[Smartscribo] Fwd: Re: [SS WG] Telco of FRUCT Smart Spaces working group

[dkorzun]

Добрый день.

Итак, redland SIB теперь в официальном релизе
Smart-M3. Можно активно экспериментировать.

Александр, посмотри, что Альфредо пишет
про найденную тобой ошибку, связанную с
запросами SPARQL. Напиши Альфредо, как
ее воспроизвести.

Dear Dmitri and all,

I had two weeks of holiday and i come back just today.

I inform that the redland SIB is now published in the source forge page of
the original smart m3 (it is called alfa version but is sufficiently
stable) We are very happy that there is interest to participate in code
development.

I also inform that the correct version of the LCTableTools.h is that
included in the redland SIB while the version in the latest Piglet SIB is
not working properly.

We have searched a lot for the cause of the crashes with sparql, but we
were not able to replicate the error. Please check the following: 

The sparql queries are sent in the SSAP as textual content of an XML
element. In XML textual content there are 5 forbidden characters that must
be substituted by the correspondent XML entity. We make this substitution
automatically from KPI, but if a query is sent without substitution there
may be anomalous behaviour, perhaps crashes. Can you please check if
sparql
queries with proper substitution still cause SIB crashes? In theory the
wanted behaviour is that correct queries receive an answer and
syntactically wrong queries receive an error message without crashes. All
tests should be done with substitutions of the XML entities and in
particular of the "<" and ">" characters.  
substitutions are:

&    ->   &          this substitution should be the frst to be
applied
'    ->   '
"    ->   "
<    ->   <
>    ->   >

let me know if there are still crashes due to syntactically wrong sparql
queries on which substitutions have been applied.

Thank you very much for signaling the discovered bugs and for
participating in this smart space development activity

Best regards,

Alfredo D'Elia
