Commit c7338167 authored by Geoff Simmons's avatar Geoff Simmons

Add a file implementation for the MQ interface, and use it for the

general 'make check' tests, to test without a message broker running.
Also add --enable/--disable options to configure to optionally build
the MQ implementations.

-------------------------------------------------------------------
File implementation of the MQ interface for the Tracking Log Reader
-------------------------------------------------------------------
:Author: Geoffrey Simmons
:Date: 2015-04-27
:Version: 1.0.0
:Manual section: 3
DESCRIPTION
===========
``libtrackrdr-file.so`` provides an implementation of the tracking
reader's MQ interface to write messages to a file, as an aid to
testing and debugging. See ``include/mq.h`` in the ``trackrdrd``
source distribution for documentation of the interface.
To use this implementation with ``trackrdrd``, specify the shared
object as the value of ``mq.module`` in the tracking reader's
configuration (see trackrdrd(3)). The configuration value may be the
absolute path of the shared object; or its name, provided that it can
be found by the dynamic linker (see ld.so(8)).
``libtrackrdr-file`` also requires a configuration file, whose path is
specified as ``mq.config_fname`` in the configuration of
``trackrdrd``.
BUILD/INSTALL
=============
The sources for ``libtrackrdr-file`` are provided in the source
repository for ``trackrdrd``, in the subdirectory ``src/mq/file/``.
``libtrackrdr-file`` is built as part of the global build for
``trackrdrd``; for details and requirements of the build, see
trackrdrd(3).
To specifically build the MQ implementation (without building all of
the rest of ``trackrdrd``), it suffices to invoke ``make`` commands in
the subdirectory ``src/mq/file`` (after having executed the
``configure`` script for ``trackrdrd``)::
# in the trackrdrd repo
$ cd src/mq/file
$ make
The global ``make`` command for ``trackrdrd`` also executes both of
these for the file plugin.
To install the shared object ``libtrackrdr-file.so``, run ``make
install`` as root, for example with ``sudo``::
$ sudo make install
In standard configuration, the ``.so`` file will be installed by
``libtool(1)``, and its location may be affected by the ``--libdir``
option to ``configure``.
CONFIGURATION
=============
As mentioned above, a configuration file for ``libtrackrdr-file``
MUST be specified in the configuration parameter ``mq.config_fname``
for ``trackrdrd``, and initialization of the MQ implementation fails
if this file cannot be found or read by the process owner of
``trackrdrd`` (or if its syntax is false, or if required parameters
are missing).
The syntax of the configuration file is the same as that of
``trackrdrd``.
These parameters can be specified:
=================================== ============================================
Parameter Description
=================================== ============================================
``output.file`` The file to which messages are written.
If exactly equal to ``-``, then messages
are written to stdout.
----------------------------------- --------------------------------------------
``append`` If true, then the output file is appended
to, otherwise it is overwritten. True by
default. This parameter has no effect if
output is written to stdout.
=================================== ============================================
The parameter ``output.file`` MUST be set.
