David Rodríguez 76de7a92b9 [rubygems/rubygems] Fix misleading error if compact index cannot be copied ... Previously if `~/.bundle/cache/compact_index/rubygems.org.*/version` were owned by root with read-only access, `bundle install` would fail with a misleading error message. For example: ``` There was an error while trying to write to `/tmp/bundler-compact-index-20220711-1823-npllre/versions`. It is likely that you need to grant write permissions for that path. ``` This happened because the EACCESS error was caught by `SharedHelpers.filesystem_access`, which makes it look like the target directory is at fault instead of the source. We can't simply drop this guard because that causes the opposite problem: the permission error appears to come from the source instead of the target, since `CompactIndexClient::Cache#lines` also wraps read access errors. Instead, bring a minimal implementation of `FileUtils.cp` and nest calls to `SharedHelpers.filesystem_access` properly. https://github.com/rubygems/rubygems/commit/320822c070 Co-authored-by: Stan Hu <stanhu@gmail.com>		2022-07-14 15:06:09 +09:00
