"Macro Recorder" for patch installation
---------------------------------------
Key: KARAF-890
URL: https://issues.apache.org/jira/browse/KARAF-890
Project: Karaf
Issue Type: Improvement
Components: karaf-shell
Reporter: Brian Topping
Priority: Trivial
I had this idea so I thought I would share it. I don't believe I have the
skills to implement it (yet), but thought I would at least get it out of my
head so I don't forget it.
When applying changes to an instance that I would like to replicate across
multiple nodes and/or otherwise notate the changes I made, it might be helpful
to have something like a "macro recorder" that can monitor my changes, record
them in a replay file, allow the file to be edited, and play the the file back.
Even in many nodes clustered in a single cluster (the changes should
propagate), any changes would likely be tested in a test cluster first and that
file committed to SCM, and the ability to apply the exact changes that were
committed to SCM could provide the immediacy of the command-line with the
reproducibility of a more structured environment.
>From an implementation perspective, if the actions of the different commands
>that change Karaf's state were firing events, it should be very simple to
>implement all this. I think it would be good that the recorder automatically
>kept a list of macros rather than requiring special setup or explicit saving.
>That way, macros could form "quick notes" whereby if someone was doing
>something they wanted to remember, they could just start the macro recorder,
>and when they stopped it, if they didn't do anything, it would still
>automatically persist their work until such time they did something with it.
