To get an optimized build of Python, ``configure --enable-optimizations`` -before you run ``make``. This sets the default make targets up to enable -Profile Guided Optimization (PGO) and may be used to auto-enable Link Time -Optimization (LTO) on some platforms. For more details, see the sections -below. - -Profile Guided Optimization -^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -PGO takes advantage of recent versions of the GCC or Clang compilers. If used, -either via ``configure --enable-optimizations`` or by manually running -``make profile-opt`` regardless of configure flags, the optimized build -process will perform the following steps: - -The entire Python directory is cleaned of temporary files that may have -resulted from a previous compilation. - -An instrumented version of the interpreter is built, using suitable compiler -flags for each flavor. Note that this is just an intermediary step. The -binary resulting from this step is not good for real-life workloads as it has -profiling instructions embedded inside. - -After the instrumented interpreter is built, the Makefile will run a training -workload. This is necessary in order to profile the interpreter's execution. -Note also that any output, both stdout and stderr, that may appear at this step -is suppressed. - -The final step is to build the actual interpreter, using the information -collected from the instrumented one. The end result will be a Python binary -that is optimized; suitable for distribution or production installation. - - -Link Time Optimization -^^^^^^^^^^^^^^^^^^^^^^ - -Enabled via configure's ``--with-lto`` flag. LTO takes advantage of the -ability of recent compiler toolchains to optimize across the otherwise -arbitrary ``.o`` file boundary when building final executables or shared -libraries for additional performance gains. - - -What's New ----------- - -We have a comprehensive overview of the changes in the `What's New in Python -3.13 `_ document. For a more -detailed change log, read `Misc/NEWS -`_, but a full -accounting of changes can only be gleaned from the `commit history -`_. - -If you want to install multiple versions of Python, see the section below -entitled "Installing multiple versions". - - -Documentation -------------- - -`Documentation for Python 3.13 `_ is online, -updated daily. - -It can also be downloaded in many formats for faster access. The documentation -is downloadable in HTML, PDF, and reStructuredText formats; the latter version -is primarily for documentation authors, translators, and people with special -formatting requirements. - -For information about building Python's documentation, refer to `Doc/README.rst -`_. - - -Testing -------- - -To test the interpreter, type ``make test`` in the top-level directory. The -test set produces some output. You can generally ignore the messages about -skipped tests due to optional features which can't be imported. If a message -is printed about a failed test or a traceback or core dump is produced, -something is wrong. - -By default, tests are prevented from overusing resources like disk space and -memory. To enable these tests, run ``make buildbottest``. - -If any tests fail, you can re-run the failing test(s) in verbose mode. For -example, if ``test_os`` and ``test_gdb`` failed, you can run:: - - make test TESTOPTS="-v test_os test_gdb" - -If the failure persists and appears to be a problem with Python rather than -your environment, you can `file a bug report -`_ and include relevant output from -that command to show the issue. - -See `Running & Writing Tests `_ -for more on running tests. - -Installing multiple versions ----------------------------- - -On Unix and Mac systems if you intend to install multiple versions of Python -using the same installation prefix (``--prefix`` argument to the configure -script) you must take care that your primary python executable is not -overwritten by the installation of a different version. All files and -directories installed using ``make altinstall`` contain the major and minor -version and can thus live side-by-side. ``make install`` also creates -``${prefix}/bin/python3`` which refers to ``${prefix}/bin/python3.X``. If you -intend to install multiple versions using the same prefix you must decide which -version (if any) is your "primary" version. Install that version using -``make install``. Install all other versions using ``make altinstall``. - -For example, if you want to install Python 2.7, 3.6, and 3.13 with 3.13 being the -primary version, you would execute ``make install`` in your 3.13 build directory -and ``make altinstall`` in the others. - - -Release Schedule ----------------- - -See :pep:`719` for Python 3.13 release details. - - -Copyright and License Information ---------------------------------- - - -Copyright © 2001-2024 Python Software Foundation.
