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.

Robert O'Callahan 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.

Robert O'Callahan 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.

Robert O'Callahan bd7f2d9ba4 Make `log_error()` work in a `Multithreaded` context. 
`log_error()` causes an exit so we don't have to try too hard here. The main
thing is to ensure that we normally are able to exit without causing a stack
overflow due to recursive asserts about not being in a `Multithreaded` context.

Robert O'Callahan 7af5dbae35 Add `IdString::unescape()` method
