Two bugs, one in the map Javascript and one in the node calculation
backend, were combining to produce slow operation of Google Maps for
some users. The attached patch rectifies these issues by fixing the
Javascript bug and disabling the offending node calculation method.
Note: this fix introduces a new (aesthetic) bug. Child nodes and
network links will appear as usual, but if the other endpoint of a
link is remote (i.e., not a child of the branch being viewed) its
node will not be drawn. This does not occur very often, and can only
be seen by zooming Google Maps out; nonetheless, if it is important
to anyone please let me know and I will see what I can do. A more
permanent fix for this problem will be included in Zenoss 2.1.1.
To apply the patch, copy the file to $ZENHOME/Products. From that
directory, run:
patch -p0 < googleMapsFix.patch
It will patch two files. Then, as the zenoss user, restart Zope:
zopectl restart
