+The Classpath TODO list as of 2000/04/17
+
+-- Modify Classpath build to support libgcj out of the box. Ideally
+ the gcj folks could simply include a stock classpath in one of their
+ distribution subdirectories, have their master configure run a configure
+ on Classpath the appropriate arguments, and everything would build.
+
+-- Integrate packages from libgcj that don't exist in Classpath:
+ o java.util.zip
+ o java.util.jar
+
+-- Modify ClassLoader.getSystemResource() to support loading classes
+ from zip files in the CLASSPATH. This requires java.util.zip to
+ be integrated first. Jar filed can probably be treated as zip
+ files for now.
+
+-- Perform a class by class comparison in packages where both Classpath
+ and libgcj have implementations, and make recommendations for how
+ to merge them and/or which implementations are superior. This has
+ been done for java.net by Gaute Smaaland. See the mail message:
+
+ http://www.mail-archive.com/classpath@gnu.org/msg02135.html
+
+ for his comments. The packages where we need similar work are:
+ o java.io
+ o java.lang
+ o java.lang.reflect
+ o java.text
+ o java.security
+
+ Please keep in mind that Cygnus wishes to continue to use CNI
+ as their preferred native interface. See:
+
+ http://sourceware.cygnus.com/java/papers/cni/t1.html
+
+-- Identify a way to resolve the CNI versus JNI issue. JNI is the
+ Java standard for calling native methods. Classpath needs to support
+ this for standards compliance. CNI is the Cygnus Native Interface,
+ an efficient method for calling native code, but one limited to use
+ with gcj. Cygnus wishes to continue using this because it is more
+ efficient than JNI in their implementation, and uses substantially
+ easier and more readable native code. Proposed solutions to date:
+ o Binary interface
+ o A .in file that is pre-processed through a script to generate
+ CNI or JNI as desired.
+ o Multiple implementations with a compile time switch.
+ o Pre-processing script to convert CNI source to JNI
+
+-- New web site. The Classpath web site at:
+
+ http://www.classpath.org/
+
+ is hideously out of date. Please contact Paul Fisher (rao@gnu.org)
+ and Brian Jones (cbj@gnu.org) if you wish to work in this.
+
+-- Update the GNU Classpath Hacker's Guide. There is a master texinfo
+ file in the doc/ directory in Classpath CVS.
+
+-- Implement a bug tracking system for Classpath.
+
+-- Write Mauve (http://sourceware.cygnus.com/mauve/) tests for those
+ classes that don't have them.
+
+-------------------------------------------------------------------------
+
+Here is what needs to be done on a package by package basis for Java
+1.1 compatibility. Note that debugging should be done by running
+Mauve tests against Classpath where possible. If Mauve tests don't
+exist, the first step is to write them. Note that while I say "1.1",
+the implementations of these packages should be written to the "1.2"
+standard.
+
+-- java.applet: Coded and compiles cleanly. Needs debugging.
+
+-- java.awt: Mostly done and compiles cleanly. A few classes are
+ missing. Needs to be debugged and integrated with Paul Fisher's
+ AWT peers. This task should not be worked on for the time being.
+
+-- java.awt.datatransfer: Coded and compiles cleanly. Needs
+ debugging. This task should be considered "On Hold" for now.
+
+-- java.awt.event: Coded and compiles cleanly. Needs debugging.
+ This task should be considered "On Hold" for now.
+
+-- java.awt.image: Unsure of status but partially implemented.
+
+-- java.awt.peer: Done. Nothing needs to be done here.
+
+-- java.beans: Done. Additional testing/debugging/real life use
+ reports would be helpful, as would efficieny improvements.
+
+-- java.io: Needs to be merged with libgcj. See above.
+
+-- java.lang: Needs to be merged with libgcj. See above.
+
+-- java.math: Needs to be merged with libgcj. See above. Missing
+ some methods.
+
+-- java.net: Merger with libgcj in progress. No tasks to be done at
+ this time.
+
+-- java.rmi: No implementation. Rumor has it that Transvirtual (Kaffe)
+ is producing a version we can use.
+
+-- java.security: Debug the implementation and get it working with Japhar
+ and/or gcj. Mark Benvenuto (mcb54@columbia.edu) wrote this, but
+ I'm not sure that it is totally running.
+
+-- java.sql: Coded and compiles cleanly. Needs debugging.
+
+-- java.text: Needs to be merged with libgcj. See above.
+
+-- java.util: Needs to be merged with libgcj. See above
+
+-- java.util.zip: Need to merge in the libgcj version. See above.
+
+-------------------------------------------------------------------------
+
+-- Write Java 1.2 packages not currently included or improve existing
+ ones.
+
+-- Write an implementation of Swing. This is a big job and should
+ probably be a separate, non-Classpath project that can be shared
+ with Kaffe. Please write to the mailing list if you are interested
+ in helping with this. (classpath@gnu.org)
+
+-- Figure out an easy method of generating online Javadocs from our
+ code. This will probably involve lots of misc HTML fixes.
+
+-- Audit the code to identify methods that do not have Javadoc comments
+ and/or comments that are incomplete. All input parameters, return
+ values, etc should be documentes. Also look for Javadoc comments on
+ variables that are serializable.
+
+-- Figure out a way to generate a hardcopy manual for the Java class
+ library from the embedded Javadocs. This probably involves writing
+ a custom doclet and probably some supplementary documentation
+ files into which the extracted Javadoc files are included.
+
+-- Audit the code to ensure that all variable declarations are consistent
+ with the "Serialized Form" in the JDK. That is, all serialized
+ variables in the JDK should be included in Classpath and all Classpath
+ instance variables that are not part of the JDK docs should be marked
+ transient. Please be sure to use the online version of the Javadocs
+ for this and do not accept any "clickwrap" licenses from Sun in order
+ to download the JDK 1.2 Javadocs, which is where this information is
+ stored.
+
+-- Audit code similar to above to determine where Sun uses readObject()
+ and writeObject() for serialization and determine what Classpath
+ needs to do for compatibility.
+
+-- Audit code to ensure that every class that should be serializable
+ actually implementst java.io.Serializable and has the correct
+ serialVersionUID private static variable that is identical to the
+ JDK 1.1 version. You can obtain that variable value using the
+ serialver command.
+
+-- Do real life serialization compatibility tests of our code with Kaffe
+ and the JDK.
+
+-- Update the packaging of Classpath to make sure that we can build
+ good distribution tarballs.
+
+-- Bug reports are always welcome. They are double welcome if they
+ are accompanied by a Mauve test that reproduces the bug.
