schema export via reactive driver

[gavinking]

This patch depends on a proposed change to Hibernate core. Please do not merge.

For #104

@vietj @FroMage @Sanne @DavideD WDYT of this?

I want to run Schema Export against the Vert.x driver, but I don't need it to actually be reactive. Also, I don't want to rewrite all of Hibernate's schema export stuff to use CompletionStage or whatever.

This seems to work fine, except with the @RunWith(VertxUnitRunner.class) where sometimes I get a harmless stacktrace from Vert.x at the end of my test.

Is this for some reason a terrible thing to be doing? Is there some other way we should be doing it?

@gavinking What's the stack trace complaining about? Is it the Vertx blocked thread checker? If that's the case, I think we can safely ignore that because we are intending to be blocking here. To silence the blocked thread checker, we could use our own Vertx instance where we can set the blocked thread checker interval to a really high value like so:

    VertxOptions vertxOptions = new VertxOptions();
    vertxOptions.setBlockedThreadCheckInterval(600);
    vertxOptions.setBlockedThreadCheckIntervalUnit(TimeUnit.MINUTES);
    Vertx vertx = Vertx.vertx(vertxOptions);

[gavinking]

Yeah it looks to me like Vert.x shuts down the thread because it thinks it's misbehaving.

Let's try your suggestion. Thanks.

[gavinking]

@aguibert so I looked for a place to set this up in VertxUnitRunner and didn't find anything obvious. @vietj any suggestion?

[gavinking]

@aguibert I think you were searching for this work.

Note that you might be better off with this branch, since it fixes some bugs exposed by this PR.

@gavinking thanks for the pointer. I see that branch requires a snapshot of hibernate core. Should I be building a certain branch from core? Or better yet, is the required snapshot hosted on bintray or similar?

sorry, we no longer deploy nightly snapshots.

Project:

• https://github.com/hibernate/hibernate-orm
  Branch : 5.4

To deploy a snapshot to maven local:

./gradlew publishToMavenLocal

master

To deploy a snapshot to maven local:

./gradlew publishToMavenLocal

That's actually super-slow. I prefer:

./gradlew hibernate-core:publishToMavenLocal

(Though you probably also need hibernate-testing.)

N.B. "master" will most likely work as well, but master is now version 5.5.x - Quarkus uses 5.4.x (as we don't have a stable release of 5.5.x yet) so I'm backporting anything that Reactive needs to 5.4 too. It's also a strategy to keep possibly invasive patches that other might merge into master out of your way ;)
