HHVM 3.1.0 & PGSQL

hhvm, postgresql

Solution

You cannot currently load extensions into HHVM using the INI format (`hhvm.dynamic_extensions.pgsql` or `extension`). You have to use the Hdf format for this.

The easiest way to do this so that it works from both the web and the CLI is to create `/etc/hhvm/config.hdf` and add:

DynamicExtensionPath = /data/config/etc/hhvm/extensions
DynamicExtensions {
    * = pgsql.so
}

Then, edit `/etc/default/hhvm` and uncomment the `ADDITIONAL_ARGS` line and change it to `ADDITIONAL_ARGS="-c /etc/hhvm/config.hdf"`. Restart HHVM and it should then be picked up.

The CLI automatically tries to load this file, so you don't need to do anything extra there (unless you're passing in a `-c` option, then you'll need to pass in the `config.hdf` file too)

Problem

I am having issues with getting the PGSQL extension working in HHVM 3.1.0, on Ubuntu Trusty 14.04 (LTS), with NGINX. ``` #hhvm --version HipHop VM 3.1.0 (rel) Compiler: tags/HHVM-3.1.0-0-g71ecbd8fb5e94b2a008387a2b5e9a8df5c6f5c7b Repo schema: 88ae0db264d72ec2e2eb22ab25d717214aee568b ``` Following the instructions here, https://github.com/PocketRent/hhvm-pgsql I edit my /etc/hhvm/php.ini file, and add the following: ``` DynamicExtensionPath = /data/config/etc/hhvm/extensions/ DynamicExtensions { * = pgsql.so } ``` but I get an error when starting HHVM : ``` # service hhvm restart * Restarting HHVM FastCGI Daemon hhvm syntax error, unexpected JUNK, expecting $end or TC_SECTION or TC_LABEL or END_OF_LINE in /etc/hhvm/php.ini on line 13\n syntax error, unexpected JUNK, expecting $end or TC_SECTION or TC_LABEL or END_OF_LINE in /etc/hhvm/php.ini on line 13\n ``` My php.ini looks like this ``` ; php options ; hhvm specific hhvm.log.level = Warning hhvm.log.always_log_unhandled_exceptions = true hhvm.log.runtime_error_reporting_level = 8191 hhvm.mysql.typed_results = false ; hhvm.dynamicextensions.pgsql = /data/config/etc/hhvm/extensions/pgsql.so DynamicExtensionPath = /data/config/etc/hhvm/extensions/ DynamicExtensions { * = pgsql.so } ``` You can see I have also tried the following based on the info I have seen about moving from hdf to an ini file: ``` hhvm.dynamic_extensions.pgsql = /data/config/etc/hhvm/extensions/pgsql.so ``` which does not throw any errors on startup, but does not render true when running PHP code ``` if (extension_loaded('pgsql')) { ``` The pgsql.so comes from the pre-built binary here https://github.com/PocketRent/hhvm-pgsql/tree/releases/3.1.0/ubuntu/trusty, to ensure it matches the Ubunntu / HHVM version I am using. Can anyone help out here and tell me what is going on? Thanks!
