Sounds good, unless this introduces serious bugs or security issues.

If there’s a test log excerpt that would be worth adding in this
comment, that’s even better.  Otherwise go for it!

Great work!  Thanks for taking the time to look at all the details (SSE,

Hopefully Lua and zstd would be easy to address, but yeah, we can leave

Yes, it's on my priority list, but figured it's better to have it
available so that others can use it and help out. I keep picking this up
every few weeks, but the build takes hours and so it's very tiring work.

(also, poor Hydra!)

The TODO list is:

* make `ceph-disk` work for the tests (it works when installed)
* make it build on ARM (apparently libaio is unsupported there)
* unbundle more things
* services! (I need more hardware first though :-))

I'm committed to supporting this package, so please ping me about any
problems (in Guix, or on your test cluster ;-))

Also, I just built this to verify that it still works, but got two
different test failures on two different machines, suggesting some tests
are flaky. Perhaps I should just disable these two off the bat?

Nevermind, it was two very rare race conditions (one that only seems to
occur with -j16 and slow storage). Let's deal with them if it they turn
out to be not so rare.

Maybe best to disable them, yes.

Would be worth checking how this affects the closure size.  It’s a
developer tool though, so I’d argue that it’s less of a problem if the
closure size is increased noticeably in this cases.

Otherwise LGTM, thanks!

ceph:lib increases fios closure size from 452.3 MiB to a good 738 MiB.

However, by moving the fio auxiliary scripts to a separate output, I
managed to get the baseline size down from 452.3 MiB to 75.3 MiB. See
attached patch. WDYT?

Add a comment explaining that this saves X MiB on the closure.

Maybe s/utils/bin/ if there aren’t any other binaries, otherwise LGTM!

It’s a case where it’d be enough to put lgpl2.1+ and gpl3+ IMO, since
that’s what effectively applies to the resulting work.

You could still mention the other licenses in the comment though.

Otherwise LGTM, thanks!

Is this also true for the source code archive itself? As an end user,
looking at the license list and deciding to `guix build -S`, I would
expect the contents to match what's in the package definition.

Is this a distinction we should make? I.e. "source" license vs "product"
license. For Ceph, this would be the current license list in the first
instance and just lgpl2.1 and gpl2 for the built product.

Tricky! Moving the other licenses to the comments for this package, but
something to think about.

Thinking more about this, the "output license" for Ceph would include
BSD-{2,3} as well (some erasure code stuff), but you catch my drift.

It makes sense to focus on the license you accept by using the package,
and mention whatever other source licenses that may be present as
source code comments instead.

Sorry for spamming this discussion, but it's something that I haven't
seen discussed before and it's good to clarify a few of these points.

Ceph is also a prime example of a complex package covering lots of
licenses. Some of the ".so" files installed by Ceph are produced by
BSD-style code. However, they link to the main ceph libraries, which are
LGPL2.1. IIUC, LGPL2.1 "trumps" BSD here because of the strong copyleft.

Ceph also installs some erasure code ".so" files that do *not* link
against Ceph (as verified with readelf and ldd). They are covered by a
BSD-style license. These should then be mentioned separately, methinks,
because they are installed by this package and used by some of the
(L)GPL code.

Most of the Python libraries in Ceph are actually LGPL2.1+. These use
the main Ceph libraries, which are LGPL2.1 (no plus). AFAIU, the latter
still "wins", or should LGPL2.1+ be mentioned separately?

Please correct me if I'm wrong in any of these assumptions :-)

Perhaps the manual could be improved with a few clarification points,
although it's a complex issue that will vary on a case-by-case basis.

Right, copyleft licenses “win” over the non-copyleft ones.

Yes, that makes sense to me.

I’d mention just LGPL2.1 since it “wins” over LGPL2.1+, but with a
comment explaining the situation.

(There’ll be a lot to read in that file! :-))

Indeed!  We also need clarifications on when to use “+” on GNU licenses,
since it’s never obvious to newcomers.

Thanks,

The intent was that ‘license’ would be the license that applies to the
combined work (the thing that you install), IOW the license that “wins”,
omitting build-time programs like ‘install-sh’ and similar scripts.

This is similar to what the Free Software Directory does but coarser
than what Debian does, for instance.

However that has always been under-specified, and a number of packages
list all the licenses that apply to various parts of the source, as you
did above.

Yeah, tricky!

This already exists as liburcu in datastructures.scm (I needed it for
the Knot DNS server), with two main differences:

Building liburcu with ‘perl’ or ‘perl-test-harness’ gives the same
result (Files=3, Tests=78). I know nothing about Perl. Is there a reason
to prefer ‘perl-test-harness’? It's about .5 MiB heavier.

Wow. As usual you're a lot better at sniffing out licences than I am.

I also prefer your ‘synopsis’ to mine.

I don't know either, I just searched around for the `prove` command and
found it was in "perl-test-harness". Apparently it's in "perl" too!

Ha, but at least you got it right (per the other discussion on this
thread) ;-)

I can update the synopsis of the existing package, and add @code{}
wrappers to your arguably better description; as well as adding comments
about the other licenses. How does that sound? :)

That sounds about perfect.

  $ grep gpg .thunderbird/*/prefs.js

Oof. Can't blame your cat this time. Is anyone else seeing a bad
signature for id:cdd6892d-5182-ee07-7452-8df83136e3d0@tobias.gr ?

Are you able to reproduce the bad git signatures with GPG from Guix?

Maybe it is the cat after all.

Oh! I didn't mean to send you on the beginnings of a bug hunt. Turn
back. Trust me.

Yes, my gnupg's definitely dodgy, and it really is from Guix . I've gone
so far as to rm -rf /usr/bin/gpg* — no dice. I'm pretty sure it's
somehow caused by the unique... let's call it ‘legacy-rich’ Ubuntu
installation on this work laptop. It doesn't happen anywhere else.

However: that laptop has less than one month left as Important Work
Machine. Guess what's happening next? GuixSD is happening next.

Until then, I'm just going to ignore its quirks and live with the shame
(and not push any commits from this box, hook or no). I'll make sure
anything important's signed.

> Maybe it is the cat after all.

My cat is pure evil. I'm pretty sure she uses Windows.

Ok, good to know. It could be worth testing the memory. I guess we'll
find out after you've migrated to an entropy-free system :-)
