In an effort to improve performance and overall reliability, this PR moves the responsibility of uploading the Pulumi program from the Pulumi Service to the CLI. (Part of fixing https://github.com/pulumi/pulumi-service/issues/313.)
Previously the CLI would send (the dozens of MiB) program archive to the Service, which would then upload the data to S3. Now the CLI sends the data to S3 directly, avoiding the unnecessary copying of data around.
The Service-side API changes are in https://github.com/pulumi/pulumi-service/pull/323. I tested previews, updates, and destroys running the service and PPC on localhost.
The PR refactors how we handle the three kinds of program updates, and just unifies them into a single method. This makes the diff look crazy, but the code should be much simpler. I'm not sure what to do about supporting all the engine options for the Cloud-variants of Pulumi commands; I suspect that's something that should be handled at a later time.
We are now on our fourth vendoring tool: Govendor. This appears to
be about 10X faster than Dep, fails less frequently, and has a rich,
well documented set of commands (that make far more intuitive sense
to me, particularly when compared to Dep). I could never really get
Godep to work with vendor/ correctly, whereas Govendor did the trick
right away. Lastly, Terraform uses it, so we'll probably have fewer
headaches in that department also.
Adds a make task to generate code coverage for all Go sources.
That make task re-runs the tests, and can be fairly expensive,
so it is enabled only in the nightly tests for now.
Part of #206.
We were not propagating the error from `deployLatest` through
to the CLI error result. Despite out recent efforts to integrate
gometalinter, there were also several additional similar cases of
ignored error results reported by `errcheck`. Not yet clear why
these are not being reported via gometalinter.
Fixes#262.
In the old system, the core runtime/toolset understood that we are targeting
specific cloud providers at a very deep level. In fact, the whole code-generation
phase of the compiler was based on it.
In the new system, this difference is less of a "special" concern, and more of
a general one of mapping MuIL objects to resource providers, and letting *them*
gather up any configuration they need in a more general purpose way.
Therefore, most of this stuff can go. I've merged in a small amount of it to
the mu/x MuPackage, since that has to switch on cloud IaaS and CaaS providers in
order to decide what kind of resources to provision. For example, it has a
mu.x.Cluster stack type that itself provisions a lot of the barebone essential
resources, like a virtual private cloud and its associated networking components.
I suspect *some* knowledge of this will surface again as we implement more
runtime presence (discovery, etc). But for the time being, it's a distraction
getting the core model running. I've retained some of the old AWS code in the
new pkg/resource/providers/aws package, in case I want to reuse some of it when
implementing our first AWS resource providers. (Although we won't be using
CloudFormation, some of the name generation code might be useful.) So, the
ships aren't completely burned to the ground, but they are certainly on 🔥.
This adds a bunch of general scaffolding and the beginning of a `build` command.
The general engineering scaffolding includes:
* Glide for dependency management.
* A Makefile that runs govet and golint during builds.
* Google's Glog library for logging.
* Cobra for command line functionality.
The Mu-specific scaffolding includes some packages:
* mu/pkg/diag: A package for compiler-like diagnostics. It's fairly barebones
at the moment, however we can embellish this over time.
* mu/pkg/errors: A package containing Mu's predefined set of errors.
* mu/pkg/workspace: A package containing workspace-related convenience helpers.
in addition to a main entrypoint that simply wires up and invokes the CLI. From
there, the mu/cmd package takes over, with the Cobra-defined CLI commands.
Finally, the mu/pkg/compiler package actually implements the compiler behavior.
Or, it will. For now, it simply parses a JSON or YAML Mufile into the core
mu/pkg/api types, and prints out the result.
