We no longer need to support 0.12-and-earlier-style provider addresses
because users should've upgraded their existing configurations and states
on Terraform 0.13 already.
For now this is only checked in the "init" command, because various test
shims are still relying on the idea of legacy providers the core layer.
However, rejecting these during init is sufficient grounds to avoid
supporting legacy provider addresses in the new dependency lock file
format, and thus sets the stage for a more severe removal of legacy
provider support in a later commit.
The tmp directory path is longer on Macs than other systems and was wrapping
across lines when printed, breaking the string match in the test.
Fix suggested by @apparentlymart is to add two spaces before the leading
'-' when printing to prevent the diagnostic renderer wrapping the line.
As we add and remove support for different target platforms over time,
there will be transition periods where the available platforms for
each provider will be different than the available platforms for Terraform
CLI itself.
In recognition of that possibility, here we add a more specialized error
message for that situation which tries to explain the problem a little
more clearly than the generic error message that came before it.
In an ideal world we'd be able to detect situations where a newer or older
version has support in a similar vein to what we do with provider protocol
incompatibilities, but we don't currently have logic to fetch the data
necessary to implement that, so this is instead a presentation-only change
aimed at allowing some possible near-future changes to the supported
target platforms.
In earlier commits we started to make the installation codepath
context-aware so that it could be canceled in the event of a SIGINT, but
we didn't complete wiring that through the API of the getproviders
package.
Here we make the getproviders.Source interface methods, along with some
other functions that can make network requests, take a context.Context
argument and act appropriately if that context is cancelled.
The main providercache.Installer.EnsureProviderVersions method now also
has some context-awareness so that it can abort its work early if its
context reports any sort of error. That avoids waiting for the process
to wind through all of the remaining iterations of the various loops,
logging each request failure separately, and instead returns just
a single aggregate "canceled" error.
We can then set things up in the "terraform init" and
"terraform providers mirror" commands so that the context will be
cancelled if we get an interrupt signal, allowing provider installation
to abort early while still atomically completing any local-side effects
that may have started.
We only preserve these major upgrade versions for one major version after
they are added, because our upgrade path assumes moving forward only one
major version at a time. Now that our main branch is tracking towards
Terraform 0.14, we no longer need the 0.13upgrade subcommand.
This also includes some minor adjustments to the 0.12upgrade command to
align the terminology used in the output of both commands. We usually
use the word "deprecated" to mean that something is still available but
no longer recommended, but neither of these commands is actually available
so "removed" is clearer.
We could in principle have removed even the removal notice for 0.12upgrade
here, but it's relatively little code and not a big deal to keep around
to help prompt those who might try to upgrade directly from 0.11 to 0.14.
We may still remove the historical configuration upgrade commands prior to
releasing Terraform 1.0, though.

In Terraform 0.11 and earlier, the "terraform fmt" command was very
opinionated in the interests of consistency. While that remains its goal,
for pragmatic reasons Terraform 0.12 significantly reduced the number
of formatting behaviors in the fmt command. We've held off on introducing
0.12-and-later-flavored cleanups out of concern it would make it harder
to maintain modules that are cross-compatible with both Terraform 0.11
and 0.12, but with this aimed to land in 0.14 -- two major releases
later -- our new goal is to help those who find older Terraform language
examples learn about the more modern idiom.
More rules may follow later, now that the implementation is set up to
allow modifications to tokens as well as modifications to whitespace, but
for this initial pass the command will now apply the following formatting
conventions:
- 0.11-style quoted variable type constraints will be replaced with their
0.12 syntax equivalents. For example, "string" becomes just string.
(This change quiets a deprecation warning.)
- Collection type constraints that don't specify an element type will
be rewritten to specify the "any" element type explicitly, so
list becomes list(any).
- Arguments whose expressions consist of a quoted string template with
only a single interpolation sequence inside will be "unwrapped" to be
the naked expression instead, which is functionally equivalent.
(This change quiets a deprecation warning.)
- Block labels are given in quotes.
Two of the rules above are coming from a secondary motivation of
continuing down the deprecation path for two existing warnings, so authors
can have two active deprecation warnings quieted automatically by
"terraform fmt", without the need to run any third-party tools.
All of these rules match with current documented idiom as shown in the
Terraform documentation, so anyone who follows the documented style should
see no changes as a result of this. Those who have adopted other local
style will see their configuration files rewritten to the standard
Terraform style, but it should not make any changes that affect the
functionality of the configuration.
There are some further similar rewriting rules that could be added in
future, such as removing 0.11-style quotes around various keyword or
static reference arguments, but this initial pass focused only on some
rules that have been proven out in the third-party tool
terraform-clean-syntax, from which much of this commit is a direct port.
For now this doesn't attempt to re-introduce any rules about vertical
whitespace, even though the 0.11 "terraform fmt" would previously apply
such changes. We'll be more cautious about those because the results of
those rules in Terraform 0.11 were often sub-optimal and so we'd prefer
to re-introduce those with some care to the implications for those who
may be using vertical formatting differences for some semantic purpose,
like grouping together related arguments.
Previously we were just using hclwrite.Format, a token-only formatting
pass. Now we'll do that via the full hclwrite parser, getting the
formatting as a side-effect of the parsing and re-serialization.
This should have no change in observable behavior as-is, but in a future
commit we'll add some additional processing rules that modify the syntax
tree before re-serializing it.
Previously formatting was just a simple wrapper around hclwrite.Format.
That remains true here, but the call is factored out into a separate
method in preparation for making it also do some Terraform-specific
cleanups in a future commit.
The logic for what constitutes a valid hash and how different hash schemes
are represented was starting to get sprawled over many different files and
packages.
Consistently with other cases where we've used named types to gather the
definition of a particular string into a single place and have the Go
compiler help us use it properly, this introduces both getproviders.Hash
representing a hash value and getproviders.HashScheme representing the
idea of a particular hash scheme.
Most of this changeset is updating existing uses of primitive strings to
uses of getproviders.Hash. The new type definitions are in
internal/getproviders/hash.go.
* Add creation test and simplify in-place test
* Add deletion test
* Start adding marking from state
Start storing paths that should be marked
when pulled out of state. Implements deep
copy for attr paths. This commit also includes some
comment noise from investigations, and fixing the diff test
* Fix apply stripping marks
* Expand diff tests
* Basic apply test
* Update comments on equality checks to clarify current understanding
* Add JSON serialization for sensitive paths
We need to serialize a slice of cty.Path values to be used to re-mark
the sensitive values of a resource instance when loading the state file.
Paths consist of a list of steps, each of which may be either getting an
attribute value by name, or indexing into a collection by string or
number.
To serialize these without building a complex parser for a compact
string form, we render a nested array of small objects, like so:
[
[
{ type: "get_attr", value: "foo" },
{ type: "index", value: { "type": "number", "value": 2 } }
]
]
The above example is equivalent to a path `foo[2]`.
* Format diffs with map types
Comparisons need unmarked values to operate on,
so create unmarked values for those operations. Additionally,
change diff to cover map types
* Remove debugging printing
* Fix bug with marking non-sensitive values
When pulling a sensitive value from state,
we were previously using those marks to remark
the planned new value, but that new value
might *not* be sensitive, so let's not do that
* Fix apply test
Apply was not passing the second state
through to the third pass at apply
* Consistency in checking for length of paths vs inspecting into value
* In apply, don't mark with before paths
* AttrPaths test coverage for DeepCopy
* Revert format changes
Reverts format changes in format/diff for this
branch so those changes can be discussed on a separate PR
* Refactor name of AttrPaths to AttrSensitivePaths
* Rename AttributePaths/attributePaths for naming consistency

Despite not requiring the configuration for any other reason, the taint
subcommand should not execute if the required_version constraints cannot
be met. Doing so can result in an undesirable state file upgrade.
The providers schema command is using the Config.ProviderTypes method,
which had not been kept up to date with the changes to provider
requirements detection made in Config.ProviderRequirements. This
resulted in any currently-unused providers being omitted from the
output.
This commit changes the ProviderTypes method to use the same underlying
logic as ProviderRequirements, which ensures that `required_providers`
blocks are taken into account.
Includes an integration test case to verify that this fixes the provider
schemas command bug.
The prior state recorded in the plans did not match the actual prior
state. Make the plans and state match depending on whether there was
existing state or not.
Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.
Derived from code in this repository, MIT licensed:
https://github.com/apparentlymart/terraform-provider-testing
Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.
Update tests to match the fix in mitchellh/cli#71, which aligns MockUi
with BasicUi and allows newlines in user input.
We are not using the new ErrorWriter, added in mitchellh/cli#81, as it
does not appear to interact correctly with panicwrap. All error output
from CLI parsing will continue to appear on stdout, not stderr.
Mark sensitivity on a value. However, when the value is encoded to send to the
provider to produce a changeset we must remove the marks, so unmark the value
and remark it with the saved path afterwards
When rendering a diff between current state and projected state, we only
show resources and outputs which have changes. However, we show a full
structural diff for these values, which includes all attributes and
blocks for a changed resource or output. The result can be a very long
diff, which makes it difficult to verify what the changed fields are.
This commit adds an experimental concise diff renderer, which suppresses
most unchanged fields, only displaying the most relevant changes and
some identifying context. This means:
- Always show all identifying attributes, initially defined as `id`,
`name`, and `tags`, even if unchanged;
- Only show changed, added, or removed primitive values: `string`,
`number`, or `bool`;
- Only show added or removed elements in unordered collections and
structural types: `map`, `set`, and `object`;
- Show added or removed elements with any surrounding unchanged elements
for sequence types: `list` and `tuple`;
- Only show added or removed nested blocks, or blocks with changed
attributes.
If any attributes, collection elements, or blocks are hidden, a count
is kept and displayed at the end of the parent scope. This ensures that
it is clear that the diff is only displaying a subset of the resource.
The experiment is currently enabled by default, but can be disabled by
setting the TF_X_CONCISE_DIFF environment variable to 0.
This new option is intended to address the previous inconsistencies where
some older subcommands supported partially changing the target directory
(where Terraform would use the new directory inconsistently) where newer
commands did not support that override at all.
Instead, now Terraform will accept a -chdir command at the start of the
command line (before the subcommand) and will interpret it as a request
to direct all actions that would normally be taken in the current working
directory into the target directory instead. This is similar to options
offered by some other similar tools, such as the -C option in "make".
The new option is only accepted at the start of the command line (before
the subcommand) as a way to reflect that it is a global command (not
specific to a particular subcommand) and that it takes effect _before_
executing the subcommand. This also means it'll be forced to appear before
any other command-specific arguments that take file paths, which hopefully
communicates that those other arguments are interpreted relative to the
overridden path.
As a measure of pragmatism for existing uses, the path.cwd object in
the Terraform language will continue to return the _original_ working
directory (ignoring -chdir), in case that is important in some exceptional
workflows. The path.root object gives the root module directory, which
will always match the overriden working directory unless the user
simultaneously uses one of the legacy directory override arguments, which
is not a pattern we intend to support in the long run.
As a first step down the deprecation path, this commit adjusts the
documentation to de-emphasize the inconsistent old command line arguments,
including specific guidance on what to use instead for the main three
workflow commands, but all of those options remain supported in the same
way as they were before. In a later commit we'll make those arguments
produce a visible deprecation warning in Terraform's output, and then
in an even later commit we'll remove them entirely so that -chdir is the
single supported way to run Terraform from a directory other than the
one containing the root module configuration.
Most of the functionality for rendering output changes is covered by the
tests for ResourceChanges, as they both share the same diff renderer.
This commit adds a few tests to cover some of the output specific code.
* Return an error on unlock failure
When the lock can't be released return the err even if there is no previous error with the current action. This allows faster failure in CI/CD systems. Without this failure to remove the lock would result in the failure happening on a subsequent plan or apply which slows down the feedback loop in automated systems.

When init attempts to install a legacy provider required by state and
fails, but another provider with the same type is successfully
installed, this almost definitely means that the user is migrating an
in-house provider. The solution here is to use the `terraform state
replace-provider` subcommand.
This commit makes that next step clearer, by detecting this specific
case, and displaying a list of commands to fix the existing state
provider references.
Diagnostic detail lines sometimes contain lines which include commands
suggested for the user to execute. By convention, these start with
leading whitespace to indicate that they are not prose.
This commit changes the diagnostic formatter to wrap each line of the
detail separately, and skips word wrapping for lines prefixed with
space. This prevents ugly and confusing wrapping of long command lines.
This pull reverts a recent change to backend/local which created two context, one with and one without state. Instead I have removed the state entirely from the validate graph (by explicitly passing a states.NewState() to the validate graph builder).
This changed caused a test failure, which (ty so much for the help) @jbardin discovered was inaccurate all along: the test's call to `Validate()` was actually what was removing the output from state. The new expected test output matches terraform's actual behavior on the command line: if you use -target to destroy a resource, an output that references only that resource is *not* removed from state even though that test would lead you to believe it did.
This includes two tests to cover the expected behavior:
TestPlan_varsUnset has been updated so it will panic if it gets more than one request to input a variable
TestPlan_providerArgumentUnset covers #26035Fixes#26035, #26027
If a provider changes namespace in the registry, we can detect this when
running the 0.13upgrade command. As long as there is a version matching
the user's constraints, we now use the provider's new source address.
Otherwise, warn the user that the provider has moved and a version
upgrade is necessary to move to it.
When the output subcommand is called with no arguments, and there are no
outputs to show, we previously rendered an error message but returned a
non-error status code. This is confusing.
This commit changes the text UI to use a warning diagnostic, which makes
it clearer that this is a non-error situation. We do not change the exit
code or the text of the warning, so hopefully this is not considered a
breaking change.
When applying a backend config override file, we must not check for the
presence of all required fields, as the override can be a partial
configuration. It is only valid to check for required fields after all
overrides have been merged, which init already does.
When loading a backend config override file, init was doing two things
wrong:
- First, if the file failed to parse, we accidentally didn't return,
which caused a panic due to the parsed body being nil;
- Secondly, we were overzealous with the validation of the file,
allowing only attributes. While most backend configs are attributes
only, the enhanced remote backend body also contains a `workspaces`
block, which we need to support here.
This commit fixes the first bug with an early return and adds test cases
for missing file and intentionally-blank filename (to clear the config).
We also add a schema validation for the backend block, based on the
backend schema itself. This requires constructing an HCL body schema so
that we can call `Content` and check for diagnostic errors.
The result is more useful errors when an invalid backend config override
file is used, while also supporting the enhanced remote backend config
fully.
Does not include tests specific to the remote backend, because the
mocking involved to allow the backend to fully initialize is too
involved to be worth it.
If a module has multiple terraform.required_version constraints, any
failures would point at the last constraint in the error diagnostics. If
an earlier constraint was the actual problem, this leads to confusing
errors like this:
Error: Unsupported Terraform Core version
on main.tf line 6, in terraform:
6: required_version = ">= 0.13.0"
This configuration does not support Terraform version 0.13.0.
The error was due to storing the declaration range of the constraint as
a pointer to the contents of a loop variable, which was later
overwritten in later iterations of the loop. Instead we now use HCL's
handy Ptr() method to create a direct pointer to the range struct.
Include the import walk in the list of operations for which we create an
EvalModuleCallArgument node. This causes module call arguments to be
evaluated even if the module variables have defaults, ensuring that
invalid default values (such as the common "{}" for variables thought of
as maps) do not cause failures specific to import.
This fixes a bug where a child module evaluates an input variable in its
locals block, assuming that it is a nested object structure. The bug
report includes a default value of "{}", which is overridden by a root
variable value. Without the eval node added in this commit, the default
value is used and the local evaluation errors.
If somehow an invalid workspace has been selected, the Meta.Workspace
method should not return an error, to ensure that we don't break any
existing workflows with invalid workspace names.
We are validating the workspace name for all workspace commands. Due to
a bug with the TF_WORKSPACE environment variable, it has been possible
to accidentally create a workspace with an invalid name.
This commit removes the valid workspace name check for workspace delete
to allow users to clean up any invalid workspaces.
The workspace name can be overridden by setting a TF_WORKSPACE
environment variable. If this is done, we should still validate the
resulting workspace name; otherwise, we could end up with an invalid and
unselectable workspace.
This change updates the Meta.Workspace function to return an error, and
handles that error wherever necessary.
When moving a resource block with multiple instances to a new address
within the same module, we need to ensure that the target module is
present as late as possible. Otherwise, deleting the resource from the
original address triggers pruning, and the module is removed just before
we try to add the resource to it, which causes a crash.
Includes regression test which panics without this code change.
Most of the state package has been deprecated by the states package.
This PR replaces all the references to the old state package that
can be done simply - the low-hanging fruit.
* states: move state.Locker to statemgr
The state.Locker interface was a wrapper around a statemgr.Full, so
moving this was relatively straightforward.
* command: remove unnecessary use of state package for writing local terraform state files
* move state.LocalState into terraform package
state.LocalState is responsible for managing terraform.States, so it
made sense (to me) to move it into the terraform package.
* slight change of heart: move state.LocalState into clistate instead of
terraform
* unlock the state if Context() has an error, exactly as backend/remote does today
* terraform console and terraform import will exit before unlocking state in case of error in Context()
* responsibility for unlocking state in the local backend is pushed down the stack, out of backend.go and into each individual state operation
* add tests confirming that state is not locked after apply and plan
* backend/local: add checks that the state is unlocked after operations
This adds tests to plan, apply and refresh which validate that the state
is unlocked after all operations, regardless of exit status. I've also
added specific tests that force Context() to fail during each operation
to verify that locking behavior specifically.
This code was made to do nothing pre-0.12, and we have no plans to
reintroduce a diff in the apply output, so it seems reasonable to now
remove it altogether.
A lingering FIXME caused missing configuration from provider config
blocks in the json output of terraform plan. This fixes the regression
and adds a test. For the sake of testing, I added an optional attribute
to the show test provider, which resulted in the providers schema test
getting an update - not a bad addition, but we can always add a
test-specific provider schema as needed.
If the user specifies a host that isn't a provider registry in a provider
source address then we'll print out some specialized error messages for
different variants of that situation.
In particular, this includes a special case for when the error is on the
hostname "github.com", in anticipation of folks incorrectly attempting to
use GitHub repository URLs (or Go-style module paths that happen to be
on GitHub) to specify providers, so we can give a more specific hint about
that.
This is just a different presentation of an existing error case that we
are already covering in the installer tests, so there are no new tests
here. We could in principle have a test covering the exact text of these
error messages, but we don't have much precedent for command package tests
covering that level of cosmetic detail.
For Terraform v0.12 we introduced a special loading mode where we would
use the 0.11-syntax-compatible "earlyconfig" package as a heuristic to
identify situations where it was likely that the user was trying to use
0.11-only syntax that the upgrade tool might help with.
However, as the language has moved on that is no longer a suitable
heuristic in Terraform 0.13 and later: other new additions to the
language can cause the main loader to disagree with earlyconfig, which
would lead us to give poor advice about how to respond.
Instead, we'll now return the same generic "there are errors" message in
all syntax error cases. We have an extra message for errors in this
case (as compared to other commands) because "terraform init" is usually
the first command a new user interacts with and so this message gives some
extra explanation about what "terraform init" will do with the
configuration once it's valid.
This also includes a reset control character in the output of the message
as part of our ongoing mission to stop Terraform printing out whole
paragraphs of colored text, which can often be hard to read for various
reasons.
After installing providers, we validate the presence of an executable
file, and generate a selected versions lockfile. If this process fails,
notify the user. One possible cause for this is an invalid provider
package with a missing or misnamed executable file.
Instead of searching the installed provider package directory for a
binary as we install it, we can lazily detect the executable as it is
required. Doing so allows us to separately report an invalid unpacked
package, giving the user more actionable error messages.
* command/console: return in case of errors before trying to unlock remote
state
The remote backend `Context` would exit without an active lock if there
was an error, while the local backend `Context` exited *with* a lock. This
caused a problem in `terraform console`, which would call unlock
regardless of error status.
This commit makes the local and remote backend consistently unlock the
state incase of error, and updates terraform console to check for errors
before trying to unlock the state.
* adding tests for remote and local backends
* command/init: return an error with invalid -backend-config files
The -backend-config flag expects a set of key-value pairs or a file
containing key-value pairs. If the file instead contains a full backend
configuration block, it was silently ignored. This commit adds a check
for blocks in the file and returns an error if they are encountered.
Fixes#24845
* emphasize backend configuration file in docs
This is for consistency with other commands which use prompts, all of
which require "yes" rather than "y" to confirm.
We also migrate the login command to use UIInput, which now supports
securely asking for passwords or secrets via the speakeasy library.
* internal/getproviders: decode and return any registry warnings
The public registry may include a list of warnings in the "versions"
response for any given provider. This PR adds support for warnings from
the registry and an installer event to return those warnings to the
user.
Previously, any comments inside the required provider configuration for
a given provider would be wiped out upon rerunning the 0.13upgrade
command. This commit attempts to preserve those comments if the existing
entry is semantically equivalent to the entry we are about to write.
* command: adjust exit code of state rm and state mv
Commands `state rm` and `state mv` will now exit with code 1 when the
target resource is not found in the current state.
This is consistent with `terraform state show non_existent_resource`.
Fixes#17800
We previously intentionally removed support for the allow-missing-config
option to terraform import, requiring that all imported resources have
matching config. See #24412.
However, the option was not removed from the import command, and it is
widely used. This commit reintroduces support for importing with a
missing configuration by falling back to implying the provider FQN based
on the resource type.
When using `-flag=value` with Powershell, unquoted values are broken
into separate arguments. This means that the following command:
terraform init -backend-config=./backend.conf
is interpreted by Terraform as:
terraform init -backend-config= ./backend.conf
This results in an empty backend-config setting (which is semantically
valid!) followed by a custom configuration path (pointing at a file).
Due to a bug where we could exit without printing diagnostics, this
would result in a silent failure that was very difficult to diagnose.
Some of the tests in the command package were running directly on the
fixture directories, and modifying or locking files within them. This
could cause state to leak between tests.
This commit cleans up all such cases that I could find.
We globally support a -v/-version/--version flag, which triggers the
version subcommand. The recent introduction of JSON output support meant
we started parsing the flags for the first time, but we didn't add flags
for these global version arguments.
This commit adds those flags (but doesn't check them, since they have no
effect on the version command itself). Also adds usage information for
terraform version.
The positional argument passed to apply was once used to specify a
source for a Terraform module to fetch and initialize (#337). This
functionality was removed from the init command later (#15032) but not
completely removed from apply.
This code was non-functional but largely not harmful, except for a very
specific case: when passing an absolute path to a plan file as the
positional argument on Windows, the getter.Detect code would incorrectly
interpret the path as a URL. This caused init to fail and the apply
command would exit with code 1 but without diagnostics.
This commit removes this codepath, which fixes this bug, and should
otherwise have no effect on the supported behaviour of apply.
This new version permits omitting the space between the operator and the
boundary in a ruby-style version constraint, like ">1.0.0" instead of
"> 1.0.0".
When initializing a configuration which refers to re-namespaced legacy
providers, we attempt to detect this and display a diagnostic message.
Previously this message would direct the user to run the 0.13upgrade
command, but without specifying in which directories.
This commit detects which modules are using the providers in question,
and for local modules displays a list of upgrade commands which specify
the source directories of these modules.
For remote modules, we display a separate list noting that they need to
be upgraded elsewhere, providing both the local module call name and the
module source address.
Providers can be required from multiple sources. The previous
implementation of the providers sub-command displayed only a flat list
of provider requirements, which made it difficult to see which modules
required each provider.
This commit reintroduces the tree display of provider requirements, and
adds a separate output block for providers required by existing state.
I feel the current confirmation prompt for 0.13upgrade command is
ambiguous what is expected. Actually, when I used it for the first time,
I cancelled it by typing `y` instead of `yes`.
I believe it would be great if the 0.13upgrade command tell us the
expected value for confirmation like 0.12upgrade.
Diagnostics where the highlight range has an empty overlap with a line
would skip lines of the output. This is because if two ranges abut each
other, they can be considered to overlap, but that overlap is empty.
This results in an edge case in the diagnostic printer which causes the
line not to be printed.
This new command is intended to make it easy to create or update a mirror
directory containing suitable providers for the current configuration,
producing a layout that is appropriate both for a filesystem mirror or,
if copied into the document root of an HTTP server, a network mirror.
This initial version is not customizable aside from being able to select
multiple platforms to install packages for.
Future iterations of this could include commands to turn the JSON index
generation on and off, or to instruct it to produce the unpacked directory
layout instead of the packed directory layout as it currently does. Both
of those options would make the generated directory unsuitable to be
a network mirror, but it would still work as a filesystem mirror.
In the long run this will hopefully form part of a replacement workflow to
terraform-bundle as a way to put copies of providers somewhere so we don't
need to re-download them every time, but some other changes will be needed
outside of just this command before that'd be true, such as adding support
for network and/or filesystem mirrors in Terraform Enterprise.
This is a baby-step towards an intended future where all Terraform actions
which have side-effects in either remote objects or the Terraform state
can go through the plan+apply workflow.
This initial change is focused only on allowing plan+apply for changes to
root module output values, so that these can be written into a new state
snapshot (for consumption by terraform_remote_state elsewhere) without
having to go outside of the primary workflow by running
"terraform refresh".
This is also better than "terraform refresh" because it gives an
opportunity to review the proposed changes before applying them, as we're
accustomed to with resource changes.
The downside here is that Terraform Core was not designed to produce
accurate changesets for root module outputs. Although we added a place for
it in the plan model in Terraform 0.12, Terraform Core currently produces
inaccurate changesets there which don't properly track the prior values.
We're planning to rework Terraform Core's evaluation approach in a
forthcoming release so it would itself be able to distinguish between the
prior state and the planned new state to produce an accurate changeset,
but this commit introduces a temporary stop-gap solution of implementing
the logic up in the local backend code, where we can freeze a snapshot of
the prior state before we take any other actions and then use that to
produce an accurate output changeset to decide whether the plan has
externally-visible side-effects and render any changes to output values.
This temporary approach should be replaced by a more appropriately-placed
solution in Terraform Core in a release, which should then allow further
behaviors in similar vein, such as user-visible drift detection for
resource instances.
Fetching a default namespace provider from the public registry can
result in 404 Not Found error. This might be caused by a previously-
default provider moving to a new namespace, which means that the
configuration needs to be upgraded to use an explicit provider source.
This commit adds a more detailed diagnostic for this situation,
suggesting that the intended provider might be in a new namespace. The
recommended course of action is to run the 0.13upgrade command to
generate the correct required_providers configuration.
This adds supports for "unmanaged" providers, or providers with process
lifecycles not controlled by Terraform. These providers are assumed to
be started before Terraform is launched, and are assumed to shut
themselves down after Terraform has finished running.
To do this, we must update the go-plugin dependency to v1.3.0, which
added support for the "test mode" plugin serving that powers all this.
As a side-effect of not needing to manage the process lifecycle anymore,
Terraform also no longer needs to worry about the provider's binary, as
it won't be used for anything anymore. Because of this, we can disable
the init behavior that concerns itself with downloading that provider's
binary, checking its version, and otherwise managing the binary.
This is all managed on a per-provider basis, so managed providers that
Terraform downloads, starts, and stops can be used in the same commands
as unmanaged providers. The TF_REATTACH_PROVIDERS environment variable
is added, and is a JSON encoding of the provider's address to the
information we need to connect to it.
This change enables two benefits: first, delve and other debuggers can
now be attached to provider server processes, and Terraform can connect.
This allows for attaching debuggers to provider processes, which before
was difficult to impossible. Second, it allows the SDK test framework to
host the provider in the same process as the test driver, while running
a production Terraform binary against the provider. This allows for Go's
built-in race detector and test coverage tooling to work as expected in
provider tests.
Unmanaged providers are expected to work in the exact same way as
managed providers, with one caveat: Terraform kills provider processes
and restarts them once per graph walk, meaning multiple times during
most Terraform CLI commands. As unmanaged providers can't be killed by
Terraform, and have no visibility into graph walks, unmanaged providers
are likely to have differences in how their global mutable state behaves
when compared to managed providers. Namely, unmanaged providers are
likely to retain global state when managed providers would have reset
it. Developers relying on global state should be aware of this.
Relying on the early config for provider requirements was necessary in
Terraform 0.12, to allow the 0.12upgrade command to run after init
installs providers.
However in 0.13, the same restrictions do not apply, and the detection
of provider requirements has changed. As a result, the early config
loader gives incorrect provider requirements in some circumstances,
such as those in the new test in this commit.
Therefore we are changing the init command to use the requirements found
by the full configuration loader. This also means that we can remove the
internal initwd CheckCoreVersionRequirements function.
provider is not found.
Previously a user would see the following error even if terraform was
only searching the local filesystem:
"provider registry registry.terraform.io does not have a provider named
...."
This PR adds a registry-specific error type and modifies the MultiSource
installer to check for registry errors. It will return the
registry-specific error message if there is one, but if not the error
message will list all locations searched.
* providercache: add logging for errors from getproviders.SearchLocalDirectory
providercache.fillMetaCache() was silently swallowing errors when
searching the cache directory. This commit logs the error without
changing the behavior otherwise.
* command/cliconfig: validate plugin cache dir exists
The plugin cache directory must exist for terraform to use it, so we
will add a check at the begining.
Previously the diagnostics from the config loaders (earlyconfig and
regular) were only appended to the overall diags if an error was found.
This adds all diagnostics from the regular config loader so that any
generated warnings will be displayed, even if there are no errors.
I did not add the `earlyconfig` warnings since they will be displayed if
there is an error and are likely to be duplicated by the config loader.
* internal/registry source: return error if requested provider version protocols are not supported
* getproviders: move responsibility for protocol compatibility checks into the registry client
The original implementation had the providercache checking the provider
metadata for protocol compatibility, but this is only relevant for the
registry source so it made more sense to move the logic into
getproviders.
This also addresses an issue where we were pulling the metadata for
every provider version until we found one that was supported. I've
extended the registry client to unmarshal the protocols in
`ProviderVersions` so we can filter through that list, instead of
pulling each version's metadata.
When looking up the namespace for a legacy provider source, we need to
use the /v1/providers/-/{name}/versions endpoint. For non-HashiCorp
providers, the /v1/providers/-/{name} endpoint returns a 404.
This commit updates the LegacyProviderDefaultNamespace method and the
mock registry servers accordingly.
If a configuration had multiple blocks in the versions.tf file, it would
be added to the `rewritePaths` list multiple times. We would then remove
it from this slice, but only once, and so the output file would later be
rewritten to remove the required providers block.
This commit uses a set instead of a list to prevent this case, and adds
a regression test.
Instead of using providers.tf as the default output file for the
upgrader, we now default to versions.tf. This means that if the
configuration has no `required_providers` blocks at all, or has
multiple, the provider version requirements will be stored in the
versions.tf file.
We now also update the versions.tf file to set a `required_version`
attribute in the first `terraform` block, with value ">= 0.13". This
is similar to the behaviour of the 0.12upgrade command, and signals that
the configuration should not be used with older versions of Terraform.
This commit implements most of the intended functionality of the upgrade
command for rewriting configurations.
For a given module, it makes a list of all providers in use. Then it
attempts to detect the source address for providers without an explicit
source.
Once this step is complete, the tool rewrites the relevant configuration
files. This results in a single "required_providers" block for the
module, with a source for each provider.
Any providers for which the source cannot be detected (for example,
unofficial providers) will need a source to be defined by the user. The
tool writes an explanatory comment to the configuration to help with
this.
Providers like Okta and AWS Cognito expect that the PKCE challenge
uses base64 URL Encoding without any padding (base64.RawURLEncoding)
Additionally, Okta strictly adheres to section 4.2 of RFC 7636 and
requires that the unencoded key for the PKCE data is at least 43
characters in length.
The only situation where `state mv` needs to understand the each mode is
when with resource addresses that may reference a single instance, or a
group of for_each or count instances. In this case we can differentiate
the two by checking the existence of the NoKey instance key.
* Include eval in output walk
This allows outputs to be evaluated in the evalwalk,
impacting terraform console. Outputs are still not evaluated
for terraform console in the root module, so this has
no impact on writing to state (as child module outputs are not
written to state). Also adds test coverage to the console command,
including for evaluating locals (another use of the evalwalk)
These were being used in an earlier iteration of the provider installation
configuration but it was all collapsed down into a single
ProviderInstallationMethod type later, making these redundant.
This exercises the ability to customize the installation methods used by
the provider plugin installer, in this case forcing the use of a custom
local directory with a result essentially the same as what happens when
you pass -plugin-dir to "terraform init".
The CLI config can be written in both native HCL and HCL JSON syntaxes, so
the provider_installation block must be expressible using JSON too. Our
previous checks to approximate HCL 2-level strictness were too strict for
HCL JSON where things are more ambiguous even in HCL 2, so this includes
some additional relaxations if we detect that we're decoding an AST
produced from a JSON file.
This is still subject to the quirky ways HCL 1 handles JSON though, so
the JSON value must be structured in a way that doesn't trigger HCL's
heuristics that try to guess what is a block and what is an attribute.
(This is the issue that HCL 2 fixes by always decoding using a schema;
there's more context on this in:
https://log.martinatkins.me/2019/04/25/hcl-json/ )
Unfortunately in the user model the noun "source" is already used for the
argument in the required_providers block to specify which provider to use,
so it's confusing to use the same noun to also refer to the method used to
obtain that provider.
In the hope of mitigating that confusion, here we use the noun "method",
as in "installation method", to talk about the decision between getting
a provider directly from its origin registry or getting it from some
mirror. This is distinct from the provider's "source", which is the
location where a provider _originates_ (prior to mirroring).
This noun is also not super awesome, but better than overloading an
existing term in the same feature.
In the first pass of implementing this it was strict about what arguments
are allowed inside source blocks, but that was counter to our usual design
principles for CLI config where we tend to ignore unrecognized things to
allow for some limited kinds of future expansion without breaking
compatibility with older versions of Terraform that will be sharing the
same CLI configuration files with newer versions.
However, I'd removed the tracking of that prior to the initial commit. I
missed some leftover parts when doing that removal, so this cleans up the
rest of it.
An earlier commit added a redundant stub for a new network mirror source
that was already previously stubbed as HTTPMirrorSource.
This commit removes the unnecessary extra stub and changes the CLI config
handling to use it instead. Along the way this also switches to using a
full base URL rather than just a hostname for the mirror, because using
the usual "Terraform-native service discovery" protocol here doesn't isn't
as useful as in the places we normally use it (the mirror mechanism is
already serving as an indirection over the registry protocol) and using
a direct base URL will make it easier to deploy an HTTP mirror under
a path prefix on an existing static file server.
When we originally introduced this environment variable it was intended to
solve for the use-case where a particular invocation of Terraform needs
a different CLI configuration than usual, such as if Terraform is being
run as part of an automated test suite or other sort of automated
situation with different needs than normal use.
However, we accidentally had it only override the original singleton CLI
config file, while leaving the CLI configuration directory still enabled.
Now we'll take the CLI configuration out of the equation too, so that only
the single specified configuration file and any other environment-sourced
settings will be included.
* internal/providercache: verify that the provider protocol version is
compatible
The public registry includes a list of supported provider protocol
versions for each provider version. This change adds verification of
support and adds a specific error message pointing users to the closest
matching version.
This new CLI config block type allows explicitly specifying where
Terraform should look to find provider plugins for installation. This is
not used anywhere as of this commit, but in a future commit we'll change
package main to treat the presence of a block of this type as a request
to disable the default set of provider sources and use these explicitly-
specified ones instead.
A side effect of the various changes to the provider installer included losing the initialization required error message which would occur if a user removed or modified the .terraform directory.
Previously, plugin factories were created after the configuration was loaded, in terraform.NewContext. Terraform would compare the required providers (from config and state) to the available providers and return the aforementioned error if a provider was missing.
Provider factories are now loaded at the beginning of any terraform command, before terraform even loads the configuration, and therefore before terraform has a list of required providers.
This commit replaces the current error when a providers' schema cannot be found in the provider factories with the init error, and adds a command test (to plan tests, for no real reason other than that's what I thought of first).
This more closely replicates the 0.12-and-earlier behavior, where having
at least one version of a provider installed locally would totally disable
any attempt to look for newer versions remotely.
This is just for the implicit default behavior. Assumption is that later
we'll have an explicit configuration mechanism that will allow the user
to specify exactly where to look for what, and thus avoid tricky
heuristics like this.
Providers installed from the registry are accompanied by a list of
checksums (the "SHA256SUMS" file), which is cryptographically signed to
allow package authentication. The process of verifying this has multiple
steps:
- First we must verify that the SHA256 hash of the package archive
matches the expected hash. This could be done for local installations
too, in the future.
- Next we ensure that the expected hash returned as part of the registry
API response matches an entry in the checksum list.
- Finally we verify the cryptographic signature of the checksum list,
using the public keys provided by the registry.
Each of these steps is implemented as a separate PackageAuthentication
type. The local archive installation mechanism uses only the archive
checksum authenticator, and the HTTP installation uses all three in the
order given.
The package authentication system now also returns a result value, which
is used by command/init to display the result of the authentication
process.
There are three tiers of signature, each of which is presented
differently to the user:
- Signatures from the embedded HashiCorp public key indicate that the
provider is officially supported by HashiCorp;
- If the signing key is not from HashiCorp, it may have an associated
trust signature, which indicates that the provider is from one of
HashiCorp's trusted partners;
- Otherwise, if the signature is valid, this is a community provider.
The providers command has been refactored to use the modern provider types and
ProviderRequirements() functions. This resulted in a breaking change to
the output: it no longer outputs the providers by module and no longer
prints `(inherited)` or `(from state)` to show why a provider is
included. We decided that at this time it was best to stick with the
existing functions and make this change, but if we get feedback from the
community we will revisit.
Additional tests to exercise providers in modules and providers from
state have been included.
This PR adds iteration through any provider configuration blocks in the
config in addProviderRequirements().
A stale comment (of mine!) would leave one expecting the
module.ProviderRequirements to include any requirements from provider
configs. The comment was inaccurate and has been updated.
When a provider dependency is implicit rather than explicit, or otherwise
when version constraints are lacking, we produce a warning recommending
the addition of explicit version constraints in the configuration.
This restores the warning functionality from previous Terraform versions,
adapting it slightly to account for the new provider FQN syntax and to
recommend using a required_providers block rather than version constraints
in "provider" blocks, because the latter is no longer recommended in the
documentation.
The fake installable package meta used a ZIP archive which gave
different checksums between macOS and Linux targets. This commit removes
the target from the contents of this archive, and updates the golden
hash value in the test to match. This test should now pass on both
platforms.
The provider fully-qualified name string used in configuration is very
long, and since most providers are hosted in the public registry, most
of that length is redundant. This commit adds and uses a `ForDisplay`
method, which simplifies the presentation of provider FQNs.
If the hostname is the default hostname, we now display only the
namespace and type. This is only used in UI, but should still be
unambiguous, as it matches the FQN string parsing behaviour.
This restores some of the local search directories we used to include when
searching for provider plugins in Terraform 0.12 and earlier. The
directory structures we are expecting in these are different than before,
so existing directory contents will not be compatible without
restructuring, but we need to retain support for these local directories
so that users can continue to sideload third-party provider plugins until
the explicit, first-class provider mirrors configuration (in CLI config)
is implemented, at which point users will be able to override these to
whatever directories they want.
This also includes some new search directories that are specific to the
operating system where Terraform is running, following the documented
layout conventions of that platform. In particular, this follows the
XDG Base Directory specification on Unix systems, which has been a
somewhat-common request to better support "sideloading" of packages via
standard Linux distribution package managers and other similar mechanisms.
While it isn't strictly necessary to add that now, it seems ideal to do
all of the changes to our search directory layout at once so that our
documentation about this can cleanly distinguish "0.12 and earlier" vs.
"0.13 and later", rather than having to document a complex sequence of
smaller changes.
Because this behavior is a result of the integration of package main with
package command, this behavior is verified using an e2etest rather than
a unit test. That test, TestInitProvidersVendored, is also fixed here to
create a suitable directory structure for the platform where the test is
being run. This fixes TestInitProvidersVendored.
There was a remaining TODO in this package to find the true provider FQN
when looking up the schema for a resource type. We now have that data
available in the Provider field of configs.Resource, so we can now
complete that change.
The tests for this functionality actually live in the parent "command"
package as part of the tests for the "terraform show" command, so this
fix is verified by all of the TestShow... tests now passing except one,
and that remaining one is failing for some other reason which we'll
address in a later commit.
Built-in providers are special providers that are distributed as part of
Terraform CLI itself, rather than being installed separately. They always
live in the terraform.io/builtin/... namespace so it's easier to see that
they are special, and currently there is only one built-in provider named
"terraform".
Previous commits established the addressing scheme for built-in providers.
This commit makes the installer aware of them to the extent that it knows
not to try to install them the usual way and it's able to report an error
if the user requests a built-in provider that doesn't exist or tries to
impose a particular version constraint for a built-in provider.
For the moment the tests for this are the ones in the "command" package
because that's where the existing testing infrastructure for this
functionality lives. A later commit should add some more focused unit
tests here in the internal/providercache package, too.
* command: refactor testBackendState to write states.State
testBackendState was using the older terraform.State format, which is no
longer sufficient for most tests since the state upgrader does not
encode provider FQNs automatically. Users will run `terraform
0.13upgrade` to update their state to include provider FQNs in
resources, but tests need to use the modern state format instead of
relying on the automatic upgrade.
* plan tests passing
* graph tests passing
* json packages test update
* command test updates
* update show test fixtures
* state show tests passing
In the new design the ProviderSource is decided by package main, not by
the "command" package, and so making sure the vendor directory is included
is the responsibility of that package instead. Therefore we can no longer
test this at the "command" package level, but we'll retain a test for it
in e2etests to record that it isn't currently working, so that we have
a prompt to fix it before releasing.
Due to some incomplete rework of this function in an earlier commit, the
safety check for using the same directory as both the target and the
cache was inverted and was raising an error _unless_ they matched, rather
than _if_ they matched.
This change is verified by the e2etest TestInitProviders_pluginCache,
which is also updated to use the new-style cache directory layout as part
of this commit.
These tests make assertions against specific user-oriented output from the
"terraform init" command, but we've intentionally changed some of these
messages as part of introducing support for the decentralized provider
namespace.
Both of these are attempting to test -plugin-dir, which means we need some
additional help to populate some suitable directories for -plugin-dir to
refer to. The new installFakeProviderPackagesElsewhere helper generalizes
the earlier installFakeProviderPackages to allow installing fake provider
packages to an arbitrary other directory.
This test is focused on making sure that the required_providers syntax
is working, so the rewritten version does not include any special handling
of pre-installed packages or "vendored" packages. Pre-installed plugins
are tested in other tests such as TestInit_getUpgradePlugins.
This test now requires a bit of a different approach because it was
previously directly constructing a cache directory but we now use a
different directory layout.
Rather than manually constructing the new heirarchical directory layout
(which would've required a lot more inline code), this introduces a helper
function installFakeProviderPackages that installs a fake provider package
directly into the local cache directory associated with a Meta object,
with the correct directory layout.
This is a slightly different approach than we used to take for this
option: rather than disabling the installer and causing all future
commands to look elsewhere for plugins, we'll now leave the installer
enabled by constrain it to only look at the given directories.
This is overall simpler because it doesn't require any special tracking
of the plugin directories for subsequent commands. Instead, the selections
file generated by the installer will record the versions it selected from
the specified directories, and we'll link them in to the local cache just
as we would normally so that other commands don't need to do anything
special to select the right plugins in either case.
They still aren't passing, but this is just enough updating to make the
test program compile successfully after the refactoring related to
provider installation. They are now using the mock provider source offered
by the getproviders package, which is similar but not totally identical
to the idea of mocking the entire installer as these tests used to do, and
so many of them need further adjustment to still be testing what they
intended to test under this new architecture.
Subsequent commits will gradually repair the failing tests.
* terraform: add helper functions for creating test state
testSetResourceInstanceCurrent and testSetResourceInstanceTainted are
wrapper functions around states.Module.SetResourceInstanceCurrent()
used to set a resource in state. They work with current, non-deposed
resources with no dependencies.
testSetResourceInstanceDeposed can be used to set a desosed resource in state.
* terraform: update all tests to use modern providers and state
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.
There's still a lot of work to do here around both the UX and the
follow-up steps that need to happen after installation completes, but this
is enough to faciliate some initial end-to-end testing of the new-style
install process.
Terraform 0.13 will allow the installation of providers from various
sources. If a user updates their configuration to change the source of
an in-use provider (for example, if the provider namespace changes),
they will also need to update the state file accordingly.
This commit introduces a new `state replace-provider` subcommand which
supports this. All resources using the `from` provider will be updated
to use the `to` provider.
Previously, if a diagnostic context spanned multiple lines, any lines
which did not overlap with the highlight range would be displayed as
blank. This commit fixes the bug.
The problem was caused by the unconditional use of `PartitionAround` to
split the line into before/highlighted/after ranges. When two ranges
don't overlap, this method returns empty ranges, which results in a
blank line. Instead, we first check if the ranges do overlap, and if not
we print the entire line from the context.
Previously, diagnostic errors would display the filename and line
number, along with "(source code not available)". This is because the
fmt command directly loads and parses the configuration, instead of
using the config loader.
This commit registers the manually parsed source as a synthetic
configuration file, so that the diagnostic formatter can look up the
source for the range with the error and display it.
These new functions allow command implementations to get hold of the
providercache objects and installation source object derived from the
current CLI configuration.
missingPlugins was hard-coded to work only with provider plugins, so I
renamed it to clarify the usage.
Also renamed a test provider from greater_than to greater-than as the
underscore is an invalid provider name character and this will become a
hard error in the near future.

Our initial Terraform 0.13.0 release will continue to support only the
hard-coded official HashiCorp signing key, with support for other keys to
follow in a later release once the trust infrastructure is in place to
support that.
This change is intended to (marginally) improve the UX for a possible
future situation where a HashiCorp-distributed provider makes a released
signed with a new key and a prior version of Terraform ends up trying to
install it due to incorrect version constraints. With this new text we
hope to give the user a better prompt for onward troubleshooting, but
in a sort of hedging way because we have not yet finalized the details of
how new keys might roll out in practice.
Hopefully a user seeing this message would consult the release notes for
Terraform itself and for the provider in question and find some
as-yet-undetermined information about how to proceed.
If the decentralized trust model design comes together before the v0.13.0
release then we may make further amendments here to prepare for that, but
that work should not block the v0.13.0 release if other work concludes
first.

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.

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

Following the same approach we use for other CLI-Config-able objects like
the service discovery system, the main package is responsible for
producing a suitable implementation of this interface which the command
package can then use.
When unit testing in the command package we can then substitute mocks as
necessary, following the dependency inversion principle.
The formatter in `command/format/state.go`, when formatting a resource
with an aliased provider, was looking for a schema with the alias (ie,
test.foo), but the schemas are only listed by provider type (test).
Update the state formatter to lookup schemas by provider type only.
Some of the show tests (and a couple others) were not properly cleaning
up the created tmpdirs, so I fixed those. Also, the show tests are using
a statefile named `state.tfstate`, but were not passing that path to the
show command, so we were getting some false positives (a `show` command
that returns `no state` exits 0).
Fixes#21462
* deps: bump terraform-config-inspect library
* configs: parse `version` in new required_providers block
With the latest version of `terraform-config-inspect`, the
required_providers attribute can now be a string or an object with
attributes "source" and "version". This change allows parsing the
version constraint from the new object while ignoring any given source attribute.
* command: use backend config from state when backend=false is used.
When a user runs `terraform init --backend=false`, terraform should
inspect the state for a previously-configured backend, and use that
backend, ignoring any backend config in the current configuration. If no
backend is configured or there is no state, return a local backend.
Fixes#16593
Clear any Dependencies if there is an entry matching a `state mv` from
address. While stale dependencies won't directly effect any current
operations, clearing the list will allow them to be recreated in their
entirety during refresh. This will help future releases that may rely
solely on the pre-calculated dependencies for destruction ordering.
* configs: move ProviderConfigCompact[Str] from addrs to configs
The configs package is aware of provider name and type (which are the
same thing today, but expected to be two different things in a future
release), and should be the source of truth for a provider config
address. This is an intermediate step; the next step will change the returned types to something based in the configs package.
* command: rename choosePlugins to chooseProviders to clarify scope of function
* use `Provider.LegacyString()` (instead of `Provider.Type`) consistently
* explicitly create legacy-style provider (continuing from above change)
When warnings appear in isolation (not accompanied by an error) it's
reasonable to want to defer resolving them for a while because they are
not actually blocking immediate work.
However, our warning messages tend to be long by default in order to
include all of the necessary context to understand the implications of
the warning, and that can make them overwhelming when combined with other
output.
As a compromise, this adds a new CLI option -compact-warnings which is
supported for all the main operation commands and which uses a more
compact format to print out warnings as long as they aren't also
accompanied by errors.
The default remains unchanged except that the threshold for consolidating
warning messages is reduced to one so that we'll now only show one of
each distinct warning summary.
Full warning messages are always shown if there's at least one error
included in the diagnostic set too, because in that case the warning
message could contain additional context to help understand the error.
The configs package is aware of provider name and type (which are the
same thing today, but expected to be two different things in a future
release), and should be the source of truth for a provider config
address.
* huge change to weave new addrs.Provider into addrs.ProviderConfig
* terraform: do not include an empty string in the returned Providers /
Provisioners
- Fixed a minor bug where results included an extra empty string
If a state mv target happens to be a resource that doesn't exist, allow
the creation of the new resource inferring the EachMode from the target
address.
* 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.
Some of our warnings are produced in response to particular configuration
constructs which might appear many times across a Terraform configuration.
To avoid the warning output dwarfing all of the other output, we'll use
ConsolidateWarnings to limit each distinct warning summary to appear at
most twice, and annotate the final one in the sequence with an additional
paragraph noting that some number of them have been hidden.
This is intended as a compromise to ensure that these warnings are still
seen and noted but to help ensure that we won't produce so many of them
as to distract from other output that appears alongside them.
This applies only to warnings relating to specific configuration ranges;
errors will continue to be shown individually, and sourceless warnings
(which are rare in Terraform today) will likewise remain ungrouped because
they are less likely to be repeating the same statement about different
instances of the same problem throughout the configuration.
Meta.backendConfig was incorrectly treating the second return value from
loadBackendConfig as if it were go "error" rather than
tfdiags.Diagnostics, which in turn meant that it would treat warnings like
errors.
This had confusing results because it still returned that
tfdiags.Diagnostics value in its own diagnostics return value, causing the
caller to see warnings even though the backendConfig function had taken
the error codepath.
We have a special treatment for multi-line strings that are being updated
in-place where we show them across multiple lines in the plan output, but
we didn't use that same treatment for rendering multi-line strings in
isolation such as when they are being added for the first time.
Here we detect when we're rendering a multi-line string in a no-change
situation and render it using the diff renderer instead, using the same
value for old and new and thus producing a multi-line result without any
diff markers at all.
This improves consistency between the change and no-change cases, and
makes multi-line strings (such as YAML in block mode) readable in all
cases.
The DestroyEdgeTransformer cannot determine ordering from the graph when
the destroyers are from orphaned resources, because there are no
references to resolve. The new stored Dependencies provides what we need
to connect the instances in this case.
We also add the StateDependencies method directly in the
GraphNodeResourceInstance interface, since all instances already
implement this, and we don't need another optional interface to check.
The old code in DestroyEdgeTransformer may no longer be needed in the
long run, but that can be determined separately, since too many of the
tests start with an incomplete state and rely on the Dependencies being
determined from the configuration alone.
This "Plan" type, along with the other types it directly or indirectly
embeds and the associated functions, are adaptations of the
flatmap-oriented plan renderer logic from Terraform 0.11 and prior.
The current diff rendering logic is in diff.go, and so the contents of the
plan.go file are defunct apart from the DiffActionSymbol function that
both implementations share. Therefore here we move DiffActionSymbol into
diff.go and then remove plan.go entirely, in the interests of dead code
removal.
During the Terraform 0.12 work we briefly had a partial update of the old
Terraform 0.11 (and prior) diff renderer that could work with the new
plan structure, but could produce only partial results.
We switched to the new plan implementation prior to release, but the
"terraform show" command was left calling into the old partial
implementation, and thus produced incomplete results when rendering a
saved plan.
Here we instead use the plan rendering logic from the "terraform plan"
command, making the output of both identical.
Unfortunately, due to the current backend architecture that logic lives
inside the local backend package, and it contains some business logic
around state and schema wrangling that would make it inappropriate to move
wholesale into the command/format package. To allow for a low-risk fix to
the "terraform show" output, here we avoid some more severe refactoring by
just exporting the rendering functionality in a way that allows the
"terraform show" command to call into it.
In future we'd like to move all of the code that actually writes to the
output into the "command" package so that the roles of these components
are better segregated, but that is too big a change to block fixing this
issue.
