cgi?id=15793 which caused one
to have to copy the component.reg and components directory. It
also causes webclient to do autoregistration. It also adds a
debugging method to BrowserControlMozillaShim.java
nativeDebugBreak().
This changes makes webclient depend on having mozilla sources from
10/5/99 or later.

This fix enables the Tasks->Java Console menu item to show the Java
Console provided by the JRE plugin if it is installed.
It also exposes nsIJVMManager as a full XPIDL citizen, with the progid
component://netscape/oji/jvm-mgr. see modules/oji/public/nsIJVMManager.idl
for the methods that can be called.
