我基本上做了以下工作：
import cProfile, pstats, StringIO
pr = cProfile.Profile()
pr.enable()
# ... my code did something ...
pr.disable()
s = StringIO.StringIO()
sortby = 'cumulative'
ps = pstats.Stats(pr, stream=s).sort_stats(sortby)
ps.dump_stats('stats.dmp') # dump the stats to a file named stats.dmp
所以现在我有一个名为“stats.dmp”的文件离线存储。
我如何使用 pstats 来分析此文件以供人类使用？
提前致谢。
这是我发现的内容以及我生成的 Python 程序。我使用在 Linux 上制作并在 Windows XP 上分析的 .dmp 文件对此进行了测试。效果很好。 Python 文件名为“analyze_dmp.py”。
#!/usr/local/bin/python2.7
# -*- coding: UTF-8 -*-
"""analyze_dmp.py takes the file INFILEPATH [a pstats dump file] Producing OUTFILEPATH [a human readable python profile]
Usage: analyze_dmp.py INFILEPATH OUTFILEPATH
Example: analyze_dmp.py stats.dmp stats.log
