2011-12-14 Dave Beckett <dave@dajobe.org>
* src/rasqal_query_transform.c:
(rasqal_query_remove_empty_group_graph_patterns): Only for GROUP
2011-12-13 Dave Beckett <dave@dajobe.org>
* src/rasqal_datetime.c:
Size of xsd:Date prefix is 6 not 7
2012-02-13 Lauri Aalto <laalto@iki.fi>
* autogen.sh:
require automake 1.11.2+ for -Wextra-portability
2012-02-11 Dave Beckett <dave@dajobe.org>
* configure.ac:
Report raptor version in build summary
2012-02-09 Dave Beckett <dave@dajobe.org>
* src/rasqal_digest_md5.c, src/rasqal_digest_sha1.c,
src/rasqal_internal.h: Added RASQAL_BAD_CAST RASQAL_GOOD_CAST
after raptor
Added it to MD5 and SHA1 calls where a len turns into a size_t
* build/.gitignore: ar-lib
* configure.ac:
Add automake option -Wextra-portability and
AM_PROG_AR to make it happy
2012-02-05 Dave Beckett <dave@dajobe.org>
* INSTALL.html, LICENSE.html, NEWS.html, README.html,
RELEASE.html, TODO.html: 2012
* src/rasqal.h.in, src/rasqal_datetime.c,
src/rasqal_format_html.c, src/rasqal_format_json.c,
src/rasqal_format_rdf.c, src/rasqal_format_sparql_xml.c,
src/rasqal_format_sv.c, src/rasqal_literal.c,
src/rasqal_query_results.c, src/rasqal_query_write.c,
src/rasqal_xsd_datatypes.c: Added RASQAL_LITERAL_DATE for xsd:Date
rasqal_literal_type gains RASQAL_LITERAL_DATE but it is
unfortunately not in the FIRST_XSD to LAST_XSD range so needs it's
own handling.
(rasqal_new_xsd_date): Fix call to rasqal_xsd_datetime_parse() to
unset isDateTime flag.
(rasqal_xsd_check_date_format): Added. Add xsd:date to recognized
datatype URIs in XSD module.
(rasqal_xsd_datatype_uri_to_type, rasqal_xsd_datatype_type_to_uri)
(rasqal_xsd_datatype_check, rasqal_xsd_datatype_parent_type): Add
date support as an XSD type that is not in the FIRST..LAST range.
(rasqal_new_numeric_literal): Handle RASQAL_LITERAL_DATE via
rasqal_new_xsd_date()
(rasqal_free_literal): Updated for date Updated many other methods
to pretty much do the same thing as RASQAL_LITERAL_DATETIME for
RASQAL_LITERAL_DATE.
(rasqal_literal_compare): Use new rasqal_xsd_date_compare
(rasqal_literal_equals_flags): Use new rasqal_xsd_date_equals
(rasqal_literal_cast): Allow casting string to date and date to
string.
2011-12-04 Dave Beckett <dave@dajobe.org>
* src/Makefile.am, src/rasqal_xsd_datatypes.c: Eliminate never
used code in rasqal_xsd_datatypes.c Removed empty test code
* docs/rasqal-changes.tsv, docs/rasqal-sections.txt,
src/rasqal.h.in, src/rasqal_datetime.c, src/rasqal_internal.h: Add
rasqal_xsd_date for XSD:Date
(rasqal_new_xsd_date, rasqal_free_xsd_datetime): Added constructor
and destructor
(rasqal_xsd_date_to_counted_string, rasqal_xsd_date_to_string)
(rasqal_xsd_date_equals, rasqal_xsd_date_compare): Added core
methods
2011-12-03 Dave Beckett <dave@dajobe.org>
* src/rasqal_query_results.c: Fix blank node generation for
constructs
(rasqal_literal_to_result_term): Added, pulled out of
rasqal_query_results_get_triple(). Rewrite blank node IDs to be
prefixed by the result number, only if the original value was a
blank node from the CONSTRUCT otherwise leave it alone.
(rasqal_query_results_get_triple): Use above to turn rasqal values
into raptor terms and constrain to the RDF rules.
2011-11-20 Dave Beckett <dave@dajobe.org>
* configure.ac: search for AWK and use it
2011-11-18 Dave Beckett <dave@dajobe.org>
* src/rasqal.h.in: this is rasqal
2011-11-17 Dave Beckett <dave@dajobe.org>
* NEWS.html, RELEASE.html, configure.ac:
Bumped version to 0.9.29
* Snapshotted rasqal_0_9_28 for 0.9.28 release (GIT
6618f96e1be4693f1f73be138dd94c46ecc98376)
2011-11-16 Dave Beckett <dave@dajobe.org>
* configure.ac:
Make sure raptor is new enough or fail configure
2011-11-15 Dave Beckett <dave@dajobe.org>
* .gitmodules, autogen.sh, configure.ac, libmtwist,
src/Makefile.am, src/mtwist_config.h, src/rasqal_random.c: Add
libmtwist as a submodule to implement random
* RELEASE.html: 0.9.28
* src/Makefile.am: Made git-version.h a non-distributable source
file.
2011-11-14 Dave Beckett <dave@dajobe.org>
* src/rasqal_general.c:
(rasqal_log_error_varargs): Use raptor_vasprintf for raptor >= 2.0.5
2011-10-24 Dave Beckett <dave@dajobe.org>
* src/rasqal_mt_rand.c: Remove rasqal includes
* src/rasqal_mt_rand.c: multiple code style fixes.
2011-10-23 Dave Beckett <dave@dajobe.org>
* src/rasqal_mt_rand.c: RASQAL_MT_MATRIX_A
* src/Makefile.am, src/rasqal_mt_rand.c, src/rasqal_random.c:
Mersenne Twister functions
* configure.ac, src/rasqal_random.c: Use GNU MP random routines if
GMP was configured
* src/rasqal_random.c: Do not cast int to double, let arithmetic
promote it
* src/rasqal_random.c:
(rasqal_new_random): Set initial seed from system
* src/rasqal_expr.c, src/rasqal_expr_numerics.c,
src/rasqal_internal.h, src/rasqal_random.c: Rename random methods;
add double function
(rasqal_random_seed): Renamed from rasqal_random_srand
(rasqal_random_irand): Renamed from rasqal_random_rand
(rasqal_random_drand): Added returning a double Updated callers to
use new names.
2011-10-23 Dave Beckett <dave@dajobe.org>
* INSTALL.html, configure.ac:
Make random approach configurable
Added --with-random-approach=ALGO to select from the choices
It is still an error to have nothing, since rand() is always
available in POSIX.
2011-10-19 Dave Beckett <dave@dajobe.org>
* src/rasqal_random.c: RASQAL_RANDOM_STATE_SIZE
* src/rasqal_random.c: fixes for initstate_r and random_r
