* * generic/tclExecute.c (ExprAbsFunc): fixed the abs(MIN_INT) casermax2005-12-121-3/+3
| | | | | so that it doesn't break on compilers that don't assume integers to wrap around (e.g. gcc-4.1.0).
* * generic/tclExecute.c (ExprRoundFunc):mdejong2005-10-281-2/+2
| | | | | | | | | | | Fix typo where number before rounding is compared with smallest integer instead of number after rounding. This fix does not change the results of any tests. * tests/expr.test: Add round() tests for cases near the min and max int values. * tests/util.test: Remove pointless warning code about testobj command.

It is not possible to handle error returns correctly in that case [Bug 1334947], one has the choice of leaking the object in some cases, or else risk crashing in some others.

* * generic/tclExecute.c (INST_CONCAT1): added a peepholeMiguel Sofer2004-09-101-1/+15
| | | | | | optimisation for concatting an empty string. This enables replacing the idiom 'K $x [set x {}]' by '$x[set x {}]' for fastest execution.

* * generic/tclExecute.c (INST_INVOKE, INST_EVAL, INST_PUSH_RESULT):Miguel Sofer2003-08-051-4/+30
| | | | | | | | added a Tcl_ResetResult(interp) at each point where the interp's result is pushed onto the stack, to avoid keeping an extra reference that may cause costly Tcl_Obj duplication [Bug 781585] Detected by Franco Violi, analyzed by Peter Spjuth and Donal Fellows.
* * generic/tclBasic.c:Miguel Sofer2003-06-101-3/+6
| | | | | | | * generic/tclExecute.c: let TclExecuteObjvInternal call TclInterpReady instead of relying on its callers to do so; fix for the part of [Bug 495830] that is new in 8.4. * tests/interp.test: Added tests 18.9 (knownbug) and 18.10

| | | | | | | | | | | | | | | | | | | | | | * generic/tclObj.c is defined on all platforms, even those where * generic/tclPort.h TCL_WIDE_INT_IS_LONG is defined. Also made the Tcl_Value struct have a wideValue field on all platforms. This is a ***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms because that struct changes size. This is the same TIP 72 incompatibility that was seen on other platforms at the 8.4.0 release, when this change should have happened as well. [Bug 713562] * generic/tclInt.h: New internal macros TclGetWide() and TclGetLongFromWide() to deal with both forms of the "wideInt" Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code is confined to the header file. * generic/tclCmdAH.c: Replaced most coding that was conditional * generic/tclCmdIL.c: on TCL_WIDE_INT_IS_LONG with code that * generic/tclExecute.c: works across platforms, sometimes using * generic/tclTest.c: the new macros above to do it. * generic/tclUtil.c: * generic/tclVar.c:

Tcl_UniCharCaseMatch has the * tests/string.test: failing that it can't handle strings or * tests/stringComp.test: patterns with embedded NULLs. Added tests that actually try strings/pats with NULLs. TclUniCharMatch should be TIPed and made public in the next minor version rev.

| | | | | | | | | | | | | error is encountered reading the increment value during a compiled call to incr, add a "(reading increment)" error string to the errorInfo variable. This makes the errorInfo variable set by the compiled incr command match the value set by the non-compiled version. * tests/incr-old.test: Change errorInfo result for the compiled incr command case to match the modified implementation. * tests/incr.test: Add tests to make sure the compiled and non-compiled errorInfo messages are the same.
