Title:
OMSL="closed_loop" doesn't work with constant DOL
Status in EPICS Base:
New
Bug description:
This was incorrectly documented for the boRecord. I just fixed that in
the wiki.
However, I see this as yet another arbitrary limitation.
To lift that we need a small generalisation to how we treat constant
links. A constant link just has to remember whether it has been
processed before. The flag gets set by dbGetLink and the like and it
gets reset after link initialisation (so we can change the "constant"
using a CA put to the link field). If dbGetLink finds that the link is
constant, then it converts the value from the string stored in the
link, but only if it hasn't been processed before. This also means
that we can deprecate recGblInitConstantLink because it is now
subsumed by dbGetLink.
