libgphobos1: ABI breakage in SRU

[Steve Langasek]

gcc-10 was a shipped as a pre-release version in focal, which saw an ABI change in libgphobos with the GCC 10.2 release. Now instead of reverting this change, just rebuild the affected packages, mostly some games implemented in D, and dub.

Validation: CHeck the autopkg tests where available, check at least one game, that it starts.

Regression potential: low, no-change rebuilds with the updated GCC 10.3.

Original report:
gcc-10 was SRUed to focal, and in the process introduced regressions caused by ABI breakage of libgphobos1.

This has manifested as failing autopkgtests of the dub package, following unrelated SRUs:

[...]
autopkgtest [13:52:44]: test run: - - - - - - - - - - stderr - - - - - - - - - -
dub: symbol lookup error: dub: undefined symbol: _D3std3net4curl4HTTP9__mixin376onSendMFNdDFAvZmZv
[...]

The symbol present in the new version of libgphobos1 is now _D3std3net4curl4HTTP9__mixin396onSendMFNdDFAvZmZv instead of _D3std3net4curl4HTTP9__mixin376onSendMFNdDFAvZmZv.

Libraries are not allowed to change ABI without changing binary package name. And for libraries built from such a core package as gcc, ABIs should be enforced at package build time to avoid such regressions.

This regression was overlooked at the time of gcc SRU because the autopkgtests for gcc uploads are special-cased to not test all reverse-dependencies; so it's incumbent on gcc to properly enforce ABI stability.

[Matthias Klose (doko)]

lowering exaggerated severity. No, ABI stability was not impacted besides for libphobos.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Won't this break any users who have built their own binaries against libgphobos1?

Yes, it will.

A proper fix for this must include upgrade handling. There are two ways to
accomplish this:

 - new libgphobos1 declares versioned Breaks: against the complete list of
   reverse-dependencies that use the old ABI; or
 - package shipping libgphobos.so.1 gets a new name such as libgphobos1final
   or libgphobos1stable or libgphobos1abi or something

I prefer the latter over the former for aesthetic reasons (including the
fact that it handles out-of-archive packages). But given the overall small
number of packages using this library (13 reverse-dependencies in focal, and
the problem went unreported by users, it was only picked up via
autopkgtests) I think the former would be acceptable in this case.

[Łukasz Zemczak (sil2100)]

So how should we proceed now? I see a set of no-change rebuilds from Matthias in the queue, but if we'd go with the second solution Steve mentioned, those will have to be rebuilt once again, right? I like the idea of us handling out-of-archive binaries, but I also don't know what the general policy is for such situations.

[Matthias Klose (doko)]

- do the no-change rebuilds
- then re-upload gcc-10 with the added breaks
