- A majority of the changes for this release related to
* GRC-Qt fixes and parity with the Gtk version
* UHD/RFNoC updates
* CI, modtool, and other devel/infrastructure updates
- New subpackages gnuradio-[bash|fish|zsh]-completion
OBS-URL: https://build.opensuse.org/package/show/hardware:sdr/gnuradio?expand=0&rev=155
- Update to version 3.10.11.0
- Changed
* Project
+ Const (keyword) cleanup in a large number of files. QtGUI
code uses const in many more places.
* Runtime
+ Add persistent() function to gr paths module. This function
returns either the value of the XDG_CACHE_HOME environment
variable, or appdata()/.local/state.
* GRC
+ Work continues on the Qt version of GRC (gnuradio-companion --qt).
While the Gtk version is still the default, we're getting
close to the point where the Qt version can be the default.
+ Generated Python code now includes a startup event
(flowgraph_started) to the top level class. This was added
specifically to avoid a race in the Variable Function Probe
block, and may be useful elsewhere.
+ Struct variables have not been usable since around v3.8. Fixed!
+ Paths are now based on gr paths, where they were previous
hardcoded to the user's home directory.
+ C++ hier block code paths fixed (so hier blocks work again).
+ Block connection line shape and width are now preferences.
* gr-blocks
+ New Burst To Stream block transforms a bursty tagged stream
into a continuous stream by inserting zeros in the output
between input packets whenever no packets are available at
the input.
* gr-digital
+ FLL Band Edge power calculations fixed, along with thread
safety issues.
* gr-fec
+ Unused RS code removed - unlikely anyone will notice.
* gr-filter
+ Numpy float_ changed to float64 for Numpy 2.0 compatibility.
* gr-fft
+ Vector version of FFT fft_v library function (calls fftw)
thread safety improved.
* gr-uhd
+ Do not require PyQt5 for non-graphical configurations.
* modtool
+ Many bug fixes and cleanups, resulting in more reliable
operation. That sounds really good, right?
+ Remove dependency on the "click plugins" package.
+ Appending new blocks to CMake files respects closing parens.
* Build system and packaging
+ CMake minimum versions were out of sync in different places,
fixed.
+ Incorrect Qwt maximum version removed.
- Last two patches gnuradio-fix-error-message-for-Qwt-version.patch
and gnuradio-remove-maximum-version-for-Qwt.patch removed as
appliedn upstream.
- Containd fix for latest spdlog (Tumbleweed).

- Update to version 3.10.9.1
- Changed
* Project
+ Python minimum version is now 3.7.2, vs 3.6.5, to support type
hints.
+ Add tox.ini, so that editors use the same formatting as
github CI.
+ Use pointers to pass s32fc arguments to VOLK in gr-blocks,
gr-digital, and gr-dtv to avoid undefined behavior. The fix
is conditional on VOLK 3.1.0, which add a new supporting
function.
* Runtime
+ Disallow None for pmt_t arguments in Python.
+ Support spdlog installations with internal or external libfmt.
* GRC
+ Use text labels to specify types for block parameters,
instead of background colors which were difficult to
read/remember.
+ Enable setting of documentation URLs, relative or absolute in
yaml. This allows OOTs to use the documentation link in the
block parameter dialog.
+ Disallow use of block ids that are Python keywords and
"gnuradio".
+ Add type annotations in some places (required bump to
Python 3.7.2).
+ Use C version of YAML loader (yaml.CSafeLoader) for
better performance.
+ Connections may have properties for supported connection
domains. This feature was added for RFNoC connections. Standard
stream and message connections do not support this feature,
but they may in future versions.
+ Check grc file version. The above feature required a
version bump to "2". Where no connection properties are
used, version "1" is still emitted. Note that previous
versions of GRC do not check for file version. RFNoC
flowgraphs with connection properties will fail to load
in previous versions as a result.
+ Fix bug where an impressive number of backslashes were
added to some filenames.
* gr-dtv
+ Read expected data as little-endian
* gr-fec
+ Add FEC_API to CCSDS Reed-Solomon functions so they can be
used by OOTs.
* gr-qtgui
+ QT GUI Msg Push Button: add a callback for Message Value to
allow it to change at runtime.
* gr-uhd
+ RFNoC Rx-Streamer: Add start stream options
+ Add back-edge property to RFNoC connections
* Build system and packaging
+ Use utf-8 encoding when writing files in gr_python_install.

- Update to version 3.10.8.0
* Runtime
+ Add MAP_FIXED to circular buffer implementations using
shm_open() and mmap backed by tmp files.
+ PMTs can be formatted for logging (format wrapper added).
+ New io_signature::make() variant replaces makev(), and
optionally specifies buffer types.
+ Fix logging params to be compatible with C++20
* GRC
+ Add "Choose Editor" button to Python block properties. Use
the GTK app chooser.
+ Save choice to the config file.
+ Correct Python Qt imports in Hier blocks and flowgraph
templates.
* gr-blocks
+ Enable building the benchmark testing executable, which runs
tests on various math functions.
+ Repeat block implemented as a basic block (vs sync
interpolator) and output buffer allocation fixed.
+ Add a GRC example for Throttle usage.
* gr-digital
+ Add set_sps() to Symbol Sync.
+ Header Format: Fix CRC and OFDM formats, add option to
header_buffer to read bits lsb first, and refactor
extract_bits functions as templates.
+ Constellation Sink uses different colors for each input by
default.
+ Rework Constellation Soft Decoder, Constellation Object and
LDPC Decoder Definition.
+ Previously, the LDPC Decoder did not work at all. The sigma
parameter was removed from the decoder and an optional noise
power npwr parameter was added to the constellation.
* gr-network
+ Better support for vectorized output from UDP source. The
payload size must still be a multiple of item size * vector
size for this to work.
* gr-qtgui
+ Range widget eng_slider and eng modes can now be selected
in GRC.
+ Range widget and a couple of UHD apps now accept values on
editingFinished, rather than on returnPressed. Since UIs
generated by GRC do not have OK/Apply for such values,
there is no "correct" behavior. The behavior is now
selectable on the Entry widget.
+ Frequency Sink startup time improved where sample rate is low
* gr-soapy
+ RTLSDR buffer size may be specified
* gr-uhd
+ RFNoC NullSrcSink block added. The block may be both source
and sink.
+ Add support and examples for RFNoC loopback.
+ RFNoC Rx Radio adds issue_stream_cmd() and block message
handler.
* gr-zeromq
+ Explicitly shutdown and close source/sinks to prevent hangs
in some cases.
+ Require zmq.hpp (cppzmq) version with context_t.shutdown()
defined.
+ If shutdown is not defined, the gr-zeromq is disabled.
* Modtool
+ Add cmake-format support for generated modules
* Build system and packaging
+ Update Read-the-docs config to include build.tools

- Update to version 3.10.7.0
* Runtime
+ Setting the minimum buffer size should have the desired
effect now, and not be overwritten. NOTE: the value returned
by min_buffer_size() is not intended to indicate the actual
buffer size. Header Payload Demod was the only block
attempting to use this value, and was corrected.
+ Use a set to store thread group (more efficient)
+ Message Debug can now output via the logging system
+ The field prefs.singleton is no longer externally exposed
(was unintentional)
+ PMT dict can be generated more easily using pmt::dict_from_mapping()
* GRC
+ Save changes under all exit conditions (a couple were
previously missed)
+ Prevent silent Generate/Run failures for unsaved flowgraphs
* gr-analog
+ C++ code generation for Quadrature Demod
+ Add max_gain parameter for AGC
* gr-blocks
+ Probe Rate adds a name parameter, for clearer logging
+ Selector has a new "sync" more that consumes the same number
of items from all inputs. Default is now to consume as many
items as possible from the active input, and no more than
that many items from other inputs. The previous behavior was,
well, broken.
+ Throttle reset item count on restart, to avoid long delays
* gr-digital
+ Constellation Encoder and Decoder: constellation can be
changed at runtime
* gr-filter
+ Filter design tool: multiple improvements in bounds checking
and exception handling
+ Filter design tool: update QMessageBox to work in Qt5
* gr-network
+ Multiple memory management errors fixed in UDP Source/Sink
and TCP Sink

+ Better AGC and gain behavior in RTL, AirspyHF and SDRPlay
blocks
+ Support bias controls in RTL and SDRPlay blocks
* gr-uhd
+ Remove possibility of infinite recursion for network
overruns
+ Support fmtlib v10
+ RFNoC: bindings and block yml for Vector IIR, Replay and
Log Power blocks
+ RFNoC: add S16 format to RX Streamer
* gr-vocoder
+ Support additional codec2 modes
* Modtool
+ Don't override user-defined CMAKE_INSTALL_PREFIX

- Update to version 3.10.5.0
* Runtime
+ Python block have access to the block logger, as in C++
+ Default log level changed to INFO (from OFF)
+ Memory-based logger gr.dictionary_logger_backend() added for
log debugging
+ API Note: The Python block gateway is now completely
implemented in the PyBind11 wrapper, in order to clean up
Python dependencies. This is technically an API change, but
should not have any external effect.

all platforms
+ Python IO signature replication (multiple ports specified by
one signature) fixed
* GRC
+ Continue processing block connections after a connection
error occurs
+ Drawing/scaling fixes that improve user experience on HiDPI
and Windows machines

point comparison
* gr-blocks
+ Probe Signal cross platform reliability improved by better
thread synchronization
* gr-digital
+ CRC32 and CRC16 blocks use little-endian order regardless of
host order. This is a wire format change. The options were to
have different endian machines unable to communicate, or older
and newer versions unable to communicate. Note that there is
a more general set of blocks (CRC Append and CRC Check) that
are recommended for use wherever possible.
+ Packet headers use consistent bit order across machines
+ Floating point/rounding fix in constellation lookup table
* gr-fec
+ LDPC G matrix n and k can be access from Python
