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.
The main process is now handling what output to print, so it doesn't do
any good to try and run it through prefixedio, which is only adding
extra coordination to echo the same data.

If a change exists for a resource instance,
the After value is returned, however, this value
will not have its marks as it as been encoded.
This Marks the return value so the marks follow
that resource reference.
These were initially introduced as functions with "encode" and "decode"
prefixes, but that doesn't match with our existing convention of putting
the encoding format first so that the encode and decode functions will
group together in a alphabetically-ordered function list.
"text" is not really a defined serialization format, but it's a short word
that hopefully represents well enough what these functions are aiming to
encode and decode, while being consistent with existing functions like
jsonencode/jsondecode, yamlencode/yamldecode, etc.
The "base64" at the end here is less convincing because there is precedent
for that modifier to appear both at the beginning and the end in our
existing function names. I chose to put it at the end here because that
seems to be our emergent convention for situations where the base64
encoding is a sort of secondary modifier alongside the primary purpose
of the function, as we see with "filebase64". (base64gzip is an exception
here, but it seems outvoted by the others.)
Previously this codepath was generating a confusing message in the absense
of any symlinks, because filepath.EvalSymlinks returns a successful result
if the target isn't a symlink.
Now we'll emit the log line only if filepath.EvalSymlinks returns a
result that's different in a way that isn't purely syntactic (which
filepath.Clean would "fix").
The new message is a little more generic because technically we've not
actually ensured that a difference here was caused by a symlink and so
we shouldn't over-promise and generate something potentially misleading.
If you run the e2etests locally and use a configured plugin_cache_dir,
the test will leave a bad directory behind in your cache dir that causes
later `init`s to fail. To circumvent this, pass an explicity-empty CLI
config file.
This is a nicety for local developers and not necessarily required, but
it happens to me often enough that I'd like to fix it. It's probably not
a *bad* idea to pass an explicit cli config to all e2etests, honestly,
but this is the only one that causes active problems so I limited this
PR to that one test.
Here's the error which occurs on subsequent `init` if this test is run on a
machine that uses a plugin cache dir:
2020/10/13 10:41:05 [TRACE] providercache.fillMetaCache: error while scanning directory /Users/mildwonkey/.terraform.d/plugin-cache: failed to read metadata about /Users/mildwonkey/.terraform.d/plugin-cache/example.com/awesomecorp/happycloud/1.2.0/darwin_amd64: stat /Users/mildwonkey/.terraform.d/plugin-cache/example.com/awesomecorp/happycloud/1.2.0/darwin_amd64: no such file or directory
ioutil.TempFile has a special case where an empty string for its dir
argument is interpreted as a request to automatically look up the system
temporary directory, which is commonly /tmp .
We don't want that behavior here because we're specifically trying to
create the temporary file in the same directory as the file we're hoping
to replace. If the file gets created in /tmp then it might be on a
different device and thus the later atomic rename won't work.
Instead, we'll add our own special case to explicitly use "." when the
given filename is in the current working directory. That overrides the
special automatic behavior of ioutil.TempFile and thus forces the
behavior we need.
This hadn't previously mattered for earlier callers of this code because
they were creating files in subdirectories, but this codepath was failing
for the dependency lock file due to it always being created directly
in the current working directory.
Unfortunately since this is a picky implementation detail I couldn't find
a good way to write a unit test for it without considerable refactoring.
Instead, I verified manually that the temporary filename wasn't in /tmp on
my Linux system, and hope that the comment inline will explain this
situation well enough to avoid an accidental regression in future
maintenence.
