Adds `pulumi update` so you can deploy to the Pulumi Console (via PPC on the backend).
As per an earlier discussion (now lost because I rebased/squashed the commits), we want to be more deliberate about how to bifurcate "local" and "cloud" versions of every Pulumi command.
We can block this PR until we do the refactoring to have `pulumi` commands go through a generic "PulumiCloud" interface. But it would be nice to commit this so I can do more refining of the `pulumi` -> Console -> PPC workflow.
Another known area that will need to be revisited is how we render the PPC events on the CLI. Update events from the PPC are generated in a different format than the `engine.Event`, and we'll probably want to change the PPC to emit messages in the same format. (e.g. how we handle coloring, etc.)
The old contract library tried to be glog-friendly in its failfast behavior.
It turns out glog seldom does the right thing when goroutines are involved
(which, as of last sprint, they now are). We already had issues with stacks
not getting printed when --logtostderr was turned on, and the code tried
to work around this; but this still didn't work for the goroutines case.
All of this seems like way too much cleverness. Let's just use Go panics.
This change fixes a few things:
* Most importantly, we need to place a leading "." in the paths
to Gometalinter, otherwise some sub-linters just silently skip
the directory altogether. errcheck is one such linter, which
is a very important one!
* Use an explicit Gometalinter.json file to configure the various
settings. This flips on a few additional linters that aren't
on by default (line line length checking). Sadly, a few that
I'd like to enable take waaaay too much time, so in the future
we may consider a nightly job (this includes code similarity,
unused parameters, unused functions, and others that generally
require global analysis).
* Now that we're running more, however, linting takes a while!
The core Lumi project now takes 26 seconds to lint on my laptop.
That's not terrible, but it's long enough that we don't want to
do the silly "run them twice" thing our Makefiles were previously
doing. Instead, we shall deploy some $$($${PIPESTATUS[1]}-1))-fu
to rely on the fact that grep returns 1 on "zero lines".
* Finally, fix the many issues that this turned up.
I think(?) we are done, except, of course, for needing to drive
down some of the cyclomatic complexity issues (which I'm possibly
going to punt on; see pulumi/lumi#259 for more details).
After 233c5a8 landed, I noticed there are a few things to be fixed up:
* Run gometalinter in all the right places. We need to run both in
lint and lint_quiet targets. I've also cleaned up some of the logic
around what to suppress so there's less repetition.
* We currently @ meaningful commands, which is unfortunate, since it
makes debugging Makefiles tough (especially when looking at CI build
logs). Going forward, we should only use @ for meaningless commands,
like @echo.
* The AWS project wasn't actually running tslint, because it needs to
say `tslint './pack/**/*.ts' --exclude='./pack/node_modules/**'`.
The current script of `tslint lib/aws/pack/...` wasn't actually
running lint, hence we missed a lot of AWS lint issues.
* Fix up the issues that these fixes uncovered. Mostly err shadowing.
Glog doesn't actually print out the stack traces for all goroutines,
when --logtostderr is enabled, the same way it normally does. This
makes debugging more complex in some cases. So, we'll manually do it.
This is the first change of many to merge the MuPack/MuIL formats
into the heart of the "compiler".
In fact, the entire meaning of the compiler has changed, from
something that took metadata and produced CloudFormation, into
something that takes MuPack/MuIL as input, and produces a MuGL
graph as output. Although this process is distinctly different,
there are several aspects we can reuse, like workspace management,
dependency resolution, and some amount of name binding and symbol
resolution, just as a few examples.
An overview of the compilation process is available as a comment
inside of the compiler.Compile function, although it is currently
unimplemented.
The relationship between Workspace and Compiler has been semi-
inverted, such that all Compiler instances require a Workspace
object. This is more natural anyway and moves some of the detection
logic "outside" of the Compiler. Similarly, Options has moved to
a top-level package, so that Workspace and Compiler may share
access to it without causing package import cycles.
Finally, all that templating crap is gone. This alone is cause
for mass celebration!
This change just moves the assertion/failure functions from the pkg/util
package to pkg/util/contract, so things read a bit nicer (i.e.,
`contract.Assert(x)` versus `util.Assert(x)`).
