docs: Resolving todos 
Make explicit the location for the `CMakeUserPresets.json` file.
Update docs tests documentation.
Move `BUILD_DIR` and `PROGRAM_PREFIX` comments into the functional tests todo.
Add cmake to MacPorts/FreeBSD install instructions.
Add ccache to example `CMakeUserPresets.json` (it isn't otherwise documented, and is no longer as obvious without an `ENABLE_CCACHE` makevar).

register.cc: Make cmd paths proximate 
The CMake refactor changes relative paths to absolute when calling `source_location::current()`.  Use the path to `register.cc` to find the root yosys dir, and use that as the base for other paths.
Includes provisions for when plugins have a valid location; if it's not in the yosys source tree we shouldn't try to make the path relative, and we shouldn't try to auto group by path (since such groups will never be allocated, leaving them as unknown is preferable).
Limited to non wasm (I think that's the only one where we can't (easily) use `<filesystem>`). But where we do use `<filesystem>` we can also simplify the auto group to use `fs::path::parent_path()`.

Catherine afc0e78d11 Update top-level Python project for CMake compatibility. 
This commit reimplements the (no longer recommended) setuptools based
build system using a standards-based in-tree PEP517 build backend.
The implementation is partially based on
  https://codeberg.org/ziglang/zig-pypi/src/branch/main/make_wheels.py
which is licensed under BSD-0-clause.

It also adds a new option `YOSYS_BUILD_PYTHON_ONLY` that is available
only if the binary or the library aren't going to be installed, which
turns off these targets entirely, as well as some dependent ones
(e.g. tests).

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.
