Annotation of /branches/WIP-pyshapelib-bramz/libraries/pyshapelib/ChangeLog

2007-03-29      Bram de Greve <[email protected]>

        * shapelibmodule.c, dbflibmodule.c, pyshapelib_common.h: added support for
        Win32 wide character file API.  Unicode filenames are now fully supported
        on the windows platform: for example exotic filenames like the greek letter
        pi (u"\u03c0").  This is mostly mimicked from Python's fileobject.c, and
        needed some severe changes in the C++ shapelib library to support the wide
        filename API.  All XOpen and XCreate functions now have XOpenW and XCreateW
        counterparts plus some common code has been split to XOpenEx and XCreateEx.
        I hope these modifications might one day end up in an official shapelib
        release.  Meanwhile, compatibility is guaranteed as the specific Unicode
        code paths are not compiled if the modifications are not found.

2007-03-22      Bram de Greve <[email protected]>

        * shapelibmodule.c, dbflibmodule.c: in __init__ of ShapeFile and DBFFile,
        throw proper IOError if opening of file failed.
        
        * dbflibmodule.c: commit function was incorrectly pointing to 
        dbflib_read_record

2007-03-21      Bram de Greve <[email protected]>

        * shptreemodule.c: restoring something that shouldn't have been committed.

2007-03-15      Bram de Greve <[email protected]>

        * shapelib.c: When creating measured shapes (XYM), treat M value
        value as optional (defaults to zero).  Similar for
        3D shapes (XYZM), threat both the Z and M value as options 
        (both default to zero).  When M values are to be given,
        None is accepted as "no-data" value, and is stored as zero
        (ESRI shapefile specs define any M value smaller than 1e-38
        as no-data). Added an unpack_vertex() function to lift some
        of the load of shpobject_init. Fixed a missing break and
        PyMem_Free in build_vertex_list(), shapefile_init() and
        shapelib_create().

        * dbflibmodule.c: Added support for the FTLogical field type.
        
        * shapelibmodule.c, dbflibmodule.c: Added 'name' and 'mode' 
        keywords for ShapeFile and DBFFile constructors and the module's
        open() function, similiar to Python's file().  Reformatted 
        the doc strings to have a standard look and feel when parsed
        through pydoc.
        
        * shapelib_common.h: added no-data constants.
        
        * pytest.py: Added tests for multipatch shapefile with XYZM values.
        Added tests for FTLogical field.

2007-03-15      Bram de Greve <[email protected]>

        * shapelibmodule.c, dbflibmodule.c: added some Unicode support for the
        filenames (no internal encoding for DBFFile yet).  It now should similar
        Unicode support Python's file() (concerning the filename, that is).

2007-03-14  Bram de Greve <[email protected]>

        * shapelibmodule.c: added support for shapetypes with Z and M values

2007-03-14  Bram de Greve <[email protected]>

        * dbflibmodule.c, dbflib.i: replaced dbflib.i by dbflibmodule.c to use
        hand-crafted Python bindings instead of SWIG generated ones
        
        * shapelibmodule.c, shapelib.c: Renamed shapelib.c to shapelibmodule.c
        to match style of dbflibmodule.c and shptreemodule.c.  Changed some
        (well, most) names to match same style.
        
        * pyshapelib_common.h: do all necessary includes here
        
        * setup.py: updated building of dbflib.
        
2007-03-13  Bram de Greve <[email protected]>

        * shapelib.c, shapelib_common.h: Added part_types() to SHPObject to
        return tuple of part types. Added __repr__ operators to return a 
        string that can reconstruct the object using eval()
        
        * pytest.py: Added tests for part_types() and __repr__.  
        Humanized the output a bit.

2007-03-12  Bram de Greve <[email protected]>

        * shapelib.c, shapelib.i: replaced shapelib.i by shapelib.c to use 
        hand-crafted Python bindings instead of SWIG generated ones.
        
        * pyshapelib_common.h: New file with some common stuff for both 
        shapelib and dbflib
        
        * pyshapelib_api.h, setup.py: import/build shapelib instead of shapelibc
        
2006-09-24  Bernhard Reiter  <[email protected]>

        * dbflib_wrap.c, README: Checked for python version >= 2.4.0a0
        before using &PyOS_ascii_atof.

2006-09-24  Bernhard Reiter  <[email protected]>

        Added dirty workaround to make dbflib agnostic 
        against decimal_poinst != ".\0".

        * dbflib_wrap.c: Added call DBFSetatof_function(&PyOS_ascii_atof);
        to initdbflibc(). 
        * README: noted that manual editing of dbflib_wrap.c is necessary now.

2005-06-30  Bernhard Herzog  <[email protected]>

        * shapelib.i (new_SHPObject): Fix the test for the length of the
        part types.  It used the wrong variable.

        * shapelib_wrap.c: Regenerated from shapelib.i

        * pytest.py (make_shapefile): Add some more comments and add an
        example with a polygon with a hole.

2004-12-27  Bernhard Reiter  <[email protected]>
        
        * README: Refering to the new homepage shapelib.maptools.org now.

2004-12-13  Bernhard Herzog  <[email protected]>

        * dbflib.py: Updated from difflib.i with SWIG.

        * dbflib.i: Work around a bug in the generated python code which
        leads to exception in the __del__ method when the constructor
        fails.  See the comments in the code for more details.

2004-05-28  Bernhard Herzog  <[email protected]>

        * README: Flesh out the some more.  Correct the shapelib
        requirements.

        * NEWS: Update the date of the actual release of 0.3

2004-05-28  Bernhard Herzog  <[email protected]>

        * setup.py: Determine shp_dir correctly when run with bdist_rpm
        (dbf_macros): Remove a debug print

        * NEWS: Also mention the new (compared to 0.2) setup.py

        * MANIFEST.in: New. Define which files belong into a source
        distribution

2004-05-17  Bernhard Herzog  <[email protected]>

        * README: Update for new release

        * setup.py (dbf_macros): New. Return the preprocessor macros
        needed to compile the dbflib wrapper.  Determine whether
        DBFUpdateHeader is available and define the right value of
        HAVE_UPDATE_HEADER
        (extensions): Use dbf_macros for the dbflibc extension

        * dbflib_wrap.c, dbflib.py: Update from dbflib.i

        * dbflib.i (DBFInfo_commit): New. Implementation of the commit
        method.  This new indirection is necessary because we use the
        DBFUpdateHeader function now which is not available in shapelib <=
        1.2.10
        (DBFFile::commit): Use DBFInfo_commit as implementation
        (pragma __class__): New. Kludge to remove the commit method when
        the DBFUpdateHeader function isn't available
        (_have_commit): New. Helper for the pragma kludge.

2003-11-03  Bernhard Herzog  <[email protected]>

        * dbflib.i (do_read_attribute): New helper function for reading
        one attribute as a python object
        (DBFInfo_read_attribute): New. Implement the read_attribute method

        individual values
        (struct DBFFile): Add the read_attribute method.

        * dbflib_wrap.c, dbflib.py: Update from dbflib.i.

2003-09-29  Bernhard Herzog  <[email protected]>

        * testdbf.py: New. Test cases for the dbflib bindings based on the
        unittest module

2003-08-18  Bernhard Herzog  <[email protected]>

        * dbflib.i (DBFInfo_write_record): Use PySequence_Check instead of
        PyMapping_Check to distinguish between sequences and mappings
        because in Python 2.3, PyMapping_Check returns true for tuples and
        lists too.

2003-05-28  Bernhard Herzog  <[email protected]>

        * dbflib.i (DBFInfo_read_record): Read NULL fields as None unless
        it's a string field. DBF files can't distinguish between NULL and
        an empty string. Also, check the return value of
        DBFReadStringAttribute which may return NULL to indicate errors.

        * dbflib_wrap.c: Updated from dbflib.i

2002-08-27  Bernhard Herzog  <[email protected]>

        * dbflib.i: Raise an exception if open or create fails.

        * shapelib.i: Slightly better wording for the IOError exception
        that open and create may raise.

        * shapelib_wrap.c, dbflib_wrap.c: Regenerated

2002-08-22  Bernhard Herzog  <[email protected]>

        * dbflib.i (DBFFile::commit): New method for DBFCommit.

        * dbflib_wrap.c, dbflib.py: Update from dbflib.i

2002-08-15  Bernhard Herzog  <[email protected]>

        * shapelib.i, dbflib.i: Make the NOCHECK trick for the ShapeFile *
        check typemap work with SWIG 1.3.

        * shapelib_wrap.c, dbflib_wrap.c: Regenerate from the .i files.

2002-05-10  Bernhard Herzog  <[email protected]>

        * dbflib.i (DBFInfo_write_record): Only DECREF if the return value
        of PyMapping_GetItemString is not NULL. Also, test the return
        value of PySequence_GetItem
        (write_field): Remove some debug prints

        * dbflib_wrap.c: Updated from dbflib.i

2002-05-07  Bernhard Herzog  <[email protected]>

        * shptreemodule.c (SHPTreeType, initshptree): Set SHPTreeType's
        PyType_Type pointer in the init function.
        (shptree_methods): Use METH_VARARGS
        (shptree_dealloc): Use PyMem_DEL
        (shptree_find_shapes): Add a missing return

2002-05-07  Bernhard Herzog  <[email protected]>

        * shptreemodule.c: New file with a simple wrapper for shapelib's
        quadtree

        * setup.py: Some fixes to use explicit forward slashes as
        directory separators because of distutils.
        (extensions): Add the shptree module.

        * pytest.py (read_shapefile): Add some demo calls for the shptree
        module

        * pyshapelib_api.h (PyShapeLibAPI): Add some of the shptree
        functions.
        (PYSHAPELIB_IMPORT_API): New macro to import the API

        * shapelib.i (the_api): add the tree API functions.

        * shapelib_wrap.c: Updated from shapelib.i with SWIG.

2002-04-11  Bernhard Herzog  <[email protected]>

        * pyshapelib_api.h: New file with a limited C-level API for
        accessing shapilib functions from other Python-extensions.

        * shapelib.i: Export the C-level API with the c_api function.

        * shapelib.py, shapelib_wrap.c: Updated from shapelib.i. Still
        done with a very old version of SWIG, but it's probably not worth
        it to try it with a newer version as long as this still works.

2001-07-18  Bernhard Herzog  <[email protected]>

        * shapelib.i (open_ShapeFile): declare the swig prototype
        correctly with ShapeFile* as return type
        (ShapeFile.cobject): New method returning the SHPHandle* as a
        CObject

        * Makefile (VERSION): Increase to 0.3

        * setup.py, MANIFEST.in: New files for python distutils. 

2001-06-15  Bernhard Herzog  <[email protected]>

        * Makefile (VERSION): Increase to 0.2

2001-06-14  Bernhard Herzog  <[email protected]>

        * shapelib.i: Add the functions SHPTypeName as type_name and
        SHPPartTypeName as part_type_name
        (SHPObject_vertices):
        (build_vertex_list): Put building a list of vertices into the
        separate function build_vertex_list so that SHPObject_vertices can
        support SHPT_POINT too.

        * ChangeLog: create ChangeLog

199			it's a string field. DBF files can't distinguish between NULL and
200			an empty string. Also, check the return value of
201			DBFReadStringAttribute which may return NULL to indicate errors.
202
203			* dbflib_wrap.c: Updated from dbflib.i
204
205			2002-08-27 Bernhard Herzog <[email protected]>
206
207			* dbflib.i: Raise an exception if open or create fails.
208
209			* shapelib.i: Slightly better wording for the IOError exception
210			that open and create may raise.
211
212			* shapelib_wrap.c, dbflib_wrap.c: Regenerated
213
214			2002-08-22 Bernhard Herzog <[email protected]>
215
216			* dbflib.i (DBFFile::commit): New method for DBFCommit.
217
218			* dbflib_wrap.c, dbflib.py: Update from dbflib.i
219
220			2002-08-15 Bernhard Herzog <[email protected]>
221
222			* shapelib.i, dbflib.i: Make the NOCHECK trick for the ShapeFile *
223			check typemap work with SWIG 1.3.
224
225			* shapelib_wrap.c, dbflib_wrap.c: Regenerate from the .i files.
226
227			2002-05-10 Bernhard Herzog <[email protected]>
228
229			* dbflib.i (DBFInfo_write_record): Only DECREF if the return value
230			of PyMapping_GetItemString is not NULL. Also, test the return
231			value of PySequence_GetItem
232			(write_field): Remove some debug prints
233
234			* dbflib_wrap.c: Updated from dbflib.i
235
236			2002-05-07 Bernhard Herzog <[email protected]>
237
238			* shptreemodule.c (SHPTreeType, initshptree): Set SHPTreeType's
239			PyType_Type pointer in the init function.
240			(shptree_methods): Use METH_VARARGS
241			(shptree_dealloc): Use PyMem_DEL
242			(shptree_find_shapes): Add a missing return
243
244			2002-05-07 Bernhard Herzog <[email protected]>
245
246			* shptreemodule.c: New file with a simple wrapper for shapelib's
247			quadtree
248
249			* setup.py: Some fixes to use explicit forward slashes as
250			directory separators because of distutils.
251			(extensions): Add the shptree module.
252
253			* pytest.py (read_shapefile): Add some demo calls for the shptree
254			module
255
256			* pyshapelib_api.h (PyShapeLibAPI): Add some of the shptree
257			functions.
258			(PYSHAPELIB_IMPORT_API): New macro to import the API
259
260			* shapelib.i (the_api): add the tree API functions.
261
262			* shapelib_wrap.c: Updated from shapelib.i with SWIG.
263
264			2002-04-11 Bernhard Herzog <[email protected]>

267			accessing shapilib functions from other Python-extensions.
268
269			* shapelib.i: Export the C-level API with the c_api function.
270
271			* shapelib.py, shapelib_wrap.c: Updated from shapelib.i. Still
272			done with a very old version of SWIG, but it's probably not worth
273			it to try it with a newer version as long as this still works.
274
275			2001-07-18 Bernhard Herzog <[email protected]>
276
277			* shapelib.i (open_ShapeFile): declare the swig prototype
278			correctly with ShapeFile* as return type

292			* shapelib.i: Add the functions SHPTypeName as type_name and
293			SHPPartTypeName as part_type_name
294			(SHPObject_vertices):
295			(build_vertex_list): Put building a list of vertices into the
296			separate function build_vertex_list so that SHPObject_vertices can
