bpo-41972: Use the two-way algorithm for string searching (GH-22904)
...
Implement an enhanced variant of Crochemore and Perrin's Two-Way string searching algorithm, which reduces worst-case time from quadratic (the product of the string and pattern lengths) to linear. This applies to forward searches (like``find``, ``index``, ``replace``); the algorithm for reverse searches (like ``rfind``) is not changed.

bpo-39939: Add str.removeprefix and str.removesuffix (GH-18939)
...
Added str.removeprefix and str.removesuffix methods and corresponding
bytes, bytearray, and collections.UserString methods to remove affixes
from a string if present. See PEP 616 for a full description.

bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)
...
The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.

Issue #26257 : Eliminate buffer_tests.py and fix ByteArrayAsStringTest
...
ByteArrayAsStringTest.fixtype() was converting test data to bytes, not byte-
array, therefore many of the test cases inherited in this class were not
actually being run on the bytearray type.
The tests in buffer_tests.py were redundant with methods in string_tests
.MixinStrUnicodeUserStringTest and string_tests.CommonTest. These methods are
now moved into string_tests.BaseTest, where they will also get run for bytes
and bytearray.
This change also moves test_additional_split(), test_additional_rsplit(), and
test_strip() from CommonTest to BaseTest, meaning these tests are now run for
bytes and bytearray. I plan to eliminate redundancies with existing tests in
test_bytes.py soon.

Issue #19587 : Remove masked and redundant tests in test_bytes

* test_contains() did not override anything
* test_expandtabs/upper/lower() in FixedStringTest were masking usable tests
in string_tests. These tests now get run for bytearray() and bytes().
* test_expandtabs/upper/lower() in buffer_tests were only run on bytearray()
and are redundant with string_tests
