Load specific provider versions if requested (#2648)
* Load specific provider versions if requested

As part of pulumi/pulumi#2389, we need the ability for language hosts to
tell the engine that a particular resource registration, read, or invoke
needs to use a particular version of a resource provider. This was not
previously possible before; the engine prior to this commit loaded
plugins from a default provider map, which was inferred for every
resource provider based on the contents of a user's package.json, and
was itself prone to bugs.

This PR adds the engine support needed for language hosts to request a
particular version of a provider. If this occurs, the source evaluator
specifically records the intent to load a provider with a given version
and produces a "default" provider registration that requests exactly
that version. This allows the source evaluator to produce multiple
default providers for a signle package, which was previously not
possible.

This is accomplished by having the source evaluator deal in the
"ProviderRequest" type, which is a tuple of version and package. A
request to load a provider whose version matches the package of a
previously loaded provider will re-use the existing default provider. If
the version was not previously loaded, a new default provider is
injected.

Alex Clemmer fac6944781 Warn instead of error when refresh'd resource is unhealthy
Fixes #2633.

Currently when a user runs `refresh` and a resource is in a state of
error, the `refresh` will fail and the resource state will not be
persisted. This can make it vastly harder to incrementally fix
infrastructure. The issue mentioned above explains more of the
historical context, as well as some specific failure modes.

This commit resolves this issue by causing refresh to *not* report an
error in this case, and instead to simply log a warning that the
`refresh` has recognized that the resource is in an unhealthy state
during state sync.

James Nugent edab10e9c8 Use Go Modules for dependency tracking
This commit switches from dep to Go 1.12 modules for tracking Pulumi
dependencies. Rather than _building_ using Go modules, we instead use the `go
mod vendor` command to populate a vendor tree in the same way as `dep ensure`
was previously doing.

In order to prevent checksum mismatches, it was necessary to also update CI to
use Go 1.12 instead of 1.11 - which also necessitated fixing some linting errors
which appeared with the upgraded golangci-lint for 1.12.

Install missing plugins on startup (#2560)
* Install missing plugins on startup

This commit addresses the problem of missing plugins by scanning the
snapshot and language host on startup for the list of required plugins
and, if there are any plugins that are required but not installed,
installs them. The mechanism by which plugins are installed is exactly
the same as 'pulumi plugin install'.

The installation of missing plugins is best-effort and, if it fails,
will not fail the update.

This commit addresses pulumi/pulumi-azure#200, where users using Pulumi
in CI often found themselves missing plugins.

Refresh inputs (#2531)
These changes take advantage of the newly-added support for returning
inputs from Read to update a resource's inputs as part of a refresh.
As a consequence, the Pulumi engine will now properly detect drift
between the actual state of a resource and the desired state described
by the program and generate appropriate update or replace steps.

As part of these changes, a resource's old inputs are now passed to the
provider when performing a refresh. The provider can take advantage of
this to maintain the accuracy of any additional data or metadata in the
resource's inputs that may need to be updated during the refresh.

This is required for the complete implementation of
https://github.com/pulumi/pulumi-terraform/pull/349. Without access to
the old inputs for a resource, TF-based providers would lose all
information about default population during a refresh.

Better log messages for replaces/changes (#2452)
We previously logged the number of replaces and changes returned from a call to Diff, but not the actual properties that were forcing replace.  Several times we've had to debug issues with unexpected replaces being proposed, and this information is very useful to have access to.

Add support for explicit delete-before-replace (#2415)

Use "discard" when deleting read resources (#2280)
In general, a "delete" in Pulumi is destroying an actual physical
resource. In the case of a read resource, however, the delete is
merely removing the resource from the stack; the physical resource
is not affected. These changes attempt to clarify this situation by
using the term "discard" rather than "delete".

Pat Gavlin 1ecdc83a33 Implement more precise delete-before-replace semantics. (#2369)
This implements the new algorithm for deciding which resources must be
deleted due to a delete-before-replace operation.

We need to compute the set of resources that may be replaced by a
change to the resource under consideration. We do this by taking the
complete set of transitive dependents on the resource under
consideration and removing any resources that would not be replaced by
changes to their dependencies. We determine whether or not a resource
may be replaced by substituting unknowns for input properties that may
change due to deletion of the resources their value depends on and
calling the resource provider's Diff method.

This is perhaps clearer when described by example. Consider the
following dependency graph:

  A
__|__
B   C
|  _|_
D  E F

In this graph, all of B, C, D, E, and F transitively depend on A. It may
be the case, however, that changes to the specific properties of any of
those resources R that would occur if a resource on the path to A were
deleted and recreated may not cause R to be replaced. For example, the
edge from B to A may be a simple dependsOn edge such that a change to
B does not actually influence any of B's input properties. In that case,
neither B nor D would need to be deleted before A could be deleted.

In order to make the above algorithm a reality, the resource monitor
interface has been updated to include a map that associates an input
property key with the list of resources that input property depends on.
Older clients of the resource monitor will leave this map empty, in
which case all input properties will be treated as depending on all
dependencies of the resource. This is probably overly conservative, but
it is less conservative than what we currently implement, and is
certainly correct.

Pat Gavlin cfe4e127be
Add API types for the V3 checkpoint (#2384)
Resources gain two new fields: `PropertyDependencies` and
`PendingReplacement`. The former maps an input property's name to the
dependencies that may affect the value of that property. The latter is
used to track resources that have been deleted as part of a
delete-before-replace operation but have not yet been recreated.

In addition to the new fields, resource properties may now contain
encrypted first-class secret values. These values are of type `SecretV1`,
where the `Sig` field is set to `resource.SecretSig`.

Finally, the deployment type gains a new field, `SecretsProviders`,
which contains any configuration necessary to handle secrets that may be
present in resource properties.

Matt Ellis a02bfb6469 Include symlink'd regular files in directory archives
When constructing an Archive based off a directory path, we would
ignore any symlinks that we saw while walking the file system
collecting files to include in the archive.

A user reported an issue where they were unable to use the
[sharp](https://www.npmjs.com/package/sharp) library from NPM with a
lambda deployed via Pulumi. The problem was that the library includes
native components, and these native components include a bunch of
`*.so` files. As is common, there's a regular file with a name like
`foo.so.1.2.3` and then symlinks to that file with the names
`foo.so.1.2`, `foo.so.1` and `foo.so`. Consumers of these SOs will
try to load the shorter names, i.e. `foo.so` and expect the symlink to
resolve to the actual library.

When these links are not present, upstack code fails to load.

This changes modifies our logic such that if we have a symlink and it
points to a regular file, we include it in the archive. At this time,
we don't try to add it to the archive as a symlink, instead we just
add it as another copy of the regular file. We could explore trying to
include these things as symlinks in archive formats that allow
them (While zip does support this, I'm less sure doing this for zip
files will be a great idea, given the set of tricks we already play to
ensure our zip files are usable across many cloud vendors serverless
offerings, it feels like throwing symlinks into the mix may end up
causing even more downstream weirdness).

We continue to ignore symlinks which point at directories. In
practice, these seem fairly uncommon and doing so lets us not worry
about trying to deal with ensuring we don't end up chasing our tail in
cases where there are circular references.

While this change is in pulumi/pulumi, the downstream resource
providers will need to update their vendored dependencies in order to
pick this up and have it work end to end.

Close plugin context on plan creation failure (#2304)

Handle unconfigured plugins in Diff. (#2238)
After #2088, we began calling `Diff` on providers that are not configured
due to unknown configuration values. This hit an assertion intended to
detect exactly this scenario, which was previously unexpected.

These changes adjust `Diff` to indicate that a Diff is unavailable and
return an error message that describes why. The step generator then
interprets the diff as indicating a normal update and issues the error
message to the diagnostic stream.

Fixes #2223.

Matt Ellis 72d52c6e1f Don't fail on configuration keys like a:config:b:c
Configuration keys are simple namespace/name pairs, delimited by
":". For compatability, we also allow
"<namespace>:config:<name>", but we always record the "nice" name in
`Pulumi.<stack-name>.yaml`.

While `pulumi config` and friends would block setting a key like
`a🅱️c` (where the "name" has a colon in it), it would allow
`a:config:b:c`. However, this would be recorded as `a🅱️c` in
`Pulumi.<stack-name>.yaml`, which meant we'd error when parsing the
configuration file later.

To work around this, disallow ":" in the "name" part of a
configuration key.  With this change the following all work:

```
keyName
my-project:keyName
my-project:config:keyName
```

However, both

`my-project:keyName:subKey`
`my-project:config:keyName:subKey`

are now disallowed.

I considered allowing colons in subkeys, but I think it adds more
confusion (due to the interaction with how we allow you elide the
project name in the default case) than is worthwhile at this point.

Add an API for importing stack outputs (#2180)
These changes add a new resource to the Pulumi SDK,
`pulumi.StackReference`, that represents a reference to another stack.
This resource has an output property, `outputs`, that contains the
complete set of outputs for the referenced stack. The Pulumi account
performing the deployment that creates a `StackReference`  must have
access to the referenced stack or the call will fail.

This resource is implemented by a builtin provider managed by the engine.
This provider will be used for any custom resources and invokes inside
the `pulumi:pulumi` module. Currently this provider supports only the
`pulumi:pulumi:StackReference` resource.

Tidy up some data structures (#2135)
In preparation for some workspace restructuring, I decided to scratch a

* 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.

Go 1.10 made some breaking changes to the headers in archive/tar [1] and

tests passing with both, wherever a hardcoded hash is expect we switch
on `runtime.Version()` to select whether we want the Go 1.9 (currently

Eventually these switches should be removed in favour of using the later
version only, so they are liberally commented to explain the reasoning.

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

This commit allows the engine to conservatively delete resources in

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.

joeduffy 3468393490 Make a smattering of CLI UX improvements
Since I was digging around over the weekend after the change to move
away from light black, and the impact it had on less important
information showing more prominently than it used to, I took a step
back and did a deeper tidying up of things. Another side goal of this
exercise was to be a little more respectful of terminal width; when
we could say things with fewer words, I did so.

* Stylize the preview/update summary differently, so that it stands
  out as a section. Also highlight the total changes with bold -- it
  turns out this has a similar effect to the bright white colorization,
  just without the negative effects on e.g. white terminals.

* Eliminate some verbosity in the phrasing of change summaries.

* Make all heading sections stylized consistently. This includes
  the color (bright magenta) and the vertical spacing (always a newline
  separating headings). We were previously inconsistent on this (e.g.,
  outputs were under "---outputs---"). Now   the headings are:
  Previewing (etc), Diagnostics, Outputs, Resources, Duration, and Permalink.

* Fix an issue where we'd parent things to "global" until the stack
  object later showed up. Now we'll simply mock up a stack resource.

* Don't show messages like "no change" or "unchanged". Prior to the
  light black removal, these faded into the background of the terminal.
  Now they just clutter up the display. Similar to the elision of "*"
  for OpSames in a prior commit, just leave these out. Now anything
  that's written is actually a meaningful status for the user to note.

* Don't show the "3 info messages," etc. summaries in the Info column
  while an update is ongoing. Instead, just show the latest line. This
  is more respectful of width -- I often find that the important
  messages scroll off the right of my screen before this change.

    For discussion:

        - I actually wonder if we should eliminate the summary
          altogether and always just show the latest line. Or even
          blank it out. The summary feels better suited for the
          Diagnostics section, and the Status concisely tells us
          how a resource's update ended up (failed, succeeded, etc).

        - Similarly, I question the idea of showing only the "worst"
          message. I'd vote for always showing the latest, and again
          leaving it to the Status column for concisely telling the
          user about the final state a resource ended up in.

* Stop prepending "info: " to every stdout/stderr message. It adds
  no value, clutters up the display, and worsens horizontal usage.

* Lessen the verbosity of update headline messages, so we now instead
  of e.g. "Previewing update of stack 'x':", we just say
  "Previewing update (x):".

* Eliminate vertical whitespace in the Diagnostics section. Every
  independent console.out previously was separated by an entire newline,
  which made the section look cluttered to my eyes. These are just
  streams of logs, there's no reason for the extra newlines.

* Colorize the resource headers in the Diagnostic section light blue.

Note that this will change various test baselines, which I will
update next. I didn't want those in the same commit.

joeduffy be9ead855d Eliminate the same prefix
Recently, we eliminated bright black text, which IMHO makes the
"same" lines really stand out more than we want them to. This is
partly just due to the heavyweight nature of the "*" character,
which we precede every line with. This has the effect of making it
toughter to scan the update to see what's going to happen. The goal
of SpecUnimportant (bright black) was that we wanted to draw less
attention to certain elements of the CLI text -- and have them fade
into the background (apparently it was too successful at this ;-))

So, this change eliminates the "*" prefix for same operations
altogether. It reads better to my eyes and keeps the original intent.

Retire pending deletions at start of plan (#1886)
* Retire pending deletions at start of plan

Instead of letting pending deletions pile up to be retired at the end of
a plan, this commit eagerly disposes of any pending deletions that were
pending at the end of the previous plan. This is a nice usability win
and also reclaims an invariant that at most one resource with a given
URN is live and at most one is pending deletion at any point in time.

* Rebase against master

* Fix a test issue arising from shared snapshots

* CR feedback

* plan -> replacement

* Use ephemeral statuses to communicate deletions

Fix provider cancellation. (#1914)
We signal provider cancellation by hangning a goroutine off of the plan
executor's parent context. To ensure clean shutdown, this goroutine also
listens on a channel that closes once the plan has finished executing.
Unfortunately, we were closing this channel too early, and the close was
racing with the cancellation signal. These changes ensure that the
channel closes after the plan has fully completed.

Fixes #1906.
Fixes pulumi/pulumi-kubernetes#185.

Validate type tokens before using them (#1904)
* Validate type tokens before using them

When registering or reading a resource, we take the type token given to
us from the language host and assume that it's valid, which resulted in
assertion failures in various places in the engine. This commit
validates the format of type tokens given to us from the language host
and issues an appropriate error if it's not valid.

Along the way, this commit also improves the way that fatal exceptions
are rendered in the Node language host.

* Pre-allocate an exception for ReadResource

* Fix integration test

* CR Feedback

This commit is a lower-impact change that fixes the bugs associated with
invalid types on component resources and only checks that a type is
valid on custom resources.

* CR Take 2: Fix up IsProviderType instead of fixing call sites

* Please gometalinter
