Use immutable CRAN URLs
by Iñaki Ucar
Hi,
Currently, most of the R packages included in Fedora use the following
lines in the SPEC:
URL: https://cran.r-project.org/web/packages/%{packname}/
Source0: https://cran.r-project.org/src/contrib/%{packname}_%{version}.tar.gz
This URL format is not recommended by CRAN, but more importantly, the
Source0 format does not work anymore, as [1] noted, when a new version
is released. However, there is an immutable format available, as [2]
pointed out. So my proposal is to use always the following lines
instead:
URL: https://cran.r-project.org/package=%{packname}
Source0: %{url}&version=%{version}
which are both shorter and immutable, and I propose to add this to the
R packaging guidelines too.
If we agree on this, is there any easy way to request a system-wide
change like that to all existing packages?
Regards,

Attention Gmail users, please turn off HTML mail
by Dominik 'Rathann' Mierzejewski
Dear developers,
sorry for a slightly off-topic post, but I've noticed that a significant
number of posters is sending HTML e-mail to this list (not to mention
top-replying), which generates unnecessary network traffic. Some people
pay for every bit downloaded, so they're paying for the same information
twice, because the e-mails are sent with multipart/alternative format,
which contains BOTH text/plain and text/html. One thing I noticed those
senders have in common is that they use Gmail.
So, a plea to Gmail users: please stop sending HTML e-mail to Fedora
mailing lists.
Regards,
Dominik (who still reads e-mail in text mode in a terminal)

Blocking criteria proposal for F30+: Printing
by Stephen Gallagher
There was a bug[1] filed recently that indicated that printing was
broken on certain printers. As a result of that discussion, it became
apparent that there was no criteria for printing to work at all, which
seems like an oversight.
I discussed this briefly with Matthias Clasen this morning and he
agreed that this should be treated as blocking for Workstation.
I'd like to propose that we add the following criteria to Beta for Fedora 30+:
* Printing must work on at least one printer available to Fedora QA.
"Work" is defined as the output from the device matching a preview
shown on the GNOME print preview display. (Note that differences in
color reproduction are not considered "non-working".)
and this to Final for Fedora 30+:
* Printing must work on at least one printer using each of the
following drivers:
(I don't know which ones to specify here, but we ought to try to
figure out a cross-section that covers a large swath of our expected
user base).

Proposal: Abandon v8 package
by Tom Callaway
Background:
I made the original v8 Fedora package many moons ago, when I was more
optimistic about the possibility of separating the useful components
inside of chromium. Since that point, it has become clear that while v8
is useful software, the following facts are also true:
1. The v8 upstream is entirely disinterested in the concept of
maintaining any sort of ABI/API consistency between releases.
2. The v8 that is used in chromium is not necessarily compatible with
the upstream v8, as they have a history of picking and choosing code
changes (and even applying chromium specific changes locally).
3. Virtually all consumers of v8 (including chromium) take a git
checkout (not a specific one, just whatever they decided to code to) and
use that revision, often creating a local fork of v8 from that revision,
as they are either unwilling or unable to track v8 upstream.
4. Since v8 has no concept of a "stable" release that I can see, they
simply do security fixes to the master branch, which, combined with the
code changing violently, makes it very difficult to backport security fixes.
This means that other than plv8 (which is currently unable to build
against the current v8 package in Fedora), I do not see any consumers of
the Fedora v8 package (chromium has long since abandoned any possibility
of using it). It does contain a "d8" binary, which is a javascript CLI
debugger, but it is not clear to me that this is widely used, or that
the benefit of its inclusion in Fedora outweighs the pain of maintaining
this package.
Thus, I propose that the v8 package be abandoned/orphaned/taken to the
farm upstate to run and play with the other dogs.
If you disagree, or are crazy enough to want to take it over, speak now.
~tom
P.S. I'll still maintain v8-314 as best I can, since there are actually
users of that. The irony of that really ancient version being considered
stable (and thus, used by other software) as a result of Fedora sticking
on that version of v8 for so many releases is not lost on me.

F29 System Wide Change: OpenLDAP without Non-threaded Libraries
by Jan Kurik
= Proposed System Wide Change: OpenLDAP without Non-threaded Libraries =
https://fedoraproject.org/wiki/Changes/OpenLDAPwithoutNonthreadedLibraries
Owner(s):
* Matus Honek <mhonek at redhat dot com>
OpenLDAP will not ship non-threaded version of libldap. Instead,
libldap will be built with the same threading support as libldap_r.
== Detailed description ==
After this change the non-threaded version of libldap will not be
shipped any more. Instead, this library will rather be built the same
way as the threaded libldap_r. This has been previously discussed in
Bugzilla [https://bugzilla.redhat.com/show_bug.cgi?id=1370065] and
other distributions where this change already happened. Upstream still
supports non-threaded version of their library as it might be used on
processors where threads are not supported. However, when these two
versions happen to be loaded at the same time (as discussed about Curl
in the Bugzilla) symbol names overlap which may result in
unpredictable behaviour. Immediate solution would be to symlink
libldap to libldap_r, however SONAME of the library would be the same,
hence breaking dependencies of other packages. For that reason the
solution hereby proposed should be the most convenient one.
== Scope ==
* Proposal owners:
update SPEC file so that non-threaded libldap is replaced with threaded one.
* Other developers:
None. Issues should not occur.
* Release engineering:
[https://pagure.io/releng/issue/7253]
** List of deliverables:
N/A
* Policies and guidelines:
None.
* Trademark approval:
(not needed for this Change)

F29 System Wide Change: Remove Excessive Linking
by Jan Kurik
Note from Change Wrangler: This Change Proposal requires mass rebuild.
However, two weeks ago (June 19th), we have already passed the
deadline for Change proposals requiring mass rebuild. I will leave the
decision whether this Change proposal is accepted or not to RelEng and
FESCo teams.
= Proposed System Wide Change: Remove Excessive Linking =
https://fedoraproject.org/wiki/Changes/RemoveExcessiveLinking
Owner(s):
* Igor Gnatenko <ignatenkobrain at fedoraproject dot org>
* Neal Gompa <ngompa13 at gmail dot com>
Pass "--as-needed" flag the linker through default system-wide LDFLAGS.
== Detailed description ==
The flag ("--as-needed") tells the linker to link in the produced
binary only the libraries containing symbols actually used by the
binary itself. This binary can be either a final executale or another
library.
The use of the "--as-needed" flag allows the linker to avoid linking
extra libraries in a binary. This not only improves startup times (as
the loader does not have to load all the libraries for every step) but
might avoid the full initialization of big frameworks.
== Scope ==
* Proposal owners:
Add "-Wl,--as-needed" into RPM_LD_FLAGS (in redhat-rpm-config).
* Other developers:
Nothing should break, but immediate work-around would be to disable
this flag (will be provided in redhat-rpm-config) and fix real issue
later.
* Release engineering:
#7604 [https://pagure.io/releng/issue/7604] (mass rebuild is desired
after this change).
** List of deliverables:
N/A (not a System Wide Change)
* Policies and guidelines:
Add information how to turn it off (TODO link to FPC ticket).
* Trademark approval:
N/A (not needed for this Change)
