Garbage Collection in C

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?
-----------------------
Standard C knows only the malloc/calloc/free functions. The programmer
must manage each block of memory it allocates, never forgetting to call
the standard function free() for each block. Any error is immediately
fatal, but helas, not with immediate consequences. Many errors like
freeing a block twice (or more) or forgetting to free an allocated
block will be discovered much later (if at all). This type of bugs are
very difficult to find and a whole industry of software packages
exists just to find this type of bugs.

The garbage collector presents a viable alternative to the traditional
malloc/free "manual" allocation strategies. The allocator of Boehm
tries to find unused memory when either an allocation request is
done, or when explicitely invoked by the programmer.

The main advantage of a garbage collector is that the programmer is
freed from the responsability of allocating/deallocating memory. The
programmer requests memory to the GC, and then the rest is *automatic*.
Limitations of the GC.
---------------------
The GC needs to see all pointers in a program. Since it scans
periodically memory, it will assume that any block in its block list is
free to reuse when it can't find any pointers to it. This means that the
programmer can't store pointers in the disk, or in the "windows extra
bytes", as it was customary to do under older windows versions, or
elsewhere.

This is actually not a limitation since most programs do not write
pointers to disk, and expect them to be valid later...
Obviously, there is an infinite way to hide pointers (by XORing them
with some constant for instance) to hide them from the collector.

This is of no practical significance. Pointers aren't XORed in normal
programs, and if you stay within the normal alignment requirements
of the processor, everything works without any problems.

Performance considerations
--------------------------
In modern workstations, the time needed to make a complete sweep in
mid-size projects is very small, measured in some milliseconds. In
programs that are not real time the GC time is completely undetectable.
I have used Boehm's GC in the IDE of lcc-win32, specially in the
debugger. Each string I show in the "automatic" window is allocated
using the GC. In slow machines you can sometimes see a pause of
less than a second, completely undetectable unless you know that is
there and try to find it.

It must be said too that the malloc/free system is slow too, since at
each allocation request malloc must go through the list of free blocks
trying to find a free one. Memory must be consolidated too, to avoid
fragmentation, and a malloc call can become very expensive, depending
on the implementation and the allocation pattern done by the program.
Portability
-----------
Boehm's GC runs under most standard PC and UNIX/Linux platforms. The
collector should work on Linux, *BSD, recent Windows versions, MacOS X,
HP/UX, Solaris, Tru64, Irix and a few other operating systems. Some
ports are more polished than others. There are instructions for porting
the collector to a new platform. Kenjiro Taura, Toshio Endo, and Akinori
Yonezawa have made available a parallel collector.

Conclusions
-----------
The GC is a good alternative to traditional allocation strategies for C
(and C++). The main weakness of the malloc/free system is that it
doesn't scale. It is impossible to be good at doing a mind numbing task
without any error 100% of the time. You can be good at it, you can be
bad at it, but you can NEVER be perfect. It is human nature.

The GC frees you from those problems, and allows you to conecntrate in
the problems that really matter, and where you can show your strength
as software designer. It frees you from the boring task of keeping track
of each memory block you allocate.

The program must have live pointers in its address space, or
somehow attached to it. For example write the pointer to disk
and erase the in-memory copy will lose the block. If windows
hides pointers outside the address space, you lose.

# >Casts to integers do not affect the GC at all.
#
# Amazing. How does the GC deal with the fact that on a number of
# systems, pointers are 64 bits, but 'int' is only 32 bits ?

It looks for byte strings subject to certain conditions that
look like heap addresses. If you change a pointer so that it
is no longer recognisable, you lose.

# And how does it deal with representation changes that can occur
# when casting pointers? About all the C89 standard promises is that

If the string of bytes making up the address value remain
recognisable, it can sweep and mark. If not, you lose.

Boehm-Demers segregates blocks to pages by block size. From a
pointer you get the page addres; from the page, the block size;
then the block first byte address. Interior block pointers do
not cause problems. Converting the addresses to something
unrecognisable causes problems.

# e) function pointers are not object pointers and nothing in the
# C89 standard requires that they be convertable to any kind of object
# pointer, including no requirement at any level that converting them
# to void* will work.

Code, own variables, heap, and stack are different parts of the
address space. Most operating systems give you some kind of map
from page addresses to memory area.

# All is vanity. -- Ecclesiastes

We are all bytes in the wind.

Boehm-Demers garbage collection doesn't work for all programs on
all systems. The systems it has been ported to do work (ie they
have been verified with system libraries and compilers) if you
write your programs in the restricted language.

Personally I'm not interested in exotic and/or program-me-if-you-dare
systems. And I do not find the rules difficult to follow.

garbage. For example, you can attach a file closer to a file object.

EXACTLY.

It is amazing how deep the implications of this go. For instance, it
has been argued that you need constructors/destructors to support
operator overloading in C, since operator overloading needs to destroy
intermediate objects in expressions:
c = (a+b)/(a-b);
when '+' is overloaded, it must create a temporary object. This is
possible using the GC, since you are sure the GC will find the
unneeded object.

An enormous system of tables (DWARF3 tables) has been developed to
handle the throw/catch problem of C++. When you make a throw, the
destructors must be called to free the memory. All this is again
unnecessary using the GC. You can use longjmp/throw/catch without any
fear of making amemory leak.

Note that DWARF3 tables can make 10% or more of the code size in C++
applications)

Passing buffers from one thread to another is much easier with the GC.
You do not need to care when your buffer is going to be reclaimed.
There is no need to synchronize threads and wait for them to use the
buffer. You can send the allocated buffer and forget about it, the GC
will reclaim it anyway.

ETC ETC ETC.

The GC simplifies complex programs in a BIG way. It makes many features
of C++ unnecessary. C is a different thing with the GC.

It encourages lax design & programming styles.

I hated it in java and I would hate it in C/C++.

We made do with centralised pool allocation/deallocation libraries and
careful matching of alloc/dealloc for years.

Being sreful whenver malloc was called also meant there was some
consideration for when to do it - we tended to be more tight with our
memory uses.

It suddenly seems very popular to assume anything using malloc is as
leaky as a sieve - it is simply not so.

C is C. Lets keep it that way. A real mans language .....

I did? First time I thought, anyway. However you want them to look.

There are laws : if you call them to allocate, you call them to
deallocate. The difference being that during program development you can
log/track accesses and discover the dangling pointers relatively
quickly : one of the main reasons for any level for abstraction. if your
system maintains a pool of runtime objects, allocate them from a
centralised, controlled pool.

Dont get me wrong : its not "very" easy. But then neither is good C programming
or good "any" programming for that

Nothing magic.

This involves a technical point of language design. Destructors
were added to C++ because it had no garbage collection. The
result is far more complicated language implementation which
can still has implicit storage management activated.

Not really. Garbage is automatically collected. You can fine-tune this,
specifying the threshold or call a gc when you think it is a good moment
to do that.
and the application doesn't run slower than hand
written malloc/free code,
No, it doesn't run slower. Allocation is a bit slower since each
allocation does a bit of a GC (incremental GC)
and there are no relatively long (compared to
free()) pauses while garbage collection goes on?
There are pauses, but in modern workstations this is barely noticeable.
wow that's phantastic and incredible.
Write in assembly. That's a *real* language :-)

Destructors do more than releasing memory. And finalisation is not a
good substitute for these tasks as finalisation is not synchronous.
