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.

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.

We did not pretty print either the workspace settings file or the
repository settings file, but pretty print other files like the

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.
Rather than displaying `computed` as we do during previews, display
`undefined` instead, as these values may be intentionally undefined by
the user's program.
Fixes#633.
Previously, we would compute all the output from the preview operation
and then display it as a single event. Instead, we should do this how
we handle things during deploy. Each logical print operaton gets a
single event and we stream them back over a channel during planning.
Fixes#660
This change just flows the project's "main" directory all the way
through to the plugins, fixing #667. In that work item, we discussed
alternative approaches, such as rewriting the asset paths, but this
is tricky because it's very tough to do without those absolute paths
somehow ending up in the checkpoint files. Just launching the
processes with the right pwd is far easier and safer, and it turns
out that, conveniently, we set up the plugin context in exactly the
same place that we read the project information.
If the stack config specifies AWS credentials, these should be used in the operations provider instead of ambient credentials. This is necessary to ensure that we have access to resources in the target account.
Fixespulumi/pulumi-service#389
* Take an options pointer so values can change as a test runs.
* Don't pass redundant information.
* Extract initialization routine.
* Fix caller.
* Check return value.
* Extract destruction logic.
* Move preview and update into their own function.
* Inline null check.
This change adds a `pulumi stack output` command. When passed no
arguments, it prints all stack output properties, in exactly the
same format as `pulumi stack` does (just without all the other stuff).
More importantly, if you pass a specific output property, a la
`pulumi stack output clusterARN`, just that property will be printed,
in a scriptable-friendly manner. This will help us automate wiring
multiple layers of stacks together during deployments.
This fixespulumi/pulumi#659.
* Revert "Make sure we properly update dir so that pulumi-destroy works."
This reverts commit 56bfc57998.
* Revert "Edits needs to continuously pass along the new directory. (#668)"
This reverts commit 8bd1822722.
* Revert "Refactor test code to make it simpler to validate code in the middle. (#662)"
This reverts commit ed65360157.
If a cloud you've previously authenticated with goes away -- as ours
sort of did, because the cloud endpoing in the CLI changed (to actually
be correct) -- then you can't logout without manually editing the
credentials file in your workspace. This is a little annoying. So,
rather than that, let's have a `pulumi logout --all` command that just
logs out of all clouds you are presently authenticated with.
This changes two things:
1) Always show the root stack, even when unchanged. This ensures
that you see the outputs during any updates, etc., which is nice.
2) Always show all outputs after operations. Before, we did some
diffing between old/new, which actually doesn't make much sense.
- Fix#644 "Re-enable use of local dev stacks". Rather than trying to be smart about using "pulumi.com" and inferring "api.pulumi.com", we just use whatever cloud URL the user provides. (e.g. "http://localhost:8080") We can improve the user experience later by providing friendly names for these things upon login. So we can show "Pulumi" or "Contoso" instead of the URL -- but let's cross that bridge later.
- Fix#640, "Better error on `pulumi login`". We only provide the more friendly error about needing to login IFF you are trying to use an authenticated Pulumi API without having creds.
The two-phase output properties change broke the ability to recover
from a failed replacement that yields pending deletes in the checkpoint.
The issue here is simply that we should remember pending registrations
only for logical operations that *also* have a "new" state (create or
update). This commit fixes this, and also adds a new step test with
fault injection to probe many interesting combinations of steps.
If the process we are trying to kill has already exited, don't treat
this as an error. This can happen when we snapshot the process tree
before the process exits but it has exited by the time we get to
trying to kill it.
Fixes#654
Every single resource has a type prefix of
pulumi:pulumi:Stack$
which makes URNs quite lengthy without adding any value. Since
they all have this prefix, adding it doesn't help to disambiguate.
This change skips adding the parent URN part when it is the built-in
automatic stack type name.
At some point, we fixed a bug in the way state is managed for "same"
steps, which meant that we wouldn't see newly added output properties.
This had the effect that, if you had a stack already stood up, and
updated it to have output properties, we would miss them. (Stacks
stood up from scratch would still have them.) This fixes that problem,
in addition to two other things: 1) we need to sort output property
names to ensure a deterministic ordering, and 2) we need to also
unconditionally apply the outputs RPC coming in, to ensure that the
resulting resource always has the correct outputs (so that for example
deleting prior output properties actually deletes them).
Also add some testing for this area to make sure we don't break again.
Fixespulumi/pulumi#631.
These changes push the `config.{Map,Value}` interfaces further down into
the deployment engine so that configuration can be decrypted nearer to
its use.
This is the first part of the fix for pulumi/pulumi-ppc#112.
As documented in issue #616, the inputs/defaults/outputs model we have
today has fundamental problems. The crux of the issue is that our
current design requires that defaults present in the old state of a
resource are applied to the new inputs for that resource.
Unfortunately, it is not possible for the engine to decide which
defaults remain applicable and which do not; only the provider has that
knowledge.
These changes take a more tactical approach to resolving this issue than
that originally proposed in #616 that avoids breaking compatibility with
existing checkpoints. Rather than treating the Pulumi inputs as the
provider input properties for a resource, these inputs are first
translated by `Check`. In order to accommodate provider defaults that
were chosen for the old resource but should not change for the new,
`Check` now takes the old provider inputs as well as the new Pulumi
inputs. Rather than the Pulumi inputs and provider defaults, the
provider inputs returned by `Check` are recorded in the checkpoint file.
Put simply, these changes remove defaults as a first-class concept
(except inasmuch as is required to retain the ability to read old
checkpoint files) and move the responsibilty for manging and
merging defaults into the provider that supplies them.
Fixes#616.
This change implements some feedback from @ellismg.
* Make backend.Stack an interface and let backends implement it,
enabling dynamic type testing/casting to access information
specific to that backend. For instance, the cloud.Stack conveys
the cloud URL, org name, and PPC name, for each stack.
* Similarly expose specialized backend.Backend interfaces,
local.Backend and cloud.Backend, to convey specific information.
* Redo a bunch of the commands in terms of these.
* Keeping with this theme, turn the CreateStack options into an
opaque interface{}, and let the specific backends expose their
own structures with their own settings (like PPC name in cloud).
* Show both the org and PPC names in the cloud column printed in
the stack ls command, in addition to the Pulumi Cloud URL.
Unrelated, but useful:
* Special case the 401 HTTP response and make a friendly error,
to tell the developer they must use `pulumi login`. This is
better than tossing raw "401: Unauthorized" errors in their face.
* Change the "Updating stack '..' in the Pulumi Cloud" message to
use the correct action verb ("Previewing", "Destroying", etc).
This change does two things:
1) Adds progress reporting to our uploads.
2) Eliminate the sleeps that burned 7 seconds at the front of
any cloud update, needlessly. It's actually impressively
fast without these!
This improves the overall cloud CLI experience workflow.
Now whether a stack is local or cloud is inherent to the stack
itself. If you interact with a cloud stack, we transparently talk
to the cloud; if you interact with a local stack, we just do the
right thing, and perform all operations locally. Aside from sometimes
seeing a cloud emoji pop-up ☁️, the experience is quite similar.
For example, to initialize a new cloud stack, simply:
$ pulumi login
Logging into Pulumi Cloud: https://pulumi.com/
Enter Pulumi access token: <enter your token>
$ pulumi stack init my-cloud-stack
Note that you may log into a specific cloud if you'd like. For
now, this is just for our own testing purposes, but someday when we
support custom clouds (e.g., Enterprise), you can just say:
$ pulumi login --cloud-url https://corp.acme.my-ppc.net:9873
The cloud is now the default. If you instead prefer a "fire and
forget" style of stack, you can skip the login and pass `--local`:
$ pulumi stack init my-faf-stack --local
If you are logged in and run `pulumi`, we tell you as much:
$ pulumi
Usage:
pulumi [command]
// as before...
Currently logged into the Pulumi Cloud ☁️https://pulumi.com/
And if you list your stacks, we tell you which one is local or not:
$ pulumi stack ls
NAME LAST UPDATE RESOURCE COUNT CLOUD URL
my-cloud-stack 2017-12-01 ... 3 https://pulumi.com/
my-faf-stack n/a 0 n/a
And `pulumi stack` by itself prints information like your cloud org,
PPC name, and so on, in addition to the usuals.
I shall write up more details and make sure to document these changes.
This change also fairly significantly refactors the layout of cloud
versus local logic, so that the cmd/ package is resonsible for CLI
things, and the new pkg/backend/ package is responsible for the
backends. The following is the overall resulting package architecture:
* The backend.Backend interface can be implemented to substitute
a new backend. This has operations to get and list stacks,
perform updates, and so on.
* The backend.Stack struct is a wrapper around a stack that has
or is being manipulated by a Backend. It resembles our existing
Stack notions in the engine, but carries additional metadata
about its source. Notably, it offers functions that allow
operations like updating and deleting on the Backend from which
it came.
* There is very little else in the pkg/backend/ package.
* A new package, pkg/backend/local/, encapsulates all local state
management for "fire and forget" scenarios. It simply implements
the above logic and contains anything specific to the local
experience.
* A peer package, pkg/backend/cloud/, encapsulates all logic
required for the cloud experience. This includes its subpackage
apitype/ which contains JSON schema descriptions required for
REST calls against the cloud backend. It also contains handy
functions to list which clouds we have authenticated with.
* A subpackage here, pkg/backend/state/, is not a provider at all.
Instead, it contains all of the state management functions that
are currently shared between local and cloud backends. This
includes configuration logic -- including encryption -- as well
as logic pertaining to which stacks are known to the workspace.
This addresses pulumi/pulumi#629 and pulumi/pulumi#494.
This change adds a new manifest section to the checkpoint files.
The existing time moves into it, and we add to it the version of
the Pulumi CLI that created it, along with the names, types, and
versions of all plugins used to generate the file. There is a
magic cookie that we also use during verification.
This is to help keep us sane when debugging problems "in the wild,"
and I'm sure we will add more to it over time (checksum, etc).
For example, after an up, you can now see this in `pulumi stack`:
```
Current stack is demo:
Last updated at 2017-12-01 13:48:49.815740523 -0800 PST
Pulumi version v0.8.3-79-g1ab99ad
Plugin pulumi-provider-aws [resource] version v0.8.3-22-g4363e77
Plugin pulumi-langhost-nodejs [language] version v0.8.3-79-g77bb6b6
Checkpoint file is /Users/joeduffy/dev/code/src/github.com/pulumi/pulumi-aws/.pulumi/stacks/webserver/demo.json
```
This addresses pulumi/pulumi#628.
This change introduces automatic integrity checking for snapshots.
Hopefully this will help us track down what's going on in
pulumi/pulumi#613. Eventually we probably want to make this opt-in,
or disable it entirely other than for internal Pulumi debugging, but
until we add more complete DAG verification, it's relatively cheap
and is worthwhile to leave on for now.
This PR just wires the `Package.Main` field to the Pulumi Service (and in subsequent PRs, the `pulumi-service` and `pulumi-ppc` repos).
@joeduffy , should we just upload the entire `package.Package` type with the `UpdateProgramRequest` type? I'm not sure we want to treat that type as part of part of our public API surface area. But on the other hand, we'll need to mirror relevant fields in N places if we don't.
This change adds prefix +/- change markers for added and deleted
lines, in addition to the existing colorization. It also elides
empty strings from the diff which, due to our newline splitting,
always ended up with extra whitespace in the +/- output.
Previously, we were inconsistent on how we handled argument validation
in the CLI. Many commands used cobra.Command's Args property to
provide a validator if they took arguments, but commands which did not
rarely used cobra.NoArgs to indicate this.
This change does two things:
1. Introduce `cmdutil.ArgsFunc` which works like `cmdutil.RunFunc`, it
wraps an existing cobra type and lets us control the behavior when an
arguments validator fails.
2. Ensure every command sets the Args property with an instance of
cmdutil.ArgsFunc. The cmdutil package defines wrapers for all the
cobra validators we are using, to prevent us from having to spell out
`cmduitl.ArgsFunc(...)` everywhere.
Fixes#588
The prior change was incorrectly handling snapshotting of replacement
operations. Further, in hindsight, the older model of having steps
manage their interaction with the snapshot marking was clearer, so
I've essentially brought that back, merging it with the other changes.
This change simplifies the necessary RPC changes for components.
Instead of a Begin/End pair, which complicates the whole system
because now we have the opportunity of a missing End call, we will
simply let RPCs come in that append outputs to existing states.
We need to invoke the post-step event hook *after* updating the
state snapshots, so that it will write out the updated state.
We also need to re-serialize the snapshot again after we receive
updated output properties, otherwise they could be missing if this
happens to be the last resource (e.g., as in Stacks).
This change brings back component outputs to the overall system again.
In doing so, it generally overhauls the way we do resource RPCs a bit:
* Instead of RegisterResource and CompleteResource, we call these
BeginRegisterResource and EndRegisterResource, which begins to model
these as effectively "asynchronous" resource requests. This should also
help with parallelism (https://github.com/pulumi/pulumi/issues/106).
* Flip the CLI/engine a little on its head. Rather than it driving the
planning and deployment process, we move more to a model where it
simply observes it. This is done by implementing an event handler
interface with three events: OnResourceStepPre, OnResourceStepPost,
and OnResourceComplete. The first two are invoked immediately before
and after any step operation, and the latter is invoked whenever a
EndRegisterResource comes in. The reason for the asymmetry here is
that the checkpointing logic in the deployment engine is largely
untouched (intentionally, as this is a sensitive part of the system),
and so the "begin"/"end" nature doesn't flow through faithfully.
* Also make the engine more event-oriented in its terminology and the
way it handles the incoming BeginRegisterResource and
EndRegisterResource events from the language host. This is the first
step down a long road of incrementally refactoring the engine to work
this way, a necessary prerequisite for parallelism.
This changes our resource creation logic to tolerate missing children.
This ultimately shouldn't be necessary, but we appear to have a bug where
sometimes during deletions we end up with dangling child pointers. See
pulumi/pulumi#613; it tracks fixing the bug, and also removing this
workaround and reenabling the assertion.
When merging inputs and defaults in order to construct the set of inputs
for a call to `Create`, we must recursively merge each property value:
the provided defaults may contain nested values that must be present in
the merged result.
This change includes a NewResourceMap API, alongside the existing,
but renamed, NewResourceTree API. This also tidies up the resulting
struct for public consumption. This is required for downstream tests.
