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; } $map = Map{'foo' => true, 'bar' => false...
Fatal error: f_imageloadfont is not supported: NYI in HHVM
The main part here is imageloadfont is not supported, which means calling it will cause a fatal error like the one you're seeing. You could open an issue about it to see if it can be implemented, or if the HNI definition can be removed so that a function_exists for...
HHVM - How to use hh_client properly
The editor bindings are probably what you want. Vim https://github.com/hhvm/vim-hack emacs https://github.com/facebook/hhvm/blob/master/hphp/hack/editor-plugins/emacs/hack-for-hiphop.el ...
Running hh_client on one file hangs forever
This might be a known problem: can you do killall -9 hh_server; export USER=$(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...
Nginx and HHVM always return a 404

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...
Libboost dependencies on Ubuntu 14.04 during HHVM install
Those instructions are for Ubuntu 13.10. 14.04 has different requirements, so you should be following the instructions for Prebuilt 14.04 packages instead.
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...
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.
Error viewing images after enabling HHVM
I figured out the problem we had where the image disappeared when we enabled HHVM from control Panel. The problem is the memory limit in the .INI file was -1 and magneto GD2.php does not recognize -1 value in memory check function in GD2.php as in the code below (LINE...
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...
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-fastcgi + nginx how to make it display fatal errors in the browser
You need to enable the configuration hhvm.server.implicit_flush in your php.ini, then you can send a response body in case of fatal errors. To be able to catch fatal errors with an error handler, you should also enable hhvm.error_handling.call_user_handler_on_fatals. For details, refer to the github issue on hhvm....

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() {...
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?...
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...

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...
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.

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(); ...
HHVM staticly typing lookup tables and keeping them fully cached in RAM
Okay I've solved my first question. I don't have any global scope issues. My require is being done from inside function main(), so it's as if the code from lookuptable####.php is being inserted into function main(). HHVM docs: "If the include occurs inside a function..." Basically if you were to...
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...

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...
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...
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...

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...
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....
