command: "terraform init" can partially initialize for 0.12upgrade There are a few constructs from 0.11 and prior that cause 0.12 parsing to fail altogether, which previously created a chicken/egg problem because we need to install the providers in order to run "terraform 0.12upgrade" and thus fix the problem. This changes "terraform init" to use the new "early configuration" loader for module and provider installation. This is built on the more permissive parser in the terraform-config-inspect package, and so it allows us to read out the top-level blocks from the configuration while accepting legacy HCL syntax. In the long run this will let us do version compatibility detection before attempting a "real" config load, giving us better error messages for any future syntax additions, but in the short term the key thing is that it allows us to install the dependencies even if the configuration isn't fully valid. Because backend init still requires full configuration, this introduces a new mode of terraform init where it detects heuristically if it seems like we need to do a configuration upgrade and does a partial init if so, before finally directing the user to run "terraform 0.12upgrade" before running any other commands. The heuristic here is based on two assumptions: - If the "early" loader finds no errors but the normal loader does, the configuration is likely to be valid for Terraform 0.11 but not 0.12. - If there's already a version constraint in the configuration that excludes Terraform versions prior to v0.12 then the configuration is probably _already_ upgraded and so it's just a normal syntax error, even if the early loader didn't detect it. Once the upgrade process is removed in 0.13.0 (users will be required to go stepwise 0.11 -> 0.12 -> 0.13 to upgrade after that), some of this can be simplified to remove that special mode, but the idea of doing the dependency version checks against the liberal parser will remain valuable to increase our chances of reporting version-based incompatibilities rather than syntax errors as we add new features in future.

command: new cache directory .terraform/providers for providers Terraform v0.10 introduced .terraform/plugins as a cache directory for automatically-installed plugins, Terraform v0.13 later reorganized the directory structure inside but retained its purpose as a cache. The local cache used to also serve as a record of specifically which packages were selected in a particular working directory, with the intent that a second run of "terraform init" would always select the same packages again. That meant that in some sense it behaved a bit like a local filesystem mirror directory, even though that wasn't its intended purpose. Due to some unfortunate miscommunications, somewhere a long the line we published some documentation that _recommended_ using the cache directory as if it were a filesystem mirror directory when working with Terraform Cloud. That was really only working as an accident of implementation details, and Terraform v0.14 is now going to break that because the source of record for the currently-selected provider versions is now the public-facing dependency lock file rather than the contents of an existing local cache directory on disk. After some consideration of how to move forward here, this commit implements a compromise that tries to avoid silently doing anything surprising while still giving useful guidance to folks who were previously using the unsupported strategy. Specifically: - The local cache directory will now be .terraform/providers rather than .terraform/plugins, because .terraform/plugins is effectively "poisoned" by the incorrect usage that we can't reliably distinguish from prior version correct usage. - The .terraform/plugins directory is now the "legacy cache directory". It is intentionally _not_ now a filesystem mirror directory, because that would risk incorrectly interpreting providers automatically installed by Terraform v0.13 as if they were a local mirror, and thus upgrades and checksum fetches from the origin registry would be blocked. - Because of the previous two points, someone who _was_ trying to use the legacy cache directory as a filesystem mirror would see installation fail for any providers they manually added to the legacy directory. To avoid leaving that user stumped as to what went wrong, there's a heuristic for the case where a non-official provider fails installation and yet we can see it in the legacy cache directory. If that heuristic matches then we'll produce a warning message hinting to move the provider under the terraform.d/plugins directory, which is a _correct_ location for "bundled" provider plugins that belong only to a single configuration (as opposed to being installed globally on a system). This does unfortunately mean that anyone who was following the incorrectly-documented pattern will now encounter an error (and the aforementioned warning hint) after upgrading to Terraform v0.14. This seems like the safest compromise because Terraform can't automatically infer the intent of files it finds in .terraform/plugins in order to decide automatically how best to handle them. The internals of the .terraform directory are always considered implementation detail for a particular Terraform version and so switching to a new directory for the _actual_ cache directory fits within our usual set of guarantees, though it's definitely non-ideal in isolation but okay when taken in the broader context of this problem, where the alternative would be silent misbehavior when upgrading.

command: new cache directory .terraform/providers for providers Terraform v0.10 introduced .terraform/plugins as a cache directory for automatically-installed plugins, Terraform v0.13 later reorganized the directory structure inside but retained its purpose as a cache. The local cache used to also serve as a record of specifically which packages were selected in a particular working directory, with the intent that a second run of "terraform init" would always select the same packages again. That meant that in some sense it behaved a bit like a local filesystem mirror directory, even though that wasn't its intended purpose. Due to some unfortunate miscommunications, somewhere a long the line we published some documentation that _recommended_ using the cache directory as if it were a filesystem mirror directory when working with Terraform Cloud. That was really only working as an accident of implementation details, and Terraform v0.14 is now going to break that because the source of record for the currently-selected provider versions is now the public-facing dependency lock file rather than the contents of an existing local cache directory on disk. After some consideration of how to move forward here, this commit implements a compromise that tries to avoid silently doing anything surprising while still giving useful guidance to folks who were previously using the unsupported strategy. Specifically: - The local cache directory will now be .terraform/providers rather than .terraform/plugins, because .terraform/plugins is effectively "poisoned" by the incorrect usage that we can't reliably distinguish from prior version correct usage. - The .terraform/plugins directory is now the "legacy cache directory". It is intentionally _not_ now a filesystem mirror directory, because that would risk incorrectly interpreting providers automatically installed by Terraform v0.13 as if they were a local mirror, and thus upgrades and checksum fetches from the origin registry would be blocked. - Because of the previous two points, someone who _was_ trying to use the legacy cache directory as a filesystem mirror would see installation fail for any providers they manually added to the legacy directory. To avoid leaving that user stumped as to what went wrong, there's a heuristic for the case where a non-official provider fails installation and yet we can see it in the legacy cache directory. If that heuristic matches then we'll produce a warning message hinting to move the provider under the terraform.d/plugins directory, which is a _correct_ location for "bundled" provider plugins that belong only to a single configuration (as opposed to being installed globally on a system). This does unfortunately mean that anyone who was following the incorrectly-documented pattern will now encounter an error (and the aforementioned warning hint) after upgrading to Terraform v0.14. This seems like the safest compromise because Terraform can't automatically infer the intent of files it finds in .terraform/plugins in order to decide automatically how best to handle them. The internals of the .terraform directory are always considered implementation detail for a particular Terraform version and so switching to a new directory for the _actual_ cache directory fits within our usual set of guarantees, though it's definitely non-ideal in isolation but okay when taken in the broader context of this problem, where the alternative would be silent misbehavior when upgrading.

After some consideration of how to move forward here, this commit implements a compromise that tries to avoid silently doing anything surprising while still giving useful guidance to folks who were previously using the unsupported strategy. Specifically: - The local cache directory will now be .terraform/providers rather than .terraform/plugins, because .terraform/plugins is effectively "poisoned" by the incorrect usage that we can't reliably distinguish from prior version correct usage. - The .terraform/plugins directory is now the "legacy cache directory". It is intentionally _not_ now a filesystem mirror directory, because that would risk incorrectly interpreting providers automatically installed by Terraform v0.13 as if they were a local mirror, and thus upgrades and checksum fetches from the origin registry would be blocked. - Because of the previous two points, someone who _was_ trying to use the legacy cache directory as a filesystem mirror would see installation fail for any providers they manually added to the legacy directory. To avoid leaving that user stumped as to what went wrong, there's a heuristic for the case where a non-official provider fails installation and yet we can see it in the legacy cache directory. If that heuristic matches then we'll produce a warning message hinting to move the provider under the terraform.d/plugins directory, which is a _correct_ location for "bundled" provider plugins that belong only to a single configuration (as opposed to being installed globally on a system). This does unfortunately mean that anyone who was following the incorrectly-documented pattern will now encounter an error (and the aforementioned warning hint) after upgrading to Terraform v0.14. This seems like the safest compromise because Terraform can't automatically infer the intent of files it finds in .terraform/plugins in order to decide automatically how best to handle them. The internals of the .terraform directory are always considered implementation detail for a particular Terraform version and so switching to a new directory for the _actual_ cache directory fits within our usual set of guarantees, though it's definitely non-ideal in isolation but okay when taken in the broader context of this problem, where the alternative would be silent misbehavior when upgrading.

command: "terraform init" can partially initialize for 0.12upgrade There are a few constructs from 0.11 and prior that cause 0.12 parsing to fail altogether, which previously created a chicken/egg problem because we need to install the providers in order to run "terraform 0.12upgrade" and thus fix the problem. This changes "terraform init" to use the new "early configuration" loader for module and provider installation. This is built on the more permissive parser in the terraform-config-inspect package, and so it allows us to read out the top-level blocks from the configuration while accepting legacy HCL syntax. In the long run this will let us do version compatibility detection before attempting a "real" config load, giving us better error messages for any future syntax additions, but in the short term the key thing is that it allows us to install the dependencies even if the configuration isn't fully valid. Because backend init still requires full configuration, this introduces a new mode of terraform init where it detects heuristically if it seems like we need to do a configuration upgrade and does a partial init if so, before finally directing the user to run "terraform 0.12upgrade" before running any other commands. The heuristic here is based on two assumptions: - If the "early" loader finds no errors but the normal loader does, the configuration is likely to be valid for Terraform 0.11 but not 0.12. - If there's already a version constraint in the configuration that excludes Terraform versions prior to v0.12 then the configuration is probably _already_ upgraded and so it's just a normal syntax error, even if the early loader didn't detect it. Once the upgrade process is removed in 0.13.0 (users will be required to go stepwise 0.11 -> 0.12 -> 0.13 to upgrade after that), some of this can be simplified to remove that special mode, but the idea of doing the dependency version checks against the liberal parser will remain valuable to increase our chances of reporting version-based incompatibilities rather than syntax errors as we add new features in future.

command: new cache directory .terraform/providers for providers Terraform v0.10 introduced .terraform/plugins as a cache directory for automatically-installed plugins, Terraform v0.13 later reorganized the directory structure inside but retained its purpose as a cache. The local cache used to also serve as a record of specifically which packages were selected in a particular working directory, with the intent that a second run of "terraform init" would always select the same packages again. That meant that in some sense it behaved a bit like a local filesystem mirror directory, even though that wasn't its intended purpose. Due to some unfortunate miscommunications, somewhere a long the line we published some documentation that _recommended_ using the cache directory as if it were a filesystem mirror directory when working with Terraform Cloud. That was really only working as an accident of implementation details, and Terraform v0.14 is now going to break that because the source of record for the currently-selected provider versions is now the public-facing dependency lock file rather than the contents of an existing local cache directory on disk. After some consideration of how to move forward here, this commit implements a compromise that tries to avoid silently doing anything surprising while still giving useful guidance to folks who were previously using the unsupported strategy. Specifically: - The local cache directory will now be .terraform/providers rather than .terraform/plugins, because .terraform/plugins is effectively "poisoned" by the incorrect usage that we can't reliably distinguish from prior version correct usage. - The .terraform/plugins directory is now the "legacy cache directory". It is intentionally _not_ now a filesystem mirror directory, because that would risk incorrectly interpreting providers automatically installed by Terraform v0.13 as if they were a local mirror, and thus upgrades and checksum fetches from the origin registry would be blocked. - Because of the previous two points, someone who _was_ trying to use the legacy cache directory as a filesystem mirror would see installation fail for any providers they manually added to the legacy directory. To avoid leaving that user stumped as to what went wrong, there's a heuristic for the case where a non-official provider fails installation and yet we can see it in the legacy cache directory. If that heuristic matches then we'll produce a warning message hinting to move the provider under the terraform.d/plugins directory, which is a _correct_ location for "bundled" provider plugins that belong only to a single configuration (as opposed to being installed globally on a system). This does unfortunately mean that anyone who was following the incorrectly-documented pattern will now encounter an error (and the aforementioned warning hint) after upgrading to Terraform v0.14. This seems like the safest compromise because Terraform can't automatically infer the intent of files it finds in .terraform/plugins in order to decide automatically how best to handle them. The internals of the .terraform directory are always considered implementation detail for a particular Terraform version and so switching to a new directory for the _actual_ cache directory fits within our usual set of guarantees, though it's definitely non-ideal in isolation but okay when taken in the broader context of this problem, where the alternative would be silent misbehavior when upgrading.
