import hashlib crashes sl4a

[GoogleCodeExporter]

What device(s) are you experiencing the problem on?

Nexus S

What firmware version are you running on the device?

2.3 (GRH55)

What steps will reproduce the problem?

The following python program exits without an error message but also without 
executing the 2nd print statement

--------
print "hello"
import hashlib
print "hashlib imported"

What is the expected output? What do you see instead?

Only "hello" is printed.

Please provide any additional information below.

Seeing the same thing on my nexus S running 2.3.

Works fine for me, both in emulator and my HTC Desire.

Just a thought, though: what is the default path for the sdcard on these 
devices?

Mine is /sdcard (or possibly /mnt/sdcard)...
Frank was having trouble running "pydoc", and I see on his traceback that the 
files are being stored on "/storage" ... wonder if python is having trouble 
finding the extras directory? Or if there's a hardcoded "/sdcard" somewhere in 
the source?

You should be able to check:

import os
print os.environ['PYTHONPATH']

Should produce something like:
/mnt/sdcard/com.googlecode.pythonforandroid/extras/python

Check with a file browser to see if the extra libs are in fact installed there.
If not, that may be the problem.

Another thought... hashlib uses a C library.
What processor does the Nexus S use?

I get both printed lines on my Archos 5 Android 1.6.

Robbie's path script shows "/storage/...".

I might not have mentioned it but I don't know Linux. I vaguely recall that 
there are two or three ways to call a mounted volume, depending on the OS. On 
my system /storage and /sdcard are the same. I'm only guessing that /sdcard is 
the existing file which serves as the mounted volume, and that /storage is the 
fictitious name being used as a redirection to that file. I might have this 
backwards though, or perhaps a little sideways. I dearly hope a LUnix guru will 
clarify this. I don't have root so I can learn very little from experimentation.

rjmatthews62, I've confirmed that the PYTHONPATH environment variable looks 
sane and that the Python libs are in fact installed there.

Your follow-up message is closer to the mark, I think.  If you look at the 
stack traces, they're segfaulting within the hashlib library, not failing to 
find some library.  I was going to try recompiling the Python for my phone, but 
the process was a bit involved and I was hoping that someone who already had 
the environment set up (and has a nexus S and/or android 2.3) could give it a 
try instead.

Working on a python version for gingerbread (2.3).
There are some incompatibilities with the dynamic libraries, so things like 
hashlib and urllib2 won't load.
