The path starts at $::acs::rootdir. # # RELOADING VOODOO # # To allow for automatically reloading of Tcl libraries, we introduce the # concept of a server-wide "reload level" (starting at zero) stored in # the apm_properties(reload_level) NSV array entry. Whenever we determine # we want to have all interpreters source a particular -procs.tcl file, # we: # # 1) Increment apm_properties(reload_level), as a signal to each # interpreter that it needs to source some new -procs.tcl files # to bring itself up to date. # 2) Set apm_reload($reload_level), where $reload_level is the new # value of apm_properties(reload_level) set in step #1, to the # list of files which actually need to be sourced. # # Each interpreter maintains its private, interpreter-specific reload level # as a proc named apm_reload_level_in_this_interpreter. Every time the # request processor sees a request, it invokes # apm_load_any_changed_libraries, which compares the server-wide # reload level to the interpreter-private one. If it notes a difference, # it reloads the set of files necessary to bring itself up-to-date (i.e., # files noted in the applicable entries of apm_reload). # # Example: # # - The server is started. apm_properties(reload_level) is 0. # - I modify /packages/acs-tcl/utilities-procs.tcl. # - Through the package manager GUI, I invoke # apm_mark_version_for_reload. It notices that utilities-procs.tcl # has changed. It increments apm_properties(reload_level) to 1, # and sets apm_reload(1) to [list "packages/acs-tcl/utilities-procs.tcl"]. # - A request is handled in some other interpreter, whose reload # level (as returned by apm_reload_level_in_this_interpreter) # is 0. apm_load_any_changed_libraries notes that # [apm_reload_level_in_this_interpreter] != [nsv_get apm_properties reload_level], # so it sources the files listed in apm_reload(1) (i.e., utilities-procs.tcl) # and redefines apm_reload_level_in_this_interpreter to return 1. # ##### ### Callback functions are used to control the logging that occurs during ### the execution of any apm_package that uses the -callback argument. ad_proc -public apm_dummy_callback { string } { A dummy callback routine which does nothing. } { # Do nothing! } ad_proc -public apm_ns_write_callback { string } { A simple callback which prints out the log message to the server stream. } { ns_write $string } ad_proc -public apm_body_callback { string } { This callback uses the document API to append more text to the stream. } { append ::__apm_body $string } ad_proc apm_callback_and_log { { -severity Notice } callback message } { Executes the $callback callback routine with $message as an argument, and calls ns_log with the given $severity. } { $callback $message ns_log $severity [ad_html_to_text -maxlen 140 -- $message] } d_proc -private apm_one_package_descendents { package_key } { Returns a list of package keys of all packages that inherit from the given package } { foreach descendent [db_list get_descendents {}] { if { [info exists ::apm_visited_package_keys($descendent)] } { continue } set ::apm_visited_package_keys($descendent) 1 lappend ::apm_package_descendents $descendent apm_one_package_descendents $descendent } } ad_proc apm_build_subsite_packages_list {} { Build the nsv_set cache of all packages which claim to implement subsite semantics.
