Added code to initialize and manage the script + cancellation hash table in a thread-safe manner. Reset script + cancellation flags prior to increasing the nesting level (if the nesting + level is currently zero) and always cooperatively check for script + cancellation near the start of TclEvalObjvInternal and after invoking + async handlers. + * generic/tclDecls.h: Regenerated. + * generic/tclEvent.c: Call TclFinalizeEvaluation during finalization to + cleanup the script cancellation hash table. During [vwait], always + cooperatively check for script cancellation. Corrected the spelling of + 'canceled' in comments to be consistent with the documentation. + * generic/tclExecute.c: Reset script cancellation flags prior to + increasing the nesting level (if the nesting level is currently zero) and + always cooperatively check for script cancellation after invoking async + handlers. Prevent [catch] from catching script cancellation when the + TCL_CANCEL_UNWIND flag is set (similar to the manner used by TIP 143 when + a limit has been exceeded). + * generic/tclInt.decls: Added TclResetCancellation to the internal stubs + table. + * generic/tclInt.h: Added asyncCancel and asyncCancelMsg fields to the + private Interp structure. Added private interp flag value CANCELED to + help control script cancellation. + * generic/tclIntDecls.h: Regenerated. + * generic/tclInterp.c (Tcl_InterpObjCmd): Added [interp cancel] + subcommand. + * generic/tclNotify.c (Tcl_DeleteEventSource): Corrected the spelling of + 'canceled' in comments to be consistent with the documentation. + * generic/tclParse.c: Reset script cancellation flags prior to increasing + * generic/tclProc.c: the nesting level (if the nesting level is currently + zero) and cooperatively check for script cancellation prior to evaluating + commands. + * generic/tclStubInit.c: Regenerated. + * generic/tclThreadTest.c (Tcl_ThreadObjCmd): Added script cancellation + support ([testthread cancel]). + Modified [testthread id] to allow querying of the 'main' thread ID. + Corrected comments to reflect the actual command syntax. Made [testthread + wait] cooperatively check for script cancellation. Added [testthread + event] to allow for processing one pending event without blocking. + * generic/tclTimer.c: Delay for a maximum of 500 milliseconds prior + to checking for async handlers and script cancellation. + * tests/cmdAH.test: Changed [interp c] to [interp create]. + * tests/interp.test: Added and fixed tests for [interp cancel]. + * tests/thread.test: Added tests for script cancellation via [testthread + cancel]. + * tools/man2help2.tcl: Fixed problems with WinHelp target (see + * tools/man2tcl.c: [Bug 1934200], [Bug 1934265], and [Bug 1934272]). + * win/makefile.vc: Added 'pdbs' option for Windows build rules to allow + * win/rules.vc: for non-debug builds with full symbols. + * win/tcl.hpj.in: Corrected version for WinHelp target. + * win/tclWinNotify.c: Used SleepEx and WaitForSingleObjectEx on + * win/tclWinThrd.c: Windows because they are alertable. + 2008-06-12 Daniel Steffen <das@users.sourceforge.net> * unix/Makefile.in: add complete deps on tclDTrace.h. |
