* PyLong_AsLongLong() docs should say 'long long' (#18082)Keith Erskine2020-01-211-1/+1
|
* bpo-39406: Add PY_PUTENV_DICT macro to posixmodule.c (GH-18106)Victor Stinner2020-01-211-15/+37
| | | Rename posix_putenv_garbage to putenv_dict.
* bpo-39413: Implement os.unsetenv() on Windows (GH-18104)Victor Stinner2020-01-216-12/+92
| | | | | The os.unsetenv() function is now also available on Windows. It is implemented with SetEnvironmentVariableW(name, NULL).
* Move test_math tests (GH-18098)Victor Stinner2020-01-211-148/+148
| | | | | testPerm() and testComb() belong to MathTests, not to IsCloseTests(). test_nextafter() and test_ulp() now use assertIsNaN().

| | | | | | Replace int with intptr_t to fix the warning: objects\frameobject.c(341): warning C4244: 'initializing': conversion from '__int64' to 'int', possible loss of data
* bpo-39389: gzip: fix compression level metadata (GH-18077)William Chargin2020-01-213-3/+31
| | | | | | As described in RFC 1952, section 2.3.1, the XFL (eXtra FLags) byte of a gzip member header should indicate whether the DEFLATE algorithm was tuned for speed or compression ratio. Prior to this patch, archives emitted by the `gzip` module always indicated maximum compression.

* Fix Lock.locked() to remove extra bold highlighting (#18042)Grant Jenks2020-01-171-0/+1
|
* bpo-39356, zipfile: Remove code handling DeprecationWarning (GH-18027)Victor Stinner2020-01-171-19/+9
| | | | | | | | Remove old "except DeprecationWarning:" code path added by commit bf02e3bb21b2d75cba4ce409a14ae64dbc2dd6d2. It's no longer needed. struct.pack() no longer emit DeprecationWarning if getting a float whereas an integer is expected. It now raises an hard error instead.
* bpo-39357: Update bz2 docstring: remove buffering (GH-18036)Victor Stinner2020-01-171-2/+0
| | | Thanks Karthikeyan Singaravelan for the report ;-)
* bpo-39357: Remove buffering parameter of bz2.BZ2File (GH-18028)Victor Stinner2020-01-165-15/+26
| | | | | | | Remove the buffering parameter of bz2.BZ2File. Since Python 3.0, it was ignored and using it was emitting a DeprecationWarning. Pass an open file object to control how the file is opened. The compresslevel parameter becomes keyword-only.
* bpo-31031: Unify duplicate bits_in_digit and bit_length (GH-2866)Niklas Fiekas2020-01-164-54/+35
| | | Add _Py_bit_length() to unify duplicate bits_in_digit() and bit_length().
* bpo-39350: Remove deprecated fractions.gcd() (GH-18021)Victor Stinner2020-01-165-60/+9
| | | | Remove fractions.gcd() function, deprecated since Python 3.5 (bpo-22486): use math.gcd() instead.
* bpo-39351: Remove base64.encodestring() (GH-18022)Victor Stinner2020-01-165-36/+8
| | | | | Remove base64.encodestring() and base64.decodestring(), aliases deprecated since Python 3.1: use base64.encodebytes() and base64.decodebytes() instead.
* bpo-39348: Fix code highlight for the SOCK_NONBLOCK example (GH-18018)Oz N Tiram2020-01-151-1/+3
| | | | | | | | | | | The previous double colon was wrongly place directly after Therefore. Which produced a block without syntax highlighting. This fixes it by separating the double colon from the text. As a result, sphinx now properly highlights the python code. https://bugs.python.org/issue39348
* bpo-37958: Adding get_profile_dict to pstats (GH-15495)Daniel Olshansky2020-01-154-4/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pstats is really useful or profiling and printing the output of the execution of some block of code, but I've found on multiple occasions when I'd like to access this output directly in an easily usable dictionary on which I can further analyze or manipulate. The proposal is to add a function called get_profile_dict inside of pstats that'll automatically return this data the data in an easily accessible dict. The output of the following script: ``` import cProfile, pstats import pprint from pstats import func_std_string, f8 def fib(n): if n == 0: return 0 if n == 1: return 1 return fib(n-1) + fib(n-2) pr = cProfile.Profile() pr.enable() fib(5) pr.create_stats() ps = pstats.Stats(pr).sort_stats('tottime', 'cumtime') def get_profile_dict(self, keys_filter=None): """ Returns a dict where the key is a function name and the value is a dict with the following keys: - ncalls - tottime - percall_tottime - cumtime - percall_cumtime - file_name - line_number keys_filter can be optionally set to limit the key-value pairs in the retrieved dict. """ pstats_dict = {} func_list = self.fcn_list[:] if self.fcn_list else list(self.stats.keys()) if not func_list: return pstats_dict pstats_dict["total_tt"] = float(f8(self.total_tt)) for func in func_list: cc, nc, tt, ct, callers = self.stats[func] file, line, func_name = func ncalls = str(nc) if nc == cc else (str(nc) + '/' + str(cc)) tottime = float(f8(tt)) percall_tottime = -1 if nc == 0 else float(f8(tt/nc)) cumtime = float(f8(ct)) percall_cumtime = -1 if cc == 0 else float(f8(ct/cc)) func_dict = { "ncalls": ncalls, "tottime": tottime, # time spent in this function alone "percall_tottime": percall_tottime, "cumtime": cumtime, # time spent in the function plus all functions that this function called, "percall_cumtime": percall_cumtime, "file_name": file, "line_number": line } func_dict_filtered = func_dict if not keys_filter else { key: func_dict[key] for key in keys_filter } pstats_dict[func_name] = func_dict_filtered return pstats_dict pp = pprint.PrettyPrinter(depth=6) pp.pprint(get_profile_dict(ps)) ``` will produce: ``` {"<method 'disable' of '_lsprof.Profiler' objects>": {'cumtime': 0.0, 'file_name': '~', 'line_number': 0, 'ncalls': '1', 'percall_cumtime': 0.0, 'percall_tottime': 0.0, 'tottime': 0.0}, 'create_stats': {'cumtime': 0.0, 'file_name': '/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/cProfile.py', 'line_number': 50, 'ncalls': '1', 'percall_cumtime': 0.0, 'percall_tottime': 0.0, 'tottime': 0.0}, 'fib': {'cumtime': 0.0, 'file_name': 'get_profile_dict.py', 'line_number': 5, 'ncalls': '15/1', 'percall_cumtime': 0.0, 'percall_tottime': 0.0, 'tottime': 0.0}, 'total_tt': 0.0} ``` As an example, this can be used to generate a stacked column chart using various visualization tools which will assist in easily identifying program bottlenecks. https://bugs.python.org/issue37958 Automerge-Triggered-By: @gpshead
* Fix typo in multiprocessing.pool.AsyncResult.successful doc. (GH-17932)Antoine2020-01-151-1/+1
| | | | | | | | Since 3.7 `successful` raises a `ValueError` as explained in the next text block from the documentation: _Changed in version 3.7: If the result is not ready, ValueError is raised instead of AssertionError._ No issue associated with this PR. Should be backported in 3.7 and 3.8.
* Fix compiler warning on Windows (GH-18012)Ammar Askar2020-01-151-1/+1
| | | | | | | | Python-ast.h contains a macro named Yield that conflicts with the Yield macro in Windows system headers. While Python-ast.h has an "undef Yield" directive to prevent this, it means that Python-ast.h must be included before Windows header files or we run into a re-declaration warning. In commit c96be811fa7d an include for pycore_pystate.h was added which indirectly includes Windows header files. In this commit we re-order the includes to fix this warning.
* bpo-38630: Fix subprocess.Popen.send_signal() race condition (GH-16984)Victor Stinner2020-01-154-3/+57
| | | | | | | On Unix, subprocess.Popen.send_signal() now polls the process status. Polling reduces the risk of sending a signal to the wrong process if the process completed, the Popen.returncode attribute is still None, and the pid has been reassigned (recycled) to a new different process.

* venv: Suppress warning message when bash hashing is disabled. (GH-17966)Dima2020-01-141-2/+2
| | | | | | | | | | | | | When using python's built-in venv activaton script warnings are printed when hashing is disabled in bash or zsh, like; `bash: hash: hashing disabled` This output is not really useful to the end-user and has been disabled in `virtualenv` for long.
