Martin Atkins	039d2c28a2	internal/providercache: Clear the metadata cache during package install This was previously happening during linking from another cache, but not when installing an entirely new provider.	6 years ago
Martin Atkins	537c1bedcf	internal/providercache: LinkFromOtherCache removes target, not source This was incorrectly removing the _source_ entry prior to creating the symlink, therefore ending up with a dangling symlink and no source file. This wasn't obvious before because the test case for LinkFromOtherCache was also incorrectly named and therefore wasn't running. Fixing the name of that test made this problem apparent. The TestLinkFromOtherCache test case now ends up seeing the final resolved directory rather than the symlink target, because of upstream changes to the internal/getproviders filesystem scanning logic to handle symlinks properly.	6 years ago
Martin Atkins	ad15459468	internal/{getproviders,providercache}: improved trace logging There's a lot going on in these functions that can be hard to follow from the outside, so we'll add some additional trace logging so that we can more easily understand why things are behaving the way they are.	6 years ago
Martin Atkins	807267d1b5	internal/providercache: Installation from HTTP URLs and local archives When a provider source produces an HTTP URL location we'll expect it to resolve to a zip file, which we'll first download to a temporary directory and then treat it like a local archive. When a provider source produces a local archive path we'll expect it to be a zip file and extract it into the target directory. This does not yet include an implementation of installing from an already-unpacked local directory. That will follow in a subsequent commit, likely following a similar principle as in Dir.LinkFromOtherCache.	6 years ago
Martin Atkins	e4d14324e0	internal/providercache: Stub of Dir.InstallPackage method This will eventually be responsible for actually retrieving a package from a source and then installing it into the cache directory, but for the moment it's just a stub to complete the proposed API, which I intend to test in a subsequent commit by writing the full "Installer" API that will encapsulate the full installation logic.	6 years ago
Martin Atkins	67ca067910	internal/providercache: Linking from one cache to another When a system-wide shared plugin cache is configured, we'll want to make use of entries already in the shared cache when populating a local (configuration-specific) cache. This new method LinkFromOtherCache encapsulates the work of placing a link from one cache to another. If possible it will create a symlink, therefore retaining a key advantage of configuring a shared plugin cache, but otherwise we'll do a deep copy of the package directory from one cache to the other. Our old provider installer would always skip trying to create symlinks on Windows because Go standard library support for os.Symlink on Windows was inconsistent in older versions. However, os.Symlink can now create symlinks using a new API introduced in a Windows 10 update and cleanly fail if symlink creation is impossible, so it's safe for us to just try to create the symlink and react if that produces an error, just as we used to do on non-Windows systems when possibly creating symlinks on filesystems that cannot support them.	6 years ago
