||||
transformation or translation of a Source form, including but |
||||
not limited to compiled object code, generated documentation, |
||||
and conversions to other media types. |
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or |
||||
Object form, made available under the License, as indicated by a |
||||
copyright notice that is included in or attached to the work |
||||
(an example is provided in the Appendix below). |
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object |
||||
form, that is based on (or derived from) the Work and for which the |
||||
editorial revisions, annotations, elaborations, or other modifications |
||||
represent, as a whole, an original work of authorship. For the purposes |
||||
of this License, Derivative Works shall not include works that remain |
||||

||||
the Work and Derivative Works thereof. |
||||
|
||||
"Contribution" shall mean any work of authorship, including |

||||
Licensor for the purpose of discussing and improving the Work, but |

designated in writing by the copyright owner as "Not a Contribution." |
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity |
||||
on behalf of whom a Contribution has been received by Licensor and |
||||
subsequently incorporated within the Work. |
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of |
||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
copyright license to reproduce, prepare Derivative Works of, |
||||
publicly display, publicly perform, sublicense, and distribute the |
||||
Work and such Derivative Works in Source or Object form. |
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of |
||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
(except as stated in this section) patent license to make, have made, |

use, offer to sell, sell, import, and otherwise transfer the Work, |

||||
by such Contributor that are necessarily infringed by their |
||||
Contribution(s) alone or by combination of their Contribution(s) |
||||
with the Work to which such Contribution(s) was submitted. If You |
||||
institute patent litigation against any entity (including a |
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work |
||||
or a Contribution incorporated within the Work constitutes direct |
||||
or contributory patent infringement, then any patent licenses |
||||
granted to You under this License for that Work shall terminate |
||||
as of the date such litigation is filed. |
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the |
||||
Work or Derivative Works thereof in any medium, with or without |
||||
modifications, and in Source or Object form, provided that You |
||||
meet the following conditions: |
||||
|
||||
(a) You must give any other recipients of the Work or |
||||
Derivative Works a copy of this License; and |
||||
|
||||
(b) You must cause any modified files to carry prominent notices |
||||
stating that You changed the files; and |
||||
|
||||

||||
attribution notices from the Source form of the Work, |
||||
excluding those notices that do not pertain to any part of |
||||
the Derivative Works; and |
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its |
||||
distribution, then any Derivative Works that You distribute must |
||||
include a readable copy of the attribution notices contained |
||||
within such NOTICE file, excluding those notices that do not |
||||
pertain to any part of the Derivative Works, in at least one |
||||
of the following places: within a NOTICE text file distributed |
||||
as part of the Derivative Works; within the Source form or |
||||
documentation, if provided along with the Derivative Works; or, |
||||
within a display generated by the Derivative Works, if and |
||||
wherever such third-party notices normally appear. The contents |
||||
of the NOTICE file are for informational purposes only and |
||||
do not modify the License. You may add Your own attribution |
||||
notices within Derivative Works that You distribute, alongside |
||||
or as an addendum to the NOTICE text from the Work, provided |
||||
that such additional attribution notices cannot be construed |
||||
as modifying the License. |
||||
|
||||
You may add Your own copyright statement to Your modifications and |
||||
may provide additional or different license terms and conditions |
||||
for use, reproduction, or distribution of Your modifications, or |
||||
for any such Derivative Works as a whole, provided Your use, |
||||
reproduction, and distribution of the Work otherwise complies with |
||||
the conditions stated in this License. |
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise, |
||||
any Contribution intentionally submitted for inclusion in the Work |
||||
by You to the Licensor shall be under the terms and conditions of |
||||
this License, without any additional terms or conditions. |
||||
Notwithstanding the above, nothing herein shall supersede or modify |
||||
the terms of any separate license agreement you may have executed |
||||
with Licensor regarding such Contributions. |
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade |
||||
names, trademarks, service marks, or product names of the Licensor, |
||||
except as required for reasonable and customary use in describing the |
||||
origin of the Work and reproducing the content of the NOTICE file. |
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or |
||||
agreed to in writing, Licensor provides the Work (and each |
||||
Contributor provides its Contributions) on an "AS IS" BASIS, |
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
||||
implied, including, without limitation, any warranties or conditions |
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |
||||
PARTICULAR PURPOSE. You are solely responsible for determining the |
||||
appropriateness of using or redistributing the Work and assume any |
||||
risks associated with Your exercise of permissions under this License. |
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory, |
||||
whether in tort (including negligence), contract, or otherwise, |
||||
unless required by applicable law (such as deliberate and grossly |
||||
negligent acts) or agreed to in writing, shall any Contributor be |
||||
liable to You for damages, including any direct, indirect, special, |
||||
incidental, or consequential damages of any character arising as a |
||||
result of this License or out of the use or inability to use the |
||||
Work (including but not limited to damages for loss of goodwill, |
||||
work stoppage, computer failure or malfunction, or any and all |
||||
other commercial damages or losses), even if such Contributor |
||||
has been advised of the possibility of such damages. |
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing |
||||
the Work or Derivative Works thereof, You may choose to offer, |
||||
and charge a fee for, acceptance of support, warranty, indemnity, |
||||
or other liability obligations and/or rights consistent with this |
||||
License. However, in accepting such obligations, You may act only |
||||
on Your own behalf and on Your sole responsibility, not on behalf |
||||
of any other Contributor, and only if You agree to indemnify, |
||||
defend, and hold each Contributor harmless for any liability |
||||
incurred by, or claims asserted against, such Contributor by reason |
||||
of your accepting any such warranty or additional liability. |

||||
Version 3, 29 June 2007 |
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
||||
Everyone is permitted to copy and distribute verbatim copies |
||||
of this license document, but changing it is not allowed. |
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates |
||||
the terms and conditions of version 3 of the GNU General Public |
||||
License, supplemented by the additional permissions listed below. |
||||
|
||||
0. Additional Definitions. |
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser |
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU |
||||
General Public License. |
||||
|
||||
"The Library" refers to a covered work governed by this License, |
||||
other than an Application or a Combined Work as defined below. |
||||
|
||||
An "Application" is any work that makes use of an interface provided |
||||
by the Library, but which is not otherwise based on the Library. |
||||
Defining a subclass of a class defined by the Library is deemed a mode |
||||
of using an interface provided by the Library. |
||||
|
||||
A "Combined Work" is a work produced by combining or linking an |
||||
Application with the Library. The particular version of the Library |
||||
with which the Combined Work was made is also called the "Linked |
||||
Version". |
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the |
||||
Corresponding Source for the Combined Work, excluding any source code |
||||
for portions of the Combined Work that, considered in isolation, are |
||||
based on the Application, and not on the Linked Version. |
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the |
||||
object code and/or source code for the Application, including any data |
||||
and utility programs needed for reproducing the Combined Work from the |
||||
Application, but excluding the System Libraries of the Combined Work. |
||||
|
||||
1. Exception to Section 3 of the GNU GPL. |
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License |
||||
without being bound by section 3 of the GNU GPL. |
||||
|
||||
2. Conveying Modified Versions. |
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a |
||||
facility refers to a function or data to be supplied by an Application |
||||
that uses the facility (other than as an argument passed when the |
||||
facility is invoked), then you may convey a copy of the modified |
||||
version: |
||||
|
||||
a) under this License, provided that you make a good faith effort to |
||||
ensure that, in the event an Application does not supply the |
||||
function or data, the facility still operates, and performs |
||||
whatever part of its purpose remains meaningful, or |
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of |
||||
this License applicable to that copy. |
||||
|
||||
3. Object Code Incorporating Material from Library Header Files. |
||||
|
||||
The object code form of an Application may incorporate material from |
||||
a header file that is part of the Library. You may convey such object |
||||
code under terms of your choice, provided that, if the incorporated |
||||
material is not limited to numerical parameters, data structure |
||||
layouts and accessors, or small macros, inline functions and templates |
||||
(ten or fewer lines in length), you do both of the following: |
||||
|
||||
a) Give prominent notice with each copy of the object code that the |
||||
Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
4. Combined Works. |
||||
|
||||
You may convey a Combined Work under terms of your choice that, |
||||
taken together, effectively do not restrict modification of the |
||||
portions of the Library contained in the Combined Work and reverse |
||||
engineering for debugging such modifications, if you also do each of |
||||
the following: |
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that |
||||
the Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
c) For a Combined Work that displays copyright notices during |
||||
execution, include the copyright notice for the Library among |
||||
these notices, as well as a reference directing the user to the |
||||
copies of the GNU GPL and this license document. |
||||
|
||||
d) Do one of the following: |
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this |
||||
License, and the Corresponding Application Code in a form |
||||
suitable for, and under terms that permit, the user to |
||||
recombine or relink the Application with a modified version of |
||||
the Linked Version to produce a modified Combined Work, in the |
||||
manner specified by section 6 of the GNU GPL for conveying |
||||
Corresponding Source. |
||||
|
||||
1) Use a suitable shared library mechanism for linking with the |
||||
Library. A suitable mechanism is one that (a) uses at run time |
||||
a copy of the Library already present on the user's computer |
||||
system, and (b) will operate properly with a modified version |
||||
of the Library that is interface-compatible with the Linked |
||||
Version. |
||||
|
||||
e) Provide Installation Information, but only if you would otherwise |
||||
be required to provide such information under section 6 of the |
||||
GNU GPL, and only to the extent that such information is |
||||
necessary to install and execute a modified version of the |
||||
Combined Work produced by recombining or relinking the |
||||
Application with a modified version of the Linked Version. (If |
||||
you use option 4d0, the Installation Information must accompany |
||||
the Minimal Corresponding Source and Corresponding Application |
||||
Code. If you use option 4d1, you must provide the Installation |
||||
Information in the manner specified by section 6 of the GNU GPL |
||||
for conveying Corresponding Source.) |
||||
|
||||
5. Combined Libraries. |
||||
|
||||
You may place library facilities that are a work based on the |
||||
Library side by side in a single library together with other library |
||||
facilities that are not Applications and are not covered by this |
||||
License, and convey such a combined library under terms of your |
||||
choice, if you do both of the following: |
||||
|
||||
a) Accompany the combined library with a copy of the same work based |
||||
on the Library, uncombined with any other library facilities, |
||||
conveyed under the terms of this License. |
||||
|
||||
b) Give prominent notice with the combined library that part of it |
||||
is a work based on the Library, and explaining where to find the |
||||
accompanying uncombined form of the same work. |
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License. |
||||
|
||||
The Free Software Foundation may publish revised and/or new versions |
||||
of the GNU Lesser General Public License from time to time. Such new |
||||
versions will be similar in spirit to the present version, but may |
||||
differ in detail to address new problems or concerns. |
||||
|
||||
Each version is given a distinguishing version number. If the |
||||
Library as you received it specifies that a certain numbered version |
||||
of the GNU Lesser General Public License "or any later version" |
||||
applies to it, you have the option of following the terms and |
||||
conditions either of that published version or of any later version |
||||
published by the Free Software Foundation. If the Library as you |
||||
received it does not specify a version number of the GNU Lesser |
||||
General Public License, you may choose any version of the GNU Lesser |
||||
General Public License ever published by the Free Software Foundation. |
||||
|
||||
If the Library as you received it specifies that a proxy can decide |
||||
whether future versions of the GNU Lesser General Public License shall |
||||
apply, that proxy's public statement of acceptance of any version is |
||||
permanent authorization for you to choose that version for the |
||||
Library. |

||||
|
||||
The juju/errors provides an easy way to annotate errors without losing the |
||||
orginal error context. |
||||
|
||||
The exported `New` and `Errorf` functions are designed to replace the |
||||
`errors.New` and `fmt.Errorf` functions respectively. The same underlying |
||||
error is there, but the package also records the location at which the error |
||||
was created. |
||||
|
||||
A primary use case for this library is to add extra context any time an |
||||
error is returned from a function. |
||||
|
||||
if err := SomeFunc(); err != nil { |
||||
return err |
||||
} |
||||
|
||||
This instead becomes: |
||||
|
||||
if err := SomeFunc(); err != nil { |
||||
return errors.Trace(err) |
||||
} |
||||
|
||||
which just records the file and line number of the Trace call, or |
||||
|
||||
if err := SomeFunc(); err != nil { |
||||
return errors.Annotate(err, "more context") |
||||
} |
||||
|
||||
which also adds an annotation to the error. |
||||
|
||||
When you want to check to see if an error is of a particular type, a helper |
||||
function is normally exported by the package that returned the error, like the |
||||
`os` package does. The underlying cause of the error is available using the |
||||
`Cause` function. |
||||
|
||||
os.IsNotExist(errors.Cause(err)) |
||||
|
||||
The result of the `Error()` call on an annotated error is the annotations joined |
||||
with colons, then the result of the `Error()` method for the underlying error |
||||
that was the cause. |
||||
|
||||
err := errors.Errorf("original") |
||||
err = errors.Annotatef(err, "context") |
||||
err = errors.Annotatef(err, "more context") |
||||
err.Error() -> "more context: context: original" |
||||
|
||||
Obviously recording the file, line and functions is not very useful if you |
||||
cannot get them back out again. |
||||
|
||||
errors.ErrorStack(err) |
||||
|
||||
will return something like: |
||||
|
||||
first error |
||||
github.com/juju/errors/annotation_test.go:193: |
||||
github.com/juju/errors/annotation_test.go:194: annotation |
||||
github.com/juju/errors/annotation_test.go:195: |
||||
github.com/juju/errors/annotation_test.go:196: more context |
||||
github.com/juju/errors/annotation_test.go:197: |
||||
|
||||
The first error was generated by an external system, so there was no location |
||||
associated. The second, fourth, and last lines were generated with Trace calls, |
||||
and the other two through Annotate. |
||||
|
||||
Sometimes when responding to an error you want to return a more specific error |
||||
for the situation. |
||||
|
||||
if err := FindField(field); err != nil { |
||||
return errors.Wrap(err, errors.NotFoundf(field)) |
||||
} |
||||
|
||||
This returns an error where the complete error stack is still available, and |
||||
`errors.Cause()` will return the `NotFound` error. |

GNU LESSER GENERAL PUBLIC LICENSE |
||||
Version 3, 29 June 2007 |
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
||||
Everyone is permitted to copy and distribute verbatim copies |
||||
of this license document, but changing it is not allowed. |
||||
|
||||
|
||||
This version of the GNU Lesser General Public License incorporates |
||||
the terms and conditions of version 3 of the GNU General Public |
||||
License, supplemented by the additional permissions listed below. |
||||
|
||||
0. Additional Definitions. |
||||
|
||||
As used herein, "this License" refers to version 3 of the GNU Lesser |
||||
General Public License, and the "GNU GPL" refers to version 3 of the GNU |
||||
General Public License. |
||||
|
||||
"The Library" refers to a covered work governed by this License, |
||||
other than an Application or a Combined Work as defined below. |
||||
|
||||
An "Application" is any work that makes use of an interface provided |
||||
by the Library, but which is not otherwise based on the Library. |
||||
Defining a subclass of a class defined by the Library is deemed a mode |
||||
of using an interface provided by the Library. |
||||
|
||||
A "Combined Work" is a work produced by combining or linking an |
||||
Application with the Library. The particular version of the Library |
||||
with which the Combined Work was made is also called the "Linked |
||||
Version". |
||||
|
||||
The "Minimal Corresponding Source" for a Combined Work means the |
||||
Corresponding Source for the Combined Work, excluding any source code |
||||
for portions of the Combined Work that, considered in isolation, are |
||||
based on the Application, and not on the Linked Version. |
||||
|
||||
The "Corresponding Application Code" for a Combined Work means the |
||||
object code and/or source code for the Application, including any data |
||||
and utility programs needed for reproducing the Combined Work from the |
||||
Application, but excluding the System Libraries of the Combined Work. |
||||
|
||||
1. Exception to Section 3 of the GNU GPL. |
||||
|
||||
You may convey a covered work under sections 3 and 4 of this License |
||||
without being bound by section 3 of the GNU GPL. |
||||
|
||||
2. Conveying Modified Versions. |
||||
|
||||
If you modify a copy of the Library, and, in your modifications, a |
||||
facility refers to a function or data to be supplied by an Application |
||||
that uses the facility (other than as an argument passed when the |
||||
facility is invoked), then you may convey a copy of the modified |
||||
version: |
||||
|
||||
a) under this License, provided that you make a good faith effort to |
||||
ensure that, in the event an Application does not supply the |
||||
function or data, the facility still operates, and performs |
||||
whatever part of its purpose remains meaningful, or |
||||
|
||||
b) under the GNU GPL, with none of the additional permissions of |
||||
this License applicable to that copy. |
||||
|
||||
3. Object Code Incorporating Material from Library Header Files. |
||||
|
||||
The object code form of an Application may incorporate material from |
||||
a header file that is part of the Library. You may convey such object |
||||
code under terms of your choice, provided that, if the incorporated |
||||
material is not limited to numerical parameters, data structure |
||||
layouts and accessors, or small macros, inline functions and templates |
||||
(ten or fewer lines in length), you do both of the following: |
||||
|
||||
a) Give prominent notice with each copy of the object code that the |
||||
Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the object code with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
4. Combined Works. |
||||
|
||||
You may convey a Combined Work under terms of your choice that, |
||||
taken together, effectively do not restrict modification of the |
||||
portions of the Library contained in the Combined Work and reverse |
||||
engineering for debugging such modifications, if you also do each of |
||||
the following: |
||||
|
||||
a) Give prominent notice with each copy of the Combined Work that |
||||
the Library is used in it and that the Library and its use are |
||||
covered by this License. |
||||
|
||||
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
||||
document. |
||||
|
||||
c) For a Combined Work that displays copyright notices during |
||||
execution, include the copyright notice for the Library among |
||||
these notices, as well as a reference directing the user to the |
||||
copies of the GNU GPL and this license document. |
||||
|
||||
d) Do one of the following: |
||||
|
||||
0) Convey the Minimal Corresponding Source under the terms of this |
||||
License, and the Corresponding Application Code in a form |
||||
suitable for, and under terms that permit, the user to |
||||
recombine or relink the Application with a modified version of |
||||
the Linked Version to produce a modified Combined Work, in the |
||||
manner specified by section 6 of the GNU GPL for conveying |
||||
Corresponding Source. |
||||
|
||||
1) Use a suitable shared library mechanism for linking with the |
||||
Library. A suitable mechanism is one that (a) uses at run time |
||||
a copy of the Library already present on the user's computer |
||||
system, and (b) will operate properly with a modified version |
||||
of the Library that is interface-compatible with the Linked |
||||
Version. |
||||
|
||||
e) Provide Installation Information, but only if you would otherwise |
||||
be required to provide such information under section 6 of the |
||||
GNU GPL, and only to the extent that such information is |
||||
necessary to install and execute a modified version of the |
||||
Combined Work produced by recombining or relinking the |
||||
Application with a modified version of the Linked Version. (If |
||||
you use option 4d0, the Installation Information must accompany |
||||
the Minimal Corresponding Source and Corresponding Application |
||||
Code. If you use option 4d1, you must provide the Installation |
||||
Information in the manner specified by section 6 of the GNU GPL |
||||
for conveying Corresponding Source.) |
||||
|
||||
5. Combined Libraries. |
||||
|
||||
You may place library facilities that are a work based on the |
||||
Library side by side in a single library together with other library |
||||
facilities that are not Applications and are not covered by this |
||||
License, and convey such a combined library under terms of your |
||||
choice, if you do both of the following: |
||||
|
||||
a) Accompany the combined library with a copy of the same work based |
||||
on the Library, uncombined with any other library facilities, |
||||
conveyed under the terms of this License. |
||||
|
||||
b) Give prominent notice with the combined library that part of it |
||||
is a work based on the Library, and explaining where to find the |
||||
accompanying uncombined form of the same work. |
||||
|
||||
6. Revised Versions of the GNU Lesser General Public License. |
||||
|
||||
The Free Software Foundation may publish revised and/or new versions |
||||
of the GNU Lesser General Public License from time to time. Such new |
||||
versions will be similar in spirit to the present version, but may |
||||
differ in detail to address new problems or concerns. |
||||
|
||||
Each version is given a distinguishing version number. If the |
||||
Library as you received it specifies that a certain numbered version |
||||
of the GNU Lesser General Public License "or any later version" |
||||
applies to it, you have the option of following the terms and |
||||
conditions either of that published version or of any later version |
||||
published by the Free Software Foundation. If the Library as you |
||||
received it does not specify a version number of the GNU Lesser |
||||
General Public License, you may choose any version of the GNU Lesser |
||||
General Public License ever published by the Free Software Foundation. |
||||
|
||||
If the Library as you received it specifies that a proxy can decide |
||||
whether future versions of the GNU Lesser General Public License shall |
||||
apply, that proxy's public statement of acceptance of any version is |
||||
permanent authorization for you to choose that version for the |
||||
Library. |

(an example is provided in the Appendix below). |
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object |
||||
form, that is based on (or derived from) the Work and for which the |
||||
editorial revisions, annotations, elaborations, or other modifications |
||||
represent, as a whole, an original work of authorship. For the purposes |
||||
of this License, Derivative Works shall not include works that remain |

2. Grant of Copyright License. Subject to the terms and conditions of |
||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
copyright license to reproduce, prepare Derivative Works of, |

||||
by such Contributor that are necessarily infringed by their |
||||
Contribution(s) alone or by combination of their Contribution(s) |
||||
with the Work to which such Contribution(s) was submitted. If You |
||||
institute patent litigation against any entity (including a |
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work |
||||
or a Contribution incorporated within the Work constitutes direct |
||||
or contributory patent infringement, then any patent licenses |
||||
granted to You under this License for that Work shall terminate |
||||
as of the date such litigation is filed. |
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the |
||||
Work or Derivative Works thereof in any medium, with or without |
||||
modifications, and in Source or Object form, provided that You |
||||
meet the following conditions: |
||||
|
||||
(a) You must give any other recipients of the Work or |
||||
Derivative Works a copy of this License; and |
||||
|
||||
(b) You must cause any modified files to carry prominent notices |
||||
stating that You changed the files; and |
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works |
||||
that You distribute, all copyright, patent, trademark, and |
||||
attribution notices from the Source form of the Work, |
||||
excluding those notices that do not pertain to any part of |
||||
the Derivative Works; and |
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its |
||||
distribution, then any Derivative Works that You distribute must |
||||
include a readable copy of the attribution notices contained |
||||
within such NOTICE file, excluding those notices that do not |
||||
pertain to any part of the Derivative Works, in at least one |
||||
of the following places: within a NOTICE text file distributed |
||||
as part of the Derivative Works; within the Source form or |
||||
documentation, if provided along with the Derivative Works; or, |
||||
within a display generated by the Derivative Works, if and |
||||
wherever such third-party notices normally appear. The contents |
||||
of the NOTICE file are for informational purposes only and |
||||
do not modify the License. You may add Your own attribution |
||||
notices within Derivative Works that You distribute, alongside |
||||
or as an addendum to the NOTICE text from the Work, provided |
||||
that such additional attribution notices cannot be construed |
||||
as modifying the License. |
||||
|
||||
You may add Your own copyright statement to Your modifications and |
||||
may provide additional or different license terms and conditions |
||||
for use, reproduction, or distribution of Your modifications, or |
||||
for any such Derivative Works as a whole, provided Your use, |
||||
reproduction, and distribution of the Work otherwise complies with |
||||
the conditions stated in this License. |
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise, |
||||
any Contribution intentionally submitted for inclusion in the Work |
||||
by You to the Licensor shall be under the terms and conditions of |
||||
this License, without any additional terms or conditions. |
||||
Notwithstanding the above, nothing herein shall supersede or modify |
||||
the terms of any separate license agreement you may have executed |
||||
with Licensor regarding such Contributions. |
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade |
||||
names, trademarks, service marks, or product names of the Licensor, |
||||
except as required for reasonable and customary use in describing the |
||||
origin of the Work and reproducing the content of the NOTICE file. |
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or |
||||
agreed to in writing, Licensor provides the Work (and each |
||||
Contributor provides its Contributions) on an "AS IS" BASIS, |
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
||||
implied, including, without limitation, any warranties or conditions |
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |
||||
PARTICULAR PURPOSE. You are solely responsible for determining the |
||||
appropriateness of using or redistributing the Work and assume any |
||||
risks associated with Your exercise of permissions under this License. |
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory, |
||||
whether in tort (including negligence), contract, or otherwise, |
||||
unless required by applicable law (such as deliberate and grossly |
||||
negligent acts) or agreed to in writing, shall any Contributor be |
||||
liable to You for damages, including any direct, indirect, special, |
||||
incidental, or consequential damages of any character arising as a |
||||
result of this License or out of the use or inability to use the |
||||
Work (including but not limited to damages for loss of goodwill, |
||||
work stoppage, computer failure or malfunction, or any and all |
||||
other commercial damages or losses), even if such Contributor |
||||
has been advised of the possibility of such damages. |
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing |
||||
the Work or Derivative Works thereof, You may choose to offer, |
||||
and charge a fee for, acceptance of support, warranty, indemnity, |
||||
or other liability obligations and/or rights consistent with this |
||||
License. However, in accepting such obligations, You may act only |
||||
on Your own behalf and on Your sole responsibility, not on behalf |
||||
of any other Contributor, and only if You agree to indemnify, |
||||
defend, and hold each Contributor harmless for any liability |
||||
incurred by, or claims asserted against, such Contributor by reason |
||||
of your accepting any such warranty or additional liability. |
