FYI, on the tdom leak, I found that my app (BookMooch) was leaking as
well (thanks for mentioning the leak problem you're having, it helped
me find mine), and the reason is that tdom NEVER automatically
releases memory for the documents it creates (the docs say " the
document object command has to be explicitly deleted ").
Therefore, I highly recommend adding a
$doc delete
to manually delete any tdom objects you create.
Below are the relevant docs for tdom for this.
-john
dom parse ?options? ?data?
Parses the XML information and builds up the DOM tree in memory
providing a Tcl object command to this DOM document object. Example:
dom parse $xml doc
$doc documentElement root
parses the XML in the variable xml, creates the DOM tree in memory,
make a reference to the document object, visible in Tcl as a document
object command, and assigns this new object name to the variable doc.
When doc gets freed, the DOM tree and the associated Tcl command
object (document and all node objects) are freed automatically.
set document [dom parse $xml]
set root [$document documentElement]
parses the XML in the variable xml, creates the DOM tree in memory,
make a reference to the document object, visible in Tcl as a document
object command, and returns this new object name, which is then
stored in document. To free the underlying DOM tree and the
associative Tcl object commands (document + nodes + fragment nodes)
the document object command has to be explicitly deleted by:
$document delete
or
rename $document ""
