Matt Ellis 992b048dbf Adopt golangci-lint and address issues
We run the same suite of changes that we did on gometalinter. This
ended up catching a few new issues, some of which were addressed and
some of which were baselined.

Tidy up some data structures (#2135)
In preparation for some workspace restructuring, I decided to scratch a
few itches of my own in the code:

* Change project's RuntimeInfo field to just Runtime, to match the
  serialized name in JSON/YAML.

* Eliminate the no-longer-used Context and NoDefaultIgnores fields on
  project, and all of the associated legacy PPC-related code.

* Eliminate the no-longer-used IgnoreFile constant.

* Remove a bunch of "// nolint: lll" annotations, and simply format
  the structures with comments on dedicated lines, to avoid overly
  lengthy lines and lint suppressions.

* Mark Dependencies and InitErrors as `omitempty` in the JSON
  serialization directives for CheckpointV2 files. This was done for
  the YAML directives, but (presumably accidentally) omitted for JSON.

Process deletions conservatively in parallel (#1963)
* Process deletions conservatively in parallel

This commit allows the engine to conservatively delete resources in
parallel when it is sure that it is legal to do so. In the absence of a
true data-flow oriented step scheduler, this approach provides a
significant improvement over the existing serial deletion mechanism.

Instead of processing deletes serially, this commit will partition the
set of condemned resources into sets of resources that are known to be
legally deletable in parallel. The step executor will then execute those
independent lists of steps one-by-one until all steps are complete.

* CR: Make ResourceSet a normal map

* Only use the dependency graph if we can trust it

* Reverse polarity of pendingDeletesAreReplaces

* CR: un-export a few types

* CR: simplify control flow in step generator when scheduling

* CR: parents are dependencies, fix loop index

* CR: Remove ParentOf, add new test for parent dependencies

Move away from ${PROJECT} and ${DESCRIPTION} (#1873)
We generally want examples and apps to be authored such that they are
clonable/deployable as-is without using new/up (and want to
encourage this). That means no longer using the ${PROJECT} and
${DESCRIPTION} replacement strings in Pulumi.yaml and other text files.
Instead, good default project names and descriptions should be specified
in Pulumi.yaml and elsewhere.

We'll use the specified values as defaults when prompting the user, and
then directly serialize/save the values to Pulumi.yaml when configuring
the user's project. This does mean that name in package.json (for nodejs
projects) won't be updated if it isn't using ${PROJECT}, but that's OK.

Our templates in the pulumi/templates repo will still use
${PROJECT}/${DESCRIPTION} for now, to continue to work well with v0.15
of the CLI. After that version is no longer in use, we can update the
templates to no longer use the replacement strings and delete the code
in the CLI that deals with it.

Support project config keys in templates and -c (#1841)
Previously, we only supported config keys that included a ':' delimiter
in config keys specified in the template manifest and in `-c` flags to
`new` and `up`. This prevented the use of project keys in the template
manifest and made it more difficult to pass such keys with `-c`,
effectively preventing the use of `new pulumi.Config()` in project code.

This change fixes this by allowing config keys that don't have a
delimiter in the template manifest and `-c` flags. In such cases, the
project name is automatically prepended behind the scenes, the same as
what `pulumi config set` does.

Initial support for passing URLs to new and up (#1727)
* Initial support for passing URLs to `new` and `up`

This PR adds initial support for `pulumi new` using Git under the covers
to manage Pulumi templates, providing the same experience as before.

You can now also optionally pass a URL to a Git repository, e.g.
`pulumi new [<url>]`, including subdirectories within the repository,
and arbitrary branches, tags, or commits.

The following commands result in the same behavior from the user's
perspective:
 - `pulumi new javascript`
 - `pulumi new https://github.com/pulumi/templates/templates/javascript`
 - `pulumi new https://github.com/pulumi/templates/tree/master/templates/javascript`
 - `pulumi new https://github.com/pulumi/templates/tree/HEAD/templates/javascript`

To specify an arbitrary branch, tag, or commit:
 - `pulumi new https://github.com/pulumi/templates/tree/<branch>/templates/javascript`
 - `pulumi new https://github.com/pulumi/templates/tree/<tag>/templates/javascript`
 - `pulumi new https://github.com/pulumi/templates/tree/<commit>/templates/javascript`

Branches and tags can include '/' separators, and `pulumi` will still
find the right subdirectory.

URLs to Gists are also supported, e.g.:
`pulumi new https://gist.github.com/justinvp/6673959ceb9d2ac5a14c6d536cb871a6`

If the specified subdirectory in the repository does not contain a
`Pulumi.yaml`, it will look for subdirectories within containing
`Pulumi.yaml` files, and prompt the user to choose a template, along the
lines of how `pulumi new` behaves when no template is specified.

The following commands result in the CLI prompting to choose a template:
 - `pulumi new`
 - `pulumi new https://github.com/pulumi/templates/templates`
 - `pulumi new https://github.com/pulumi/templates/tree/master/templates`
 - `pulumi new https://github.com/pulumi/templates/tree/HEAD/templates`

Of course, arbitrary branches, tags, or commits can be specified as well:
 - `pulumi new https://github.com/pulumi/templates/tree/<branch>/templates`
 - `pulumi new https://github.com/pulumi/templates/tree/<tag>/templates`
 - `pulumi new https://github.com/pulumi/templates/tree/<commit>/templates`

This PR also includes initial support for passing URLs to `pulumi up`,
providing a streamlined way to deploy installable cloud applications
with Pulumi, without having to manage source code locally before doing
a deployment.

For example, `pulumi up https://github.com/justinvp/aws` can be used to
deploy a sample AWS app. The stack can be updated with different
versions, e.g.
`pulumi up https://github.com/justinvp/aws/tree/v2 -s <stack-to-update>`

Config values can optionally be passed via command line flags, e.g.
`pulumi up https://github.com/justinvp/aws -c aws:region=us-west-2 -c foo:bar=blah`

Gists can also be used, e.g.
`pulumi up https://gist.github.com/justinvp/62fde0463f243fcb49f5a7222e51bc76`

* Fix panic when hitting ^C from "choose template" prompt

* Add description to templates

When running `pulumi new` without specifying a template, include the template description along with the name in the "choose template" display.

```
$ pulumi new
Please choose a template:
  aws-go                  A minimal AWS Go program
  aws-javascript          A minimal AWS JavaScript program
  aws-python              A minimal AWS Python program
  aws-typescript          A minimal AWS TypeScript program
> go                      A minimal Go program
  hello-aws-javascript    A simple AWS serverless JavaScript program
  javascript              A minimal JavaScript program
  python                  A minimal Python program
  typescript              A minimal TypeScript program
```

* React to changes to the pulumi/templates repo.

We restructured the `pulumi/templates` repo to have all the templates in the root instead of in a `templates` subdirectory, so make the change here to no longer look for templates in `templates`.

This also fixes an issue around using `Depth: 1` that I found while testing this. When a named template is used, we attempt to clone or pull from the `pulumi/templates` repo to `~/.pulumi/templates`. Having it go in this well-known directory allows us to maintain previous behavior around allowing offline use of templates. If we use `Depth: 1` for the initial clone, it will fail when attempting to pull when there are updates to the remote repository. Unfortunately, there's no built-in `--unshallow` support in `go-git` and setting a larger `Depth` doesn't appear to help. There may be a workaround, but for now, if we're cloning the pulumi templates directory to `~/.pulumi/templates`, we won't use `Depth: 1`. For template URLs, we will continue to use `Depth: 1` as we clone those to a temp directory (which gets deleted) that we'll never try to update.

* List available templates in help text

* Address PR Feedback

* Don't show "Installing dependencies" message for `up`

* Fix secrets handling

When prompting for config, if the existing stack value is a secret, keep it a secret and mask the prompt. If the template says it should be secret, make it a secret.

* Fix ${PROJECT} and ${DESCRIPTION} handling for `up`

Templates used with `up` should already have a filled-in project name and description, but if it's a `new`-style template, that has `${PROJECT}` and/or `${DESCRIPTION}`, be helpful and just replace these with better values.

* Fix stack handling

Add a bool `setCurrent` param to `requireStack` to control whether the current stack should be saved in workspace settings. For the `up <url>` case, we don't want to save. Also, split the `up` code into two separate functions: one for the `up <url>` case and another for the normal `up` case where you have workspace in your current directory. While we may be able to combine them back into a single function, right now it's a bit cleaner being separate, even with some small amount of duplication.

* Fix panic due to nil crypter

Lazily get the crypter only if needed inside `promptForConfig`.

* Embellish comment

* Harden isPreconfiguredEmptyStack check

Fix the code to check to make sure the URL specified on the command line matches the URL stored in the `pulumi:template` config value, and that the rest of the config from the stack satisfies the config requirements of the template.

Matt Ellis 645ca2eb56 Allow more types for runtimeOptions

Matt Ellis ce5eaa8343 Support TypeScript in a more first-class way
This change lets us set runtime specific options in Pulumi.yaml, which
will flow as arguments to the language hosts. We then teach the nodejs
host that when the `typescript` is set to `true` that it should load
ts-node before calling into user code. This allows using typescript
natively without an explicit compile step outside of Pulumi.

This works even when a tsconfig.json file is not present in the
application and should provide a nicer inner loop for folks writing
typescript (I'm pretty sure everyone has run into the "but I fixed
that bug!  Why isn't it getting picked up?  Oh, I forgot to run tsc"
problem.

Cache workspaces based on full path. (#1326)
As it stands, we recompute the workspace for the current directory
potentially many times during some CLI operations, most notably
`stack ls`. These changes add a simple cache based on the complete path
passed to `NewFrom`, and eliminate some lagginess in `stack ls` when
there are multiple stacks.

Another option is to calculate the current workspace once in the CLI and
then fetch it as necessary.

Matt Ellis c0b2c4f17f Introduce backend.StackReference
Long term, a stack name alone will not be sufficent to address a
stack. Introduce a new `backend.StackReference` interface that allows

operations.

Matt Ellis bac02f1df1 Remove the need to pulumi init for the local backend
This change removes the need to `pulumi init` when targeting the local
backend. A fair amount of the change lays the foundation that the next
set of changes to stop having `pulumi init` be used for cloud stacks
as well.

Previously, `pulumi init` logically did two things:

1. It created the bookkeeping directory for local stacks, this was
stored in `<repository-root>/.pulumi`, where `<repository-root>` was
the path to what we belived the "root" of your project was. In the
case of git repositories, this was the directory that contained your
`.git` folder.

2. It recorded repository information in
`<repository-root>/.pulumi/repository.json`. This was used by the
cloud backend when computing what project to interact with on
Pulumi.com

The new identity model will remove the need for (2), since we only
need an owner and stack name to fully qualify a stack on
pulumi.com, so it's easy enough to stop creating a folder just for
that.

However, for the local backend, we need to continue to retain some
information about stacks (e.g. checkpoints, history, etc). In
addition, we need to store our workspace settings (which today just
contains the selected stack) somehere.

For state stored by the local backend, we change the URL scheme from
`local://` to `local://<optional-root-path>`. When
`<optional-root-path>` is unset, it defaults to `$HOME`. We create our
`.pulumi` folder in that directory. This is important because stack
names now must be unique within the backend, but we have some tests
using local stacks which use fixed stack names, so each integration
test really wants its own "view" of the world.

For the workspace settings, we introduce a new `workspaces` directory
in `~/.pulumi`. In this folder we write the workspace settings file
for each project. The file name is the name of the project, combined
with the SHA1 of the path of the project file on disk, to ensure that
multiple pulumi programs with the same project name have different
workspace settings.

This does mean that moving a project's location on disk will cause the
CLI to "forget" what the selected stack was, which is unfortunate, but
not the end of the world. If this ends up being a big pain point, we
can certianly try to play games in the future (for example, if we saw
a .git folder in a parent folder, we could store data in there).

With respect to compatibility, we don't attempt to migrate older files
to their newer locations. For long lived stacks managed using the
local backend, we can provide information on where to move things
to. For all stacks (regardless of backend) we'll require the user to
`pulumi stack select` their stack again, but that seems like the
correct trade-off vs writing complicated upgrade code.

Permit plugin versions to float (#1122)
This change lets plugin versions to float in two ways:

1) If a `pulumi plugin install` detects a newer version is available
   already, there's no need to download and install the older version.

2) If the engine attempts to load a plugin at a particular version,
   if a newer version is available, it will be accepted without error.

As part of this, we permit $PATH to have the final say when determining
which version to accept.  That is, it can always override the choice.

Note that I highly suspect, in the limit, that we'll want to stop doing
this for major version incompatibilities. For now, since we don't
envision any such version changes imminently, this will suffice.

Matt Ellis d3240fdc64 Require pulumi login before commands that need a backend
This change does three major things:

1. Removes the ability to be logged into multiple clouds at the same
time. Previously, we supported being logged into multiple clouds at
the same time and the CLI would fan out requests and join responses
when needed. In general, this was only useful for Pulumi employees
that wanted run against multiple copies of the service (say production
and staging) but overall was very confusing (for example in the old
world a stack with the same identity could appear twice (since it was
in two backends) which the CLI didn't handle very well).

2. Stops treating the "local" backend as a special thing, from the
point of view of the CLI. Previouly we'd always connect to the local
backend and merge that data with whatever was in clouds we were
connected to. We had gestures like `--local` in `pulumi stack init`
that meant "use the local mode". Instead, to use the local mode now
you run `pulumi login --cloud-url local://` and then you are logged in
the local backend. Since you can only ever be logged into a single
backend, we can remove the `--local` and `--remote` flags from `pulumi
stack init`, it just now requires you to be logged in and creates a
stack in whatever back end you were logged into. When logging into the
local backend, you are not prompted for an access key.

3. Prompt for login in places where you have to log in, if you are not
already logged in.

Support offline template descriptions (#1044)
Note: This is a minor issue that I didn't get to for M11 that isn't
required for M11 and would be fine merging for post-M11.

When you specify a template name explicitly (e.g.
`pulumi new typescript`), we'll try to download the template tarball
without first downloading the JSON list of available templates. The JSON
includes a description used when replacing the `${DESCRIPTION}` string
in template files. Since we didn't download the JSON, we won't have a
description, so we fallback to a default value (`"A Pulumi project."`).
This also happens when specifying `--offline` to use an existing
template under `~/.pulumi/templates`; we won't have a description for
the template, so we fallback to a default description. The fallback
value happens to be the same as the description for each of our current
templates, so noone will currently notice an issue.

For M11, I included initial support for a template manifest file where
the description (and any future metadata) could be stored, but didn't go
as far as actually reading the file.

This change makes it so the CLI actually reads the description from the
manifest file (if it exists), otherwise falling back to the default
value as is done currently. Some minor related cleanup is included in
this change.

Right now, config.Key is a type alias for tokens.ModuleMember. I did a

looked like the value did not leak to some external process (e.g a
resource provider or a langhost).

Doing this makes it a little clearer (hopefully) where code is
depending on a module member structure (e.g. <package>:config:<value>)
instead of just an opaque type.

Matt Ellis 207a9755d8 Rework configuration model
This change updates our configuration model to make it simpler to
understand by removing some features and changing how things are
persisted in files.

Notable changes:

- We've removed the notion of "workspace" vs "project"
  config. Now, configuration is always stored in a file next to
  `Pulumi.yaml` named `Pulumi.<stack-name>.yaml` (the same file we'd
  use for an other stack specific information we would need to persist
  in the future).
- We've removed the notion of project wide configuration. Every new
  stack gets a completely empty set of configuration and there's no
  way to share common values across stacks, instead the common value
  has to be set on each stack.

We retain some of the old code for the configuration system so we can
support upgrading a project in place. That will happen with the next
change.

This change fixes some issues and allows us to close some
others (since they are no longer possible).

Matt Ellis ed7a4d9157 Check plugin cache first; make version mismatch a warning
Previously, we would prefer a plugin on the $PATH which is more or
less always the case for people hacking on `pulumi`. Later, when we
went to check the loaded plugin version matched the one we requested,
we fail.

Now, if we have a version, we'll first consult the local plugin
cache. If that fails, we'll fall back to the $PATH as we used to.

When we are loading a plugin without a version, we continue to use the
one on the $PATH (without testing the cache) on the assumption it is
newer.

In addition, we've turned the "plugin versions are mis-matched" from
an error into a warning. We expect that we'll only ever see this
warning when something strange is going on (since in the normal case,
we'll have found the exact version in the cache) but having it not
hard fail does help in development cases.

local `.pulumi` directory (e.g. via `git clean`).

The behavior can be disabled by setting the
PULUMI_DISABLE_CHECKPOINT_BACKUPS environment variable, which
we use to disable backups when running all tests other than the
test for this functionality.

This was PR feedback from @justinvp, and ensures we're consistent
with how we retrive the user's home directory elsewhere.

This permits the extension to vary on Windows, e.g. ".exe" vs. ".cmd".

joeduffy 25f5a71568 Add support for project plugins
This adds support for two things:

* Installing all plugins that a project requires with a single command:

    $ pulumi plugin install

* Listing the plugins that this project requires:

    $ pulumi plugin ls --project
    $ pulumi plugin ls -p

joeduffy 932e755305 Move plugins to their own directories
Prior to this change, we had a flat list of files in the
~/.pulumi/plugins directory.  This was simple but unfortunately
too naive, since we in fact have multi-file plugins already.
Dumping them in the same directory increases the risk of a
collision.  Instead, let's put them in their own directories.

This means, for example, you'll see things like

    ~/.pulumi/plugins/
        resource-aws-v0.11.0-dev-8-g57a0d62/
            README.txt
            pulumi-resource-aws

Notice that the binary name stays the same -- e.g., in this
case pulumi-resource-aws -- and does not include the version.
This makes it simple to add it to your $PATH in the usual ways
and have it loaded as a preferred location.

This change introduces logic to skip installing plugins that already
exist, unless --reinstall is explicitly passed to `pulumi plugin install`.

joeduffy c04341edb2 Consult the program for its list of plugins
This change adds a GetRequiredPlugins RPC method to the language
host, enabling us to query it for its list of plugin requirements.
This is language-specific because it requires looking at the set
of dependencies (e.g., package.json files).

It also adds a call up front during any update/preview operation
to compute the set of plugins and require that they are present.
These plugins are populated in the cache and will be used for all
subsequent plugin-related operations during the engine's activity.

We now cache the language plugins, so that we may load them
eagerly too, which we never did previously due to the fact that
we needed to pass the monitor address at load time.  This was a
bit bizarre anyhow, since it's really the Run RPC function that
needs this information.  So, to enable caching and eager loading
-- which we need in order to invoke GetRequiredPlugins -- the
"phone home" monitor RPC address is passed at Run time.

In a subsequent change, we will switch to faulting in the plugins
that are missing -- rather than erroring -- in addition to
supporting the `pulumi plugin install` CLI command.

joeduffy 5d16fc936a Add workspace.GetPluginPath, and use it
This change introduces a workspace.GetPluginPath function that probes
the central workspace cache of plugins for a matching plugin binary that
matches the desired kind, name, and, optionally, version.  It also permits
overriding this with $PATH for developer scenarios.

The analyzer, language, and resource plugin logic now uses this function
for deciding which binary path to load at runtime.

joeduffy c1752d357e Implement basic plugin management
This change implements basic plugin management, but we do not yet
actually use the plugins for anything (that comes next).

Plugins are stored in `~/.pulumi/plugins`, and are expected to be
in the format `pulumi-<KIND>-<NAME>-v<VERSION>[.exe]`.  The KIND is
one of `analyzer`, `language`, or `resource`, the NAME is a hyphen-
delimited name (e.g., `aws` or `foo-bar`), and VERSION is the
plugin's semantic version (e.g., `0.9.11`, `1.3.7-beta.a736cf`, etc).

This commit includes four new CLI commands:

* `pulumi plugin` is the top-level plugin command.  It does nothing
  but show the help text for associated child commands.

* `pulumi plugin install` can be used to install plugins manually.
  If run with no additional arguments, it will compute the set of
  plugins used by the current project, and download them all.  It
  may be run to explicitly download a single plugin, however, by
  invoking it as `pulumi plugin install KIND NAME VERSION`.  For
  example, `pulumi plugin install resource aws v0.9.11`.  By default,
  this command uses the cloud backend in the usual way to perform the
  download, although a separate URL may be given with --cloud-url,
  just like all other commands that interact with our backend service.

* `pulumi plugin ls` lists all plugins currently installed in the
  plugin cache.  It displays some useful statistics, like the size
  of the plugin, when it was installed, when it was last used, and
  so on.  It sorts the display alphabetically by plugin name, and
  for plugins with multiple versions, it shows the newest at the top.
  The command also summarizes how much disk space is currently being
  consumed by the plugin cache.  There are no filtering capabilities yet.

* `pulumi plugin prune` will delete plugins from the cache.  By
  default, when run with no arguments, it will delete everything.
  It may be run with additional arguments, KIND, NAME, and VERSION,
  each one getting more specific about what it will delete.  For
  instance, `pulumi plugin prune resource aws` will delete all AWS
  plugin versions, while `pulumi plugin prune resource aws <0.9`
  will delete all AWS plugins before version 0.9.  Unless --yes is
  passed, the command will confirm the deletion with a count of how
  many plugins will be affected by the command.

We do not yet actually download plugins on demand yet.  That will
come in a subsequent change.

Rename package to project (#935)
This addresses pulumi/pulumi#446: what we used to call "package" is
now called "project".  This has gotten more confusing over time, now
that we're doing real package management.

Also fixes pulumi/pulumi#426, while in here.
