Testing GWT 2.9.0 for release

[Colin Alworth]

Hi all,
We have a build ready to test for GWT 2.9.0, and are looking for volunteers to verify that things are behaving properly on a variety of platforms. If you have an hour or two free and can help us out, we would appreciate it.

We're hoping for a cross-section of testing that verifies
 * JVM version: 8, 11, 14
 * Operating System: Linux, OS X, Windows (8, 8.1, 10)
 * Browser: Chrome, Firefox, Safari, IE11, Edge

If a tester has access to more than one of these at a time, the tests will probably go more quickly than two individuals testing the same setup. Please note that while Microsoft still provides virtual machines for testing purposes, only Windows 10 appears to be available, though with both IE11 and Edge (https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/).

Please send me an email off-list with the various options you are able to test, and I'll get you on the testing spreadsheet.

Thanks!

[Juan Pablo Gardella]

Hi Colin,

Could you please share the spreadsheet again?

Yeah I’ll send it out once we’ve got some volunteers, and figured out who is able to test what configurations.

Hello,

Any chance to include the following patch in 2.9?

https://gwt-review.googlesource.com/c/gwt/+/19800

It has been sitting in Gerrit for years and it's a shame that the core GWT code doesn't convert dates correctly in all timezones.

Thanks in advance.

Absolutely, I build on Windows during dev, run SDM, etc...., run

[Manfred Tremmel]

Hi Colin,

I've build and tested my libs and GWT-Applications this weekend against GWT
2.9.0-rc1 and elemental2 1.0.0. The good news is, everything compiled and
workes. I'm happy, to switch elemental2 form 1.0.0-RC1 to 1.0.0, which fixes
some problems I had in the past, so I can remove some JSNI Workarounds.

System: Debian GNU/Linux 10 with openJDK 11. For years, I don't use browser
specific permutations, only the "safari". Tested Browsers: Chromium and
Firefox.

What's the timeline for removing bean validation out of gwt-user package, it's
nearly four years, since it was deprecated and it's still a hack to get gwt-
bean-validators as replacement into the projects (dependency suppressions,
correct inherit order, supersource replacements of existing gwt classes).

Manfred

Speaking of that, it's breaking HEAD-SNAPSHOT: https://groups.google.com/forum/#!topic/google-web-toolkit/7_-tpK8s_cM (see discussion in linked issue)

[Colin Alworth]

We're having an issue related to the java7->java8 update, the build isn't properly including the full sources for the included sample projects. By itself, not a big deal, but it could imply that other assumptions of the ant build are broken too. I'm looking into it, we'll have an updated release candidate when we figure it out.

https://github.com/gwtproject/gwt/issues/9682: The 2.9 candidate was cut before the java.io changes came in, so this will not be included in the first 2.9 at least, though will likely show up later (See the 4th point in this email).

Removing validation: as a rule, the main GWT project rarely, if ever, removes anything within a major release. This is very deliberate, so that updating to the latest release (to fix security issues, to support newer/changing/breaking browsers, improve performance) is accessible to stable projects in maintenance mode, with no surprises. Since gwt-dev and gwt-user are strongly tied to each other, it isn't feasible to even suggest that someone update part of their project, but continue to use older jars (such as updating the compiler to fix some issue, but still keeping an old gwt-user so that the now-deprecated validation doesn't change or disappear). This is why each module that is being broken out will now live in its own git repo, own jar, and be versioned separately from the others. My best guess here is that we can try for a "minimal gwt-user" which just has enough to let the compiler work, and assume that developers switch to the org.gwtproject modules that they want, plus anything thirdparty like validation. That said, validation is basically the only thing that _isn't_ ready for j2cl, and there is a small gwt-validation project that has gotten started that is compatible with both gwt2 and j2cl - do you have plans to finish https://gitlab.com/ManfredTremmel/gwt-bean-validators/-/issues/3? Both topics (further modularizing gwt-user, and apt for validation) are probably better discussed in another thread, or in gitter.

CL 19800: Agreed, sucks that this fell through the cracks. Two thoughts: lets get that into gwt-i18n as soon as possible, and lets try to land that patch after 2.9.0 is cut and shipped. The plan is that 2.9.x gets updated regularly (6-8 weeks sort of thing) with any changes, and marked with a date rather than just an occasional version.

[Juan Pablo Gardella]

I verified GWT 2.9.0-RC1 in one of my applications without issues. The tests I could not complete due an ant issues to build the samples.

I've downloaded

- gwt-user-2.9.0-RC1.jar (https://mvnrepository.com/artifact/com.google.gwt/gwt-user/2.9.0-RC1)

- gwt-dev-2.9.0-RC1.jar (https://mvnrepository.com/artifact/com.google.gwt/gwt-dev/2.9.0-RC1)

- gwt-servlet-2.9.0-RC1.jar (https://mvnrepository.com/artifact/com.google.gwt/gwt-servlet/2.9.0-RC1)

- jsinterop-annotations-1.1.0-RC1.jar (https://mvnrepository.com/artifact/com.google.jsinterop/jsinterop-annotations/1.1.0-RC1)

to test our biggest application against RC1. However i got the folloing error when trying to compile:

     [java] Loading inherited module 'XXX'
     [java]    Loading inherited module 'com.google.gwt.core.Core'
     [java]       Loading inherited module 'jsinterop.annotations.Annotations'
     [java]          [ERROR] Unable to find 'jsinterop/annotations/Annotations.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

The problem is that jsinterop-annotations-1.1.0-RC1.jar is missing the Annotations.gwt.xml. I easily added Annotations.gwt.xml into the jsinterop-annotations-1.1.0-RC1.jar and compilation works like a charm.

I'm wondering if i downloaded the wrong jsinterop-annotations-1.1.0-RC1.jar?

Thanks,

Michael

[Ignacio Baca Moreno-Torres]

gwt-user depends on jsinterop-annotations:sources (with the sources qualifier), and jsinterop-annotations:sources contains the Annotations.gwt.xml. It really seems right.

We have tested in various projects and works perfectly. But, we downloaded a corrupted gwt-user in one of the tests, and we need to remove it manually so maven downloads it again (from the .mw directory). It's a dummy thing, I know, but try it just in case.

[Michael Seele]

That helps, thank you.

[Colin Alworth]

Update on the broken samples in the gwt distribution:

The issue is some kind of interaction between Java 8 and ant - when a URL is read from the classloader for a directory within a jar, it had a trailing slash. When running the GWT webappcreator from command line, this didn't happen, when running within ant in Java 7 this didn't happen.

The patch is up as https://gwt-review.googlesource.com/c/gwt/+/22320.

An alternative fix could be to normalize those paths inside the WebAppCreator and remove trailing slashes - we experimented with that at first, but once we discovered that it was ant's classloader which was causing this and _not_ just Java 8, it made more sense to fork the task. This also brings the WebAppCreator task in line with all other <java> tasks in the ant build.

hi

1) there is no gwt-maven-plugin:2.9.0-RC1 so I used 2.8.2. 

2) i have the following error, looks strange because TryStatement definitely has public "resources" field

Maybe you have an overriden version of the JDT compiler on classpath that is incompatible with JDT compiler version from GWT dependencies.

[Alexander Tarasov]

thanks, you were right. 

but we use JDT ECJ for lombok support.

without lombok does not work unfortunately

Do you use lombok in client code? If so, you may try to align your JDT compiler version with one that used by GWT.

If lombok is used only in server code, then ensure that the server code and the client code, both are placed in different maven modules.

Maybe there are other ways, but I'm not familiar enough with lombok.

Hi,

When moving to gwt-2.9.0-RC1 and elemental2 1.0.0 (from elemental2 1.0.0-RC1), it seems that HTMLElement no longer has a click() method defined. Is that intentional? Is there alternative? We use this to trigger the File Dialog for file inputs.

Otherwise compilation successful on OpenJDK 8 and Linux with minor tweaks for elemental2.

There's HTMLInputElement#click(): https://javadoc.io/static/com.google.elemental2/elemental2-dom/1.0.0/elemental2/dom/HTMLInputElement.html#click--

This might be intentional, or not, but it's Elemental2, it's orthogonal to GWT (other than the dependency requirements regarding which version of Elemental2 is compatible with which version of GWT).

[Jim Douglas]

I've got the same build error that Michael reported here, and I'm not sure how to get past it.

I couldn't find a complete self-contained gwt-2.9.0-rc1.zip distribution, so I hacked one together by downloading 2.8.2 from here:

http://www.gwtproject.org/download.html

I extracted that GWT 2.8.2 SDK to ~/Documents/gwt-2.9.0-rc2, then I downloaded all of the relevant 2.9.0-RC1 jar files from Maven:

https://mvnrepository.com/artifact/com.google.gwt

And I dropped those jar files into that directory. The result was a hacked attempt at a 2.9.0-rc1 GWT SDK, with a root directory that looks like this:

Then within Eclipse, I did a "GWT Compile Project", which failed right away with this error message:

Loading inherited module 'com.basis.bbj.web.gwt.EnglishOnly'

   Loading inherited module 'com.google.gwt.core.Core'

      Loading inherited module 'jsinterop.annotations.Annotations'

         [ERROR] Unable to find 'jsinterop/annotations/Annotations.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

So first question: How do I get it to recognize the jsinterop-annotations-1.1.0 that I did drop into that directory?

And second question: Is there an easier way to download or construct a traditional GWT SDK to test GWT 2.9.0-RC1 in Eclipse?

[Colin Alworth]

Jim, the download zip is available for people who are helping with pre-release testing - it is an error that the jars made it into maven central before we completed this acceptance testing. Once we finish testing, we will announce it and make a zip generally available for download.

With that said, can you confirm that the jsinterop-annotations-1.1.0-sources.jar jar does _not_ contain a file at jsinterop/annotations/Annotations.gwt.xml'? I am suspecting either you got a corrupt jar, or that this sources jar didn't end up on your compiler classpath after all.

$ unzip jsinterop-annotations-1.1.0-RC1-sources.jar

[Colin Alworth]

Jim, from this result, your classpath isn't correctly configured - the file is there in the jar, as expected, but GWT isn't seeing it, so doesn't know to include these sources.

I'll reach out off-list once we have a new zip and are ready to start testing again.

I know replacing generators is to long on my todo list and it always was
postponed because something else was more important. In June I'm three weeks
on vacation and it's on first place of my todo list for this time.

[Colin Alworth]

Excellent - reach out in https://gitter.im/gwtproject/gwt, https://gitter.im/gwtproject/gwt-modules, or https://gitter.im/vertispan/j2cl for any discussion around this, and people who are eager to help test.
