[Kea-users] keama-leases.py fails with abandoned leases

[John Lind]

I managed to pull the script from the GIT repository.  It doesn't seem to
be versioned, but I believe it is the latest and it says:

# dhcp2kea by marmo
# 6-12-2022 (dhcpd4), 14-12-2022 (dhcpd6), 15-12-2022 (dhcp2kea.php)
# 23-12-2022 ("addr key=value" option)

It seems to work great on my "leases" file, EXCEPT for the entries that are
abandoned, e.g.
lease 192.168.1.43 {
        starts 0 2023/12/17 00:15:52 UTC;
        ends 2 2024/01/16 00:15:52 UTC;

        abandoned;
}

Then it says,

root at remo:/home/john/xfer # python3 keama-leases.py dhcpd.leases
Traceback (most recent call last):
  File "/home/john/xfer/keama-leases.py", line 329, in <module>
    print(leases,file=f)  # writing
    ^^^^^^^^^^^^^^^^^^^^
  File "/home/john/xfer/keama-leases.py", line 105, in __str__
    , v["hardware ethernet"] # hwaddr
      ~^^^^^^^^^^^^^^^^^^^^^
KeyError: 'hardware ethernet'

This is not a show stopper for me, because I can just edit out those
half-dozen or so entries and then it seems to work fine (though I haven't
tried importing the .csv file into a mem file - not that far yet - or maybe
this IS the format of the mem file?) but since this is a perfectly
legitimate entry from isc-dhcpd, I'm wondering if a fix might not be in
order?  I'm guessing that it should be fairly simple to test for the
existence of that key and skip the entry, but I'm not a python person (perl
rules!) so I don't feel fully confident in trying to fix this.  If I' the
best available candidate, I'm willing to take a run at it.

Actually, I did just take a swing at it.  It was easy.

root at remo:/home/john/xfer # diff keama-leases.py keama-leases-fix.py
96a97,98
>             if "hardware ethernet" not in v:
>                 continue

Can someone help me commit this to git?
