Team tokens never worked with the `atlas` backend, but the `remote` backend
uses them as intended; they can perform plans and applies on workspaces where
the associated team has at least plan or write permissions, respectively.
The search "terraform leading zero" does not find the `format()`
function, which is perfectly capable of adding leading zeros.
Thus I have added this one word to help people find `format()`.
If a set element is nil in validateConfigNulls, we don't want to
append that element to the diagnostic path, since it doesn't offer any
useful info to the user.
Fix 2 specific panics in the sdk when reading nil or computed maps from
various configurations. The legacy sdk code is too dependent on undefined
behavior to attempt to find and fix the root cause at this point.
Since the code is essentially frozen for future development, these
changes are specifically targeted to only prevent panics from within
providers. Because any code effected by these changes would have
panicked, there cannot be anything depending on the behavior, and these
should be safe to fix.
The correct environment variable corresponding to the `ca_file` variable is `CONSUL_CACERT` and not `CONSUL_CAFILE`.
See `backend/remote-state/consul/backend.go` line 77.
Previously we would write to the backend for every call to PersistState,
even if nothing changed since the last write, but update the serial only
if the state had changed.
The Terraform Cloud & Enterprise state storage have a simple safety check
that any future write with an already-used lineage and serial must be
byte-for-byte identical. StatesMarshalEqual is intended to detect that,
but it only actually detects changes the state itself, and not changes
to the snapshot metadata.
Because we write the current Terraform version into the snapshot metadata
during serialization, we'd previously have an issue where if the first
state write after upgrading Terraform to a new version happened to change
nothing about the state content then we'd write a new snapshot that
differed only by Terraform version, and Terraform Cloud/Enterprise would
then reject it.
The snapshot header is discarded immediately after decoding, so we can't
use information from it when deciding whether to increment the serial.
The next best thing is to skip sending no-op snapshot updates to the state
client in the first place.
These writes are unnecessary anyway, and state storage owners have asked
us in the past to elide these to avoid generating noise in their version
logs, so we'll also finally meet those requests as a nice side-effect of
this change.
We didn't previously have tests for the full flow of retrieving and then
successively updating persisted state snapshots, so this includes a test
which covers that logic and includes an assertion that a no-op update does
not get written to the state client.
These statemgr interfaces are the new names for the older interfaces in
the "state" package. These types alias each other so it doesn't really
matter which we use, but the "state" package is deprecated and we intend
to eventually remove it, so this is a further step in that direction.
