I'm very happy to announce the release of ht://Dig 3.1.0. This release is
the result of a lot of work by many people. It represents a considerable
effort to release a very stable version.
Release notes for htdig-3.1.0 9 Feb 1999
This version marks the "full release" of version 3.1.0. Naturally,
this version adds a few new feature and fixes a large number of
remaining bugs. This version is the latest stable release of ht://Dig
and is recommended for all production servers for current bug-fixes
and oft-requested features.
NOTE: You must rebuild your databases from scratch after updating
to this version. Several database-related bugs were fixed and will
remain unless you rebuild from scratch. We're sorry for any
inconvenience.
* Fixed a variety of small memory leaks.
* Fixed a bug that could duplicate documents in the document
databases.
* Fixed a bug that would not remove documents marked as deleted.
* Fixed a bug that could dump core with incorrectly defined
template_map attributes.
* Fixed a bug that could dump core or produce bogus dates when a
server returns the date in an incorrect format.
* Fixed a variety of string-matching bugs that caused problems with
restricting indexing and searching.
* Fixed a bug that could dump core if logging searches and CGI
environment variables were not set.
* Fixed a bug that would not hilight searches properly if they
contained punctuation.
* Fixed PDF parsing to support programs beyond acroread.
* Fixed a bug that caused problems with large robots.txt files.
* Fixed a bug in the sample rundig script from a non-portable test
for the age of databases.
* Fixed bugs in the fuzzy matching code that could prevent searches
from completing if fuzzy databases were not present.
* Fixed bugs in the soundex and metaphone algorithms that would only
return the first word of several matching words. Note that to
completely fix this bug, you must rebuild your soundex and
metaphone databases.
* Fixed up many compilation warnings and errors.
* Fixed a performance slowdown in htsearch when backlink_factor
and date_factor are zero and can be ignored.
* Improved performance when a server ignores the If-Modified-Since
request during update digs.
* Added a warning message if the locale: option is set to a locale
that is not present.
* Some minor performance improvements.
* Allow "include" keyword in config file to include other config
files.
* Uses latest (2.6.4) version of the Berkeley database.
* Two databases may be merged together using htmerge.
* The htdig program can be safely stopped and restarted in the
middle of a dig. The dig will write the progress to the file
specified by the new url_log option.
* Added support for anchors in excerpts with the
add_anchors_to_excerpt option and the ANCHOR template variable.
* Added support for sorting results in increasing or decreasing
order of document date, size, title and score using the search
form. Note that changing sort from the default of score will
result in a performance decrease.
* Added config options sort and sort_names to change the
default sort and names used in the SORT template variable.
* Added the option compression_level to compress the document
database if the zlib library is present.
* Added the options noindex_start and noindex_stop to
delimit sections of HTML documents to be ignored.
* Added the option allow_in_form to allow specific config
options to be set in the search form.
* Added the option bad_querystr to ingore URLs containing
specified CGI queries.
* Added the option search_results_wrapper to replace separate
header and footer files. For mor information, see the general
htsearch documentation.
* Added option no_title_text to allow configuration of the text
used when no title is found.
* Added option url_part_aliases to allow rewriting portions of
URLs.
* Added option common_url_parts to compression common portions
of URLs. Requires rebuilding databases when changed.
* Added option remove_default_doc to control whether ht://Dig
strips off the default document in a folder. Set to empty will
prevent problems with servers that treat / and /index.html as
different URLs.
* Of course there are many other bug-fixes and small enhancements.
Many thanks to everyone who reported a bug or contributed code for
this release!
