-Garbage collector configuration
-===============================
+Garbage collector documentation and configuration
+=================================================
+
+
+Incminimark
+-----------
+
+PyPy's default garbage collector is called incminimark - it's an incremental,
+generational moving collector. Here we hope to explain a bit how it works
+and how it can be tuned to suit the workload.
+
+Incminimark first allocates objects in so called *nursery* - place for young
+objects, where allocation is very cheap, being just a pointer bump. The nursery
+size is a very crucial variable - depending on your workload (one or many
+processes) and cache sizes you might want to experiment with it via
+*PYPY_GC_NURSERY* environment variable. When the nursery is full, there is
+performed a minor collection. Freed objects are no longer referencable and
+just die, just by not being referenced any more; on the other hand, objects
+found to still be alive must survive and are copied from the nursery
+to the old generation. Either to arenas, which are collections
+of objects of the same size, or directly allocated with malloc if they're
+larger. (A third category, the very large objects, are initially allocated
+outside the nursery and never move.)
+
+Since Incminimark is an incremental GC, the major collection is incremental,
+meaning there should not be any pauses longer than 1ms.
+
+
+Fragmentation
+-------------
+
+Before we discuss issues of "fragmentation", we need a bit of precision.
+There are two kinds of related but distinct issues:
+
+* If the program allocates a lot of memory, and then frees it all by
+ dropping all references to it, then we might expect to see the RSS
+ to drop. (RSS = Resident Set Size on Linux, as seen by "top"; it is an
+ approximation of the actual memory usage from the OS's point of view.)
+ This might not occur: the RSS may remain at its highest value. This
+ issue is more precisely caused by the process not returning "free"
+ memory to the OS. We call this case "unreturned memory".
+
+* After doing the above, if the RSS didn't go down, then at least future
+ allocations should not cause the RSS to grow more. That is, the process
+ should reuse unreturned memory as long as it has got some left. If this
+ does not occur, the RSS grows even larger and we have real fragmentation
+ issues.
+
+
+gc.get_stats
+------------
+
+There is a special function in the ``gc`` module called
+``get_stats(memory_pressure=False)``.
+
+``memory_pressure`` controls whether or not to report memory pressure from
+objects allocated outside of the GC, which requires walking the entire heap,
+so it's disabled by default due to its cost. Enable it when debugging
+mysterious memory disappearance.
+
+Example call looks like that::
+
+ >>> gc.get_stats(True)
+ Total memory consumed:
+ GC used: 4.2MB (peak: 4.2MB)
+ in arenas: 763.7kB
+ rawmalloced: 383.1kB
+ nursery: 3.1MB
+ raw assembler used: 0.0kB
+ memory pressure: 0.0kB
+ -----------------------------
+ Total: 4.2MB
+
+ Total memory allocated:
+ GC allocated: 4.5MB (peak: 4.5MB)
+ in arenas: 763.7kB
+ rawmalloced: 383.1kB
+ nursery: 3.1MB
+ raw assembler allocated: 0.0kB
+ memory pressure: 0.0kB
+ -----------------------------
+ Total: 4.5MB
+
+In this particular case, which is just at startup, GC consumes relatively
+little memory and there is even less unused, but allocated memory. In case
+there is a lot of unreturned memory or actual fragmentation, the "allocated"
+can be much higher than "used". Generally speaking, "peak" will more closely
+resemble the actual memory consumed as reported by RSS. Indeed, returning
+memory to the OS is a hard and not solved problem. In PyPy, it occurs only if
+an arena is entirely free---a contiguous block of 64 pages of 4 or 8 KB each.
+It is also rare for the "rawmalloced" category, at least for common system
+implementations of ``malloc()``.
+
+The details of various fields:
+
+* GC in arenas - small old objects held in arenas. If the amount "allocated"
+ is much higher than the amount "used", we have unreturned memory. It is
+ possible but unlikely that we have internal fragmentation here. However,
+ this unreturned memory cannot be reused for any ``malloc()``, including the
+ memory from the "rawmalloced" section.
+
+* GC rawmalloced - large objects allocated with malloc. This is gives the
+ current (first block of text) and peak (second block of text) memory
+ allocated with ``malloc()``. The amount of unreturned memory or
+ fragmentation caused by ``malloc()`` cannot easily be reported. Usually
+ you can guess there is some if the RSS is much larger than the total
+ memory reported for "GC allocated", but do keep in mind that this total
+ does not include malloc'ed memory not known to PyPy's GC at all. If you
+ guess there is some, consider using `jemalloc`_ as opposed to system malloc.
+
+.. _`jemalloc`: http://jemalloc.net/
+
+* nursery - amount of memory allocated for nursery, fixed at startup,
+ controlled via an environment variable
+
+* raw assembler allocated - amount of assembler memory that JIT feels
+ responsible for
+
+* memory pressure, if asked for - amount of memory we think got allocated
+ via external malloc (eg loading cert store in SSL contexts) that is kept
+ alive by GC objects, but not accounted in the GC
+

+Environment variables
+---------------------
PyPy's default ``incminimark`` garbage collector is configurable through
several environment variables:
``PYPY_GC_NURSERY``
The nursery size.
- Defaults to 1/2 of your cache or ``4M``.
+ Defaults to 1/2 of your last-level cache, or ``4M`` if unknown.
Small values (like 1 or 1KB) are useful for debugging.

Installing external packages
----------------------------
-On Windows, there is no standard place where to download, build and
-install third-party libraries. We recommend installing them in the parent
-directory of the pypy checkout. For example, if you installed pypy in
-``d:\pypy\trunk\`` (This directory contains a README file), the base
-directory is ``d:\pypy``. You must then set the
-INCLUDE, LIB and PATH (for DLLs) environment variables appropriately.
+We uses a `repository` parallel to pypy to hold binary compiled versions of the
+build dependencies for windows. As part of the `rpython` setup stage,
environment
+variables will be set to use these dependencies. The repository has a README
+file on how to replicate, and a branch for each supported platform. You may run
+ the `get_externals.py` utility to checkout the proper branch for your platform
+and PyPy version.

-Abridged method (using Visual Studio 2008)
-------------------------------------------
-
-Download the versions of all the external packages from
-https://bitbucket.org/pypy/pypy/downloads/local_59.zip
-(for post-5.8 builds) with sha256 checksum
-``6344230e90ab7a9cb84efbae1ba22051cdeeb40a31823e0808545b705aba8911``

-https://bitbucket.org/pypy/pypy/downloads/local_2.4.zip
-(for 2.4 release and later) or
-https://bitbucket.org/pypy/pypy/downloads/local.zip
-(for pre-2.4 versions)
-Then expand it into the base directory (base_dir) and modify your environment
-to reflect this::
-
- set PATH=<base_dir>\bin;%PATH%
- set INCLUDE=<base_dir>\include;%INCLUDE%
- set LIB=<base_dir>\lib;%LIB%

-Now you should be good to go. If you choose this method, you do not need
-to download/build anything else.
