<h2 id="rel2_0_16"><a name="rel2_0_16">Raptor2 2.0.16 changes</a></h2>
<p>Not yet released.
</p>
<h3>Serializer changes</h3>
<p>Added a serializer for the
<a href="http://contextknowledgesystems.org/CKS.html">mKR (my Knowledge Representation)</a>
language with the name <code>mkr</code. Patch developed by Richard
H. McCullough based on the Turtle serializer. Thanks.
</p>
<h3>Other changes</h3>
<p>Made some code changes to quiet GCC extra warnings.</p>
<p>Some portability fixes were made for building under cygwin from
Richard H. McCullough while developing the mkr serializer.
</p>
<h2 id="rel2_0_15"><a name="rel2_0_15">Raptor2 2.0.15 changes</a></h2>
<p>This release mainly made general bug fixes as well as several
fixes to the Turtle / N-Triples family of parsers and serializers. It
added utility functions for re-entrant sorting of objects and
sequences and a few other useful methods.<br />
</p>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=574">0000574</a>: Language tags with underscore</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=575">0000575</a>: Wrong API or wrong API documentation</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=576">0000576</a>: Wrong assert for a counted string being nul terminated</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=577">0000577</a>: iri parsing does not conform to REC-n-quads-20140225</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=579">0000579</a>: raptor_world_generate_bnodeid accepts world not parser</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=581">0000581</a>: My patch for parser and serializers count</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=584">0000584</a>: raptor fails to parse trig files with dos line endings</li>
</ul>
<h3>Parser changes</h3>
<p>Fixed <code>raptor_grddl_filter_triples()</code> check for three
URIs which has been broken since 2007 but just did more work. Found
via gcc5 warning.</p>
<p>The TRiG parser now accepts \r newlines between the graph name and
the following '{'.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=584">Issue #0000584</a>
</p>
<p>Turtle, TRiG, N-Triples and N-Quads parsers now check escapes
correctly for URI strings. \t \b \n \r \f are forbidden. Check that
raw ' ' or \u0020, \u003C or \u003E are also not accepted.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=577">Issue #0000577</a>
</p>
<p>N-Triples / N-Quads parsers nwo accept '_' as an alias for '-' in
lang strings. '_' is not legal.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=574">Issue #0000574</a>
</p>
<p>Updated RDFa parser (librdfa) to support full URLs for
<code>typeof</code> from upstream. Re-checked several tests which
have been passing for some time but the expected output was not a
correct conversion from the testsuite sparql.</p>
<h3>Serializer changes</h3>
<p>Turtle serializer now writes <code>()</code> instead of
<code>rdf:nil</code> via
<a href="https://github.com/dajobe/raptor/pull/16">Pull Request #16</a>
from Richard H. McCullough. Thanks!
</p>
<h3>I/O-stream class changes</h3>
<p><code>raptor_iostream_decimal_write()</code> and
<code>raptor_iostream_hexadecimal_write</code> now return non-0 if
they do not succeed in writing successfully.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=575">Issue #0000575</a>
</p>
<h3>Term class changes</h3>
<p><code>raptor_new_term_from_blank()</code> now also accepts "" as
the same as a NULL blank node ID argument.</p>
<h3>URI class changes</h3>
<p>Fixed <code>raptor_uri_counted_filename_to_uri_string()</code> to
use the passed in len, not look for end NUL char and count lengths.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=576">Issue #0000576</a>.
</p>
<p><code>raptor_new_uri_from_counted_string()</code> no longer
assumes a NUL terminated string. Remove a debug assert and use
<code>fwrite()</code> to emit the counted URI string to the debug
file handler.</p>
<p>Fixed <code>raptor_uri_normalize_path()</code> to check the size of
output buffer is big enough.</p>
<h3>Writer class changes</h3>
<p>Fixed <code>raptor_turtle_writer_quoted_counted_string()</code> to
use the passed in length, drop the <code>strlen()</code> call and use
the length internally.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=576">Issue #0000576</a>.
</p>
<h3>World class changes</h3>
<p>Added <code>raptor_world_get_parsers_count()</code>
and <code>raptor_world_get_serializers_count()</code>
with patch from Victor Porton. Thanks!
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=581">Issue #0000581</a>.</p>
<h3>Other Changes</h3>
<p>Made raptor work with Travis CI again; have to download and
install Bison 3.</p>
<p>Added <code>raptor_sort_r()</code> and
<code>raptor_sequence_sort_r()</code> re-entrant sort utility methods
based on the public domain <a
href="https://github.com/noporpoise/sort_r">sort_r</a> code by Isaac
Turner.
</p>
<p>Ensure <code>raptor_locator_format()</code> always adds a NUL to
terminate the output string.</p>
<p>Fix a -99 <= var <= 99 timezone interval check. Thanks to
Richard Trieu for the report.</p>
<p>Improve configure warning check using AC_LANG_WERROR</p>
<p>Use C99 <code>__FUNCTION__</code> replacing <code>__func__</code>
from C90.</p>
<p>Improve build-time flex and bison output to be more silent.</p>
<p>Added Intel C compiler (icc) support from Sebastian Freundt
(hroptatyr on GitHub) - Thanks.</p>
<h2 id="rel2_0_14"><a name="rel2_0_14">Raptor2 2.0.14 changes</a></h2>
<p>Many code quality fixes from clang and coverity primarily in error
path cleanups (out of memory cases) and dead code.</p>
<h3>Parser changes</h3>

and
<a href="http://lists.w3.org/Archives/Public/public-rdf-comments/2014Feb/0021.html">expected answer</a>.
</p>
<h3>Other changes</h3>
<p>Fixed RDFa 1.0 and RDFa 1.1 test suites to properly report
failures.</p>
<p>Updated the fix-flex and fix-bison scripts to remove dead
code that clang and coverity complain about.</p>
<h2 id="rel2_0_13"><a name="rel2_0_13">Raptor2 2.0.13 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=562">0000562</a>: N-Quads parsing of URIs with ' fails</li>
</ul>
<h3>Parser changes</h3>
<p>The N-Triples / N-Quads parser was updated to allow ' in URIs.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=562">Issue #0000562</a>.
</p>
<h3>Configuration changes</h3>
<p>Use the discovery of the <code>xml2-config(1)</code> /
<code>curl-config(1)</code> programs as test for presence of the
libraries. This fixes the issue where that after configuring, curl
was present but was not used for WWW fetching. This is seen when
the output of <code>curl-config --cflags</code> is empty / whitespace.
</p>
<p>Updated to use the <code>AC_CHECK_PROGS</code> macro to find jing
since <code>AC_CHECK_PROG</code> doesn't default to setting it as
found when present!
</p>
<h3>Internal changes</h3>
<p>The Turtle and parsedate parsers and the turtle lexer were updated
to use and require Bison 3.0.0.
</p>
<p>The JSON and turtle writers were updated to save several expensive
<code>strlen()</code> calls.</p>
<h2 id="rel2_0_12"><a name="rel2_0_12">Raptor2 2.0.12 changes</a></h2>
<h3>Parser changes</h3>
<p>The N-Triples / N-Quads parser was updated to pass all the two test
suites for the updated specifications:
</p>
<ul>
<li><a href="http://www.w3.org/TR/2013/CR-n-triples-20131105/">RDF 1.1 N-Triples - A line-based syntax for an RDF graph</a>, W3C Candidate Recommendation, 05 November 2013 (aka N-Triples 2013)</li>
<li><a href="http://www.w3.org/TR/2013/CR-n-quads-20131105/">RDF 1.1 N-Quads - A line-based syntax for an RDF datasets</a>, W3C Candidate Recommendation, 05 November 2013</li>
</ul>
<p>The main fixes were:</p>
<ul>
<li>allow <code>\b</code> and <code>\f</code> escapes (from Turtle, SPARQL)</li>
<li>fix the allowed blank node identifier characters</li>
<li>require all URIs to be absolute</li>
<li>handle a single short document with no end of line</li>
<li>support NULs inside literals</li>
<li>handle unescaped newlines inside literals</li>
</ul>
<h3>Term class changes</h3>
<p>Added <code>raptor_new_term_from_counted_string()</code> to
create a term from a Turtle or N-Triples string syntax. This is
the opposite of <code>raptor_term_to_turtle_counted_string()</code>
and <code>raptor_term_to_turtle_string()</code> and also reads the
strings created by <code>raptor_term_to_counted_string()</code> and
<code>raptor_term_to_string()</code>.
</p>
<h2 id="rel2_0_11"><a name="rel2_0_11">Raptor2 2.0.11 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=556">0000556</a>: Problem with relative URI in rdf:about, rdf:resource etc.</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=554">0000554</a>: RDF/XML serializer does not canonicalize attribute order in XMLLiterals</li>
</ul>
<h3>Parser changes</h3>
<p>N-Triples parser was updated to support all of
<a href="http://www.w3.org/TR/2013/CR-n-triples-20131105/">RDF 1.1
N-Triples - A line-based syntax for an RDF graph</a> (aka N-Triples 2013)
It now supports <code># comments</code> after the end of
lines, checks for illegal unicode escapes, checks for bad URIs and
checks language tags.
Also removed support for legacy N-Triples
<code>"foo"-LANGTOKEN</code>.
Many internal changes were also made.
</p>
<p>RDF/XML parser fixed the XML Canonicalization so that it writes
the XML attributes in sorted order.
Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=554">Issue #0000554</a>.
</p>
<h3>URI class changes</h3>
<p>Added <code>raptor_uri_uri_string_is_absolute()</code> to
check if a URI is absolute.</p>
<h3>QName class changes</h3>
<p>Added <code>raptor_qname_format_as_xml()</code> to turn a qname
into an XML declaration.
</p>
<h3>Configuration and build changes</h3>
<p>Restructured code to build an internal librdfa convenience library
(never installed) so that newer automake will stop moaning about
subdir-objects.
</p>
<p><code>configure</code> now checks for clang to correctly find
supported warnings.</p>
<p>Various portability and build fixes (Daniel Richard G)</p>
<p>Build fixes: <code>make check</code> will now work if jing is not
installed (for feed XML generation validation).
</p>
<h3>Other changes</h3>
<p>Fixed a few issues found with LLVM 3.4 (SVN) run with address
sanitizing.</p>
<h2 id="rel2_0_10"><a name="rel2_0_10">Raptor2 2.0.10 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=532">0000532</a>: configure.ac: required file `src/raptor_config.h.in' not found</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=535">0000535</a>: configure accepts bogus values for --with-xml2-config</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=545">0000545</a>: Reopen issue 503</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=548">0000548</a>: xml:lang inside rdf:parseType="Literal" are removed in parsed output</li>
</ul>
<h3>Parser changes</h3>
<p>Turtle parser was updated to handle
<a href="http://www.w3.org/TR/2013/CR-turtle-20130219/">Turtle Terse RDF Triple Language</a> W3C Candidate Recommendation 19 February 2013
(Turtle 2013)
The main changes were to align with SPARQL-style blank node names,
prefixes and local names.
</p>
<p>N-Triples parser was updated to handle
<a href="http://www.w3.org/TR/2013/NOTE-n-triples-20130409/">N-Triples - A line-based syntax for an RDF graph</a> W3C Working Group Note 09 April 2013 (N-Triples 2013)
The main changes were to allow \b \f, UTF-8 in strings and
URIs and the SPARQL-style blank node names.</p>
<p>RDF/XML parser updated to understand the new RDF 1.1 datatypes:
rdf:HTML and rdf:langString</p>
<h3>Serializer changes</h3>
<p>Updated N-Triples and Turtle serializers (via writers) for 2013
versions based on SPARQL 1.1 definitions. These new formats
have incompatible changes.
</p>
<p>Added functions for writing escaped Turtle / N-Triples terms:</p>
<pre>
int raptor_string_escaped_write(const unsigned char *string,
size_t len, const char delim, unsigned int flags, raptor_iostream *iostr);
int raptor_term_escaped_write(const raptor_term *term, unsigned int flags,
raptor_iostream* iostr);
int raptor_uri_escaped_write(raptor_uri* uri, raptor_uri* base_uri,
unsigned int flags, raptor_iostream *iostr);
</pre>
<p>These uses the new new <code>raptor_escaped_write_bitflags</code>
enum bitflag values for the <code>flags</code> argument.</p>
<p>Deprecated <code>raptor_string_python_write()</code> for
<code>raptor_string_escaped_write()</code> with flags.</p>
<h3>Configuration and build changes</h3>
<p><code>configure</code> now recommends flex 2.5.36</p>
<p><code>configure</code> was updated to switch configuring libxml
and libcurl to use the <code>PKG_PROG_PKG_CONFIG</code> and
<code>PKG_CHECK_MODULES</code> macros. The preference remains to
prefer looking for the xml2-config and curl-config programs before
trying pkg-config unless <code>--with-curl-config=no</code>
<code>--with-xml2-config=no</code> are used.
</p>
<p><code>configure</code> now dies if xml2-config or xslt-config
point at non executable files. Patch from Michael Stahl - thanks.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=535">Issue #0000534</a>
</p>
<p><code>configure</code> now adds curl or libxml pkg-config requires
only if they were found via pkg-config; this prevents unnecessary
dependency on pkg-config files if they are not needed.</p>
<p>Updated autogen.sh and code to handle variations of header
macro.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=532">Issue #0000532</a>
</p>
<h2 id="rel2_0_9"><a name="rel2_0_9">Raptor2 2.0.9 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=499">0000499</a>: Turtle parser fails to correctly parse valid syntax</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=508">0000508</a>: Raptor objects to possibly valid Turtle syntax</li>

<h3>Parser Changes</h3>
<p>RDFa parser:
Handle non-namespaced elements without crash in RDFa.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=521">Issue #0000521</a>
</p>
<p>Turtle Parser: Added full support for
<a href="http://www.w3.org/TR/2013/CR-turtle-20130219/">Turtle Terse RDF Triple Language</a> W3C Candidate Recommendation 19 February 2013
</p>
<p>This includes accepting new keywords from SPARQL
(<code>BASE</code> and <code>PREFIX</code>), triples forms and
details of the characters allowed in URIs, Literals, Prefix Names,
Local Names and Blank Node identifiers. Some existing documents that
used <code>\</code>-escapes in URIs to encode characters not allowed
in URIs, are now forbidden. For example ASCII 32 (0x20) - space,
which should be written as <code>%20</code>.
</p>
<h3>Serializer changes</h3>
<p>Turtle Serializer: Added full support for
<a href="http://www.w3.org/TR/2013/CR-turtle-20130219/">Turtle Terse RDF Triple Language</a> W3C Candidate Recommendation 19 February 2013
which particular effects the encoding of URIs in the serializer.
</p>
<h3>Configuration and build changes</h3>
<p>Added CMake build framework for building Raptor on Microsoft
Windows. Removed the old <code>win32/</code> area and
<code>win32_raptor_config.h</code> references. Contributed by Daniel
Richard G. for Teragram Inc.
</p>
<p>Ensure that a small system BUFSIZ does not affect parser guessing
Patch from Daniel Richard G for Teragram Inc.</p>
<p>Added a compile-time check for
<code>raptor_world_guess_parser_name()</code> to ensure that
<code>RAPTOR_READ_BUFFER_SIZE</code> is at least as large as
<code>FIRSTN</code>, because otherwise the guesser sees fewer than
<code>FIRSTN</code> bytes from the document. Patch from Daniel
Richard G for Teragram Inc.
</p>
<p>Update <code>configure</code> to allow xml2-config and curl-config
to work for libxml and libcurl. It now report on the source of xml, curl
libraries in the configuration status.</p>
<p><code>autogen.sh</code> updates to abort the run if a configuring
program fails, Generate NEWS with old timestamp if missing so
automake can run.</p>
<p>Handle the libxml2 <code>ret->checked</code> field not being
present in older libxml2 versions. The entities checked field was
added 2006-10-10 in <a href="http://git.gnome.org/browse/libxml2/commit/?id=a37a6ad91a61d168ecc4b29263def3363fff4da6and">libxml2 GIT commit a37a6ad91a61d168ecc4b29263def3363fff4da6and</a>

Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=520">Issue #0000520</a>
</p>
<h3>Other changes</h3>
<p><code>raptor_www_set_ssl_verify_options()</code> now supports the
Curl 7.28.1 removal of <code>CURLOPT_SSL_VERIFYHOST</code> with a
value of 2. Now <code>verify_host</code> non-0 means to verify CN, 0
means to not verify.</p>
<p>Remove <code>-m MODE</code> from the <code>rapper(1)</code> help
message which was removed in commit
f94fa561db05b21132b14a2b72f05b77e666c252 on Wed Apr 28 21:31:54 2010
-0700 as part of the Raptor V2 work.
</p>
<h2 id="rel2_0_8"><a name="rel2_0_8">Raptor2 2.0.8 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=381">0000381</a>: Raptor incorrectly serializes turtle lists when list nodes are URIs.</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=487">0000487</a>: Does raptor_world_guess_parser_name [librdf_parser_guess_name2] ever return NULL?</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=505">0000505</a>: Parsing certain escaped unicode strings in Turtle cases an error</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=507">0000507</a>: Turtle parse error causes fatal error</li>
</ul>
<h3>Parser class changes</h3>
<p>Guessing a parser with
<code>raptor_world_guess_parser_name()</code> now returns NULL failure
when the guess is very poor, rather just return the first bad result.
Fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=487">Issue #0000487</a>
which was reported in <a href="http://librdf.org/">Redland librdf</a> but
is implemented here.
</p>
<p>Guess parser: now returns error file and line location information
from the guessed parser.</p>
<p>RDFa parser: Updated <a href="https://github.com/rdfa/librdfa">librdfa</a>
to the latest GIT supporting
<a href="http://www.w3.org/TR/2012/REC-rdfa-core-20120607/">RDFa 1.1</a>
with 30 tests still not passing - mostly issues in the core librdfa.
Made several resilience and crash fixes. Updated the RDFa 1.0 test
suite to latest tests and made fixes. The RDFa parser now accepts
aliases 'rdfa10', 'rdfa11' and the default 'rdfa' is RDFa 1.1
</p>
<p>RSS tag soup parser: Use <code>time()</code> when
<code>gettimeofday()</code> is not available. Fix several reference
leaks.
</p>
<p>RDF/XML parser: The range of RDF/XML entity recognizing heuristic was
broadened to allow recognition of documents produced by Stanford's
Protege software (and possibly others). Fixed some parser memory
leaks / double frees.
</p>
<p>Turtle parser: Do not report multiple errors for Turtle string decoding
problems. When a Turtle qname cannot be found, a fatal error is no
longer generated but a regular error message giving information on
the qname that failed (usually due to unknown prefix).
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=507">Issue #0000507</a>
</p>
<h3>SAX2 API changes</h3>
<p><code>raptor_sax2_inscope_xml_language()</code> will now return ""
for explicit no language (<code>xml:lang=""</code>) as well as NULL
for undefined language (no <code>xml:lang</code> present).
</p>
<h3>Serializer class changes</h3>
<p>Turtle: Do not emit a Turtle <code>(...)</code> collection if the
list item is a URI. This fixes
<a href="http://bugs.librdf.org/mantis/view.php?id=381">Issue #0000381</a>.
</p>
<h3>Term class changes</h3>
<p>Added <code>raptor_term_to_turtle_counted_string()</code> counted
string form of <code>raptor_term_to_turtle_string</code>.
</p>
<h3>Unicode class changes</h3>
<p><code>raptor_unicode_utf8_string_put_char()</code> and
<code>raptor_unicode_utf8_string_get_char()</code>
now allow reading / writing U+D800 to U+DFFF (UTF-16 surrogates).
rather than returning failure. BOMs remain forbidden - definitely not UTF-8.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=505">Issue #0000505</a>
</p>
<h3>URI class changes</h3>
<p>Fixed URI resolving with reference (relative) URIs that are bare
queries like '?y' with no path. Now matches the specification
RFC3986 section 5.4.1 Normal Examples.
</p>
<p>Added <code>raptor_new_uri_relative_to_base_counted()</code>
to construct URI relative to current base.
</p>
<p>Added <code>raptor_uri_to_turtle_counted_string()</code> counted
string form of <code>raptor_uri_to_turtle_string</code>.
</p>
<h3>WWW class changes</h3>
<p>The Curl WWW implementation now interprets
<code>Content-Location</code>code> header as absolute or relative URI.
</p>
<h3>Configuration and build changes</h3>
<p>All configure --with-foo options now handle --without-foo (and
--with-foo=no) to disable attempting to find the value in the PATH.
This can be used with --with-xml2-config, --with-xslt-config,
--with-curl-config, --with-icu-config and --with-libwww-config where
the value 'no' or --without-foo can be used to disable it and prevent
automatic searches for the config script in the PATH.
</p>
<p>The <code>-DRAPTOR_DEBUG</code> and <code>-DMAINTAINER_MODE</code>
flags are now written to the config header instead of added to
CPPFLAGS.
</p>
<p>The <code>-g</code> flag is no longer added to CFLAGS or CPPFLAGS
with <code>--enable-debug</code>.</p>
<p>The existing <code>--disable-release</code> (default) now
correctly removes -O options in flag variables for the maintainer.
</p>
<p><code>autogen.sh</code> now looks for the environment variable
<code>NOCONFIGURE</code> to prevent it running configure at the end
of the auto generation run.
</p>
<p>The <code>configure</code> vsnprintf() check was made more
comprehensive.
</p>
<h3>Other changes</h3>
<p>Multiple portability improvements to vsnprintf code and macros.
Also fixed uninitialized variable problems in non-c99 variant of
raptor_vsnprintf2(). Thanks to John Emmas for reporting.
</p>
<p>Multiple portability fixes for building out of the source tree.
Out of source tree 'make check' and 'make dist' should both work.
Thanks to Daniel Richard G. for the patches.
</p>
<p>Multiple portability fixes for building on old Solaris versions.
Thanks to Daniel Richard G. for the patches.
</p>
<p>Multiple portability fixes for building on Windows including
strcasecmp(), windows headers, configuration fixes, parsedate code,
URI test builds, vsnprintf building. Thanks to Daniel Richard G.
for the patches.
</p>
<p>Updated the example <code>rdfguess</code> to accept a file called
or no arguments to read from stdin.</p>
<h2 id="rel2_0_7"><a name="rel2_0_7">Raptor2 2.0.7 changes</a></h2>
<p>CVE-2012-0037 fixed</p>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=448">0000448</a>: Turtle parser does not return error status from turtle_parse_chunk()</li>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=469">0000469</a>: Allow rapper to bypass server SSL certs checks in libcurl</li>
</ul>
<p>Removed Expat support since expat has not had a release in years
and libxml2 works well. This allows some code simplification.
Updated <code>configure</code> so that if Raptor is configured with
no parser that requires an XML parser, libxml2 will not be required.
</p>
<p>Removed internal Unicode NFC checking code used for checking
RDF/XML literals conformance which was expensive to check and a large
of compiled-in static dataset that was rather out of date. Replaced
with optional compiled use of <a href="http://www.icu-project.org/">ICU</a>.
If ICU is not explicitly configured, no literal checking is done.</p>
<h3>Options changes</h3>
<p>Added new options:</p>
<dl>
<dt><code>RAPTOR_OPTION_NO_FILE</code><br/></dt>
<dd>Deny file requests during parsing. Enabled by default.</dd>
<dt><code>RAPTOR_OPTION_LOAD_EXTERNAL_ENTITIES</code><br/></dt>
<dd>Allow loading of XML external entity loading. Disabled by
default.</dd>
<dt><code>RAPTOR_OPTION_WWW_SSL_VERIFY_PEER</code><br/></dt>
<dd>Controls verifying an SSL peer during parsing / WWW. Takes an
integer value: non-0 to verify peer SSL certificate (default
1).</dd>
<dt><code>RAPTOR_OPTION_WWW_SSL_VERIFY_HOST</code><br/></dt>
<dd>Controls verifying an SSL host during parsing / WWW. Takes an
integer value: 0 none, 1 CN match, 2 host match (default). Other
values are ignored.</dd>
</dl>
<h3>Parser class changes</h3>
<p>The RDF/XML, RSS Tag Soup and RDFa parsers now pass on network,
file and entity loading parser options to the internal SAX2 to enable
enforcing of network, file and entity loading policy.</p>
<p>RDF/JSON parser handles an API change between YAJL V1 and V2.
</p>
<p>Turtle parser now returns parser errors to
<code>raptor_parse_chunk()</code>.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=488">Issue #0000488</a>
</p>
<h3>SAX2 class changes</h3>
<p>Added <code>raptor_sax2_set_uri_filter()</code> to set a URI
filter for any SAX2 calls that do internal lookups of URIs.
</p>
<p>Control file and network loading inside SAX2. Option
<code>RAPTOR_OPTION_LOAD_EXTERNAL_ENTITIES</code> now enforces
loading external XML entities and is by default enabled. If enabled,
<code>RAPTOR_OPTION_NO_FILE</code> and
<code>RAPTOR_OPTION_NO_NET</code> are also checked. All URIs loaded
are also passed through any URI filter, if set by
<code>raptor_sax2_set_uri_filter()</code>.
</p>
<h3>URI class changes</h3>
<p>Added new URI constructor
<code>raptor_new_uri_from_uri_or_file_string()</code>
to build a URI from a URI string or a filename string, normalizing
the result to a <code>file:</code> URI.
</p>
<p>Added
<code>raptor_uri_uri_string_to_counted_filename_fragment()</code> to
turn a URI string to a filename and URI fragment along with string
output string counts.
</p>
<p>Added utility methods for checking if a file: URI or filename is a
file that exists:
<code>raptor_uri_file_exists()</code> and
<code>raptor_uri_filename_exists()</code>
</p>
<h3>WWW class changes</h3>
<p>Added <code>raptor_www_set_ssl_verify_options()</code> to set SSL
verify options.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=469">Issue# 0000469</a>.
</p>
<p>The <code>raptor_www_fetch()</code> call now returns the status
from any URI filter that returns a non-0 response.
</p>
<h3>Build changes</h3>
<p>Added <code>--with-icu-config=</code><em>PATH</em> option
to enable use of ICU for NFC checking.</p>
<p>Requires automake 1.11.2+ for <code>-Wextra-portability</code></p>
<p><code>configure</code> uses <code>AM_PROG_AR</code> to make
automake <code>-Wextra-portability</code> happy.
</p>
<h2 id="rel2_0_6"><a name="rel2_0_6">Raptor2 2.0.6 changes</a></h2>
<p>Fixed expat support which was broken in 2.0.5</p>
<p>Handle libCurl SSL options before 7.16.4 (that's 2007) since old
libcurl is still around on Enterprise (that means old) linux systems.
</p>
<h3>Sequence Changes</h3>
<p>Added utility functions to swap elements, reverse the sequence and
generate permuations:</p>
<pre>
int raptor_sequence_swap(raptor_sequence* seq,
int i, int j);
int raptor_sequence_reverse(raptor_sequence* seq,
int start_index, int length);
int raptor_sequence_next_permutation(raptor_sequence *seq,
raptor_data_compare_handler compare);
</pre>
<h2 id="rel2_0_5"><a name="rel2_0_5">Raptor2 2.0.5 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=465">0000465</a>: c99 snprintf usage</li>

</ul>
<h3>Parser class changes</h3>
<p>Updated all parser URIs to use the
<a href="http://www.w3.org/ns/formats/">W3C Format URIs</a>
as the primary URIs. Existing URIs become aliases. (Nicholas J Humfrey)
</p>
<p>GRDDL parser: Correctly set the base_uri when resolving the

When guessing formats, make N-Quads always beat N-Triples since
since now all ntriples parse fine with the nquads parser. (Lauri Aalto)
</p>
<p>RDFA parser: fix when building with 64-bit systems to prevent
value truncation.</p>
<p>Turtle parser: now uses the official <em>text/turtle</em> mime
type in the syntax recognizing code.
</p>
<h3>Serializer class changes</h3>
<p>Updated all serializer URIs to use the
<a href="http://www.w3.org/ns/formats/">W3C Format URIs</a>
as the primary URIs. Existing URIs become aliases. (Nicholas J Humfrey)
</p>
<p>Turtle serializer now uses the official <em>text/turtle</em> mime
type in the syntax recognizing code.
Do not generate infinite output when the input Unicode UTF-8 encoding
is bad.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=481">Issue #000481</a>.
</p>
<h3>Unicode class changes</h3>
<p>Added new utility functions for calculating number of Unicode
characters in a UTF-8
string <code>raptor_unicode_utf8_strlen()</code> and getting a subset
of a UTF-8 string <code>raptor_unicode_utf8_substr()</code>:
</p>
<pre>
int raptor_unicode_utf8_strlen(const unsigned char *string,
size_t length);
size_t raptor_unicode_utf8_substr(
unsigned char* dest, size_t* dest_length_p,
const unsigned char* src, size_t src_length,
int startingLoc, int length);
</pre>
<h3>URI class changes</h3>
<p><code>raptor_uri_string_to_relative_uri_string()</code> now
compares URI paths not files. (Joe Presbrey)
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=472">Issue #0000472</a>
</p>
<h3>Build changes</h3>
<p>The library no longer needs <code>trunc()</code>,
<code>lround()</code>, <code>round()</code> or anything else from
libm. Removed the checks for these functions from
<code>configure</code>.
</p>
<p><code>configure</code> no longer enables debug messages by default
for <code>--enable-maintainer-mode</code> but now requires the
<code>--enable-debug</code> option to be given.
</p>
<h3>Other changes</h3>
<p>Records GIT version in the version string when building from GIT
sources with <code>--enable-maintainer-mode</code>. This makes it
clearer when an non-released version is being used.
</p>
<p>Added internal <code>raptor_format_integer()</code> which enabled
the removal of all internal use of <code>snprintf()</code>.
</p>
<p>Added <code>raptor_vsnprintf2()</code> deprecating
<code>raptor_vsnprintf()</code> which does not actually have the
vsnprintf() calling contention. Added <code>raptor_snprintf()</code>
with snprintf() calling convention. Added
<code>raptor_vasprintf()</code> with vasprintf() (GNU) calling
convention.
</p>
<pre>
int raptor_vsnprintf2(char *buffer, size_t size,
const char *format, va_list arguments);
int raptor_snprintf(char *buffer, size_t size, const char *format, ...);
int raptor_vasprintf(char **ret, const char *format, va_list arguments);
</pre>
<p><code>raptor_locator_format()</code> now picks a large enough
buffer size if <code>snprintf()</code> is likely not portable, when
HAVE_C99_VSNPRINTF is not defined.
Fixes <a href="http://bugs.librdf.org/mantis/view.php?id=465">Issue #0000465</a>
</p>
<p>Internal code style changes for how allocation is done and casting
with new macros.</p>
<blockquote>
<p>RAPTOR_GOOD_CAST: code checks or logic ensures cast will not
truncate</p>
<p>RAPTOR_BAD_CAST: value may be truncated; may require API
change/break. Might be unrealistic e.g. a >4G error message,
qname prefix.</p>
<p>Some good uses:</p>
<ul>
<li>narrowing a known, checked unicode char to a U16</li>
</ul>
<p>Some 'bad' uses:</p>
<ul>
<li>only handing error messages, literal language, qname prefixes of
a max len constrained by int</li>
<li>passing in data to libxml constrained by int max len</li>
<li>locator column field constrained to int size</li>
</ul>
<p>Some bad uses:</p>
<ul>
<li>iostream read_bytes and write-bytes methods return int but could
easily return a lot more in the size_t range (compare to fread).
API change needed.</li>
<li>locator byte field constrained to int size. should be size_t</li>
<li>raptor_nfc_check returns int offset into a buffer that could
be larger</li>
<li>raptor_ntriples_parser_context changed line_length and offset
to size_t</li>
<li>raptor_turtle_parser changed buffer_length to size_t</li>
</ul>
</blockquote>
<p>Updated code to use <code>size_t</code> for sizes such as those
from <code>strlen()</code> and <code>ptrdiff_t</code> for pointer
differences so that on 64-bit architectures, values are not
potentially truncated to size of int.

<h2 id="rel2_0_4"><a name="rel2_0_4">Raptor2 2.0.4 changes</a></h2>
<p>Issues Fixed:</p>
<ul>
<li><a href="http://bugs.librdf.org/mantis/view.php?id=308">0000308</a>: undefined reference to round and trunc while cross compiling for mipsel</li>

<h3>Parser class changes</h3>
<p>The <code>raptor_option</code> enumeration gains values for
setting SSL client side certificates:
<code>RAPTOR_OPTION_WWW_CERT_FILENAME</code> for the certificate
filename, <code>RAPTOR_OPTION_WWW_CERT_TYPE</code> for the
certificate type and <code>RAPTOR_OPTION_WWW_CERT_PASSPHRASE</code>
for the certificate passphrase.
</p>
<p><code>raptor_parser_parse_uri_with_connection()</code> (which is
called by <code>raptor_parse_uri()</code>) now uses
<code>raptor_www_set_ssl_cert_options()</code> to turn the parser
options above into settings on the WWW object.
</p>
<p>RDF/JSON parser: Gains support for building with
<a href="http://lloyd.github.com/yajl/">YAJL</a> V2. Note that YAJL
V1 and V2 both install the same library name 'libyajl' even though
they have different ABI and APIs.</p>
<p>TRiG parser: Fixed to support the legal <em>uri</em> <code>:
{</code> ... <code>}</code> syntax naming a graph where the
'<code>:</code>' is optional.
</p>
<p>Turtle parser: Modified to not include the internal
<code>input()</code> function in the lexer which is never needed.
