* Relax baseline for the TestEngineEventPerf test
The mesurments we used to compute the baseline were on a local recent
MacBook. We added some slack, but we've already seen instances of the
baseline being too tight, even with no changes in product code.
This is most common on the OSX machines in Travis, which in general
seem quite slow for many workloads.
We'll bump it up to 8 seconds and if we start hitting that as well,
we'll need to do something more serious.
'python' is not usually symlinked to 'python3' on most distros unless
you are already running in a virtual environment. Launching 'python3'
explicitly ensures that we will either launch the program successfully
or immediately fail, instead of launching the program with Python 2 and
failing with syntax errors at runtime.
This commit also emits an error message asking users to install Python
3.6 or later if we failed to find the 'python3' executable.
Because of a bug in our version scripts (which will be addressed by
pulumi/pulumi#2216) we generate a goofy version when building an
untagged commit in the release branches. That causes our logic to
decide if it should print the upgrade message or not to print an
upgrade message, because it thinks the CLI is out of date.
It then prints the upgrade message and a test fails because it is
expecting an empty stderr.
Just stop checking that stderr was empty, and just validate standard
out.
These changes add a new resource to the Pulumi SDK,
`pulumi.StackReference`, that represents a reference to another stack.
This resource has an output property, `outputs`, that contains the
complete set of outputs for the referenced stack. The Pulumi account
performing the deployment that creates a `StackReference` must have
access to the referenced stack or the call will fail.
This resource is implemented by a builtin provider managed by the engine.
This provider will be used for any custom resources and invokes inside
the `pulumi:pulumi` module. Currently this provider supports only the
`pulumi:pulumi:StackReference` resource.
Fixes#109.
We run the same suite of changes that we did on gometalinter. This
ended up catching a few new issues, some of which were addressed and
some of which were baselined.
* Implement RegisterResourceOutputs for Python 3
RegisterResourceOutputs allows Python 3 programs to export stack outputs
and export outputs off of component resources (which, under the hood,
are the same thing).
Adds a new integration test for stack outputs for Python programs, as
well as add a langhost test for register resource outputs.
Fixespulumi/pulumi#2163
* CR: Rename stack_output -> export
Fix integration tests that hardcoded paths to stack_outputs
* Fix one more reference to stack_outputs
* Fix Python support in integration test framework
Update the integratino test framework to use pipenv to bootstrap new
virtual environments for tests and use those virtual environments to run
pulumi update and pulumi preview.
Fixespulumi/pulumi#2138
* Install packages via 'Dependencies' field
* Remove code for installing packages from Dependencies
In preparation for some workspace restructuring, I decided to scratch a
few itches of my own in the code:
* Change project's RuntimeInfo field to just Runtime, to match the
serialized name in JSON/YAML.
* Eliminate the no-longer-used Context and NoDefaultIgnores fields on
project, and all of the associated legacy PPC-related code.
* Eliminate the no-longer-used IgnoreFile constant.
* Remove a bunch of "// nolint: lll" annotations, and simply format
the structures with comments on dedicated lines, to avoid overly
lengthy lines and lint suppressions.
* Mark Dependencies and InitErrors as `omitempty` in the JSON
serialization directives for CheckpointV2 files. This was done for
the YAML directives, but (presumably accidentally) omitted for JSON.
* Implement RPC for Python 3
* Try not setting PYTHONPATH
* Remove PYTHONPATH line
* Implement Invoke for Python 3
* Implement register resource
* progress
* Rewrite the whole thing
* Fix a few bugs
* All tests pass
* Fix an abnormal shutdown bug
* CR feedback
* Provide a hook for resources to rename properties
As dictionaries and other classes come from the engine, the
translate_property hook can be used to intercept them and rename
properties if desired.
* Fix variable names and comments
* Disable Python integration tests for now
If you took the time to type out `--skip-preview`, we should have high
confidence that you don't want a preview and you're okay with the
operation just happening without a prompt.
Fixes#1448
This adds an option, --suppress-outputs, to many commands, to
avoid printing stack outputs for stacks that might contain sensitive
information in their outputs (like key material, and whatnot).
Fixespulumi/pulumi#2028.
This change adds a --json (short -j) flag for `pulumi stack output`
that prints the results as JSON, rather than our ad-hoc format.
Fixespulumi/pulumi#1863.
This is consistent with the behavior prior to the introduction of Read
steps. In order to avoid a breaking change we must do this check in the
engine itself, which causes a bit of a layering violation: because IDs
are marshaled as raw strings rather than PropertyValues, the engine must
check against the marshaled form of an unknown directly (i.e.
`plugin.UnknownStringValue`).
### First-Class Providers
These changes implement support for first-class providers. First-class
providers are provider plugins that are exposed as resources via the
Pulumi programming model so that they may be explicitly and multiply
instantiated. Each instance of a provider resource may be configured
differently, and configuration parameters may be source from the
outputs of other resources.
### Provider Plugin Changes
In order to accommodate the need to verify and diff provider
configuration and configure providers without complete configuration
information, these changes adjust the high-level provider plugin
interface. Two new methods for validating a provider's configuration
and diffing changes to the same have been added (`CheckConfig` and
`DiffConfig`, respectively), and the type of the configuration bag
accepted by `Configure` has been changed to a `PropertyMap`.
These changes have not yet been reflected in the provider plugin gRPC
interface. We will do this in a set of follow-up changes. Until then,
these methods are implemented by adapters:
- `CheckConfig` validates that all configuration parameters are string
or unknown properties. This is necessary because existing plugins
only accept string-typed configuration values.
- `DiffConfig` either returns "never replace" if all configuration
values are known or "must replace" if any configuration value is
unknown. The justification for this behavior is given
[here](https://github.com/pulumi/pulumi/pull/1695/files#diff-a6cd5c7f337665f5bb22e92ca5f07537R106)
- `Configure` converts the config bag to a legacy config map and
configures the provider plugin if all config values are known. If any
config value is unknown, the underlying plugin is not configured and
the provider may only perform `Check`, `Read`, and `Invoke`, all of
which return empty results. We justify this behavior becuase it is
only possible during a preview and provides the best experience we
can manage with the existing gRPC interface.
### Resource Model Changes
Providers are now exposed as resources that participate in a stack's
dependency graph. Like other resources, they are explicitly created,
may have multiple instances, and may have dependencies on other
resources. Providers are referred to using provider references, which
are a combination of the provider's URN and its ID. This design
addresses the need during a preview to refer to providers that have not
yet been physically created and therefore have no ID.
All custom resources that are not themselves providers must specify a
single provider via a provider reference. The named provider will be
used to manage that resource's CRUD operations. If a resource's
provider reference changes, the resource must be replaced. Though its
URN is not present in the resource's dependency list, the provider
should be treated as a dependency of the resource when topologically
sorting the dependency graph.
Finally, `Invoke` operations must now specify a provider to use for the
invocation via a provider reference.
### Engine Changes
First-class providers support requires a few changes to the engine:
- The engine must have some way to map from provider references to
provider plugins. It must be possible to add providers from a stack's
checkpoint to this map and to register new/updated providers during
the execution of a plan in response to CRUD operations on provider
resources.
- In order to support updating existing stacks using existing Pulumi
programs that may not explicitly instantiate providers, the engine
must be able to manage the "default" providers for each package
referenced by a checkpoint or Pulumi program. The configuration for
a "default" provider is taken from the stack's configuration data.
The former need is addressed by adding a provider registry type that is
responsible for managing all of the plugins required by a plan. In
addition to loading plugins froma checkpoint and providing the ability
to map from a provider reference to a provider plugin, this type serves
as the provider plugin for providers themselves (i.e. it is the
"provider provider").
The latter need is solved via two relatively self-contained changes to
plan setup and the eval source.
During plan setup, the old checkpoint is scanned for custom resources
that do not have a provider reference in order to compute the set of
packages that require a default provider. Once this set has been
computed, the required default provider definitions are conjured and
prepended to the checkpoint's resource list. Each resource that
requires a default provider is then updated to refer to the default
provider for its package.
While an eval source is running, each custom resource registration,
resource read, and invoke that does not name a provider is trapped
before being returned by the source iterator. If no default provider
for the appropriate package has been registered, the eval source
synthesizes an appropriate registration, waits for it to complete, and
records the registered provider's reference. This reference is injected
into the original request, which is then processed as usual. If a
default provider was already registered, the recorded reference is
used and no new registration occurs.
### SDK Changes
These changes only expose first-class providers from the Node.JS SDK.
- A new abstract class, `ProviderResource`, can be subclassed and used
to instantiate first-class providers.
- A new field in `ResourceOptions`, `provider`, can be used to supply
a particular provider instance to manage a `CustomResource`'s CRUD
operations.
- A new type, `InvokeOptions`, can be used to specify options that
control the behavior of a call to `pulumi.runtime.invoke`. This type
includes a `provider` field that is analogous to
`ResourceOptions.provider`.
This change lets us set runtime specific options in Pulumi.yaml, which
will flow as arguments to the language hosts. We then teach the nodejs
host that when the `typescript` is set to `true` that it should load
ts-node before calling into user code. This allows using typescript
natively without an explicit compile step outside of Pulumi.
This works even when a tsconfig.json file is not present in the
application and should provide a nicer inner loop for folks writing
typescript (I'm pretty sure everyone has run into the "but I fixed
that bug! Why isn't it getting picked up? Oh, I forgot to run tsc"
problem.
Fixes#958
This changes the CLI interface in a few ways:
* `pulumi preview` is back! The alternative of saying
`pulumi update --preview` just felt awkward, and it's a common
operation to want to perform. Let's just make it work.
* There are two flags consistent across all update commands,
`update`, `refresh`, and `destroy`:
- `--skip-preview` will skip the preview step. Note that this
does *not* skip the prompt to confirm that you'd like to proceed.
Indeed, it will still prompt, with a little warning text about
the fact that the preview has been skipped.
* `--yes` will auto-approve the updates.
This lands us in a simpler and more intuitive spot for common scenarios.
I found the flag --force to be a strange name for skipping a preview,
since that name is usually reserved for operations that might be harmful
and yet you're coercing a tool to do it anyway, knowing there's a chance
you're going to shoot yourself in the foot.
I also found that what I almost always want in the situation where
--force was being used is to actually just run a preview and have the
confirmation auto-accepted. Going straight to --force isn't the right
thing in a CI scenario, where you actually want to run a preview first,
just to ensure there aren't any issues, before doing the update.
In a sense, there are four options here:
1. Run a preview, ask for confirmation, then do an update (the default).
2. Run a preview, auto-accept, and then do an update (the CI scenario).
3. Just run a preview with neither a confirmation nor an update (dry run).
4. Just do an update, without performing a preview beforehand (rare).
This change enables all four workflows in our CLI.
Rather than have an explosion of flags, we have a single flag,
--preview, which can specify the mode that we're operating in. The
following are the values which correlate to the above four modes:
1. "": default (no --preview specified)
2. "auto": auto-accept preview confirmation
3. "only": only run a preview, don't confirm or update
4. "skip": skip the preview altogether
As part of this change, I redid a bit of how the preview modes
were specified. Rather than booleans, which had some illegal
combinations, this change introduces a new enum type. Furthermore,
because the engine is wholly ignorant of these flags -- and only the
backend understands them -- it was confusing to me that
engine.UpdateOptions stored this flag, especially given that all
interesting engine options _also_ accepted a dryRun boolean. As of
this change, the backend.PreviewBehavior controls the preview options.
This change removes the need to `pulumi init` when targeting the local
backend. A fair amount of the change lays the foundation that the next
set of changes to stop having `pulumi init` be used for cloud stacks
as well.
Previously, `pulumi init` logically did two things:
1. It created the bookkeeping directory for local stacks, this was
stored in `<repository-root>/.pulumi`, where `<repository-root>` was
the path to what we belived the "root" of your project was. In the
case of git repositories, this was the directory that contained your
`.git` folder.
2. It recorded repository information in
`<repository-root>/.pulumi/repository.json`. This was used by the
cloud backend when computing what project to interact with on
Pulumi.com
The new identity model will remove the need for (2), since we only
need an owner and stack name to fully qualify a stack on
pulumi.com, so it's easy enough to stop creating a folder just for
that.
However, for the local backend, we need to continue to retain some
information about stacks (e.g. checkpoints, history, etc). In
addition, we need to store our workspace settings (which today just
contains the selected stack) somehere.
For state stored by the local backend, we change the URL scheme from
`local://` to `local://<optional-root-path>`. When
`<optional-root-path>` is unset, it defaults to `$HOME`. We create our
`.pulumi` folder in that directory. This is important because stack
names now must be unique within the backend, but we have some tests
using local stacks which use fixed stack names, so each integration
test really wants its own "view" of the world.
For the workspace settings, we introduce a new `workspaces` directory
in `~/.pulumi`. In this folder we write the workspace settings file
for each project. The file name is the name of the project, combined
with the SHA1 of the path of the project file on disk, to ensure that
multiple pulumi programs with the same project name have different
workspace settings.
This does mean that moving a project's location on disk will cause the
CLI to "forget" what the selected stack was, which is unfortunate, but
not the end of the world. If this ends up being a big pain point, we
can certianly try to play games in the future (for example, if we saw
a .git folder in a parent folder, we could store data in there).
With respect to compatibility, we don't attempt to migrate older files
to their newer locations. For long lived stacks managed using the
local backend, we can provide information on where to move things
to. For all stacks (regardless of backend) we'll require the user to
`pulumi stack select` their stack again, but that seems like the
correct trade-off vs writing complicated upgrade code.
Our normal lifecycle tests always call pulumi stack rm, but some of
the tests that used the more barebones framework did not do so. This
was "ok" in the past, since all bookkeeping data about a stack was
stored next to the Pulumi program itself and we deleted that folder
once the test passed.
As part of removing `pulumi init` workspace tracking will move to
~/.pulumi/workspaces and so we'd like to have a gesture that actually
removes the stack, which will cause the workspace file to be removed
as well, instead of littering ~/.pulumi/workspaces with tests.
Upcoming work to remove the need for `pulumi init` makes testing the
upgrade code much harder than it did in the past (since workspace data
is moving to a different location on the file system, as well as some
other changes).
Instead of trying to maintain the code and test, let's just remove
it. Folks who haven't migrated (LM and the PPC deployment in the
service) should use the 0.11.3 or earlier CLI to migrate their
projects (simply by logging in and running a pulumi command) or move
things forward by hand.
This change does three major things:
1. Removes the ability to be logged into multiple clouds at the same
time. Previously, we supported being logged into multiple clouds at
the same time and the CLI would fan out requests and join responses
when needed. In general, this was only useful for Pulumi employees
that wanted run against multiple copies of the service (say production
and staging) but overall was very confusing (for example in the old
world a stack with the same identity could appear twice (since it was
in two backends) which the CLI didn't handle very well).
2. Stops treating the "local" backend as a special thing, from the
point of view of the CLI. Previouly we'd always connect to the local
backend and merge that data with whatever was in clouds we were
connected to. We had gestures like `--local` in `pulumi stack init`
that meant "use the local mode". Instead, to use the local mode now
you run `pulumi login --cloud-url local://` and then you are logged in
the local backend. Since you can only ever be logged into a single
backend, we can remove the `--local` and `--remote` flags from `pulumi
stack init`, it just now requires you to be logged in and creates a
stack in whatever back end you were logged into. When logging into the
local backend, you are not prompted for an access key.
3. Prompt for login in places where you have to log in, if you are not
already logged in.
Tests now target managed stacks instead of local stacks.
The existing logged in user and target backend API are used unless PULUMI_ACCES_TOKEN is defined, in which case tests are run under that access token and against the PULUMI_API backend.
For developer machines, we will now need to be logged in to Pulumi to run tests, and whichever default API backend is logged in (the one listed as current in ~/.pulumi/credentials.json) will be used. If you need to override these, provide PULUMI_ACCESS_TOKEN and possibly PULUMI_API.
For Travis, we currently target the staging service using the Pulumi Bot user.
We have decided to run tests in the pulumi organization. This can be overridden for local testing (or in Travis in the future) by defining PULUMI_API_OWNER_ORGANIZATION and using an access token with access to that organization.
Part of pulumi/home#195.
config.Key has become a pair of namespace and name. Because the whole
world has not changed yet, there continues to be a way to convert
between a tokens.ModuleMember and config.Key, however now sometime the
conversion from tokens.ModuleMember can fail (when the module member
is not of the form `<package>:config:<name>`).
Right now, config.Key is a type alias for tokens.ModuleMember. I did a
pass over the codebase such that we use config.Key everywhere it
looked like the value did not leak to some external process (e.g a
resource provider or a langhost).
Doing this makes it a little clearer (hopefully) where code is
depending on a module member structure (e.g. <package>:config:<value>)
instead of just an opaque type.
Migrate configuration from the old model to the new model. The
strategy here is that when we first run `pulumi` we enumerate all of
the stacks from all of the backends we know about and for each stack
get the configuration values from the project and workspace and
promote them into the new file. As we do this, we remove stack
specific config from the workspace and Pulumi.yaml file.
If we are able to upgrade all the stacks we know about, we delete all
global configuration data in the workspace and in Pulumi.yaml as well.
We have a test that ensures upgrades continue to work.
This change updates our configuration model to make it simpler to
understand by removing some features and changing how things are
persisted in files.
Notable changes:
- We've removed the notion of "workspace" vs "project"
config. Now, configuration is always stored in a file next to
`Pulumi.yaml` named `Pulumi.<stack-name>.yaml` (the same file we'd
use for an other stack specific information we would need to persist
in the future).
- We've removed the notion of project wide configuration. Every new
stack gets a completely empty set of configuration and there's no
way to share common values across stacks, instead the common value
has to be set on each stack.
We retain some of the old code for the configuration system so we can
support upgrading a project in place. That will happen with the next
change.
This change fixes some issues and allows us to close some
others (since they are no longer possible).
Fixes#866Closes#872Closes#731
We are going to be changing the configuration model. To begin, let's
take most of the existing stuff and mark it as "deprecated" so we can
keep the existing behavior (to help transition newer code forward)
while making it clear what APIs should not be called in the
implementation of `pulumi` itself.
