Couple of issues I found in sndif while preparing displif for review:
1. missing string constants
+#define XENSND_FIELD_BE_VERSIONS "versions"
+#define XENSND_FIELD_FE_VERSION "version"
2. I would like to have one more part in the state diagrams section
which is currently missing: recovery flow for the case when
backend/frontend dies:
+ *------------------------------- Recovery flow
-------------------------------
+ *
+ * In case of frontend unrecoverable errors backend handles that as
+ * if frontend goes into the XenbusStateClosed state.
+ *
+ * In case of backend unrecoverable errors frontend tries removing
+ * the emulated device. If this is possible at the moment of error,
+ * then frontend goes into the XenbusStateInitialising state and is
ready for
+ * new connection with backend. If the emulated device is still in use and
+ * cannot be removed, then frontend goes into the
XenbusStateReconfiguring state
+ * until either the emulated device removed or backend initiates a new
+ * connection. On the emulated device removal frontend goes into the
+ * XenbusStateInitialising state.
+ *
Thank you,
Oleksandr
