upgrading RH 9 system->Fedora with iso files and apt only
by Didier Casse
I have the yarrow's iso files on my HD in a RH9 system. Let's say I want
to upgrade selected packages using an "apt-get install" pointing to my
iso-mounted files, how do I do it?
i.e I mount the iso into some /mnt/yarrow1, /mnt/yarrow 2 etc..
Then what is the complete procedure to make my apt look into my own HD to
upgrade packages. Can anybody redirect me to the correct
resource or some literature hanging on the web? Thanks.
Assume also that I do not wish to burn CDs! I do not want to use
apt-cdrom. Thanks.
With kind regards,
Didier.

pdftk retired?
by Michael J Gruber
I just git a "broken dependencies" notice for a package that I maintain.
The reason is that "pdftk" got retired just the other day.
I may have missed a corresponding post on fedora-devel, but I think a
heads up notice to maintainers of depending packages may be in order
before you retire a package, as a general idea.
You see, unretiring a package is so much more work than changing
maintainership.
As for pdftk: I see 2 failed builds for version 1.45 and none for the
current version 2.02 (which probably breaks the api anyways). What are
the plans? Retire pdftk completely? Start fresh with pdftk2?
pdflabs, the maker of pdftk, provide binary as well as source rpms for
pdftk 2.02, by the way. I might even look into packaging it but don't
want to duplicate any existing efforts.

Intel's Clear Linux optimizations
by František Zatloukal
Hi,
Phoronix recently release article[1] about Intel's Clear Linux with some
cool graphs showing nice performance gain compared to Xubuntu.
I didn't have time to dig in and look how it's performing against Fedora,
but I'd assume Fedora can be compared to Xubuntu in terms of compiler
settings.
I think i'll be interesting to look into it and find out if Fedora can't
tweak compiler settings (eg use LTO for critical things like Mesa, Kernel,
...). I think it could be interesting fo Fedora users to have this enabled
if there are not any disadvantages other than compile time, compile memory
usage and so on.
What do you think?

Python3 will be in next major RHEL release, please adjust %if
statements accordingly
by Troy Dawson
Hello,
Python3 will be in the next major RHEL release. I don't mean RHEL
7.6, but with numbers higher than 7.
There are many, many packages with something like the following
if 0%{?fedora}
%define with_python3 1
%endif
If you have something like that, please change it to something like this.
if 0%{?fedora} || 0%{?rhel} > 7
%define with_python3 1
%endif
Thank You

kcov: code coverage for programs and python/shell scripts
by Dridi Boukelmoune
Greetings developers,
I just submitted a review request [1] for kcov [2] that I recently
discovered. It has no relation to Linux's kcov and is more akin to
lcov, except that all it needs is a binary with DWARF debuginfo
instead of requiring compile-time instrumentation.
I came across kcov when I was looking for a way to measure code
coverage in a Rust project and I'm impressed. It supposedly has a low
overhead, but so far I've been monitoring small single-threaded
programs so I can't really tell. I haven't tested python and shell
support, although I have cases where it would be relevant, but I don't
have time yet.
The package itself is simple, but it bundles javascript and doesn't
build on all main platforms so I may have to be granted an exception
from some group starting with an F. Been busy lately, I'm a little
behind on anything Fedora. If that's the case, please RTFM me a link
to the wiki, and if you want to take the review I'll gladly take one
in return.
Cheers,
Dridi

[RFC] Replace glibc's libcrypt with libxcrypt for Fedora 29/30
by Björn 'besser82' Esser
Hello everyone,
since there has been some discussion in the last time about removing
libcrypt from glibc in some time [1,2,3,4] and splitting it out into a
separate project which can evolve quicker, I'd like to hear your
oppinion about replacing glibc's libcrypt with libxcrypt [5] for Fedora
29 (or 30).
libxcrypt will be fully binary compatible with software linked against
glibc's libcrypt and does not require any rebuilds. However, the
converse is not true: programs linked against libxcrypt will not work
with glibc's libcrypt. It comes with a set of extended interfaces
pioneered by Openwall Linux, crypt_rn, crypt_ra, crypt_gensalt,
crypt_gensalt_rn, and crypt_gensalt_ra. Also, programs that use
certain legacy APIs supplied by glibc's libcrypt (encrypt, encrypt_r,
setkey, setkey_r, and fcrypt) cannot be compiled against libxcrypt.
The crypt and gensalt functions are supporting all (except for Crypt16,
which was used on Ultrix and Tru64, only) widely used password hashing
algorithms [6], which before were specific to just some operating
system's implementations of libcrypt [7].
There are preperations to add password hashing with PBKDF2 using HMAC-
SHA3-512 to libxcrypt as well.
Anyways, before this can happen, there is still some work to be done
with libxcrypt, like adding a FIPS mode or FIPS compliance in a
different way.
Cheers,
Björn

Orphaning ofono
by Rex Dieter
I will be orphaning the ofono package today. I'd primarily packaged it with
the the intention that it may become a new dependency of pulseaudio (which
never happened), and I've not been able to give it the time it needs.
Recently updated to latest 1.22 release which fixed a long-standing FTBFS
issue, so at least it is in good shape for anyone interested in picking it
up.
