Support for info fields is now done:
https://code.launchpad.net/~dirk.zimoch/epics-base/+git/epics-base/+ref/info_fields
To list info fields it has the shell function
dbli [pattern...]
You can read info fields with channel access
caget record.info
caget record.info$
... or with db methods
dbgf record.info
... which automatically allows links
field(INP, "record.info")
Access is read-only at the moment
Now I would like to add tests. Is there already support to compare shell
function output with expected output?
Where to put the test? I want to test the shell function as well as
channel access.

I could fix the problem that infos may appear on the alias dbRecordNode,
but to allow 'caget alias.info' I needed dbRecordNode.aliasedRecnode
which Michael introduced in 3.16(?). Thus it would make sense to
implement CA to info fields in 3.16+ only, right? For my tests, I have
simple back-ported aliasedRecnode to 3.14.12.7.

One thing is a bit confusing at them moment:
When a record has infos and aliases, the infos are bound to the
previous alias, not to the original record:
record (ai, "dz:ai")
{
alias("alias1")
info(my_info_field, "Hello World")
alias("alias2")
}
alias("dz:ai","alias3")
epics> dbla
alias1 --> dz:ai
alias2 --> dz:ai
alias3 --> dz:ai
epics> dbli
alias1.my_info_field "Hello World"
$ caget dz:ai.my_info_field
Channel connect timed out: 'dz:ai.my_info_field' not found.
$ /usr/local/epics/base/bin/SL6-x86_64/caget alias1.my_info_field
alias1.my_info_field Hello World
$ /usr/local/epics/base/bin/SL6-x86_64/caget alias2.my_info_field
Channel connect timed out: 'alias2.my_info_field' not found.
$ /usr/local/epics/base/bin/SL6-x86_64/caget alias3.my_info_field
Channel connect timed out: 'alias3.my_info_field' not found.
Need to fix that...
