Avoid conflicts with libc symbols in libthr jump table.

2019-07-31T19:27:20+00:00

In some corner cases of static linking and unexpected libraries order
on the linker command line, libc symbol might preempt the same libthr
symbol, in which case libthr jump table points back to libc causing
either infinite recursion or loop.  Handle all of such symbols by
using private libthr names for them, ensuring that the right pointers
are installed into the table.

General further adoption of SPDX licensing ID tags.

2017-11-20T19:49:47+00:00

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.

Use __FBSDID() for .c files from lib/libthr/thread.

WARNS level 4 cleanup.

2006-04-04T02:57:49+00:00

Import my recent 1:1 threading working. some features improved includes:

2005-04-02T01:20:00+00:00

 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.
