This is a minor bugfix release that addresses some problems identified during Debian packaging.
The MQTT protocol is going for standardisation at OASIS. A technical committee is being formed and there is a call for participation for interested parties. There are details at the link below:
The plan seems to be to take the 3.1 spec as it is for standardisation and see about changes in the future. If you are interested in taking part see the link above, but note that you need to be a paid up member of OASIS.
This is a bugfix release.
tls_cert_reqs not being set to SSL_VERIFY_PEER by default. This
meant that clients were not verifying the server certificate when connecting
over TLS. This affects the C, C++ and Python libraries.Source and binaries are available on the download page.
This is a bugfix release.
Binaries should be available shortly.
On a previous post I described how to make mosquitto debian packages. This turned out to be a bit problematic, so I've now put up an experimental debian repository for mosquitto. It includes packages for the i386, amd64, armel and raspberry pi (raspbian armhf ) architectures.
It's worth repeating that this is experimental - there are package changes that haven't been vetted by a Debian developer so it's possible something will break. I've tested myself and had no problems so far.
To use the new repository you should first import the repository package signing key:
wget http://repo.mosquitto.org/debian/mosquitto-repo.gpg.key sudo apt-key add mosquitto-repo.gpg.key
Then make the repository available to apt:
cd /etc/apt/sources.list.d/
Then one of the following, depending on which version of debian you are using:
sudo wget http://repo.mosquitto.org/debian/mosquitto-jessie.list sudo wget http://repo.mosquitto.org/debian/mosquitto-stretch.list sudo wget http://repo.mosquitto.org/debian/mosquitto-buster.list
Then update apt information:
apt-get update
And discover what mosquitto packages are available:
apt-cache search mosquitto
Or just install:
apt-get install mosquitto
I just discovered that Shane Hanna has written a Go language binding for libmosquitto available at https://bitbucket.org/shanehanna/mosquitto/. Good work Shane! Note that the readme file states:
Doesn't expose all of libmosquitto, just what I've needed so far.
so you shouldn't necessarily expect everything to work.
This is a feature and bugfix release.
max_inflight_messages and max_queued_messages not being applied.clean_session correctly.clean_session==false now remove unused subscriptions on
broker restart.mosquitto_lib_cleanup() where possible.mosquitto_loop_read() and mosquitto_loop_write() now handle errors
themselves rather than having mosquitto_loop() handle their errors. This
makes using them in a separate event loop more straightforward.mosquitto_loop_forever() / loop_forever() function call to make
simple clients easier.mosquitto_tls_set() will now return an error or raise an exception
immediately if the CA certificate or client certificate/key cannot be
accessed.mosquitto_loop() if a system call is
interrupted. This prevents disconnects/reconnects in threaded mode and
simplifies non-threaded client handling.mosquitto_message_retry_set().mosquitto_topic_matches_sub() for subscriptions with + as the final
character. Fixes bug #1085797.max_packets parameter which is now unused.error_string() function. Fixes bug #1086777.mosquitto_pub -l -q 2 disconnecting before all messages were
transmitted.As Debian has been in feature freeze since before Mosquitto 1.0 was released, it will be a long time until there is an updated version of Mosquitto in Debian. It is, however, fairly straightforward to do the packaging yourself. Here's how to do that from the command line.
Download and unpack the mosquitto source tarball:
wget http://mosquitto.org/files/source/mosquitto-1.1.2.tar.gz tar -zxf mosquitto-1.1.2.tar.gz
Rename the tarball to match Debian requirements:
mv mosquitto-1.1.2.tar.gz mosquitto_1.1.2.orig.tar.gz
The current mosquitto packaging files are available at https://packages.debian.org/source/stable/mosquitto - you want the .debian.tar.xz.
The next step is to build the package, but you may find that you need to install some packages first:
sudo apt-get install build-essential python quilt libwrap0-dev libssl-dev devscripts python-setuptools
To build the packages do
cd mosquitto-1.1.2/ debuild
You should now have a list of .deb files in the parent directory which you can install with:
sudo dpkg -i <deb file>
Please leave comments if you find this useful or have any problems.
This is a bugfix release.
use_identity_as_username set to true but a
client connects without a certificate.WITH_TLS=yes.This is a bugfix release.
mosquitto_sub -l incorrectly only sending one message per second.
