* 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 Xu2005-04-021-41/+48
| | | | | | | | | | | | | | | | | | | 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
* Start locking up the active and dead threads lists. The active threadsMike Makonnen2003-05-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | list is protected by a spinlock_t, but the dead list uses a pthread_mutex because it is necessary to synchronize other threads with the garbage collector thread. Lock/Unlock macros are used so it's easier to make changes to the locks in the future. The 'dead thread list' lock is intended to replace the gc mutex. This doesn't have any practical ramifications. It simply makes it clearer what the purpose of the lock is. The gc will use this lock, instead of the gc mutex, to synchronize access to the dead list with other threads. Modify _pthread_exit() to use these two new locks instead of GIANT_LOCK, and also to properly lock and protect thread state changes, especially with respect to a joining thread. The gc thread was also re-arranged to be more organized and less nested. _pthread_join() was also modified to use the thread list locks. However, locking and unlocking here needs special care because a thread could find itself in a position where it's joining an exiting thread that is waiting on the dead list lock, which this thread (joiner) holds. If the joiner doesn't take care to lock *and* unlock in the same order they (the joiner and the joinee) could deadlock against each other.
