2.10.0 - 2016-11-11

Added

• The Reader can take an additional optional read_meta flag. If this is set to false the PBF input will ignore metadata on OSM objects (like version, timestamp, uid, ...) which speeds up file reading by 10 to 20%.
• New IdSet virtual class with two implementations: IdSetDense and IdSetSmall. Used to efficiently store a set of Ids. This is often needed to track, for instance, which nodes are needed for ways, etc.
• Added more examples and better documented existing examples.
• Add a benchmark "mercator" converting all node locations in a file to WebMercator and creating geometries in WKB format.

Changed

• Better queue handling makes I/O faster in some circumstances.
• The FindOsmium.cmake CMake script can now check a current enough libosmium version is found.
• Builders can now be constructed with a reference to parent builder.
• Made builders more robust by adding asserts that will catch common usage problems.
• Calling OSMObjectBuilder::add_user() is now optional, and the method was renamed to set_user(). (add_user() is marked as deprecated.)
• Benchmarks now show compiler and compiler options used.
• Builder::add_item() now takes a reference instead of pointer (old version of the function marked as deprecated).
• GEOS support is deprecated. It does not work any more for GEOS 3.6 or newer. Reason is the changed interface in GEOS 3.6. If there is interest for the GEOS support, we can add support back in later (but probably using the GEOS C API which is more stable than the C++ API). Some tests using GEOS were rewritten to work without it.
• The BoolVector has been deprecated in favour of the new IdSet classes.
• Lots of code cleanups and improved API documentation in many places.
• The relations collector can now tell you whether a relation member was in the input data. See the new is_available() and get_availability_and_offset() methods.
• Updated embedded Catch unit test header to version 1.5.8.

Fixed

• Parsing of coordinates starting with decimal dot and coordinates in scientific notation.
• ~ operator for entity_bits doesn't set unused bits any more.
• Progress bar can now be (temporarily) removed, to allow other output.

2.9.0 - 2016-09-15

Added

• Support for reading OPL files.
• For diff output OSM objects in buffers can be marked as only in one or the other file. The OPL and debug output formats support diff output based on this.
• Add documentation and range checks to Tile struct.
• More documentation.
• More examples and more extensive comments on examples.
• Support for a progress report in osmium::io::Reader() and a ProgressBar utility class to use it.
• New OSMObject::set_timestamp(const char*) function.

Changed

• Parse coordinates in scientific notations ourselves.
• Updated included protozero version to 1.4.2.
• Lots of one-argument constructors are now explicit.
• Timestamp parser now uses our own implementation instead of strptime. This is faster and independant of locale settings.
• More cases of invalid areas with duplicate segments are reported as errors.

Fixed

• Fixed a problem limiting cache file sizes on Windows to 32 bit.
• Fixed includes.
• Exception messages for invalid areas do not report "area contains no rings" any more, but "invalid area".

2.8.0 - 2016-08-04

Added

• EWKT support.
• Track pop type calls and queue underruns when OSMIUM_DEBUG_QUEUE_SIZE environment variable is set.

Changed

• Switched to newest protozero v1.4.0. This should deliver some speedups when parsing PBF files. This also removes the DeltaEncodeIterator class, which isn't needed any more.
• Uses std::unordered_map instead of std::map in PBF string table code speeding up writing of PBF files considerably.
• Uses less memory when writing PBF files (smaller string table by default).
• Removes dependency on sparsehash and boost program options libraries for examples.
• Cleaned up threaded queue code.

Fixed

• A potentially very bad bug was fixed: When there are many and/or long strings in tag keys and values and/or user names and/or relation roles, the string table inside a PBF block would overflow. I have never seen this happen for normal OSM data, but that doesn't mean it can't happen. The result is that the strings will all be mixed up, keys for values, values for user names or whatever.
• Automatically set correct SRID when creating WKB and GEOS geometries. Note that this changes the behaviour of libosmium when creating GEOS geometries. Before we created them with -1 as SRID unless set otherwise. Manual setting of the SRID on the GEOSGeometryFactory is now deprecated.
• Allow coordinates of nodes in scientific notation when reading XML files. This shouldn't be used really, but sometimes you can find them.

2.7.2 - 2016-06-08

Changed

• Much faster output of OSM files in XML, OPL, or debug formats.

Fixed

• Parsing and output of coordinates now faster and always uses decimal dot independant of locale setting.
• Do not output empty discussion elements in changeset XML output.
• Data corruption regression in mmap based indexes.

2.7.1 - 2016-06-01

Fixes

• Update version number in version.hpp.

2.7.0 - 2016-06-01

Added

• New functions for iterating over specific item types in buffers (osmium::memory::Buffer::select()), over specific subitems (osmium::OSMObject::subitems()), and for iterating over all rings of an area (osmium::Areas::outer_rings(), inner_rings()).
• Debug output optionally prints CRC32 when add_crc32 file option is set.

Changed

• XML parser will not allow any XML entities which are usually not used in OSM files anyway. This can help avoiding DOS attacks.
• Removed SortedQueue implementation which was never used.
• Also incorporate Locations in NodeRefs into CRC32 checksums. This means all checksums will be different compared to earlier versions of libosmium.
• The completely new algorithm for assembling multipolygons is much faster, has better error reporting, generates statistics and can build more complex multipolygons correctly. The ProblemReporter classes have changed to make this happen, if you have written your own, you have to fix it.
• Sparse node location stores are now only sorted if needed, ie. when nodes come in unordered.

Fixed

• Output operator for Location shows full precision.
• Undefined behaviour in WKB writer and types_from_string() function.
• Fix unsigned overflow in pool.hpp.
• OSM objects are now ordered by type (nodes, then ways, then relations), then ID, then version, then timestamp. Ordering by timestamp is normally not necessary, because there can't be two objects with same type, ID, and version but different timestamp. But this can happen when diffs are created from OSM extracts, so we check for this here. This change also makes sure IDs are always ordered by absolute IDs, positives first, so order is 0, 1, -1, 2, -2, ...
• Data corruption bug fixed in disk based indexes (used for the node location store for instance). This only affected you, if you created and index, closed it, and re-opened it (possibly in a different process) and if there were missing nodes. If you looked up those nodes, you got location (0,0) back instead of an error.
• Memory corruption bug showing up with GDAL 2.

2.6.1 - 2016-02-22

Added

• Add WITH_PROFILING option to CMake config. When enabled, this sets the -fno-omit-frame-pointer compiler option.

Changed

• Massive speed improvements when building multipolygons.
• Uses (and includes) new version 1.3.0 of protozero library.
• Removed dependency on Boost Iterator for PBF writer.
• Example program osmium_area_test now uses cerr instead of cout for debug output.

2.6.0 - 2016-02-04

Added

• The new handler osmium::handler::CheckOrder can be used to check that a file is properly ordered.
• Add new method to build OSM nodes, ways, relations, changesets, and areas in buffers that wraps the older Builder classes. The new code is much easier to use and very flexible. There is no documentation yet, but the tests in test/t/builder/test_attr.cpp can give you an idea how it works.
• Add util class to get memory usage of current process on Linux.

Changed

• New Buffer memory management speeds up Buffer use, because it doesn't clear the memory unnecessarily.

Fixed

• osmium::Box::extend() function now ignores invalid locations.
• Install of external library headers.
• Check way has at least one node before calling is_closed() in area assembler.
• Declaration/definition of some friend functions was in the wrong namespace.

2.5.4 - 2015-12-03

Changed

• Included gdalcpp.hpp header was updated to version 1.1.1.
• Included protozero library was updated to version 1.2.3.
• Workarounds for missing constexpr support in Visual Studio removed. All constexpr features we need are supported now.
• Some code cleanup after running clang-tidy on the code.
• Re-added Buffer::value_type typedef. Turns out it is needed when using std::back_inserter on the Buffer.

Fixed

• Bugs with Timestamp code on 32 bit platforms. This necessitated some changes in Timestamp which might lead to changes in user code.
• Bug in segment intersection code (which appeared on i686 platform).

2.5.3 - 2015-11-17

Added

• osmium::make_diff_iterator() helper function.

Changed

• Deprecated osmium::Buffer::set_full_callback().
• Removed DataFile class which was never used anywhere.
• Removed unused and obscure Buffer::value_type typedef.

Fixed

• Possible overrun in Buffer when using the full-callback.
• Incorrect swapping of Buffer.

2.5.2 - 2015-11-06

Fixed

• Writing data through an OutputIterator was extremly slow due to lock contention.

2.5.1 - 2015-11-05

Added

• Header osmium/fwd.hpp with forward declarations of the most commonly used Osmium classes.

Changed

• Moved osmium/io/overwrite.hpp to osmium/io/writer_options.hpp If you still include the old file, you'll get a warning.

2.5.0 - 2015-11-04

Added

• Helper functions to make input iterator ranges and output iterators.
• Add support for reading o5m and o5c files.
• Option for osmium::io::Writer to fsync file after writing.
• Lots of internal asserts() and other robustness checks.

Changed

• Updated included protozero library to version 1.2.0.
• Complete overhaul of the I/O system making it much more robust against wrong data and failures during I/O operations.
• Speed up PBF writing by running parts of it in parallel.
• OutputIterator doesn't hold an internal buffer any more, but it uses one in Writer. Calling flush() on the OutputIterator isn't needed any more.
• Reader now throws when trying to read after eof or an error.
• I/O functions that used to throw std::runtime_error now throw osmium::io_error or derived.
• Optional parameters on osmium::io::Writer now work in any order.

Fixed

• PBF reader now decodes locations of invisible nodes properly.
• Invalid Delta encode iterator dereference.
• Lots of includes fixed to include (only) what's used.
• Dangling reference in area assembly code.

2.4.1 - 2015-08-29

Fixed

• CRC calculation of tags and changesets.

2.4.0 - 2015-08-29

Added

• Checks that user names, member roles and tag keys and values are not longer than 256 * 4 bytes. That is the maximum length 256 Unicode characters can have in UTF-8 encoding.
• Support for GDAL 2. GDAL 1 still works.

Changed

• Improved CMake build scripts.
• Updated internal version of Protozero to 1.1.0.
• Removed toogr* examples. They are in their own repository now. See https://github.com/osmcode/osm-gis-export.
• Files about to be memory-mapped (for instance index files) are now set to binary mode on Windows so the application doesn't have to do this.

Fixed

• Hanging program when trying to open file with an unknown file format.
• Building problems with old boost versions.
• Initialization errors in PBF writer.
• Bug in byte swap code.
• Output on Windows now always uses binary mode, even when writing to stdout, so OSM xml and opl files always use LF line endings.

2.3.0 - 2015-08-18

Added

• Allow instantiating osmium::geom::GEOSFactory with existing GEOS factory.
• Low-level functions to support generating a architecture- and endian- independant CRC from OSM data. This is intended to be uses with boost::crc.
• Add new debug output format. This format is not intended to be read automatically, but for human consumption. It formats the data nicely.
• Make writing of metadata configurable for XML and OPL output (use add_metadata=false as file option).

Changed

• Changed add_user() and add_role() in builders to use string length without the 0-termination.
• Improved code setting file format from suffix/format argument.
• Memory mapping utility class now supports readonly, private writable or shared writable operation.
• Allow empty version (0) in PBF files.
• Use utf8cpp header-only lib instead of boost for utf8 decoding. The library is included in the libosmium distribution.
• New PBF reader and writer based on the protozero. A complete rewrite of the code for reading and writing OSM PBF files. It doesn't use the Google protobuf library and it doesn't use the OSMPBF/OSM-Binary library any more. Instead is uses the protozero lightweight protobuf header library which is included in the code. Not only does the new code have less dependencies, it is faster and more robust. https://github.com/mapbox/protozero

Fixed

• Various smaller bug fixes.
• Add encoding for relation member roles in OPL format.
• Change character encoding to new format in OPL: variable length hex code between % characters instead of a % followed by 4-digit hex code. This is necessary because unicode characters can be longer than the 4-digit hex code.
• XML writer: The linefeed, carriage return, and tab characters are now escaped properly.
• Reading large XML files could block.

2.2.0 - 2015-07-04

Added

• Conversion functions for some low-level types.
• BoolVector index class.
• min_op/max_op utility functions.
• More tests here and there.
• Helper methods is_between() and is_visible_at() to DiffObject.
• GeoJSON factory using the RapidJSON library.
• Support for tile calculations.
• Create simple polygons from ways in geom factories.
• MemoryMapping and TypedMemoryMapping helper classes.
• close() function to mmap_vector_base class.
• Function on Buffer class to get iterator to specific offset.
• Explicit cast operator from osmium::Timestamp to uint32_t.

Changed

• Throw exception on illegal values in functions parsing strings to get ids, versions, etc.
• Improved error message for geometry exceptions.

Fixed

• Throw exception from dump_as_array() and dump_as_list() functions if not implemented in an index.
• After writing OSM files, program could stall up to a second.
• Dense location store was written out only partially.
• Use uint64_t as counter in benchmarks, so there can be no overflows.
• Example programs now read packed XML files, too.
• Refactoring of memory mapping code. Removes leak on Windows.
• Better check for invalid locations.
• Mark cbegin() and cend() of mmap_vector_base as const functions.

2.1.0 - 2015-03-31

Added

• When writing PBF files, sorting the PBF stringtables is now optional.
• More tests and documentation.

Changed

• Some functions are now declared noexcept.
• XML parser fails now if the top-level element is not osm or osmChange.

Fixed

• Race condition in PBF reader.
• Multipolygon collector was accessing non-existent NodeRef.
• Doxygen documentation wan't showing all classes/functions due to a bug in Doxygen (up to version 1.8.8). This version contains a workaround to fix this.
