Poking through an rpm that
I “traffic” quite a bit today and saw a particularly nasty bit of
code I'd put together. This is a pretty long thread, so I'll spare
everyone loading down the main page with it. Suffice it to say, I'd
like to immortalize my mistake in the website so I never do this
again. If anyones interested I can go into RPM kung-foo like this in
more detail later.
%triggerin -- j2sdk
# check /usr/lib/jvm
if [ -f
/usr/lib/jvm/java*/bin/java ]; then
chpax -emsrpx
/usr/lib/jvm/java*/bin/java
fi
if [ -f
/usr/lib/jvm/java*/bin/javac ]; then
chpax -emsrpx
/usr/lib/jvm/java*/bin/javac
fi
if [ -f
/usr/lib/jvm/java*/jre/bin/java ]; then
chpax -emsrpx
/usr/lib/jvm/java*/jre/bin/java
fi
if [ -f
/usr/lib/jvm/java*/jre/bin/javac ]; then
chpax -emsrpx
/usr/lib/jvm/java*/jre/bin/javac
fi
# check /usr/java
if [ -f
/usr/java/j2sdk*/bin/java ]; then
chpax -emsrpx
/usr/java/j2sdk*/bin/java
fi
if [ -f
/usr/java/j2sdk*/bin/javac ]; then
chpax -emsrpx
/usr/java/j2sdk*/bin/javac
fi
# because they hide them
in lib
if [ -f
/usr/lib/jvm/java*/bin/java ]; then
chpax -emsrpx
/usr/lib/jvm/java*/bin/java
fi
if [ -f
/usr/lib/jvm/java*/bin/javac ]; then
chpax -emsrpx
/usr/lib/jvm/java*/bin/javac
fi
# generic catch all
if [ -d /usr/java ]; then
find /usr/java -name
java -type f -exec chpax -emsrpx {} \;
find /usr/java -name
javac -type f -exec chpax -emsrpx {} \;
fi
# generic catch all for
/usr/lib/jvm
if [ -d /usr/lib/jvm ];
then
find /usr/lib/jvm -name
java -type f -exec chpax -emsrpx {} \;
find /usr/lib/jvm -name
javac -type f -exec chpax -emsrpx {} \;
fi
I then had duplicated this
trigger 3 more times (I'll spare you), for java-1.4.2-sun,
java-1.4.2-gcj-compat, and java-1.4.2-sun-devel. So all told about
200 lines to fix some PaX related flags with java. A clever soul
will note that even I had figured out a better way to do it at the
end when I wrote it. Except for some reason I just kept doing the
same stupid routine 3 more times. Allow me to demonstrate by showing
you what it looks like now:
# Java
%triggerin -- j2sdk
java-1.4.2-sun java-1.4.2-gcj-compat java-1.4.2-sun-devel
killall -9 java >/dev/null
2>&1
if [ -d /usr/java ]; then
find /usr/java -name
java -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1
find /usr/java -name
javac -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1
fi
if [ -d /usr/lib/jvm ];
then
find /usr/lib/jvm -name
java -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1
find /usr/lib/jvm -name
javac -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1
fi
For anyone thats still
bored enough to read down to the end of this thread, this is an
example of an RPM trigger. The above detects (in one line!) when the
packages j2sdk java-1.4.2-sun java-1.4.2-gcj-compa and
java-1.4.2-sun-devel are installed/updated, and runs the following
routine against them. Triggers make me happy.
You know the best part of
all this was that the trigger right after this was a multi-package
trigger that was the right way to do it all along. Staring at me....

Nice one!

Mike tells me to whip up an oinkmaster rpm, so I did what I normally do, which is to look to see if theres one out there alread. Google for "oinkmaster src.rpm" and wham, 7th hit on the page is my own site.
