Bug 80041 – net-analyzer/net-snmp-5.2 overwrites /usr/lib/perl5/5.8.5/i686-linux/perllocal.pod with USE="perl" flag

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Jakub Moc (RETIRED) 2005-01-30 02:41:14 UTC]

Emerge fails with FEATURES="collision-protect", without collision-protect perllocal.pod is overwritten. :/

Reproducible: Always
Steps to Reproduce:
1. cd /usr/lib/perl5/5.8.5/i686-linux/
2. cp perllocal.pod perllocal.pod.orig
3. FEATURES="-collision-protect" USE="perl" emerge =net-snmp-5.2
4. diff -Nu perllocal.pod.orig perllocal.pod > perllocal.pod.diff

Actual Results:  
perllocal.pod overwritten after emerge

Expected Results:  
perllocal.pod should be appended, NOT overwritten!

Netmon,

Either append the info or find a way to use the perlmodules eclass (which appends the info ;) ). Let me know if you need help adapting it,

Well, I'm pretty sure I have the fix but cannot reproduce the collision.  Never seen something so odd:

$ equery belongs /usr/lib/perl5/5.8.5/i686-linux/perllocal.pod 
[ Searching for file(s) /usr/lib/perl5/5.8.5/i686-linux/perllocal.pod in *... ]
dev-util/subversion-1.1.1-r3 (/usr/lib/perl5/5.8.5/i686-linux/perllocal.pod)
net-analyzer/net-snmp-5.2 (/usr/lib/perl5/5.8.5/i686-linux/perllocal.pod)
net-im/gaim-1.1.1 (/usr/lib/perl5/5.8.5/i686-linux/perllocal.pod)

This is after merging with FEATURES="collision-protect".

So because of this, I am unable to test the solution.  I am posting the (hopefully) fixed ebuild here in hopes that you'll test it and let me know.

To test (I apologize if this is info you know already):
1) mkdir -p ~/overlay/net-analyzer
2) cp -R /usr/portage/net-analyzer/net-snmp ~/overlay/net-analyzer
3) export PORTDIR_OVERYLAY=~/overlay
4) save attached ebuild into ~/overlay/net-analyzer
5) ebuild ~/overlay/net-analyzer/net-snmp/net-snmp-5.2-r3.ebuild digest
6) FEATURES="collision-protect" emerge net-snmp

Thanks Aaron, but I

Thanks Aaron, but I´m afraid I cannot test the collision-protect fix either,  because now I have:

$ equery belongs /usr/lib/perl5/5.8.5/i686-linux/perllocal.pod
dev-perl/mod_perl-1.99.11 (/usr/lib/perl5/5.8.5/i686-linux/perllocal.pod)
net-analyzer/net-snmp-5.2 (/usr/lib/perl5/5.8.5/i686-linux/perllocal.pod)

So if it correctly appends perllocal.pod and does not overwrite it any more, I would mark this bug fixed as this was the main point of this bug. Perl devs have probably given up on getting collision-protect work with perl-related ebuilds - see Bug 71659. 

[Comment 6 Aaron Walker (RETIRED) 2005-02-02 03:02:15 UTC]

Fixed.  The ebuild now uses perl-module.eclass which, if the perllocal.pod file exists already, will install the pod into /usr/share/perl/gentoo-pods with a package specific file name.

[Comment 7 Michael Cummings (RETIRED) 2005-02-02 03:18:55 UTC]

(Realizing this is closed, but wanted to comment)

Out (my?) giving up with collision related bugs is related to circumstances where an ebuild of a module (preferably newer :) ) is attempting to replace a module that was provided in the core perl install. A good example of this was the Safe ebuild, which addressed security problems in the Safe module distributed with the old perl <=5.8.0 distributions - a case where you need to overwrite what's already provided. I asked Aaron not to let this one get lumped with that other bug because perllocal.pod overwrites is a different issue (just the same results).
