With this change, Daml exerciseByKey use the LF primitive
ExerciseByKey instead of the combinason of FetchByKey + Exercise.

CHANGELOG_END
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.
CHANGELOG_BEGIN
CHANGELOG_END
* Add proper error handling for missing contract keys
These are clearly not internal errors so we should not be calling
`crash` here. Canton in fact already started string matching on the
crash message which is definitely not what we want.

This fixes a bug in the Speedy interpreter. With this change, the
interpreter crashes if it attempts to fetch using a contract key that
has an empty set of maintainers. This propagates to exerciseByKey as
this command is compiled using fetchByKey speedy built-in.
This is a breaking change approved by @bame-da .
CHANGELOG_BEGIN
[LF] (Bug fix) enforce non-empty maintainers in contract key during fetchByKey and exericiseByKey.
CHANGELOG_END
This fixes a bug in the Speedy interpreter. With this change, the
interpreter crashes if it attempts to create a contract containing a
contract key that has an empty set of maintainers.
This is a breaking change approved by Bernhard Elsner.
CHANGELOG_BEGIN
- [LF] (Bug fix) enforce non-empty maintainers in contract key during
contract creation.
CHANGELOG_END
Currently, a call to `create` for a template with a contract key
evaluates the key even before _executing_ the `create`, which is _way_
too early. See #5967 for examples what this implies.
This change moves the evaluation of the key into the execution of the
`create` and therein _after_ the evaluation of the `ensure` clauses,
which is where it belongs according to the DAML-LF specification.
Unfortunately, the specification does not say anything about the
relative evaluation order of the `agreement`, `signatory`, `observer`
and `key` clauses. Thus, I've deciced to evaluate the key after the
other three, which seems to be its natural place given its optionality.
This fixes#5967.
CHANGELOG_BEGIN
CHANGELOG_END
Add keys with maintainers to Fetch nodes
The new field is populated by the interpreter whenever the fetched
contract has a key. Used for contract key reinterpretation in Canton.
CHANGELOG_BEGIN
- [DAML-LF] Add keys with maintainers to Fetch nodes in transactions.
CHANGELOG_END
* Added a partition function to prelude.
* Fixed partition function documentation.
* CHANGELOG_BEGIN
- Added `partition` function to prelude.
CHANGELOG_END
* Fixed partition documentation.
