Hi Arife,
I had a quick look at the raw data, and I think we can save a *lot* of space. A comparison tells me that if we convert from gzip to bzip2, we would save something like 25% of the space. This is only 100 Gbyte or so, but nice to have.
I think it's a good idea. We can convert from gzip to bzip2. Few applications that use rawdata need to be changed to use bzip2.
If you agree to use bzip2, I can proceed, and do the change.
I have no principal objections against a switch to bzip2 but it has to be done in a coordinated way: RISwhois depends on raw data !!!
I agree, we should make the software aware of the change _and_ coordinate this carefully with our users, so that their tools don't break either. Henk
Two changes are needed:
1. libbgdump MUST support bzip2 (dynamically, user shouldn't have to worry about it, just pass any filename to bgpdump_open and that routine should do the magic of reading the gzip or bzip file in the correct way).
2. riswhoisd MUST recognise .bz2 as a valid extension for RIS raw data files when searching archive dirs for dumps
Currently, I don't know when I could work on #2, but as it depends on #1 anyhow, I'll first wait for a new libbgpdump to be ready before worrying about riswhois code itself.
Cheers,

:-))
no surprise, NP projects were always data hungry :P
