osmcode/libosmium v2.14.1

Version 2.14.1

on GitHub

Changed

• Libosmium now needs the newest Protozero version 1.6.3.
• Removes dependency on the utfcpp library for conversions between Unicode code points and UTF-8. We have our own functions for this now. This also gives us more control on where errors are thrown in this code.
• Add support for using the CRC32 implementation from the zlib library in addition to the one from Boost. It is significantly faster and means we have one less dependency, because zlib is needed anyway in almost all programs using Osmium due to its use in the PBF format. Set macro OSMIUM_TEST_CRC_USE_BOOST before compiling the tests, if you want to run the tests with the boost library code, otherwise it will use the zlib code. Note that to use this you have to change your software slightly, see the documentation of the CRC_zlib class for details.
• Add a clear_user() function to OSMObject and Changeset which allows removing the user name of an entity without re-creating it in a new buffer.
• In Osmium the 0 value of the Timestamp is used to denote the "invalid" Timestamp, and its output using the to_iso() function is the empty string. But this is the wrong output for OSM XML files, where a timestamp that's not set should still be output as 1970-01-01T00:00:00Z. This version introduces a new to_is_all() function which will do this and uses that function in the XML writer.
• Use protozero::byteswap_inplace instead of htonl/ntohl. Makes the code simpler and also works on Windows.
• Marked MultipolygonCollector class as deprecated. Use the MultipolygonManager class introduced in 2.13.0 instead.
• Lots of code cleanups especially around asserts. Libosmium checks out clean with clang-tidy now. Some documentation updates.

Fixed

• Fix compilation error when fileno() is a macro (as in OpenBSD 6.3).
• Make Box output consistent with the output of a single Location and avoids problems with some locales.
