But, luckily, 'cvs diff -U1' can come to the rescue. Do:
$ cvs diff -U1 some-directory-with-modified-files > my-changes
Now open my-changes in a text editor. You can remove any section from a
'@@' to another '@@' without corrupting the diff. The idea is to remove
all sections that correspond to 'real' changes, while leaving all the
sections that correspond to formatting-only changes. For example:

The first section is just a white space change. You want to leave that
one in. The second section is a 'real' change (it's actually bogus, in
that the original code was correct, but I had to change something in order
to make this a good example). And the last section is another
formatting-only change, which you want to remove. You end up with:

Note how the second modified section was removed from the file. Now you
can 'undo' all the changes left in the my-changes file (the changes
corresponding to formatting only) with the slightly-magic command:
$ POSIXLY_CORRECT=1 patch -p0 -R < my-changes
Now a cvs-diff should only show 'good' changes. Of course sometimes
your good and bad changes are too close together and you can't separate
them cleanly using the above technique, but it should get rid of the large
portion, leaving less for you to manually clean. Keep using 'cvs diff'
until the only changes shown are 'good' functional (not 'bad' formatting)
changes. Extra hint --- if you keep your 'my-changes' file, you can
submit it separately as a formatting-only patch -- or reapply it once your
'real code' patch has been accepted with:
$ POSIXLY_CORRECT=1 patch -p0 < my-changes
Hope this helps you clean up your patches for submission!
--scott
[reading the info pages for diff and patch will help a lot if this
step-by-step seemed overly magical. =) I believe that if your version
of 'cvs' is new enough (1.11.2 works for me) you don't need the
POSIXLY_CORRECT=1 bit on the patch command. But old cvs servers (1.10.2,
for example) leave off the directory part of the file name on the '---'
and '+++' lines, confusing patch unless you use POSIXLY_CORRECT.]

See http://java.sun.com/products/jdk/1.1/docs/guide/serialization/spec/class.doc.html#4100 for the exact details of the serialVersionUID computation. Note that it includes the names of all non-private fields and methods, so that classpath's implementation will likely yield a different serialVersionUID. However, assuming that the method and field names don't change from platform and platform (which seems extremely reasonable), the serialVersionUID should be the same.

Initialization and ProtectionDomains.
The recent change to java.lang.String (aug 13, v1.50) add a call to
Character.zeroBasedStringValue() which (inadvertently?) makes
java.lang.Character part of the "CORE CLASS" initializers (because String
is a core class, and the static initializer of String invokes a method in
Character, causing the initialization of Character). Character should
be either marked as a CORE CLASS or the shared method should be moved
to java.lang.String.
If Character remains a core class, it invokes
VMClassLoader.getPrimitiveClass() which will initialize java.lang.Class,
whose static initializer references java.security.ProtectionDomain.
The static initializer for ProtectionDomain inexplicably invokes
System.getProperty(), which will lead to a null pointer exception, because
the properties have not yet been initialized. (String needs to be
initialized before Runtime.insertSystemProperties can be run, and we've
gotten to ProtectionDomain by *trying* to initialize String).
The appended patch removes the unnecessary static initializer of
ProtectionDomain, which helps somewhat. IMO, the other fix should be to
move the zeroBasedStringValue() method to java.lang.String.

java.lang.VMObject.getClass() should be removed.
The VMObject.getClass() method should be removed, as it is not VM-specific: it is implemented in terms of JNI calls (and gcj has its own way of doing this in CNI). Furthermore, VMObject.getClass() is never called anywhere in classpath, in particular not from Object.getClass(). So I think VMObject.getClass() should just be removed. --scott milita Moscow cracking Rijndael Mk 48 ASW $400 million in gold bullion Secretary plastique COBRA JANE SEAL Team 6 early warning Hager WTO ( http://cscott.net/ ) ___ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath
bug in gnu.vm.stack.StackFrame
The gnu/vm/stack/StackFrame class has the following bit of code:
private StackFrame(Object obj, Method method, int lineNum, String filename) {
this.caller = caller;
}
Note that 'caller' is not an argument of the constructor. So the first
statement of the constructor is effectively a no-op, equivalent to
this.caller = this.caller
Oops!
I'm guessing 'StackFrame caller' should be an argument to the constructor.
Also, as the StackFrame is a linked list, I'm guessing the fact that
the gnu.vm.stack.StackTrace class uses an *array* of StackFrames
is a bug, or at least redundant.

The bytecode compiler cannot do this, because the class file format does not provide a means to encode String constants with non-zero offsets in the constant pool. But the JVM and a native compiler might well do so; this is the expected behavior of C compilers, for example: they attempt to reduce the storage space needed to store the strings "bar" and "foobar" by using a pointer to the middle of "foobar" to represent "bar". The obvious Java parallel is to share the character arrays for the Strings representing "foobar" and "bar" and just change the offset in the String object.

However it's useful to note that Sun has a version of the Swing library that worked with 1.1 JDKs on their website. Although this is non-free, it could allow you to use your application with classpath's AWT implementation until classpath (starts and then) completes its Swing implementation. As this implementation of Swing is built upon AWT interfaces, this would hopefully help us iron out the bugs in our (at the moment barely working) AWT implementation. --scott chemical agent fissionable cryptographic Morwenstow Saddam Hussein operation Milosevic Iraq ammunition UKUSA Qaddafi Pakistan security ( http://cscott.net/ ) ___ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath

Changes for "refactoring" purposes are likely to be greeted with much more skepticism than performance improvements, which are likely to be greeted with more skepticism than obvious bug-fixes, which are still accepted less readily than simple comment or javadoc additions. It might be best to start with the simple obvious stuff and work up to the more complicated changes. - I was very glad to see that each change in the diff apparently had a changelog entry. But the diff itself was not a 'unified' diff (the -u option) which I believe is the standard. I'm very used to reading unified diff patches, but the 'copied context' format took a little more effort to decipher. [Also, I don't know if there's an automatic means to import changelog information included in-line with the diff.] - There should be changelog information associated with the new files, as well, no? - finally, I believe that classpath requires a formal copyright assignment in order for them to incorporate these changes; especially the additions of entire files.

It's a *research* Java-to-native compiler. "Research" means that it isn't fast, doesn't care about separate compilation, and it's written to be a good platform for investigating Java *analysis* --- not necessarily to be the most practical day-to-day compiler. But, as the fate of all Java research projects, it needs a runtime and class library implementation to be useful. Currently it is built around the bytecode of Sun's JDK 1.1.x class libraries, with lots of hacks around the edges to make most java 1.2 apps run. But Sun's license doesn't let us redistribute the class libraries (we have to make people hunt them down on Sun's site and extract them themselves), which is a pain in the neck. > There probably were potential circular dependencies, but I think the old > kissme code was capable of locking up even without them.

What I was saying, in effect, was that duplicate array bounds checks should be optimized away, *if the compiler can determine that they are, in fact, duplicate*. Using the try-catch construct obscures this fact, so it makes it harder for the compiler to Do The Right Thing. Ideally, a compiler would a) inline String.charAt(), b) remove the check from the inlined String.charAt() since it was dominated by a similar check, and c) then remove the second bounds check in decode, for the same reason as b). I'm pretty sure the MIT FLEX compiler can do this, for example. There are so many duplicate checks implicit in the java semantics that most compilers would/should optimize them away. --scott PLO AP Cocaine Boston Hussein Albanian assassination politics RNC munitions Kojarena plastique Serbian Rule Psix President planning ( http://lesser-magoo.lcs.mit.edu/~cananian ) ___ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath

For what it's worth: often adding explicit bounds checks will enable the compiler to create faster code (by hoisting these checks, and others which are implicit in the java semantics, out of the loop). I'm not sure which/any of the existing Java compilers are smart enough to do this, but they all will be, eventually. The try-catch block technique is sometimes faster for NullPointer exceptions (because the exception handling is wrapped around the native hardware memory protection mechanisms, and thus no hardware instructions are required to do the checks in the common case), but I can't imagine any case where the try-catch would be faster for array-bounds (okay, there are some w/in *imagination*, but...). In most cases, you'd be doing the same array-bounds tests in hardware as in the explicit case, but then you'd have to create the exception object and throw it, only to be caught, rebuilt as another exception object, and rethrown.

There are Attributes defined in the Classfile format which (ought to)
provide this information for inner classes. Presumably the information in
the Attribute gets squirreled away somewhere for the implementations of
these methods to use.
I ignore these attributes in my java runtime, because i'm lazy.

you actually have to do this the other way 'round (maintain the number
negative as you build it, then negate it if the number was really
positive) because the negative range of the integer types is larger than
the positive range. Try parsing Integer.MIN_VALUE, for example: your code
will break.

the compiler should optimize these bytecodes away if the ./configure

someone can show that the compiler does *not* in fact do this

i think it's a good idea.

That's "one per ClassLoader per *primitive* type, more likely, which means
9 times per ClassLoader, which (considering the number of ClassLoaders in
a typical program) is not very often at all.

sorry, that *was* a bit inflammatory. I meant something closer to, "VMs
which will execute classpath as compiled to bytecode by sun's java
compiler and jikes" -- which, of course, compile 'boolean.class' as
'Boolean.TYPE'. GCJ does the compilation of classpath itself, and so it
doesn't ever need to execute classpath as sun's compiler would render it.
C'mon that *does* make GCJ 'different' from the rest of the VMs...

okay, how about:
class Boolean {
Class TYPE = VMLoader.BooleanTYPE;
}
with VMLoader on gcj being something like:
class VMLoader {
Class BooleanTYPE = boolean.class;
}
and VMLoader on sane VMs being:
class VMLoader {
Class BooleanTYPE = VMLoader.loadPrimitiveClass("boolean");
}
This has a total time over head of *nine loads*, executed *once* at the
beginning of the program. Total space overhead is *nine words* (eleven,
if you need a header for VMLoader). I think even your 28K system can get
by with this.
I don't see why portability is so difficult.

I just verified that javac compiles this in the same way.
Foo.java:
public class foo {
Class field = boolean.class;
}
Compiling:
% java -version
java version "1.3.0"
% javac -d . -g foo.java
Disassembling:
% javap -c foo
Compiled from foo.java
public class foo extends java.lang.Object {
java.lang.Class field;
public foo();
}
Method foo()
0 aload_0
1 invokespecial #1
4 aload_0
5 getstatic #2
8 putfield #3
11 return
-
It's hard to tell that pc 5 is in fact a load from Boolean.TYPE (with
type java.lang.Class); my harpoon compiler loading this bytecode is more
clear:
% java harpoon.Main.Main foo
Codeview "bytecode" for public foo():
#0/foo.java:1 - aload_0 lv_0
#1/foo.java:1 - invokespecial public java.lang.Object()
#2/foo.java:2 - aload_0 lv_0
#3/foo.java:2 - getstatic public static final java.lang.Class java.lang.Boolean.TYPE
#4/foo.java:2 - putfield java.lang.Class foo.field
#5/foo.java:1 - return
Hope this makes clear why the Classpath code is written as it is.

With jikes, at least, this actually compiles to:
public static final Class TYPE = Boolean.TYPE;
which is probably not what you meant.

Fields marked transient are *defined* to be reset to zero after
deserialization. Use 0 as your non-cached value; the only "harm" will be
that hashCode will have the same performance as the non-caching version
for Double(0) -- it's still better than not caching at all.

that's no excuse. I hereby volunteer to host a web page on my machine
here at MIT (a few floors up from GNU) with a server-side include that
will dynamically fetch the current document from the GNU ftp servers.
Maybe it won't be as robust as the global mirroring system, but the fact
that we can't do it *everywhere* doesn't mean that we can't (or
shouldn't) do it *somewhere*.
For extra credit, I'll even program a dynamic fetch from a randomly chosen
GNU ftp site, in the off chance that millions of developers want to
simultanously sign FSF release forms.

just a javap issue. according to the java vm spec (section 4.1):
"An interface is implicitly abstract (2.13.1); its ACC_ABSTRACT flag
must be set."
If 1.1 compilers were generating interfaces without setting ACC_ABSTRACT,
they were in error.

for what it's worth, i've benchmarked "semi-precise" garbage collection
(which you are calling "mostly-precise") compared to standard
"fully-conservative" (i.e. "not-at-all precise") garbage collection using
the B-D-W collector (which gcj uses) on the FLEX compiler project and
found very little (about 2%) performance improvement. Precise garbage
collection strategies are capable of much better; within a month I hope to
have exact numbers here, for our compiler.

you can actually embed precise garbage collection even without the table
output; i'm hoping to have a paper Real Soon Now describing the technique
and the performance issues.

I can think of some appropriate strategies here, but I'm afraid it would
tend to make the CNI code *look* like JNI code, even if the performance
was CNI-like. I've heard some arguments on this list that such a solution
would be unacceptable ("JNI is too noisy", etc.).

really? I've got 172,301 lines of java source (in 877 files) which I
compile by doing *exactly that*. Takes jikes about 10 seconds.
I don't think you should discard this alternative. Maybe it's not the
only way, but it's effective for bootstrapping. And jikes, I believe,
lets you put the list of source files in a separate file so that
command-line limitations are not an issue, either.

[De-lurking] I'm the primary author of the MIT FLEX compiler
infrastructure (http://www.flexc.lcs.mit.edu/Harpoon), and I'll pipe in my
two cents and mention that pure-C-plus-JNI really is the way to go if you
want classpath adopted any- and every- where. JNI really *was*
well-thought out with respect to gc-issues, and if you're doing *any*
sophisticated OO tricks in your compiler, you *need* the
implementation-independence which JNI gives you. I've been trying to port
FLEX over to Classpath from our current "sun jdk1.1"-based runtime for
quite a while (never quite enough time); CNI independence is really a
necessity to allow such cross-pollination to occur.

I've got a GPL'ed project that uses 'only the Collections' part of JDK1.2, and it would enable me to support it on JDK1.1 without using a collection of Sun's code which I can't distribute.

New JVM port of Classpath
I've just begun work on fitting Classpath together with the FLEX j*va-to-native compiler infrastructure (http://flex-compiler.lcs.mit.edu/Harpoon). This is just a quick note to let the list know what I'm up to; I've gotten only as far as autoconf/automake support for the new VM so far. --s ASW FBI Iraq operative chemical agent Albanian Milosevic Shoal Bay KGB General C4 SLBM Japan World Trade Center North Korea Marxist Noriega ( http://lesser-magoo.lcs.mit.edu/~cananian )
