Previously we relied on a constellation of coincidences for everything to
work out correctly with state serials. In particular, callers needed to
be very careful about mutating states (or not) because many different bits
of code shared pointers to the same objects.
Here we move to a model where all of the state managers always use
distinct instances of state, copied when WriteState is called. This means
that they are truly a snapshot of the state as it was at that call, even
if the caller goes on mutating the state that was passed.
We also adjust the handling of serials so that the state managers ignore
any serials in incoming states and instead just treat each Persist as
the next version after what was most recently Refreshed.
(An exception exists for when nothing has been refreshed, e.g. because
we are writing a state to a location for the first time. In that case
we _do_ trust the caller, since the given state is either a new state
or it's a copy of something we're migrating from elsewhere with its
state and lineage intact.)
The intent here is to allow the rest of Terraform to not worry about
serials and state identity, and instead just treat the state as a mutable
structure. We'll just snapshot it occasionally, when WriteState is called,
and deal with serials _only_ at persist time.
This is intended as a more robust version of #15423, which was a quick
hotfix to an issue that resulted from our previous slopping handling
of state serials but arguably makes the problem worse by depending on
an additional coincidental behavior of the local backend's apply
implementation.
Move the Swift State from a legacy remote state to an official backend.
Add `container` and `archive_container` configuration variables, and deprecate `path` and `archive_path` variables.
Future improvements: Add support for locking and environments.
* provider/openstack: Expose LogRoundTripper fields externally
* state/remote/swift: Add support for debugging Openstack calls using
OS_DEBUG env variable.
* provider/openstack: Update LogRoundTripper to log headers aswell as body.
* Add `RedactHeaders` function in order to redact sensitive http Headers.
Refactor `logRequest` and `logResponse` to use `RedactHeaders` func.
Move the S3 State from a legacy remote state to an official backend.
This increases test coverage, uses a set schema for configuration, and
will allow new backend features to be implemented for the S3 state, e.g.
"environments".
Gove LockInfo a Marshal method for easy serialization, and a String
method for more readable output.
Have the state.Locker implementations use LockError when possible to
return LockInfo and an error.
* Enable remote s3 state support for assume role
- provide role_arn in backend config to enable assume role
Fixes#8739
* Check for errors after obtaining credentials
Use a DynamoDB table to coodinate state locking in S3.
We use a simple strategy here, defining a key containing the value of
the bucket/key of the state file as the lock. If the keys exists, the
locks fails.
TODO: decide if locks should automatically be expired, or require manual
intervention.
In order to provide lockign for remote states, the Cache state,
remote.State need to expose Lock and Unlock methods. The actual locking
will be done by the remote.Client, which can implement the same
state.Locker methods.
Also fixed tests failing auth caused by getStorageAccountAccessKey returning the
key name rather than the value

- add remote state provider backed by Joyent's Manta
- add documentation of Manta remote state provider
- explicitly check for passphrase-protected SSH keys, which are currently
unsupported, and generate a more helpful error (borrowed from Packer's
solution to the same problem):
https://github.com/mitchellh/packer/blob/master/common/ssh/key.go#L27
This is a rework of pull request #6213 submitted by @joshuaspence,
adjusted to work with the remote state data source. We also add
a deprecation warning for people using the unsupported API, and retain
the ability to refer to "_local" as well as "local" for users in a mixed
version environment.
This commit enables terraform to utilise the assume role functionality
of sts to execute commands with different privileges than the API
keys specified.

Fix checksum issue with remote state
If we read a state file with "null" objects in a module and they become
initialized to an empty map the state file may be written out with empty
objects rather than "null", changing the checksum. If we can detect
this, increment the serial number to prevent a conflict in atlas.
Our fakeAtlas test server now needs to decode the state directly rather
than using the ReadState function, so as to be able to read the state
unaltered.
The terraform.State data structures have initialization spread out
throughout the package. More thoroughly initialize State during
ReadState, and add a call to init() during WriteState as another
normalization safeguard.
Expose State.init through an exported Init() method, so that a new State
can be completely realized outside of the terraform package.
Additionally, the internal init now completely walks all internal state
structures ensuring that all maps and slices are initialized. While it
was mentioned before that the `init()` methods are problematic with too
many call sites, expanding this out better exposes the entry points that
will need to be refactored later for improved concurrency handling.
The State structures had a mix of `omitempty` fields. Remove omitempty
for all maps and slices as part of this normalization process. Make
Lineage mandatory, which is now explicitly set in some tests.

* Skip IAM/STS validation and metadata check
* Skip IAM/STS identity validation - For environments or other api
implementations where there are no IAM/STS endpoints available, this
option lets you opt out from that provider initialization step.
* Skip metdata api check - For environments in which you know ahead of
time there isn't going to be a metadta api endpoint, this option lets
you opt out from that check to save time.
* Allow iam/sts initialization even if skipping account/cred validation
(#7874)
* Split out skip of IAM validation into credentials and account id
