Previously the rendered plan output was constructed directly from the
core plan and then annotated with counts derived from the count hook.
At various places we applied little adjustments to deal with the fact that
the user-facing diff model is not identical to the internal diff model,
including the special handling of data source reads and destroys. Since
this logic was just muddled into the rendering code, it behaved
inconsistently with the tally of adds, updates and deletes.
This change reworks the plan formatter so that it happens in two stages:
- First, we produce a specialized Plan object that is tailored for use
in the UI. This applies all the relevant logic to transform the
physical model into the user model.
- Second, we do a straightforward visual rendering of the display-oriented
plan object.
For the moment this is slightly overkill since there's only one rendering
path, but it does give us the benefit of letting the counts be derived
from the same data as the full detailed diff, ensuring that they'll stay
consistent.
Later we may choose to have other UIs for plans, such as a
machine-readable output intended to drive a web UI. In that case, we'd
want the web UI to consume a serialization of the _display-oriented_ plan
so that it doesn't need to re-implement all of these UI special cases.
This introduces to core a new diff action type for "refresh". Currently
this is used _only_ in the UI layer, to represent data source reads.
Later it would be good to use this type for the core diff as well, to
improve consistency, but that is left for another day to keep this change
focused on the UI.
The implementation of ResourceAddress.Less was flawed because it was only
testing each field in the "less than" direction, and falling through in
cases where an earlier field compared greater than a later one.
Now we test for inequality first as the selector, and only fall through
if the two values for a given field are equal.
There is some additional, early validation on the "count" meta-argument
that verifies that only suitable variable types are used, and adding local
values to this whitelist was missed in the initial implementation.
It seems that this somehow got lost in the commit/rebase shuffle and
wasn't caught by the tests that _did_ make it because they were all using
just one file.
As a result of this bug, locals would fail to work correctly in any
configuration with more than one .tf file.
Along with restoring the append/merge behavior, this also reworks some of
the tests to exercise the multi-file case as better insurance against
regressions of this sort in future.
This fixes#15969.
A TLS config was being assigned to a Transport in a nil http.Client. The
Transport is built in the consul config by default, but the http.Client
is not built until later in NewClient.
In #15870 we got good feedback that it'd be more useful to have the
various filename-accepting arguments on this provisioner instead accept
strings that represent the contents of such files, so that they can be
generated from elsewhere in the Terraform config.
This change does not achieve that, but it does make room for doing this
later by renaming "minion_config" to "minion_config_file" so that we
can later add a "minion_config" option alongside that takes the file
content, and deprecate "minion_config_file".
Ideally we'd just implement the requested change immediately, but
unfortunately the release schedule doesn't have time for this so this is
a pragmatic change to allow us to make the full requested change at a
later date without backward incompatibilities.
This change is safe because the salt-masterless provisioner has not yet
been included in a release at the time of this commit.
The code here was previously assuming that d.State() was equivalent to
the schema.ProvRawStateKey due to them both being of type InstanceState,
but that is in fact not true since a state object contains some transient
information that is _not_ part of the persisted state, including the
connection information we need here.
Calling ResourceData.State() constructs a _new_ state based on its stored
values, so the constructed object is lacking this transient information.
We need to use the specific state object provided by the caller in order
to get access to the transient connection configuration.
Unfortunately there is no automated test coverage for this because we have
no good story for testing provisioners that use "communicator". While such
tests could potentially be written, we'd like to get this in somewhat
quickly to unblock a release, rather than delaying to design and implement
some sort of mocking system for this.
Previously the -upgrade option was covered only on the "terraform init" usage page. It seems also worth mentioning in the main docs on provider versioning, since we're already explaining here other mechanics of the versioning/constraints system.
Previously we were checking required_version only during "real" operations, and not during initialization. Catching it during init is better because that's the first command users run on a new working directory.
Go 1.9 adds this new function which, when called, marks the caller as
being a "helper function". Helper function stack frames are then skipped
when trying to find a line of test code to blame for a test failure, so
that the code in the main test function appears in the test failure output
rather than a line within the helper function itself.
This covers many -- but probaly not all -- of our test helpers across
various packages.
As of Go 1.9, ./... excludes the vendor directory by default and so we
no longer need to jump through hoops to exclude vendored packages from
testing, vetting, etc.
As a simplification this also re-introduces builtin/bins to the set of
packages we run tests on. With the providers now split into their own
repositories there's far fewer of these and so including them doesn't
really hurt anything, and makes our invocations here simpler.
We added the description field in 0.9 but we never parsed it because we
didn't have a use for it. As we prepare to use this field, let's start
parsing it out
Terraform modules encapsulate their resources, and dependencies can only
be expressed through outputs, which wasn't clear to me in the existing
documentation. I'm hoping a small change will make that more explicit.
The shadow graph was incredibly useful during the 0.7 cycle but these days
it is idle, since we're not planning any significant graph-related changes
for the forseeable future.
The shadow graph infrastructure is somewhat burdensome since any change
to the ResourceProvider interface must have shims written. Since we _are_
expecting changes to the ResourceProvider interface in the next few
releases, I'm calling "YAGNI" on the shadow graph support to reduce our
maintenence burden.
If we do end up wanting to use shadow graph again in future, we'll always
be able to pull it out of version control and then make whatever changes
we skipped making in the mean time, but we can avoid that cost in the
mean time while we don't have any evidence that we'll need to pay it.
Add the ValidateListUniqueStrings function, which is a ValidateFunc that
ensures a list has no duplicate items in it. It's useful for when a list
is needed over a set because order matters, yet the items still need to
be unique.
This adds a ValidateRegexp validation helper to check to see if a field
has a valid regular expression.
Includes test for good regexp, and test for bad regexp.
This is just a few editorial tweaks to the issue template.
The primary motivation here was to shorten the section about provider issues now that we're no longer in the transitional state; I suspect that this scary wall of text is dissuading people from actually reading and following the template.
Otherwise, this is just some tweaks to the wording and some adjustments for the fact that we're now not expecting provider issues here.
This escapes all characters that might have a special interpretation when embedded into a portion of a URL, including slashes, equals signs and ampersands.
