There was a problem hiding this comment.
Looks good to me!
Just to make sure I understand this correctly, this isn't specific to flags is it? The issue is that if an attribute present in the source tree was "ghosted" by a first ppx but consumed by a second one it wasn't correctly marked as seen because Attribute_table.remove wouldn't find it.
|
Out of curiosity, what was the ppx chain that lead you to this bug? |
|
You are correct that this is not specific to flags. Flags just had a test that was easy to use for this purpose. As for what lead to this, someone here at jane street was working with a ppx, and if they ghosted their locations they got an attribute not used error, but if they didn't ghost the locations they got a location check error. So it was a catch 22, and this change is needed to resolve it. |

CHANGES: - Fix `Longident.parse` so it properly handles unparenthesized dotted operators such as `+.` or `*.`. (ocaml-ppx/ppxlib#111, @rgrinberg, @NathanReb) - raising an exception does no longer cancel the whole context free phase(ocaml-ppx/ppxlib#453, @Burnleydev1) - Sort embedded errors that are appended to the AST by location so the compiler reports the one closer to the beginning of the file first. (ocaml-ppx/ppxlib#463, @NathanReb) - Update `Attribute.get` to ignore `loc_ghost`. (ocaml-ppx/ppxlib#460, @ceastlund) - Add API to manipulate attributes that are used as flags (ocaml-ppx/ppxlib#408, @dianaoigo) - Update changelog to use ISO 8061 date format: YYYY-MM-DD. (ocaml-ppx/ppxlib#445, @ceastlund) - Replace `Caml` with `Stdlib`. (ocaml-ppx/ppxlib#427, @ceastlund) - When a transformation raises, the last valid AST is used as input to the upcoming transformations. All such errors are collected and appended as extension nodes to the final AST (ocaml-ppx/ppxlib#447, @Burnleydev1) - Fix a small mistake in the man pages: Embededding errors is done by default with `-as-pp`, not with `-dump-ast` (ocaml-ppx/ppxlib#464, @pitag-ha) - Set appropriate binary mode when writing to `stdout` especially for Windows compatibility. (ocaml-ppx/ppxlib#466, @jonahbeckford)

Attribute.getandAttribute.has_flagto ignoreloc_ghostfield of attribute locations. This allows flags to be used in code that is manipulated by other ppxes and hasloc_ghostset tofalsealong the way, when the original attribute in the source file hadloc_ghostset totrue.The diff to the tests is probably slightly more readable commit-by-commit.
