I didn't jump in on the discussion where Dago initially requested
feedback for the bdb packaging change , but as the bdb stuff caused
some hickups some wider discussion might help.
Just to understand the status quo:
- We do have a CSWbdb package which currently holds 4.7.x, lives in
/opt/csw/lib (/opt/csw/lib/libdb.so to be precise), and which might
get upgraded to 4.7+ sometime in the future?
- Previous CSWbdb packages (like CSWbdb44) lived within their own
/opt/csw/lib/bdb4X/ prefix and have been replaced by stub packages
containting symlinks to /opt/csw/lib/libdb.so to preserve
functionality of existing packages?
- Packages linked against previous CSWbdb packages should be changed
to link against /opt/csw/lib/libdb.so (or to a symlink named
libdb-4.7.so which is also installed by CSWbdb)?
Now that we have a "moving version" libdb.so file (plus already existing
packages linked against previous versions), the one question that comes
to my mind is ABI compatibility? Dago mentioned BDB should be ABI
backward-compatible, but i couldn't find any page actually saying so.
The only thing i found sounds a bit like the opposite :
"Berkeley DB major and minor releases may optionally include changes in
all four areas, that is, the application API, region files, database
formats, and log files may not be backward-compatible with previous
I know API != ABI, but API changes can break ABI compatibility and i
couldn't come up with a reference that guarantees ABI compatibility.
