We only have one AppVeyor worker and building topic branches causes us
to build large backups in our queues. This is made worse when folks
are iterating on a PR because each push queues not only a PR
build (which we want) but also the topic branch build (which we don't
care about so much).
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.
In Travis, Node sees that `stdout` is a pipe and sets it to nonblocking.
Go's standard library isn't prepared for `stdout` to be nonblocking, so
sometimes long print statements can fail.
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.
