fiona

Bug fixes:

• Opening a data file in read (the default) mode with fiona.open() using the the driver or drivers keyword arguments (to specify certain format drivers) would sometimes cause a crash on Windows due to improperly terminated lists of strings (#428). The fix: Fiona's buggy string_list() has been replaced by GDAL's CSLAddString().

Bug fixes:

• OGR's EsriJSON detection fails when certain keys aren't found in the first 6000 bytes of data passed to BytesCollection (#422). A .json file extension is now explicitly given to the in-memory file behind BytesCollection when the driver='GeoJSON' keyword argument is given (#423).

Roses are red. Tan is a pug. Software regression's the most embarrassing bug.

Bug fixes:

• Use __stdcall for GDAL error handling callback on Windows as in Rasterio.
• Turn on latent support for zip:// URLs in rio-cat and rio-info (#421).
• The 1.7.2 release broke support for zip files with absolute paths (#418). This regression has been fixed with tests to confirm.

Future Deprecation:

• Collection.__next__() is buggy in that it can lead to duplication of features when used in combination with Collection.filter() or Collection.__iter__(). It will be removed in Fiona 2.0. Please check for usage of this deprecated feature by running your tests or programs with PYTHONWARNINGS="always:::fiona" or -W"always:::fiona" and switch from next(collection) to next(iter(collection)) (#301).

Bug fix:

• Zipped streams of bytes can be accessed by BytesCollection (#318).

• New binary wheels using version 1.2.0 of sgillies/frs-wheel-builds. See https://github.com/sgillies/frs-wheel-builds/blob/master/CHANGES.txt.

Bug Fixes:

• Prevent Fiona from stumbling over 'Z', 'M', and 'ZM' geometry types introduced in GDAL 2.1 (#384). Fiona 1.7.1 doesn't add explicit support for these types, they are coerced to geometry types 1-7 ('Point', 'LineString', etc.)
• Raise an UnsupportedGeometryTypeError when a bogus or unsupported geometry type is encountered in a new collection's schema or elsewhere (#340).
• Enable --precision 0 for fio-cat (#370).
• Prevent datetime exceptions from unnecessarily stopping collection iteration by yielding None (#385)
• Replace log.warn calls with log.warning calls (#379).
• Print an error message if neither gdal-config or --gdalversion indicate a GDAL C API version when running setup.py (#364).
• Let dict-like subclasses through CRS type checks (#367).

Packaging: define extension modules for 'clean' and 'config' targets (#363).

Packaging: No files are copied for the 'clean' setup target (#361, #362).

The C extension modules in this library can now be built and used with either a 1.x or 2.x release of the GDAL library. Big thanks to René Buffat for leading this effort.

Refactoring:

• The ogrext1.pyx and ogrext2.pyx files now use separate C APIs defined in ogrext1.pxd and ogrex2.pxd. The other extension modules have been refactored so that they do not depend on either of these modules and use subsets of the GDAL/OGR API compatible with both GDAL 1.x and 2.x (#359).

Packaging:

• Source distributions now contain two different sources for the ogrext extension module. The ogrext1.c file will be used with GDAL 1.x and the ogrext2.c file will be used with GDAL 2.x.

• Raise ImportError if the active GDAL library version is >= 2.0 instead of failing unpredictably (#338, #341). Support for GDAL>=2.0 is coming in Fiona 1.7.

• No changes to the library in this post-release version, but there is a significant change to the distributions on PyPI: to help make Fiona more compatible with Shapely on OS X, the GDAL shared library included in the macosx (only) binary wheels now statically links the GEOS library. See https://github.com/sgillies/frs-wheel-builds/issues/5.

• Daytime has been decreasing in the Northern Hemisphere, but is now increasing again as it should.
• Non-UTF strings were being passed into OGR functions in some situations and on Windows this would sometimes crash a Python process (#303). Fiona now raises errors derived from UnicodeError when field names or field values can't be encoded.

• Providing only PROJ4 representations in the dataset meta property resulted in loss of CRS information when using the fiona.open(..., **src.meta) as dst pattern (#265). This bug has been addressed by adding a crs_wkt item to themeta property and extending thefiona.open()` and the collection constructor to look for and prioritize this keyword argument.

• Bug fix: Fiona now deserializes JSON-encoded string properties provided by the OGR GeoJSON driver (#244, #245, #246).
• Bug fix: proj4 data was not copied properly into binary distributions due to a typo (#254).
