$pull with $lt condition on each object

[Ben Dilts]

I'm using the PHP client, and I'm trying to remove all members of the "changes" array where "idx" is less than 50.

$db->documents->update(

array(

'_id'=>$doc['_id']

),

array(

'$pull' => array(

'changes' => array(

'idx' => array(

'$lt' => 50

)

)

)

)

);

This code doesn't seem to work--worse, it makes my Apache process hang at 100% CPU until PHP times it out after 30 seconds. Anyway, how should I perform such an update?

[Ben Dilts]

Aha! Turns out I was attempting to do a $set on the same array I was trying to $pull on, which caused the hangup in Apache. Regardless, the $pull still doesn't seem to be working.

[Ben Dilts]

No, it appears that did catch all of it. Anyway, it looks like I should probably file a bug, since bad input to update() shouldn't hang up the PHP mongo client.

This executes instantly for me. Are you using lazy connections or
safe parameters?
