  • when to drop t64 postfix from lib packages?

    From Jakub =?utf-8?B?UnXFvmnEjWth?=@21:1/5 to All on Tue Jul 29 16:10:01 2025
    Hello,

    I wonder how to proceed with libraries affected by 64bit time_t
    transition in Debian and upstream repos going forward.

    In particular, libraries of src:knot gained t64 postfix:

    Package: libdnssec9t64
    Provides: ${t64:Provides}
    Replaces: libdnssec9
    Breaks: libdnssec9 (<< ${source:Version})

    This lead to upgrade problems with upstream packages without the `t64`
    postfix so in latest upstream packages (compiled after the transition),
    I've added Conflits/Replaces to allow smooth upgrade from Debian to
    upstream packages:

    Package: libdnssec9
    Conflicts: libdnssec9t64
    Replaces: libdnssec9t64


    When should I drop t64 postfix from Debian lib packages?


    Thanks for clarifying,
    Jakub Ružička 🍥

    Only when bumping the soname.

    To expand a bit on that answer, the reason for adding the postfix was
    to make sure that existing, compiled programs that link against
    libdnssec9 do not get executed with the new library, because they will
    break every time they try to use a time_t variable (by itself or in
    a structure). That's why the 64-bit-time-t library has a different name.

    Now, when a new version of libddnssec bumps the SONAME to 10, you can
    safely package that as libdnssec10 - it will be built with 64-bit time_t
    from the start, and there will be no chance that any already-built
    program would try to link to anything called "libdnssec10" by mistake.

    Hope that helps!

    G'luck,
    Peter
