5 Union on nodes in temporary trees - ID: 441078

Last Update: Comment added ( mhkay )

Details:

Nodes in temporary trees do not have an identity that
is unique within the entire transformation. This means
that two nodes in different temporary trees may be
regarded as the same node for the purposes of the
union operator "|" (i.e. node may be regarded as
duplicates when they are not, leading to missing nodes
in the result).

Also, the result of generate-id() may not be unique.

Raised by Paul Boocock [paulb@ashridgetech.com]

Cause: Temporary trees are not registered in the
Controller's DocumentPool, which is used to decide
whether two documents are distinct.

Present since 6.4.

Date: 2001-11-12 17:24 Sender: mhkay Logged In: YES user_id=251681 Revised fix: the DocumentPool has been rewritten so it no longer keeps a pointer to the DocumentInfo object, but only its hashcode. This will not prevent the DocumentInfo being removed from memory by the garbage collecter. - MHK

I suspect the fix for this bug is causing temporary trees not to be garbage collected. Evidence raised by Janning Vygen [vygen@planwerk6.de] on xsl-list, 16/10/2001.
