[Opendnssec-user] RE: after update

Tue Jul 16 12:42:34 UTC 2013

Hi Ondřej, Bas,

This is unfortunate.
Those symbols disappeared in 1.6.14 when addressing bugfix #459.
(https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=459)

B.t.w. I cannot reproduce myself. When I compile OpenDNSSEC 1.3.14 or
1.3.4 with ldns 1.6.11, configure detects the absence of strlcpy and
compiles and links the replacement function via libcompat.a (even though
strlcpy is also available in libldns.so.1 !). This is with gcc 4.6.3. It
would be interesting to see the output of the build process, to see
where it differs.

I am reluctant to release current trunk (actually HEAD :) as ldns-1.7.0
with soname libldns.so.2, because it still has some issues I have to
take care of. Also, next week I will be on vacation for three weeks, so
I can only properly do it (including reviews from our dev-crew) after
august 12th.

I could just take 1.6.16, modify it so it installs with soname
libldns.so.2 and release it as 1.6.17. This would resolve your issue,
but would cause problems with FreeBSD (and other ports like packaging
systems). With such systems, a version number increase in a shared
library means rebuilding everything dependent on it. This is not
automatically detected. That is quite a dramatic change for a minor
release. Even more so because FreeBSD did not have the problem in the
first place; strlcpy is provided in its libc!

Most convenient for me would be to postpone the soname bumping release
(1.7.0) until the end of August (to be on the safe side). Would that be
acceptable for you? It means that the libldns1 package may not be
updated to 1.6.14 or beyond until that time. Alternatively you could
package a patched libldns1 1.6.16 that does export the strlcpy symbol
(nasty). I have attached a patch that does just that.

I wonder if other Linux systems (fedora) have the same problem... Paul?

PS. Yes, I have also thought about only bumping soname to .so.2 when
strlcpy is absent, but that is a bit wild. Lets explore other
possibilities first...
