0.1.11
	
2019-08-26  sverker  <sverker@sverker-HP-Pavilion-g6-Notebook-PC>

	* Added information that this is for Python 2 only and a Python 3
	version is available.

	guppy 0.1.10
	
	
2013-04-25  sverker  <sverker@sverker-HP-Pavilion-g6-Notebook-PC>

	* guppy/sets/test.py (Test.test1): Added checks for Python 2.7

2011-05-24  Sverker Nilsson  <sverker@sverker-laptop>

	* src/heapy/hv_cli_dictof.c (hv_get_objects): New function that
	emulates gc_get_objects because of optimizations to the dict
	implementation which made them non-gc-tracked sometimes.
	
	(hv_cli_dictof_update_new_method): Relies on new function
	hv_get_objects to get at all dict objects in the heap.

2011-02-24  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/Part.py : Removed a failing assert in lack of a
	better solution. The result may perhaps differ sometimes from
	the true result, depending on the definition heap before/after.
	

2010-06-08  Sverker Nilsson  <sverker@sverker-laptop>

	* src/sets/bitset.c (mutbitset_iop_PyLongObject): Don't multiply
	with SHIFT if _PyLong_Frexp is used
	
	* guppy/heapy/test/test_Part.py (MixedCase.test_1): Changed the
	test result if sys.version >= 2.7; because the size of strings
	was optimized 8 bytes. (How ? )

	* src/sets/bitset.c (mutbitset_iop_PyLongObject): Used
	_PyLong_Frexp instead of _PyLong_AsScaledDouble if
	PY_VERSION_HEX >= 0x02070000 . (_PyLong_AsScaledDouble disappeared
	but I think I should complain, couldn't figure out how to add an
	issue with the tracker.)

2010-02-16  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/sets/test.py (Test.test16.tsv): Expected OverflowError
	instead of ValueError, an inconsequential change to do with
	possiboe test error reporting.

2010-02-15  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/test/test_Classifiers.py
	(SpecialCases.test_dictowner, SpecialCases.test_alt_retclaset):
	Changed to use clock() instead of time() for cpu time
	measurements. Added adaptive loop count as the time in some cases
	were down to 0.01 s - which may be the resolution of clock(). Now
	makes the time be about 0.5-1 s regardless of CPU speed.

	* guppy/heapy/test/test_Path.py (NewTestCase.test_1): 
	Changed to use clock() instead of time() for cpu time measurements
	in a test that is not currently used, just in case we begin to use it.
	
	
2010-02-14  Sverker Nilsson  <sverker@sverker-laptop>

	* src/sets/nodeset.c (nodeset_op_set): Just an inconsequential
	change, it had two returns after each other.

	* src/sets/bitset.c (mutbitset_iop_PyLongObject): 
	In the latest change where a loop over pos was added, changed type
	from int to NyBit.
	
	* src/sets/bitset.h: Checks endianness and defines macros to
	handle it.
	* src/sets/bitset.c (immbitset_long): 
	* src/sets/bitset.c (mutbitset_iop_PyLongObject): 
	Changes to work with big endian.
	
2010-01-02  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/etc/KnuthBendix.py
	(KnuthBendix.make_confluent.add_reduction): Added missing argument
	to % in error message

2009-08-30  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/Use.py (_GLUECLAMP_): Added loadall method

	Version 0.1.9
	
2009-06-23  Sverker Nilsson  <sverker@sverker-laptop>

	* specs/index.gsl: download mentions today's date

	* guppy/sets/test.py: Made it try numpy.random instead of
	RandomArray; revert to random if no numpy.random could be
	installed so more tests can get done albeit slower.

	* MANIFEST.in: added specs/*.py

	* ANNOUNCE : Added advertisement for http://sncs.se

2009-06-18  Sverker Nilsson  <sverker@sverker-laptop>

	* specs/index.gsl: Changed wording of tested pythons to exclude
	having tested with python2.3 in 32 bit mode.

	* src/sets/bitset.c (bits_first,bits_last): Changed to use #if
	directive to get rid of warnings in 32-bit mode.

	* src/sets/bitset.h (NyBits_N): Changed definition to use
	ULONG_MAX to be able to use it in preprocessor #if directive.

	* README (TEST): changed sample output to begin with test of sets.

	* setup.py (doit): long_description now starts with newline to
	look better in PKG-INFO

	* specs/heapy_tutorial.gsl: new file

	* guppy/heapy/test/test_dependencies.py : new file

2009-06-16  Sverker Nilsson  <sverker@sverker-laptop>

	* specs/index.gsl: Added interactive help to example which was
	moved to documentation section.

	* src/sets/bitset.c (mutbitset_pop): changed type of i from NyBit to
	int to work in 64 bits with test7 in sets/test.py .
	(bits_last): made it work with 64 bits by testing the upper 32-bit half
	(bits_first): made it use NyBits_N instead of NyBits_64 
	(bits_last):  made it use NyBits_N instead of NyBits_64 , NyBits_32
	(NyMutBitSet_pop): changed 1<<i to 1l<<i to work with 64 bits with
	test12 of test.py.

2009-06-12  Sverker Nilsson  <sverker@sverker-laptop>

	* ANNOUNCE: Tells about interactive help with example.

	* specs/index.gsl: Download section updated for 0.1.9. Credits

2009-01-09  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/gsl/Tester.py (TestOf.make_cat.get_example_expr): Made the
	example values be regenerated each time. (Unless 0 is true.)
	Affects speed sometimes (an extra function call per arg) but may
	also be faster.

	* guppy/heapy/Use.py (_GLUECLAMP_.load): changed usereadline to
	use_readline to correspond to doc .

	* guppy/heapy/Prof.py (Menu.delete): Removed commented-out lines
	to delete commands.

2008-11-03  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/UniSet.py (UniSet & IdentitySet): Removed several
	_get_xxx methods and put the definitions directly in properties as
	lambdas with docstrings (to clean up result of help()) . 

2008-10-31  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/Prof.py (_GLUECLAMP.pb_): Added docstring

	* guppy/heapy/Monitor.py (monitor): Added docstring

	* guppy/heapy/UniSet.py (UniSet etc): Made the docstrings of _get_ 
	wording in terms of attributes rather than methods.

2008-10-28  Sverker Nilsson  <sverker@sverker-laptop>

	* src/sets/bitset.c (mutbitset_iop_PyLongObject): Made explit long
	cast to long for num_poses, to get rid of warning from MSVC.

	* src/heapy/heapy.h: Removed DL_IMPORT macro usage.

	* src/sets/sets_internal.h: Removed all DL_IMPORT macros.
	  to get rid of warning from MSVC about inconsistent linkage.

2008-10-25  Sverker Nilsson  <sverker@sverker-laptop>

	* setup.py: Removed the extra compile args for MSWindows -
	  they were only there for debugging.

2008-10-24  Sverker Nilsson  <sverker@sverker-laptop>

	* Added debug parameter to hpy().test() and made all test_main
	  functions take that parameter. When true, it will be possible
	  to look into the failure stack with pdb.pm() .

	* Added Chad Austin's patch for MSWINDOWS
	  Made a temp os-determination. Have to check this out.
	  Changed macro FILL to return -1 to get rid of warning in a set init.
	  Made the initfunc in heapyc return an int to get rid of new warning.
	  Moved & renamed macro to NYFILL in new file src/include/guppy.h
	  which is intended to host general public guppy related includes.
	  Made corresponding changes FILL->NYFILL where used.
	
2008-06-18  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/doc/__init__.py (Tab): Added tabs for different help
	browsing environments. 

2008-06-17  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/doc/__init__.py (_GLUECLAMP_.help_instance): Added
	method. Also added Subject class.

	* guppy/heapy/UniSet.py (UniSet and subclasses): Added _help_url_
	attributes and _get_help which uses this via help_instance, but I
	began to think they should perhaps refer to the gsl kindnames
	instead. 

	* guppy/doc/__init__.py (Document): Added class Document, various
	restructurings in progress

2008-05-22  Sverker Nilsson  <sverker@sverker-laptop>

	* README (License): Added modify and redistribute wording to
	the License for clarity, still refers to MIT license.

	* Removed ihelp pkg. Changes to various files to reflect
	ihelp->doc .
	
	* Moved ihelp.__init__.py into guppy/doc
	
	* Moved top-level doc dir into guppy package
	
	*  ihelp.__init__.py : continued improving text html rendering

2008-05-21  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/Spec.py: 

	* guppy/gsl/Filer.py: 

	* guppy/gsl/DottedTree.py: 

	* guppy (docstring): Changed quotes to """ from ''' because I
	found pydoc.gui() (in Python 2.5) didn't recognize it otherwise.

	* guppy/etc/Glue.py (Share.getattr2): Made it try getattr3 with
	the CLAMP first even if it was a package.

2008-05-20  Sverker Nilsson  <sverker@sverker-laptop>

	*  (Default): Made ihelp directory and made guppy.help work first
	version. 

	* guppy/etc/PrettyPrintHTML.py: Added

	* guppy/gsl/Html.py (Node2Html): visit_comment: Made it not
	output anything to the XHTML file.

2008-05-14  Sverker Nilsson  <sverker@sverker-laptop>

	*  (specs/index.gsl): Added external resources documentation
	section and two external links.

2008-04-09  Sverker Nilsson  <sverker@sverker-laptop>

	*  (changelog): Renamed to ChangeLog since Emacs insists on having
	it as default name.

	* MANIFEST: added specs/genguppydoc.py

	* specs/index.gsl: Made it use css, improved table layout for doc
	and download.
	Added doc/css/guppy.css
	
	
	Version 0.1.8


2008-04-08  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/gsl/Main.py (find_aspects_inseq): as->as_
	  Several other GSL-related files as -> as_
	  untabified setup.py to look better in pypi
	

	Version 0.1.7

2008-04-07  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/test/test_View.py (FirstCasetest_cal_hiding): as->as_

	* guppy/heapy/test/test_UniSet.py (FirstCase): as->asrt

	* guppy/sets/test.py (test_set_operations and others): as->as_

	* guppy/heapy/test/test_Classifiers.py (SpecialCases.test_2): as->asrt

	* guppy/heapy/Classifiers.py (SoKind.__hash__): added

	* For Python 2.6a2 ^^^
	
	* specs/index.gsl: Added commentary in download section
	referringing to svn as source of latest changes esp. 64 bit.
	

	* Added specs/genguppydoc.py, to be able to regenerate docs from
	svn'd files.

2008-04-05  Sverker Nilsson  <sverker@sverker-laptop>

	* guppy/heapy/test/test_Classifiers.py (SpecialCases): 
	Relaxed the timing test in test_alt_retclaset with a factor 2
	from 2 to 4.
	
	* guppy/heapy/test/test_heapyc.py (TestHeapView):
	in test_timing:
	it failed in python2.3 64 bit, I removed the check for now,
	may check into this later...

	* src/sets/bitset.c (bits_first): Removed xxx etc from comment, no 
	problem with being hardcoded for size and now tested with 64 bits.
	(sf_realloc): changed the update of v->lo and v->hi to use better
	defined pointer-arithmetic within allocated arrays. This solved a
	problem with 64 bit mode in (at least) Python 2.4. May be a
	coincidence that it seemed to work with 2.5.

2008-03-17  Sverker Nilsson  <sverker@sverker-laptop>

	* Several files, to make it complie without warnings in 32 bit
	  mode. 
	  NyBit is now defined as Py_intptr_t and limits are calculated
	  a'la pyport.h .

	* src/sets/bitset.h: using __LP64__ macro to indirectly define internal
	  conditional flags, NyBits_32 resp. NyBits_64
	
	*  guppy/heapy/__init__.py : checked sys.maxint to detmine arch
	   some size-dependent tests are relaxed if not 32-bit arch
	*  guppy/heapy/test_heapyc.py : relaxed a timing test
	
	* src/sets/nodeset.c &c. changed some more occurences of int to NyBit
	  or perhaps they just became long in some place.

2008-03-13  Sverker Nilsson  <sverker@sverker-laptop>
	*  Starting modifications to work with 64 bits.
	*  guppy/src/sets/ (bitset.h, nodeset.c, bitset.c), maybe others,
	changes to especially the index type used as bit number in bitsets.
	Defining type NyBit for this and also NySize. They are just
	longs right now. Testing with Ubuntu 7.10 / AMD 64. 

2007-02-16  Sverker Nilsson  <sverker@localhost>

	* Put it under svn. Changed to call it 0.1.7 in README and ANNOUNCE

2007-01-31  Sverker Nilsson  <sverker@localhost>

	* guppy/gsl/XHTML.py (Node2XHTML.visit_comment): Made it not
	output anything to the XHTML file.

2007-01-25  Sverker Nilsson  <sverker@localhost>

	* guppy/gsl/Document.py (_GLUECLAMP_.output_handlers): Added XHTML entry
	(Document.visit_output): Made the output mode specification case-insensitive.

	* guppy/gsl: Added XHTML.py module - initially a copy of Html.py.
	I am changing to be more conventional(?) - to use all upper case
	in the XHTML name since that is how it is written looks in
	documents on the web. (Is this contrary to Python conventions to
	use Capitalized names?) But it would be too weird to write Xhtml
	(or even worse XHtml) vs XHTML. 
	
2006-11-08  Sverker Nilsson  <sverker@localhost>

	* guppy/gsl/Html.py (Node2Html.__init__): Changed (default,
	still fixed) encoding to utf-8.


	Version 0.1.6
	
2006-10-13  Sverker Nilsson  <sverker@localhost>

	* guppy/heapy/Use.py (_GLUECLAMP_._get_Root): This is what the
	method should have been called, not get_RS that it became
	yesterday.

	Version 0.1.5
	
2006-10-12  Sverker Nilsson  <sverker@localhost>

	* guppy/gsl/Document.py: Made some changes wrt dl/dt/dd to make
	the generated HTML code be more standards compliant, fixing
	rendering problems occuring AFAIK at least using Firefox.
	
	* guppy/gsl/Html.py: Fixed a problem with generated comments.
	
	* guppy/heapy/Remote.py (on): Made the site module be imported
	before Remote, to make it work in a normal installation when
	PYTHONPATH does not contain the guppy package. Had to change the
	recursion stopping flag to not be in the Remote module; now put in
	sys.

	(Annex) made h be a shorthand for hp in the remote interpreter, to
	be consistent with new abridged example style.
	
	* guppy/heapy/UniSet.py: Made sp be a shorthand for shpaths,
	because it is such a commonly used attribute.
	
	* guppy/heapy/[test_Path,test_ER].py : Made check of test results
	fit changes made to Path.py resp. Use.py
	
	* guppy/heapy/Use.py : Added RS attribute, to work with changes
	in Path.py. Changed default reprefix to be 'hpy().' , to be more
	meaningful in most cases.
	
	* guppy/heapy/Path.py (_GLUECLAMP_.shpgraph): Made the source name
	be derived from the Root attribute of the global hpy() instance in
	the normal case when the root is RootSTate -- to describe the path
	unambiguosly and show how it may be used.

	Version 0.1.4
	
2006-10-11  Sverker Nilsson  <sverker@localhost>

	* guppy/heapy/View.py (obj_at): Uses new obj_at method in
	immnodeset objects, to handle compatibility issues between Python
	versions and also be much faster.

	(referrers): After updating referrers, now checks that the domain
	of referrer graph was really covering the objects it should, and
	otherwise prints an error message and calls the debugger. -- I
	don't know when this should happen, the problem might have been
	due to a compilation version error, but I am letting the check
	left in.
	
	* guppy/etc/Glue.py: Checked ImportError message to see if it was
	a clean ImportError (No module named %s) in which case it proceeds
	as usual but otherwise the error is reported (showing the cause of
	the error)

	Changed '0x%x' to hex() to get rid of a compatibility warning
	
	Added more informative message text when an AttributeError is
	raised from getting an attribute from a module.
	
	* src/heapy/stdtypes.c (frame_relate): Replaced use of f_nlocals,
	f_ncells and f_nfreevars with values calculated from tuple sizes
	and co_nlocals, because in 2.5 the fields are removed in frames.
	(frame_traverse): Similarly removed use of f_nlocals.
	
	(type_traverse and type_relate): Changed name of slots to ht_slots
	if Python version >= 2.5.

	* src/sets/bitset.c: Removed use of type intintargfunc which is
	depreciated in Python2.5. 

	* src/sets/immnodeset.c: Added obj_at method to immutable
	nodesets, to solve problems occuring when using id() in different
	versions of Python (2.5 sometimes returns long ints) in the obj_at
	method in View.py; the C method is cleaner and much faster based
	on binary search.

	* src/sets/nodeset.c: Made a pointer comparison compare cast to
	Py_uintptr_t instead of pointers directly, to be more well defined
	since the pointers are to different objects.
	Removed the use of type intintargfunc which is depreciated in
	Python2.5. 


2006-10-09  Sverker Nilsson  <sverker@localhost>

	* guppy/heapy/test/test_Classifiers.py: Increased the number of
	loops in a time test from 10 to 100 to get better precision on
	faster machines. Removed a few tests that failed in newer Python
	depending on different object representation. Changed the use of 
	er.classifier.partition(li.nodes) to li.by(er).partition to make
	a testcloser to what would be used by the user. Added a debug
	parameter to test_main.
	
	* guppy/heapy/test/test_ER.py: Removed / commented out the many
	printouts, added missing tests when feasible, changed assert
	statements to self.assert_ calls, changed initial comments in test
	methods to doc strings to make test printout more informative.
	

	* guppy/heapy/test/test_heapyc.py: Removed some timing
	printouts. I think I could add some tests there instead but it is
	tricky to be portable and stable.
	

	* guppy/heapy/test/test_Path.py (chkrel): Made it handle the case
	where several relation edges were found, despite only one was
	originally expected, because this happened because of sharing
	introduced (likely by some optimization) in Python 2.5. Added
	debug parameter to test_main and run_test.

	* guppy/heapy/test/Use.py: Added test() method which will test all
	of heapy - easier to remember and write than ... whatever I had to
	write before.
	
2006-10-05  Sverker Nilsson  <sverker@localhost>

	* guppy/heapy/Classifiers.py: Uses str2int for conversion to
	handle differences between Python versions.

	* guppy/etc/etc.py: Added str2int function to have a single place
	to handle conversion of (hexadecimal) strings to integers - as it
	became more complicated when handling all Python versions 2.3 -
	2.5.

	
2006-10-02  Sverker Nilsson  <sverker@localhost>
	
	* guppy/gsl/SpecNodes.py: Added get_arg method. Changed a use of 0
	to False for clarity. Corrected context handling in
	errmsg_context. Made get_line open a read from a file when
	possible. 
	
2006-07-21  Sverker Nilsson  <sverker@localhost>

	* Changed the comment in docexample so as to show that comments do
	not need to have .c at the beginning of each line.
	( Noting that the generated document seems a bit 'naked' can use
	some more heading and some back-link to top, next etc.

2006-06-22  Sverker Nilsson  <sverker@localhost>

	* In gsl/Html.py, generalized the handling of header tags
	to allow for spec of links. Added charset specification
	to comply with W3C tests.

	Version 0.1.3
	
2006-03-02  Sverker Nilsson  <sverker@localhost>

	* In View, changed usage ArgSet -> Kind

2006-02-17  Sverker Nilsson  <sverker@localhost>

	* In Remote.py, changed the on() function to not do anything if it
	was called from within the annex thread itself. Changed RM.py to
	NOT do this check. (Structural/implementation cleanup details.)

	* In UniSet, changed name ArgSet -> Kind
	  (Implementation / documentation detail)

2006-02-14  Sverker Nilsson  <sverker@localhost>

	* Fixed bug with array sizing for Python 2.4 (in stdtypes.h)
	  Added test for this case (to test_View.py)
	
2006-02-07  Sverker Nilsson  <sverker@localhost>

	*  Added type_traverse to stdtypes
	   because the GC one didnt work with 2.4.2 in debug mode 
	   (It checked for heap type with assert.)
	* Changed usages of '0x%x'%addr to hex(addr) to make valid
	  hex literals in Python2.4.

2006-02-06  Sverker Nilsson  <sverker@localhost>

	* Added Monitor command to interrupt the remote process.
	  (The ki command.) It can still not interrupt it at all times.

	* Made end of file exit the monitor. (Otherwise may be infinite
	  loop for file input)

	* Made Monitor use threading rather than thread because the
	  program exited more cleanly in newer Pythons for some reason.
	
	
2006-02-05  Sverker Nilsson  <sverker@localhost>

	* Reverted the change to heapg but added a depreciated warning
	* Added the heapu method - a slightly better name
	  It finds the referred objects i.e. strings as well
	* Made the representation of a Stat indicate itself as such
	  to differentiate from repr of sets.
	* Made the sort order of stat diff be what it claimed (largest
	first)
	* Fixed Monitor so it passes empty commands along
	  so multi-line commands can be used in remote interpreter.
	* Changed the command string for quitting an interactive console
	  since 'q' is valid syntax
	  changed to: '-'
	
2006-02-03  Sverker Nilsson  <sverker@localhost>
	
	* Added priming of list and tuple iterators
	  so their slot wrappers dont suddenly show up unreachable.
	* Made heapg return just  .byclass.stat
	  to safeguard against common subtle problems.
	* Added one-time initialization in View.heap
	* Added ref option to reference pattern creator
	* Dropped the usage of 'observation containers' in heapg
	  since it is too brittle.
	* Uncommented call to deletecommand in fixed Menu in Prof.py
	* Added dump method to IdentitySet
	* Added Use.setrel
	
2006-02-01  Sverker Nilsson  <sverker@localhost>

	* Made help text of get_rp use shorter lines and added some
	  missing help text. Wrapped some other program lines.
	* Stopkind in rp should be independent on classifier
	  try eg using er=h.Type. Change to RefPat.
	
2006-01-23  Sverker Nilsson  <sverker@localhost>

	* Added some comments to C code (heapdef.h)

	Primary Bugs

	* Fixed a pointer comparison bug in nodegraph.c ,
	  which made a test fail in my new system
	  (with Linux 2.6.12-9-386) and could effect the outcome
	  of algorithms such as the shortest path.

	* Fixed the address comparison in View.obj_at so it
	  handles unsigned addresses.

	Test Portability Issues

	* Made test_via in test_Classifiers work in Python 2.4
	  getting around the optimization of tuple constants.
	* Relaxed guppy.heapy.test.test_Classifiers.RenderCase
	  since it was picky and list size changed in Python 2.4 .
	* Relaxed test_Path.test_nodeset_relation
	  since it wasn't portable across different kernel versions.
	* Fixed a test bug in sets/test.py where the range
	  step became zero with faster=0.
