Dear RT,
sorry to bother you again, but there is an important bug in hdapsd I'd
like to fix for jessie:
#770069 [i] [hdapsd] fails to stop without SIGKILL on FREEFALL hardware
There is a patch [1], which is currently tested by the reporter (I do not
own the needed hardware). As soon I get positive results, I'd like to
release a fix upstream and upload it to Debian.
As I will be releasing a new upstream anyways, my prefered fix for #770069
would be that very release in Debian. This would result in the following
(filtered) debdiff in hdapsd-20141202-1.debdiff:
configure.ac | 2 +-
hdapsd-20141202/debian/rules | 4 ----
hdapsd-20141202/misc/Makefile.am | 1 +
hdapsd-20141202/src/hdapsd.c | 24 +++++++++++++++++-------
4 files changed, 19 insertions(+), 12 deletions(-)
configure is the version bump, hdapsd.c is the fix.
misc/Makefile is a "make clean" fix for systemd units, which previously was
in d/rules (that's the 4 deletes in there). the files were not properly
removed before.
If you don't like the new upstream version, I could also backport the fix to
the package in jessie, which would result in the following debdiff:
hdapsd-20141024-3.debdiff
series | 1
use-sigaction-instead-of-signal.patch | 77 ++++++++++++++++++++++++++++++++++
2 files changed, 78 insertions(+)
(it's the same patch to hdapsd.c as above, plus the usual git headers).
Please tell me which way you prefer.
Thanks in advance
Evgeni
