[Chicken-hackers] [PATCH(5)] Teach Henrietta about major releases

[Peter Bex]

Hi all,

Here are a handful of patches to make CHICKEN 5 eggs installable:

The henrietta.patch applies to Henrietta trunk, which lives in SVN.
I decided to put it on this list for consideration, so we all know what's
happening with the infrastructure, and after all it does apply to the
new core developments.  It is just a proposal, but I think this patch
will make things much easier further down the road.

When trying to update CHICKEN and Henrietta so that chicken-install can
pass the major CHICKEN release to Henrietta, I noticed that they are
strangely intertwined: henrietta calls into the same API that
chicken-install uses.  Basically henrietta uses the "local" transport
which chicken-install would normally use on the server, but then serves
up the results over HTTP to the chicken-install running on the client
machine.  This is needlessly cyclic and complicated: it's simply reading
a directory!

The old henrietta used to be able to serve over svn too, but we don't
use that anymore since the SYSTEM has gone live, so I think it's safe
to simplify henrietta by copying all the "local transport" code from
setup-download into, and removing the dependency on core.  This allows
us to freely rewrite chicken-install (if we ever want to) without having
to worry about whether it will break Henrietta.

I've also removed the now-pointless "tags" subdirectory: this makes the
directory layout somewhat flatter and simpler.  The cache would look
like this:
/var/www/henrietta-cache/4/easyffi/1.0
/var/www/henrietta-cache/4/easyffi/2.0
/var/www/henrietta-cache/4/spiffy/1.0
/var/www/henrietta-cache/4/spiffy/1.1
...
/var/www/henrietta-cache/5/spiffy/2.0
/var/www/henrietta-cache/5/srfi-18/1.0

This will require a small change in henrietta-cache as well, of course,
so it won't try to include a "tags" directory in the path.

Now, on to the core patches!

The first core patch removes support for Subversion from setup-download.
It is not needed at all and needlessly complicates things.  The special
status of svn in our infrastructure is mostly gone, and if you want to
install a particular egg from svn, it's not much of a hassle to make a
checkout first.  Of course, this patch is optional; if you disagree feel
free not to push it.

The second core patch adds the "release" argument to the query string
which the new version of Henrietta will parse.

Once everything is pushed, I'll see to it that henrietta-cache gets
updated and will set up the whole thing on the call-cc.org server
together with Mario.  After a short testing period, I'll ping Alaric
about updating his server, too.

Cheers,
Peter
