-Making a PyPy Release
-=====================
+The PyPy Release Process
+========================
+
+Release Policy
+++++++++++++++
+
+We try to create a stable release a few times a year. These are released on
+a branch named like release-2.x or release-4.x, and each release is tagged,
+for instance release-4.0.1.
+
+After release, inevitably there are bug fixes. It is the responsibility of
+the commiter who fixes a bug to make sure this fix is on the release branch,
+so that we can then create a tagged bug-fix release, which will hopefully
+happen more often than stable releases.
+
+How to Create a PyPy Release
+++++++++++++++++++++++++++++

+## Implementation of PyStringObject
+## ================================
+##
+## The problem
+## -----------
+##
+## PyString_AsString() must return a (non-movable) pointer to the underlying
+## buffer, whereas pypy strings are movable. C code may temporarily store
+## this address and use it, as long as it owns a reference to the PyObject.
+## There is no "release" function to specify that the pointer is not needed
+## any more.
+##
+## Also, the pointer may be used to fill the initial value of string. This is
+## valid only when the string was just allocated, and is not used elsewhere.
+##
+## Solution
+## --------
+##
+## PyStringObject contains two additional members: the size and a pointer to a
+## char buffer; it may be NULL.
+##
+## - A string allocated by pypy will be converted into a PyStringObject with a
+## NULL buffer. The first time PyString_AsString() is called, memory is
+## allocated (with flavor='raw') and content is copied.
+##
+## - A string allocated with PyString_FromStringAndSize(NULL, size) will
+## allocate a PyStringObject structure, and a buffer with the specified
+## size, but the reference won't be stored in the global map; there is no
+## corresponding object in pypy. When from_ref() or Py_INCREF() is called,
+## the pypy string is created, and added to the global map of tracked
+## objects. The buffer is then supposed to be immutable.
+##
+## - _PyString_Resize() works only on not-yet-pypy'd strings, and returns a
+## similar object.
+##
+## - PyString_Size() doesn't need to force the object.
+##
+## - There could be an (expensive!) check in from_ref() that the buffer still
+## corresponds to the pypy gc-managed string.
