Re: python memory leak only in x86 64 linux

[rkmr.em@gmail.com]

This is the code that is causing memory leak in 64 bit python [but not
in 32 bit python].. is something wrong in the code?

now = datetime.dateti me.now()
oneday = datetime.timede lta(days=1)

def birthdaycompare (a, b):
if a is None and b:
return 1
if a and b is None:
return -1
if a is None and b is None:
return 0
if a<b:
return -1
elif a==b:
return 0
else:
return 1

def compare_by(fiel dname):
def comparedict(a,b ):
return birthdaycompare (a[fieldname], b[fieldname])
return comparedict

def getbirthdays(fr iend_details):
new_f = []
birthday = None
birthday_dt = None
for f in friend_details:
if f.has_key('birt hday'):
birthday = f['birthday']
if birthday and birthday !='':
birthday_split = birthday.split( ',')[0]
if birthday_split == 'February 29':
birthday = 'February 28'
try:
birthday_dt =
datetime.dateti me.strptime(bir thday_split + ', ' + str(now.year) , '%B %d, %Y')
if birthday_dt < (now - oneday):
birthday_dt =
datetime.dateti me.strptime(bir thday_split + ', ' + str(now.year+1) ,
'%B %d, %Y')
except:
birthday=None
birthday_dt=Non e

f['birthday'] = birthday
f['birthday_dt'] = birthday_dt
new_f.append(f)
new_f.sort(comp are_by('birthda y_dt'))

the memory usage of a python app keeps growing in a x86 64 linux

i isolated the memory leak problem to a function that uses datetime
