* Use PROCESS/THREAD_QUERY_LIMITED_INFORMATION where appropriateCorinna Vinschen2016-06-271-1/+2
| | | | | | | Using PROCESS/THREAD_QUERY_INFORMATION may limit the number of processes/threads we can inspect depending on their integrity level. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Switching the Cygwin DLL to LGPLv3+, dropping commercial buyout optioncygwin-2_5_2-releaseCorinna Vinschen2016-06-231-3/+0
| | | | | | | | | | | | | | Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause. Everything else stays under GPLv3+. New Linking Exception exempts resulting executables from LGPLv3 section 4. Add CONTRIBUTORS file to keep track of licensing. Remove 'Copyright Red Hat Inc' comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* sched.cc: Use PROCESS_QUERY_INFORMATION for nowCorinna Vinschen2016-06-031-2/+1
| | | | | | | | Temporarily revert to use PROCESS_QUERY_INFORMATION instead of PROCESS_QUERY_LIMITED_INFORMATION to make sure every aspect of the next release is still XP/2003 compatible. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Rewrite scheduler functions getting and setting process and thread priorityCorinna Vinschen2016-05-201-171/+172
| | | | | | | | | | | | | | | | So far the scheduler priority handling is not POSIX compatible. The priorities use a range of -14 up to +15, which means it's not clear if the POSIX-required return value of -1 in case of an error is *really* an error or just the valid priority value -1. Even more confusing, -14 is the *max* value and 15 is the *min* value. Last but not least this range doesn't match the POSIX requirement of at least 32 priority values. This patch cleans up scheduler priority handling and moves the valid priority range to 1 (min) - 32 (max). It also adds a function sched_get_thread_priority() which will help to make thread priority more POSIX-like. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
