[pacman-dev] [PATCH] Do not warn about missing files in NoExtract
by Allan McRae 21 Dec '15

21 Dec '15

The CheckSpace option checks the size of all files in a package being replaced and gives a warning when it can not read the file. However, files in NoExtract are expected to be missing and should not be warned about. Fixes FS#47470.

This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "The official pacman repository".
