xapian-core

• QueryParser: Fix handling of CJK query over multiple prefixes. Previously all the n-gram terms were AND-ed together - now we AND together for each prefix, then OR the results. Fixes #719, reported by Aaron Li.

• Fix incorrect results due to uninitialised memory. The array holding max weight values in MultiAndPostList is never initialised if the operator is unweighted, but the values are still used to calculate the max weight to pass to subqueries, leading to incorrect results. This can be observed with an OR under an unweighted AND (e.g. OR under AND on the right side of AND_NOT). The fix applied is to simply default initialise this array, which should lead to a max weight of 0.0 being passed on to subqueries. Bug reported in notmuch by Kirill A. Shutemov, and forwarded by David Bremner.

• Various portability fixes.

Java bindings

• Disable parallel make for java subdirectory as it causes random build failures. Reported by Lucas Nussbaum in ​https://bugs.debian.org/848733

Search::Xapian Perl bindings

• Wrap WritableDatabase::commit(), which is the preferred name for WritableDatabase::flush().

• Avoid perl -W in tests as that seems to break recent versions of Test::More.

• Suppress dummy warning using undef value when building against xapian-core 1.4.x.
