Natural sort error

[mrblackus]

Hi,

My issue looks a lot like #265.
When doing a sort $natural => -1 on a find, a Cannot use $-modifiers or empty keys in 'opts' RuntimeException is raised.

My environment is:
PHP: 7.0.12
Library: 1.0.3
Mongodb: 3.2
Extension: mongodb-1.2.0alpha3

$collection->find([], [ 'sort' => [ '$natural' => -1 ]]);

Maybe I'm doing something wrong, or is it a bug?

@mrblackus It looks like that was fixed in libmongoc 1.5.0-rc4. The current driver appears to utilize 1.5.0-rc3. You might be able to get them to bump that to rc4 if you open a ticket over at https://github.com/mongodb/mongo-php-driver/issues.

Indeed, this is also caused by CDRIVER-1692. The next extension release will bump the libmongoc version to 1.5.0-rc4 or the stable release if it's available by then. No need to open another issue on the extension repository.

Thanks for your quick answers!

@jmikola Is there a timeline for the next 1.2.0 release, or just "when ready"?

@moderndeveloperllc: 1.2.0 is tracking the MongoDB 3.4 release, as is library version 1.1.0. I don't have any hard dates, but we're getting there based on the recent server release candidates.

@mrblackus: 1.2.0 of the PHP driver has been released, which includes libmongoc 1.5.0. Please upgrade and report back if the issue is resolved.

The 1.0.3 library version is compatible with the 1.2.0 extension version, so there should be no need to upgrade the library for this issue.
