related issue for 1.1: yiisoft/yii#3110

[samdark]

A good idea is to wait a bit since Facebook HHVM team is working on the next version with much better support for standard PHP functionality and extras.

[cebe]

yep, 2.4.0 will make __get and __set work properly. This is the main issue with failing tests right now.

[artem-frolov]

HHVM 2.4.0 is released.

[cebe]

thanks for the info. need to wait until it is available on travis.

[cebe]

2.4.0 is available on travis and we are now running tests against HHVM regulary. However failing tests do not count against the overall build status right now.

Here is a HHVM build:
https://travis-ci.org/yiisoft/yii2/jobs/19992420

[cebe]

Current issues open with HHVM:

• OAuth extension uses a parameter that is not implemted in hhvm: http-build-query enc_type parameter and constants missing facebook/hhvm#1485
• Undefined property: PDOException::$errorInfo PDOException does not have errorInfo property facebook/hhvm#1412
  This is only partially fixed as the error codes do not seem to be the same as with normal PHP. This breaks places where we check for table existence.
  https://travis-ci.org/yiisoft/yii2/jobs/19992420#L910
• pass by reference to call_user_func_array Giving parameters to call_user_func_array() by reference does not work. facebook/hhvm#1486 -- seems to work in 2.5-dev...
• https://travis-ci.org/yiisoft/yii2/jobs/19992420#L932 there are still issues with magic getters and ArrayAccess interface. Need to investigate the cause and report this to HHVM.
• Not sure whats wrong here: https://travis-ci.org/yiisoft/yii2/jobs/19992420#L1048
• inconsistent behavior of HHVM makes numbervaidator fail when using PHP_INT_MAX + 1: Integer overflow behaviour facebook/hhvm#1458

When I try to run my Yii2 site (based on advanced template) I get this error:

I noticed that the file involved (/var/www/vendor/yiisoft/yii2/di/ServiceLocator.php) was updated a few hours ago, so maybe this introduces a new incompatibility?

[qiangxue]

Seems already fixed? facebook/hhvm#1995

[samdark]

Travis for HHVM is currently broken so we can't be sure. Anyway, this is not a showstopper.

[gimox]

hi what about yii2 and hhvm ?
have you some news?

[samdark]

99.8% compatible.

[gimox]

it's about yii2 ?

i read in hhvm site 99.8 for yii1

[samdark]

Ahh, right, it's about 1.1.

[gimox]

i'm courius to know somethink about yii2 and hhvm, i see that @cebe it's working on.
hhvm end php hack are very interesting... and we are planning to use it...

[basil-inc]

Same here, I'm eagerly awaiting compatibility. I'm also curious about the first major framework to convert to the new Hack language. I would actively support such a move for Yii2 in the mid-term future, but I understand that this would probably alienate a large part of the user base who rely on shared hosting based on the Zend PHP runtime.

[gimox]

php need a bump....
hhvm is good for enterprise, hack language can be the php that we need.
but now we are on a php compiled with variable declaration = java.

the goog news is that hack is retro compatibile with php.
so, when yii2 has 100% compatible with hhvm we can try it with hack....

[samdark]

@docsolver no, Yii will not be converted to Hack for the reasons you've mentioned.

@gimox hack is not backwards compatibile with php. HHVM is. That's why HHMV is important for Yii while Hack isn't.

[gimox]

@samdark you right, hack interoperates as php but is not 100% compatible (only simple script) so has no sense to use it now, it's too young...

hhvm is the future...

[samdark]

Added HHVM build status from http://hhvm.h4cc.de/ to issue header.

[gimox]

Thanks, yii2 now is in unknow status.

[basil-inc]

Since the release of HHVM 3.0.0 I got my Yii2 site working, but it crashes on a lot of things. I already logged two issues, but I also don't want to delay the beta release date. Maybe HHVM support can be a next milestone?

[samdark]

That's not a priority. If you want to help you can track these crashes down to simple PHP code pieces and submit to HHVM repo issue tracking.

[basil-inc]

Ok, I'll try to!

[cebe]

sent a PR to add yii2 to the official test suite: facebook/hhvm#2953

[samdark]

yiiunit\framework\helpers\ArrayHelperTest::testMultisortUseSort
Parameter 1 to array_multisort() expected to be a reference, value given

facebook/hhvm#1486 is still there.

[cebe]

yes, I know

[cebe]

all tests are passing.

[csim-sg]

Is Yii2 failing the HHVM test after all the new commits?

[cebe]

no, why do you ask?
