Terraform Core emits a hook event every time it writes a change into the
in-memory state. Previously the local backend would just copy that into
the transient storage of the state manager, but for most state storage
implementations that doesn't really do anything useful because it just
makes another copy of the state in memory.
We originally added this hook mechanism with the intent of making
Terraform _persist_ the state each time, but we backed that out after
finding that it was a bit too aggressive and was making the state snapshot
history much harder to use in storage systems that can preserve historical
snapshots.
However, sometimes Terraform gets killed mid-apply for whatever reason and
in our previous implementation that meant always losing that transient
state, forcing the user to edit the state manually (or use "import") to
recover a useful state.
In an attempt at finding a sweet spot between these extremes, here we
change the rule so that if an apply runs for longer than 20 seconds then
we'll try to persist the state to the backend in an update that arrives
at least 20 seconds after the first update, and then again for each
additional 20 second period as long as Terraform keeps announcing new
state snapshots.
This also introduces a special interruption mode where if the apply phase
gets interrupted by SIGINT (or equivalent) then the local backend will
try to persist the state immediately in anticipation of a
possibly-imminent SIGKILL, and will then immediately persist any
subsequent state update that arrives until the apply phase is complete.
After interruption Terraform will not start any new operations and will
instead just let any already-running operations run to completion, and so
this will persist the state once per resource instance that is able to
complete before being killed.
This does mean that now long-running applies will generate intermediate
state snapshots where they wouldn't before, but there should still be
considerably fewer snapshots than were created when we were persisting
for each individual state change. We can adjust the 20 second interval
in future commits if we find that this spot isn't as sweet as first
assumed.
The terraform provider was panicking on import, because it didn't
previously have a resource type which could be imported at all. Add a
stub import function for terraform_data as a placeholder to allow the
call to complete successfully. While there's no need to actually import
a terraform_data resource, users will inevitably use this to construct
examples of import actions for learning purposes or bug reports.
This still isn't very useful even for examples however, because the
state-only nature of the terraform_data resource type means that we
can't fill in the state from only the import ID. This means that any
value in `trigger_replace` or `input` will cause a change in the next
plan. Once configuration data is available during import we can extend
this to create a logical final state based on config.

Resource instances with no current object in state should not have
orphan nodes added to the graph, as deposed objects are handled
separately. This was previously handled correctly for the non-expanded
case, but expanded resources were missing the appropriate check for a
current object.
Also update the comment in the non-expanded case to hopefully clarify
that we're checking for the presence of a current object, not the
absence of any deposed objects. An instance may have both a current
object and zero or more deposed objects in some circumstances, and if
so, we still want an orphan node to be added if the instance is not in
configuration.
* Implementation of structured logging.
These are the changes that enable the cloud backend to consume
structured logs and make use of the new plan renderer. This will enable
CLI-driven runs to view the structured output in the Terraform Cloud UI.
* Cloud structured logging unit tests
* Remove deferred logs logic, fix minor issues
Color formatting fixes, log type stop lists, default behavior for logs
that are unknown
* Use service disco path in redacted plan url
* Add viewType to Meta object and use it at the call sites
* Assign viewType passed from flags to state-locking cli commands
* Remove temp files
* Set correct mode for statelocker depending on json flag passed to commands
* Add StateLocker interface conformation check for StateLockerJSON
* Remove empty line at end of comment
* Pass correct ViewType to StateLocker from Backend call chain
* Pass viewType to backend migration and initialization functions
* Remove json processing info in process comment
* Restore documentation style of backendMigrateOpts
This makes the behavior of remote state consistent with local state in regards to the initial serial number of the generated / pushed state. Previously remote state's initial push would have a serial number of 0, whereas local state had a serial of > 0. This causes issues with the logic around, for example, ensuring that a plan file cannot be applied if state is stale (see https://github.com/hashicorp/terraform/issues/30670 for example).

As explained by the deleted comments, this package was used to identify situations where the `terraform 0.12upgrade` command can help migrate 0.11 syntax. Current versions of terraform don't include this command, and it's not likely that users are attempting upgrades from 0.11 to 1.4+
The replacement init swaps the order of the module and backend initialization in order to prepare for the next commit.
Config initialization now takes the following approach:
1. Load the root module, but withhold diagnostic errors until after version check
2. Initialize the backend, but withhold diagnostic errors until after version check
3. Get modules
4. Load all config (root and modules)
5. Check terraform version requirements (this can be defined by nested modules) and display any errors. It's important to show these first because prior errors could be the result of a newer terraform version syntax
6. Finally, show any errors related to backed init or config loading
Although they are not serialized to the final stored state, all module
outputs must be saved in the state for evaluation. There is no defined
schema which is used to identify the overall type of module outputs, so
all outputs must exist in the state to build the correct type for proper
evaluation.
* Add mTLS support for http backend by way of client cert & key, as well as enterprise cacert.
* Fix style.
* Skip cert validation to be sure error is related to missing client cert; not untrusted server cert.
* Remove misplaced err check.
* Fix the size of test using http backend.
* Just for correctness, include all certs in the pem encoded cert - sometimes certs come with a chain of their signers.
* Adjusted names as recommended in PR comments.
* Adjusted names to be full-length and more descriptive.
* Added full-fledged testing with mTLS http server
* Fix goimports.
* Fix the names of the backend config.
* Exclusive lock for write and delete.
* Revert "Fix goimports."
This reverts commit 7d40f6099fbbb675fb2e25e35ee40aeafe3d0a22.
* goimports just for server test.
* Added the go:generation for the mock.
* Move the TLS configuration out to make it more readable - don't replace the HTTPClient as the retryablehttp already creates one - just configure its TLS.
* Just switch the client/data params - felt more natural this way.

Currently Terraform will use an entry from the global plugin cache only if
it matches a checksum already recorded in the dependency lock file. This
allows Terraform to produce a complete lock file entry on the first
encounter with a new provider, whereas using the cache in that case would
cause the lock file to only cover the single package in the cache and
thereefore be unusable on any other operating system or CPU architecture.
This temporary CLI config option is a pragmatic exception to support those
who cannot currently correctly use the dependency lock file but who still
want to benefit from the plugin cache. With this setting enabled,
Terraform has permission to produce a dependency lock file that is only
suitable for the current system if that would allow use of an existing
entry in the plugin cache.
We are introducing this option to resolve a conflict between the needs of
folks who are using the dependency lock file as expected and the needs of
folks who cannot use the dependency lock file for some reason. The hope
then is to give respite to those who need this exception in the meantime
while we understand better why they cannot use the dependency lock file
and improve its design so that everyone will be able to use it
successfully in a future version of Terraform. This option will become a
silent no-op in a future version of Terraform, once the dependency lock
file behavior is sufficient for all supported Terraform development
workflows.
The existing set comparison method uses the prior elements with the computed
portions nulled out to find candidates to match the configuration. This
has the shortcoming of always removing optional+computed attributes,
because we have not yet found the configuration to know if attribute was
set or not.
Rather than having to take the most pessimistic value before comparison
to precompute the nulled values, we can compare each candidate directly,
walking the values in tandem. Each prior value is compared against the
config and checked to see if it could have been derived from that
configuration value, which allows us to treat optional+computed as
optional if there is config and computed if there is not.
This removes the ambiguity from having optional+computed attributes
within sets, giving us consistent plans when all values are known.
Unknown values of course are still undecidable, as are edge cases were
providers refresh with altered values or retained changed prior values
plan that were deemed not functionally significant.
Unify the ProposedNew paths for Blocks and Objects. Break out the
individual case blocks into functions, then use a common interface to
dispatch the object creation to the correct function based on schema
type. This cuts the code in half, and prevents the block and object
behavior from diverging.
NestingMap structures are not well tested, and we panic in many
situations when null crops up. Fix the first test cases and start
refactoring best we can. This probably won't go so far as making all the
objchange functions generic over Block and Object, but we can simplify a
lot and verify parity in implementations for now.
