Kristin Laemmert	1b8f4566fa	internal/initwd: fix panics with relative submodules in DirFromModule (#25250 ) * internal/initwd: fix panics with relative submodules in DirFromModule There were two related issues here: 1. panic with any local module with submodules 1. panic with a relative directory that was above the workdir ("../") The first panic was caused by the local installer looking up the root module with the (nonexistant) key "root.", instead of "". The second panic was caused by the installer trying to determine the relative path from ".". This was fixed by detecting "." as the source path and using the absolute path for the call to filepath.Rel. Added test cases for both panics and updated the existing e2e tests with the correct install paths.	6 years ago
Martin Atkins	072c6d9aed	internal/copydir: Factor out our recursive directory copy for reuse We've previously been copying this function around so it could remain unexported while being used in various packages. However, it's a non-trivial function with lots of specific assumptions built into it, so here we'll put it somewhere that other packages can depend on it _and_ document the assumptions it seems to be making for future reference. As a bonus, this now uses os.SameFile to detect when two paths point to the same physical file, instead of the slightly buggy local implementation we had before which only worked on Unix systems and did not correctly handle when the paths were on different physical devices. The copy of the function I extracted here is the one from internal/initwd, so this commit also includes the removal of that unexported version and updating the callers in that package to use at at this new location.	6 years ago
Martin Atkins	86c02d5c35	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.	7 years ago
