Previously we were only verifying locked hashes for local archive zip
files, but if we have non-ziphash hashes available then we can and should
also verify that a local directory matches at least one of them.
This does mean that folks using filesystem mirrors but yet also running
Terraform across multiple platforms will need to take some extra care to
ensure the hashes pass on all relevant platforms, which could mean using
"terraform providers lock" to pre-seed their lock files with hashes across
all platforms, or could mean using the "packed" directory layout for the
filesystem mirror so that Terraform will end up in the install-from-archive
codepath instead of this install-from-directory codepath, and can thus
verify ziphash too.
(There's no additional documentation about the above here because there's
already general information about this in the lock file documentation
due to some similar -- though not identical -- situations with network
mirrors.)
We previously had some tests for some happy paths and a few specific
failures into an empty directory with no existing locks, but we didn't
have tests for the installer respecting existing lock file entries.
This is a start on a more exhaustive set of tests for the installer,
aiming to visit as many of the possible codepaths as we can reasonably
test using this mocking strategy. (Some other codepaths require different
underlying source implementations, etc, so we'll have to visit those in
other tests separately.)
This won't be a typical usage pattern for normal code, but will be useful
for tests that need to work with locks as input so that they don't need to
write out a temporary file on disk just to read it back in immediately.
* Update module-registry-protocol.html.md
1: There is a mismatch in the segment labels for the version query URL (system vs provider)
2: There is a discrepancy between the documentation and the actual generated request for retrieving module source code (URL segments 4 vs 3)
- There is no segment for "provider"
* Update module-registry-protocol.html.md
Changed ```:system``` to ```:provider``` for versions and source API URLs
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.

And now some trailing spaces. le sigh
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.
* Update config.html.md
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".
