Xapian-core 1.2.15 (2013-04-16):
API:
* QueryParser/TermGenerator: Don't include CJK codepoints which are
punctuation in N-grams.
* TermGenerator: Fix bug where we failed to generate the first bigram
from the second sequence of N-grammable CJK characters in a piece of text.
brass backend:
* Call fdatasync()/fsync() when creating the "iambrass" file.
chert backend:
* Call fdatasync()/fsync() when creating the "iamchert" file.
flint backend:
* Call fdatasync()/fsync() when creating the "iamflint" file.
tools:
* delve: If -v is specified more than once, show even more info in some cases.
Xapian-core 1.2.14 (2013-03-14):
API:
* MSet::get_document(): Don't cache retrieved Document objects unless they
were requested with fetch(). This avoids using a lot of memory when many
MSet entries are retrieved. (Fixes#604)
matcher:
* Check if a candidate document has at least the minimum weight needed
before checking positional information, which speeds up slow phrase
searches (partly addresses #394).
brass backend:
* Fix multipass compaction not to damage document values, and to merge the
database stats correctly. (fixes#615)
chert backend:
* Fix multipass compaction not to damage document values, and to merge the
database stats correctly. (fixes#615)
flint backend:
* Fix multipass compaction bug. (fixes#615)
tools:
* xapian-replicate:
+ Fix handling of delays between replication events - the subtraction of the
target time and the current time was reversed, so we wouldn't sleep when
before the deadline, but would sleep after it for the amount we'd missed it
by.
+ On Microsoft Windows, we no longer sleep for more than 43 years if the
target time for a replication event had already passed. (Fixes#472)
Xapian-core 1.2.13 (2013-01-09):
API:
* TermGenerator: Add new method TermGenerator::set_max_word_length() to allow
this limit to be adjusted by the user.
* QueryParser: Implicitly close any unclosed brackets at the end of the query
string. Patch from Sehaj Singh Kalra.
* DateValueRangeProcessor: Add extra constructor overloaded form so that in
DateValueRangeProcessor(1, "date:"), the const char * gets interpreted as
std::string rather than bool.
matcher:
* Improved fix for #590 - count all matching LeafPostList objects with a Weight
object rather than trying to prune at the MultiAndPostList level based on
max_wt (if wdf is always zero for a term, BM25 gives max_wt of 0, which lead
to us never counting that subquery.
* Fix calculation of 0.0/0.0 in some cases. This then got used as a minimum
weight, but it seems this gives -nan (at least on x86-64 Linux) so it may
have been harmless in practice.
* We no longer use the highest weighted MSet entry to calculate percentages, so
remove code which finds it.
brass backend:
* Close excess file handles before we get the fcntl lock, which avoids the
lock being released again if one is open on the lock file. Notably this
avoids a situation where multiple threads in the same process could succeed
in locking a database concurrently.
chert backend:
* Close excess file handles before we get the fcntl lock, which avoids the
lock being released again if one is open on the lock file. Notably this
avoids a situation where multiple threads in the same process could succeed
in locking a database concurrently.
flint backend:
* Close excess file handles before we get the fcntl lock, which avoids the
lock being released again if one is open on the lock file. Notably this
avoids a situation where multiple threads in the same process could succeed
in locking a database concurrently.
remote backend:
* Improve the UnimplementedError message for a MatchSpy subclass which doesn't
implement name() so it's clearer that it is this particular subclass which
can't be used remotely, rather than all MatchSpy objects.
documentation:
* valueranges.html: Update documentation to reflect change in Xapian 1.1.2 -
DateValueRangeProcessor and StringValueRangeProcessor now support a prefix or
suffix.
* Clarify that the "reverse" parameter of set_sort_by_relevance_then_value()
and set_sort_by_relevance_then_key() only affects the ordering of the
value/key part of the sort.
* docs/quickstart.html: Fix seriously outdated statement that Xapian doesn't
create the database directory - that changed in 0.7.2 (released 2003-07-11).
* HACKING: Try to make it clearer we're looking for a dual-licence on submitted
patches.
tools:
* xapian-replicate:
+ Add a --full-copy option to force a full copy to be sent. (ticket#436)
+ Add --quiet option, and be a little more verbose by default.
+ Allow files > 32G to be be copied by replication.
+ Fix "if (fd > 0)" tests in some replication code to be "if (fd >= 0)".
In practice this is unlikely to actually have caused problems since
stdin is typically still open and using fd 0.
+ Simplify how we open the .DB file on the replication slave to just call
open() once with O_CREAT, rather than once without, than stat() if that
fails, and then again with O_CREAT|O_TRUNC if stat() doesn't show an
ordinary file exists.
examples:
* quest:
+ New --flags command line option to allow setting arbitrary QueryParser
flags.
+ Align option descriptions in --help output, and make the initial letter of
such descriptions consistently lowercase.
