Merge pull request #5803 from YosysHQ/emil/specrule-port-sanity 
Fix $specrule port naming inconsistency

Petter Reinholdtsen 89d360aa4a Rewrote Linux edition of proc_self_dirname() to handle any symlink length. 
This make sure the method work also when the program is located in
deep or long file paths, longer than both PATH_MAX and "getconf
PATH_MAX .".  Use the same code on GNU Hurd, where it now work.

I am not sure how to test this in a platform independent way.

Robert O'Callahan 290fb0556d Prevent race on `num_active_worker_threads_`. 
The core issue here is that we need to ensure `num_active_worker_threads_`
is read before incrementing `done_workers`. See the comments
added in this PR to explain why, and why the resulting code is
race-free.

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 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.
