GDAL/OGR 2.4.1 Release Notes

The 2.4.1 release is a bug fix release.

Build

Unix:

• Fix build with OpenBSD which doesn't support RLIMIT_AS (#1163)
• fix build --without-lerc (#1224)
• configure: fix netcdf_mem.h detection in netcdf 4.6.2 (#1328)

Windows:

• Fix build issue for builds without curl (#1251)
• nmake.opt: remove unicode character at line starting with '# 4275' that apparently cause build issues with some MSVC versions (#1169)

All:

• Poppler: revision version management. Drop support for ancient versions older than 0.23.0
• Add support for Poppler 0.72.0 and 0.73.0 (#1207, #1208)

Port

• cpl_vsi.h: fix include for C use
• VSICurlHandle::ReadMultiRange(): use default implementation if there is a single range. May help to improve performance for #1206
• VSIGZipWriteHandleMT: avoid potential deadlock in case of error
• /vsihdfs/: fix Read() when more than one hdfsRead call is needed (#1349)

GDAL utilities

• gdalwarp -crop_to_cutline: do not round computed target extent to be aligned on the grid of the source raster if -tr is set (restore partially pre 2.4 behaviour) (#1173)
• gdalwarp: assume -tap when using -crop_to_cutline, -tr and -wo CUTLINE_ALL_TOUCHED=TRUE, so as to avoid issues with polygons smaller than 1x1 pixels (#1360)
• gdal2tiles: give local tile layer and basemap layers same min/max zoom levels as generated tile cache (#1074)
• gdal2tiles: fix breakage of openlayers.html getURL() javascript function, introduced in GDAL 2.3.3 / 2.4.0 (#1127)
• gdal2tiles: prevent accidental copy of full GeoTIFF into temporary .vrt file
• Fix double-free in StripIrrelevantOptions() (triggered by gdalinfo / ogrinfo --format)
• gdal_retile.py: use nodata value from origin dataset

GDAL algorithms

• rasterize: fix crash when working buffer is larger than 2GB (#1338)

GDAL drivers

COSAR driver:

• avoid out-of-bound write on corrupted dataset. Fixes OSS Fuzz #12360

GTiff driver:

• only report scale/offset deduced from ModelTiepointTag and ModelPixelScaleTag if the SRS has a vertical component (and thus currently if GTIFF_REPORT_COMPD_CS is set) (​https://issues.qgis.org/issues/20493)
• Lerc codec: properly initialize state after Create() so that BuildOverviews() succeed (#1257)

KMLSuperOverlay driver:

• report color table of single overlay datasets, and also handle some variation in the KML structure (​https://issues.qgis.org/issues/20173)

JPEG driver:

• fix GDAL 2.3.0 performance regression when decoding JPEG (or GPKG using JPEG) images (#1324)

netCDF driver:

• fix crash when opening a dataset with an attribute of length 0 (#1303)

PDSv3 driver:

• fix decoding of band interleaved images (such as for CRISM HSP) (#1239)

XPM driver:

• fix read heap buffer overflow on corrupted image. Fixes OSS Fuzz #13455

OGR core

• Polyhedral surface: fix importFromWKT to properly fix Z/M flag
• OGRGeometryFactory::GetCurveParmeters(): fix assertion when coordinates are very near 0 (relates to OSS Fuzz #13408)
• OGRLineString::segmentize(): fix issues when segment length is divisible by maxlength (#1341)

OGRSpatialReference

• Coordinate transformation: do not apply +towgs84 if it is present only in one one of the CRS, when using PROJ >= 5 (#1156)

OGR drivers

CSW driver:

• fix crash when geometry parsing fails (#1248)

DXF driver:

• fix double-free issue in case of writing error. Fixes OSS Fuzz #13516

Elasticsearch driver:

• Fix index comparison bug when a index have at least one mapping

GeoJSON driver:

• speed-up random reading with GetFeature() to retrieve performance similar to GDAL 2.2 or before (​https://issues.qgis.org/issues/21085)

GeoPackage driver:

• allow srs_id with negative values

GML driver:

• write SRSName element in .gfs when parsing a GML file with srsName only on top-level boundedBy element (#1210)
• Add "FeatureType" to list of suffixes recognized by XSD parser for compatibility with schemas produced by ArcGIS Server
• Fix assertion in CPLGetValueType when testing non-ASCII chars

MITAB driver:

• .tab: fix deleting a feature without geometry (#1232)
• adapt dynamically default projection bounds to false_easting/false_northing values (#1316)
• avoid potential assertion or stack buffer overflow on corrupted .ind files. Fixes OSS Fuzz #11999.
• prevent potential infinite recursion on broken indexes. Fixes OSS Fuzz #12739.

MSSQLSpatial driver:

• Add option to expose the FID column as a feature attribute (#1227)

ODS driver:

• allow opening tables with empty cells with huge values of columns-repeated attribute at end of line (#1243)
• aavoid potential null pointer dereference when writing to corrupted filename. Fixes OSS Fuz #12976.

PDF driver:

• avoid division by zero when generating from vector content whose bounding box is almost a horizontal or vertical line. Fixes OSS Fuzz #13408

PGDump driver:

• emit correct SQL statement when UNLOGGED=ON

Selafin driver:

• avoid null pointer dereference on corrupted files. Fixes OSS Fuzz #12356

VFK driver:

• fix regression where curved geometries were ignored (#1351)

Python bindings

• fix Dataset.ReadAsRaster() on CInt16 data type (#1186)
