Portability:
* Support macOS 11.0 - AC_CANONICAL_HOST identifies this as darwin20, which
wasn't caught by our glob pattern. Patch from FX Coudert in
https://github.com/xapian/xapian/pull/319
CSharp:
* Wrap const std::string* parameters to accept a string or null in C#. See #204.
Java:
* Wrap const std::string* parameters to accept a String or null in Java.
Perl:
* Fix minor documentation typo.
API:
* MSet::snippet(): The snippet now includes trailing punctuation which carries
meaning or gives useful context. See
https://github.com/xapian/xapian/pull/180, reported by Robert Stepanek.
* MSet::snippet(): Fix segfault generating snippet from default-constructed
MSet. This probably isn't something you'd typically do, but it shouldn't
crash. Found during extended testing of #803 (which only affected git
master) which was reported by Robert Stepanek.
* Remove trailing full stop from exception messages. We conventionally don't
include one, but a few cases didn't follow that convention.
testsuite:
* Replace direct use of ftime() which gives deprecation warnings with recent
mingw. Reported by srinivasyadav22.
matcher:
* Fix segfault in rare cases in the query optimiser. We keep a pointer to the
most recent posting list to use as a hint for opening the next posting list,
but the existing mechanism to take ownership of this hint had a flaw. We now
invalidate the hint in situations where it might be indirectly deleted which
is safe, but somewhat conservative.
* Improve the optimisation of an always-matching OP_VALUE_GE to also take
effect when the value slot's lower bound is equal to the limit of the
OP_VALUE_GE. Patch from boda sadalla.
glass backend:
* Report the correct errno value if commit() fails. We were potentially
reporting ENOENT from an unlink() call cleaning up a temporary file prior to
throwing the exception instead.
documentation:
* Fix missing menus in API documentation. Newer doxygen generates .js files
which we also need to distribute and install. Reported by sec^nd on #xapian.
* Note OP_FILTER ignored subquery bug fixed in 1.4.15 as present in 1.4.14 and
older.
portability:
* Use our own autoconf cache variable namespace (xo_cv_ prefix instead of
ac_cv_) to avoid colliding with standard autoconf macro use if config.site or
a shared config.cache is used. The former case caused a build failure for
the OpenBSD port with 1.4.15, reported by Lucas R.
* Use clock_gettime() and nanosleep() under modern mingw as these allow higher
precision than what we previously used.
Bindings:
* Remove code to support SVN snapshots since we stopped using SVN more than 5
years ago.
* Ignore overloads for logical ops, *, /. These were already ignored for
several languages, and aren't actually usefully wrapped for any of the other
languages.
CSharp:
* Work around mono terminfo parsing bug in more cases. With this, "make",
"make check", "make install" and "make uninstall" all work on Ubuntu 18.10.
Patch from Dipanshu Garg, fixes https://github.com/xapian/xapian/pull/287 and
#801.
Lua:
* Allow passing a Lua function as a MatchSpy. This was supposed to be
supported already, but the typemaps weren't set up.
* On platforms where sizeof(long) is 4, SWIG was wrapping Xapian::BAD_VALUENO
as a negative constant in Lua, which was then rejected by a check which
disallows passing negative values for unsigned C++ types. We now direct SWIG
to handle Xapian::valueno as double (which is what numbers in Lua usually
actually are) which gives us an unsigned constant, and also eliminates the
negative value check.
* Correct documentation - get_description() is wrapped as tostring() in Lua,
not str() as we previously claimed.
* Add test coverage for passing Lua function for a Stopper.
Perl:
* Resolve the remaining issues and remove the "experimental" marker:
+ Add search_xapian_compat() function which sets up aliases in the
Search::Xapian namespace to aid writing code which uses either
Search::Xapian or this module.
+ Allow passing Perl sub for simpler Xapian functor classes. This fills in a
missing feature compared to Search::Xapian. See #523.
+ Remove useless PerlStopper class which was an incomplete copy of the
apparently non-functional Search::Xapian::PerlStopper. We now support
passing a Perl sub for a Stopper object.
+ Adjust some method names to match Search::Xapian. Iterators now support
inc() (and dec() where the C++ class supports operator--) like
Search::Xapian, rather than increment() and prev(). Reported by Eric Wong
in #523.
+ Drop undocumented and unexpected extra equals() method.
+ Provide compatibility with ENQ_ASCENDING, etc constants. SWIG wraps these
as $Xapian::Enquire::ASCENDING, which better matches the C++ API, but
Search::Xapian wraps this as Search::Xapian::ENQ_ASCENDING, etc so provide
those too for compatibility. Reported by Eric Wong in #523.
+ Drop stringification and int conversion overloads. These seem more
confusing than helpful, and overloading stringification works badly
with SWIG-generated bindings.
+ Document remaining known differences from Search::Xapian.
* Update recently tested versions in README.
* Improve documentation.
* Fix t/02pod.t to look for files in right directory.
Ruby:
* Don't print iterator sizes to stdout. This was some debugging accidentally
left in as part of a change in 1.4.12. Patch from Dan Callaghan.
API:
* Database::check(): Fix bogus error reports for documents with length zero
due to a new check added in 1.4.6 that the doclength was between the stored
upper and lower bounds, which failed to allow for the lower bound ignoring
documents with length zero (since documents indexed only by boolean terms
aren't involved in weighted searches). Reported by David Bremner.
* Query: Use of Query::MatchAll in multithreaded code causes problems because
the reference counting gets messed up by concurrent updates. Document that
Query(string()) should be used instead of MatchAll in multithreaded code, and
avoid using it in library code. Reported by Germán M. Bravo.
* Stem:
+ Stemming algorithms added for Irish, Lithuanian, Nepali and Tamil.
+ Merge Snowball compiler changes which improve code generation.
+ Merge optimisations to the Arabic and Turkish stemmers.
glass backend:
* A long-lived cursor on a table in a WritableDatabase could get into
an invalid state, which typically resulted in a DatabaseCorruptError
being thrown with the message:
Db block overwritten - are there multiple writers?
But in fact the on-disk database is not corrupted - it's just that
the cursor in memory has got into an inconsistent state. It looks
like we'll always detect the inconsistency before it can cause on-disk
corruption but it's hard to be completely certain.
The bug is in code to rebuild the cursor when the underlying table
changes in ways which require that, which is a fairly rare occurrence
to start with, and only triggers when a block in the cursor has been
released, reallocated, and we tried to load it in the cursor at the
same level - the cursor wrongly assumes it has the current version
of the block.
Reported with a reproducer by Sylvain Taverne. Confirmed by David
Bremner as also fixing a problem in notmuch for which he hadn't managed
to find a reduced reproducer.
