[gentoo-user] Emerging SVN build when server is down

I've just tried to emerge the svn ebuild of madwifi-ng after a kernel
update. I have previously merged this so I have working sources in
$DISTDIR/svn-src but svn.madwifi.org is down. The emerge bails out when
it is unable to contact the server, when I would prefer it to use the
existing sources. Is there a way to force portage to do this?

If not, I think I should file a bug on this as it is a significant
blocker. After all, if I didn't have a wired connection, the server would
always be unavailable until I remerged the package.

None of the madwifi-ng ebuilds in my portage tree have an svn source.
I'd be surprised if they did because the Gentoo devs generally
discourage subversion/cvs/etc. ebuilds.

Also lots of times a SRC_URI server is down or a mirror is out of sync
and we don't call them bugs; we call them crappy servers.

Now I'm not a Gentoo dev (anymore) but I wouldn't be surprised that if
you submitted a bug you'd get a WONTFIX or a "patches welcomed"
response.

It's in an overlay, the portage ebuilds don't support my card. although
there are ebuilds in portage that use svn/cvs, like MythTV.

Well, that is the root cause of the problem, or they didn't pay their
hosting bill! But it is better to work around such situations than blame
others.

The point is that I already have the sources in $DISTDIR, but portage
won't use them until it can verify that they are up to date. Since they
work and the server doesn't, I'd say that was a reasonable assumption.

I was hoping someone already knew a workaround, otherwise it makes it
impossible to build from source you have already downloaded and verified,
which sounds like a bug to me!

Hm. Edit the ebuild and temporarily disable the up-to-date check?

I have not tried this myself but you can try to copy $DISTDIR/svn-src
to $WORKDIR and use 'ebuild name-of-the-ebuild.ebuild
{install,qmerge}' to install it manually. See 'man ebuild' for
reference.

Maybe you should do 'ebuild name-of-the-ebuild.ebuild unpack' before
so hopefully all other stuff in $WORKDIR is created besides the work
folder itself which fails because of the missing sources. Then copy
the sources manually and run install and qmerge.

Regards,

Daniel

That's all handled by the subversion eclass, and I don't want to mess
with that.

There's an env var, something like ESVN_SERVER, that you can set 
to "offline", and if the ebuild inherits the svn eclass, it won't try 
to checkout new sources.

You'll have to look in the eclass to find the correct name. I looked it 
up only once and noted that it's analogous to ECVS_SERVER (which I use 
often).

Thanks Alan. The variable is ESVN_OFFLINE, which you set to anything
non-empty to skip the updates. I'd hoped portage was intelligent enough
to have a way to use existing svn sources. It is, it's just a user not
intelligent enough to find it :(

Thanks again!

Why is it that when you transport something by car it's called shipment,
but when you transport it by ship it's called cargo?

I was about to try this when Alan's suggestion arrived, which worked.
However, this is just the sort of kludgy approach that appeals to me :)

Yeah, using the env variable is a bit smarter than my approach. ;-)

It may be smarter, but it's also, ho hum, so *ordinary*. I mean, env 
vars are supposed to be read by apps and modify their behaviour 
accordingly. And here I am, offering a solution that merely uses the 
system as designed. How boring....

Elegantly misusing the ebuild command to get the correct result anyway - 
now that is a stroke of pure genius. I shall make a note of this in my 
journal, that my grandchildren, fifty years hence, may still appreciate 
how real men made operating systems back in the day.

:-)

Oh dear, I'm getting verbose again...
