rpmbuild change compression format
Solution 1
I was working with some RPM stuff today and accidentally stumbled upon the answer for ya!
Put these in your spec
file:
%define _source_payload w0.gzdio
%define _binary_payload w0.gzdio
That will still use gzip
but pass it -0
for a level, which should just store. On my RPM, it made it grow from 21MB to 76MB, so I'm pretty sure this is your answer!
BTW, I found that in one of the macro
files - you can also do bzdio
and any number from 0
to 9
to use bzip2
. This was on RHEL4; later versions of RPM seem to support more compression options; but again, for what you want, the above should be what you need.
Solution 2
Please check the file /usr/lib/rpm/macros in your build machine, (the file maybe diff in path), it has a total support list of compression methods there: e.g.:
329 # Compression type and level for source/binary package payloads.
330 # "w9.gzdio" gzip level 9 (default).
331 # "w9.bzdio" bzip2 level 9.
332 # "w7.xzdio" xz level 7, xz's default.
333 # "w7.lzdio" lzma-alone level 7, lzma's default
334 #
335 #%_source_payload w9.gzdio
336 #%_binary_payload w9.gzdio
so here just as Aaron said, you can set it here for universal, or set specifically for your proj. spec.
Solution 3
I ran into the same issue with Ant building a runnable Jar RPM with Spring Boot Loader complaining of this:
Caused by: java.lang.IllegalStateException: Unable to open nested entry 'BOOT-INF/lib/accessors-smart-1.2.jar'. It has been compressed and nested jar files must be stored without compression. Please check the mechanism used to create your executable jar file
My ant build task was like this:
<exec executable="rpmbuild" failonerror="true">
<env key="version" value="${fullversion}" />
<arg value="-ba" />
<arg value="--clean" />
<arg value="${specfile}" />
</exec>
My solution to build an RPM with a runnable JAR was to disable the repacking, setting the macro definitions on the spec file did not do it for me.
Adding this to the spec file was what worked for me:
#Disable jar unpacking
%define __jar_repack 0

Thanks to the previous posters for helping to focus in on the issue too.

I try to pack some map files for our geoserver in an internal rpm package. For the build part, this is just to copy the files. I think this works as expected. But it takes terribly long to pack those 20GB of images.
I've read that rpm internally compresses the data and that this can be done with several different compression algorithms. But, I don't have a clue which compression my rpm chooses and how I can influence this. I could not find any options for the rpmbuild command, nor for the specfile nor for the general rpm options I can list with
rpmbuild --showrc
I´m not very experienced with rpmbuild and specfiles, but after reading lots of man pages and tutorials on rpm.org I have no further ideas.
The specfile I use looks like:
%define debug_package %{nil} %global mapsversion 0.9 # If this is a snapshot, put the date here and uncomment #global snapshot_version 20100519 # This is the version in a form acceptable # an an RPM version string (i.e. no '-') # Hier werden die Makros definiert. %global rpmversion %(echo %{mapsversion} | tr '-' '_') %global pkgversion %{mapsversion}%{?snapshot_version:-SNAPSHOT} %global pkgname %{name} Name: geoserver-maps-part2 Version: %{rpmversion} Release: 1%{?dist} Summary: Swiss Maps for GeoServer Group: Application/ourApp License: Copyright (c) 2011 URL: http://doc.polyalert.local #Source0: %{name}-%{version}.tgz BuildArch: noarch BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n) Requires: geoserver %define mapshome /opt/geoserver/swisstopo %define mapssource /home/user/polyalert_env/geoserver/swisstopo %description Swiss Maps for GeoServer %prep %build /bin/true %install rm -rf $RPM_BUILD_ROOT mkdir -p $RPM_BUILD_ROOT%{mapshome} cp -a %{mapssource}/pk100 $RPM_BUILD_ROOT%{mapshome} %clean rm -rf $RPM_BUILD_ROOT %pre %post %preun %files %{mapshome}/pk100 %changelog * Tue Feb 14 2012 user - 1.0 - First version of specfile
I call rpmbuild like this:
rpmbuild -bb --define "_topdir $TOP_DIR" --define "_gpg_name ourkey" --define "_signature gpg" --sign $TOP_DIR/SPECS/$SPEC_FILE_NAME $RPM_BUILD_PARAMETER
Any suggestions?

Aaron D. Marasco about 12 yearsThe only compression I am aware of is
/usr/lib/rpm/brp-compress
will compress man pages. -
mkraemerx about 12 yearssince the RPMs are much much smaller than the provided input data, I'm pretty sure that all the data in there is compressed. I even figured out that zip archives (in my case jar files) contained in an RPM will be compressed again, so that the jar installed from the RPM is different compared to the input (even if its content is identical)..

Aaron D. Marasco about 12 yearsOK, I should have prefaced that with "the only user-controllable compression" then... ;)

mxmader over 9 yearswould like to see someone validate this on Fedora 20 or RHEL7.

Aaron D. Marasco over 9 yearsThose should support
xz
- see here. -
