* bpo-39351: Remove base64.encodestring() (GH-18022)Victor Stinner2020-01-162-12/+5
| | | | | 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 Olshansky2020-01-151-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* bpo-38630: Fix subprocess.Popen.send_signal() race condition (GH-16984)Victor Stinner2020-01-151-0/+2
| | | | | | | 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.
