Hi everyone,
I am trying to use imaplib to download messages, but I keep getting
memory errors when I try to download a large message (i.e. one with
attachments). Here is my test code (similar to the example in the
imaplib documentation):
import getpass, imaplib
M = imaplib.IMAP4_SSL("imap.gmail.com")
M.login("[EMAIL PROTECTED]", getpass.getpass())
M.select("[Gmail]/All Mail")
typ, data = M.search(None, 'ALL')
for num in data[0].split():
typ, data = M.fetch(num, '(RFC822)')
print 'Message %s\n%s\n' % (num, data[0][1])
M.close()
M.logout()
And here is the error message:
Python(4521) malloc: *** mmap(size=6389760) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Traceback (most recent call last):

data = self.sslobj.read(size-read)
MemoryError
I am using Mac OS X 10.5 and Python 2.5.1 (downloaded from
python.org). I think it is possible that it is <http://bugs.python.org/
issue1092502>, but the workarounds suggested there do not seem to work
for me. Is this an actual Python bug, or am I doing something wrong?
