[classlib][jndi][compat] Shoud Harmony support ri's ldap provider specific properties?

[Regis <xu...@gmail.com>]

Hi,

There are some provider-specific environment properties defined in ri's 
ldap provider, such as,
com.sun.jndi.ldap.connect.timeout,  com.sun.jndi.ldap.trace.ber

I'm not sure how to deal with these properties, should we support them 
for compatibility reason
or we just supply Harmony's provider specific properties, like 
org.apache.harmony.jndi.ldap.timeout?

Any thoughts or suggestions?

Best Regards,
Regis.

I prefer to use Harmony specific properties too, after all it's 
Harmony's provider.

Yes, I think we would have Harmony specific ones first, then, if there were
strong reasons we could add supports for ri's.

Hi Regis,

I don't know the ldap area that well, but in my experience some of these
kinds of properties can be quite implementation-specific and therefore
it's not really necessary or helpful to support them in general.  However
I'm not sure what makes more sense if we want to have a property that
essentially does the same thing.  I would probably say we should have a
Harmony one because I think that's what people would expect when they're
running Harmony, but I don't feel that strongly about it.

Regards,

Sian

Sure, we can implement these features without looking to the code, but 
the question is
should we use the same property name as ri ? such as 
com.sun.jndi.ldap.connect.timeout,
i prefer to replace it by org.apache.harmony.jndi.ldap.connect.timeout.

Best Regards,
Regis.

<sorry for late reply, just returned from the long trip> FYI, DNS
provider implementation from the org.apache.harmony.jndi.dns package
uses Harmony-specific property names. But I agree with Tim that for
compatibility reasons it would be nice to support both properties
sets.

Would it be possible to code our implementation to look at
org.apache.harmony properties, then in the Sun compatibility module have
some early init code that copies any value specified as com.som.whatever
to org.apache.harmony.whatever?  Just trying to get the best of both
worlds<g>.

Nothing that starts "com.sun" is part of the official spec, although as
Regis said, in this case it would be possible to implement these
properties without looking at the code.  If we're talking about the general
case it may not be possible or desirable to do this for other properties.
For example a property that improves some kind of performance on another
implementation would be unlikely to have the same effect on Harmony even if
we did support it, which could be confusing for users.

Are this properties well documented/included to the spec? IOW, is it
possible to implement them without looking to the code?
