Since the Cogl 1.18 branch is actively maintained in parallel with the
master branch; this is a counter part to commit 1b83ef938fc16b which
re-licensed the master branch to use the MIT license.
This re-licensing is a follow up to the proposal that was sent to the
Cogl mailing list:
http://lists.freedesktop.org/archives/cogl/2013-December/001465.html
Note: there was a copyright assignment policy in place for Clutter (and
therefore Cogl which was part of Clutter at the time) until the 11th of
June 2010 and so we only checked the details after that point (commit
0bbf50f905)
For each file, authors were identified via this Git command:
$ git blame -p -C -C -C20 -M -M10 0bbf50f905..HEAD
We received blanket approvals for re-licensing all Red Hat and Collabora
contributions which reduced how many people needed to be contacted
individually:
- http://lists.freedesktop.org/archives/cogl/2013-December/001470.html
- http://lists.freedesktop.org/archives/cogl/2014-January/001536.html
Individual approval requests were sent to all the other identified authors
who all confirmed the re-license on the Cogl mailinglist:
http://lists.freedesktop.org/archives/cogl/2014-January
As well as updating the copyright header in all sources files, the
COPYING file has been updated to reflect the license change and also
document the other licenses used in Cogl such as the SGI Free Software
License B, version 2.0 and the 3-clause BSD license.
This patch was not simply cherry-picked from master; but the same
methodology was used to check the source files.

* @short_description: Macros for determining the version of Cogl being used
|
|
*
|
|
* Cogl offers a set of macros for checking the version of the library
|
|
* at compile time.
|
|
*
|
|
* Cogl adds version information to both API deprecations and additions;
|
|
* by definining the macros %COGL_VERSION_MIN_REQUIRED and
|
|
* %COGL_VERSION_MAX_ALLOWED, you can specify the range of Cogl versions
|
|
* whose API you want to use. Functions that were deprecated before, or
|
|
* introduced after, this range will trigger compiler warnings. For instance,
|
|
* if we define the following symbols:
|
|
*
|
|
* |[
|
|
* COGL_VERSION_MIN_REQUIRED = COGL_VERSION_1_6
|
|
* COGL_VERSION_MAX_ALLOWED = COGL_VERSION_1_8
|
|
* ]|
|
|
*
|
|
* and we have the following functions annotated in the Cogl headers:
|
|
*
|
|
* |[
|
|
* COGL_DEPRECATED_IN_1_4 void cogl_function_A (void);
|
|
* COGL_DEPRECATED_IN_1_6 void cogl_function_B (void);
|
|
* COGL_AVAILABLE_IN_1_8 void cogl_function_C (void);
|
|
* COGL_AVAILABLE_IN_1_10 void cogl_function_D (void);
|
|
* ]|
|
|
*
|
|
* then any application code using the functions above will get the output:
|
|
*
|
|
* |[
|
|
* cogl_function_A: deprecation warning
|
|
* cogl_function_B: no warning
|
|
* cogl_function_C: no warning
|
|
* cogl_function_D: symbol not available warning
|
|
* ]|
|
|
*
|
|
* It is possible to disable the compiler warnings by defining the macro
|
|
* %COGL_DISABLE_DEPRECATION_WARNINGS before including the cogl.h
|
|
* header.
