cty now guarantees that sets of primitive values will iterate in a
reasonable order. Previously it was the caller's responsibility to deal
with that, but we invariably neglected to do so, causing inconsistent
ordering. Since cty prioritizes consistent behavior over performance, it
now imposes its own sort on set elements as part of iterating over them so
that calling applications don't have to worry so much about it.
This change also causes cty to consistently push unknown and null values
in sets to the end of iteration, where before that was undefined. This
means that our diff output will now consistently list additions before
removals when showing sets, rather than the ordering being undefined as
before.
The ordering of known, non-null, non-primitive values is still not
contractually fixed but remains consistent for a particular version of
cty.
When changes are made and we failed to upload the state, we should not
try to unlock the workspace. Leaving the workspace locked is a good
indication something went wrong and also prevents other changes from
being applied before the newest state is properly uploaded.
Additionally we now output the lock ID when a lock or force-unlock
action failed.
The grpc server does not shutdown when the listener is closed. Since
tests aren't run through go-plugin, which has a separate RPC Shutdown
channel to stop the server, we need to track and stop the server
directly.
* lang/funcs: testing of functions through the lang package API
The function-specific unit tests do not cover the HCL conversion that happens when the functions are called in a terraform configuration. For e.g., HCL converts sets to lists before passing it to the function. This means that we could not test passing a set in the function _unit_ tests.
This adds a higher-level acceptance test, plus a check that every (pure) function has a test.
* website/docs: update function documentation
* internal/initwd: Allow deprecated relative module paths
In Terraform 0.11 we deprecated this form but didn't have any explicit
warning for it. Now we'll still accept it but generate a warning. In a
future major release we will drop this form altogether, since it is
ambiguous with registry module source addresses.
This codepath is covered by the command/e2etest suite.
* e2e: Skip copying .exists file, if present
We use this only in the "empty" test fixture in order to let git know that
the directory exists. We need to skip copying it so that we can test
"terraform init -from-module=...", which expects to find an empty
directory.
* command/e2etests: Re-enable and fix up the e2etest "acctests"
We disabled all of the tests that accessed remote services like the
Terraform Registry while they were being updated to support the new
protocols we now expect. With those services now in place, we can
re-enable these tests.
Some details of exactly what output we print, etc, have intentionally
changed since these tests were last updated.
* e2e: refactor for modern states and plans
* command/e2etest: re-enable e2etests and update for tf 0.12 compatibility
plugin/discovery: mkdirAll instead of mkdir when creating cache dir
Once you start reading from stdin, that is a blocking call that will
never finish. So when a context is canceled causing the input method to
return, the read will remain blocking in the running goroutine.
There isn't a real solution for it (e.g. its not possible to unblock the
read) so the only solution is to make the reader reusable.
When rendering the diff, the NoOp changes should come from the LCS
sequence, rather than the new sequence. The two indexes will not align
in many cases, adding the wrong new object or indexing out of bounds.
The count for a data resource can potentially depend on a managed resource
that isn't recorded in the state yet, in which case references to it will
always return unknown.
Ideally we'd do the data refreshes during the plan phase as discussed in
#17034, which would avoid this problem by planning the managed resources
in the same walk, but for now we'll just skip refreshing any data
resources with an unknown count during refresh and defer that work to the
apply phase, just as we'd do if there were unknown values in the main
configuration for the data resource.
By upgrading this to a version that supports Go Modules, we can avoid
the redundant dependencies labix.org/v2/mgo and launchpad.net/gocheck.
These dependencies come via hashicorp/consul, which we have vendored for
the Consul backend.
There are no changes to the go-msgpack code here; we're just adopting a
newer version that has a go.mod present so that its dependencies can be
determined more accurately.
