Bug#1065824: libneatvnc0: ABI break in 0.8.0 without SONAME bump
Package: libneatvnc0
Version: 0.8.0+dfsg-1
Severity: important
Justification: Policy 8.6.2
Tags: upstream
X-Debbugs-Cc: weston@packages.debian.org, wayvnc@packages.debian.org
libneatvnc 0.8.0 removes a public function from its API/ABI:
│ -const char* nvnc_client_get_hostname(const struct nvnc_client* client);
│ +int nvnc_client_get_address(const struct nvnc_client* client,
│ + struct sockaddr* restrict addr, socklen_t* restrict addrlen);
>From codesearch.debian.net, it seems that nothing in Debian actually calls
nvnc_client_get_hostname(), so perhaps this is non-RC. Normally I'd be
saying this is a decision for its maintainer, but it was recently orphaned
(in the same upload that updated it to this new upstream version, which
seems an unusual choice), so now it's a decision for whoever takes over
maintenance.
If important packages like weston are going to have dependencies on
neatvnc, then I think it would be helpful for whoever takes over this
package to teach its upstream about the two options for ABI stability
(briefly: either don't break ABI, or do break ABI but at the same time
also bump the SONAME).
