On windows, we have to indirect through a batch file to launch plugins,
which means when we go to close a plugin, we only kill cmd.exe that is
running the batch file and not the underlying node process. This
prevents `pulumi` from exiting cleanly. So on Windows, we also kill any
direct children of the plugin process
Fixes#504
Now that config is stored in Pulumi.yaml, we need to mimic the behavior
around .pulumi/ while edits are applied. This will ensure that config
values carry forward from the original program settings.
This fixespulumi/pulumi-aws#48.
This improves a few things about assets:
* Compute and store hashes as input properties, so that changes on
disk are recognized and trigger updates (pulumi/pulumi#153).
* Issue explicit and prompt diagnostics when an asset is missing or
of an unexpected kind, rather than failing late (pulumi/pulumi#156).
* Permit raw directories to be passed as archives, in addition to
archive formats like tar, zip, etc. (pulumi/pulumi#240).
* Permit not only assets as elements of an archive's member list, but
also other archives themselves (pulumi/pulumi#280).
If --logtostderr is passed, and an unhandled error occurs that
was produced by the github.com/pkg/errors package, we will now
emit the stack trace. Much easier for debugging purposes.
Previously, the engine would write to io.Writer's to display output.
When hosted in `pulumi` these writers were tied to os.Stdout and
os.Stderr, but other applications hosting the engine could send them
other places (e.g. a log to be sent to an another application later).
While much better than just using the ambient streams, this was still
not the best. It would be ideal if the engine could just emit strongly
typed events and whatever is hosting the engine could care about
displaying them.
As a first step down that road, we move to a model where operations on
the engine now take a `chan engine.Event` and during the course of the
operation, events are written to this channel. It is the
responsibility of the caller of the method to read from the channel
until it is closed (singifying that the operation is complete).
The events we do emit are still intermingle presentation with data,
which is unfortunate, but can be improved over time. Most of the
events today are just colorized in the client and printed to stdout or
stderr without much thought.
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.
We are renaming Lumi to Pulumi Fabric. This change simply renames the
pulumi/lumi repo to pulumi/pulumi-fabric, without the CLI tools and other
changes that will follow soon afterwards.
This change introduces a --debug option to the plan, deploy, and
destroy commands. Unlike --logtostderr, which merely hooks into the
copious Glogging that we perform (and is therefore meant for developers
of the tools themselves and not end users), --debug hooks into the
user-facing debug stream. This now includes any debug messages coming
from the resource providers as they perform their tasks.
This change restructures a lot more pertaining to deployments, snapshots,
environments, and the like.
The most notable change is that the notion of a deploy.Source is introduced,
which splits the responsibility between the deploy.Plan -- which simply
understands how to compute and carry out deployment plans -- and the idea
of something that can produce new objects on-demand during deployment.
The primary such implementation is evalSource, which encapsulates an
interpreter and takes a package, args, and config map, and proceeds to run
the interpreter in a distinct goroutine. It synchronizes as needed to
poke and prod the interpreter along its path to create new resource objects.
There are two other sources, however. First, a nullSource, which simply
refuses to create new objects. This can be handy when writing isolated
tests but is also used to simulate the "empty" environment as necessary to
do a complete teardown of the target environment. Second, a fixedSource,
which takes a pre-computed array of objects, and hands those, in order, to
the planning engine; this is mostly useful as a testing technique.
Boatloads of code is now changed and updated in the various CLI commands.
This further chugs along towards pulumi/lumi#90. The end is in sight.
There are a few things that annoyed me about the way our CLI works with
directories when loading packages. For example, `lumi pack info some/pack/dir/`
never worked correctly. This is unfortunate when scripting commands.
This change fixes the workspace detection logic to handle these cases.
The change to flow logging to plugins is nice, however, it can be
annoying because all writes to stderr are interepreted on the Lumi
side as errors. After this change, we will only flow if
--logflow is passed, e.g. as in
$ lumi --logtostderr --logflow -v=9 deploy ...
This change flows --logtostderr and -v=x settings to any dynamically
loaded plugins so that running Lumi's command line with these flags
will also result in the plugins logging at the requested levels. I've
found this handy for debugging purposes.
This change revives some compiler tests that are still lingering around
from the old architecture, before our latest round of ship burning.
It also fixes up some bugs uncovered during this:
* Don't claim that a symbol's kind is incorrect in the binder error
message when it wasn't found. Instead, say that it was missing.
* Do not attempt to compile if an error was issued during workspace
resolution and/or loading of the Mufile. This leads to trying to
load an empty path and badness quickly ensues (crash).
* Issue an error if the Mufile wasn't found (this got lost apparently).
* Rename the ErrorMissingPackageName message to ErrorInvalidPackageName,
since missing names are now caught by our new fancy decoder that
understands required versus optional fields. We still need to guard
against illegal characters in the name, including the empty string "".
* During decoding, reject !src.IsValid elements. This represents the
zero value and should be treated equivalently to a missing field.
* Do not permit empty strings "" as Names or QNames. The old logic
accidentally permitted them because regexp.FindString("") == "", no
matter the regex!
* Move the TestDiagSink abstraction to a new pkg/util/testutil package,
allowing us to share this common code across multiple package tests.
* Fix up a few messages that needed tidying or to use Infof vs. Info.
The binder tests -- deleted in this -- are about to come back, however,
I am splitting up the changes, since this represents a passing fixed point.
