Even with these revisions, the caller cannot be sure the library remains initialized. Any thread might call Tcl_Finalize() at any time. That's a deeper problem which this patch does not attempt to address. file: [2537f9a21e] check-in: [9cadc9f272] user: dgp branch: bug-3611974, size: 43352

TEBC now almost split in two: a command dispatcher and an expr evaluator. As their internal workings better hidden from the rest of Tcl, experiments to improve on each aspect are now easier. file: [4745dcd525] check-in: [ee6fe20b03] user: mig branch: mig-strip-brutal, size: 43104

add TCL_NOSIZE as internal defined for -1, and use it in a lot of places Ass this function argument should be size_t, not ssize_t (still to be TIPped), something like this will be needed anyway.

TIP #337 IMPLEMENTATION

* doc/BackgdErr.3: Converted internal routine * doc/interp.n: TclBackgroundException() into public routine * generic/tcl.decls: Tcl_BackgroundException(). * generic/tclEvent.c: * generic/tclInt.decls:

* generic/tclDecls.h: make genstubs * generic/tclIntDecls.h: * generic/tclStubInit.c:

* generic/tclIO.c: Update callers. * generic/tclIOCmd.c: * generic/tclInterp.c: * generic/tclTimer.c: *** POTENTIAL INCOMPATIBILITY only for extensions using the converted internal routine ***

* doc/Exit.3: do not call Tcl_Finalize implicitly * generic/tclEvent.c: on DLL_PROCESS_DETACH as it may lead * win/tclWin32Dll.c (DllMain): to issues and the user should be explicitly calling Tcl_Finalize before unloading regardless. Clarify the docs to note the explicit need in embedded use.

* generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd): Added error * tests/event.test (event-5.*): checking to protect against callers passing invalid return options dictionaries. [Bug 1901113]

* generic/tclBasic.c (Tcl_AppendObjToErrorInfo): Revised the refcount management of Tcl_AppendObjToErrorInfo to become that of a conventional Consumer routine. This preserves the ease of use for the overwhelming common callers who pass in a 0-count value, but makes the proper call with a non-0-count value less surprising. * generic/tclEvent.c (TclDefaultBgErrorHandlerObjCmd): Revised the one caller within Tcl itself which passes a non-0-count value to Tcl_AppendObjToErrorInfo().

* generic/tclEvent.c ([::tcl::Bgerror]): Corrections to Tcl's * tests/event.test: default [interp bgerror] handler so that when it falls back to a hidden [bgerror] in a safe interp, it gets the right error context data. [Bug 1790274].

* generic/tclResult.c (Tcl_GetReturnOptions): Take care that a * tests/init.test: non-TCL_ERROR code doesn't cause existing -errorinfo, -errorcode, and -errorline entries to be omitted. * generic/tclEvent.c: With -errorInfo no longer lost, generate more complete ::errorInfo when calling [bgerror] after a non-TCL_ERROR background exception.

* generic/tclInt.decls: New internal routine TclBackgroundException() * generic/tclEvent.c: that for the first time permits non-TCL_ERROR exceptions to trigger [interp bgerror] handling. Closes a gap in TIP 221. When falling back to [bgerror] (which is designed only to handle TCL_ERROR), convert exceptions into errors complaining about the exception.

* generic/tclInterp.c: Convert Tcl_BackgroundError() callers to call * generic/tclIO.c: TclBackgroundException(). * generic/tclIOCmd.c: * generic/tclTimer.c:

* generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c:

* generic/tclCompExpr.c: Removed dead code, old implementations * generic/tclEvent.c: of expr parsing and compiling, including the * generic/tclInt.h: routine TclFinalizeCompilation().

* generic/tclEvent.c (Tcl_CreateThread): Replaced some calls to * generic/tclPkg.c (CheckVersion): Tcl_Alloc() with calls to * unix/tclUnixTime.c (SetTZIfNecessary): ckalloc(), which better * win/tclAppInit.c (setargv): supports memory debugging.

* generic/tclBasic.c (Tcl_CreateMathFunc): Replaced some * generic/tclEvent.c (Tcl_CreateThread): calls to Tcl_Alloc() * generic/tclObj.c (UpdateStringOfBignum): with calls to * unix/tclUnixTime.c (SetTZIfNecessary): ckalloc(), which better * win/tclAppInit.c (setargv): supports memory debugging.

* generic/tclEvent.c (HandleBgErrors): Make efficient private copy * tests/event.test (event-5.3): of the command prefix for the interp's background error handling command to avoid panics due to pointers to memory invalid after shimmering. [Bug 1670155]

* generic/tclCompExpr.c: fix gcc warnings about 'cast to/from * generic/tclEncoding.c: pointer from/to integer of different * generic/tclEvent.c: size' on 64-bit platforms by casting to * generic/tclExecute.c: intermediate types intptr_t/uintptr_t * generic/tclHash.c: via new PTR2INT(), INT2PTR(), * generic/tclIO.c: PTR2UINT() and UINT2PTR() macros. * generic/tclInt.h: [Patch 1592791] * generic/tclProc.c: * generic/tclTest.c: * generic/tclThreadStorage.c: * generic/tclTimer.c: * generic/tclUtil.c: * unix/configure.in: * unix/tclUnixChan.c: * unix/tclUnixPipe.c: * unix/tclUnixPort.h: * unix/tclUnixTest.c: * unix/tclUnixThrd.c:

* unix/configure: autoconf-2.59 * unix/tclConfig.h.in: autoheader-2.59

* generic/tclEvent.c (HandleBgErrors): fix leak. [Coverity issue 86]

[kennykb-numerics-branch] Merge updates from HEAD

* generic/tclExecute.c: Bug fix. INST_*SHIFT* opcodes stack management. [expr 0<<6] should be 0, not 6.

*** MERGE WITH HEAD *** (tag msofer-wcodes-20050611)

* generic/tclEncoding.c: Different fix for [Bug 1077005]. * generic/tclEvent.c: Broke apart TclpSetInitialEncodings() on * generic/tclInt.h: Windows into TclpSetInterfaces(), that is * unix/tclUnixInit.c: fundamentally essential, and the initialization * win/tclWinInit.c: of the system encoding, which is not. Made the TclpSetInterfaces call part of TclInitSubsystems so it cannot be overlooked.

* generic/tclUtil.c: Updated Tcl_GetNameOfExecutable() to * generic/tclEncoding.c: make use of a ProcessGlobalValue for * generic/tclEvent.c: storing the executable name. Added internal routines Tcl(Get|Set)ObjNameOfExecutable() to access that storage in Tcl_Obj, rather than string format.

* unix/tclUnixFile.c: Rewrote TclpFindExecutable() to use * win/tclWinFile.c: TclSetObjNameOfExecutable to store the executable name it computes.

* generic/tclInt.h: Added internal stub entries for * generic/tclInt.decls: TclpFindExecutable and Tcl(Get|Set)ObjNameOfExecutable.

* generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c:

* generic/tclCmdIL.c: Retrieve executable name in Tcl_Obj form * win/tclWinPipe.c: instead of string form.

* unix/tclUnixTest.c: Update [testfindexecutable] command to use new internal interfaces.

Patch 976520 reworks several of the details involved with 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.

* generic/tclEvent.c (HandleBgErrors): Simplified program flow.

TIP #221 IMPLEMENTATION * generic/tclBasic.c: Define [::tcl::Bgerror] in new interps. * generic/tclEvent.c: Update Tcl_BackgroundError to make use of the registered [interp bgerror] command. * generic/tclInterp.c: New [interp bgerror] subcommand. * tests/interp.test: syntax tests updated.

TIP #226 IMPLEMENTATION * generic/tcl.decls: Stubs for Tcl_(Save|Restore|Discard)InterpState * generic/tcl.h: New public opaque type, Tcl_InterpState. * generic/tclInt.h: Drop old private declarations. Add Tcl(Get|Set)BgErrorHandler * generic/tclResult.c: Tcl_*InterpState implementations. * generic/tclDictObj.c: Update callers. * generic/tclIOGT.c: * generic/tclTrace.c:

TIP #227 IMPLEMENTATION * generic/tcl.decls: Stubs for Tcl_(Get|Set)ReturnOptions. * generic/tclInt.h: Drop old private declarations. * generic/tclResult.c: Tcl_*ReturnOptions implementations. * generic/tclCmdAH.c: Update callers. * generic/tclMain.c:

* generic/tclBasic.c (Tcl_LogCommandInfo,Tcl_AddObjErrorInfo): Shift the initialization of errorCode to NONE to more central location.

* generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors): Rewrite to build on the new TclGet/SetReturnOptions routines.

* generic/tclResult.c (TclGetReturnOptions): Add call to Tcl_AddObjErrorInfo to be sure error fields are initialized.

* generic/tclResult.c (TclTransferResult): Rewrite to build on the new TclGet/SetReturnOptions routines.

* generic/tclInt.h (Tcl*InterpState): New internal routines * generic/tclResult.c (Tcl*InterpState): TclSaveInterpState, TclRestoreInterpState, and TclDiscardInterpState are superior replacements for Tcl_(Save|Restore|Discard)Result. Intent is that these routines will be converted to public routines after TIP approval.

* generic/tclBasic.c (TclEvalObjvInternal): * generic/tclDictObj.c (DictUpdateCmd, DictWithCmd): * generic/tclIOGT.c (ExecuteCallback): * generic/tclTrace.c (Trace*Proc,TclCheck*Traces,TclCallVarTraces): Callers of Tcl_*Result updated to call the new routines. The calls were relocated in several cases to perform save/restore operations only when needed.

* generic/tclEvent.c (HandleBgErrors): * generic/tclFCmd.c (CopyRenameOneFile): Calls to Tcl_*Result that were eliminated because they appeared to serve no useful purpose, typically saving/restoring an error message, only to throw it away.

* 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.

That information is now primarily stored in a new private (Tcl_Obj *) field of the Interp struct, rather than using a global variable ::errorCode as the primary storage. The ERROR_CODE_SET 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 ::errorCode variable to hold the information.

* generic/tclBasic.c: Removed internal routines TclInvoke, * generic/tclInt.decls: TclGlobalInvoke, TclObjInvokeGlobal and * tests/basic.test: the portion of TclObjInvoke that handles calls without TCL_INVOKE_HIDDEN enabled. None of this code is called any longer within the core, and the superior public interface, Tcl_EvalObjv, is available for any external callers.

* generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c:

* generic/tclEvent.c (HandleBgErrors): Updated [bgerror] invocations to make use of Tcl_Obj based routines, dropping the calls to TclGlobalInvoke()

* generic/tclEvent.c (Tcl_Finalize): Re-organized Tcl_Finalize so that Tcl_ExitProc's that call Tcl_Finalize recursively do not cause deadlock. [Patch 999084 fixes Tk Bug 714956]

Patch 922727 committed. Implements three changes:

* generic/tclInt.h: Reworked the Tcl header files into a clean * unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h * win/tclWinInt.h: and every C source file should #include * win/tclWinPort.h: at most one of those files to satisfy its declaration needs. tclWinInt.h and tclWinPort.h also better organized so that tclWinPort.h includes the Windows implementation of cross-platform declarations, while tclWinInt.h makes declarations that are available on Windows only.

* generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h * generic/tclMath.h (removed): header file. The internal Tcl * macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a * win/tcl.dsp: #include <math.h> directly, and file external to Tcl needing libm should do the same.

* win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file. * win/makefile.bc (TCLOBJS): It's a vestige from matherr() days * win/makefile.vc (TCLOBJS): gone by. * win/tcl.dsp: * win/tclWinMtherr.c (removed):

Note that this branch currently does not fully support the new {expand} syntax. Updates to TclEvalScriptTokens and TclCompileScriptTokens are still to come. file: [8392f01b9c] check-in: [beeeb45bbf] user: dgp branch: dgp-refactor, size: 33060

* generic/tclEvent.c (Tcl_Finalize): revert finalize change on 2002-12-04 to correct the issue with extensions that have TSD needing to finalize that before they are unloaded. This issue needs further clarification.

* generic/tclEvent.c (TclInExit, TclInThreadExit): Split out functionality of TclInExit to make it clear which one should be called in each situation. * generic/tclInt.decls: Declare TclInThreadExit. * generic/tclIntDecls.h: Regen. * generic/tclStubInit.c: Regen. * mac/tclMacChan.c (StdIOClose): * unix/tclUnixChan.c (FileCloseProc): * win/tclWinChan.c (FileCloseProc): * win/tclWinConsole.c (ConsoleCloseProc): * win/tclWinPipe.c (TclpCloseFile): * win/tclWinSerial.c (SerialCloseProc): Invoke the new TclInThreadExit method instead of TclInExit.

* doc/CmdCmplt.3: Applied Patch 585105 to fully CONST-ify * doc/Concat.3: all remaining public interfaces of Tcl. * doc/CrtCommand.3: Notably, the parser no longer writes on * doc/CrtSlave.3: the string it is parsing, so it is no * doc/CrtTrace.3: longer necessary for Tcl_Eval() to be * doc/Eval.3: given a writable string. Also, the * doc/ExprLong.3: refactoring of the Tcl_*Var* routines * doc/LinkVar.3: by Miguel Sofer is included, so that the * doc/ParseCmd.3: "part1" argument for them no longer needs * doc/SetVar.3: to be writable either. * doc/TraceVar.3: * doc/UpVar.3: Compatibility support has been enhanced so * generic/tcl.decls that a #define of USE_NON_CONST will remove * generic/tcl.h all possible source incompatibilities with * generic/tclBasic.c the 8.3 version of the header file(s). * generic/tclCmdMZ.c The new #define of USE_COMPAT_CONST now does * generic/tclCompCmds.c what USE_NON_CONST used to do -- disable * generic/tclCompExpr.c only those new CONST's that introduce * generic/tclCompile.c irreconcilable incompatibilities. * generic/tclCompile.h * generic/tclDecls.h Several bugs are also fixed by this patch. * generic/tclEnv.c [Bugs 584051,580433] [Patches 585105,582429] * generic/tclEvent.c * generic/tclInt.decls * generic/tclInt.h * generic/tclIntDecls.h * generic/tclInterp.c * generic/tclLink.c * generic/tclObj.c * generic/tclParse.c * generic/tclParseExpr.c * generic/tclProc.c * generic/tclTest.c * generic/tclUtf.c * generic/tclUtil.c * generic/tclVar.c * mac/tclMacTest.c * tests/expr-old.test * tests/parseExpr.test * unix/tclUnixTest.c * unix/tclXtTest.c * win/tclWinTest.c

* Updated interfaces of generic/tclVar.c according to TIP 27. In particular, the "part2" arguments were CONSTified.

* Updated interfaces of generic/tclEncoding, generic/tclFilename.c, generic/tclIOUtil.c, generic/tclPipe.c, generic/tclResult.c, generic/tclUtil.c, generic/tclVar.c and mac/tclMacResource.c according to TIP 27. Tcl_TranslateFileName rewritten as wrapper around VFS-aware version. Updated callers. ***POTENTIAL INCOMPATIBILITY*** Includes source incompatibilities: argv arguments of Tcl_Concat, Tcl_JoinPath, Tcl_OpenCommandChannel, Tcl_Merge; argvPtr arguments of Tcl_SplitList and Tcl_SplitPath.

* More TIP 27 updates in tclIOUtil.c and tclIndexObj.c that were overlooked before. Updated callers. ***POTENTIAL INCOMPATIBILITY*** Includes a source incompatibility in the tablePtr arguments of the Tcl_GetIndexFromObj* routines.

* generic/tclEvent.c (TclInExit): * generic/tclIOUtil.c (SetFsPathFromAbsoluteNormalized, SetFsPathFromAny,Tcl_FSNewNativePath,DupFsPathInternalRep): * generic/tclListObj.c (TclLsetList,TclLsetFlat): Added some type casts to satisfy picky compilers.

* tclCmdMZ.c: * tclCompCmds.c: * tclCompile.c: * tclEvent.c: * tclExecute.c: * tclNamesp.c: * tclParse.c: * tclProc.c: * tclUtil.c: More places using TCL_STRUCT_ON_HEAP.

* static.sizes.html: New file. Report on the cuts achieved so far. Regarding the object files only the files which did change in size are reported. Usage of the MODULAR_TCL macro currently cuts about 17 % of the code (measured using strip'ped object files and libraries).

* Changed files so far .. [cut, see changelog for full list]

* Working on modularization of the tcl core.

* generic/tclAsync.c: * generic/tclEvent.c: * generic/tclInt.h: Improper cleanup of asyncMutex in tclAsync.c repaired. TclFinalizeSynchronization() was trying to remove a registered mutex that was dumped earlier when the TSD it was stored in was cleared. This was only surfacing on *nix. Windows was being masked by mutexes not actually being returned to the system! That was repaired in a previous patch.

* generic/tclCkalloc.c (TclFinalizeMemorySubsystem): set curTagPtr to NULL to allow for reuse. * generic/tclEvent.c (Tcl_Finalize): moved the tsdPtr initialization inside the subsystemsInitialized check to prevent it potentially getting called twice during finalization. (wu) [Patch #403532, Bug #219391]

* generic/tclEvent.c: tclLibraryPath Tcl_Obj didn't have a way to share its data among threads. This caused Tcl_Init() to always fail in threads. Added a way to pass the data around with a global char*. [BUG: 5301]

* generic/tclEvent.c (TclInitSubsystems): Moved tclLibraryPath to thread-local storage to prevent thread-related race condition. [Bug: 5033]

Fixed the thread send command to unlink the result from the global result list while still inside the mutex. file: [f7a23f9e5e] check-in: [c3634cbd75] user: welch branch: core-8-1-branch-old, size: 30726

What I Changed -------------- 1) Modified generic/tclInt.h a) Added cache of the tclNativeExecutable name so the variable does not have be recomputed on subsequent calls to TclpFindExecutable. a) Added variable tclDefaultEncoding dir to store the path to the encoding files. b) Added prototype for TclpFindExecutable & TclpFindEncodings.

2) Modified generic/tclInitScript.h a) Added the TclSetPreInitScript proc and pointer to the script.

3) Modified generic/tclUtil.c a) Added initialization of the tclNativeExecutableName.

4) Modified generic/tclEvent.c a) Added boolean that indicates if the encodings have been initialized. b) Modified TclInitSubsystems so it only initializes "in-memory" subsystems, and not the encoding sub system. c) Added TclFindEncodigs procedure to initialize the encoding subsystem. d) Tcl_Finallize cleans up memory allocated for tclNativeExecutableName and tclDefaultEncodingDir.

5) Modified generic/tclEncoding.c a) Added intialization of the tclDefaultEncodingDir variable. b) Added two accessor functions, Tcl_GetDefaultEncodingDir and Tcl_SetDefaultEncodingDir. c) Made Tcl_FindExecutable platform independent, and moved to this file.

6) Modified unix/tclUnixFile.c and win/tclWinFile.c a) Added TclpFindExecutable(argv0) to compute a native string. c) Tcl_FindExecutable calls TclpFindExecutable to get the native string. d) Modified the TclpInitLibraryPath lookup algorithm (see below)

7) Modified unix/tclUnixInit.c and win/tclWinInit.c a) Added the call evaluate to the pre-init script b) Modified TclpInitLibraryPath to take a native path to the executable so it does not have to call Tcl_FindExecutable. c) On windows, the AppendRegistry routine was removed.

8) Modified unix/tclUnixTest.c a) Modified TestfindexecutableCmd to reset the cached value of tclNativeExecutable name. file: [e35487b3f1] check-in: [f989579c4c] user: surles branch: core-8-1-branch-old, size: 29664

* generic/tclEncoding.c (Tcl_FreeEncoding): Moved most of the code into a static FreeEncoding routine that does not grab the encodingMutex to avoid deadlocks/races when called from other routines that already have the mutex. file: [e50988923c] check-in: [09f356baa2] user: stanton branch: core-8-1-branch-old, size: 28294
