* * generic/tclProc.c (TclCloneProc): Fixed leaking of 'procNew', mod_8_3_4_branchandreas_kupries2003-05-072-1/+7

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | error messages generated when cloning fails from the clone to the master, for perusal by the code which activated the cloning process. This is especially important to track syntax errors in procedures to clone down. The code was provided by Greg Thompson <gst@cisco.com>. * generic/tclBasic.c (CloneNamespace): Fixed potential memory leak due to a missing call of "Tcl_DStringFree". Reported by Greg Thompson <gst@cisco.com>. * generic/tclBasic.c (CloneCommand): Moved code adding the clone to its command table to the end of the command. This makes cleanup in case of a failure easier, there is less to roll back. Added code to release the command strcuture if cloning the procedure structures fails. changed from void to int, returning a TCL_ result code. (CloneNamespace): Changed from void to int, returning a TCL_ result code. Now reacting to the result of CloneCommand (and itself), aborts operation in case of a failure. (Tcl_CloneInterp): Now reacting to a failure reported by 'CloneNamespace'. Frees the fixup information accumulated so far (via new CloneFixupFree), then deletes the partially created interpreter via the standard 'Tcl_DeleteInterp'. (CloneFixupFree): New function, freeing the fixup information.

* * generic/tclCompile.c (TclCleanupByteCode): When encountering aandreas_kupries2002-12-065-10/+57
| | | | | | | | | | | | | | | | | shared bytecode structure we have to scan the literal table in that structure for objects of type "cmdName". These objects hold references to command structures, possibly in a different interp, and interfere with the cleanup of the refered commands (they keep their refcount up). Essentially at least one interp in a set of clones has a circular reference comand -> proc -> bytecode -> bytecode data -> cmdName obj -> command which prevents the command int that interp from being freed, leaking memory. The solution employed here is to invalidate the internal representation of 'cmdName's (but keeping the string rep), driving the refcount of refered command structures down, and breaking the cycle.

* * generic/tclBasic.c (Tcl_CloneInterp): Moved 'TclCreateExecEnv'andreas_kupries2002-11-262-10/+19
| | | | | | | | behind 'CloneNamespace'. This fixes the last leak found. The function creates a variable 'tcl_traceExec', and links a C variable to it. Running 'CloneNamespace' afterward overwrites the pointer, leaking the structure created by 'TclCreateExecEnv'.
* * tclBasic.c (CloneVariable): The initialization of the refCountandreas_kupries2002-11-263-3/+16
| | | | | | | | for the cloned variable assumed that all variables are namespace variables. This is not true. Globals are not marked as in a namespace. This caused the system to skip freeing all global variables in a cloned interpreter. Changed to explicitly check the variable if it is namespace'd.

Make EvalStats command use sprintf instead of fprintf for format printing to support IOS. (TclExecuteByteCode): TCL_THREAD_LITERALS support (TclCompileByteCodesForEval): simplify code and remove final else/if case that should never be true (repeat check of iPtr and epoch).
