Check dformat 18-21.

Pleas port relevant parts of ExecuteResult class.

If the user does not have W access on routines db he will not be able to edit it.

Also the  whole DB might be marked as RO.

Create your own context class and redefine getDisplayList there. Docs.

Dmitriy is correct but for your specific use case (auto-removed globals) use Process Private Globals as they are automatically deleted on process end.

Do you want to search at storagetime or at runtime?

%Compiler package can do that but it's not supported.

Reimport linked table.

looks interesting.

OEX link does not work.

This is useful if you need to debug class methods where you can't use $$$TRACE

Add

Include Ensemble

to the start of your class and all Ensemble specific macros become available.

Restarting only the modified Business Host is enough.

Check the docs for SQL Gateway.

Just need to figure out (or take an advice!) how to exclude, say, system classes outright.  

Something like this should work:

WHERE 1=1
      AND NOT name %STARTSWITH '%'
      AND NOT name %STARTSWITH 'CSP'
      AND NOT name %STARTSWITH 'Ens'
      AND NOT name %STARTSWITH 'INFORMATION.SCHEMA'

Pinging @Michael Brady.
 

Will they compare INT's or CLS's, given it's about CompiledClass?

No idea. Do you think someone might have edited generated int code directly?

I think this is a task better suited for Version Control System, such as git.

1. Export all relevant code from the first namespace
2. Commit
3. Export all relevant code from the second namespace 
4. Diff

And for CD/CI systems such as Jenkins, GitHub or GitLab.

That said you can use this SQL to compare class hashes (if hashes are identical than classes are identical)

SELECT
  Name,
  Hash,
  TimeChanged,
  TimeCreated
FROM %Dictionary.CompiledClass

After that you can use this SQL to compare hashes of the individual methods (if classes do not match):

SELECT
  parent,
  Name,
  RuntimeHash
FROM %Dictionary.CompiledMethod
