	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
	implementation based on G. R. Danesfahani, T.G. Jeans,

	* 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.

	* 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.

	"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.

	src/lib/omnithread/ot_posix.h, src/lib/omnithread/posix.cc,
	src/lib/omnithread/nt.cc: mods to
	allow specifying a max count on semaphores. This allows the
	construction of binary semaphores by passing max_count=1 to the ctor.
	The default behavior is unchanged.

2006-03-13  Eric Blossom  <eb@comsec.com>

	* src/lib/general/gr_pll_carriertracking_cc.cc (work): refactored
	loop control.

2006-03-12  Stephane Fillod  <f8cfe@free.fr>

2005-08-28  Eric Blossom  <eb@comsec.com>

	* src/lib/general/malloc16.c: fixed 64-bit pointer to int cast problem.

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>

2005-07-18  Stephane Fillod  <f8cfe@free.fr>

	* config/gr_libgnuradio_core_extra_ldflags.m4,
