Danek?
I know that package have many files in opensolaris IPS .and every
file's name is the same to its sha1sum hex value.
file c41696164a53a1c4ee38acbc7593a9a0b9d4fce5
chash=a37ea1a7157fe2565e9b6221b07724e4d75929da elfarch=i386 elfbits=32
elfhash=48aff52a291dfdefa86b92d12f1d3a9394067f53 group=bin mode=0555 owner=root
path=usr/bin/ipcrm pkg.csize=5217 pkg.size=13444
I know how to compute csize and chash with my method(I don't know if it is
right).
my result is the same with above mention.
But some file like:
grub's splash.xpm.gz
file 8ccd759e9fdb0bbae20aa259e9fe35c536ee8bda
chash=ff984d5e01af0caf4252438cccb18ecbb21f21c1 group=sys mode=0644 owner=root
path=boot/grub/splash.xpm.gz pkg.csize=47363 pkg.size=47330
I know shasunw value 8ccd759e9fdb0bbae20aa259e9fe35c536ee8bda is a file
name,file's orignal name is splash.xpm.gz .that's to say
splash.xpm.gz 's sha1sum is 8ccd759e9fdb0bbae20aa259e9fe35c536ee8bda .Then I
get a wrong result ,it's not chash=ff984d5e01af0caf4252438cccb18ecbb21f21c1 .
So I want to know the detail arithmetic and compute steps.
Thanks,

chash and csize are the hash and size of the gzip-compressed file as it
comes over the wire. This lets us verify the hash of the file on the
client without having to uncompress it, and it lets us have a more accurate
download meter than if we were to use the uncompressed size.
