Martin Atkins a42ebe389c Revert "have StateHook periodically PersistState"
This reverts commit b73d037761.

This commit seems to have introduced a race condition where we can
concurrently keep updating state after we've checked if we need to
increase the serial, and thus end up writing partial changes
to the state backend.

In the case of Terraform Enterprise, this fails altogether because
of the state hash consistency check it does.

James Bardin 6b700ff1fb replace lock_table with dynamodb_table in s3 cfg
Since the DynamoDB table used by the S3 backend is no longer only used
for locks, rename it in the config to remove any confusion about it
being lock-specific.

James Bardin 3df48bfc27 relock consul when lock is lost
Consul locks are based on liveness, and may be lost due timeouts,
network issued, etc. If the client determines the lock was lost, attempt
to reacquire the lock immediately.

The client was also not using the `lock` config option. Disable locks if
that is not set.

James Bardin e7502454b4 check for nil state in s3 client Get
The S3 client can return (nil, nil) when the remote state doesn't exist.
The caused a nil pointer dereference when checking the payload.MD5
against the expected value.

This can happen if the remote state was manually removed, but the digest
entry was left in the DynamoDB table.

James Bardin 9e4c0ff2ad call PersistState immediately when cancelling
When the backend operation is cancelled, immediately call PersistState.
The is a high likelihood that the user is going to terminate the process
early if the provider doesn't return in a timely manner, so persist as
much state as possible.

James Bardin b73d037761 have StateHook periodically PersistState
Have StateHook periodically call PersistState to flush any cached state
to permanent storage. This uses a minimal 10 second interval between
calls to PersistState.

2017-05-24 13:51:33 -04:00
James Bardin 0022d224e8 store and verify s3 remote state checksum
Updates to objects in S3 are only eventually consistent. If the
RemoteClient has a DynamoDB table available, use that to store a
checksum of the last written state, so the object can be verified by the
next client to call Get.

Terraform currently doesn't have any sort of user feedback around
RefreshState/Get, so we poll only for a short time before returning an
error.

Martin Atkins 9cda37205d backend/local: create local state file if backend write fails
In the old remote state system we had the idea of a local backup, which
is actually still present for the legacy backends but no longer applies
for the new-style backends like the s3 backend.

It's problematic when an apply runs for long enough that someone's
time-limited AWS STS credentials expire and then Terraform fails and can't
persist state to S3.

To reduce the risk of lost state, here we add some extra fallback code
for the local apply operation in particular. If either state writing
or state persisting fail then we attempt to write the state to a special
backup file errored.tfstate, and produce an error message that guides the
user on how to retry uploading this state.

In the unlikely event that we can't write to local disk either (e.g.
permissions problems) we take a last-ditch attempt to dump the JSON onto
stdout and advise the user to manually copy it into a file for import.
If even that doesn't work for some reason, we assume a critical Terraform
bug (JSON-serialization problem with states?) and bail out with an
apologetic error message.

This is implemented for the apply command in particular because this is
the one command where new objects are created in real APIs that we don't
want to lose track of. For other operations it's less bad to just generate
a simple error message and have the user retry.

This fixes #14298.

James Bardin b279b1abb5 check for named s3 states before acquiring a lock
In order to force-unlock a named state, we have to fetch that state
first. Don't attempt to acquire a lock if we know the state already
exists in s3.
2017-05-19 14:40:59 -04:00
James Bardin a2d452acec failing test to force-unlock a named state in s3
The State call attempts to get a lock before determining if a named
state exists. This prevents force-unlock, since we need the state to
call Unlock.

James Bardin 928e60672f context Refresh and Apply sometimes return nil
The documentation for Refresh indicates that it will always return a
valid state, but that wasn't true in the case of a graph builder error.
While this same concept wasn't documented for Apply, it was still
assumed in the terraform apply code.

Since the helper testing framework relies on the absence of a state to
determine if it can call Destroy, the Context can't can't start
returning a state in all cases. Document this, and use the State method
to fetch the correct state value after Apply.

Add a nil check to the WriteState function, so that writing a nil state
is a noop.

Make sure to init before sorting the state, to make sure we're not
attempting to sort nil values. This isn't technically needed with the
current code, but it's just safer in general.

James Bardin 5621d97925 cleanup consul lock entries
This matches the consul cli behavior, where locks are cleaned up after
use.

Return an error from re-locking the state. This isn't required by the
Locker interface, but it's an added sanity check for state operations.
What was incorrect here was returning an empty ID and error, which would
indicate that Lock/Unlock isn't supported.

James Bardin fa4dc01cf4 add named state support to the s3 backend
This adds named state (environment) support to the S3 backend.

A state NAME will prepend the configured s3 key with `env:/NAME/`.
The default state will remain rooted in the bucket for backwards
compatibility.

Locks in DynamoDB use the S3 key as the as the primary key value, so
locking will work as expected for multiple states.

"environments".

command: remove legacy remote state on migration
Fixes #12871

We were forgetting to remove the legacy remote state from the actual
state value when migrating. This only causes an issue when saving a plan
since the plan contains the state itself and causes an error where both
a backend + legacy state exist.

If saved plans aren't used this causes no noticable issue.

Due to buggy upgrades already existing in the wild, I also added code to
clear the remote section if it exists in a standard unchanged backend

backend/local: allow refresh on empty/non-existent state
This allows a refresh on a non-existent or empty state file. We changed
this in 0.9.0 to error which seemed reasonable but it turns out this
complicates automation that runs refresh since it now needed to
determine if the state file was empty before running.

Its easier to just revert this into a warning with exit code zero.

The reason this changed is because in 0.8.x and earlier, the output
would be simply empty with exit code zero which seemed odd.
