Source: g2o Version: 0~20230806-4 Severity: serious Tags: patch pending Justification: library ABI skew on upgrade User: debian-...@lists.debian.org Usertags: time-t
Dear maintainer, As part of the 64-bit time_t transition required to support 32-bit architectures in 2038 and beyond (https://wiki.debian.org/ReleaseGoals/64bit-time), we have identified g2o as a source package shipping runtime libraries whose ABI either is affected by the change in size of time_t, or could not be analyzed via abi-compliance-checker (and therefore to be on the safe side we assume is affected). To ensure that inconsistent combinations of libraries with their reverse-dependencies are never installed together, it is necessary to have a library transition, which is most easily done by renaming the runtime library package. Since turning on 64-bit time_t is being handled centrally through a change to the default dpkg-buildflags (https://bugs.debian.org/1037136), it is important that libraries affected by this ABI change all be uploaded close together in time. Therefore I have prepared a 0-day NMU for g2o which will initially be uploaded to experimental if possible, then to unstable after packages have cleared binary NEW. Please find the patch for this NMU attached. If you have any concerns about this patch, please reach out ASAP. Although this package will be uploaded to experimental immediately, there will be a period of several days before we begin uploads to unstable; so if information becomes available that your package should not be included in the transition, there is time for us to amend the planned uploads. -- System Information: Debian Release: trixie/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 6.5.0-14-generic (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system)
