Since Scala 2.13.2, Scala introduced built-in support to
manage warnings in a more granular fashion, thus making
the silencer plugin we are currently using no longer
strictly useful. Removing compiler plugins also removes
friction from migrating to Scala 3 in the future. As a
cherry on top, the built-in warning configuration also
allows to check whether a `@nowarn` actually does
anything, allowing us to proactively remove unused
warnings should the need arise.
[Here][1] is s a blog post by the Scala team about it.
Warnings have been either solved or preserved if useful,
trying to minimize the scope (keeping it at the single
expression scope if possible). In particular, all
remaining usages of the Scala Collection API compatibility
module have been removed.
Using the silencer plugin also apparently hid a few
remaining usages of compatibility libraries that were used
as part of the transition from Scala 2.12 to Scala 2.13
that are no longer needed. Removing those warnings
highlighted those.

New year, new copyright, new expected unknown issues with various files
that won't be covered by the script and/or will be but shouldn't change.
I'll do the details on Jan 1, but would appreciate this being
preapproved so I can actually get it merged by then.

* Upgrade Scalatest to v3.2.9.
Because of some coupling we also have to upgrade Scalaz to the latest
v7.2 point release, v7.2.33.
The Scalatest changes are quite involved because the JAR has been broken
up into several smaller JARs. Because Bazel expects us to specify all
dependencies and doesn't allow transitive dependencies to be used
directly, this means that we need to specify the explicit Scalatest
components that we use.
As you can imagine, this results in quite a big set of changes. They
are, however, constrained to dependency management; all the code remains
the same.

CHANGELOG_END
* repin 2.12
Ths is required to get a version of Gatling that supports Scala
2.13 (and only that because they do not cross build).
Unfortunately the upgrade is a bit more annoying than I was hoping for:
Our custom gatling utils rely on parsing the simulation log. This is
an internal file format with zero documentation or stabilityt
guarantees and as expected it has changed in incompatible ways during
the upgrade.
Rather than trying to reverse engineer and adapt to changes everytime
we upgrade, this PR switches us to a slightly more supported codepath
by parsing the `stats.json` and `assertions.json` produced by the
highcharts stuff. Afaict this is also what for example the Jenkins
integration relies on so while it’s not completely public API it seems
like the best option I could find.
There are a few pieces of information we can’t get out of those
files. Specifically:
1. maxUsers: we only ever need one users anyway so not really relevant.
2. start, duration, end: no idea why we would want those. we want per
request metrics not the total duration.
3. geometric mean: slightly annoying, but avg & stdev should be good
enough™.
4. The scenario name: Not really an issue but if it is, we can
disambiguate by changing request names.

* check whether collection.compat is unused when compiling for Scala 2.12
- Instead of always suppressing warnings for collection.compat._,
we should only do it for Scala 2.13
- We can also reduce boilerplate by automatically adding this
option when both silencer_plugin and collection-compat are
present

* remove unused import

* missed compat dependency
* more missed compat dependencies
* missed compat dependency
* use scala_deps in scaladoc_jar
- #8423 inlined the major version expansion, but this seems to
have been prior to proper support by scaladoc_jar
* restore custom handling of participant-integration-api
- fixing scaladoc_jar isn't worth it for a single case, as with
deps vs scala_deps
* Switch from `@silent` to `@nowarn`.
This annotation is native to Scala 2.12.13+ and 2.13.2+. It replaces
most usages of `@silent`.
I had to get creative about a couple of use cases that didn't work.
Specifically:
1. Suppressing deprecation warnings works, but Scala 2.12 erroneously
complains that the `@nowarn` is unnecessary. I had to suppress
this warning too with `-Ywarn-unused:-nowarn`.
2. I can't seem to suppress the warning, "The outer reference in this
type test cannot be checked at run time." Instead, I have
refactored the code to remove the warning.
We still need to use the silencer plugin to suppress some warnings about
unused imports (because of compatibility between Scala 2.12 and 2.13),
but this means we no longer need the library, and therefore it is not a
transitive dependency that downstream consumers need to worry about.
CHANGELOG_BEGIN
CHANGELOG_END
* Add some comments around `@nowarn` support.
* language-support/scala: Fix a warning suppression.
* Revert to the default warnings.
Compatibility was complaining.
* Upgrade Scala 2.12 to v2.12.13.
This is being pulled in anyway because of Maven/Gradle/etc's fun
"favor the most recent" resolution mechanism. The version of Akka we
depend upon transitively depends on Scala 2.12.13, so any downstream
consumers will see that as the Scala version required.
Bringing the Daml repo in line means no more confusion.
CHANGELOG_BEGIN
- [Scala Bindings] If you are using Daml on Scala 2.12, it now depends
on Scala v2.12.13 (from v2.12.12).
CHANGELOG_END
* Scala 2.12.13 is the default version in our pinned version of nixpkgs.
* Upgrade Scala 2.13's Wartremover version.
* Rename `scala_version_rule` to `scala_version_configure`.
* Add a test case to ensure the Scala versions are the same everywhere.
* Add tests for the Scala JAR versions in maven_install_*.json
* gatling-utils: Change the sort order of the expected CSV in tests.
I don't know why this changed, but it seems to be stable.
* compatibility: `scala_version` -> `scala_version_configure`.
* Bazel: Disable the Scala version tests on Windows.
* compatibility: Upgrade Wartremover to Scala 2.12.13.
This fixes Scaladoc and our pom file generation.
It also clears up the confusing error around gatling and removes a
redundant dependency on sbt (no idea why we had that in the first
place) both of which resulted in Scala 2.12 dependencies in our 2.13
lockfile which is obviously bad.
With this, we should now be ready to publish Scala 2.13 artifacts once
the ledger API test tool PR lands.

This PR updates scalafmt and enables trailingCommas =
multiple. Unfortunately, scalafmt broke the version field which means
we cannot fully preserve the rest of the config. I’ve made some
attempts to stay reasonably close to the original config but couldn’t
find an exact equivalent in a lot of cases. I don’t feel strongly
about any of the settings so happy to change them to something else.
As announced, this will be merged on Saturday to avoid too many conflicts.

* Upgrade Scala dependencies for 2.13 compatibility
This upgrades a bunch of Scala libraries to versions that have 2.13
support. There are two libraries that are still missing:
- diffson, this has a new version but with significant breaking
changes and it is only used in Naigator console which I hope to kill
before I have to worry about this.
- ai.x:diff, this is used in the ledger API test tool. The library is
abondened but there are a few alternatives.

This is necessary to at least attempt an upgrade to 2.13 and
generally, I want to keep our rulesets up2date. rules-scala forces the
version of scalatest so we have to bump that at the same time.
This requires changes to basically all Scala test suites since the
import structure has changed and a bunch of things (primarily
scalacheck support) got split out.
Apologies for the giant PR, I don’t see a way to keep it smaller.
