[Jazzlib-developers] licensing question

[Bosko M. <bo...@io...>]

Hi,
 
we are making a J2ME application that should be able to handle zip files
on mobile phone. We have migrated some of your classes to one of mobile
phone models and it seems to work fine. Intention is to sell the
application. Out client insist to have a exclusivity of 1 year to the
application which put us in situation not to be able to open the source
within this period. What shall we do? Is there any other possibility
that we satisfy our client and still to fit to your license?
 
Thanks for support.

RE: [Jazzlib-developers] UTF-8 error

[Christian S. <chr...@sc...>]

Hi Mike,

good news for you: The upcoming version 0.08 will solve this issue. =
There
are new constructors for the classes ZipFile etc. which allow you to =
specify
the character set. The character set originally used in most (if not all =
but
Sun's) ZIP implementations is "CP437" (the old PC character set). If you
specify this to the constructor, you will be able to read/write
international ZIP files.

As far as I know version 0.08 is scheduled for release in the next few
weeks. If you can't wait for this I could send you an inofficial diff
against 0.07 which I use for some months now to address the same issue. =
The
diff will be part of version 0.08, so you should throw it away once 0.08 =
is
released.

With best regards,
Christian Schlichtherle

[Jazzlib-developers] Higher performance for Adler32

[Thomas M. <hyp...@gm...>]

Hi, 

I have made some speed improvements for your Adler32 implementation.
In my test, the old code takes 1731 ms, my code takes 1061 ms.

public void update(byte[] buffer, int off, int len) {
    int s1 = checksum & 0xffff;
    int s2 = checksum >>> 16;
    while (off < len) {
        int max = Math.min(off + DEFER, off + len);
        while (off < max) {
            s1 = (buffer[off++] & 0xff) + s1;
            s2 += s1;
        }
        s1 %= BASE;
        s2 %= BASE;
    }
    checksum = (s2 << 16) | s1;
}

The important changes are:

- only increment one value (off++) in the main loop
  instead of (off++) and (n--)

- s1=...+s1 is a lot faster than s1=s1+...
  for some unknown reason (maybe the processor pipeline?)

DEFER is a new constant:

private final static int DEFER = 3850;

I calculated this value like this:

static {
    int i=0, a=BASE, b=a;
    for(;b>0;i++)
        b += (a += 255);
    System.out.println("max defer = " + (i-1));
}

I hope this helps,
Thomas

Re: [Jazzlib-developers] Why is DataFormatException and Checksum copied from the JDK?

Although jazzlib was once a separate project, it has now merged with the

classpath source tree, but the best place to discuss changes like this
is probably on the classpath mailing list.

[Jazzlib-developers] Patch to fix various bugs and provide enhancements

[Christian S. <chr...@sc...>]

Hi Jochen,

I have finally completed my bug fixes and enhancements and run a lot of
tests with several thousand files and some gigabytes of data in order to
ensure maximum stability. Please find enclosed the context diff on the
source tree as you have suggested - it is compressed using the package, of
course... ;-) (I have masqueraded it as a .jar file to force sourceforge's
mailing list daemon to accept it).

In summary I have fixed the following bugs:

+ ZIP file sizes up to 4GB are now supported - this is the maximum with the
ZIP32 file format.

+ Fixed the time conversion bug which made it impossible to use the last
modification time.

+ Implemented fail-fast-behaviour in the ZipFile class constructors for
compatibility with JDK

In addition, the following enhancements were made. More detail on those can
be found in the package description which I've added:

+ Added public constructors to ZipInputStream, ZipOutputStream and ZipFile
to specify other character sets for entry names and comments than UTF-8.
E.g. CP437 is most widely used on Windows.

+ Added protected constructors and methods to ZipInputStream,
ZipOutputStream and ZipFile to specify a different compression/decompression
engine or a different configuration than the defaults of this package. E.g.
on platforms where the JDK uses native methods for the
Inflater/Deflater/CRC32 classes it is very beneficial to use java.util.zip.*
instead of the classes in this package for increased performance
(compression performs better than factor two on Windows!).

+ Slight performance increases with ZipFile, ZipInputStream, ZipOutputStream
and ZipEntry.

Please have a look at my modifications and incorporate them into the
package.

With best regards,
Christian Schlichtherle

[Jazzlib-developers] Why is DataFormatException and Checksum copied from the JDK?

[Christian S. <chr...@sc...>]

Hi everyone,

 

I am about to redesign parts of the jazzlib package to allow the user to
select the particular implementation of the Inflater, Deflater and CRC32
class. This way a developer has the choice between optimum portability
provided by jazzlib or optimum performance provided by Sun JDK's native ZLIB
implementation. Now I have a question regarding this redesign:

 

Why is DataFormatException and Checksum provided? It seems to be copied from
the JDK, but it adds nothing to the original classes. I would like to get
rid of them in order to make my interface design easier and it would also
make the package a little bit leaner. I can't see why there should be
classes that add nothing to Sun's JDK implementation except that they would
allow

you to use it with a completely different implementation.

 

Any enlightenment welcome. :-)

 

With best regards,

Christian Schlichtherle

RE: [Jazzlib-developers] Patched latest version to fix various bugs

[Christian S. <chr...@sc...>]

Hi everyone,

OK, I will use my Knoppix/VMWare to create the diffs. Please bare with me
for a few days as I will need to do some code cleanups and this is not top
priority for the moment (I have modified the package to use Sun's native
Inflater/Deflater and CRC32 for performance reasons, so I need to reverse
this first).

Regarding the constructor: I think this is just what most people are
requesting from Sun since almost six (!) years - see Sun's bug database
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4244499.

Compatibility should not be an issue. The new constructors are a pure
extension while source and binary compatibility of older code is maintained.

Hope this helps.

Christian Schlichtherle

I'm not sure whether we are allowed to add new constructors.  Jazzlib is
used
in classpath as java.util.zip implementation, that should be compatible with
Sun's java class library. OTOH the current hard coded solution is certainly
suboptimal and an additional public constructor does not break binary
compatibility.

Yes it sounds interesting

The best way is to create a diff and send it to this list, or add it
to the patch
tracker. The patch needs to be applied to classpath, too, so it doesn't make
sense if you get write access to the CVS without write access to classpath
CVS.

If you work on a checked out CVS repository, you can get easily get a diff.
E.g. if you use the cvs command line tool that comes with cygwin, you can
just do "cvs diff -u" in the repository.  I think the graphical cvs tools
also 
have something that does this.  Please use unified (-u) diffs, as they are
the
best to read.

You can also use the diff utility (from diffutils) to compare your modified 
directory with an original one: "diff -ur jazzlib-orig jazzlib-modified"

If your contribution is large, we need you to assign copyrights to FSF due 
to legal reasons.  This is because the patches should go to GNU classpath,
too.

Regards,
  Jochen

Yes it sounds interesting

The best way is to create a diff and send it to this list, or add it
to the patch
tracker. The patch needs to be applied to classpath, too, so it doesn't make
sense if you get write access to the CVS without write access to classpath
CVS.

If you work on a checked out CVS repository, you can get easily get a diff.
E.g. if you use the cvs command line tool that comes with cygwin, you can
just do "cvs diff -u" in the repository.  I think the graphical cvs tools also 
have something that does this.  Please use unified (-u) diffs, as they are the
best to read.

You can also use the diff utility (from diffutils) to compare your modified 
directory with an original one: "diff -ur jazzlib-orig jazzlib-modified"

If your contribution is large, we need you to assign copyrights to FSF due 
to legal reasons.  This is because the patches should go to GNU classpath,
too.

[Jazzlib-developers] Patched latest version to fix various bugs

[Christian S. <chr...@sc...>]

Hi everyone,

 

I've downloaded the latest version of jazzlib in order to use it with my
file synchronization software TrueMirror, which shall be released soon.

 

After zipping and unzipping some Gigabytes of data with 15.000 files, I have
modified the sources to support/fix the following:

 

+ Added new constructors to support arbitrary character sets for entry names
and comments for international ZIP files. As an example, CP437 may be used
which seems to be most widely used.

+ Fixed bug in date/time conversion.

+ Enabled support for ZIP files up to 4 GB. The current version only
supports 2GB due to erratic signed int usage.

 

If this sounds interesting, then I would be more than happy to provide my
modified sources for inclusion in the standard distribution.

 

Now the bad news: I never worked with CVS! So how could I contribute? I am
working with Netbeans 4.0 and noticed that it has some support for CVS, but
I am not sure if I need additional software and where to start. If someone
could prod me into a short tutorial I'ld be more than delighted. :-)

 

With best regards,

Christian Schlichtherle

RE: [Jazzlib-developers] another license question

[Andrew F. <And...@ar...>]

hi Mark,

 i've updated the wiki as requested
=09
http://developer.classpath.org/licensing/ProposedFaqs?action=3Dshow

 I think there is ambiguity as to what 'merging' jars means when
non-trivial manifest files are present but i didn't want to clutter the
page (and am not that clued up on what exactly goes in manifest files
offhand)

My feeling is that merging the jar with others is within the spirit of
the original license as it is only a different packaging method?

thanks,
Andrew

Jazzlib is a part of GNU Classpath for which we are looking to clarify
the license text to make these kind of questions easier to answer. Could
you add the above as a proposed FAQ to the licensing wiki?
http://www.gnu.org/licensing/classpath/

Thanks,

[Jazzlib-developers] another license question

[Andrew F. <And...@ar...>]

hi,

 does anyone know whether merging the jazzlib jar with your own classes
to produce one fat jar is allowed by the license?

the only motivation for this is to reduce classloading time when
launching from CD (there are lots of jars, one of which is jazzlib, so
ideally i'd like to create one jar file and have that on cd)

on slow cd drives this can make a real difference!

thanks,
Andrew
ps. jazzlib has really helped get round the horribly slow index reading

Yes, since jazzlib is part of GNU Classpath (distributed separately),
which is an official GNU project of the FSF that is the best way. I

The FSF agreed to clarify the text of the exception statement we are
currently using. They setup a wiki to get input
http://www.fsf.org/licensing/classpath
There is a special page for giving input on different scenarios in which
(parts of) GNU Classpath are used to create larger works. Please add
this scenarios there.

You can find more information about the license and the rationale behind it
by searching the classpath archives.

http://lists.gnu.org/archive/cgi-bin/namazu.cgi?query=3Dlicense&submit=3DSe=
arch%21&idxname=3Dclasspath&max=3D10&result=3Dnormal&sort=3Dscore

See also the "Unofficial GNU Classpath License Rationale"

The switch was done vice versa from LGPL to this license.  The main differe=
nce
is that the license allows static linking.  This was needed by the gcj-deve=
lopers
(the GNU java compiler), which allows to produce static executables.   The =
change
was done, when classpath and gcj merged their code base.

Hope this helps to clarify this.

  Jochen

I'm not 100% sure what executable means here, but it is clear that you are producing a
"combined work" because you are linking to the jazzlib library.

 
> 2) IN the given license, what is meant by "independent module" ?

"An independent module is a module which is not derived from or based on this library"

So if you didn't use any of the jazzlib source code in your own code, I would argue it is
independent.

I don't know what the plans are for future Classpath licenses.

It sounds like you can use it as you describe above without changing hte license of your
program.

Again, you won't have to put your program under the GPL. You won't have to release your
source code.

[Jazzlib-developers] question about your license

[Daniel B. <Dan...@gm...>]

Hi,

first of all : thanks for your quick answer.
But because I don´t really understand this license, I have to ask you again.


1) In the given license, what is meant by "produce an executable" ? We are
programming java, so we can´t really create an executable.

2) IN the given license, what is meant by "independent module" ?

3) Do you plan to switch to the LGPL ? These licenses quite sound the same
to me.

We are programming some sort of email - processing program using your
library to process zip Files.

We intend to sell this program. We don´t create derived classes, we just use
your library by adding it to our classpath.
So, one more questions :

4) When exactly would we have to do if we intended to put our program under
the GPL by using your library ? 

Once again, thanks for your answer.
I just ask all these questions again, because we can´t afford a lawyer to
help us with this stuff :)

With kind regards

Daniel Breitner

Re: [Jazzlib-developers] question about your license

[<je...@pi...>]

The exception (described at http://www.gnu.org/software/classpath/license.html) allows you
to use jazzlib in your program without any implications for the license of your program.
