Acquisition loops and web robots
by Andrews, Martin 11 Jan '01

11 Jan '01

I have run into several cases where authors at our site have accidentally employed acquisition to link documents in such a way that an infinite tree of URLS are possible - for example: /a/foo contains a link to "b/bar" /b/bar contains a link to "a/foo" This really causes a problem with our web indexer (htdig) hits the site and indexes pages like: /a/b/a/b/a/b/a/b/a/b/a/b ... a/foo Has anyone found a way to avoid these sort of problems - other then just not indexing zope sites? I already limit htdig with the max_hop_count setting, but that it tricky to tune correctly (and still index all valid files). Martin --- Martin Andrews mandrews(a)netgenics.com

Linux implements threads by processes that share memory and other resources. "ps" is still a bit stupid and does not visualize that they are threads rather than normal (full blown) processes. Dieter

Shane, You are DA MAN. That getPhysicalPath() & unrestrictedTraverse() methods work perfectly, even with SiteAccess installed. Thank you very much.

Store object2.getPhysicalPath(), which returns a tuple, in object1. To find object2 again, call object1.unrestrictedTraverse(stored_physical_path). Note that this only works in Zope 2.2.x+.

[newbie] sqltest question
by Martin Fekete 11 Jan '01

documentation says that sqlvar support expressions <dtml-sqlvar Variable|expr="VariableExpression"> and this works <dtml-sqlvar "'%'+arg+'%'" type=string> but documentation also says that sqltest support expressions <dtml-sqltest Variable|expr="VariableExpression"> so this should work <dtml-sqltest "'%'+arg+'%'" type=string column=arg> but it's not working ... any ideas ? thanks Martin Fekete

To properly reference your frames by their absolute urls, instead of this: <frame name="A" src="<dtml-var top>"> <frame name="B" src="<dtml-var main>"> Try this: <frame name="A" src="<dtml-var "top.absolute_url()">"> <frame name="B" src="<dtml-var "main.absolute_url()">"> -PSJ
