An excellent writeup as usual from Mr Haki

The Log4j extras javadocs are here

There's a nice description of the different types of timeouts that can be used with HttpClient at baeldung.com

Was tearing my hair out why this was failing yesterday.
sql.call('{call PACKAGE.MY_STORED_PROC(?,?,?,?,?) }',
[studentId, firstAssignmentDate, lastAssignmentDate, sectionCode, termCode])

The Error:
Message: Invalid column type

It failed with that error after I added some validation code. However, I could copy the code to the Grails Console, and it would work. If I called the Service from the Console, it would not work.

???

Apparently the Stored Procedure functionality of Groovy does not play well with @CompileStatic. I had added that with the validation code as an afterthought, and it was apparently the wrong thing.

Flattery is like cologne -- to be smelled, but not swallowed.

You can use:
COPY TABLE_NAME TO STDOUT WITH CSV HEADER
to push the output to a csv file.

There are multiple ways to do this. I was particularly interested in getting it to run without the additional "groovy " in the front. Silly, but it was interesting.

I found an interesting question on unix.stackexchange.com regarding how to specify the interpreter for a script which came in handy in case you are using gvm (sdktool).

The result
Create a file - myscript.groovy - with contents:

#! /usr/bin/env groovy
println "executing some groovy"

Make the file executable:
chmod +x myscript.groovy

Now we can run it:
./myscript.groovy

Really doesn't save us much from:
groovy myscript.groovy

But it IS possible. It is also documented at docs.groovy-lang.org

Apparently, the goal was to have a format that was readable AND writable by scripts. Makes sense.

You can still create an additional config for the app in grails-app/conf/application.groovy

Interesting Project for performing backups with Bash.

This can happen when going from an https secured site to an http site. The browser does not send the referrer to the server in this instance.
