Hello, pylucene-dev.
I have discovered memory leak. When I use ParallelMultiSearcher then
memory usage is okay.
But when I try to use object of this class under PyLucene.PythonThread
then I receive memory leaks.
Actually size of leak is not big, but when application run for hours
then memory usage is very noticable.
After start:
$ ps aux
500 18732 85.0 13.2 328624 270900 pts/1 S 07:00 0:03
/usr/bin/python2.4 ./RemoteSearchThread.py
After 10 minutes:
$ ps aux
500 18732 94.6 14.9 357556 306592 pts/1 S 07:00 2:08
/usr/bin/python2.4 ./RemoteSearchThread.py
After 20 minutes:
ps aux
500 18732 87.5 16.3 378804 334784 pts/1 S 07:00 4:47
/usr/bin/python2.4 ./RemoteSearchThread.py
It never stops to leaking memory, always consuming.
I have attached example of code to reproduce bug.
Yura Smolsky.
#!/usr/bin/python2.4
from PyLucene import *
from IndexerLucene import *
import threading
class MyThread(PythonThread):
def __init__(self, searcher):
self.searcher = searcher
PythonThread.__init__(self)
def run(self):
a = StandardAnalyzer()
query = QueryParser.parse("bad", "content", a)
hits = searcher.search(query)
del self.searcher
searcher = IndexSearcher("index/index03")
parallel = ParallelMultiSearcher([searcher])
for i in range(10000000):
th = MyThread(parallel)
th.start()
th.join()
