Martin Atkins a43b7df282 core: Handle forced-create_before_destroy during the plan walk
Previously we used a single plan action "Replace" to represent both the
destroy-before-create and the create-before-destroy variants of replacing.
However, this forces the apply graph builder to jump through a lot of
hoops to figure out which nodes need it forced on and rebuild parts of
the graph to represent that.

If we instead decide between these two cases at plan time, the actual
determination of it is more straightforward because each resource is
represented by only one node in the plan graph, and then we can ensure
we put the right nodes in the graph during DiffTransformer and thus avoid
the logic for dealing with deposed instances being spread across various
different transformers and node types.

As a nice side-effect, this also allows us to show the difference between
destroy-then-create and create-then-destroy in the rendered diff in the
CLI, although this change doesn't fully implement that yet.

Martin Atkins 5390fb1eed backend/local: Don't count outputs for choosing diff action symbols
We're not yet showing outputs in the rendered diff, so it doesn't make
sense to count them for the purpose of deciding which change action
symbols to include in the legend.

Martin Atkins 239a54ad6f command: initial structural diff rendering
This is a light adaptation of our earlier prototype of structural diff
rendering, as a starting point for what we'll actually ship. This is not
consistent with the latest mocks, so will need some additional work before
it is ready, but integrating this allows us to at least see the plan
contents while fixing up remaining issues elsewhere.

Martin Atkins a3403f2766 terraform: Ugly huge change to weave in new State and Plan types
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.

The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.

The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.

Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.

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

Martin Atkins c937c06a03 terraform: ugly huge change to weave in new HCL2-oriented types
Due to how deeply the configuration types go into Terraform Core, there
isn't a great way to switch out to HCL2 gradually. As a consequence, this
huge commit gets us from the old state to a _compilable_ new state, but
does not yet attempt to fix any tests and has a number of known missing
parts and bugs. We will continue to iterate on this in forthcoming
commits, heading back towards passing tests and making Terraform
fully-functional again.

The three main goals here are:
- Use the configuration models from the "configs" package instead of the
  older models in the "config" package, which is now deprecated and
  preserved only to help us write our migration tool.
- Do expression inspection and evaluation using the functionality of the
  new "lang" package, instead of the Interpolator type and related
  functionality in the main "terraform" package.
- Represent addresses of various objects using types in the addrs package,
  rather than hand-constructed strings. This is not critical to support
  the above, but was a big help during the implementation of these other
  points since it made it much more explicit what kind of address is
  expected in each context.

Since our new packages are built to accommodate some future planned
features that are not yet implemented (e.g. the "for_each" argument on
resources, "count"/"for_each" on modules), and since there's still a fair
amount of functionality still using old-style APIs, there is a moderate
amount of shimming here to connect new assumptions with old, hopefully in
a way that makes it easier to find and eliminate these shims later.

I apologize in advance to the person who inevitably just found this huge
commit while spelunking through the commit history.

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

A lot of this is mechanical rewriting to the new API, but
meta_config.go and meta_backend.go in particular saw some major
changes to interface with the new loader APIs and to deal with
the change in order of steps in the backend API.
2018-10-16 18:44:26 -07:00
Martin Atkins 5782357c28 backend: Update interface and implementations for new config loader
The new config loader requires some steps to happen in a different
order, particularly in regard to knowing the schema in order to
decode the configuration.

Here we lean directly on the configschema package, rather than
on helper/schema.Backend as before, because it's generally
sufficient for our needs here and this prepares us for the
helper/schema package later moving out into its own repository
to seed a "plugin SDK".

At the moment we have no cache of source code, so in practice this
codepath can never be visited. Callers to format.Diagnostic will be
gradually updated in subsequent commits.

Sander van Harmelen b1fdbd7db8 Allow enhanced backends to pass custom exit codes
In some cases this is needed to keep the UX clean and to make sure any remote exit codes are passed through to the local process.

The most obvious example for this is when using the "remote" backend. This backend runs Terraform remotely and stream the output back to the local terminal.

When an error occurs during the remote execution, all the needed error information will already be in the streamed output. So if we then return an error ourselves, users will get the same errors twice.

By allowing the backend to specify the correct exit code, the UX remains the same while preserving the correct exit codes.

Sander van Harmelen 4aeb67b8ff backend/remote: handle empty results correctly
The pagination info of a list call that returns an empty list contains:

The tests are updated so they will fail (timeout after 1m) if this is handled incorreclty.

Fix drift caused from gofmt when running make dev and go 1.11.
A fresh checkout of `origin/master` does not build atm using the `dev`
target because `master` has not been formatted using `gofmt` from Go
1.11 (tis has been the case for a while if you've been running devel).

None of the drift in question is especially new but now that Go 1.11
has been released and gofmt's formatting guidelines have been updated,
it would be *really* nice if the code in `master` reflected the current
tooling in order to avoid having to fight this drift locally.

James Bardin e9a76808df create clistate.Locker interface
Simplify the use of clistate.Lock by creating a clistate.Locker
instance, which stores the context of locking a state, to allow unlock
to be called without knowledge of how the state was locked.

This alows the backend code to bring the needed UI methods to the point
where the state is locked, and still unlock the state from an outer
scope.

Provide a NoopLocker as well, so that callers can always call Unlock
without verifying the status of the lock.

Add the StateLocker field to the backend.Operation, so that the state
lock can be carried between the different function scopes of the backend
code. This will allow the backend context to lock the state before it's
read, while allowing the different operations to unlock the state when
they complete.

James Bardin 85d6b1d9cc add test for lock error and force-unlock
This adds a general test to verify that a remote state backend returns
the expected error type when it cannot lock a state. It then extracts
the ID reported in the error, and attempts to unlock the state using
that ID, which simulated the force-unlock scenario. This is a separate
test, since not all backends have persistent locks that can be unlocked
later.

We also split out the backend test to be called individually as needed.

James Bardin ef8ed1e275 coalesce the backened interrupt code

2018-02-12 11:56:54 -05:00
James Bardin 7cba68326a always wait for a RunningOperation to return
If the user wishes to interrupt the running operation, only the first
interrupt was communicated to the operation by canceling the provided
context. A second interrupt would start the shutdown process, but not
communicate this to the running operation. This order of event could
cause partial writes of state.

What would happen is that once the command returns, the plugin system
would stop the provider processes. Once the provider processes dies, all
pending Eval operations would return return with an error, and quickly
cause the operation to complete. Since the backend code didn't know that
the process was shutting down imminently, it would continue by
attempting to write out the last known state. Under the right
conditions, the process would exit part way through the writing of the
state file.

Add Stop and Cancel CancelFuncs to the RunningOperation, to allow it to
easily differentiate between the two signals. The backend will then be
able to detect a shutdown and abort more gracefully.

In order to ensure that the backend is not in the process of writing the
state out, the command will always attempt to wait for the process to
complete after cancellation.

Laura Martin 6e1e614a56 Change -force to -auto-approve when destroying
Since an early version of Terraform, the `destroy` command has always
had the `-force` flag to allow an auto approval of the interactive
prompt. 0.11 introduced `-auto-approve` as default to `false` when using
the `apply` command.

The `-auto-approve` flag was introduced to reduce ambiguity of it's
function, but the `-force` flag was never updated for a destroy.

People often use wrappers when automating commands in Terraform, and the
inconsistency between `apply` and `destroy` means that additional logic
must be added to the wrappers to do similar functions. Both commands are
more or less able to run with similar syntax, and also heavily share
their code.

This commit updates the command in `destroy` to use the `-auto-approve` flag
making working with the Terraform CLI a more consistent experience.

We leave in `-force` in `destroy` for the time-being and flag it as
deprecated to ensure a safe switchover period.

stack72 1fd0f803e4 Migrate Manta Remote state to be a backend
This PR changes manta from being a legacy remote state client to a new backend type. This also includes creating a simple lock within manta

This PR also unifies the way the triton client is configured (the schema) and also uses the same env vars to set the backend up

It is important to note that if the remote state path does not exist, then the backend will create that path. This means the user doesn't need to fall into a chicken and egg situation of creating the directory in advance before interacting with it

Martin Atkins 671aace8ec backend/local: disable local backup of remote state
Previously we forced all remote state backends to be wrapped in a
BackupState wrapper that generates a local "terraform.tfstate.backup"
file before updating the remote state.

This backup mechanism was motivated by allowing users to recover a
previous state if user error caused an undesirable change such as loss
of the record of one or more resources. However, it also has the downside
of flushing a possibly-sensitive state to local disk in a location where
users may not realize its purpose and accidentally check it into version
control. Those using remote state would generally prefer that state never
be flushed to local disk at all.

The use-case of recovering older states can be dealt with for remote
backends by selecting a backend that has preservation of older versions
as a first-class feature, such as S3 versioning or Terraform Enterprise's
first-class historical state versioning mechanism.

There remains still one case where state can be flushed to local disk: if
a write to the remote backend fails during "terraform apply" then we will
still create the "errored.tfstate" file to allow the user to recover. This
seems like a reasonable compromise because this is done only in an
_exceptional_ case, and the console output makes it very clear that this
file has been created.

Fixes #15339.

Martin Atkins 0fe43c8977 cli: allow disabling "next steps" message in terraform plan
In #15884 we adjusted the plan output to give an explicit command to run
to apply a plan, whereas before this command was just alluded to in the
prose.

Since releasing that, we've got good feedback that it's confusing to
include such instructions when Terraform is running in a workflow
automation tool, because such tools usually abstract away exactly what
commands are run and require users to take different actions to
proceed through the workflow.

To accommodate such environments while retaining helpful messages for
normal CLI usage, here we introduce a new environment variable
TF_IN_AUTOMATION which, when set to a non-empty value, is a hint to
Terraform that it isn't being run in an interactive command shell and
it should thus tone down the "next steps" messaging.

The documentation for this setting is included as part of the "...in
automation" guide since it's not generally useful in other cases. We also
intentionally disclaim comprehensive support for this since we want to
avoid creating an extreme number of "if running in automation..."
codepaths that would increase the testing matrix and hurt maintainability.

The focus is specifically on the output of the three commands we give in
the automation guide, which at present means the following two situations:

* "terraform init" does not include the final paragraphs that suggest
  running "terraform plan" and tell you in what situations you might need
  to re-run "terraform init".
* "terraform plan" does not include the final paragraphs that either
  warn about not specifying "-out=..." or instruct to run
  "terraform apply" with the generated plan file.

Martin Atkins 83414beb8f command: various adjustments to the diff presentation
The previous diff presentation was rather "wordy", and not very friendly
to those who can't see color either because they have color-blindness or
because they don't have a color-supporting terminal.

This new presentation uses the actual symbols used in the plan output
and tries to be more concise. It also uses some framing characters to
try to separate the different stages of "terraform plan" to make it
easier to visually navigate.

The apply command also adopts this new plan presentation, in preparation
for "terraform apply" (with interactive plan confirmation) becoming the
primary, safe workflow in the next major release.

Finally, we standardize on the terminology "perform" and "actions" rather
than "execute" and "changes" to reflect the fact that reading is now an
action and that isn't actually a _change_.

Martin Atkins 3ea159297c command/format: improve consistency of plan results
Previously the rendered plan output was constructed directly from the
core plan and then annotated with counts derived from the count hook.
At various places we applied little adjustments to deal with the fact that
the user-facing diff model is not identical to the internal diff model,
including the special handling of data source reads and destroys. Since
this logic was just muddled into the rendering code, it behaved
inconsistently with the tally of adds, updates and deletes.

This change reworks the plan formatter so that it happens in two stages:
- First, we produce a specialized Plan object that is tailored for use
  in the UI. This applies all the relevant logic to transform the
  physical model into the user model.
- Second, we do a straightforward visual rendering of the display-oriented
  plan object.

For the moment this is slightly overkill since there's only one rendering
path, but it does give us the benefit of letting the counts be derived
from the same data as the full detailed diff, ensuring that they'll stay
consistent.

Later we may choose to have other UIs for plans, such as a
machine-readable output intended to drive a web UI. In that case, we'd
want the web UI to consume a serialization of the _display-oriented_ plan
so that it doesn't need to re-implement all of these UI special cases.

This introduces to core a new diff action type for "refresh". Currently
this is used _only_ in the UI layer, to represent data source reads.
Later it would be good to use this type for the core diff as well, to
improve consistency, but that is left for another day to keep this change
focused on the UI.

James Bardin 76eb65c911 Fix crash in consul backend
A TLS config was being assigned to a Transport in a nil http.Client. The
Transport is built in the consul config by default, but the http.Client
is not built until later in NewClient.

Martin Atkins c12d64f340 Use t.Helper() in our test helpers
Go 1.9 adds this new function which, when called, marks the caller as
being a "helper function". Helper function stack frames are then skipped
when trying to find a line of test code to blame for a test failure, so
that the code in the main test function appears in the test failure output
rather than a line within the helper function itself.

This covers many -- but probaly not all -- of our test helpers across
various packages.

Forward-port the plan state check from the 0.9 series.
0.10 has improved the serial handling for the state, so this adds
relevant comments and some more test coverage for the case of an
incrementing serial during apply.

James Bardin bcb11f6d89 have the consul client manage the lock session
When a consul lock is lost, there is a possibility that the associated
session is still active. Most commonly, the long request to watch the
lock key may error out, while the session is continually refreshed at a
rate of TTL/2.

First have the lock monitor retry the lock internally for at least 10
seconds (5 attempts with the default 2 second wait time). In most cases
this will reconnect on the first try, keeping the lock channel open.

If the consul lock can't recover itself, then cancel the session as soon
as possible (terminating the PreiodicRenew will call Session.Destroy),
and start over. In the worse case, the consul agents were split, and the
session still exists on the leader so we may need to wait for the old
session TTL, plus the LockWait time to renew the lock.

We use a Context for the cancellation channels here, because that
removes the need to worry about double-closes and nil channels. It
requires an awkward adapter goroutine for now to convert the Done()
`<-chan` to a `chan` for PeriodicRenew, but makes the rest of the code
safer in the long run.
