Clarified the "At the moment" wording, and added the get_stats entry in the
module summary that Serhiy noted was missing at the end of issue 16351.
Given that pydoc lists all the function docstrings, I'm not sure that module
summary section is actually needed; but, it is probably better to address that
when the module is converted to use Argument Clinic. In the meantime we
should keep the list complete.
Also added versionadded for for fish/csh, fixed indentation of versionadded
for ElementTree.write, and make the behavior of shelf as a context manager
explicit in the docs.
Despite Serhiy's suggestion in issue18529, the emdash just looks
too long to me, at least in my browser. This usage case is sort
of halfway between endash (connective) and emdash (pause/separator).
Also added a note about platform packagers not being required to install
pip by default, if they provide an appropriate pip hook, to the PEP
description section.
This means I moved the 'new expected features' section to the top of the
summary, and made a new section with the same name at the start of
the body, turning the previous top level sections there into subsections.
I also added a line to the new first summary section for modulespec (pep 451).
the function did nothing if the key already exists (if the current value is a
non-NULL pointer).
_testcapi.run_in_subinterp() now correctly sets the new Python thread state of
the current thread when a subinterpreter is created.
The codecs themselves were restored in Python 3.2, this
completes the restoration by adding back the convenience
aliases.
These aliases were originally left out due to confusing
errors when attempting to use them with the text encoding
specific convenience methods. Python 3.4 includes several
improvements to those errors, thus permitting the aliases
to be restored as well.
The utf-16* and utf-32* encoders no longer allow surrogate code points
(U+D800-U+DFFF) to be encoded.
The utf-32* decoders no longer decode byte sequences that correspond to
surrogate code points.
The surrogatepass error handler now works with the utf-16* and utf-32* codecs.
Based on patches by Victor Stinner and Kang-Hao (Kenny) Lu.
- output type errors now redirect users to the type-neutral
convenience functions in the codecs module
- stateless errors that occur during encoding and decoding
will now be automatically wrapped in exceptions that give
the name of the codec involved
importlib.machinery.FileFinder.
While originally moved to stop special-casing '' as PathFinder farther
up the typical call chain now uses the cwd in the instance of '', it
was deemed an unnecessary risk to breaking subclasses of FileFinder to
take the special-casing out.
- cross-references and attributions for inspect changes
- note improvements to inspect and pydoc handling of
metaclasses and dynamic attributes (courtesy of the
enum PEP)
- group all CPython implementation specific changes
into a common section
- add see also links for most of the PEPs
- fix the see also link for the release PEP
- add suitable caveats on Argument Clinic inclusion
- clarify the change to __wrapped__ handling
and stop importlib.machinery.FileFinder treating '' as '.'.
Previous PathFinder transformed '' into '.' which led to __file__ for
modules imported from the cwd to always be relative paths. This meant
the values of the attribute were wrong as soon as the cwd changed.
This change now means that as long as the site module is run (which
makes all entries in sys.path absolute) then all values for __file__
will also be absolute unless it's for __main__ when specified by file
path in a relative way (modules imported by runpy will have an
absolute path).
Now that PathFinder is no longer treating '' as '.' it only makes
sense for FileFinder to stop doing so as well. Now no transformation
is performed for the directory given to the __init__ method.
Thanks to Madison May for the initial patch.
This new pre-initialization API allows embedding
applications like Blender to force a particular
encoding and error handler for the standard IO streams.
Also refactors Modules/_testembed.c to let us start
testing multiple embedding scenarios.
(Initial patch by Bastien Montagne)
This adds EmailMessage and, MIMEPart subclasses of Message
with new API methods, and a ContentManager class used by
the new methods. Also a new policy setting, content_manager.
Patch was reviewed by Stephen J. Turnbull and Serhiy Storchaka,
and reflects their feedback.
I will ideally add some examples of using the new API to the
documentation before the final release.
- Merge from 3.3
- Added to What's New since these are more important in 3.x,
as the bytes<->bytes and str<->str codecs don't fit the
text model convenience methods in 3.x the way they did the
basestring<->basestring methods in the 2.x text model
- Included under Library in Misc/NEWS for the same reason
The GIL must be held to call PyMem_Malloc(), whereas PyOS_Readline() releases
the GIL to read input.
The result of the C callback PyOS_ReadlineFunctionPointer must now be a string
allocated by PyMem_RawMalloc() or PyMem_RawRealloc() (or NULL if an error
occurred), instead of a string allocated by PyMem_Malloc() or PyMem_Realloc().
Fixing this issue was required to setup a hook on PyMem_Malloc(), for example
using the tracemalloc module.
PyOS_Readline() copies the result of PyOS_ReadlineFunctionPointer() into a new
buffer allocated by PyMem_Malloc(). So the public API of PyOS_Readline() does
not change.
The new names are hopefully more descriptive and consistent. If you feel you
don't agree with this change, *please* read issue 17741 first - there's a lot of
discussion in there.
-I
Run Python in isolated mode. This also implies -E and -s. In isolated mode
sys.path contains neither the script’s directory nor the user’s
site-packages directory. All PYTHON* environment variables are ignored,
too. Further restrictions may be imposed to prevent the user from
injecting malicious code.
This was triggered by wanting to make the doctest in email.policy.rst pass;
as_bytes and __bytes__ are clearly useful now that we have BytesGenerator.
Also updated the Message docs to document the policy keyword that was
added in 3.3.
Add new enum:
* PyMemAllocatorDomain
Add new structures:
* PyMemAllocator
* PyObjectArenaAllocator
Add new functions:
* PyMem_RawMalloc(), PyMem_RawRealloc(), PyMem_RawFree()
* PyMem_GetAllocator(), PyMem_SetAllocator()
* PyObject_GetArenaAllocator(), PyObject_SetArenaAllocator()
* PyMem_SetupDebugHooks()
Changes:
* PyMem_Malloc()/PyObject_Realloc() now always call malloc()/realloc(), instead
of calling PyObject_Malloc()/PyObject_Realloc() in debug mode.
* PyObject_Malloc()/PyObject_Realloc() now falls back to
PyMem_Malloc()/PyMem_Realloc() for allocations larger than 512 bytes.
* Redesign debug checks on memory block allocators as hooks, instead of using C
macros
This provides a way to specify arbitrary doctest options when using
the CLI interface to process test files, just as one can when calling
testmod or testfile programmatically.
