Play 2.8.20

[mkurz]

The Play Team is happy to announce the release of Play 2.8.20 🥳

❔ Nice, but what about Play 2.9?

It's around the corner, basically some docs, migration guide and release notes missing, but no more pull requests. A first release candidate should follow within days 🤞 Sorry, it took a bit longer and was postponed a couple of times. With the first Play 2.9 RC we will also give an update on how we continue with Akka / Akka HTTP after September 2023.

Small question (sorry to put it here - not sure where else to put it): did something went wrong when publishing the sbt-plugin ?
We're using scala-steward for our dependency upgrades, but did not yet receive any PR's.
When i looked in it's logs it does not find a new version of the sbt plugin, although the artifact is on maven central (https://repo1.maven.org/maven2/com/typesafe/play/sbt-plugin_2.12_1.0/2.8.20/).
However I believe that scala-steward uses maven-metadata.xml to discover the versions and i see that it has not been updated (see https://repo1.maven.org/maven2/com/typesafe/play/sbt-plugin_2.12_1.0/), where for e.g. the main artifact (https://repo1.maven.org/maven2/com/typesafe/play/play_2.13/) it has been updated...

[mkurz]

AFAIK scala-steward relies on coursier to determine the versions. Now looking at this code here, if a maven-metadata.xml is found it will use it, if it is not found, it will list the contents of the directory to figure out the version.
The xml in https://repo1.maven.org/maven2/com/typesafe/play/sbt-plugin_2.12_1.0/ however only contains 2.9.0-M6 and 2.9.0-M5 but is missing all 2.8.x releases... so it seems the problem is there.
AFAIK the xml file is generated by maven central server side, so this is not our or sbt's fault (?) sbt does not even generate the xml file (I think this is still the case): sbt/sbt#3879

I would reach out to the sonatype folks and ask what's going on here, according to https://maven.apache.org/repository/central-metadata.html

Related issues:

• Steward PRing sbt-typelevel updates? typelevel/sbt-typelevel#78
• The maven pattern for sbt plugins is invalid based on the spec sbt/sbt#3410 I don't think that's relevent put in sbt 1.9 thinks changed a bit around this topic, but pretty sure is not related to this problem

Good morning, we are using Play Framework 2.8.20 for Java, and we are facing an issue with a method that we are consuming through an Ajax client. The problem we are encountering is that when executing the transaction, as it is a heavy transaction, the method reaches a point where it spawns another thread and starts its execution again. This leads to the method's execution being duplicated twice, which is a serious issue in production. What can we do to prevent the server from making these double attempts without notifying it?

Please open a specific issue or discussion thread with a minimal reproduction case, or at the very least more debugging/troubleshooting details.
