[Lift] Re: JTA Transaction Monad - Early Access Program

2009-07-20 Thread Jonas Bonér

I'm really sorry. I never checked building with an empty maven repo.
Thanks for fixing it.

2009/7/20 Derek Chen-Becker dchenbec...@gmail.com:
 FYI, it looks like the Hibernate dependency you had in your pom was pulling
 in the javax.transactions:jta lib, which isn't available in maven repos. I
 added an exclusion to prevent that from breaking the build.

Thanks Greg. I would love to get your feedback on it.

 Jonas,

 i'm going to begin playing with it after i've finished the conversion of the
 DSL stuff to scala-query. The JTA monad should just fit with scala-query.

 Best wishes,

Thanks Tim. Thanks for staying on top of it. Derek has already looked
at it and seemed to like it. But I'll wait until I get Greg's
feedback.

2009/7/7 Timothy Perrett timo...@getintheloop.eu:


 Hey Jonas,

 I have no real use case to test it out - I was just interested in its status
 as conceptually it was very very clever and wondered where you were too with
 it. I think Greg or Derek are most likely to be able to give you valuable
 feedback as I believe they are using JTA already.

 Cheers, Tim

[Lift] Re: JTA Transaction Monad - Early Access Program

2009-06-10 Thread Meredith Gregory
Lifted,

i gotta say this thread of activity is just so cool. It's what i always
dreamed open source would be like. The community essentially gets to access
and think with each others' best minds and act with each others' best
talents to arrive on a path to a better concrete realization of feature,
function and design. We all know, individually and collectively, just how
hard it is to make excellent software and know that we're more likely to
achieve that aim working together. i can't help but notice that there is no
explicit representation of the profit motive here. Each of us might
individually be in contact with some aspect of profit motive, but it does
not have an explicit representation in this little snippet of process. That
gives this entrepreneur pause for thought.

Best wishes,

--greg

 Hey guys.
 
 I have hacked together an early draft of the JTA transaction stuff.
 
 I have wrapped it up in a monad. Here  are some examples of usage:

ctx.getEntityManager.merge(entity)

 If you don't like the monadic approach you can just use the high-order
 functions:
 
 TransactionContext.withTxRequired {
 ... // REQUIRED semantics
 
   TransactionContext.withTxRequiresNew {
 ... // REQUIRES_NEW semantics
   }
 }
 
 I have implemented the same semantics as used in the EJB spec.
 Required, RequiresNew, Mandatory, Supports, Never. All these are
 monadic objects in the TransactionContext object.
 I don't have a webapp to try this out, so I would be happy to get all
 kinds of feedback, but API wise and bug reports or fixes.
 
 This API is hooked into Derek's Scala-JPA stuff. I had my own impl of
 this but replaced it with Derek's work.
 
 Derek,
 please go through the integration to see if I have done it correctly,
 and where things code be improved.
 
 All committers,
 feel free to hack and change this code anyway you want.
 
 The code is in a branch (wip-jta-jonas), you can find it here:

 Check the ScalaDoc (or the source) for the documentation on usage,
 semantics etc.
 Also see the README for configuration in persistence.xml etc.
 
 Currently it is hard-coded to use the Atomikos Transaction library and

 As I said, this needs feedback and testing. Thanks.

[Lift] Re: JTA Transaction Monad - Early Access Program

2009-06-09 Thread Derek Chen-Becker
OK, one quick comment before I dive in: we generally want to depend on Maven
to grab dependencies. Right now you have a lib folder checked into git that
appears to hold the JTA libs and Atomikos. If that's the Sun JTA libs then
we can't distribute them. We generally use the geronimo JTA API, so you
could instead add dependencies to your pom.xml from the following:

http://mvnrepository.com/artifact/com.atomikos

dependency
groupIdorg.apache.geronimo.specs/groupId
artifactIdgeronimo-jta_1.1_spec/artifactId
version1.1.1/version
/dependency

Let me know if you have any problems with that. Now, on to the code!

I added the lib folder only since I have not been able to find the
atomikos and deps in any maven repo.
Now the user can install them in their private repo.
If they exist in a public repo then I will remove the lib folder.
Will switch to the apache libs.

Isnt LiftLogger extensible? Perhaps there would be some way to integrate it

What does Configgy have that Lift's Props and Logger doesn't?  I'm all for

 Jonas,
 We always use Maven to load dependencies.  We never use GPL dependencies.
  If you have a question about the license of a dependency and its use in

I am using Maven. But as I said I could not find the Atomikos in any
public library, putting them in lib will let the user easily install
them in their local repo.
Do you know if they are in any public repo?
Sorry about the license issues, didn't think about that.
I can remove them all in any case, even though that would make it
harder to use.

 What does Configgy have that Lift's Props and Logger doesn't?  I'm all for
 enhancing Lift to be as good as Configgy (and Robey didn't have the
 bandwidth to integrate Configgy into Lift, thus our own config management).

First I like the printf-style logging API, similar to slf4j. Nice to
use plus better performance.

Second I really like Configgys configuration API, plus that it is
integrated with the logging.
But this was just a comment from my side, I have no problem whatsoever
to use Lift logger.

  Jonas,
  We always use Maven to load dependencies.  We never use GPL dependencies.
   If you have a question about the license of a dependency and its use in
  Lift, please ping me privately.

 I am using Maven. But as I said I could not find the Atomikos in any
 public library, putting them in lib will let the user easily install
 them in their local repo.


I understand why you did it and that you had the goal of making it easier
for developers.



 Do you know if they are in any public repo?


I don't... but if they are not in a public repo, we have two choices:
hosting the JAR files on scala-tools.org (as long as the license allows us
to do that) or finding an alternative that is hosted in a public repo.  I'm
dealing with similar issues right now with ZooKeeper.



 Sorry about the license issues, didn't think about that.
 I can remove them all in any case, even though that would make it
 harder to use.

  What does Configgy have that Lift's Props and Logger doesn't?  I'm all
 for
  enhancing Lift to be as good as Configgy (and Robey didn't have the
  bandwidth to integrate Configgy into Lift, thus our own config
 management).

 First I like the printf-style logging API, similar to slf4j. Nice to
 use plus better performance.


We can add that to Lift's logger (which can sit on top of slf4j)

Also, note that all of Lift's logger parameters are call-by-name so there's
no evaluation unless the log level is met.




 Second I really like Configgys configuration API,


Can you tell me what you specifically like about it?

Thanks,

David


 plus that it is
 integrated with the logging.
 But this was just a comment from my side, I have no problem whatsoever
 to use Lift logger.

 /Jonas

  Thanks,
  David

  I am only depending on Lift through the Lift logger (switched from

  I am only depending on ScalaJPA through one single 'with

  I could move it.
  What do the rest of you guys think?
 
  2009/6/9 Derek Chen-Becker dchenbec...@gmail.com:
   Awesome! I'll take a look at the code. If you're basing this on
   ScalaJPA,
   would it be preferable to add the functionality there, or is there
   anything
   Lift-specific?

Re configgy.

I think it is a great balance between properties and xml, like pragmatic xml.
Simple as properties but with nesting, hierarchies, type conversions,
good override and defaults system (inheritance).
It also has notification of changes and a JMX API for management
(which I have not used yet).

Thanks Derek. Thanks for taking time to do a code review.
I'll add that to the README.
/Jonas

2009/6/9 Derek Chen-Becker dchenbec...@gmail.com:
 Jonas, the code looks great! I don't see any issues with how ScalaJPA is
 used. It's nice to see that this fits what you're doing well and I really
 like how this lets one use transactions without having to go with a
 full-blown JEE container. One thing that you might want to put into the
 README is a reminder that if you're going to be using JNDI along with an
 EntityManager then JTA is not only required, but should be handled
 automatically by the container. The only valid operation on a
 Container-managed EM (as pointed out by mrxtravis yesterday when he found a
 bug in ScalaJPA) is to set the TX as rollback-only.

 http://mvnrepository.com/artifact/com.atomikos

 I think that the dependency you want is:

 dependency
 groupIdcom.atomikos/groupId
 artifactIdtransactions-jta/artifactId
 version3.2.3/version
 /dependency

 Hey guys.

 I have hacked together an early draft of the JTA transaction stuff.

 I have wrapped it up in a monad. Here  are some examples of usage:

  for {
   ctx - TransactionContext.Required
   entity - updatedEntities
   if !ctx.isRollbackOnly
  } {
   // transactional stuff
   ctx.getEntityManager.merge(entity)
  }

 val users = for {
   ctx - TransactionContext.Required
   name - userNames
  } yield {
   // transactional stuff
   val query = ctx.getEntityManager.createNamedQuery(findUserByName)
   query.setParameter(userName, name)
   query.getSingleResult
  }

 If you don't like the monadic approach you can just use the high-order
 functions:

 TransactionContext.withTxRequired {
    ... // REQUIRED semantics

  TransactionContext.withTxRequiresNew {
    ... // REQUIRES_NEW semantics
  }
 }

 I have implemented the same semantics as used in the EJB spec.
 Required, RequiresNew, Mandatory, Supports, Never. All these are
 monadic objects in the TransactionContext object.
 I don't have a webapp to try this out, so I would be happy to get all
 kinds of feedback, but API wise and bug reports or fixes.

 This API is hooked into Derek's Scala-JPA stuff. I had my own impl of
 this but replaced it with Derek's work.

 Derek,
 please go through the integration to see if I have done it correctly,
 and where things code be improved.

 All committers,
 feel free to hack and change this code anyway you want.

 The code is in a branch (wip-jta-jonas), you can find it here:

 http://github.com/dpp/liftweb/tree/3783b9e2200cc57dd72baa1bd8cabdb1365ee923/lift-jta

 Check the ScalaDoc (or the source) for the documentation on usage,
 semantics etc.
 Also see the README for configuration in persistence.xml etc.

 Currently it is hard-coded to use the Atomikos Transaction library and
 Hibernate JPA, that would have to be configurable + some other options
 as well. See the TODOs in the code.

 As I said, this needs feedback and testing. Thanks.

 Now I have deleted the lib dir with all jars and fixed the POM.


Thanks!
