Merge pull request #5728 from povik/tcl-set-result 
Replace deprecated Tcl API to fix use-after-free
 2026-03-06 13:36:48 +00:00
Martin Povišer
167c6c4585 Replace deprecated Tcl API to fix use-after-free 
Under Tcl 9.0 the Tcl_SetResult utility is a macro:

	#define Tcl_SetResult(interp, result, freeProc) \
		do { \
		    const char *__result = result; \
		    Tcl_FreeProc *__freeProc = freeProc; \
		    Tcl_SetObjResult(interp, Tcl_NewStringObj(__result, -1)); \
		    if (__result != NULL && __freeProc != NULL && __freeProc != TCL_VOLATILE) { \
			if (__freeProc == TCL_DYNAMIC) { \
			    Tcl_Free((char *)__result); \
			} else { \
			    (*__freeProc)((char *)__result); \
			} \
		    } \
		} while(0)

Temporaries constructed as part of the 'result' expression will be
dropped before the 'result' pointer is used. What was safe when
Tcl_SetResult was a function isn't safe with the macro definition.
Transition away from deprecated SetResult to calling
SetObjResult/MewStringObj directly.

72a21fe01d Introduce RmStats struct to encapsulate removal statistics 
Turns out this is not strictly necessary for this PR but it's
still a good thing to do and makes it clearer that the stats
are not modified in a possibly racy way.

c2bb7d6a82 Make keep_cache_t process all modules up-front instead of on-demand 
We will want to query `keep_cache` from parallel threads. If we compute
the results on-demand, that means we need synchronization for cache
access in those queries, which adds complexity and overhead. Instead, prefill
the cache with the status of all relevant modules. Note that this doesn't
actually do more work --- we always consult `keep_cache` for all cells of
all selected modules, so scanning all those cells and determining the kept
status of all dependency modules is always required.

Later in this PR we're going to parallelize `scan_module` itself, and that's also
much easier to do when no other parallel threads are running.
