We use `git describe --tags` to construct a version number based on
the current version tag.
The properties VERSION (when using make) and Version (when using
MSBuild) can be explicitly set to use a fixed value instead.
Fixes#13
Previously, you had to fully qualify configuration values (e.g
example:config:message). As a convience, let's support adding
configuration values where the key is not a fully qualified module
member. In this case, we'll treat the key as if
`<program-name>:config:` had been prepended to it.
In addition, when we print config, shorten keys of the form
`<program-name>:config:<key-name>` to `<key-name>`.
I've updated one integration test to use the new syntax and left the
other as is to ensure both continue to work.
Previously we used the word "Environment" as the term for a deployment
target, but since then we've started to use the term Stack. Adopt this
across the CLI.
From a user's point of view, there are a few changes:
1. The `env` verb has been renamed to `stack`
2. The `-e` and `--env` options to commands which operate on an
environment now take `-s` or `--stack` instead.
3. Becase of (2), the commands that used `-s` to display a summary now
only support passing the full option name (`--summary`).
On the local file system, we still store checkpoint data in the `env`
sub-folder under `.pulumi` (so we can reuse existing checkpoint files
that were written to the old folder)
Our checkpoint file is now in a shape such that go's built in
marshalling and unmarshalling is sufficent, so we can remove the code
we had on our decode path to do extra validation
Previously, the engine would write to io.Writer's to display output.
When hosted in `pulumi` these writers were tied to os.Stdout and
os.Stderr, but other applications hosting the engine could send them
other places (e.g. a log to be sent to an another application later).
While much better than just using the ambient streams, this was still
not the best. It would be ideal if the engine could just emit strongly
typed events and whatever is hosting the engine could care about
displaying them.
As a first step down that road, we move to a model where operations on
the engine now take a `chan engine.Event` and during the course of the
operation, events are written to this channel. It is the
responsibility of the caller of the method to read from the channel
until it is closed (singifying that the operation is complete).
The events we do emit are still intermingle presentation with data,
which is unfortunate, but can be improved over time. Most of the
events today are just colorized in the client and printed to stdout or
stderr without much thought.
The checkpoint is an implementation detail of the storage of an
environment. Instead of interacting with it, make sure that all the
data we need from it either hangs off the Snapshot or Target
objects (which you can get from a Checkpoint) and then start consuming
that data.
Internally we end up using flag to parse our command lines because of
our dependency on glog. When flag does not know about -C, if someone
passes -C before the sub command name (as is common for folks coming
from Git) the flag package terminates the program because -C was not
defined. So just teach flag this exists until we takle #301 and rid
ourselves of glog.
Previously, you could pass an explicit path to a Pulumi program when
running preview or update and the tool would use that program when
planning or deploying, but continue to write state in the cwd. While
being able to operate on a specific package without having to cd'd all
over over the place is nice, this specific implemntation was a little
scary because it made it easier to run two different programs with the
same local state (e.g config and checkpoints) which would lead to
surprising results.
Let's move to a model that some tools have where you can pass a
working directory and the tool chdir's to that directory before
running. This way any local state that is stored will be stored
relative to the package we are operating on instead of whatever the
current working directory is.
Fixes#398
Previously, the engine was concered with maintaing information about
the currently active environment. Now, the CLI is in charge of
this. As part of this change, the engine can now assume that every
environment has a non empty name (and I've added asserts on the
entrypoints of the engine API to ensure that any consumer of the
engine passes a non empty environment name)
The CLI is now responsible for actually displaying information and the
engine is only concerned with getting the configuration. As part of
this change, I've removed the display a single configuration value API
from the engine. It can now be done in terms of getting all the config
for an environment and selecting the value the user is interested in
Previously the engine was concerned with displaying information about
the environment. Now the engine returns an environment info object
which the CLI uses to display environment information.
This includes a few changes:
* The repo name -- and hence the Go modules -- changes from pulumi-fabric to pulumi.
* The Node.js SDK package changes from @pulumi/pulumi-fabric to just pulumi.
* The CLI is renamed from lumi to pulumi.
This change flips the polarity on parallelism: rather than having a
--serialize flag, we will have a --parallel=P flag, and by default
we will shut off parallelism. We aren't benefiting from it at the
moment (until we implement pulumi/pulumi-fabric#106), and there are
more hidden dependencies in places like AWS Lambdas and Permissions
than I had realized. We may revisit the default, but this allows
us to bite off the messiness of dependsOn only when we benefit from
it. And in any case, the --parallel=P capability will be useful.
This change adds an optiona dependsOn parameter to Resource constructors,
to "force" a fake dependency between resources. We have an extremely strong
desire to resort to using this only in unusual cases -- and instead rely
on the natural dependency DAG based on properties -- but experience in other
resource provisioning frameworks tells us that we're likely to need this in
the general case. Indeed, we've already encountered the need in AWS's
API Gateway resources... and I suspect we'll run into more especially as we
tackle non-serverless resources like EC2 Instances, where "ambient"
dependencies are far more commonplace.
This also makes parallelism the default mode of operation, and we have a
new --serialize flag that can be used to suppress this default behavior.
Full disclosure: I expect this to become more Make-like, i.e. -j 8, where
you can specify the precise width of parallelism, when we tackle
pulumi/pulumi-fabric#106. I also think there's a good chance we will flip
the default, so that serial execution is the default, so that developers
who don't benefit from the parallelism don't need to worry about dependsOn
in awkward ways. This tends to be the way most tools (like Make) operate.
This fixespulumi/pulumi-fabric#335.
As explained in pulumi/pulumi-fabric#293, we were a little ad-hoc in
how configuration was "applied" to resource providers.
In fact, config wasn't ever communicated directly to providers; instead,
the resource providers would simply ask the engine to read random heap
locations (via tokens). Now that we're on a plan where configuration gets
handed to the program at startup, and that's that, and where generally
speaking resource providers never communicate directly with the language
runtime, we need to take a different approach.
As such, the resource provider interface now offers a Configure RPC
method that the resource planning engine will invoke at the right
times with the right subset of configuration variables filtered to
just that provider's package. This fixespulumi/pulumi#293.
The existing implementation of the interface (backed by the file
system) has moved into cmd/lumi. The deployment service will start to
provide its own version.
`saveEnv` had a flag which would prevent an environment from being
overwritten if it already existed, which was only used by `lumi env
init`. Refactor the code so the check is done inside `lumi` instead of
against this API. We don't need this functionality for the service and
so requiring support for this at the API boundary for environments
feels like a bad idea.
We'd like to abstract out environment CRUD operations and I'd prefer
not to have to bake in the conspect of a file name like thing in the
abstraction. Since we were not really using this feature many places,
let's just get rid of it.
This refactors the engine so all of the APIs on it are instance
methods on the type instead of raw methods that float around and use
data from a global engine.
A mechcanical change as we remove the global `E` and then make
anything that interacted with that in pkg/engine to be an instance
method and the dealing with the fallout.
Prevously, we would throw raw args arrays across the interface and the
engine would do some additional parsing. Clean this up so we don't do
that and all the parsing stays in `lumi`
