From 2d79191c97e8ee965bfea1feef03de26c839dc8a Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Sun, 1 Jan 2012 18:49:59 -0500 Subject: commitpkg: behavior more sanely in searching for built pkgs In the case of a .pkg.tar.xz and a .pkg.tar.gz existing in the same directory, all commitpkg would say is: ==> WARNING: Could not find . Skipping x86_64 Upon digging into the logic, we did a few things poorly, mostly in getpkgfile: - getpkgfile tried to die in a subshell (within the command substituion assignment to 'pkgfile'). This will never work. - We assumed that proper glob expansion happened when we received exactly 1 arg. This isn't necessarily true without nullglob in effect. - We dumped the real error (spewed by getpkgfile) to /dev/null. - We checked for the package twice in both $PWD and $DESTDIR/. - We checked for file existance multiple times. Address this by: - not hiding errors. revamp the wording a little bit to make it more obvious why we failed, particularly in the case of a glob expanding to more than 1 file. Logic here is simplified to pointing out the failure cases of 0 and >1. - setting nullglob so the number of arguments passed into getpkgfile is meaningful from a 'did it decisively resolve' point of view. - not trying to exit the entire script from a subshell. Just return a value (and use it). - avoiding the package file existance check afterwards. this is a freebie from getpkgfile when the glob passed fails to expand.
