From cc89083f1177606d4cbbb52f8cdc5e34d0d16f70 Mon Sep 17 00:00:00 2001 From: Rich Megginson Date: Wed, 9 Sep 2009 17:01:49 -0600 Subject: Add update code - make setup-ds.pl -u do updates Updates are implemented in: perl - code that plugs in to setup - scriptlets that are imported into the setup perl interpreter and executed in process, giving access to all of the packages and context provided by setup ldif - applied to instances, in the same manner as ConfigFile directives to setup other - any executable file, shell script, etc. can be invoked, with a limited amount of context from the setup process An update directory is added to the package - /usr/share/dirsrv/update - this directory contains the update files - the update filenames begin with two digits and are executed in numeric order (00 first, then 01, etc. up to 99) which should provide enough flexibility In addition, there are 5 stages of update: pre - invoked before any instance specific code preinst, runinst, postinst - invoked for each instance post - invoked after any instance specific code Example files are provided which demonstrate how to get the context. There are two different modes of operation for update: online - must supply a bind dn and password for each instance - servers must be up and running offline - operates directly on the dse.ldif - servers must be shutdown first A new section is added to the .inf file that can be passed in [slapd-instancename] RootDN = binddn RootDNPwd = bindpw The RootDN is optional - if not supplied, it will get the nsslapd-rootdn attribute from the dse.ldif for the instance. I also fixed some problems with error messages. The pam pta plugin entry was giving object class violations, so I added the missing attributes - note that these are replaced by the plugin code when the plugin is loaded - they are only needed during setup. Fixed usage of $_ - $_ behaves like a dynamically scoped variable - which means if you use it in an outer context, you cannot use it in an inner context, even if it is used in a different function. Rather than attempting to figure out how to use $_ safely in lower level functions, I just removed the use of it altogether, which also makes the code easier to read.
