[gwt-contrib] Java8 emulation

[Jens]

Hi, 

whats the current situation of adding Java8 emulations to GWT?

I would like to fix the current emulation of @FunctionalInterface (wrong 
package and missing imports), add java.util.Optional[Int|Long|Double] 
emulation and like to see java.util.function interfaces in trunk committed. 
That would allow us to further work on stream API emulation which would be 
nice to have in GWT 2.8, right? Just having Java8 syntax support seems a 
little weak to me for a new release.

Currently my patch for java.util.function can not be verified by Jenkins 
because it runs the presubmit task with sourceLevel 1.7 (and Java7 I 
think). So I assume that the next GWT release should be compatible to 
Java7. 

Does this mean that any emulation of Java8 APIs should be done using Java7 
syntax ( = no lambdas in emulation code) ? What about default methods in 
emulated code when people use JDK 7 with GWT? 

So how should Java8 emulations be contributed?

Adding new classes should be pretty straightforward.

That would be my vote - we don't want to force people to use Java8 just yet.

Re: [gwt-contrib] Java8 emulation

[Colin Alworth]

The trick seems to be that it is not going to be possible to add Java8 emul
code without actually using Java8 - while lambdas can be avoided, defender
methods cannot. If you need to provide a new interface like Consumer, the
supersource *must* have the `default` method(s), or it won't actually be
Consumer.

If it were just those types, it would be possible to move them into their
own module so developers would need to inherit's the Java8 module to get
access to them, but the Collection interface itself needs to be changed to
add `default Stream stream()`, plus the implementation, or else all
implementors of Collection (and Set and List) need to have an
implementation added. Even then, Stream would need to be emulated, which
references Consumer, so we can't have it be a separate module...

...or am I over-complicating matters?

Well, certainly there are things which will require further support in GWT
and in the build, but things like adding j.u.Optional can be done without
that.

Couldn't we configure sonatype to keep at least the last snapshot even if
we don't update the repository (because the build failed)  ?

Re: [gwt-contrib] Java8 emulation

['Roberto Lublinerman' via GWT Contributors]

I think we make run presubmits with Java 8. AFAIK presubmit only build the
compiler (to see that is buildable) and run checkstyle. We will still run
our main continuous build in Java 7 and there is an alternate continuous
build with Java 8 (which is now broken).

Can someone look at those failures? Internally apart from the 2 failing tck
tests (which we could disable until we upgrade validation) all the others
are passing.

I am not sure why

Ok but then it is still with sourceLevel 1.7 by default. Here [1] is a 
presubmit log from february that complains about lambda, default methods 
and static interface methods.

But that is just job setup in Jenkins. Its more interesting how to 
contribute emulation code that requires Java 8. Should GWT provide 
user/super/com/google/gwt/emul and user/super/com/google/gwt/emul8 and then 
let ANT produce two gwt-user libs? I am pretty sure you have already talked 
about that offline and have some ideas...

Re: [gwt-contrib] Re: Snapshot repo?

[Ali Akhtar]

It appears that the web bindery jars are still missing on sonatype?

[ERROR] Non-resolvable import POM: Could not find artifact com.google.

/home/ali/.m2/repository/com/google/gwt/gwt/2.8.0-SNAPSHOT/gwt-2.8.0-SNAPSHOT.pom,

There don't seem to be any jars 
at

Re: [gwt-contrib] Re: Snapshot repo?

[Ali Akhtar]

Or it might be that the pom file is missing? It fails at "Downloading: 
https://oss.sonatype.org/content/repositories/snapshots/com/google/web/bindery/requestfactory/2.8.0-SNAPSHOT/requestfactory-2.8.0-SNAPSHOT.pom";

If I use https://github.com/manolo/gwt-snapshot/ as a repo, it compiles 
without complaining

[gwt-contrib] Re: Snapshot repo?

[Ali Akhtar]

Ah, https://oss.sonatype.org/content/repositories/google-snapshots/ is the 
repo. Got it, working now.

+1 in favor of not deleting the last working build, please.

Re: [gwt-contrib] Java8 emulation

['Goktug Gokdogan' via GWT Contributors]

For Java8 emulation, what is my mind is to have Jens patch and have
collection API improvements (Streams) to be available. There are few issues
and steering committee is discussing (or will discuss) about it.

See the discussion in
https://groups.google.com/d/topic/gwt-maintainers/X6WnH3C-nzg/discussion

For some reason that discussion doesn't seem visible to everyone but in
short we are planning to make Java8 only release with an option for
community to make it work with java7.

Here is related part rephrased:

--

For supporting java7, the deprecated but not dropped dev-mode is the source
of the problem (java8 emulation doesn't compile with java7, so we compile
with java8 mode which produces byte code incompatible with java7 VMs).

There are three ways to make it work:
1- The community can extract the java emul from 2.7 release and bundle it
with 2.8 (we didn't remove the source-level flag yet to keep this as an
option for the community).
2. Somebody can contribute a byte code rewriter that re-writes java8
byte-code as java7 by re-purposing retrolambda.  It doesn't need to be
perfect as the user-code will only use java7 features (I thinking this is
the cleanest one).
3. I don't remember if I have tried hard enough to force java7 compile with
devmode; but if somebody is interested, he/she can a look at this one as
well (i.e. set sourceLevel to 7 in dev-mode and try to make that work).

All of these all assumes that user code is kept java7 compatible and trying
make GWT 2.8 work in java7 VM environment. If the developers just upgrade
VM in developer workstations to a Java8 VM (upgrading to Java8 SDK is NOT
required), none of these is needed so I think the community doesn't need to
bother with it. However if there is enough demand and interest from the
community, they could take one of the options to make the 2.8 a java7
compatible release.
