perl binding for rados ?

perl binding for rados ?

[Lalit Kumar Bhasin]

Hi,

Is there any perl bindings available for rados, or be available in near 
furture? I can't find it on cpan. As of now, only way I can see is to 
use librados through perl-XS interface.

All I can give you is a past discussion thread:

Marcus, did you get anywhere with these?

Admittedly they kind of dropped off my radar after it didn't seem to
Garner much interest. I do however have some code that seems to work
for connecting, listing pools and devices, basic adding and removing.
I dont have all of the functions wrapped but at this point I feel like
it's mainly just a matter of copying what's already there to fill in
the rest. It uses inline::c . I would be happy to tar up what I have
and make it available if someone wants to build on ot

Here is the package, just tested against 0.38. There are perl
subroutines at the top of RADOS.pm, which call the native C functions
below. Inline::C handles the conversion of datatypes, you should be
able to look at what's already done for the most part to fill out the
rest of the routines.

As far as known issues, the cluster_stat throws a failed assertion
with a brand new cluster, if I comment out the stat lines in my test
script, run the script once, and then uncomment everything is fine
from then on. Have not troubleshot it at all, it might be on the C
side with rados_cluster_stat or perhaps it's returning something
unexpected.

./common/Mutex.h: In function 'void Mutex::Lock(bool)', in thread '7fc0e2c2a720'
./common/Mutex.h: 110: FAILED assert(r == 0)
 ceph version 0.38 (commit:b600ec2ac7c0f2e508720f8e8bb87c3db15509b9)

 9: (main()+0xec) [0x400ccc]
 10: (__libc_start_main()+0xff) [0x7fc0e1cabeff]
 11: perl() [0x400af9]


 Also in general some extra validation,etc is a good idea, I was just
writing things and seeing if they worked. testrados2.pl does the
following:

connects to monitor
stats cluster
creates a pool
lists pools
opens a pool
gets the pool id
gets the pool auid
sets the pool auid
closes the pool
deletes the pool
disconnects

I hope this is useful to someone so they don't have to start from
scratch. What follows is the test procedure I performed this morning.
