Only open a new file descriptor for RefreshState if we haven't written a
state, and don't have the correct state open already. This prevents
windows from failing to refresh a locked state.
ReadState would hide any errors, assuming that it was an empty state.
This can mask errors on Windows, where the OS enforces read locks on the
state file.
Refreshing a locked state on windows could return nil if the read path
was locked, no state was yet written, and the read path is the same as
the write path.
Add a test that locks then refreshes a newly initialized state struct.
To make it easier to include third-party plugins in generated bundles, we'll now search a local directory for available plugins and skip attempting to install from releases.hashicorp.com if a dependency can be satisfied locally.
Combine the ExitStatus and Err values from remote.Cmd into an error
returned by Wait, better matching the behavior of the os/exec package.
Non-zero exit codes are returned from Wait as a remote.ExitError.
Communicator related errors are returned directly.
Clean up all the error handling in the provisioners using a
communicator. Also remove the extra copyOutput synchronization that was
copied from package to package.
The provisionerFail_createBeforeDestroy test was verifying the incorrect
output. The create_before_destroy instance in the state has an ID of
"bar" with require_new="abc", and a new instance would get an ID of
"foo" with require_new="xyz". The existing test was expecting the
following state:
aws_instance.bar: (1 deposed)
ID = bar
provider = provider.aws
require_new = abc
Deposed ID 1 = foo (tainted)
Which showed "bar" still the primary instance in the state, with the new
instance "foo" as being the deposed instance, though properly tainted.
The new output is:
aws_instance.bar: (tainted) (1 deposed)
ID = foo
provider = provider.aws
require_new = xyz
type = aws_instance
Deposed ID 1 = bar
Showing the new "foo instance as being the primary instance in the
state, with "bar" as the deposed instance.
Use the new ExitStatus method, and also check the cmd.Err() method for
errors.
Remove leaks from the output goroutines in both provisioners by
deferring their cleanup, and returning early on all error conditions.
This was updated to see if we can get at any error status from the
remote command and transport, which still is not available, but kept the
latest version since it fixes a couple race conditions.
The timeout for the remote command was taken from the wrong config
field, and the connection timeout was being used which is 5 min. Any
remote command taking more than 5 min would be terminated by
disconnecting the communicator. Remove the timeout from the context, and
rely on the global timeout provided by terraform.
There was no way to get the error from the communicator previously, so
the broken connection was silently ignored and the provisioner returned
successfully. Now we can use the new cmd.Err() method to retrieve any
errors encountered during execution.
The remote.Cmd struct could not convey any transport related error to
the caller, meaning that interrupted commands would show that they
succeeded.
Change Cmd.SetExited to accept an exit status, as well as an error to
store for the caller. Make the status and error fields internal,
require serialized access through the getter methods.
Users of remote.Cmd should not check both Cmd.Err() and Cmd.ExitStatus()
until after Wait returns.
Require communicators to call Cmd.Init before executing the command.
This will indicate incorrect usage of the remote.Cmd by causing a panic
in SetExitStatus.
For historical reasons, the handling of element types for maps is inconsistent with other collection types.
Here we begin a multi-step process to make it consistent, starting by supporting both the "consistent" form of using a schema.Schema and an existing erroneous form of using a schema.Type directly. In subsequent commits we will phase out the erroneous form and require the schema.Schema approach, the same as we do for TypeList and TypeSet.
Fixes: #17314
We now deal correctly with the creation of the state file - we were
not dealing well with a ResourceNotFound error
Now that this has been changed around, we try and create the statefile
and if there is an error, we look for an existing statefile - previously
this was not the order of operations
