performant multi-run support #169

Any thoughts on this one? Would be really useful to know whether such functionality can be eventually accepted and whether this is the right approach for it. Thank you. |
Yes please. It is not just about comfort when reviewing diffs; if we ever need to |

Would be helpful to @link to register and unregister so callers can see how to use it.

Deserves Javadoc at least for the loader parameter, which in evaluate is nontrivial.

Better implement Closeable and make this the close method, so PreparedScript can be used in a Java 7+ try block.

Note to self: register and unregister calls should be cheap enough that they contribute no significant overhead.

This should be in a finally block, not a catch block (or just use Closeable trick mentioned above).

strange that I did this, I'll check your Closeable suggestion

Hello, updated according to your reasonable comments. Please let me know if you see further possible improvements (or if I missed anything). One question - would the automatic PR test job deploy a timestamped snapshot or does it have to be deployed in some other way? |
Afraid not.
IIRC you just need a jenkins.io account, then I use a helper script: mvn clean install source:jar deploy:deploy -DaltDeploymentRepository=maven.jenkins-ci.org::default::https://repo.jenkins-ci.org/snapshots/ -DskipTestsPlain |
BTW that has been superseded by JEP-305. Docs |

Last I checked, the idea sounded fine but I have not looked at the details. Leaving it to plugin owners.

Hello, I want to be able to run a groovy script many times without needless overhead.
This is needed for me to implement custom log lines processing in Logstash plugin.
At the same time I'd like the convenience and safety of all the magic presently done
by the secure groovy script plugin. This modification is to allow that.
Sorry about white-space changes. It's because of the editor settings. If you don't
want them, I'll go ahead and revert them. Same about the EditorConfig file. Just
thought it is a useful addition.
If you like to keep the removed needless whilte spaces, you could add
?w=1to urlof the file diff to have them filtered out while reviewing:
