Tcl Source Code

2008-09-02  Donal K. Fellows  <[email protected]>

	* tests/socket.test: Rewrote so as to use tcltest2 better.

2008-09-01  Miguel Sofer  <[email protected]>

	* generic/tclCmdAH.c:      nre-enabling [eval]; eval scripts are now
	* generic/tclOOBasic.c:    bytecompiled. Adapted recursion limit tests
	* tests/interp.test:       that were relying on eval not being 
	* tests/nre.test:          compiled. Part of the [Bug 2017632] project.
	* tests/unsupported.test:

2008-09-01  Donal K. Fellows  <[email protected]>

	* generic/tclOOMethod.c (InvokeProcedureMethod): 
	* generic/tclOO.c (ObjectRenamedTrace): Arrange for only methods that
	involve callbacks into the Tcl interpreter to be skipped when the
	interpreter is being torn down. Allows the semantics of destructors in
	a dying interpreter to be more useful when they're implemented in C.

2008-08-29  Donal K. Fellows  <[email protected]>

	* unix/Makefile.in: Ensure that all TclOO headers get installed.
	* win/Makefile.in:  [Bug 2082299]
	* win/makefile.bc: 
	* win/makefile.vc:
