Our prevailing writing style is to place punctuation outside of quotes, since in many contexts Terraform itself treats punctuation within quotes as significant and so it can be confusing to use punctuation in quotes in our prose.
It's becoming more common for users to have many ssh keys loaded into an
agent, and with the default max auth attempts of an openssh server at 6,
one often needs to specify which id to use in order to avoid a `too many
authentication failures` error.
Add a connection field called `agent_identity` which will function
similarly to the ssh_config IdentityFile when used in conjunction with
an ssh agent. This uses `agent_identity` rather than `identity_file` to
specify that the file is not used directly for authentication, rather
it's used to choose which identity returned from the agent to
authenticate with first.
This feature tries a number of different methods to match the agent
identity. First the provisioner attempts to read the id file and extract
the public key. If that isn't available, we look for a .pub authorized
key file. Either of these will result in a public key that can be
matched directly against the agent keys. Finally we fall back to
matching the comment string exactly, and the id as a suffix. The only
result of using the agent_identity is the reordering of the public keys
used for authentication, and if there is no exact match the client
will still attempt remaining keys until there is an error.

Rather than relying on interrupting Diff, just make sure Stop was called
on the provider. The DiffFn is protected by a mutex in the mock
provider, which means that the tests can't rely on concurent calls to
diff working.
There's no point in trying to track these, they're lost after each test.
Kill them after a short delay so we don't have goroutines from every single
command test to wade through if we have a stack dump.
The interrupt tests for providers no longer check for the condition
during the diff operation. defer the lock so other test's DiffFns don't
need to be as carefull locking themselves.
This new codepath with the getDiff "customzed" return value, along with
the associated test need to be removed as soon as we can support unset
fields from the config, so we don't continue to carry this broken
behavior forward any longer than needed.
This extends the internal diffChange method so that ResourceDiff's
implementation of it can report back whether or not the value came from
a customized diff.
This is an effort to work to preserve the pre-ResourceDiff behaviour
that ignores the diff for computed keys when the old value was populated
but the new value wasn't - this behaviour is actually being depended on
by users that are using it to exploit using zero values in modules. This
should allow both scenarios to co-exist by shifting the NewComputed
exemption over to exempting values that come from diff customization.
This reverts one of the changes from 6a4f7b0, which broke empty strings
being seen as unset for computed values.
This breaks a number of other tests, and is only an intermediate change
for evaluating other solutions.
This case should be expected to fail with the current diff algorithm,
but the existing behavior was widely relied upon so we need to roll this
back until there is a representable nil value.
Only check for input twice in the meta.confirm method. This prevents an
errant newline from aborting the run while allowing Terraform to exit if
there is no input available. We don't just check for a tty, since we
still rely on being able to pipe input in for testing.
Remove the redundant confirmation loops in the migration code, and only
use the confirm method.
Make sure the init inputFalse test actually errors from missing input,
since skipping input will still fail later during provider
initialization. We need to make sure there are two different states that
aren't a noop for migration, and reset the command struct for each run.
Also verify that we don't go into an infinite loop if there is no input.
The CustomizeDiff functionality in helper/schema is powerful, but directly
writing single CustomizeDiff functions can obscure the intent when a
number of different, orthogonal diff-customization behaviors are required.
This new library provides some building blocks that aim to allow a more
declarative form of CustomizeDiff implementation, by composing a number of
smaller operations. For example:
&schema.Resource{
// ...
CustomizeDiff: customdiff.All(
customdiff.ValidateChange("size", func (old, new, meta interface{}) error {
// If we are increasing "size" then the new value must be
// a multiple of the old value.
if new.(int) <= old.(int) {
return nil
}
if (new.(int) % old.(int)) != 0 {
return fmt.Errorf("new size value must be an integer multiple of old value %d", old.(int))
}
return nil
}),
customdiff.ForceNewIfChange("size", func (old, new, meta interface{}) bool {
// "size" can only increase in-place, so we must create a new resource
// if it is decreased.
return new.(int) < old.(int)
}),
customdiff.ComputedIf("version_id", func (d *schema.ResourceDiff, meta interface{}) bool {
// Any change to "content" causes a new "version_id" to be allocated.
return d.HasChange("content")
}),
),
}
The goal is to allow the various separate operations to be quickly seen
and to ensure that each of them runs independently of the others. These
functions all create closures on the call parameters, so the result is
still just a normal CustomizeDiffFunc and so the helpers in this package
can be combined with hand-written functions as needed.
As we get more experience writing CustomizeDiff functions we may wish to
expand the repertoire of functions here in future; this initial set
attempts to cover some common cases we've seen so far. We may also
investigate some helper functions that are entirely declarative and so
don't take callback functions at all, but want to learn what the relevant
use-cases are before going in too deep here.
The duplicate prompts can be confusing when the user confirms that a
migration should happen and we immediately prompt a second time for the
same thing with slightly different wording. The extra hand-holding that
this provides for legacy remote states is less critical now, since it's
been 2 major release cycles since those were removed.
The init command needs to parse the state to resolve providers, but
changes to the state format can cause that to fail with difficult to
understand errors. Check the terraform version during init and provide
the same error that would be returned by plan or apply.
