The reference to administrative data was confusing to readers,
so this simplifies the note to explain that deep copying may copy
more then you intended, such as data that you expected to be
shared between copies.

conn.set_trace_callback() shouldn't be called multiple times when the
schema is changing.

This has indirectly been fixed by using sqlite3_prepare_v2() in bpo-9303.

The original attempted fix missed an `isdir()` call in
`get_base_branch()`.

Also changed format specifier for function name from "%s" to "%.200s"
and exception messages should start with lowercase letter.

Documents a few omitted classes and adds NamedTuple methods.

attributes.

object.__reduce__() no longer takes arguments, object.__reduce_ex__() now
requires one argument.

bpo-28837: Fix lib2to3 handling of map/zip/filter calls when followed with a 'trailer', e.g. zip()[x] (#24)

* Implement math.remainder.

* Fix markup for arguments; use double spaces after period.

* Mark up function reference in what's new entry.

* Add comment explaining the calculation in the final branch.

* Fix out-of-order entry in whatsnew.

* Add comment explaining why it's good enough to compare m with c, in spite of possible rounding error.

This hides unwanted implementation details from tracebacks.

* Updates B.index documentation.

* Updates str.index documentation, makes it Argument Clinic compatible.

* Removes ArgumentClinic code.

* Finishes string.index documentation.

* Updates string.rindex documentation.

* Documents B.rindex.

* correct parse_qs and parse_qsl test case descriptions.

* bpo-29972: Fix test_eintr on AIX

On AIX, sigtimedwait(0.2) sleeps 199.8 ms, whereas the test expects
200 ms or longer.

* bpo-29972: Skip some inet_pton() tests on AIX

Skip some inet_pton() tests of test_socket on AIX.

inet_pton() on AIX is less strict than on Linux and doesn't reject
some invalid IP addresses. The unit tests test more the libc than
Python itself.

* bpo-29972: Skip tests known to fail on AIX

* test_locale.test_strcoll_with_diacritic()
* test_locale.test_strxfrm_with_diacritic()
* test_strptime.test_week_of_year_and_day_of_week_calculation()
* test_tools.test_POT_Creation_Date()

* bpo-29725: DOC: add text for arraysize in sqlite3.Cursor

Don't fail anymore if test run with python3 -Werror.

Fix also deprecation message: add a space.

Move the `.. index` directive to more appropriate place.

Return 304 response if file was not modified.

* change LBYL key lookup to dict.setdefault

The ``results`` was constructed as a defaultdict and we could simply
delete the check ``if key not in results``. However, I think it's safer
to use dict.setdefault as I'm not sure whether the caller expects a
regular dict or defaultdict.

* add name to the acknowledgements file

* use defaultdict to make the key-lookup cleaner

Revert "Minor factoring:  move redundant resize scaling logic into the resize function."

This reverts commit 48973002.

This reverts commit b94d7fd4.

the original logic was just comparing the network address
but this is wrong because if the network address is equal then
we need to compare the ip address for breaking the tie

add more ip_interface comparison tests

Also uncomment and fix a path test.

objects when pass out of bound fold argument.

Fix MemoryError caused by moving around code in PR #886; nbytes was sometimes used unitinitalized (in non-debug builds, when use_calloc was false and elsize was 0).
