Fellows <fellowsd@cs.man.ac.uk> + + * generic/tclCmdIL.c (Tcl_LrepeatObjCmd): Check for sensible list + lengths and allow for soft failure of the memory subsystem in the + [lconcat] command [Bug 829027]. Uses direct list creation to + avoid extra copies when working near the limit of available + memory. Also reorganized to encourage optimizing compilers to + optimize heavily. + * generic/tclListObj.c (TclNewListObjDirect): New list constructor + that does not copy the array of objects. Useful for creating + potentially very large lists or where you are about to throw away + the array argument which is being used in its entirety. + 2003-10-28 Miguel Sofer <msofer@users.sf.net> * generic/tclExecute.c (NEXT_INST macros): replaced macro variable |
