* Remove timeout_started * Remove timeout member
* Remove unused db member of pysqlite_Statement * Remove unused sql method from statement object
1. SyntaxError args have a tuple of other attributes. 2. Attributes are adjusted for errors in f-string field expressions. 3. Compile() can raise SyntaxErrors.
#22659) * `ensurepip` now uses `importlib.resources.files()` traversable APIs * Update Lib/ensurepip/__init__.py Co-authored-by: Jason R. Coombs <jaraco@jaraco.com> * Update Misc/NEWS.d/next/Library/2020-10-11-20-23-48.bpo-37449.f-t3V6.rst Co-authored-by: Jason R. Coombs <jaraco@jaraco.com> Co-authored-by: Jason R.

…H-26422) * bpo-44258: support PEP 515 for Fraction's initialization from string * regexps's version * A different regexps version, which doesn't suffer from catastrophic backtracking * revert denom -> den * strip "_" from the decimal str, add few tests * drop redundant tests * Add versionchanged & whatsnew entry * Amend Fraction constructor docs * Change .. versionchanged:...
* Add co_firstinstr field to code object. * Implement barebones quickening. * Use non-quickened bytecode when tracing. * Add NEWS item * Add new file to Windows build. * Don't specialize instructions with EXTENDED_ARG.
These were reverted in gh-26530 (commit 17c4edc) due to refleaks. * 2c1e258 - Compute deref offsets in compiler (gh-25152) * b2bf2bc - Add new internal code objects fields: co_fastlocalnames and co_fastlocalkinds. (gh-26388) This change fixes the refleaks. https://bugs.python.org/issue43693
… precision time source (GH-26568)
Relative imports do not work when running test_x as main.
…s. (gh-26396) This moves logic out of the frame initialization code and into the compiler and eval loop. Doing so simplifies the runtime code and allows us to optimize it better. https://bugs.python.org/issue43693
The plan is to eventually make PyCodeObject opaque in the public C-API, with the full struct moved to Include/internal/pycore_code.h. _PyLocalsPlusKinds and _PyLocalsPlusKind started off there but were needed on PyCodeObject, hence the duplication. This led to warnings with some compilers. (Apparently it does not trigger a warning on my install of GCC.) This change eliminates the superfluous typedef. https://bugs.python.org/issue43693
They are slow and raise too many false positive, I'm in the slow process to try to change this.
Call SQLite API's first, and return early in case of error. At the end, allocate the object and initialise members. We now avoid unneeded alloc/dealloc's in case the statement creation fails.

…H-26593) These are the settings that extend the help menu. Moving them shortens the dialog and will help with it being too tall for small screens.
This was reverted in GH-26596 (commit 6d518bb) due to some bad memory accesses. * Add the MAKE_CELL opcode. (gh-26396) The memory accesses have been fixed. https://bugs.python.org/issue43693
…-25466) Emit a deprecation warning if the numeric literal is immediately followed by one of keywords: and, else, for, if, in, is, or. Raise a syntax error with more informative message if it is immediately followed by other keyword or identifier. Automerge-Triggered-By: GH:pablogsal
…g in syntax errors (GH-26611)
Currently, if an arg value escapes (into the closure for an inner function) we end up allocating two indices in the fast locals even though only one gets used. Additionally, using the lower index would be better in some cases, such as with no-arg `super()`. To address this, we update the compiler to fix the offsets so each variable only gets one "fast local". As a consequence, now some cell offsets are interspersed with the locals (only when an arg escapes to an inner function). https://bugs.python.org/issue43693
* Remove struct _node from the stable ABI list This struct was removed along with the old parser in Python 3.9 (PEP 617) * Stable ABI list: Use the public name "PyFrameObject" rather than "_frame" * Ensure limited API doesn't contain private names Names prefixed by an underscore are private by definition. * Add a blurb
The _bootstrap_inner() method of threading.Thread now reuses its _delete() method rather than accessing _active() directly. It became possible since _active_limbo_lock became reentrant. Moreover, it no longer ignores any exception when deleting the thread from the _active dictionary.
1. Remove conditions already checked by assert() 2. Remove object_init() call that effectively creates an empty tuple and checks that this tuple is empty
Also fix stable ABI type definitions
…nge it to 'num'. (GH-26744)
`ssl.SSL_NO_TLS` should be `ssl.OP_NO_TLS`.
…26351) * Make functools types immutable * Multibyte codec types are now immutable * pyexpat.xmlparser is now immutable * array.arrayiterator is now immutable * _thread types are now immutable * _csv types are now immutable * _queue.SimpleQueue is now immutable * mmap.mmap is now immutable * unicodedata.UCD is now immutable * sqlite3 types are now immutable * _lsprof.Profiler is now immutable * _overlapped.Overlapped is now immutable * _operator types are now immutable * winapi__overlapped.Overlapped is now immutable * _lzma types are now immutable * _bz2 types are now immutable * _dbm.dbm and _gdbm.gdbm are now immutable
…ct. Reverts behavior to that of 3.10 and earlier. (GH-26768)

* [Enum] reduce scope of new format behavior
Instead of treating all Enums the same for format(), only user mixed-in
enums will be affected. In other words, IntEnum and IntFlag will not be
changing the format() behavior, due to the requirement that they be
drop-in replacements of existing integer constants.
If a user creates their own integer-based enum, then the new behavior
will apply:
class Grades(int, Enum):
A = 5
B = 4
C = 3
D = 2
F = 0
Now: format(Grades.B) -> DeprecationWarning and '4'
3.12: -> no warning, and 'B'
Remove the weakref example. If a new instance is created and the same arguments are passes, it raises a ReferenceError.

1. Rewrite ThreadTests with a _run_test() helper method that does the heavy lifting 2. Add test.support.threading_helper.reap_threads to _run_test() 3. Use _run_test() in all threading tests 4. Add test case for sqlite3.Connection.set_trace_callback 5. Add test case for sqlite3.Connection.create_collation

Test for execution of the body was null. It would pass even if the code which should be skipped was executed.
