This change enables us to make progress on exposing data sources
(see pulumi/pulumi-terraform#29). The idea is to have an Invoke
function that simply takes a function token and arguments, performs
the function lookup and invocation, and then returns a return value.
This change adds first class support for capturing objects which are references to loaded Node modules.
If an object to be serialized is found as a loaded module which can be referenced as `require(<name>)`, then is is not serialized and is passed as a new kind of environment entry - `module` which will be de-serialized as a `require` statement.
Supports three cases:
1. built-in modules such as `http` and `path`
2. dependencies in the `node_modules` folder
3. other user-defined modules in the source folder
This allows natural use of `import`s with "inside" code. For example - note the use of `$` in the outside scope only on the "inside".
```typescript
import * as cloud from "@pulumi/cloud";
import * as $ from "cheerio";
let queue = new pulumi.Topic<string>("sites_to_process");
queue.subscribe("foreachurl", async (url) => {
let x = $("a", "<a href='foo'>hello</a>");
});
```
Also fixes free variable capture of `this` in arrow functions.
Fixes#342.
Defer build and publish logic into the makefiles instead of trying to
use Travis to do so. This let's us sidestep Travis's not great error
handling (see pulumi/home#21 for more details)
Print "modified" rather than "modifyd". This introduces a new method,
`resource.StepOp.PastTense()`, which returns the past tense description
of the operation.
The current `pulumi env` command just prints the deployment's info map
as-is, which leads to some ugly Go internal map printing output. Instead
of doing that, let's show a JSON-like map that is properly pretty printed.
This change improves our output formatting by generally adding
fewer prefixes. As shown in pulumi/pulumi#359, we were being
excessively verbose in many places, including prefixing every
console.out with "langhost[nodejs].stdout: ", displaying full
stack traces for simple errors like missing configuration, etc.
Overall, this change includes the following:
* Don't prefix stdout and stderr output from the program, other
than the standard "info:" prefix. I experimented with various
schemes here, but they all felt gratuitous. Simply emitting
the output seems fine, especially as it's closer to what would
happen if you just ran the program under node.
* Do NOT make writes to stderr fail the plan/deploy. Previously
we assumed that any console.errors, for instance, meant that
the overall program should fail. This simply isn't how stderr
is treated generally and meant you couldn't use certain
logging techniques and libraries, among other things.
* Do make sure that stderr writes in the program end up going to
stderr in the Pulumi CLI output, however, so that redirection
works as it should. This required a new Infoerr log level.
* Make a small fix to the planning logic so we don't attempt to
print the summary if an error occurs.
* Finally, add a new error type, RunError, that when thrown and
uncaught does not result in a full stack trace being printed.
Anyone can use this, however, we currently use it for config
errors so that we can terminate with a pretty error message,
rather than the monstrosity shown in pulumi/pulumi#359.
This includes a few changes:
* The repo name -- and hence the Go modules -- changes from pulumi-fabric to pulumi.
* The Node.js SDK package changes from @pulumi/pulumi-fabric to just pulumi.
* The CLI is renamed from lumi to pulumi.
While these codes can be understood on newer versions of Windows 10 (if
we were to set the console properties correctly) in general they do not
work and cause garbage to be printed to the screen. For now, just don't
colorize output on Windows.
There were two problems:
- node-gyp configure was failing because of different shell syntax
between windows and *nix.
- MSVC 2015 is not smart enough to understand our use of strlen actually
results in a constant value and prevents us from using it to create an
array, move to a macro based solution.
Instead of binding on 0.0.0.0 (which will listen on every interface)
let's only listen on localhost. On windows, this both makes the
connection Just Work and also prevents the Windows Firewall from
blocking the listen (and displaying UI saying it has blocked an
application and asking if the user should allow it)
This adds back Computed<T> as a short-hand for Promise<T | undefined>.
Subtly, all resource properties need to permit undefined flowing through
during planning Rather than forcing the long-hand version, which is easy
to forget, we'll keep the convention of preferring Computed<T>. It's
just a typedef and the runtime type is just a Promise.
As part of pulumi/pulumi-fabric#331, we've been exploring just using
undefined to indicate that a property value is absent during planning.
We also considered blocking the message loop to simplify the overall
programming model, so that all asynchrony is hidden.
It turns out ThereBeDragons 🐲 anytime you try to block the
message loop. So, we aren't quite sure about that bit.
But the part we are convicted about is that this Computed/Property
model is far too complex. Furthermore, it's very close to promises, and
yet frustratingly so far away. Indeed, the original thinking in
pulumi/pulumi-fabric#271 was simply to use promises, but we wanted to
encourage dataflow styles, rather than control flow. But we muddied up
our thinking by worrying about awaiting a promise that would never resolve.
It turns out we can achieve a middle ground: resolve planning promises to
undefined, so that they don't lead to hangs, but still use promises so
that asynchrony is explicit in the system. This also avoids blocking the
message loop. Who knows, this may actually be a fine final destination.
This provides a friendlier experience if the nodejs language service is
not on the path. Also, print a helpful message at the end of
`make configure` if PATH has not yet been setup.
This change flips the polarity on parallelism: rather than having a
--serialize flag, we will have a --parallel=P flag, and by default
we will shut off parallelism. We aren't benefiting from it at the
moment (until we implement pulumi/pulumi-fabric#106), and there are
more hidden dependencies in places like AWS Lambdas and Permissions
than I had realized. We may revisit the default, but this allows
us to bite off the messiness of dependsOn only when we benefit from
it. And in any case, the --parallel=P capability will be useful.
This change adds an optiona dependsOn parameter to Resource constructors,
to "force" a fake dependency between resources. We have an extremely strong
desire to resort to using this only in unusual cases -- and instead rely
on the natural dependency DAG based on properties -- but experience in other
resource provisioning frameworks tells us that we're likely to need this in
the general case. Indeed, we've already encountered the need in AWS's
API Gateway resources... and I suspect we'll run into more especially as we
tackle non-serverless resources like EC2 Instances, where "ambient"
dependencies are far more commonplace.
This also makes parallelism the default mode of operation, and we have a
new --serialize flag that can be used to suppress this default behavior.
Full disclosure: I expect this to become more Make-like, i.e. -j 8, where
you can specify the precise width of parallelism, when we tackle
pulumi/pulumi-fabric#106. I also think there's a good chance we will flip
the default, so that serial execution is the default, so that developers
who don't benefit from the parallelism don't need to worry about dependsOn
in awkward ways. This tends to be the way most tools (like Make) operate.
This fixespulumi/pulumi-fabric#335.
This change finishes the conversion of LUMIDL over to the new
runtime model, with the appropriate code generation changes.
It turns out the old model actually had a flaw in it anyway that we
simply didn't hit because we hadn't been stressing output properties
nearly as much as the new model does. This resulted in needing to
plumb the rejection (or allowance) of computed properties more
deeply into the resource property marshaling/unmarshaling logic.
As of these changes, I can run the GitHub provider again locally.
This change fixespulumi/pulumi-fabric#332.
