Hello Guix,

Attached is a patch for the c/c++ version of msgpack.  This is a
dependency of the Ring.

Thank you!

LGTM. Waiting on a response to some questions about the 'googletest'
dependency.

I noticed that the output does not refer to zlib:

$ guix gc --references $(./pre-inst-env guix build msgpack)
/gnu/store/8m00x5x8ykmar27s9248cmhnkdb2n54a-glibc-2.22
/gnu/store/jh52sklgbvq5f0z637wr99a64y25cx8r-msgpack-1.4.1
/gnu/store/v39bh3ln3ncnzhyw0kd12d46kww9747v-gcc-4.9.3-lib

However, the compilation fails without it.

We need to make sure that msgpack can find zlib at run time. Lukas, can
you check if there is a build-time configuration option to provide the
path to zlib?

This is from the top of the msgpack source tree:
$ grep -rI zlib
include/msgpack/zbuffer.h:#include <zlib.h>
include/msgpack/zbuffer.hpp:#include <zlib.h>

Should we do string substitution to provide the abolute path to the zlib
headers?

Hi,

I am sorry for the long silence, this week was busy and I did not find a
lot of time to look into this.  My apologies for that!

Indeed.  I was not aware of this '--references' before.

Specifically, the phase that fails is 'check'.  The phase 'build' passes.

This is probably not necessary, since it can find zlib (at compile time)
if zlib is provided as an input, i.e. all phases pass in this case.  I
think the reason for the missing reference is another:

I did:

$ grep -ri "Zlib" .
./include/msgpack/zbuffer.hpp:#include <zlib.h>
./include/msgpack/zbuffer.h:#include <zlib.h>
./CMakeLists.txt:FIND_PACKAGE (ZLIB)
./CMakeLists.txt:IF (GTEST_FOUND AND ZLIB_FOUND AND THREADS_FOUND)
./test/CMakeLists.txt:FIND_PACKAGE (ZLIB REQUIRED)
./test/CMakeLists.txt:    ${ZLIB_INCLUDE_DIRS}
./test/CMakeLists.txt:        ${ZLIB_LIBRARIES}


Cmake is also supported as build system.  I looked into ./CMakeLists.txt
in the top of the source tree and this is the passage that refers to
zlib:


FIND_PACKAGE (GTest)
FIND_PACKAGE (ZLIB)
FIND_PACKAGE (Threads)
IF (GTEST_FOUND AND ZLIB_FOUND AND THREADS_FOUND)
    OPTION (MSGPACK_BUILD_TESTS "Build msgpack tests." ON)
ENDIF ()


It seems that zlib is only required for tests.  In README and README.md
zlib is never  mentioned among the dependencies, which also supports
that it is only needed for tests.  I was not aware of that before (Shame
on me).

I moved zlib from inputs to native-inputs.  An updated patch is
attached.

Sorry for the confusion and thank you very much for your work on this!

Best,
Lukas

Is zlib really only required for tests? I see this:

$ grep -rIi zlib /gnu/store/xn8z7k6j7zm4qz14bm29fgk0kwwvz3c4-msgpack-1.4.1
/gnu/store/xn8z7k6j7zm4qz14bm29fgk0kwwvz3c4-msgpack-1.4.1/include/msgpack/zbuffer.h:#include <zlib.h>
/gnu/store/xn8z7k6j7zm4qz14bm29fgk0kwwvz3c4-msgpack-1.4.1/include/msgpack/zbuffer.hpp:#include <zlib.h>

So, there are headers in the msgpack output that require zlib.

If you are at the stage where you are using Ring based on these
packages, I wonder if it is not using the part of msgpack that uses
zlib? Or, if it's finding zlib in the environment (if you are on a
foreign distro)?

Or have I misunderstood?

Oh, that is true.  I searched around, but I could not find anything
about zbuffer.h[pp].  I am not sure what it is used for.  FWIW, it is
only referenced in src/Makefile, src/Makefile.in, src/Makefile.am
CMakeLists.txt and in the tests:

Judging from this, I am inclined to think that msgpack does not use
these two headers for anything but tests.  But I am not sure about
this.

I am on GuixSD, but I do not have any packages besides opendht that
would depend on msgpack, yet.  I do not have a working definition for
Ring.  At this point, I do not see any way I could really test if
msgpack works properly with/without zlib.

FWIW, I looked at what other distributions do:

The Arch PKGBUILD does not refer to Zlib at all:
https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/msgpack-c

Gentoo has Zlib for tests:
https://gitweb.gentoo.org/repo/gentoo.git/tree/dev-libs/msgpack/msgpack-1.1.0.ebuild

Debian seems to not refer to Zlib:
https://packages.debian.org/jessie/libmsgpackc2
https://packages.debian.org/jessie/libmsgpack3
https://packages.debian.org/jessie/libmsgpack-dev

This Nix expression does not mention zlib:
https://github.com/NixOS/nixpkgs/blob/f199be0fafcff0713dd4340b4373e575294aad58/pkgs/development/libraries/libmsgpack/generic.nix#L41


However, all of these seem to be different versions of msgpack.


On one hand, since these distributions seem to not include zlib as a
dependency, maybe zbuffer.h and zbuffer.hpp are not meant to be used or are
seldom used by other projects.  On the other hand msgpack installs these
headers, so they should be useful.

>
> Or have I misunderstood?

No, I missed that.  My mistake.  But I am not sure what to do about
this.

I am working on packaging pjproject now.  After that I think I will have
most of the dependencies of libring.  At that point I could probably
test if msgpack works the way it is now.  I am perfectly fine if we wait
with the inclusion of msgpack until then. What do you think?

Best,
Lukas

I think that another application would call the zbuffer functions,
although the string 'zbuffer' does not exist in the opendht source code.
But, we should make sure msgpack will work for other calling
applications that might be added later.

On #guix, bavier suggested we patch 'msgpack.pc.in'. Specifically, we
should append the include flag to 'Cflags:' and create a 'Libs.private:'
field for the -L and -l flags. There are some examples in
'gnu/packages'.

More details on the IRC log:
https://gnunet.org/bot/log/guix/2016-06-13#T1056507

I've cc-ed Eric since I don't know much about pkg-config.

I think that zlib is so ubiquitous that it's a safe assumption it will
can be found in the environment on the '/usr' distros.

An oversight? I don't know the Nix equivalent of `guix refresh -l` to
check which of their packages use msgpack.

OK, I agree.

Neither do I. 

I have experimented with this a bit.  IIUC, since our zlib provides a
pkg-config file we can generate the the -I flag by adding

---8<--- cut here -------------------- start --->8---
Requires.private: zlib
---8<--- cut here -------------------- end ----->8---

to the msgpack.pc.in file.  This also gives me the -L flag. The -l flag
is only emitted when --static is passed to pkg-config.  I tried to fix
this by adding -lz to Libs.private resulting in:

---8<--- cut here -------------------- start --->8---
lukas@serenity$ guix environment msgpack

So I still only get the -lz flag for static linking.  I am not sure if
this is what we want, what do you think?

Also, still no store refernece. BTW, where is "guix gc --references"
implemented?  I looked for it but failed to find the actual logic, since
I am not that fluent with Scheme...

From this I think that adding the -lz to Libs.private is redundant if
zlib is in "Requires.private".  But if we want -lz also for dynamic
linking then I think we need to move zlib to "Requires".  I went ahead
and tried that leading to this result:

So the flags -I, -L, -l for zlib are all there for both dynamic and
static linking.  But still no store reference.

A patch for this last case is attached.

IIUC, zlib has to be a propagated input in this case.  Do you agree with
that?

More general, do you think what I did makes sense?  I am not really sure
if -lz is needed for dynamic linking or not.

Also, is it OK to do things like that in a snippet as in the attached
patch?

Thank you for your help!

Best,
Lukas

I think the reason why there is no reference is that msgpack uses
zbuffer only for tests.  Before compilation, the file only references
the name "zlib" and does not mention the hash in the path of zlib in the
store.  During compilation (during "check"), this mere name "zlib" gets
somehow resolved to the path of zlib in the store.  The binary file
resulting from compiling zbuffer should therefore contain a reference to
zlib, which should be detectable by guix gc --references.  I think
however, that this binary file does not get installed as it is only used
for tests.  All the files that do get installed in the output path of
msgpack in the store do not contain the hash part of the store-path of
zlib.  They only refer to zlib by name.  IIUC this can not be detected
by guix gc --references since it only searches for the hash part of
the store-path of zlib.

This is what I grasp from looking at libstore/references.cc and
libstore/store-api.cc.  I am not sure about this though.

Best,
Lukas

That's my understanding as well.

Thanks for trying all the things you described in your previous email.

Since we are still stuck on this, I think we should continue with Ring
and see if this becomes a problem later on. If so, let's contact the
msgpack maintainers and ask for advice.

We should add a caveat in a comment in msgpack's package definition, for
future readers.

I'm curious — how close are you to a Ring package definition?

Sorry for the late reply, but…

What kind of files are these, and how do they refer to zlib exactly?

(I’m curious, but this shouldn’t block the process, as Leo wrote.)

Thanks,
Ludo’.

It is a C Header file and a corresponding C++ Header file
(include/msgpack/zbuffer.h[pp]).  They refer to zlib by just doing:

#include <zlib.h>

These two files do get installed in the store, but their compiled
counterparts do not.



Thinking out loud, we could possibly force the creation of a reference to
zlib by putting the path of the zlib used when building the package into
a comment or a seperate file.
On the other hand, I am not so sure if we really want a reference, since,
as you said, they are for run-time dependencies.  Since msgpack itself
does not use zbuffer at run-time (only at build time for tests) and does
not provide a library including zbuffer for other packages to link
against, the files zbuffer.h[pp] are really not used at run-time.  The
only time that I can think of when these files could be used is during
the build of a dependent package that wants to include these files.
Propagating zlib would assure that zlib is available whenever
zbuffer.h[pp] gets included by some other package.  Maybe this is the
right way to represent the situation?

Best,
Lukas

Yes, packaging Ring is taking longer than I expected (on my side that
is).  I will send a detailed update within the next two hours.

Thank you for all your work on this.  I would have never even noticed
that issue!  Thank you!

OK, this is a justification for putting zlib in ‘propagated-inputs’
rather than ‘inputs’ (the manual mentions this as one of the valid
justifications for ‘propagated-inputs’ (info "(guix) package Reference")).
It is worth adding a margin comment with this explanation.

It is.  :-)

According to
https://tuleap.ring.cx/plugins/mediawiki/wiki/ring/index.php/Build_Instructions,
Ring is divided into three Layers:
 * Libring (or ring-daemon)
 * LibringClient
 * Clints

I have a work-in-progress definition for libring, I have not started
working on the other layers yet.  I will clean up the wip-patches that I
have and send them them later today.

At the moment I am still tracking down (i.e. unbundling) dependencies
for libring.  At the moment I am working on pjptoject which is one of
the "main" dependencies according to this:
https://ring.cx/en/about/technical#Libraries

There are some more dependencies that might be needed, that I noticed
when looking at librings contrib directory.  This inputs field reflects
all the dependencies from libring's contrib:

      (inputs
       `(("ffmpeg" ,ffmpeg)
         ("flac" ,flac)
         ("libgcrypt" ,libgcrypt)
         ("gmp" ,gmp)
        ; ("gnutls" ,gnutls) ; Maybe not needed as already used by inputs
         ("libgpg-error" ,libgpg-error)
        ; ("gsm" ,gsm)  ; not found
         ("libiax2" ,libiax2)
         ("libiconv" ,libiconv)
         ("jack" ,jack-1)
        ; ("json-c" ,json-c) ; not found
        ; ("msgpack" ,msgpack) ; maybe not needed as used by inputs (opendht)
        ; ("nettle" ,nettle) ; maybe not needed (only certain proprietary OSes?)

         ("pcre" ,pcre)

         ("speex" ,speex)
        ; ("speexdsp" ,speexdsp)
         ("libupnp" ,libupnp)
        ; ("uuid" ,uuid) ; not found, maybe not needed (only certain proprietary OSes?)
         ("libvorbis" ,libvorbis)
         ("libvpx" ,libvpx)
         ("libx264" ,libx264)
        ; ("yaml-cpp" ,yaml-cpp) ;not found
         ("zlib" ,zlib))) ; maybe not needed as used by inputs


Sorry for the format, I will send a real patch later today.  The ones
that are commented above have some issue that needs to be resolved.

I don't really have a lot of time to work on this so progress has been
slow.  Sorry for that.

As I said I will post two patches later (pjproject & libring).  Any help
on those or some of the missing inputs is of course greatly appreciated!


Sorry for the delay!
Best,
Lukas

I didn't mean to make you feel rushed. I was just curious :)

Thank *you* for working on it, too!

try util-linux for this one

there's a libyaml in web.scm. not exactly yaml-cpp in name, but it might
be close enough

Here they are!


pjproject still fails to build one of its components (pjmedia) because
of a missing include (resamplesubs.h).  I almost have a package
providing that header.

I am not super happy with the fact that this is a special package
dedicated to libring.  There are a lot of patches that ship with
libring's bundeled version of pjproject.  These patches are nice
(e.g. gnutls instead of openssl), but they fail on the most recent
release 2.5.1 of pjproject and I have no idea in what way they affect
other software that might want to use pjproject (I think Asterisk would
be an example of this).  I will try to remove some of the constraints on
pjproject that are imposed by libring without breaking anything, but
first I want to get it to build and we might end up needing another
seperate definition for a "normal" pjproject.


The patch for libring is mostly just to keep track of dependencies right
now; it fails during 'configure (when it is looking for pjproject :-))


Any comments are very much appreciated!

Thank you!
Best,
Lukas

+From 5cb3786d107bdea372ab45e6c35f882fd867d5e0 Mon Sep 17 00:00:00 2001
+From: Vittorio Giovara <vittorio.giovara@savoirfairelinux.com>
+Date: Mon, 9 Jun 2014 14:20:55 -0400
+Subject: [PATCH 1/1] ssl_sock: add gnutls backend
+
+This backend is mutually exclusive with the OpenSSL one, but completely
+compatible, and conformant to the PJSIP API. Also avoids any license issues
+when linking statically.
+
+The configure script is updated to select either OpenSSL or GnuTLS
+with --enable-ssl[='...'] and a new symbol (PJ_HAS_TLS_SOCK) is introduced
+to identify which backend is in use.
+
+Written by
+Vittorio Giovara <vittorio.giovara@savoirfairelinux.com>
+Philippe Proulx <philippe.proulx@savoirfairelinux.com> and
+Adrien Béraud <adrien.beraud@savoirfairelinux.com>
+on behalf of Savoir-Faire Linux.

This one is actually a typo and a mistake on my part.  This is supposed
to be jsoncpp.  But I recently changed to the commit tagged with the
latest version number and it seems this is not needed anymore/yet.

This looks good on first glance.  I will need to look into this more.

I have not investigated this much yet, but I think these are different.
FWIW, they are mentioned seperately in
https://en.wikipedia.org/wiki/YAML#Implementations
I will have a look at this.

I think it's fine and I pushed as d1ef573de. If we need to change it for
libring, we'll do that. Thanks!
