Tcl Source Code

2011-04-04  Donal K. Fellows  <[email protected]>

	* library/init.tcl (tcl::mathfunc::rmmadwiw): Disable by default to
	make test suite work.

	* generic/tclBasic.c, generic/tclStringObj.c, generic/tclTimer.c,
	* generic/tclTrace.c, generic/tclUtil.c: More generation of error
	codes ([format], [after], [trace], RE optimizer).

2011-04-04  Jan Nijtmans  <[email protected]>

	* generic/tclCmdAH.c:  Better error-message in case of errors
	* generic/tclCmdIL.c:  related to setting a variable. This fixes
	* generic/tclDictObj.c: a warning: "Why make your own error
	* generic/tclScan.c:   message? Why?"
	* generic/tclTest.c:
	* test/error.test:
	* test/info.test:
	* test/scan.test:
	* unix/tclUnixThrd.h:  Remove this unused header file.

2011-04-03  Donal K. Fellows  <[email protected]>

	* generic/tclNamesp.c, generic/tclObj.c, generic/tclPathObj.c:
	* generic/tclPipe.c, generic/tclPkg.c, generic/tclProc.c:
	* generic/tclScan.c: More generation of error codes (namespace
	creation, path normalization, pipeline creation, package handling,
	procedures, [scan] formats)

2011-04-02  Kevin B. Kenny  <[email protected]>

	* generic/tclStrToD.c (QuickConversion): Replaced another couple
	of 'double' declarations with 'volatile double' to work around
	misrounding issues in mingw-gcc 3.4.5.

2011-04-02  Donal K. Fellows  <[email protected]>

	* generic/tclInterp.c, generic/tclListObj.c, generic/tclLoad.c:
	More generation of errorCodes ([interp], [lset], [load], [unload]).

	* generic/tclEvent.c, generic/tclFileName.c: More generation of
	errorCode information (default [bgerror] and [glob]).

2011-04-01  Reinhard Max  <[email protected]>

	* library/init.tcl: TIP#131 implementation.

2011-03-31  Donal K. Fellows  <[email protected]>

	* generic/tclGetDate.y, generic/tclDate.c (TclClockOldscanObjCmd):
	More generation of errorCode information.
