[gentoo-java] migration-overlay entering main tree

Over this past weekend, I put migration-overlay into the main tree:

Everything related to it is currently sitting in package.mask:

To try it out, add the above entry to /etc/portage/package.unmask.

If you were already using migration-overlay, you'll want to remove it
from PORTDIR_OVERLAY.

If you weren't, you'll need to follow the instructions at:
http://www.gentoo.org/proj/en/java/java-upgrade.xml

I would like to unmask these packages in the next few days. At that
point, I'd like to 'officially' announce it, as in put it on the front
page, send to -announce, etc.

Thanks for doing this, and for the E-mail update.  I've been noticing
the changes in migration-overlay this weekend. :-)

FYI:  For some reason (at least in my mail client) some extra chars
(like this: "> ") appear at the beginning of a few lines in your list
(below).  Folks should be aware that certain packages won't be visible
unless they remove these extra characters from the front of the
applicable lines.

The corrected list should appear something like this:

Another note:  You list sun-jdk-1.5.0.07 and my system does have it
installed (it appeared in migration-overlay a week or two ago).
However, the ebuild appears to have been deleted from the overlay and it
is NOT anywhere in the main Portage tree.  Unless you still need to add
it something must have gone wrong.  Just FYI...

Sounds good to me.  They seem to be working well so my vote is "the
sooner the better".

Thanks again for all of the hard work!

Yeah, I noticed that after sending it. Of course, you can look at
/usr/portage/profiles/package.mask, and pull the appropriate entries
from there.

There's a lag between when something gets committed to CVS, and when it
propogates to all the rsync mirrors.

Indeed. I mostly want to make sure everything got into place fine. So...
to help with this, I ask everyone try re-merging the packages formally
in the overlay (now in the package.mask), to make sure all the distfiles
and packages are there, and that the system continues to work.

Missing ebuilds in the tree (checked also
http://sources.gentoo.org/viewcvs.py/gentoo-x86/dev-java/ and not there
either, so I guess not rsync lag problem?)

dev-java/ant-tasks-1.6.5-r2
ibm-jdk-bin 1.4.2.05 and 1.5.0.02 (were my bumps bad?) - the existing
1.5.0-r11 has broken digest because IBM changed the files (bug 130533)

Missing distfile/wrong version? of java-config-wrapper (bug 138015)

I think many people get the whole migration stuff pulled just because
they used java 1.5 faq to have 1.5 VM with generation-1. It tells you to
# echo "=dev-java/sun-jdk-1.5*" >> /etc/portage/package.unmask
which overrides your package.mask for 1.5.0.07 which then tries to pull
everything... Well at least more testers for us :)

Whoops. Was sitting uncommitted in my tree. Should be fixed in CVS, and
will take a bit to propogate.

Fixed in CVS too.

That's what you get for using package.mask stuff without using precise
verion atoms :-D

Fixed as well. It seems that at some point, the patch was gzipped living
in filss/. This generally a bad thing (tm), and was fixed at some point
_after_ it was pulled into axxo-overlay way back when, so it was still
pointing to the gzipped version.

By the way, will you be mergeing migration-packages to the main tree too ?

Not immediately, and not at once. migration-packages is essentially the
same as java-experimental, except it is using the new eclasses and
tools. So, once we're over the initial bump of the merge, we will resume
regular version bumps / bug fixing / introducing new packages.

Just some cosmetic stuff I've run into, not deserves a bug (or even 3
bugs) I guess :)

- java-check-environment says "Please refer to
https://projects.gentooexperimental.org/expj/wiki/ for details" - this
should point to http://www.gentoo.org/proj/en/java/java-upgrade.xml now
I think?

- as we talked on IRC, java-config-1 -s should now refuse to set user
vm, and probably all JRE's could drop gen-1 env because they can't be
used for building anyway

- when user runs e.g. javac with a JRE, he gets:

javac
Want too run
/home/caster/.gentoo/java-config-2/current-user-vm//{,jre}/bin/javac but
it does not exist or is not executable
Broken vm install

Maybe make this more user friendly? Fix typo "want too" and change to
something like "Broken VM installation or you are trying to use JDK
functionality (e.g. compiling) from JRE."

I think it's probably a good thing, but I'm not fluent in python enough
to patch it up.

Re: [gentoo-java] migration-overlay entering main tree

[Wiktor Wandachowicz]

Here are my experiences with Java upgrade on a second machine, done step
after step like in the Java Upgrade Guide. Sorry for the length, but I wanted
to be as specific as possible.

After unmasking packages, I removed sun-jdk-1.4*, sun-jdk-1.5* and java-config.
Then I emerged java-config-1* and java-config-2*. All was fine. After emerging
the first JVM I've noticed an error:

# emerge -av =sun-jdk-1.4*
...
!!! ERROR: The active vm could not be found
 *  After installing sun-jdk-1.4.2.12 this
 *  was set as the default JVM to run.
 * No valid generation-1 system-vm set, setting to sun-jdk-1.4.2.12

Nothing serious that a simple "/usr/sbin/env-update && source /etc/profile"
couldn't resolve. And only after two last commands the "java-check-environment"
was able to report success with generation_1_system_vm. I double checked
via "java-config-1 -L" and "java-config-2 -L" that only one JVM was present at
the moment. All was fine.

Then I emerged sun-jdk-1.5 and run the "java-1.5-fixer". Now it became
interesting, because the tool reported *twice* missing packages:

# java-1.5-fixer
 * You need to emerge portage-utils.
# emerge -av portage-utils
 * You need to emerge >=javatoolkit-0.1.6
# emerge -av javatoolkit
# java-1.5-fixer

Well, that's was a little surprise, because the Guide didn't mention these
two packages at all. Not actually confusing for me, but the Guide could at
least explain that need. Less fluent Gentooers can be surprised and
completely unnecessary topics on the forums may arise.

Another intriguing thing was the output while emerging javatoolkit. I've seen:
...
>>> /usr/share/doc/javatoolkit-9.9.9/
>>> /usr/share/doc/javatoolkit-9.9.9/sun-fetch/
>>> /usr/share/doc/javatoolkit-9.9.9/sun-fetch/AUTHORS

even though I installed javatoolkit-0.1.9 and not -0.9.9

Last problematic thing I've noticed was the number and order of
packages java-fixer was about to repair:

# java-1.5-fixer
 * Generating a list of jars which ant uses ...                          [ ok ]

=sys-libs/db-4.3.29

I turned out that even though hsqldb was listed three times, it still
depended on servletapi, which was scheduled fourth. So it broke:

I needed to remerge servletapi manually and restart java-1.5-fixer. Which,
of course, built hsqldb three times :-( Which was, of course, unnecessary.
How about at least making the packages that java-1.5-fixer is going to fix
unique? And how about figuring a better ordering of packages?

After all the above I think I've finally migrated my machine to Generation-2.
Whoopiee!

In general all was fun and problems were minor IMHO. But migration was
not automatic, like some users would like it to see. Maybe some things
coul dbe improved before stabilization?

Granted, the messages could be improved a bit. It's not mentioned in the
guide, because a) java-1.5-fixer may not be required and b) it's pretty
straight forward to emerge these if you don't have them.

Freaky. I can't say that I've seen that before.

If you let it keep running, it would have eventually gotten to
servletapi, rebuilt that successfully, then retried hsqldb. As for why
it's listed 3 times, I'm not quite sure. It _should_ be filtering
duplicates as I recall.

I don't believe it would be possible to have a migration that was
totally automated, to be honest. There are a number of pitfalls as is,
like not having all the new Java  packages unmasked and keyworded, user
used 1.5 at some point and needs to recompile everything with 1.4, etc.

Re: [gentoo-java] migration-overlay entering main tree

[Wiktor Wandachowicz]

Well, I unmasked the packages and tried to do the dumbest thing
under the Sun (pun intended): upgrade the system WITHOUT reading
the migration guide ;). I believe this is something that quite a bit of
[careless] users would do. I expected problems, but in the end I've
found none (!)

And I really like the new java-config working in the "old" fashion too :)
It hides the java-config-1 / java-config-2 complexity from the less
knowledgeable users.

Great job, guys!

Would you like to merge these packages? [Yes/No]

... all went well ...

So, the dumbest case seems to be covered. I hope this helps :)

Now I'm looking into setting a sun-jdk-1.4.2 on amd64 as the system
and/or build VM. I *know* it's not meant to be used as a Java plugin for
64-bit firefox, but it could be used for 32-bit firefox-bin. And with multilib
profile in place and emul-* libraries it should work without problems.
I will send an update on this case soon.

Cheers,
Wiktor

Ok, so here's the update.

I have firefox-bin installed on amd64 architecture. It works, but uses the
Blackdown JDK 1.4.2 in form of emul-linux-x86-java-1.4.2.03-r1 package.
This package puts a link to its Java plugin for 32-bit Firefox in
/usr/lib32/nsbrowser/plugins directory.

As I already mentioned on the Forums [1] it's possible to run 32-bit
Firefox in 64-bit environment with 32-bit Java plug-in from sun-jdk-1.4.2.

Here's what I did:

echo "=dev-java/sun-jdk-1.4.2* doc jce -nsplugin" >> /etc/portage/package.use
echo "=app-emulation/emul-linux-x86-java-1.4* -nsplugin" >>
/etc/portage/package.use
emerge -av emul-linux-x86  # to get rid of Blackdown Java plugin
emerge -av =sun-jdk-1.4*
mkdir -p /usr/lib32/nsbrowser/plugins
cd /usr/lib32/nsbrowser/plugins
ln -s /opt/sun-jdk-1.4.2.12/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

After restarting firefox-bin in its about:config I was happy to see:

  Java(TM) Plug-in 1.4.2_12-b03

instead of Blackdown's. So I did it again ;)

Now, the questions. Could it be possible to support 32-bit sun-jdk in amd64
environment for 32-bit firefox-bin (only)? In a way similar to the
emul-linux-x86
package does? I know how to handle that situation manually, but it's not the
optimal solution (or did I miss something?)

Cheers,
Wiktor
