Help port more of eco-system to Scala 2.13 #563

adriaanm · 2018-09-27T14:22:35Z

We at Lightbend are seeking to collaborate with OSS project maintainers to help port projects from 2.12 to 2.13. This ticket serves to coordinate the effort -- please comment here with any projects you'd like to nominate (including your own ;-)).

jvican · 2018-09-27T14:51:02Z

Migrating anything that is an sbt and Zinc dependency would help so that we can publish a 2.13 version of the incremental compiler before the release of the RC. We're currently blocked by:

scalatest
sbt-io
sbt-util-logging
scalacheck

sjrd · 2018-09-27T15:38:03Z

I'd like to nominate scala-parallel-collections. ;)

adriaanm · 2018-09-27T16:29:41Z

Haha, of course the parallel collections were already on the list :-)

SethTisue · 2018-09-27T16:43:06Z

as usual, https://github.com/scala/make-release-notes/blob/2.13.x/projects-2.13.md lists published projects and has links to open tickets for projects that haven't published yet

dsilvasc · 2018-09-27T17:49:50Z

Are macwire, com.softwaremill.common:tagging, circe, circe-derivation, twilio's guardrail, sttp, gradle-scoverage, gradle-scalastyle-plugin, wartremover, sangria, and gatling already tracked?

martijnhoekstra · 2018-09-28T07:56:26Z

https://github.com/twitter/util could probably use some help, and is often a deep transitive dependency

martijnhoekstra · 2018-09-28T07:57:43Z

Also, https://github.com/apache/spark

da-liii · 2018-09-28T08:27:50Z

Any guide to port a project from 2.12 to 2.13 ?

I'm willing to work on Apache Spark.

da-liii · 2018-09-28T08:33:08Z

Get the dependents:

$ ./build/mvn -Phive-thriftserver -DskipTests package
$ ls assembly/target/scala-2.12/jars  | grep _2.12 | grep -v spark

Well, Apache Spark depends on ...

jvican · 2018-09-28T09:37:22Z

@sadhen's suggestions are great. I would prioritize those deps to make sure we don't repeat the same mistake with Apache Spark in 2.13. Even if it's not going to be released this year, the closer we are from having a working 2.13 Apache Spark port available, the better.

(I don't know how much does Spark use Scala collections, but if it does I also think it would be a good real-world use case to assess the performance of the new collections.)

szeiger · 2018-09-28T18:29:58Z

If you're porting code to 2.13, check out the presentation on this topic by @julienrf and myself from ScalaDays. For the new collections library we have an updated documentation on scala-lang. For cross-building on 2.12 and 2.13 you may want to use the collection-compat library.

smarter · 2018-10-09T14:41:30Z

It looks like scala/bug#11030 is preventing fs2 and probably other projects from compiling with 2.13: typelevel/fs2#1232, so fixing it would definitely count as helping the ecosystem migrate :).

dsilvasc · 2018-10-15T17:04:31Z

Gatling request: gatling/gatling#3566

slandelle · 2018-10-16T12:00:51Z

Regarding Gatling, we depend on (listing only libs that haven't started supporting 2.13):

fastring
spire (macros)
boopickle
zinc
quicklens

Sciss · 2018-12-10T14:16:03Z

We have a ticket for scala-swing now:

scala/scala-swing#84

Rich2 · 2018-12-11T04:07:59Z

I'd certainly like to see help for Scala-Native. Getting to 2.12 seems to be the big challenge for them. Hopefully 2.12 => 2.13 will be relatively straightforward.

SethTisue · 2019-05-04T01:56:39Z

volunteer to port boopickle? it's blocking http4s and gatling (and perhaps other projects)

skonto · 2019-05-10T10:00:31Z

For spark here is the dependency tree (no profile used, we need to verify with profiles to see what they bring in). Verified @sadhen's list. Pending issues:

Spire.
Chill.
Breeze blocked by the Spire issue.

szeiger · 2019-05-13T16:09:47Z

Spire depends on Algebra which doesn't have a 2.13 release yet. WIP here: typelevel/algebra#226

adriaanm · 2019-05-13T16:12:07Z

See also https://github.com/scalacommunitybuild/algebra/tree/community-build-2.13 (and generally, the same pattern of branch name in that org for many projects)

adriaanm · 2019-05-16T13:43:59Z

FYI, 2.13.0-RC2 is tagged and on Maven Central! We'll announce after the weekend.

adriaanm · 2019-05-27T12:51:58Z

Looks like spire and algebra are up to date with 2.13.0-RC1, and I don't expect RC2 to be an issue for them!

adriaanm · 2019-05-27T12:57:05Z

For chill & breeze, we should start with twitter-util and scrooge, which are already in the community build. To see the errors, grep for [twitter-util] [error] in https://scala-ci.typesafe.com/job/scala-2.13.x-integrate-community-build/2208/consoleText.

martijnhoekstra · 2019-05-27T13:30:39Z

I have a WIP for twitter-util at twitter/util#248 -- would particularly appreciate ideas for https://github.com/twitter/util/pull/248/files#r279409022

dsilvasc · 2019-05-27T13:59:09Z

Looks like monadless isn't in the community build. There's a question about 2.13 support here: monadless/monadless#9

Philippus · 2019-05-27T13:59:58Z

Any reason scalamock is not pointing to https://github.com/paulbutcher/ScalaMock ?

SethTisue · 2019-06-19T03:49:45Z

over at https://github.com/scala/make-release-notes/blob/2.13.x/projects-2.13.md I'm not really doing any more maintenance on the list of what is published for 2.13 (except merging PRs on it), but I am definitely maintaining the list of "please publish for 2.13" tickets at https://github.com/scala/make-release-notes/blob/2.13.x/projects-2.13.md#pending, so that's a place to look for projects to help upgrade

Spire has a 0.17.0-M1 release which is available for Scala 2.13

SethTisue · 2019-07-09T21:10:38Z

this is an open-ended/never-ending task, but I think this ticket has now served its purpose. thanks all!

SethTisue · 2020-01-21T04:14:49Z

I'm continuing to maintain https://github.com/scala/make-release-notes/blob/2.13.x/projects-2.13.md — it lists projects that are known not to support 2.13 yet

rafalmag · 2020-03-09T16:27:56Z

I would like to nominate zinc (see sbt/zinc#697) , which seems to block gatling (see gatling/gatling#3566).

SethTisue · 2020-03-09T16:53:12Z

@rafalmag I added the link to https://github.com/scala/make-release-notes/blob/2.13.x/projects-2.13.md
