The code that calculated plugin sizes was incorrect; it would show the
total size consumed by all plugins, for each plugin, which is clearly
busted. We should compute each plugin's size from its own directory.
This change skips unknown IDs during read operations. This can happen
when a read is performed using the output property of another resource
during planning. This is intentionally supported via ID being an
Input<ID> and all we need to do for this to work correctly is skip the
actual provider RPC and the runtime will propagate unknown outputs as
usual.
This change lets plugin versions to float in two ways:
1) If a `pulumi plugin install` detects a newer version is available
already, there's no need to download and install the older version.
2) If the engine attempts to load a plugin at a particular version,
if a newer version is available, it will be accepted without error.
As part of this, we permit $PATH to have the final say when determining
which version to accept. That is, it can always override the choice.
Note that I highly suspect, in the limit, that we'll want to stop doing
this for major version incompatibilities. For now, since we don't
envision any such version changes imminently, this will suffice.
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.
This change wires up the new Read RPC method in such a manner that
Pulumi programs can invoke it. This is technically not required for
refreshing state programmatically (as in pulumi/pulumi#1081), however
it's a feature we had eons ago and have wanted since (see
pulumi/pulumi#83), and will allow us to write code like
let vm = aws.ec2.Instance.get("my-vm", "i-07043cd97bd2c9cfc");
// use any property from here on out ...
The way this works is simply by bridging the Pulumi program via its
existing RPC connection to the engine, much like Invoke and
RegisterResource RPC requests already do, and then invoking the proper
resource provider in order to read the state. Note that some resources
cannot be uniquely identified by their ID alone, and so an extra
resource state bag may be provided with just those properties required.
This came almost for free (okay, not exactly) and will come in handy as
we start gaining experience with reading live state from resources.
This commit changes two things about our resource model:
* Stop performing Pulumi Engine-side diffing of resource state.
Instead, we defer to the resource plugins themselves to determine
whether a change was made and, if so, the extent of it. This
manifests as a simple change to the Diff function; it is done in
a backwards compatible way so that we continue with legacy diffing
for existing resource provider plugins.
* Add a Read RPC method for resource providers. It simply takes a
resource's ID and URN, plus an optional bag of further qualifying
state, and it returns the current property state as read back from
the actual live environment. Note that the optional bag of state
must at least include enough additional properties for resources
wherein the ID is insufficient for the provider to perform a lookup.
It may, however, include the full bag of prior state, for instance
in the case of a refresh operation.
This is part of pulumi/pulumi#1108.
* Improve the error message arising from missing required configs for
resource providers
If the resource provider that we are speaking to is new enough, it will send
across a list of keys and their descriptions alongside an error
indicating that the provider we are configuring is missing required
config. This commit packages up the list of missing keys into an error
that can be presented nicely to the user.
* Code review feedback: renaming simplification and correcting errors in comments
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.
As part of the new identity model, we're going to use tagging on
stacks to record metadata, let's create a bag for that, as well as a
few well known tag names that map to metadata we know we'll want to set.
This change adds a Pulumi Cloud Console URL at the end of an update
that went through the Pulumi Cloud API. This is very basic, and is
meant to be just the beginning of adding more cross-linking to the
service. I'm still thinking through the phrasing to use here.
* Send structured errors across RPC boundaries
This brings us closer to gRPC best practices where we send structured
errors with error codes across RPC endpoints. The new "rpcerrors"
package can wrap errors from RPC endpoints, so RPC servers can attach
some additional context as to why a request failed.
* Code review feedback:
1. Rename rpcerrors -> rpcerror, better package name
2. Rename RPCError -> Error, RPCErrorCause -> ErrorCause, names
suggested by gometalinter to improve their package-qualified names
3. Fix import organization in rpcerror.go
This endpoint is relatively expensive, as it returns a large amount of
data for each stack (essentially the stack's entire checkpoint). We
currently call this endpoint in a few places that really just need
information about a single stack. In these places we should simply
interact with that stack directly.
After these changes, there is only one call to the `stacks` endpoint on
the startup path: `upgradeConfigurationFiles` loops over all of the
stacks in each backend and attempts to upgrade each stack's
configuration. Once we no longer need to do this we will not be hitting
the `stacks` endpoint on each CLI invocation.
This change includes a bunch of refactorings I made in prep for
doing refresh (first, the command, see pulumi/pulumi#1081):
* The primary change is to change the way the engine's core update
functionality works with respect to deploy.Source. This is the
way we can plug in new sources of resource information during
planning (and, soon, diffing). The way I intend to model refresh
is by having a new kind of source, deploy.RefreshSource, which
will let us do virtually everything about an update/diff the same
way with refreshes, which avoid otherwise duplicative effort.
This includes changing the planOptions (nee deployOptions) to
take a new SourceFunc callback, which is responsible for creating
a source specific to the kind of plan being requested.
Preview, Update, and Destroy now are primarily differentiated by
the kind of deploy.Source that they return, rather than sprinkling
things like `if Destroying` throughout. This tidies up some logic
and, more importantly, gives us precisely the refresh hook we need.
* Originally, we used the deploy.NullSource for Destroy operations.
This simply returns nothing, which is how Destroy works. For some
reason, we were no longer doing this, and instead had some
`if Destroying` cases sprinkled throughout the deploy.EvalSource.
I think this is a vestige of some old way we did configuration, at
least judging by a comment, which is apparently no longer relevant.
* Move diff and diff-printing logic within the engine into its own
pkg/engine/diff.go file, to prepare for upcoming work.
* I keep noticing benign diffs anytime I regenerate protobufs. I
suspect this is because we're also on different versions. I changed
generate.sh to also dump the version into grpc_version.txt. At
least we can understand where the diffs are coming from, decide
whether to take them (i.e., a newer version), and ensure that as
a team we are monotonically increasing, and not going backwards.
* I also tidied up some tiny things I noticed while in there, like
comments, incorrect types, lint suppressions, and so on.
We previously locked our dependency on google.golang.org/grpc to 1.7.2 due to issues we had seen on 1.8.x as noted in #701. However, this has prevented us using some other dependencies which require newer grpc. A test in this repo and AWS showed no problems with the latest 1.10.x versions of the library in our tests.
We'll go ahead and remove this constraint and allow grpc to float forward. If we see issues again, we'll use that repro case to investigate an alternative fix in our code.
Resolves#701.
These changes add the API types and cloud backend code necessary to
interact with service-managed stacks (i.e. stacks that do not have
PPC-managed deployments). The bulk of these changes are unremarkable:
the API types are straightforward, as are most of the interactions with
the new APIs. The trickiest bits are token and log management.
During an update to a managed stack, the CLI must continually renew the
token used to authorize the operations on that stack that comprise the
update. Once a token has been renewed, the old token should be
discarded. The CLI supports this by running a goroutine that is
responsible for both periodically renewing the token for an update and
servicing requests for the token itself from the rest of the backend.
In addition to token renewal, log output must be captured and uploaded
to the service during an update to a managed stack. Implementing this in
a reasonable fashion required a bit of refactoring in order to reuse
what already exists for the local backend. Each event-specific `Display`
function was replaced with an equivalent `Render` function that returns
a string rather than writing to a stream. This approach was chosen
primarily to avoid dealing with sheared colorization tags, which would
otherwise require clients to fuse log lines before colorizing. We could
take that approach in the future.
These changes refactor direct interactions with the Pulumi API out of
the cloud backend and into a subpackage, `pkg/backend/cloud/client`.
This package exposes a slightly higher-level API that takes care of
calculating paths, performing HTTP calls, and occasionally wrapping
multiple physical calls into a single logical call (notably the creation
of an update and the upload of its program).
This is primarily intended as preparation for some of the changes
suggested in the feedback for #1067.
We needed to have two types of `UpdateProgramRequest` to serve both newer shapes of Pulumi configuration values as well as the older, untyped version. (The original change was supporting the `ConfigValue` type, which had a flag to indiciate if the configuration value was encrypted or not.)
Now that LM has been migrated to the M10 bits https://github.com/pulumi/home/issues/168 , we can remove this type. (The PR to remove existing references in the `pulumi-service` repo is https://github.com/pulumi/pulumi-service/pull/957.)
Just a nit: It's possible (though, unlikely) that the repo file is
deleted between the call to `os.Stat` and `ioutil.ReadFile`. Instead,
just try to read the file -- if the file doesn't exist,
`ioutil.ReadFile` will return an error that works the same with
`os.IsNotExist(err)` as the error returned from `os.Stat`.
Note: This is a minor issue that I didn't get to for M11 that isn't
required for M11 and would be fine merging for post-M11.
When you specify a template name explicitly (e.g.
`pulumi new typescript`), we'll try to download the template tarball
without first downloading the JSON list of available templates. The JSON
includes a description used when replacing the `${DESCRIPTION}` string
in template files. Since we didn't download the JSON, we won't have a
description, so we fallback to a default value (`"A Pulumi project."`).
This also happens when specifying `--offline` to use an existing
template under `~/.pulumi/templates`; we won't have a description for
the template, so we fallback to a default description. The fallback
value happens to be the same as the description for each of our current
templates, so noone will currently notice an issue.
For M11, I included initial support for a template manifest file where
the description (and any future metadata) could be stored, but didn't go
as far as actually reading the file.
This change makes it so the CLI actually reads the description from the
manifest file (if it exists), otherwise falling back to the default
value as is done currently. Some minor related cleanup is included in
this change.
This change uses the prior checkpoint's deployment manifest to pre-
populate all plugins required to complete the destroy operation. This
allows for subsequent attempts to load a resource's plugin to match the
already-loaded version. This approach obviously doesn't work in a
hypothetical future world where plugins for the same resource provider
are loaded side-by-side, but we already know that.
Also, rename/cleanup a bunch of serialization code.
Also, generate better environment names in the serialized closure code. Thsi code should be much easier to make sense of as hte names will better track to the original names in the user code.
Also, dedupe simple non-capturing functions. This helps ensure we don't spit out N copies of __awaiter (one per file it is declared in).
This takes the existing `apitype.Checkpoint` type and renames it to
`apitype.CheckpointV1` locking in the shape. In addition, we introduce
a `apitype.VersionedCheckpoint` type, which holds a version number and
a json document representing a checkpoint at that version. Now, when
reading a checkpoint, the CLI can determine if it's in a format it
understands, and fail gracefully if it is not.
While the CLI understands the older checkpoint version, it always
writes the newest version format, meaning that if you manage a
fire-and-forget stack with this version of the CLI, it will be
un-readable by previous versions.
Stacks managed by Pulumi.com are not impacted by this change.
Fixes: #887
* Improve error messages output by the CLI
This fixes a couple known issues with the way that we present errors
from the Pulumi CLI:
1. Any errors from RPC endpoints were bubbling up as they were to
the top-level, which was unfortunate because they contained
RPC-specific noise that we don't want to present to the user. This
commit unwraps errors from resource providers.
2. The "catastrophic error" message often got printed twice
3. Fatal errors are often printed twice, because our CLI top-level
prints out the fatal error that it receives before exiting. A lot of
the time this error has already been printed.
4. Errors were prefixed by PU####.
* Feedback: Omit the 'catastrophic' error message and use a less verbose error message as the final error
* Code review feedback: interpretRPCError -> resourceStateAndError
* Code review feedback: deleting some commented-out code, error capitalization
* Cleanup after rebase
This adds a `pulumi new` command which makes it easy to quickly
automatically create the handful of needed files to get started building
an empty Pulumi project.
Usage:
```
$ pulumi new typescript
```
Or you can leave off the template name, and it will ask you to choose
one:
```
$ pulumi new
Please choose a template:
> javascript
python
typescript
```
We were not colorizing a summary in one case. Also, there were
codepaths that would print to the console without first calling
spinner.Reset(), so the spinner would not be cleared from the screen.
When a stack has secrets, we now take the secret values and construct
a regular expression which is just an alternation of all the secret
values. Then, before pushing any string data into an Event, we run the
regular expression and replace all matches with '[secret]'.
Fixes#747
The engine now emits events with richer metadata during the
ResourceOutputs and ResourcePre callbacks. The CLI can then use this
information to decide if it should display the event or not and how
much of the event to display.
Options dealing with what to display and how to display it have moved
into the CLI and the engine now emits all information for each event.
