http://blog.gmane.org/gmane.comp.web.rdf.redland.devel hourly 1 1901-01-01T00:00+00:00 http://gmane.org/img/gmane-25t.png http://gmane.org http://comments.gmane.org/gmane.comp.web.rdf.redland.devel/781 <pre>I've found a bug in raptor_vsnprintf2() (raptor2). Where should I report it? For anyone who's curious, here's the problem:- int raptor_vsnprintf2(char *buffer, size_t size, const char *format, va_list arguments) { size_t len; RAPTOR_ASSERT_OBJECT_POINTER_RETURN_VALUE(format, char*, 0); #ifdef CHECK_VSNPRINTF_RUNTIME if(vsnprintf_is_c99()) VSNPRINTF_C99_BLOCK(len, buffer, size, format, arguments) ; else VSNPRINTF_NOT_C99_BLOCK(len, buffer, size, format, arguments) ; #else #ifdef HAVE_C99_VSNPRINTF VSNPRINTF_C99_BLOCK(len, buffer, size, format, arguments) ; #else VSNPRINTF_NOT_C99_BLOCK(len, buffer, size, format, arguments) ; #endif #endif return RAPTOR_BAD_CAST(int, len); } Note that 'len' is uninitialised when it gets passed to either of the macros (VSNPRINTF_NOT_C99_BLOCK, in my case). In abbreviated form, the macro translates to this code:- #define VSNPRINTF_NOT_C99_BLOCK(len, buffer, size, format, arguments) \ do { \ if(!buffer || !size) { \ /* This vsnprintf doesn't return number of bytes required */ \ size = 2 + strlen(format); \ len = -1; \ /* Do some other stuff (includes setting */ \ /* the correct value for 'len') */ \ } \ \ if(buffer) \ vsnprintf(buffer, len, format, arguments); \ } while(0) The variable 'len' gets passed to vsnprintf() - but if 'buffer' and 'size' both started off with nonzero values, 'len' will contain a garbage value. Hope that makes sense.

The supported query languages are: SPARQL 1.0[3], RDQL (will be removed in 0.9.30), SPARQL Query 1.1[4], SPARQL Update 1.1[5] (no executing) and Experimental SPARQL extensions (LAQRS). Rasqal can write binding query results in the following formats: SPARQL XML, SPARQL JSON, CSV, TSV, HTML, ASCII tables, RDF/XML and Turtle / N3 and read them in: SPARQL XML, RDF/XML and Turtle / N3. Rasqal was designed to work closely with the Redland librdf[1] RDF library and the Raptor[2] RDF Syntax Library but is entirely separate from both. This is a beta quality library - the code is mature, the API is mostly stable but changing slowly. Rasqal supports all of SPARQL 1.0 query and most of SPARQL 1.1 query. It is a portable library and has been tested on multiple POSIX systems and architectures. Rasqal has no known memory leaks. The main changes in this version since the last release 2011-11-17 are: * Supports all of SPARQL 1.0 by passing 100% of the approved tests * Added support for XSD date * Made XSD dateTime and XSD date equality and comparison work * Make limit and offset check work properly in a subquery * Correctly handle errors during aggregation expressions evaluation * Fix blank node generation when made in a CONSTRUCT to match SPARQL * Added SPARQL 1.1 draft UUID() and STRUUID() support * Requires Raptor 2.0.7+ * RDQL support will be removed in the next release (0.9.30) * Made other fixes and improvements including fixing reported issues: 0000493, 0000494 and 0000504 For full details see the Rasqal 0.9.29 release notes at http://librdf.org/rasqal/RELEASE.html#rel0_9_29 rasqal-0.9.29.tar.gz MD5 49e4b75a0c67465edf55dd20606715fa SHA256 8b218dc51b77b99f33103a9251218a4439748f73ee30fa8ee549ab6d150e7c53 The Rasqal API reference manual section on API changes at http://librdf.org/rasqal/docs/api/raptor-changes.html provides detailed function, enum, macro and type changes. Rasqal 0.9.29 requires Raptor 2.0.7[2] or newer to provide RDF syntax, web, XML and URI support. Optional requirements are a POSIX regular expression library such as PCRE or one built into the C library to handle regex matching / replacing; a multi-precision decimal library such as GNU MP or MPFR for handling XSD decimals; a UUID library for generating unique IDs. Binary deb packages for Debian unstable will be made available later via the standard Debian archive.

Fortunately the tarball seems to include some projects for building with Visual C++ 8. Unfortunately, they seem to be quite out of date. In fact AFAICT they're the same projects that originally came with raptor1. Some of the files from raptor1 are no longer supplied with raptor2 (e.g. n3_lexer.c and n3_parser.c) whilst (presumably) some new files might have been added. I appreciate that the VC++ projects have been contributed by a third party but is there anyone who can help me in getting some up-to-date VC++ projects? Also, the file "raptor.h" simply seems to #include "raptor2.h" - but no such file exists in the tarball. Do I need to create it using some pre-build step or something? John </pre> John Emmas 2012-05-07T07:22:18 http://comments.gmane.org/gmane.comp.web.rdf.redland.devel/764 <pre>I found that 'rdfproc --results' always fails, no matter what result type is given: It fails with these packages: http://download.librdf.org/source/raptor2-2.0.7.tar.gz http://download.librdf.org/source/rasqal-0.9.28.tar.gz http://download.librdf.org/source/redland-1.0.15.tar.gz http://download.librdf.org/source/redland-bindings-1.0.14.1.tar.gz The same bug appears in the earlier versions currently in the Ubuntu Oneiric repository. Here is how it fails: $ rdfproc -s postgresql -t "host='localhost',database='red',user='red',password='*'" test query sparql - 'select ?s,?p,?o where { ?s ?p ?o}' --results rdfxml rdfproc: invalid argument `rdfxml' for `-r / --results' Try 'rdfproc -r / --results help' for a list of valid query result formats Try `rdfproc -h / --help' for more information.

It still won't produce results in xml, turtle, or rdfxml, but perhaps those serializers are unimplemented. Leigh. </pre> Leigh L.

It is a mature, portable and high performance library that works across many systems and architectures. It parses the following syntax into RDF triples: RDF/XML, N-Triples, TRiG, Turtle, GRDDL (including microformats hCard and hCal), N-Quads, RDF/JSON resource-format &amp; triples-format and RSS tag soup for RSSes, Atom 0.3 and Atom 1.0. and serializes RDF triples into the following syntaxes: RDF/XML, RDF/XML abbreviated, RDF/XML XMP, N-Quads, N-Triples, Atom 1.0, RSS 1.0, Graphviz DOT, HTML, Turtle and JSON. The changes since the last release on 2011-11-27 are: * CVE-2012-0037 fixed * Removed Expat support * Removed internal Unicode NFC code for better and optional ICU * Added options for denying file requests and XML entity loading * Added options for SSL certificate verifying * Fixed reported issues: 0000448 and 0000469 For full details of the changes see the Raptor 2.0.7 release notes at http://librdf.org/raptor/RELEASE.html#rel2_0_7 raptor2-2.0.7.tar.gz MD5 699073463467dc8eded2ca89de2ab2ea SHA256 d546588f2fc7d1f7c8da7865cec6d9b7d0a95ef6a4393cc9136f3eeb55f28442 The Raptor 2 API reference manual section on API changes at http://librdf.org/raptor/api/raptor2-changes.html provides detailed function, enum, macro and type changes.

Steps to Reproduce: % cat try.ttl &lt; at &gt;prefix x: &lt;urn:example.org#&gt;. &lt;#foo&gt; a x:Type.dot . % rapper -iturtle try.ttl rapper: Parsing URI file:///path/try.ttl with parser turtle rapper: Serializing with serializer ntriples &lt;file:///path/try.ttl#foo&gt; &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns#type&gt; &lt;urn:example.org#Type&gt; . rapper: Error - URI file:///path/try.ttl:3 - syntax error rapper: Parsing returned 1 triple % Additional Information: The file &lt; at &gt;prefix x: &lt;urn:example.org#&gt;. &lt;#foo&gt; a x:Type.dot. should work, too, with the last IRIref being &lt;urn:example.org#Type.dot&gt; ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-03-21 15:49 normang New Issue ====================================================================== </pre> Mantis Bug Tracker 2012-03-21T15:49:04 http://comments.gmane.org/gmane.comp.web.rdf.redland.devel/751 <pre>Hello, I'm trying to execute a DELETE WHERE query. Since it does not do anything, I'm trying to find the problem using roqet. I'm trying the example from http://www.w3.org/TR/sparql11-update/#deleteWhere # cat &gt; t.ttl &lt; at &gt;prefix foaf: &lt;http://xmlns.com/foaf/0.1/&gt; . &lt;http://example/william&gt; a foaf:Person . &lt;http://example/william&gt; foaf:givenName "William" . &lt;http://example/william&gt; foaf:mbox &lt;mailto:bill&lt; at &gt;example&gt; . &lt;http://example/fred&gt; a foaf:Person . &lt;http://example/fred&gt; foaf:givenName "Fred" . &lt;http://example/fred&gt; foaf:mbox &lt;mailto:fred&lt; at &gt;example&gt; . ^D # roqet -W 100 -i sparql11-update -D t.ttl -e "PREFIX foaf: &lt;http://xmlns.com/foaf/0.1/&gt; DELETE WHERE { ?person foaf:givenName 'Fred'; ?property ?value }" But all I get is: roqet: Running query 'PREFIX foaf: &lt;http://xmlns.com/foaf/0.1/&gt; DELETE WHERE { ?person foaf:givenName 'Fred'; ?property ?value }' roqet: Query execution failed Do you know how I could know what's wrong ? I tried searching for DELETE in bug tracker but did not find anything.

But, after getting errors trying to use some functions such as fn:substring (having the fn prefix declared inside the query) I've decided to take a look at Virtuoso's log (after enabling Virtuoso log features using trace_on()) To my surprise, although I successfully retrieve results, some of the queries I perform are not logged at all, and other queries are similar to the ones I intend to pose but are not the same. Moreover, I've tested my queries using Virtuoso Conductor web client and they run as expected. So, my questions are the following: is librdf doing some parsing or re-writing on my queries? Is it somehow "loading" the model from Virtuoso and using its own querying capabilities to execute my queries? If so, how can I skip this step in order to force Virtuoso to process the queries? thanks in advance Lorena </pre> lorena 2012-03-21T00:40:56 http://comments.gmane.org/gmane.comp.web.rdf.redland.devel/746 <pre>Dear All, I have created and parsing the xml database into sqlite database using bellow command. # rdfproc -s sqlite database_name parse file:/home/guest/Documents/sample.xml after firing the following command, the following big error message is generating. so please any one could help to get out of this problem. errror: rdfproc: Error - SQLite database database_name SQL exec 'SELECT 1 FROM triples WHERE subjectUri=-1 AND predicateUri=-1 AND objectUri=-1 LIMIT 1;' failed - no such table: triples (1) rdfproc: Error - SQLite database database_name SQL exec 'SELECT id FROM uris WHERE uri = 'file:/home/odtone/Documents/MIHF/odtone/odtone/app/miis_rdf_server/URL_TO_BE_ASSIGNED#ie_poa_subnet_info';' failed - no such table: uris (1) rdfproc: Error - SQLite database database_name SQL exec 'SELECT id FROM uris WHERE uri = 'URL_TO_BE_ASSIGNEDie_identifier';' failed - no such table: uris (1) rdfproc: Error - SQLite database database_name SQL exec 'SELECT id FROM literals WHERE text = '0x10000204' AND language IS NULL AND datatype IS NULL ;' failed - no such table: literals (1) rdfproc: Error - SQLite database database_name SQL exec 'SELECT 1 FROM triples WHERE subjectUri=-1 AND predicateUri=-1 AND objectLiteral=-1 LIMIT 1;' failed - no such table: triples (1) Best Regards BaBu </pre> Baba Prasad 2012-03-20T18:41:31 http://comments.gmane.org/gmane.comp.web.rdf.redland.devel/745 <pre> The following issue has been SUBMITTED. ====================================================================== http://bugs.librdf.org/mantis/view.php?id=498 ====================================================================== Reported By: jmfernandez Assigned To: ====================================================================== Project: Redland Language Bindings Issue ID: 498 Category: api Reproducibility: always Severity: major Priority: normal Status: new Binding Language (java, perl, php, python, ruby, tcl): ruby ====================================================================== Date Submitted: 2012-03-07 15:47 Last Modified: 2012-03-07 15:47 ====================================================================== Summary: 'parse_string_into_model' calls 'parse_string_as_stream' with an incorrect number of parameters in Ruby binding Description: In Ruby binding, instance method 'parse_string_into_model', from Redland::Parser class, internally calls method 'parse_string_as_stream' with an incorrect number of parameters when: a) parse_string_into_model is called with the 'context' parameter set to something which is not nil. b) Redland::Parser instance has a context.
