I have created a SqueakSource project called SystemTracing to serve
as a repository for the various SystemTracer implementations that have
appeared in and around Squeak images since Squeak 1.22. The intent is
to make these implementations loadable in modern images, and to provide
a Monticello repository for new development.
All classes and package extension methods have been recategoried to
SystemTracing but are otherwise unmodified to the extent possible.
The recategorizing was done by hand-editing the original change sets.
The archive includes historical versions that appeared in early Squeak
images, as well as loadable versions of the SystemTracer2 that is
catalogued on SqueakMap. There is an entry for the SystemTracer64
that was used to produce the first 64-bit Squeak image, and recent
updates that will enable 64-bit images to be traced from modern
Squeak and Pharo images (there is more work to be done here).
Developer access is provided for Stephen Pair, John M McIntosh,
Andreas Raab, Eliot Miranda, Jannik Laval, Ian Piumarta. If anyone
else should be added as developer, please speak up. All future
contributions to this archive are required to be MIT licensed.
