Intercept the cornercase of a pretty name made exclusively of invalid characters, which would result in an empty cr_items.name and in an error

Bring SQL inline, cleanup obsolete remarks

Whitespace changes

set the granularity to 5 to support also values like 125% and 175%

Return result as a plain list, rather than forcing a string representation, so that "evil" tags containing e.g. double quotes are properly quoted and list idioms such as lsort executed on this proc's output work properly

The issue was found e.g. in the my-tags includelet

Prefer api to retrieve the acs-kernel id, as this will work also in corercases such as bootstraping of a new OpenACS instance

avoid multiple substitution for question names starting with the same string (e.g. question, question-1)

remove obsolete variable

Whitespace changes

Add callback hooks for archive, unarchive and delete. Thanks to Felix Moedritscher

Tighten ad_page_contract check for item_id

disallow nested composite questions

Extend high-level filtering by providing "-unless" clause in form-field class "form_page"

- added "unless" clause to form-field class "test_section" to be able to filter

certain pages which should not be included

- reduced redundancy be factor out "compute_filter_clauses" method for FormPage

(used in includelet procs (class "form-usages") and form-field procs (class "form_page")

Revert escaped code

Fix default name

More work on refactoring and streamlining cluster infrastructure

- removed more cases of ad-hoc parsing of IP address and port

- reduced code redundancy

- fixed incorrect comments

- removed obsolete private functions server_cluster_httpget_from_peers

and server_cluster_do_httpget (replaced by acs::clusterwide)

Refactored and streamlined of cluster infrastructure

- base the API new new cluster infrastructure (including memoize-flush, server_cluster_peer_hosts, etc.)

- improved handling for multiple IP addresses and IPv6

- removed assumptions of local vs. global network drivers

- server_cluster_httpget_from_peers not used anymore

Provide a default timeout of 5m to all ns_cache besed caches created via the acs-cache infrastructure

Background: in case, a db entry is to be cached, where the db query

does not finish (e.g. runs into a deadlock), subsequent attempts for

the same value will be blocked as well by the mutex protecting the

entry to be cached. Therefore, later requests to this entry might queue

up in the server. By providing a timeout, this mutex will terminate

latest when the timeout is reached.

The default value for the timeout is set to 5m. In case a certain

cache might issue requests running longer than this, the cache has

to be configured with a larger timeout value.

Use the test machinery to simulate a cookie authentication

improve spelling

reuse util::inline_svg_from_dot in show-object page

Inline sec_login_read_cookie, as it is a private api and would upset the bad calls test
