2006-08-01  Achilleas Anastasopoulos <anastas@umich.edu>

        * src/lib/general/gr_packed_to_unpacked_XX.cc.t,
        src/lib/general/gr_unpacked_to_packed_XX.cc.t: fixed bug in
        multiple stream support.

2006-07-06  Tom Rondeau  <trondeau@vt.edu>

        * src/python/gnuradio/blksimpl/gmsk2.py:
        Added AGC to GMSK code.
        
2006-07-06  Tom Rondeau  <trondeau@vt.edu>

        * src/python/gnuradio/blksimpl/Makefile.am: 
        Call to gmsk.py was causing error after removal of gmsk.py file.
        Removed call in Makefile.am to this.

2006-07-05  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/blksimpl/gmsk.py: Removed long deprecated
        code.  We'll give this a week or so for the dust to settle, then
        we'll rename gmsk2.py to gmsk.py

2006-06-29  Tom Rondeau  <trondeau@vt.edu>

        * src/lib/general/gr_correlate_access_code_bb.cc (work): 
        Removed branches; cleaned up code to only deal with a 180 degree phase shift in
        BPSK.

2006-06-28  Tom Rondeau   <trondeau@vt.edu>

        * src/python/gnuradio/gr/qa_correlate_access_code.py (test_correlate_access_code.test_001):
        Changes to access code correlator to handle BPSK phase reversal 
        killed qa_correlate_access_code. Modified the access code search in
        test_001 to all the test to pass properly.

2006-06-28  Tom Rondeau  <trondeau@vt.edu>

        * src/lib/general/gr_constellation_decoder_cb.cc: 
        Set Compute_EVN=false by default (to clean up the output)

2006-06-20  Tom Rondeau  <trondeau@vt.edu>

        * src/lib/general/gr_costas_loop_cc.{h,cc,i}: modified to support
        both BPSK and QPSK via "order" constructor argument.  Removed
        unused ref_phase ctor arg.
        
2006-06-20  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_probe_avg_mag_sqrd_{f,c}.{h,cc,i}: added accessor
        for threshold.

        * src/python/gnuradio/blksimpl/pkt.py: result of refactoring
        gmsk2_pkt.py.  This is the common packet handling framework, and
        is modulation independent.  gmsk2_pkt is now deprecated.

        * src/python/gnuradio/blksimpl/gmsk2_pkt.py: added deprecation warning.
        
        * src/python/gnuradio/packet_utils.py (make_packet): added
        bits_per_baud parameter to handle QPSK, etc in the future.

2006-06-08  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_feval.{h,cc,i},
        src/python/gnuradio/gr/qa_feval.py: new C++/python helper that
        allows C++ code to evaluate a function defined in Python.  Uses
        SWIG directors.

2006-06-06  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_unpack_k_bits_bb.cc (work): bug fix.  Was
        computing the wrong answer and writing *way* too much data if k was > 1.
        * src/python/gnuradio/gr/qa_unpack_k_bits.py: new ;)

        * src/lib/general/gr_diff_decoder_bb.{h,cc,i}: new.  differential

        src/lib/filter/short_dotprod_mmx64.S: changed all occurrences of
        .align 16 to .p2align 4 to avoid ambiguous interpretation of .align
        argument.

        
2006-05-29  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/blksimpl/gmsk2_pkt.py: now uses string of 1's
        and 0's for access_code representation.  Refactored to use
        correlate_access_code_bb and frame_sink_1 instead of packet_sink.

        * src/lib/general/gr_binary_slicer_fb.{h,cc,i}: new
        * src/lib/general/gr_qpsk_slicer_cb.{h,cc,i}: deleted.  Use
        gr_constellation_decoder_cb instead.

2006-05-29  Eric Blossom  <eb@comsec.com>
        
        * src/lib/general/gr_clock_recovery_mm_cc.cc: revised

        src/utils/read_char_binary.m, src/utils/read_complex_binary.m,
        src/utils/read_float_binary.m, src/utils/read_int_binary.m, 
        src/utils/read_short_binary.m: modified to be compatible with
        MATLAB.
        
2006-05-26  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_framer_sink_1.{h,cc,i}: new.  Refactored from
        gr_packet_sink.  Use in combination with gr_correlate_access_code_bb.

2006-05-24  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_diff_encoder_bb.{h,cc,i}: new. differential encoder.

        * src/lib/general/gr_constellation_decoder_cb.{h,cc,i}: new.
        Maps i/q value to closest constellation point and return value
        associated with the point. This probably obsoletes 
        gr_qpsk_slicer_cb.

        * src/lib/general/gr_qpsk_slicer_cb.{h,cc,i}: new.
        * src/lib/general/gr_unpack_k_bits_bb.{h,cc,i}: unpack bytes
        containing k valid bits, into bytes, 1 bit per byte.

        * src/lib/general/gr_correlate_access_code_bb.{h,cc,i}: new.
        General purpose block for searching for access codes (sync
        vectors).  Can handle any sync vector between 1 and 64 bits.

2006-05-23  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_diff_phasor_cc.{h,cc,i}: new.  Compute phase
        difference as a complex number between adjacent complex items in
        stream.  This is useful for demodulating differentially encoded PSK.

        * src/python/gnuradio/gruimpl/mathmisc.py (log2): new function.

        * src/lib/general/gr_firdes.cc (root_raised_cosine): force ntaps
        to be odd.

2006-05-21  Martin Dudok van Heel <nldudok1 at olifantasia.com>

        Added generic test class gr_test.
        gr_test is a gnuradio block meant to be used in a flow_graph.
        It doesn't do much processing, but you can specify from python every parameter you need to for testing.
        For example history, output_multiple, input and output signature, decimation and such.
        Especially handy for testing setting up the buffers.
        It also touches every available input and output to check for segfaults.
        You can also instruct it to not consume all ninput_items or not produce all noutput_items.
        
        There is also a new script test_buffers.py in src/tests which uses gr_test to test setting up the buffers.
        It is NOT automatically run by make check yet, because it will fail with an assert when it reaches circbuf memory limit of the system.
        (On linux: Trying to setup a buffer >shmmax
        Note that you can set the smmax limit manually on a linux 2.6 system in the following way in a root console)
        #set shmmax limit manually to 300MB
        echo 300000000 >/proc/sys/kernel/shmmax

        * src/lib/general/Makefile.am: added gr_test
        * src/lib/general/general.i: added gr_test
        * src/lib/general/gr_test.cc: new
        * src/lib/general/gr_test.h: new
        * src/lib/general/gr_test.i: new
        * src/lib/general/gr_test_types.h: new
        * src/tests/test_buffers.py: new script to test setting up the buffers using gr_test

2006-05-21  Martin Dudok van Heel <nldudok1 at olifantasia.com>

        Solved the following bugs which result from incorrect buffersize setup:
        sched: <gr_block gr_test (21)> is requesting more input data
          than we can provide.
          ninput_items_required = 8192
          max_possible_items_available = 8191
          If this is a filter, consider reducing the number of taps.

        python: src/lib/runtime/gr_buffer.h:108: unsigned int gr_buffer::index_sub(unsigned int, unsigned int):
         Assertion `(unsigned) s < d_bufsize' failed.
        Aborted

        * src/python/gnuradio/gr/flow_graph.py: resolved above bugs by adding + mdown.history() to nitems when appropriate

2006-04-24  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_chunks_to_symbols_XX.{h,cc,i}.t,
        src/lib/general/gr_packed_to_unpacked_XX.{h,cc,i}.t,
        src/lib/general/gr_unpacked_to_packed_XX.{h,cc,i}.t: 
        new pseudo-templates for generating family of blocks.  Patch
        submitted by Achilleas Anastasopoulos <anastas@umich.edu>, touched
        up by Eric.

2006-04-24  Martin Dudok van Heel <nldudok1 at olifantasia.com>

        * src/python/gnuradio/gr/flow_graph.py (buffer_sizes.allocate):
        increase buffer size allocation for blocks with a large
        output_multiple, not just those that are decimators.

2006-04-05  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_pll_carriertracking_cc.i: added
        squelch_enable and set_lock_threshold methods.

        * src/lib/general/gr_clock_recovery_mm_cc.h: removed erroneous
        class prefix to method.  GCC 4.1.0 complains ;)

2006-04-03  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_pll_carriertracking_cc.cc (phase_detector):
        fixed typo.

        * src/python/gnuradio/gr/prefs.py: don't load prefs if
        GR_DONT_LOAD_PREFS environment variable is set.  run_tests sets
        this to avoid interactions with system and user prefs during
        make check.

        * src/python/gnuradio/gr/qa_rational_resampler.py: disabled two
        tests that were causing hangs on SuSE 10.0.  Should be investigated.

2006-03-30  Eric Blossom  <eb@comsec.com>

        * src/lib/filter/gr_fft_filter_ccc.{h,cc},
        src/lib/filter/gr_fft_filter_fff.{h,cc}: reworked to allow
        safer setting of new taps after instantiation.

2006-03-29  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_prefix.{h,cc,i}: new function that returns
        installation prefix directory (--prefix argument to configure).

        * src/lib/general/gr_prefs.{h,cc,i}: reworked implementation to
        use python ConfigParser.
        * src/python/gnuradio/gr/prefs.py: moved from
        src/python/gnuradio/prefs.py to solve initialization problem.

        * src/lib/general/gr_stream_to_vector.{h,cc,i}: renamed from gr_serial_to_parallel
        * src/lib/general/gr_vector_to_stream.{h,cc,i}: renamed from gr_parallel_to_serial
        * src/lib/python/gnuradio/gr/__init__.py: new aliases for
        backwards compatibility with rename.

        * src/lib/swig/Makefile.am: cleanup for make distcheck.

        * src/lib/general/gri_ringbuffer.{h,cc}: removed.  Use
        gr_buffer/gr_buffer_reader instead.

2006-03-27  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_prefs.{h,cc,i}: renamed parameter from "val" to
        "v" to work around issue in SWIG 1.3.{28,29} and/or g++ 4.0.2.

        * src/lib/general/gr_prefs.{h,cc,i}, src/python/gnuradio/prefs.py:
        new class for user preferences.  This uses SWIG directors (serious
        magic), to have the actual implementation be in python, but
        callable transparently from C++.  We'll use this for user prefs
        such as audio module, audio module options, etc.

2006-03-25  Eric Blossom  <eb@comsec.com>

        * src/lib/io/gri_logger.h (class gri_logger): new class that can
        safely log to a file from within a JACK or portaudio callback.
        Uses a ringbuffer to communicate with a separate thread that
        writes the file.

2006-03-17  Eric Blossom  <eb@comsec.com>

        * src/lib/runtime/gr_buffer.cc (gr_buffer_reader): added missing

        src/lib/omnithread/ot_posix.h, src/lib/omnithread/posix.cc,
        src/lib/omnithread/nt.cc: mods to

        These changes enabled discontinous transmission of usrp packets.
        The treatment of history was slightly changed.  Now we provide
        zeros for the initial delay lines and produce N outputs for N

        * src/python/gnuradio/gr/flow_graph.py (flow_graph._connect_inputs):
        account for initial history when attaching buffer reader.
        * src/lib/runtime/gr_buffer.{h,cc,i} (gr_buffer_add_reader): modified to
        provide zeros for initial history.

        * src/lib/general/gr_clock_recovery_mm_ff.cc: limit excursions of
        omega using omega_relative_limit.  Added conditional diagnostic logging.

2005-10-05  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/gr/hier_block.py (hier_block_base.__init__):
        reenabled weakref to break circular graph.
        * src/python/gnuradio/gr/basic_flow_graph.py (basic_flow_graph),
        src/python/gnuradio/gr/flow_graph.py (flow_graph):
        removed __slots__ class attribute so we can create weakrefs to
        flow graphs.

        * src/python/gnuradio/gr/gr_threading.py: New.  Load appropriate bug fix.
        * src/python/gnuradio/gr/gr_threading_23.py (Thread.join): bug fixed
        version of python 2.3 threading.py.

        backed out use of weakref.
        * src/python/gnuradio/gr/scheduler.py (scheduler.wait): backed out
        "Control-C fix".

2005-10-02  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/blksimpl/wfm_tx.py: New. Wide band FM tx block.

2005-09-29  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/gr/hier_block.py (hier_block_base.__init__):
        store weakref to flow_graph to break circular graph so that flow
        graph can be reclaimed right away.

        * src/python/gnuradio/gr/flow_graph.py (flow_graph.__del__): call
        self.stop() to ensure that i/o devices get shutdown gracefully.

        * src/python/gnuradio/gr/scheduler.py (scheduler.wait): calling

2005-08-26  Eric Blossom  <eb@comsec.com>

        * src/python/gnuradio/gr/qa_rational_resampler.py
        (test_rational_resampler.test_002_interp):  reduced random test
        from 10k cases to 1000 cases.  The 10k case turns up a single
        failure.  FIXME figure out why!

        * src/python/gnuradio/gr/qa_fsk_stuff.py
        (test_bytes_to_syms.test_simple_framer):  fixed test case to
        reflect 0x55 trailing tail.

        * src/lib/filter/qa_gr_fir_ccc.cc (test_random_io): Ensure 16-byte
        input alignment to meet contract with SIMD ccc kernel.

2005-08-25  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_simple_correlator.cc: average the samples in
        the sync field and use this to set the slicing level for the
        payload.  This helps account for frequency offsets between the Tx
        and Rx sides.

2005-08-24  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_simple_framer_sync.h: include GRSF_TAIL_PAD
        in GRSF_OVERHEAD.

        * src/lib/runtime/gr_single_threaded_scheduler.cc (main_loop): now
        only invoke sources if we are not making progress.  This avoids
        blocking (in most cases) unless we've got nothing better to do.

        * src/lib/filter/gr_freq_xlating_fir_filter_XXX.cc.t
        (build_composite_fir): reversed taps to fix problem introduced
        when we "rationalized" the tap ordering a while ago.  [We are
        missing a unit test for this...]

2005-08-22  Matt Ettus  <matt@ettus.com>

        * src/python/gnuradio/blksimpl/gmsk.py:
                made several changes to the filters on both TX and RX.
                The demod filter (integrate_taps) should not average
                over multiple samples.  In reality, a few samples should 
                work, so I'm not sure why it doesn't here.

2005-08-22  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_simple_correlator.cc (general_work): removed
        incorrect magic number and replaced with constant expression.
        [Almost as embarrassing as a buffer overflow]

2005-08-21  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_simple_framer_sync.h: added one byte tail
        padding to ensure that correlator has a chance to get synced in
        case it was later on the previous packet.

        * src/lib/general/gr_simple_correlator.cc (general_work):
        corrected to use count_bits64.

2005-08-19  Eric Blossom  <eb@comsec.com>

        * doc/Makefile.am: clean-local now uses $(RM) -fr

2005-08-18  Eric Blossom  <eb@comsec.com>

        * src/lib/general/gr_count_bits.{h,cc}: new gr_count_bits64.
        
        * src/lib/general/gr_simple_correlator.{h,cc},
        src/lib/general/gr_simple_framer.{h,cc},
        src/lib/general/gr_simple_framer_sync.h,
        src/python/gnuradio/gr/qa_fsk_stuff.py: changed length of SYNC
        code from 32 to 64 bits.

2005-08-16  Andrew Thomas Beck <Andrew.Beck@postgrads.unisa.edu.au>

        * src/lib/runtime/gr_vmcircbuf_createfilemapping.cc (gr_vmcircbuf_createfilemapping): fixes.

        src/lib/runtime/gr_block_detail.i, src/lib/runtime/gr_buffer.i:
        fixes for SWIG 1.3.25.  Thanks to Job de Haas for a big clue!

2005-08-08  Martin Dudok van Heel <nldudok1 at olifantasia.com>

       Addded a new block to convert from float to unsigned char. Needed for new tv-reception example.

       * src/lib/general/gri_float_to_uchar.{cc,h}: new
       * src/lib/general/Makefile.am: changed. Added gr_float_to_uchar and gri_float_to_uchar. (Also added gr_float_to_char.h which was
         forgotten in previous patch to add gr_float_to_char)   
       * src/lib/general/general.i: changed. Added gr_float_to_uchar and gri_float_to_uchar.

2005-07-28  Eric Blossom  <eb@comsec.com>
