# Change Log
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).
## [unreleased] -
### Added
### Changed
### Fixed
## [2.13.1] - 2017-08-25
### Added
- New "blackhole" file format which throws away all data written into it.
Used for benchmarking.
### Changed
- When reading OPL files, CRLF file endings are now handled correctly.
- Reduce the max number of threads allowed for the `Pool` to 32. This should
still be plenty and might help with test failures on some architectures.
### Fixed
- Tests now run correctly independent of git `core.autocrlf` setting.
- Set binary mode for all files on Windows in example code.
- Low-level file functions now set an invalid parameter handler on Windows
to properly handle errors.
- Restore earlier behaviour allowing zero-length mmap. It is important to
allow zero-length memory mapping, because it is possible that such an index
is empty, for instance when one type of object is missing from an input
file as in https://github.com/osmcode/osmium-tool/issues/65. Drawback is
that files must be opened read-write for this to work, even if we only
want to read from them.
- Use Approx() to compare floating point values in tests.
- Fix broken `Item` test on 32 bit platforms.
## [2.13.0] - 2017-08-15
### Added
- New `RelationsManager` class superseeds the `relations::Collector` class.
The new class is much more modular and easier to extend. If you are using
the Collector class, you are encouraged to switch.
- New `MultipolygonManager` based on the `RelationsManager` class superseeds
the `MultipolygonCollector` class. The examples have been changed to use the
new class and all users are encouraged to switch. There is also a
`MultipolygonManagerLegacy` class if you still need old-style multipolygon
support (see below).
- New `FlexMem` index class that works with input files of any size and
stores the index in memory. This should now be used as the default index
for node location stores. Several example programs now use this index.
- New `CallbackBuffer` class, basically a convenient wrapper around the
`Buffer` class with an additional callback function that is called whenever
the buffer is full.
- Introduce new `ItemStash` class for storing OSM objects in memory.
- New `osmium::geom::overlaps()` function to check if two `Box` objects
overlap.
- Add function `IdSet::used_memory()` to get estimate of memory used in the
set.
- New `is_defined()` and `is_undefined()` methods on `Location` class.
- Tests for all provided example programs. (Some tests currently fail
on Windows for the `osmium_index_lookup` program.)
### Changed
- The area `Assembler` now doesn't work with old-style multipolygons (those
are multipolygon relations with the tags on the outer ways(s) instead of
on the relation) any more. Because old-style multipolygons are now (mostly)
gone from the OSM database this is usually what you want. The new
`AssemblerLegacy` class can be used if you actually need support for
old-style multipolygons, for instance if you are working with historical
data. (In that case you also need to use the `MultipolygonManagerLegacy`
class instead of the `MultipolygonManager` class.)
- Changes for consistent ordering of OSM data: OSM data can come in any order,
but usual OSM files are ordered by type, ID, and version. These changes
extend this ordering to negative IDs which are sometimes used for objects
that have not been uploaded to the OSM server yet. The negative IDs are
ordered now before the positive ones, both in order of their absolute value.
This is the same ordering as JOSM uses.
- Multipolygon assembler now checks for three or more overlapping segments
which are always an error and can report them.
- Enable use of user-provided `thread::Pool` instances in `Reader` and
`Writer` for special use cases.
- Growing a `Buffer` will now work with any capacity parameter, it is
always rounded up for proper alignment. Buffer constructor with three
arguments will now check that commmitted is not larger than capacity.
- Updated embedded protozero to 1.5.2.
- Update version of Catch unit test framework to 1.9.7.
- And, as always, lots of small code cleanups and more tests.
### Fixed
- Buffers larger than 2^32 bytes do now work.
- Output coordinate with value of -2^31 correctly.
- Changeset comments with more than 2^16 characters are now allowed. The new
maximum size is 2^32.
- `ChangesetDiscussionBuilder::add_comment_text()` could fail silently instead
of throwing an exception.
- Changeset bounding boxes are now always output to OSM files (any format)
if at least one of the corners is defined. This is needed to handle broken
data from the main OSM database which contains such cases. The OPL reader
has also been fixed to handle this case.
- In the example `osmium_location_cache_create`, the index file written is
always truncated first.
## [2.12.2] - 2017-05-03
### Added
- Add two argument (key, value) overload of `TagMatcher::operator()`.
### Changed
- Detect, report, and remove duplicate ways in multipolygon relations.
- Change EOF behaviour of Reader: The `Reader::read()` function will now
always return an invalid buffer exactly once to signal EOF.
- Update QGIS multipolygon project that is part of the test suite to show
more problem types.
- Copy multipolygon QGIS file for tests to build dir in cmake step.
- Some code cleanups and improved debug output in multipolygon code.
- Refactor I/O code to simplify code.
- Disable some warnings on MSVC.
- Various small code and build script changes.
### Fixed
- Two bugs in area assembler affecting very complex multipolygons and
multipolygons with overlapping or nearly overlapping lines.
- Invalid use of iterators leading to undefined behaviour in area assembler
code.
- Area assembler stats were not correctly counting inner rings that are
areas in their own right.
- Fix a thread problem valgrind found that might or might not be real.
- Read OPL file correctly even if trailing newline in file is missing.
- Include order for `osmium/index/map` headers and
`osmium/index/node_locations_map.hpp` (or
`osmium/handler/node_locations_for_ways.hpp`) doesn't matter any more.
## [2.12.1] - 2017-04-10
### Added
- New `TagsFilter::set_default_result()` function.
### Changed
- Use larger capacity for `Buffer` if necessary for alignment instead of
throwing an exception. Minimum buffer size is now 64 bytes.
- Check order of input data in relations collector. The relations collector
can not deal with history data or a changes file. This was documented as a
requirement, but often lead to problems, because this was ignored by users.
So it now checks that the input data it gets is ordered and throws an
exception otherwise.
- When writing an OSM file, set generator to libosmium if not set by app.
### Fixed
- Infinite loop in `Buffer::reserve_space()`. (Issue #202.)
- `ObjectPointerCollection::unique()` now removes elements at end.
- Tests comparing double using `==` operator.
- Build on Cygwin.
## [2.12.0] - 2017-03-07
### Added
- `TagMatcher` and `TagsFilter` classes for more flexibly matching tags and
selecting objects based on tags. This obsoletes the less flexible classes
based on `osmium::tags::Filter` classes.
- Extended `index::RelationsMap(Stash|Index)` classes to also allow
parent-to-member lookups.
- New `nrw_array` helper class.
- `ObjectPointerCollection::unique()` function.
### Changed
- Area assembler can now detect invalid locations and report them in the
stats and through the problem reporter. If the new config option
`ignore_invalid_locations` is set, the Assembler will pretend they weren't
even referenced in the ways. (Issue #195.)
- `osmium::area::Assembler::operator()` will now return a boolean reporting
whether building of the area(s) was successful.
- Split up area `Assembler` class into three classes: The
`detail::BasicAssembler` is now the parent class. `Assembler` is the child
class for usual use. The new `GeomAssembler` also derives from
`BasicAssembler` and builds areas without taking tags into account at all.
This is to support osm2pgsql which does tag handling itself. (Issue #194.)
- The `Projection` class can do any projection supported by the Proj.4
library. As a special case it now uses our own Mercator projection
functions when the web mercator projection (EPSG 3857) is used. This is
much faster than going through Proj.4.
- Better error messages for low-level file utility functions.
- Mark `build_tag_list*` functions in `builder_helper.hpp` as deprecated. You
should use the functions from `osmium/builder/attr.hpp` instead.
- Improved performance of the `osmium::tags::match_(any|all|none)_of`
functions.
- Improved performance of string comparison in `tags::Filter`.
- Update version of Catch unit test framework to 1.8.1. This meant some
tests had to be updated.
- Use `get_noexcept()` in `NodeLocationsForWays` handler.
- And lots of code and test cleanups...
### Fixed
- Terminate called on full non-auto-growing buffer. (Issue #189.)
- When file formats were used that were not compiled into the binary, it
terminated instead of throwing. (Issue #197.)
- Windows build problem related to including two different winsock versions.
- Windows build problem related to forced build for old Windows versions.
(Issue #196.)
- Clear stream contents in ProblemReporterException correctly.
- Add `-pthread` compiler and linker options on Linux/OSX. This should fix
a problem where some linker versions will not link binaries correctly when
the `--as-needed` option is used.
- The `Filter::count()` method didn't compile at all.
- XML reader doesn't fail on relation member ref=0 any more.
## [2.11.0] - 2017-01-14
### Added
- New index::RelationsMap(Stash|Index) classes implementing an index for
looking up parent relation IDs given a member relation ID.
- Add `get_noexcept()` method to all index maps. For cases where ids are
often not in the index using this can speed up a program considerably.
- New non-const WayNodeList::operator[].
- Default constructed "invalid" Coordinates.
- Tile constructor from web mercator coordinates and some helper
functions for tile arithmetic.
- Tag matcher matching keys using a regex.
- New `envelope()` functions on `NodeRefList`, `Way`, and `Area` returning a
`Box` object with the geometric envelope of the object.
- Add `amenity_list` example.
### Changed
- Replaced the implementation for the web mercator projection using the usual
tan-formula with a polynomial approximation which is much faster and good
enough for OSM data which only has ~1cm resolution anyway. See
https://github.com/osmcode/mercator-projection for all the details and
benchmarks. You can disable this by defining the macro
`OSMIUM_USE_SLOW_MERCATOR_PROJECTION` before including any of the Osmium
headers.
- Removed the outdated `Makefile`. Always use CMake directly to build.
- Refactoring of `osmium::apply()` removing the resursive templates for faster
compile times and allowing rvalue handlers.
- Lots of code and test cleanups and more documentation.
### Fixed
- Handle endianess on FreeBSD properly.
- Fixed doxygen config for reproducible builds.
## [2.10.3] - 2016-11-20
### Changed
- Round out ObjectPointerCollection implementation and test it.
- Updated embedded protozero to 1.4.5.
## [2.10.2] - 2016-11-16
### Changed
- Updated embedded protozero to 1.4.4.
### Fixed
- Buffer overflow in osmium::Buffer.
## [2.10.1] - 2016-11-15
### Changed
- Updated embedded protozero to 1.4.3.
### Fixed
- Made IdSet work on 32bit systems.
- Fixed endianness check for WKB tests.
## [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.

# Notes for Developers
Read this if you want to contribute to Libosmium.
## Namespace
All Osmium code MUST be in the `osmium` namespace or one of its sub-namespaces.
## Include-Only
Osmium is a include-only library. You can't compile the library itself. There
is no `libosmium.so` or `libosmium.dll`.
One drawback ist that you can't have static data in classes, because there
is no place to put this data.
All free functions must be declared `inline`.
## Coding Conventions
These coding conventions have been changing over time and some code is still
different.
* All include files have `#ifdef` guards around them, macros are the path name
in all uppercase where the slashes (`/`) have been changed to underscore (`_`).
* Class names begin with uppercase chars and use CamelCase. Smaller helper
classes are usually defined as struct and have lowercase names.
* Macros (and only macros) are all uppercase. Use macros sparingly, usually
a simple (maybe constexpr) inline function is better. Undef macros after use
if possible.
* Macros should only be used for controlling which parts of the code should be
included when compiling or to avoid major code repetitions.
* Variables, attributes, and function names are lowercase with
`underscores_between_words`.
* Class attribute names start with `m_` (member).
* Use `descriptive_variable_names`, exceptions are well-established conventions
like `i` for a loop variable. Iterators are usually called `it`.
* Declare variables where they are first used (C++ style), not at the beginning
of a function (old C style).
* Names from external namespaces (even `std`) are always mentioned explicitly.
Do not use `using` (except for `std::swap`). This way we can't even by
accident pollute the namespace of the code using Osmium.
* Always use the standard swap idiom: `using std::swap; swap(foo, bar);`.
* `#include` directives appear in three "blocks" after the copyright notice.
The blocks are separated by blank lines. First block contains `#include`s for
standard C/C++ includes, second block for any external libs used, third
block for osmium internal includes. Within each block `#include`s are usually
sorted by path name. All `#include`s use `<>` syntax not `""`.
* Names not to be used from outside the library should be in a namespace
called `detail` under the namespace where they would otherwise appear. If
whole include files are never meant to be included from outside they should
be in a subdirectory called `detail`.
* All files have suffix `.hpp`.
* Closing } of all classes and namespaces should have a trailing comment
with the name of the class/namespace.
* All constructors with one (or more arguments if they have a default) should
be declared "explicit" unless there is a reason for them not to be. Document
that reason.
* If a class has any of the special methods (copy/move constructor/assigment,
destructor) it should have all of them, possibly marking them as default or
deleted.
* Typedefs have `names_like_this_type` which end in `_type`. Typedefs should
use the new `using foo_type = bar` syntax instead of the old
`typedef bar foo_type`.
* Template parameters are single uppercase letters or start with uppercase `T`
and use CamelCase.
* Always use `typename` in templates, not `class`: `template <typename T>`.
* The ellipsis in a variadic template never has a space to the left of it and
always has a space to the right: `template <typename... TArgs>` etc.
Keep to the indentation and other styles used in the code.
## C++11
Osmium uses C++11 and you can use its features such as auto, lambdas,
threading, etc. There are a few features we do not use, because even modern
compilers don't support them yet. This list might change as we get more data
about which compilers support which feature and what operating system versions
or distributions have which versions of these compilers installed.
Use `include/osmium/util/compatibility.hpp` if there are compatibility problems
between compilers due to different C++11 support.
## Operating systems
Usually all code must work on Linux, OSX, and Windows. Execptions are allowed
for some minor functionality, but please discuss this first.
When writing code and tests, care must be taken that everything works with the
CR line ending convention used on Linux and OSX and the CRLF line ending used
on Windows. Note that `git` can be run with different settings regarding line
ending rewritings on different machines making things more difficult. Some
files have been "forced" to LF line endings using `.gitattributes` files.
## 32bit systems
Libosmium tries to work on 32bit systems whereever possible. But there are
some parts which will not work on 32bit systems, mainly because the amount
of main memory available is not enough for it to work anyway.
## Checking your code
The Osmium makefiles use pretty draconian warning options for the compiler.
This is good. Code MUST never produce any warnings, even with those settings.
If absolutely necessary pragmas can be used to disable certain warnings in
specific areas of the code.
If the static code checker `cppcheck` is installed, the CMake configuration
will add a new build target `cppcheck` that will check all `.cpp` and `.hpp`
files. Cppcheck finds some bugs that gcc/clang doesn't. But take the result
with a grain of salt, it also sometimes produces wrong warnings.
Set `BUILD_HEADERS=ON` in the CMake config to enable compiling all include
files on their own to check whether dependencies are all okay. All include
files MUST include all other include files they depend on.
Call `cmake/iwyu.sh` to check for proper includes and forward declarations.
This uses the clang-based `include-what-you-use` program. Note that it does
produce some false reports and crashes often. The `osmium.imp` file can be
used to define mappings for iwyu. See the IWYU tool at
<http://code.google.com/p/include-what-you-use/>.
## Testing
There are unit tests using the Catch Unit Test Framework in the `test`
directory, some data tests in `test/osm-testdata` and tests of the examples in
`test/examples`. They are built by the default cmake config. Run `ctest` to
run them. We can always use more tests.
Tests are run automatically using the Travis (Linux/Mac) and Appveyor (Windows)
services. We automatically create coverage reports on Codevoc.io. Note that
the coverage percentages reported are not always accurate, because code that
is not used in tests at all will not necessarily end up in the binary and
the code coverage tool will not know it is there.

[![Coverage Status](https://codecov.io/gh/osmcode/libosmium/branch/master/graph/badge.svg)](https://codecov.io/gh/osmcode/libosmium)
## Documenting the code
All namespaces, classes, functions, attributes, etc. should be documented.
Osmium uses the [Doxygen](http://www.doxygen.org) source code documentation
system. If it is installed, the CMake configuration will add a new build
target, so you can build it with `make doc`.

# Libosmium
http://osmcode.org/libosmium
A fast and flexible C++ library for working with OpenStreetMap data.
Libosmium works on Linux, Mac OSX and Windows.
[![Travis Build Status](https://secure.travis-ci.org/osmcode/libosmium.svg)](https://travis-ci.org/osmcode/libosmium)
[![Appveyor Build Status](https://ci.appveyor.com/api/projects/status/github/osmcode/libosmium?svg=true)](https://ci.appveyor.com/project/Mapbox/libosmium)
[![Coverage Status](https://codecov.io/gh/osmcode/libosmium/branch/master/graph/badge.svg)](https://codecov.io/gh/osmcode/libosmium)
Please see the [Libosmium manual](http://osmcode.org/libosmium/manual.html)
for more details than this README can provide.
## Prerequisites
Because Libosmium uses many C++11 features you need a modern compiler and
standard C++ library. Osmium needs at least GCC 4.8 or clang (LLVM) 3.4.
(Some parts may work with older versions.)
Different parts of Libosmium (and the applications built on top of it) need
different libraries. You DO NOT NEED to install all of them, just install those
you need for your programs.
For details see the [list of
dependencies](http://osmcode.org/libosmium/manual.html#dependencies) in the
manual.
The following external (header-only) libraries are included in the libosmium
repository:
* [gdalcpp](https://github.com/joto/gdalcpp)
* [protozero](https://github.com/mapbox/protozero)
* [utfcpp](http://utfcpp.sourceforge.net/)
## Directories
* benchmarks: Some benchmarks checking different parts of Libosmium.
* cmake: CMake configuration scripts.
* doc: Config for API reference documentation.
* examples: Osmium example applications.
* include: C/C++ include files. All of Libosmium is in those header files
which are needed for building Osmium applications.
* test: Tests (see below).
## Building
Osmium is a header-only library, so there is nothing to build for the
library itself.
But there are some tests and examples that can be build. Libosmium uses
cmake:
mkdir build
cd build
cmake ..
make
This will build the examples and tests. Call `ctest` to run the tests.
For more detals see the
[Building Libosmium](http://osmcode.org/libosmium/manual.html#building-libosmium)
chapter in the manual.
## Testing
See the
[Libosmium Manual](http://osmcode.org/libosmium/manual.html#running-tests)
for instructions.
## Switching from the old Osmium
If you have been using the old version of Osmium at
https://github.com/joto/osmium you might want to read about the [changes
needed](http://osmcode.org/libosmium/manual.html#changes-from-old-versions-of-osmium).
## License
Libosmium is available under the Boost Software License. See LICENSE.txt.

Libosmium was mainly written and is maintained by Jochen Topf
(jochen@topf.org). See the git commit log for other authors.

# Benchmarks
Benchmarks check the performance of different parts of Libosmium.
## Preparations
To run the benchmarks first make a directory for the data files somewhere
(outside the repository) and set the `DATA_DIR` environment variable:
export DATA_DIR=benchmark_data
mkdir $DATA_DIR
Then copy the OSM files you want to do the benchmarks with into this directory.
You can use the `download_data.sh` script to download a selection of OSM files
in different sizes, but you can use a different selection, too. The benchmarks
will use whatever files you have in the `DATA_DIR` directory.
The download script will start the data files names with a number in order of
the size of the file from smallest to largest. You can use the same convention
or use a different one. Benchmarks will be run on the files in alphabetical
order.
The files don't have to be in that directory, you can add soft links from that
directory to the real file locations if that suits you.
## Compiling the benchmarks
To build the benchmarks set the `BUILD_BENCHMARKS` option when configuring with
CMake and run the compilation by calling `make` (or whatever build tool you
are using).
## Running the benchmarks
Go to the build directory and run `benchmarks/run_benchmarks.sh`. You can also
run each benchmark on its own by calling the respective script in the
`benchmarks` directory.
Results of the benchmarks will be printed to stdout, you might want to redirect
them into a file.

/*
This benchmarks compares the run time for statically vs. dynamically
configured index maps. You can configure index maps at compile-time using
typedefs or at run-time using polymorphism.
This will read the input file into a buffer and then run the
NodeLocationForWays handler multiple times over the complete data. The
number of runs depends on the size of the input, but is never smaller
than 10.
Do not run this with very large input files! It will need about 10 times
as much RAM as the file size of the input file.

# Author thomas.roehr@dfki.de
#
# Version 0.3 2013-07-02
# - rely on `gem content` to find library and header
# - introduce GEM_OS_PKG to allow search via pkgconfig
# Version 0.2 2010-01-14
# - add support for searching for multiple gems
# Version 0.1 2010-12-15
# - support basic search functionality
# - tested to find rice
#
# OUTPUT:
#
# GEM_INCLUDE_DIRS After successful search contains the include directores
#
# GEM_LIBRARIES After successful search contains the full path of each found library
#
#
# Usage:
# set(GEM_DEBUG TRUE)
# find_package(Gem COMPONENTS rice hoe)
# include_directories(${GEM_INCLUDE_DIRS})
# target_link_libraries(${GEM_LIBRARIES}
#
# in case pkg-config should be used to search for the os pkg, set GEM_OS_PKG, i.e.
# set(GEM_OS_PKG TRUE)
#
# Check for how 'gem' should be called

#
# Find the Libosmium headers and, optionally, several components needed
# for different Libosmium functions.
#
#----------------------------------------------------------------------
#
# Usage:
#
# Copy this file somewhere into your project directory, where cmake can
# find it. Usually this will be a directory called "cmake" which you can
# add to the CMake module search path with the following line in your
# CMakeLists.txt:
#
# list(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
#
# Then add the following in your CMakeLists.txt:
#
# find_package(Osmium [version] REQUIRED COMPONENTS <XXX>)
# include_directories(SYSTEM ${OSMIUM_INCLUDE_DIRS})
#
# The version number is optional. If it is not set, any version of
# libosmium will do.
#
# For the <XXX> substitute a space separated list of one or more of the
# following components:
#
# pbf - include libraries needed for PBF input and output
# xml - include libraries needed for XML input and output
# io - include libraries needed for any type of input/output
# geos - include if you want to use any of the GEOS functions
# gdal - include if you want to use any of the OGR functions
# proj - include if you want to use any of the Proj.4 functions
# sparsehash - include if you use the sparsehash index
#
# You can check for success with something like this:
#
# if(NOT OSMIUM_FOUND)

Osmium is a fast and flexible C++ library for working with OpenStreetMap
data.
This is the API documentation that was automatically created from the
source code. For more information about the Osmium Library see
http://osmcode.org/libosmium .
Osmium is free software and available under the Boost Software License.
The source code is available at https://github.com/osmcode/libosmium .
Osmium is a header-only library. You do not need to compile and link it,
just include the headers you need.
Everything in namespaces called "detail" is for internal Osmium use only,
do not depend on it in your code. Do not include any include files in
directories named "detail" directly. Include files in directories called
"experimental" and everything in namespaces called "experimental" is
unsupported and may change at any time regardless of the status of the rest
of the library.

# Osmium example programs
The programs in this directory are intended as examples for developers. They
contain extensive comments explaining what's going on. Note that the examples
only cover a small part of what Osmium can do, you should also read the manuals
and API documentation.
All programs can be run without arguments and they will tell you how to use
them.
## Very simple examples
* `osmium_read`
* `osmium_count`
* `osmium_debug`
* `osmium_tiles`
## Still reasonably simple examples
* `osmium_amenity_list`
* `osmium_read_with_progress`
* `osmium_filter_discussions`
* `osmium_convert`
* `osmium_pub_names`
* `osmium_road_length`
## More advanced examples
* `osmium_area_test`
* `osmium_create_pois`
## Even more advanced examples
* `osmium_change_tags`
* `osmium_location_cache_create`
* `osmium_location_cache_use`
* `osmium_dump_internal`
* `osmium_index_lookup`
