This package aims to encapsulate the module/resource repetition problem
so that Terraform Core's graph node DynamicExpand implementations can be
simpler.
This is also a building block on the path towards module repetition, by
modelling the recursive expansion of modules and their contents. This will
allow the Terraform Core plan graph to have one node per configuration
construct, each of which will DynamicExpand into as many sub-nodes as
necessary to cover all of the recursive module instantiations.
For the moment this is just dead code, because Terraform Core isn't yet
updated to use it.
When ModuleInstanceStep values appear alone in debug messages, it's easier
to read them in a compact, HCL-like form than as the default struct
printing style.
If an error occurs on creating the context for console or import, we
would fail to unlock the state. Fix this by unlocking slightly earlier.
Affects console and import commands.
Fixes#23318
* fix outdated syntax in comments
* test for non-strings in ParseAbsProviderConfig
* ProviderConfigDefault and ProviderConfigAliased now take Providers
instead of strings
If the resource was stored as CreateBeforeDestroy, use the same ordering
regardless.
This reversal will be taken care if more cleanly in state-only destroys,
and with less risk. Don't use this commit as-is.
If the Diff is only a delete action, we can't override
CreateBeforeDestroy, because it will always be false and prevent the
stored state value from being used.
We no longer need special cases for most things during a full destroy,
so remove those from the graph transformations.
The only remaining cases are:
- remove the root outputs, so destroy ends up with a clean state
- reverse the target deps when targeting a destroy.
Remove all the destroy provisioner tests that are testing what is no
longer allowed.
Add missing state dependencies to remaining tests that require it.
The AttachStateTransformer was never run in the destroy plan. This means
that resource without configuration that used a non-default provider
would not be connected to the correct provider for the plan.
The test that was attempting to catch this only worked because the
temporary graph used in the DestroyEdgeTransformer would add the state
and detect some issues.
Start by removing the DestroyEdge type altogether. This is only used to
detect the natural edge between a resource's create and destroy nodes,
but that's not necessary for any transformations. The custom edge type
also interferes with normal graph manipulations, because you can't
delete an arbitrary edge without knowing the type, so deletion of the
edge based only on the endpoints is often done incorrectly. The dag
package itself does this incorrectly in TransitiveReduction, which
always assumes the BasicEdge type.
Now that inter-resource destroy dependencies are already connected in the
DestroyEdgeTransformer (from the stored deps in state), there's no need
to search out all dependant resources in the CBD transformation, as they
should all be connected. This makes the CBD transformation rule quite
simple: reverse any edges from create nodes.
This special edge type is no longer used. While we still have the option
of encoding more meaning into the edged themselves, having one special
edge type used only in one specific case was easily overlooked, as
dag.BasicEdge is assumed in all other cases.
The requires destroy dependencies are what is stored in the state, and
have already been connected. There is no need to search further, since
new nodes from the config may interfere with the original destroy
ordering.
a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings).
The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN. This is fine for now as we are only working with default assumption.
With the current implementation of terraform login, Windows Subsystem
for Linux fails to open a browser due to lack of support for xdg-open.
This commit reuses a fix from pkg/browser#8 which detects a WSL
environment and uses cmd.exe to open the URL instead.
* add TencentCloud COS backend for remote state
* add vendor of dependence
* fixed error not handle and remove default value for prefix argument
* get appid from TF_COS_APPID environment variables
