This improves a few things about assets:
* Compute and store hashes as input properties, so that changes on
disk are recognized and trigger updates (pulumi/pulumi#153).
* Issue explicit and prompt diagnostics when an asset is missing or
of an unexpected kind, rather than failing late (pulumi/pulumi#156).
* Permit raw directories to be passed as archives, in addition to
archive formats like tar, zip, etc. (pulumi/pulumi#240).
* Permit not only assets as elements of an archive's member list, but
also other archives themselves (pulumi/pulumi#280).
Instead of doing the logic to see if a type has YAML tags and then
dispatching based on that to use either the direct go-yaml marshaller
or the one that works in terms of JSON tags, let's just say that we
always add YAML tags as well, and use go-yaml directly.
This change adds functions, `pulumi.getProject()` and `pulumi.getStack()`,
to fetch the names of the project and stack, respectively. These can be
handy in generating names, specializing areas of the code, etc.
This fixespulumi/pulumi#429.
During the course of a `pulumi update`, it is possible for a resource to
become slated for deletion. In the case that this deletion is part of a
replacement, another resource with the same URN as the to-be-deleted
resource will have been created earlier. If the `update` fails after the
replacement resource is created but before the original resource has been
deleted, the snapshot must capture that the original resource still exists
and should be deleted in a future update without losing track of the order
in which the deletion must occur relative to other deletes. Currently, we
are unable to track this information because the our checkpoints require
that no two resources have the same URN.
To fix this, these changes introduce to the update engine the notion of a
resource that is pending deletion and change checkpoint serialization to
use an array of resources rather than a map. The meaning of the former is
straightforward: a resource that is pending deletion should be deleted
during the next update.
This is a fairly major breaking change to our checkpoint files, as the
map of resources is no more. Happily, though, it makes our checkpoint
files a bit more "obvious" to any tooling that might want to grovel
or rewrite them.
Fixes#432, #387.
A dynamic resource is a resource whose provider is implemented alongside
the resource itself. This provider may close over and use orther
resources in the implementation of its CRUD operations. The provider
itself must be stateless, as each CRUD operation for a particular
dynamic resource type may use an independent instance of the provider.
Changes to the definition of a resource's provider result in replacement
of the resource itself (rather than a simple update), as this allows the
old provider definition to delete the old resource and the new provider
definition to create an appropriate replacement.
If a plugin fails to load after we've set up the goroutines that copy
from its std{out,err} streams, then those goroutines can end up writing
to a closed event channel. This change ensures that we properly drain
those streams in this case.
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)
This changes a few things about "components":
* Rename what was previously ExternalResource to CustomResource,
and all of the related fields and parameters that this implies.
This just seems like a much nicer and expected name for what
these represent. I realize I am stealing a name we had thought
about using elsewhere, but this seems like an appropriate use.
* Introduce ComponentResource, to make initializing resources
that merely aggregate other resources easier to do correctly.
* Add a withParent and parentScope concept to Resource, to make
allocating children less error-prone. Now there's no need to
explicitly adopt children as they are allocated; instead, any
children allocated as part of the withParent callback will
auto-parent to the resource provided. This is used by
ComponentResource's initialization function to make initialization
easier, including the distinction between inputs and outputs.
This change implements core support for "components" in the Pulumi
Fabric. This work is described further in pulumi/pulumi#340, where
we are still discussing some of the finer points.
In a nutshell, resources no longer imply external providers. It's
entirely possible to have a resource that logically represents
something but without having a physical manifestation that needs to
be tracked and managed by our typical CRUD operations.
For example, the aws/serverless/Function helper is one such type.
It aggregates Lambda-related resources and exposes a nice interface.
All of the Pulumi Cloud Framework resources are also examples.
To indicate that a resource does participate in the usual CRUD resource
provider, it simply derives from ExternalResource instead of Resource.
All resources now have the ability to adopt children. This is purely
a metadata/tagging thing, and will help us roll up displays, provide
attribution to the developer, and even hide aspects of the resource
graph as appropriate (e.g., when they are implementation details).
Our use of this capability is ultra limited right now; in fact, the
only place we display children is in the CLI output. For instance:
+ aws:serverless:Function: (create)
[urn=urn:pulumi:demo::serverless::aws:serverless:Function::mylambda]
=> urn:pulumi:demo::serverless::aws:iam/role:Role::mylambda-iamrole
=> urn:pulumi:demo::serverless::aws:iam/rolePolicyAttachment:RolePolicyAttachment::mylambda-iampolicy-0
=> urn:pulumi:demo::serverless::aws:lambda/function:Function::mylambda
The bit indicating whether a resource is external or not is tracked
in the resulting checkpoint file, along with any of its children.
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.
This change adds the capability for a resource provider to indicate
that, where an action carried out in response to a diff, a certain set
of properties would be "stable"; that is to say, they are guaranteed
not to change. As a result, properties may be resolved to their final
values during previewing, avoiding erroneous cascading impacts.
This avoids the ever-annoying situation I keep running into when demoing:
when adding or removing an ingress rule to a security group, we ripple
the impact through the instance, and claim it must be replaced, because
that instance depends on the security group via its name. Well, the name
is a great example of a stable property, in that it will never change, and
so this is truly unfortunate and always adds uncertainty into the demos.
Particularly since the actual update doesn't need to perform replacements.
This resolvespulumi/pulumi#330.
`deploy.Plan.Apply` was only consumed by the engine, and seemed to be in
the wrong place given the API exported by the rest of `Plan` (i.e.
`Plan.Start` + `PlanIterator`). Furthermore, we were missing a reasonable
opportunity to share code between `update` and `preview`, both of which
need to walk the plan. These changes move the plan walk into `package engine`
as `planResult.Walk` and replace the `Progress` interface with a new interface,
`StepActions`, which subsumes the functionality of the former and adds support
for implementation-specific step execution. `planResult.Walk` is then
consumed by both `Engine.Deploy` and `Engine.PrintPlan`.
This change enables us to make progress on exposing data sources
(see pulumi/pulumi-terraform#29). The idea is to have an Invoke
function that simply takes a function token and arguments, performs
the function lookup and invocation, and then returns a return value.
Print "modified" rather than "modifyd". This introduces a new method,
`resource.StepOp.PastTense()`, which returns the past tense description
of the operation.
This change improves our output formatting by generally adding
fewer prefixes. As shown in pulumi/pulumi#359, we were being
excessively verbose in many places, including prefixing every
console.out with "langhost[nodejs].stdout: ", displaying full
stack traces for simple errors like missing configuration, etc.
Overall, this change includes the following:
* Don't prefix stdout and stderr output from the program, other
than the standard "info:" prefix. I experimented with various
schemes here, but they all felt gratuitous. Simply emitting
the output seems fine, especially as it's closer to what would
happen if you just ran the program under node.
* Do NOT make writes to stderr fail the plan/deploy. Previously
we assumed that any console.errors, for instance, meant that
the overall program should fail. This simply isn't how stderr
is treated generally and meant you couldn't use certain
logging techniques and libraries, among other things.
* Do make sure that stderr writes in the program end up going to
stderr in the Pulumi CLI output, however, so that redirection
works as it should. This required a new Infoerr log level.
* Make a small fix to the planning logic so we don't attempt to
print the summary if an error occurs.
* Finally, add a new error type, RunError, that when thrown and
uncaught does not result in a full stack trace being printed.
Anyone can use this, however, we currently use it for config
errors so that we can terminate with a pretty error message,
rather than the monstrosity shown in pulumi/pulumi#359.
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.
Instead of binding on 0.0.0.0 (which will listen on every interface)
let's only listen on localhost. On windows, this both makes the
connection Just Work and also prevents the Windows Firewall from
blocking the listen (and displaying UI saying it has blocked an
application and asking if the user should allow it)
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.
This change finishes the conversion of LUMIDL over to the new
runtime model, with the appropriate code generation changes.
It turns out the old model actually had a flaw in it anyway that we
simply didn't hit because we hadn't been stressing output properties
nearly as much as the new model does. This resulted in needing to
plumb the rejection (or allowance) of computed properties more
deeply into the resource property marshaling/unmarshaling logic.
As of these changes, I can run the GitHub provider again locally.
This change fixespulumi/pulumi-fabric#332.
This change upgrades gRPC to 1.6.0 to pick up a few bug fixes.
We also use the full address for gRPC endpoints, including the
interface name, as otherwise we pick the wrong interface on Linux.
There's a fair bit of clean up in here, but the meat is:
* Allocate the language runtime gRPC client connection on the
goroutine that will use it; this eliminates race conditions.
* The biggie: there *appears* to be a bug in gRPC's implementation
on Linux, where it doesn't implement WaitForReady properly. The
behavior I'm observing is that RPC calls will not retry as they
are supposed to, but will instead spuriously fail during the RPC
startup. To work around this, I've added manual retry logic in
the shared plugin creation function so that we won't even try
to use the client connection until it is in a well-known state.
pulumi/pulumi-fabric#337 tracks getting to the bottom of this and,
ideally, removing the work around.
The other minor things are:
* Separate run.js into its own module, so it doesn't include
index.js and do a bunch of random stuff it shouldn't be doing.
* Allow run.js to be invoked without a --monitor. This makes
testing just the run part of invocation easier (including
config, which turned out to be super useful as I was debugging).
* Tidy up some messages.
If a resource's planning operation is to do nothing, we can safely
assume that all of its properties are stable. This can be used during
planning to avoid cascading updates that we know will never happen.
This change adds the ability to perform runtime logging, including
debug logging, that wires up to the Pulumi Fabric engine in the usual
ways. Most stdout/stderr will automatically go to the right place,
but this lets us add some debug tracing in the implementation of the
runtime itself (and should come in handy in other places, like perhaps
the Pulumi Framework and even low-level end-user code).
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.
This change simplifies the provider RPC interface slightly:
1) Eliminate Get. We really don't need it anymore. There are
several possibly-interesting scenarios down the road that may
demand it, but when we get there, we can consider how best to
bring this back. Furthermore, the old-style Get remains mostly
incompatible with Terraform anyway.
2) Pass URNs, not type tokens, across the RPC boundary. This gives
the provider access to more interesting information: the type,
still, but also the name (which is no longer an object property).
This helps avoid running into file handle limits when creating archives including thousands of node_modules files.
Tracking a more complete fix through all other codepaths related to assets as part of #325.
This change ensures we close all Blobs in the asset/archive logic.
In particular, the archive.Read function returns a map of files to
Blobs and after we are done copying the contents we must ensure
that we invoke Close, otherwise we may leak file handles, sockets,
and so on. This may or may not be the culprit to the "too many
files open" errors we are hitting while deploying the M5 bits.
This changes a few things in the CLI, mostly just prettying it up:
* Label all steps more clearly with the kind of step. Also
unify the way we present this during planning and deployment.
* Summarize the changes that *did not* get made just as clearly
as those that did. In other words, stuff like this:
info: 2 resources changed:
+1 resource created
-1 resource deleted
5 resources unchanged
and
info: no resources required
5 resources unchanged
* Always print output properties when they are pertinent.
This includes creates, replacements, and updates.
* Show replacement creates and deletes very distinctly. The
create parts show up minty green and the delete parts show up
rosey red. These are the "physical" steps, compared to the
"logical" step of replacement (which remains marigold).
I still don't love where we are here. The asymmetry between
planning and deployment bugs me, and could be surprising.
("Hey, my deploy doesn't look like my plan!") I don't know
what developers will want to see here and I feel like in
general we are spewing far too much into the CLI to make it
even useful for anything but diagnosing failures afterwards.
I propose that we should do a deep dive on this during the
CLI epic, pulumi/pulumi-service#2.
This resolvespulumi/pulumi-fabric#305.
At the moment, we permit resources to carry a name, which the
engine uses as part of URN creation. Unfortunately, the property
"name" has a very high chance of conflicting with meaningful
user-authored properties. And furthermore this sort of name,
although key to creating URNs which are core to how the overall
system performs deployments and manages resources, are seldom
used programmatically in Lumi programs. As a result, it's a real
nuisance that we stole the good name.
This change renames that property from "name" to "urnName". This
not only has a lower likelihood of conflicting, but it also looks
reasonable sitting alongside the "urn" property. In fact, in some
future universe, after some of the upcoming runtime changes, we
may not even need the name property on the objects whatsoever.
I had originally toyed with the idea of eliminating the Resource
versus NamedResource distinction. This is certainly simpler and
remains a possibility. I didn't do that right now, however, because
the flexibility of letting resource providers name resources however
they see fit still seems possibly useful. For example, we keep
talking about whether functions can be auto-named based on hashes.
Until we've run those conversations to ground, I'd hate to do some
work that just needs to be undone in order to enable a scenario that
has a non-trivial likelihood of us wanting to explore.
We are now freely flowing computed and output properties across the
RPC boundary with providers. As such, we need to tolerate them in
a few more places. Namely, mapping to and from regular non-resource
property values, and also when copying RPC resource state back onto
live runtime objects.
We are renaming Lumi to Pulumi Fabric. This change simply renames the
pulumi/lumi repo to pulumi/pulumi-fabric, without the CLI tools and other
changes that will follow soon afterwards.
This changes the RPC interfaces between Lumi and provider ever so
slightly, so that we can track default properties explicitly. This
is required to perform accurate diffing between inputs provided by
the developer, inputs provided by the system, and outputs. This is
particularly important for default values that may be indeterminite,
such as those we use in the bridge to auto-generate unique IDs.
Otherwise, we fail to reapply defaults correctly, and trick the
provider into thinking that properties changed when they did not.
This is a small step towards pulumi/lumi#306, in which we will defer
even more responsibility for diffing semantics to the providers.
This change serializes unknown properties anywhere in the entire
property structure, including deeply embedded inside object maps, etc.
This is now done in such a way that we can recover both the computed
nature of the serialized property, along with its expected eventual
type, on the other side of the RPC boundary.
This will let us have perfect fidelity with the new bridge's view on
computed properties, rather than special casing them on "one side".
For Update and Delete operations, we provided just the input state
for a resource. This is insufficient, because the provider may need
to depend on output state from the Create or prior Update operations.
This change merges the output atop the input during the step application.
As part of the bridge bringup, I've discoverd that the property state
returned from Creates does *not* always equal the state that is then
read from calls to Get. (I suspect this is a bug and that they should
be equivalent, but I doubt it's fruitfal to try and track down all
occurrences of this; I bet it's widespread). To cope with this, we will
return state from Create and Update, instead of issuing a call to Get.
This was a design we considered to start with and frankly didn't have
a super strong reason to do it the current way, other than that it seemed
elegant to place all of the Get logic in one place.
Note that providers may choose to return nil, in which case we will read
state from the provider in the usual Get style.
This change mirrors the dynamic marshaling structure on the static
definition of the Asset and Archive types. This ensures that they
marshal correctly even when deeply embedded inside other structures.
This change brings the same typed serialization we use for RPC
to the serialization of deployments. This ensures that we get
repeatable diffs from one deployment to the next.
This reverts commit c3db70849d.
I've opted to take a new strategy to ensure the bridge properties
don't conflict (with manual renames), similar to the name property.
This change recognizes assets and archives as 1st class resource
property values. This is necessary to support them in the new bridge
work, and lays the foundation for fixing pulumi/lumi#153.
I also took the opportunity to clean up some old cruft in the
resource properties area.
This renames the basemost resource properties, id and urn, to
names that are less likely to conflict with properties that real
resources will want to use, pid and upn (provider ID and Universal
Pulumi Name, respectively).
I actually ran into this with the current bridge work. An alternative
solution would be to require derived resources to pick different names,
however this is unfortunate because usually they are more "user-facing"
than ours. Another alternative is to not hijack the object properties
at all, but that too is problematic because we use these properties
during the evaluation of plans and deployments.
This seems like a reasonable middle ground.
This adds a ReadLocations RPC function to the engine interface, alongside
the singular ReadLocation. The plural function takes a single token that
represents a module or class and we will then return all of the module
or class (static) properties that are currently known.
This adds a handy MapReplace function on pkg/resource's PropertyMap and
PropertyValue types. This is just like the existing Mappable function,
except that it permits easy replacement of elements as the map transformation
occurs. We need this to perform float64=>int transformations.
We fail very late in the process of plan application, should a duplicate
URN arise. This change fails as early in the process as possible and
ensures that it does so with good line number information.
This properly unwinds the interpreter should something happen that
results in cancellation. This occurs, for example, when the planning
engine encounters an error and decides that it doesn't need to proceed
further with evaluation before it simply goes ahead and exits.
This adds a few missing closes for the plugin host/context. This
should fixpulumi/lumi#261. Eventually when we have more robust
nightly test options, and want to spend the time, we should think
about doing more rigorous stress testing that kills processes at
inopportune times and guarantees we don't leak. I've filed
pulumi/lumi#263 to do that.
This change fixes a few things:
* Most importantly, we need to place a leading "." in the paths
to Gometalinter, otherwise some sub-linters just silently skip
the directory altogether. errcheck is one such linter, which
is a very important one!
* Use an explicit Gometalinter.json file to configure the various
settings. This flips on a few additional linters that aren't
on by default (line line length checking). Sadly, a few that
I'd like to enable take waaaay too much time, so in the future
we may consider a nightly job (this includes code similarity,
unused parameters, unused functions, and others that generally
require global analysis).
* Now that we're running more, however, linting takes a while!
The core Lumi project now takes 26 seconds to lint on my laptop.
That's not terrible, but it's long enough that we don't want to
do the silly "run them twice" thing our Makefiles were previously
doing. Instead, we shall deploy some $$($${PIPESTATUS[1]}-1))-fu
to rely on the fact that grep returns 1 on "zero lines".
* Finally, fix the many issues that this turned up.
I think(?) we are done, except, of course, for needing to drive
down some of the cyclomatic complexity issues (which I'm possibly
going to punt on; see pulumi/lumi#259 for more details).
We were not propagating the error from `deployLatest` through
to the CLI error result. Despite out recent efforts to integrate
gometalinter, there were also several additional similar cases of
ignored error results reported by `errcheck`. Not yet clear why
these are not being reported via gometalinter.
Fixes#262.
After 233c5a8 landed, I noticed there are a few things to be fixed up:
* Run gometalinter in all the right places. We need to run both in
lint and lint_quiet targets. I've also cleaned up some of the logic
around what to suppress so there's less repetition.
* We currently @ meaningful commands, which is unfortunate, since it
makes debugging Makefiles tough (especially when looking at CI build
logs). Going forward, we should only use @ for meaningless commands,
like @echo.
* The AWS project wasn't actually running tslint, because it needs to
say `tslint './pack/**/*.ts' --exclude='./pack/node_modules/**'`.
The current script of `tslint lib/aws/pack/...` wasn't actually
running lint, hence we missed a lot of AWS lint issues.
* Fix up the issues that these fixes uncovered. Mostly err shadowing.
This continues the previous commit and establishes the interpreter
context so that we can use the new host interface. In summary:
* Instead of using the NullSource for destructions -- which
doesn't hook up an interpreter and so any reads of configuration
variables will fail -- we will enlighten the EvalSource to know
how to orchestrate destruction interpretation. The primary
difference is that we don't actually run the code, but *we do*
perform all of the necessary configuration and variable init.
* Associate the active interpreter with the plugin context as
we are executing, so that the host object can actually read the
state from the heap as requested to do so by attached plugins.
* Rename anything "engine" related to use the term "host"; this
avoids introducing unnecesarily new terminology.
* Add a new pkg/resource/provider/ package where we can begin
consolidating helper functionality for resource providers.
Right now, this includes a wrapper interface atop the gRPC
machinery necessary to contact the host, in addition to a
Main function that hides some boilerplate entrypoint code.
* Add a rpcutil.IsBenignCloseErr routine to let us ignore
"benign" gRPC errors that are knowingly returned at shutdown.
This commit completes pulumi/lumi#117.
This addresses CR feedback from @lukehoban; namely, that we should
be going through the Read API for location reads in the plugin host
to ensure that getters are invoked as appropriate.
I also made Location's various fields private so that we aren't
tempted to make this mistake elsewhere, effectively "forcing" us
to go through the accessor methods.
This change adds an engine gRPC interface, and associated implementation,
so that plugins may do interesting things that require "phoning home".
Previously, the engine would fire up plugins and talk to them directly,
but there was no way for a plugin to ask the engine to do anything.
The motivation here is so that plugins can read evaluator state, such
as config information, but this change also allows richer logging
functionality than previously possible. We will still auto-log any
stdout/stderr writes; however, explicit errors, warnings, informational,
and even debug messages may be written over the Log API.
This change implements the `get` function for resources. Per pulumi/lumi#83,
this allows Lumi scripts to actually read from the target environment.
For example, we can now look up a SecurityGroup from its ARN:
let group = aws.ec2.SecurityGroup.get(
"arn:aws:ec2:us-west-2:153052954103:security-group:sg-02150d79");
The returned object is a fully functional resource object. So, we can then
link it up with an EC2 instance, for example, in the usual ways:
let instance = new aws.ec2.Instance(..., {
securityGroups: [ group ],
});
This didn't require any changes to the RPC or provider model, since we
already implement the Get function.
There are a few loose ends; two are short term:
1) URNs are not rehydrated.
2) Query is not yet implemented.
One is mid-term:
3) We probably want a URN-based lookup function. But we will likely
wait until we tackle pulumi/lumi#109 before adding this.
And one is long term (and subtle):
4) These amount to I/O and are not repeatable! A change in the target
environment may cause a script to generate a different plan
intermittently. Most likely we want to apply a different kind of
deployment "policy" for such scripts. These are inching towards the
scripting model of pulumi/lumi#121, which is an entirely different
beast than the repeatable immutable infrastructure deployments.
Finally, it is worth noting that with this, we have some of the fundamental
underpinnings required to finally tackle "inference" (pulumi/lumi#142).
This change simplifies the generated Check interface for providers.
Instead of
Check(ctx context.Context, obj *T) ([]error, error)
where T is the resource type, we have
Check(ctx context.Context, obj *T, property string) error
This is done so that we can drive the calls to Check one property
at a time, allowing us to skip any that are computed. (Otherwise,
we may fail the verification erroneously.)
This has the added advantage that the Check implementations are
simpler and can simply return a single error. Furthermore, the
generated RPC code handles wrapping the result, so we can just do
return errors.New("bad");
rather than the previous reflection-laden junk
return resource.NewFieldError(
reflect.TypeOf(obj), awsservice.AWSResource_Property,
errors.New("bad"))
This change implements showing a summary of the current environment.
All you need to do is run
$ lumi env
and the current environment's information will be printed.
This makes it convenient to grab resource information that might be
required, for instance, to correlate with logs (e.g., lambda ARNs).
Eventually, as per pulumi/lumi#184, we want to print details about
all of the resources too.
Tests all of our commonly used examples.
Also sets test parallelism to 10 by default
since we are I/O bound on API calls to
the resource providers.
Also avoids using larger EC2 examples in
our samples so that we can keep our test
costs lower :-).
On the first turn, we want to distinguish between a coroutine
running that owns its turn, and a coroutine that knows it doesn't
own the turn and is simply awaiting its turn. The old Meet logic
wasn't quite right; instead, we'll have the caller tell us this.
