[Sablevm-developer] lt_dlopen(NULL) dependency eliminated

[Etienne G. <gag...@uq...>]

Hi all.

I have checked in staging my adaptation of Melanie's code to eliminate
dependencies on a working lt_dlopen(NULL)/lt_dlsym() pair.

Hopefully, this change will greatly simplify porting SableVM to new 
platforms.  Why not a "real Windows" port, soon, using Microsoft compiler?

In order for this code to work, it is *imperative* that all internal
native methods (e.g. Java_*) to be defined as:

JNIEXPORT ...
Java_... (...)
{
...

Where "Java_" starts on the first character of a line, and the "(" of 
formal parameters is on the same line.  If you do not follow this 
requirement, you method won't be found at runtime...  You've been warned;-)

Anyway, this should be true of *all* functions in SableVM.  You're 
welcome to fix any function that does not abide by this rule. :-)

Etienne

Thank-you for the clarification.  I just wanted make sure I didn't go 
and do something terrible.

Anyway, the tag is there now.

Well, assuming the result would be just the same, as if you did the
merge in the right place - then sure. But why not do it the right
way, in the right place in the first place?

The merge policy is getting especially important when merging things
into staging and further.  There's nothing that prevents you from being
inacurrate and messy in your own sandbox.  If you think that this
information is good enough for you - then, I think it's fine.

The reason why merge policy forbids modifications not strictly necessary
to the merge itself is, as I read it, that if the merge gets reverted
for any reason - these changes are lost.  The other reason is that if
you want to repeat the merge in another place/time, you know exactly
what was merged by looking at the log message.

In short: it's just much better and easier to abide by the policy ;-)

Cheers,

of course i meant to type "svn merge -r 2132:2144 ..." here.

Re: [Sablevm-developer] branch permissions and tag creation

[Chris P. <chr...@ma...>]

Hi Etienne,

Okay, thanks.  So just two more quick questions:

1) Under the new merge policy, is it acceptable to create the 
inflate_thin_locks/ branch in my sandbox, copy the merged changes from 
the working copy of the tag I just created, and then commit that with a 
"Merged ..." message?

2) I merged '-r 2132:2143 sandbox/sablevm/' into my 
tags/inflate_thin_locks/ working copy.  During the merge, I noticed 
there were some very small changes or comments I needed to add.  I added 
the comments to my main sandbox/sablevm/ branch as well as the 
tags/inflate_thin_locks/ branch, and committed the changes in 
sandbox/sablevm/ as r2144.

I was planning to write something like

"Merged with command:
svn -r 2132:2144 ..."

as my log message.  Is that sort of thing okay?  Or would I need to do 
two merges in this case?

Cheers,
Chris

Re: [Sablevm-developer] branch permissions and tag creation

[Etienne G. <gag...@uq...>]

Hi Chris,

You can't modify a tag.  A tag is a "snapshot".

You should make the changes in your sandbox, e.g.


svn cp svn+ssh://svn.sablevm.org/public/sablevm/branches/staging \
svn+ssh://svn.sablevm.org/public/developer/chris/sandbox/inflate_thin_locks

svn co ...
svn merge ...
svn ci

Then,

svn cp
svn+ssh://svn.sablevm.org/public/developer/chris/sandbox/inflate_thin_locks
svn+ssh://svn.sablevm.org/public/developer/chris/tags/inflate_thin_locks

You can create (svn cp) and delete (svn rm) tags, but you can't modify them.

[Sablevm-developer] branch permissions and tag creation

[Chris P. <chr...@ma...>]

Hi,

As an experiment, I am preparing a tag for Greg or David to
merge into staging.  It will contain a compile-time option to enable
inflating all contended thin locks (currently this is not done; see back
in the list about how in some situations it might give you a small 
benefit).  The option is called --enable-full-lock-inflation.

I did:

$ svn cp svn+ssh://svn.sablevm.org/public/sablevm/branches/staging
svn+ssh://svn.sablevm.org/public/developer/chris/tags/inflate_thin_locks
$ cd
$ svn co 
svn+ssh://svn.sablevm.org/public/developer/chris/tags/inflate_thin_locks
$ cd inflate_thin_locks/
$ svn merge -r 2132:2143 
svn+ssh://svn.sablevm.org/public/developer/chris/sandbox/sablevm

svn: Commit failed (details follow):

subversion/clients/cmdline/util.c:349: (apr_err=165001)
svn:    '/home/research/ccl/cpicke/inflate_thin_locks/svn-commit.tmp'

Is there some way for me to fix this?  Am I doing this the wrong way?  I 
looked in the documentation and in 'svn help' but couldn't see anything. 
  What's strange is that I was able to create the branch in the first 
place without any problems.  I am using a 0.37 client.

Cheers,
Chris

"make install" seems to be missing here. Are you sure the libffi*.so and
ffi.h headers are installed in tthe --prefix location?

Please try

export LDFLAGS=-L/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin
export CFLAGS=-I/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin/include
export LD_LIBRARY_PATH=/home/commgw/renaud/gcc/gcc-3.4.0/libffi_bin

which is the closest thing to what's written in the wiki and see if that 
helps.  If that doesn't work, please try something like

cd libffi_bin
../libffi/configure --prefix=${HOME} --host=arm-linux --build=i386
make
make install
export LDFLAGS=-L/home/commgw/renaud/lib
export CFLAGS=-I/home/commgw/renaud/include

Hi Fabien,

Can you please type out the exact sequence of commands you give, and 
changes you make to gcc files, from the beginning?  I know this is 
probably a lot to ask, but it seems we could spend a while trying to 
guess why SableVM cannot find libffi.  If you do this, someone like Greg 
more familiar with libffi will be able to help you much better.

Cheers,
Chris

You need to substitute '/home/gadek/' with the location where libffi is 
installed on your system.  Only if you installed it in your home 
directory will '/home/fabien/' (or rather '/home/`whoami`/') work.  Type 
'./configure --help' and look at the '--prefix' option, and maybe 
re-install libffi with './configure --prefix=${HOME}', or instead do 
something like 'find / -name 'libffi.*' to determine where it's already 
been installed.

Cheers,
Chris

[Fabien R. <re...@ne...>]

Hello ,

Thanks you for yours answers. That´s should be not so easy for me 
because I´m a beginner with all it´s related to  Java.
Humm, I´ve already a problem :

I installed libffi ( from gcc 3.4 tarball ).  All seemed ok but now I 
can´t ./configure sablevm :
checking for ffi_prep_cif in -lffi... no
***ERROR: libffi is missing

I set CFLAGS, LDFLAGS, LD_LIBRARY_PATH ( like in this page : 
http://devel.sablevm.org/wiki/LibFFI )

( I have the stable release 1.1.3 )

Cheers,

Fabien

Yes, thanks for noticing.
I add a little thing to the Hacker Guide and the INSTALL document
mentioning texinfo and the minimal version needed. Texinfo 4.2 was
release in April 2002 so I think we can safely recommend that version
(we are now at version 4.7).

Cheers,

Mark

Cleanly checkouted svm-cp compiles just fine on my x86 and w/o gtk

I checked in Google again and ifnotplaintext turned up a link to texinfo 
4.2.  My apologies (I used exactly the same textbox entry, so I really 
don't know what happened).

So I guess Classpath should now mark texinfo-4.2 as a dependency.

For Classpath people:  when trying to build sablevm-classpath with 
recent changes, makeinfo was telling me it didn't understand 
@ifnotplaintext, and my texinfo version was 4.1.

Chris

I am not sure what kind of "minimum" you think of.  A minimum
development suite needed to compile it all? I guess everything as usuall
besides gtk libraries (and pass --disable-gtk-pee to configure script).

I've just talked w/ jserv (see http://www.advogato.org/person/jserv/)
and he might be also interested in trying qt-embedded with SableVM.
Though I wouldn't want you guys to end up waiting for each other to
start the tests :-)

So, Fabien, just go on and tell us whether it works for you or what
are the problems, if any.  I am pretty sure that on the JVM side we'll
be able to help you in case of any troubles.  Though, if I get it right,
qt-embedded simply uses some JNI to glue QT to Java, so I am not
terribly worried.  Should be quite easy.

Re: [Sablevm-developer] sablevm-classpath broken in staging?

[Chris P. <chr...@ma...>]

Hi Etienne,

It was a fresh checkout, so generated files shouldn't be an issue. 
Anyway, I tried what you wrote on my failed tree, and 'svn st 
--noignore' returns nothing, and the build still fails.  I thought it 
might have something to do with texinfo software being out of date at 
Sable, but I checked and the installed version is 4.1 and dates back to 
March 4th 2002 (i.e. it's fairly recent).

I couldn't find "ifnotplaintext" in google, and I couldn't find it in 
`info texinfo` using 'i ifnotplaintext' either.

Tomorrow I'll try installing the latest texinfo (4.7) and see if that 
fixes things.

Cheers,
Chris

Re: [Sablevm-developer] sablevm-classpath broken in staging?

Hi Chris,

I've tested it already quite many times, and it simply works for me
on Debian/ppc, and even on OpenBSD/sparc.

Maybe somebody else will be able to reproduce the problem?

Make sure to:

$ svn st --no-ignore | grep ^I | awk '{print $2}' | xargs rm -rf

then make sure that

$ svn st --no-ignore

returns nothing.

Re: [Sablevm-developer] assert fails with new staging version

Hello,

I´d like to use sablevm with qt-emebedded on an arm embedded  platform. 
I don´t have X installed (I run graphics applications with the 
FrameBuffer).
What is the minimum I have to install to run java applications with qt lib ?

OK.  I analyzed the situation, and found out the bug.  It's not a
regression due to merging with newer classpath, as I thought it was.
It's an old, but hidden "false" bug that was exposed by the merge.

Mainly, when recursive initialization happens, the VM can actually
call a method on a yet uninitialized class.  The failing assetion was
thus a wrong assertion.  I have commented it, for now, as it would be
better to actually add an "in-progress-initialization" state and check
for this state in the assertion.

Of course, this only showed in debug mode, as it was an assertion bug
(and assertions are off in production mode).

So, you can consider the bug fixed in staging.
