Martin Atkins ce68b4d27c config: Remove legacy interpolation function implementations
These are often confusing for new contributors, since this looks
suspiciously like the right place to add new functions or change the
behavior of existing ones.

To reduce that confusion, here we remove them entirely from this package
(which is now dead code in Terraform 0.12 anyway) and include in the
documentation comments a pointer to the current function implementations.

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.

Ensure matching modules with metadata when requested (#21640)
When a constraint is defined including build metadata, go-version ignores
this, and if a user explicitly requests a build version, this will now return that version.
Also covers cases when a user adds build metadata to a non-equality constraint,
or in a constraint with multiple conditions (ex. >0.8.0+abc, <1.0.0), and gives
and error when this occurs.

Martin Atkins 88e76fa9ef configs/configschema: Introduce the NestingGroup mode for blocks
In study of existing providers we've found a pattern we werent previously
accounting for of using a nested block type to represent a group of
arguments that relate to a particular feature that is always enabled but
where it improves configuration readability to group all of its settings
together in a nested block.

The existing NestingSingle was not a good fit for this because it is
designed under the assumption that the presence or absence of the block
has some significance in enabling or disabling the relevant feature, and
so for these always-active cases we'd generate a misleading plan where
the settings for the feature appear totally absent, rather than showing
the default values that will be selected.

NestingGroup is, therefore, a slight variation of NestingSingle where
presence vs. absence of the block is not distinguishable (it's never null)
and instead its contents are treated as unset when the block is absent.
This then in turn causes any default values associated with the nested
arguments to be honored and displayed in the plan whenever the block is
not explicitly configured.

The current SDK cannot activate this mode, but that's okay because its
"legacy type system" opt-out flag allows it to force a block to be
processed in this way anyway. We're adding this now so that we can
introduce the feature in a future SDK without causing a breaking change
to the protocol, since the set of possible block nesting modes is not
extensible.

James Bardin 97bde5467c filter nulls when shimming a config
Nulls can't exist in HCL, and the legacy sdk will panic when
encountering them. The map shim already did this, just copy the same
pattern in the list case.

James Bardin bb62aba651 add (forces new resource) to provider test diffs
Add the (forces new resource) annotation to the diff output for provider
tests failures when we can. This helps providers narrow down what might
be triggering changes when encountering test failures with the new SDK.

Martin Atkins 995042666a config/hcl2shim: ValuesSDKEquivalent float64 comparison of numbers
The SDK uses only the native int and float64 types internally for values
that are specified as being "number" in schema, so for SDK purposes only
a float64 level of precision is significant.

To avoid any weirdness introduced as we shim and un-shim numbers, we'll
reduce floating point numbers to float64 precision before comparing them
to try to mimic the result the SDK itself would've gotten from comparing
its own float64 versions of these values using the Go "==" operator.

Martin Atkins 6b03c81375 config/hcl2shim: ValuesSDKEquivalent function
This is a first pass of an "approximately equal" function that tries to
mimic the reduced precision caused by the field reader abstraction in
helper/schema so that we can distinguish between meaningful changes to
the proposed new state and incidental ones that just result from the loss
of precision in the SDK implementation.

James Bardin c7269bec02 Revert "insert empty objects into config from empty blocks"
This reverts commit 3677522a28.
Later changes negate the need for this, and removing these again
prevents us from having to strip them back out when helper/schema
doesn't want them.

James Bardin f3c80b4765 add zero values to sets with a flatmap count of 1
If a flatmap value has a count of 1 and no other attributes, it usually
indicates the equivalent configuration of an empty (or default value)
set block. Treat this as containing a single zero value object and
insert that into the set.

James Bardin 3677522a28 insert empty objects into config from empty blocks
When creating a legacy config from a cty.Value, empty nested blocks
should corespond to empty objects in the config.

James Bardin 6fee1f24ab don't add duplicate unknowns to a set
The flatmap shim was lazily adding duplicate items and letting cty.Set
clear them out, but if those duplicates contains unknown values they
can't be checked for equality and will end up remaining in the set.

James Bardin f959b560a2 trim index steps from RequiresNew paths

Martin Atkins 93630cf95f config/hcl2shim: ConfigValueFromHCL2Block function
This is a more specialized version of ConfigValueFromHCL2 which is
specifically for config values that represent the content of a block
body in the configuration.

By using the schema of that block we can more precisely emulate the old
HCL1/HIL behaviors by distinguishing attributes from blocks and applying
some slightly different behaviors for the handling of null values and
of empty collections that are representing the absense of blocks of a
particular type.

James Bardin f4416ee1df update the new RequiresReplace function
Make the function work specifically how we need for RequiresReplace.
Skip index changes, any set changes are only recorded as the set itself,
and filter out duplicate paths.

Add a few more tests to check for various nested structures.
2018-10-16 18:53:51 -07:00
James Bardin 30ff37f335 change PathFromFlatmapKey to RequiresReplace
Rather than try and make a generalized path function here, what we
really need in a function to generate the paths needed for
RequiresReplace. This needs to take into account that sets elements
don't need to be indexed themselves, and changes to collection index
values aren't needed.
2018-10-16 18:53:51 -07:00
James Bardin 44e993ec29 add hcl2shim.PathFromFlatmapKey
PathFromFlatmapKey is used to convert a flatmap key to a cty.Path, and
ensures it conforms to the type schema.

This is used when handling Diffs, where the ResourceAttrDiffs are
indexed by the flatmapped key values, and we need to convert those to
addresses to apply to a cty.Value.

James Bardin 05e85885f9 handle Null collections in flatmaps
When creating a flatmap from a cty.Value, there may be Null collections
which don't need to be added to the flatmap at all. Skip over these to
avoid panicking in ElementIterator with a Null value.

James Bardin c28ce02f2a return a nil flatmap when presented with a NullVal
A nil flatmap will be encoded as a NullVal of the correct type. When
Converting a NullVal back to a flatmap, return nil immediately rather
than attempting to build the values.
2018-10-16 18:50:29 -07:00
James Bardin ac8ee20233 return a NullVal when presented with a nil flatmap

Martin Atkins 479c6b2466 move "configschema" from "config" to "configs"
The "config" package is no longer used and will be removed as part
of the 0.12 release cleanup. Since configschema is part of the
"new world" of configuration modelling, it makes more sense for
it to live as a subdirectory of the newer "configs" package.

Martin Atkins 299fe25a04 hcl2shim: Handle unknown values when shimming to/from flatmap
Previously unknown values were round-tripping through flatmap and coming
out as known strings containing the UnknownVariableValue. (The classic bug
that, ironically, was one of the big reasons to write cty!)

Now we properly handle unknown values in both directions: going in to
flatmap we write UnknownVariableValue at the appropriate key (as the count
for sequences or maps) and then coming out of flatmap we turn
UnknownVariableValue back into a cty unknown value of the requested type.

Martin Atkins ccc1b6990f config/hcl2shim: shims from flatmap to cty and vice-versa
These particular shims will have a pretty limited lifetime in mainline
Terraform code (primarily to stub out the new expression evaluator against
the old state structs until the new format is implemented) but will live
on for some time in state migration and provider plugin compatibility
shims.

Martin Atkins ebafa51723 command: Various updates for the new backend package API
This is a rather-messy, complex change to get the "command" package
building again against the new backend API that was updated for
the new configuration loader.

A lot of this is mechanical rewriting to the new API, but
meta_config.go and meta_backend.go in particular saw some major
changes to interface with the new loader APIs and to deal with
the change in order of steps in the backend API.

Martin Atkins 22d140e883 configschema: Block.CoerceValue method
The usual way to use a configschema.Block is to obtain a hcldec spec from
it and then decode an hcl.Body. There are inevitably situations though
where a body has already been decoded into a cty.Value before we know
which schema we need to use.

This new method CoerceValue is intended to deal with this case, applying
the schema to an already-decoded value in what should be an intuitive way
for most situations.

Martin Atkins c51d22bdeb config/hcl2shim: don't put nils in ConfigValue maps
Absent values are omitted by the old code we are emulating in HCL, so we
