[gentoo-dev] Overriding/disabling MD5 checksums

[gentoo-dev] Overriding/disabling MD5 checksums

[Dan Armak]

Hi all,

My question got lost in the howto thread, so I'm reposting here.

How can I override checksum checking/generation in an ebuild? Some things 
e.g. the howto ebuilds need this, because they're auto-updated 5 days a week 
and we obviously can't keep checksum lists for all versions. Therefore the 
ebuild should only check that the archive extracts with no errors.

You cannot override the md5 checks.  They exist to ensure archive integrity,
which is a good thing.  Right now, you need to create a new ebuild for each
new package version, as the package version of the ebuild and the actual src
archive should be equivalent.

So do you want me to create a new ebuild 5 days a week? And the end-user 
would have to 'emerge rsync' 5 days a week to emerge the latest version?

Now, we (pm and I) have spoken to the linuxdoc.org guy, and he's agreed to 
make archives with timestamps in their filenames. But, mirrors probably won't 
be keeping more than two or three old versions. So again we need to update 
*something* 5 days/week.

What do you propose?

(Someone should include MD5 checksums as a server-side function in the 
http/ftp protocols. :-)

What I'd like you to do is build a howto ebuild as normal, for the most recent
version currently available, and update it maybe once a month.  If the
linuxdoc.org people don't keep a big archive backlog, you should send the
archive you use to achim so he can add it to ibiblio.org.

I have to go now. I'll read your reply & answer tomorrow. Hopefully we can 
get this issue quickly sorted out.

ibiblio.org is linuxdoc's main d/l site as well as gentoo's.
I can do it two-three times a month, it's no big deal. As long as we decide 
we don't have to always provide the latest version.
If that's what we've decided, OK. I'll d/l the latest tomorrow morning, make 
a checksum and tell achim to copy it to the gentoo dir at ibiblio.org from 
the linuxdoc dir - that's probably fastest.

Yes, that's how we'll do it.  Portage doesn't have the ability to auto-update
ebuilds to the most recent version available (at least not yet), so it's really
our only option (again, right now.)  When I get back to hacking on Portage,
that situation will change.  But until I have the time, we need to do things
within our existing framework and feature set.
