ODP exposes symbols outside of odp*/_odp* namespace

The following command reports several symbols that fall outside of odp namespace, but still are exported from the library. It would be good to limit ODP to proper namespace and to have such command as an additional distcheck test.

Comment 1 Bill Fischofer 2017-05-04 00:01:44 UTC
I'm not sure this is correct. You want to be looking at the .so file, not the .o files. The .o files have to have internal names visible so that these files can be linked to produce the .so. However look at the following:

nm -g libodp-linux.so

and you only see the external ODP API as visible symbols, in addition to non-ODP stuff like glibc and OpenSSL symbols that we don't control.

Comment 2 Dmitry Eremin-Solenikov 2017-05-04 08:56:14 UTC
Bill, I'm looking onto the archive (libodp-linux.a), which is a way to link ODP with an app. And archive does export those symbols, because there is no way to limit visibility with it.

Comment 3 Bill Fischofer 2017-05-04 13:30:53 UTC
So is this really a bug then? The original visibility changes were intended to cover .so files.

Comment 4 Dmitry Eremin-Solenikov 2017-05-04 13:32:09 UTC
It is a bug, because static archive exports those names. I'd suggest to just rename respective symbols.

Comment 5 Bill Fischofer 2017-06-22 14:53:10 UTC
Dmitry, can you suggest a patch to address this?

Comment 6 Bill Fischofer 2017-08-03 14:52:49 UTC
Ping to Dmitry. Is this something we still want to address?

Comment 7 Dmitry Eremin-Solenikov 2017-08-04 07:39:18 UTC
Yes, I will take a look.

Comment 8 Bill Fischofer 2017-08-17 14:40:48 UTC
PR #108 merged.

Comment 9 Dmitry Eremin-Solenikov 2017-08-17 20:42:27 UTC
Reopened. The bug is still not fully sorted. I just fixed some low-hanging fruits for now.

PR #108 resolves this (merged)

Comment 11 Dmitry Eremin-Solenikov 2017-08-31 14:46:30 UTC
Reopening again. Please verify binary before closing the issue next time.

Comment 12 Bill Fischofer 2017-09-25 19:28:27 UTC
MUSTFIX for Tiger Moth

Comment 13 Bill Fischofer 2017-11-09 15:51:45 UTC
Not critical for Tiger Moth. Can revisit this afterwards.

Comment 14 Bill Fischofer 2017-12-07 15:40:40 UTC
Ping to Dmitry. Do we still want to pursue this?

Comment 15 Bill Fischofer 2017-12-21 15:40:08 UTC
Will review as part of Tiger Moth RC2.

Comment 16 Bill Fischofer 2018-01-18 15:37:57 UTC
Ping to Dmitry. Do we still want to pursue this for Tiger Moth RC2?

Comment 17 Dmitry Eremin-Solenikov 2018-01-18 20:42:08 UTC
Did not have time yet. It requires shooting them one by one.

Comment 18 Bill Fischofer 2018-04-05 13:19:22 UTC
This is a "nice to have" that we'll look at more post-Tiger Moth.

nm by default will show all symbols. Add -g to see only external ones.
