5 | NOTES ON COPYRIGHTS AND LICENSES |
6 | ||
7 | Some terminology: | |
8 | ||
9 | A "copyright notice" consists of one or a few lines of this format: | |
10 | "Copyright (C) 2006, 2007 Free Software Foundation, Inc." | |
11 | ||
12 | A "license notice" is a statement of permissions, and is usually much | |
13 | longer, eg the text "GNU Emacs is free software...". | |
14 | ||
15 | ||
71428fe7 GM |
16 | Summary for the impatient: |
17 | ||
a4734fbd | 18 | 1. Don't add code to Emacs written by someone other than yourself |
c6fe6289 GM |
19 | without thinking about the legal aspect. Even if the changes are |
20 | trivial, consider if they combine with previous changes by the same | |
21 | author to make a non-trivial total. If so, make sure they have an | |
22 | assignment. If adding a whole file adjust the copyright statements in | |
23 | the file. | |
24 | ||
25 | 2. When installing code written by someone else, the ChangeLog entry | |
26 | should be in the name of the author of the code, not the person who | |
27 | installs it. I think it is helpful to put the author (if not yourself) | |
28 | in the CVS log as well; and to not install any of your own changes in | |
29 | the same commit. | |
a4734fbd GM |
30 | |
31 | 3. With images, add the legal info to a README file in the directory | |
71428fe7 GM |
32 | containing the image. |
33 | ||
a4734fbd | 34 | 4. If you add a lot of text to a previously trivial file that had no |
71428fe7 GM |
35 | legal notices, consider if you should add a copyright statement. |
36 | ||
a4734fbd | 37 | 5. Please don't just add an FSF copyright without checking that is the |
f199f76c GM |
38 | right thing to do. |
39 | ||
71428fe7 | 40 | |
571975c0 GM |
41 | Every non-trivial file distributed through the Emacs CVS should be |
42 | self-explanatory in terms of copyright and license. This includes | |
43 | files that are not distributed in Emacs releases (for example, the | |
44 | admin/ directory), because the whole Emacs CVS is publicly | |
45 | available. | |
46 | ||
47 | The definition of triviality is a little vague, but a rule of thumb is | |
48 | that any file with less than 15 lines of actual content is trivial. If | |
49 | a file is auto-generated (eg ldefs-boot.el) from another one in the | |
50 | CVS, then it does not really matter about adding a copyright statement | |
51 | to the generated file. | |
52 | ||
d502a3da GM |
53 | Legal advice says that we could, if we wished, put a license notice |
54 | even in trivial files, because copyright law in general looks at the | |
55 | overall work as a whole. It is not _necessary_ to do so, and rms | |
56 | prefers that we do not. This means one needs to take care that trivial | |
57 | files do not grow and become non-trivial without having a license | |
58 | added. NB consequently, if you add a lot of text to a small file, | |
59 | consider whether your changes have made the file worthy of a copyright | |
60 | notice, and if so, please add one. | |
c320d3b8 | 61 | |
9bfceb2b GM |
62 | It can be helpful to put a reminder comment at the start of a trivial |
63 | file, eg: "add a license notice if this grows to > 10 lines of code". | |
64 | ||
571975c0 GM |
65 | The years in the copyright notice should be updated every year (see |
66 | file "years" in this directory). The PS versions of refcards etc | |
67 | should display copyright notices (an exception to the rule about | |
68 | "generated" files), but these can just display the latest year. The | |
69 | full list of years should be kept in comments in the source file. If | |
70 | these are distributed in CVS, check in a regenerated version when the | |
71 | tex files are updated. | |
72 | ||
73 | Copyright changes should be propagated to any associated repositories | |
74 | (eg Gnus, MH-E), but I think in every case this happens automatically | |
75 | (?). | |
76 | ||
e3e14128 GM |
77 | All README (and other such text files) that are non-trivial should |
78 | contain copyright statements and GPL license notices, exactly as .el | |
bf5e9393 | 79 | files do (see e.g. README in the top-level directory). Before 2007, |
e3e14128 GM |
80 | we used a simple, short statement permitting copying and modification |
81 | provided legal notices were retained. In Feb 2007 we switched to the | |
bf5e9393 GM |
82 | standard GPL text, on legal advice. Some older text files in etc/ |
83 | should, however, keep their current licenses (see below for list). | |
571975c0 | 84 | |
e3e14128 GM |
85 | For image files, the copyright and license details should be recorded |
86 | in a README file in each directory with images. (Legal advice says | |
87 | that we need not add notices to each image file individually, if they | |
5aa27cc9 GM |
88 | allow for that.). It is recommended to use the word "convert" to |
89 | describe the automatic process of changing an image from one format to | |
90 | another (http://lists.gnu.org/archive/html/emacs-devel/2007-02/msg00618.html). | |
91 | ||
571975c0 GM |
92 | |
93 | When installing a file with an "unusual" license (after checking first | |
94 | it is ok), put a copy of the copyright and license in the file (if | |
95 | possible. It's ok if this makes the file incompatible with its | |
96 | original format, if it can still be used by Emacs), or in a README | |
97 | file in the relevant directory. | |
98 | ||
99 | The vast majority of files are copyright FSF and distributed under the | |
100 | GPL. A few files (mainly related to language and charset support) are | |
101 | copyright AIST alone, or both AIST and FSF. (Contact Kenichi Handa | |
102 | with questions about legal issues in such files.) In all these cases, | |
103 | the copyright years in each file should be updated each year. | |
104 | ||
105 | There are some exceptions to the points in the previous paragraph, and | |
106 | these are listed below for reference, together with any files where | |
107 | the copyright needs to be updated in "unusual" ways. | |
108 | ||
109 | If you find any other such cases, please consult to check they are ok, | |
110 | and note them in this file. This includes missing copyright notices, | |
111 | and "odd" copyright holders. In most cases, individual authors should | |
112 | not appear in copyright statements. Either the copyright has been | |
113 | assigned (check copyright.list) to the FSF (in which case the original | |
114 | author should be removed and the year(s) transferred to the FSF); or | |
115 | else it is possible the file should not be in Emacs at all (please | |
116 | report!). | |
117 | ||
c14dd816 GM |
118 | Note that it seems painfully clear that one cannot rely on CVS logs, |
119 | or even ChangeLogs, for older changes. People often installed changes | |
120 | from others, without recording the true authorship. | |

198 | Copyright information is duplicated in etc/ETAGS.README. Update that |
199 | file too. | |
200 | ||
201 | Until 2007 etags.c was described as being copyright FSF and Ken Arnold. | |
202 | After some investigation in Feb 2007, then to the best of our | |
203 | knowledge we believe that the original 1984 Emacs version was based | |
204 | on the version in BSD4.2. See for example this 1985 post from Ken Arnold: | |
205 | <http://groups.google.com/group/mod.sources/browse_thread/thread/ffe5c55845a640a9> | |
206 | I have received enough requests for the current source to ctags | |
207 | to post it. Here is the latest version (what will go out with | |
208 | 4.3, modulo any bugs fixed during the beta period). It is the | |
209 | 4.2 ctags with recognition of yacc and lex tags added. | |
210 | ||
211 | See also a 1984 version of ctags (no copyright) posted to net.sources: | |
212 | <http://groups.google.com/group/net.sources/msg/a21b6c21be12a98d> | |
213 | Version of etags.c in emacs-16.56 duplicates comment typos. | |
214 | ||
215 | Accordingly, in Feb 2007 we added a 1984 copyright for the | |
216 | University of California and a revised BSD license. The terms of | |
217 | this require that the full license details be available in binary | |
018a95ed GM |
218 | distributions - hence the file etc/ETAGS.README. The fact that the |
219 | --version output just says "Copyright <year> FSF" is apparently OK | |
220 | from a legal point of view. | |
571975c0 GM |

240 | lwlib/ |
241 | rms (2007/02/17): "lwlib is not assigned to the FSF; we don't consider | |
242 | it part of Emacs. [...] Therefore non-FSF copyrights are ok in lwlib." | |
243 | ||
6b00dced GM |
244 | NB don't change the GPL version used for lwlib .c and .h files (see |
245 | below). | |
246 | ||
f199f76c GM |
247 | FSF copyrights should only appear in files which have undergone |
248 | non-trivial cumulative changes from the original versions in the Lucid | |
249 | Widget Library. NB this means that if you make non-trivial changes to | |
250 | a file with no FSF copyright, you should add one. Also, if changes are | |
251 | reverted to the extent that a file becomes basically the same as the | |
252 | original version, the FSF copyright should be removed. | |
253 | ||
254 | In my (rgm) opinion, as of Feb 2007, all the non-trivial files differ | |
255 | significantly from the original versions, with the exception of | |
256 | lwlib-Xm.h. Most of the changes that were made to this file have | |
257 | subsequently been reverted. Therefore I removed the FSF copyright from | |
258 | this file (which is arguably too trivial to merit a notice anyway). I | |
259 | added FSF copyright to the following files which did not have them | |
260 | already: Makefile.in, lwlib-Xaw.c, lwlib-int.h (borderline), | |
261 | lwlib-utils.c (borderline), lwlib.c, lwlib.h. | |
262 | ||
263 | Copyright years before the advent of public CVS in 2001 were those | |
264 | when I judged (from the CVS logs) that non-trivial amounts of change | |
265 | had taken place. I also adjusted the existing FSF years in xlwmenu.c, | |
266 | xlwmenu.h, and xlwmenuP.h on the same basis. | |
267 | ||
268 | Note that until Feb 2007, the following files in lwlib were lacking | |
269 | notices: lwlib-int.h, lwlib.h, lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h | |
270 | ||
271 | The following files did not list a Lucid copyright: xlwmenu.h, | |
272 | xlwmenuP.h. | |
273 | ||
274 | To the best of our knowledge, all the code files in lwlib were | |
275 | originally part of the Lucid Widget Library, even if they did not say | |
276 | so explicitly. For example, they were all present in Lucid Emacs 19.1 | |
277 | in 1992. The exceptions are the two Xaw files, which did not appear | |
278 | till Lucid Emacs 19.9 in 1994. The file lwlib-Xaw.h is too trivial to | |
279 | merit a copyright notice, but would presumably have the same one as | |
280 | lwlib-Xaw.c. We have been unable to find a true standalone version of | |
281 | LWL, if there was such a thing, to check definitively. | |
282 | ||
283 | To clarify the situation, in Feb 2007 we added Lucid copyrights and | |
284 | GPL notices to those files lacking either that were non-trivial, | |
285 | namely: lwlib-int.h, lwlib.h, xlwmenu.h, xlwmenuP.h. This represents | |
286 | our best understanding of the legal status of these files. We also | |
287 | clarified the notices in Makefile.in, which was originally the | |
288 | Makefile auto-generated from Lucid's Imakefile. | |
289 | ||
290 | As of Feb 2007, the following files are considered too trivial for | |
291 | notices: lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h. | |
292 | ||
6b00dced GM |
293 | The version of lwlib/ first installed in Emacs seems to be the same as |
294 | that used in Lucid Emacs 19.8 (released 6-sep-93); except the two Xaw | |
295 | files, which did not appear till Athena support was added in Lucid | |
296 | Emacs 19.9. In Lucid Emacs 19.1, all files were under GPLv1 or later, | |
297 | but by Lucid Emacs 19.8, lwlib.c and xlwmenu.c had been switched to v2 | |
298 | or later. These are the versions that were first installed in Emacs. | |
299 | So in GNU Emacs, these two files have been under v2 or later since | |
300 | 1994. | |
301 | ||
302 | It seems that it was the intention of Lucid to use v1 or later | |
303 | (excepting the two files mentioned previously); so this is the license | |
304 | we have used when adding notices to code that did not have notices | |
305 | originally. Although we have the legal right to switch to v2 or later, | |
306 | rms prefers that we do not do so. | |

312 | these files. | |

315 | oldXMenu/ | |
316 | Keep the "copyright.h" method used by X11, rather than moving the | |
317 | licenses into the files. Note that the original X10.h did not use | |
318 | copyright.h, but had an explicit notice, which we retain. | |
319 | ||
320 | If you make non-trivial changes to a file which does not have an FSF | |
321 | notice, add one and a GPL notice (as per Activate.c). If changes to a | |
322 | file are reverted such that it becomes essentially the same as the | |
323 | original X11 version, remove the FSF notice and GPL. | |
324 | ||
325 | Only the files which differ significantly from the original X11 | |
326 | versions should have FSF copyright and GPL notices. At time of writing | |
327 | (Feb 2007), this is: Activate.c, Create.c, Internal.c. I (rgm) | |
328 | established this by diff'ing the current files against those in X11R1, | |
329 | and when I found significant differences looking in the ChangeLog for | |
330 | the years they originated (the CVS logs are truncated before 1999). I | |
331 | therefore removed the FSF notices (added in 200x) from the other | |
332 | files. There are some borderline cases IMO: AddSel.c, InsSel.c, | |
333 | XMakeAssoc.c, XMenu.h. For these I erred on the side of NOT adding FSF | |
334 | notices. | |
335 | ||
336 | With regards to whether the files we have changed should have GPL | |
337 | added or not, rms says (2007-02-25, "oldXmenu issues"): | |
338 | ||
339 | It does not make much difference, because oldXmenu is obsolete | |
340 | except for use in Emacs (and it is not normally used in Emacs any | |
341 | more either). | |
342 | ||
343 | So, to make things simple, please put our changes under the GPL. | |
344 | ||
345 | insque.c had no copyright notice until 2005. The version of insque.c | |
346 | added to Emacs 1992-01-27 is essentially the same as insremque.c added | |
347 | to glic three days later by Roland McGrath, with an FSF copyright and | |
348 | GPL, but no ChangeLog entry: | |
349 | <http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/libc/misc/insremque.c?\ | |
350 | rev=1.1&cvsroot=glibc> | |
351 | To the best of his recollection, McGrath (who has a copyright | |
352 | assignment) was the author of this file (email from roland at frob.com | |
353 | to rms, 2007-02-23, "Where did insque.c come from?"). The FSF | |
354 | copyright and GPL in this file are therefore correct as far as we | |
355 | understand it. | |
356 | ||
357 | Imakefile had no legal info in Feb 2007, but was obviously based on | |
358 | the X11 version (which also had no explicit legal info). As it was | |
359 | unused, I removed it. It would have the same MIT copyright as | |
360 | Makefile.in does now. | |

382 | rms: "surely written either by me or by ESR. (If you can figure out | |
383 | which year, I can probably tell you which.) Either way, we have papers | |
384 | for it." Present in Emacs-16.56 (15-jul-85). | |

386 | etc/ulimit.hack | |
387 | Very obsolete file removed March 2007. Doesn't say who the author | |
388 | is, but web-search suggests Karl Kleinpaste, who has no Emacs | |
389 | assignment. Trivial anyway. | |

395 | lisp/term/README |
396 | - had no copyright notice till Feb 2007. ChangeLog.3 suggests it was | |
397 | written by Eric Raymond. When asked by rms on 14 Feb 2007 he said: | |
398 | ||
399 | I don't remember writing it, but it reads like my prose and I believe | |
400 | I wrote the feature(s) it's describing. So I would have been the | |
401 | likeliest person to write it. | |
402 | ||
403 | Odds are that I did, but I'm not certain. | |
404 | ||
405 | Accordingly, FSF copyright was added. | |

422 | src/acldef.h, chpdef.h, ndir.h |
423 | On legal advice from Matt Norwood, the following comment was added | |
8d54e3a1 | 424 | to these files in Feb/Mar 2007: |
1354eff6 GM |
425 | |
426 | The code here is forced by the interface, and is not subject to | |
427 | copyright, constituting the only possible expression of the | |
428 | algorithm in this format. | |
429 | ||
430 | With the addition of this notice, these files are OK for the | |
431 | upcoming Emacs-22 release. Post-release, we can revisit this issue | |
432 | and possibly add a list of all authors who have changed these files. | |
433 | (details in email from Matt Norwood to rms, 2007/02/03). | |
434 | ||
dc9332a6 GM |
435 | etc/ms-7bkermit |
436 | Says it was written by Andy Lowry and Joel Spolsky. No entry for | |
437 | either in copyright.list. NB this file is not "constrained" like | |
438 | ms-kermit (rms: "We know it isn't. A comment at the front says it has | |
439 | other bindings which might be handy."). File removed March 2007. | |
440 | Re-add if clear up status at some point. | |
441 | ||
442 | etc/Xkeymap.txt | |
443 | No info on author. File removed March 2007. rms: "It says it is | |
444 | RLK's way of remapping his keyboard, so it is not constrained. I think | |
445 | it was written by RLK. Let's delete it; if we contact RLK again, we | |
446 | can put it back." | |

450 | src/s/aix3-2.h, bsd386.h, hpux8.h, hpux9.h, irix4-0.h, irix5-0.h, | |
451 | isc2-2.h, netbsd.h, osf1.h, sol2-3.h, sunos4-0.h, usg5-4-2.h | |
452 | - all these (not obviously trivial) files were missing copyrights | |
453 | till Feb 2007, when FSF copyright was added. Matt Norwood advised: | |
454 | ||
455 | For now, I think the best policy is to assume that we do have | |
456 | assignments from the authors (I recall many of these header files | |
457 | as having been originally written by rms), and to attach an FSF | |
458 | copyright with GPL notice. We can amend this if and when we | |
459 | complete the code audit. Any additions to these files by | |
460 | non-assigned authors are arguably "de minimis" contributions to | |
461 | Emacs: small changes or suggestions to a work that are subsumed in | |
462 | the main authors' copyright in the entire work. | |
463 | ||
464 | Here is my (rgm) take on the details of the above files: | |
465 | ||
466 | mips4.h | |
467 | might be trivial? started trivial, been added to in tiny changes by | |
468 | those with FSF assignment, often result of email suggestions by others. | |
469 | ||
470 | news-risc.h | |
471 | started trivial. Grown by tiny additions, plus chunk | |
472 | from mips.h, which was and is Copyright FSF | |
473 | ||
474 | pmax.h | |
475 | started trivial. grown in tiny changes, except for maybe Jim Wilson's | |
476 | comment. | |
477 | ||
478 | ? irix4-0.h | |
479 | I would say started non-trivial (1992, rms). only tiny changes since | |
480 | installed. | |
481 | ||
482 | ? irix5-0.h | |
483 | I would say started non-trivial (1993, jimb, heavily based | |
484 | on irix4-0.h). A few borderline non-tiny changes since. | |
485 | ||
486 | ? isc2-2.h | |
487 | started trivial. 2 non-tiny change, in 1993. looks to | |
488 | be made up of several small tweaks from various sources. maybe | |
489 | non-tiny total changes from Karl Berry (no emacs assignment). | |
490 | ||
491 | osf1.h | |
492 | started trivial. grown in tiny changes (one borderline tiny change | |
493 | by fx in 2000, but most code was later removed). non-tiny addition | |
494 | in 2002 from m/alpha.h, but that was and is copyright FSF. | |
495 | ||
496 | usg5-4-2.h | |
497 | started non-trivial, but was heavily based on usg5-4.h, which was and is | |
498 | copyright FSF. only tiny changes since installed. | |
499 | ||
500 | sol2-3.h | |
501 | started trivial. only non-tiny change (1994) incorporated code from | |
502 | usg5-4.h, which was and is copyright FSF. | |
503 | ||
504 | aix3-2.h, bsd386.h, hpux8.h, hpux9.h, netbsd.h, sunos4-0.h | |
505 | started trivial, grown in tiny changes. | |
506 | ||
d502a3da GM |
507 | netbsd.h: |
508 | Roland McGrath said to rms (2007/02/17): "I don't really remember | |
509 | anything about it. If I put it in without other comment, then probably | |
510 | I wrote it myself." | |
511 | ||

6ce26337 GM |
513 | Someone might want to tweak the copyright years (for dates before |
514 | 2001) that I used in all these files. | |
515 | ||
516 | Note: erring on the side of caution, I also added notices to some | |
517 | files I thought might be considered non-trivial (if one includes | |
518 | comment) in s/: | |
519 | aix4-1.h hiuxmpp.h hiuxwe2.h hpux10.h irix6-0.h irix6-5.h isc3-0.h | |
520 | ptx4.h sol2.h sunos4-0.h | |
521 | ||
522 | (everything with > 30 non-blank lines, which at least is _some_ kind of | |
523 | system) | |

534 | Is it OK to just `cvs remove' a file for legal reasons, or is |
535 | something more drastic needed? A removed file is still available from | |

537 | not affect a release). | |
