* * generic/tclExecute.c (TclExecuteByteCode):mdejong2005-07-091-49/+141
| | | | | | | | | | | | | | | | | Reimplement long and wide type integer division and modulus operations so that the smallest and largest integer values are handled properly. The divide operation is more efficient since it no longer does a modulus or negation and only checks for a remainder when the quotient will be a negative number. The modulus operation is now a bit more complex because of a number of special cases dealing with the smallest and largest integers. * tests/expr.test: Add test cases for division and modulus operations on the smallest and largest integer values for 32 and 64 bit types. [Patch 1230205]
* * generic/tclExecute.c (TclExecuteByteCode):mdejong2005-06-291-5/+29
| | | | | | | | | | | When parsing an integer operand for a unary minus expression operator, check for a wide integer that is actually LONG_MIN. If found, convert it back to a long int type. * tests/expr.test: Add constraint for 32bit long int type and 64bit wide int type. Add tests that parse the smallest/largest long int and wide int values.

| | | | | | | | | | | | | | | | Tcl_ExprBooleanObj. * generic/tclCmdMZ.c ([string is boolean/true/false]): Rewrite dropping string-based Tcl_GetBoolean call, so that internal reps are kept for subsequent quick boolean operations. * generic/tclExecute.c: Dropped most special handling of the "boolean" Tcl_ObjType, since that type should now be rarely encountered. * doc/BoolObj.3: Rewrite of documentation dropping many details about the internals of Tcl_Objs. Shorter documentation focuses on the function and use of the routines.

| | | | | | | | | | | | | | | | | | | | | | | | | it into agreement with its docs. Further investigation reveals it was the docs that were incorrect. * doc/BoolObj.3: Corrections to the documentation of Tcl_GetBooleanFromObj to bring it into agreement with what this public interface has always done, including noting the difference in function between Tcl_GetBooleanFromObj and Tcl_GetBoolean. * generic/tclGet.c: Revised Tcl_GetBoolean to no longer be a wrapper around Tcl_GetBooleanFromObj (different function!). * generic/tclObj.c: Removed TclGetTruthValueFromObj routine that was added yesterday. Revisions so that only Tcl_GetBoolean-approved values get the "boolean" Tcl_ObjType. This retains the fix for [Bug 1187123]. * generic/tclInt.h: Revert most recent change. * generic/tclBasic.c: * generic/tclCompCmds.c: * generic/tclDictObj.c: * generic/tclExecute.c: * tests/obj.test:

| | | | | | | | | | | | | | | | | | Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj(). Reduces code duplication, and the resulting potential for inconsistency. * generic/tclObj.c: Several changes: - Fixed Tcl_GetBooleanFromObj to agree with its documentation and with Tcl_GetBoolean, accepting only "0" and "1" and not other numeric strings. [Bug 1187123] - Added new private routine TclGetTruthValueFromObj to perform the more permissive conversion of numeric values to boolean that is needed by the [expr] machinery. * generic/tclInt.h (TclGetTruthValueFromObj): New routine. * generic/tclExecute.c: Updated callers to call new routine. * tests/obj.test: Corrected bad tests that actually expected values like "47" and "0xac" to be accepted as booleans.

* Changed the internal representation of lists to (a) reduce the malloc/freeMiguel Sofer2005-04-021-5/+4
| | | | | | | | calls at list creation (from 2 to 1), (b) reduce the cost of handling empty lists (we now never create a list internal rep for them), (c) allow refcounting of the list internal rep. The latter permits insuring that the pointers returned by Tcl_ListObjGetElements remain valid even if the object shimmers away from its original list type. This is [Patch 1158008]

* * generic/tclTest.c: Added two new functions to allocate memoryMiguel Sofer2004-12-151-1/+82
| | | | | | | | | | from the execution stack (TclStackAlloc, TclStackFree). Added functions TclPushStackFrame and TclPopStackFrame that do the work of Tcl_PushCallFrame and Tcl_PopCallFrame, but using frames allocated in the execution stack - i.e., heap instead of C-stack. The core uses these two new functions exclusively; the old ones remain for backwards compat, as at least two popular extensions (itcl, xotcl) are known to use them.

| | | | | | | | | | | | | Removed several DECACHE_INFO/CACHE_INFO pairs that are no longer needed for protection because routines like Tcl_SetErrorCode() and Tcl_AddErrorInfo() can no longer re-enter bytecode execution. * generic/tclResult.c (TclProcessReturn): Bug fix. Be sure that a missing -errorinfo option when code == TCL_ERROR causes the errorInfo field to get reset. * tests/thread.test (thread-4.4): Test depended on a ::errorInfo value initialized to "". Added code to test to setup that requirement.

That information is now primarily stored in a new private (Tcl_Obj *) field of the Interp struct, rather than using a global variable ::errorInfo as the primary storage. The ERR_IN_PROGRESS flag bit value is no longer required to manage the value in its new location, and is removed. Variable traces are established to support compatibility for any code expecting the ::errorInfo variable to hold the information. ***POTENTIAL INCOMPATIBILITY*** Code that sets traces on the ::errorInfo variable may notice a difference in timing of the firing of those traces. Code that uses the value ERR_IN_PROGRESS.

Searched for example of this practice and replaced with safer alternatives, often using the Tcl_AppendResult() routine that dkf just rehabilitated.
