FastJar 0.99 ============================= FastJar is an attempt at creating a feature-for-feature copy of Sun's JDK's 'jar' command. Sun's jar (or Blackdown's for that matter) is written entirely in Java which makes it dog slow. Since FastJar is written in C, it can create the same .jar file as Sun's tool in a fraction of the time. History ======= FastJar was written by Brian Burns, toast@users.sourceforge.net. It was merged into gcc, and eventually merged out of gcc in 2006. This code is hosted on Savannah at http://savannah.nongnu.org/projects/fastjar/. Brian's original project is hosted on SourceForge, at http://fastjar.sf.net/. Motivation ========== "The reason I wrote fastjar is that building .jar files is a regular process of the build where I work. The way we have it setup, you have to re-create the .jar file everytime you want to test it out, which is about every 5 minutes when I'm busy coding. The .jar file wasn't -that- big, but it did take about 30 seconds to be made, and watching all the garbage collection messages was pretty irritating as well. I probably wasted a half-hour a day watching Sun's jar tool chug along. By writing the program in C, I spend much less time banging my head against the monitor waiting for the build to finish. Yay!" Requirements ============ FastJar has been tested on Solaris and Linux 2.2.x systems and nothing else. It should compile/run without any problems on either system, provided you have zlib installed. Platforms ========= i586-pc-minw32 -------------- In order to build FastJar without a Cygwin DLL dependency from Cygwin's shell, please set the flags CFLAGS=-mno-cygwin CPPFLAGS=-mno-cygwin CXXFLAGS=-mno-cygwin when calling the configure script. Bug Reports =========== Please submit bug reports to the fastjar bugtracker at http://savannah.nongnu.org/bugs/?group=fastjar. Compression will slow things down quite a bit. A 10MB jar file takes about 1 second on my machine without compression, and 9 seconds with it. If you want fastjar to be fast, use the -0 (zero, not O) flag to turn off compression. Supported flags: -------------------------- -c | create a new archive -v | verbose output -f | specify archive file name -m | specify existing manifest file -M | don't create manifest -0 | store only -C | change to dir -t | list contents -u | update exisiting archive -x | extract contents @FILE | treat contents of FILE as additonal options Unsupported flags: ---------------------------- -J | Pass an option to a JVM If you use the "unsupported" flags, nothing bad will happen, but then again nothing will happen at all. Unsupported features (in this release): --------------------------------------------- * full manifest support (?) Order or features for the future: -------------------------------------------- * full manifest support * filtering * dependency checking =========================================================================== http://savannah.nongnu.org/projects/fastjar/
