Differences From Artifact [b41f98b53d]:

• File generic/tclIOUtil.c — part of check-in [264b4df978] at 2004-10-15 04:01:22 on branch trunk — * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp, TclEvalObjvInternal,Tcl_LogCommandInfo,TclAddObjErrorInfo): * generic/tclCmdAH.c (Tcl_CatchObjCmd): * generic/tclEvent.c (BgError,ErrAssocData,Tcl_BackgroundError, HandleBgErrors,BgErrorDeleteProc): * generic/tclExecute.c (TclCreateExecEnv,TclDeleteExecEnv): * generic/tclIOUtil.c (comments only): * generic/tclInt.h (ExecEnv,Interp, ERR_IN_PROGRESS): * generic/tclInterp.c ([tclInit]): * generic/tclMain.c (comments only): * generic/tclNamesp.c (Tcl_CreateNamespace,Tcl_DeleteNamespace,TclTeardownNamespace): * generic/tclProc.c (TclUpdateReturnInfo): * generic/tclResult.c (Tcl_ResetResult,TclTransferResult): * generic/tclTrace.c (CallVarTraces): Reworked management of the "errorInfo" data of an interp. 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. (user: dgp size: 138825)

To Artifact [bf550cdf71]:

• File generic/tclIOUtil.c — part of check-in [5ce5994b49] at 2004-11-17 00:31:34 on branch trunk — * generic/tclIOUtil.c (TclFSEpochOk): There were two code paths via which the thread copy of filesystemEpoch could be synched with the master copy, but only one kept the filesystem list cache up to date. Fix routes everything through a single code path. [Bug 1035775]. (user: dgp size: 138651)
