site-nodes cache reform: use ns_urlsspace instead of brute-force caching.

For OpenACS site with recent versions of NaviServer and XOTcl2,

cache sitenode information much more efficiently by the built-in

URL trie, which supports tree match operations, for

tree information. This means that for example for .vuh

handlers it is not necessary to cache the full url for

obtaining the site-node, like it was until now:

3839 id-/storage/view/installers/windows-installer/installer.htm

3839 id-/storage/view/aolserver/install.tgz

3839 id-/storage/view/tutorial/OpenACS_Tutorial.htm

3839 id-/storage/view/openacs-dotlrn-conference-2007-spring/Methodology_ALPE.pdf

3839 id-/storage/view/xowiki-resources/Assessment.jpg

3839 id-/storage/view/tutorial-page-map.png

...

Providing a single entry like

ns_urlspace set -key sitenode /storage/* 3839

is sufficient.

Why is this needed: current cache sizes of larger sites show 330K

(site A) and 390K (site B) cache entries. Matchbase flushes have to

gor thhrough all these entries, causing long lock times. Running

thhis code at OpenACS.org shows an improvement by a factor of more

than 200x.

Revert massive replacement of empty list creation sentences. The use of '[list]' instead of '{}' adds semantics that could be used for performance improvements in the future, such as using a different internal representation. There is already work in this direction, avoiding the generation of the string representation during comparison of empty strings (huge thanks to Stefan Sobernig for the pointer: https://core.tcl.tk/tcl/info/44527c632ed609c2).

Mark procs as deprecated, which were previously just documented as

deprecated and document recommended versions via @see. These procs

should be moved to *deprecated*.tcl after a while to give people

a chance to react (maybe in 5.11 or 5.12).

site_node::conn_url -> ad_conn

site_nodes_sync -> site_node::init_cache

site_node_id -> site_node::get_node_id -url

Don't hard-code the SiteNodeCache sizes in the library file,

but allow configuration via the config-file.

Example:

#

# Provide tailored sizes for the site node cache in acs-tcl:

#

ns_section ns/server/${server}/acs/acs-tcl

ns_param SiteNodesCacheSize 2000000

ns_param SiteNodesIdCacheSize 100000

ns_param SiteNodesChildenCacheSize 100000

Improve scalability of site-node caches

Some sites have site-node caches with more than 200k site-node entries.

Wild card operations for flushing in these caches can take a while (2-digit ms),

locks on the site-node cache can lock everything. This change separates

the caches with wild-card operations from the parts not requiring these.

improving vor sample data the scalability at least by a factor of 4.

Use lreverse instead of inverting the list manually

Use better idiom to concatenate subnodes

- remove trailing white-space

Allow to delete node_ids having subnodes. This simply triggers unmount and delete

of site node, package instances and all its tree structure as one could do manually,

but packages themself are still responsible to "clean their own mess".
