Release v3.9.1.0

[3.9.1.0] - 2021-03-17 "Luck-O-The-Radio"

API is compatible with C++ code written against previous v3.9 releases.

ABI (link time) compatibility is not guaranteed. Out-of-tree C++ code
linked to previous v3.9 releases should be rebuilt against this version.

Project Scope

  • (internal) Build system improvements and fixes
  • (internal) Use C++14 features instead of Boost where possible
  • Fewer compiler warnings (due to fixed code, not removal of warnings!)

OOT Support

  • cmake: standard FindGSL used in lieu of custom one, so OOTs should no longer
    copy this module from the GNU Radio tree if needed
  • modtool: better exception/error handling
  • modtool: will non-interactively add blocks with no parameters
    (--argument-list="")
  • PyBind11 header hash hotfixer
    (gr-utils/bindtool/scripts/binding-hash-hotfixer.zsh) makes life easier

GRC

  • Block param values can be shown as expressions and/or evaluated values. Under
    the View menu, see "Show parameter ..." options.
  • Better handling of gui hints, avoid hiding widgets in cases where some have
    GUI hints and some do not
  • Ensure that strings are valid utf8 when evaluating parameters
  • Save embedded python blocks/modules to hier_block_directory
  • Save config and update recent file sub-menu before executing flowgraph
  • Revert to previous "block id" display behavior
  • Fix drag n' drop issue with Quartz (macOS) backend
  • C++ generated code: remove gnuradio prefix from linked libraries
  • Python generated code: prefix generated modules with flowgraph id
  • connect() will be called for hier blocks even if they don't have ports
  • Check for PyYAML 3.11 (was checking for 3.10 even though 3.11 was required)

gnuradio-runtime

  • Default buffer size can be adjusted by setting buffer_size in the
    [Default] section of the GNU Radio config file. Otherwise, the longstanding
    default of 32768 is used.
  • Windows/Python: add DLL search path, as required by newer versions of Python

gr-audio

  • Windows: reduce priority of Windows native audio to LOW, preferring Portaudio

gr-blocks

  • Message Debug: prints warning when a non-PDU message is received on the
    Print PDU port
  • File Source handles EOF properly in non-seekable files (e.g., pipes)
  • Several bounds checking and boundary condition improvements
  • Remove DC Spike AutoSync algorithm fixed

gr-digital

  • MSK timing error detector improvement
  • Python bindings include control_loop parent class in child class
  • Correlation Estimator parameter threshold well documented

gr-fft

  • New window types: Nuttall, Blackman Nuttall, Nuttall CFD, Welch, Parzen,
    Exponential, Riemann, Gaussian and Tukey

gr-filter

  • Taps blocks (e.g., Low Pass Filter Taps) now propagate parameter changes
  • Filter Designer: IIR/Band Pass/Bessel works

gr-qtgui

  • Add toggling label and icon on plot play/stop button
  • Time Raster Sink: axis labels and ranges are configurable
  • Qt Chooser: label improvements

gr-uhd

  • DEPRECATION: UHD blocks currently accept control messages (e.g. for
    frequency change) as PMT pairs and tuples, in addition to the intended
    PMT dict format. In v3.11, only the dict format will be accepted.
  • Command note: freq messages in this version must be dicts. Additionally,
    the direction key must be present and set to TX or RX.
    Python example: pmt.to_pmt({'freq':100e6,'direction':'RX'})
    The original behavior may be restored in an update, but code should be
    converted to use the dict format in preparation for future versions.
  • set_filter() adds chan parameter
  • Python generated code improved for FE corrections
  • Allow control of frequency and gain in both directions at the same moment
  • Add command handler for mtune ("manual tune")
  • Add GPIO control via messages
  • Add start time param to GRC blocks
  • Support streaming modes: STREAM_MODE_START_CONTINUOUS,
    STREAM_MODE_STOP_CONTINUOUS, STREAM_MODE_NUM_SAMPS_AND_DONE,
    STREAM_MODE_NUM_SAMPS_AND_MORE
  • Documentation improvements
  • Tag sink demo example
  • Better logging of over/underflows, time errors and time tags
  • Added Python binding for ALL_LOS (all local oscillators)
  • uhd_fft application X11/Qt related cleanups

QA

  • waitFor(condition, ...) available for tests that use timeouts

Release 3.9.0.0

[3.9.0.0] - 2020-01-17

The future is not set, there is no fate but what we make for ourselves. In this
very spirit, GNU Radio 3.9 packs a whole bunch of power when it comes to
transforming the way GNU Radio and its ecosytem can be developed in the future.

Not only did we have great progressions from old dependencies that proved to be
all too problematic (SWIG, Python2), but also did we see an incredibly influx of
people actively working on how maintainable this code base is. This will nurture
the project for years to come.

All in all, the main breaking change for pure GRC users will consist in a few
changed blocks – an incredible feat, considering the amount of shift under the
hood. Mentioning large shifts, the work that went into the PyBind binding, the
CMake modernization, the C++ cleanup, the bug-fixing and the CI infrastructure
is worthy of explicit call out; I especially thank

  • Josh Morman
  • Thomas Habets
  • Jacob Gilbert
  • Andrej Rode
  • Ryan Volz

here.

For developers of OOTs, I'm sure PyBind11 will pose a surprise. If you're used
to SWIG, yes, that's more code to write yourself. But in effect, it's less code
that breaks, and when it breaks, it breaks in much more understandable ways.
Josh has put a lot of effort into automating as much of that as possible.
There's certainly no shortage of demand for that! The ecosystem (remember GNU
Radio's tagline?) is in a steady upwind. We've seen more, and more stable,
contributions from OOT maintainers. That's great!

For in-tree development, newer dependencies and removal of anachronisms will
make sure things move much smoother. Our CI is getting – lately literally every
day – better, which means we not only catch bugs earlier, but also allow for
much quicker review cycles.

One central change:

If you're contributing code upstream, we no longer need you to submit a CLA;
instead, we ask you to just certify, yourself, that you're allowed to contribute
that code (and not, e.g. misappropriating someone else's code).

That's what the DCO (Developer Certificate of Origin) is: Just a quick, "hey,
this code is actually for me to contribute under the project's license"; nothing
more.

Which means that our infrastructure will refuse to let your code into the tree
if you didn't add a

Signed-off-by: Maxime Example <maxime@example.com>

to your commit message. Luckily, git can do that for you: git commit -s.

Changed

Project Scope

  • We now require commits to be signed off (DCO); this means you have to
    attach -s to your git commit command line
  • License headers now SPDX format
  • C++14
  • use C++11 facilities in a lot of places where Boost was still used,
    especially smart pointers, range loops
  • lambdas where boost::bind was used
  • C11
  • Dependency versions:
    • Python 3.6.5
    • numpy 1.13.3
    • VOLK 2.4.1
    • CMake 3.10.2
    • Boost 1.65
    • Mako 1.0.7
    • PyBind11 2.4.3
  • Compiler options:
    • GCC 8.3.0
    • Clang 11.0.0 / Apple Clang 1100
    • MSVC 1910 (Microsoft VS 2017 15.0)
  • VOLK now "regular" dependency, not in-tree submodule
  • numpy now also a CMake-checked hard dependency for Python support
  • Exception Handling: throw by value, catch by reference (clang-tidy check)
  • C++11: Emplace in vectors where you can; brings performance boni, but not
    included in clang-tidy-checks
  • Further clang-tidy based code optimizations:
  • empty() instead of size() == 0
  • override where overriding virtual functions (which we do a lot)
  • Logging: removed all std::cerr and fprintf(stderr,…) by GNU Radio logging
  • Logging: Changed logging format for many multiline error logs
  • purged snprintf, printf logging
  • There were a lot of places where a malloc'ed object was used internally, where
    that was inappropriate. Using simple instance-holding fields now.
  • const for members that were only set at construction time is now desired,
    and implemented in most places
  • const -> constexp in a lot of places.
  • assert -> static_assert
  • An exception-throwing block will now terminate the flow graph process,
    configurable through top_block
  • gr-utils cleanup, folder restructuring
  • config version checks installed CMake file will accept "at least this version"
    now
  • PyBind11 replaces SWIG
    • Full tree conversion from SWIG to Pybind11 bindings
  • Doxygen now uses MathJax, full LaTeX installation no longer required

Release 3.8.0.0

Witness me!

Tonight, we release GNU Radio 3.8.0.0.

It's the first minor release version since more than six years, not without
pride this community stands to face the brightest future SDR on general purpose
hardware ever had.

Since we've not been documenting changes in the shape of a Changelog for the
whole of the development that happened since GNU Radio 3.7.0, I'm afraid that
these release notes will be more of a GLTL;DR (git log too long; didn't read)
than a detailed account of what has changed.

What has _not** changed is the fact that GNU Radio is centered around a very
simple truth:

Let the developers hack on DSP. Software interfaces are for humans, not the
other way around.

And so, compared to the later 3.7 releases, nothing has fundamentally modified
the way one develops signal processing systems with GNU Radio: You write blocks,
and you combine blocks to be part of a larger signal processing flow graph.

With that as a success story, we of course have faced quite a bit of change in
the systems we use to develop and in the people that develop GNU Radio. This has
lead to several changes that weren't compatible with 3.7.

This is an excerpt only:

Fixed

Project Scope

  • Roughly 36 dBBug, (ETOOMANYBUGS)
  • Fixed .so versioning

Changed

Project Scope

  • C++11
  • merged the wholeness of the next branch
  • Dependency version bumps: CMake, GCC, MSVC, Swig, Boost
  • New dependencies: MPIR/GMP, Qt5, gsm, codec2
  • Removed dependencies: libusb, Qt4, CppUnit
  • Python: Python 2 & Python 3 compatible. 3.8 will be the last Py2k-compatible
    release series
  • gengen was replaced by templates (if you don't know gengen, don't do any
    research; save yourself that sorrow)
  • Modern CMake (as far as feasible at this point)
  • VOLK version updated to v2.0.0
  • .clang-format file now dictates coding style
  • clang-format'ed the whole tree.
  • installed CMake files now tell about configuration

gnuradio-runtime

  • reworked fractional tag time handling, especially in the context of resamplers

GRC

  • C++ generation as option
  • YAML instead of XML
  • removed blks2
  • much better canvas tooling
  • consistent gobject usage
  • ROUNDED ARROWS

gr-qtgui

  • moving from Qt4 to Qt5

gr-utils

  • gr_modtool now vastly improved

gr-vocoder

  • improved versatility
  • removed in-tree libgsm, libcodec2, use system-wide libs

Removed

Project Scope

  • Modules gr-comedi, gr-fcd and gr-wxgui are gone

gr-comedi

  • nobody could remember who used this, or for what. It has seen 0 active code
    contributions in the 3.7 lifecycle

gr-digital

  • python-based packet_encoder and related tools: Bugs that were sporadic and
    never fixed, so after long deprecation, we're removing it

gr-fcd

  • since it's currently untestable by the CI, it's being removed, as there was no
    code contributions. Generally, we strive to include all batteries with GNU
    Radio. Re-integration within a more general SDR interface would be desirable.

gr-utils

  • removed PyQwt (dead) based tools

gr-wxgui

  • Unmaintained, breaks on increasingly many systems, always was slower than
    Qtgui. We've been starting to tell people to migrate to Qt since at
    least 2015. Now, we're finally removing it.
