@section Projects Looking for Volunteers

If you think you can do one of these projects, please let me know.  Your
help is greatly appreciated.  Send email to
@samp{mccallum@@gnu.ai.mit.edu}. 

@itemize @bullet

@item Write a test-suite for the library.  Use dejagnu.

@item Write a proper name server for Port's.  Currently we're just
hashing the name to a socket port number---we could get unwanted hash
collisions.  This will also allow us to name a SocketPort after it's
been created.

@ignore
@item Add some features to the compiler:  
@enumerate
@item You can't add __attribute__'s to methods.  I want to use: 
@smallexample
   - (int) writeFormat: (const char *)format, ... 
       __attribute__ ((format (printf, 1, 2)));
   - (int) readFormat: (const char *)format, ...
       __attribute__ ((format (scanf, 1, 2)));
@end smallexample
@item I would like to be able to use a function name/pointer as an
argument to @@encode() and get a type string like the selector types.
@end enumerate
@end ignore

@item Write some code to deal with `%@@' in printf-style format strings
for systems that do not have the GNU C library.  Those with the GNU C
Library can just use @samp{register_printf_function}.

@item Implement efficient SmallInt and SmallFloat classes in the same
sort of way that Smalltalk does.  Talk to me.  mccallum@@gnu.ai.mit.edu.

@item See
http://www.cs.rochester.edu/u/mccallum/libgnustep-base/volunteers.html for
a list of the claimed and unclaimed GNUStep Foundation classes.

@section McCallum's To Do's

@itemize @bullet

@item Make sure the GNU Archiver/Unarchiver handle
-encodeConditionalObject: and -decodeObject: correctly.

@item Reorganize some of the Categories to make a minimal NSObject-using
program smaller.  Currently it is huge becuase it pulls in archiving and
therefore many of the collection classes.

@item Make sure that Encoder's properly release their CStream and
Stream's.  It seems that the Stream is not getting -delloc'ed, and
therefore may not be closed, and therefore may be missing data at the
end. 

@item Change all the assert()'s (especially in the archiving code) to
NSAssert()'s.  This will help make D.O. servers more safe from bad
clients. 

@item Make my NS... classes raise the NSExceptions they are supposed to.
Change many NSParameterAssert()'s into NSAssert()'s with explanations.

@item Do low-level frobbing of TCP to reduce delays.

@item Make UdpPort work; make MachPort work.

@item Write NSRunLoop class, on top of GNU RunLoop.

@item Finish NotificationQueue, and make it interoperate with the
RunLoop properly.

@item Make the NSTimer's work and interoperate with the run loop
properly. 

@item Clean up and finish the String object situation.

@item Fix many memory allocation inconsistencies.  Methods that return
malloced buffers should autorelease those buffers, (like readFormat:).

@item Many code fixes and cleanups, indicated with @samp{xxx} in the
source.

@item Add Coding methods to all the collection classes.

@item Finish Collection heirarchy clean ups.  We need non-mutable
version for many of the classes.

@item
Possibly change @code{-(int)compare:anObject} for Collection.  How
should non-Indexed collections be ordered?

@item
Finish HashTable.m.  Implement freeKeys:values: (What is this supposed
to do anyway?).  Handle archiving of atom string, "%", keys.

@item
Finish Time.m.  Many methods are not yet implemented.

@item
Many implementations could be made more efficient.  Libobjects hasn't
been efficiency tuned very much.  Overridding more methods in certain
classes could make things more efficient (especially EltNodeCollector).
SplayTree's could be done using top-down splaying.  collhash could be
completely reimplemented.  ...and a lot more...

@item
Fix all the subclassResponsibility comments in objects/*.h

@item
I will finish gnustep-base documentation.

@c ==================================================================
@section Questions

I would greatly appreciate your feedback on the questions
below.  Please email your thoughts to mccallum@@gnu.ai.mit.edu.

@itemize @bullet

@item
I want to put method names in texinfo indices, but the colons in the
method names are interfering with info's notion of menu item names and
node names.  Help.  Any ideas?  (Kresten?)

@item
HashTable.m (-initKeyDesc:valueDesc:capacity:)  I tried to make it
portable, but I didn't try very hard.  Anyone want to send in fixes?

@item
I fixed -emptyCopy in all the subclasses, but the -emptyCopy scheme
seems pretty fragile.  How about calling -initFoo: inside -emptyCopy?
This way we avoid having yet another method in which instance vars
must be initialized to some consistent state.  -allocCopy would never
even get called.  <<ObjC insiders: This is a less well-expressed
version of what we've just been discussing in email.>>

@item
I created libgnustep-base.texi by copying libg++.texi.  Some of the text
is taken verbatim.  Is this a problem?

@item
If you don't like the organization of the documentation and you have
suggestions for changes, please say so now, not after it's all been
written. 

@item
Does anyone really need the ability to set the collection element
comparison function independent of the -compare: method?

@item
How about adding flexibity in the method name that a LinkedList sends a
LinkedListNode to get/set the link ivars.  This would enable us to add a
node to more than one linked list.

@item
Something like this needed?
- elementDidChange: (elt*)elementPtr;
Currently you have to remove, change, add, for some classes.

@c -------------------------------------------------------------------
@c @section Questions leftover from last release 

@item
I've been told that GNU filenames should be 14 chars or less.  I
don't want to abbreviate my classnames, but I think using .h
@@interface files with names different than the class name is even
worse.  ** I want to keep my unabbreviated filenames!! **  What to do,
what to do... I can't believe that *all* GNU classnames will be
limited to 12 characters forever and ever---disgusting.
