Bug 8832 – epm -qf doesn't work without full path

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Bill Gjestvang 2002-10-06 22:56:49 UTC]

"epm -qf" doesn't work unless you prepend the path to the filename.

This can lead people to assume that a file is not owned by any package, when in
fact it is.

Example:
$ cd /etc
$ epm -qf man.conf
file man.conf is not owned by any package
$ epm -qf /etc/man.conf
man-1.5k

Expected behavior:
$ cd /etc
$ epm -qf man.conf
man-1.5k

This is a deliberate design feature that is contestable. I guess we should at
least add a flag to have it do more lenient searches.

[Comment 2 Bill Gjestvang 2002-10-31 20:23:54 UTC]

It's definitely different behavior than rpm.
Here's how rpm-4.0.4-7x.18 works on RedHat 7.3:

$ cd /etc
$ rpm -qf man.config
man-1.5j-6

$ cd /
$ rpm -qf man.config
error: file man.config: No such file or directory
$ rpm -qf /etc/man.config
man-1.5j-6

Another fairly tiny issue. I think epm -qf should do whatever rpm -qf does. Do
you have time to check out how rpm -qf works, and try to imitate it ?

hi!

this was no python code... ;)

but cuz of it my perl-skill got an 'upgrade' *G*

greetings, LordVan

here's a diff:

<       #       the full pathname
<       if ($a !~ m#^/#) { }

>       ## if no '/' in file-name add one at the beginning to match the regex
later correct
>       if ($a !~ m|/|) { $a="/$a" }

Created attachment 6782 [details, diff]
Make "epm -qf relname" work

This patch uses the "Cwd" perl module to figure out the absolute path of a
relative argument (including collapsing ".." elements).

Thanks Wayne for the patch.  It's in the tree now as 0.8.2 along with
your other patches.  I'm sorry these didn't get in for so long; I
never saw them in bugzilla.  If you have further patches I'll get them
in as quick as I can.

[Comment 7 Bill Gjestvang 2003-04-30 23:43:34 UTC]

epm should first check whether the file exists.

"epm -qf nonexistentfile"
   returns
"file $PWD/nonexistentfile is not owned by any package"
(e.g. in /usr/bin, returns "file /usr/bin/nonexistentfile is not...")

rpm, for a similar request, returns
"error: file nonexistentfile: No such file or directory"

(But the behavior is much improved from before.)

Thanks Bill for the nit pick. ;-)  All fixed in 0.8.3
