R Fork isn't needed at all really in the technique described, this is all that's needed: - Map a copy of the memory using copy-on-write - Run some code concurrently It just happens that fork does both of these things, but you can equally well do the two things using separate calls. In fact you should be able to avoid the deadlock issue by not using fork but just remapping some shared memory using copy on write. The GC can exist in a separate thread which pauses itself after every run. To run the GC it's then just a case of: - stop the world - copy registers to stack - remap shared memory using COW - resume the world - resume the GC thread And that would work on all modern OSes, plus you don't have the overhead of creating a new process or even a new thread. Also immutable memory doesn't need to be mapped, the GC thread can access it directly. I'm interested in what you're describing, but I don't know how can you achieve this without fork()ing (or clone()ing in Linux). What does remap shared memory using COW in a context where fork() doesn't happen? Why do you even need shared memory if fork() doesn't happen? If remap shared memory using COW means get a different address for the same block of memory until a write happens in that block, then you can't scan the roots anymore.

I noticed a subtle error in the response to the question on logical const (at 32:11). Specifically, overloading the function on immutable doesn't allow you to 'know' that the object you are passed is const or not, as prior to the invocation of the function (and thus overload determination) an immutable object could be bound to a const reference. As an alternative, IIRC, the RTTI of a class can be introspected inside the function to determine mutable/immutable at runtime.

I think a slice compares equal to null only if the pointer part is null. However, a slice with a null pointer and a length of zero is still a valid empty slice, which is slightly odd behaviour compared to other languages... An empty string literal initialises the pointer to non-null because string literals are null terminated, so the memory block actually has a length of one, even though the slice has length zero.

I'm *very* interested in your suggestion. I do mean mapping the same physical block of memory into two virtual memory blocks, such that a write will cause the OS to make a copy and sever the link. Given that we're dealing with significantly large blocks of memory all in multiples of the page size, it should be a simple matter to map from one copy of the memory to the other and back again using basic pointer arithmetic, so scanning the roots should not be a problem. You need shared memory because a file handle is needed when calling mmap to enable the COW functionality, and shared memory lets you get a file handle to a block of memory.

Eh, official definition of breaking change keeps breaking my heart. But I guess this is a mindset set in stone now and changing it is close to impossible. One positive thing to add, though: a question was asked about automatic tools that can make required changes automatically when something breaking is introduced. Starting if next release standard flag will appear that will list all places in code that are subject to specific behavior change: https://github.com/D-Programming-Language/dmd/pull/2039

spam trolls
We occasionally get a drive-by hosing with spam and trolling. Fortunately, not very often. When I see them, I just delete them from the server. If I miss one, please email me about it. Please do not reply to those posts. That's what they want. It confirms to them that they have an audience. It spreads their contagion, especially when your reply quotes the posts. I delete replies, too, as a general rule. If you want to talk about spam, start a new thread. Don't reply in the spam or troll threads, don't quote them, don't reply with do not feed the trolls posts, don't acknowledge them in any way. Oh, and I don't mind occasional off-topic posts from forum regulars.

Looking at their release history it doesn't look like they work on multiple titles at the same time (several years between each major title). Quantum Break doesn't come out until 2014 so I think it's a safe bet to say they are using D for a game featured prominently during a major console announcement. Very cool.
