Martin Atkins c57dbebe84 documentation: explain provider dev environment setup
The intent here is just to introduce some initial docs on our recommended
way to develop plugins in the same GOPATH as Terraform itself. The
documentation in this area needs some more fundamental rework as it is
rather outdated and mis-organized, but that's outside the scope of what
this change is trying to achieve.

James Bardin f10163ecc7 graph should not panic with no config
The backends replace a nil module tree with an empty one before building
the graph, so the graph command needs to do the same.

Martin Atkins ac250d2792 plugin/discovery: trim off .exe suffix when parsing filenames
On Windows systems the plugin binaries use a .exe suffix, which we were
misparsing as part of either the "v" or "x" parts of the filename.

This fixes #15578.

Martin Atkins 23f9c8785e command/e2etest: an initial test for the primary workflow
This e2etest runs an init, plan, apply, destroy sequence against a test
configuration using the real template and null providers downloaded from
the official repository.

This test _does_ trample a bit on the scope of some already-existing
tests, but this is mainly just to check our assumptions about how
Terraform behaves to ensure that we can reach our main conclusion here:
that the main Terraform workflow commands interact correctly with each
other in real use and we can complete the full workflow.

Martin Atkins 52df81ee49 command/e2etest: test that we can install provider plugins
We already have good tests for the business logic around provider
installation, but the existing tests all stub out the main repository
server. This test completes that coverage by verifying that the installer
is able to run against the real repository and install an official release
of the template provider.

Martin Atkins 0e0b0d125a command/e2etest: "terraform version" test
This basic test is here primarily because it's one of the few that can
run without reaching out to external services, and so it means our usual
test runs will catch situations where the main executable build is
somehow broken.

The version command itself is not very interesting to test, but it's
convenient in that its behavior is very predictable and self-contained.

Martin Atkins fee61a44b4 command/e2etest: end-to-end testing harness
Previously we had no automated testing of whether we can produce a
Terraform executable that actually works. Our various functional tests
have good coverage of specific Terraform features and whole operations,
but we lacked end-to-end testing of actual usage of the generated binary,
without any stubbing.

This package is intended as a vehicle for such end-to-end testing. When
run normally under "go test" it will produce a build of the main Terraform
binary and make it available for tests to execute. The harness exposes
a flag for whether tests are allowed to reach out to external network
services, controlled with our standard TF_ACC environment variable, so
that basic local tests can be safely run as part of "make test" while
more elaborate tests can be run easily when desired.

It also provides a separate mode of operation where the included script
make-archive.sh can be used to produce a self-contained test archive that
can be copied to another system to run the tests there. This is intended
to allow testing of cross-compiled binaries, by shipping them over to
the target OS and architecture to run without requiring a full Go compiler
installation on the target system.

The goal here is not to test again functionality that's already
well-covered by our existing tests, but rather to test chains of normal
operations against the build binary that are not otherwise tested
together.

James Bardin a1727ec4c2 Add warning to mismatched plan state
Forward-port the plan state check from the 0.9 series.
0.10 has improved the serial handling for the state, so this adds
relevant comments and some more test coverage for the case of an
incrementing serial during apply.

James Bardin 2b84e786e9 allow missing x-terraform-protocol-version
If the release site is missing the "x-terraform-protocol-version"
header, we should fetch the latest spec'ed release. Downloading the
wrong protocol version can't do any damage, and the version present is
more than likely compatible.

James Bardin 87b2c0cf8f Merge pull request #15556 from hashicorp/jbardin/backend-tests
backend state tests must honor lineage
2017-07-14 14:56:54 -04:00
James Bardin bcb11f6d89 have the consul client manage the lock session
When a consul lock is lost, there is a possibility that the associated
session is still active. Most commonly, the long request to watch the
lock key may error out, while the session is continually refreshed at a
rate of TTL/2.

First have the lock monitor retry the lock internally for at least 10
seconds (5 attempts with the default 2 second wait time). In most cases
this will reconnect on the first try, keeping the lock channel open.

If the consul lock can't recover itself, then cancel the session as soon
as possible (terminating the PreiodicRenew will call Session.Destroy),
and start over. In the worse case, the consul agents were split, and the
session still exists on the leader so we may need to wait for the old
session TTL, plus the LockWait time to renew the lock.

We use a Context for the cancellation channels here, because that
removes the need to worry about double-closes and nil channels. It
requires an awkward adapter goroutine for now to convert the Done()
`<-chan` to a `chan` for PeriodicRenew, but makes the rest of the code
safer in the long run.

James Bardin 193d4b868c backend state tests must honor lineage
Remote state implementations may initialize a lineage when creating a

lineage to write a new state to the backend.

James Nugent aa1e5e996a README: Add link to provider repos to "Developing" (#15546)
This commit adds a link to the GitHub organization which contains the
formerly-built-in providers, and modifies the `plugin-dev` target
documentation to use a provider which is unlikely to be moved out of the
core repository.

James Bardin 60ea42cd1c Add testProviderConfig to import tests
Provider import tests previously didn't have to supply a config, but
terraform now requires the provider to be declared for discovery.

testProviderConfig returns a stub config with provider blocks based
on the TestCase Providers. This allows basic import tests in providers
to remain unchanged.

James Bardin 8e2ee53ed3 Merge pull request #15501 from hashicorp/jbardin/race
Make sure shadow.closeWalker doesn't copy Mutexes
2017-07-07 12:39:46 -04:00
James Bardin 657932261b Make sure shadow.closeWalker doesn't copy Mutexes
The Close methods on shadow.Values require pointer receivers because
they contain a sync.Mutex, but that value was being copied through
Value.Interface by the closeWalker.  Because reflectwalk passes the
struct fields to the StructField method as they are defined in the
struct, and they may have been read as a value, we can't immediately
call Interface() to check the method set without possibly copying the
internal mutex values. Use the Implements method to first check if we
need to call Interface, and if it's not, then we can check if the value
is addressable.

Because of this use of reflection, we can't vet for the copying of these
locks. The minimal amount of code in the Close method left us only with
a race detected within the mutex itself, which leads to a stacktrace
pointing to the runtime rather than our code.

Martin Atkins 39c4d6ab1f Merge #15424: Improve robustness of state persistence handling
Previously the APIs for state persistence and management had some problematic cases where we depended on hidden mutations of the state structure as side-effects of otherwise-innocent-looking operations, which was a frequent cause of accidental regressions due to faulty assumptions.

This new model attempts to isolate certain state mutations to just within the state managers, and makes the state managers work on separated snapshots of the state rather than on the "live" object to reduce the risk of race conditions.

Martin Atkins fee1197cf9 command: terraform state rm to require at least one argument
Due to how the state filter machinery works, passing no arguments is valid
and matches _all_ resources.

It is very unlikely that someone wants to remove everything from state, so
this ends up being a very dangerous default for the "terraform state rm"
command, and surprising for someone who perhaps runs it looking for the
usage information.

So we'll be pragmatic here and reject the no-arguments case for this
command, accepting that it makes the unlikely case of intentionally
deleting all resources harder in order to make it less likely that it
will happen _unintentionally_.

If someone does really want to remove all resources from the state, they
can provide an explicit empty string argument, but this isn't documented
because it's a weird case that doesn't seem worth mentioning.

This fixes #15283.
