Uninstalling MacFuse on Lion

Last Updated on Samedi, 28 janvier 2012 09:15 Written by Henri Gomez Samedi, 28 janvier 2012 09:13

If you installed MacFuse on Lion (10.7) and tried to uninstall you may encountered the following error :

sudo /Library/Filesystems/fusefs.fs/Support/uninstall-macfuse-core.sh
MacFUSE Uninstaller: Can not find the Archive.bom for MacFUSE Core package.

Uninstaller didn’t check for Lion (uname -r reporting 11.x).
So fix is easy, just edit uninstaller script /Library/Filesystems/fusefs.fs/Support/uninstall-macfuse-core.sh and add 11*) in case next to 10*)

...

OS_RELEASE=`/usr/bin/uname -r`
case "$OS_RELEASE" in
  8*)
    log "Incorrect uninstall. Use the Tiger version please."
    exit 1
    ;;
  9*)
    PACKAGE_RECEIPT="$INSTALL_VOLUME/Library/Receipts/MacFUSE Core.pkg"
    OUTER_PACKAGE_RECEIPT="$INSTALL_VOLUME/Library/Receipts/MacFUSE.pkg"
    BOMFILE="$PACKAGE_RECEIPT/Contents/Archive.bom"
    ;;
  10*|11*)
     PACKAGE_RECEIPT=""
     BOMFILE="$INSTALL_VOLUME/var/db/receipts/com.google.macfuse.core.bom"

Building Universal Apache Tomcat Native Library on OS/X

Last Updated on Mercredi, 21 mars 2012 08:18 Written by Henri Gomez Mercredi, 13 juillet 2011 03:41

I recently notice that my Apache Tomcat running on OS/X 10.6.8 couldn’t use Apache Tomcat Native Library.

INFO: The APR based Apache Tomcat Native library which allows optimal
performance in production environments was not found on the
java.library.path:
.:/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java
Jul 13, 2011 11:02:30 AM org.apache.coyote.http11.Http11Protocol init

After digging around and with the help of ASFer Mladen Turk, I figure my previous build was stick to 64bits mode only and I switched my JVM to 32bits mode using -d32.

The fix was then easy, just had to rebuild tomcat-native and asking OS/X gcc to produce both 32/64 bits model library using the following CLFAGS/APXSLDFLAGS.

CFLAGS='-arch i386 -arch x86_64' APXSLDFLAGS='-arch i386-arch x86_64'

Here is a small script I’m using now to produce Apache Tomcat Native Library on OS/X.

curl http://mir2.ovh.net/ftp.apache.org/dist/tomcat/tomcat-connectors/native/1.1.23/source/tomcat-native-1.1.23-src.tar.gz -o tomcat-native-1.1.23-src.tar.gz
tar xvzf tomcat-native-1.1.23-src.tar.gz
cd tomcat-native-1.1.23-src/jni/native

CFLAGS='-arch i386 -arch x86_64' APXSLDFLAGS='-arch i386 -arch x86_64' ./configure --with-apr=/usr --with-ssl=/usr --with-java-home=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home --with-apxs=/usr/sbin/apxs
make clean
make

sudo cp .libs/libtcnative-1.0.1.23.dylib /usr/lib/java
sudo rm -f  /usr/lib/java/libtcnative-1.dylib
sudo ln -s /usr/lib/java/libtcnative-1.0.1.23.dylib /usr/lib/java/libtcnative-1.dylib

A note about Lion

If you get Java on Lion using the java command on terminal or via the Java Developer Package for Mac OS X 10.7, Java headers are not on the usual location and you could find them under /System/Library/Frameworks/JavaVM.framework/Versions/A/Headers

You should then update the configure command line like this :

CFLAGS='-arch i386 -arch x86_64' APXSLDFLAGS='-arch i386 -arch x86_64' ./configure --with-apr=/usr --with-apxs=/usr/sbin/apxs --with-ssl=/usr --with-java-home=/System/Library/Frameworks/JavaVM.framework/Versions/A/

Lion came with Xcode 4.1 and there is also an impact on linker side, libtcnative is now produced as libtcnative-1.0.dylib

Commands became so :

curl http://mir2.ovh.net/ftp.apache.org/dist//tomcat/tomcat-connectors/native/1.1.23/source/tomcat-native-1.1.23-src.tar.gz -o tomcat-native-1.1.23-src.tar.gz
tar xvzf tomcat-native-1.1.23-src.tar.gz
cd tomcat-native-1.1.23-src/jni/native

CFLAGS='-arch i386 -arch x86_64' APXSLDFLAGS='-arch i386 -arch x86_64' ./configure --with-apr=/usr --with-apxs=/usr/sbin/apxs --with-ssl=/usr --with-java-home=/System/Library/Frameworks/JavaVM.framework/Versions/A/
make clean
make

sudo cp .libs/libtcnative-1.0.dylib /usr/lib/java
sudo rm -f  /usr/lib/java/libtcnative-1.dylib
sudo ln -s /usr/lib/java/libtcnative-1.0.dylib /usr/lib/java/libtcnative-1.dylib

Apple JDK’s / OpenJDK’s – Core2Duo vs Core i7

Last Updated on Mercredi, 21 mars 2012 08:36 Written by Henri Gomez Lundi, 18 avril 2011 07:39

Previously I did benchmark of Apple VMs and OpenJDK 6 and I wanted to see how all of the JVMs available today on our Mac on two systems, an old Core2Duo and a newer Core i7. And also see how they perform 32 / 64 bits kernel mode.

So I redo full dacapo bench suite to include OpenJDK 6, and we have now 5 VMs (3 Java 6 and 2 Java 7) :

• Apple Java 1.6.0_22 – Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-314, mixed mode)
• Apple Java 1.6.0_24 – Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-348, mixed mode)
• OpenJDK 7 bsd-port – OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)
• OpenJDK 7 macosx-port – OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)
• OpenJDK 6 macports – OpenJDK 64-Bit Server VM (build 17.0-b16, mixed mode)

Results on MacBook Pro – Core2Duo 2.66Ghz – 32bits kernel

Results on iMac – Core i7 2.8Ghz – 64bits kernel

Conclusion

As seen if previous article, latest Apple JVM, 1.6.0-24 perform better than the old 1.6.0-22, and still behind OpenJDK 7 and even OpenJDK 6. OpenJDK 7 bsd-port is still faster (by a small factor) than OpenJDK 7 from macosx-port (built with LLVM), in both simple threaded (Core2Duo, 2 cores) and large threaded (i7 4 cores with hyperthreading).

This benchmark show how good is Intel Core i7 comparing to previous generation Intel Core2Duo, roughly twice as fast.
