update copyright headers (#12240)
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.

Suport multi-party readAs in triggers (#11299)
* Suport multi-party readAs in triggers

fixes #7640

This does not yet include the trigger service. We’ll tackle that separately.

changelog_begin

- [Daml Triggers] Triggers now support readAs parties. They can be
  specified via `--ledger-readas a,b,c`. As part of this change
  ``testRule`` gained an extra argument to specify the `readAs`
  parties. If you previously used

  ```
  testRule trigger party acsBuilder commandsInFlight s
  ```

  you now need to use

  ```
  testRule trigger party [] acsBuilder commandsInFlight s
  ```

Use DA.Map in triggers if available (#9023)
* Use DA.Map in triggers if available

Replaces DA.Next.Map by DA.Map in the trigger library if the DAML-LF
version supports it, i.e. above 1.11.
Selects on `DAML_GENMAP` and `DAML_GENERIC_COMPARISON` using `CPP`.

changelog_begin
- [Triggers] The trigger library now uses `DA.Map` instead of the
  deprecated `DA.Next.Map` if the targeted Daml-LF version supports it.
  This is a breaking change: Code that interfaced with the triggers
  library using `DA.Next.Map`, e.g. with
  `Daml.Trigger.getCommandsInFlight` or `Daml.Trigger.Assert.testRule`,
  will need to be changed to use `DA.Map` instead.

allow updating user state from high-level trigger rule (#7674)
* allow updating user state from high-level trigger rule

* fix tests and examples for new rule signature

* fix doc for new rule signature

* add changelog

CHANGELOG_BEGIN
- [Triggers] ``rule`` can now ``get`` and ``put`` the user-defined state just
  like ``updateState`` does.  It no longer accepts the state as an argument.
  You can port your rule function types by replacing ``s -> TriggerA`` with
  ``TriggerA s``, removing the last argument from the function, and using
  ``get`` to retrieve the state at the beginning of the ``rule``'s ``do`` block,
  if needed.
  See `issue #7674 <https://github.com/digital-asset/daml/pull/7674>`__.

add Action to high-level trigger updateState (#7621)
* add ActionState to the standard library

* use 1 ActionState, 1 get, 1 put in low-level trigger library

* introduce TriggerStateA for updateState

* fix tests and examples for new updateState signature

CHANGELOG_BEGIN
- [Triggers] The ``updateState`` function now returns a ``TriggerStateA``.  This
  is an action like ``TriggerA``, but doesn't permit emitting commands.  Instead
  of taking the state as an argument and returning a new state, you can
  manipulate the state with ``get``, ``put``, and ``modify``.  Any existing
  ``updateState`` can be ported by replacing ``s -> expr`` in the lambda
  expression with ``-> modify $ \s ->``, and then made to look nicer from there
  as desired.

replace commands-in-flight argument to trigger rule with getCommandsInFlight action (#7600)
* add getCommandsInFlight as a TriggerA action

* immediately update commandsInFlight on emitCommands

- delay until the rule had returned made sense before submitCommands was launched
  immediately; this also makes `getCommandsInFlight` more sensible

* remove commands-in-flight argument from high-level Trigger rule

CHANGELOG_BEGIN
- [Triggers] The "commands in flight" or ``Map CommandId [Command]`` argument has been
  removed from high-level trigger ``rule`` functions; instead, the current
  commands-in-flight can be retrieved with the new ``getCommandsInFlight`` function, which
  can be done immediately at the beginning of the rule's ``do`` block to preserve exact
  existing trigger behavior.
  See `issue #7600 <https://github.com/digital-asset/daml/pull/7600>`__.

introduce new release process (#4513)
Context
=======

After multiple discussions about our current release schedule and
process, we've come to the conclusion that we need to be able to make a
distinction between technical snapshots and marketing releases. In other
words, we need to be able to create a bundle for early adopters to test
without making it an officially-supported version, and without
necessarily implying everyone should go through the trouble of
upgrading. The underlying goal is to have less frequent but more stable
"official" releases.

This PR is a proposal for a new release process designed under the
following constraints:

- Reuse as much as possible of the existing infrastructure, to minimize
  effort but also chances of disruptions.
- Have the ability to create "snapshot"/"nightly"/... releases that are
  not meant for general public consumption, but can still be used by savvy
  users without jumping through too many extra hoops (ideally just
  swapping in a slightly-weirder version string).
- Have the ability to promote an existing snapshot release to "official"
  release status, with as few changes as possible in-between, so we can be
  confident that the official release is what we tested as a prerelease.
- Have as much of the release pipeline shared between the two types of
  releases, to avoid discovering non-transient problems while trying to
  promote a snapshot to an official release.
- Triggerring a release should still be done through a PR, so we can
  keep the same approval process for SOC2 auditability.

The gist of this proposal is to replace the current `VERSION` file with
a `LATEST` file, which would have the following format:

```
ef5d32b7438e481de0235c5538aedab419682388 0.13.53-alpha.20200214.3025.ef5d32b7
```

This file would be maintained with a script to reduce manual labor in
producing the version string. Other than that, the process will be
largely the same, with releases triggered by changes to this `LATEST`
and the release notes files.

Version numbers
===============

Because one of the goals is to reduce the velocity of our published
version numbers, we need a different version scheme for our snapshot
releases. Fortunately, most version schemes have some support for that;
unfortunately, the SDK sits at the intersection of three different
version schemes that have made incompatible choices. Without going into
too much detail:

- Semantic versioning (which we chose as the version format for the SDK
  version number) allows for "prerelease" version numbers as well as
  "metadata"; an example of a complete version string would be
  `1.2.3-nightly.201+server12.43`. The "main" part of the version string
  always has to have 3 numbers separated by dots; the "prerelease"
  (after the `-` but before the `+`) and the "metadata" (after the `+`)
  parts are optional and, if present, must consist of one or more segments
  separated by dots, where a segment can be either a number or an
  alphanumeric string. In terms of ordering, metadata is irrelevant and
  any version with a prerelease string is before the corresponding "main"
  version string alone. Amongst prereleases, segments are compared in
  order with purely numeric ones compared as numbers and mixed ones
  compared lexicographically. So 1.2.3 is more recent than 1.2.3-1,
  which is itself less recent than 1.2.3-2.
- Maven version strings are any number of segments separated by a `.`, a
  `-`, or a transition between a number and a letter. Version strings
  are compared element-wise, with numeric segments being compared as
  numbers. Alphabetic segments are treated specially if they happen to be
  one of a handful of magic words (such as "alpha", "beta" or "snapshot"
  for example) which count as "qualifiers"; a version string with a
  qualifier is "before" its prefix (`1.2.3` is before `1.2.3-alpha.3`,
  which is the same as `1.2.3-alpha3` or `1.2.3-alpha-3`), and there is a
  special ordering amongst qualifiers. Other alphabetic segments are
  compared alphabetically and count as being "after" their prefix
  (`1.2.3-really-final-this-time` counts as being released after `1.2.3`).
- GHC package numbers are comprised of any number of numeric segments
  separated by `.`, plus an optional (though deprecated) alphanumeric
  "version tag" separated by a `-`. I could not find any official
  documentation on ordering for the version tag; numeric segments are
  compared as numbers.
- npm uses semantic versioning so that is covered already.

After much more investigation than I'd care to admit, I have come up
with the following compromise as the least-bad solution. First,
obviously, the version string for stable/marketing versions is going to
be "standard" semver, i.e. major.minor.patch, all numbers, which works,
and sorts as expected, for all three schemes. For snapshot releases, we
shall use the following (semver) format:

```
0.13.53-alpha.20200214.3025.ef5d32b7
```

where the components are, respectively:

- `0.13.53`: the expected version string of the next "stable" release.
- `alpha`: a marker that hopefully scares people enough.
- `20200214`: the date of the release commit, which _MUST_ be on
  master.
- `3025`: the number of commits in master up to the release commit
  (included). Because we have a linear, append-only master branch, this
  uniquely identifies the commit.
- `ef5d32b7ù : the first 8 characters of the release commit sha. This is
  not strictly speaking necessary, but makes it a lot more convenient to
  identify the commit.

The main downsides of this format are:

1. It is not a valid format for GHC packages. We do not publish GHC
  packages from the SDK (so far we have instead opted to release our
  Haskell code as separate packages entirely), so this should not be an
  issue. However, our SDK version currently leaks to `ghc-pkg` as the
  version string for the stdlib (and prim) packages. This PR addresses
  that by tweaking the compiler to remove the offending bits, so `ghc-pkg`
  would see the above version number as `0.13.53.20200214.3025`, which
  should be enough to uniquely identify it. Note that, as far as I could
  find out, this number would never be exposed to users.
2. It is rather long, which I think is good from a human perspective as
  it makes it more scary. However, I have been told that this may be
  long enough to cause issues on Windows by pushing us past the max path
  size limitation of that "OS". I suggest we try it and see what
  happens.

The upsides are:

- It clearly indicates it is an unstable release (`alpha`).
- It clearly indicates how old it is, by including the date.
- To humans, it is immediately obvious which version is "later" even if
  they have the same date, allowing us to release same-day patches if
  needed. (Note: that is, commits that were made on the same day; the
  release date itself is irrelevant here.)
- It contains the git sha so the commit built for that release is
  immediately obvious.
- It sorts correctly under all schemes (modulo the modification for
  GHC).

Alternatives I considered:

- Pander to GHC: 0.13.53-alpha-20200214-3025-ef5d32b7. This format would
  be accepted by all schemes, but will not sort as expected under semantic
  versioning (though Maven will be fine). I have no idea how it will sort
  under GHC.
- Not having any non-numeric component, e.g. `0.13.53.20200214.3025`.
  This is not valid semantic versioning and is therefore rejected by
  npm.
- Not having detailed info: just go with `0.13.53-snapshot`. This is
  what is generally done in the Java world, but we then lose track of what
  version is actually in use and I'm concerned about bug reports. This
  would also not let us publish to the main Maven repo (at least not more
  than once), as artifacts there are supposed to be immutable.
- No having a qualifier: `0.13.53-3025` would be acceptable to all three
  version formats. However, it would not clearly indicate to humans that
  it is not meant as a stable version, and would sort differently under
  semantic versioning (which counts it as a prerelease, i.e. before
  `0.13.53`) than under maven (which counts it as a patch, so after
  `0.13.53`).
- Just counting releases: `0.13.53-alpha.1`, where we just count the
  number of prereleases in-between `0.13.52` and the next. This is
  currently the fallback plan if Windows path length causes issues. It
  would be less convenient to map releases to commits, but it could still
  be done via querying the history of the `LATEST` file.

Release notes
=============

> Note: We have decided not to have release notes for snapshot releases.

Release notes are a bit tricky. Because we want the ability to make
snapshot releases, then later on promote them to stable releases, it
follows that we want to build commits from the past. However, if we
decide post-hoc that a commit is actually a good candidate for a
release, there is no way that commit can have the appropriate release
notes: it cannot know what version number it's getting, and, moreover,
we now track changes in commit messages. And I do not think anyone wants
to go back to the release notes file being a merge bottleneck.

But release notes need to be published to the releases blog upon
releasing a stable version, and the docs website needs to be updated and
include them.

The only sensible solution here is to pick up the release notes as of
the commit that triggers the release. As the docs cron runs
asynchronously, this means walking down the git history to find the
relevant commit.

> Note: We could probably do away with the asynchronicity at this point.
> It was originally included to cover for the possibility of a release
> failing. If we are releasing commits from the past after they have been
> tested, this should not be an issue anymore. If the docs generation were
> part of the synchronous release step, it would have direct access to the
> correct release notes without having to walk down the git history.
>
> However, I think it is more prudent to keep this change as a future step,
> after we're confident the new release scheme does indeed produce much more
> reliable "stable" releases.

New release process
===================

Just like releases are currently controlled mostly by detecting
changes to the `VERSION` file, the new process will be controlled by
detecting changes to the `LATEST` file. The format of that file will
include both the version string and the corresponding SHA.

Upon detecting a change to the `LATEST` file, CI will run the entire
release process, just like it does now with the VERSION file. The main
differences are:

1. Before running the release step, CI will checkout the commit
  specified in the LATEST file. This requires separating the release
  step from the build step, which in my opinion is cleaner anyway.
2. The `//:VERSION` Bazel target is replaced by a repository rule
  that gets the version to build from an environment variable, with a
  default of `0.0.0` to remain consistent with the current `daml-head`
  behaviour.

Some of the manual steps will need to be skipped for a snapshot release.
See amended `release/RELEASE.md` in this commit for details.

The main caveat of this approach is that the official release will be a
different binary from the corresponding snapshot. It will have been
built from the same source, but with a different version string. This is
somewhat mitigated by Bazel caching, meaning any build step that does
not depend on the version string should use the cache and produce
identical results. I do not think this can be avoided when our artifact
includes its own version number.

I must note, though, that while going through the changes required after
removing the `VERSION` file, I have been quite surprised at the sheer number of
things that actually depend on the SDK version number. I believe we should
look into reducing that over time.
