Downloader rewriter config has all_blocked_message This allows for the config author to specify a useful error message to adorn the user-facing error, so that if the user is unaware or forgets about the config, they get a more clear error message than: ``` ERROR: java.io.IOException: Error downloading [] to /some/path ``` or ``` Error in download: java.io.IOException: Cache miss and no url specified ``` Currently there is a log line like: ``` INFO: Rewritten [https://doesnotexist.com/beep] as [] ``` printed, but this is often quite far from the error - this puts all the information in one place. If you don't configure an all_blocked_message, this now looks like: ``` ERROR: java.io.IOException: Cache miss and no url specified - Configured URL rewriter blocked all URLs: [https://doesnotexist.com/beep] ``` And if you do, it will look like something like: ``` ERROR: java.io.IOException: Cache miss and no url specified - Configured URL rewriter blocked all URLs: [https://doesnotexist.com/beep] - See https://mycorp.com/bazel-rewriter-issue for more details. ``` Closes #12997.
