* Lumiera source code always was copyrighted by individual contributors
* there is no entity "Lumiera.org" which holds any copyrights
* Lumiera source code is provided under the GPL Version 2+
== Explanations ==
Lumiera as a whole is distributed under Copyleft, GNU General Public License Version 2 or above.
For this to become legally effective, the ''File COPYING in the root directory is sufficient.''
The licensing header in each file is not strictly necessary, yet considered good practice;
attaching a licence notice increases the likeliness that this information is retained
in case someone extracts individual code files. However, it is not by the presence of some
text, that legally binding licensing terms become effective; rather the fact matters that a
given piece of code was provably copyrighted and published under a license. Even reformatting
the code, renaming some variables or deleting parts of the code will not alter this legal
situation, but rather creates a derivative work, which is likewise covered by the GPL!
The most relevant information in the file header is the notice regarding the
time of the first individual copyright claim. By virtue of this initial copyright,
the first author is entitled to choose the terms of licensing. All further
modifications are permitted and covered by the License. The specific wording
or format of the copyright header is not legally relevant, as long as the
intention to publish under the GPL remains clear. The extended wording was
based on a recommendation by the FSF. It can be shortened, because the full terms
of the license are provided alongside the distribution, in the file COPYING.
The WorkForce (passive worker pool) has been coded just recently,
and -- in anticipation of this refactoring -- directly against std::thread
instead of using the old framework.
...the switch is straight-forward, using the default case
...add the ability to decorate the thread-IDs with a running counter
This solution is basically equivalent to the version implemented directly,
but uses the lifecycle-Hooks available through `ThreadHookable`
to structure the code and separate the concerns better.
This largely completes the switch to the new thread-wrapper..
**the old implementation is not referenced anymore**
...after resolving the fundamental design problems,
a policy mix-in can be defined now for a thread that deletes
its own wrapper at the end of the thread-function.
Such a setup would allow for »fire-and-forget« threads, but with
wrapper and ensuring safe allocations. The prominent use case
for such a setup would be the GUI-Thread.
after all this groundwork, implementing the invocation,
capturing and hand-over of results is simple, and the
thread-wrapper classes became fairly understandable.
- relocate some code into a dedicated translation unit to reduce #includes
- actually set the thread-ID (the old implementation had only a TODO at that point)
