This unusual situation isn't supposed to arise in normal use, but it can
come up in practice in some edge-case scenarios where Terraform fails in
a severe way during a create_before_destroy.
Some earlier versions of Terraform also had bugs in their handling of
deposed objects, so this may also arise if upgrading from one of those
older versions with some leftover deposed objects in the state.
Added higher-level test for matchkeys to exercise mixing
types in searchset. This had to be in the functions tests so the HCL
auto conversion from tuple to list would occur.
Send Private data blob through ReadResource as well. This will allow for
extra flexibility for future providers that may want to pass data out of
band through to their resource Read functions.
Private data was previously created during Plan, and sent back to the
provider during Apply. This data also needs to be persisteded accross
Read calls, but rather than rely on core for that we can send the data
to the provider during Read to allow for more flexibilty.
`matchkeys` was returning a (false) error if the searchset was a
variable, since then the type of the keylist and searchset parameters
would not match.
This does slightly change the behavior: previously matchkeys would
produce an error if the parameters were not of the same type, for e.g.
if searchset was a list of strings and keylist was a list of integers.
This no longer produces an error.
In the unlikely event that a moduleCall has a nil config - for example,
if a nested module call includes a variable with a typo in an
attribute - continue gracefully.
This is an unusual edge case in the category of "probably should not happen", caused by
#21568
Previously, adding a version constraint to a module that was previously
recorded without a version in the module manifest would cause a panic.
Instead, we now use a slight variant of the "dependencies have changed"
error that doesn't try to print out a specific version number.
This was already working, but since that codepath is separate from the
go-getter install codepath it's helpful to have a separate test for it,
in addition to the existing one for go-getter modules.
In the unlikely event that a moduleCall has a nil config - for example,
if a nested module call includes a variable with a typo in an
attribute - continue gracefully.
* command/show -json: fix panic
afterUnknown should return only bools, not values.
* command/jsonplan: let's delete some redundant code!
the plan output was somewhat inconsistent with return values for
"after_unknown". This strives to fix that. If all "after" values are
known, return an empty object instead of iterating over values.
Also fixing some typos and general copypasta.
The config is statically validated early on for structural issues, but
the provider can't validate any inputs that were unknown at the time.
Run ValidateResourceTypeConfig during Plan, so that the provider can
validate the final config values, including those interpolated from
other resources.
Using az login and then terraform init from the command line I got `Error: Either an Access Key / SAS Token or the Resource Group for the Storage Account must be specified`
If a dynamic block is evaluated zero times, the body content will
contain 0 blocks. Allow the probe for ConfigModeAttr to accept that no
blocks with a matching attribute should still be converted to a block if
they are called with dynamicExpand.
There is currently no way to unset -backend-config during init, since
not setting that option assumes the user will use the saved config.
Allow setting `-backend-config=""` to specify no overrides.
This Vagrantfile hasn't been maintained for a long time and no longer
produces a correct and functioning development environment for Terraform.
Terraform's development environment is a pretty standard Go development
environment, so a custom VM setup for development is overkill. Maintaining
the Makefile and other similar dev environment helpers is already overhead
enough, and having this stale Vagrantfile here was occasionally causing
folks to try to use it and get frustrated that it didn't work.
The omitUnknowns and unknownAsBool functions were previously trying hard
to preserve the same collection types in the output as they had in the
input, by attempting to keep everything matched up so that the results
would be valid.
Unfortunately, this turns out to be a harder problem than we originally
thought: it was possible for a collection value going in to produce
inconsistent element types out (and thus a panic) in the following
situations:
- when a collection with mixed known and unknown values was passed in
to omitUnknowns.
- when a collection of collections where the inner collections are a
mixture of empty and not empty in unknownAsNull.
The results of these functions are only used to marshal to JSON anyway,
and JSON serialization can't distinguish between the three sequence types
or the two mapping types, so in practice we can just standardize on
converting all sequences to tuple and all mappings to object here and not
change the resulting output at all, and then we don't have to worry about
making sure all of the inner types get preserved exactly.
A nice consequence of that relaxation is that we can now do what we
originally wanted to do with unknownAsBool, and omit map keys and
object attributes altogether if their values would've been false,
producing a much more compact result. This is easiest to do now when
there's only one known user of this JSON plan output, and we know that
user will treat both false and omitted as the same here.
* core: don't panic in NodeAbstractResourceInstance References()
It is possible for s.Current to be nil. This was hard to reproduce, so
the root cause is still unknown, but we can guard against the symptom.
* add log statement
The backend gets to "prepare" the configuration before Configure is
called, in order to validate the values and insert defaults. We don't
want to store this value in the "config state", because it will often
not match the raw config after it is prepared, forcing unecessary
backend migrations during init.
Since PrepareConfig is always called before Configure, we can store the
config value directly, and assume that it will be prepared in the same
manner each time.
If the backend config hashes match during init, and there are no new
backend override options, then we assume the existing config is OK.
Since init should be idempotent, we should be able to run init with no
options or config changes, and not effect the backends at all.
