[edk2-libc Patch v2 2/4] AppPkg/Applications/Python: to remove document references to py2.7.2

Jayaprakash, N

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3589

This commit is to remove references to the py 2.7.2 UEFI port
in all documents from edk2-libc repo. This python interpreter
is no more supported on UEFI shell due to availability of
py 3.6.8 on UEFI.

- EDK II Python
- ReadMe
- Version 2.7.2
- Release 1.02
- 18 Jan. 2013
-This document is devoted to general information on building and setup of the
-Python environment for UEFI 2.3, the invocation of the interpreter, and things
-that make working with Python easier.
-It is assumed that you already have either UDK2010 or a current snapshot of
-the EDK II sources from www.tianocore.org, and that you can successfully build
-packages within that distribution.
-2. Release Notes
- 1) All C extension modules must be statically linked (built in)
- 2) The site and os modules must exist as discrete files in ...\lib\python.27
- 3) User-specific configurations are not supported.
- 4) Environment variables are not supported.
-3. Getting and Building Python
- 3.1 Getting Python
- ==================
- For development ease, a subset of the Python 2.7.2 distribution has been
- included in the AppPkg source tree. If a full distribution is desired, the
- Python-2.7.2 directory can be removed or renamed and the full source code
- downloaded from http://www.python.org/ftp/python/2.7.2/.
- A. Within your EDK II development tree, extract the Python distribution into
- AppPkg/Applications/Python. This should create the
- AppPkg/Applications/Python/Python-2.7.2 directory.
- B. Copy the files from PyMod-2.7.2 into the corresponding directories within
- the Python-2.7.2 tree. This will overwrite existing files with files
- modified for UEFI usage.
- 3.2 Building Python
- ===================
- A. Edit Efi/config.c to enable the built-in modules you need.
- Mandatory Built-in Modules:
- edk2 errno imp marshal
- Additional built-in modules which are required to use the help()
- functionality provided by PyDoc, are:
- _codecs _collections _functools _random
- _sre _struct _weakref binascii
- cStringIO gc itertools math
- operator time
- B. Edit AppPkg/AppPkg.dsc to enable (uncomment) the PythonCore.inf line
- within the [Components] section.
- C. Build AppPkg, which includes Python, using the standard "build" command:
- For example, to build Python for an X64 CPU architecture:
- build -a X64 -p AppPkg\AppPkg.dsc
-4. Python-related paths and files
-Python depends upon the existence of several directories and files on the
-target system.
- \EFI Root of the UEFI system area.
- |- \Tools Location of the Python.efi executable.
- |- \Boot UEFI specified Boot directory.
- |- \StdLib Root of the Standard Libraries sub-tree.
- |- \etc Configuration files used by libraries.
- |- \tmp Temporary files created by tmpfile(), etc.
- |- \lib Root of the libraries tree.
- |- \python.27 Directory containing the Python library
- | modules.
- |- \lib-dynload Dynamically loadable Python extensions.
- |- \site-packages Site-specific packages and modules.
-5. Installing Python
-These directories, on the target system, are populated from the development
-system as follows:
- * \Efi\Tools receives a copy of Build/AppPkg/DEBUG_VS2005/X64/Python.efi.
- ^^^^^ ^^^^^^^^^^
- Modify the host path to match the your build type and compiler.
- * The \Efi\StdLib\etc directory is populated from the StdLib/Efi/StdLib/etc
- source directory.
- * Directory \Efi\StdLib\lib\python.27 is populated with packages and modules
- from the AppPkg/Applications/Python/Python-2.7.2/Lib directory.
- The recommended minimum set of modules (.py, .pyc, and/or .pyo):
- os stat ntpath warnings traceback
- site types copy_reg linecache genericpath
- * Python C Extension Modules built as dynamically loadable extensions go into
- the \Efi\StdLib\lib\python.27\lib-dynload directory. This functionality is
- not yet implemented.
-6. Example: Enabling socket support
- 1. enable {"_socket", init_socket}, in Efi\config.c
- 2. enable Python-2.7.2/Modules/socketmodule.c in PythonCore.inf.
- 3. copy socket.py over to /Efi/StdLib/lib/python.27 on your target system.
- 4. Make sure dependent modules are present(.py) or built in(.c):
- functools, types, os, sys, warnings, cStringIO, StringIO, errno
- 5. build -a X64 -p AppPkg\AppPkg.dsc
- 6. copy Build\AppPkg\DEBUG_VS2005\X64\Python.efi to \Efi\Tools on your
- target system. Replace "DEBUG_VS2005\X64", in the source path, with
- values appropriate for your tool chain and processor architecture.
-7. Running Python
- Python must currently be run from an EFI FAT-32 partition, or volume, under
- the UEFI Shell. At the Shell prompt enter the desired volume name, followed
- by a colon ':', then press Enter. Python can then be executed by typing its
- name, followed by any desired options and arguments.
- 2.0 Shell> fs0:
- 2.0 FS0:\> python
- Python 2.7.2 (default, Oct 13 2015, 16:21:53) [C] on uefi
- Type "help", "copyright", "credits" or "license" for more information.
- >>> exit()
- 2.0 FS0:\>
- Python, as distributed, sends its interactive prompts to stderr. If
- STDERR isn't enabled in UEFI Setup so that it's output goes to the
- console, it may appear that Python hangs on startup. If this happens,
- one may be able to rectify the condition by typing "exit()" followed
- by <enter> to exit out of Python. Then, type "exit" at the Shell prompt
- which should enter Setup where you can use the Boot Maintenance
- Manager to modify your Console settings.
- Some platforms don't include the Setup utility, or don't allow STDERR to
- be modified. In these cases, Python may be started with the '-#' option
- which will cause stderr to be the same as stdout and should allow
- Python to be used interactively on those platforms.
- Depending upon the version of Shell you are using, it may be necessary
- to escape the '#' character so that the Shell doesn't interpret it as
- the start of a comment. The escape character is '^'.
- Example:
- python -^# -V
