Since the filestate backend is now written using the go-cloud blob
abstraction, places where we were using functions from the `os`
package were very unlikely to be correct.
This change removes their uses in favor of APIs provided by
go-cloud (which sometimes requires more work than before).
For historical reasons, we used to need to require to load an existing
checkpoint to copy some data from it into the snapshot when saving a
new snapshot. The need for this was removed as part of the general
work in #2678, but we continued to load the checkpoint and then just
disregard the data that was returned (unless there was an error and
that error was not FileNotFound, in which case we would fail).
Our logic for checking if something was FileNotFound was correct when
we wrote it, but when we adopted go-cloud in order to have our
filestate backend also write to blob storage backends like S3, we
forgot that we had checks like `os.IsNotExists()` floating around
which were now incorrect. That meant if the file did not exist for
some reason, instead of going along as planned, we'd error out now
with an error saying something wasn't found.
When we write a checkpoint, we first "backed up" the initial version
by renaming it to include a `.bak` suffix, then we write the new file
in place. However, this can run afoul of eventual consistency models
like S3, since there will be a period of time in which a caller may
observe that the object is missing, even after a new version is
written (based on my understanding of [S3's consistency
model](https://docs.aws.amazon.com/AmazonS3/latest/dev/Introduction.html#ConsistencyModel)
Since we no longer need to actually copy any information from the
previous checkpoint, we can simply remove the call entirely to load
it.
As a follow up, we need to audit places inside the filebased backend
that assume `os.*` functions are going to do what we want them to do,
since in general they will not.
Fixes#2714
Attempting to `pulumi stack rename` a stack which had been created but
never updated, when using the local backend, was broken because
code-paths were not hardened against the snapshot being `nil` (which
is the case for a stack before the initial deployment had been done).
Fixes#2654
If we don't process and report the stderr of `npm install`, the output
is "orphaned" during error condition, and only something like "exit code
1" is reported.
This package's flags conflict with those in google/glog. Replace all
references to this package with references to
pulumi/pulumi/pkg/util/logging, and change that package to explicitly
call `flag.CommandLine.Parse` with an empty slice.
This should make it much easier to consume these packages in downstream
repos that have direct or indirect dependencies on google/glog.
These changes add support for passing `ignoreChanges` paths to resource
providers. This is intended to accommodate providers that perform diffs
between resource inputs and resource state (e.g. all Terraform-based
providers, the k8s provider when using API server dry-runs). These paths
are specified using the same syntax as the paths used in detailed diffs.
In addition to passing these paths to providers, the existing support
for `ignoreChanges` in inputs has been extended to accept paths rather
than top-level keys. It is an error to specify a path that is missing
one or more component in the old or new inputs.
Fixes#2936, #2663.
This removes the need for a replace directive in every downstream `go.mod`,
however it does not protect against the case of a `go.mod` being added upstream
with a different import path in future. This seems unlikely given the cadence of
work upstream, however.

The current CLI update view attributes all policy violation errors to
the root Stack resource. This commit will attribute them to the resource
that violated the policy.
The reason for this mis-attribution is a simple bookkeeping error:
* Resource policies intercept and prevent RegisterResource requests for
when the resource in question violates some policy.
* The CLI "tree" view of resources "hides" rows for resources that have
not been registered. Thus, if a policy violation occurs for a
resource, it becomes "orphaned" and is attributed to the stack,
because there is no row for the resource that violates the policy.
The solution, thus, is to simply set the "hidden" flag to false when we
encounter a policy violation.
Fixespulumi/pulumi-policy#25
This commit will allow the Pulumi service HTTP client to deserialize
HTTP responses that have bodies encoded as `application/octet-stream` to
be deserialized as `[]byte`.
This fixes a small bug that causes the HTTP client to fail under these
circumstances, as it expects any body to be JSON-deserializable.
This commit will implement the core business logic of `pulumi policy
publish` -- code to boot an analyzer, ask it for metadata about the
policies it contains, pack the code, and transmit all of this to the
Pulumi service.

A resource can be imported by setting the `import` property in the
resource options bag when instantiating a resource. In order to
successfully import a resource, its desired configuration (i.e. its
inputs) must not differ from its actual configuration (i.e. its state)
as calculated by the resource's provider.
There are a few interesting state transitions hiding here when importing
a resource:
1. No prior resource exists in the checkpoint file. In this case, the
resource is simply imported.
2. An external resource exists in the checkpoint file. In this case, the
resource is imported and the old external state is discarded.
3. A non-external resource exists in the checkpoint file and its ID is
different from the ID to import. In this case, the new resource is
imported and the old resource is deleted.
4. A non-external resource exists in the checkpoint file, but the ID is
the same as the ID to import. In this case, the import ID is ignored
and the resource is treated as it would be in all cases except for
changes that would replace the resource. In that case, the step
generator issues an error that indicates that the import ID should be
removed: were we to move forward with the replace, the new state of
the stack would fall under case (3), which is almost certainly not
what the user intends.
Fixes#1662.
Instead of simply converting a detailed diff entry that indicates an
update to an entire composite value as a simple old/new value diff,
compute the nested diff. This alllows us to render a per-element diff
for the nested object rather than simply displaying the new and the old
composite values.
This is necessary in order to improve diff rendering once
pulumi/pulumi-terraform#403 has been rolled out.
Thse changes make a subtle but critical adjustment to the process the
Pulumi engine uses to determine whether or not a difference exists
between a resource's actual and desired states, and adjusts the way this
difference is calculated and displayed accordingly.
Today, the Pulumi engine get the first chance to decide whether or not
there is a difference between a resource's actual and desired states. It
does this by comparing the current set of inputs for a resource (i.e.
the inputs from the running Pulumi program) with the last set of inputs
used to update the resource. If there is no difference between the old
and new inputs, the engine decides that no change is necessary without
consulting the resource's provider. Only if there are changes does the
engine consult the resource's provider for more information about the
difference. This can be problematic for a number of reasons:
- Not all providers do input-input comparison; some do input-state
comparison
- Not all providers are able to update the last deployed set of inputs
when performing a refresh
- Some providers--either intentionally or due to bugs--may see changes
in resources whose inputs have not changed
All of these situations are confusing at the very least, and the first
is problematic with respect to correctness. Furthermore, the display
code only renders diffs it observes rather than rendering the diffs
observed by the provider, which can obscure the actual changes detected
at runtime.
These changes address both of these issues:
- Rather than comparing the current inputs against the last inputs
before calling a resource provider's Diff function, the engine calls
the Diff function in all cases.
- Providers may now return a list of properties that differ between the
requested and actual state and the way in which they differ. This
information will then be used by the CLI to render the diff
appropriately. A provider may also indicate that a particular diff is
between old and new inputs rather than old state and new inputs.
Fixes#2453.
Currently if you log into s3://bucket/subdirectory, Pulumi will write
files to s3://bucket/.pulumi and not s3://bucket/subdirectory/.pulumi,
this corrects the error.
Recent changes to default provider semantics and the addition of
resource aliases allow a resource's provider reference to change even if
the resource itself is considered to have no diffs. `mustWrite` did not
expect this scenario, and indeed asserted against it. These changes
update `mustWrite` to detect such changes and require that the
checkpoint be written if and when they occur.
Fixes#2804.
Previously, when the CLI wanted to install a plugin, it used a special
method, `DownloadPlugin` on the `httpstate` backend to actually fetch
the tarball that had the plugin. The reason for this is largely tied
to history, at one point during a closed beta, we required presenting
an API key to download plugins (as a way to enforce folks outside the
beta could not download them) and because of that it was natural to
bake that functionality into the part of the code that interfaced with
the rest of the API from the Pulumi Service.
The downside here is that it means we need to host all the plugins on
`api.pulumi.com` which prevents community folks from being able to
easily write resource providers, since they have to manually manage
the process of downloading a provider to a machine and getting it on
the `$PATH` or putting it in the plugin cache.
To make this easier, we add a `--server` argument you can pass to
`pulumi plugin install` to control the URL that it attempts to fetch
the tarball from. We still have perscriptive guidence on how the
tarball must be
named (`pulumi-[<type>]-[<provider-name>]-vX.Y.Z.tar.gz`) but the base
URL can now be configured.
Folks publishing packages can use install scripts to run `pulumi
plugin install` passing a custom `--server` argument, if needed.
There are two improvements we can make to provide a nicer end to end
story here:
- We can augment the GetRequiredPlugins method on the language
provider to also return information about an optional server to use
when downloading the provider.
- We can pass information about a server to download plugins from as
part of a resource registration or creation of a first class
provider.
These help out in cases where for one reason or another where `pulumi
plugin install` doesn't get run before an update takes place and would
allow us to either do the right thing ahead of time or provide better
error messages with the correct `--server` argument. But, for now,
this unblocks a majority of the cases we care about and provides a
path forward for folks that want to develop and host their own
resource providers.
Adds a new resource option `aliases` which can be used to rename a resource. When making a breaking change to the name or type of a resource or component, the old name can be added to the list of `aliases` for a resource to ensure that existing resources will be migrated to the new name instead of being deleted and replaced with the new named resource.
There are two key places this change is implemented.
The first is the step generator in the engine. When computing whether there is an old version of a registered resource, we now take into account the aliases specified on the registered resource. That is, we first look up the resource by its new URN in the old state, and then by any aliases provided (in order). This can allow the resource to be matched as a (potential) update to an existing resource with a different URN.
The second is the core `Resource` constructor in the JavaScript (and soon Python) SDKs. This change ensures that when a parent resource is aliased, that all children implicitly inherit corresponding aliases. It is similar to how many other resource options are "inherited" implicitly from the parent.
Four specific scenarios are explicitly tested as part of this PR:
1. Renaming a resource
2. Adopting a resource into a component (as the owner of both component and consumption codebases)
3. Renaming a component instance (as the owner of the consumption codebase without changes to the component)
4. Changing the type of a component (as the owner of the component codebase without changes to the consumption codebase)
4. Combining (1) and (3) to make both changes to a resource at the same time
If --suppress-outputs is passed to `pulumi preview --json`, we
should not emit the stack outputs. This change fixespulumi/pulumi#2765.
Also adds a test case for this plus some variants of updates.
We were not actually calling our colorization routines, which lead to
printing this very confusing text:
```
<{%reset%}> --outputs:--<{%reset%}>
```
When running updates with `--diff` or when drilling into details of a
proposed operation, like a refresh.
We were dropping new and old states on the floor instead of including
them as part of the previewed operation due to a logic error (we want
to append them when there are no errors from serialization, vs when
there are errors).
When creating a new stack using the local backend, the default
checkpoint has no deployment. That means there's a nil snapshot
created, which means our strategy of using the base snapshot's secrets
manager was not going to work. Trying to do so would result in a panic
because the baseSnapshot is nil in this case.
Using the secrets manager we are going to use to persist the snapshot
is a better idea anyhow, as that's what's actually going to be burned
into the deployment when we serialize the snapshot, so let's use that
instead.
