* language: upgrades independent of stdlib
This fixes several issues in the code generation from dalfs. As a result
we can now generate upgrades independent of the stdlib source.
* Support reading of DAML-LF 1.5 in damlc again
We dropped support for this for no good reason when we dropped support for
writing DAML-LF 1.5. Being able to _read_ older versions of DAML-LF is
important for the upgrading story.
We don't support reading older versions of DAML-LF since there seems to
be no need for this.
* Fix integration test
Previously we rewrote references to `PRSelf` to `PRImport` references
every time we call `initWorld`. However, we call `initWorld` quite
often (e.g. every time we run a scenario) while the packages that need
to be rewritten stay constant. Since rewriting the package references
requires traversing the whole package, this can be quite expensive.
This PR moves the rewriting of package references out of `initWorld`
and caches it as part of `GeneratePackageMap`.
On a large project where I tested this, this caused a drop in the
runtime of `daml test` from 250s to 200s. In the IDE this can also
make a pretty big difference since we call this everytime we run a
scenario which we do on every file change.

My primary goal is to avoid confusion when starting to support DAML-LF's
enum types. I also think these types were never particularly useful,
although I introduced them myself...
I find the current names very confusing and unintuitive.
I'm aware that there are other primitives called `TO_TEXT_X`. But there the
`X` is meant to be a type index to `TO_TEXT`. This doesn't make much sense in
the context of `TO_TEXT_CODE_POINTS` though since there's no type named
`CodePoints`.
This was scary to do when we still had all the `Tagged` stuff around. Since
that stuff is gone, let's add the instances and make pretty print anything
DAML-LF related more uniform.
* Drop support for DAML-LF 1.3 from damlc
This means `damlc` now only supports versions allowing arbitrary expressions
as contract keys. This is very helpful for the upcoming new template
de/re-sugaring underpinning generic templates.
* Unpin a few DAML-LF target versions in tests
* Fix golden tests
* Adapt changelog to rebase
* Rename DAML-LF scenario tests to 1.dev
* Update tests to --target 1.dev
* Fix release notes
* Back parseInt/parseDecimal by DAML-LF primitives when available
DAML-LF 1.5 introduces two new primitives `FROM_TEXT_INT64` and
`FROM_TEXT_DECIMAL`. We translate `parseInt` and `parseDecimal` to
these primitives when compiling to DAML-LF 1.5 or later.
This fixes#1398.
* Fix DAML-LF decoder (Scala)
* Freeze DAML-LF 1.dev into DAML-LF 1.5
In other words, we release DAML-LF 1.5.
This is required for generic templates (#1387).
* description of FROM_TEXT_INT64 & FROM_TEXT_DECIMAL
* amend version history
add ``FROM_TEXT_INT64`` and ``FROM_TEXT_DECIMAL`` in the specification changelog
* typos
* Fix markup in DAML-LF spec
* Add release notes
* Drop support for DAML-LF 1.1 from damlc
Part of #853.
* Fix docs test
* Add show party test back
* Update release notes
* Remove target version from Java codegen test
* Make the actors optional in DAML-LF's exercise instruction
If they are not present, the controllers will be filled in. Surface DAML
does this currenty anyway by fetching the contract and computing the
choice controllers before each `exercise`. This change will allow for
getting rid of the additional `fetch` preceding each `exercise`.
The compiler does not use the new form yet. I will do this in a separate
PR together with tests for the new behaviour.
This fixes#1347.
* Fix DAML-LF type checker test
* Check presence of actors for old DAML-LF versions in decoder
* Lift restriction on serializable contract ids in DAML-LF 1.dev
In DAML-LF 1.dev, make `ContractId a` serializable whenever `a` is
serializable. This is part 2 of #1277.
* Reformat Scala
* Add changelog entry to daml_lf_1.proto
* Replace all occurrences of Tagged in DAML-LF AST with newtypes
This must end as it makes the code bases harder to understand without
adding any benefits.
* Add two more usages of mkVal
* Remove Orphans.Lib_hashable
* Remove tagged from package dependencies
* Derive stock classes as such
* Relax syntactic restriction on contract keys in DAML-LF 1.dev
We lift the syntactic restriction that contact keys must be built using
only record constructions and projections entirely when compiling to
DAML-LF 1.dev. To make this more useful, we also search all sub-expressions
of `maintainer` in `key` during our rewriting of `maintainer` for using
`this` to using `key`.
As one of our next steps we should bring `key` into scope in `maintainer`
and perhaps deprecate the use of `this` at some point in the future.
* Fix versioning
* Adapt package validation to complext contract keys
The current naming suggests, the protobuf encoding and the CLI use different
textual representations of minor versions, which is not true. They only
differ in their types. We push this type conversion to the call sites
of both functions instead.
Currently, we test the default and the newest DAML-LF version. After the
recent introduction of 1.dev, this doesn't make sense anymore. Instead, we
now test the default version (which should always be the newest version)
and the dev version.

* make the governance rule about dev more direct
* 1.x
* missed plural; thanks @leo-da
* further definition of 1.dev in LFv1 spec; thanks @remyhaemmerle-da
* Drop DAML-LF 1.0 support from compiler
This will enable us to add `Functor`, `Applicative` and `Monad` instances
for `(->) r` in the `daml-stdlib`. We'll do this in a separate PR.
* Remove codegen test for DAML-LF 1.0
* Make all Text tests be qualified to Scenario

- `reserved` cannot occur within `oneof` block
* remove --allow-dev test
* dev removal release note followed the previous release; move it back to HEAD
* Stop using Template Haskell to derive type class instances
Template Haskell is notorious for causing slow build times. That's why we
remove the `makeInstances*` family of functions and use proper `deriving`
clauses instead.
* Make hlint happy
* Make hlint even more happy
* Derive Data
* Remove ToJSON instances from DAML-LF AST
* Clean up how we check DAML-LF feature support in damlc
Currently, we have a predicate that tells us whether a DAML-LF version
supports a specific feature. We replace this by a data type which captures
the name of a feature and the minimal DAML-LF version which supports it.
* Rename featureDisjunctionChoices into featureFlexibleControllers
* Error only once
Co-Authored-By: hurryabit <martin.huschenbett@posteo.me>
Add a check to the Haskell implementation of the DAML-LF type checker to
make sure that the current DAML-LF version supports contract keys when they
are encountered.
* Add buildifier targets.
The tool allows to check and format BUILD files in the repo.
To check if files are well formatted, run:
bazel run //:buildifier
To fix badly-formatted files run:
bazel run //:buildifier-fix
* Cleanup dade-copyright-headers formatting.
* Fix dade-copyright-headers on files with just the copyright.
* Run buildifier automatically on CI via 'fmt.sh'.
* Reformat all BUILD files with buildifier.
Excludes autogenerated Bazel files.
* Add location information to DAML-LF produced by damlc
This is required to get error locations in the scenario view. Rigth now,
the location information for `create`/`exercise` still points to the
template/choice. I'll fix that in a separate PR.
* Fix test expectations
* Fix more tests
* Do not divulge contracts to observers in nonconsuming exercises
Disables support for non-default ledger feature flags, as they
are meaningless since ledger server logic does not respect the flags.
Instead of large refactoring to add support for the old flag settings,
it is best to disallow the deprecated flags, and later on phase out the
flags completely.
Re-enables test_divulgence_of_token in sandbox semantic tests.
Fixes#157.
* purge LedgerFlags entirely...
...since we only support one version of them anyway, and clearing them
* updated release notes
This was used by the old DAML-LF based record constructor/projection
inliner. We'bve recently replaced by an inlining mechanism which is part
of the conversion from GHC Core to DAML-LF.
