2004-10-22 Donal K. Fellows * generic/tclNamesp.c (NsEnsembleImplementationCmd): Make ensembles cut their implementations out of error traces. This is the right thing to do more often than not. 2004-10-22 Kevin B. Kenny * library/clock.tcl: Fixed a typo where the fallback time zone became ::localtime instead of :localtime. Fixed a bug where time zone names containing hyphens could not be loaded. * tests/clock.test: Added regression test cases that covers both bugs. Thanks to Todd M. Helfter for finding these bugs. 2004-10-22 Donal K. Fellows * generic/tclExecute.c (TclCompEvalObj, Tcl_ExprObj): * generic/tclProc.c (TclProcCompileProc): Always call object freeIntRepProc's in the same way. 2004-10-22 Miguel Sofer * generic/tclVar.c: fixed bug in commit of 2004-07-23, which was causing a leak of Proc structures and failure of compile-12.1. Two lines were 'zombies' from the previous way localVarNames worked. Credit dgp for finding this. 2004-10-21 Don Porter * generic/tclInt.h (Interp): * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp): * generic/tclResult.c (GetKeys,ReleaseKeys,etc.): Moved the key values of the return options dictionary out of private fields of the Interp struct and into thread-static values managed in tclResult.c. * generic/tclCmdAH.c (Tcl_CatchObjCmd, Tcl_ErrorObjCmd): Updated to call the new TclGet/SetReturnOptions routines to do much of their work. * generic/tclInt.h (TclGetReturnOptions,TclSetReturnOptions): * generic/tclResult.c (TclGetReturnOptions,TclSetReturnOptions): New utility routines to get/set the return options of an interp. Intent is that these routines will be converted to public routines after TIP approval. * generic/tclCmdMZ.c (TclProcessReturn,TclMergeReturnOptions): * generic/tclResult.c (TclProcessReturn,TclMergeReturnOptions): Move internal utility routines from tclCmdMZ.c to tclResult.c. * generic/tclBasic.c (Tcl_CreateInterp, Tcl_DeleteInterp): * generic/tclResult.c (TclTransferResult): Rework so that iPtr->returnOpts can be NULL when there are no special options. * generic/tclResult.c (TclRestoreInterpState): Plug potential memory leak. 2004-10-21 Kevin B. Kenny * generic/tclBasic.c: Various changes to [clock format] that, * generic/tclClock.c: together, make it roughly twice as fast * generic/tclInt.h: while all tests in the test suite * library/clock.tcl: continue to pass. 2004-10-20 Andreas Kupries * win/Makefile.in (install-msgs): Fixed a problem with the * win/Makefile.in (install-tzdata): installation of timezone data and message catalogs. They used the installed tcl library directory, not the source library. Before it was installed. Switched to source lib dir. Thanks to Kevin for the help in figuring this out. 2004-10-20 Don Porter * generic/tclThreadTest.c (ThreadEventProc): Corrected subtle bug where the returned (char *) from Tcl_GetStringResult(interp) continued to be used without copying or refcounting, while activity on the interp continued. That's not safe, and recent changes demonstrated the lack of safety with failing tests thread-4.3 and thread-4.5. 2004-10-19 Donal K. Fellows * generic/tclDictObj.c (DictWithCmd): Make sure all paths (that are not themselves error paths) do not lose the result code. 2004-10-19 Don Porter * 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. Interfaces for these routines were shamelessly stolen from Itcl. * 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. 2004-10-18 Don Porter * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp): * generic/tclCmdAH.c (Tcl_CatchObjCmd): * generic/tclCmdMZ.c (TclMergeReturnOptions,TclProcessReturn): * generic/tclCompCmds.c (TclCompileReturnCmd): * generic/tclExecute.c (TclCompEvalObj): * generic/tclInt.h (Interp): * generic/tclProc.c (TclUpdateReturnInfo): Place primary storage of the -level and -code information in private fields of the Interp struct, rather than in a DictObj. This should significantly improve performance of TclUpdateReturnInfo. 2004-10-17 Miguel Sofer * generic/tclResult.c: removed unused variable [Bug 1048588]. Thanks to Daniel South. 2004-10-15 Don Porter * generic/tclCmdMZ.c (TclProcessReturn): Now that primary * generic/tclProc.c (TclUpdateReturnInfo): storage for the errorInfo and errorCode values are internal fields, we can set them at the time of the [return] command, and not have to wait until the specified number of "-level"s have popped. * 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. 2004-10-14 Donal K. Fellows TIP#217 IMPLEMENTATION * generic/tclCmdIL.c (Tcl_LsortObjCmd): Add -indices option from James Salsman.

Fellows * *.3: Convert CONST to const and VOID to void so we document how people should actually use the Tcl API and not the compatability hacks that it has to have. * doc/man.macros, *.3: Update .AS macro so it can know how wide to make the third column of the argument list. Update documentation for C API (only users) to take advantage of this. * doc/FileSystem.3: Formatting fixes for greater documentation clarity. 2004-10-06 Donal K. Fellows * generic/tclFileName.c (DoGlob, TclGlob): Stop messy sharing of interpreter result and instead use a private object for collecting the result of the glob. This simplifies TclGlob quite a lot. * generic/tclIOUtil.c (Tcl_FSMatchInDirectory): Simplify by removing some nesting. Also standardize variable names. (FsAddMountsToGlobResult): Force updates to the list to be done in-place, putting a side-condition of non-shared-ness on the resultPtr argument to Tcl_FSMatchInDirectory, but everything would have broken before if that was shared *anyway*. * generic/tclEncoding.c (LoadTableEncoding): Removed reference to Tcl interpreter; it wasn't needed as direct object use is more efficient. * generic/tclPathObj.c: Made this file follow the style rules in the Engineering Manual more closely, and also take advantage of the internal object manipulation macros more. * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Reorganized to have fewer magic flag variables and to separate the code that scans for a match from the code that processes a match body. 2004-10-06 Don Porter * generic/tclBasic.c: * generic/tclBinary.c: * generic/tclCmdAH.c: * generic/tclCmdIL.c: * generic/tclCmdMZ.c: * generic/tclCompExpr.c: * generic/tclDictObj.c: * generic/tclEncoding.c: * generic/tclExecute.c: * generic/tclFCmd.c: * generic/tclHistory.c: * generic/tclIndexObj.c: * generic/tclInterp.c: * generic/tclIO.c: * generic/tclIOCmd.c: * generic/tclNamesp.c: * generic/tclObj.c: * generic/tclPkg.c: * generic/tclResult.c: * generic/tclScan.c: * generic/tclTimer.c: * generic/tclTrace.c: * generic/tclUtil.c: * generic/tclVar.c: * unix/tclUnixFCmd.c: * unix/tclUnixPipe.c: * win/tclWinDde.c: * win/tclWinFCmd.c: * win/tclWinPipe.c: * win/tclWinReg.c: It is a poor practice to directly set or append to the value of the objResult of an interp, because that value might be shared, and in that circumstance a Tcl_Panic() will be the result. Searched for example of this practice and replaced with safer alternatives, often using the Tcl_AppendResult() routine that dkf just rehabilitated. * library/dde/pkgIndex.tcl: Bump to dde 1.3.1 * library/reg/pkgIndex.tcl: Bump to registry 1.1.5 2004-10-06 Donal K. Fellows * doc/SetResult.3: Made Tcl_AppendResult non-deprecated; better that people use it than most of the common alternatives! * generic/tclResult.c (Tcl_AppendResultVA): Make this work better with Tcl_Objs. [Patch 1041072] (Tcl_SetResult, Tcl_AppendElement): Change string to stringPtr to avoid C++ keywords. 2004-10-05 Don Porter * generic/tclBasic.c (TclObjInvoke): More simplification of the TclObjInvoke routine toward unification with the rest of the evaluation stack. * generic/tclBasic.c (Tcl_CreateInterp,Tcl_DeleteInterp, TclEvalObjvInternal,Tcl_LogCommandInfo): * generic/tclCmdAH.c (Tcl_CatchObjCmd): * generic/tclEvent.c (BgError,Tcl_BackgroundError,HandleBgErrors): * generic/tclInt.h (Interp, ERROR_CODE_SET): * generic/tclNamesp.c (Tcl_CreateNamespace,Tcl_DeleteNamespace,TclTeardownNamespace): * generic/tclResult.c (Tcl_ResetResult,Tcl_SetObjErrorCode,TclTransferResult): * generic/tclTrace.c (CallVarTraces): Reworked management of the "errorCode" 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 ::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. ***POTENTIAL INCOMPATIBILITY*** Code that sets traces on the ::errorCode variable may notice a difference in timing of the firing of those traces. * generic/tclNamesp.c (Tcl_PopCallFrame): Removed Bug 1038021 workaround. That bug is now fixed. 2004-10-04 Kevin B. Kenny * tests/clock.test (clock-34.*): Removed an antibug that forced comparison of [clock scan] results with the :localtime time zone. Now that [clock scan] uses the current time zone instead, the antibug caused several tests to fail. [Bug 1038554] 2004-10-04 Donal K. Fellows * generic/tclParseExpr.c (GetLexeme): Ensure that the 'eq' and 'ne' operators are followed by non-alphabetic characters so lexemes can't run together. [Bug 884830] * doc/DictObj.3, doc/dict.n: Clarified that a dictionary is not order-preserving. [Bug 1032243] Also added another example to show off more ways of using a dictionary and a few other formatting improvements. 2004-10-02 Donal K. Fellows * generic/tclDictObj.c (TraceDictPath, Tcl_DictObjPutKeyList): Add support for automatic creation of dictionary paths since that is what everyone seems to actually expect of the API! [Bug 1037235] (Tcl_DictObjNext): Make calling this after Tcl_DictObjDone non-fatal as that simplifies a number of internal APIs. This doesn't break any existing working code as it is a case which previously caused a panic. 2004-10-02 Don Porter * tests/namespace.test (namespace-8.7): Another test for save/restore of ::errorInfo and ::errorCode during global namespace teardown. 2004-10-01 Donal K.

It was set during interp creation and never tested. Whatever purpose it had is in the past. * generic/tclBasic.c (Tcl_EvalObjEx): Removed the flag bit value * generic/tclInt.h (Interp): USE_EVAL_DIRECT. It was used only * generic/tcLTest.c (TestevalexObjCmd): in the testing command * tests/parser.test (parse-9.2): [testevalex] and nothing in the test suite made use of the capability it enabled. * generic/tclBasic.c (Tcl_AddObjErrorInfo): More re-organization * generic/tclCmdAH.c (Tcl_ErrorObjCmd): of the management of * generic/tclCmdMZ.c (TclProcessReturn): the errorCode value. * tests/error.test (error-6.4-9): * generic/tclNamespace.c (TclTeardownNamespace): Tcl_Obj-ified * tests/namespace.test (namespace-8.5,6): the save/restore of ::errorInfo and ::errorCode during global namespace teardown.

Broke the free-form parser apart so that the Bison parser is responsible for only parsing, while clock.tcl handles relative times like "next Thursday", "next January". This change is needed to make timezones other than :localtime and :Etc/UTC work with free-form scanning. This change closes out the issue identified as being "for another day" in my log message of 2004-09-08. The refactored code also eliminates the last known references to TclpStrftime and TclGetDate, so those routines (including compat/strftime.c) have been removed. The refactoring also has the benefit that all storage in the Bison parser is now on the C stack, eliminating any need for mutex protection around [clock scan]. Also, changed the Makefiles so that 'make gendate' is available on Windows as well as Unix. * generic/tclCmdAH.c (Tcl_FormatObjCmd): Removed some grubby * generic/tclObj.c (SetBooleanFromAny): work-around code that was needed only because of Bug 868489. * generic/tclBasic.c (TclObjInvoke): Removed three unused variables to silence a compiler warning in VC++. 2004-09-27 Vince Darley * doc/FileSystem.3: fix to small typo. 2004-09-26 Miguel Sofer * generic/tclCompCmds.c: * generic/tclCompExpr.c: * generic/tclCompile.c: * generic/tclCompile.h: * generic/tclInt.h: * generic/tclProc.c: * tests/compExpr-old.test: * tests/compExpr.test: * tests/expr.test: * tests/for.test: * tests/if.test: * tests/incr.test: * tests/while.test: Report compilation errors at runtime, [Patch 1033689] by dgp. 2004-09-23 Mo DeJong * unix/dltest/Makefile.in (clean): Fixup make clean rule so that it does not delete all files when SHLIB_SUFFIX is set to the empty string in a static build.

[Routine maintenance - no bug] Spanish-language description of the change at http://www.presidencia.gub.uy/decretos/2004091502.htm 2004-09-21 Don Porter * generic/tclCompCmds.c: Tolerate [append] syntax errors * tests/appendComp.test (8.1): at compile time, and allow runtime to raise the error (or succeed if a redefined [append] allows). * generic/tclBasic.c: Reworked management of the interp * generic/tclCompile.c: flag ERR_ALREADY_LOGGED, to reduce * generic/tclExecute.c: its exposure. Still left several * generic/tclNamesp.c: references that are just too nice on performace to do away with. These changes also resolve an inconsistency in the ::errorInfo values produced by [namespace eval x error foo bar] and [namespace eval x {error foo bar}]. * generic/tclExecute.c (TclCompEvalObj): Simplified the TclCompEvalObj routine. Much housekeeping now reliably happens elsewhere. [Patch 1031949] 2004-09-21 Donal K.

This greatly reduces the number of different places in the code that need to know details about an internal bitflag field of the Interp struct. Also places errorCode setting in one place for easier future mods. 2004-09-17 Kevin B.Kenny * generic/tclDate.c: Revised tclGetDate.y to use bison instead * generic/tclGetDate.y: of yacc to build the parser, eliminating * generic/tclInt.h: all the complicated hackery involving * unix/Makefile.in: 'sed' postprocessing. Rebuilt the parser. 2004-09-14 Kevin B. Kenny * generic/tclClock.c (ClockOldscanObjCmd): Silenced a compiler warning (long passed as a param where unsigend long was expected). 'Unsigned long' is wrong, but the fix is really to change the signature of TclGetDate to return a structure of its 'yy' variables and then do the remaining work inside clock.tcl. But, as I said on 2004-09-08, that's a job for another day.

TCL_NAMESPACE_ONLY now acts as specified in the pre-function comment, forcing resolution in the passed in context namespace. It has been incorrectly forcing resolution in the interp's current namespace. 2004-09-10 Kevin Kenny * library/clock.tcl: Fixed a bug where %z always put a plus sign on the time zone in :localtime. * tests/clock.test: Added test case for the above bug. 2004-09-10 Miguel Sofer * generic/tclExecute.c (INST_CONCAT1): added a peephole optimisation for concatting an empty string. This enables replacing the idiom 'K $x [set x {}]' by '$x[set x {}]' for fastest execution. 2004-09-09 David Gravereaux * win/tclWinConsole.c: Calls to WriteFile and WriteConsoleA changed to WriteConsole for simplicity. 2004-09-09 Don Porter * generic/tclNamesp.c (Tcl_ForgetImport): Corrected faulty * tests/namespace.test: logic that relied exclusively on string matching and failed in the presence of [rename]s. [Bug 560297] Also corrected faulty prevention of [namespace import] cycles. [Bug 1017299] 2004-09-08 Don Porter * generic/tclBasic.c (Tcl_CreateInterp): Removed obsolete field for storing the string-based command procedure of built-in commands. We no longer have any string-based built-in commands! 2004-09-08 Kevin B. Kenny * compat/strftime.c (_conv): Corrected a problem where hour 0 would format as a blank format group with %k. * doc/clock.n: Corrected a buglet in the header information. [Bug 1024058] * generic/tclClock.c (TclClockMktimeObjCmd): Fixed a bug where the month was scanned incorrectly in -timezone :localtime. * tests/clock.test (clock-34.*,clock-40.1, clock-41.1): Adjusted the clock-34.* test cases so that the consistency check is performed in :localtime rather than the current time zone. This change allows dealing with issues where the C library has a different idea of DST conversion than Tcl. (Real fix would be to break TclGetDate into separate parser and time converter, and do the time conversion in clock.tcl. That's for another day.) Added regression test case for the bug where month was scanned incorrectly in -timezone :localtime. [Bug 1023779] Added regression test case for %k at the zero hour. 2004-09-07 David Gravereaux * win/makefile.vc: some quoting needed to be removed as it was breaking with VC7. [Bug 1023150] 2004-09-07 Kevin B. Kenny * doc/clock.n: Documented the default -format, and changed references to a (nonexistent) msgcat command to refer to the msgcat package. [Bug 1023870] * generic/tclTimer.c: Removed a premature optimisation that attempted to store the assoc data in the client data; the optimisation caused a bug that [after] would overwrite its imports. [Bug 1016167] * library/clock.tcl (InitTZData, ClearCaches): Changed so that the in-memory time zone :UTC (and its aliases) always gets reinitialised, in case tzdata is absent. [Bug 1019537, 1023779] * library/tzdata/*: Regenerated. * tests/clock.test (clock-31.*, clock-39.1): Corrected a problem where the 'system' locale tests fail on a non-English Windows machine. [Bug 1023761]. Added a test to make sure that alias time zones load correctly. [Bug 1023779]. * tests/timer.test (timer-1.1, timer-2.1): Changed to (one hopes!) be more resilient on an overloaded system, if [after 200] sleeps for 300 ms or longer. * tools/tclZIC.tcl (writeLinks): Corrected a problem where alias time zone names were written incorrectly, causing them to fail to load at run time. [Bug 1023779]. * win/tclWinTime.c (Tcl_GetTime): Eliminated CPUID tests on Win64 - assuming that HAL vendors now do a better job of keeping the performance counters synchronized among CPU's.

Fellows * generic/tclNamesp.c (FindEnsemble): Factor out the code to convert a command name into an ensemble configuration and add support for ignoring [namespace import] link chains. [Bug 1017022] (NamespaceWhichCmd): Rework to use newer option parsing API. 2004-08-27 Daniel Steffen * unix/Makefile.in: added customization of default module path roots via TCL_MODULE_PATH makefile variable. * macosx/Makefile: add platform standard locations to default module path roots. [Patch 942881] * tests/env.test: macosx fixes. 2004-08-25 Don Porter * tests/timer.test (timer-10.1): Test for Bug 1016167. * generic/tclTimer.c: Workaround for situation when a [namespace import] causes the objv[0] value to be something other than what Tcl_AfterObjCmd expects. [Bug 1016167]. 2004-08-25 Donal K. Fellows * generic/tclNamesp.c (NsEnsembleImplementationCmd): Use the ensemble command token to get the name of the ensemble for passing to the -unknown handler instead of relying on objv[0], which may contain useless info in the presence of [namespace import]. Problem found by Don Porter when investigating [Bug 1016167]. 2004-08-24 Don Porter * generic/tclProc.c: The routine TclProcInterpProc was a * generic/tclTestProcBodyObj.c: specific instance of the general service already provided by TclObjInvokeProc. Removed TclProcInterpProc and TclGetInterpProc from the code... * generic/tclInt.decls ...and from the internal stubs table. * generic/tclIntDecls.h * generic/tclStubInit.c 2004-08-24 Donal K.

[RFE 695441] 2004-08-21 Kevin B. Kenny * tests/clock.test (clock-38.1): Changed TZ setting to specify CET in excruciating detail to deal with systems that lack the Posix defaults for DST changes (and to be formally correct with the change dates for CET). 2004-08-19 Donal K. Fellows * generic/tclScan.c (Tcl_ScanObjCmd, ValidateFormat): Ensure that the %ld conversion works correctly on 64-bit platforms. [Bug 1011860] 2004-08-19 Kevin Kenny * library/clock.tcl (format): Changed default timezone format from alphabetic to numeric to produce scannable times in more locales. * tests/clock.test (clock-37.1): Removed now-unused 'needPST' constraint and the comments that refer to it. 2004-08-18 Andreas Kupries * library/init.tcl: Integrated TIP #189. We source a separate file (see below), instead of inlining the contents of that file. This should beeasier to maintain, and easier to backport/install in 8.4 installations. Note: Usage of Tcl Modules is restricted to non-safe interps. It cannot be loaded into a safe interp. * library/tm.tcl: New file, the v2 reference implementation for TIP #189, Tcl Modules. * doc/tm.n: New file, documentation for Tcl Modules, based on the TIP. * unix/mkLinks: Regenerated. * win/makefile.vc: Added tm.tcl to list of files to install. 2004-08-18 Kevin Kenny * tests/httpd (httpdRespond): Corrected an abuse of the [clock] command that caused test failures for some values of [clock clicks]. * doc/clock.n * generic/tclBasic.c (Tcl_CreateInterp, Tcl_HideUnsafeCommands): * generic/tclClock.c (all): * generic/tclInt.h: * generic/tclInterp.c (CreateSlave): * library/clock.tcl: (new file) * library/init.tcl (clock): * library/msgs/*.msg:(new files) * library/tzdata/*: * library/tzdata/*/*: * library/tzdata/*/*/*: (new files) * tools/installData.tcl: (new file) * tools/loadICU.tcl: (new file) * tools/makeTestCases.tcl: (new file) * tools/tclZIC.tcl: (new file) * unix/Makefile.in: * unix/configure: (regenerated) * unix/tcl.m4: * tests/clock.test (all): * win/Makefile.in: * win/Makefile.vc: Implementation of TIPs #173 and #209. The [clock] command is now a Tcl ensemble, with most of its functionality written in Tcl and callouts to C code only to access low-level functions such as localtime, mktime and tzset. In addition to the functionality changes called out in the two TIPs, it is worth noting that the [clock] command in a safe slave interpreter is now an alias to the [clock] command in the master, and that [clock] is otherwise not expected to function entirely correctly in safe interps. C code that simply does Tcl_MakeSafe needs to be aware that [clock] may need special handling. (It appears unlikely that such code actually exists.) One incompatibility of note is that if the time zone cannot be determined from the TZ, TCL_TZ environment variables, or from the Windows control panel, so that the C library must be used for date and time conversions, then times outside the range of time_t will fail; they used to return bad data silently.

This change corrects a number of memory mismanagement issues in the cases where the internal representation of one literal contains a reference to another, and avoids conditions such as resolved variable names referring to procedure and namespace contexts that no longer exist. [Bug 994838] 2004-07-20 Daniel Steffen * unix/Makefile.in: * win/Makefile.in: added 'install-private-headers' makefile target to allow optionally installing private tcl headers.

They were not destroyed properly upon finalization. 2004-07-15 Andreas Kupries * generic/tclIO.h (CHANNEL_INCLOSE): New flag. Set in * generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the * generic/tclIO.c (Tcl_Close): close callbacks are run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent recursive call of 'close' in the close-callbacks. This is a possible error made by implementors of virtual filesystems based on 'tclvfs', thinking that they have to close the channel in the close handler for the filesystem. 2004-07-14 Andreas Kupries * generic/tclIO.c: * generic/tclIO.h: * Not reverting, but #ifdef'ing the changes from May 19, 2004 out of the core. This removes the ***POTENTIAL INCOMPATIBILITY*** for channel drivers it introduced. This has become possible due to Expect gaining a BlockModeProc and now handling blockingg and non-blocking modes correctly. Thus [SF Tcl Bug 943274] is still fixed if a recent enough version of Expect is used. * doc/CrtChannel.3: Added warning about usage of a channel without a BlockModeProc. 2004-07-15 Andreas Kupries * generic/tclIOCmd.c (Tcl_PutsObjCmd): Added length check to the old depreceated newline syntax, to ensure that only "nonewline" is accepted. [Tcl SF Bug 985869], reported by Joe Mistachkin . 2004-07-15 Zoran Vasiljevic * generic/tclEvent.c (Tcl_Finalize): stuffed memory leak incurred by re-initializing of TSD slots after the last call to TclFinalizeThreadData (done from within Tcl_FinalizeThread()). We basically just repeat the TclFinalizeThreadData() once more before tearing down TSD keys in TclFinalizeSynchronization(). There should be more elaborate mechanism in place for handling such issues, based on thread cleanup handlers registered on the OS level. Such change requires much more work and would also require TIP because some visible parts of Tcl API would have to be modified. In the meantime, this will do. * generic/tclNotify.c (TclFinalizeNotifier): Added conditional notifier finalization based on the fact that an TclInitNotifier has been called for the current thread. This fixes the Tcl Bug #770053 again. Hopefully this time w/o unwanted side-effects. 2004-07-15 Kevin Kenny * generic/tclLiteral.c (TclReleaseLiteral): Removed unused variable 'codePtr' to silence a message from VC++. 2004-07-15 Miguel Sofer * generic/tclCompile.c (TclCompileScript): * generic/tclLiteral.c (TclReleaseLiteral): fix for [Bug 467523], which resurfaced with the latest changes. The previous strategy was to have special code in TclReleaseLiteral to handle the self-references generated by empty scripts. The new approach avoids the self-reference altogether, by having empty scripts return an unshared literal. 2004-07-15 Zoran Vasiljevic * generic/tclEvent.c (NewThreadProc): Backout of changes to fix the Tcl Bug #770053. See SF bugreport for more info. 2004-07-11 Miguel Sofer * generic/tclBasic.c (Tcl_EvalEx): leak fix by dgp, release objv[objectsUsed] on error. 2004-07-11 Miguel Sofer * generic/tclParse.c (Tcl_SubstObj): leak fix by dgp, release result on error. 2004-07-11 Donal K.

[Bug 989093 in part] 2004-07-11 Miguel Sofer * generic/tclExecute.c (TEBC): fixed leak of expandNestList objs when there is an error while an expansion is in progress (code added at checkForCatch). 2004-07-11 Vince Darley * generic/tclIOUtil.c: fix to 'cd' bug when vfs is active [Bug 986944 in tclvfs project] - this bug recently introduced by some threading fixes. Need to work out how to add tests for this. 2004-07-10 Kevin Kenny * tests/clock.test (clock-2.11): Changed the test so that it isn't an infinite loop when run under valgrind on a slow virtual machine. Thanks to Miguel Sofer for the bug report. Also put in code to restore env(LC_TIME) after tests complete, silencing a warning from 'make TESTFLAGS="-debug 1" test'. 2004-07-08 Miguel Sofer * generic/tclBasic.c (DeleteInterpProc): reverted the modification of 3 days ago, as the leak of [Bug 983660] is now handled by the change in TclCleanupByteCode. * generic/tclCompile.c (TclCleanupByteCode): let each bytecode remove its references to literals at interp deletion, without updating the dying literal table. * generic/tclLiteral.c (TclDeleteLiteralTable): with the above change to TclCleanupByteCode, this function now removes a single reference to the literal object and cleans up its own structures. 2004-07-08 Kevin Kenny * win/tclWinInit.c (AppendEnvironment): Silenced a compilation warning about a type mismatch. 2004-07-07 Miguel Sofer * generic/tclCompile.c (TclCompileScript): fix for [Bug 458361]. Single-word scripts are compiled with an unshared cmdName to avoid shimmering between bytecode and cmdName reps. 2004-07-07 Don Porter * generic/tclCmdMZ.c (TclMergeReturnOptions): Simplified logic and removed potential memory leak.

Tear down the global namespace before freeing the interp handle, to allow the bytecodes to free their non-shared literals. * generic/tclLiteral.c (TclReleaseLiteral): moved special code for self-ref so that it is also used for non-shared literals. Possible bug found by inspection. 2004-07-03 Miguel Sofer * generic/tclExecute.c (ExprRoundFunc): * tests/expr-old.test (39.1): added support for wide integers to round(); [Bug 908375], reported by Hemang Lavana. 2004-07-03 Miguel Sofer * generic/tclCompile.h: * generic/tclInt.decls: * generic/tclIntDecls.h: * generic/tclStubInit.c: Moved declaration of TclCompEvalObj() from tclCompile.h to the internal stubs table, for compiler experimentation. 2004-07-02 Jeff Hobbs * generic/regcomp.c (stid): correct minor pointer size error * generic/tclPipe.c (TclCreatePipeline): applied TIP #202 patch * doc/exec.n, tests/exec.test: that adds 2>@1 as a special case redirection of stderr to the result output. 2004-07-02 Kevin B.

Fellows TIP#188 IMPLEMENTATION * doc/string.n, tests/string.test: Add 'wideinteger' to things * generic/tclCmdMZ.c (Tcl_StringObjCmd): that can be tested for with the [string is] subcommand. [Patch 940915, by Kevin Kenny] 2004-06-29 Don Porter * win/tclWinInit.c: Corrected reference counting flaw in recent changes. Thanks to Pat Thoyts. [Bug 981893]. 2004-06-29 Vince Darley * win/tclWin32Dll.c: fix to compilation with VC++ 5.2 2004-06-29 Donal K. Fellows * library/safe.tcl: Make sure that the temporary variable is local to the namespace and not inadvertently global. [Bug 981733] 2004-06-24 Donal K. Fellows * tests/unixNotfy.test: Modified constraints so that testing with a threaded tclsh (not tcltest) will not hang. 2004-06-23 Don Porter * generic/tclThreadStorage.c: Corrected type casting errors that led to calculation of a negative index value, thus accesses outside the threadStorageCache array, thus memory corruption. Crash observed on Mac OS X platform. 2004-06-23 Joe Mistachkin * generic/tclThread.c: Implements platform independent thread storage * generic/tclThreadStorage.c: mechanism and fixes associated bugs on platforms where there is limited thread local storage space (Win98/WinNT4). [Patch 976496] * generic/tclInt.decls: * generic/tclIntDecls.h: Added thread storage functions to the * generic/tclStubInit.c: internal stubs table. * unix/Makefile.in: * unix/configure: * unix/tcl.m4: * win/makefile.vc: * win/rules.vc: * win/Makefile.in: Modified the unix, VC++, and Cygwin build systems * win/configure: to include the new "tclThreadStorage.c" and the new * win/tcl.m4: USE_THREAD_STORAGE define. 2004-06-23 Pat Thoyts * tests/io.test: Added -force to 18.1 and 18.2. This was failing on WinXP. * tests/winFCmd.test: Added a cleanup to winFCmd-16.11 to avoid a failure in 16.12. * tests/eofchar.data: Added -kb option to ensure a binary checkout to win32 systems. This fixes a failure in io-61.1 * win/makefile.vc: fix for bug #977369 about launching tclsh to generate a tclConfig.sh with the nmake build system 2004-06-23 Kevin B. Kenny * tests/winDde.test (createChildProcess): Added a 200-ms delay (with the event loop live) when shutting down the test DDE server process, With the delay in place, nuisance failures of tests winDde-4.2, -6.5, and -6.6 appear to be much less frequent. [Bug #957449] 2004-06-23 Donal K. Fellows * tests/*.test: Standardize use of platform constraints. * unix/tclUnixInit.c (GetStackSize, TclpCheckStackSpace): * unix/tclUnixThrd.c (TclpThreadGetStackSize): Added code to check whether the C stack is about to be exceeded, from [Patch 746378] by Joe Mistachkin but with substantial revisions. 2004-06-22 Kevin Kenny * generic/tclEvent.c (NewThreadProc): Fixed broken build on Windows caused by missing TCL_THREAD_CREATE_RETURN. * tests/stack.test (stack-3.1): Corrected nuisance error in threaded builds. 2004-06-22 Zoran Vasiljevic * generic/tclEvent.c: * generic/tclInt.h: * unix/tclUnixNotfy.c: * unix/tclUnixThrd.c: * win/tclWinThrd.c: [Bug #770053]. See bug report for more information about what it does. * tests/unixNotfy.test: rewritten to use tcltest::threadReap to gracefully wait for the test thread to exit. Otherwise we got a race condition with main thread exiting before the test thread. This exposed the long-standing Tcl lib issue with resource garbage-collection on application exit. 2004-06-21 Mo DeJong * win/tclWin32Dll.c (DllMain, _except_dllmain_detach_handler, TclpCheckStackSpace, _except_checkstackspace_handler, TclWinCPUID, _except_TclWinCPUID_detach_handler): * win/tclWinChan.c (Tcl_MakeFileChannel, _except_makefilechannel_handler): * win/tclWinFCmd.c (DoRenameFile, _except_dorenamefile_handler, DoCopyFile, _except_docopyfile_handler): Rework pushing of exception handler function pointer so that compiling with gcc -O3 works. Remove empty function call to avoid compiler warning. Mark the DllMain function as noinline to avoid compiler error from duplicated asm labels in generated code. 2004-06-21 Donal K. Fellows * generic/tclThreadAlloc.c (Ptr2Block): Rewrote so as to maximize the chance of detecting and reporting a memory inconsistency without relying on things being consistent. [Bug 975895] 2004-06-18 Don Porter * tests/load.test: Relaxed strictness of error message matching for test load-2.3 so that it will pass on Mac OSX. * generic/tclEncoding.c: Static TclFindEncodings -> FindEncodings. * generic/tclInt.h: Updated TclpFindExecutable() so that failed * generic/tclUtil.c: attempts to find the executable are saved * unix/tclUnixFile.c: just as successful finds are. [Patch 966053] * unix/tclUnixTest.c: 2004-06-18 Kevin B. Kenny * tests/winFCmd.test (winFCmd-16.12): Changed test to compute the target directory, so as not to fail if the user's HOME isn't the root. 2004-06-19 Daniel Steffen * unix/tcl.m4: autoconf 2.5 fixes in Darwin section. * unix/configure: autoconf-2.57 2004-06-18 Donal K. Fellows * unix/tclUnixInit.c (localeTable): Added some more locale to encoding mapping info from Jim Huang * generic/tclInt.h (PendingObjData,TclFreeObjMacro,etc): * generic/tclObj.c (TclFreeObj): Added scheme for making TclFreeObj() avoid blowing up the C stack when freeing up very large object trees. [Bug 886231] * win/tclWinInit.c (SetDefaultLibraryDir): Fix logic, simplify and add comments. 2004-06-17 Don Porter * generic/tclObj.c: Added missing space in panic message. * win/tclWinInit.c: Inform [tclInit] about the default library directory via the ::tclDefaultLibrary variable. This should correct a problem with my 2004-06-11 commit. Better solutions still in the works. Thanks to Joe Mistachkin for pointing out the breakage. 2004-06-16 Don Porter * doc/library.n: Moved variables ::auto_oldpath and * library/auto.tcl: ::unknown_pending into ::tcl namespace. * library/init.tcl: [Bugs 808319, 948794] 2004-06-15 Donal K. Fellows * doc/binary.n: Added some notes to the documentation of the 'a' format to address the point raised in [RFE 768852]. 2004-06-15 Jeff Hobbs * unix/tclConfig.sh.in (TCL_EXTRA_CFLAGS): set to @CFLAGS@, which is the configure-time CFLAGS. Addendum to m4 change on 2004-05-26. 2004-06-14 Kevin Kenny * win/Makefile.in: Corrected compilation flags for tclPkgConfig.c so that it doesn't require Stubs. * generic/tclBasic.c (Tcl_CreateInterp): Removed comment stating that TclInitEmbeddedConfigurationInformation needs Stubs; with the change above, the comment is now erroneous. 2004-06-11 Don Porter * doc/Encoding.3: Removed bogus claims about tcl_libPath. * generic/tclInterp.c (Tcl_Init): Stopped setting the tcl_libPath variable. [tclInit] can get all its directories without it. * tests/unixInit.test: Modified test code that made use of tcl_libPath variable. * unix/tclUnixInit.c: Stopped setting the tclDefaultLibrary variable, execept on the Mac OS X platform with HAVE_CFBUNDLE. In that configuration we should seek some way to make use of the TIP 59 facilities and get rid of that usage of tclDefaultLibrary as well. * generic/tclInterp.c: Updated [tclInit] to make $env(TCL_LIBRARY) an absolute path, and to include the scriptdir,runtime configuration value on the search path for init.tcl. * unix/tclUnixInit.c: The routines Tcl_Init() and TclSourceRCFile() * win/tclWinInit.c: had identical implementations for both win and * generic/tclInterp.c: unix. Moved to a single generic implementation. * generic/tclMain.c: * library/init.tcl: * generic/tclInitScript.h (removed): * unix/Makefile.in: * win/tcl.dsp: * unix/configure.in: Updated TCL_PACKAGE_PATH value to * win/configure.in: handle --libdir configuration. * unix/configure.in: autoconf-2.57 * win/configure.in: * generic/tclBasic.c (Tcl_CreateInterp): Moved call to TclInitEmbeddedConfigurationInformation() earlier in Tcl_CreateInterp() so that other parts of interp creation and initialization may access and use the config values. 2004-06-11 Kevin Kenny * win/tclAppInit.c: Restored the 'setargv' procedure when compiling with mingw. Apparently, the command line parsing in mingw doesn't work as well as that in vc++, and the result was (1) that winPipe-8.19 failed, and (2) that 'make test' would work at all only with TESTFLAGS='-singleproc 1'. [Bug 967195] 2004-06-10 Zoran Vasiljevic * generic/tclIOUtil.c: removed forceful setting of the private cached current working directory rep from within the Tcl_FSChdir(). We delegate this task to the Tcl_FSGetCwd() which does this task anyway. The relevant code is still present but disabled temporarily until the change proves correct. The Tcl test suite passes all test with the given change so I suppose it is good enough. 2004-06-10 Don Porter * unix/tclUnixInit.c (TclpInitLibraryPath): Disabled addition of * win/tclWinInit.c (TclpInitLibraryPath): relative-to-executable directories to the library search path. A first step in reform of Tcl's startup process. ***POTENTIAL INCOMPATIBILITY*** Attempts to directly run ./tclsh or ./tcltest out of a build directory will either fail, or will make use of an installed script library in preference to the one in the source tree. Use `make shell` or `make runtest` instead. * tests/unixInit.test: Modified tests to suit above changes. * generic/tclPathObj.c: Corrected [file tail] results when operating on a path produced by TclNewFSPathObj(). [Bug 970529] 2004-06-09 Zoran Vasiljevic * generic/tclIOUtil.c: partially corrected [Bug 932314]. Also, corrected return values of Tcl_FSChdir() to reflect those of the underlying platform-specific call. Originally, return codes were mixed with those of Tcl. 2004-06-08 Miguel Sofer * generic/tclCompile.c: * generic/tclExecute.c: handle warning [Bug 969066] 2004-06-08 Donal K. Fellows * generic/tclHash.c (RebuildTable): Move declaration of variable so it is only declared when it is used. [Bug 969068] 2004-06-07 Donal K. Fellows * doc/lsearch.n: Added correct option to example. [Bug 968219] 2004-06-05 Kevin B. Kenny * generic/tcl.h: Corrected Tcl_WideInt declarations so that the mingw build works again. * generic/tclDecls.h: Changes to the tests for * generic/tclInt.decls: clock frequency in * generic/tclIntDecls.h: Tcl_WinTime * generic/tclIntPlatDecls.h: so that any clock frequency * generic/tclPlatDecls.h: is accepted provided that * generic/tclStubInit.c: all CPU's in the system share * tests/platform.test (platform-1.3): a common chip, and hence, * win/tclWin32Dll.c (TclWinCPUID): presumably, a common clock. * win/tclWinTest.c (TestwincpuidCmd) This change necessitated a * win/tclWinTime.c (Tcl_GetTime): small burst of assembly code to read CPU ID information, which was added as TclWinCPUID in the internal Stubs. To test this code in the common case of a single-processor machine, a 'testwincpuid' command was added to tclWinTest.c, and a test case in platform.test. Thanks to Jeff Godfrey and Richard Suchenwirth for reporting this bug. [Bug #976722] 2004-06-04 Don Porter * generic/tcl.h: Restored #include to tcl.h, rejecting the "fix" for "Bug" 945570. Tcl_FSSeek() needs the values of SEEK_SET, etc. and too many extensions rely on tcl.h providing stdio.h for them. 2004-06-02 Jeff Hobbs * win/tclWinFile.c (TclpFindExecutable): when using GetModuleFileNameA (Win9x), convert from CP_ACP to WCHAR then convert back to utf8. Adjunct to 2004-04-07 fix. 2004-06-02 David Gravereaux * tests/winPipe.test (winpipe-6.1): blocking set to 1 before closing to ensure we get an exitcode. The windows pipe channel driver doesn't differentiate between a blocking and non-blocking close just yet, but will soon. Part of [Bug 947693] 2004-06-02 Vince Darley * doc/file.n: fix to documentation of 'file volumes' (Bug 962435) 2004-06-01 David Gravereaux * win/makefile.vc: check for either MSDEVDIR or MSVCDIR being in the environment, for VC7. [Bug 942214] * generic/tclIO.c (Tcl_SetChannelOption): -buffersize wasn't understanding hexidecimal notation nor was reporting number conversion errors. The behavior to silently ignore settings outside the acceptable range of Tcl_SetChannelBufferSize (<10 or >1M) is unchanged. This silent ignoring behavior might be up for review soon.. 2004-05-30 David Gravereaux * win/tclWinPipe.c: * win/tclWinPort.h: Reworked the win implementation of Tcl_WaitPid to support exitcodes in the 'signed short' range. Even though this range is non-portable, it is valid on windows. Detection of exception codes are now more accurate. Previously, an application that exited with ExitProcess((DWORD)-1); was improperly reported as exiting with SIGABRT. 2004-05-30 Donal K. Fellows * generic/tclInterp.c: Added comments describing the purposes of each function in the limit implementation and rewrote the names of some non-public functions for greater clarity of purpose. * doc/interp.n: Added note about what happens when a limited interpreter creates a slave interpreter. * doc/Limit.3: Added manual page for the resource limit subsystem's C API. [Bug 953903] 2004-05-29 Joe English * doc/global.n, doc/interp.n, doc/lrange.n: Fix minor markup errors. 2004-05-28 Donal K. Fellows * doc/*.n: Added examples to many (too many to list) more man pages. 2004-05-25 Miguel Sofer * generic/tclExecute.c: * generic/tclVar.c: using (ptrdiff_t) instead of (int) casting to correct compiler warnings [Bug 961657], reported by Bob Techentin. 2004-05-27 Kevin B. Kenny * tests/clock.test: Added a single test for the presence of %G in [clock format], and conditioned out the clock-10.x series if they're all going to fail because of a broken strftime() call. [Bug 961714] 2004-05-27 Donal K. Fellows * generic/tclHash.c (CompareStringKeys): Added #ifdef to allow people to instruct this function to use strcmp(). [FRQ 951168] * generic/tclVar.c: Moved declarations into #if guards so they only happen when required. * unix/tclUnixPort.h: Guard declaration of strtod() so it is only enabled when we don't have a declaration in stdlib.h * unix/tclUnixThrd.c (Tcl_CreateThread): Added declarations * unix/tclUnixTest.c (AlarmHandler): and casts so that * unix/tclUnixChan.c (TtyModemStatusStr): all functions are * generic/tclScan.c (Tcl_ScanObjCmd): defined before use * generic/tclDictObj.c (InvalidateDictChain): and no cross-type * generic/tclCmdMZ.c (Tcl_StringObjCmd): uses are performed. The overall effect is to make building with gcc with the additional flags -Wstrict-prototypes -Wmissing-prototypes produce no increase in the total number of warnings (except for main(), which is undeclared for traditional reasons.) 2004-05-26 Jeff Hobbs * unix/Makefile.in: Rework configure ordering to TCL_LINK_LIBS, * unix/tcl.m4: ENABLE_SHARED, CONFIG_CFLAGS, & ENABLE_SYMBOLS * unix/configure: before TCL_EARLY_FLAGS and TCL_64BIT_FLAGS * unix/configure.in: (about 400 lines earlier) in configure.in. This forces CFLAGS configuration to be done before many tests, which is needed for 64-bit builds and may affect other builds. Also make CONFIG_CFLAGS append to CFLAGS directly instead of using EXTRA_CFLAGS, and have LDFLAGS append to any existing value. [Bug #874058] * unix/dltest/Makefile.in: change EXTRA_CFLAGS to DEFS 2004-05-26 Don Porter * library/tcltest/tcltest.tcl: Correction to debug prints and testing * library/tcltest/pkgIndex.tcl: if TCLTEST_OPTIONS value. Corrected * tests/tcltest.test: double increment of numTestFiles in -singleproc 1 configurations. Updated tcltest-19.1 to tcltest 2.1 behavior. Corrected tcltest-25.3 to not falsely report a failure in tcltest.test. Bumped to tcltest 2.2.6. [Bugs 960560, 960926] 2004-05-25 Jeff Hobbs * doc/http.n (http::config): add -urlencoding option (default utf-8) * library/http/http.tcl: that specifies encoding conversion of * library/http/pkgIndex.tcl: args for http::formatQuery. Previously * tests/http.test: undefined, RFC 2718 says it should be utf-8. 'http::config -urlencoding {}' returns previous behavior, which will throw errors processing non-latin-1 chars. Bumped http package to 2.5.0. 2004-05-25 Donal K. Fellows * generic/tclInterp.c (DeleteScriptLimitCallback): Move all deletion of script callback hash table entries to happen here so the entries are correctly removed at the right time. [Bug 960410] 2004-05-25 Miguel Sofer * docs/global.n: added details for qualified variable names [Bug 959831] 2004-05-25 Miguel Sofer * generic/tclNamesp.c (Tcl_FindNamespaceVar): * tests/namespace.test (namespace-17.10-12): reverted commit of 2004-05-23 and removed the tests, as it interferes with the varname resolver and there are apps that break (AlphaTk). A fix will have to wait for Tcl9. * generic/tclVar.c: Caching of namespace variables disabled: no simple way was found to avoid interfering with the resolver's idea of variable existence. A cached varName may keep a variable's name in the namespace's hash table, which is the resolver's criterion for existence. * tests/namespace.c (namespace-17.10): testing for interference between varname caching and name resolver. 2004-05-25 Kevin Kenny * tests/winFCmd.test: Correct test for the presence of a CD-ROM so that it doesn't misdetect some other sort of filesystem with a write-protected root as being a CD-ROM drive. [Bug 918267] 2004-05-25 Don Porter * tests/winPipe.test: Protect against path being set * tests/unixInit.test: Unset path when done. * tests/unload.test (unload-3.1): Verify [pkgb_sub] does not exist. Delete interps when done. * tests/stringComp.test: stop re-use of string.test test names * tests/regexpComp.test: stop re-use of regexp.test test names * tests/namespace.test (namespace-46.3): Verify [p] does not exist. * tests/http.test: Clear away the custom [bgerror] when done. * tests/io.test: Take care to use namespace variables. * tests/autoMkindex.test (autoMkindex-5.2): Use variable "result" that gets cleaned up. * tests/exec.test: Clean up the "path" array. * tests/interp.test (interp-9.3): Initialize res, so prior values cannot make the test fail. * tests/execute.test (execute-8.1): Updated to remove the trace set on ::errorInfo . When left in place, that trace can cause later tests to fail. 2004-05-25 Donal K. Fellows * generic/tclBasic.c: Removed references to Tcl_RenameCommand from * generic/tcl.h: comments. [Bug 848440, second part] * tests/fCmd.test: Rewrote tests that failed consistently on NFS so they either succeed (through slightly more liberal matching of the results) or are constrained to not run. [Bug 931312] * doc/bgerror.n: Use idiomatic open flags for working with log files. [Bug 959602] 2004-05-24 Jeff Hobbs * generic/tclExecute.c (VerifyExprObjType): use GET_WIDE_OR_INT to properly have tclIntType used for smaller values. This corrects TclX bug 896727 and any other 3rd party extension that created math functions but was not yet WIDE_INT aware in them. 2004-05-24 Donal K. Fellows * generic/tclInterp.c (TclInitLimitSupport): Made limits work on platforms where sizeof(void*)!=sizeof(int). [Bug 959193] 2004-05-24 Miguel Sofer * doc/set.n: accurate description of name resolution process, referring to namespace.n for details [Bug 959180] 2004-05-23 Miguel Sofer * generic/tclNamesp.c (Tcl_FindNamespaceVar): [Bug 959052] fixed, insuring that no "zombie" variables are found. * generic/tclVar.c (TclLookupSimpleVar): comments re [Bug 736729] (predecessor of [Bug 959052]) removed. * tests/namespace.test: added tests 17.10-12 The patch modifies non-documented behaviour, and passes every test in the testsuite. However, scripts relying on the old behaviour may break. Note that the only behaviour change concerns the creative writing of unset variables. More precisely, which variable will be created when neither a namespace variable nor a global variable by that name exists, as defined by [info vars]. The new behaviour is that the namespace resolution process deems a variable to exist exactly when [info vars] finds it - ie, either it has value, or else it was "fixed" by a call to [variable]. Note: this patch was removed on 2002-05-25. 2004-05-22 Miguel Sofer * generic/tclVar.c (TclObjLookupVar, TclObjUnsetVar2): fix for new (in tcl8.4) exteriorisations of [Bug 736729] due to the use of tclNsVarNameType obj types. Reenabling the use of this objType ("VAR ref absolute" benchmark down to 66 ms, from 230). Added comments in TclLookupSimpleVar explaining my current understanding of [Bug 736729]. 2004-05-22 Miguel Sofer * generic/tclVar.c: fix for [Bug 735335]. The use of tclNsVarNameType objs is still disabled, pending resolution of [Bug 736729]. 2004-05-21 Miguel Sofer * tests/namespace.test (namespace-41.3): removed the {knownBug} constraint: [Bug 231259] is closed since nov 2001, and the fix of [Bug 729692] (INST_START_CMD) makes the test succeed. 2004-05-21 Donal K. Fellows * generic/tclExecute.c (TclExecuteByteCode): Move a few declarations a short distance so pre-C99 compilers can cope. Also fix so TCL_COMPILE_DEBUG path compiles... 2004-05-21 Miguel Sofer * generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC automatic variables, defining them in tight blocks instead of at the function level. This has three purposes: - it simplifies the analysis of individual instructions - it is preliminary work to the non-recursive engine - it allows a better register allocation by the optimiser; under gcc3.3, this results in up to 10% runtime in some tests 2004-05-20 Donal K. Fellows * generic/tclInterp.c (TclLimitRemoveAllHandlers): * generic/tclBasic.c (DeleteInterpProc): * tests/interp.test (interp-34.7): Ensure that all limit callbacks are deleted when their interpreters are deleted. [Bug 956083] 2004-05-19 Kevin B. Kenny * win/tclWinFile.c (TclpMatchInDirectory): fix for an issue where there was a sneak path from Tcl_DStringFree to SetErrorCode(0). The result was that the error code could be reset between a call to FindFirstFileEx and the check of its status return, leading to a bizarre error return of {POSIX unknown {No error}}. (Found in unplanned test - no incident logged at SourceForge.) 2004-05-19 Donal K. Fellows * tests/interp.test (interp-34.3): Rewrite this test to see if a time limit can catch a tight bytecode loop, a maximally aggressive denial-of-service attack. * generic/tclInterp.c (Tcl_LimitCheck): Fix the sense of checks to see whether a time limit has been extended. * tests/*.test: Many minor fixes, including ensuring that every test is run (so constraints control whether the test is doing anything) and making sure that constraints are always set using the API instead of poking around inside tcltest's internal datastructures. Also got rid of all trailing whitespace lines from the test suite! 2004-05-19 Andreas Kupries * generic/tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem * generic/tclIO.h: as [SF Tcl Bug 462317], see ChangeLog entry 2001-09-26. The fix done at that time is incomplete. It is possible to get around it if the actual read operation is defered and not executed in the event handler itself. Instead of tracking if we are in an read caused by a synthesized fileevent we now track if the OS has delivered a true event = actual data and bypass the driver if a read finds that there is no actual data waiting. The flag is cleared by a short or full read. ***POTENTIAL INCOMPATIBILITY*** for channel drivers. 2004-05-17 Vince Darley * generic/tclPathObj.c: fix to (Bug 956063) in 'file dirname'. * tests/cmdAH.test: added test for this bug. * doc/FileSystem.3: better documentation of refCount requirements of some FS functions (Bug 956126) 2004-05-19 Donal K. Fellows * generic/tclTest.c (TestgetintCmd): Made the tests in get.test check * tests/get.test: Tcl_GetInt() since the core now avoids that function. 2004-05-18 Kevin B. Kenny * compat/strftime.c (_fmt, ISO8601Week): * doc/clock.n: * tests/clock.test: Major rework to the handling of ISO8601 week numbers. Now passes all the %G and %V test cases on Windows, Linux and Solaris [Bugs #500285, #500389, and #852944] 2004-05-18 Donal K. Fellows * doc/append.n, doc/upvar.n: Added example. 2004-05-18 David Gravereaux * win/makefile.vc: now generates a tclConfig.sh from Pat Thoyts [Patch 909911] 2004-05-18 Donal K. Fellows * doc/lsearch.n: Improve clarity (based on [Patch 955361] by Peter Spjuth) * tools/man2help2.tcl (macro,SHmacro): Added support for subsection (.SS) header macros. * doc/interp.n: Added user documentation for the TIP#143 resource limits and some examples. * generic/tclInterp.c (Tcl_LimitCheck, Tcl_LimitTypeReset): Reset the limit-exceeded flag when removing a limit. 2004-05-18 Miguel Sofer * generic/tclExecute.c (TclExecuteByteCode): added comments to classify the variables according to their use in TEBC. 2004-05-17 Donal K. Fellows * doc/global.n, doc/uplevel.n: Added an example. * tests/info.test (info-3.1): Corrected test result back to what it used to be in Tcl 7.* now that command counts are being correctly kept. * generic/tclExecute.c (TEBC:INST_START_CMD): Make sure that the command-count is always advanced. Allows TIP#143 limits to tell that work is being done. * doc/list.n: Updated example to fit with the unified format. * doc/seek.n: Added some examples. 2004-05-17 Vince Darley * win/tclWinFile.c: * tests/cmdAH.test: fix to (Bug 954263) where 'file executable' was case-sensitive. 2004-05-17 Donal K. Fellows * doc/OpenFileChnl.3: Documented type of 'offset' argument to Tcl_Seek was wrong. [Bug 953374] 2004-05-16 Miguel Sofer * generic/tclExecute.c (TclExecuteByteCode): remove one level of indirection for compiledLocals addressing. 2004-05-16 Miguel Sofer * generic/tclExecute.c (INST_CALL_FUNC1): bugfix; restored (DE)CACHE_STACK_INFO pair around the call - the user defined math function could cause a recursive call to TEBC. 2004-05-16 Miguel Sofer * generic/tclBasic.c (Tcl_DeleteInterp): * generic/tclExecute.c (INST_START_CMD): interp deletion now modifies the compileEpoch, eliminating the need for the check for interp deletion in INST_START_CMD. 2004-05-16 Miguel Sofer * generic/tclCompile.h: * generic/tclCompile.c: * generic/tclExecute.c: changed implementation of {expand}, last chance while in alpha as ... ***POTENTIAL INCOMPATIBILITY*** Scripts precompiled with ProComp under previous tcl8.5a versions may malfunction due to changed instruction numbers for INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD. 2004-05-14 Kevin B. Kenny * generic/tclInt.decls: Promoted TclpLocaltime and TclpGmtime * generic/tclIntDecls.h: from Unix-specific stubs to the generic * generic/tclIntPlatDecls.h: internal Stubs table. Reran 'genstubs' * generic/tclStubInit.c: * unix/tclUnixPort.h: * generic/tclClock.c: Changed a buggy 'GMT' timezone specification to the correct 'GMT0'. [Bug #922848] * unix/tclUnixThrd.c: Moved TclpGmtime and TclpLocaltime to unix/tclUnixTime.c where they belong. * unix/tclUnixTime.c (TclpGmtime, TclpLocaltime, TclpGetTimeZone, ThreadSafeGMTime [removed], ThreadSafeLocalTime [removed], SetTZIfNecessary, CleanupMemory): Restructured to make sure that the same mutex protects all calls to localtime, gmtime, and tzset. Added a check in front of those calls to make sure that the TZ env var hasn't changed since the last call to tzset, and repeat tzset if necessary. [Bug #942078] Removed a buggy test of the Daylight Saving Time information in 'gettimeofday' in favor of applying 'localtime' to a known value. [Bug #922848] * tests/clock.test (clock-3.14): Added test to make sure that changes to $env(TZ) take effect immediately. * win/tclWinTime.c (TclpLocaltime, TclpGmtime): Added porting layer for 'localtime' and 'gmtime' calls. 2004-05-14 Miguel Sofer * generic/tclExecute.c: * generic/tclCompile.h: the math functions receive a pointer to top of the stack (tosPtr) instead of the execution environment (eePtr). First step towards a change in the execution stack management - it is now only used within TEBC. 2004-05-13 Donal K. Fellows TIP#143 IMPLEMENTATION * generic/tclExecute.c (TclCompEvalObj, TclExecuteByteCode): * generic/tclBasic.c (TclEvalObjvInternal): Enable limit checking. * generic/tclInterp.c (Tcl_Limit*): Public limit API. * generic/tcl.decls: * tests/interp.test: Basic tests of command limits. * doc/binary.n: TIP#129 IMPLEMENTATION [Patch 858211] * generic/tclBinary.c: Note that the test suite probably has many more * tests/binary.test: failures now due to alterations in constraints. 2004-05-12 Miguel Sofer Optimisations for INST_START_CMD [Bug 926164]. * generic/tclCompile.c (TclCompileScript): avoid emitting INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It is not needed, as the checks are done before calling TEBC. * generic/tclExecute.c (TclExecuteByteCode): runtime peephole optimisation: check at INST_POP if the next instruction is INST_START_CMD, in which case we fall through. 2004-05-11 Donal K. Fellows * doc/split.n, doc/join.n: Updated examples and added more. 2004-05-11 Vince Darley * doc/glob.n: documented behaviour of symbolic links with 'glob -types d' (Bug 951489) 2004-05-11 Donal K. Fellows * doc/scan.n: Updated the examples to be clearer about their relevance to the scan command. 2004-05-10 Donal K. Fellows * doc/scan.n: Added examples. 2004-05-10 David Gravereaux * win/tclWinPipe.c (BuildCommandLine): Moved non-obvious appending logic to outside the loop and added commentary for its purpose. Also use the existence of contents in the linePtr rather than the scratch DString post the append, as this more clear. (TclpCreateProcess): When under NT, with no console, and executing a DOS application, the path priming does not need an ending space as BuildCommandLine() will do this for us. 2004-05-08 Vince Darley * generic/tclFileName.c: * generic/tclIOUtil.c: remove some compiler warnings on MacOS X. 2004-05-07 Chengye Mao * win/tclWinPipe.c: refixed bug 789040 re-entered in rev 1.41. Let's be careful and don't re-enter previously fixed bugs. 2004-05-08 Donal K. Fellows * doc/format.n: Added examples. 2004-05-07 Miguel Sofer * doc/unset.n: added upvar.n to the "see also" list 2004-05-07 Reinhard Max * generic/tclEncoding.c: * tests/encoding.test: added support and tests for translating embedded null characters between real nullbytes and the internal representation on input/output (Bug #949905). 2004-05-07 Vince Darley * generic/tclFileName.c: * generic/tclIOUtil.c: * generic/tclFileSystem.h: * tests/fileSystem.test: fix for [Bug 943995], in which vfs- registered root volumes were not handled correctly as glob patterns in all circumstances. 2004-05-06 Miguel Sofer * generic/tclInt.h: * generic/tclObj.c (TclFreeObj): made TclFreeObj use the new macro TclFreeObjMacro(), so that the allocation and freeing of Tcl_Obj is defined in a single spot (the macros in tclInt.h), with the exception of the TCL_MEM_DEBUG case. The #ifdef logic for the corresponding macros has been reformulated to make it clearer. 2004-05-05 Donal K. Fellows * doc/break.n, doc/continue.n, doc/for.n, doc/while.n: More examples. 2004-05-05 Don Porter * tests/unixInit.test (unixInit-2.10): Test correction for Mac OSX. Be sure to consistently compare normalized path names. Thanks to Steven Abner (tauvan). [Bug 948177] 2004-05-05 Donal K. Fellows * doc/CrtObjCmd.3: Remove reference to Tcl_RenameCommand; there is no such API. [Bug 848440] 2004-05-05 David Gravereaux * win/tclWinSock.c (SocketEventProc) : connect errors should fire both the readable and writable handlers because this is how it works on UNIX [Bug 794839] * generic/tclEncoding.c (TclFinalizeEncodingSubsystem): FreeEncoding(systemEncoding); moved to before the hash table itereation as it was causing a double free attempt under some conditions. * win/coffbase.txt: Added the tls extension to the list of preferred load addresses. 2004-05-04 Jeff Hobbs * tests/fileSystem.test (filesystem-1.39): replace 'file volumes' * tests/fileName.test (filename-12.9,10): lindex with direct C:/ hard-coded because A:/ was being used and that is empty for most. * tests/winFCmd.test (winFCmd-16.12): test volumerelative $HOME 2004-05-04 Don Porter * generic/tclAlloc.c: Make sure Tclp*Alloc* routines get * generic/tclInt.h: declared in the TCL_MEM_DEBUG and * generic/tclThreadAlloc.c: TCL_THREADS configuration.

Todd Helfter reported that the macro is required by tbcload. 2004-05-03 Kevin Kenny * win/tclWin32Dll.c (TclpCheckStackSpace): * tests/stack.test (stack-3.1): Fix for undetected stack overflow in TclReExec on Windows. [Bug 947070] 2004-05-03 Don Porter * library/init.tcl: Corrected unique prefix matching of interactive command completion in [unknown]. [Bug 946952] 2004-05-02 Miguel Sofer * generic/tclProc.c (TclObjInvokeProc): * tests/proc.test (proc-3.6): fix for bad quoting of multi-word proc names in error messages [Bug 942757] 2004-04-30 Donal K.

Kenny * generic/tclThreadAlloc.c: Added a temporary (or so I hope!) inclusion of "tclWinInt.h" to avoid problems when compiling on Win32-VC++ with --enable-threads. [Bug 945447] 2004-04-30 Donal K. Fellows * doc/puts.n: Added a few examples. 2004-04-29 Don Porter * tests/execute.test (execute-8.2): Avoid crashes when there is limited system stack space (threads-enabled). 2004-04-28 Miguel Sofer * doc/global.n: * doc/upvar.n: * generic/tclVar.c (ObjMakeUpvar): * tests/upvar.test (upvar-8.11): * tests/var.test (var-3.11): Avoid creation of unusable variables: [Bug 600812] [TIP 184]. 2004-04-28 Donal K.

[Bug 941108] 2004-04-26 Donal K. Fellows * doc/open.n, doc/close.n: Updated (thanks to David Welton) to be clearer about pipeline errors and added example to open(n) that shows simple pipeline use. [Patches 941377,941380] * doc/DictObj.3: Added warning about the use of Tcl_DictObjDone and an example of use of iteration. [Bug 940843] * doc/Thread.3: Reworked to remove references to testing interfaces and instead promote the use of the Thread package. [Patch 932527] Also reworked and reordered the page for better readability. 2004-04-25 Don Porter * generic/tcl.h: Removed obsolete declarations and #include's. * generic/tclInt.h: [Bugs 926459, 926486] 2004-04-24 David Gravereaux * win/tclWin32Dll.c (DllMain): Added DisableThreadLibraryCalls() for the DLL_PROCESS_ATTACH case. We're not interested in knowing about DLL_THREAD_ATTACH, so disable the notices. 2004-04-24 Daniel Steffen * generic/tclPort.h: * macosx/Makefile: * unix/Makefile.in: followup on tcl header reform [FR 922727]: removed use of relative #include paths in tclPort.h to allow installation of private headers outside of tcl source tree; added 'unix' dir to compiler header search path; add newly required tcl private headers to Tcl.framework on Mac OSX. 2004-04-23 Andreas Kupries * generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bug 930851]. When changing the eofchar we have to zap the related flags to prevent them from prematurely aborting the next read. 2004-04-25 Vince Darley * generic/tclPathObj.c: fix to [Bug 940281]. Tcl_FSJoinPath will now always return a valid Tcl_Obj when the input is valid. * generic/tclIOUtil.c: fix to [Bug 931823] for a more consistent Tcl_FSPathSeparator() implementation which allows filesystems not to implement their Tcl_FSFilesystemSeparatorProc if they wish to use the default '/'. Also fixed associated memory leak seen with, e.g., tclvfs package. * doc/FileSystem.3: documented Tcl_FSJoinPath return values more clearly, and Tcl_FSFilesystemSeparatorProc requirements. 2004-04-23 David Gravereaux * win/tclWin32Dll.c: Removed my mistake from 4/19 of adding an exit handler to TclWinInit. TclWinEncodingsCleanup called from TclFinalizeFilesystem does the Tcl_FreeEncoding for us. * win/tclWinChan.c (Tcl_MakeFileChannel) : Case for CloseHandle returning zero and not throwing a RaiseException(EXCEPTION_INVALID_HANDLE) now being done. 2004-04-22 David Gravereaux * generic/tclEvent.c: TclSetLibraryPath's use of caching the stringrep of the pathPtr object to TclGetLibraryPath called from another thread was ineffective if the original's stringrep had been invalidated as what happens when it gets muted to a list. * win/tclWinTime.c: If the Tcl_ExitProc (StopCalibration) is called from the stack frame of DllMain's PROCESS_DETACH, the wait operation should timeout and continue. * generic/tclInt.h: * generic/tclThread.c: * generic/tclEvent.c: * unix/tclUnixThrd.c: * win/tclWinThrd.c: Provisions made so masterLock, initLock, allocLock and joinLock mutexes can be recovered during Tcl_Finalize. 2004-04-22 Donal K. Fellows * doc/switch.n: Reworked the examples to be more systematically named and to cover some TIP#75 capabilities. * doc/cd.n: Documentation clarification from David Welton. * doc/exec.n: Added some examples, Windows ones from Arjen Markus and Unix ones by myself. 2004-04-21 Donal K. Fellows * doc/Hash.3: Added note to Tcl_{First,Next}HashEntry docs that deleting the element they return is supported (and is in fact the only safe update you can do to the structure of a hashtable while an iteration is going over it.) * doc/bgerror.n: Added example from David Welton. [Patch 939473] * doc/after.n: Added examples from David Welton. [Patch 938820] 2004-04-19 David Gravereaux * win/tclWin32Dll.c: Added an exit handler in TclWinInit() so tclWinTCharEncoding could be freed during Tcl_Finalize(). * generic/tclEncoding.c: Added FreeEncoding(systemEncoding) in TclFinalizeEncodingSubsystem because its ref count was incremented in TclInitEncodingSubsystem. 2004-04-19 Donal K. Fellows * doc/read.n: Added example from David Welton. [Patch 938056] 2004-04-19 Kevin B. Kenny * generic/tclObj.c (Tcl_GetDoubleFromObj) Corrected "short circuit" conversion of int to double.

Fellows * generic/tclClock.c (Tcl_ClockObjCmd): Minor fault in a [clock clicks] error message. 2004-04-07 Jeff Hobbs * win/tclWinInit.c (TclpSetInitialEncodings): note that WIN32_CE is also a unicode platform. * generic/tclEncoding.c (TclFindEncodings, Tcl_FindExecutable): * generic/tclInt.h: Correct handling of UTF * unix/tclUnixInit.c (TclpInitLibraryPath): data that is actually * win/tclWinFile.c (TclpFindExecutable): "clean", allowing the * win/tclWinInit.c (TclpInitLibraryPath): loading of Tcl from paths that contain multi-byte chars on Windows [Bug 920667] * win/configure: define TCL_LIB_FLAG, TCL_BUILD_LIB_SPEC, * win/configure.in: TCL_LIB_SPEC, TCL_PACKAGE_PATH in tclConfig.sh. 2004-04-06 Don Porter 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 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): End Patch 922727. * tests/unixInit.test (unixInit-3.1): Default encoding on Darwin systems is utf-8. Thanks to Steven Abner (tauvan). [Bug 928808] 2004-04-06 Donal K. Fellows * tests/cmdAH.test (cmdAH-18.2): Added constraint because access(...,X_OK) is defined to be permitted to be meaningless when running as root, and OSX exhibits this. [Bug 929892] 2004-04-02 Miguel Sofer * generic/tclCompile.c: * generic/tclInt.h: removed the macro TCL_ALIGN() from tclInt.h, replaced by the static macro ALIGN() in tclCompile.c [Bug 926445] 2004-04-02 Miguel Sofer * generic/tclCompile.h: removed redundant #ifdef _TCLINT [Bug 928415], reported by tauvan. 2004-04-02 Don Porter * tests/tcltest.test: Corrected constraint typos: "nonRoot" -> "notRoot". Thanks to Steven Abner (tauvan). [Bug 928353] 2004-04-01 Don Porter * generic/tclInt.h: Removed obsolete tclBlockTime* declarations. [Bug 926454] 2004-04-01 Vince Darley * generic/tclIOUtil.c: Fix to privately reported vfs bug with 'glob -type d -dir . *' across a vfs boundary. No tests for this are currently possible without effectively moving tclvfs into Tcl's test suite. 2004-03-31 Don Porter * doc/msgcat.n: Clarified message catalog file encodings. [Bug 811457] * library/msgcat/msgcat.tcl: Updated internals to make use of [dict]s to store message catalog data and to use [source -encoding utf-8] to access catalog files. Thanks to Michael Sclenker. [Patch 875055, RFE 811459] Corrected [mcset] to be able to successfully set a translation to the empty string. [mcset $loc $src {}] was incorrectly set the $loc translation of $src back to $src. Also changed [ConvertLocale] to minimally require a non-empty "language" part in the locale value. If not, an error raised prompts [Init] to keep looking for a valid locale value, or ultimately fall back on the "C" locale. [Bug 811461]. * library/msgcat/pkgIndex.tcl: Bump to msgcat 1.4.1. 2004-03-30 Donal K. Fellows * generic/tclHash.c (HashStringKey): Cleaned up. This function is not faster, but it is a little bit clearer. * generic/tclLiteral.c (HashString): Applied logic from HashObjKey. * generic/tclObj.c (HashObjKey): Rewrote to fix fault which hashed every single-character object to the same hash bucket. The new code is shorter, simpler, clearer, and (happily) faster. 2004-03-30 Miguel Sofer * generic/tclExecute.c (TEBC): reverting to the previous method for async tests in TEBC, as the new method turned out to be too costly. Async tests now run every 64 instructions. 2004-03-30 Miguel Sofer * generic/tclCompile.c: New instruction code INST_START_CMD * generic/tclCompile.h: that allows checking the bytecode's * generic/tclExecute.c: validity [Bug 729692] and the interp's * tests/interp.test (18.9): readyness [Bug 495830] before running * tests/proc.test (7.1): the command. It also changes the * tests/rename.test (6.1): mechanics of the async tests in TEBC, doing it now at command start instead of every 16 instructions. 2004-03-30 Vince Darley * generic/tclFileName.c: Fix to Windows glob where the pattern is * generic/tclIOUtil.c: a volume relative path or a network * tests/fileName.test: share [Bug 898238]. On windows 'glob' * tests/fileSystem.test: will now return the results of 'glob /foo/bar' and 'glob \\foo\\bar' as 'C:/foo/bar', i.e. a correct absolute path (rather than a volume relative path). Note that the test suite does not test commands like 'glob //Machine/Shared/*' (on a network share). 2004-03-30 Vince Darley * generic/tclPathObj.c: Fix to filename bugs recently * tests/fileName.test: introduced [Bug 918320]. 2004-03-29 Don Porter * generic/tclMain.c (Tcl_Main, StdinProc): Append newline only * tests/basic.test (basic-46.1): to incomplete scripts as part of multi-line script construction. Do not add an extra trailing newline to the complete script. [Bug 833150] 2004-03-28 Miguel Sofer * generic/tclCompile.c (TclCompileScript): corrected possible segfault when a compilation returns TCL_OUTLINE_COMPILE after having grown the compile environment [Bug 925121]. 2004-03-27 Miguel Sofer * doc/array.n: added documentation for trace-realted behaviour of 'array get' [Bug 449893] 2004-03-26 Don Porter * README: Bumped version number to 8.5a2 to * tools/tcl.wse.in: distinguish HEAD of CVS development * unix/configure.in: from the recent 8.5a1 release. * unix/tcl.spec: * win/README.binary: * win/configure.in: * unix/configure: autoconf-2.57 * win/configure: 2004-03-26 Vince Darley * generic/tclPathObj.c: Fix to Windows-only volume relative * tests/fileSystem.test: path normalization. [Bug 923568]. Also fixed another volume relative bug found while testing. 2004-03-24 Donal K. Fellows * generic/tclNamesp.c (NsEnsembleImplementationCmd): Fix messed up handling of strncmp result which just happened to work in some libc implementations. [Bug 922752] 2004-03-23 Donal K. Fellows * doc/StringObj.3: Inverted the sense of the documentation of how the bytes parameter is documented to match behaviour. [Bug 921464] 2004-03-19 Kevin B.

That worked when lib was "lib/..." but fails for other values. Thanks go to Patrick Samson for pointing this out. 2004-02-10 David Gravereaux * win/nmakehlp.c: better macro grepping logic. 2004-02-07 David Gravereaux * win/makefile.vc: * win/rules.vc: * win/tcl.rc: * win/tclsh.rc: Added an 'unchecked' option to the OPTS macro so a core built with symbols can be linked to the non-debug enabled C run-time. As per discussion with Kevin Kenny. Called like this: nmake -af makefile.vc OPTS=unchecked,symbols This clarifies the meaning of the 'g' naming suffix to mean only that the binary requires the debug enabled C run-time. Whether the binary contains symbols or not is a different condition. 2004-02-06 Don Porter * doc/clock.n: Removed reference to non-existent [file ctime]. 2004-02-05 David Gravereaux * docs/tclvars.n: Added clarification of the tcl_platform(debug) var that it only refers to the flavor of the C run-time, and not whether the core contains symbols. 2004-02-05 Don Porter * generic/tclFileName.c (SkipToChar): Corrected CONST and type-casting issues that caused compiler warnings. 2004-02-04 Don Porter * generic/tclCmdAH.c (StoreStatData): Removed improper refcount decrement of the varName parameter.

[Bug 885537] -------- * tests/winPipe.test: Added proof that BuildCommandLine() is not doing the "N backslashes followed a quote -> insert N * 2 + 1 backslashes then a quote" rule needed for the crt's parse_cmdline(). * win/tclWinPipe.c: Fixed BuildCommandLine() to pass the new cases. 2004-01-30 David Gravereaux * win/makefile.vc: Use the -GZ compiler switch when building for symbols. This is supposed to emulate the release build better to avoid hiding problems that only show themselves in a release build. 2004-01-29 Vince Darley * generic/tclPathObj.c: fix to [Bug 883143] in file normalization 2004-01-29 Vince Darley * doc/file.n: * generic/tclFCmd.c * generic/tclTest.c * library/init.tcl * mac/tclMacFile.c * tests/fileSystem.test: fix to [Bug 886352] where 'file copy -force' had inconsistent behaviour wrt target files with insufficient permissions, particular from vfs->native fs. Behaviour of '-force' is now always consistent (and now consistent with behaviour of 'file delete -force'). Added new tests and documentation and cleaned up the 'simplefs' test filesystem. * generic/tclIOUtil.c * unix/tclUnixFCmd.c * unix/tclUnixFile.c * win/tclWinFile.c: made native filesystems more robust to C code which asks for mount lists. * generic/tclPathObj.c: fix to [Bug 886607] removing warning/error with some compilers. 2004-01-28 Donal K. Fellows * generic/tclObj.c (SetBooleanFromAny): Rewrite to do more efficient string->bool conversion. Many other minor whitespace/style fixes to this file too. 2004-01-27 David Gravereaux * win/nmakehlp.c: Use '.\nul' as the sourcefile name instead of 'nul' so VC 5.2 doesn't try searching the path for it and failing with a possible dialogbox popping up about having to add a CD to an empty drive. Also added a SetErrorMode() call to disable any dialogs that cl.exe or link.exe might create. [Bug 885537] 2004-01-22 Vince Darley * doc/file.n: clarified documentation of 'file system' [Bug 883825] * tests/fCmd.test: improved test result in failure case. 2004-01-22 Vince Darley * tests/fileSystem.test: 3 new tests * generic/tclPathObj.c: fix to [Bug 879555] in file normalization. * doc/filename.n: small clarification to Windows behaviour with filenames like '.....', 'a.....', '.....a'. * generic/tclIOUtil.c: slight improvement to native cwd caching on Windows. 2004-01-21 David Gravereaux * doc/Panic.3: Mentions of 'panic' and 'panicVA' removed from the documentation. 2004-01-21 Vince Darley * doc/FileSystem.3: * generic/tcl.decls: * generic/tclCmdAH.c * generic/tclDecls.h * generic/tclFCmd.c * generic/tclFileName.c * generic/tclFileSystem.h * generic/tclIOUtil.c * generic/tclInt.decls * generic/tclInt.h * generic/tclIntDecls.h * generic/tclPathObj.c * generic/tclStubInit.c * generic/tclTest.c * mac/tclMacFile.c * tests/fileName.test * tests/fileSystem.test * tests/winFCmd.test * unix/tclUnixFile.c * win/tclWin32Dll.c * win/tclWinFCmd.c * win/tclWinFile.c * win/tclWinInt.h Three main issues accomplished: (1) cleaned up variable names in the filesystem code so that 'pathPtr' is used throughout. (2) applied a round of filesystem optimisation with better handling and caching of relative and absolute paths, requiring fewer conversions. (3) clarifications to the documentation, particularly regarding the acceptable refCounts of objects. Some new tests added. Tcl benchmarks show a significant improvement over 8.4.5, and on Windows typically a small improvement over 8.3.5 (Unix still appears to require optimisation). TCL_FILESYSTEM_VERSION_2 introduced, but for internal use only. There should be no public incompatibilities from these changes. Thanks to dgp for extensive testing. 2004-01-19 David Gravereaux * win/tclWinPipe.c (Tcl_WaitPid): Fixed a thread-safety problem with the process list. The delayed cut operation after the wait was going stale by being outside the list lock. It now cuts within the lock and does a locked splice for when it needs to instead. [Bug 859820] 2004-01-18 Donal K. Fellows * generic/tclCompile.c, generic/tclCompile.h: Two new opcodes, INST_LIST_INDEX_IMM and INST_LIST_RANGE_IMM, that have operand(s) of new type OPERAND_IDX4 which represents indexes into things like lists (and perhaps other things eventually.) * generic/tclExecute.c (TclExecuteByteCode): Implementation of the new opcodes. INST_LIST_INDEX_IMM does a simple [lindex] with either front- or end-based simple indexing. INST_LIST_RANGE_IMM does an [lrange] with front- or end-based simple indexing for both the reference to the first and last items in the range. * generic/tclCompCmds.c (TclCompileLassignCmd): Generate bytecode for the [lassign] command. 2004-01-17 David Gravereaux * win/tclWinInit.c: added #pragma comment(lib, "advapi32.lib") when compiling under VC++ so we don't need to specify it when linking. 2004-01-17 Donal K. Fellows * generic/tclCmdIL.c (Tcl_LassignObjCmd): Add more shimmering protection for when the list is also one of the variables. BASIC IMPLEMENTATION OF TIP#57 * generic/tclCmdIL.c (Tcl_LassignObjCmd): Implementation of the [lassign] command that takes full advantage of Tcl's object API. * doc/lassign.n: New file documenting the command. * tests/cmdIL.test (cmdIL-6.*): Test suite for the command. 2004-01-15 David Gravereaux * win/tclWinReg.c: Placed the requirement for advapi.lib into the object file itself with #paragma comment (lib, ...) when built with VC++. This will simplify linking for users of the static library. * win/rules.vc: Added new 'fullwarn' to the CHECKS commandline macro; sets $(FULLWARNINGS). * win/makefile.vc: Removed 'advapi.lib' from $(baselibs). Added new logic to crank-up the warning levels for both compile and link when $(FULLWARNINGS) is set. Some clean-up with how the resource files are built and how -DTCL_USE_STATIC_PACKAGES is sent when compiling the shells. * win/tclAppInit.c: Small change in how TCL_USE_STATIC_PACKAGES is used. * win/tcl.rc: * win/tclsh.rc: Some clean-up with how the resource files are built. Fixed 'OriginalFilename' problem that still thought a debug suffix was still 'd', now is 'g'. 2004-01-14 Donal K. Fellows * generic/tclDictObj.c (TraceDictPath, DictExistsCmd): Adjusted behaviour of [dict exists] so a failure to look up a dictionary along the path of dicts doesn't trigger an error. This is how it was documented to behave previously... [Bug 871387] * generic/tclDictObj.c: Assorted dict fixes from Peter Spjuth relating to [Bug 876170]. (SetDictFromAny): Make sure that lists retain their ordering even when converted to dictionaries and back. (TraceDictPath): Correct object reference count handling! (DictReplaceCmd, DictRemoveCmd): Stop object leak. (DictIncrCmd,DictLappendCmd,DictAppendCmd,DictSetCmd,DictUnsetCmd): Simpler handling of reference counts when assigning to variables. * tests/dict.test (dict-19.2): Memory leak stress test 2004-01-13 Don Porter * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): Silence compiler warnings. Patch 876451: restores performance of [return]. Also allows forms such as [return -code error $msg] to be bytecompiled. * generic/tclInt.h: Factored Tcl_ReturnObjCmd() into two pieces: * generic/tclCmdMZ.c: TclMergeReturnOptions(), which can parse the options to [return], check their validity, and create the corresponding return options dictionary, and TclProcessReturn(), which takes that return options dictionary and performs the [return] operation. * generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to call TclMergeReturnOptions() at compile time so the return options dictionary is computed at compile time (when it is fully known). The dictionary is pushed on the stack along with the result, and the code and level values are included in the bytecode as operands. Also supports optimized compilation of un-[catch]ed [return]s from procs with default options into the INST_DONE instruction. * generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve the code and level operands, pop the return options from the stack, and call TclProcessReturn() to perform the [return] operation. * generic/tclCompile.h: New utilities include TclEmitInt4 macro * generic/tclCompile.c: and TclWordKnownAtCompileTime(). End Patch 876451. * generic/tclFileName.c (Tcl_GlobObjCmd): Latest changes to management of the interp result by Tcl_GetIndexFromObj() exposed improper interp result management in the [glob] command procedure. Corrected by adopting the Tcl_SetObjResult(Tcl_NewStringObj) pattern. This stopped a segfault in test filename-11.36. [Bug 877677] 2004-01-13 Donal K. Fellows * generic/tclIndexObj.c (Tcl_GetIndexFromObjStruct, Tcl_WrongNumArgs): Create fresh objects instead of using the one currently in the interpreter, which isn't guaranteed to be fresh and unshared. The cost for the core will be minimal because of the object cache, and this fixes [Bug 875395]. 2004-01-12 Miguel Sofer * generic/tclCompExpr.c (CompileLandOrLorExpr): cosmetic changes. 2004-01-12 Miguel Sofer * generic/tclCompExpr.c (CompileLandOrLorExpr): new logic, fewer instructions. As a side effect, the instructions INST_LOR and INST_LAND are now never used. * generic/tclExecute.c (INST_JUMP*): small optimisation; fix a bug in debug code. 2004-01-11 David Gravereaux * win/tclWinThrd.c (Tcl_ConditionNotify): condPtr must be dereferenced to see if there are waiters else uninitialized datum is manipulated. [Bug 849007 789338 745068] 2004-01-09 David Gravereaux * generic/tcl.h: Renamed and deprecated #defines moved to within the #ifndef TCL_NO_DEPRECATED block. This allows us to build Tcl to check for deprecated functions in use, such as panic() and Tcl_Ckalloc(). By request from DKF. Extensions that build with -DTCL_NO_DEPRECATED now have these macros as restricted. ***POTENTIAL INCOMPATIBILITY*** * win/makefile.vc: * win/rules.vc: Added -DTCL_NO_DEPRECATED usage to makefile.vc.
