Libgc download

I already posted all I have in a previous mail:. Just for the record: Ludo added libgc-8 in. It's not yet used,. As discussed yesterday on guix, I tried this:. Guile 3. Could it be a heap. This is exactly the error I see on Tumbleweed and what this issue is. Thanks for providing the reproducer! With Guile 3. Could you confirm that it works for you? That's working for me.

I built guix with guile 3. Thank you, Ludovic! Closing this bug now :. Woohoo, thanks for checking! Your comment.

This issue is archived. Nemanja Trifunovic. I find this very surprising. Is this your subjective feeling, or you actually measured project times? In my experience, GC and the choice of programming language in general has very little to do with productivity, except maybe with very small projects. My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it. Real measurement. The bigger the project is, the more time we spent dealing with memory errors.

With garbage collection, all this time is spent productively. That's interesting. I use smart pointers usually not reference counted , and STL containers, so I hardly ever have to explicitely call delete. Do you normally use plain pointers when not using your GC to get this improvement?

Same here. Haven't had a memory problem for ages. Re: Garbage Achilleas Margaritis 4-Aug Our applications have various types of object models with parent-child relations and many other types of cyclic relations, such as circular lists ; smart pointers can't be used there. It's interesting that neither STL nor boost seem to have a circular list template.

I've used std::list for that, with special functions to get next and previous elements in a circular manner, but it seems that a container could be designed to make this easier. I notice you mentioned parent-child relationships.

It seems to me that smart pointers and containers can easily handle such a relationship. If a parent object uses scoped pointers to point to its children, or keeps them in an STL container, the child objects will automatically be deleted when the parent is. In general, I try to give child objects as little information as possible about their parents in order to make them more reuseable.

Nathan HOlt. It's interesting that neither STL nor boost seem to have a circular list template I've made one myself. It seems to me that smart pointers and containers can easily handle such a relationship Nope, they can't. In general, me too. But in practice, children need to address the parent's interfaces, so it is not so easy.

There is also the other problem of double deletions. When I talk about GC, I never throw out other memory management solutions. It happens that GC is the easiest to use and most generic solution, though. I see what you meant by double deletions. I don't think I've ever created a reference counted object on the stack.

For that matter, hardly any of my reference counted objects have contained reference counting pointers. Re: Garbage Achilleas Margaritis 5-Aug If the pointer to the parent is needed, why should it be a smart pointer?

Because something else might point to parent with a shared pointer. You don't have compile-time access to the interfaces of either the caller or the callee. It all depends on what you are doing. What I showed you was just an example; an inexperienced programmer might declare a reference-counted object on the stack.

In one of the apps for our customers, we had a large object model with many inter-relationships between classes, and smart pointers created many problems.

GC is not a panacea, but it is a good solution that is generic enough to: 1 not demand specific constructs 2 allow for retrofitting of previously written programs It is a fire-and-forget solution with specific advantages and a few sort disadvantages.

I don't understand that. If the parent is tracked with shared pointers, it shouldn't make much difference, since when the last shared pointer is destroyed and the parent object is deleted, it should still delete the child object, along with the reference.

If the child object is shared, the parent can still tell the child to remove its reference one way or another. There are a number of classes around to automate this.

I am not sure what you mean by this. The system I rolled for myself was template based and strongly typed. I used it because it made it easy to design the child object without relying on details of the parent, thus making the child reuseable.

That makes sense. I guess being the only programmer at my company saves me from that. Fortunately, I've been able to force the object models of my projects into a hierarchy that saves me from the worst of the inter-relationships.

I don't think I've ever worked on a really large project. I'm sure its useful, but I don't think its quite a fire and forget solution. Even when deleting objects in the order that they're allocated, I think its possible to end up with a destructor trying to delete an object that's already deleted. For instance, std::list::splice can move elements from one list to another.

I'll admit that some of my suspicions come from issues with. In particular, finalizers have to assume that all the pointers are invalid, because the GC may have already deleted them. Sure there are, but in order to avoid the fuss, I prefer GC. The child needs to call methods of the parent. I understand your position. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process.

If you are not currently backing up your data, you need to do so immediately.
