| | | | | | * tests/io.test: which used the number of _written_ bytes or character to update the counters for the read bytes/characters. New test io-53.11. This is a backward port from the 8.5 branch.

| | | | | | | refCount for the file path out of the branch after the whole conditional, closing a memory leak. Added clause on structure type to prevent seg.faulting. Backport from valgrinding the Tcl 8.5 branch.

| | | | | | TclCompileLindexCmd): Fixed. Moved the use of DefineLineInformation after all regular variable declarations, so that an empty statement (-UTIP_280) doesn't confuse c89 compilers.

The code here is much simpler (trimmed down) compared to the head as the 8.4 branch is not bytecode compiling whole files, and doesn't compile eval'd code either. 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 removes the problems with location data caused by literal sharing in proc bodies. Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex).
* * generic/tclCompile.c: The value stashed in iPtr->compiledProcPtrdgp2009-06-132-7/+3
| | | | | | | | | | | | | * 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].
