Alisdair McDiarmid 0aa227e0e3 cli: Fix misapplied terminal colors on run logs
Due to calling the Colorize function with the full string instead of the
format string, plan/apply logs which include resource instance keys or
IDs which happen to match color formatting would be rendered
incorrectly.

This commit fixes this by only colorizing the known-safe format string.
We also add full test coverage for the UI hook, although only one of the
hooks is tested for this color bugfix due to verbosity of the test.

We also add the bold coloring to the provisioner output prefix, which
seems to have been an oversight.

Now that the view code is separated, we can increase test coverage in
unit tests. This commit moves some tests from the command package which
were testing only view code, and adds more new test cases.

Alisdair McDiarmid 2d1976bbda clistate: Update clistate.Locker for command views
The clistate package includes a Locker interface which provides a simple
way for the local backend to lock and unlock state, while providing
feedback to the user if there is a delay while waiting for the lock.
Prior to this commit, the backend was responsible for initializing the
Locker, passing through direct access to the cli.Ui instance.

This structure prevented commands from implementing different
implementations of the state locker UI. In this commit, we:

- Move the responsibility of creating the appropriate Locker to the
  source of the Operation;
- Add the ability to set the context for a Locker via a WithContext
  method;
- Replace the Locker's cli.Ui and Colorize members with a StateLocker
  view;
- Implement views.StateLocker for human-readable UI;
- Update the Locker interface to return detailed diagnostics instead of
  errors, reducing its direct interactions with UI;
- Add a Timeout() method on Locker to allow the remote backend to
  continue to misuse the -lock-timeout flag to cancel pending runs.

When an Operation is created, the StateLocker field must now be
populated with an implementation of Locker. For situations where locking
is disabled, this can be a no-op locker.

This change has no significant effect on the operation of Terraform,
with the exception of slightly different formatting of errors when state
locking or unlocking fails.

Alisdair McDiarmid a7b7cd29fc cli: Migrate Terraform UI hook to command views
Move the code which renders Terraform hook callbacks as UI into the
views package, backed by a views.View instead of a cli.Ui. Update test
setup accordingly.

To allow commands to control this hook, we add a hooks member on the
backend Operation struct. This supersedes the hooks in the Terraform
context, which is not directly controlled by the command logic.

This commit should not change how Terraform works, and is refactoring in
preparation for more changes which move UI code out of the backend.

Alisdair McDiarmid 536c80da23 backend: Add per-operation diagnostic rendering
The enhanced backends (local and remote) need to be able to render
diagnostics during operations. Prior to this commit, this functionality
was supported with a per-backend `ShowDiagnostics` function pointer.

In order to allow users of these backends to control how diagnostics are
rendered, this commit moves that function pointer to the `Operation`
type. This means that a diagnostic renderer is configured for each
operation, rather than once per backend initialization.

Some secondary consequences of this change:

- The `ReportResult` method on the backend is now moved to the
  `Operation` type, as it needs to access the `ShowDiagnostics` callback
  (and nothing else from the backend);
- Tests which assumed that diagnostics would be written to the backend's
  `cli.Ui` instance are migrated to using a new record/playback diags
  helper function;
- Apply, plan, and refresh commands now pass a pointer to the `Meta`
  struct's `showDiagnostics` method.

This commit should not change how Terraform works, and is refactoring in
preparation for more changes which move UI code out of the backend.

Alisdair McDiarmid 57879bfb71 cli: Add global view arguments parser
Rather than modifying and relying on the existing Meta.process
argument extractor, we can more clearly handle global CLI flags using
a separate parser step. This allows us to explicitly configure the view
in the command.

Alisdair McDiarmid c5a6aa31d3 cli: Add initial command views abstraction
Terraform supports multiple output formats for several sub-commands.
The default format is user-readable text, but many sub-commands support
a `-json` flag to output a machine-readable format for the result. The
output command also supports a `-raw` flag for a simpler, scripting-
focused machine readable format.

This commit adds a "views" abstraction, intended to help ensure
consistency between the various output formats. This extracts the render
specific code from the command package, and moves it into a views
package. Each command is expected to create an interface for its view,
and one or more implementations of that interface.

By doing so, we separate the concerns of generating the sub-command
result from rendering the result in the specified output format. This
should make it easier to ensure that all output formats will be updated
together when changes occur in the result-generating phase.

There are some other consequences of this restructuring:

- Views now directly access the terminal streams, rather than the
  now-redundant cli.Ui instance;
- With the reorganization of commands, parsing CLI arguments is now the
  responsibility of a separate "arguments" package.

For now, views are added only for the output sub-command, as an example.
Because this command uses code which is shared with the apply and
refresh commands, those are also partially updated.

Alisdair McDiarmid 4991cc4835 cli: Improve error for invalid -target flags
Errors encountered when parsing flags for apply, plan, and refresh were
being suppressed. This resulted in a generic usage error when using an
invalid `-target` flag.

This commit makes several changes to address this. First, these commands
now output the flag parse error before exiting, leaving at least some
hint about the error. You can verify this manually with something like:

    terraform apply -invalid-flag

We also change how target attributes are parsed, moving the
responsibility from the flags instance to the command. This allows us to
customize the diagnostic output to be more user friendly. The
diagnostics now look like:

```shellsession
$ terraform apply -no-color -target=foo

Error: Invalid target "foo"

Resource specification must include a resource type and name.
```

Finally, we add test coverage for both parsing of target flags, and at
the command level for successful use of resource targeting. These tests
focus on the UI output (via the change summary and refresh logs), as the
functionality of targeting is covered by the context tests in the
terraform package.

Alisdair McDiarmid 7cae76383a cli: Fix for provider requirements in JSON plan
The JSON plan output format includes a serialized, simplified version of
the configuration. One component of this config is a map of provider
configurations, which includes version constraints.

Until now, only version constraints specified in the provider config
blocks were exposed in the JSON plan output. This is a deprecated method
of specifying provider versions, and the recommended use of a
required_providers block resulted in the version constraints being
omitted.

This commit fixes this with two changes:

- When processing the provider configurations from a module, output the
  fully-merged version constraints for the entire module, instead of any
  constraints set in the provider configuration block itself;
- After all provider configurations are processed, iterate over the
  required_providers entries to ensure that any configuration-less
  providers are output to the JSON plan too.

No changes are necessary to the structure of the JSON plan output, so
this is effectively a semantic level bug fix.

Alisdair McDiarmid d7613a0aac cli: Better diagnostics for apply positional args
The previous changes removing support for using the trailing positional
argument as a working directory missed a spot in the apply/destroy
command implementation. We still support this argument for applying a
saved plan:

    terraform apply foo.tfplan

However, if you pass a positional path which doesn't "look like" a plan
(for example, the path to a configuration directory), Terraform would
silently ignore it and continue.

This commit fixes that by adding an error message if the user specifies
a path which the plan loader rejects as not "looking like" a plan. This
message includes a reference to the `-chdir` flag as a pointer about
what to do next.

We also rearrange the error message when calling `terraform destroy`
with a plan file argument, and add test coverage for the above. While
we're here, update the destroy tests to copy the fixture directory,
chdir, and defer cleanup.

Alisdair McDiarmid 888f36aebb cli: Remove positional plan argument from graph

Alisdair McDiarmid ca23a096d8 cli: Remove legacy positional path arguments
Several commands continued to support the legacy positional path
argument to specify a working directory. This functionality has been
replaced with the global -chdir flag, which is specified before any
other arguments, including the sub-command name.

This commit removes support for the trailing path parameter from
most commands. The only command which still supports a path argument is
fmt, which also supports "-" to indicate receiving configuration from
standard input.

Any invocation of a command with an invalid trailing path parameter will
result in a short error message, pointing at the -chdir alternative.

There are many test updates in this commit, almost all of which are
migrations from using positional arguments to specify a working
directory. Because of the layer at which these tests run, we are unable
to use the -chdir argument, so the churn in test files is larger than
ideal. Sorry!

Alisdair McDiarmid 5ca118b4e6 cli: Move resource count code to command package
CountHook is an implementation of terraform.Hook which is used to
calculate how many resources were added, changed, or destroyed during an
apply. This hook was previously injected in the local backend code,
which means that the apply command code has no access to these counts.

This commit moves the CountHook code into the command package, and
removes an unused instance of the hook in the plan code path. The goal
here is moving UI code into the command package.

Katy Moe 51c687c2db command: no visual warning hierarchy in -no-color
Commit e865faf adds visual indentation for diagnostic messages using various
vertical line characters. The present commit disables this behaviour when
running with colourised output disabled.

While the contents of stderr are not intended to be part of the Terraform API,
this is currently how the hashicorp/terraform-exec library detects certain
error types in order to present them as well-known Go errors to the user. Such
detection is complicated when vertical lines are added to the CLI output at
unpredictable points.

I expect this change will also be helpful for screen reader users.

Alisdair McDiarmid 212a97c3bd cli: Fix state migration remote version check
Previously the state migration process was using the fallback strict
error check when migrating to or from a Terraform Cloud workspace. This
resulted in an error when running init if the local and remote Terraform
versions did not exactly match.

This was excessively strict. When migrating from a remote Terraform
Cloud workspace to local state, there is no need for a version check at
all, as we cannot break the Terraform Cloud workspace. When migrating
to Terraform Cloud, we should use the more forgiving check, rather than
the strict equality.

This commit fixes both of these cases accordingly, and allows migrating
state to and from Terraform Cloud remote workspaces without errors.

Martin Atkins e865faf318 command: Better visual hierarchy for diagnostics
I frequently see people attempting to ask questions about Terraform's
error and warning messages but either only copying part of the message or
accidentally copying a surrounding paragraph that isn't part of the
message.

While I'm sure some of these are just "careless" mistakes, I've also
noticed that this has sometimes overlapped with someone asking a question
whose answer is written directly in the part of the message they didn't
include when copying, and so I have a theory that our current output
doesn't create a good enough visual hierarchy for sighted users to
understand where the diagnostic messages start and end when we show them
in close proximity to other content, or to other diagnostic messages.
As a result, some folks fail to notice the relevant message that might've
answered their question.

I tried a few different experiments for different approaches here, such
as adding more horizontal rules to the output and coloring the detail
text differently, but the approach that felt like the nicest compromise
to me was what's implemented here, which is to add a vertical line
along the left edge of each diagnostic message, colored to match with the
typical color we use for each diagnostic severity. This means that the
diagnostics end up slightly indented from what's around them, and the
vertical line seems to help subtly signal how we intended the content
to be grouped together.

Martin Atkins 1f1af87dea command/format: Don't try to fill the last terminal column
In some terminal emulators, writing a character into the last column on a
row causes the terminal to immediately wrap to the beginning of the next
line, even if the very next character in the stream is a hard newline.
That can then lead to errant blank lines in the final output which make
it harder to navigate the visual hierarchy.

As a compromise to avoid this, we'll format our horizontal rules and
paragraphs to one column less than the terminal width. That does mean that
our horizontal rules won't _quite_ cover the whole terminal width, but
it seems like a good compromise in order to get consistent behavior across
a wider variety of terminal implementations.

Martin Atkins 0c84a56700 command/format: Use box drawing chars for rules in diagnostics
We were previously using some ASCII art to create some visual divisions

2021-01-13 15:37:04 -08:00
Martin Atkins e6a516d87e backend/local: Use terminal properties to tweak the plan output
We now require the output to accept UTF-8 and we can determine how wide
the terminal (if any) is, so here we begin to make use of that for the
"terraform plan" command.

The horizontal rule is now made of box drawing characters instead of
hyphens and fills the whole terminal width.

The paragraphs of text in the output are now also wrapped to fill the
terminal width, instead of the hard-wrapping we did before.

This is just a start down the road of making better use of the terminal
capabilities. Lots of other commands could benefit from updates like these
too.

Martin Atkins d2c3403ab6 command: Use the new terminal.Streams object
Here we propagate in the initialized terminal.Streams from package main,
and then onwards to backends running in CLI mode.

This also replaces our use of helper/wrappedstreams to determine whether
stdin is a terminal or a pipe. helper/wrappedstreams returns incorrect
file descriptors on Windows, causing StdinPiped to always return false on
that platform and thus causing one of the odd behaviors discussed in

Finally, this includes some wrappers around the ability to look up the
number of columns in the terminal in preparation for use elsewhere. These
wrappers deal with the fact that our unit tests typically won't populate
meta.Streams.

command/state list: list resources in nested and expanded modules (#27268)
* command/state list: list resources in nested and expaneded modules

A few distinct bugs fixed in here:

There was a bug in the logic checking if a given module was the child of
the targetAddr, now fixed. That resolved the basic issue where resources
in nested submodules were not listed.

The logic around allowMissing needed some tweaking to allow for empty
modules, as long as those modules had submodules with resources. state
list is the only command using allowMissing with false so this felt safe
to do.

Finally I extended the logic so list would included expanded modules,
which is to say giving module.foo would result in resources from
module.foo[1], module.foo[0], etc.

* update state list docs to show that module filtering includes any nested
modules

console: normalize module path before building context (#27263)
Expressions such as "path.root" were returning the cwd (or modulePath),
instead of the usual _relative_ path. This commit normalizes the path
before building the context.

Alisdair McDiarmid f1b95788b9 command: Add tests for terraform validate -json
Also uncomment and fix some tests which had been skipped for a couple of
years. Those validate cases work now!

Note that these test cases and the JSON output are not especially
minimized, making them snapshot/golden tests. The output looks correct
at time of writing, and we don't expect to change validate significantly
any time soon, but if we do there will be some churn here.

Martin Atkins bab4979128 command/init: Remove the warnings about the "legacy" cache directory
We included these warnings in v0.14 after noticing that we'd accidentally
published some incorrect documentation about the purpose of the plugin
cache directory under .terraform/plugins. We switched to using
.terraform/providers instead so that we could treat any missing providers
that appear in the legacy directory as likely to be a result of following
that documentation, and thus produce this extra warning.

However, the further we get from v0.13 the more likely it is for this
warning to be a confusing false positive rather than something helpful,
and this is a non-trivial codepath requiring us to retain a concept that
we otherwise don't need (the "legacy cache dir"), so here we'll remove
those warnings and support code for v0.15 onwards.

These warnings were always accompanied by an error message saying that a
provider could not be found, and that error message remains after this
change. This just removes the "by the way..."-style warning we had been
emitting alongside the errors.

Martin Atkins 4b3e237668 command/init: Hint about providers in other namespaces
If a user forgets to specify the source address for a provider, Terraform
will assume they meant a provider in the registry.terraform.io/hashicorp/
namespace. If that ultimately doesn't exist, we'll now try to see if
there's some other provider source address recorded in the registry's
legacy provider lookup table, and suggest it if so.

The error message here is a terse one addressed primarily to folks who are
already somewhat familiar with provider source addresses and how to
specify them. Terraform v0.13 had a more elaborate version of this error
message which directed the user to try the v0.13 automatic upgrade tool,
but we no longer have that available in v0.14 and later so the user must
make the fix themselves.

Alisdair McDiarmid 4b9dada877 command: Revert local patch for pkg/browser
The upstream bug with opening a browser on Windows Subsystem for Linux
has been fixed, so this reverts our local patch for this. The approach
upstream adds fallback support for x-www-browser and www-browser if
xdg-open fails, and this fixes the problem on WSL.

This reverts commit 12e090ce48.

Martin Atkins 3268a7eaba command/output: Raw output mode
So far the output command has had a default output format intended for
human consumption and a JSON output format intended for machine
consumption.

However, until Terraform v0.14 the default output format for primitive
types happened to be _almost_ a raw string representation of the value,
and so users started using that as a more convenient way to access
primitive-typed output values from shell scripts, avoiding the need to
also use a tool like "jq" to decode the JSON.

Recognizing that primitive-typed output values are common and that
processing them with shell scripts is common, this commit introduces a new
-raw mode which is explicitly intended for that use-case, guaranteeing
that the result will always be the direct result of a string conversion
of the output value, or an error if no such conversion is possible.

Our policy elsewhere in Terraform is that we always use JSON for
machine-readable output. We adopted that policy because our other
machine-readable output has typically been complex data structures rather
than single primitive values. A special mode seems justified for output
values because it is common for root module output values to be just
strings, and so it's pragmatic to offer access to the raw value directly
rather than requiring a round-trip through JSON.

Pam Selle b963ea8594 Update docs and add warning for -get-plugins
As of Terraform 0.13+, the get-plugins command has been
superceded by new provider installation mechanisms, and
general philosophy (providers are always installed, but
the sources may be customized). Updat the init command
to give users a warning if they are setting this flag,
to encourage them to remove it from their workflow, and
update relevant docs and docstrings as well

command/format: concise diff is now the default (#27079)
* command/format: concise diff is no longer an experiment

Since state formatting goes through the "diff" printer, I have
repurposed the concise flag as a verbose flag, used only when printing
state. It's silly but it works!

* remove helper/experiment
With this experiment concluded, we no longer need helper/experiment. The
shadow experiment had not been touched in many years, so I removed all
references, and removed the package entirely. Any new experiments are
expected to be configuration experiments handled by our (other)
experiments package.

* check for the verbose flag consistently, in case we end up using it in plans in the future

Martin Atkins 0a596d2a12 command/version: Report the current platform
Along with all of the other information we previously reported in the
"terraform version" output, we'll now include the name of the current
platform as our provider mechanisms represent it.

This is addressing a long-standing minor annoyance where we often can't
tell from an incomplete bug report which platform Terraform was running
on, and incomplete bug reporters do tend to at least include the
"terraform version" output even if they don't also include the requested
full trace log.

However, what motivated doing it _now_ is that anyone building a provider
registry or mirror needs to have some awareness of these platform
identifiers which have been, until v0.13, mostly an implementation detail.
This additional information is a small thing we can do to help registry
builders find out what the platform identifier ought to be for each of
the platforms they aim to support, even if some of them are platforms
which the Go compiler allows but which HashiCorp doesn't officially
support.

The new information is on a line of its own in the output as a pragmatic
way to avoid breaking anyone who might be using something like
$(terraform version | head -n1) to print a brief Terraform version
identifier into some logs. That's not an interface we officially support
for machine consumption, but it's easy to avoid breaking it here and so we
won't do so.

Alisdair McDiarmid c5c1f31db3 backend: Validate remote backend Terraform version
When using the enhanced remote backend, a subset of all Terraform
operations are supported. Of these, only plan and apply can be executed
on the remote infrastructure (e.g. Terraform Cloud). Other operations
run locally and use the remote backend for state storage.

This causes problems when the local version of Terraform does not match
the configured version from the remote workspace. If the two versions
are incompatible, an `import` or `state mv` operation can cause the
remote workspace to be unusable until a manual fix is applied.

To prevent this from happening accidentally, this commit introduces a
check that the local Terraform version and the configured remote
workspace Terraform version are compatible. This check is skipped for
commands which do not write state, and can also be disabled by the use
of a new command-line flag, `-ignore-remote-version`.

Terraform version compatibility is defined as:

- For all releases before 0.14.0, local must exactly equal remote, as
  two different versions cannot share state;
- 0.14.0 to 1.0.x are compatible, as we will not change the state
  version number until at least Terraform 1.1.0;
- Versions after 1.1.0 must have the same major and minor versions, as
  we will not change the state version number in a patch release.

If the two versions are incompatible, a diagnostic is displayed,
advising that the error can be suppressed with `-ignore-remote-version`.
When this flag is used, the diagnostic is still displayed, but as a
warning instead of an error.

Commands which will not write state can assert this fact by calling the
helper `meta.ignoreRemoteBackendVersionConflict`, which will disable the
checks. Those which can write state should instead call the helper
`meta.remoteBackendVersionCheck`, which will return diagnostics for
display.

In addition to these explicit paths for managing the version check, we
have an implicit check in the remote backend's state manager
initialization method. Both of the above helpers will disable this
check. This fallback is in place to ensure that future code paths which
access state cannot accidentally skip the remote version check.
