This makes two minor tweaks to the login prompt:
1. Change the text so that it hyperlinks in most terminals, including
iTerm, in a way that doesn't include excess characters.
2. Disable echoing of the token.
A previous change altered the calculation of plugin sizes broke the
ability to install plugins that weren't backed by a directory. This
fixes that by making getPluginSize act correctly for any kind of path.
Due to an interaction between pointers and go's `range` operator, we
would end up always returning the last plugin in a user's plugin
cache, instead of the right value.
We now save the current plugin into a local, so if we end up taking
the address the right thing will happen.
Fixes#1196
* Lift snapshot management out of the engine
This PR is a prerequisite for parallelism by addressing a major problem
that the engine has to deal with when performing parallel resource
construction: parallel mutation of the global snapshot. This PR adds
a `SnapshotManager` type that is responsible for maintaining and
persisting the current resource snapshot. It serializes all reads and
writes to the global snapshot and persists the snapshot to persistent
storage upon every write.
As a side-effect of this, the core engine no longer needs to know about
snapshot management at all; all snapshot operations can be handled as
callbacks on deployment events. This will greatly simplify the
parallelization of the core engine.
Worth noting is that the core engine will still need to be able to read
the current snapshot, since it is interested in the dependency graphs
contained within. The full implications of that are out of scope of this
PR.

We've seen failures in CI where DNS lookups fail which cause our
operations against the service to fail, as well as other sorts of
timeouts.
Add a set of helper methods in a new httputil package that helps us do
retries on these operations, and then update our client library to use
them when we are doing GET requests. We also provide a way for non GET
requests to be retried, and use this when updating a lease (since it
is safe to retry multiple requests in this case).
The RPC provider interface needs a way to convey back to the engine
that a resource being read no longer exists. To do this, we'll return
the ID property that was read back. If it is empty, it means the
resource is gone. If it is non-empty, we expect it to match the input.
We might create an AWS session with one set of credentials, cache it, then
return it when a later caller asked for a session with *different* creds.
Instead, just cache one default session and Copy other sessions from it.
Less important in the CLI, but critical when the engine is used as a library
in a long-running process.
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.
I believe because of the way we have structured the code, it is
impossible to know a resource's parent but not printed it. I've
changed the test which would print the parent resource to an assert
that ensure we have printed it.
The next commit is going to remove the shown array because we no
longer need it, but this commit is here so that if there are display
bugs as part of the larger refactoring in how we display events, we
can bisect back and see this failure.
The `shouldShow` method always marked a step as seen, and having the
side effect there is a little confusing. Because we call shouldShow in
the StepPre, StepPost and Output handlers, its also hard to ensure an
invarant I think we want, which is that in the Post and Output
handlers, we've already seen the event.
So, let's move the marking out of `shouldShow` and into
`OnResourceStepPre` and then assert we've already seen it in
`OnResourceStepPre` and `OnResourceOutputs` handlers.
This means that shouldShow is now a pure function and makes it easier
to move the decision on if we should print information about a step
out of the engine and into the CLI.
As it stands, we allow plugin load requests to race. Not only does this
create a situation in which we may load and then immediately throw away
a plugin (potentially leaking its process), it also creates the
possibility of races when reading from/writing to the various plugin
caches. These changes serialize all plugin loads and cache accesses by
running all accesses for a particular host in a single goroutine.
Fixes#1020.
The engine now unconditionally emits a new type of event, a
PreludeEvent, which contains the configuration for a stack as well as
an indication if the stack is being previewed or updated. The
responsibility for interpreting the --show-config flag on the command
line is now handled by the CLI, which uses this to decide if it should
print the configuration or not, and then writes the "Previewing
changes" or "Deploying chanages" header.
This value was unused across all of our display code. We did thread it
everywhere, but we never actually used the value to make any
decisions. Since we want to move to a model where the engine does not
decide *what* to display, it's helpful to remove this policy stuff
anyway.
This helper method is only really used for testing, but we should not
allow it to create a Key who's namespace has a colon (as ParseKey
would not build something like this).
This API was introduced to aid the refactoring, but it isn't something
we want to support long term. Remove it and for a few places, push
passing config.Key around more, instead of converting to the old type
eagerly.
When serializing config.Key's we now write them as <package>:<name>
instead of <package>:config:<name>. We continue to support reading the
older format for compatability with older files.
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>`).
I'll be changing the structure of the representation of config.Key, so
let's write some tests first to ensure we can continue to treat
everything as JSON and YAML.
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.
The change to refactor out where we store configuration data broke our
old strategy, which we discovered when we tried to take this payload
into pulumi-aws.
As it stands, we only configure those providers for which configuration
is present. This can lead to surprising failure modes if those providers
are then used to create resources. These changes ensure that all
resource providers that are not configured during plan initialization
are configured upon first load.
Fixes#758.
By using untyped deployment structures via `json.RawMessage`, we can
support round-tripping between old CLI clients and newer servers, without
dropping possibly-important information on the floor. I hadn't realized
this design goal with the original system, and after talking to @pgavlin,
I better realized the intent and that we want to preserve this.
The filenames we used to store history data locally only had second
level precision. On my machine, the test history test is able to run
multiple `pulumi update` commands in the same second, which causes a
newer history file to overwrite an older one.
This change moves to using a nanosecond precision timestamp when
writing config. In addition, the CLI was trying to sort the updates
that came back from the backend (instead of just trusting them to be
in newest first order, as we documented) so I removed that code as
well.
Make many fixes to closure serialization
Primary things that i've done as part of this change:
Added support for cyclic objects.
Properly serialize objects that are shared across different function. previously you would get multiple copies, now you properly reference the same copy.
Remove the usages of 'hashes' for functions. Because we track identity of objects, we no longer need them.
Serialize properties of functions (if they have any).
Handle Objects/Functions with different __proto__s than normal. i.e. classes/constructors. but also anything the user may have done themselves to the object.
Handle generator functions.
Handle functions with 'computed' names.
Handle functions with 'symbol' names.
Handle serializing Promises as Promises.
Removed the dual Closure/AsyncClosure tree. One existed solely so we could have a tree without promises (for use in testing maybe?). Because this all exists in a part of our codebase that is entirely async, it's fine to have promises in the tree, and to await them when serializing the Closure to a string.
Handle serializing class-constructors and methods. Including properly handling 'super' calls.
A hold-over from a previous experiment (LumiIDL) which we don't use
anymore. If we decide to bring that back, we can easily restore these
types, but for now, let's just remove this dead code.
Most of the errors in this package are holdovers from our previous
syetem where we had our own custom compiler and evaluator and are no
longer needed. The few we still use during plan applicaton (via the
diagnostics system, which is another component from the old system
that we still use) have been promoted into the diag package. Doing so,
allows us to not have to import "github.com/pkg/errors" as "goerr" in
some parts of the engine, a nice cleaup.
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.
Despite our good progress moving towards having an apitype package,
where our exchange types live and can be shared among the engine and
our services, there were a few major types that were still duplciated.
Resource was the biggest example -- and indeed, the apitype varirant
was missing the new Dependencies property -- but there were others,
like Manfiest, PluginInfo, etc. These too had semi-random omissions.
This change merges all of these types into the apitype package. This
not only cleans up the redundancy and missing properties, but will
"force the issue" with respect to keeping them in sync and properly
versioning the information in a backwards compatible way.
The resource/stack package still exists as a simple marshaling layer
to and from the engine's core data types.
Finally, I've made the controversial change to share the actual
Deployment data structure at the apitype layer also. This will force
us to confront differences in that data structure similarly, and will
allow us to leverage the strong typing throughout to catch issues.
Previously, we would prefer a plugin on the $PATH which is more or
less always the case for people hacking on `pulumi`. Later, when we
went to check the loaded plugin version matched the one we requested,
we fail.
Now, if we have a version, we'll first consult the local plugin
cache. If that fails, we'll fall back to the $PATH as we used to.
When we are loading a plugin without a version, we continue to use the
one on the $PATH (without testing the cache) on the assumption it is
newer.
In addition, we've turned the "plugin versions are mis-matched" from
an error into a warning. We expect that we'll only ever see this
warning when something strange is going on (since in the normal case,
we'll have found the exact version in the cache) but having it not
hard fail does help in development cases.
Fixes#977
The spinner code used \b, but didn't overwrite with spaces, so part
of the message could get left behind when other writes to stdout/err
occurred. This change simply overwrites characters with spaces.
This change gets enough of the Python SDK up and running that the
empty Python program will work. Mostly just scaffolding, but the
basic structure is now in place. The primary remaining work is to
wire up resource creation to the gRPC interfaces.
In summary:
* The basic structure is as follows:
- Everything goes into sdk/python/.
- sdk/python/cmd/pulumi-langhost-python is a Go language host
that simply knows how to spawn Python processes to run out
entrypoint in response to requests by the engine.
- sdk/python/cmd/pulumi-langhost-python-exec is a little Python
shim that is invoked by the language host to run Python programs,
and is responsible for setting up the minimal goo before we can
do so (RPC connections and the like).
- sdk/python/lib/ contains a Python Pip package suitable for PyPi.
- In there, we have two packages: the root pulumi package that
contains all of the basic Pulumi programming model abstractions,
and pulumi.runtime, which contains the implementation of
resource registration, RPC interfacing with the engine, and so on.
* Add logic in our test framework to conditionalize on the language
type and react accordingly. This will allow us to skip Yarn for
Python projects and eventually run Pip if there's a requirements.txt.
* Created the basic project structure, including all of the usual
Make targets for installing into the proper places.
* Building also runs Pylint and we are clean.
There are a few other minor things in here:
* Add an "empty" test for both Node.js and Python. These pass.
* Fix an existing bug in plugin shutdown logic. At some point, we
started waiting for stderr/stdout to flush before shutting down
the plugin; but if certain failures happen "early" during the
plugin launch process, these channels will never get initialized
and so waiting for them deadlocks.
* Recently we seem to have added logic to delete test temp
directories if a failure happened during initialization of said
temp directories. This is unfortunate, because you often need to
look at the temp directory to see what failed. We already clean
them up elsewhere after the full test completes successfully, so
I don't think we need to be doing this, and I've removed it.
Still many loose ends (config, resources, etc), but it's a start!
This change adds a basic Python langhost RPC server. It's fairly
barebones and merely acts as a jumping off point for the Pulumi engine
to spawn a Python program. The host is written in Go, in contrast to
implementing the host in Python, and more closely resembles how I
expect the Node.js language host to work once pulumi/pulumi#331 is done.
1. Output different-colored edges for parent-child resource
relationships
2. Allow the changing of edge colors via command-line parameters
3. Allow the skipping of the parent-child graph or the
dependency graph when calculating all edges
This modifies the Graph interface slightly to allow an edge to specify
what color should be used when drawing it.
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
Some file systems do not record BithTimes and BirthTime panics in
these cases. We use HasBirthTimes to guard against this and print n/a
when we do not have a BirthTime.
This change makes the engine backwards compatible with older
language host binaries, by simply ignoring GetRequiredPlugins
calls when the RPC server has not yet implemented it. This
is benign, since we will eventually fault plugins in on demand,
although it does mean that commands like `pulumi plugin install`
will become no-ops (which, thankfully, is what we want).
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.
Previously, the checkpoint manifest contained the full path to a plugin
binary, in places of its friendly name. Now that we must move to a model
where we install plugins in the PPC based on the manifest contents, we
actually need to store the name, in addition to the version (which is
already there). We still also capture the path for debugging purposes.
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.
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.
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 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.
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.
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.
We've seen yarn fail from time to time during our integration
tests (usually timeouts talking to the npm registry) so let's add a
few retries to all yarn commands.

Fixes#822
Resources in the checkpoint file which are pending-delete represent old versions of resources which are no longer part of the active deployment. For purposes of constructing the active resource tree, we should skip these resources.
As it stands, we currently hammer the service's update logs endpoint in
a tight loop while waiting for a deployment to complete. This is not
necessary, and can indeed be deletrious to the user experience: it
appears that this may be exacerbating some mysterious 500 responses from
API gateway.
These changes add a brief sleep in the relevant loop that waits for 5
seconds if the last call produced new log entries or 15 seconds if it
did not.
Fixes#844.
Today we don't send any version information with API requests to the service, so we cannot make breaking changes between versions of the backend API while preserving backwards compatibility.
This PR adds a `User-Agent` header with REST requests that sends a CLI version number of "1". If the service were to make a breaking change, it could use this header to determine which response handler to use. (e.g. return a different response for "" or "1" and another for "2".) Obviously we want to avoid being in this situation, but in the event that we need to make a breaking change, we'll need this value.
We send the Pulumi version as well, though the SDK will probably rev much more quickly than the backend API client version.
Fixes#848
We were pretty careful to keep the test directory around if the test ever
exited early due to a panic or error return. But if the test ran to
completion and failed -- for example, if ExtraRuntimeValidation caused the
test to fail -- we would end up deleting the test directory.
Fixes#868
Previously, when uploading a projectm to the service, we would only
upload the folder rooted by the Pulumi.yaml for that project. This
worked well, but it meant that customers needed to structure their
code in a way such that Pulumi.yaml was always as the root of their
project, and if they wanted to share common files between two projects
there was no good solution for doing this.
This change introduces an optional piece of metadata, named context,
that can be added to Pulumi.yaml, which allows controlling the root
folder used for computing the root folder to archive from. When it is
set, it is combined with the location of the Pulumi.yaml file for the
project we are uploading and that folder is uses as the root of what
we upload to the service.
Fixes: #574
The existing logic would flow colorization information into the
engine, so depending on the settings in the CLI, the engine may or may
not have emitted colorized events. This coupling is not great and we
want to start moving to a world where the presentation happens
exclusively at the CLI level.
With this change, the engine will always produce strings that have the
colorization formatting directives (i.e. the directives that
reconquest/loreley understands) and the CLI will apply
colorization (which could mean either running loreley to turn the
directives into ANSI escape codes, or drop them or retain them, for
debuging purposes).
Fixes#742
If we do not do this, the engine will assume that it should elide
unknown input/output properties when interacting with the language
and resource providers and we will produce unexpected results.
This PR adds a new `pulumi history` command, which prints the update history for a stack.
The local backend stores the update history in a JSON file on disk, next to the checkpoint file. The cloud backend simply provides the update metadata, and expects to receive all the data from a (NYI) `/history` REST endpoint.
`pkg/backend/updates.go` defines the data that is being persisted. The way the data is wired through the system is adding a new `backend.UpdateMetadata` parameter to a Stack/Backend's `Update` and `Destroy` methods.
I use `tests/integration/stack_outputs/` as the simple app for the related tests, hence the addition to the `.gitignore` and fixing the name in the `Pulumi.yaml`.
Fixes#636.
Previously, the `pulumi` tool did not show any indication of progress
when doing a deployment. Combined with the fact that we do not create
resources in parallel it meant that sometime `pulumi` would appear to
hang, when really it was just waiting on some resource to be created
in AWS. In addition, some AWS resources take a long time to create and
CI systems like travis will kill the job if there is no output. This
causes us (and our customers) to have to do crazy dances where we
launch shell scripts that write a dot to the console every once in a
while so we don't get killed. While we plan to overhaul the output
logic (see #617), we take a first step towards interactivity by simply
having a nice little spinner (in the interactive case) and when run
non interactive have `pulumi` print a message that it is still
working.
Fixes#794
This PR exports the aggregate resource changes for update and destroy operations. We'll use this information in #636 when summarizing previous updates.
I initially started with a new struct that had fields like `Created`, `Deleted`, `Unchanged`, etc. But it became cumbersome with the seven different type of resource operations we perform. So instead went with the more flexible `map[deploy.StepOp]int`.
Surprisingly `pulumi login -c https://google.com` would succeed. This was because we were too lax in our way of validating credentials. We take the provided cloud URL and call the "GetCurrentUserHandler" method. But we were only checking that it returned a successful response, not that it was actually valid JSON.
So in the "https://google.com" case, Google returned HTML describing a 404 error, but since the sever response was 200, the Pulumi CLI assumed things were on the up and up.
We now parse the response as JSON, and confirm the response has a `name` property that is non-nil. This heuristic covers the majority of false-positive cases, but without us needing to move all of the service's API shape for users, which includes organizations, which includes Clouds, etc. into `pulumi`.
Fixes https://github.com/pulumi/pulumi-service/issues/457. As an added bonus, we now return a much more useful error message.
In the Pulumi Cloud, there is no guarantee that two stacks will share
the same encryption key. This means that encrypted config can not be
shared across stacks (in the Pulumi.yaml) file. To mimic this behavior
in the local experience, we now use a unique key per stack.
When upgrading an existing project, for any stack with existing
secrets, we copy the existing key into this stack. Future stacks will
get thier own encryption key. This strikes a balance between
expediency of implementation, the end user UX and not having to make a
breaking change.
As part of this change, I have introduced a CHANGELOG.md file in the
root of the repository and added a small note about the change to it.
Fixes#769
We did not pretty print either the workspace settings file or the
repository settings file, but pretty print other files like the
credentials file and checkpoints. Now we do.
Fixes#540
This PR surfaces the configuration options available to updates, previews, and destroys to the Pulumi Service. As part of this I refactored the options to unify them into a single `engine.UpdateOptions`, since they were all overlapping to various degrees.
With this PR we are adding several new flags to commands, e.g. `--summary` was not available on `pulumi destroy`.
There are also a few minor breaking changes.
- `pulumi destroy --preview` is now `pulumi destroy --dry-run` (to match the actual name of the field).
- The default behavior for "--color" is now `Always`. Previously it was `Always` or `Never` based on the value of a `--debug` flag. (You can specify `--color always` or `--color never` to get the exact behavior.)
Fixes#515, and cleans up the code making some other features slightly easier to add.
In travis, we've seen cases where writes to our standard streams
results in an error like: `/dev/stderr: resource temporarily
unavailable` which causes the tests to panic.
Now, in a perfect world, writes to /dev/stderr would not fail in this
way, but we do not live in a perfect world. Other processes on the
machine may make stderr/stdout non-blocking. We've are now seeing this
failure in Travis more often and it is masking real Pulumi failures
we want to debug.
This change restructures the test framework code a bit, to make it
easier to introduce additional languages. Our knowledge of Yarn and
Node.js project structure, for instance, was previously baked in to
the test logic, in a way that was hard to make, for instance, Yarn
optional. (In Python, of course, it will not be used.) To better
support this, I've moved some state onto a new programTester struct
that we can use to lazily find binaries required during the testing
(such as Yarn, Pip, and so on). I'm committing this separately so
that I can minimize merge conflicts in the Python work.
Fix two references to the now-unnamed `dir` that should have been to
other variables.
Check a real condition before the deferred call to RemoveAll instead of
checking the error return.
My previous change to stop supplying unknown properties to providers
broke `pulumi preview` in the case of unknown inputs. This change
restores the previous behavior for previews only; the new unknown-free
behavior remains for applies.
Fixes#790.
Before these changes, we were inconsistent in our treatment of unknown
property values across the resource provider RPC interface. `Check` and
`Diff` were retaining unknown properties in inputs and outputs;
`Create`, `Update`, and `Delete` were not. This interacted badly with
recent changes to `Check` to return all provider inputs--i.e. not just
defaults--from that method: if an unknown input was provided, it would
be present in the returned inputs, which would eventually confuse the
differ by giving the appearance of changes where none were present.
These changes remove unknowns from the provider interface entirely:
unknown property values are never passed to a provider, and a provider
must never return an unknown property value.
This is the primary piece of the fix for pulumi/pulumi-terraform#93.
These changes refactor the engine's entrypoints--Deploy, Destroy, and
Preview--to be update-centric rather than stack-centric. Each of these
methods now takes a value of a new type, Update, that abstracts away the
vagaries of fetching and maintaining the update's state. This
refactoring also reinforces Pulumi.yaml as a CLI concept rather than an
engine concept; the CLI is now the only reader/writer of this format.
These changes will smooth the way for a few refactorings on the service
side that will aid in update isolation.
These changes add the ability to export a stack's latest deployment or
import a new deployment to a stack via the Pulumi CLI. These
capabilities are exposed by two new verbs under `stack`:
- export, which writes the current stack's latest deployment to stdout
- import, which reads a new deployment from stdin and applies it to the
current stack.
In the local case, this simply involves reading/writing the stack's
latest checkpoint file. In the cloud case, this involves hitting two new
endpoints on the service to perform the export or import.
This PR updates the `pkg/testing/integration` package to support running integration tests against the Pulumi Service if desired. This is done through adding new options to `ProgramTestOptions`. (Generally adding support for providing values to flags that were previously inaccessible.)
I added an integration test to confirm that it all works if the PULUMI_API environment variable is set. These tests aren't run in Travis, only manually. Since we cannot reliably run tests from `master` against the service because of the delay in rolling out updates to the Pulumi SDK, etc.
This change incorporates feedback on https://github.com/pulumi/pulumi/pull/764,
in addition to refactoring the retry logic to use our retry framework rather
than hand-rolling it in the REST API code. It's a minor improvement, but at
least lets us consolidate some of this logic which we'll undoubtedly use more
of over time.
We saw an issue where a user was mid-update, and got a networking
error stating `read: operation timed out`. We believe this was simply
a local client error, due to a flaky network. We should be resilient
to such things during updates, particularly when there's no way to
"reattach" to an in-progress udpate (see pulumi/pulumi#762).
This change accomplishes this by changing our retry logic in the
cloud backend's waitForUpdates function. Namely:
* We recognize three types of failure, and react differently:
- Expected HTTP errors. For instance, the 504 Gateway Timeouts
that we already retried in the face of. In these cases, we will
silently retry up to 10 times. After 10 times, we begin warning
the user just in case this is a persistent condition.
- Unexpected HTTP errors. The CLI will quit immediately and issue
an error to the user, in the usual ways. This covers
Unauthorized among other things. Over time, we may find that we
want to intentionally move some HTTP errors into the above.
- Anything else. This covers the transient networking errors case
that we have just seen. I'll admit, it's a wide net, but any
instance of this error issues a warning and it's up to the user
to ^C out of it. We also log the error so that we'll see it if
the user shares their logs with us.
* We implement backoff logic so that we retry very quickly (100ms)
on the first failure, and more slowly thereafter (1.5x, up to a max
of 5 seconds). This helps to avoid accidentally DoSing our service.
This merging causes similar issues to those it did in `Check`, and
differs from the approach we take to `Diff`. This can causes problems
such as an inability to remove properties.
Use the new {en,de}crypt endpoints in the Pulumi.com API to secure
secret config values. The ciphertext for a secret config value is bound
to the stack to which it applies and cannot be shared with other stacks
(e.g. by copy/pasting it around in Pulumi.yaml). All secrets will need
to be encrypted once per target stack.
This fixes a few more edit directory issues, where we didn't
correctly propagate the changes in edit directory required during
subsequent destroy/stack activities. It also fixes a few error
paths so that we preserve the right directory to be removed.
This change implements resource protection, as per pulumi/pulumi#689.
The overall idea is that a resource can be marked as "protect: true",
which will prevent deletion of that resource for any reason whatsoever
(straight deletion, replacement, etc). This is expressed in the
program. To "unprotect" a resource, one must perform an update setting
"protect: false", and then afterwards, they can delete the resource.
For example:
let res = new MyResource("precious", { .. }, { protect: true });
Afterwards, the resource will display in the CLI with a lock icon, and
any attempts to remove it will fail in the usual ways (in planning or,
worst case, during an actual update).
This was done by adding a new ResourceOptions bag parameter to the
base Resource types. This is unfortunately a breaking change, but now
is the right time to take this one. We had been adding new settings
one by one -- like parent and dependsOn -- and this new approach will
set us up to add any number of additional settings down the road,
without needing to worry about breaking anything ever again.
This is related to protected stacks, as described in
pulumi/pulumi-service#399. Most likely this will serve as a foundational
building block that enables the coarser grained policy management.
This change adds the ability to do very coarse-grained negative
tests in our integration test framework. Either a test itself,
or one of its edits, may be marked ExpectFailure == true, at which
point either the preview or update MUST fail (and, if one fails
without this being set, we still treat it as an error).
Our recent changes to colorization changed from a boolean to a tri-valued
enum (Always, Never, Raw). The events from the service, however, are still
boolean-valued. This changes the message payload to carry the full values.
The prior behavior with cloud authentication was a bit confusing
when authenticating against anything but https://pulumi.com/. This
change fixes a few aspects of this:
* Improve error messages to differentiate between "authentication
failed" and "you haven't logged into the target cloud URL."
* Default to the cloud you're currently authenticated with, rather
than unconditionally selecting https://pulumi.com/. This ensures
$ pulumi login -c https://api.moolumi.io
$ pulumi stack ls
works, versus what was currently required
$ pulumi login -c https://api.moolumi.io
$ pulumi stack ls -c https://api.moolumi.io
with confusing error messages if you forgot the second -c.
* To do this, our default cloud logic changes to
1) Prefer the explicit -c if supplied;
2) Otherwise, pick the "currently authenticated" cloud; this is
the last cloud to have been targeted with pulumi login, or
otherwise the single cloud in the list if there is only one;
3) https://pulumi.com/ otherwise.
We hadn't previously passed the planning flag when printing resource
outputs, meaning any computed ones now are being printed as "undefined".
Instead, we prefer to see the "computed<string>" type name.
We do not need all of the information in the old state for this call, as
outputs will not be read by the provider during validation or defaults
computation.
This change adds a bit more tracing context to RPC marshaling
logging so that it's easier to attribute certain marshaling calls.
Prior to this, we'd just have a flat list of "marshaled property X"
without any information about what the marshaling pertained to.
This change passes a resource's old output state, so that it contains
everything -- defaults included -- for purposes of the provider's diffing.
Not doing so can lead the provider into thinking some of the requisite
state is missing.
Part of the work to make it easier to tests of diff output. Specifically, we now allow users to pass --color=option for several pulumi commands. 'option' can be one of 'always', 'never', 'raw', and 'auto' (the default).
The meaning of these flags are:
1. auto: colorize normally, unless in --debug
2. always: always colorize no matter what
3. never: never colorize no matter what.
4. raw: colorize, but preserve the original "<{%%}>" style control codes and not the translated platform specific codes. This is for testing purposes and ensures we can have test for this stuff across platform.
This will allow us to remove a lot of current boilerplate in individual tests, and move it into the test harness.
Note that this will require updating users of the integration test framework. By moving to a property bag of inputs, we should avoid needing future breaking changes to this API though.
This change adds rudimentary delete-before-create support (see
pulumi/pulumi#450). This cannot possibly be complete until we also
implement pulumi/pulumi#624, becuase we may try to delete a resource
while it still has dependent resources (which almost certainly will
fail). But until then, we can use this to manually unwedge ourselves
for leaf-node resources that do not support old and new resources
living side-by-side.
As articulated in #714, the way config defaults to workspace-local
configuration is a bit error prone, especially now with the cloud
workflow being the default. This change implements several improvements:
* First, --save defaults to true, so that configuration changes will
persist into your project file. If you want the old local workspace
behavior, you can specify --save=false.
* Second, the order in which we applied configuration was a little
strange, because workspace settings overwrote project settings.
The order is changed now so that we take most specific over least
specific configuration. Per-stack is considered more specific
than global and project settings are considered more specific
than workspace.
* We now warn anytime workspace local configuration is used. This
is a developer scenario and can have subtle effects. It is simply
not safe to use in a team environment. In fact, I lost an arm
this morning due to workspace config... and that's why you always
issue warnings for unsafe things.
If the service returns a 504, we happily keep looping around and
retrying until we get a valid update. Unfortunately, we missed the
else condition, which is what happens when this isn't a 504, leading
us to swallow real errors (500 and the like). Trivial fix.
Fixespulumi/pulumi#712.
