Add eager timeouts to the polling functions used in daml start and assistant integration tests. (#12361)
* Add timeouts to polling funcs in daml start.

This PR adds timeouts to some polling functions used in daml start and
the assistant integration tests, and also early exits based on a process
exit status. E.g. waitForHttpServer will make sure some process is
still running, instead of waiting to timeout.

The effect of this is that now whenever there is some error in a
subprocess, daml start and the integration tests will finish early
instead of running forever (or timing out in bazel).

Split daml-lf encode/decode Haskell libraries (#11906)
* Split daml-lf encode/decode Haskell libraries

I was working on limiting the supported input versions in damlc. This
requires the list of stable package ids so we can allow those to be
decoded even if they are older.

However that leads to a cyclical dependency:
To get the package ids of the stable packages, I need to encode
them. The version check is in the decoder. If those live in the same
package, I now end up with a cyclical dependency and
Bazel (understandably) gets very sad.

This PR splits decoding/encoding into two libraries with the
generation of stable packages only depending on encoding.

* Fix RoundingMode deprecation warnings

* JavaX annotation dependency

* javax.xml.bind was removed in Java 11

* JDK 11 no longer has a separate JRE tree

* Remove unused jdk_nix import

* remove now redundant jdk11_nix

* Java 8 --> 9 increased Instant.now() precision

See https://bugs.openjdk.java.net/browse/JDK-8068730

The precision of `Instant.now()` increased between Java 8 and Java 9.
On Linux and MacOS this doesn't seem to be a problem, as the precision
still seems to be at micro seconds. However, on Windows this now causes
errors of the following form:
```
java.lang.IllegalArgumentException: Conversion of Instant
2021-11-05T13:58:56.726875100Z to microsecond granularity would result
in loss of precision.
```
Suggesting that it now offers sub-microsecond precision.

`TimestampConversion.instantToMicros` had a check to fail if the
conversion lead to a loss of precision. In the specific failing test
case this is not a concern, so this adds a `roundInstantToMicros`
variant that avoids this kind of error.

Fix closure references in Daml Repl (#8950)
* Fix closure references in Daml Repl

Turns out the comment "we probably need to extend this to merge the
modules from each line" was exactly correct: If the result evaluates
to a closure (or a value including a closure), it can reference
definitions from the current module. This happens if the simplifier
lifted something out of the current definition (otherwise we have only
one and it cannot be recursive so no chance of leaking a reference).

This PR fixes this by checking whether the result references the
current module and if it does, we keep it around.

Disable deriving-defaults per file (#8684)
Disabling it per target works nicely for compilation but it gets
annoying in ghci since the warnings are still triggered. We could
disable it everywhere but I think the warning is generally useful. I
tried patching proto3-suite to use DerivingStrategies but that doesn’t
work because haskell-src is dead and doesn’t support it. So for now
adding it to the per-file list seems like the best option.

Port damlc dependencies to Scala 2.13 (#8423)
* Port damlc dependencies to Scala 2.13

I got a bit fed up by the fact that going directory by directory
didn’t really work since there are two many interdependencies in
tests (e.g., client tests depend on sandbox, sandbox tests depend on
clients, engine tests depend on DARs which depend on damlc, …).

So before attempting to continue with the per-directory process, this
is a bruteforce approach to break a lot of those cycles by porting all
dependencies of damlc which includes client bindings (for DAML Script)
and Sandbox Classic (also for DAML Script).

If this is too annoying to review let me know and I’ll try to split it
up into a few chunks.

Cache computation of top-level values at definition level (#7818)
* Cache computation of top-level values at definition level

Earlier the computation of a top-level value was only cached at the
use-site in SEVal. This introduces SDefinition which contains the same
mechanism as SEVal to cache the computation.

As expected this does not impact performance much:

before: CollectAuthority.bench  //daml-lf/scenario-interpreter/CollectAuthority.dar  CollectAuthority:test  avgt   40  44.267 ± 0.728  ms/op
after: CollectAuthority.bench  //daml-lf/scenario-interpreter/CollectAuthority.dar  CollectAuthority:test  avgt   40  43.693 ± 0.702  ms/op

What this does have a significant impact is on reducing the number of distinct
SValues for things like type class dictionaries etc, so that now we have one
SValue per dictionary rather than one per SEVal.

Fix trace statement handling in DAML Script service (#7292)
* Fix trace statement handling in DAML Script service

This PR makes sure that we get both trace statements coming from the
ledger client as well as from the ledger server. In the script service
those are two different Speedy machines so we need to interleave
them. This is a bit messy so let me explain the steps (apologies for
not splitting it up but I think it’s easier to understand the
motivation when it is a single PR):

1. Abstract over the tracelog interface. The ringbuffer doesn’t makes
   sense for our purposes and is annoying to clear.

2. Pass in the respective fields of `Machine` to `Conversions` instead
   of the whole machine. This is both a simpler design (passing around
   mutable objects scares me) and it allows us to assemble the fields
   from different machines.

3. Initialize the ledger machine with a simple ArrayBuffer tracelog.

4. After `submit` and `submitMustFail` copy the tracelog from the
   ledger to the client.

`--noincompatible_windows_native_test_wrapper` this no longer works on
Windows since `.sh` files are not directly executable on Windows.

This change fixes the issue by producing the script file in a dedicated
rule and then wrapping it in a `sh_test` rule which also works on
Windows.

Print results in DAML REPL and support pure expressions (#6799)
* Print results in DAML REPL and support pure expressions

This extends DAML REPL to behave similar to GHCi in that it prints
results if the result is an instance of `Show` and it also supports
pure, non-script expressions now. We copy the same hack from GHCi and
typecheck multiple times. This doesn’t seem to have any noticeable
performance impact (which makes sense, the expressions are tiny and
the overhead of grpc is much much bigger).

Docs and tests are updated.

Revert ANF changes and add a testcase for evaluation order (#6645)
* Revert ANF changes and add a testcase for evaluation order

After careful consideration, we decided that the change in evaluation
order that was accidentally introduced by the ANF changes should be
considered a breaking change or arguably even a bug and should not
land in 1.3.0.

Therefore, this PR reverts the following commits:

1. 353d0da6f7
2. a45b51042f
3. 04c7b2af7f
4. a624dd7242
5. b3aab72cee

Other PRs mostly had trivial merge conflicts that I resolved. The two
most interesting ones here are probably

1. https://github.com/digital-asset/daml/pull/6576 which was easy to
   resolve and the change to return SEValue instead of SExpr is still
   nice and useful even if we do not need the guarantees.
2. it https://github.com/digital-asset/daml/pull/6542 which required
   some changes since the constructors changed. If you want to review
   those changes in detail (they are pretty straightforward so not too
   important), it’s probably easiest to check out this PR and run
   ```
   git diff 2cd2a8f2a8
   daml-lf/interpreter/src/main/scala/com/digitalasset/daml/lf/speedy/Compiler.scala
   ```
   to see the diff to the parent commit of the first commit that
   introduced ANF.

Speedy ANF (#6440)
* ANF transformation in Speedy.

The idea behind this PR is to transform speedy expressions into a simpler form where all non-atomic sub-expressions are made explicit by the introduction of let-forms. In particular, for the function-application form. These simpler forms allow the execution engine to take advantage of the atomic assumption, and often removes many additional execution steps. In particular the pushing of continuations to allow execution to continue after a compound expression has been reduced to a value.

Support multiple auth tokens in DAML Script (#6473)
* Support multiple auth tokens in DAML Script

This piggy backs on top of the already existing --participant-config
feature. While you can argue that it might be slightly confusing that
you have to specify the same participant twice to specify different
auth tokens, I think this actually makes sense: In an ideal
world (ignoring any performance issues) you have one participant per
party anyway and one connection per participant specified in the
config file still seems like a very reasonable model.

changelog_begin

- [DAML Script] You can now use DAML Script with multiple auth
  tokens. This is particularly useful if you are working with the JSON
  API where you can only have one party per token or with an IAM that
  only provides single-party tokens. The tokens are specified in the
  participant configuration passed via `--participant-config` in a new
  ``access_token`` field. The existing `--acess-token-file` flag is still supported if you want to use the same token for all connections. See
  https://docs.daml.com/daml-script/index.html#running-daml-script-against-authenticated-ledgers
  for more details.

Integrate time service into DAML Script (#6417)
This integrates the time service into DAML script thereby covering the
main piece of scenarios that was missing from DAML script.

This PR does two things (they are very related and doing them together
makes it much easier to test):

1. It “fixes” `getTime` to return the ledger time in static mode by
   querying the ledger time service instead of defaulting to the Unix
   epoch which is pretty useless and I would consider the old behavior
   a bug. We keep the old behavior via the JSON API since there is no
   time service.

2. It adds `setTime` to set the ledger time via the time service. This
   is only supported in static time mode (sadbonx and other ledgers do
   not expose the time service in wallclock mode because changing time
   makes it not wallclock) or via the JSON API (no time service).

fixes #6220

changelog_begin

- [DAML Script] DAML Script’s `getTime` now correctly handles time
  changes in static time mode and returns the current time by querying
  the time service rather than defaulting to the Unix epoch. Note that
  when run via the JSON API, it still returns the Unix epoch.

- [DAML Script] Add `setTime` to DAML Script which sets the ledger
  time via the ledger API time service. Note that this is only
  supported when running over gRPC in static time mode.
