#8773 — Trying to free f2c

Hi,

since I'm really bored by the non-free f2c package which throws a
certain number of packages into contrib I checked again what we could
do.  It seems the main reason why f2c is non-free is that it includes
goto_trans (non-commercial use, no fee).  The code describes itself
as

JAVAB -- A prototype bytecode parallelization tool.
    This tool can be used to exploit loop parallelism directly at
    *bytecode-level* using the multi-threading mechanism of the JVM.
    In addition, the tool provides some elementary support for the
    automatic *detection* of implicit loop parallelism.

(see CVS[1]).  The code that translates fortran code into java is GPLed
and as far as I can see we need this functionality.  However, I can not
believe that these days Java compilers might need a tool that was
written in 2008 and has not changed like this to fullfill an
optimisation process that might be perfectly usable by a lot of
applications.

So my question is:  Do we possibly rely here on a non-free tool that
is really not needed and we could simply drop it?

Kind regards

     Andreas.

I got a quick look and you might be right, the goto_trans stuff seems
optional. What happens if you don't install javab in the f2j package?

Hi Emmanuel,

I did a quick test with a local build.  I can easily build
libnetlib-java_0.9.3 fith f2c without the javab executable.  I have no
idea how to do proper performance tests, thought.  I have no idea
whether javab is used in the build process at all - may be I should
do some investigation of access timestamp.

In case your insight says that javab is not needed I'd consider the
following procedure:

   1. I create a tarball without non-free code
      (there is one other remaining file but PrintfFormat.java[1]
       does not sound as if could not be replaced by something else)
   2. Move this to pkg-java Git and create a package from this.

May be somebody can give hints according to performance tests to compare
libnetlib-java build with and without javab.

What do you think?

Kind regards

     Andreas.

I implemented the plan in pkg-java git.  The only problem to build the
package is the now missing PrintfFormat.java[1] which now leads to

/usr/bin/javac -source 1.2 -target 1.2 -d obj org/j_paine/formatter/*.java
warning: [options] bootstrap class path not set in conjunction with -source 1.2
org/j_paine/formatter/Formatter.java:556: error: cannot find symbol
      s = new PrintfFormat(fmtstr).sprintf(o);
              ^

  location: class FormatI

  location: class FormatE

Makefile:11: recipe for target 'f2jutil.jar' failed


I wonder whether some Java programmer could provide some simple
replacement.  If this would be provided I'd upload to experimental first
and let follow the whole chain of dependencies as well to experimental.
The final consumer of all the mess will be the beast-mcmc package and
this one has performance tests that we could run to get a final decision.

Kind regards

         Andreas.

Sun did that for us 11 years ago in Java 5 ;) Try this replacement:

    s = String.format(fmtstr, o);

What do I need to import to access this?

Sorry for the beginner question but Google points me to

   package com.javacodegeeks.core.string;

which seems wrong ...

I guess nothing at all, it's currently included [0] in java.lang package
by default.

Forget this question - I've found

--- a/util/Makefile
+++ b/util/Makefile
@@ -5,7 +5,7 @@ JAR=jar

 UTIL_JAR=f2jutil.jar

-VER_TARGET=1.2
+VER_TARGET=1.5

 $(UTIL_JAR):
        mkdir -p $(OUTDIR)

as solution.

Sorry for the noise

      Andreas.
