Summary: XQ: Algebra
Initial Comment:
I saw that the algebra was now runtime configurable... (yahoo!!)
I compiled it (last night's current), and ran some queries. Other than that
query performance is much better, I noticed the following:
- The output format for algebra xqueries seems to be 'xml', no matter which
option is supplied to '-f'. (milprint_summer had 'dm' as default)
- Typo: miprintsummer in pathfinder.mx (line: 4385)
"""(GDKgetenv("xquery_backend") == NULL) ||
(strcmp(GDKgetenv("xquery_backend"),"miprint_summer") != 0)))"""
- The function "pf:documents()" is not yet implemented?
- it cannot yet count to 3
QUERY = count(1 to 3)
ERROR = !fatal error: physical algebra equivalent for logical algebra node kind
31 not implemented, yet

the upcoming release is to soon to have the fn:doc-available() ready.
However, it is high on our priority list so it will be there soon.

thanks for the quick replies and fixes.
fn:doc-available() is indeed more useful in most of our cases. will there
be a way in the upcoming version to obtain a list of documents/collections
that are currently stored in the database?
i'll close the bug-report as there are enough tests with 'to' already.
Jan, good night.

Just added support for op:to --- Now you can count until MonetDB crashes
:D
But you have to come up with something more clever than
for $a in (1 to 1000000) return 1 to 1000000
This query only returns the useful error message '!ERROR: CMDcross:
operation failed.' but does not crash MonetDB :-).

- Indeed, the algebra version for now only supports the "xml" serializer.
- Typo in pathfinder.mx is fixed. Thanks for notifying!
- pf:documents() is not yet available in the algebra version.
In fact, we also plan to implement fn:doc-available()
(cf., http://www.w3.org/TR/xpath-functions/#func-doc-available)
which might be more suitable for your purposes than pf:documents() ...
- The algebra version does not yet suppor the "to" operator.
