Summary: following uses too much memory
Initial Comment:
Next too the difficult to reproduce preceding/following bug #1850772
([preceding and following]-sibling:: bug) there is another problem with the
following() axis step .
On the small 1M xmark document the queries listed below all result in a memory
allocation failure of BAT's sized 200M to several G's. I think this example is
so simple it should run on any machine.
count(doc("xmark1.xml")//street[./following::keyword[./following::current]])
count(doc("xmark1.xml")//*[./following::incategory[./following::interest]])
count(doc("xmark1.xml")//*[./following::category]/following::interest)
count(doc("xmark1.xml")//*[./following::incategory[./following::interest]])
count(doc("xmark1.xml")//itemref[./following::phone[./following::africa]])
The first query for instance running the CVS HEAD (28/1-14:00) on SuSe9.3 (1G
RAM)
[EMAIL PROTECTED]:~/scripts/DATA> mclient -lx
xquery>count(doc("xmark1.xml")//street[./following::keyword[./following::current]])
more>MAPI = [EMAIL PROTECTED]:50000
QUERY =
count(doc("xmark1.xml")//street[./following::keyword[./following::current]])
ERROR = !ERROR: GDKload failed: name=06/646, ext=head.priv
!ERROR: PFll_following: could not allocate a result BAT of size
555611000.
!ERROR: PFll_following: operation failed.
xquery>
I added the used xmark document bzipped2 to this report,
Jan.
