These pages are thoroughly obsolete. Later, we'll delete and redirect them; for
now, we'll make sure the relevant pages are front-and-center in the sidebar if
someone somehow ends up on here.
Guides was already mostly gone. The two major remaining bits (the "core
workflow" guide and the "recommended practices" guide, which deserves a rename)
make much more sense as highly technical marketing material, and thus have a
natural home in the intro section.
Several `terraform` subcommands include sub-sub-commands; with our old sidebar
system, viewing those took you to an isolated "island" nav sidebar, away from
the main docs. The new navigation will adopt all these pages, so we don't need
to exile the reader to odd places.
As of this commit, that layout doesn't exist yet, but I'm isolating the one-line
changes to their own commit to try and keep your eyes from glazing over.
An earlier commit made this remove duplicates, which set the precedent
that this function is trying to canonically represent the _meaning_ of
the version constraints rather than exactly how they were expressed in
the configuration.
Continuing in that vein, now we'll also apply a consistent (though perhaps
often rather arbitrary) ordering to the terms, so that it doesn't change
due to irrelevant details like declarations being written in a different
order in the configuration.
The ordering here is intended to be reasonably intuitive for simple cases,
but constraint strings with many different constraints are hard to
interpret no matter how we order them so the main goal is consistency,
so those watching how the constraints change over time (e.g. in logs of
Terraform output, or in the dependency log file) will see fewer noisy
changes that don't actually mean anything.
We typically try to avoid making subjective, boasty claims in our
documentation in recent times, but there remained both some older
documentation that we've not recently revised and also some newer examples
that are, in retrospect, also perhaps more "boasty" than they need to be.
We prefer not to use this sort of boasty language because not everyone
using Terraform has the same background and experience, and so what is
"easy" or "intuitive" to one person may not be so to another person, and
that should not suggest that the second person is in any way wrong or
inadequate.
In reviewing some of our use of the word "easy" here I tried as much as
possible to surgically revise the existing content without getting drawn
into a big rewrite, but in some cases the content was either pretty
unsalvageable (due to talking about obsolete features that were removed
long ago) or required some broader changes to make the result hopefully
still get the same facts across. In those cases I've both removed some
content entirely or adjusted larger paragraphs.
This was not an exhaustive review and so I'm sure there's still plenty of
room for similar improvements elsewhere. I also resisted the urge to
update some pages that contain outdated information about currently-active
features.
My initial motivation here was to update the example output from
Terraform's top-level help list to match recent updates in the layout
and language used.
However, while here I took the opportunity to update some dated language
that was not consistent with our modern documentation writing style,
in particular including a totally unnecessary and potentially-alienating
claim that Terraform is "very easy to use". Our modern writing style
discourages this sort of "boastful" language and encourages us to focus on
the facts at hand.
This just reduces the amount of space between different elements on in the
main help output from four columns to two. The main motivation here was
to give some of the longer command descriptions a little more horizontal
breathing room, but subjectively I also find the tighter column gutters
easier to scan. Others may disagree, of course.
The short description of our commands (as shown in the main help output
from "terraform") was previously very inconsistent, using different
tense/mood for different commands. Some of the commands were also using
some terminology choices inconsistent with how we currently talk about
the related ideas in our documentation.
Here I've tried to add some consistency by first rewriting them all in
the imperative mood (except the ones that just are just subcommand
groupings), and tweaking some of the terminology to hopefully gel better
with how we present similar ideas in our recently-updated docs.
While working on this I inevitably spotted some similar inconsistencies
in the longer-form help output of some of the commands. I've not reviewed
all of these for consistency, but I did update some where the wording
was either left inconsstent with the short form changes I'd made or
where the prose stood out to me as particularly inconsistent with our
current usual documentation language style.
All of this is subjective, so I expect we'll continue to tweak these over
time as we continue to develop our documentation writing style based on
user questions and feedback.
A long time ago we introduced this separation between "common commands"
and "all other commands", but over the intervening years we've not really
done a good job of classifying new commands we've added and so by default
most of them ended up being classified as "common".
In the interests of making this output more useful for those getting
started, this switches the two categories so that "Main commands" is now
the curated list, and "all other commands" is the bucket for everything
else.
The intent here is that the "main commands" are the ones users are likely
to try as part of their initial learning of Terraform, while the other
commands are for less common situations where the user is more likely to
learn about a specific command in some other context, like a tutorial
about a special situation.
The "main commands" are also now ordered by the sequence users will
typically run them in, rather than alphabetical order. That's a subjective
readability tradeoff, but I think as long as the list stays relatively
short (which it should) it's still relatively easy to scan and find a
particular command in the shortlist.
These are commands that either no longer do anything aside from emitting
an error message or are just backward-compatibility aliases for other
commands.
This generalizes our previous situation where we were specifically
hiding "internal-plugin", and does so in a way that fixes the
long-standing cosmetic bug that the column width in the help output was
chosen based on the hidden command "internal-plugin", which is
unfortunately also the longest command in our command set.
Create a logger that will record any apparent crash output for later
processing.
If the cli command returns with a non-zero exit status, check for any
recorded crashes and add those to the output.
Terraform does not use rpc errors for any error communication, so these
are always something that went wrong in outside of the plugin protocol.
The most common example of which is a provider crash, which would return
"rpc error: code = Unavailable desc = transport is closing". Replace
these error codes with something a little more presentable for the user,
and insert the calling method name to help correlate it to the
operation that failed.
This is an analog to the "alltrue" function, using OR as the reduce
operator rather than AND.
This also includes some simplification of the "alltrue" implementation
to implement it similarly as a sort of reduce operation with AND
as the reduce operator, but with the same effective behavior.
We have informational mode enabled for pull requests. This commit
enables it for individual commits, too.
Informational mode registers the result of a Codecov check without ever
failing due to low coverage. This is appropriate for Terraform because
much of the test coverage comes from cross-package tests, which Codecov
misses.

Now that hclog can independently set levels on related loggers, we can
separate the log levels for different subsystems in terraform.
This adds the new environment variables, `TF_LOG_CORE` and
`TF_LOG_PROVIDER`, which each take the same set of log level arguments,
and only applies to logs from that subsystem. This means that setting
`TF_LOG_CORE=level` will not show logs from providers, and
`TF_LOG_PROVIDER=level` will not show logs from core. The behavior of
`TF_LOG` alone does not change.
While it is not necessarily needed since the default is to disable logs,
there is also a new level argument of `off`, which reflects the
associated level in hclog.
Added an Off level to hclog, so we can individually disable logging at
various levels.
Added IndependentLevels so that sublogger levels are not linked to their
parents.

When reading this page, I couldn't find the list of the "supported backends to the left". They're actually on a different page, so thought I'd update it so that others wouldn't find it confusing like me.
If this is ok with you, would it be possible to label this PR with 'hacktoberfest-accepted'? I'm still new to this. If not, I'd be alright. Thank you!

A set of version constraints can contain duplicates. This can happen if
multiple identical constraints are specified throughout a configuration.
When rendering the set, it is confusing to display redundant
constraints. This commit changes the string renderer to only show the
first instance of a given constraint, and adds unit tests for this
function to cover this change.
This also fixes a bug with the locks file generation: previously, a
configuration with redundant constraints would result in this error on
second init:
Error: Invalid provider version constraints
on .terraform.lock.hcl line 6:
(source code not available)
The recorded version constraints for provider
registry.terraform.io/hashicorp/random must be written in normalized form:
"3.0.0".
Some tests could not handle reading orphaned resources. It also turns
out the ReadResource mock never returned the correct state in the
default case at all.
This forces orphaned resources to be re-read during planning, removing
them from the state if they no longer exist.
This needs to be done for a bare `refresh` execution, since Terraform
should remove instances that don't exist and are not in the
configuration from the state. They should also be removed from state so
there is no Delete change planned, as not all providers will gracefully
handle a delete operation on a resource that does not exist.
Use a separate log sink to always capture trace logs for the panicwrap
handler to write out in a crash log.
This requires creating a log file in the outer process and passing that
path to the child process to log to.
