DSS - dyadic snapshot scheduler https://git.tue.mpg.de/cgit/dss/atom?h=master 2012-08-15T09:41:32Z 2012-08-15T09:41:32Z Andre Noll maan@systemlinux.org 2012-08-11T18:32:19Z urn: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. 2012-08-15T09:32:10Z Andre Noll maan@systemlinux.org 2012-08-15T09:32:10Z urn:sha1:42451d3bbe741ebae3c8ad49aa104ae53efdbcdb The changes in this branch are an attempt to make dss compile cleanly with the more strict compiler flags (GCC 4.6 on Linux). -pedantic -fno-common -W -Wall -Wcast-align -Wformat=2 -Wpointer-arith -Wundef -Waggregate-return -Wcast-qual -Wmissing-declarations -Wnested-externs -Wstrict-prototypes This is only a first step that addresses the easier warnings. Some, like the ones stemming from the variadic macros, have yet to be fixed. * 9e6c2f Remove some debug messages. * 899f88 string.c: Fix a statement-before-declaration issue. * 83ebb4 Remove trailing commas. * 2ed0d7 snap.h: Fix HSA_ITEM. * 508350 Fix "comma after last element" warning. * 97fbf4 compare_snapshots(): Add const keyword. * b28495 Avoid per-element initializers. * 9528cf dss.c: Fix initialization of argv[]. * 4526f9 dss.c: Remove redundant const. * 2183c6 Makefile: Split CPPFLAGS.

That topic was cooking in next for a quite some time now. 2012-08-04T11:34:54Z Daniel Richard G skunk@iSKUNK.ORG 2012-08-02T17:53:12Z urn:sha1:5083502f5fbe2d2b427451aff54c0cdc1831d7c0 This changes the definition of DSS_ERRORS so that it includes the commas, and removes the comma from both definitions of DSS_ERROR. This avoids "comma after last element" warnings, which on some compilers produces an error. 2012-08-03T08:25:11Z Andre Noll maan@systemlinux.org 2012-08-03T08:25:11Z urn:sha1:2b4f4c85be13bb26a230df6669a7138d123c1a7d This inline function is unused. 2012-06-01T15:31:36Z Andre Noll maan@systemlinux.org 2010-11-13T19:51:28Z urn:sha1:492928ebe8b83c31aeca4866fef37ab07174ed9c It works as follows: Whenever a semaphore operation is performed, the PID of the process is stored in the sempid field of the semaphore. This PID can be obtained from a different process by calling semctl with the GETPID command. com_kill() first tries to acquire the lock by calling the new mutex_try_lock() function of ipc.c. In contrast to mutex_lock(), mutex_try_lock() only operates on the first semaphore in the semaphore set, leaving the sempid field of the second semaphore unchanged. If mutex_try_lock() succeeds, no running dss process is holding the lock and the kill command fails. Otherwise, some dss process is running whose PID can be obtained by calling semctl() on the second semaphore. 2010-11-06T14:14:35Z Andre Noll maan@systemlinux.org 2010-11-06T14:14:35Z urn:sha1:00c1e3fbafc6310a32bf39bbd8c36a7acee275f9 Better late than never.. 2009-07-03T15:03:39Z Andre Noll maan@systemlinux.org 2009-07-03T15:03:39Z urn:sha1:2be48c0ac582aca639003528eeae2250af42471b A bit late, but better late than never. 2008-05-12T18:29:34Z Andre Noll maan@systemlinux.org 2008-05-12T18:29:34Z urn:sha1:a6727ed6659f287eb2a4f68ac5fbf3178f40498f 2008-05-12T08:56:35Z Andre Noll maan@systemlinux.org 2008-05-12T08:56:35Z urn:sha1:00e72666c12061e55c020a706448fac5497ce940
