[Buildroot] [PATCH v2 1/2] package/mosquitto: bump to v1.6.11

[Titouan Christophe]

Mosquitto 1.6.11 is a bugfix release, read the whole announcement on
http://mosquitto.org/blog/2020/08/version-1-6-11-released/

From the changelog of the client library:
mosquitto_loop_start() now sets a thread name on Linux, FreeBSD, NetBSD,
and OpenBSD. Closes #1777.
This is done with pthread_setname_np; so mosquitto now requires
BR2_TOOLCHAIN_HAS_THREADS_NPTL when built with threading support.

Changes v1 -> v2:
* Only depend on NPTL when compiling with threading support, introduce
  BR2_PACKAGE_MOSQUITTO_WITH_THREADING

[Buildroot] [PATCH v2 2/2] package/{collectd, domoticz, shairport-sync}: fix mosquitto dependencies

[Titouan Christophe]

In 4fc62e1eb6b3adbfc3d3eb7f841275ae8cd1b424, we removed arch/toolchain
dependencies from the mosquitto library (MMU, !STATIC, SYNC4), and moved
them to the mosquitto broker only.

All the packages modified here only need the mosquitto library, so they
shouldn't have those depends anymore; but this was never done before.

Moreover, domoticz and shairport-sync both use the mosquitto threaded
API, so we make them dependent on the newly introduced symbol
BR2_PACKAGE_MOSQUITTO_WITH_THREADING.

This looks awkward. Why are you not just doing:

-ifeq ($(BR2_TOOLCHAIN_HAS_THREADS),y)
+ifeq ($(BR2_TOOLCHAIN_HAS_THREADS_NPTL),y)
 MOSQUITTO_MAKE_OPTS += WITH_THREADING=yes
 else
 MOSQUITTO_MAKE_OPTS += WITH_THREADING=no

in the .mk file ?

I think this mixes two different things. One is dropping the
dependencies that are no longer needed following
4fc62e1eb6b3adbfc3d3eb7f841275ae8cd1b424. This should be the first
patch in the series.

Also, regarding the threading, nothing needs to be done: both
shairport-sync and domoticz already have a dependency on
BR2_TOOLCHAIN_HAS_THREADS_NPTL. The only thing that could be worthwhile
doing, is *within* the 1.6.11 version bump patch, update the
BR2_TOOLCHAIN_HAS_THREADS_NPTL comments in domoticz and shairport-sync
packages. Like:

-  	# pthread_condattr_setclock
+	# pthread_condattr_setclock, and threading support needed in
+	# mosquitto
  	depends on BR2_TOOLCHAIN_HAS_THREADS_NPTL

and something similar for shairport-sync.

Thanks!

Thomas

The underlying idea was to "provide a config option for a package to 
depend on, if it uses the mosquitto threading API" which might indeed 
sound overkill. Plus I did not pay attention that HAS_THREADS_NPTL 
implies HAS_THREADS.

Yes, I'll do jut that
