New IBM VME available soon
Hi all,
I'm pleased to announce that a new 5.0 level IBM VME will be made
available soon at:
http://www-128.ibm.com/developerworks/java/jdk/harmony/index.html
The new VME downloads are named Harmony-vme-win.IA32-v4.zip and
Harmony-vme-linux.IA32-v4.tar.gz. I would like to stress that if you
download these packages now, they will *not* work with the class library
code currently in Harmony Subversion. I have created a new JIRA
(HARMONY-1084) containing patches for Harmony classlib and the Eclipse
Harmony plugin which are required to be able to use the new VME. The
patches make the following changes:
- Change Java build target from jsr14 to 1.5 :)
- Change the bootclasspath system property name from
com.ibm.oti.system.class.path to org.apache.harmony.boot.class.path
- Create a new org.apache.harmony.luni.platform.Environment class that
contains two (currently stubbed) getenv() methods. Once these methods
are implemented, VM writers will be able to redirect System.getenv()
calls to this class.
- Rename clearvm.dll/libclearvm.so to harmonyvm.dll/libharmonyvm.so,
and update the launchers reference to this library.
- Rename clearvm.properties to harmonyvm.properties, and update the
Eclipse plugin to find this file.
- Update tests.api.java.lang.reflect.ArrayTest and
tests.api.java.lang.ThreadGroupTest to reflect changes between 1.4 and
5.0 behaviour.
Once the classlib patch has been applied, you will need to download the
new VME in order to continue developing with the IBM VM. The previous
version of the VME will no longer be compatible.
I will send out a further mail when the new VME is available to download
and use.
Regards,
Oliver

On Windows at least this actually has nothing to do with class loading.
You simply cannot modify an environment variable of a running process
(at least not from outside that process). Every process has its own
copy, so changing the parent process' environment makes no difference,
nor does changing the environment of a child process.

Now that I think about it, I remember someone complaining once on a Java
newsgroup that changing the CLASSPATH environment variable had no effect on a
running JVM. He got an education in Java class loading. :-)

ok, I just tested myself on Windows and it seems that the RI ignores
environment variable changes, so I guess it's fine if we stick with what
we have in Harmony.

I have tested on linux that a native code to setenv, but RI still gets
the original value if use System.getenv. While on windows, I fails to find
the "setenvironmentstring". So Harmony behaves just like RI.
Would you really ever want that? Seems to be a safety issue.

It's not possible that the environment variables could change during the
lifetime
of the VM? If, for example, a Java program made a call out to native
code, isn't it
quite possible that that native code to alter the environment variables,
and thus
when we return to Java the environment of the process has changed?

Hi, Oli:
It is really a problem that System.getenv fails to behave as RI on
windows. I will fix it by get env string out by os function such
as getenvironmentvariable and getenv. Thank you for your tips.
Besides, the returned environment variables is only defined in
the process of the java application, for example, the command windows, and
remains the same during the life cycle. :)
Thank you, Oli.
Good luck!

Re: New IBM VME available soon
Posted by Oliver Deakin <ol...@googlemail.com>.
Hi Paulex,
Thanks also to Leo for providing this implementation. I tried a couple
of simple
tests on Windows on the getenv() and getenv(String) methods.
The getenv() method seems to work fine, giving me a list of the
environment properties.
I compared this list to those output by the Sun and IBM VMs, and found only
one property missing (the rest were the same). It is a property with key
"=::"
and value "::\" (without the quote marks). I have no idea what they are
for or
whether they are important. Can anyone shed any light on these?
When testing the getenv(String) method I hit a snag. If I try the
following line:
System.out.println(System.getenv("PATH"));
on the current classlib, I get "null" output, whereas on J9 and Sun 50 I get
the correct path contents printed. I looked a little closer and found that
this is because my path environment variable is actually called "Path". So
it seems that on Windows the RI and IBM vms are case insensitive,
but Harmony is not. The spec for getenv(String) states:
"On UNIX systems the alphabetic case of 'name' is typically significant,
while on Microsoft Windows systems it is typically not. For example, the
expression 'System.getenv("FOO").equals(System.getenv("foo"))' is
likely to be true on Microsoft Windows."
It seems we see this difference with Harmony because the current
implementation tries to carry out a lookup in a Map with the environment
variable name as the key. Since this lookup is case sensitive, we do not
find
the entry.
IMHO we should match the RI behaviour on this one. I would propose
a solution that involves making Environment.getenv(String) carry out a
direct call to a native function that in turn calls
GetEnvironmentVariable() [1] on
Windows and (I think) getenv() on Linux[2]. This way the case-sensitivity
should match that typical to the platform. Do you agree?
I would also remove the static initialisation block from that class, and
move
its contents into the getenv() method instead, just returning the Map
directly without need to staticly store it in the class. I suggest this
for two
reasons:
1) It reduces the long term memory requirements of the Environment
class. With the current implementation all the Strings are loaded into
memory the first time the class is loaded, and then they stay in memory
until the class is unloaded or the VM exits, even if they are never used
again.
2) With the current implementation, it is possible that the returned
environment variables are out of date. There could be a scenario where
the Environment.getenv() method is queried, then some actions happen
in an application that cause environment variables to change, and the
getenv() is queried again. The result from getenv() would not change
frmo one call to the next even though the environment has. I think the
right solution here is to rebuild the Map every time getenv() is called.
What do you think of these suggestions Paulex, Leo?

Oliver

Oli
Thanks Leo for volunteering, I've checked in his patch for HARMONY-1155
at revision r431560, i.e., the implementation of Environment class,
would you help to verify if that implementation is OK to use? or it
takes effect automatically at once? Thank you.

Great news.
In the future, could you please prefix the subject line with something
appropriate, like [general]? It helps people prioritize and such...
