semanage and RHPL

semanage and RHPL

[Stephen Bennett]

Hi,

After encountering some problems with modular policy in the released
toolchain packages, it was suggested to me that I try the svn
toolchain. I did this, and found that semanage and genhomedircon both
traceback when run, failing to import functions from rhpl.translate.
This package doesn't appear to be available in Gentoo's repository, and
a quick bit of searching suggests that it's a Red Hat-specific library.
Is this dependency intentional or desirable? If yes, where can we get
the sources to package it for other distros?

Thanks in advance for any input.

rhpl.translate is described as a "persistent global gettext service for
python programs".  Not sure why that is RH specific.

The source is available from the Fedora CVS tree
(http://cvs.fedora.redhat.com) as well as in the SRPMS.  You can grab it
via:
curl -O -R -S --fail --show-error http://cvs.fedora.redhat.com/repo/dist/rhpl/rhpl-0.187.tar.gz/7979e7677a5cb32c06d176052403c707/rhpl-0.187.tar.gz

Having investigated this some more and discussed it on IRC, it seems
that rhpl is only being used for one function (_), which it seems can
be replaced by Python's standard gettext interface. A patch to do this
is attached, tested with LC_* both unset and set to en_GB. semanage and
genhomedircon are known to work in these situations; the changes to the
other scripts are identical so they ought to work as well. Please
comment.
