1. Various idiomatic Go and TypeScript fixes
2. Add an integration test that end-to-end roundtrips dependency
information for a simple Pulumi program
3. Add an additional test assert that tests that dependency information
comes from the language host as expected
This commit does two things:
1. All dependencies of a resource, both implicit and explicit, are
communicated directly to the engine when registering a resource. The
engine keeps track of these dependencies and ultimately serializes
them out to the checkpoint file upon successful deployment.
2. Once a successful deployment is done, the new `pulumi stack
graph` command reads the checkpoint file and outputs the dependency
information within in the DOT format.
Keeping track of dependency information within the checkpoint file is
desirable for a number of reasons, most notably delete-before-create,
where we want to delete resources before we have created their
replacement when performing an update.
I was reminded of this yesterday with unprintable characters as I
debugged some things on Windows. Inspired by Yarn, this change adds
a new flag --emoji (-e for short) that can be used to control whether
we show ASCII-only characters or not in the console. On Mac, it
defaults to true, and on Windows and Linux, it defaults to false.
This also brings back the retro ASCII-friendly progress spinner
when --emoji is disabled.
Backup copies of local stack checkpoints are now saved to the
user's home directory (`~/.pulumi/backups`) by default.
This enables users to recover after accidentally deleting their
local `.pulumi` directory (e.g. via `git clean`).
The behavior can be disabled by setting the
PULUMI_DISABLE_CHECKPOINT_BACKUPS environment variable, which
we use to disable backups when running all tests other than the
test for this functionality.
This change refactors the way we do ${VERSION} substitution in both
the Node.js SDK's version.js and package.json, so that it can work on
Windows. This is required now that we are actually parsing semvers.
For some tools we used, like `dep` and `gometalinter` we were just
calling `go install` which caused us to pick up whatever was in `HEAD`
at that time. Now, we move to a model where we install fixed versions,
which will change per milestone.
While doing this, I changed the way our .travis.yml file runs
everything to move as much as possible out into scripts and do so in a
way that allows us to share as much common logic across our
repositories.
On Windows, when we launch the language host, it will end up with
a ".exe" file extension at the end of os.Args[0]. This leads us to
produce a garbage filename for the -exec script -- namely,
pulumi-language-nodejs.exe-exec -- which, of course fails. We simply
need to trim off the ".exe" bit before producing the script name.
We have had a long-standing bug in here where we waiting on a
stdout channel that never got populated, when the language plugin
fails to load entirely. This would lead to hung processes. The
fix is simple: only wait for stdout/stderr channels to drain that
have actually been wired up to enjoy the requisite signaling.
This adds support for two things:
* Installing all plugins that a project requires with a single command:
$ pulumi plugin install
* Listing the plugins that this project requires:
$ pulumi plugin ls --project
$ pulumi plugin ls -p
Prior to this change, we had a flat list of files in the
~/.pulumi/plugins directory. This was simple but unfortunately
too naive, since we in fact have multi-file plugins already.
Dumping them in the same directory increases the risk of a
collision. Instead, let's put them in their own directories.
This means, for example, you'll see things like
~/.pulumi/plugins/
resource-aws-v0.11.0-dev-8-g57a0d62/
README.txt
pulumi-resource-aws
Notice that the binary name stays the same -- e.g., in this
case pulumi-resource-aws -- and does not include the version.
This makes it simple to add it to your $PATH in the usual ways
and have it loaded as a preferred location.
This change renames prune to rm, to match what we use for other
similar commands. Someday perhaps we will add a prune that uses
some smarts to prune old plugins, etc.
Also tidy up some minor things about the command. For example,
we now require --all if you want to truly clear the entire plugin
cache. We also print more detail, like the full list of plugins
to be removed, in the confirmation prompt.
The API/REST logic auto-prepended "/api", which we don't want
for the release downloads. This change just alters callsites
to specify the full path (which I prefer being explicit anyway).
This brings back the Node.js language plugin's GetRequiredPlugins
function, reimplemented in Go now that the language host has been
rewritten from JavaScript. Fairly rote translation, along with
some random fixes required to get tests passing again.
This enables you to install a plugin directly from a file, rather
than the default of downloading it from our release share. This is
primarily useful as a test tool, but will also be a useful escape
hatch for 3rd party extensibility, where we do not have a share.
$ pulumi plugin install resource aws v0.1.0 -f my_aws_provider.tgz
This change implements the Node.js language host's GetRequiredPlugins
function. This merely scans all node_modules/*/package.json files in
the program directory, looking for those that have associated plugins.
It returns a list of any found along with their version numbers.
This change adds a GetRequiredPlugins RPC method to the language
host, enabling us to query it for its list of plugin requirements.
This is language-specific because it requires looking at the set
of dependencies (e.g., package.json files).
It also adds a call up front during any update/preview operation
to compute the set of plugins and require that they are present.
These plugins are populated in the cache and will be used for all
subsequent plugin-related operations during the engine's activity.
We now cache the language plugins, so that we may load them
eagerly too, which we never did previously due to the fact that
we needed to pass the monitor address at load time. This was a
bit bizarre anyhow, since it's really the Run RPC function that
needs this information. So, to enable caching and eager loading
-- which we need in order to invoke GetRequiredPlugins -- the
"phone home" monitor RPC address is passed at Run time.
In a subsequent change, we will switch to faulting in the plugins
that are missing -- rather than erroring -- in addition to
supporting the `pulumi plugin install` CLI command.
This change introduces a workspace.GetPluginPath function that probes
the central workspace cache of plugins for a matching plugin binary that
matches the desired kind, name, and, optionally, version. It also permits
overriding this with $PATH for developer scenarios.
The analyzer, language, and resource plugin logic now uses this function
for deciding which binary path to load at runtime.
This change implements basic plugin management, but we do not yet
actually use the plugins for anything (that comes next).
Plugins are stored in `~/.pulumi/plugins`, and are expected to be
in the format `pulumi-<KIND>-<NAME>-v<VERSION>[.exe]`. The KIND is
one of `analyzer`, `language`, or `resource`, the NAME is a hyphen-
delimited name (e.g., `aws` or `foo-bar`), and VERSION is the
plugin's semantic version (e.g., `0.9.11`, `1.3.7-beta.a736cf`, etc).
This commit includes four new CLI commands:
* `pulumi plugin` is the top-level plugin command. It does nothing
but show the help text for associated child commands.
* `pulumi plugin install` can be used to install plugins manually.
If run with no additional arguments, it will compute the set of
plugins used by the current project, and download them all. It
may be run to explicitly download a single plugin, however, by
invoking it as `pulumi plugin install KIND NAME VERSION`. For
example, `pulumi plugin install resource aws v0.9.11`. By default,
this command uses the cloud backend in the usual way to perform the
download, although a separate URL may be given with --cloud-url,
just like all other commands that interact with our backend service.
* `pulumi plugin ls` lists all plugins currently installed in the
plugin cache. It displays some useful statistics, like the size
of the plugin, when it was installed, when it was last used, and
so on. It sorts the display alphabetically by plugin name, and
for plugins with multiple versions, it shows the newest at the top.
The command also summarizes how much disk space is currently being
consumed by the plugin cache. There are no filtering capabilities yet.
* `pulumi plugin prune` will delete plugins from the cache. By
default, when run with no arguments, it will delete everything.
It may be run with additional arguments, KIND, NAME, and VERSION,
each one getting more specific about what it will delete. For
instance, `pulumi plugin prune resource aws` will delete all AWS
plugin versions, while `pulumi plugin prune resource aws <0.9`
will delete all AWS plugins before version 0.9. Unless --yes is
passed, the command will confirm the deletion with a count of how
many plugins will be affected by the command.
We do not yet actually download plugins on demand yet. That will
come in a subsequent change.
New-Item produces a new object on success, which ultimately gets
output by the make_release.ps1 cmdlet and consumed by the release.ps1
script. This messes up the release script that is expecting exactly
one object to come out of the pipeline from make_release.ps1.
Fixes#356. Instead of downloading a node binary with our closure
serialization code linked-in, this PR instead publishes the
`nativeruntime.node` produced by the NodeJS SDK build as part of the SDK.
This has a number of advantages. First, it is vastly more easy to
develop closure.cc in this configuration. Second, we have the ability
to ship different `nativeruntime.node`s side-by-side, paving the way
for enabling future versions of Node. Third, we don't have to stay
in the business of shipping custom builds of Node, although we do still
need to ship a version of Node with minor modifications in order for
Windows to still work.
This change includes a handful of stack-related CLI formatting
improvements that I've been noodling on in the background for a while,
based on things that tend to trip up demos and the inner loop workflow.
This includes:
* If `pulumi stack select` is run by itself, use an interactive
CLI menu to let the user select an existing stack, or choose to
create a new one. This looks as follows
$ pulumi stack select
Please choose a stack, or choose to create a new one:
abcdef
babblabblabble
> currentlyselected
defcon
<create a new stack>
and is navigated in the usual way (key up, down, enter).
* If a stack name is passed that does not exist, prompt the user
to ask whether s/he wants to create one on-demand. This hooks
interesting moments in time, like `pulumi stack select foo`,
and cuts down on the need to run additional commands.
* If a current stack is required, but none is currently selected,
then pop the same interactive menu shown above to select one.
Depending on the command being run, we may or may not show the
option to create a new stack (e.g., that doesn't make much sense
when you're running `pulumi destroy`, but might when you're
running `pulumi stack`). This again lets you do with a single
command what would have otherwise entailed an error with multiple
commands to recover from it.
* If you run `pulumi stack init` without any additional arguments,
we interactively prompt for the stack name. Before, we would
error and you'd then need to run `pulumi stack init <name>`.
* Colorize some things nicely; for example, now all prompts will
by default become bright white.
Previously, we would just use normal go formatting when displaying
output values. This was fine for simple values like strings and ints,
but for arrays or objects, you'd end up with values that looked a
little stange.
We now run the objects through json.Marshal first, to get nicer string
values for more complex objects. However, when the top level value is
a single string, we elide the quotes. This is not true JSON, but it
displays much nicer.
When we add something like `--format=json` (see pulumi#496) it will
provide a way to treat output unfiormly as JSON.
Fixes#736
Uploading a bunch of tiny files is inefficient. Worse, it results in a ton of
paths printed to `stdout` -- enough that we could hit Travis' 4MB limit and
kill the job before we'd finished uploading.
Now we create a `.tar.gz` and upload that one, compressed file.
We also noticed that copied files might not be accessible from the `dev`
account, even though that account owns the `eng.pulumi.com` bucket. When
files are uploaded by one AWS account to a bucket owned by another, the
objects are, by default, only readable by the first account (the writer).
Change the ACL so the account that owns the bucket also has full access.
The windows build was still on the old plan from way back when where
we had binaries littered in the build tree and you had to add parts of
your build-tree to the `%PATH%` for the integration tests to work.
This cleans that up and moves all of our scripts that invoke
javascript to be on the same plan. They invoke our specially named
node with a relative path to the JS code we want to run.
We no longer have a node_modules folder in the SDK (since all
packages now come from NPM) so we need to adjust the shell script we
use to launch our runner to use a relative path.
This addresses pulumi/pulumi#446: what we used to call "package" is
now called "project". This has gotten more confusing over time, now
that we're doing real package management.
Also fixespulumi/pulumi#426, while in here.
This improves the failure messages in two circumstances:
1) If the resource monitor RPC connection is missing. This can happen
two ways: either you run a Pulumi program using vanilla Node.js, instead
of the CLI, or you've accidentally loaded the Pulumi SDK more than once.
2) Failure to load the custom Pulumi SDK Node.js extension. This is a new
addition and would happen if you tried running a Pulumi program using a
vanilla Node.js, rather than using the Pulumi CLI.
