base32hex support in python?

2010-02-11 Thread Vishal Shetye
Hi,
One of the modules that I am currently working on requires base32hex encoding 
as defined by RFC 4648, section 7.
I checked base64 module which has base32encode/decode functionality but not 
with extended hex alphabet.
Is there a module, currently available, that provides this?

As far as I see, it looks fairly simple to add support for base32hex. It 
differs from the base32 encoding only in the alphabet used. I am willing to 
provide a patch.
Just to note, map01 argument won't be applicable to base32hexdecode as this 
encoding uses both 0 (zero) and O (oh) in its alphabet.

Looking at the section 13 of RFC 4648, I think, adding base32hex support would 
make it conform to RFC 4648.

 As long as you make sure that all decorated functions indeed adhere to
 that assumption there is nothing wrong with it.

Help: Group based synchronize decorator

2009-06-18 Thread Vishal Shetye
I want to synchronize calls using rw locks per 'group' and my implementation is 
similar to
http://code.activestate.com/recipes/465057/
except that I have my own Lock implementation.

All my synchronized functions take 'whatGroup' as param. My lock considers 
'group' while deciding on granting locks through acquire.

What I could come up with is:
- decorator knows(assumes) first param to decorated functions is always 
'whatGroup'
- decorator passes this 'whatGroup' argument to my lock which is used in 
acquire logic.

Is it ok to make such assumptions in decorator?
Any suggestions/alternatives?
