Three types of modules concern us here: pure Python modules, - extension modules, and packages. - -pure Python module - a module written in Python and contained in a single :file:`.py` file (and - possibly associated :file:`.pyc` files). Sometimes referred to as a - "pure module." - -extension module - a module written in the low-level language of the Python implementation: C/C++ - for Python, Java for Jython. Typically contained in a single dynamically - loadable pre-compiled file, e.g. a shared object (:file:`.so`) file for Python - extensions on Unix, a DLL (given the :file:`.pyd` extension) for Python - extensions on Windows, or a Java class file for Jython extensions. (Note that - currently, the Distutils only handles C/C++ extensions for Python.) - -package - a module that contains other modules; typically contained in a directory in the - filesystem and distinguished from other directories by the presence of a file - :file:`__init__.py`. - -root package - the root of the hierarchy of packages. (This isn't really a package, since it - doesn't have an :file:`__init__.py` file. But we have to call it something.) - The vast majority of the standard library is in the root package, as are many - small, standalone third-party modules that don't belong to a larger module - collection. Unlike regular packages, modules in the root package can be found in - many directories: in fact, every directory listed in ``sys.path`` contributes - modules to the root package. - - -.. _distutils-term: - -Distutils-specific terminology -============================== - -The following terms apply more specifically to the domain of distributing Python -modules using the Distutils: - -module distribution - a collection of Python modules distributed together as a single downloadable - resource and meant to be installed *en masse*. Examples of some well-known - module distributions are NumPy, SciPy, Pillow, - or mxBase. (This would be called a *package*, except that term is - already taken in the Python context: a single module distribution may contain - zero, one, or many Python packages.) - -pure module distribution - a module distribution that contains only pure Python modules and packages. - Sometimes referred to as a "pure distribution." - -non-pure module distribution - a module distribution that contains at least one extension module. Sometimes - referred to as a "non-pure distribution." - -distribution root - the top-level directory of your source tree (or source distribution); the - directory where :file:`setup.py` exists. Generally :file:`setup.py` will be - run from this directory. diff --git a/Doc/distutils/packageindex.rst b/Doc/distutils/packageindex.rst deleted file mode 100644 index ccb9a598b2b7a2..00000000000000 --- a/Doc/distutils/packageindex.rst +++ /dev/null @@ -1,16 +0,0 @@ -:orphan: - -.. _package-index: - -******************************* -The Python Package Index (PyPI) -******************************* - -The `Python Package Index (PyPI)`_ stores metadata describing distributions -packaged with distutils and other publishing tools, as well the distribution -archives themselves. - -References to up to date PyPI documentation can be found at -:ref:`publishing-python-packages`. - -.. _Python Package Index (PyPI): https://pypi.org diff --git a/Doc/distutils/setupscript.rst b/Doc/distutils/setupscript.rst deleted file mode 100644 index 4386a60b664bfb..00000000000000 --- a/Doc/distutils/setupscript.rst +++ /dev/null @@ -1,713 +0,0 @@ -.. _setup-script: - -************************ -Writing the Setup Script -************************ - -.. include:: ./_setuptools_disclaimer.rst - -The setup script is the centre of all activity in building, distributing, and -installing modules using the Distutils. The main purpose of the setup script is -to describe your module distribution to the Distutils, so that the various -commands that operate on your modules do the right thing. As we saw in section -:ref:`distutils-simple-example` above, the setup script consists mainly of a call to -:func:`setup`, and most information supplied to the Distutils by the module -developer is supplied as keyword arguments to :func:`setup`. - -Here's a slightly more involved example, which we'll follow for the next couple -of sections: the Distutils' own setup script. (Keep in mind that although the -Distutils are included with Python 1.6 and later, they also have an independent -existence so that Python 1.5.2 users can use them to install other module -distributions. The Distutils' own setup script, shown here, is used to install -the package into Python 1.5.2.) :: - - #!/usr/bin/env python - - from distutils.core import setup - - setup(name='Distutils', - version='1.0', - description='Python Distribution Utilities', - author='Greg Ward', - author_email='gward@python.net', - url='https://www.python.org/sigs/distutils-sig/', - packages=['distutils', 'distutils.command'], - ) - -There are only two differences between this and the trivial one-file -distribution presented in section :ref:`distutils-simple-example`: more metadata, and the -specification of pure Python modules by package, rather than by module. This is -important since the Distutils consist of a couple of dozen modules split into -(so far) two packages; an explicit list of every module would be tedious to -generate and difficult to maintain. For more information on the additional -meta-data, see section :ref:`meta-data`. - -Note that any pathnames (files or directories) supplied in the setup script -should be written using the Unix convention, i.e. slash-separated. The -Distutils will take care of converting this platform-neutral representation into -whatever is appropriate on your current platform before actually using the -pathname. This makes your setup script portable across operating systems, which -of course is one of the major goals of the Distutils. In this spirit, all -pathnames in this document are slash-separated. - -This, of course, only applies to pathnames given to Distutils functions. If -you, for example, use standard Python functions such as :func:`glob.glob` or -:func:`os.listdir` to specify files, you should be careful to write portable -code instead of hardcoding path separators:: - - glob.glob(os.path.join('mydir', 'subdir', '*.html')) - os.listdir(os.path.join('mydir', 'subdir')) - - -.. _listing-packages: - -Listing whole packages -====================== - -The ``packages`` option tells the Distutils to process (build, distribute, -install, etc.) all pure Python modules found in each package mentioned in the -``packages`` list. In order to do this, of course, there has to be a -correspondence between package names and directories in the filesystem. The -default correspondence is the most obvious one, i.e. package :mod:`distutils` is -found in the directory :file:`distutils` relative to the distribution root. -Thus, when you say ``packages = ['foo']`` in your setup script, you are -promising that the Distutils will find a file :file:`foo/__init__.py` (which -might be spelled differently on your system, but you get the idea) relative to -the directory where your setup script lives. If you break this promise, the -Distutils will issue a warning but still process the broken package anyway. - -If you use a different convention to lay out your source directory, that's no -problem: you just have to supply the ``package_dir`` option to tell the -Distutils about your convention. For example, say you keep all Python source -under :file:`lib`, so that modules in the "root package" (i.e., not in any -package at all) are in :file:`lib`, modules in the :mod:`foo` package are in -:file:`lib/foo`, and so forth. Then you would put :: - - package_dir = {'': 'lib'} - -in your setup script. The keys to this dictionary are package names, and an -empty package name stands for the root package. The values are directory names -relative to your distribution root. In this case, when you say ``packages = -['foo']``, you are promising that the file :file:`lib/foo/__init__.py` exists. - -Another possible convention is to put the :mod:`foo` package right in -:file:`lib`, the :mod:`foo.bar` package in :file:`lib/bar`, etc. This would be -written in the setup script as :: - - package_dir = {'foo': 'lib'} - -A ``package: dir`` entry in the ``package_dir`` dictionary implicitly -applies to all packages below *package*, so the :mod:`foo.bar` case is -automatically handled here. In this example, having ``packages = ['foo', -'foo.bar']`` tells the Distutils to look for :file:`lib/__init__.py` and -:file:`lib/bar/__init__.py`. (Keep in mind that although ``package_dir`` -applies recursively, you must explicitly list all packages in -``packages``: the Distutils will *not* recursively scan your source tree -looking for any directory with an :file:`__init__.py` file.) - - -.. _listing-modules: - -Listing individual modules -========================== - -For a small module distribution, you might prefer to list all modules rather -than listing packages---especially the case of a single module that goes in the -"root package" (i.e., no package at all). This simplest case was shown in -section :ref:`distutils-simple-example`; here is a slightly more involved example:: - - py_modules = ['mod1', 'pkg.mod2'] - -This describes two modules, one of them in the "root" package, the other in the -:mod:`pkg` package. Again, the default package/directory layout implies that -these two modules can be found in :file:`mod1.py` and :file:`pkg/mod2.py`, and -that :file:`pkg/__init__.py` exists as well. And again, you can override the -package/directory correspondence using the ``package_dir`` option. - - -.. _describing-extensions: - -Describing extension modules -============================ - -Just as writing Python extension modules is a bit more complicated than writing -pure Python modules, describing them to the Distutils is a bit more complicated. -Unlike pure modules, it's not enough just to list modules or packages and expect -the Distutils to go out and find the right files; you have to specify the -extension name, source file(s), and any compile/link requirements (include -directories, libraries to link with, etc.). - -.. XXX read over this section - -All of this is done through another keyword argument to :func:`setup`, the -``ext_modules`` option. ``ext_modules`` is just a list of -:class:`~distutils.core.Extension` instances, each of which describes a -single extension module. -Suppose your distribution includes a single extension, called :mod:`foo` and -implemented by :file:`foo.c`. If no additional instructions to the -compiler/linker are needed, describing this extension is quite simple:: - - Extension('foo', ['foo.c']) - -The :class:`Extension` class can be imported from :mod:`distutils.core` along -with :func:`setup`. Thus, the setup script for a module distribution that -contains only this one extension and nothing else might be:: - - from distutils.core import setup, Extension - setup(name='foo', - version='1.0', - ext_modules=[Extension('foo', ['foo.c'])], - ) - -The :class:`Extension` class (actually, the underlying extension-building -machinery implemented by the :command:`build_ext` command) supports a great deal -of flexibility in describing Python extensions, which is explained in the -following sections. - - -Extension names and packages ----------------------------- - -The first argument to the :class:`~distutils.core.Extension` constructor is -always the name of the extension, including any package names. For example, :: - - Extension('foo', ['src/foo1.c', 'src/foo2.c']) - -describes an extension that lives in the root package, while :: - - Extension('pkg.foo', ['src/foo1.c', 'src/foo2.c']) - -describes the same extension in the :mod:`pkg` package. The source files and -resulting object code are identical in both cases; the only difference is where -in the filesystem (and therefore where in Python's namespace hierarchy) the -resulting extension lives. - -If you have a number of extensions all in the same package (or all under the -same base package), use the ``ext_package`` keyword argument to -:func:`setup`. For example, :: - - setup(..., - ext_package='pkg', - ext_modules=[Extension('foo', ['foo.c']), - Extension('subpkg.bar', ['bar.c'])], - ) - -will compile :file:`foo.c` to the extension :mod:`pkg.foo`, and :file:`bar.c` to -:mod:`pkg.subpkg.bar`. - - -Extension source files ----------------------- - -The second argument to the :class:`~distutils.core.Extension` constructor is -a list of source -files. Since the Distutils currently only support C, C++, and Objective-C -extensions, these are normally C/C++/Objective-C source files. (Be sure to use -appropriate extensions to distinguish C++ source files: :file:`.cc` and -:file:`.cpp` seem to be recognized by both Unix and Windows compilers.) - -However, you can also include SWIG interface (:file:`.i`) files in the list; the -:command:`build_ext` command knows how to deal with SWIG extensions: it will run -SWIG on the interface file and compile the resulting C/C++ file into your -extension. - -.. XXX SWIG support is rough around the edges and largely untested! - -This warning notwithstanding, options to SWIG can be currently passed like -this:: - - setup(..., - ext_modules=[Extension('_foo', ['foo.i'], - swig_opts=['-modern', '-I../include'])], - py_modules=['foo'], - ) - -Or on the commandline like this:: - - > python setup.py build_ext --swig-opts="-modern -I../include" - -On some platforms, you can include non-source files that are processed by the -compiler and included in your extension. Currently, this just means Windows -message text (:file:`.mc`) files and resource definition (:file:`.rc`) files for -Visual C++. These will be compiled to binary resource (:file:`.res`) files and -linked into the executable. - - -Preprocessor options --------------------- - -Three optional arguments to :class:`~distutils.core.Extension` will help if -you need to specify include directories to search or preprocessor macros to -define/undefine: ``include_dirs``, ``define_macros``, and ``undef_macros``. - -For example, if your extension requires header files in the :file:`include` -directory under your distribution root, use the ``include_dirs`` option:: - - Extension('foo', ['foo.c'], include_dirs=['include']) - -You can specify absolute directories there; if you know that your extension will -only be built on Unix systems with X11R6 installed to :file:`/usr`, you can get -away with :: - - Extension('foo', ['foo.c'], include_dirs=['/usr/include/X11']) - -You should avoid this sort of non-portable usage if you plan to distribute your -code: it's probably better to write C code like :: - - #include - -If you need to include header files from some other Python extension, you can -take advantage of the fact that header files are installed in a consistent way -by the Distutils :command:`install_headers` command. For example, the Numerical -Python header files are installed (on a standard Unix installation) to -:file:`/usr/local/include/python1.5/Numerical`. (The exact location will differ -according to your platform and Python installation.) Since the Python include -directory---\ :file:`/usr/local/include/python1.5` in this case---is always -included in the search path when building Python extensions, the best approach -is to write C code like :: - - #include - -If you must put the :file:`Numerical` include directory right into your header -search path, though, you can find that directory using the Distutils -:mod:`distutils.sysconfig` module:: - - from distutils.sysconfig import get_python_inc - incdir = os.path.join(get_python_inc(plat_specific=1), 'Numerical') - setup(..., - Extension(..., include_dirs=[incdir]), - ) - -Even though this is quite portable---it will work on any Python installation, -regardless of platform---it's probably easier to just write your C code in the -sensible way. - -You can define and undefine pre-processor macros with the ``define_macros`` and -``undef_macros`` options. ``define_macros`` takes a list of ``(name, value)`` -tuples, where ``name`` is the name of the macro to define (a string) and -``value`` is its value: either a string or ``None``. (Defining a macro ``FOO`` -to ``None`` is the equivalent of a bare ``#define FOO`` in your C source: with -most compilers, this sets ``FOO`` to the string ``1``.) ``undef_macros`` is -just a list of macros to undefine. - -For example:: - - Extension(..., - define_macros=[('NDEBUG', '1'), - ('HAVE_STRFTIME', None)], - undef_macros=['HAVE_FOO', 'HAVE_BAR']) - -is the equivalent of having this at the top of every C source file:: - - #define NDEBUG 1 - #define HAVE_STRFTIME - #undef HAVE_FOO - #undef HAVE_BAR - - -Library options ---------------- - -You can also specify the libraries to link against when building your extension, -and the directories to search for those libraries. The ``libraries`` option is -a list of libraries to link against, ``library_dirs`` is a list of directories -to search for libraries at link-time, and ``runtime_library_dirs`` is a list of -directories to search for shared (dynamically loaded) libraries at run-time. - -For example, if you need to link against libraries known to be in the standard -library search path on target systems :: - - Extension(..., - libraries=['gdbm', 'readline']) - -If you need to link with libraries in a non-standard location, you'll have to -include the location in ``library_dirs``:: - - Extension(..., - library_dirs=['/usr/X11R6/lib'], - libraries=['X11', 'Xt']) - -(Again, this sort of non-portable construct should be avoided if you intend to -distribute your code.) - -.. XXX Should mention clib libraries here or somewhere else! - - -Other options -------------- - -There are still some other options which can be used to handle special cases. - -The ``optional`` option is a boolean; if it is true, -a build failure in the extension will not abort the build process, but -instead simply not install the failing extension. - -The ``extra_objects`` option is a list of object files to be passed to the -linker. These files must not have extensions, as the default extension for the -compiler is used. - -``extra_compile_args`` and ``extra_link_args`` can be used to -specify additional command line options for the respective compiler and linker -command lines. - -``export_symbols`` is only useful on Windows. It can contain a list of -symbols (functions or variables) to be exported. This option is not needed when -building compiled extensions: Distutils will automatically add ``initmodule`` -to the list of exported symbols. - -The ``depends`` option is a list of files that the extension depends on -(for example header files). The build command will call the compiler on the -sources to rebuild extension if any on this files has been modified since the -previous build. - -Relationships between Distributions and Packages -================================================ - -A distribution may relate to packages in three specific ways: - -#. It can require packages or modules. - -#. It can provide packages or modules. - -#. It can obsolete packages or modules. - -These relationships can be specified using keyword arguments to the -:func:`distutils.core.setup` function. - -Dependencies on other Python modules and packages can be specified by supplying -the *requires* keyword argument to :func:`setup`. The value must be a list of -strings. Each string specifies a package that is required, and optionally what -versions are sufficient. - -To specify that any version of a module or package is required, the string -should consist entirely of the module or package name. Examples include -``'mymodule'`` and ``'xml.parsers.expat'``. - -If specific versions are required, a sequence of qualifiers can be supplied in -parentheses. Each qualifier may consist of a comparison operator and a version -number. The accepted comparison operators are:: - - < > == - <= >= != - -These can be combined by using multiple qualifiers separated by commas (and -optional whitespace). In this case, all of the qualifiers must be matched; a -logical AND is used to combine the evaluations. - -Let's look at a bunch of examples: - -+-------------------------+----------------------------------------------+ -| Requires Expression | Explanation | -+=========================+==============================================+ -| ``==1.0`` | Only version ``1.0`` is compatible | -+-------------------------+----------------------------------------------+ -| ``>1.0, !=1.5.1, <2.0`` | Any version after ``1.0`` and before ``2.0`` | -| | is compatible, except ``1.5.1`` | -+-------------------------+----------------------------------------------+ - -Now that we can specify dependencies, we also need to be able to specify what we -provide that other distributions can require. This is done using the *provides* -keyword argument to :func:`setup`. The value for this keyword is a list of -strings, each of which names a Python module or package, and optionally -identifies the version. If the version is not specified, it is assumed to match -that of the distribution. - -Some examples: - -+---------------------+----------------------------------------------+ -| Provides Expression | Explanation | -+=====================+==============================================+ -| ``mypkg`` | Provide ``mypkg``, using the distribution | -| | version | -+---------------------+----------------------------------------------+ -| ``mypkg (1.1)`` | Provide ``mypkg`` version 1.1, regardless of | -| | the distribution version | -+---------------------+----------------------------------------------+ - -A package can declare that it obsoletes other packages using the *obsoletes* -keyword argument. The value for this is similar to that of the *requires* -keyword: a list of strings giving module or package specifiers. Each specifier -consists of a module or package name optionally followed by one or more version -qualifiers. Version qualifiers are given in parentheses after the module or -package name. - -The versions identified by the qualifiers are those that are obsoleted by the -distribution being described. If no qualifiers are given, all versions of the -named module or package are understood to be obsoleted. - -.. _distutils-installing-scripts: - -Installing Scripts -================== - -So far we have been dealing with pure and non-pure Python modules, which are -usually not run by themselves but imported by scripts. - -Scripts are files containing Python source code, intended to be started from the -command line. Scripts don't require Distutils to do anything very complicated. -The only clever feature is that if the first line of the script starts with -``#!`` and contains the word "python", the Distutils will adjust the first line -to refer to the current interpreter location. By default, it is replaced with -the current interpreter location. The :option:`!--executable` (or :option:`!-e`) -option will allow the interpreter path to be explicitly overridden. - -The ``scripts`` option simply is a list of files to be handled in this -way. From the PyXML setup script:: - - setup(..., - scripts=['scripts/xmlproc_parse', 'scripts/xmlproc_val'] - ) - -.. versionchanged:: 3.1 - All the scripts will also be added to the ``MANIFEST`` file if no template is - provided. See :ref:`manifest`. - - -.. _distutils-installing-package-data: - -Installing Package Data -======================= - -Often, additional files need to be installed into a package. These files are -often data that's closely related to the package's implementation, or text files -containing documentation that might be of interest to programmers using the -package. These files are called :dfn:`package data`. - -Package data can be added to packages using the ``package_data`` keyword -argument to the :func:`setup` function. The value must be a mapping from -package name to a list of relative path names that should be copied into the -package. The paths are interpreted as relative to the directory containing the -package (information from the ``package_dir`` mapping is used if appropriate); -that is, the files are expected to be part of the package in the source -directories. They may contain glob patterns as well. - -The path names may contain directory portions; any necessary directories will be -created in the installation. - -For example, if a package should contain a subdirectory with several data files, -the files can be arranged like this in the source tree:: - - setup.py - src/ - mypkg/ - __init__.py - module.py - data/ - tables.dat - spoons.dat - forks.dat - -The corresponding call to :func:`setup` might be:: - - setup(..., - packages=['mypkg'], - package_dir={'mypkg': 'src/mypkg'}, - package_data={'mypkg': ['data/*.dat']}, - ) - - -.. versionchanged:: 3.1 - All the files that match ``package_data`` will be added to the ``MANIFEST`` - file if no template is provided. See :ref:`manifest`. - - -.. _distutils-additional-files: - -Installing Additional Files -=========================== - -The ``data_files`` option can be used to specify additional files needed -by the module distribution: configuration files, message catalogs, data files, -anything which doesn't fit in the previous categories. - -``data_files`` specifies a sequence of (*directory*, *files*) pairs in the -following way:: - - setup(..., - data_files=[('bitmaps', ['bm/b1.gif', 'bm/b2.gif']), - ('config', ['cfg/data.cfg'])], - ) - -Each (*directory*, *files*) pair in the sequence specifies the installation -directory and the files to install there. - -Each file name in *files* is interpreted relative to the :file:`setup.py` -script at the top of the package source distribution. Note that you can -specify the directory where the data files will be installed, but you cannot -rename the data files themselves. - -The *directory* should be a relative path. It is interpreted relative to the -installation prefix (Python's ``sys.prefix`` for system installations; -``site.USER_BASE`` for user installations). Distutils allows *directory* to be -an absolute installation path, but this is discouraged since it is -incompatible with the wheel packaging format. No directory information from -*files* is used to determine the final location of the installed file; only -the name of the file is used. - -You can specify the ``data_files`` options as a simple sequence of files -without specifying a target directory, but this is not recommended, and the -:command:`install` command will print a warning in this case. To install data -files directly in the target directory, an empty string should be given as the -directory. - -.. versionchanged:: 3.1 - All the files that match ``data_files`` will be added to the ``MANIFEST`` - file if no template is provided. See :ref:`manifest`. - - -.. _meta-data: - -Additional meta-data -==================== - -The setup script may include additional meta-data beyond the name and version. -This information includes: - -+----------------------+---------------------------+-----------------+--------+ -| Meta-Data | Description | Value | Notes | -+======================+===========================+=================+========+ -| ``name`` | name of the package | short string | \(1) | -+----------------------+---------------------------+-----------------+--------+ -| ``version`` | version of this release | short string | (1)(2) | -+----------------------+---------------------------+-----------------+--------+ -| ``author`` | package author's name | short string | \(3) | -+----------------------+---------------------------+-----------------+--------+ -| ``author_email`` | email address of the | email address | \(3) | -| | package author | | | -+----------------------+---------------------------+-----------------+--------+ -| ``maintainer`` | package maintainer's name | short string | \(3) | -+----------------------+---------------------------+-----------------+--------+ -| ``maintainer_email`` | email address of the | email address | \(3) | -| | package maintainer | | | -+----------------------+---------------------------+-----------------+--------+ -| ``url`` | home page for the package | URL | \(1) | -+----------------------+---------------------------+-----------------+--------+ -| ``description`` | short, summary | short string | | -| | description of the | | | -| | package | | | -+----------------------+---------------------------+-----------------+--------+ -| ``long_description`` | longer description of the | long string | \(4) | -| | package | | | -+----------------------+---------------------------+-----------------+--------+ -| ``download_url`` | location where the | URL | | -| | package may be downloaded | | | -+----------------------+---------------------------+-----------------+--------+ -| ``classifiers`` | a list of classifiers | list of strings | (6)(7) | -+----------------------+---------------------------+-----------------+--------+ -| ``platforms`` | a list of platforms | list of strings | (6)(8) | -+----------------------+---------------------------+-----------------+--------+ -| ``keywords`` | a list of keywords | list of strings | (6)(8) | -+----------------------+---------------------------+-----------------+--------+ -| ``license`` | license for the package | short string | \(5) | -+----------------------+---------------------------+-----------------+--------+ - -Notes: - -(1) - These fields are required. - -(2) - It is recommended that versions take the form *major.minor[.patch[.sub]]*. - -(3) - Either the author or the maintainer must be identified.

The patch number -increments when bug-fix releases are made. Additional trailing version -information is sometimes used to indicate sub-releases. These are -"a1,a2,...,aN" (for alpha releases, where functionality and API may change), -"b1,b2,...,bN" (for beta releases, which only fix bugs) and "pr1,pr2,...,prN" -(for final pre-release release testing).

It contains +configuration (e.g. the import path) and runtime state (e.g. the set of +imported modules). + +Python supports running multiple interpreters in one process. There are +two cases to think about—users may run interpreters: + +- in sequence, with several :c:func:`Py_InitializeEx`/:c:func:`Py_FinalizeEx` + cycles, and +- in parallel, managing "sub-interpreters" using + :c:func:`Py_NewInterpreter`/:c:func:`Py_EndInterpreter`. + +Both cases (and combinations of them) would be most useful when +embedding Python within a library. Libraries generally shouldn't make +assumptions about the application that uses them, which include +assuming a process-wide "main Python interpreter". + +Historically, Python extension modules don't handle this use case well. +Many extension modules (and even some stdlib modules) use *per-process* +global state, because C ``static`` variables are extremely easy to use. +Thus, data that should be specific to an interpreter ends up being shared +between interpreters. Unless the extension developer is careful, it is very +easy to introduce edge cases that lead to crashes when a module is loaded in +more than one interpreter in the same process. + +Unfortunately, *per-interpreter* state is not easy to achieve. Extension +authors tend to not keep multiple interpreters in mind when developing, +and it is currently cumbersome to test the behavior. + +Enter Per-Module State +---------------------- + +Instead of focusing on per-interpreter state, Python's C API is evolving +to better support the more granular *per-module* state. +This means that C-level data is be attached to a *module object*. +Each interpreter creates its own module object, keeping the data separate. +For testing the isolation, multiple module objects corresponding to a single +extension can even be loaded in a single interpreter. + +Per-module state provides an easy way to think about lifetime and +resource ownership: the extension module will initialize when a +module object is created, and clean up when it's freed. In this regard, +a module is just like any other :c:expr:`PyObject *`; there are no "on +interpreter shutdown" hooks to think—or forget—about. + +Note that there are use cases for different kinds of "globals": +per-process, per-interpreter, per-thread or per-task state. +With per-module state as the default, these are still possible, +but you should treat them as exceptional cases: +if you need them, you should give them additional care and testing. +(Note that this guide does not cover them.) + + +Isolated Module Objects +----------------------- + +The key point to keep in mind when developing an extension module is +that several module objects can be created from a single shared library. +For example: + +.. code-block:: pycon + + >>> import sys + >>> import binascii + >>> old_binascii = binascii + >>> del sys.modules['binascii'] + >>> import binascii # create a new module object + >>> old_binascii == binascii + False + +As a rule of thumb, the two modules should be completely independent. +All objects and state specific to the module should be encapsulated +within the module object, not shared with other module objects, and +cleaned up when the module object is deallocated. +Since this just is a rule of thumb, exceptions are possible +(see `Managing Global State`_), but they will need more +thought and attention to edge cases. + +While some modules could do with less stringent restrictions, isolated +modules make it easier to set clear expectations and guidelines that +work across a variety of use cases. + + +Surprising Edge Cases +--------------------- + +Note that isolated modules do create some surprising edge cases. Most +notably, each module object will typically not share its classes and +exceptions with other similar modules. Continuing from the +`example above `__, +note that ``old_binascii.Error`` and ``binascii.Error`` are +separate objects. In the following code, the exception is *not* caught: + +.. code-block:: pycon + + >>> old_binascii.Error == binascii.Error + False + >>> try: + ... old_binascii.unhexlify(b'qwertyuiop') + ... except binascii.Error: + ... print('boo') + ... + Traceback (most recent call last): + File "", line 2, in + binascii.Error: Non-hexadecimal digit found + +This is expected. Notice that pure-Python modules behave the same way: +it is a part of how Python works. + +The goal is to make extension modules safe at the C level, not to make +hacks behave intuitively. Mutating ``sys.modules`` "manually" counts +as a hack. + + +Making Modules Safe with Multiple Interpreters +============================================== + + +Managing Global State +--------------------- + +Sometimes, the state associated with a Python module is not specific to that module, but +to the entire process (or something else "more global" than a module). +For example: + +- The ``readline`` module manages *the* terminal. +- A module running on a circuit board wants to control *the* on-board + LED. + +In these cases, the Python module should provide *access* to the global +state, rather than *own* it. If possible, write the module so that +multiple copies of it can access the state independently (along with +other libraries, whether for Python or other languages). If that is not +possible, consider explicit locking. + +If it is necessary to use process-global state, the simplest way to +avoid issues with multiple interpreters is to explicitly prevent a +module from being loaded more than once per process—see +`Opt-Out: Limiting to One Module Object per Process`_. + + +Managing Per-Module State +------------------------- + +To use per-module state, use +:ref:`multi-phase extension module initialization `. +This signals that your module supports multiple interpreters correctly. + +Set ``PyModuleDef.m_size`` to a positive number to request that many +bytes of storage local to the module. Usually, this will be set to the +size of some module-specific ``struct``, which can store all of the +module's C-level state. In particular, it is where you should put +pointers to classes (including exceptions, but excluding static types) +and settings (e.g. ``csv``'s :py:data:`~csv.field_size_limit`) +which the C code needs to function. + +.. note:: + Another option is to store state in the module's ``__dict__``, + but you must avoid crashing when users modify ``__dict__`` from + Python code. This usually means error- and type-checking at the C level, + which is easy to get wrong and hard to test sufficiently. + + However, if module state is not needed in C code, storing it in + ``__dict__`` only is a good idea. + +If the module state includes ``PyObject`` pointers, the module object +must hold references to those objects and implement the module-level hooks +``m_traverse``, ``m_clear`` and ``m_free``. These work like +``tp_traverse``, ``tp_clear`` and ``tp_free`` of a class.

If this is not yet the case for your +module, you can explicitly make your module loadable only once per +process. For example:: + + static int loaded = 0; + + static int + exec_module(PyObject* module) + { + if (loaded) { + PyErr_SetString(PyExc_ImportError, + "cannot load module more than once per process"); + return -1; + } + loaded = 1; + // ... rest of initialization + } + + +Module State Access from Functions +---------------------------------- + +Accessing the state from module-level functions is straightforward. +Functions get the module object as their first argument; for extracting +the state, you can use ``PyModule_GetState``:: + + static PyObject * + func(PyObject *module, PyObject *args) + { + my_struct *state = (my_struct*)PyModule_GetState(module); + if (state == NULL) { + return NULL; + } + // ... rest of logic + } + +.. note:: + ``PyModule_GetState`` may return ``NULL`` without setting an + exception if there is no module state, i.e. ``PyModuleDef.m_size`` was + zero. In your own module, you're in control of ``m_size``, so this is + easy to prevent. + + +Heap Types +========== + +Traditionally, types defined in C code are *static*; that is, +``static PyTypeObject`` structures defined directly in code and +initialized using ``PyType_Ready()``. + +Such types are necessarily shared across the process. Sharing them +between module objects requires paying attention to any state they own +or access. To limit the possible issues, static types are immutable at +the Python level: for example, you can't set ``str.myattribute = 123``. + +.. impl-detail:: + Sharing truly immutable objects between interpreters is fine, + as long as they don't provide access to mutable objects. + However, in CPython, every Python object has a mutable implementation + detail: the reference count. Changes to the refcount are guarded by the GIL. + Thus, code that shares any Python objects across interpreters implicitly + depends on CPython's current, process-wide GIL. + +Because they are immutable and process-global, static types cannot access +"their" module state. +If any method of such a type requires access to module state, +the type must be converted to a *heap-allocated type*, or *heap type* +for short. These correspond more closely to classes created by Python's +``class`` statement. + +For new modules, using heap types by default is a good rule of thumb. + + +Changing Static Types to Heap Types +----------------------------------- + +Static types can be converted to heap types, but note that +the heap type API was not designed for "lossless" conversion +from static types—that is, creating a type that works exactly like a given +static type. +So, when rewriting the class definition in a new API, +you are likely to unintentionally change a few details (e.g. pickleability +or inherited slots). +Always test the details that are important to you. + +Watch out for the following two points in particular (but note that this is not +a comprehensive list): + +* Unlike static types, heap type objects are mutable by default. + Use the :c:data:`Py_TPFLAGS_IMMUTABLETYPE` flag to prevent mutability. +* Heap types inherit :c:member:`~PyTypeObject.tp_new` by default, + so it may become possible to instantiate them from Python code. + You can prevent this with the :c:data:`Py_TPFLAGS_DISALLOW_INSTANTIATION` flag. + + +Defining Heap Types +------------------- + +Heap types can be created by filling a :c:struct:`PyType_Spec` structure, a +description or "blueprint" of a class, and calling +:c:func:`PyType_FromModuleAndSpec` to construct a new class object. + +.. note:: + Other functions, like :c:func:`PyType_FromSpec`, can also create + heap types, but :c:func:`PyType_FromModuleAndSpec` associates the module + with the class, allowing access to the module state from methods. + +The class should generally be stored in *both* the module state (for +safe access from C) and the module's ``__dict__`` (for access from +Python code). + + +Garbage-Collection Protocol +--------------------------- + +Instances of heap types hold a reference to their type. +This ensures that the type isn't destroyed before all its instances are, +but may result in reference cycles that need to be broken by the +garbage collector. + +To avoid memory leaks, instances of heap types must implement the +garbage collection protocol. +That is, heap types should: + +- Have the :c:data:`Py_TPFLAGS_HAVE_GC` flag. +- Define a traverse function using ``Py_tp_traverse``, which + visits the type (e.g. using :c:expr:`Py_VISIT(Py_TYPE(self))`). + +Please refer to the :ref:`the documentation ` of +:c:data:`Py_TPFLAGS_HAVE_GC` and :c:member:`~PyTypeObject.tp_traverse` +for additional considerations. + +If your traverse function delegates to the ``tp_traverse`` of its base class +(or another type), ensure that ``Py_TYPE(self)`` is visited only once. +Note that only heap type are expected to visit the type in ``tp_traverse``. + +For example, if your traverse function includes:: + + base->tp_traverse(self, visit, arg) + +...and ``base`` may be a static type, then it should also include:: + + if (base->tp_flags & Py_TPFLAGS_HEAPTYPE) { + // a heap type's tp_traverse already visited Py_TYPE(self) + } else { + Py_VISIT(Py_TYPE(self)); + } + +It is not necessary to handle the type's reference count in ``tp_new`` +and ``tp_clear``. + + +Module State Access from Classes +-------------------------------- + +If you have a type object defined with :c:func:`PyType_FromModuleAndSpec`, +you can call :c:func:`PyType_GetModule` to get the associated module, and then +:c:func:`PyModule_GetState` to get the module's state. + +To save a some tedious error-handling boilerplate code, you can combine +these two steps with :c:func:`PyType_GetModuleState`, resulting in:: + + my_struct *state = (my_struct*)PyType_GetModuleState(type); + if (state === NULL) { + return NULL; + } + + +Module State Access from Regular Methods +---------------------------------------- + +Accessing the module-level state from methods of a class is somewhat more +complicated, but is possible thanks to API introduced in Python 3.9. +To get the state, you need to first get the *defining class*, and then +get the module state from it. + +The largest roadblock is getting *the class a method was defined in*, or +that method's "defining class" for short. The defining class can have a +reference to the module it is part of. + +Do not confuse the defining class with :c:expr:`Py_TYPE(self)`. If the method +is called on a *subclass* of your type, ``Py_TYPE(self)`` will refer to +that subclass, which may be defined in different module than yours. + +.. note:: + The following Python code can illustrate the concept. + ``Base.get_defining_class`` returns ``Base`` even + if ``type(self) == Sub``: + + .. code-block:: python + + class Base: + def get_type_of_self(self): + return type(self) + + def get_defining_class(self): + return __class__ + + class Sub(Base): + pass + +For a method to get its "defining class", it must use the +:data:`METH_METHOD | METH_FASTCALL | METH_KEYWORDS` +:c:type:`calling convention ` +and the corresponding :c:type:`PyCMethod` signature:: + + PyObject *PyCMethod( + PyObject *self, // object the method was called on + PyTypeObject *defining_class, // defining class + PyObject *const *args, // C array of arguments + Py_ssize_t nargs, // length of "args" + PyObject *kwnames) // NULL, or dict of keyword arguments + +Once you have the defining class, call :c:func:`PyType_GetModuleState` to get +the state of its associated module. + +For example:: + + static PyObject * + example_method(PyObject *self, + PyTypeObject *defining_class, + PyObject *const *args, + Py_ssize_t nargs, + PyObject *kwnames) + { + my_struct *state = (my_struct*)PyType_GetModuleState(defining_class); + if (state === NULL) { + return NULL; + } + ... // rest of logic + } + + PyDoc_STRVAR(example_method_doc, "..."); + + static PyMethodDef my_methods[] = { + {"example_method", + (PyCFunction)(void(*)(void))example_method, + METH_METHOD|METH_FASTCALL|METH_KEYWORDS, + example_method_doc} + {NULL}, + } + + +Module State Access from Slot Methods, Getters and Setters +---------------------------------------------------------- + +.. note:: + + This is new in Python 3.11. + + ..

However, it will always + return a module with the same definition, ensuring a compatible + C memory layout. + + +Lifetime of the Module State +---------------------------- + +When a module object is garbage-collected, its module state is freed. +For each pointer to (a part of) the module state, you must hold a reference +to the module object. + +Usually this is not an issue, because types created with +:c:func:`PyType_FromModuleAndSpec`, and their instances, hold a reference +to the module. +However, you must be careful in reference counting when you reference +module state from other places, such as callbacks for external +libraries. + + +Open Issues +=========== + +Several issues around per-module state and heap types are still open. + +Discussions about improving the situation are best held on the `capi-sig +mailing list `__. + + +Per-Class Scope +--------------- + +It is currently (as of Python 3.11) not possible to attach state to individual +*types* without relying on CPython implementation details (which may change +in the future—perhaps, ironically, to allow a proper solution for +per-class scope). + + +Lossless Conversion to Heap Types +--------------------------------- + +The heap type API was not designed for "lossless" conversion from static types; +that is, creating a type that works exactly like a given static type. diff --git a/Doc/howto/logging-cookbook.rst b/Doc/howto/logging-cookbook.rst index 79b4069f035076..1a0afb6940dab9 100644 --- a/Doc/howto/logging-cookbook.rst +++ b/Doc/howto/logging-cookbook.rst @@ -219,7 +219,7 @@ messages should not.

Before that, -there was no :func:`sorted` builtin and :meth:`list.sort` took no keyword -arguments. Instead, all of the Py2.x versions supported a *cmp* parameter to -handle user specified comparison functions. - -In Py3.0, the *cmp* parameter was removed entirely (as part of a larger effort to -simplify and unify the language, eliminating the conflict between rich -comparisons and the :meth:`__cmp__` magic method). - -In Py2.x, sort allowed an optional function which can be called for doing the -comparisons. That function should take two arguments to be compared and then -return a negative value for less-than, return zero if they are equal, or return -a positive value for greater-than. For example, we can do: - -.. doctest:: - - >>> def numeric_compare(x, y): - ... return x - y - >>> sorted([5, 2, 4, 1, 3], cmp=numeric_compare) # doctest: +SKIP - [1, 2, 3, 4, 5] - -Or you can reverse the order of comparison with: - -.. doctest:: - - >>> def reverse_numeric(x, y): - ... return y - x - >>> sorted([5, 2, 4, 1, 3], cmp=reverse_numeric) # doctest: +SKIP - [5, 4, 3, 2, 1] - -When porting code from Python 2.x to 3.x, the situation can arise when you have -the user supplying a comparison function and you need to convert that to a key -function. The following wrapper makes that easy to do: - -.. testcode:: - - def cmp_to_key(mycmp): - 'Convert a cmp= function into a key= function' - class K: - def __init__(self, obj, *args): - self.obj = obj - def __lt__(self, other): - return mycmp(self.obj, other.obj) < 0 - def __gt__(self, other): - return mycmp(self.obj, other.obj) > 0 - def __eq__(self, other): - return mycmp(self.obj, other.obj) == 0 - def __le__(self, other): - return mycmp(self.obj, other.obj) <= 0 - def __ge__(self, other): - return mycmp(self.obj, other.obj) >= 0 - def __ne__(self, other): - return mycmp(self.obj, other.obj) != 0 - return K - -.. doctest:: - :hide: +Unlike key functions that return an absolute value for sorting, a comparison +function computes the relative ordering for two inputs. - >>> sorted([5, 2, 4, 1, 3], key=cmp_to_key(reverse_numeric)) - [5, 4, 3, 2, 1] +For example, a `balance scale +`_ +compares two samples giving a relative ordering: lighter, equal, or heavier. +Likewise, a comparison function such as ``cmp(a, b)`` will return a negative +value for less-than, zero if the inputs are equal, or a positive value for +greater-than. -To convert to a key function, just wrap the old comparison function: - -.. testsetup:: - - from functools import cmp_to_key - -.. doctest:: +It is common to encounter comparison functions when translating algorithms from +other languages. Also, some libraries provide comparison functions as part of +their API. For example, :func:`locale.strcoll` is a comparison function. - >>> sorted([5, 2, 4, 1, 3], key=cmp_to_key(reverse_numeric)) - [5, 4, 3, 2, 1] +To accommodate those situations, Python provides +:class:`functools.cmp_to_key` to wrap the comparison function +to make it usable as a key function:: -In Python 3.2, the :func:`functools.cmp_to_key` function was added to the -:mod:`functools` module in the standard library. + sorted(words, key=cmp_to_key(strcoll)) # locale-aware sort order Odds and Ends ============= * For locale aware sorting, use :func:`locale.strxfrm` for a key function or - :func:`locale.strcoll` for a comparison function. + :func:`locale.strcoll` for a comparison function. This is necessary + because "alphabetical" sort orderings can vary across cultures even + if the underlying alphabet is the same. * The *reverse* parameter still maintains sort stability (so that records with equal keys retain the original order).

For an index i, usedpools[i+i] is the header for a list of +all partially used pools holding small blocks with "size class idx" i. So +usedpools[0] corresponds to blocks of size 8, usedpools[2] to blocks of size +16, and so on: index 2*i <-> blocks of size (i+1)<freeblock points to +the start of a singly-linked list of free blocks within the pool. When a +block is freed, it's inserted at the front of its pool's freeblock list. Note +that the available blocks in a pool are *not* linked all together when a pool +is initialized. Instead only "the first two" (lowest addresses) blocks are +set up, returning the first such block, and setting pool->freeblock to a +one-block list holding the second such block. This is consistent with that +pymalloc strives at all levels (arena, pool, and block) never to touch a piece +of memory until it's actually needed. + +So long as a pool is in the used state, we're certain there *is* a block +available for allocating, and pool->freeblock is not NULL. If pool->freeblock +points to the end of the free list before we've carved the entire pool into +blocks, that means we simply haven't yet gotten to one of the higher-address +blocks. The offset from the pool_header to the start of "the next" virgin +block is stored in the pool_header nextoffset member, and the largest value +of nextoffset that makes sense is stored in the maxnextoffset member when a +pool is initialized. All the blocks in a pool have been passed out at least +once when and only when nextoffset > maxnextoffset. + + +Major obscurity: While the usedpools vector is declared to have poolp +entries, it doesn't really. It really contains two pointers per (conceptual) +poolp entry, the nextpool and prevpool members of a pool_header. The +excruciating initialization code below fools C so that + + usedpool[i+i] + +"acts like" a genuine poolp, but only so long as you only reference its +nextpool and prevpool members. The "- 2*sizeof(pymem_block *)" gibberish is +compensating for that a pool_header's nextpool and prevpool members +immediately follow a pool_header's first two members: + + union { pymem_block *_padding; + uint count; } ref; + pymem_block *freeblock; + +each of which consume sizeof(pymem_block *) bytes. So what usedpools[i+i] really +contains is a fudged-up pointer p such that *if* C believes it's a poolp +pointer, then p->nextpool and p->prevpool are both p (meaning that the headed +circular list is empty). + +It's unclear why the usedpools setup is so convoluted. It could be to +minimize the amount of cache required to hold this heavily-referenced table +(which only *needs* the two interpool pointer members of a pool_header). OTOH, +referencing code has to remember to "double the index" and doing so isn't +free, usedpools[0] isn't a strictly legal pointer, and we're crucially relying +on that C doesn't insert any padding anywhere in a pool_header at or before +the prevpool member. +**************************************************************************** */ + +#define OBMALLOC_USED_POOLS_SIZE (2 * ((NB_SMALL_SIZE_CLASSES + 7) / 8) * 8) + +struct _obmalloc_pools { + poolp used[OBMALLOC_USED_POOLS_SIZE]; +}; + + +/*========================================================================== +Arena management. + +`arenas` is a vector of arena_objects.

For software that doesn't find -the library on its own, you must add a '-ldl' to the appropriate -Makefile (or environment) variable, usually LIBS. - -If you installed dlcompat into a directory other than /usr/local/lib, -you must tell the compiler where to find it. Add '-L/lib' to -LDFLAGS (or CFLAGS) and '-I/include' to CPPFLAGS (or CFLAGS). - -Notes ------ -If you are writing new software and plan to have Mac OX X compatibility you -should look at the dyld api's in /usr/include/mach-o/dyld.h, rather than -using dlcompat, using the native api's is the supported method of loading -dynamically on Mac OS X, if you want an small example, look at dlfcn_simple.c, -which should help get you started. - -Also note that the functions in dlcompat are not thread safe, and while it is not -POSIX spec compliant, it is about as close to compliance as it is going to get though. - -You can always get the latest version from opendarwin cvs: - - cvs -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od login - cvs -z3 -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od \ - co -d dlcompat proj/dlcompat - - -It is hoped that this library will be useful, and as bug free as possible, if you find -any bugs please let us know about them so they can be fixed. - -Please send bug reports to Peter O'Gorman - -Thanks. - diff --git a/Modules/_ctypes/darwin/README.ctypes b/Modules/_ctypes/darwin/README.ctypes deleted file mode 100644 index 8520b01f49da1d..00000000000000 --- a/Modules/_ctypes/darwin/README.ctypes +++ /dev/null @@ -1,11 +0,0 @@ -The files in this directory are taken from -http://www.opendarwin.org/cgi-bin/cvsweb.cgi/~checkout~/proj/dlcompat/ - -The LICENSE in this directory applies to these files. - -Thomas Heller, Jan 2003 - -These files have been modified so they fall back to the system -dlfcn calls if available in libSystem. - -Bob Ippolito, Feb 2006 diff --git a/Modules/_ctypes/darwin/dlfcn.h b/Modules/_ctypes/darwin/dlfcn.h deleted file mode 100644 index a2afc3eeb84794..00000000000000 --- a/Modules/_ctypes/darwin/dlfcn.h +++ /dev/null @@ -1,84 +0,0 @@ -/* -Copyright (c) 2002 Jorge Acereda & - Peter O'Gorman - -Portions may be copyright others, see the AUTHORS file included with this -distribution. - -Maintained by Peter O'Gorman - -Bug Reports and other queries should go to - -Permission is hereby granted, free of charge, to any person obtaining -a copy of this software and associated documentation files (the -"Software"), to deal in the Software without restriction, including -without limitation the rights to use, copy, modify, merge, publish, -distribute, sublicense, and/or sell copies of the Software, and to -permit persons to whom the Software is furnished to do so, subject to -the following conditions: - -The above copyright notice and this permission notice shall be -included in all copies or substantial portions of the Software. - -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, -EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND -NONINFRINGEMENT.

This is a development snapshot! - -libffi-1.20 was released on October 5, 1998. Check the libffi web -page for updates: . - - -What is libffi? -=============== - -Compilers for high level languages generate code that follow certain -conventions. These conventions are necessary, in part, for separate -compilation to work. One such convention is the "calling -convention". The "calling convention" is essentially a set of -assumptions made by the compiler about where function arguments will -be found on entry to a function. A "calling convention" also specifies -where the return value for a function is found. - -Some programs may not know at the time of compilation what arguments -are to be passed to a function. For instance, an interpreter may be -told at run-time about the number and types of arguments used to call -a given function. Libffi can be used in such programs to provide a -bridge from the interpreter program to compiled code. - -The libffi library provides a portable, high level programming -interface to various calling conventions. This allows a programmer to -call any function specified by a call interface description at run -time. - -Ffi stands for Foreign Function Interface. A foreign function -interface is the popular name for the interface that allows code -written in one language to call code written in another language. The -libffi library really only provides the lowest, machine dependent -layer of a fully featured foreign function interface. A layer must -exist above libffi that handles type conversions for values passed -between the two languages. - - -Supported Platforms and Prerequisites -===================================== - -Libffi has been ported to: - - SunOS 4.1.3 & Solaris 2.x (SPARC-V8, SPARC-V9) - - Irix 5.3 & 6.2 (System V/o32 & n32) - - Intel x86 - Linux (System V ABI) - - Alpha - Linux and OSF/1 - - m68k - Linux (System V ABI) - - PowerPC - Linux (System V ABI, Darwin, AIX) - - ARM - Linux (System V ABI) - -Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are -that other versions will work. Libffi has also been built and tested -with the SGI compiler tools. - -On PowerPC, the tests failed (see the note below). - -You must use GNU make to build libffi. SGI's make will not work. -Sun's probably won't either. - -If you port libffi to another platform, please let me know! I assume -that some will be easy (x86 NetBSD), and others will be more difficult -(HP). - - -Installing libffi -================= - -[Note: before actually performing any of these installation steps, - you may wish to read the "Platform Specific Notes" below.] - -First you must configure the distribution for your particular -system. Go to the directory you wish to build libffi in and run the -"configure" program found in the root directory of the libffi source -distribution. - -You may want to tell configure where to install the libffi library and -header files. To do that, use the --prefix configure switch. Libffi -will install under /usr/local by default. - -If you want to enable extra run-time debugging checks use the the ---enable-debug configure switch. This is useful when your program dies -mysteriously while using libffi. - -Another useful configure switch is --enable-purify-safety. Using this -will add some extra code which will suppress certain warnings when you -are using Purify with libffi. Only use this switch when using -Purify, as it will slow down the library. - -Configure has many other options. Use "configure --help" to see them all. - -Once configure has finished, type "make". Note that you must be using -GNU make. SGI's make will not work. Sun's probably won't either. -You can ftp GNU make from prep.ai.mit.edu:/pub/gnu. - -To ensure that libffi is working as advertised, type "make test". - -To install the library and header files, type "make install". - - -Using libffi -============ - - The Basics - ---------- - -Libffi assumes that you have a pointer to the function you wish to -call and that you know the number and types of arguments to pass it, -as well as the return type of the function. - -The first thing you must do is create an ffi_cif object that matches -the signature of the function you wish to call. The cif in ffi_cif -stands for Call InterFace. To prepare a call interface object, use the -following function: - -ffi_status ffi_prep_cif(ffi_cif *cif, ffi_abi abi, - unsigned int nargs, - ffi_type *rtype, ffi_type **atypes); - - CIF is a pointer to the call interface object you wish - to initialize. - - ABI is an enum that specifies the calling convention - to use for the call. FFI_DEFAULT_ABI defaults - to the system's native calling convention. Other - ABI's may be used with care. They are system - specific. - - NARGS is the number of arguments this function accepts. - libffi does not yet support vararg functions. - - RTYPE is a pointer to an ffi_type structure that represents - the return type of the function. Ffi_type objects - describe the types of values. libffi provides - ffi_type objects for many of the native C types: - signed int, unsigned int, signed char, unsigned char, - etc. There is also a pointer ffi_type object and - a void ffi_type. Use &ffi_type_void for functions that - don't return values. - - ATYPES is a vector of ffi_type pointers. ARGS must be NARGS long. - If NARGS is 0, this is ignored. - - -ffi_prep_cif will return a status code that you are responsible -for checking. It will be one of the following: - - FFI_OK - All is good. - - FFI_BAD_TYPEDEF - One of the ffi_type objects that ffi_prep_cif - came across is bad. - - -Before making the call, the VALUES vector should be initialized -with pointers to the appropriate argument values. - -To call the function using the initialized ffi_cif, use the -ffi_call function: - -void ffi_call(ffi_cif *cif, void *fn, void *rvalue, void **avalues); - - CIF is a pointer to the ffi_cif initialized specifically - for this function. - - FN is a pointer to the function you want to call. - - RVALUE is a pointer to a chunk of memory that is to hold the - result of the function call. Currently, it must be - at least one word in size (except for the n32 version - under Irix 6.x, which must be a pointer to an 8 byte - aligned value (a long long). It must also be at least - word aligned (depending on the return type, and the - system's alignment requirements). If RTYPE is - &ffi_type_void, this is ignored. If RVALUE is NULL, - the return value is discarded. - - AVALUES is a vector of void* that point to the memory locations - holding the argument values for a call. - If NARGS is 0, this is ignored. - - -If you are expecting a return value from FN it will have been stored -at RVALUE. - - - - An Example - ---------- - -Here is a trivial example that calls puts() a few times. - - #include - #include - - int main() - { - ffi_cif cif; - ffi_type *args[1]; - void *values[1]; - char *s; - int rc; - - /* Initialize the argument info vectors */ - args[0] = &ffi_type_uint; - values[0] = &s; - - /* Initialize the cif */ - if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, - &ffi_type_uint, args) == FFI_OK) - { - s = "Hello World!"; - ffi_call(&cif, puts, &rc, values); - /* rc now holds the result of the call to puts */ - - /* values holds a pointer to the function's arg, so to - call puts() again all we need to do is change the - value of s */ - s = "This is cool!"; - ffi_call(&cif, puts, &rc, values); - } - - return 0; - } - - - - Aggregate Types - --------------- - -Although libffi has no special support for unions or bit-fields, it is -perfectly happy passing structures back and forth. You must first -describe the structure to libffi by creating a new ffi_type object -for it. Here is the definition of ffi_type: - - typedef struct _ffi_type - { - unsigned size; - short alignment; - short type; - struct _ffi_type **elements; - } ffi_type; - -All structures must have type set to FFI_TYPE_STRUCT. You may set -size and alignment to 0. These will be calculated and reset to the -appropriate values by ffi_prep_cif(). - -elements is a NULL terminated array of pointers to ffi_type objects -that describe the type of the structure elements. These may, in turn, -be structure elements. - -The following example initializes a ffi_type object representing the -tm struct from Linux's time.h: - - struct tm { - int tm_sec; - int tm_min; - int tm_hour; - int tm_mday; - int tm_mon; - int tm_year; - int tm_wday; - int tm_yday; - int tm_isdst; - /* Those are for future use. */ - long int __tm_gmtoff__; - __const char *__tm_zone__; - }; - - { - ffi_type tm_type; - ffi_type *tm_type_elements[12]; - int i; - - tm_type.size = tm_type.alignment = 0; - tm_type.elements = &tm_type_elements; - - for (i = 0; i < 9; i++) - tm_type_elements[i] = &ffi_type_sint; - - tm_type_elements[9] = &ffi_type_slong; - tm_type_elements[10] = &ffi_type_pointer; - tm_type_elements[11] = NULL; - - /* tm_type can now be used to represent tm argument types and - return types for ffi_prep_cif() */ - } - - - -Platform Specific Notes -======================= - - Intel x86 - --------- - -There are no known problems with the x86 port. - - Sun SPARC - SunOS 4.1.3 & Solaris 2.x - ------------------------------------- - -You must use GNU Make to build libffi on Sun platforms. - - MIPS - Irix 5.3 & 6.x - --------------------- - -Irix 6.2 and better supports three different calling conventions: o32, -n32 and n64. Currently, libffi only supports both o32 and n32 under -Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be -configured for whichever calling convention it was built for. - -By default, the configure script will try to build libffi with the GNU -development tools. To build libffi with the SGI development tools, set -the environment variable CC to either "cc -32" or "cc -n32" before -running configure under Irix 6.x (depending on whether you want an o32 -or n32 library), or just "cc" for Irix 5.3. - -With the n32 calling convention, when returning structures smaller -than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned. -Here's one way of forcing this: - - double struct_storage[2]; - my_small_struct *s = (my_small_struct *) struct_storage; - /* Use s for RVALUE */ - -If you don't do this you are liable to get spurious bus errors. - -"long long" values are not supported yet. - -You must use GNU Make to build libffi on SGI platforms. - - ARM - System V ABI - ------------------ - -The ARM port was performed on a NetWinder running ARM Linux ELF -(2.0.31) and gcc 2.8.1. - - - - PowerPC System V ABI - -------------------- - -There are two `System V ABI's which libffi implements for PowerPC. -They differ only in how small structures are returned from functions. - -In the FFI_SYSV version, structures that are 8 bytes or smaller are -returned in registers. This is what GCC does when it is configured -for solaris, and is what the System V ABI I have (dated September -1995) says. - -In the FFI_GCC_SYSV version, all structures are returned the same way: -by passing a pointer as the first argument to the function. This is -what GCC does when it is configured for linux or a generic sysv -target. - -EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a -inconsistency with the SysV ABI: When a procedure is called with many -floating-point arguments, some of them get put on the stack. They are -all supposed to be stored in double-precision format, even if they are -only single-precision, but EGCS stores single-precision arguments as -single-precision anyway.

+calls to the CPython eval loop back to the names of the Python +functions and filename being executed. + +Many native performance profilers like the Linux perf tools are +only available to 'see' the C stack when sampling from the profiled +process. This means that if we have the following python code: + + import time + def foo(n): + # Some CPU intensive code + + def bar(n): + foo(n) + + def baz(n): + bar(n) + + baz(10000000) + +A performance profiler that is only able to see native frames will +produce the following backtrace when sampling from foo(): + + _PyEval_EvalFrameDefault -----> Evaluation frame of foo() + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + _PyEval_EvalFrameDefault ------> Evaluation frame of bar() + _PyEval_EvalFrame + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + _PyEval_EvalFrameDefault -------> Evaluation frame of baz() + _PyEval_EvalFrame + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + ... + + Py_RunMain + +Because the profiler is only able to see the native frames and the native +function that runs the evaluation loop is the same (_PyEval_EvalFrameDefault) +then the profiler and any reporter generated by it will not be able to +associate the names of the Python functions and the filenames associated with +those calls, rendering the results useless in the Python world. + +To fix this problem, we introduce the concept of a trampoline frame. A +trampoline frame is a piece of code that is unique per Python code object that +is executed before entering the CPython eval loop. This piece of code just +calls the original Python evaluation function (_PyEval_EvalFrameDefault) and +forwards all the arguments received. In this way, when a profiler samples +frames from the previous example it will see; + + _PyEval_EvalFrameDefault -----> Evaluation frame of foo() + [Jit compiled code 3] + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + _PyEval_EvalFrameDefault ------> Evaluation frame of bar() + [Jit compiled code 2] + _PyEval_EvalFrame + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + _PyEval_EvalFrameDefault -------> Evaluation frame of baz() + [Jit compiled code 1] + _PyEval_EvalFrame + _PyEval_Vector + _PyFunction_Vectorcall + PyObject_Vectorcall + call_function + + ... + + Py_RunMain + +When we generate every unique copy of the trampoline (what here we called "[Jit +compiled code N]") we write the relationship between the compiled code and the +Python function that is associated with it. Every profiler requires this +information in a different format. For example, the Linux "perf" profiler +requires a file in "/tmp/perf-PID.map" (name and location not configurable) +with the following format: + + + +If this file is available when "perf" generates reports, it will automatically +associate every trampoline with the Python function that it is associated with +allowing it to generate reports that include Python information. These reports +then can also be filtered in a way that *only* Python information appears. + +Notice that for this to work, there must be a unique copied of the trampoline +per Python code object even if the code in the trampoline is the same. To +achieve this we have a assembly template in Objects/asm_trampiline.S that is +compiled into the Python executable/shared library. This template generates a +symbol that maps the start of the assembly code and another that marks the end +of the assembly code for the trampoline. Then, every time we need a unique +trampoline for a Python code object, we copy the assembly code into a mmaped +area that has executable permissions and we return the start of that area as +our trampoline function. + +Asking for a mmap-ed memory area for trampoline is very wasteful so we +allocate big arenas of memory in a single mmap call, we populate the entire +arena with copies of the trampoline (this allows us to now have to invalidate +the icache for the instructions in the page) and then we return the next +available chunk every time someone asks for a new trampoline. We keep a linked +list of arenas in case the current memory arena is exhausted and another one is +needed. + +For the best results, Python should be compiled with +CFLAGS="-fno-omit-frame-pointer -mno-omit-leaf-frame-pointer" as this allows +profilers to unwind using only the frame pointer and not on DWARF debug +information (note that as trampilines are dynamically generated there won't be +any DWARF information available for them). +*/ + +#include "Python.h" +#include "pycore_ceval.h" +#include "pycore_frame.h" +#include "pycore_interp.h" + + +#ifdef PY_HAVE_PERF_TRAMPOLINE + +#include +#include +#include +#include +#include +#include + +#if defined(__arm__) || defined(__arm64__) || defined(__aarch64__) +#define PY_HAVE_INVALIDATE_ICACHE + +#if defined(__clang__) || defined(__GNUC__) +extern void __clear_cache(void *, void*); +#endif + +static void invalidate_icache(char* begin, char*end) { +#if defined(__clang__) || defined(__GNUC__) + return __clear_cache(begin, end); +#else + return; +#endif +} +#endif + +/* The function pointer is passed as last argument.

If it is successful, it writes -its findings to stdout, preceded by a line of dashes and a line of the -form: - - Index: - -If the only findings found are suggestions to change a / operator into -a // operator, the output is acceptable input for the Unix 'patch' -program. - -Here are the possible messages on stdout (N stands for a line number): - -- A plain-diff-style change ('NcN', a line marked by '<', a line - containing '---', and a line marked by '>'): - - A / operator was found that should be changed to //. This is the - recommendation when only int and/or long arguments were seen. - -- 'True division / operator at line N' and a line marked by '=': - - A / operator was found that can remain unchanged. This is the - recommendation when only float and/or complex arguments were seen. - -- 'Ambiguous / operator (..., ...) at line N', line marked by '?': - - A / operator was found for which int or long as well as float or - complex arguments were seen. This is highly unlikely; if it occurs, - you may have to restructure the code to keep the classic semantics, - or maybe you don't care about the classic semantics. - -- 'No conclusive evidence on line N', line marked by '*': - - A / operator was found for which no warnings were seen. This could - be code that was never executed, or code that was only executed - with user-defined objects as arguments. You will have to - investigate further. Note that // can be overloaded separately from - /, using __floordiv__. True division can also be separately - overloaded, using __truediv__. Classic division should be the same - as either of those. (XXX should I add a warning for division on - user-defined objects, to disambiguate this case from code that was - never executed?) - -- 'Phantom ... warnings for line N', line marked by '*': - - A warning was seen for a line not containing a / operator. The most - likely cause is a warning about code executed by 'exec' or eval() - (see note below), or an indirect invocation of the / operator, for - example via the div() function in the operator module. It could - also be caused by a change to the file between the time the test - script was run to collect warnings and the time fixdiv was run. - -- 'More than one / operator in line N'; or - 'More than one / operator per statement in lines N-N': - - The scanner found more than one / operator on a single line, or in a - statement split across multiple lines. Because the warnings - framework doesn't (and can't) show the offset within the line, and - the code generator doesn't always give the correct line number for - operations in a multi-line statement, we can't be sure whether all - operators in the statement were executed. To be on the safe side, - by default a warning is issued about this case. In practice, these - cases are usually safe, and the -m option suppresses these warning. - -- 'Can't find the / operator in line N', line marked by '*': - - This really shouldn't happen. It means that the tokenize module - reported a '/' operator but the line it returns didn't contain a '/' - character at the indicated position. - -- 'Bad warning for line N: XYZ', line marked by '*': - - This really shouldn't happen. It means that a 'classic XYZ - division' warning was read with XYZ being something other than - 'int', 'long', 'float', or 'complex'. - -Notes: - -- The augmented assignment operator /= is handled the same way as the - / operator. - -- This tool never looks at the // operator; no warnings are ever - generated for use of this operator. - -- This tool never looks at the / operator when a future division - statement is in effect; no warnings are generated in this case, and - because the tool only looks at files for which at least one classic - division warning was seen, it will never look at files containing a - future division statement. - -- Warnings may be issued for code not read from a file, but executed - using the exec() or eval() functions. These may have - in the filename position, in which case the fixdiv script - will attempt and fail to open a file named '' and issue a - warning about this failure; or these may be reported as 'Phantom' - warnings (see above). You're on your own to deal with these. You - could make all recommended changes and add a future division - statement to all affected files, and then re-run the test script; it - should not issue any warnings. If there are any, and you have a - hard time tracking down where they are generated, you can use the - -Werror option to force an error instead of a first warning, - generating a traceback. - -- The tool should be run from the same directory as that from which - the original script was run, otherwise it won't be able to open - files given by relative pathnames. -""" - -import sys -import getopt -import re -import tokenize - -multi_ok = 0 - -def main(): - try: -

-    This class encapsulates support for HTML Help. Node names,

-    accumulated until a call to finalize(). At that time, three
-    output files are created in the current directory:
-
-        `helpbase`.hhp  is a HTML Help Workshop project file.
-                        It contains various information, some of
-                        which I do not understand; I just copied
-                        the default project info from a fresh
-                        installation.
-        `helpbase`.hhc  is the Contents file for the project.
-        `helpbase`.hhk  is the Index file for the project.
-
-    When these files are used as input to HTML Help Workshop,
-    the resulting file will be named:
-
-        `helpbase`.chm
-
-    If none of the defaults in `helpbase`.hhp are changed,
