From 31d95b867919b02774f4a98b25d2f997c2985600 Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Thu, 9 Feb 2012 04:14:06 +0100 Subject: Print error message when to-be-downloaded file cannot be created It can happen that the to-be-downloaded file cannot be created in cachedir. For example, I am an -Sup user, and it is comfortable to set --cachedir to /mnt/pendrive, which is a FAT filesystem, so files like capseo-1:0.3-2-i686.pkg.tar.xz cannot be downloaded to there. Before this patch, pacman didn't give clear output about what happens when the download code could not create the necessary file. This can be confusing with -Su. An example output: *** $ sudo pacman -S capseo bochs --cachedir /c/TEMP resolving dependencies... looking for inter-conflicts... Targets (2): bochs-2.4.6-1 capseo-1:0.3-2 Total Download Size: 0.61 MiB Total Installed Size: 2.61 MiB Proceed with installation? [Y/n] :: Retrieving packages from extra... warning: failed to retrieve some files from extra bochs-2.4.6-1-i686 611.5 KiB 118K/s 00:05 [------------------] 97% error: failed to commit transaction (unexpected error) Errors occurred, no packages were upgraded. *** After the patch, pacman will give more informative error message (and pm_errno is set properly): *** error: could not open file '/c/TEMP/capseo-1:0.3-2-i686.pkg.tar.xz.part': Invalid argument error: failed to commit transaction (failed to retrieve some files) *** Unfortunately, the "could not open file" error message is printed for every mirror (that can be dozens of lines), which is ugly, but at least informative... Without modifying the download logic (for example, by introducing -2 return value for _alpm_download() to indicate giving up), this ugliness cannot be eliminated.
