Core was previously ignoring JSON-encoded dynamic values, but these are
technically supported, so we must either error or accept the value.
Since we already have the decoder for Json state, it's minimal effort to
support this on all plugin methods too.
This change also gives providers an easy way to implement the
UpgradeResourceState method. The obvious implementation of returning the same
JSON-encoded value has tripped up a few providers not using the legacy
SDK already, and we should have at least indicated that the value was
being lost.
A cost estimation error does not actually stop a run, so the run was continuing in the background after the cli exits, causing confusion. This change matches the UI behavior.
For normal provider installation we want to associate each provider with
a selected version number and find a suitable package for that version
that conforms to the official hashes for that release.
Those requirements are very onerous for a provider developer currently
testing a not-yet-released build, though. To allow for that case this new
CLI configuration feature allows overriding specific providers to refer
to give local filesystem directories.
Any provider overridden in this way is not subject to the usual
restrictions about selected versions or checksum conformance, and
activating an override won't cause any changes to the selections recorded
in the lock file because it's intended to be a temporary setting for one
developer only.
This is, in a sense, a spiritual successor of an old capability we had to
override specific plugins in the CLI configuration file. There were
some vestiges of that left in the main package and CLI config package
but nothing has actually been honoring them for several versions now and
so this commit removes them to avoid confusion with the new mechanism.

If the provisioner configuration includes sensitive values, it's a
reasonable assumption that we should suppress its log output. Obvious
examples where this makes sense include echoing a secret to a file using
local-exec or remote-exec.
This commit adds tests for both logging output from provisioners with
non-sensitive configuration, and suppressing logs for provisioners with
sensitive values in configuration.
Note that we do not suppress logs if connection info contains sensitive
information, as provisioners should not be logging connection
information under any circumstances.
If provisioner configuration or connection info includes sensitive
values, we need to unmark them before calling the provisioner. Failing
to do so causes serialization to error.
Unlike resources, we do not need to capture marked paths here, so we
just discard the marks.
If a NestingList or NestingMap contains a dynamic type, they must be
handled as a cty.Tuple and cty.Object respectively, because the elements
may not have precisely matching types.
In this case, "atomic" means that there will be no situation where the
file contains only part of the newContent data, and therefore other
software monitoring the file for changes (using a mechanism like inotify)
won't encounter a truncated file.
It does _not_ mean that there can't be existing filehandles open against
the old version of the file. On Windows systems the write will fail in
that case, but on Unix systems the write will typically succeed but leave
the existing filehandles still pointing at the old version of the file.
They'll need to reopen the file in order to see the new content.
This originated in the cliconfig code to write out credentials files. The
Windows implementation of this in particular was quite onerous to get
right because it needs a very specific sequence of operations to avoid
running into exclusive file locks, and so by factoring this out with
only cosmetic modification we can avoid repeating all of that engineering
effort for other atomic file writing use-cases.
