This package contains a modified version of ca-bundle.crt:
|
| 2 |
+
|
| 3 |
+
ca-bundle.crt -- Bundle of CA Root Certificates
|
| 4 |
+
|
| 5 |
+
This is a bundle of X.509 certificates of public Certificate Authorities
|
| 6 |
+
(CA). These were automatically extracted from Mozilla's root certificates
|
| 7 |
+
file (certdata.txt). This file can be found in the mozilla source tree:
|
| 8 |
+
https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
|
| 9 |
+
It contains the certificates in PEM format and therefore
|
| 10 |
+
can be directly used with curl / libcurl / php_curl, or with
|
| 11 |
+
an Apache+mod_ssl webserver for SSL client authentication.
|
| 12 |
+
Just configure this file as the SSLCACertificateFile.#

A. HISTORY OF THE SOFTWARE
|
| 2 |
+
==========================
|
| 3 |
+
|
| 4 |
+
Python was created in the early 1990s by Guido van Rossum at Stichting
|
| 5 |
+
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
|
| 6 |
+
as a successor of a language called ABC. Guido remains Python's
|
| 7 |
+
principal author, although it includes many contributions from others.
|
| 8 |
+
|
| 9 |
+
In 1995, Guido continued his work on Python at the Corporation for
|
| 10 |
+
National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
|
| 11 |
+
in Reston, Virginia where he released several versions of the
|
| 12 |
+
software.
|
| 13 |
+
|
| 14 |
+
In May 2000, Guido and the Python core development team moved to
|
| 15 |
+
BeOpen.com to form the BeOpen PythonLabs team. In October of the same
|
| 16 |
+
year, the PythonLabs team moved to Digital Creations (now Zope
|
| 17 |
+
Corporation, see http://www.zope.com). In 2001, the Python Software
|
| 18 |
+
Foundation (PSF, see http://www.python.org/psf/) was formed, a
|
| 19 |
+
non-profit organization created specifically to own Python-related
|
| 20 |
+
Intellectual Property. Zope Corporation is a sponsoring member of
|
| 21 |
+
the PSF.
|
| 22 |
+
|
| 23 |
+
All Python releases are Open Source (see http://www.opensource.org for
|
| 24 |
+
the Open Source Definition). Historically, most, but not all, Python
|
| 25 |
+
releases have also been GPL-compatible; the table below summarizes
|
| 26 |
+
the various releases.

Footnotes:

|

+
(1) GPL-compatible doesn't mean that we're distributing Python under
|
| 76 |
+
the GPL. All Python licenses, unlike the GPL, let you distribute
|
| 77 |
+
a modified version without making your changes open source. The
|
| 78 |
+
GPL-compatible licenses make it possible to combine Python with
|
| 79 |
+
other software that is released under the GPL; the others don't.
|
| 80 |
+
|
| 81 |
+
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
|
| 82 |
+
because its license has a choice of law clause. According to
|
| 83 |
+
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
|
| 84 |
+
is "not incompatible" with the GPL.
|
| 85 |
+
|
| 86 |
+
Thanks to the many outside volunteers who have worked under Guido's
|
| 87 |
+
direction to make these releases possible.

|
| 43 |
+
represent, as a whole, an original work of authorship. For the purposes
|
| 44 |
+
of this License, Derivative Works shall not include works that remain
|
| 45 |
+
separable from, or merely link (or bind by name) to the interfaces of,
|
| 46 |
+
the Work and Derivative Works thereof.
|
| 47 |
+
|
| 48 |
+
"Contribution" shall mean any work of authorship, including
|
| 49 |
+
the original version of the Work and any modifications or additions
|
| 50 |
+
to that Work or Derivative Works thereof, that is intentionally

+
submitted to Licensor for inclusion in the Work by the copyright owner
|
| 52 |
+
or by an individual or Legal Entity authorized to submit on behalf of
|
| 53 |
+
the copyright owner. For the purposes of this definition, "submitted"
|
| 54 |
+
means any form of electronic, verbal, or written communication sent
|
| 55 |
+
to the Licensor or its representatives, including but not limited to
|
| 56 |

|
| 57 |
+
and issue tracking systems that are managed by, or on behalf of, the
|
| 58 |
+
Licensor for the purpose of discussing and improving the Work, but
|
| 59 |
+
excluding communication that is conspicuously marked or otherwise
|
| 60 |
+
designated in writing by the copyright owner as "Not a Contribution."
|
| 61 |
+
|
| 62 |
+
"Contributor" shall mean Licensor and any individual or Legal Entity
|
| 63 |
+
on behalf of whom a Contribution has been received by Licensor and
|
| 64 |
+
subsequently incorporated within the Work.
|
| 65 |
+
|
| 66 |
+
2. Grant of Copyright License. Subject to the terms and conditions of
|
| 67 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 68 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 69 |
+
copyright license to reproduce, prepare Derivative Works of,
|
| 70 |
+
publicly display, publicly perform, sublicense, and distribute the
|
| 71 |
+
Work and such Derivative Works in Source or Object form.
|
| 72 |
+
|
| 73 |
+
3. Grant of Patent License. Subject to the terms and conditions of
|
| 74 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 75 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 76 |
+
(except as stated in this section) patent license to make, have made,
|
| 77 |
+
use, offer to sell, sell, import, and otherwise transfer the Work,
|
| 78 |
+
where such license applies only to those patent claims licensable
|
| 79 |
+
by such Contributor that are necessarily infringed by their
|
| 80 |
+
Contribution(s) alone or by combination of their Contribution(s)
|
| 81 |
+
with the Work to which such Contribution(s) was submitted. If You
|
| 82 |
+
institute patent litigation against any entity (including a
|
| 83 |
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
| 84 |
+
or a Contribution incorporated within the Work constitutes direct
|
| 85 |
+
or contributory patent infringement, then any patent licenses
|
| 86 |
+
granted to You under this License for that Work shall terminate
|
| 87 |
+
as of the date such litigation is filed.
|
| 88 |
+
|
| 89 |
+
4. Redistribution. You may reproduce and distribute copies of the
|
| 90 |
+
Work or Derivative Works thereof in any medium, with or without
|
| 91 |
+
modifications, and in Source or Object form, provided that You
|
| 92 |
+
meet the following conditions:
|
| 93 |
+
|
| 94 |
+
(a) You must give any other recipients of the Work or
|
| 95 |
+
Derivative Works a copy of this License; and
|
| 96 |
+
|
| 97 |
+
(b) You must cause any modified files to carry prominent notices
|
| 98 |
+
stating that You changed the files; and
|
| 99 |
+
|
| 100 |
+
(c) You must retain, in the Source form of any Derivative Works
|
| 101 |
+
that You distribute, all copyright, patent, trademark, and
|
| 102 |
+
attribution notices from the Source form of the Work,
|
| 103 |
+
excluding those notices that do not pertain to any part of
|
| 104 |
+
the Derivative Works; and
|
| 105 |
+
|
| 106 |
+
(d) If the Work includes a "NOTICE" text file as part of its
|
| 107 |
+
distribution, then any Derivative Works that You distribute must
|
| 108 |
+
include a readable copy of the attribution notices contained
|
| 109 |
+
within such NOTICE file, excluding those notices that do not
|
| 110 |
+
pertain to any part of the Derivative Works, in at least one
|
| 111 |
+
of the following places: within a NOTICE text file distributed
|
| 112 |
+
as part of the Derivative Works; within the Source form or
|
| 113 |
+
documentation, if provided along with the Derivative Works; or,
|
| 114 |
+
within a display generated by the Derivative Works, if and
|
| 115 |
+
wherever such third-party notices normally appear. The contents
|
| 116 |
+
of the NOTICE file are for informational purposes only and
|
| 117 |
+
do not modify the License. You may add Your own attribution
|
| 118 |
+
notices within Derivative Works that You distribute, alongside
|
| 119 |
+
or as an addendum to the NOTICE text from the Work, provided
|
| 120 |
+
that such additional attribution notices cannot be construed
|
| 121 |
+
as modifying the License.
|
| 122 |
+
|
| 123 |
+
You may add Your own copyright statement to Your modifications and
|
| 124 |
+
may provide additional or different license terms and conditions
|
| 125 |
+
for use, reproduction, or distribution of Your modifications, or
|
| 126 |
+
for any such Derivative Works as a whole, provided Your use,
|
| 127 |
+
reproduction, and distribution of the Work otherwise complies with
|
| 128 |
+
the conditions stated in this License.
|
| 129 |
+
|
| 130 |
+
5. Submission of Contributions. Unless You explicitly state otherwise,
|
| 131 |
+
any Contribution intentionally submitted for inclusion in the Work
|
| 132 |
+
by You to the Licensor shall be under the terms and conditions of
|
| 133 |
+
this License, without any additional terms or conditions.
|
| 134 |
+
Notwithstanding the above, nothing herein shall supersede or modify
|
| 135 |
+
the terms of any separate license agreement you may have executed
|
| 136 |
+
with Licensor regarding such Contributions.
|
| 137 |
+
|
| 138 |
+
6. Trademarks. This License does not grant permission to use the trade
|
| 139 |
+
names, trademarks, service marks, or product names of the Licensor,
|
| 140 |
+
except as required for reasonable and customary use in describing the
|
| 141 |
+
origin of the Work and reproducing the content of the NOTICE file.
|
| 142 |
+
|
| 143 |
+
7. Disclaimer of Warranty. Unless required by applicable law or
|
| 144 |
+
agreed to in writing, Licensor provides the Work (and each
|
| 145 |
+
Contributor provides its Contributions) on an "AS IS" BASIS,
|
| 146 |
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
| 147 |
+
implied, including, without limitation, any warranties or conditions
|
| 148 |
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
| 149 |
+
PARTICULAR PURPOSE. You are solely responsible for determining the
|
| 150 |
+
appropriateness of using or redistributing the Work and assume any
|
| 151 |
+
risks associated with Your exercise of permissions under this License.
|
| 152 |
+
|
| 153 |
+
8. Limitation of Liability. In no event and under no legal theory,
|
| 154 |
+
whether in tort (including negligence), contract, or otherwise,
|
| 155 |
+
unless required by applicable law (such as deliberate and grossly
|
| 156 |
+
negligent acts) or agreed to in writing, shall any Contributor be
|
| 157 |
+
liable to You for damages, including any direct, indirect, special,
|
| 158 |
+
incidental, or consequential damages of any character arising as a
|
| 159 |
+
result of this License or out of the use or inability to use the
|
| 160 |
+
Work (including but not limited to damages for loss of goodwill,
|
| 161 |
+
work stoppage, computer failure or malfunction, or any and all
|
| 162 |
+
other commercial damages or losses), even if such Contributor
|
| 163 |
+
has been advised of the possibility of such damages.
|
| 164 |
+
|
| 165 |
+
9. Accepting Warranty or Additional Liability. While redistributing
|
| 166 |
+
the Work or Derivative Works thereof, You may choose to offer,
|
| 167 |
+
and charge a fee for, acceptance of support, warranty, indemnity,
|
| 168 |
+
or other liability obligations and/or rights consistent with this
|
| 169 |
+
License. However, in accepting such obligations, You may act only
|
| 170 |
+
on Your own behalf and on Your sole responsibility, not on behalf
|
| 171 |
+
of any other Contributor, and only if You agree to indemnify,
|
| 172 |
+
defend, and hold each Contributor harmless for any liability
|
| 173 |
+
incurred by, or claims asserted against, such Contributor by reason
|
| 174 |
+
of your accepting any such warranty or additional liability.
|
| 175 |
+
|
| 176 |
+
END OF TERMS AND CONDITIONS
|

|
| 179 |
+
|
| 180 |
+
To apply the Apache License to your work, attach the following
|
| 181 |

|
| 185 |
+

+
same "printed page" as the copyright notice for easier
|
| 187 |
+
identification within third-party archives.

"Licensor" shall mean the copyright owner or entity authorized by

the copyright owner that is granting the License.

+
direction or management of such entity, whether by contract or

including but not limited to software source code, documentation
|
| 29 |
+
source, and configuration files.
|

|
| 35 |
+
|

|
| 44 |
+
represent, as a whole, an original work of authorship. For the purposes
|
| 45 |
+
of this License, Derivative Works shall not include works that remain
|
| 46 |
+
separable from, or merely link (or bind by name) to the interfaces of,
|
| 47 |
+
the Work and Derivative Works thereof.
|
| 48 |
+
|
| 49 |
+
"Contribution" shall mean any work of authorship, including
|
| 50 |
+
the original version of the Work and any modifications or additions
|
| 51 |
+
to that Work or Derivative Works thereof, that is intentionally

| 52 |
+
submitted to Licensor for inclusion in the Work by the copyright owner
|
| 53 |
+
or by an individual or Legal Entity authorized to submit on behalf of
|
| 54 |
+
the copyright owner. For the purposes of this definition, "submitted"
|
| 55 |
+
means any form of electronic, verbal, or written communication sent
|
| 56 |
+
to the Licensor or its representatives, including but not limited to
|
| 57 |

|
| 58 |
+
and issue tracking systems that are managed by, or on behalf of, the
|
| 59 |
+
Licensor for the purpose of discussing and improving the Work, but
|
| 60 |
+
excluding communication that is conspicuously marked or otherwise

| 61 |
+
designated in writing by the copyright owner as "Not a Contribution."
|
| 62 |
+
|
| 63 |
+
"Contributor" shall mean Licensor and any individual or Legal Entity
|
| 64 |
+
on behalf of whom a Contribution has been received by Licensor and
|
| 65 |
+
subsequently incorporated within the Work.
|
| 66 |
+
|
| 67 |
+
2. Grant of Copyright License. Subject to the terms and conditions of
|
| 68 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 69 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 70 |
+
copyright license to reproduce, prepare Derivative Works of,
|
| 71 |
+
publicly display, publicly perform, sublicense, and distribute the
|
| 72 |
+
Work and such Derivative Works in Source or Object form.
|
| 73 |
+
|
| 74 |
+
3. Grant of Patent License. Subject to the terms and conditions of
|
| 75 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 76 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 77 |
+
(except as stated in this section) patent license to make, have made,
|
| 78 |
+
use, offer to sell, sell, import, and otherwise transfer the Work,
|
| 79 |
+
where such license applies only to those patent claims licensable
|
| 80 |
+
by such Contributor that are necessarily infringed by their
|
| 81 |
+
Contribution(s) alone or by combination of their Contribution(s)
|
| 82 |
+
with the Work to which such Contribution(s) was submitted. If You
|
| 83 |
+
institute patent litigation against any entity (including a
|
| 84 |
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
| 85 |
+
or a Contribution incorporated within the Work constitutes direct
|
| 86 |
+
or contributory patent infringement, then any patent licenses
|
| 87 |
+
granted to You under this License for that Work shall terminate
|
| 88 |
+
as of the date such litigation is filed.
|
| 89 |
+
|
| 90 |
+
4. Redistribution. You may reproduce and distribute copies of the
|
| 91 |
+
Work or Derivative Works thereof in any medium, with or without
|
| 92 |
+
modifications, and in Source or Object form, provided that You
|
| 93 |
+
meet the following conditions:
|
| 94 |
+
|
| 95 |
+
(a) You must give any other recipients of the Work or
|
| 96 |
+
Derivative Works a copy of this License; and
|
| 97 |
+
|
| 98 |
+
(b) You must cause any modified files to carry prominent notices
|
| 99 |
+
stating that You changed the files; and
|
| 100 |
+
|
| 101 |
+
(c) You must retain, in the Source form of any Derivative Works
|
| 102 |
+
that You distribute, all copyright, patent, trademark, and
|
| 103 |
+
attribution notices from the Source form of the Work,
|
| 104 |
+
excluding those notices that do not pertain to any part of
|
| 105 |
+
the Derivative Works; and
|
| 106 |
+
|
| 107 |
+
(d) If the Work includes a "NOTICE" text file as part of its
|
| 108 |
+
distribution, then any Derivative Works that You distribute must
|
| 109 |
+
include a readable copy of the attribution notices contained
|
| 110 |
+
within such NOTICE file, excluding those notices that do not
|
| 111 |
+
pertain to any part of the Derivative Works, in at least one
|
| 112 |
+
of the following places: within a NOTICE text file distributed
|
| 113 |
+
as part of the Derivative Works; within the Source form or
|
| 114 |
+
documentation, if provided along with the Derivative Works; or,
|
| 115 |
+
within a display generated by the Derivative Works, if and
|
| 116 |
+
wherever such third-party notices normally appear. The contents
|
| 117 |
+
of the NOTICE file are for informational purposes only and
|
| 118 |
+
do not modify the License. You may add Your own attribution
|
| 119 |
+
notices within Derivative Works that You distribute, alongside
|
| 120 |
+
or as an addendum to the NOTICE text from the Work, provided
|
| 121 |
+
that such additional attribution notices cannot be construed
|
| 122 |
+
as modifying the License.
|
| 123 |
+
|
| 124 |
+
You may add Your own copyright statement to Your modifications and
|
| 125 |
+
may provide additional or different license terms and conditions
|
| 126 |
+
for use, reproduction, or distribution of Your modifications, or
|
| 127 |
+
for any such Derivative Works as a whole, provided Your use,
|
| 128 |
+
reproduction, and distribution of the Work otherwise complies with
|
| 129 |
+
the conditions stated in this License.
|
| 130 |
+
|
| 131 |
+
5. Submission of Contributions. Unless You explicitly state otherwise,
|
| 132 |
+
any Contribution intentionally submitted for inclusion in the Work
|
| 133 |
+
by You to the Licensor shall be under the terms and conditions of
|
| 134 |
+
this License, without any additional terms or conditions.
|
| 135 |
+
Notwithstanding the above, nothing herein shall supersede or modify
|
| 136 |
+
the terms of any separate license agreement you may have executed
|
| 137 |
+
with Licensor regarding such Contributions.
|
| 138 |
+
|
| 139 |
+
6. Trademarks. This License does not grant permission to use the trade
|
| 140 |
+
names, trademarks, service marks, or product names of the Licensor,
|
| 141 |
+
except as required for reasonable and customary use in describing the
|
| 142 |
+
origin of the Work and reproducing the content of the NOTICE file.
|
| 143 |
+
|
| 144 |
+
7. Disclaimer of Warranty. Unless required by applicable law or
|
| 145 |
+
agreed to in writing, Licensor provides the Work (and each
|
| 146 |
+
Contributor provides its Contributions) on an "AS IS" BASIS,
|
| 147 |
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
| 148 |
+
implied, including, without limitation, any warranties or conditions
|
| 149 |
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
| 150 |
+
PARTICULAR PURPOSE. You are solely responsible for determining the
|
| 151 |
+
appropriateness of using or redistributing the Work and assume any
|
| 152 |
+
risks associated with Your exercise of permissions under this License.
|
| 153 |
+
|
| 154 |
+
8. Limitation of Liability. In no event and under no legal theory,
|
| 155 |
+
whether in tort (including negligence), contract, or otherwise,
|
| 156 |
+
unless required by applicable law (such as deliberate and grossly
|
| 157 |
+
negligent acts) or agreed to in writing, shall any Contributor be
|
| 158 |
+
liable to You for damages, including any direct, indirect, special,
|
| 159 |
+
incidental, or consequential damages of any character arising as a
|
| 160 |
+
result of this License or out of the use or inability to use the
|
| 161 |
+
Work (including but not limited to damages for loss of goodwill,
|
| 162 |
+
work stoppage, computer failure or malfunction, or any and all
|
| 163 |
+
other commercial damages or losses), even if such Contributor
|
| 164 |
+
has been advised of the possibility of such damages.
|
| 165 |
+
|
| 166 |
+
9. Accepting Warranty or Additional Liability. While redistributing
|
| 167 |
+
the Work or Derivative Works thereof, You may choose to offer,
|
| 168 |
+
and charge a fee for, acceptance of support, warranty, indemnity,
|
| 169 |
+
or other liability obligations and/or rights consistent with this
|
| 170 |
+
License. However, in accepting such obligations, You may act only
|
| 171 |
+
on Your own behalf and on Your sole responsibility, not on behalf
|
| 172 |
+
of any other Contributor, and only if You agree to indemnify,
|
| 173 |
+
defend, and hold each Contributor harmless for any liability
|
| 174 |
+
incurred by, or claims asserted against, such Contributor by reason
|
| 175 |
+
of your accepting any such warranty or additional liability.
|
| 176 |
+
|
| 177 |
+

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
| 7 |
+
|
| 8 |
+
1. Definitions.
|
| 9 |
+
|
| 10 |
+

|
| 11 |
+
and distribution as defined by Sections 1 through 9 of this document.
|
| 12 |

|
| 13 |
+
"Licensor" shall mean the copyright owner or entity authorized by
|
| 14 |
+
the copyright owner that is granting the License.
|
| 15 |
+
|
| 16 |

"Legal Entity" shall mean the union of the acting entity and all
|
| 17 |

other entities that control, are controlled by, or are under common

control with that entity. For the purposes of this definition,
|
| 19 |
+

|
| 20 |
+
direction or management of such entity, whether by contract or
|

|
| 28 |
+
including but not limited to software source code, documentation
|
| 29 |
+
source, and configuration files.
|
| 30 |
+
|
| 31 |

+
and conversions to other media types.
|
| 35 |
+
|
| 36 |
+
"Work" shall mean the work of authorship, whether in Source or
|
| 37 |

+
|

form, that is based on (or derived from) the Work and for which the
|

|
| 44 |
+
represent, as a whole, an original work of authorship. For the purposes
|
| 45 |
+
of this License, Derivative Works shall not include works that remain
|
| 46 |
+
separable from, or merely link (or bind by name) to the interfaces of,
|
| 47 |
+
the Work and Derivative Works thereof.
|
| 48 |
+
|
| 49 |
+
"Contribution" shall mean any work of authorship, including
|
| 50 |
+
the original version of the Work and any modifications or additions
|
| 51 |
+
to that Work or Derivative Works thereof, that is intentionally
|
| 52 |
+
submitted to Licensor for inclusion in the Work by the copyright owner
|
| 53 |
+
or by an individual or Legal Entity authorized to submit on behalf of
|
| 54 |
+
the copyright owner. For the purposes of this definition, "submitted"
|
| 55 |
+
means any form of electronic, verbal, or written communication sent
|
| 56 |
+
to the Licensor or its representatives, including but not limited to
|
| 57 |
+
communication on electronic mailing lists, source code control systems,
|
| 58 |
+
and issue tracking systems that are managed by, or on behalf of, the
|
| 59 |
+
Licensor for the purpose of discussing and improving the Work, but
|
| 60 |
+
excluding communication that is conspicuously marked or otherwise
|
| 61 |
+
designated in writing by the copyright owner as "Not a Contribution."
|
| 62 |
+
|
| 63 |
+
"Contributor" shall mean Licensor and any individual or Legal Entity
|
| 64 |
+
on behalf of whom a Contribution has been received by Licensor and
|
| 65 |
+
subsequently incorporated within the Work.
|
| 66 |
+
|
| 67 |
+
2. Grant of Copyright License. Subject to the terms and conditions of
|
| 68 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 69 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 70 |
+
copyright license to reproduce, prepare Derivative Works of,
|
| 71 |
+
publicly display, publicly perform, sublicense, and distribute the
|
| 72 |
+
Work and such Derivative Works in Source or Object form.
|
| 73 |
+
|
| 74 |
+
3. Grant of Patent License. Subject to the terms and conditions of
|
| 75 |
+
this License, each Contributor hereby grants to You a perpetual,
|
| 76 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
| 77 |
+
(except as stated in this section) patent license to make, have made,
|
| 78 |
+
use, offer to sell, sell, import, and otherwise transfer the Work,
|
| 79 |
+
where such license applies only to those patent claims licensable
|
| 80 |
+
by such Contributor that are necessarily infringed by their
|
| 81 |
+
Contribution(s) alone or by combination of their Contribution(s)
|
| 82 |
+
with the Work to which such Contribution(s) was submitted. If You
|
| 83 |
+
institute patent litigation against any entity (including a
|
| 84 |
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
| 85 |
+
or a Contribution incorporated within the Work constitutes direct
|
| 86 |
+
or contributory patent infringement, then any patent licenses
|
| 87 |
+
granted to You under this License for that Work shall terminate
|
| 88 |
+
as of the date such litigation is filed.
|
| 89 |
+
|
| 90 |
+
4. Redistribution. You may reproduce and distribute copies of the
|
| 91 |
+
Work or Derivative Works thereof in any medium, with or without
|
| 92 |
+
modifications, and in Source or Object form, provided that You
|
| 93 |
+
meet the following conditions:
|
| 94 |
+
|
| 95 |
+
(a) You must give any other recipients of the Work or
|
| 96 |
+
Derivative Works a copy of this License; and
|
| 97 |
+
|
| 98 |
+
(b) You must cause any modified files to carry prominent notices
|
| 99 |
+
stating that You changed the files; and
|
| 100 |
+
|
| 101 |
+
(c) You must retain, in the Source form of any Derivative Works
|
| 102 |
+
that You distribute, all copyright, patent, trademark, and
|
| 103 |
+
attribution notices from the Source form of the Work,
|
| 104 |
+
excluding those notices that do not pertain to any part of
|
| 105 |
+
the Derivative Works; and
|
| 106 |
+
|
| 107 |
+
(d) If the Work includes a "NOTICE" text file as part of its
|
| 108 |
+
distribution, then any Derivative Works that You distribute must
|
| 109 |
+
include a readable copy of the attribution notices contained
|
| 110 |
+
within such NOTICE file, excluding those notices that do not
|
| 111 |
+
pertain to any part of the Derivative Works, in at least one
|
| 112 |
+
of the following places: within a NOTICE text file distributed
|
| 113 |
+
as part of the Derivative Works; within the Source form or
|
| 114 |
+
documentation, if provided along with the Derivative Works; or,
|
| 115 |
+
within a display generated by the Derivative Works, if and
|
| 116 |
+
wherever such third-party notices normally appear. The contents
|
| 117 |
+
of the NOTICE file are for informational purposes only and
|
| 118 |
+
do not modify the License. You may add Your own attribution
|
| 119 |
+
notices within Derivative Works that You distribute, alongside
|
| 120 |
+
or as an addendum to the NOTICE text from the Work, provided
|
| 121 |
+
that such additional attribution notices cannot be construed
|
| 122 |
+
as modifying the License.
|
| 123 |
+
|
| 124 |
+
You may add Your own copyright statement to Your modifications and
|
| 125 |
+
may provide additional or different license terms and conditions
|
| 126 |
+
for use, reproduction, or distribution of Your modifications, or
|
| 127 |
+
for any such Derivative Works as a whole, provided Your use,
|
| 128 |
+
reproduction, and distribution of the Work otherwise complies with
|
| 129 |
+
the conditions stated in this License.
|
| 130 |
+
|
| 131 |
+
5. Submission of Contributions. Unless You explicitly state otherwise,
|
| 132 |
+
any Contribution intentionally submitted for inclusion in the Work
|
| 133 |
+
by You to the Licensor shall be under the terms and conditions of
|
| 134 |
+
this License, without any additional terms or conditions.
|
| 135 |
+
Notwithstanding the above, nothing herein shall supersede or modify
|
| 136 |
+
the terms of any separate license agreement you may have executed
|
| 137 |
+
with Licensor regarding such Contributions.
|
| 138 |
+
|
| 139 |
+
6. Trademarks. This License does not grant permission to use the trade
|
| 140 |
+
names, trademarks, service marks, or product names of the Licensor,
|
| 141 |
+
except as required for reasonable and customary use in describing the
|
| 142 |
+
origin of the Work and reproducing the content of the NOTICE file.
|
| 143 |
+
|
| 144 |
+
7. Disclaimer of Warranty. Unless required by applicable law or
|
| 145 |
+
agreed to in writing, Licensor provides the Work (and each
|
| 146 |
+
Contributor provides its Contributions) on an "AS IS" BASIS,
|
| 147 |
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
| 148 |
+
implied, including, without limitation, any warranties or conditions
|
| 149 |
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
| 150 |
+
PARTICULAR PURPOSE. You are solely responsible for determining the
|
| 151 |
+
appropriateness of using or redistributing the Work and assume any
|
| 152 |
+
risks associated with Your exercise of permissions under this License.
|
| 153 |
+
|
| 154 |
+
8. Limitation of Liability. In no event and under no legal theory,
|
| 155 |
+
whether in tort (including negligence), contract, or otherwise,
|
| 156 |
+
unless required by applicable law (such as deliberate and grossly
|
| 157 |
+
negligent acts) or agreed to in writing, shall any Contributor be
|
| 158 |
+
liable to You for damages, including any direct, indirect, special,
|
| 159 |
+
incidental, or consequential damages of any character arising as a
|
| 160 |
+
result of this License or out of the use or inability to use the
|
| 161 |
+
Work (including but not limited to damages for loss of goodwill,
|
| 162 |
+
work stoppage, computer failure or malfunction, or any and all
|
| 163 |
+
other commercial damages or losses), even if such Contributor
|
| 164 |
+
has been advised of the possibility of such damages.
|
| 165 |
+
|
| 166 |
+
9. Accepting Warranty or Additional Liability. While redistributing
|
| 167 |
+
the Work or Derivative Works thereof, You may choose to offer,
|
| 168 |
+
and charge a fee for, acceptance of support, warranty, indemnity,
|
| 169 |
+
or other liability obligations and/or rights consistent with this
|
| 170 |
+
License. However, in accepting such obligations, You may act only
|
| 171 |
+
on Your own behalf and on Your sole responsibility, not on behalf
|
| 172 |
+
of any other Contributor, and only if You agree to indemnify,
|
| 173 |
+
defend, and hold each Contributor harmless for any liability
|
| 174 |
+
incurred by, or claims asserted against, such Contributor by reason
|
| 175 |
+
of your accepting any such warranty or additional liability.

Rationale
|
| 24 |
+
=========
|
| 25 |
+
|
| 26 |
+
Historically pip has not had any dependencies except for ``setuptools`` itself,
|
| 27 |
+
choosing instead to implement any functionality it needed to prevent needing
|
| 28 |
+
a dependency. However, starting with pip 1.5, we began to replace code that was
|
| 29 |
+
implemented inside of pip with reusable libraries from PyPI. This brought the
|
| 30 |
+
typical benefits of reusing libraries instead of reinventing the wheel like
|
| 31 |
+
higher quality and more battle tested code, centralization of bug fixes
|
| 32 |
+
(particularly security sensitive ones), and better/more features for less work.
|
| 33 |
+
|
| 34 |
+
However, there are several issues with having dependencies in the traditional
|
| 35 |
+
way (via ``install_requires``) for pip. These issues are:
|
| 36 |
+
|
| 37 |
+
**Fragility**
|
| 38 |
+
When pip depends on another library to function then if for whatever reason
|
| 39 |
+
that library either isn't installed or an incompatible version is installed
|
| 40 |
+
then pip ceases to function. This is of course true for all Python
|
| 41 |
+
applications, however for every application *except* for pip the way you fix
|
| 42 |
+
it is by re-running pip. Obviously, when pip can't run, you can't use pip to
|
| 43 |
+
fix pip, so you're left having to manually resolve dependencies and
|
| 44 |
+
installing them by hand.
|
| 45 |
+
|
| 46 |
+
**Making other libraries uninstallable**
|
| 47 |
+
One of pip's current dependencies is the ``requests`` library, for which pip
|
| 48 |
+
requires a fairly recent version to run. If pip depended on ``requests`` in
|
| 49 |
+
the traditional manner, then we'd either have to maintain compatibility with
|
| 50 |
+
every ``requests`` version that has ever existed (and ever will), OR allow
|
| 51 |
+
pip to render certain versions of ``requests`` uninstallable. (The second
|
| 52 |
+
issue, although technically true for any Python application, is magnified by
|
| 53 |
+
pip's ubiquity; pip is installed by default in Python, in ``pyvenv``, and in
|
| 54 |
+
``virtualenv``.)
|
| 55 |
+
|
| 56 |
+
**Security**
|
| 57 |
+
This might seem puzzling at first glance, since vendoring has a tendency to
|
| 58 |
+
complicate updating dependencies for security updates, and that holds true
|
| 59 |
+
for pip. However, given the *other* reasons for avoiding dependencies, the
|
| 60 |
+
alternative is for pip to reinvent the wheel itself. This is what pip did
|
| 61 |
+
historically. It forced pip to re-implement its own HTTPS verification
|
| 62 |
+
routines as a workaround for the Python standard library's lack of SSL
|
| 63 |
+
validation, which resulted in similar bugs in the validation routine in
|
| 64 |
+
``requests`` and ``urllib3``, except that they had to be discovered and
|
| 65 |
+
fixed independently. Even though we're vendoring, reusing libraries keeps
|
| 66 |
+
pip more secure by relying on the great work of our dependencies, *and*
|
| 67 |
+
allowing for faster, easier security fixes by simply pulling in newer
|
| 68 |
+
versions of dependencies.
|
| 69 |
+
|
| 70 |
+
**Bootstrapping**
|
| 71 |
+
Currently most popular methods of installing pip rely on pip's
|
| 72 |
+
self-contained nature to install pip itself. These tools work by bundling a
|
| 73 |
+
copy of pip, adding it to ``sys.path``, and then executing that copy of pip.
|
| 74 |
+
This is done instead of implementing a "mini installer" (to reduce
|
| 75 |
+
duplication); pip already knows how to install a Python package, and is far
|
| 76 |
+
more battle-tested than any "mini installer" could ever possibly be.
|
| 77 |
+
|
| 78 |
+
Many downstream redistributors have policies against this kind of bundling, and
|
| 79 |
+
instead opt to patch the software they distribute to debundle it and make it
|
| 80 |
+
rely on the global versions of the software that they already have packaged
|
| 81 |
+
(which may have its own patches applied to it). We (the pip team) would prefer
|
| 82 |
+
it if pip was *not* debundled in this manner due to the above reasons and
|
| 83 |
+
instead we would prefer it if pip would be left intact as it is now.
|
| 84 |
+
|
| 85 |
+
In the longer term, if someone has a *portable* solution to the above problems,
|
| 86 |
+
other than the bundling method we currently use, that doesn't add additional
|
| 87 |
+
problems that are unreasonable then we would be happy to consider, and possibly
|
| 88 |
+
switch to said method. This solution must function correctly across all of the
|
| 89 |
+
situation that we expect pip to be used and not mandate some external mechanism
|
| 90 |
+
such as OS packages.
|
| 91 |
+
|
| 92 |
+
|
| 93 |
+
Modifications
|
| 94 |
+
=============
|
| 95 |
+
|
| 96 |
+
* ``setuptools`` is completely stripped to only keep ``pkg_resources``.
|
| 97 |
+
* ``pkg_resources`` has been modified to import its dependencies from
|
| 98 |
+
``pip._vendor``, and to use the vendored copy of ``platformdirs``
|
| 99 |
+
rather than ``appdirs``.
|
| 100 |
+
* ``packaging`` has been modified to import its dependencies from
|
| 101 |
+
``pip._vendor``.
|
| 102 |
+
* ``CacheControl`` has been modified to import its dependencies from
|
| 103 |
+
``pip._vendor``.
|
| 104 |
+
* ``requests`` has been modified to import its other dependencies from
|
| 105 |
+
``pip._vendor`` and to *not* load ``simplejson`` (all platforms) and
|
| 106 |
+
``pyopenssl`` (Windows).
|
| 107 |
+
* ``platformdirs`` has been modified to import its submodules from ``pip._vendor.platformdirs``.
|
| 108 |
+
|
| 109 |
+
Automatic Vendoring
|
| 110 |
+
===================
|
| 111 |
+
|
| 112 |
+
Vendoring is automated via the `vendoring <https://pypi.org/project/vendoring/>`_ tool from the content of
|
| 113 |
+
``pip/_vendor/vendor.txt`` and the different patches in
|
| 114 |
+
``tools/vendoring/patches``.
|
| 115 |
+
Launch it via ``vendoring sync . -v`` (requires ``vendoring>=0.2.2``).
|
| 116 |
+
Tool configuration is done via ``pyproject.toml``.
|
| 117 |
+
|
| 118 |
+
To update the vendored library versions, we have a session defined in ``nox``.
|
| 119 |
+
The command to upgrade everything is::
|
| 120 |
+
|
| 121 |
+
nox -s vendoring -- --upgrade-all --skip setuptools
|
| 122 |
+
|
| 123 |
+
We do not upgrade ``setuptools``, because we only rely on ``pkg_resources``,
|
| 124 |
+
and tracking every ``setuptools`` change is unnecessary for our needs.
|
| 125 |
+
|
| 126 |
+
|
| 127 |
+
Managing Local Patches
|
| 128 |
+
======================
|
| 129 |
+
|
| 130 |
+
The ``vendoring`` tool automatically applies our local patches, but updating,
|
| 131 |
+
the patches sometimes no longer apply cleanly. In that case, the update will
|
| 132 |
+
fail. To resolve this, take the following steps:
|
| 133 |
+
|
| 134 |
+
1. Revert any incomplete changes in the revendoring branch, to ensure you have
|
| 135 |
+
a clean starting point.
|
| 136 |
+
2. Run the revendoring of the library with a problem again: ``nox -s vendoring
|
| 137 |
+
-- --upgrade <library_name>``.
|
| 138 |
+
3. This will fail again, but you will have the original source in your working
|
| 139 |
+
directory. Review the existing patch against the source, and modify the patch
|
| 140 |
+
to reflect the new version of the source. If you ``git add`` the changes the
|
| 141 |
+
vendoring made, you can modify the source to reflect the patch file and then
|
| 142 |
+
generate a new patch with ``git diff``.
|
| 143 |
+
4. Now, revert everything *except* the patch file changes. Leave the modified
|
| 144 |
+
patch file unstaged but saved in the working tree.
|
| 145 |
+
5. Re-run the vendoring. This time, it should pick up the changed patch file
|
| 146 |
+
and apply it cleanly. The patch file changes will be committed along with the
|
| 147 |
+
revendoring, so the new commit should be ready to test and publish as a PR.
|
| 148 |
+
|
| 149 |
+
|
| 150 |
+
Debundling
|
| 151 |
+
==========
|
| 152 |
+
|
| 153 |
+
As mentioned in the rationale, we, the pip team, would prefer it if pip was not
|
| 154 |
+
debundled (other than optionally ``pip/_vendor/requests/cacert.pem``) and that
|
| 155 |
+
pip was left intact. However, if you insist on doing so, we have a
|
| 156 |
+
semi-supported method (that we don't test in our CI) and requires a bit of
|
| 157 |
+
extra work on your end in order to solve the problems described above.
|
| 158 |
+
|
| 159 |
+
1. Delete everything in ``pip/_vendor/`` **except** for
|
| 160 |
+
``pip/_vendor/__init__.py`` and ``pip/_vendor/vendor.txt``.
|
| 161 |
+
2. Generate wheels for each of pip's dependencies (and any of their
|
| 162 |
+
dependencies) using your patched copies of these libraries. These must be
|
| 163 |
+
placed somewhere on the filesystem that pip can access (``pip/_vendor`` is
|
| 164 |
+
the default assumption).
|
| 165 |
+
3. Modify ``pip/_vendor/__init__.py`` so that the ``DEBUNDLED`` variable is
|
| 166 |
+
``True``.
|
| 167 |
+
4. Upon installation, the ``INSTALLER`` file in pip's own ``dist-info``
|
| 168 |
+
directory should be set to something other than ``pip``, so that pip
|
| 169 |
+
can detect that it wasn't installed using itself.
|
| 170 |
+
5. *(optional)* If you've placed the wheels in a location other than
|
| 171 |
+
``pip/_vendor/``, then modify ``pip/_vendor/__init__.py`` so that the
|
| 172 |
+
``WHEEL_DIR`` variable points to the location you've placed them.
|
| 173 |
+
6. *(optional)* Update the ``pip_self_version_check`` logic to use the
|
| 174 |
+
appropriate logic for determining the latest available version of pip and
|
| 175 |
+
prompt the user with the correct upgrade message.
|
| 176 |
+
|
| 177 |
+
Note that partial debundling is **NOT** supported. You need to prepare wheels
|
| 178 |
+
for all dependencies for successful debundling.

This package contains a modified version of ca-bundle.crt:
|
| 2 |
+
|
| 3 |
+
ca-bundle.crt -- Bundle of CA Root Certificates
|
| 4 |
+
|
| 5 |
+
This is a bundle of X.509 certificates of public Certificate Authorities
|
| 6 |
+
(CA). These were automatically extracted from Mozilla's root certificates
|
| 7 |
+
file (certdata.txt). This file can be found in the mozilla source tree:
|
| 8 |
+
https://hg.mozilla.org/mozilla-central/file/tip/security/nss/lib/ckfw/builtins/certdata.txt
|
| 9 |
+
It contains the certificates in PEM format and therefore
|
| 10 |
+
can be directly used with curl / libcurl / php_curl, or with
|
| 11 |
+
an Apache+mod_ssl webserver for SSL client authentication.
|
| 12 |
+
Just configure this file as the SSLCACertificateFile.#
