* Remove a global mutex/state by using lists instead of hashtables to store thedkf2004-12-021-49/+51

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | startup/initialization of the Tcl library, focused on the activities of Tcl_FindExecutable(). * generic/tclIO.c: Removed bogus claim in comment that encoding "iso8859-1" is "built-in" to Tcl. * generic/tclInt.h: Created a new struct ProcessGlobalValue, * generic/tclUtil.c: routines Tcl(Get|Set)ProcessGlobalValue, and function type TclInitProcessGlobalValueProc. Together, these take care of the housekeeping for "values" (things that can be held in a Tcl_Obj) that are global across a whole process. That is, they are shared among multiple threads, and epoch and mutex protection must govern the validity of cached copies maintained in each thread. * generic/tclNotify.c: Modified TclInitNotifier() to tolerate being called multiple times in the same thread. * generic/tclEvent.c: Dropped the unused argv0 argument to TclInitSubsystems(). Removed machinery to unsure only one TclInitNotifier() call per thread, now that that is safe. Converted Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to tclEncoding.c. * generic/tclBasic.c: Updated caller. * generic/tclInt.h: TclpFindExecutable now returns void. * unix/tclUnixFile.c: * win/tclWinFile.c: * win/tclWinPipe.c: * generic/tclEncoding.c: Built new encoding search initialization on a foundation of ProcessGlobalValues, exposing new routines Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to directory pathname keeps track of where encodings are available for loading. Tcl_FindExecutable greatly simplified into just three function calls. The "library path" is now misnamed, as its only remaining purpose is as a foundation for the default encoding search path. * generic/tclInterp.c: Inlined the initScript that is evaluated by Tcl_Init(). Added verification after initScript evaluation that Tcl can find its installed *.enc files, and that it has initialized [encoding system] in agreement with what the environment expects. [tclInit] no longer driven by the value of $::tcl_libPath; it largely constructs its own search path now, rather than attempt to share one with the encoding system. * unix/tclUnixInit.c: TclpSetInitialEncodings factored so that a new * win/tclWinInit.c: routine TclpGetEncodingNameFromEnvironment can reveal that Tcl thinks the [encoding system] should be, even when an incomplete encoding search path, or a missing *.enc file won't allow that initialization to succeed. TclpInitLibraryPath reworked as an initializer of a ProcessGlobalValue. * unix/tclUnixTest.c: Update implementations of [testfindexecutable], [testgetdefenc], and [testsetdefenc]. * tests/unixInit.test: Corrected tests to operate properly even when a value of TCL_LIBRARY is required to find encodings. * generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath, TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These are candidates for public exposure by future TIPs. * generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c: * generic/tclTest.c: Updated [testencoding] to use * tests/encoding.test: Tcl(Get|Set)EncodingSearchPath. Updated tests.

| | | | | | | | * tests/unixInit.test: path used to locate init.tcl within [tclInit]. This change does not restore any directories to the encoding search path, so should still avoid the price of an unreasonably large number of filesystem accesses during encoding initialization at startup [Bug 976438]

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.
