 Posted: Sat Mar 23, 2024 11:40 am Post subject: location of files and what does portage know |
 |
|
With the following issue https://github.com/portagefilelist/client/issues/55 a maybe problem came up and now I want to know how to handle it.
If the user runs which ip it will return /usr/bin/ip. A e-file /usr/bin/ip does return northing. Why, because portage records only /bin/ip and not /usr/bin/ip.?
Is this the corret behavior, or does this come from installing the ip command before the usr-merge?
Would any new installation of the ip command will place it into /usr/bin and have not this issue?

Banana,
On my [49] default/linux/amd64/23.0/split-usr/no-multilib (stable) * install I get a different answer to you.
| Code: | neddy_static ~ # which ip
/bin/ip
neddy_static ~ # e-file /bin/ip
[I] sys-apps/iproute2
Seen Versions: 5.4.0 6.3.0 6.4.0 6.5.0 6.6.0 6.6.0-r1 6.6.0-r2 6.6.0-r3 9999
Portage Versions: 6.6.06.6.0-r16.6.0-r39999
Repository: gentoo
Installed Versions: 6.6.0-r3(Sat Mar 16 16:36:18 2024)
Homepage: https://wiki.linuxfoundation.org/networking/iproute2
Description: kernel routing and traffic control utilities
Matched Files: /bin/ip |
I'm not sure if that helps, is just makes the question more complex.

This seems to not be the case (ip is put in /usr/bin because of /bin symlink - I see this during emerge, but equery doesn't know what owns it - I did merge-usr yesterday, | Code: | --- replaced dir /lib64/tc
--- cfgpro dir /lib64
--- replaced obj /bin/ss
--- replaced obj /bin/ip
--- cfgpro dir /bin
ns ~ # which ip
/usr/bin/ip
ns ~ # equery b /usr/bin/ip
* Searching for /usr/bin/ip ... |
Both before and after an | Code: | | emerge -va1 iproute2 |
And I'm running [31] default/linux/amd64/23.0/no-multilib/hardened (stable) * now
Seems te be an merge-usr issue - so question is, how do we now identify what ebuild/package a file belongs to? (I guess this would affect all ebuilds installing into /lib, /lib64, /bin and /sbin which are now symlinks?) |

This has nothing to do with merged-usr. "which" always had the "problem" ... try parameter "-a" ... which of them is only a softlink you have to find out yourself  :
| Code: | $ which mail
/usr/bin/mail
$
$ which -a mail
/usr/bin/mail
/bin/mail |

And that would still leave the user to go through each hit with e-file/equery to find out which is the right one to use for searching for owner - anyways for me which -a only returns the /usr/bin/ location | Code: | ns ~ # which -a mail
/usr/bin/mail
ns ~ # which -a ip
/usr/bin/ip |
/bin and /sbin isn't in $PATH

Strange ... I get always an answer:
| Code: | $ equery b /usr/bin/mail
* Searching for /usr/bin/mail ...
net-mail/mailutils-3.15 (/usr/bin/mail)
/bin $
/bin $ equery b /bin/mail
* Searching for /bin/mail ...
net-mail/mailutils-3.15 (/usr/bin/mail)
net-mail/mailutils-3.15 (/bin/mail -> ../usr/bin/mail) |

I can force - more or less - the same behaviour by manually adding /bin and /sbin to $PATH | Code: | ns /etc/env.d # env-update && source /etc/profile
>>> Regenerating /etc/ld.so.cache...
-bash: TMOUT: readonly variable
ns /etc/env.d # echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/bin:/opt/bin:/bin:/sbin
ns /etc/env.d # which -a mail
/usr/bin/mail
/bin/mail
/sbin/mail
ns /etc/env.d # equery b /sbin/mail
* Searching for /sbin/mail ...
mail-client/mailx-8.1.2.20180807-r1 (/usr/bin/mail)
ns /etc/env.d # equery b /bin/mail
* Searching for /bin/mail ...
mail-client/mailx-8.1.2.20180807-r1 (/usr/bin/mail) |
Notice my equery output doesn't show the linked line like yours do? |

@Neddy
This is what I also can observe and asume that sys-apps/iproute2 installs ip in /bin/ip and thus pfl collects it. It uses portage.db[eroot]['vartree'].dbapi from the portage python package. https://dev.gentoo.org/~zmedico/portage/doc/api/
@freke
Thanks for the validation. Since I'm on a usr-merged a long time, I could not verify this.
So the portage api knows the initial paths from the install, but nothing more and in a usr-merged enviroment it does not know the symlinks. Is there a way to detect the symlinks, or would this mess things up?

Don't know - I've created this after my first reply in this thread - https://bugs.gentoo.org/927640 |

Just did this:
| Code: | ❯ which -a ip
/usr/bin/ip
❯ equery b /usr/bin/ip
* Searching for /usr/bin/ip ...
❯ equery b /bin/ip
* Searching for /bin/ip ...
sys-apps/iproute2-6.6.0-r3 (/bin/ip) |
Kind of different than pietinger got but matches what pfl records and stores for e-file (I do not have mail installed so I use another command)
