bpo-32137: The repr of deeply nested dict now raises a RecursionError (#4570)
instead of crashing due to a stack overflow.

This perhaps will fix similar problems in other extension types.

bpo-32030: Add more options to _PyCoreConfig (#4485)
Py_Main() now handles two more -X options:

* -X showrefcount: new _PyCoreConfig.show_ref_count field
* -X showalloccount: new _PyCoreConfig.show_alloc_count field

2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397)
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

7e160ce356 Issue #23034: The output of a special Python build with defined COUNT_ALLOCS,
SHOW_ALLOC_COUNT or SHOW_TRACK_COUNT macros is now off by  default.  It can
be re-enabled using the "-X showalloccount" option.  It now outputs to stderr
instead of stdout.

1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR.
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
This patch doesn't fix bugs and hence there is no need to backport it.

c5cc5011ac Make the various iterators' "setstate" sliently and consistently clip the
index.  This avoids the possibility of setting an iterator to an invalid
state.

34bdeb5d81 Add a comment about *not* caching the hash value. Issue #9685 suggested to memorize the hash value, but the feature request was rejected because no speed ups were found. 2013-01-07 21:24:18 +01:00

c2176e46d7 Fix the internals of our hash functions to used unsigned values during hash
computation as the overflow behavior of signed integers is undefined.

NOTE: This change is smaller compared to 3.2 as much of this cleanup had
already been done.  I added the comment that my change in 3.2 added so that the
code would match up.  Otherwise this just adds or synchronizes appropriate UL
designations on some constants to be pedantic.

In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent.

Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).

Cleanup only - no functionality or hash values change.

Gregory P. Smith
63e6c3222f Consolidate the occurrances of the prime used as the multiplier when hashing
to a single #define instead of having several copies in several files.

This excludes the Modules/ tree (datetime and expat both have a copy
for their own purposes with no need for it to be the same).
