A development portage branch with support for ACCEPT_LICENSE |

<p>Many users wish to regulate the software they install with regards to |
333 |
|
|
licenses for various reasons <a class="footnote-reference" href="#id3" id="id1" name="id1">[1]</a>. Some want a system free of any |
334 |
|
|
software that is not OSI-approved; others are simply curious as to what |
335 |
g2boojum |
1.1 |
licenses they are implicitly accepting.</p> |
336 |
g2boojum |
1.4 |
<p>Furthermore, some software requires that a user interactively accept its |
337 |
|
|
license for its author's to consider it legally binding. This is |
338 |
|
|
currently implemented using <tt class="docutils literal"><span class="pre">eutils.eclass</span></tt>.</p> |

344 |
|
|
<p>Most ebuilds are for software which is released under a single license. |
345 |
|
|
In these cases, the current LICENSE variable can remain as is. For |
346 |
g2boojum |
1.1 |
example:</p> |
347 |
|
|
<pre class="literal-block"> |
348 |
|
|
LICENSE="single-license" |
349 |
|
|
</pre> |
350 |
g2boojum |
1.4 |
<p>However, there are several ebuilds for software which is released under |
351 |
|
|
several licenses, of which the user must accept one, some or all <a class="footnote-reference" href="#id4" id="id2" name="id2">[2]</a>. |
352 |
|
|
To complicate this, some ebuilds include optional components which fall |
353 |
g2boojum |
1.1 |
under a different license.</p> |
354 |
g2boojum |
1.4 |
<p>To accomodate these cases, LICENSE syntax should accomodate all |
355 |
|
|
functionality offered by a DEPEND string. To keep things simple, this |
356 |
g2boojum |
1.1 |
GLEP proposes that the syntax be identical. For example:</p> |
357 |
|
|
<pre class="literal-block"> |
358 |
g2boojum |
1.2 |
LICENSE="mandatory-license |
359 |

361 |
|
|
</pre> |
362 |
genone |
1.6 |
<p>License names may contain [a-zA-Z0-9] (english alphanumeric characters), |
363 |
|

_ (underscore), - (dash), . (dot) and + (plus sign).</p> |

<p>Almost all users are willing to install any software that is |

FSF-approved. Other users are willing to install any software and |
369 |
genone |

implicitly accept its license. To this end, implementations will also |
370 |
|
|
need to handle grouping of licenses.</p> |
371 |
g2boojum |
1.4 |
<p>At a minimum, there needs to be the groups <tt class="docutils literal"><span class="pre">GPL-COMPATIBLE</span></tt>, |
372 |
genone |
1.7 |
<tt class="docutils literal"><span class="pre">FSF-APPROVED</span></tt>, <tt class="docutils literal"><span class="pre">OSI-APPROVED</span></tt> and <tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt>. |
373 |
|
|
<tt class="docutils literal"><span class="pre">NON-MUST-HAVE-READ</span></tt> licenses are those that don't require manual |
374 |
g2boojum |
1.4 |
acceptance for to be considered legally binding. This is the current |
375 |
g2boojum |
1.2 |
behaviour of portage.</p> |
376 |
genone |
1.5 |
<p>These groups are defined in a new file <tt class="docutils literal"><span class="pre">license_groups</span></tt> in |
377 |
|
|
the <tt class="docutils literal"><span class="pre">profiles</span></tt> subdirectory of the tree (or overlays). |
378 |
genone |
1.6 |
Details of handling groups defined in overlays is implementation dependent.</p> |
379 |
|
|
<p>The format of this file is</p> |
380 |
genone |
1.5 |
<pre class="literal-block"> |
381 |
|
|
<groupname> <license1> <license2> ... <licenseN> |
382 |
|
|
</pre> |
383 |
|
|
<p>Also any line starting with # is ignored and may be used for comments. |
384 |
genone |
1.6 |
Group names use the same syntax as normal license names. Also license groups |
385 |
|
|
may contain other groups. |
386 |
genone |
1.5 |
License groups may not contain negated elements, so a group</p> |

<h2><a class="toc-backref" href="#id11" id="accept-license" name="accept-license">ACCEPT_LICENSE</a></h2> |
394 |
|
|
<p>This GLEP proposes that a user be able to explicitly accept or decline |
395 |
|
|
licenses by editing a new variable <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> in |
396 |
|
|
<tt class="docutils literal"><span class="pre">/etc/make.conf</span></tt>. Again, to keep things simple, the syntax should be |
397 |
g2boojum |
1.1 |
similar to that of other incrementals. For example:</p> |
398 |
|
|
<pre class="literal-block"> |
399 |
|
|
ACCEPT_LICENSE="-* accepted-license -declined-license" |
400 |
|
|
</pre> |
401 |
g2boojum |
1.4 |
<p>As an extension, <tt class="docutils literal"><span class="pre">ACCEPT_LICENSE</span></tt> must also support <a class="reference" href="#license-groups">license groups</a>. |
402 |
|
|
This GLEP proposes that the license group be prepended by the special |
403 |
|
|
character "<tt class="docutils literal"><span class="pre">@</span></tt>". For example:</p> |
404 |
g2boojum |
1.1 |
<pre class="literal-block"> |
405 |
g2boojum |
1.2 |
ACCEPT_LICENSE="-* @FSF-APPROVED" |
406 |
g2boojum |
1.1 |
</pre> |
407 |
genone |
1.5 |
<p>License groups may be negated with the result that all elements of that group |
408 |
|
|
are also negated.</p> |
409 |
genone |
1.6 |
<p>Portage will also offer a package.license facility to offer this functionality |
410 |
|
|
on a per-package base (analog to package.keywords), other implementations may |
411 |
|
|
implement such a facility differently or not at all.</p> |

<p>Past versions of this document proposed to handle license-masked packages |

like blockers, but this would be inconsistent with other visibility |

filters as well as the current blocker system (as a blocker affects two |
