@@ -111,17 +111,20 @@ mechanization in Coq:
There are a number of small differences between the paper presentation
of Actris and the formalization in Coq, that are briefly discussed here.
-
**Connectives for physical ownership of channels**
-
**Connectives for physical ownership of channels**
In the paper, physical ownership of a channel is formalized using a single
connective
`(c1,c2) ↣ (vs1,vs2)`
, while the mechanization has two connectives
for the endpoints and one for connecting them, namely:
-
`chan_own γ Left vs1`
and
`chan_own γ Right vs1`
-
`is_chan N γ c1 c2`
Here,
`γ`
is a ghost name and
`N`
an invariant name. This setup is less
intuitive but gives rise to a more practical Jacobs/Piessens-style spec of
`recv`
that does not need a closing view shift (to handle the case that the
buffer is empty).

**Later modalities in primitive rules for channels**

**Later modalities in primitive rules for channels**
The primitive rules for
`send`
and
`recv`
(
`send_spec`
and
`recv_spec`
in

)
) contain three later
(
`▷`
) modalities, which are omitted for brevity's sake in the paper. These
