This PR changes the release version format for snapshot releases to
allow for an optional "build number", i.e. "how many times have we
screwed up this release before this attempt?".
Adding this to the version string should be fine because:
- It is a number, so GHC will be happy.
- It is dot-separated and (manually) incrementing, so all three formats
will sort it correctly.
- The SemVer->GHC conversion only looks at the beginning and ending of
the snapshot string, and this changes the middle.
This is necessary because sometimes we screw up releases (e.g. #4902),
but also because sometimes releases screw themselves up by somehow
corrupting the Windows cache, and so far changing the version number has
been the only way out of that. So far that has meant changing the target
commit, but that's a very poor reason to choose a target commit.
We should not have to include additional code in a release just because
our release process is flaky.

* ledger-api-test-tool: Fix warnings flagged by IntelliJ IDEA.
* ledger-api-test-tool: Open-world mode.
In open-world mode, parties aren't allocated; their names are just
reserved for the test case, so that no other test will accidentally use
the same party name.
This is so we can test ledgers which dynamically allocate parties, such
as Sandbox.
* sandbox: Run conformance tests in "open-world" mode.
This means that the tests don't explicitly allocate parties (except for
a few), instead relying on Sandbox's implicit party allocation feature.
This is not enabled for Sandbox Next yet.
* sandbox-next: Implicit party allocation.
This is added to the command submission service.
CHANGELOG_BEGIN
CHANGELOG_END
* sandbox-next: Don't implicitly allocate pre-existing parties.
* ledger-api-test-tool: Move pre-allocation into ParticipantTestContext.
* ledger-api-test-tool: We can reserve parties or wait for them. Not both.
Make illegal states unrepresentable as early as possible.
* sandbox: Name ApiSubmissionService's private methods a little better.
* sandbox: Move ApiSubmissionService's conditional logic into methods.
* sandbox: Document why we set `implicitPartyAllocation` to `false`.
* sandbox: Document why `implicitPartyAllocation` is dangerous.
This doesn’t really make sense since the main point of targetting an older
LF version is because your server does not support the newer LF
version but including dependencies in newer LF versions makes that
completely useless. In the current state, this also produces a bunch
of errors that look very confusing and while we might be able to fix
them, I don’t think it’s worth doing.

* Rework ValueSerializer
- Handle errors directly in the convenience method (it's the only way in which it's used)
- Don't drop the root cause when a serialization error occurs
- Remove outdated comment
CHANGELOG_BEGIN
CHANGELOG_END
* Add alternative with error context for deserialize method
* Make error context evaluated lazily
* Rename inner helper to avoid name clash
This renames methods backing the `ListKnownParties` request to
from `parties`, `getParties` or `listParties` to `listKnownParties`.
CHANGELOG_BEGIN
- [Ledger API Server] Renamed two metrics:
``daml.index.parties`` was renamed to ``daml.index.list_known_parties``
``daml.index.db.get_parties`` was renamed to ``daml.index.db.list_known_parties``
CHANGELOG_END
* sandbox: Add a database test for storing and retrieving parties.
* sandbox: Add database queries for selecting one or many parties.
* ledger-api-test-tool: Add a test for `ListKnownParties`.
* sandbox: Add an endpoint to retrieve a single party's details.
CHANGELOG_BEGIN
- [Ledger API] Added an endpoint to retrieve a single party's details at
``com.digitalasset.ledger.api.v1.admin.PartyManagementService.GetParty``.
Please consult the ledger API reference documentation for more
information.
CHANGELOG_END
* sandbox: Add an endpoint to retrieve a multiple parties' details.
CHANGELOG_BEGIN
- [Ledger API] Added an endpoint to retrieve multiple parties's details at
``com.digitalasset.ledger.api.v1.admin.PartyManagementService.GetParties``.
Please consult the ledger API reference documentation for more

CHANGELOG_END
* sandbox: Getting a single party is a special case of multiple parties.
So let's use that code path and stop duplicating work.
* sandbox: Remove `GetParty`, as it's subsumed by `GetParties`.
"Subsumed" is a great word.
Events in transaction trees should only reference other events
that:
1) are either create or exercise events
2) the requesting parties are a witness of
This applies to recalculated root nodes as well as
the child event ids referenced in exercise nodes.
CHANGELOG_BEGIN
[Sandbox]: fixed projection of transaction trees.
CHANGELOG_END
* Add a warning for data X = Y {..}.
Part of #4718.
changelog_begin
- [DAML Compiler] The DAML compiler now emits a warning when you declare a single-constructor record type where the constructor name does not match the type name, such as ``data X = Y {...}``. This kind of type declaration can cause problems with cross-SDK upgrades because the record constructor name cannot be recorded in the DAML-LF representation. In the future, this warning will be upgraded to an error.

* s/Ctor/Constructor/g
* Deprecate ledger initialization with scenarios
CHANGELOG_BEGIN
[Sandbox] Initializing the sandbox with scenarios is now deprecated in
favor of using DAML Script. The scenario parameter will be removed in
the near future. A warning is logged on startup.
The DAML SDK templates and quickstart guide are using DAML Script.
See the DAML Script migration guide for more information:

The logic for detecting these needs to be improved but for now this at
least gives a useful error message instead of some internal stacktrace.
changelog_begin
changelog_end
On MacOS using Java 13 (at least that was the only combination where
I’ve managed to reproduce this). Sandbox spits out errors of the
following form in ``daml start``
```
java.net.SocketException: Connection reset
```
This appears to be caused by the TCP requests that we send to detect
whether sandbox has started. Switching to using the ``--port-file``
option makes this issue go away.
fixes#4670
changelog_begin
- [DAML Assistant] In certain configurations ``daml start`` produced
a (harmless) ``Connection reset`` log message. This has now been
fixed.

* sandbox-next: Pull runner configuration into the constructor.
No need to do it on `acquire()` if it's pure.
* sandbox-next: Error if a scenario is provided.
Sandbox-Next doesn't support scenarios, instead favoring DAML Script.

* kvutils: On error opening an envelope, throw the correct message.

* ledger-on-sql: On error when querying state, throw the correct error.

changelog_begin
- [DAML Assistant] You can now specify options for
Sandbox/Navigator/the HTTP JSON API in ``daml.yaml`` via
``sandbox-options``/``navigator-options``/``json-api-options``. These
options will be picked up by running ``daml start``. This is
particularly useful for specifying ``--wall-clock-time`` and for
specifying a fixed ledger ID during development.

fixes#2993
* Wrap Script in StateT to make evaluation order a bit less important
This PR wraps the Script newtype in `StateT` which means that
evaluation won’t do much so `debug` behaves a bit more sensibly and
you don’t end up evaluating a script that only consists of `pure` and
`>>=` if you do not execute it.
fixes#4821
changelog_begin
- [DAML Script] Fix an issue where ``debug`` messages were output
before the script was executed.
changelog_end
* Inline StateT and improve error messages
Currently the repl server is bound to 0.0.0.0, which is not great for
security and makes running the tests a bit disruptive on macOS.
This binds it to 127.0.0.1 instead.
CHANGELOG_BEGIN
- [DAML Repl - Experimental] The REPL server will now bind to 127.0.0.1
instead of 0.0.0.0.

* Shift comment and metadata write calls around
Also remove licence line from package.json files

* Broken Windows cache. Unbreak it. NOT FOR MERGING TO MASTER.
* Restore Windows cache; safe now to merge.
The only remaining thing that I wanted to get in before doing that was
overloading ``submit`` which has now happened. I’m sure we can come up
with tons of improvements but I don’t expect breaking changes to the
current state.

- [DAML Script] DAML Script is no longer experimental.

* Track erased types in data-dependencies.
This PR introduces a tracker for Erased types, DA.Generics, and any type, typeclass, or typeclass instance that dependens on them transitively. This is designed to detect and cut out any such definition that will cause problems.
Apologies for the large PR. Originally this was just a small extension to the tracking of old-style typeclasses, but each bugfix uncovered a new bug, and the only way to get it to completely work was to do it all at once. That's why the tracker is so extensive -- the only thing it doesn't track is regular functions, because they will never introduce a cyclic reference to an erased type that gets exposed in the type system (until we implement dependent DAML).
Right now the tracker runs once per data-dependency module, but in a future PR I will make it run once per data-dependency package to reduce the repetitive. This was all tested on a very large DAR, and it runs fine, but it should be much faster once it runs once per package.

* lint

* Add a great test case
Both were previously binding 0.0.0.0, which is inherently insecure. More
importantly to me, that meant running `bazel test //...` essentially
rendered my computer unusable for however long it took (which is
_long_), as it kept popping up focus-stealing dialogs about whether or
not I wanted to trust "java" to open an incoming network connection.
The ScenarioService does not seem to have an existing setup for CLI args
and my Scala-fu is not good enough to add one, so I just changed the
hard-coded path.
The JSON API already had an option, just with the wrong default. This is
technically a breaking change, but I'm hoping to pass it under the
"experimental" flag we still have on the JSON API.
CHANGELOG_BEGIN
- [JSON API - Experimental] As a security improvement, the JSON API
server will now bind on ``127.0.0.1`` by default. Previous behaviour was
to bind on ``0.0.0.0``; you can get that behaviour back by passing in
the (existing) flag ``--address 0.0.0.0``.
- [DAML SDK] The Scenario Service will now bind on ``127.0.0.1``. Previous
behaviour was to bind on ``0.0.0.0``.
