Hello everyone.
I have written a garbage collector for standard C++ application. It has
following main features.
1) Deterministic Finalization
Providing deterministic finalization, the system can manage resources
as well as objects. The programming style is clear and easy, conforming
to RAII (Resource Acquisition Is Initialization) idiom of C++
programmers. The memory usage is very efficient, acyclic garbage is

I have been reading (or at least googling) about the potential addition
of optional garbage collection to C++0x. There are numerous myths and
whatnot with very little detailed information.
Will this work be library based or language based and will it be based
on that of managed C++? Then of course there are the finer technical
questions raised (especially due to pointer abuse). Is a GC for C++
just a pipe dream or is there a lot of work...

Abstract
--------
Garbage collection is a method of managing memory by using a "collector"
library. Periodically, or triggered by an allocation request, the
collector looks for unused memory chunks and recycles them.
This memory allocation strategy has been adapted to C (and C++) by the
library written by Hans J Boehm and Alan J Demers.
Why a Garbage Collector?

Hi everyone,
A program that I'm helping to code seems to slow down drastically
during initialisation, and looking at the profiling graph, it seems to
be the garbage collector thats slowing things down. I must point out
that a heck of a lot of data are being read in and manipulated, and I
was wondering if there were any metrics to show much of a performance
hit is occurring during the initialisation? If it turns out that the
GC is having a...

I'am not sure what to think about the Garbage Collector.
I have a Class OutlookObject, It have two private variables.
Private Microsoft.Office.Interop.Outlook.Application _Application = null;
Private Microsoft.Office.Interop.Outlook.NameSpace _Namespace = null;
The Constructor:

My first stab at a suggestion would be to adjust the threshold

collects no objects, double (or whatever) the threshold until the next

Hello,
traditionally, in C++, dynamically allocated memory has been
managed explicitly by calling "delete" in the application code.
Now, in addition to the standard library strings, containers, and
auto_ptrs, gurus suggest that may be better to use a reference-counted
smart pointer, or a garbage-collector.
But in which cases it is better to use one technique and in which cases
another? IOW, which is the design criterion?

Hello everybody,
To test the python 2.5 garbage collector, I wrote a trivial script
allocating dummy objects of various sizes, then forgetting them in a loop.
The garbage collector seems working well, limiting the memory used.
But I've noticed a near linear slowdown of the execution : after a few
minutes - and several millions of allocated and freed objects, each
iteration take more and more time to execute.

On a related note, there have been past threads reporting that
allocating and freeing increasingly long arrays, especially of tuples
(as I remember) can take more than linearly increasing time. The
solution was to turn off gc during the allocation phase so it did not
get triggered and spend increasing long times searching for collectible
objects when there were not any.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
