readConcern.level Error

RaeesBhatti commented 8 years ago

I'm trying to move from mongofill to this library. I've successfully build and added HHVM driver but keep getting this error.

Fatal error: Uncaught exception 'MongoDB\\Driver\\Exception\\RuntimeException' with message 'readConcern.level must be either 'local' or 'majority'' in /site/External/mongo-php-library/src/Operation/Find.php:179
Stack trace:
#0 /site/External/mongo-php-library/src/Operation/Find.php(179): MongoDB\\Driver\\Server->executeQuery()
#1 /site/External/mongo-php-library/src/Collection.php(439): MongoDB\\Operation\\Find->execute()
#2 /site/Service/Main.hh(7): MongoDB\\Collection->find()
#3 /site/Core/Main.hh(18): Service_Main::Packages()
#4 /site/Main.hh(18): Core_Main::initialize()
#5 {main}

I'm not sure how to set default readConcern.level. Any help would be appreciated.

You can set the default readConcern on a Client, Database or Collection by passing it in as one of the options like

$myClient->selectCollection("database", "collection", ["readConcern" => new MongoDB\Driver\ReadConcern(MongoDB\Driver\ReadConcern.LOCAL)])

LOCAL is the default on the Client if you don't explicitly specify, as far as I know, but I've been using the straight up PHP version (not HHVM). If the Manager class has an invalid readConcern by default, it sounds like a problem for https://github.com/mongodb/mongo-hhvm-driver

jmikola commented 8 years ago

@raeesiqbal: Are you explicitly setting the read concern in your own code?

Would you be able to provide a small stand-alone script that reproduces this error? Additionally, a var_dump() of your Collection object would be helpful, as that should report the read concern being used by the library. If you weren't specifying your own, we default to Manager::getReadConcern() (feel free to dump that as well).

When I try to set ReadConcern explicitly as suggested by @jacqueswaller. There is this error

Fatal error: Undefined constant 'MongoDB\\Driver\\ReadConcern' in /site/Core/Main.hh on line 11

I'll try to reproduce this error in a bare minimum environment soon.

jmikola commented 8 years ago

@raeesiqbal: I'm not sure why you dumped get_class_methods('MongoDB') above, as that's a class from the legacy driver (also present in mongofill) and not related to this library or the current HHVM extension.

If I do
$client = new MongoDB\Client();
var_dump(MongoDB\Driver\Manager\getReadConcern());
It says, Fatal error: Call to undefined function MongoDB\Driver\Manager\getReadConcern() in /site/Core/Main.hh on line 16

An error makes sense in this case, as MongoDB\Driver\Manager\getReadConcern() is syntax for a getReadConcern() function within the MongoDB\Driver\Manager namespace. My suggestion was the poke inside the Collection object (or capture the array returned by __debugInfo()) and dump the manager's read concern with something like:

$debug = $collection->__debugInfo();
var_dump($debug['manager']->getReadConcern());

Okay, here is my minimum repro environment.

/var/www/mongo-test
                             main.hh
                             External/
                                            mongo-php-library/
                                            app.hdf
                                            mongodb.so
                                            require.php

main.hh

<?php
spl_autoload_register(function($Name){
  // MongoDB library
  if(substr($Name, 0, 7) !== 'MongoDB') return;
  $Path = __DIR__.'/mongo-php-library/src/'.str_replace("\\", '/', substr($Name, 8)).'.php';
  if(file_exists($Path)){
    require($Path);
  }
});

app.hdf

Server {
    Host = mongo-test
    IP = 0.0.0.0
    Port = 80

    SourceRoot = /var/www/mongo-test

    RequestTimeoutSeconds = 512
    RequestMemoryMaxBytes = 16777216

    DefaultDocument = main.hh
    ErrorDocument404 = main.hh

}
Hack {
  Lang {
    LookForTypechecker = false
  }
}
DynamicExtensions {
  mongodb = /var/www/mongo-test/External/mongodb.so
}

It produces this error.

Fatal error: Call to undefined method MongoDB\\Driver\\Manager::getReadConcern() in /var/www/mongo-test/External/mongo-php-library/src/Database.php on line 87

and when I make it

$DB = (new MongoDB\Client())->selectDatabase('mydb', ["readConcern" => new MongoDB\Driver\ReadConcern(MongoDB\Driver\ReadConcern.LOCAL)]);

It says,

Fatal error: Class undefined: MongoDB\\Driver\\ReadConcern in /var/www/mongo-test/main.hh on line 5

As funny as it is, I tried this and it worked.

$DB = (new MongoDB\Client())->selectDatabase('mydb', ["readConcern" => new MongoDB\Driver\ReadConcern('local')]);

The problem was that witht the new mongo-hhvm-driver ReadConcern has to be defined explicitly and MongoDB\Driver\ReadConcern.LOCAL was undefined. So, I explored the the mongo-hhvm-driver's source and found that MongoDB\\Driver\\ReadConcern converts the parameter to string. So, I thought that why shouldn't I provide it with a string. And I did and it worked.

This may have been related to HHVM-175, which should be included in the 1.1.0 release of that driver.
