No, a bug in the code:
BAT doc_firstpre is [oid,int]., i.e., its tail is int, not oid, and int != oid;
pathfinder/modules/pftijah/pftijah.mx-73-.COMMAND pf2tijah_node(
pathfinder/modules/pftijah/pftijah.mx-74- BAT[oid,str]
doc_name,
pathfinder/modules/pftijah/pftijah.mx:75: BAT[oid,int]
doc_firstpre,
^
pathfinder/modules/pftijah/pftijah.mx-76- BAT[oid,oid]
pfpre,
pathfinder/modules/pftijah/pftijah.mx-77- BAT[oid,oid]
item,
pathfinder/modules/pftijah/pftijah.mx-78- BAT[oid,int]
kind,
pathfinder/modules/pftijah/pftijah.mx-79- BAT[oid,str]
doc_loaded)
pathfinder/modules/pftijah/pftijah.mx-80- : BAT[void,oid]
= CMDpf2tijah_node;
pathfinder/modules/pftijah/pftijah.mx-81- "Translate Pathfinder node sequence
to tijah node sequence"
hence, to access the tail in C, you (obviously!) need to use
int doc_start = *(int*) BUNtail(doc_firstpre,r);
^^^ ^^^
if (for what ever reason) doc_start needs to be of type oid instead of int, you
need to use
oid doc_start = (oid) *(int*) BUNtail(doc_firstpre,r);
^^^ ^^^^^^
(as you do below);
in fact, you should first check, whether the respective tail value of
doc_firstpre is
not negative, before you caat it to oid!

NOPE!
either
int doc_end = *(int*) BUNtail(doc_firstpre,r) - 1;
or
oid doc_end = (oid) (*(int*) BUNtail(doc_firstpre,r) - 1);
plus a check, whether *(int*) BUNtail(doc_firstpre,r) is > 0 !

We were aware of this tail type and that's why we created the cast. Henning
was a bit hesitant to change the bat type to [oid,oid] because he expected
problems with '<' and '>' so we decided to create the extra cast. The value
can never be negative so we never checked for this. We could make it an
assert();
Furthermore the text //64bit ERROR was to remind us of our own error on 64bit
oid arch's and not an error of monetdb.

Clean and proper use of types should prevent such problems; "arbitrary" casting calls for such (and other) problems. Hence, choose the proper types at all places, and cast as little as possible.

[Monetdb-developers] MonetDB Release Preparation
Dear fellow MonetDB developers/users, we plan to have a new release of the MonetDB software family within the next two weeks, i.e., Feature Freeze: Friday Jun 01 2007 Release:Monday Jun 11 2007 This release cycle is used to reduce the component dependencies, such that we are better prepared to release individual components more frequently. A synopsis of what to expect: MonetDB 5 beta status is dropped and it becomes the sole back-end for the SQL front-end. SQL now supports Persistent Stored Modules. XQuery Update Facility has undergone a large series of stress tests to improve correctness, performance and robustness against concurrent updates. Many bug-fixes based on highly appreciated feedback from our user community. The priorities set for post-release actions as agreed upon by the development team are: shortterm:(summer) SQL GIS geometry model testing and release SQL/XML support development and release PF/SQL exploration (research focus) Skyserver demo website (target 2.7TB online demo) midterm: (fall) Remote SQL execution in a cluster setting SQL adaptive partitioning of large databases XQuery Algebra -> MIL compiler Date/time support in XQuery MonetDB Private BATs policy (kernel modification) lngterm: (fall/spring) XQuery Algebra -> MAL compiler public release of StreetTivo for collaborative media analysis Of course, as always, progress in each of these areas depend on availability of resources and their contribution to our research agenda. We are looking forward to messages from projects based on/exploitation of the MonetDB platform. We plan to add a section in the website to make this work more broadly visible. regards, Martin - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
