HHVM: pthreads PHP classes
ZTS is a prerequisite of pthreads. ZTS is not used as the default because ZTS mode has some overhead associated with it. The HHVM documentation is just a clone of the php-doc repository, restyled, with some additional sections added for HHVM, this is why the pthreads documentation shows up in...
Nuclide IDE & Remote Server Setup with Watchman
hhvm,hacklang,watchman,nuclide-editor
It seems that Nuclide's WatchmanClient can't connect to your installed watchman for some reason. Note that the tests for WatchmanClient is currently disabled, but maybe it will show some useful error when you remove the x from line 20 of WatchmanClient-spec.js and run: npm test in the watchman-helpers directory or...
Phalcon Zephir vs APC vs HHVM Performance
php,apache,compilation,phalcon,hhvm
Zephir can't handle high level objective oriented code. Speed of your application will be worse than clean PHP way. Here you can find comparsion of clean PHP vs Zephir. https://github.com/dgafka/zephir-BookStore So, if you want to rewrite your application to zephir, think twice before you will do it. https://github.com/phalcon/zephir/issues/694#issuecomment-67987616...
Invalid operand type was used: array_uintersect expects array(s)

Receiving invalid filename error when converting first page of pdf to jpg
php,pdf,imagemagick,imagick,hhvm
OK...so the (kind of hacky) way to fix this in my situation is to use fopen() and then use setIteratorIndex(0) which is HIGLY unintuitive. But for those having the same problem...there you go! $pdf_handle = fopen('/path/to/file.pdf', 'rb'); $doc_preview = new Imagick(); $doc_preview->setResolution(180,180); $doc_preview->readImageFile($pdf_handle); $doc_preview->setIteratorIndex(0); $doc_preview->setImageFormat('jpeg'); $doc_preview->writeImage('/path/to/file.jpg'); $doc_preview->clear(); $doc_preview->destroy(); ...
How to Implement Singleton Pattern without Nullable
design-patterns,singleton,hhvm,hacklang
How do I assign a default value to a static property? If it's an object, like in this case, you can't. With primitives, you can do something like this: <?hh // strict class Foo { private static int $x = 0; // ... } However, for objects, you'd need...
Why does Magento remove my frontend cookie after using customer/session?

hhvm nginx not returning value for upload_max_filesize/post_max_size
Sorry for the noise, but it looks like this is a bug. https://github.com/facebook/hhvm/issues/4993
Did HHVM works only with HACK?
HHVM is a runtime engine for two programming languages, PHP and Hack. It is what actually executes your code and produces results, just like the Python interpreter or Node. When HHVM runs your PHP code, its behavior should be identical to running it on the PHP5 engine from php.net, the...
HHVM non-deterministic behaviour of the typechecker
You are probably using an outdated version of HHVM. This problem sounds an awful lot like this race condition, which was fixed in HHVM 3.5.0 and newer (and was backported into the 3.3.3 LTS release). Notably, 3.4.x still had the bug. What version of HHVM are you using?...
array_merge for Maps and Vectors at hacklang
Answering to my self. In fact array_merge is not listed under the list of functions with support for hack Collections. The best way to merge Vectors is the function addAll. <?hh $a = Vector {"qux"}; $b = Vector {"foo","bar"}; $a->addAll($b); var_dump($a); In the case of Map, it's a bit more...
HHVM outputs status code 200 on fatal errors and I can't use fastcgi_next_upstream because of that
wordpress,nginx,fastcgi,fatal-error,hhvm
I fixed this by injecting custom error handler for hhvm. My index.php for wordpress: <?php /** * HHVM outputs http status: 200 OK even on fatal errors. * Catch fatal errors on HHVM and put right response code. */ //Is this HHVM? if (defined('HHVM_VERSION')) { set_error_handler('catch_fatal_error_hhvm',E_ERROR); } function catch_fatal_error_hhvm() {...

How do you format the HHVM error log output?
This is currently hardcoded in hhvm's source. I highly recommend submitting a feature request to the hhvm team, they're a bunch of very helpful people. If you're not interested in that, you could pretty easily edit the timestamp call to include the offset, then rearrange the snprintf() lines to match...
Stack overflow using hhvm for benchmarkgame adapted to strict Hack

Your recursion will never hit a base case and stop as the values you're passing down while recursing will never be null. You probably want to exit if $depth is 0 as well as if it is null....
Is it possible to hide sources under HHVM?
obfuscation,hhvm,code-security
@paulbliss: You could compile a bytecode repository and run that, but it's not something that would be difficult to reverse engineer. ... There isn't any great documentation on building repos. The wrapper script in tools/hhvm_wrapper.php has some useful shortcuts, you can look at the help options. There really isn't a...
I can not run HHVM on CentOS
Where is your HHVM pid file configured to live? In /etc/hhvm/server.hdf or similar, do you have a PidFile = setting? I set mine to PidFile = /var/run/hhvm/pid. I then did a mkdir /var/run/hhvm....
Disable typechecking from .hhconfig
This is not supported. A Hack project is designed to be checked as a single project, with full analysis going across all of the different parts of it. If it doesn't typecheck as a whole, then the behavior of HHVM on it is undefined. You should really, really carefully consider...
Laravel 4.2 SuperClosure: Attempted to serialize unserializable builtin class Closure
Turns out that happens if you try to serialize an Exception. (In this case, outputting it via Log::error("...", [$e]). Just stringify it and all is good.
Fatal error: f_imageloadfont is not supported: NYI in HHVM
The main part here is imageloadfont is not supported, which means calling it will cause a fatal error like the one you're seeing. You could open an issue about it to see if it can be implemented, or if the HNI definition can be removed so that a function_exists for...
Add Elements to nullable Vector
arrays,vector,nullable,hhvm,hacklang
The easiest way would be to not use a nullable Vector. private Vector<string> $lines = Vector {}; gets around the need for a constructor too. Otherwise, you'll need to check if the value isn't null, then append to it: public function addLine(string $line): void { $vec = $this->lines; if ($vec...
Execute Hackificator From PHP
This means that hh_client executable was called and returned something other than "No errors!".
phpinfo() not working correctly in HHVM
No, this is correct. HHVM doesn't output anything yet than "HipHop". This was already reported 2010. https://github.com/facebook/hhvm/issues/172 https://github.com/facebook/hhvm/issues/1038 You could use this to see what your configuration is https://gist.github.com/ck-on/67ca91f0310a695ceb65...
Change the value of a lexically scoped variable in a HHVM/Hack lambda expression?
lambda,closures,hhvm,lexical-scope,hacklang
Unfortunately Hack lambda expressions do not support this. However you can still fall back on PHP 5.3 closure syntax. function allTrue(Map<string, bool> $map): bool { $valid = 1; $map->map(function ($a) use (&$valid) { $valid &= $a; }); return $valid === 1; } $map = Map{'foo' => true, 'bar' => false...
preg_replace() /e modifier is deprecated for HHVM
You can try to use the sf 1.5. version maintained by guys from L'Express: https://github.com/LExpress/symfony1 (they have fixed the problem) If their changes are too much you can check how they managed to solve the 'e modifier' problem and copy their solution.

Running hh_client on one file hangs forever
This might be a known problem: can you do killall -9 hh_server; export USER=$(logname) before trying again? If that fixes it, you've hit an issue I just fixed this week in https://github.com/facebook/hhvm/commit/53b4d9b1ad7ccf99ef7b80d5d673f1578c9791c8. That fix should be in the latest nightly build, so if you update your build, that might fix...

What is the equivalent of http_get in hhvm?
Functions like this marked as missing in HHVM are usually because the function is part of an extension that hasn't been implemented yet. The PHP.net docs say it's part of a PECL extension, pecl_http -- which doesn't look to be on by default even in PHP5 (although of course it...
Libboost dependencies on Ubuntu 14.04 during HHVM install

What will happen if we use unsupported php in hhvm?
The code will not work. The JIT isn't an addition to an existing PHP implementation. HHVM is a completely separate implementation, including differences in what will and won't run.
HHVM not compiling JWT library as expected
HHVM can't optimize code running at the top level (i.e., outside a function) very well. In the first example, most of the work is happening outside a function -- the "work" is the $sum += $i. Moving that into a function, your second example, allows HHVM to optimize it pretty...
HHVM + NGinx Connection refused
I just realized the problem by myself. HHVM with its default setting without specifying the IP to listen, was only listening ipv6 addresses. Because of that i could connect with localhost but not with 127.0.0.1 Specifying the IP by hhvm.server.ip = 127.0.0.1 solved the problem....
HHVM staticly typing lookup tables and keeping them fully cached in RAM
