This test was incorrectly updated in a previous iteration, with it
creating a modified state to write but then not actually writing it,
writing an empty test state instead.
This made the test fail because a backup state file is created only if
the new state snapshot is different to the old when written.
Terraform used to provide empty diffs to the provider when calculating
`ignore_changes`, which would cause some DiffSuppressFunc to fail, as
can be seen in #18209.
Verify that this is no longer the case in 0.12
In order to prevent mismatched states between read/plan/apply, we need
to ensure that the attributes are generated consistently each time.
Because of the various ways in which helper/schema and the hcl2 shims
interpret empty values, the only way to ensure consistency is to always
remove them altogether.
This makes sure the diff is generated with the matching set ids from
helper/schema.
Update the tests to add ID fields to the state, which will exists in
practice, since any state traversing through the shims will have the ID
inserted.
Newer versions of the retryablehttp package use a context, so we need to
add that in our custom `CheckRetry` function.
In addition I removed the `return true, nil` to continue retrying in
case of an error, and instead directly call the `DefaultRetryPolicy`.
This is because the `DefaultRetryPolicy` will now also take the context
into consideration.
The flatmap shim was lazily adding duplicate items and letting cty.Set
clear them out, but if those duplicates contains unknown values they
can't be checked for equality and will end up remaining in the set.
Some other test is leaving behind a terraform.tfstate after it concludes,
which can cause this test to fail in a strange way due to picking up
extra provider requirements from that state.
This check doesn't fix that problem, but it at least makes the test fail
in a more helpful way to avoid time wasted trying to debug this test when
it's some other test that actually has the bug.
This test is currently failing due to the command completing successfully,
which would previously cause a panic because we didn't properly initialize
the MockUi and so its error buffer is nil unless written to.
(The failure this was masking will be fixed in a subsequent commit.)
In prior refactoring we lost the required core version check from
"terraform init", which we restore here.
Additionally, this test used to have an incorrect name that suggested it
was testing something in the "getProvider" codepath, but version checking
happens regardless of what other options are selected.
After all of the refactoring we were no longer checking the Terraform
version field in a state file, causing this test to fail.
This restores that check, though with a slightly different error message.
This test was using old-style state files as its input, differing only by
lineage. Since lineages are now managed within the state manager itself,
the test can't use that to distinguish the two files and so we put a
different output in each one instead.
This also introduces some TRACE logging to the migration codepaths.
There's some hard-to-follow control flow here and so this extra logging
helps to understand the reason for a particular outcome, and since this
codepath is visited only in "terraform init" anyway it doesn't hurt to
be a bit more verbose here.
In the refactoring for new HCL this codepath stopped taking into account
changes to the CLI -backend-config options when deciding if a backend
migration is required.
This restores that behavior in a different way than it used to be: rather
than re-hashing the merged config and comparing the hashes, we instead
just compare directly the configuration values, which must be exactly
equal in order to skip migration.
This change is covered by the test TestInit_inputFalse, although as of
this commit it is still not passing due a downstream problem within the
migration code itself.
This test was re-using the same InitCommand value to run multiple times,
which is not realistic. Since we now cache configuration source code
inside command.Meta on load, it's important that we use a fresh
InitCommand instance here so it'll see the modified configuration file
we've left on disk.
Here we were going to the trouble of copying the body so we could mutate
it, but then ended up mutating the original anyway and then returning the
unmodified copy. Whoops!
This fix is verified by a number of "init" command tests that exercise the
-backend-config option, including TestInit_backendConfigFile and several
others whose names have the prefix TestInit_backendConfig .
Since our new approach here works by installing with a synthetic module
configuration block, we need to treat relative paths as a special case
for two reasons:
- Relative paths in module addresses are relative to the file containing
the call rather than the working directory, but -from-module uses the
working directory (and the call is in a synthetic "file" anyway)
- We need to force Terraform to pass the path through to go-getter rather
than just treating it as a relative reference, since we really do want
a copy of the directory in this case, even if it is local.
To address both of these things, we'll detect a relative path and turn it
into an absolute path before beginning installation. This is a bit hacky,
but this is consistent with the general philosophy of the -from-module
implementation where it does hacky things so that the rest of the
installer code can be spared of dealing with its special cases.
This is covered by a couple of existing tests that run init -from-module,
including TestInit_fromModule_dstInSrc which now passes.
When we originally wrote this message we struggled a bit for how to refer
to the releases server without writing an awkwardly-ungrammatical
sentence, and so "the official repository" became a placeholder name for
it.
Now that we'll be looking in Terraform Registry this gives us a nice
proper noun to use. This message will need to evolve more as our
integration with the registry gets more sophisticated, but for now this
works.
Some over-zealous bulk updating of this test file caused this test to be
producing a remote state config cache file on disk when it doesn't
actually need one: the backend config comes from the plan file when
applying a saved plan.
