From bd3d1a17c2ec4297f05d092f0b93d025f811aa8a Mon Sep 17 00:00:00 2001 From: Olivier Brunel Date: Fri, 10 Jan 2014 16:25:17 +0100 Subject: Add events _PKGDOWNLOAD_{START, DONE, FAILED} These will be emmitted when download a package file from a repository, indicating that the download starts, and whether it was successfull or not. Note that when multiple servers are available, no event is emmitted when switching to another server. (This doesn't apply to alpm_fetch_pkgurl(), but since it is called by the frontend, it shouldn't have problems knowing when the download starts and when it ends.)
