documentation:
* configure: Add missing AC_ARG_VAR for all programs so that they are
documented in --help output, and so that autoconf knows they are "precious"
and preserves them if configure is rerun even when they're specified via an
environment variable.
* Add usage examples for $jsonobject.
* Fix path to omega in quickstart document. Fixes#813, reported by Jim Lynch.
* Update for the IRC channel move from freenode to libera.chat.
indexers:
* Fix handling of UTF-16 BOMs in XML and HTML - we had the sense of the
endianness indicated by the BOM the wrong way round.
* Avoid making an extra temporary copy of HTML/XML data which has a UTF16 BOM.
* We now ignore an end of line immediately after a PHP close tag to match what
PHP does.
* omindex:
+ Fix handling of formatted xlsx dates in certain cases.
* scriptindex:
+ Add new scriptindex whitespace removal actions `ltrim`, `rtrim`, `squash`,
and `trim`.
+ Improve `truncate` action - if a word ends exactly on the requested length
we now leave it in place rather than removing it.
+ Report the location of previous `unique` action in the error given when
`unique` is used more than once.
omega:
* Clamp START and END with packed timestamps. The 4-byte unsigned packed
time_t format can't represent dates before 1970 or after Sun 07 Feb 2106
06:28:15 UTC so clamp dates before or after these - previously they would
wrap around.
* The JSON produced by $jsonobject no longer contains newlines, which makes it
usable as a single line serialisation format without post-processing.
* Add $base64 OmegaScript command.
* omega: Add flag_no_positions to wrap new
Xapian::QueryParser::FLAG_NO_POSITIONS.
templates:
* Fix topterms template to not trigger early matching. We were checking $msize
before including the `query` template, but doing so would trigger the query
to be run, which means that settings early in the `query` template which
should affect the result (such as $setmap{prefix,...}) were being ignored
when the `topterms` template was used. Partly addresses #815, reported by
Gennadiy.
* Add field support to opensearch and xml templates. These templates now also
search title, topic and filename by default and support `title:`, `author:`
and `topic:` in the query string (both like the template `query` already
does). Fixes remaining issue in #815, reported by Gennadiy.
testsuite:
* Expand omegatest. All scriptindex actions now have test coverage.
build system:
* Replace uses of obsolete autoconf macros, fixing warnings if configure is
regenerated with a recent release of autoconf.
portability:
* Don't automatically use _FORTIFY_SOURCE on mingw-w64. Recent mingw-w64
versions require -lssp to be linked when _FORTIFY_SOURCE is enabled, so just
skip the automatic enabling. Users who want to enable it can specify it
explicitly.
Fixes#808, reported by xpbxf4.
* Automatically enable GCC warnings -Wduplicated-cond and -Wduplicated-branches
if using a GCC version new enough to support them. The usefulness of
-Wduplicated-cond was highlighted by dcb in #816.
* Fix GCC -Wshadow warning.
* Use clock_gettime() and nanosleep() under modern mingw as these allow higher
precision than what we previously used.
