A new sub-project of EMFT is created and the initial code base committed,
named Transaction (a.k.a. EMF-TX). It consists of two layered APIs: a
base layer providing a transactional editing domain (TXEditingDomain) and a
workbench integration layer that bridges the TXEditingDomain with the
operation history API in Eclipse runtime and, to a lesser extent, the
workspace API.
For more details, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=113708.
Note that builds are not yet available, but should be coming soon. For now,
the code can be checked out from CVS in the org.eclipse.emft/transaction
module of the technology repository.

When you say "operation history API in Eclipse runtime", do you mean this is
migrating to the shared Eclipse command stack APIs, and moving away from the
EMF command stack and GMF CommandManager? I've been trying to sort out the
GMF command history stacks for undo/redo support this past week, and found
it very confusing with the variety of command APIs used by these different
components.
Thanks,
Dave Carlson

Hi, Dave,
Work is beginning on refactoring the GMF runtime onto this new EMF
transaction API, to replace of the MEditingDomain and related APIs.
Concomitant to this is the replacement of the GMF CommandManager with the
OperationHistory. Thus, GMF will end up using only one "stack" for
"commands" (though I'm not sure about GEF plans for adopting the operation
history).
The EMFT Transaction project's basic editing domain implementation continues
to use an EMF CommandStack to support applications that deploy in
non-Eclipse environments (where there is no OperationHistory). We also
provide an editing domain whose command stack delegates to the operation
history. Or, you can use the OperationHistory directly as your command
stack, bypassing the editing domain's stack. Basically, we can't provide
an editing domain without a command stack but we can provide one that works
without it.
Cheers,
Christian

Hi Christian,
Thanks much for your explanation. I've not yet studied the eclipse
operation history implementation (used only the EMF commands this past
year). But I will review the EMFT transactions and eclipse history.
Do you expect this refactoring and adoption of EMF-TX and OperationHistory
to be complete by GMF 1.0 in June?
Thanks,
Dave

Bug 112826 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=112826) is
tracking the GMF adoption of the operation history API, and is currently
forecast for M5.
