@keen99 pointed out that newer versions of golangci-lint were failing
due to some spelling errors. This change fixes them up. We have also
now have a work item to track moving to a newer golangci-lint tool in
the future.
Fixes#2841
We no longer support Node 6.X (it went end of life at the end of
April, we stopped testing on it, and now we use features that are not
in Node 6 like `Object.values`.
Note that we support 8+, and add an `engines` section to our
package.json so folks who try to install on older versions of node see
warnings.
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.
This commit will expose the new `Invoke` routine that lists resource
outputs through the Node.js SDK.
This API is implemented via a new API, `EnumerablePromise`, which is a
collection of simple query primitives built onto the `Promise` API. The
query model is lazy and LINQ-like, and generally intended to make
`Promise` simpler to deal with in query scenarios. See #2601 for more
details.
Fixes#2600.
Running `pulumi query` over state resources will require the ability to
filter resources by type.
This commit begins the process of making this possible simply, using the
TypeScript user-defined type guards feature. This commit changes the
`CustomResource` constructor to record the `t` argument in the
`__pulumiType` field, which acts as a "sentinel" value in the resource
base, which deriving classes need only check to ensure they are of that
type. For example:
aws.s3.Bucket.isInstance(someOb)
would check the `aws.s3.Bucket.__pulumiType` field, and make sure that
the type field lines up.
This commit touches an intersection of a few different provider-oriented
features that combined to cause a particularly severe bug that made it
impossible for users to upgrade provider versions without seeing
replacements with their resources.
For some context, Pulumi models all providers as resources and places
them in the snapshot like any other resource. Every resource has a
reference to the provider that created it. If a Pulumi program does not
specify a particular provider to use when performing a resource
operation, the Pulumi engine injects one automatically; these are called
"default providers" and are the most common ways that users end up with
providers in their snapshot. Default providers can be identified by
their name, which is always prefixed with "default".
Recently, in an effort to make the Pulumi engine more flexible with
provider versions, it was made possible for the engine to have multiple
default providers active for a provider of a particular type, which was
previously not possible. Because a provider is identified as a tuple of
package name and version, it was difficult to find a name for these
duplicate default providers that did not cause additional problems. The
provider versioning PR gave these default providers a name that was
derived from the version of the package. This proved to be a problem,
because when users upgraded from one version of a package to another,
this changed the name of their default provider which in turn caused all
of their resources created using that provider (read: everything) to be
replaced.
To combat this, this PR introduces a rule that the engine will apply
when diffing a resource to determine whether or not it needs to be
replaced: "If a resource's provider changes, and both old and new
providers are default providers whose properties do not require
replacement, proceed as if there were no diff." This allows the engine
to gracefully recognize and recover when a resource's default provider changes
names, as long as the provider's config has not changed.
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
