New submission from STINNER Victor: Is it too late in Python 3.4 release process to add a new method to classes of the tracemalloc module?
Here is a patch which adds unit tests and uses the new method in the documentation. Example before: Top 10 lines #1: collections/__init__.py:368: 291.9 KiB #2: Lib/doctest.py:1291: 200.2 KiB #3: unittest/case.py:571: 160.3 KiB #4: Lib/abc.py:133: 99.8 KiB #5: urllib/parse.py:476: 71.8 KiB #6: <string>:5: 62.7 KiB #7: Lib/base64.py:140: 59.8 KiB #8: Lib/_weakrefset.py:37: 51.8 KiB #9: collections/__init__.py:362: 50.6 KiB #10: test/test_site.py:56: 48.0 KiB 7496 other: 4161.9 KiB Total allocated size: 5258.8 KiB Example after: Top 10 lines #1: Lib/base64.py:414: 419.8 KiB _b85chars2 = [(a + b) for a in _b85chars for b in _b85chars] #2: Lib/base64.py:306: 419.8 KiB _a85chars2 = [(a + b) for a in _a85chars for b in _a85chars] #3: collections/__init__.py:368: 293.6 KiB exec(class_definition, namespace) #4: Lib/abc.py:133: 115.2 KiB cls = super().__new__(mcls, name, bases, namespace) #5: unittest/case.py:574: 103.1 KiB testMethod() #6: Lib/linecache.py:127: 95.4 KiB lines = fp.readlines() #7: urllib/parse.py:476: 71.8 KiB for a in _hexdig for b in _hexdig} #8: <string>:5: 62.0 KiB #9: Lib/_weakrefset.py:37: 60.0 KiB self.data = set() #10: Lib/base64.py:142: 59.8 KiB _b32tab2 = [a + b for a in _b32tab for b in _b32tab] 6220 other: 3602.8 KiB Total allocated size: 5303.1 KiB The getline() is convinient. Sorry for being late, but the need of the new method came when I started to work again on tracemalloc to prepare my conference for Pycon US. ---------- files: tracemalloc_getline.patch keywords: patch messages: 213113 nosy: haypo, larry priority: normal severity: normal status: open title: tracemalloc: add getline() method to Traceback and Frame versions: Python 3.4 Added file: http://bugs.python.org/file34349/tracemalloc_getline.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20888> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
