Hi,

I have seen that dbGetFieldType() and dbGetLinkType() are about to be

removed. What is the replacement for dbGetLinkType()? I want to find out

if a field is a PV link.

I use it in a utility function "dbll" (database list links) to show

which records link to given records or field: dbll recordpattern[.field]

The core of the function is:

 for (status = dbFirstRecordType(&dbEntry); !status; status =

dbNextRecordType(&dbEntry))

 for (status = dbFirstRecord(&dbEntry); !status; status =

dbNextRecord(&dbEntry))

    {
#if EPICS_VERSION*10000+EPICS_REVISION*100+EPICS_MODIFICATION >= 31411
        if (dbIsAlias(&dbEntry)) continue;
#endif

 for (status = dbFirstField(&dbEntry, 0); !status; status =

dbNextField(&dbEntry, 0))

        {
            if (dbGetLinkType(&dbEntry) == DCT_LINK_PV)
            {

 const char* target = ((DBLINK

*)dbEntry.pfield)->value.pv_link.pvname;

                if (!match || (
                        (strchr(target, '.') ? 1 : 0) == (d ? 1 : 0) ?
                            epicsStrGlobMatch(target, match) :

 alt_match ? epicsStrGlobMatch(target,

alt_match) : 0))

                {

 printf("%s.%s ==> %s\n", dbGetRecordName(&dbEntry),

dbGetFieldName(&dbEntry),

                        dbGetString(&dbEntry));
                }
            }
        }
    }
    dbFinishEntry(&dbEntry);

All,

We're planning to make a minor release of Base ahead of the core dev. meeting
at SLAC in 2 weeks.  Hopefully early next week.  The intent is to release the
bug fixes which have accumulated since 7.0.2 in December before we merge more
extensive changes during the meeting.

This mail is a call for testers and Base module owners to commit/submit any
fixes already known.

Michael

The outstanding un-merged fixes I'm aware of which may meet this criteria are:

https://bugs.launchpad.net/epics-base/+bug/1812084

https://github.com/epics-base/epics-base/pull/24

The fixes which have been committed should be listed in the module release notes.

No changes have been made to pvaClient and pvDatabase since 7.0.2
