| This directory contains the hashes of tar.gz files uploaded to cloud storage. |
| Hooks in the DEPS files run "download_from_google_storage" to download these |
| tarfiles, and unpack them. These tar files contain a stable Dart SDK, which |
| is used to build the observatory and to run the test scripts. |
| |
| The hooks use the --auto-platform feature, so that only the SDK for the |
| current platform (linux, macos, or windows) is downloaded. This requires |
| the subdirectories to have the special names "linux", "win", and "mac", which |
| the download script is hardcoded to recognize. |
| |
| The linux SDK has three extra dart executables added to the bin directory. |
| 'dart-mips', 'dart-arm', and 'dart-arm64' are executables compiled to run on |
| mips, arm, and arm64 (aarch64) processors, respectively. |
| |
| To upload new versions of these tar files, use the "upload_to_google_storage" |
| tool in depot_tools, and download the new stable SDKs from the dartlang.org |
| web page. The mips and arm executables must be copied from the machines that |
| build them, and stripped. There should be no need to update these tar files |
| for every new stable version of Dart. |
