* Properly fill eventId for active contracts
This gets rid of the last remaining bit that assumes
contractId==eventId.
Fixes#65.
Contributes to #2068.
* Do not conflate eventId and contractId in the daml-lf interpreter
* Do not treat contractId as eventId in Ledger.scala
* Remember the transaction that divulged a contract.
* In this scope we can treat divulged contracts the same as disclosed ones
* revert a few more syntactical changes to make the overall diff smaller
* retain the same behavior on the scenario service api
* fix unreleased after rebase
* Generalize AnyTemplate type to Any in DAML-LF
See #3131 for the motivation for this. The tl;dr is that we need
something like AnyTemplate for choice types as well.
Since the protobuf was already more general in anticipation of such a
change, this change only changes the internal AST on the Haskell and
Scala side.
Since AnyTemplate change has never made it out of 1.dev, I updated the
changelog in the LF spec instead of adding a new entry.

On one of our huge DAML code bases this has brought down the size of the
DALF by 60% and cut the memory usage during decoding by 50%.

interning actually works.

* Add Any type and to_any/from_any primitives to protobuf
Following a suggestion by Rémy, the protobuf representation is more
general and is associated with an arbitrary type instead of a
typecon. This allows us to easily extend this later to a full Any
type.
I’ve still called the type in the protobuf Any instead of Haskell’s
Dynamic since I find AnyTemplate more clear than DynamicTemplate and
having AnyTemplate and Dynamic seems confusing.
Right now, the decoder enforces that the type is a TypeCon.

* Implement AnyTemplate DAML-LF type on the Scala side
This is the first part of
https://github.com/digital-asset/daml/issues/2876. The PR adds
AnyTemplate to Speedy and to the internal expression representation
and adapts all the relevant infrastructure (e.g., the typechecker) and
the tests.
It does not yet change the protobuf representation, the Haskell side
or the spec. I’ll update the spec together with changing the protobuf.
* Add comments to SBToAnyTemplate and SBFromAnyTemplate
* Address some comments from Remy
* Only allocate TBuiltin(BTAnyTemplate) once
* Preload packages to engine during upload
* Improve logging in KeyValueCommitting and add timing information
* Fix scenario service tests now that logging is done in interpreter
This is a first step towards DAML triggers. At the moment, triggers
can consume (very simplified) create and archive events via the Ledger
API, update a state based on that and emit log mesages at each update.
All of this is likely to change significantly in the future, so I
would prefer to not focus too much on minor details for now.
As a test, I added a simple trigger that tracks active contract ids.
* Add a method to initialize speedy from a non-update expression
We need something like this for DAML triggers. You can kind of fake it
since all the individual fields of Machine are exposed but `initial`
is private (for good reasons as it sets ctrl to null) which makes this
rather annoying to do.
* Base other initialization methods on fromSExpr
* add Numeric.java
* ledger-api: rename `decimal` field to `numeric` in value protobuf
* Address Gerolf's comment

* Initial version for configuration submissions and authorization

* Cleanup test output and comments
* kvutils test-suite
- Add unit tests for kvutils
- Thread the input state into Commit monad
- Fix a bug in handling rejected transactions (from previous refactoring)
* Address PR review
- Add submissionId to configuration changes.
- Revert the dedup of the ParticipantNotAuthorized message. This did not buy much
and we need to duplicate it anyway when modularizing kvutils.
Currently, the `SExpr` class has a method `apply`, which is basically an
alias for `SEApp`. Using this method makes the code harder to read, at
least of me. After all, ASTs are _data_ and not _control_. Thus, having
a DSL for them seems a bit overkill.

* daml-lf: implement internal Numeric type

* Address Gerolf's comments
in particular add tests for round and toLong
* Make stack traces work with cached top level values
For stack traces to work properly in the presence of cached top level values,
we need to cache the stack trace together with the value and restore the
stack trace when we get the value from the cache.
We also need to push location information under the monadic. Otherwise, the
location information will be removed from the continuation stack before the
monadic action is _executed_.
We also change one test case to use `fail` instead of `error` since `fail` is
more tricky than `error` (due to the lazy expression embedding in DAML-LF).
Unfortunately, the test did not work woth `fail` in the past because of the
issues fixed in this PR.
* Explain special cases when pushing location information
* Show function names in stack trace on failing scenario
So far, we've only shown the location of the function but not its name.
Now, we add the name of the function as well.
* daml-lf: make match2's fallback lazy, and add tuple2 syntax for better inference

* lf-value-json: don't copy

* lf-value-json: round decimals rather than rejecting, in either string or number form
* lf-value-json: support output to JsNumber for int64s and decimals, separately
- not dependent on JavaScript safe integer range, because that is not
the purpose of this option
* lf-value-json: uncomment some now-tested rounding cases
* allow None record fields to be omitted in object syntax
* release notes
* Print stack traces in the scenario on failure
Currently, we only print the last source location, which is not
particularly helpful for debugging. Now, we put all source locations we
encounter during execution on the continuation stack and print them when
a scenario fails. This PR does not print the names of entered functions
or choices. We leave this for a future PR.

daml-lf-archive-java is put together from the proto sources with the

was dependent on the output of $(locations :daml_lf_proto_lib_java),

The new logic filters by name rather than position.

* Allow shadowing of type variables in DAML and DAML-LF
We relax the DAML-LF type checker to allow for shadowing of type variables.
This does not need big changes since the substitution we use already avoids
name capture. The test for alpha equivalence converts to de Bruijn indices
on the fly and is hence not a problem either.
We inline type synonyms during the conversion from GHC Core to DAML-LF. This
requires alpha renaming. The cheapest way to get this, is to use the unique
names of type variables instead of their surface names.
This fixes#1915.

* Update rules_haskell and static GHC
Remove patches that have been upstreamed or are no longer required.
Update still required patches to match the new rules_haskell version.
Previously we patched rules_haskell to coerce GHC into using static
Haskell libraries in most places. In particular we moved hs-libraries
entries into extra-libraries entries in the package configuration files.
A much cleaner approach is to compile GHC with a static RTS, then GHC
will by itself choose to load static Haskell libraries.
* Remove haskell_cc_import
* da-hs-daml-cli -> daml-cli
* da-hs-damlc-app -> damlc-app
* Introduce contract key to exercise node
Track the contract key in NodeExercises. This is in
preparation for adding the key into exercise events, and
for support for contract keys in kvutils, where we need
to be able to compute the outputs of the submission, e.g.
the contract key that would be unset by a consuming exercise.
This introduces transaction version 8.
* Move release note on contract keys in exercises to unreleased.rst
* Address Stephen's review
- Drop changelog entry for this change as it is not user facing
- Add info on version 8 to transaction.rst. Fix typo in version 7.
- Reorder VersionTimeline as per review

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`.

* 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
This is a preparation for making the actors in DAML-LF's exercise
instruction optional (see #1347).
This is technically a breaking change but since `exerciseExplicit` has never
been exposed via the documentation, we don't add a release note.

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
* Fix package valdiation for DAML-LF 1.4
Currently, complex contract keys are are not accepted for DAML-LF 1.4
although they should because we forgot to roll the version when freezing
DAML-LF 1.4.
@bitonic we need a way forward to avoid this in the future.
* Fix test
* Format Scala
* Add more tests for (un)serializable contract ids
I want to lift this restriction in a subsequent PR for the next version
of DAML-LF. Let's first make sure we have a correct implementation for the
current version though.
* fix test
* in serializability tests, check the modules are properly typed
The foldWithPathState is a fold over the transaction that allows
keeping extra state along the path of the traversal.
We add computePerPartyProjectionRoots in preparation for the
work on privacy-aware kvutils, where transaction nodes are stored
separately rather than in one blob. This function allows us to compute
the projected transaction roots for each party mentioned in the
transaction. We require this information to establish the order
of the root nodes when the size and form of the transaction is
blinded by assigning random node ids.

* 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 up the scenario error messages
Up to now, the engine blindly assumed that contract ids pointed to
contracts of the right type. However, this assumption is faulty:
contract ids coming from the Ledger API cannot be type checked
in command translation since we need access to the contract itself
to do so.
This caused some seriously surprising / broken behavior: one could
send an exercise command with the wrong template id and still go
through, or break internal invariants about the type of choices.
This commit fixes this by checking that the type of the contract
instances we fetch is correct at runtime.

Also move Interface and InterfaceType out of the reader subpackage; they
belong with the rest of the data model at the iface root.
The specific mechanics of reading a Dar all the way to producing an
EnvironmentInterface are left to Scala codegen's Codegen and Java
codegen's CodeGenRunner; there's no consensus or great stability on the
best way to tie these pieces together, but all the pieces might as well
be available in the interface library at least.
Inspired by a query on Slack by @leonelag regarding reading the
codegen-relevant parts of dalfs and dars; thanks!

Add field 'usedPackages' to Transaction to record the packages
that were used during interpretation to produce said transaction.
This serves as a hint to specify what packages are required to
validate the transaction. Note that this may not be sufficient
for future implementations that e.g. compile DAML-LF to JVM
bytecode and require packages containing only type definitions
as inputs.
This hint is mainly required for ledger implementations for which the
packages are tracked similarly to contract instances, and which
require that all inputs to their transaction must be declared
beforehand.
This work is required for the participant-state key-value utilities
described in issue #410 and implemented in PR #637.

Enforcing non empty list of input files
The DAML-LF Archive Protobuf definitions, as packaged and distributed
via Bintray and the SDK, currently packages the files in a directory
structure that does not match with the actual one, causing the usage of
`protoc` on the packaged definitions to raise errors. This commit fixes
it by packaging the files in the same directory structure as the one
found in the repository.
* fix various conversion functions from string to Decimal
Fixes#399.
This fixes a critical bug -- since:
* The DAML-LF spec specifies that the scale of `Decimal` is 10 --
that is, there are at most 10 digits past the decimal point:
<79bbf5c794/daml-lf/spec/value.rst (field-decimal)>.
* However, the code converting from the string representation that
we get on the wire was _not_ performing this check. This is due
to two reasons:
- `Decimal.check` is a function that checks whether a given
`Decimal` is within the upper and lower bounds of what the
DAML-LF spec specifies, but crucially it does _not_ check that
the scale is not exceeded:
<79bbf5c794/daml-lf/data/src/main/scala/com/digitalasset/daml/lf/data/Decimal.scala (L31)>.
This behavior is correct in some cases (more on that later),
but not in others. Crucially, `Decimal.fromString`, which was
supposed to check if a decimal string literal is valid, used
this function, which means that it accepted string literals
containing numbers out of the required scale, rounding them to
make them fit within the scale. This function has been renamed
to `Decimal.checkWithinBoundsAndRound`, and a new function
`Decimal.checkWithinBoundsAndWithinScale` has been added, which
fails if the number provided has data not within the scale.
`Decimal.fromString` now uses
`Decimal.checkWithinBoundsAndWithinScale`.
- `ApiToLfEngine.parseDecimal` assumed that `Decimal.fromString` _did_
fail when passed numbers that were in any way invalid, and
moreover did _not_ use the result of `Decimal.fromString`, but rather
re-parsed the string into an unconstrained `BigDecimal`:
<79bbf5c794/ledger/ledger-api-common/src/main/scala/com/digitalasset/platform/participant/util/ApiToLfEngine.scala (L96)>.
The reason for the code to work this way is that in the past
it was responsible for converting decimal strings both for the
current engine but also for an older version of the engine which
handled decimals of a different type. Both issues have been fixed.
* Therefore, `Decimal`s with scale exceeding the specified scale
made it into the engine, and contracts could be created containing
this invalid value.
* Once on the ledger, these bad numbers can be used to produce extremely
surprising results, due to how `Decimal` operations are
implemented. Generally speaking, all operations on `Decimal`
first compute the result and then run the output through
`Decimal.checkWithinBoundsAndRound`. The reason for this behavior
is that we specify multiplication and division as rounding their
output. Consider the case where the bad value 0.00000000005 made
it to the engine, and is then added to 100. The full-precision
result will be 100.00000000005, which after rounding becomes 100.
Therefore, on a ledger where such invalid values exist, it is not
the case that `y > 0 ==> x + y != x`, and so on.
Thanks a bunch to @briandbecker for the excellent bug report.
* fix failing test using to much precision
* Add buildifier targets.

* 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.
