[classlib][nio] JDK 7 / WatchService support
Hi there,
I'm the author of jpathwatch (http://jpathwatch.wordpress.com), a library that implements the JDK 7 WatchService API, allowing Java programs to monitor directories without polling. It natively supports Windows, Linux, FreeBSD and OSX, with fallbacks for unsupported platforms and architectures.
jpathwatch supports JDK 5 and up, however, with JDK 7 jpathwatch will become somewhat obsolete (since JDK 7 obviously implements it's own WatchService API, together with the other nio2 features).
I'd be willing to donate jpathwatch to the Apache Harmony project. jpathwatch's API uses the same class interfaces and method signatures as the JDK7 WatchService API, it's only the package names that are different, which should be easy to change to fit into Harmony.
jpathwatch uses native libraries (implementing very thin wrappers around native OS functions), these will have to be integrated as well, which I think should also be quite trivial.
Please let me know if there's interest in such a donation.
Cheers,
Uwe
P.S.: Hope you don't mind the sneakemail address, I'm spam paranoid ;)

Hi Regis,

I just got a response from Patrick Steele-Idem, the contributor of the
patch. He asks what's required and suggests this:
"I hearby state that my patch to the jpathwatch library is licensed
under APL v2 (Apache portable license [1])"
(where [1] is http://www.apache.org/licenses/LICENSE-2.0)
Would that be enough? Where would he have to post this? On this mailing
list?

Hi there,
Yep, I've written it pretty much all myself. There are two (IMHO minor)
sources of external influence (besides the official JDK7 beta docs):
* There has been one occasion when someone contributed a patch which
extended the WindowsPathWatchService implementation to handle more than 63
watched directories. I modified it a fair bit before it went in.
* For a while I had a modified version of WatchDir.java [1] example in the
test driver. The code is part of the Java tutorial [2] on Sun/Oracle's web
site (look for 'WatchDir example' on the page to find the link).
Other than that there is no external influence I can think of.
Is that clean enough?
Cheers,
Uwe

GPL + classpath exception FWIW. (Personally I am baffled by the classpath
exception; I haven't a clue what "this library" or "independent modules"
translate to in Java terminology).
If Uwe is sole author then he can just add the option to use the code
under ASL.

Good question Ray, and I think it's OK if the owner hold the copyright and
re-license it. ACQ and ICLA should be the legal insurance.

Hi Jimmy,
Thank you for the information!
I have a question here, jpathwatch is in GPL license, can harmony use that?
I am not an legal expert, just curious.

Hi Uwe,
Welcome to Harmony community! It's very great news to us the Harmony
Project! Thank you very much in advance!
Yes Harmony currently have no Java7 branch yet but we can quickly
create one. With your code we have a big step towards jdk7 feature
completion.
To contribute to Harmony, you may have to fill ACQ and ICLA, I suppose
it won't be a big problem for you ( please refer:
http://harmony.apache.org/contribution_policy.html). And as a bulk
contribution, there is some process:
1. Will be donated via the project bug tracking system (JIRA) as a
contribution under the Apache License
2. Will be accompanied by a Software Grant or CCLA which will be
registered with the Apache Incubator
3. Will be registered in the Apache Harmony Bulk Contribution Repository
via a Bulk Contribution
Checklist<http://harmony.apache.org/bulk_contribution_checklist.html>
4. Will be made by an Authorized Contributor to Harmony (defined above)
Please mail if you have any questions. Looking forwards your
contribution. Let's cheer for this great time!
