I tried to create a script to automate the deployment of a single Foswiki application.

In the steps I tried to install an Extension before generating the LocalSite.cfg. This resulted the error below. Although I clearly missed a step, the _stop function also vanished from extension.pl without a trace.

During the change of Item13391 the function declaration was removed but not all instance of its use removed.

The recommended way to do a scripted deployment it by using the tools/configure CLI utility to build the configuration. My autodeployment script looks like:
# Build the initial LocalSite.cfg (Sets all defaults and file system paths)
tools/configure -save -noprompt         
                                     
# The rest of these could all be done on one command They are separated out and whitespace added for clarity
# Set admin password, and also restrict configure to a user.                                                                                                                                             
tools/configure -save -set {Password}='somesecretpassword' 
   -set {FeatureAccess}{Configure}='JoeUser' 

# Set the web paths, including short URLs
tools/configure -save -set {DefaultUrlHost}='http://wiki.mysite.com' 
   -set {PubUrlPath}='/pub' 
   -set {ScriptUrlPath}='/bin' 
   -set {ScriptUrlPaths}{view}='' 

# Configure email  Assumes underlying system is *nix and has sendmail or equivalent available 
-set {Email}{MailMethod}='MailProgram' -set {EnableEmail}=1 
   -set {WebMasterEmail}='JoeAdmin@mysite.com'            
                                                                                                                                                                                
# Configure the page cache
tools/configure -save -set {Cache}{DBI}{MySQL}{Database}='foswiki_db' 
   -set {Cache}{DBI}{MySQL}{Password}='mysqlpassword' 
   -set {Cache}{DBI}{MySQL}{Username}='foswiki' 
   -set {Cache}{Implementation}='Foswiki::PageCache::DBI::MySQL'             

# Set a restricted path 
tools/configure -save -set {SafeEnvPath}='/bin:/usr/bin'

# Check the configuration and report any issues, or file permission errors/warnings
tools/configure -check
tools/configure -check {DataDir} -method validate_permissions
tools/configure -check {PubDir} -method validate_permissions

If you want to run a wizard to autodetect and configure email, this could be used. It will probe the server and figure out the right port & protocol to use to send email.
tools/configure -set {WebMasterEmail}='user@yoursite.com' -set {SMTP}{MAILHOST}='your.smtp.server' -set {SMTP}{Username}='smtpuser' -set {SMTP}{Password}='smtppassword' -wizard AutoConfigureEmail -method autoconfigure

And be sure all of the above all run as the web server user, so that proper ownership of logs, etc are maintained.

GeorgeClark, Thank you for your suggestions. I am definitely going to use them.

Regarding the original task, the extension installer will attempt to "check in" topics into the store, so the installer cannot run unless the store and paths are configured. So for fixing this bug, it probably should still die, but with a meaningful error message that a configuration is required. No need for stack dumps, etc. Setting this task to confirmed.

One thing I omitted in my script demo is I do not set the Store type, so on a pristine install, this will default to the PlainFileStore. So be sure that's what you want or add the -set statements for the {Store}{Implementation}.
