# LGPL and another free license we'd need to ask spot about are present in some

# High-level configuration of the build:

# PyPy consists of an implementation of an interpreter (with JIT compilation)
# for the full Python language  written in a high-level language, leaving many
# of the implementation details as "pluggable" policies.
#
# The implementation language is then compiled down to .c code, from which we
# obtain a binary.
#
# This allows us to build a near-arbitrary collection of different
# implementations of Python with differing tradeoffs
#
# (As it happens, the implementation language is itself Python, albeit a
# restricted subset "RPython", chosen to making it amenable to being compiled.
# The result implements the full Python language though)

# We could build many different implementations of Python.
# For now, let's focus on the implementation that appears to be receiving the
# most attention upstream: the JIT-enabled build, with all standard
# optimizations

# Building a configuration can take significant time:

# A build of pypy (with jit) on i686 took 77 mins:

  # The build involves invoking a python script, passing in particular
  # arguments, environment variables, etc.
  # Some notes on those follow:

  # The generated binary embeds copies of the values of all environment
  # variables.  We need to unset "RPM_BUILD_ROOT" to avoid a fatal error from
  #  /usr/lib/rpm/check-buildroot
  # during the postprocessing of the rpmbuild, complaining about this
  # reference to the buildroot


  # By default, pypy's autogenerated C code is placed in
  #    /tmp/usession-N
  #  
  # and it appears that this stops rpm from extracting the source code to the
  # debuginfo package
  #
  # The logic in pypy-1.4/pypy/tool/udir.py indicates that it is generated in:
  #    $PYPY_USESSION_DIR/usession-$PYPY_USESSION_BASENAME-N    
  # and so we set PYPY_USESSION_DIR so that this tempdir is within the build
  # location, and set $PYPY_USESSION_BASENAME so that the tempdir is unique
  # for each invocation of BuildPyPy

  # Compilation flags for C code:
  #   pypy-1.4/pypy/translator/c/genc.py:gen_makefile
  # assembles a Makefile within

  # calling out to platform.gen_makefile
  # For us, that's
  #   pypy-1.4/pypy/translator/platform/linux.py: class BaseLinux(BasePosix):
  # which by default has:
  #   CFLAGS = ['-O3', '-pthread', '-fomit-frame-pointer',
  #             '-Wall', '-Wno-unused']

# pypy uses .pyc files by default (--objspace-usepycfiles), but has a slightly
# different bytecode format to CPython.  It doesn't use .pyo files: the -O flag
# is treated as a "dummy optimization flag for compatibility with C Python"
#
# pypy-1.4/pypy/module/imp/importing.py has this comment:
    # XXX picking a magic number is a mess.  So far it works because we
    # have only two extra opcodes, which bump the magic number by +1 and
    # +2 respectively, and CPython leaves a gap of 10 when it increases
    # its own magic number.  To avoid assigning exactly the same numbers
    # as CPython we always add a +2.  We'll have to think again when we
    # get at the fourth new opcode :-(
    #
    #  * CALL_LIKELY_BUILTIN    +1
    #  * CALL_METHOD            +2
    #
    # In other words:
    #
    #     default_magic        -- used by CPython without the -U option
    #     default_magic + 1    -- used by CPython with the -U option
    #     default_magic + 2    -- used by PyPy without any extra opcode
    #     ...
    #     default_magic + 5    -- used by PyPy with both extra opcodes
#

# pypy-1.4/pypy/interpreter/pycode.py has:
#
#  default_magic = (62141+2) | 0x0a0d0000                  # this PyPy's magic
#                                                          # (62131=CPython 2.5.1)
# giving a value for "default_magic" for PyPy of 0xa0df2bf.
# Note that this corresponds to the "default_magic + 2" from the comment above

# In my builds:
#   $ ./pypy --info | grep objspace.opcodes
#                objspace.opcodes.CALL_LIKELY_BUILTIN: False
#                        objspace.opcodes.CALL_METHOD: True
# so I'd expect the magic number to be:
#    0x0a0df2bf + 2 (the flag for CALL_METHOD)
# giving
#    0x0a0df2c1
#
# I'm seeing
#   c1 f2 0d 0a
# as the first four bytes of the .pyc files, which is consistent with this.


# Bytecompile all of the .py files we ship, using our pypy binary, giving us
# .pyc files for pypy.  The script actually does the work twice (passing in -O
# the second time) but it's simplest to reuse that script.
#
# The script has special-casing for .py files below
#    /usr/lib{64}/python[0-9].[0-9]
# but given that we're installing into a different path, the supplied "default"
# implementation gets used instead.
#
# Note that some of the test files deliberately contain syntax errors, so
# we pass 0 for the second argument ("errors_terminate"):

datadir; patch app_main.py to look in this installation location first when

build issues)
- add more comments, and update others to reflect 1.2 -> 1.4 changes

- add the LICENSE and README to all subpackages
- ensure the built binaries don't have the "I need an executable stack" flag
