1 | GNU AFFERO GENERAL PUBLIC LICENSE
2 | Version 3, 19 November 2007
3 |
4 | Copyright (C) 2007 Free Software Foundation, Inc.
5 | Everyone is permitted to copy and distribute verbatim copies
6 | of this license document, but changing it is not allowed.
7 |
8 | Preamble
9 |
10 | The GNU Affero General Public License is a free, copyleft license for
11 | software and other kinds of works, specifically designed to ensure
12 | cooperation with the community in the case of network server software.
13 |
14 | The licenses for most software and other practical works are designed
15 | to take away your freedom to share and change the works. By contrast,
16 | our General Public Licenses are intended to guarantee your freedom to
17 | share and change all versions of a program--to make sure it remains free
18 | software for all its users.
19 |
20 | When we speak of free software, we are referring to freedom, not
21 | price. Our General Public Licenses are designed to make sure that you
22 | have the freedom to distribute copies of free software (and charge for
23 | them if you wish), that you receive source code or can get it if you
24 | want it, that you can change the software or use pieces of it in new
25 | free programs, and that you know you can do these things.
26 |
27 | Developers that use our General Public Licenses protect your rights
28 | with two steps: (1) assert copyright on the software, and (2) offer
29 | you this License which gives you legal permission to copy, distribute
30 | and/or modify the software.
31 |
32 | A secondary benefit of defending all users' freedom is that
33 | improvements made in alternate versions of the program, if they
34 | receive widespread use, become available for other developers to
35 | incorporate. Many developers of free software are heartened and
36 | encouraged by the resulting cooperation. However, in the case of
37 | software used on network servers, this result may fail to come about.
38 | The GNU General Public License permits making a modified version and
39 | letting the public access it on a server without ever releasing its
40 | source code to the public.
41 |
42 | The GNU Affero General Public License is designed specifically to
43 | ensure that, in such cases, the modified source code becomes available
44 | to the community. It requires the operator of a network server to
45 | provide the source code of the modified version running there to the
46 | users of that server. Therefore, public use of a modified version, on
47 | a publicly accessible server, gives the public access to the source
48 | code of the modified version.
49 |
50 | An older license, called the Affero General Public License and
51 | published by Affero, was designed to accomplish similar goals. This is
52 | a different license, not a version of the Affero GPL, but Affero has
53 | released a new version of the Affero GPL which permits relicensing under
54 | this license.
55 |
56 | The precise terms and conditions for copying, distribution and
57 | modification follow.
58 |
59 | TERMS AND CONDITIONS
60 |
61 | 0. Definitions.
62 |
63 | "This License" refers to version 3 of the GNU Affero General Public License.
64 |
65 | "Copyright" also means copyright-like laws that apply to other kinds of
66 | works, such as semiconductor masks.
67 |
68 | "The Program" refers to any copyrightable work licensed under this
69 | License. Each licensee is addressed as "you". "Licensees" and
70 | "recipients" may be individuals or organizations.
71 |
72 | To "modify" a work means to copy from or adapt all or part of the work
73 | in a fashion requiring copyright permission, other than the making of an
74 | exact copy. The resulting work is called a "modified version" of the
75 | earlier work or a work "based on" the earlier work.
76 |
77 | A "covered work" means either the unmodified Program or a work based
78 | on the Program.
79 |
80 | To "propagate" a work means to do anything with it that, without
81 | permission, would make you directly or secondarily liable for
82 | infringement under applicable copyright law, except executing it on a
83 | computer or modifying a private copy. Propagation includes copying,
84 | distribution (with or without modification), making available to the
85 | public, and in some countries other activities as well.
86 |
87 | To "convey" a work means any kind of propagation that enables other
88 | parties to make or receive copies. Mere interaction with a user through
89 | a computer network, with no transfer of a copy, is not conveying.
90 |
91 | An interactive user interface displays "Appropriate Legal Notices"
92 | to the extent that it includes a convenient and prominently visible
93 | feature that (1) displays an appropriate copyright notice, and (2)
94 | tells the user that there is no warranty for the work (except to the
95 | extent that warranties are provided), that licensees may convey the
96 | work under this License, and how to view a copy of this License. If
97 | the interface presents a list of user commands or options, such as a
98 | menu, a prominent item in the list meets this criterion.
99 |
100 | 1. Source Code.
101 |
102 | The "source code" for a work means the preferred form of the work
103 | for making modifications to it. "Object code" means any non-source
104 | form of a work.
105 |
106 | A "Standard Interface" means an interface that either is an official
107 | standard defined by a recognized standards body, or, in the case of
108 | interfaces specified for a particular programming language, one that
109 | is widely used among developers working in that language.
110 |
111 | The "System Libraries" of an executable work include anything, other
112 | than the work as a whole, that (a) is included in the normal form of
113 | packaging a Major Component, but which is not part of that Major
114 | Component, and (b) serves only to enable use of the work with that
115 | Major Component, or to implement a Standard Interface for which an
116 | implementation is available to the public in source code form. A
117 | "Major Component", in this context, means a major essential component
118 | (kernel, window system, and so on) of the specific operating system
119 | (if any) on which the executable work runs, or a compiler used to
120 | produce the work, or an object code interpreter used to run it.
121 |
122 | The "Corresponding Source" for a work in object code form means all
123 | the source code needed to generate, install, and (for an executable
124 | work) run the object code and to modify the work, including scripts to
125 | control those activities. However, it does not include the work's
126 | System Libraries, or general-purpose tools or generally available free
127 | programs which are used unmodified in performing those activities but
128 | which are not part of the work. For example, Corresponding Source
129 | includes interface definition files associated with source files for
130 | the work, and the source code for shared libraries and dynamically
131 | linked subprograms that the work is specifically designed to require,
132 | such as by intimate data communication or control flow between those
133 | subprograms and other parts of the work.
134 |
135 | The Corresponding Source need not include anything that users
136 | can regenerate automatically from other parts of the Corresponding
137 | Source.
138 |
139 | The Corresponding Source for a work in source code form is that
140 | same work.
141 |
142 | 2. Basic Permissions.
143 |
144 | All rights granted under this License are granted for the term of
145 | copyright on the Program, and are irrevocable provided the stated
146 | conditions are met. This License explicitly affirms your unlimited
147 | permission to run the unmodified Program. The output from running a
148 | covered work is covered by this License only if the output, given its
149 | content, constitutes a covered work. This License acknowledges your
150 | rights of fair use or other equivalent, as provided by copyright law.
151 |
152 | You may make, run and propagate covered works that you do not
153 | convey, without conditions so long as your license otherwise remains
154 | in force. You may convey covered works to others for the sole purpose
155 | of having them make modifications exclusively for you, or provide you
156 | with facilities for running those works, provided that you comply with
157 | the terms of this License in conveying all material for which you do
158 | not control copyright. Those thus making or running the covered works
159 | for you must do so exclusively on your behalf, under your direction
160 | and control, on terms that prohibit them from making any copies of
161 | your copyrighted material outside their relationship with you.
162 |
163 | Conveying under any other circumstances is permitted solely under
164 | the conditions stated below. Sublicensing is not allowed; section 10
165 | makes it unnecessary.
166 |
167 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
168 |
169 | No covered work shall be deemed part of an effective technological
170 | measure under any applicable law fulfilling obligations under article
171 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
172 | similar laws prohibiting or restricting circumvention of such
173 | measures.
174 |
175 | When you convey a covered work, you waive any legal power to forbid
176 | circumvention of technological measures to the extent such circumvention
177 | is effected by exercising rights under this License with respect to
178 | the covered work, and you disclaim any intention to limit operation or
179 | modification of the work as a means of enforcing, against the work's
180 | users, your or third parties' legal rights to forbid circumvention of
181 | technological measures.
182 |
183 | 4. Conveying Verbatim Copies.
184 |
185 | You may convey verbatim copies of the Program's source code as you
186 | receive it, in any medium, provided that you conspicuously and
187 | appropriately publish on each copy an appropriate copyright notice;
188 | keep intact all notices stating that this License and any
189 | non-permissive terms added in accord with section 7 apply to the code;
190 | keep intact all notices of the absence of any warranty; and give all
191 | recipients a copy of this License along with the Program.
192 |
193 | You may charge any price or no price for each copy that you convey,
194 | and you may offer support or warranty protection for a fee.
195 |
196 | 5. Conveying Modified Source Versions.
197 |
198 | You may convey a work based on the Program, or the modifications to
199 | produce it from the Program, in the form of source code under the
200 | terms of section 4, provided that you also meet all of these conditions:
201 |
202 | a) The work must carry prominent notices stating that you modified
203 | it, and giving a relevant date.
204 |
205 | b) The work must carry prominent notices stating that it is
206 | released under this License and any conditions added under section
207 | 7. This requirement modifies the requirement in section 4 to
208 | "keep intact all notices".
209 |
210 | c) You must license the entire work, as a whole, under this
211 | License to anyone who comes into possession of a copy. This
212 | License will therefore apply, along with any applicable section 7
213 | additional terms, to the whole of the work, and all its parts,
214 | regardless of how they are packaged. This License gives no
215 | permission to license the work in any other way, but it does not
216 | invalidate such permission if you have separately received it.
217 |
218 | d) If the work has interactive user interfaces, each must display
219 | Appropriate Legal Notices; however, if the Program has interactive
220 | interfaces that do not display Appropriate Legal Notices, your
221 | work need not make them do so.
222 |
223 | A compilation of a covered work with other separate and independent
224 | works, which are not by their nature extensions of the covered work,
225 | and which are not combined with it such as to form a larger program,
226 | in or on a volume of a storage or distribution medium, is called an
227 | "aggregate" if the compilation and its resulting copyright are not
228 | used to limit the access or legal rights of the compilation's users
229 | beyond what the individual works permit. Inclusion of a covered work
230 | in an aggregate does not cause this License to apply to the other
231 | parts of the aggregate.
232 |
233 | 6. Conveying Non-Source Forms.
234 |
235 | You may convey a covered work in object code form under the terms
236 | of sections 4 and 5, provided that you also convey the
237 | machine-readable Corresponding Source under the terms of this License,
238 | in one of these ways:
239 |
240 | a) Convey the object code in, or embodied in, a physical product
241 | (including a physical distribution medium), accompanied by the
242 | Corresponding Source fixed on a durable physical medium
243 | customarily used for software interchange.
244 |
245 | b) Convey the object code in, or embodied in, a physical product
246 | (including a physical distribution medium), accompanied by a
247 | written offer, valid for at least three years and valid for as
248 | long as you offer spare parts or customer support for that product
249 | model, to give anyone who possesses the object code either (1) a
250 | copy of the Corresponding Source for all the software in the
251 | product that is covered by this License, on a durable physical
252 | medium customarily used for software interchange, for a price no
253 | more than your reasonable cost of physically performing this
254 | conveying of source, or (2) access to copy the
255 | Corresponding Source from a network server at no charge.
256 |
257 | c) Convey individual copies of the object code with a copy of the
258 | written offer to provide the Corresponding Source. This
259 | alternative is allowed only occasionally and noncommercially, and
260 | only if you received the object code with such an offer, in accord
261 | with subsection 6b.
262 |
263 | d) Convey the object code by offering access from a designated
264 | place (gratis or for a charge), and offer equivalent access to the
265 | Corresponding Source in the same way through the same place at no
266 | further charge. You need not require recipients to copy the
267 | Corresponding Source along with the object code. If the place to
268 | copy the object code is a network server, the Corresponding Source
269 | may be on a different server (operated by you or a third party)
270 | that supports equivalent copying facilities, provided you maintain
271 | clear directions next to the object code saying where to find the
272 | Corresponding Source. Regardless of what server hosts the
273 | Corresponding Source, you remain obligated to ensure that it is
274 | available for as long as needed to satisfy these requirements.
275 |
276 | e) Convey the object code using peer-to-peer transmission, provided
277 | you inform other peers where the object code and Corresponding
278 | Source of the work are being offered to the general public at no
279 | charge under subsection 6d.
280 |
281 | A separable portion of the object code, whose source code is excluded
282 | from the Corresponding Source as a System Library, need not be
283 | included in conveying the object code work.
284 |
285 | A "User Product" is either (1) a "consumer product", which means any
286 | tangible personal property which is normally used for personal, family,
287 | or household purposes, or (2) anything designed or sold for incorporation
288 | into a dwelling. In determining whether a product is a consumer product,
289 | doubtful cases shall be resolved in favor of coverage. For a particular
290 | product received by a particular user, "normally used" refers to a
291 | typical or common use of that class of product, regardless of the status
292 | of the particular user or of the way in which the particular user
293 | actually uses, or expects or is expected to use, the product. A product
294 | is a consumer product regardless of whether the product has substantial
295 | commercial, industrial or non-consumer uses, unless such uses represent
296 | the only significant mode of use of the product.
297 |
298 | "Installation Information" for a User Product means any methods,
299 | procedures, authorization keys, or other information required to install
300 | and execute modified versions of a covered work in that User Product from
301 | a modified version of its Corresponding Source. The information must
302 | suffice to ensure that the continued functioning of the modified object
303 | code is in no case prevented or interfered with solely because
304 | modification has been made.
305 |
306 | If you convey an object code work under this section in, or with, or
307 | specifically for use in, a User Product, and the conveying occurs as
308 | part of a transaction in which the right of possession and use of the
309 | User Product is transferred to the recipient in perpetuity or for a
310 | fixed term (regardless of how the transaction is characterized), the
311 | Corresponding Source conveyed under this section must be accompanied
312 | by the Installation Information. But this requirement does not apply
313 | if neither you nor any third party retains the ability to install
314 | modified object code on the User Product (for example, the work has
315 | been installed in ROM).
316 |
317 | The requirement to provide Installation Information does not include a
318 | requirement to continue to provide support service, warranty, or updates
319 | for a work that has been modified or installed by the recipient, or for
320 | the User Product in which it has been modified or installed. Access to a
321 | network may be denied when the modification itself materially and
322 | adversely affects the operation of the network or violates the rules and
323 | protocols for communication across the network.
324 |
325 | Corresponding Source conveyed, and Installation Information provided,
326 | in accord with this section must be in a format that is publicly
327 | documented (and with an implementation available to the public in
328 | source code form), and must require no special password or key for
329 | unpacking, reading or copying.
330 |
331 | 7. Additional Terms.
332 |
333 | "Additional permissions" are terms that supplement the terms of this
334 | License by making exceptions from one or more of its conditions.
335 | Additional permissions that are applicable to the entire Program shall
336 | be treated as though they were included in this License, to the extent
337 | that they are valid under applicable law. If additional permissions
338 | apply only to part of the Program, that part may be used separately
339 | under those permissions, but the entire Program remains governed by
340 | this License without regard to the additional permissions.
341 |
342 | When you convey a copy of a covered work, you may at your option
343 | remove any additional permissions from that copy, or from any part of
344 | it. (Additional permissions may be written to require their own
345 | removal in certain cases when you modify the work.) You may place
346 | additional permissions on material, added by you to a covered work,
347 | for which you have or can give appropriate copyright permission.
348 |
349 | Notwithstanding any other provision of this License, for material you
350 | add to a covered work, you may (if authorized by the copyright holders of
351 | that material) supplement the terms of this License with terms:
352 |
353 | a) Disclaiming warranty or limiting liability differently from the
354 | terms of sections 15 and 16 of this License; or
355 |
356 | b) Requiring preservation of specified reasonable legal notices or
357 | author attributions in that material or in the Appropriate Legal
358 | Notices displayed by works containing it; or
359 |
360 | c) Prohibiting misrepresentation of the origin of that material, or
361 | requiring that modified versions of such material be marked in
362 | reasonable ways as different from the original version; or
363 |
364 | d) Limiting the use for publicity purposes of names of licensors or
365 | authors of the material; or
366 |
367 | e) Declining to grant rights under trademark law for use of some
368 | trade names, trademarks, or service marks; or
369 |
370 | f) Requiring indemnification of licensors and authors of that
371 | material by anyone who conveys the material (or modified versions of
372 | it) with contractual assumptions of liability to the recipient, for
373 | any liability that these contractual assumptions directly impose on
374 | those licensors and authors.
375 |
376 | All other non-permissive additional terms are considered "further
377 | restrictions" within the meaning of section 10. If the Program as you
378 | received it, or any part of it, contains a notice stating that it is
379 | governed by this License along with a term that is a further
380 | restriction, you may remove that term. If a license document contains
381 | a further restriction but permits relicensing or conveying under this
382 | License, you may add to a covered work material governed by the terms
383 | of that license document, provided that the further restriction does
384 | not survive such relicensing or conveying.
385 |
386 | If you add terms to a covered work in accord with this section, you
387 | must place, in the relevant source files, a statement of the
388 | additional terms that apply to those files, or a notice indicating
389 | where to find the applicable terms.
390 |
391 | Additional terms, permissive or non-permissive, may be stated in the
392 | form of a separately written license, or stated as exceptions;
393 | the above requirements apply either way.
394 |
395 | 8. Termination.
396 |
397 | You may not propagate or modify a covered work except as expressly
398 | provided under this License. Any attempt otherwise to propagate or
399 | modify it is void, and will automatically terminate your rights under
400 | this License (including any patent licenses granted under the third
401 | paragraph of section 11).
402 |
403 | However, if you cease all violation of this License, then your
404 | license from a particular copyright holder is reinstated (a)
405 | provisionally, unless and until the copyright holder explicitly and
406 | finally terminates your license, and (b) permanently, if the copyright
407 | holder fails to notify you of the violation by some reasonable means
408 | prior to 60 days after the cessation.
409 |
410 | Moreover, your license from a particular copyright holder is
411 | reinstated permanently if the copyright holder notifies you of the
412 | violation by some reasonable means, this is the first time you have
413 | received notice of violation of this License (for any work) from that
414 | copyright holder, and you cure the violation prior to 30 days after
415 | your receipt of the notice.
416 |
417 | Termination of your rights under this section does not terminate the
418 | licenses of parties who have received copies or rights from you under
419 | this License. If your rights have been terminated and not permanently
420 | reinstated, you do not qualify to receive new licenses for the same
421 | material under section 10.
422 |
423 | 9. Acceptance Not Required for Having Copies.
424 |
425 | You are not required to accept this License in order to receive or
426 | run a copy of the Program. Ancillary propagation of a covered work
427 | occurring solely as a consequence of using peer-to-peer transmission
428 | to receive a copy likewise does not require acceptance. However,
429 | nothing other than this License grants you permission to propagate or
430 | modify any covered work. These actions infringe copyright if you do
431 | not accept this License. Therefore, by modifying or propagating a
432 | covered work, you indicate your acceptance of this License to do so.
433 |
434 | 10. Automatic Licensing of Downstream Recipients.
435 |
436 | Each time you convey a covered work, the recipient automatically
437 | receives a license from the original licensors, to run, modify and
438 | propagate that work, subject to this License. You are not responsible
439 | for enforcing compliance by third parties with this License.
440 |
441 | An "entity transaction" is a transaction transferring control of an
442 | organization, or substantially all assets of one, or subdividing an
443 | organization, or merging organizations. If propagation of a covered
444 | work results from an entity transaction, each party to that
445 | transaction who receives a copy of the work also receives whatever
446 | licenses to the work the party's predecessor in interest had or could
447 | give under the previous paragraph, plus a right to possession of the
448 | Corresponding Source of the work from the predecessor in interest, if
449 | the predecessor has it or can get it with reasonable efforts.
450 |
451 | You may not impose any further restrictions on the exercise of the
452 | rights granted or affirmed under this License. For example, you may
453 | not impose a license fee, royalty, or other charge for exercise of
454 | rights granted under this License, and you may not initiate litigation
455 | (including a cross-claim or counterclaim in a lawsuit) alleging that
456 | any patent claim is infringed by making, using, selling, offering for
457 | sale, or importing the Program or any portion of it.
458 |
459 | 11. Patents.
460 |
461 | A "contributor" is a copyright holder who authorizes use under this
462 | License of the Program or a work on which the Program is based. The
463 | work thus licensed is called the contributor's "contributor version".
464 |
465 | A contributor's "essential patent claims" are all patent claims
466 | owned or controlled by the contributor, whether already acquired or
467 | hereafter acquired, that would be infringed by some manner, permitted
468 | by this License, of making, using, or selling its contributor version,
469 | but do not include claims that would be infringed only as a
470 | consequence of further modification of the contributor version. For
471 | purposes of this definition, "control" includes the right to grant
472 | patent sublicenses in a manner consistent with the requirements of
473 | this License.
474 |
475 | Each contributor grants you a non-exclusive, worldwide, royalty-free
476 | patent license under the contributor's essential patent claims, to
477 | make, use, sell, offer for sale, import and otherwise run, modify and
478 | propagate the contents of its contributor version.
479 |
480 | In the following three paragraphs, a "patent license" is any express
481 | agreement or commitment, however denominated, not to enforce a patent
482 | (such as an express permission to practice a patent or covenant not to
483 | sue for patent infringement). To "grant" such a patent license to a
484 | party means to make such an agreement or commitment not to enforce a
485 | patent against the party.
486 |
487 | If you convey a covered work, knowingly relying on a patent license,
488 | and the Corresponding Source of the work is not available for anyone
489 | to copy, free of charge and under the terms of this License, through a
490 | publicly available network server or other readily accessible means,
491 | then you must either (1) cause the Corresponding Source to be so
492 | available, or (2) arrange to deprive yourself of the benefit of the
493 | patent license for this particular work, or (3) arrange, in a manner
494 | consistent with the requirements of this License, to extend the patent
495 | license to downstream recipients. "Knowingly relying" means you have
496 | actual knowledge that, but for the patent license, your conveying the
497 | covered work in a country, or your recipient's use of the covered work
498 | in a country, would infringe one or more identifiable patents in that
499 | country that you have reason to believe are valid.
500 |
501 | If, pursuant to or in connection with a single transaction or
502 | arrangement, you convey, or propagate by procuring conveyance of, a
503 | covered work, and grant a patent license to some of the parties
504 | receiving the covered work authorizing them to use, propagate, modify
505 | or convey a specific copy of the covered work, then the patent license
506 | you grant is automatically extended to all recipients of the covered
507 | work and works based on it.
508 |
509 | A patent license is "discriminatory" if it does not include within
510 | the scope of its coverage, prohibits the exercise of, or is
511 | conditioned on the non-exercise of one or more of the rights that are
512 | specifically granted under this License. You may not convey a covered
513 | work if you are a party to an arrangement with a third party that is
514 | in the business of distributing software, under which you make payment
515 | to the third party based on the extent of your activity of conveying
516 | the work, and under which the third party grants, to any of the
517 | parties who would receive the covered work from you, a discriminatory
518 | patent license (a) in connection with copies of the covered work
519 | conveyed by you (or copies made from those copies), or (b) primarily
520 | for and in connection with specific products or compilations that
521 | contain the covered work, unless you entered into that arrangement,
522 | or that patent license was granted, prior to 28 March 2007.
523 |
524 | Nothing in this License shall be construed as excluding or limiting
525 | any implied license or other defenses to infringement that may
526 | otherwise be available to you under applicable patent law.
527 |
528 | 12. No Surrender of Others' Freedom.
529 |
530 | If conditions are imposed on you (whether by court order, agreement or
531 | otherwise) that contradict the conditions of this License, they do not
532 | excuse you from the conditions of this License. If you cannot convey a
533 | covered work so as to satisfy simultaneously your obligations under this
534 | License and any other pertinent obligations, then as a consequence you may
535 | not convey it at all. For example, if you agree to terms that obligate you
536 | to collect a royalty for further conveying from those to whom you convey
537 | the Program, the only way you could satisfy both those terms and this
538 | License would be to refrain entirely from conveying the Program.
539 |
540 | 13. Remote Network Interaction; Use with the GNU General Public License.
541 |
542 | Notwithstanding any other provision of this License, if you modify the
543 | Program, your modified version must prominently offer all users
544 | interacting with it remotely through a computer network (if your version
545 | supports such interaction) an opportunity to receive the Corresponding
546 | Source of your version by providing access to the Corresponding Source
547 | from a network server at no charge, through some standard or customary
548 | means of facilitating copying of software. This Corresponding Source
549 | shall include the Corresponding Source for any work covered by version 3
550 | of the GNU General Public License that is incorporated pursuant to the
551 | following paragraph.
552 |
553 | Notwithstanding any other provision of this License, you have
554 | permission to link or combine any covered work with a work licensed
555 | under version 3 of the GNU General Public License into a single
556 | combined work, and to convey the resulting work. The terms of this
557 | License will continue to apply to the part which is the covered work,
558 | but the work with which it is combined will remain governed by version
559 | 3 of the GNU General Public License.
560 |
561 | 14. Revised Versions of this License.
562 |
563 | The Free Software Foundation may publish revised and/or new versions of
564 | the GNU Affero General Public License from time to time. Such new versions
565 | will be similar in spirit to the present version, but may differ in detail to
566 | address new problems or concerns.
567 |
568 | Each version is given a distinguishing version number. If the
569 | Program specifies that a certain numbered version of the GNU Affero General
570 | Public License "or any later version" applies to it, you have the
571 | option of following the terms and conditions either of that numbered
572 | version or of any later version published by the Free Software
573 | Foundation. If the Program does not specify a version number of the
574 | GNU Affero General Public License, you may choose any version ever published
575 | by the Free Software Foundation.
576 |
577 | If the Program specifies that a proxy can decide which future
578 | versions of the GNU Affero General Public License can be used, that proxy's
579 | public statement of acceptance of a version permanently authorizes you
580 | to choose that version for the Program.
581 |
582 | Later license versions may give you additional or different
583 | permissions. However, no additional obligations are imposed on any
584 | author or copyright holder as a result of your choosing to follow a
585 | later version.
586 |
587 | 15. Disclaimer of Warranty.
588 |
589 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
590 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
591 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
592 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
593 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
594 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
595 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
596 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
597 |
598 | 16. Limitation of Liability.
599 |
600 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
601 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
602 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
603 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
604 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
605 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
606 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
607 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
608 | SUCH DAMAGES.
609 |
610 | 17. Interpretation of Sections 15 and 16.
611 |
612 | If the disclaimer of warranty and limitation of liability provided
613 | above cannot be given local legal effect according to their terms,
614 | reviewing courts shall apply local law that most closely approximates
615 | an absolute waiver of all civil liability in connection with the
616 | Program, unless a warranty or assumption of liability accompanies a
617 | copy of the Program in return for a fee.
618 |
619 | END OF TERMS AND CONDITIONS
620 |
621 | How to Apply These Terms to Your New Programs
622 |
623 | If you develop a new program, and you want it to be of the greatest
624 | possible use to the public, the best way to achieve this is to make it
625 | free software which everyone can redistribute and change under these terms.
626 |
627 | To do so, attach the following notices to the program. It is safest
628 | to attach them to the start of each source file to most effectively
629 | state the exclusion of warranty; and each file should have at least
630 | the "copyright" line and a pointer to where the full notice is found.
631 |
632 |
633 | Copyright (C)
634 |
635 | This program is free software: you can redistribute it and/or modify
636 | it under the terms of the GNU Affero General Public License as published
637 | by the Free Software Foundation, either version 3 of the License, or
638 | (at your option) any later version.
639 |
640 | This program is distributed in the hope that it will be useful,
641 | but WITHOUT ANY WARRANTY; without even the implied warranty of
642 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
643 | GNU Affero General Public License for more details.
644 |
645 | You should have received a copy of the GNU Affero General Public License
646 | along with this program. If not, see .
647 |
648 | Also add information on how to contact you by electronic and paper mail.
649 |
650 | If your software can interact with users remotely through a computer
651 | network, you should also make sure that it provides a way for users to
652 | get its source. For example, if your program is a web application, its
653 | interface could display a "Source" link that leads users to an archive
654 | of the code. There are many ways you could offer source, and different
655 | solutions will be better for different programs; see section 13 for the
656 | specific requirements.
657 |
658 | You should also get your employer (if you work as a programmer) or school,
659 | if any, to sign a "copyright disclaimer" for the program, if necessary.
660 | For more information on this, and how to apply and follow the GNU AGPL, see
661 | .

1 | GNU LESSER GENERAL PUBLIC LICENSE
2 | Version 2.1, February 1999
3 |
4 | Copyright (C) 1991, 1999 Free Software Foundation, Inc.
5 | 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
6 | Everyone is permitted to copy and distribute verbatim copies
7 | of this license document, but changing it is not allowed.
8 |
9 | [This is the first released version of the Lesser GPL. It also counts
10 | as the successor of the GNU Library Public License, version 2, hence
11 | the version number 2.1.]
12 |
13 | Preamble
14 |
15 | The licenses for most software are designed to take away your
16 | freedom to share and change it. By contrast, the GNU General Public
17 | Licenses are intended to guarantee your freedom to share and change
18 | free software--to make sure the software is free for all its users.
19 |
20 | This license, the Lesser General Public License, applies to some
21 | specially designated software packages--typically libraries--of the
22 | Free Software Foundation and other authors who decide to use it. You
23 | can use it too, but we suggest you first think carefully about whether
24 | this license or the ordinary General Public License is the better
25 | strategy to use in any particular case, based on the explanations below.
26 |
27 | When we speak of free software, we are referring to freedom of use,
28 | not price. Our General Public Licenses are designed to make sure that
29 | you have the freedom to distribute copies of free software (and charge
30 | for this service if you wish); that you receive source code or can get
31 | it if you want it; that you can change the software and use pieces of
32 | it in new free programs; and that you are informed that you can do
33 | these things.
34 |
35 | To protect your rights, we need to make restrictions that forbid
36 | distributors to deny you these rights or to ask you to surrender these
37 | rights. These restrictions translate to certain responsibilities for
38 | you if you distribute copies of the library or if you modify it.
39 |
40 | For example, if you distribute copies of the library, whether gratis
41 | or for a fee, you must give the recipients all the rights that we gave
42 | you. You must make sure that they, too, receive or can get the source
43 | code. If you link other code with the library, you must provide
44 | complete object files to the recipients, so that they can relink them
45 | with the library after making changes to the library and recompiling
46 | it. And you must show them these terms so they know their rights.
47 |
48 | We protect your rights with a two-step method: (1) we copyright the
49 | library, and (2) we offer you this license, which gives you legal
50 | permission to copy, distribute and/or modify the library.
51 |
52 | To protect each distributor, we want to make it very clear that
53 | there is no warranty for the free library. Also, if the library is
54 | modified by someone else and passed on, the recipients should know
55 | that what they have is not the original version, so that the original
56 | author's reputation will not be affected by problems that might be
57 | introduced by others.
58 |
59 | Finally, software patents pose a constant threat to the existence of
60 | any free program. We wish to make sure that a company cannot
61 | effectively restrict the users of a free program by obtaining a
62 | restrictive license from a patent holder. Therefore, we insist that
63 | any patent license obtained for a version of the library must be
64 | consistent with the full freedom of use specified in this license.
65 |
66 | Most GNU software, including some libraries, is covered by the
67 | ordinary GNU General Public License. This license, the GNU Lesser
68 | General Public License, applies to certain designated libraries, and
69 | is quite different from the ordinary General Public License. We use
70 | this license for certain libraries in order to permit linking those
71 | libraries into non-free programs.
72 |
73 | When a program is linked with a library, whether statically or using
74 | a shared library, the combination of the two is legally speaking a
75 | combined work, a derivative of the original library. The ordinary
76 | General Public License therefore permits such linking only if the
77 | entire combination fits its criteria of freedom. The Lesser General
78 | Public License permits more lax criteria for linking other code with
79 | the library.
80 |
81 | We call this license the "Lesser" General Public License because it
82 | does Less to protect the user's freedom than the ordinary General
83 | Public License. It also provides other free software developers Less
84 | of an advantage over competing non-free programs. These disadvantages
85 | are the reason we use the ordinary General Public License for many
86 | libraries. However, the Lesser license provides advantages in certain
87 | special circumstances.
88 |
89 | For example, on rare occasions, there may be a special need to
90 | encourage the widest possible use of a certain library, so that it becomes
91 | a de-facto standard. To achieve this, non-free programs must be
92 | allowed to use the library. A more frequent case is that a free
93 | library does the same job as widely used non-free libraries. In this
94 | case, there is little to gain by limiting the free library to free
95 | software only, so we use the Lesser General Public License.
96 |
97 | In other cases, permission to use a particular library in non-free
98 | programs enables a greater number of people to use a large body of
99 | free software. For example, permission to use the GNU C Library in
100 | non-free programs enables many more people to use the whole GNU
101 | operating system, as well as its variant, the GNU/Linux operating
102 | system.
103 |
104 | Although the Lesser General Public License is Less protective of the
105 | users' freedom, it does ensure that the user of a program that is
106 | linked with the Library has the freedom and the wherewithal to run
107 | that program using a modified version of the Library.
108 |
109 | The precise terms and conditions for copying, distribution and
110 | modification follow. Pay close attention to the difference between a
111 | "work based on the library" and a "work that uses the library". The
112 | former contains code derived from the library, whereas the latter must
113 | be combined with the library in order to run.
114 |
115 | GNU LESSER GENERAL PUBLIC LICENSE
116 | TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
117 |
118 | 0. This License Agreement applies to any software library or other
119 | program which contains a notice placed by the copyright holder or
120 | other authorized party saying it may be distributed under the terms of
121 | this Lesser General Public License (also called "this License").
122 | Each licensee is addressed as "you".
123 |
124 | A "library" means a collection of software functions and/or data
125 | prepared so as to be conveniently linked with application programs
126 | (which use some of those functions and data) to form executables.
127 |
128 | The "Library", below, refers to any such software library or work
129 | which has been distributed under these terms. A "work based on the
130 | Library" means either the Library or any derivative work under
131 | copyright law: that is to say, a work containing the Library or a
132 | portion of it, either verbatim or with modifications and/or translated
133 | straightforwardly into another language. (Hereinafter, translation is
134 | included without limitation in the term "modification".)
135 |
136 | "Source code" for a work means the preferred form of the work for
137 | making modifications to it. For a library, complete source code means
138 | all the source code for all modules it contains, plus any associated
139 | interface definition files, plus the scripts used to control compilation
140 | and installation of the library.
141 |
142 | Activities other than copying, distribution and modification are not
143 | covered by this License; they are outside its scope. The act of
144 | running a program using the Library is not restricted, and output from
145 | such a program is covered only if its contents constitute a work based
146 | on the Library (independent of the use of the Library in a tool for
147 | writing it). Whether that is true depends on what the Library does
148 | and what the program that uses the Library does.
149 |
150 | 1. You may copy and distribute verbatim copies of the Library's
151 | complete source code as you receive it, in any medium, provided that
152 | you conspicuously and appropriately publish on each copy an
153 | appropriate copyright notice and disclaimer of warranty; keep intact
154 | all the notices that refer to this License and to the absence of any
155 | warranty; and distribute a copy of this License along with the
156 | Library.
157 |
158 | You may charge a fee for the physical act of transferring a copy,
159 | and you may at your option offer warranty protection in exchange for a
160 | fee.
161 |
162 | 2. You may modify your copy or copies of the Library or any portion
163 | of it, thus forming a work based on the Library, and copy and
164 | distribute such modifications or work under the terms of Section 1
165 | above, provided that you also meet all of these conditions:
166 |
167 | a) The modified work must itself be a software library.
168 |
169 | b) You must cause the files modified to carry prominent notices
170 | stating that you changed the files and the date of any change.
171 |
172 | c) You must cause the whole of the work to be licensed at no
173 | charge to all third parties under the terms of this License.
174 |
175 | d) If a facility in the modified Library refers to a function or a
176 | table of data to be supplied by an application program that uses
177 | the facility, other than as an argument passed when the facility
178 | is invoked, then you must make a good faith effort to ensure that,
179 | in the event an application does not supply such function or
180 | table, the facility still operates, and performs whatever part of
181 | its purpose remains meaningful.
182 |
183 | (For example, a function in a library to compute square roots has
184 | a purpose that is entirely well-defined independent of the
185 | application. Therefore, Subsection 2d requires that any
186 | application-supplied function or table used by this function must
187 | be optional: if the application does not supply it, the square
188 | root function must still compute square roots.)
189 |
190 | These requirements apply to the modified work as a whole. If
191 | identifiable sections of that work are not derived from the Library,
192 | and can be reasonably considered independent and separate works in
193 | themselves, then this License, and its terms, do not apply to those
194 | sections when you distribute them as separate works. But when you
195 | distribute the same sections as part of a whole which is a work based
196 | on the Library, the distribution of the whole must be on the terms of
197 | this License, whose permissions for other licensees extend to the
198 | entire whole, and thus to each and every part regardless of who wrote
199 | it.
200 |
201 | Thus, it is not the intent of this section to claim rights or contest
202 | your rights to work written entirely by you; rather, the intent is to
203 | exercise the right to control the distribution of derivative or
204 | collective works based on the Library.
205 |
206 | In addition, mere aggregation of another work not based on the Library
207 | with the Library (or with a work based on the Library) on a volume of
208 | a storage or distribution medium does not bring the other work under
209 | the scope of this License.
210 |
211 | 3. You may opt to apply the terms of the ordinary GNU General Public
212 | License instead of this License to a given copy of the Library. To do
213 | this, you must alter all the notices that refer to this License, so
214 | that they refer to the ordinary GNU General Public License, version 2,
215 | instead of to this License. (If a newer version than version 2 of the
216 | ordinary GNU General Public License has appeared, then you can specify
217 | that version instead if you wish.) Do not make any other change in
218 | these notices.
219 |
220 | Once this change is made in a given copy, it is irreversible for
221 | that copy, so the ordinary GNU General Public License applies to all
222 | subsequent copies and derivative works made from that copy.
223 |
224 | This option is useful when you wish to copy part of the code of
225 | the Library into a program that is not a library.
226 |
227 | 4. You may copy and distribute the Library (or a portion or
228 | derivative of it, under Section 2) in object code or executable form
229 | under the terms of Sections 1 and 2 above provided that you accompany
230 | it with the complete corresponding machine-readable source code, which
231 | must be distributed under the terms of Sections 1 and 2 above on a
232 | medium customarily used for software interchange.
233 |
234 | If distribution of object code is made by offering access to copy
235 | from a designated place, then offering equivalent access to copy the
236 | source code from the same place satisfies the requirement to
237 | distribute the source code, even though third parties are not
238 | compelled to copy the source along with the object code.
239 |
240 | 5. A program that contains no derivative of any portion of the
241 | Library, but is designed to work with the Library by being compiled or
242 | linked with it, is called a "work that uses the Library". Such a
243 | work, in isolation, is not a derivative work of the Library, and
244 | therefore falls outside the scope of this License.
245 |
246 | However, linking a "work that uses the Library" with the Library
247 | creates an executable that is a derivative of the Library (because it
248 | contains portions of the Library), rather than a "work that uses the
249 | library". The executable is therefore covered by this License.
250 | Section 6 states terms for distribution of such executables.
251 |
252 | When a "work that uses the Library" uses material from a header file
253 | that is part of the Library, the object code for the work may be a
254 | derivative work of the Library even though the source code is not.
255 | Whether this is true is especially significant if the work can be
256 | linked without the Library, or if the work is itself a library. The
257 | threshold for this to be true is not precisely defined by law.
258 |
259 | If such an object file uses only numerical parameters, data
260 | structure layouts and accessors, and small macros and small inline
261 | functions (ten lines or less in length), then the use of the object
262 | file is unrestricted, regardless of whether it is legally a derivative
263 | work. (Executables containing this object code plus portions of the
264 | Library will still fall under Section 6.)
265 |
266 | Otherwise, if the work is a derivative of the Library, you may
267 | distribute the object code for the work under the terms of Section 6.
268 | Any executables containing that work also fall under Section 6,
269 | whether or not they are linked directly with the Library itself.
270 |
271 | 6. As an exception to the Sections above, you may also combine or
272 | link a "work that uses the Library" with the Library to produce a
273 | work containing portions of the Library, and distribute that work
274 | under terms of your choice, provided that the terms permit
275 | modification of the work for the customer's own use and reverse
276 | engineering for debugging such modifications.
277 |
278 | You must give prominent notice with each copy of the work that the
279 | Library is used in it and that the Library and its use are covered by
280 | this License. You must supply a copy of this License. If the work
281 | during execution displays copyright notices, you must include the
282 | copyright notice for the Library among them, as well as a reference
283 | directing the user to the copy of this License. Also, you must do one
284 | of these things:
285 |
286 | a) Accompany the work with the complete corresponding
287 | machine-readable source code for the Library including whatever
288 | changes were used in the work (which must be distributed under
289 | Sections 1 and 2 above); and, if the work is an executable linked
290 | with the Library, with the complete machine-readable "work that
291 | uses the Library", as object code and/or source code, so that the
292 | user can modify the Library and then relink to produce a modified
293 | executable containing the modified Library. (It is understood
294 | that the user who changes the contents of definitions files in the
295 | Library will not necessarily be able to recompile the application
296 | to use the modified definitions.)
297 |
298 | b) Use a suitable shared library mechanism for linking with the
299 | Library. A suitable mechanism is one that (1) uses at run time a
300 | copy of the library already present on the user's computer system,
301 | rather than copying library functions into the executable, and (2)
302 | will operate properly with a modified version of the library, if
303 | the user installs one, as long as the modified version is
304 | interface-compatible with the version that the work was made with.
305 |
306 | c) Accompany the work with a written offer, valid for at
307 | least three years, to give the same user the materials
308 | specified in Subsection 6a, above, for a charge no more
309 | than the cost of performing this distribution.
310 |
311 | d) If distribution of the work is made by offering access to copy
312 | from a designated place, offer equivalent access to copy the above
313 | specified materials from the same place.
314 |
315 | e) Verify that the user has already received a copy of these
316 | materials or that you have already sent this user a copy.
317 |
318 | For an executable, the required form of the "work that uses the
319 | Library" must include any data and utility programs needed for
320 | reproducing the executable from it. However, as a special exception,
321 | the materials to be distributed need not include anything that is
322 | normally distributed (in either source or binary form) with the major
323 | components (compiler, kernel, and so on) of the operating system on
324 | which the executable runs, unless that component itself accompanies
325 | the executable.
326 |
327 | It may happen that this requirement contradicts the license
328 | restrictions of other proprietary libraries that do not normally
329 | accompany the operating system. Such a contradiction means you cannot
330 | use both them and the Library together in an executable that you
331 | distribute.
332 |
333 | 7. You may place library facilities that are a work based on the
334 | Library side-by-side in a single library together with other library
335 | facilities not covered by this License, and distribute such a combined
336 | library, provided that the separate distribution of the work based on
337 | the Library and of the other library facilities is otherwise
338 | permitted, and provided that you do these two things:
339 |
340 | a) Accompany the combined library with a copy of the same work
341 | based on the Library, uncombined with any other library
342 | facilities. This must be distributed under the terms of the
343 | Sections above.
344 |
345 | b) Give prominent notice with the combined library of the fact
346 | that part of it is a work based on the Library, and explaining
347 | where to find the accompanying uncombined form of the same work.
348 |
349 | 8. You may not copy, modify, sublicense, link with, or distribute
350 | the Library except as expressly provided under this License. Any
351 | attempt otherwise to copy, modify, sublicense, link with, or
352 | distribute the Library is void, and will automatically terminate your
353 | rights under this License. However, parties who have received copies,
354 | or rights, from you under this License will not have their licenses
355 | terminated so long as such parties remain in full compliance.
356 |
357 | 9. You are not required to accept this License, since you have not
358 | signed it. However, nothing else grants you permission to modify or
359 | distribute the Library or its derivative works. These actions are
360 | prohibited by law if you do not accept this License. Therefore, by
361 | modifying or distributing the Library (or any work based on the
362 | Library), you indicate your acceptance of this License to do so, and
363 | all its terms and conditions for copying, distributing or modifying
364 | the Library or works based on it.
365 |
366 | 10. Each time you redistribute the Library (or any work based on the
367 | Library), the recipient automatically receives a license from the
368 | original licensor to copy, distribute, link with or modify the Library
369 | subject to these terms and conditions. You may not impose any further
370 | restrictions on the recipients' exercise of the rights granted herein.
371 | You are not responsible for enforcing compliance by third parties with
372 | this License.
373 |
374 | 11. If, as a consequence of a court judgment or allegation of patent
375 | infringement or for any other reason (not limited to patent issues),
376 | conditions are imposed on you (whether by court order, agreement or
377 | otherwise) that contradict the conditions of this License, they do not
378 | excuse you from the conditions of this License. If you cannot
379 | distribute so as to satisfy simultaneously your obligations under this
380 | License and any other pertinent obligations, then as a consequence you
381 | may not distribute the Library at all. For example, if a patent
382 | license would not permit royalty-free redistribution of the Library by
383 | all those who receive copies directly or indirectly through you, then
384 | the only way you could satisfy both it and this License would be to
385 | refrain entirely from distribution of the Library.
386 |
387 | If any portion of this section is held invalid or unenforceable under any
388 | particular circumstance, the balance of the section is intended to apply,
389 | and the section as a whole is intended to apply in other circumstances.
390 |
391 | It is not the purpose of this section to induce you to infringe any
392 | patents or other property right claims or to contest validity of any
393 | such claims; this section has the sole purpose of protecting the
394 | integrity of the free software distribution system which is
395 | implemented by public license practices. Many people have made
396 | generous contributions to the wide range of software distributed
397 | through that system in reliance on consistent application of that
398 | system; it is up to the author/donor to decide if he or she is willing
399 | to distribute software through any other system and a licensee cannot
400 | impose that choice.
401 |
402 | This section is intended to make thoroughly clear what is believed to
403 | be a consequence of the rest of this License.
404 |
405 | 12. If the distribution and/or use of the Library is restricted in
406 | certain countries either by patents or by copyrighted interfaces, the
407 | original copyright holder who places the Library under this License may add
408 | an explicit geographical distribution limitation excluding those countries,
409 | so that distribution is permitted only in or among countries not thus
410 | excluded. In such case, this License incorporates the limitation as if
411 | written in the body of this License.
412 |
413 | 13. The Free Software Foundation may publish revised and/or new
414 | versions of the Lesser General Public License from time to time.
415 | Such new versions will be similar in spirit to the present version,
416 | but may differ in detail to address new problems or concerns.
417 |
418 | Each version is given a distinguishing version number. If the Library
419 | specifies a version number of this License which applies to it and
420 | "any later version", you have the option of following the terms and
421 | conditions either of that version or of any later version published by
422 | the Free Software Foundation. If the Library does not specify a
423 | license version number, you may choose any version ever published by
424 | the Free Software Foundation.
425 |
426 | 14. If you wish to incorporate parts of the Library into other free
427 | programs whose distribution conditions are incompatible with these,
428 | write to the author to ask for permission. For software which is
429 | copyrighted by the Free Software Foundation, write to the Free
430 | Software Foundation; we sometimes make exceptions for this. Our
431 | decision will be guided by the two goals of preserving the free status
432 | of all derivatives of our free software and of promoting the sharing
433 | and reuse of software generally.
434 |
435 | NO WARRANTY
436 |
437 | 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
438 | WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
439 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
440 | OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
441 | KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
442 | IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
443 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
444 | LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
445 | THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
446 |
447 | 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
448 | WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
449 | AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
450 | FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
451 | CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
452 | LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
453 | RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
454 | FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
455 | SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
456 | DAMAGES.
457 |
458 | END OF TERMS AND CONDITIONS
459 |
460 | How to Apply These Terms to Your New Libraries
461 |
462 | If you develop a new library, and you want it to be of the greatest
463 | possible use to the public, we recommend making it free software that
464 | everyone can redistribute and change. You can do so by permitting
465 | redistribution under these terms (or, alternatively, under the terms of the
466 | ordinary General Public License).
467 |
468 | To apply these terms, attach the following notices to the library. It is
469 | safest to attach them to the start of each source file to most effectively
470 | convey the exclusion of warranty; and each file should have at least the
471 | "copyright" line and a pointer to where the full notice is found.
472 |
473 |
474 | Copyright (C)
475 |
476 | This library is free software; you can redistribute it and/or
477 | modify it under the terms of the GNU Lesser General Public
478 | License as published by the Free Software Foundation; either
479 | version 2.1 of the License, or (at your option) any later version.
480 |
481 | This library is distributed in the hope that it will be useful,
482 | but WITHOUT ANY WARRANTY; without even the implied warranty of
483 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
484 | Lesser General Public License for more details.
485 |
486 | You should have received a copy of the GNU Lesser General Public
487 | License along with this library; if not, write to the Free Software
488 | Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
489 |
490 | Also add information on how to contact you by electronic and paper mail.
491 |
492 | You should also get your employer (if you work as a programmer) or your
493 | school, if any, to sign a "copyright disclaimer" for the library, if
494 | necessary. Here is a sample; alter the names:
495 |
496 | Yoyodyne, Inc., hereby disclaims all copyright interest in the
497 | library `Frob' (a library for tweaking knobs) written by James Random Hacker.
498 |

23 | 1 - Introduction
24 | ================
25 |
26 | PclZip is a library that allow you to manage a Zip archive.
27 |
28 | Full documentation about PclZip can be found here : http://www.phpconcept.net/pclzip
29 |
30 | 2 - What's new
31 | ==============
32 |
33 | Version 2.8.4 :
34 | - Update composer.json to indicate that pclzip/pclzip is replaced
35 |
36 | Version 2.8.3 :
37 | - Fix compatibility with PHP v7.1
38 |
39 | Version 2.8.2 :
40 | - PCLZIP_CB_PRE_EXTRACT and PCLZIP_CB_POST_EXTRACT are now supported with
41 | extraction as a string (PCLZIP_OPT_EXTRACT_AS_STRING). The string
42 | can also be modified in the post-extract call back.
43 | **Bugs correction :
44 | - PCLZIP_OPT_REMOVE_ALL_PATH was not working correctly
45 | - Remove use of eval() and do direct call to callback functions
46 | - Correct support of 64bits systems (Thanks to WordPress team)
47 |
48 | Version 2.8.1 :
49 | - Move option PCLZIP_OPT_BY_EREG to PCLZIP_OPT_BY_PREG because ereg() is
50 | deprecated in PHP 5.3. When using option PCLZIP_OPT_BY_EREG, PclZip will
51 | automatically replace it by PCLZIP_OPT_BY_PREG.
52 |
53 | Version 2.8 :
54 | - Improve extraction of zip archive for large files by using temporary files
55 | This feature is working like the one defined in r2.7.
56 | Options are renamed : PCLZIP_OPT_TEMP_FILE_ON, PCLZIP_OPT_TEMP_FILE_OFF,
57 | PCLZIP_OPT_TEMP_FILE_THRESHOLD
58 | - Add a ratio constant PCLZIP_TEMPORARY_FILE_RATIO to configure the auto
59 | sense of temporary file use.
60 | - Bug correction : Reduce filepath in returned file list to remove ennoying
61 | './/' preambule in file path.
62 |
63 | Version 2.7 :
64 | - Improve creation of zip archive for large files :
65 | PclZip will now autosense the configured memory and use temporary files
66 | when large file is suspected.
67 | This feature can also ne triggered by manual options in create() and add()
68 | methods. 'PCLZIP_OPT_ADD_TEMP_FILE_ON' force the use of temporary files,
69 | 'PCLZIP_OPT_ADD_TEMP_FILE_OFF' disable the autosense technic,
70 | 'PCLZIP_OPT_ADD_TEMP_FILE_THRESHOLD' allow for configuration of a size
71 | threshold to use temporary files.
72 | Using "temporary files" rather than "memory" might take more time, but
73 | might give the ability to zip very large files :
74 | Tested on my win laptop with a 88Mo file :
75 | Zip "in-memory" : 18sec (max_execution_time=30, memory_limit=180Mo)
76 | Zip "tmporary-files" : 23sec (max_execution_time=30, memory_limit=30Mo)
77 | - Replace use of mktime() by time() to limit the E_STRICT error messages.
78 | - Bug correction : When adding files with full windows path (drive letter)
79 | PclZip is now working. Before, if the drive letter is not the default
80 | path, PclZip was not able to add the file.
81 |
82 | Version 2.6 :
83 | - Code optimisation
84 | - New attributes PCLZIP_ATT_FILE_COMMENT gives the ability to
85 | add a comment for a specific file. (Don't really know if this is usefull)
86 | - New attribute PCLZIP_ATT_FILE_CONTENT gives the ability to add a string
87 | as a file.
88 | - New attribute PCLZIP_ATT_FILE_MTIME modify the timestamp associated with
89 | a file.
90 | - Correct a bug. Files archived with a timestamp with 0h0m0s were extracted
91 | with current time
92 | - Add CRC value in the informations returned back for each file after an
93 | action.
94 | - Add missing closedir() statement.
95 | - When adding a folder, and removing the path of this folder, files were
96 | incorrectly added with a '/' at the beginning. Which means files are
97 | related to root in unix systems. Corrected.
98 | - Add conditional if before constant definition. This will allow users
99 | to redefine constants without changing the file, and then improve
100 | upgrade of pclzip code for new versions.
101 |
102 | Version 2.5 :
103 | - Introduce the ability to add file/folder with individual properties (file descriptor).
104 | This gives for example the ability to change the filename of a zipped file.
105 | . Able to add files individually
106 | . Able to change full name
107 | . Able to change short name
108 | . Compatible with global options
109 | - New attributes : PCLZIP_ATT_FILE_NAME, PCLZIP_ATT_FILE_NEW_SHORT_NAME, PCLZIP_ATT_FILE_NEW_FULL_NAME
110 | - New error code : PCLZIP_ERR_INVALID_ATTRIBUTE_VALUE
111 | - Add a security control feature. PclZip can extract any file in any folder
112 | of a system. People may use this to upload a zip file and try to override
113 | a system file. The PCLZIP_OPT_EXTRACT_DIR_RESTRICTION will give the
114 | ability to forgive any directory transversal behavior.
115 | - New PCLZIP_OPT_EXTRACT_DIR_RESTRICTION : check extraction path
116 | - New error code : PCLZIP_ERR_DIRECTORY_RESTRICTION
117 | - Modification in PclZipUtilPathInclusion() : dir and path beginning with ./ will be prepend
118 | by current path (getcwd())
119 |
120 | Version 2.4 :
121 | - Code improvment : try to speed up the code by removing unusefull call to pack()
122 | - Correct bug in delete() : delete() should be called with no argument. This was not
123 | the case in 2.3. This is corrected in 2.4.
124 | - Correct a bug in path_inclusion function. When the path has several '../../', the
125 | result was bad.
126 | - Add a check for magic_quotes_runtime configuration. If enabled, PclZip will
127 | disable it while working and det it back to its original value.
128 | This resolve a lots of bad formated archive errors.
129 | - Bug correction : PclZip now correctly unzip file in some specific situation,
130 | when compressed content has same size as uncompressed content.
131 | - Bug correction : When selecting option 'PCLZIP_OPT_REMOVE_ALL_PATH',
132 | directories are not any more created.
133 | - Code improvment : correct unclosed opendir(), better handling of . and .. in
134 | loops.
135 |
136 |
137 | Version 2.3 :
138 | - Correct a bug with PHP5 : affecting the value 0xFE49FFE0 to a variable does not
139 | give the same result in PHP4 and PHP5 ....
140 |
141 | Version 2.2 :
142 | - Try development of PCLZIP_OPT_CRYPT .....
143 | However this becomes to a stop. To crypt/decrypt I need to multiply 2 long integers,
144 | the result (greater than a long) is not supported by PHP. Even the use of bcmath
145 | functions does not help. I did not find yet a solution ...;
146 | - Add missing '/' at end of directory entries
147 | - Check is a file is encrypted or not. Returns status 'unsupported_encryption' and/or
148 | error code PCLZIP_ERR_UNSUPPORTED_ENCRYPTION.
149 | - Corrected : Bad "version need to extract" field in local file header
150 | - Add private method privCheckFileHeaders() in order to check local and central
151 | file headers. PclZip is now supporting purpose bit flag bit 3. Purpose bit flag bit 3 gives
152 | the ability to have a local file header without size, compressed size and crc filled.
153 | - Add a generic status 'error' for file status
154 | - Add control of compression type. PclZip only support deflate compression method.
155 | Before v2.2, PclZip does not check the compression method used in an archive while
156 | extracting. With v2.2 PclZip returns a new error status for a file using an unsupported
157 | compression method. New status is "unsupported_compression". New error code is
158 | PCLZIP_ERR_UNSUPPORTED_COMPRESSION.
159 | - Add optional attribute PCLZIP_OPT_STOP_ON_ERROR. This will stop the extract of files
160 | when errors like 'a folder with same name exists' or 'a newer file exists' or
161 | 'a write protected file' exists, rather than set a status for the concerning file
162 | and resume the extract of the zip.
163 | - Add optional attribute PCLZIP_OPT_REPLACE_NEWER. This will force, during an extract' the
164 | replacement of the file, even if a newer version of the file exists.
165 | Note that today if a file with the same name already exists but is older it will be
166 | replaced by the extracted one.
167 | - Improve PclZipUtilOption()
168 | - Support of zip archive with trailing bytes. Before 2.2, PclZip checks that the central
169 | directory structure is the last data in the archive. Crypt encryption/decryption of
170 | zip archive put trailing 0 bytes after decryption. PclZip is now supporting this.
171 |
172 | Version 2.1 :
173 | - Add the ability to abort the extraction by using a user callback function.
174 | The user can now return the value '2' in its callback which indicates to stop the
175 | extraction. For a pre call-back extract is stopped before the extration of the current
176 | file. For a post call back, the extraction is stopped after.
177 | - Add the ability to extract a file (or several files) directly in the standard output.
178 | This is done by the new parameter PCLZIP_OPT_EXTRACT_IN_OUTPUT with method extract().
179 | - Add support for parameters PCLZIP_OPT_COMMENT, PCLZIP_OPT_ADD_COMMENT,
180 | PCLZIP_OPT_PREPEND_COMMENT. This will create, replace, add, or prepend comments
181 | in the zip archive.
182 | - When merging two archives, the comments are not any more lost, but merged, with a
183 | blank space separator.
184 | - Corrected bug : Files are not deleted when all files are asked to be deleted.
185 | - Corrected bug : Folders with name '0' made PclZip to abort the create or add feature.
186 |
187 |
188 | Version 2.0 :
189 | ***** Warning : Some new features may break the backward compatibility for your scripts.
190 | Please carefully read the readme file.
191 | - Add the ability to delete by Index, name and regular expression. This feature is
192 | performed by the method delete(), which uses the optional parameters
193 | PCLZIP_OPT_BY_INDEX, PCLZIP_OPT_BY_NAME, PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG.
194 | - Add the ability to extract by regular expression. To extract by regexp you must use the method
195 | extract(), with the option PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG
196 | (depending if you want to use ereg() or preg_match() syntax) followed by the
197 | regular expression pattern.
198 | - Add the ability to extract by index, directly with the extract() method. This is a
199 | code improvment of the extractByIndex() method.
200 | - Add the ability to extract by name. To extract by name you must use the method
201 | extract(), with the option PCLZIP_OPT_BY_NAME followed by the filename to
202 | extract or an array of filenames to extract. To extract all a folder, use the folder
203 | name rather than the filename with a '/' at the end.
204 | - Add the ability to add files without compression. This is done with a new attribute
205 | which is PCLZIP_OPT_NO_COMPRESSION.
206 | - Add the attribute PCLZIP_OPT_EXTRACT_AS_STRING, which allow to extract a file directly
207 | in a string without using any file (or temporary file).
208 | - Add constant PCLZIP_SEPARATOR for static configuration of filename separators in a single string.
209 | The default separator is now a comma (,) and not any more a blank space.
210 | THIS BREAK THE BACKWARD COMPATIBILITY : Please check if this may have an impact with
211 | your script.
212 | - Improve algorythm performance by removing the use of temporary files when adding or
213 | extracting files in an archive.
214 | - Add (correct) detection of empty filename zipping. This can occurs when the removed
215 | path is the same
216 | as a zipped dir. The dir is not zipped (['status'] = filtered), only its content.
217 | - Add better support for windows paths (thanks for help from manus@manusfreedom.com).
218 | - Corrected bug : When the archive file already exists with size=0, the add() method
219 | fails. Corrected in 2.0.
220 | - Remove the use of OS_WINDOWS constant. Use php_uname() function rather.
221 | - Control the order of index ranges in extract by index feature.
222 | - Change the internal management of folders (better handling of internal flag).
223 |
224 |
225 | Version 1.3 :
226 | - Removing the double include check. This is now done by include_once() and require_once()
227 | PHP directives.
228 | - Changing the error handling mecanism : Remove the use of an external error library.
229 | The former PclError...() functions are replaced by internal equivalent methods.
230 | By changing the environment variable PCLZIP_ERROR_EXTERNAL you can still use the former library.
231 | Introducing the use of constants for error codes rather than integer values. This will help
232 | in futur improvment.
233 | Introduction of error handling functions like errorCode(), errorName() and errorInfo().
234 | - Remove the deprecated use of calling function with arguments passed by reference.
235 | - Add the calling of extract(), extractByIndex(), create() and add() functions
236 | with variable options rather than fixed arguments.
237 | - Add the ability to remove all the file path while extracting or adding,
238 | without any need to specify the path to remove.
239 | This is available for extract(), extractByIndex(), create() and add() functionS by using
240 | the new variable options parameters :
241 | - PCLZIP_OPT_REMOVE_ALL_PATH : by indicating this option while calling the fct.
242 | - Ability to change the mode of a file after the extraction (chmod()).
243 | This is available for extract() and extractByIndex() functionS by using
244 | the new variable options parameters.
245 | - PCLZIP_OPT_SET_CHMOD : by setting the value of this option.
246 | - Ability to definition call-back options. These call-back will be called during the adding,
247 | or the extracting of file (extract(), extractByIndex(), create() and add() functions) :
248 | - PCLZIP_CB_PRE_EXTRACT : will be called before each extraction of a file. The user
249 | can trigerred the change the filename of the extracted file. The user can triggered the
250 | skip of the extraction. This is adding a 'skipped' status in the file list result value.
251 | - PCLZIP_CB_POST_EXTRACT : will be called after each extraction of a file.
252 | Nothing can be triggered from that point.
253 | - PCLZIP_CB_PRE_ADD : will be called before each add of a file. The user
254 | can trigerred the change the stored filename of the added file. The user can triggered the
255 | skip of the add. This is adding a 'skipped' status in the file list result value.
256 | - PCLZIP_CB_POST_ADD : will be called after each add of a file.
257 | Nothing can be triggered from that point.
258 | - Two status are added in the file list returned as function result : skipped & filename_too_long
259 | 'skipped' is used when a call-back function ask for skipping the file.
260 | 'filename_too_long' is used while adding a file with a too long filename to archive (the file is
261 | not added)
262 | - Adding the function PclZipUtilPathInclusion(), that check the inclusion of a path into
263 | a directory.
264 | - Add a check of the presence of the archive file before some actions (like list, ...)
265 | - Add the initialisation of field "index" in header array. This means that by
266 | default index will be -1 when not explicitly set by the methods.
267 |
268 | Version 1.2 :
269 | - Adding a duplicate function.
270 | - Adding a merge function. The merge function is a "quick merge" function,
271 | it just append the content of an archive at the end of the first one. There
272 | is no check for duplicate files or more recent files.
273 | - Improve the search of the central directory end.
274 |
275 | Version 1.1.2 :
276 |
277 | - Changing the license of PclZip. PclZip is now released under the GNU / LGPL license
278 | (see License section).
279 | - Adding the optional support of a static temporary directory. You will need to configure
280 | the constant PCLZIP_TEMPORARY_DIR if you want to use this feature.
281 | - Improving the rename() function. In some cases rename() does not work (different
282 | Filesystems), so it will be replaced by a copy() + unlink() functions.
283 |
284 | Version 1.1.1 :
285 |
286 | - Maintenance release, no new feature.
287 |
288 | Version 1.1 :
289 |
290 | - New method Add() : adding files in the archive
291 | - New method ExtractByIndex() : partial extract of the archive, files are identified by
292 | their index in the archive
293 | - New method DeleteByIndex() : delete some files/folder entries from the archive,
294 | files are identified by their index in the archive.
295 | - Adding a test of the zlib extension presence. If not present abort the script.
296 |
297 | Version 1.0.1 :
298 |
299 | - No new feature
300 |
301 |
302 | 3 - Corrected bugs
303 | ==================
304 |
305 | Corrected in Version 2.0 :
306 | - Corrected : During an extraction, if a call-back fucntion is used and try to skip
307 | a file, all the extraction process is stopped.
308 |
309 | Corrected in Version 1.3 :
310 | - Corrected : Support of static synopsis for method extract() is broken.
311 | - Corrected : invalid size of archive content field (0xFF) should be (0xFFFF).
312 | - Corrected : When an extract is done with a remove_path parameter, the entry for
313 | the directory with exactly the same path is not skipped/filtered.
314 | - Corrected : extractByIndex() and deleteByIndex() were not managing index in the
315 | right way. For example indexes '1,3-5,11' will only extract files 1 and 11. This
316 | is due to a sort of the index resulting table that puts 11 before 3-5 (sort on
317 | string and not interger). The sort is temporarilly removed, this means that
318 | you must provide a sorted list of index ranges.
319 |
320 | Corrected in Version 1.2 :
321 |
322 | - Nothing.
323 |
324 | Corrected in Version 1.1.2 :
325 |
326 | - Corrected : Winzip is unable to delete or add new files in a PclZip created archives.
327 |
328 | Corrected in Version 1.1.1 :
329 |
330 | - Corrected : When archived file is not compressed (0% compression), the
331 | extract method fails.
332 |
333 | Corrected in Version 1.1 :
334 |
335 | - Corrected : Adding a complete tree of folder may result in a bad archive
336 | creation.
337 |
338 | Corrected in Version 1.0.1 :
339 |
340 | - Corrected : Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024).
341 |

343 | 4 - Known bugs or limitations
344 | =============================
345 |
346 | Please publish bugs reports in SourceForge :
347 | http://sourceforge.net/tracker/?group_id=40254&atid=427564
348 |
349 | In Version 2.x :
350 | - PclZip does only support file uncompressed or compressed with deflate (compression method 8)
351 | - PclZip does not support password protected zip archive
352 | - Some concern were seen when changing mtime of a file while archiving.
353 | Seems to be linked to Daylight Saving Time (PclTest_changing_mtime).
354 |
355 | In Version 1.2 :
356 |
357 | - merge() methods does not check for duplicate files or last date of modifications.
358 |
359 | In Version 1.1 :
360 |
361 | - Limitation : Using 'extract' fields in the file header in the zip archive is not supported.
362 | - WinZip is unable to delete a single file in a PclZip created archive. It is also unable to
363 | add a file in a PclZip created archive. (Corrected in v.1.2)
364 |
365 | In Version 1.0.1 :
366 |
367 | - Adding a complete tree of folder may result in a bad archive
368 | creation. (Corrected in V.1.1).
369 | - Path given to methods must be in the unix format (/) and not the Windows format (\).
370 | Workaround : Use only / directory separators.
371 | - PclZip is using temporary files that are sometime the name of the file with a .tmp or .gz
372 | added suffix. Files with these names may already exist and may be overwritten.
373 | Workaround : none.
374 | - PclZip does not check if the zlib extension is present. If it is absent, the zip
375 | file is not created and the lib abort without warning.
376 | Workaround : enable the zlib extension on the php install
377 |
378 | In Version 1.0 :
379 |
380 | - Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024).
381 | (Corrected in v.1.0.1)
382 | - Limitation : Multi-disk zip archive are not supported.
