* POSIX compliance improvements in the pthread(3) functions.Pedro F. Giffuni2018-08-181-2/+4
| | | | | | | | | | | | | | | | This basically adds makes use of the C99 restrict keyword, and also adds some 'const's to four threading functions: pthread_mutexattr_gettype(), pthread_mutexattr_getprioceiling(), pthread_mutexattr_getprotocol(), and pthread_mutex_getprioceiling. The changes are in accordance to POSIX/SUSv4-2018. Hinted by: DragonFlyBSD Relnotes: yes MFC after: 1 month Differential Revision: D16722 Notes: svn path=/head/; revision=337992
* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

* Import my recent 1:1 threading working. some features improved includes:David Xu2005-04-021-0/+128
1. fast simple type mutex. 2. __thread tls works. 3. asynchronous cancellation works ( using signal ). 4. thread synchronization is fully based on umtx, mainly, condition variable and other synchronization objects were rewritten by using umtx directly. those objects can be shared between processes via shared memory, it has to change ABI which does not happen yet. 5. default stack size is increased to 1M on 32 bits platform, 2M for 64 bits platform. As the result, some mysql super-smack benchmarks show performance is improved massivly. Okayed by: jeff, mtm, rwatson, scottl Notes: svn path=/head/; revision=144518
