* Fix `mock.patch.dict` to be stopped with `mock.patch.stopall` (#17606)Mario Corchero2020-01-241-0/+2
| | | | | As the function was not registering in the active patches, the mocks started by `mock.patch.dict` were not being stopped when `mock.patch.stopall` was being called.
* bpo-29435: Allow is_tarfile to take a filelike obj (GH-18090)William Woodruff2020-01-231-0/+2
| | | `is_tarfile()` now supports `name` being a file or file-like object.
* bpo-35182: fix communicate() crash after child closes its pipes (GH-17020) ↵Alex Rebert2020-01-221-0/+3
| | | | | | | | | (GH-18117) When communicate() is called in a loop, it crashes when the child process has already closed any piped standard stream, but still continues to be running Co-authored-by: Andriy Maletsky <andriy.maletsky@gmail.com>
* bpo-39366: Remove xpath() and xgtitle() methods of NNTP (GH-18035)Dong-hee Na2020-01-221-0/+2

* bpo-39406: Implement os.putenv() with setenv() if available (GH-18128)Victor Stinner2020-01-221-0/+3
| | | | | If setenv() C function is available, os.putenv() is now implemented with setenv() instead of putenv(), so Python doesn't have to handle the environment variable memory.
* Revert "bpo-39413: Implement os.unsetenv() on Windows (GH-18104)" (GH-18124)Victor Stinner2020-01-221-1/+0
| | | This reverts commit 56cd3710a1ea3ba872d345ea1bebc86ed08bc8b8.
* bpo-39353: Deprecate the binhex module (GH-18025)Victor Stinner2020-01-221-0/+4
| | | | | | | | Deprecate binhex4 and hexbin4 standards. Deprecate the binhex module and the following binascii functions: * b2a_hqx(), a2b_hqx() * rlecode_hqx(), rledecode_hqx() * crc_hqx()
* bpo-39413: Implement os.unsetenv() on Windows (GH-18104)Victor Stinner2020-01-211-0/+1
| | | | | The os.unsetenv() function is now also available on Windows. It is implemented with SetEnvironmentVariableW(name, NULL).
* bpo-39389: gzip: fix compression level metadata (GH-18077)William Chargin2020-01-211-0/+2
| | | | | | 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.
* bpo-39396: Fix math.nextafter(-0.0, +0.0) on AIX 7.1 (GH-18094)Victor Stinner2020-01-211-0/+1
| | | | Move also math.nextafter() on math.ulp() tests from IsCloseTests to MathTests.

* bpo-39357: Remove buffering parameter of bz2.BZ2File (GH-18028)Victor Stinner2020-01-161-0/+4
| | | | | | | 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-39350: Remove deprecated fractions.gcd() (GH-18021)Victor Stinner2020-01-161-0/+2
| | | | Remove fractions.gcd() function, deprecated since Python 3.5 (bpo-22486): use math.gcd() instead.
* bpo-39351: Remove base64.encodestring() (GH-18022)Victor Stinner2020-01-161-0/+3
| | | | | Remove base64.encodestring() and base64.decodestring(), aliases deprecated since Python 3.1: use base64.encodebytes() and base64.decodebytes() instead.
* bpo-37958: Adding get_profile_dict to pstats (GH-15495)Daniel Olshansky2020-01-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* bpo-38630: Fix subprocess.Popen.send_signal() race condition (GH-16984)Victor Stinner2020-01-151-0/+5
| | | | | | | 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.

| | | | | | | | | | The default value of "ident" parameter should be sys.argv[0] with leading path components stripped, but it contained the last slash, i.e. '/program' instead of 'program'. BPO issue: https://bugs.python.org/issue38361 https://bugs.python.org/issue38361

* bpo-38293: Allow shallow and deep copying of property objects (GH-16438)Guðni Natan Gunnarsson2020-01-121-0/+1
| | | | | | | | | | | | | | | | | | Copying property objects results in a TypeError. Steps to reproduce: ``` >>> import copy >>> obj = property() >>> copy.copy(obj) ```` This affects both shallow and deep copying. My idea for a fix is to add property objects to the list of "atomic" objects in the copy module. These already include types like functions and type objects. I also added property objects to the unit tests test_copy_atomic and test_deepcopy_atomic. This is my first PR, and it's highly likely I've made some mistake, so please be kind :) https://bugs.python.org/issue38293

| | | | | nntplib.NNTP and nntplib.NNTP_SSL now raise a ValueError if the given timeout for their constructor is zero to prevent the creation of a non-blocking socket.

* bpo-38615: Add timeout parameter for IMAP4 and IMAP4_SSL constructor (GH-17203)Dong-hee Na2020-01-071-0/+5
| | | | | | | | imaplib.IMAP4 and imaplib.IMAP4_SSL now have an optional *timeout* parameter for their constructors. Also, the imaplib.IMAP4.open() method now has an optional *timeout* parameter with this change. The overridden methods of imaplib.IMAP4_SSL and imaplib.IMAP4_stream were applied to this change.

| | | | | | | This uses the heuristic of assuming a named tuple is a subclass of tuple with a _fields attribute. This change means that contents of a named tuple wouldn't be converted - if a user wants to have ConvertingTuple functionality from a namedtuple, they will have to implement it themselves.
