Description MMacD 2017-05-03 11:22:56 UTC
(10.3 2017Q2) When I did a pan-upgrade, pkg deleted xfce desktop but did not replace it (it really should *not* delete anything til after it has done the replacement). So I had this big gray background and had to figure out what happened and then re-install by hand. For some reason not obvious to me, the xfce desktop package includes samba44. I already had 46 installed, but pkg - didn't check for a later version - downloaded 44 - THEN discovered 46 and complained - downloaded ANOTHER copy of 46 - installed 44 anyway - THEN tried to re-install 46 and failed, complaining. That's a lot of confusion, and ended with the wrong version installed. Packages should not be made of unrelated parts, for a start. At least 2 of the 4 pieces in the package are unrelated to the desktop. pkg should preferably allow parts to be knocked out of the install, rather than make it a yes-no all-or-nothing choice. And it should definitely check, *before* downloading, whether the install would replace a later version with an earlier and avoid doing that. ============= 6:42:15 Wed, 03 May [momcat:root]~> pkg install xfce4-desktop-4.12.3_2 Updating FreeBSD repository catalogue...

Here's an example of why it's a Bad Idea to package unrelated software. Now I can't restore samba46 without having the newly-reinstalled desktop removed too! 7:29:16 Wed, 03 May [momcat:root]~> pkg install samba46 Updating FreeBSD repository catalogue...

Comment 2 Baptiste Daroussin 2017-05-03 13:03:26 UTC
this is not a pkg bug, but an infrastructure bug. samba44 is not an older version of samba46 from pkg point of view this is 2 different software: 2 different names. the library provided by samba44 and samba46 cannot be replaced on binaries as they are do not have the same ABI (iirc). The right solution to avoid such situation is to have a package (only one providing) the default client part: only libraries might be ok. and the other samba ports to be installed elsewhere: /usr/local/samba<version> or with a symlink in /usr/local/bin for all the binaries (suffixed by the version) so they don't conflict with each others and their binaries using a proper RPATH so they find their libs in /usr/local/samba<version>/lib before anything else. That way the user could decide which version of samba they want to install/use and whatever is the version of the libsmb used by default by other packages.

From pkg's current viewpoint 44 might be different to 46 rather than older, but that just means the naming conventions need to be fixed! The fact that 44 and 46 may be on different development paths is somewhat unimportant in the context of what the sysmgr chose to install. The sysmgr probably didn't just flip a coin, so casually overriding their choice is insensitive at best. Some apps/utils might have a number as part of their name root, but probably there are none with (e.g.) :::, so pkg could certainly determine that samba:::44-i.j.k whatever is the "same" product as samba:::46-i.j.k, and an older version that should not replace the newer one without special permission. And of course this is a general problem; samba just happened to be the one that got mugged this time.
