Martin Atkins 549aede792 Remove terraform.ResourceProvider, use providercache.Installer instead
Back when we first introduced provider versioning in Terraform 0.10, we
did the provider version resolution in terraform.NewContext because we
weren't sure yet how exactly our versioning model was going to play out
(whether different versions could be selected per provider configuration,
for example) and because we were building around the limitations of our
existing filesystem-based plugin discovery model.

However, the new installer codepath is new able to do all of the
selections up front during installation, so we don't need such a heavy
inversion of control abstraction to get this done: the command package can
select the exact provider versions and pass their factories directly
to terraform.NewContext as a simple static map.

The result of this commit is that CLI commands other than "init" are now
able to consume the local cache directory and selections produced by the
installation process in "terraform init", passing all of the selected
providers down to the terraform.NewContext function for use in
implementing the main operations.

This commit is just enough to get the providers passing into the
terraform.Context. There's still plenty more to do here, including to
repair all of the tests this change has additionally broken.

James Bardin cd65b28da0 don't call os.NewFile on unknown FDs
os.NewFile was called on file descriptors 3, 4, and 5 during every init,
in case this process happened to be running inside panicwrap. If the
runtime has already chosen one of these file descriptors to use
internally, starting polling on them can cause the runtime to crash.

Initialize the file descriptors lazily, only if we know that they belong
to us, after Wrapped is checked.

Add support for provider metadata to modules. (#22583)
Implement a new provider_meta block in the terraform block of modules, allowing provider-keyed metadata to be communicated from HCL to provider binaries.

Bundled in this change for minimal protocol version bumping is the addition of markdown support for attribute descriptions and the ability to indicate when an attribute is deprecated, so this information can be shown in the schema dump.

addrs: embed Provider in AbsProviderConfig instead of Type
a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings).

The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN. This is fine for now as we are only working with default assumption.

Initial steps towards AbsProviderConfig/LocalProviderConfig separation (#23978)
* Introduce "Local" terminology for non-absolute provider config addresses

In a future change AbsProviderConfig and LocalProviderConfig are going to
become two entirely distinct types, rather than Abs embedding Local as
written here. This naming change is in preparation for that subsequent
work, which will also include introducing a new "ProviderConfig" type
that is an interface that AbsProviderConfig and LocalProviderConfig both
implement.

This is intended to be largely just a naming change to get started, so
we can deal with all of the messy renaming. However, this did also require
a slight change in modeling where the Resource.DefaultProviderConfig
method has become Resource.DefaultProvider returning a Provider address
directly, because this method doesn't have enough information to construct
a true and accurate LocalProviderConfig -- it would need to refer to the
configuration to know what this module is calling the provider it has
selected.

In order to leave a trail to follow for subsequent work, all of the
changes here are intended to ensure that remaining work will become
obvious via compile-time errors when all of the following changes happen:
- The concept of "legacy" provider addresses is removed from the addrs
  package, including removing addrs.NewLegacyProvider and
  addrs.Provider.LegacyString.
- addrs.AbsProviderConfig stops having addrs.LocalProviderConfig embedded
  in it and has an addrs.Provider and a string alias directly instead.
- The provider-schema-handling parts of Terraform core are updated to
  work with addrs.Provider to identify providers, rather than legacy
  strings.

In particular, there are still several codepaths here making legacy
provider address assumptions (in order to limit the scope of this change)
but I've made sure each one is doing something that relies on at least
one of the above changes not having been made yet.

* addrs: ProviderConfig interface

In a (very) few special situations in the main "terraform" package we need
to make runtime decisions about whether a provider config is absolute
or local.

We currently do that by exploiting the fact that AbsProviderConfig has
LocalProviderConfig nested inside of it and so in the local case we can
just ignore the wrapping AbsProviderConfig and use the embedded value.

In a future change we'll be moving away from that embedding and making
these two types distinct in order to represent that mapping between them
requires consulting a lookup table in the configuration, and so here we
introduce a new interface type ProviderConfig that can represent either
AbsProviderConfig or LocalProviderConfig decided dynamically at runtime.

This also includes the Config.ResolveAbsProviderAddr method that will
eventually be responsible for that local-to-absolute translation, so
that callers with access to the configuration can normalize to an
addrs.AbsProviderConfig given a non-nil addrs.ProviderConfig. That's
currently unused because existing callers are still relying on the
simplistic structural transform, but we'll switch them over in a later
commit.

* rename LocalType to LocalName

Martin Atkins 97d64581c6 helper/logging: Loosen the filtering heuristic even more
Now we'll consider any message that doesn't start with a digit as a
continuation. This is _definitely_ in loose, best-effort territory now
since a continuation line could very well start with a digit, but
ultimately this is still better than the totally broken behavior that
preceded it.

Just to make sure that none of these heuristics interfere with producing
complete, accurate logs for TRACE, we'll skip the LevelFilter altogether
in that case.

Martin Atkins faffb3a784 helper/logging: Warn about levels other than TRACE
The filtering for other log levels is unreliable and glitchy because it's
trying to infer information from the log stream that isn't reliably
represented.

Although the previous commit has improved the situation somewhat, it is
still a tricky and unreliable heuristic, so worth a warning to anyone who
is reading such a log that if they see something confusing it could be
a result of the heuristic not working fully.
2019-12-05 15:22:03 -08:00
Martin Atkins 30bf83cdeb helper/logging: Bring the LevelFilter into our own codebase
In order to make this work reasonably we can't avoid using some funny
heuristics, which are somewhat reasonable to apply within the context of
Terraform itself but would not be good to add to the general "logutils".

Specifically, this is adding the additional heuristic that lines starting
with spaces are continuation lines and so should inherit the log level
of the most recent non-continuation line.

providers: use addrs.Provider as map keys for provider.Factory (#23548)
* terraform/context: use new addrs.Provider as map key in provider factories
* added NewLegacyProviderType and LegacyString funcs to make it explicit that these are temporary placeholders

This PR introduces a new concept, provider fully-qualified name (FQN), encapsulated by the `addrs.Provider` struct.

James Bardin 49439d02d1 sanitize provisioner output strings
The grpc protocol requires strings to be valid utf8, but because
provisioners often don't have control over the command output, invalid
utf8 sequences can make it into the response causing grpc transport
errors.

Replace all invalid utf sequences with the standard utf replacement
character in the provisioner output. The code is a direct copy from the
go1.13 std library, and can be replaced with strings.ToValidUTF8 once
it's available.

Martin Atkins 39e609d5fd vendor: switch to HCL 2.0 in the HCL repository
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.

This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.

For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.

Fix 2 specific panics in the sdk when reading nil or computed maps from
various configurations. The legacy sdk code is too dependent on undefined
behavior to attempt to find and fix the root cause at this point.

Since the code is essentially frozen for future development, these
changes are specifically targeted to only prevent panics from within
providers.  Because any code effected by these changes would have
panicked, there cannot be anything depending on the behavior, and these
should be safe to fix.

James Bardin 4dcda04d96 prevent an empty string from being lost
The helper/schema diff process loses empty strings, causing them to show
up as unset (null) during apply. Besides failing to show as set by
GetOk, the absence of the value also triggers the schema to insert a
default value again during apply.

It would also be be preferable if the defaults weren't re-evaluated
again during ApplyResourceChange, but that would require a more invasive
patch to the field readers, and ensuring the empty string is stored in
the plan should block the default.
