* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same. * removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context. * on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors. * added unit tests for step_download that are now CI tested on windows, mac & linux. * files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension` * since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted. * a download file is protected and locked by a file lock, * updated docs * updated go modules and vendors

// Package google provides support for making OAuth2 authorized and authenticated
|
|
// HTTP requests to Google APIs. It supports the Web server flow, client-side
|
|
// credentials, service accounts, Google Compute Engine service accounts, and Google
|
|
// App Engine service accounts.
|
|
//
|
|
// A brief overview of the package follows. For more information, please read
|
|
// https://developers.google.com/accounts/docs/OAuth2
|
|
// and
|
|
// https://developers.google.com/accounts/docs/application-default-credentials.
|
|
//
|
|
// OAuth2 Configs
|
|
//
|
|
// Two functions in this package return golang.org/x/oauth2.Config values from Google credential
|
|
// data. Google supports two JSON formats for OAuth2 credentials: one is handled by ConfigFromJSON,
|
|
// the other by JWTConfigFromJSON. The returned Config can be used to obtain a TokenSource or
|
|
// create an http.Client.
|
|
//
|
|
//
|
|
// Credentials
|
|
//
|
|
// The Credentials type represents Google credentials, including Application Default
|
|
// Credentials.
|
|
//
|
|
// Use FindDefaultCredentials to obtain Application Default Credentials.
|
|
// FindDefaultCredentials looks in some well-known places for a credentials file, and
|
|
// will call AppEngineTokenSource or ComputeTokenSource as needed.
|
|
//
|
|
// DefaultClient and DefaultTokenSource are convenience methods. They first call FindDefaultCredentials,
|
|
// then use the credentials to construct an http.Client or an oauth2.TokenSource.
|
|
//
|
|
// Use CredentialsFromJSON to obtain credentials from either of the two JSON formats
|
|
// described in OAuth2 Configs, above. The TokenSource in the returned value is the
|
|
// same as the one obtained from the oauth2.Config returned from ConfigFromJSON or
|
|
// JWTConfigFromJSON, but the Credentials may contain additional information
|
|
// that is useful is some circumstances.
