Hi all,

One for discussion, I'm sure. :-)

There hasn't been a uClibc release since May 2012, but some useful things have
landed in git since then... for example, make/get/setcontext are necessary for
uClibc + gccgo/libgo (c.f. my last patch set).

This adds a non-default option for a known-good nightly snapshot. I'm sure you
will have comments on some of the... hmm... odd things I've done. Let me know!

I suspect the nightly snapshot tarballs will disappear (it looks like they're
rolled over after a couple of weeks), so it might be best to change this to a
git checkout. But I did it this way to get it ready for feedback.

Thanks,
Jeff

adding uclibc snapshots maybe other (patched) variants 
might improve .... well some things (quality ? pressure to release new stable version?)

uclibc version "problems" affect other uclibc users too [0],[1],[2]
and this came up regularly in the past and its a little bit messy
to have potentially slightly different uclibc versions between projects
[3][4] (hoping that these are the correct uclibc patch/variants links for buildroot
and yocto project)

Its probably a good thing to get easier access to a uclibc variant than using 
- "abandoned" eglibc = bad ("EGLIBC is no longer developed and such goals 
  are now being addressed directly in GLIBC. ")
- musl ("experimental")

By the way, I've also been working on a patch to re-introduce glibc. I'll
send that through soon. :-)

So we have some options:

1) use uclibc-snapshot.tar.bz2 instead of a dated, known working version
(though we can't check the md5sum)
2) use uclibc git at a specific revision
3) use uclibc git at head
4) anything I don't know about? uclibc-ng?

I'm leaning towards (2) at this point, and will send through a patch for
that.

It's a pity that (1) is just *so* easy. And although it won't produce
like-for-like builds from a fresh checkout of OpenWrt, if you've already
downloaded the snapshot tarballs then your own builds will be
like-for-like. At least in that context.

Option 1) may seem easy in the short term, but it gets messed up so
easily. We also have a policy to not have any moving-target packages in
the same way, so I'm even less inclined to accept it for a libc.
Same issue with 3).
Integrating a uclibc fork like -ng is probably also a waste of time.

Did you see any real improvements with the snapshot that you used in
your patch?

FWIW, I consider uClibc a dead end for OpenWrt. After the CC release is
done, I want to push for switching to musl by default and fix the
remaining issues with that.
Unlike uclibc, musl has decent code and an active maintainer and
developer community.
Unlike glibc, musl is quite small - actually comparable in size to uClibc.

In terms of performance, I expect musl to beat both glibc and uClibc.

The main thing for me was presence of get/set/makecontext support.
Definitely agree about the moving target problem.

Alrighty, that makes sense. Thanks for your feedback.

I'll probably leave further work on musl vs. gccgo/libc to someone else,
and focus on making sure it's nicely integrated at least with glibc.

Thanks,
Jeff
