[Clirr-user] Any release of Clirr planned in the future?

[Matt G. <Mat...@mo...>]

Hi,

It looks like there's not been any traffic on this mailgroup for a long time
but I figured it was worth a try given I can see some checkins in May 2009.
Is there any plan to release a 0.7.0 release of clirr? We hit this issue in
our CI builds
http://sourceforge.net/tracker/?func=detail&aid=1710771&group_id=89627&atid=590799and
I've just downloaded a snapshot and its fixed in the current code in
trunk. Given that I saw some checkins from May this year I was wondering if
that a sign of a possible new release on the horizon?

Thanks,
Matt

As requested, here is a preview snapshot release (alpha quality) for 
those users who are willing to test the current development status, but 
are unable to build from CVS.

Here is the direct download link:
http://downloads.sourceforge.net/clirr/clirr-0.7-SNAPSHOT-20070519.zip

The upcoming Clirr Version 0.7 will switch bytecode processing from BCEL 
to ASM. This has already been implemented in this snapshot, but it's 
quite a drastic implementation change and surely some bugs need to be 
ironed out before the final 0.7 release. Feedback is extremely welcome!

Note that unlike normal releases this code has not received a lot of QA 
prior to releasing it, hence the SNAPSHOT status. This release should 
not be used in production!!

Outstanding issues before release 0.7:
* Change license from LGPL to ASL2 throughout the code
* fix bugs reported by users of this snapshot
* QA: Test against well known library code bases, like log4j, hibernate, 
spring, jakarta-commons-*, and compare results with Clirr 0.6
* QA: Test in different JDK versions, 1.4 - 1.6

Cheers,
Lars

What I meant is I only use Maven for Clirr and for no other project.

As for your "you better should" comment in the other email: Well, I'm in 
a love-hate relationship with Maven. I love that it (1) allows you to 
build simple one-source-tree-one-jar projects declaratively, and that it 
(2) downloads dependencies automatically. I hate all other aspects of 
Maven :-)

As an example, try to have a look at the maven.xml in the clirr toplevel 
module [1]. I'm sure this is not the "maven way", but I couldn't find 
any other way to build the release binaries that contain everything in 
one download, and I spent way too much time wrestling with this stuff - 
much longer than it would have taken me to write a build.xml for Ant.

Other points: Unit test execution takes forever and doesn't report the 
failing test on the console, "maven clean" starts downloading all 
dependencies, extensions have to be written in a XML scripting language 
that doesn't behave very intuitive, etc, etc.

Maybe it's just me and at 35 I'm getting old, but so far I'm not 
convinced that maven helps me more than it hurts. From what I hear 
maven2 is a bit better - contributions for converting the clirr build to 
m2 would be welcome.

Cheers, and sorry for the extra "h" in my original email,
Lars

maven :)

For BCEL I would need it for maven1 as it's we have not switched it =20
to maven2 yet. But I might give that a go anyway.

Re: [Clirr-user] using clirr through maven

Thorsten,

Maven2 support has not been implemented yet and as far as I know nobody 
is currently working on that. Contributions would be extremely welcome.

Aside from clirr itself, I don't use maven, so sorry, I can't help you 
much. If you just need a quick check before a release (I saw your 
message on jakarta-commons) I would recomment simply using the 
commandline tool, write the results to a file, and search for "ERROR".

Maybe Vincent (plugin author) can provide improved installation 
instructions for the maven plugin?

Hey guys,

it seems like the instructions on how to get clirr to work
with maven are pretty much out-of-date. Anyway ...I need
clirr for a release. So any help to get it working with maven1
is appreciated. Is there support for maven2 yet?

[Clirr-user] Clirr 0.6 is available

[<lak...@t-...>]

The Clirr team is proud to announce the immediate availability of Clirr 
0.6.

Clirr is a tool that checks Java libraries for binary and source 
compatibility with older releases.

This version contains several bug fixes and usability improvements. It 
also introduces an API that should allow the creation of Clirr IDE plugins.

As usual, the detailed list of changes to the core checker can be found 
at http://clirr.sourceforge.net/clirr-core/changes-report.html

Enjoy,
Lars

Re: [Clirr-user] Feedback

[<lak...@t-...>]

Wow, thanks for such a detailled analysis. I have added most of your 
points to the feature request tracker. Please add further suggestions 
there so I can keep track of things.

I'm not sure what you mean in #4, though. Here is some sample code that 
uses only official API from commons-collections 2.1:

Iterator i1 = myCollection.iterator();
ProxyIterator pi = new TransformIterator(i1);
Iterator i2 = pi.getIterator();

I haven't tried it, but I think adding getIterator() to 
TransformIterator doesn't help here because the class verifier will 
already reject the second assignment. So can subclasses really cope with 
the removal of a superclass if the removed class is public?

Again, thanks for your feedback - I'm already working on some of your 
other suggestions.
Lars

[Clirr-user] Clirr 0.2 is available

[<lak...@t-...>]

Hi,

I have released the first public version of Clirr, available via the 
sourceforge project page at http://sourceforge.net/projects/clirr/

Enjoy,
Lars

Re: [Clirr-user] How is the project going?

[<lak...@t-...>]

Hi Stephen,

thanks for your interest in the project. I didn't have time for Clirr 
since the beginning of this year (job and my other opensource projects 
like Checkstyle and OpenOrb) so during recent months there hasn't been 
any active development.

I'd say that the current version number 0.2 reflects the development 
status pretty well: Alpha

    * somewhat usable (detects many compatibility errors already)
    * some compatibility problems are currently not detected
    * probably not configurable enough for many users

At my job I have the same problem for our own internal libraries that 
you have for Jakarta Commons, so I will probably soon start active 
development again. Having Jakarta Commons as potential serious users 
will definetely increase my motivation.

Have you tried to integrate clirr in one of your projects? I'd be happy 
to help and resolve any problems you might have, add features you need - 
and of course your patches are welcome, too :-)

I just ran "maven test" on CVS HEAD and I cannot reproduce a test 
failure. Which test is failing for you?

Cheers,
Lars

PS: Now that sourceforge has added spam filters I have allowed postings 
for unsubscribed users.

[Clirr-user] How is the project going?

[Stephen C. <sco...@bt...>]

Hi,
Your project got spotted by Apache Jakarta Commons, which is why I'm writing
to you. We are looking for a binary compatibility tester for commons
libraries.

The main question is how far progressed is the project? I downloaded the
latest source, and a maven jar failed with a test failure.
