"You" (or "Your") shall mean an individual or Legal Entity | |||||
exercising permissions granted by this License. | |||||
"Source" form shall mean the preferred form for making modifications, | |||||
including but not limited to software source code, documentation | |||||
source, and configuration files. | |||||

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 | |||||
separable from, or merely link (or bind by name) to the interfaces of, | |||||
the Work and Derivative Works thereof. | |||||
"Contribution" shall mean any work of authorship, including | |||||

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, | |||||

use, offer to sell, sell, import, and otherwise transfer the Work, | |||||
where such license applies only to those patent claims licensable | |||||
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 | |||||

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 | |||||

6. Trademarks. This License does not grant permission to use the trade | |||||
names, trademarks, service marks, or product names of the Licensor, | |||||

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. | |||||

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 | |||||

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. |

[godoc-link-here] | |||||
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. |
