| | | | | | * 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/tclInt.decls: New internal routine TclBackgroundException()dgp2007-09-068-41/+118
| | | | | | | | | | | | | | | | * 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:

| | | | | | | | | | | | | | | | expression syntax errors are found when compiling expressions. With this in place, convert TclCompileExpr to return void, since there's no longer any need to report TCL_ERROR. * generic/tclCompile.c: Update callers. * generic/tclExecute.c: * generic/tclCompCmds.c: New routine TclCompileSyntaxError() * generic/tclCompile.h: to directly compile bytecodes that report a * generic/tclCompile.c: syntax error, rather than (ab)use a call to TclCompileReturnCmd. Also, undo the most recent commit that papered over some issues with that (ab)use. New routine produces a new opcode INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit of constification.
