Please unblock package petsc
[ Reason ]
This patch closes RC Bug#987618, reported (and patch provided) by
Andreas Beckmann.
libpetsc-real3.14/libpetsc-complex3.14: Add Breaks against
lib{petsc,slepc}-{real,complex}3.10 and
libpetsc3.10-dev-{common,examples} for smoother upgrades from buster.
The libraries are not co-installable due to the libhdf5-103 ->
libhdf5-103-1 and other package renames, the -dev-* packages are
affected by the removal of unversioned python.
Breaks have been added without package version since the version
(3.10) is embedded in the package names (libpetsc*3.10*).
Hence lintian overrides are added to ignore the lintian warning
breaks-without-version in libpetsc-real3.14 and libpetsc-complex3.14
[ Impact ]
Without this patch the upgrade from buster to bullseye will not be
smooth for systems with petsc installed. Likely the administrator will need to
manually force installation of the new version of petsc in bullseye,
or manually uninstall petsc temporarily and then reinstall after
upgrade.
[ Tests ]
debci tests are passing in testing both for petsc and dependent
packages (slepc, dolfin, etc). However armhf debci tests are currently
inactive.
Andreas Beckmann has run buster->bullseye upgrade tests to check
the patch works as intended.
[ Risks ]
No code changes, only dependency relationships (Breaks) with the older
3.10 versions of petsc has been added. Hence low risk with respect to
the libraries.
The only risk is if any specific system deliberately wants to retain
petsc 3.10 alongside petsc 3.14 (the petsc package structure in
principle enables this; conservative scientific computational
applications might desire it for particular projects; the libhdf5
problem raised in Bug#987618 is an unanticipated nuisance). In this
case those systems could rebuild petsc 3.10 against the bullseye
toolchain to fix the underlying libhdf5 problem, but will be impacted
by the Breaks introduced here.
An alternative fix is to use versioned Breaks here (<= 3.10.3+dfsg1-5,
allowing local bullseye rebuilds of petsc3.10 as -5.1). But this risk
is probably low probability, and therefore the implementation released
here does not use such versioned breaks in order to ease the
readability of debian/control.
