testsuite:
* Expand canceltransaction1 to test value changes are rolled back.
matcher:
* Minor optimisations to DPHWeight and TfIdfWeight weighting formulae
calculations.
* Optimise LatLongDistancePostingSource to avoid pow() call on each document
with default k2 setting.
glass backend:
* Fix bug in recovery from WritableDatabase::commit() failing.
If renaming to switch the new version file live fails (e.g. due to the disk
being full) we discard the changes, try to write and switch to a different
new version file with an increased revision (on failure of this too we close
the database), then throw DatabaseError.
Unfortunately the roll-back of state is not complete, and if we successfully
switch to the different new version file then that bad state persists on
disk.
In order for this bug to manifest, repeating essentially the same operation
which just failed needs to succeed which seems more likely to be a happen
when using a filing system which has more sophisticated freespace handling
(the reporter was using btrfs), though it's possible with any FS if another
process frees up disk space in the small window between the two operations.
Thanks to Uwe Kleine-Koenig for reporting and especially for coming up with an
easy way to reproduce.
build system:
* configure: Enable -fno-math-errno if supported. We don't make use of maths
function setting errno and if we tell the compiler that it can optimise them
better in some cases.
documentation:
* INSTALL: Document assumptions about platform features
* INSTALL: Add section on clang version requirements.
Bindings:
Lua:
* When passing a Lua function for a Xapian functor object, the wrapper
object was leaked in most cases (except for Xapian::StemImplementation).
Perl:
* Fix testsuite and docs for Perl 5.36.0 change.
Prior to Perl 5.36.0 retrieving the string value of an integer could set
the flag read by "SvPOK()", but that's no longer the case in Perl 5.36.0
and later.
We already document the need to explicitly stringify numeric values
passed where a string is needed, so just add the missing stringification
to the testcase and document that it's required in more places when using
Perl 5.36.0 and later.
PHP8:
* Add support for PHP8 (PHP 8.0, 8.1 and 8.2 should all work).
The PHP bindings are now implemented entirely in C++ code using PHP's
C extension API, and the `xapian.php` wrapper file no longer exists.
This change means smaller and faster bindings. See the documentation for a
recommended way to write code which works with both PHP7 and PHP8 bindings.
To add PHP8 support we've had to drop support for PHP7. PHP7.4 reached end
of life on 2022-11-28 so hopefully this isn't a problem for too many people,
but if you need support for PHP7 please use xapian-bindings <= 1.4.21.
Fixes#817, reported by Ryan Schmidt.
* We now set the version in the metadata of the PHP module to the
xapian-bindings version (previously it was unversioned).
Python:
* Drop support for Python 2.6. We need to use SWIG 4.1.0 for PHP8 support, but
that no longer supports Python 2.6 so we have to raise the minimum Python 2
version to Python 2.7.
The last Python 2.6 release was in 2013 so hopefully this isn't a problem for
anyone, but if you still need to use Python 2.6 please use xapian-bindings <=
1.4.21.
Python3:
* Drop support for Python 3.2. We need to use SWIG 4.1.0 for PHP8 support, but
that no longer supports Python 3.2 so we have to raise the minimum Python 3
version to Python 3.3.
The last Python 3.2 release was in 2014 so hopefully this isn't a problem for
anyone, but if you still need to use Python 3.2 please use xapian-bindings <=
1.4.21.
Ruby:
* Fix new Ruby 3.2 warning "undefining the allocator of T_DATA class
swig_runtime_data" (fixed by the change to using a newer SWIG version).
