New subversion repository now available for top

I have created a mirror of my internal development svn repository for top that is available for public read-only access. This repository stays up-to-date. Thus it is possible that code contained in the repository will not compile or will contain bugs. It is a working copy. The main trunk can be accessed here:

Top subversion repository removed from Sourceforge

Regrettably I have had to disable top's subversion repository on SourceForge. The way I was trying to use the repository was not consistent with the way that SourceForge is set up. I am hoping to find another place where I can host the repository in a read-only manner.

Top 3.6 is released

Many changes from 3.5. Uses gnu configure script, supports ANSI color, updates to memory statistics provide more consistency in the information, updates to most modules, many bug fixes. Unfortunately I have had to temporarily remove support for MacOSX as it is too difficult for me to support at this time.

Top 3.6beta5 is released

If nothing else comes up within the next two weeks this will become release 3.6. Changes this release: Minor changes to eliminate warnings from the Sun Studio compiler. These were mostly sloppy argument declarations. I also added message.h to provide an interface file for just the message related functions of display.c.

Top 3.6 beta3 is released

Changes in this beta:

Set up a color tagging mechanism in color.c to allow for the dynamic creation of tag names to contol color highlighting. These names are partially derived from the tags used to label memory and swap information on the screen, thus are driven by the machine module itself. Added -T option to list color highlighting information. Help screen now includes the actual list of sort order names. Incorporated some minor fixes to the main code from the Freebsd source tree. Fixed bug #1324582. Freebsd 5: removed WCPU column and added THR column. Display for freebsd 4 and earlier unchanged since they don't track threads in the kernel. Added LICENSE file to distribution.
