GDAL/OGR 2.3.3 Release Notes

The 2.3.3 release is a bug fix release.

Build

Unix:

• fix potential link errors when using internal libgif and internal libpng but headers of those libraries are available in the system in different versions than our internal ones (#938)

All:

• Add support for Poppler 0.69 (#1004) and 0.71 (#1121)

Port

• /vsiaz/: support BlobEndpoint element in AZURE_STORAGE_CONNECTION_STRING such as found in Azurite (#957)
• /vsis3/: detect Amazon EC2 instances that use the newer hypervisor (#958)
• /vsis3/: honour CPL_VSIL_CURL_ALLOWED_EXTENSIONS configuration option (#995)
• /vsicurl/: fix parsing of HTML file listing that got broken in GDAL 2.3.0

GDAL utilities

• gdalwarp: fix crash when warping on an existing dataset with less bands as needed
• gdal2tiles: rename 'tilesize' and 'tileSize' variables to 'tile_size' to have uniform spelling, and fix exception (#1127)
• gdal_grid: fix -clipsrc from a vector datasource (broken at least since GDAL 2.1)

GDAL algorithms

• gdal_grid linear: fix detection of degenerate triangles (#973)

GDAL drivers

FITS driver:

• allow reading/writing beyond 2 billion pixel limit

GeoRaster driver:

• Fix the issue by freeing the temporary lobs created by readCLob() and writeCLOB().

GPKG driver:

• properly delete gridded coverage raster layers

GRIB driver:

• interpret missing data values correctly for complex packing when original data is integer (#1063)
• fix writing of nodata value for complex value when original data is integer (#1063)
• add UNIT[] node to SRS on reading, so that is valid

GTiff driver:

• update COMPRESSION_ZSTD to the new value of 50000. Still recognize files created with 34926, but only in the branch, and emit warning
• internal libtiff: tif_lzma.c: report error in LZMAPreEncode() which can require a lot of memory; and skip gracefully in tests in that case (#1026)

IRIS driver:

• add UNIT[] node to SRS on reading, so that is valid

NetCDF driver:

• fix west > east if west should be < east (#1114)

PDS4 driver:

• add UNIT[] node to SRS on reading, so that is valid

RasterLite2 driver:

• fail on Create() that is not supported

RDA driver:

• enable support for DG RDA Image Reference string

VRT driver:

• deal with serialized nodata value that is slightly outside Float32 validity range (#1071)

WMTS driver:

• fix issue with inappropriate zoom level being selected causing integer overflow in raster dimension computation
• fix potential off-by-one pixel when compositing the underlying WMS/TMS source into the final raster

OGR core

• SQLite dialect: fix when ROWID is used in WHERE clause and the source layer has a real FID column name
• GML geometry parser: recognize MultiGeometry.geometryMembers syntax (refs ​https://issues.qgis.org/issues/19571)

OGRSpatialReference

• FindMatches(): if the input SRS has a EPSG code, check that its definition and the EPSG one actually matches (#990)

OGR utilities

• ogr_merge.py: fix issue with non-ASCII characters (#1067)

OGR drivers

DXF driver:

• fix memory leak in case of attempt to write GeometryCollection of unsupported type. Fixes ​https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11516.

GeoJSON driver:

• RFC7946 writer: clip and offset geometries outside [-180,180] (#1068)

KML/LIBKML drivers:

• robustify for out-of-memory conditions (​https://issues.qgis.org/issues/19989)

LIBKML driver:

• make edition of existing file work (​https://issues.qgis.org/issues/18631)
• implement OGRLIBKMLLayer::SyncToDisk() to fix ​https://issues.qgis.org/issues/18631)
• workaround weird issue with OSGeo4W and newline characters in <coordinate> element (​https://issues.qgis.org/issues/19215)

MSSQLSpatial driver:

• Fix geometry parser with M values (#1051)

MVT driver:

• disable check on 'extent' field in identifiation method, which rejected tiles with extent > 16384

OpenFileGDB driver:

• fix potential crash on corrupted datasets. Fixes ​https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11313.

Shape driver:

• avoid being dependent on correctness of file size field in .shp. Fixes ​https://lists.osgeo.org/pipermail/gdal-dev/2018-October/049218.html

SQLite driver:

• do not run spatial index creation in rollback code

XLSX / ODS drivers:

• avoid harmless warning in some cases when guessing column data types

Python bindings

• avoid crash in ReadRaster() under low memory condition (#1026)
