- Update to 1.4.6:
* API classes now support C++11 move semantics when using a compiler which
we are confident supports them (currently compilers which define
__cplusplus >= 201103 plus a special check for MSVC 2015 or later).
C++11 move semantics provide a clean and efficient way for threaded code to
hand-off Xapian objects to worker threads, but in this case it's very
unhelpful for availability of these semantics to vary by compiler as it
quietly leads to a build with non-threadsafe behaviour. To address this,
user code can #define XAPIAN_MOVE_SEMANTICS before #include <xapian.h> to
force this on, and will then get a compilation failure if the compiler
lacks suitable support.
* MSet::snippet():
+ We were only escaping output for HTML/XML in some cases, which would
potentially allow HTML to be injected into output (this fixes
bnc#1099925, CVE-2018-0499).
+ Include certain leading non-word characters in snippets. Previously we
started the snippet at the start of the first actual word, but there are
various cases where including non-word characters in front of the actual
word adds useful context or otherwise aids comprehension.
* Add MSetIterator::get_sort_key() method. The sort key has always been
available internally, but wasn't exposed via the public API before, which
seems like an oversight as the collapse key has long been available.
* Database::compact():
+ Allow Compactor::resolve_duplicate_metadata() implementations to delete
entries. Previously if an implementation returned an empty string this
would result in a user meta-data entry with an empty value, which isn't
normally achievable (empty meta-data values aren't stored), and so will
cause odd behaviour. We now handle an empty returned value by
interpreting it in the natural way - it means that the merged result is
to not set a value for that key in the output database.
