raw_data_manager (default for EmailPolicy, EmailMessage)
does correct wrapping of 'text' parts as long as the message contains
characters outside of 7bit US-ASCII set: base64 or qp
Content-Transfer-Encoding is applied if the lines would be too long
without it. It did not, however, do this for ascii-only text,
which could result in lines that were longer than
policy.max_line_length or even the rfc 998 maximum.
This changeset fixes the heuristic so that if lines are longer than
policy.max_line_length, it will always apply a
content-transfer-encoding so that the lines are wrapped correctly.
Move PyInterpreterState.fs_codec into a new
PyInterpreterState.unicode structure.
Give a name to the fs_codec structure and use this structure in
unicodeobject.c.
The previous commits on bpo-29587 got exception chaining working
with gen.throw() in the `yield` case. This patch also gets the
`yield from` case working.
As a consequence, implicit exception chaining now also works in
the asyncio scenario of awaiting on a task when an exception is
already active.
Tests are included for both the asyncio case and the pure
generator-only case.
Don't hardcode defining_class parameter name to "cls":
* Define CConverter.set_template_dict(): do nothing by default
* CLanguage.render_function() now calls set_template_dict() on all
converters.
This commit fixes SyntaxError locations when the caret is not displayed,
by doing the following:
- `col_number` always gets set to the location of the offending
node/expr. When no caret is to be displayed, this gets achieved
by setting the object holding the error line to None.
- Introduce a new function `_PyPegen_raise_error_known_location`,
which can be called, when an arbitrary `lineno`/`col_offset`
needs to be passed. This function then gets used in the grammar
(through some new macros and inline functions) so that SyntaxError
locations of the new parser match that of the old.
_Py_hashtable_get_entry_ptr() avoids comparing the entry hash:
compare directly keys.
Move _Py_hashtable_get_entry_ptr() just after
_Py_hashtable_get_entry_generic().
_Py_hashtable_t values become regular "void *" pointers.
* Add _Py_hashtable_entry_t.data member
* Remove _Py_hashtable_t.data_size member
* Remove _Py_hashtable_t.get_func member. It is no longer needed
to specialize _Py_hashtable_get() for a specific value size, since
all entries now have the same size (void*).
* Remove the following macros:
* _Py_HASHTABLE_GET()
* _Py_HASHTABLE_SET()
* _Py_HASHTABLE_SET_NODATA()
* _Py_HASHTABLE_POP()
* Rename _Py_hashtable_pop() to _Py_hashtable_steal()
* _Py_hashtable_foreach() callback now gets key and value rather than
entry.
* Remove _Py_hashtable_value_destroy_func type. value_destroy_func
callback now only has a single parameter: data (void*).
Rewrite _tracemalloc to store "trace_t*" rather than directly
"trace_t" in traces hash tables. Traces are now allocated on the heap
memory, outside the hash table.
Add tracemalloc_copy_traces() and tracemalloc_copy_domains() helper
functions.
Remove _Py_hashtable_copy() function since there is no API to copy a
key or a value.
Remove also _Py_hashtable_delete() function which was commented.
Rewrite _Py_hashtable_t type to always store the key as
a "const void *" pointer. Add an explicit "key" member to
_Py_hashtable_entry_t.
Remove _Py_hashtable_t.key_size member.
hash and compare functions drop their hash table parameter, and their
'key' parameter type becomes "const void *".
Rewrite how the _tracemalloc module stores traces of other domains.
Rather than storing the domain inside the key, it now uses a new hash
table with the domain as the key, and the data is a per-domain traces
hash table.
* Add tracemalloc_domain hash table.
* Remove _Py_tracemalloc_config.use_domain.
* Remove pointer_t and related functions.
Add a new _Py_HashPointerRaw() function which avoids replacing -1
with -2 to micro-optimize hash table using pointer keys: using
_Py_hashtable_hash_ptr() hash function.
Optimize _Py_hashtable_get() and _Py_hashtable_get_entry() for
pointer keys:
* key_size == sizeof(void*)
* hash_func == _Py_hashtable_hash_ptr
* compare_func == _Py_hashtable_compare_direct
Changes:
* Add get_func and get_entry_func members to _Py_hashtable_t
* Convert _Py_hashtable_get() and _Py_hashtable_get_entry() functions
to static nline functions.
* Add specialized get and get entry for pointer keys.
In translate(), generate unique group names across calls.
The restores the undocumented ability to get a valid regexp
by joining multiple translate() results via `|`.
_Py_hashtable_new() now uses PyMem_Malloc/PyMem_Free allocator by
default, rather than PyMem_RawMalloc/PyMem_RawFree.
PyMem_Malloc is faster than PyMem_RawMalloc for memory blocks smaller
than or equal to 512 bytes.
* Move Modules/hashtable.h to Include/internal/pycore_hashtable.h
* Move Modules/hashtable.c to Python/hashtable.c
* Python is now linked to hashtable.c. _tracemalloc is no longer
linked to hashtable.c. Previously, marshal.c got hashtable.c via
_tracemalloc.c which is built as a builtin module.
Avoid unnecessary overhead in _PyDict_GetItemIdWithError() by calling
_PyDict_GetItem_KnownHash() instead of the more generic PyDict_GetItemWithError(),
since we already know the hash of interned strings.
With the new parser, the error message contains always the trailing
newlines, causing the comparison of the repr of the error messages
in codeop to fail. This commit makes the new parser mirror the old parser's
behaviour regarding trailing newlines.
* bpo-37986: Improve perfomance of PyLong_FromDouble()
* Use strict bound check for safety and symmetry
* Remove possibly outdated performance claims

Convert posixmodule.c ("posix" or "nt" module) to the multiphase
initialization (PEP 489).
* Create the module using PyModuleDef_Init().
* Create ScandirIteratorType and DirEntryType with the new
PyType_FromModuleAndSpec() (PEP 573)
* Get the module state from ScandirIteratorType and DirEntryType with
the new PyType_GetModule() (PEP 573)
* Pass module to functions which access the module state.
* convert_sched_param() gets a new module parameter. It is now called
directly since Argument Clinic doesn't support passing the module
to an argument converter callback.
* Remove _posixstate_global macro.
This is for the C generator:
- Disallow rule and variable names starting with `_`
- Rename most local variable names generated by the parser to start with `_`
Exceptions:
- Renaming `p` to `_p` will be a separate PR
- There are still some names that might clash, e.g.
- anything starting with `Py`
- C reserved words (`if` etc.)
- Macros like `EXTRA` and `CHECK`
* bpo-39791: Update importlib.resources to support files() API (importlib_resources 1.5).
* 📜🤖 Added by blurb_it.
* Add some documentation about the new objects added.
