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. + 2004-11-30 Kevin B. Kenny <kennykb@acm.org> * library/clock.tcl: Corrected the regular expressions that match |
