dss/sig.c, branch maintDSS - dyadic snapshot schedulerhttps://git.tue.mpg.de/cgit/dss/atom?h=maint2015-02-25T10:39:48ZImprove signal handler.2015-02-25T10:39:48ZAndre Nollmaan@tuebingen.mpg.de2015-02-25T10:15:33Zurn:sha1:612d4cad3e8007c4c8a70181a8bc66730ae3a972
The signal handler of dss has two issues: (a) it does not check the
return value of the write(2) call, and (b) it does not restore errno
on exit. The second issue might cause problems on systems where
write(2) sets errno also on success. Those problems would be very
hard to reproduce and debug. So it is probably a good idea to be
conservative here.
This commit fixes (a) by printing an error message and calling exit(3)
if the write to the signal pipe failed or resulted in a short write.
As for (b), we now save a copy of errno before the write(2) call,
and restore the old value on success.
Change email address and URLs.2014-08-19T12:18:38ZAndre Nollmaan@tuebingen.mpg.de2014-08-16T10:00:18Zurn:sha1:8daf8f3836e745ba07f1aa01252279588574c95a
The web and email service of systemlinux.org was down for two
weeks. Meanwhile the dss web pages found a new home at the MPI campus
of Tübingen.
This commit changes the email addresses and the home page URL.

Has been cooking for several weeks. The conflicts
daemon.c
exec.c

ipc.c
sig.c
are trivial and can be resolved easily.
Rename source files which also exist as system headers.2012-08-15T09:41:32ZAndre Nollmaan@systemlinux.org2012-08-11T18:32:19Zurn:sha1:46cbddf465bd66ba1d5c4bcc780ae0d65abd7f73
As pointed out by Daniel Richard G. some of the dss header files
are named the same as system header files.
This patch renames these headers as well as their corresponding .c
files. Specifically, error.h, fd.h, signal.h, string.h and time.h
become err.h, file.h, sig.h, str.h and tv.h.
