[DEPRECTION] NCI for "raw" pointers

Description

NCI "raw" pointers use NCI without providing a signature. This was used at one time for methods. This is no longer the case, and this functionality is now completely broken.

The raw pointer interface includes:

  • set_raw_nci_ptr
  • make_raw_nci
  • set_pointer (use set_pointer_keyed_str in stead)

I've added a patch that adds a type, NativePCCMethod, to provide for the major use case of the NCI raw interface - native PMC methods which handle their own PCC.

I'll hold off on applying this until after Tuesday's release.

We're getting a test failure that appears to be related to the series of commits (roughly, r48789 to r48794) in which this deprecation item was implemented.

Result: FAIL

Now, it may very well be that the original test is now too crude to test this area adequately. t/examples/namespace.t contains this inline comment:

# cannot test the exact result, just adding one method somewhere
# changes all. Also namespaces are hashes.  And we do not gurantee any specific
# order of keys.  test the name of the 2 toplevel names,  parrot is using

So, we may need only to update the test file. Nonetheless, we have to reopen this ticket.

Thank you very much.

Looks like the example program expects that almost anything in a namespace has a usable get_string vtable. I'm not sure if this is a reasonable assumption. If it is, NativePCCMethod must provide it.

Also, it explains poorly what it does, and using a lot of unnamed registers doesn't help. Code in examples should be more clear, IMO.

follow-up: ↓ 6   Changed 11 years ago by mikehh

As I understand it the test t/examples/namespace.t just tests for the valid output of examples/namespace/namespace_dump.pir (in fact it was set up to test all examples in namespace dir, but there is only the one).

The test merely reflects the output of the example:

As the example is failing with get_string() not implemented in class 'NativePCCMethod'

We either need to implement the get_string() method in the class, or modify the example appropriately before working on fixing the test.

I've opted to modify the example. This should be fixed in r48812.
