[wangye360]

demo code:

---

import os import psutil import ahocorasick

def build_automaton(): automation = ahocorasick.Automaton() for i in range(2000000): automation.exists(str(i))

def show_used_memory(): print('memory used: {} M'.format(psutil.Process(os.getpid()).memory_info().rss / (1024. ** 2)))

if name == 'main': build_automaton() show_used_memory()

build_automaton()
show_used_memory()

build_automaton()
show_used_memory()

---

for python2, result: memory used: 162.6875 M memory used: 255.78125 M memory used: 348.8828125 M

for python3, result: memory used: 10.23046875 M memory used: 10.26171875 M memory used: 10.26171875 M

Thank you for the report.

any plans to fix this?

[stemon]

i have the same problem.

[WojciechMula]

@eddy-avanan Not at that moment, but I'll try to look at this issue. It seems to be a regression, as we already had similar problem and it was solved.

Any updates on memory leak issue for python 2?

@galanamanj could you try to run the tests listed in the release-checklist.txt file on your Python 2 installation? In particular the valgrind tests.

Actual help to track (and fix) these would be mucho welcomed!

I am closing for lack of activity. Please reopen if you feel strongly about it, though Python 2 really fell out of fashion these days ;)
