annotate COPYING @ 355:d1f930be4711
From Jeffrey Morlan:
pst_build_id_ptr and pst_build_desc_ptr require that the first child
of a BTree page have the same starting ID as itself. This is not
required by the spec, and is not true in many real-world PSTs
(presumably, the original first child of the page got
deleted). Because of this, many emails are not being extracted from
these PSTs. It also triggers an infinite loop in lspst (a separate
bug, also fixed)

9 Preamble |
| 0 | 10 |
| 11 The licenses for most software are designed to take away your | |
| 12 freedom to share and change it. By contrast, the GNU General Public | |
| 13 License is intended to guarantee your freedom to share and change free | |
| 14 software--to make sure the software is free for all its users. This | |
| 15 General Public License applies to most of the Free Software | |
| 16 Foundation's software and to any other program whose authors commit to | |
| 17 using it. (Some other Free Software Foundation software is covered by | |

18 the GNU Lesser General Public License instead.) You can apply it to |
| 0 | 19 your programs, too. |
| 20 | |
| 21 When we speak of free software, we are referring to freedom, not | |
| 22 price. Our General Public Licenses are designed to make sure that you | |
| 23 have the freedom to distribute copies of free software (and charge for | |
| 24 this service if you wish), that you receive source code or can get it | |
| 25 if you want it, that you can change the software or use pieces of it | |
| 26 in new free programs; and that you know you can do these things. | |
| 27 | |
| 28 To protect your rights, we need to make restrictions that forbid | |
| 29 anyone to deny you these rights or to ask you to surrender the rights. | |
| 30 These restrictions translate to certain responsibilities for you if you | |
| 31 distribute copies of the software, or if you modify it. | |
| 32 | |
| 33 For example, if you distribute copies of such a program, whether | |
| 34 gratis or for a fee, you must give the recipients all the rights that | |
| 35 you have. You must make sure that they, too, receive or can get the | |
| 36 source code. And you must show them these terms so they know their | |
| 37 rights. | |
| 38 | |
| 39 We protect your rights with two steps: (1) copyright the software, and | |
| 40 (2) offer you this license which gives you legal permission to copy, | |
| 41 distribute and/or modify the software. | |
| 42 | |
| 43 Also, for each author's protection and ours, we want to make certain | |
| 44 that everyone understands that there is no warranty for this free | |
| 45 software. If the software is modified by someone else and passed on, we | |
| 46 want its recipients to know that what they have is not the original, so | |
| 47 that any problems introduced by others will not reflect on the original | |
| 48 authors' reputations. | |
| 49 | |
| 50 Finally, any free program is threatened constantly by software | |
| 51 patents. We wish to avoid the danger that redistributors of a free | |
| 52 program will individually obtain patent licenses, in effect making the | |
| 53 program proprietary. To prevent this, we have made it clear that any | |
| 54 patent must be licensed for everyone's free use or not licensed at all. | |
| 55 | |
| 56 The precise terms and conditions for copying, distribution and | |
| 57 modification follow. | |

59 GNU GENERAL PUBLIC LICENSE |
| 0 | 60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| 61 | |
| 62 0. This License applies to any program or other work which contains | |
| 63 a notice placed by the copyright holder saying it may be distributed | |
| 64 under the terms of this General Public License. The "Program", below, | |
| 65 refers to any such program or work, and a "work based on the Program" | |
| 66 means either the Program or any derivative work under copyright law: | |
| 67 that is to say, a work containing the Program or a portion of it, | |
| 68 either verbatim or with modifications and/or translated into another | |
| 69 language. (Hereinafter, translation is included without limitation in | |
| 70 the term "modification".) Each licensee is addressed as "you". | |
| 71 | |
| 72 Activities other than copying, distribution and modification are not | |
| 73 covered by this License; they are outside its scope. The act of | |
| 74 running the Program is not restricted, and the output from the Program | |
| 75 is covered only if its contents constitute a work based on the | |
| 76 Program (independent of having been made by running the Program). | |
| 77 Whether that is true depends on what the Program does. | |
| 78 | |
| 79 1. You may copy and distribute verbatim copies of the Program's | |
| 80 source code as you receive it, in any medium, provided that you | |
| 81 conspicuously and appropriately publish on each copy an appropriate | |
| 82 copyright notice and disclaimer of warranty; keep intact all the | |
| 83 notices that refer to this License and to the absence of any warranty; | |
| 84 and give any other recipients of the Program a copy of this License | |
| 85 along with the Program. | |
| 86 | |
| 87 You may charge a fee for the physical act of transferring a copy, and | |
| 88 you may at your option offer warranty protection in exchange for a fee. | |
| 89 | |
| 90 2. You may modify your copy or copies of the Program or any portion | |
| 91 of it, thus forming a work based on the Program, and copy and | |
| 92 distribute such modifications or work under the terms of Section 1 | |
| 93 above, provided that you also meet all of these conditions: | |
| 94 | |
| 95 a) You must cause the modified files to carry prominent notices | |
| 96 stating that you changed the files and the date of any change. | |
| 97 | |
| 98 b) You must cause any work that you distribute or publish, that in | |
| 99 whole or in part contains or is derived from the Program or any | |
| 100 part thereof, to be licensed as a whole at no charge to all third | |
| 101 parties under the terms of this License. | |
| 102 | |
| 103 c) If the modified program normally reads commands interactively | |
| 104 when run, you must cause it, when started running for such | |
| 105 interactive use in the most ordinary way, to print or display an | |
| 106 announcement including an appropriate copyright notice and a | |
| 107 notice that there is no warranty (or else, saying that you provide | |
| 108 a warranty) and that users may redistribute the program under | |
| 109 these conditions, and telling the user how to view a copy of this | |
| 110 License. (Exception: if the Program itself is interactive but | |
| 111 does not normally print such an announcement, your work based on | |
| 112 the Program is not required to print an announcement.) | |

113 |
| 0 | 114 These requirements apply to the modified work as a whole. If |
| 115 identifiable sections of that work are not derived from the Program, | |
| 116 and can be reasonably considered independent and separate works in | |
| 117 themselves, then this License, and its terms, do not apply to those | |
| 118 sections when you distribute them as separate works. But when you | |
| 119 distribute the same sections as part of a whole which is a work based | |
| 120 on the Program, the distribution of the whole must be on the terms of | |
| 121 this License, whose permissions for other licensees extend to the | |
| 122 entire whole, and thus to each and every part regardless of who wrote it. | |
| 123 | |
| 124 Thus, it is not the intent of this section to claim rights or contest | |
| 125 your rights to work written entirely by you; rather, the intent is to | |
| 126 exercise the right to control the distribution of derivative or | |
| 127 collective works based on the Program. | |
| 128 | |
| 129 In addition, mere aggregation of another work not based on the Program | |
| 130 with the Program (or with a work based on the Program) on a volume of | |
| 131 a storage or distribution medium does not bring the other work under | |
| 132 the scope of this License. | |
| 133 | |
| 134 3. You may copy and distribute the Program (or a work based on it, | |
| 135 under Section 2) in object code or executable form under the terms of | |
| 136 Sections 1 and 2 above provided that you also do one of the following: | |
| 137 | |
| 138 a) Accompany it with the complete corresponding machine-readable | |
| 139 source code, which must be distributed under the terms of Sections | |
| 140 1 and 2 above on a medium customarily used for software interchange; or, | |
| 141 | |
| 142 b) Accompany it with a written offer, valid for at least three | |
| 143 years, to give any third party, for a charge no more than your | |
| 144 cost of physically performing source distribution, a complete | |
| 145 machine-readable copy of the corresponding source code, to be | |
| 146 distributed under the terms of Sections 1 and 2 above on a medium | |
| 147 customarily used for software interchange; or, | |
| 148 | |
| 149 c) Accompany it with the information you received as to the offer | |
| 150 to distribute corresponding source code. (This alternative is | |
| 151 allowed only for noncommercial distribution and only if you | |
| 152 received the program in object code or executable form with such | |
| 153 an offer, in accord with Subsection b above.) | |
| 154 | |
| 155 The source code for a work means the preferred form of the work for | |
| 156 making modifications to it. For an executable work, complete source | |
| 157 code means all the source code for all modules it contains, plus any | |
| 158 associated interface definition files, plus the scripts used to | |
| 159 control compilation and installation of the executable. However, as a | |
| 160 special exception, the source code distributed need not include | |
| 161 anything that is normally distributed (in either source or binary | |
| 162 form) with the major components (compiler, kernel, and so on) of the | |
| 163 operating system on which the executable runs, unless that component | |
| 164 itself accompanies the executable. | |
| 165 | |
| 166 If distribution of executable or object code is made by offering | |
| 167 access to copy from a designated place, then offering equivalent | |
| 168 access to copy the source code from the same place counts as | |
| 169 distribution of the source code, even though third parties are not | |
| 170 compelled to copy the source along with the object code. | |

| 0 | 172 4. You may not copy, modify, sublicense, or distribute the Program |
| 173 except as expressly provided under this License. Any attempt | |
| 174 otherwise to copy, modify, sublicense or distribute the Program is | |
| 175 void, and will automatically terminate your rights under this License. | |
| 176 However, parties who have received copies, or rights, from you under | |
| 177 this License will not have their licenses terminated so long as such | |
| 178 parties remain in full compliance. | |
| 179 | |
| 180 5. You are not required to accept this License, since you have not | |
| 181 signed it. However, nothing else grants you permission to modify or | |
| 182 distribute the Program or its derivative works. These actions are | |
| 183 prohibited by law if you do not accept this License. Therefore, by | |
| 184 modifying or distributing the Program (or any work based on the | |
| 185 Program), you indicate your acceptance of this License to do so, and | |
| 186 all its terms and conditions for copying, distributing or modifying | |
| 187 the Program or works based on it. | |
| 188 | |
| 189 6. Each time you redistribute the Program (or any work based on the | |
| 190 Program), the recipient automatically receives a license from the | |
| 191 original licensor to copy, distribute or modify the Program subject to | |
| 192 these terms and conditions. You may not impose any further | |
| 193 restrictions on the recipients' exercise of the rights granted herein. | |
| 194 You are not responsible for enforcing compliance by third parties to | |
| 195 this License. | |
| 196 | |
| 197 7. If, as a consequence of a court judgment or allegation of patent | |
| 198 infringement or for any other reason (not limited to patent issues), | |
| 199 conditions are imposed on you (whether by court order, agreement or | |
| 200 otherwise) that contradict the conditions of this License, they do not | |
| 201 excuse you from the conditions of this License. If you cannot | |
| 202 distribute so as to satisfy simultaneously your obligations under this | |
| 203 License and any other pertinent obligations, then as a consequence you | |
| 204 may not distribute the Program at all. For example, if a patent | |
| 205 license would not permit royalty-free redistribution of the Program by | |
| 206 all those who receive copies directly or indirectly through you, then | |
| 207 the only way you could satisfy both it and this License would be to | |
| 208 refrain entirely from distribution of the Program. | |
| 209 | |
| 210 If any portion of this section is held invalid or unenforceable under | |
| 211 any particular circumstance, the balance of the section is intended to | |
| 212 apply and the section as a whole is intended to apply in other | |
| 213 circumstances. | |
| 214 | |
| 215 It is not the purpose of this section to induce you to infringe any | |
| 216 patents or other property right claims or to contest validity of any | |
| 217 such claims; this section has the sole purpose of protecting the | |
| 218 integrity of the free software distribution system, which is | |
| 219 implemented by public license practices. Many people have made | |
| 220 generous contributions to the wide range of software distributed | |
| 221 through that system in reliance on consistent application of that | |
| 222 system; it is up to the author/donor to decide if he or she is willing | |
| 223 to distribute software through any other system and a licensee cannot | |
| 224 impose that choice. | |
| 225 | |
| 226 This section is intended to make thoroughly clear what is believed to | |
| 227 be a consequence of the rest of this License. | |

| 0 | 229 8. If the distribution and/or use of the Program is restricted in |
| 230 certain countries either by patents or by copyrighted interfaces, the | |
| 231 original copyright holder who places the Program under this License | |
| 232 may add an explicit geographical distribution limitation excluding | |
| 233 those countries, so that distribution is permitted only in or among | |
| 234 countries not thus excluded. In such case, this License incorporates | |
| 235 the limitation as if written in the body of this License. | |
| 236 | |
| 237 9. The Free Software Foundation may publish revised and/or new versions | |
| 238 of the General Public License from time to time. Such new versions will | |
| 239 be similar in spirit to the present version, but may differ in detail to | |
| 240 address new problems or concerns. | |
| 241 | |
| 242 Each version is given a distinguishing version number. If the Program | |
| 243 specifies a version number of this License which applies to it and "any | |
| 244 later version", you have the option of following the terms and conditions | |
| 245 either of that version or of any later version published by the Free | |
| 246 Software Foundation. If the Program does not specify a version number of | |
| 247 this License, you may choose any version ever published by the Free Software | |
| 248 Foundation. | |
| 249 | |
| 250 10. If you wish to incorporate parts of the Program into other free | |
| 251 programs whose distribution conditions are different, write to the author | |
| 252 to ask for permission. For software which is copyrighted by the Free | |
| 253 Software Foundation, write to the Free Software Foundation; we sometimes | |
| 254 make exceptions for this. Our decision will be guided by the two goals | |
| 255 of preserving the free status of all derivatives of our free software and | |
| 256 of promoting the sharing and reuse of software generally. | |

258 NO WARRANTY |
| 0 | 259 |
| 260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | |
| 261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | |
| 262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
| 263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
| 264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
| 265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |
| 266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
| 267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | |
| 268 REPAIR OR CORRECTION. | |
| 269 | |
| 270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
| 271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
| 272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
| 273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | |
| 274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | |
| 275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | |
| 276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | |
| 277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
| 278 POSSIBILITY OF SUCH DAMAGES. | |
