Description Jan Pokorný [poki] 2012-06-26 17:34:31 UTC

I've run into this in connection with bug 786372 (c12, c13).

1. install luci
2. start luci
3. remove luci

Now, you can see that paths from summary have been omitted.
Each seems to have the same files (ca. 540, 7 MiB) that
are probably translation strings cached as Python bytecode.

Suggestion:
Run rm -rf -- /var/lib/luci/var/pts /usr/lib*/luci/zope/var/pts
in "%preun -n luci" section.
The files are not present after prepare/build so they cannot be
captured naturally and enumerating them as %ghost does not seem to
be a good idea (unless the whole "pts" dir can be marked like this
with inheritance towards nested files).

Comment 1 RHEL Program Management 2012-06-26 17:48:16 UTC

This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux release.  Product Management has
requested further review of this request by Red Hat Engineering, for
potential inclusion in a Red Hat Enterprise Linux release for currently
deployed products.  This request is not yet committed for inclusion in
a release.

Comment 3 Jan Pokorný [poki] 2012-07-25 17:09:16 UTC

Test sequence I used to check the fix:

# # machine should be clean, ideally no luci ever installed
# ls -ld  /var/lib/luci/var/pts /usr/lib*/luci/zope/var/pts
ls: /var/lib/luci/var/pts: No such file or directory
ls: /usr/lib*/luci/zope/var/pts: No such file or directory

# # install package
# B='http://download.devel.redhat.com/brewroot/packages/'
# N=conga
# V=0.12.2
# R=57
# D=el5
# A=x86_64
# P=luci
# rpm -Uvh "${B}${N}/${V}/${R}.${D}/${A}/${P:=$N}-${V}-${R}.${D}.${A}.rpm"

# # start luci and see created *.mo files (message catalog cache)
# luci_admin init
# service luci start
# ls -l  /var/lib/luci/var/pts /usr/lib*/luci/zope/var/pts | less
# # ... plenty of files

# # remove luci and look again
# yum remove luci
# ls -l  /var/lib/luci/var/pts /usr/lib*/luci/zope/var/pts
ls: /var/lib/luci/var/pts: No such file or directory
ls: /usr/lib*/luci/zope/var/pts: No such file or directory
# # before, the files would stay as before uninstall process

This can be repeated in such a way that luci is not initialized/started,
hence the *.mo files at specified locations are not created at all.


Note: paths to remove are implemented using RPM macros that (as per
      errata's Rpmdiff) evaluate like this (nb. "lib*" above):
      - 386 ia64 ppc s390
          /var/lib/luci/var/pts
	  /usr/lib/luci/zope/var/pts
      - x86_64 ppc64 s390x:
          /var/lib/luci/var/pts
	  /usr/lib64/luci/zope/var/pts
