'name' can't be retrieved using getattr, always returns empty string #198

Seems that 'name' is actually a specially reserved attribute, or conflicts with the internal JS object representation somehow. Trying to retrieve it with getattr always returns the empty string. Here's the sample code:

class TestClass(object):

def __init__( self ):

    self.name = 'foo'

test_class = TestClass()
my_name = getattr( test_class, 'name' )
print "my_name is: " + my_name
print "no, actually it is: " + test_class.name

Which pyjamas version are you using and what are the compile options?
Which browser (if any)?

I get the following output:
my_name is: foo
no, actually it is: foo

I'm using the git head, I've reproduced the issue on a separate machine. Here's the last commit:

Oh, I was just using regular pyjsbuild with no args. Though generally I try to use --strict.

I've tried with several options. I still can't reproduce this.

What I've tried:
rm output/lib/.js; ./pyjsbuild --no-compile-inplace -O --print test_getattr.py
rm output/lib/
.js; ./pyjsbuild --no-compile-inplace test_getattr.py
rm output/lib/*.js; ./pyjsbuild --no-compile-inplace --strict test_getattr.py

So, it should also work without --strict option. If you could provide more details to get to this problem, that s appreciated. (E.g. the test_getattr.js that's generated, assuming that you name your test file also test_getattr.py ;-) )

Which browser do you use?

I was able to reproduce this with chrome.

This bug should be fixed (commit c06a123)

I'll close this ticket, unless you still see the problem.

apologies, kees - LibTest doesn't run (throws an exception with "CompileTest" no attribute named prototype) so i had to back this out (attached)
