Most of the time an ssh authentication failure would be non-recoverable,
but some host images can start the ssh service before it is properly
configured, or before user authentication data is available.
Log ssh authentication errors and allow the provisioner to retry until
the connection timeout.
Added some more context to GetOkExists, moved Computed to NewValueKnown
to accommodate some changes that will be coming up in HCL2 that may make
"Computed" less intuitive of a function name, and updated the docs for
NewValueKnown as well.
This adds a new method to ResourceDiff: Computed, which exposes the
computed read result field to ResourceDiff. In the context of
customizing the diff, this is important as interpolated and otherwise
computed values will show up in the diff as blank, with no way of
determining if the value is actually blank or if it's a computed value
not available at diff customization time. Currently assumptions need to
be made on this, but this does not help in validation scenarios where
one needs to differentiate between an actual blank value and a value
that will be available later.
This is exposed for the most part via NewComputed in the diff, but the
tests cover both the config reader as well (with no diff, even though
this should not come up in normal operation) and also the newDiff reader
when someone sets a new value using SetNew and SetNewComputed.
This commit also exposes GetOkExists. The tests were mostly pulled from
ResourceData but a few were added to ensure that config was being
properly covered as well, in addition to covering SetNew and
SetNewComputed.
The indent function was stripping out newlines, causing multi-element
lists and maps to be rendered incorrectly.
We were also not quoting strings in these nested structures, leading to
weird behavior if any expression punctuation or newlines were present in
these strings.
This part of Terraform will get a more serious overhaul as part of
switching to the new parser/interpreter implementation but this is a
tactical fix to make the results of this command more usable in the
short term.
Rather than try to modify all the hundreds of calls to the temp helper
functions, and cleanup the temp files at every call site, have all tests
work within a single temp directory that is removed at the end of
TestMain.
In an earlier commit we added the "Best Practices" situation to try to
clarify the intended uses of named workspaces and to warn against using
them as an alternative to system decomposition.
However, the prior statement was cautious in its recommendations in the
interests of being pragmatic, and as a result we've seen that users have
in some cases misunderstood or disregarded these recommendations.
The new "When to use Multiple Workspaces" section aims to be more explicit
that having multiple separate Terraform configurations is the preferred
solution for many use-cases, and that workspaces are intended for a
more limited set of use-cases around convenient development and testing.
It also emphasizes the analogy to version control branches that was just
a footnote in the prior text, to help the reader become familiar with the
concept by relating it to a concept and workflow they are hopefully
already familiar with.
This new section also attempts to provide a more elaborate description of
the proposed alternative when the goal is system decomposition. In the
long run some of this content would probably be better placed elsewhere
since it is useful advice even for users who never discover named
workspaces, but it can live here for the time being to limit the scope of
this change until we are ready to make more comprehensive revisions to
the docs in this area.
Finally, the introductory documentation here is adjusted slightly in
preparation for the intended future expansion of workspaces to include
stored variable values and, for more tailored backends like Terraform
Enterprise, a full log of prior operations. More revisions will be
required to cover the specifics of this later, but this new framing will
hopefully help users form a mental model of named workspaces that has
room for these future enhancements and the corresponding concept in
Terraform Enterprise, rather than our previous framing that workspaces
are fundamentally just named states.
Fixed a bug in which an example custom provider would be saved as "terraform-provider-custom-v0.0.1" instead of "terraform-provider-custom_v0.0.1". Not an issue when running the bundle on TFE, but a problem when trying to run a terraform bundle locally.
Return the global default timeout if the ResourceData timeouts are nil.
Set the timeouts from the Resource when calling Resource.Data, so that
the config values are always available.
The state locking improvements for the regular command had the side
effect of locking the state in the console, import, graph and push
commands. Those commands had been updated to get a state via the
Backend.Context method, which locks the state whenever possible, and now
need to call Unlock directly.
Add Unlock calls to all commands that call Context directly.
Add a test to remote-exec to make sure the proper timeout is honored
during apply.
TODO: we need some test helpers for provisioners, so they can all be
verified.
The timeout for a provisioner is expected to only apply to the initial
connection. Keep the context for the communicator.Retry separate from
the global cancellation context.
