Chris Marchesi 9625830980 helper/schema: Move computedKeys init to init function
This simplifies the new value initialization and future-proofs it
against more complex initialization functionality.

Chris Marchesi 3444549d60 helper/schema: Move computed key reader logic to childAddrOf
This will make this check safer and will remove the risk of it passing
on keys with a similar prefix.

Chris Marchesi 36aa63b338 helper/schema: Guard against out of range on childAddrOf
This could panic if we sent a parent that was actually longer than the
child (should almost never come up, but the guard will make it safe
anyway).

Also fixed a slice style lint warning in UpdatedKeys.

Chris Marchesi 931b0e1441 helper/schema: Remove exported SetDiff method
The consensus is that it's a generally better idea to move setting the
functionality of old values completely to the refresh/read process,
hence it's moot to have this function around anymore. This also means we
don't need the old value reader/writer anymore, which simplifies things.

Chris Marchesi ad98471559 helper/schema: Correct some comments
Removed some outdated comments for SetNew, and normalized the computed
key note for SetNew, SetNewComputed, and SetDiff.

Chris Marchesi 7d5f9ed6b1 helper/schema: NewComputed values should be nil
When working on this initially, I think I thought that since NewComputed
values in the diff were empty strings, that it was using the zero value.
After review, it doesn't seem like this is the case - so I have adjusted
NewComputed to pass nil values. There is also a guard now that keeps the
new value writer from accepting computed fields with non-nil values.

Chris Marchesi c6647a3bb7 helper/schema: CustomizeDiff -> Review
To keep with the current convention of most other schema.Resource
functional fields being fairly short, CustomizeDiff has been changed to
"Review". It would be "Diff", however it is already used by existing
functions in schema.Provider and schema.Resource.
2017-11-01 14:25:32 -07:00
Chris Marchesi f7e42728b6 helper/schema: Remove unused Destroy check for CustomizeDiff
Both Destroy and DestroyDeposed are not propagated down the diff stack,
meaning that there is no way we can tell at this point if an instance is
being destroyed or deposed, so this check would never be used.

In this regard, Destroy never runs a diff down the stack at all, and a
deposition check is not run until *after* the provider's diff function
is called. To answer this question and close it off, we could either
determine if a resource is deposed earlier, and propagate that down, or
treat deposed resources like full destroy nodes, and not diff them at
all (but rather making a diff with the only thing in it being
DestroyDeposed flagged).

Chris Marchesi fa1fc2ca8e helper/schema: CustomizeDiff invocation test
Just one more test to check to make sure that CustomizeDiff is called
on resource level.

Chris Marchesi ee769188d7 helper/schema: More CustomizeDiff test cases
Added a few more test cases for CustomizeDiff, caught another error in
the process. I think this is ready for review now, and possibly some
real-world testing of the waters by way of porting some resources that
would benefit from the feature.

Chris Marchesi 8af9610b87 helper/schema: Hook CustomizeDiffFunc into diff logic
It's alive! CustomizeDiff logic now has been inserted into the diff
process. The test_resource_with_custom_diff resource provides some basic
testing and a reference implementation.

There should now be plenty of test coverage for this feature via the
tests added for ResourceDiff, and the basic test added to the
schemaMap.Diff test, and the test resource, but more can be added to
test any specific case that comes up otherwise.

Chris Marchesi 196d7e63fe helper/schema: Drop ClearAll from ResourceDiff
As the interface has been specced out for ResourceDiff, the only diff
operation that can function on a non-computed key is ForceNew, and that
is only if a diff exists for that key. As such, allowing the user to
clear keys that cannot be operated on afterwards does not really make
much sense.

Will re-add this function if it is determined it's needed after all on
review.

Chris Marchesi 22220fd0f7 helper/schema: Final set of ResourceDiff tests, bug fixes
Final set of coverage for ResourceDiff and bug fixes to correct issues
the test cases brought up.

Will be dropping ClearAll in next commit, as with how this interface is
intended to be used, it does not really make much sense.

Chris Marchesi a5fc664ea6 helper/schema: Add schemaMap.DeepCopy
This provides a deep copy of a schemaMap, which will be needed for the
diff customization process as ResourceDiff will be able to flag fields
as ForceNew - we don't want to affect the source schema.

Chris Marchesi 6a4f7b0dce helper/schema: Don't ignore diffs for certain NewComputed keys
In diffString, removed values are marked if the old value is non-nil and
the new value is nil, regardless of if the new value is marked as a
computed value. With the new diff override behaviour, this can lead to
issues where a nil attribute may get inserted into the diff if the new
value has been marked as computed (as the value will be marked as
missing, but computed).

This propagates into finalizeDiff in some respects because even if
NewComputed is manually set in the diff that gets passed in, it is
ignored, and the schema becomes the only source of truth. Since our new
diff behaviour is mainly designed to be supported on computed keys only,
it stands to reason that we there will be a time where we want to set a
diff as NewComputed on a key, and see that change in the diff.

These two small changes makes that happen. No regressions in tests have
been observed via this change, so it seems safe and non-invasive.

Chris Marchesi 64cc4084d2 helper/schema: ResourceDiff tests, bug fixes
The beginning of tests for SetNew. Noticed that removed values are not
logged for computed keys in a diff - not too sure if that is going to be
a problem (possibly not as GetChange in ResourceData should still
reference state for the old value). I came on this most notably in the
"TestSetNew/complex-ish_set_diff" test, for reference.

More tests pending for other functions for coverage of other functions
and test cases as defined in #8769.

Chris Marchesi f5f4e0329f helper/schema: Track updated keys in ResourceDiff
This ensures that when we hook this into the main diff logic, that we
can just re-diff the keys that are modified, ensuring that the diff is
not re-run on keys that were not touched, or on keys that were
intentionally removed.
2017-11-01 14:25:32 -07:00
Chris Marchesi aeb793f968 helper/schema: Add Clear function to ResourceDiff
This should complete the feature set of the prototype. This function
removes a specific key from the existing diff, preventing conflicts.

Further functionality might be needed to make this behave as expected,
namely ensuring that we don't re-process the whole diff after the
CustomizeDiffFunc runs.

Chris Marchesi 1e8cfc52e9 helper/schema: Updated ResourceDiff prototype
This new prototype removes the dependence on a underlying ResourceData,
moving several items up to ensure an approach that more matches
ResourceData. Namely, we create our own MultiLevelFieldReader that
also layers updated diff values on top. New values use a small
re-implementation of the MapFieldWriter/Reader that allows computed
values to be set.

The assumption here now is that a second diff will happen after the
first one is done, processing the new values set in the 2 new
reader/writer levels and updating the diff as necessary.

Chris Marchesi b99c615ee6 helper/schema: New ResourceDiff object
This adds a new object, ResourceDiff, to the schema package. This
object, in conjunction with a function defined in CustomizeDiff in the
resource schema, allows for the in-flight customization of a Terraform
diff. This helps support use cases such as when there are necessary
changes to a resource that cannot be detected in config, such as via
computed fields (most of the utility in this object works on computed
fields only). It also allows for a wholesale wipe of the diff to allow
for diff logic completely offloaded to an external API, if it is a
better use case for a specific provider.

As part of this work, many internal diff functions have been moved to
use a special resourceDiffer interface, to allow for shared
functionality between ResourceDiff and ResourceData. This may be
extended to the DiffSuppressFunc as well which would restrict use of
ResourceData in DiffSuppressFunc to generally read-only fields.

This work is not yet in its final state - CustomizeDiff is not yet
implemented in the general diff workflow, new functions may be added
(notably Clear() for a single key), and functionality may be altered.
Tests will follow as well.

Martin Atkins 505683dcd3 config/module: produce explicit error for non-registry hosts
If registry API discovery fails for a particular host then it's better to
generate an explicit error message for that early -- so we can tell the
user exactly what happened -- rather than assuming a default path and
then failing downstream when we get a 404 from that request.

Martin Atkins 7fa731f293 website: Modules Getting Started guide to use Terraform Registry
This is a significant rework of the Modules getting started guide to be
in terms of the Consul module available via the Terraform Registry. This
allows us to introduce the registry as part of the tutorial, and also
gives us some auto-generated documentation to link to as context for
the tutorial.

This new module is designed pretty differently than the one we formerly
used, and in particular it doesn't expose any server addresses for the
created Consul cluster -- due to using an auto-scaling group -- and thus
we're forced to use the (arguably-less-compelling) auto-scaling group name
for our output example.

Martin Atkins 91a4af9c8a website: rewrite modules usage documentation for new features
The modules mechanism has changed quite a bit for version 0.11 and so
although simple usage remains broadly compatible there are some
significant changes in the behavior of more complex modules.

Since large parts of this were rewritten anyway, I also took the
opportunity to do some copy-editing to make the prose on this page more
consistent with our usual editorial voice and to wrap the long
lines.

Update CHANGELOG.md 2017-11-01 06:58:16 -07:00
Martin Atkins 400038eda4 command: "terraform apply" uses interactive confirmation by default
In the 0.10 release we added an opt-in mode where Terraform would prompt
interactively for confirmation during apply. We made this opt-in to give
those who wrap Terraform in automation some time to update their scripts
to explicitly opt out of this behavior where appropriate.

Here we switch the default so that a "terraform apply" with no arguments
will -- if it computes a non-empty diff -- display the diff and wait for
the user to type "yes" in similar vein to the "terraform destroy" command.

This makes the commonly-used "terraform apply" a safe workflow for
interactive use, so "terraform plan" is now mainly for use in automation
where a separate planning step is used. The apply command remains
non-interactive when given an explicit plan file.

The previous behavior -- though not recommended -- can be obtained by
explicitly setting the -auto-approve option on the apply command line,
and indeed that is how all of the tests are updated here so that they can
continue to run non-interactively.

James Bardin 6cb4e14cf8 Use pooled http client for fetching providers
While the TLS handshakes are a fairly small overhead compared to
downloading the providers, clients in some situation are failing to
complete the TLS handshake in a timely manner. It's unclear if this is
because of heavily constrained clients are stalling while doing the
major crpto operations, or the edge servers are throttling repeated
requests from the same IPs.

This should allow reusing the open TLS connection to the release edge
servers during init.

Martin Atkins 288f7c00e4 config/module: allow registry download sources to be relative paths
It's not always easy or convenient for a web application to determine its
own absolute URL to return, so here we pragmatically allow the download
source string from a registry to be a path relative to the download
endpoint.

Since X-Terraform-Get is a go-getter string, not all valid values are
valid URLs and so we sniff for certain relative-path-looking prefixes
in order to decide whether to apply the relative lookup transform.
