npyio.py --> recfromcsv seems to have a bug and ignores any dtypes provided (Trac #2168) #5958

Original ticket http://projects.scipy.org/numpy/ticket/2168 on 2012-06-16 by trac user kobejohn, assigned to unknown.

I found this due to someone having a problem not being able to load large integers with recfromcsv. After playing with it, I think it is simply ignoring all the dtype information provided.

[https://github.com/numpy/numpy/blob/master/numpy/lib/npyio.py#L1859 Line 1859 in npyio.py, part of recfromcsv()] tries to either bring in the dtypes passed or set None. However, it actually brings in a kwarg that I couldn't find anywhere else called 'update' which looks suspiciously like a copied mistype from earlier in the line.

If I change 'update' --> 'dtype', then the types get picked up as expected.

I found this in the github repo (although I may have been looking at the wrong branch) as well as 1.6.2

Please delete this ticket if possible. Someone notified me that the project is trying to work on github now so I posted this there. Sorry for the trouble.
