v0.4.9

Implement dynamic string structs to reflect CPython implementation:

• PyASCIIObject
• PyCompactUnicodeObject
• PyUnicodeObject

Added some macros to py_unicode

These should exactly match their C equivalents when possible

• PyUnicode_DATA
• PyUnicode_IS_COMPACT_ASCII
• PyUnicode_UTF8_LENGTH
• PyUnicode_WSTR_LENGTH
• _PyUnicode_COMPACT_DATA
• _PyUnicode_HAS_UTF8_MEMORY
• _PyUnicode_HAS_WSTR_MEMORY
• _PyUnicode_NONCOMPACT_DATA
• _PyUnicode_UTF8
• _PyUnicode_UTF8_LENGTH

Added MutableSequence methods for StrView:

• __delitem__ (index / slice)
• __setitem__ (index / slice)
• append
• clear
• extend
• insert
• pop
• remove
• reverse

These new methods will not require an unsafe context normally as they check the allocated memory bounds before any resize operation. If resizing will be beyond allocated memory, an UnsafeError is raised.

An unsafe context can be entered to bypass this allocated memory check.

Fixes:

• ViewStr will now dynamically use one of PyASCIIObject, PyCompactUnicodeObject, or PyUnicodeObject structs. Previously the single usage of PyUnicodeObject could cause out of bounds memory access.
• PyASCIIObject and subtypes now use a mem_size that is logically equivalent to the C implementation of str.__sizeof__, and should match in all cases.

v0.4.8

Added

• Py.Mem api methods (Malloc, Calloc, Realloc)
• Add try_from and with_ref methods to PyObject

Fixes and Enhancements

• Simplify PyUnicode field access
• ListView and TupleView ob_item setters now will cast from PyObject and objects to the required ptr[PyObject] types

Full Changelog: v0.4.7...v0.4.8

v0.4.7

Enhancements

• Expand PyTupleObject.ob_digit setter compatibility for casts

Docs

• Improve documentation coverage

Full Changelog: v0.4.6...v0.4.7

v0.4.6

Added MutableSequence protocols for TupleView:

• __getitem__ (index / slice)
• __setitem__ (index / slice)
• __delitem__ (index / slice)
• __iadd__
• append
• clear
• extend
• insert
• pop
• remove
• reverse

These new methods will not require an unsafe context normally as they check the allocated memory bounds before any resize operation. If resizing will be beyond allocated memory for the tuple, an UnsafeError is raised.

An unsafe context can be entered to bypass this allocated memory check.

Fixes

• Fixed DictView.__getitem__ missing PyObject cast
• TupleView mem_size uses base implementation from PyTupleObject for increased accuracy

v0.4.6a1

Added MutableSequence protocols for TupleView:

• __delitem__ (index / slice)
• __setitem__ (index / slice)
• __iadd__
• append
• clear
• extend
• insert
• pop
• remove
• reverse

These new methods will not require an unsafe context normally as they check the allocated memory bounds before any resize operation. If resizing will be beyond allocated memory for the tuple, an UnsafeError is raised.

An unsafe context can be entered to bypass this allocated memory check.

• TupleView.mem_size now uses more accurate implementation from PyTupleObject

Docs
