| | | | | | | | | | * generic/tclParse.c: wrapper around TclNRSubstObj(). This has * tests/basic.test: the effect of caching compiled bytecode in * tests/parse.test: the value to be substituted. Note that Tcl_SubstObj() now exists only for extensions. Tcl itself no longer makes any use of it. Note also that TclSubstTokens() is now reachable only by Tcl_EvalEx() and Tcl_ParseVar() so tests aiming to test its functioning needed adjustment to still have the intended effect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TclCleanupByteCode, TclCompileScript): * generic/tclExecute.c (TclCompileObj, TclExecuteByteCode): * tclCompile.h (ExtCmdLoc): * tclInt.h (ExtIndex, CFWordBC, CmdFrame): * tclBasic.c (DeleteInterpProc, TclArgumentBCEnter, TclArgumentBCRelease, TclArgumentGet, SAVE_CONTEXT, RESTORE_CONTEXT, NRCoroutineExitCallback, TclNRCoroutineObjCmd): * generic/tclCmdAH.c (TclNRForObjCmd, TclNRForIterCallback, ForNextCallback): * generic/tclCmdMZ.c (TclNRWhileObjCmd): Extended the bytecode compiler initialization to recognize the compilation of whole files (NRE enabled 'source' command) and switch to the counting of absolute lines in that case. Further extended the bytecode compiler to track the start line in the generated information, and modified the bytecode execution to recompile an object if the location as per the calling context doesn't match the location saved in the bytecode. This part could be optimized more by using more memory to keep all possibilities which occur around, or by just adjusting the location information instead of a total recompile. Reworked the handling of literal command arguments in bytecode to be saved (compiler) and used (execution) per command (See the TCL_INVOKE_STK* instructions), and not per the whole bytecode. This, and the previous change remove the problems with location data caused by literal sharing (across whole files, but also proc bodies). Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex). The last change causes the hashtable 'lineLABCPtr' to be state which has to be kept per coroutine, like the CmdFrame stack. Reworked the coroutine support code to create, delete and switch the information as needed. Further reworked the tailcall command as well, it has to pop its own arguments when run in a bytecode context to keep a proper stack in 'lineLABCPtr'. Fixed the mishandling of line information in the NRE-enabled 'for' and 'while' commands introduced when both were made to share their iteration callbacks without taking into account that the loop body is found in different words of the command. Introduced a separate data structure to hold all the callback information, as we went over the limit of 4 direct client-data values for NRE callbacks. The above fixes [Bug 1605269].
* * generic/tclCompile.c: The value stashed in iPtr->compiledProcPtrdgp2009-06-131-1/+2
| | | | | | | | | | | | | * generic/tclProc.c: when compiling a proc survives too long. We * tests/execute.test: only need it there long enough for the right TclInitCompileEnv() call to re-stash it into envPtr->procPtr. Once that is done, the CompileEnv controls. If we let the value of iPtr->compiledProcPtr linger, though, then any other bytecode compile operation that takes place will also have its CompileEnv initialized with it, and that's not correct. The value is meant to control the compile of the proc body only, not other compile tasks that happen along. Thanks to Carlos Tasada for discovering and reporting the problem. [Bug 2802881].
