2. License Grants and Conditions

|
||||||
|
|
||||||
2.1. Grants
|
|
||||||
|
|
||||||
Each Contributor hereby grants You a world-wide, royalty-free,
|
|
||||||
non-exclusive license:
|
|
||||||
|
|
||||||
a. under intellectual property rights (other than patent or trademark)
|
|
||||||
Licensable by such Contributor to use, reproduce, make available,
|
|
||||||
modify, display, perform, distribute, and otherwise exploit its
|
|

|
|
||||||

|
|

|
||||||
or its Contributor Version.
|
|
||||||
|
|
||||||
2.2. Effective Date
|
|
||||||
|
|
||||||
The licenses granted in Section 2.1 with respect to any Contribution become
|
|
||||||
effective for each Contribution on the date the Contributor first distributes
|
|
||||||
such Contribution.
|
|
||||||
|
|
||||||
2.3. Limitations on Grant Scope
|
|
||||||
|
|
||||||
The licenses granted in this Section 2 are the only rights granted under this
|
|
||||||
License. No additional rights or licenses will be implied from the distribution
|
|
||||||
or licensing of Covered Software under this License. Notwithstanding Section
|
|
||||||
2.1(b) above, no patent license is granted by a Contributor:
|
|
||||||
|
|
||||||
a. for any code that a Contributor has removed from Covered Software; or
|
|
||||||
|
|
||||||
b. for infringements caused by: (i) Your and any other third party’s
|
|
||||||
modifications of Covered Software, or (ii) the combination of its
|
|
||||||
Contributions with other software (except as part of its Contributor
|
|
||||||
Version); or
|
|
||||||
|
|
||||||
c. under Patent Claims infringed by Covered Software in the absence of its
|
|
||||||
Contributions.
|
|
||||||
|
|
||||||
This License does not grant any rights in the trademarks, service marks, or
|
|
||||||
logos of any Contributor (except as may be necessary to comply with the
|
|
||||||
notice requirements in Section 3.4).
|
|
||||||
|
|
||||||
2.4. Subsequent Licenses
|
|
||||||
|
|
||||||
No Contributor makes additional grants as a result of Your choice to
|
|
||||||
distribute the Covered Software under a subsequent version of this License
|
|
||||||
(see Section 10.2) or under the terms of a Secondary License (if permitted
|
|
||||||
under the terms of Section 3.3).
|
|
||||||
|
|
||||||
2.5. Representation
|
|
||||||
|
|
||||||
Each Contributor represents that the Contributor believes its Contributions
|
|
||||||
are its original creation(s) or it has sufficient rights to grant the
|
|
||||||
rights to its Contributions conveyed by this License.
|
|
||||||
|
|
||||||
2.6. Fair Use
|
|
||||||
|
|
||||||
This License is not intended to limit any rights You have under applicable
|
|
||||||
copyright doctrines of fair use, fair dealing, or other equivalents.
|
|
||||||
|
|
||||||
2.7. Conditions
|
|
||||||
|
|
||||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
|
|
||||||
Section 2.1.
|
|
||||||
|
|
||||||
|
|
||||||
3. Responsibilities
|
|
||||||
|
|
||||||
3.1. Distribution of Source Form
|
|
||||||
|
|
||||||
All distribution of Covered Software in Source Code Form, including any
|
|
||||||
Modifications that You create or to which You contribute, must be under the
|
|
||||||
terms of this License. You must inform recipients that the Source Code Form
|
|
||||||
of the Covered Software is governed by the terms of this License, and how
|
|
||||||
they can obtain a copy of this License. You may not attempt to alter or
|
|
||||||
restrict the recipients’ rights in the Source Code Form.
|
|
||||||
|
|
||||||
3.2. Distribution of Executable Form
|
|
||||||
|
|
||||||
If You distribute Covered Software in Executable Form then:
|
|
||||||
|
|
||||||
a. such Covered Software must also be made available in Source Code Form,
|
|
||||||
as described in Section 3.1, and You must inform recipients of the
|
|
||||||
Executable Form how they can obtain a copy of such Source Code Form by
|
|
||||||
reasonable means in a timely manner, at a charge no more than the cost
|
|
||||||
of distribution to the recipient; and
|
|
||||||
|
|
||||||
b. You may distribute such Executable Form under the terms of this License,
|
|
||||||
or sublicense it under different terms, provided that the license for
|
|
||||||
the Executable Form does not attempt to limit or alter the recipients’
|
|
||||||
rights in the Source Code Form under this License.
|
|
||||||
|
|
||||||
3.3. Distribution of a Larger Work
|
|
||||||
|
|
||||||
You may create and distribute a Larger Work under terms of Your choice,
|
|
||||||
provided that You also comply with the requirements of this License for the
|
|
||||||
Covered Software. If the Larger Work is a combination of Covered Software
|
|
||||||
with a work governed by one or more Secondary Licenses, and the Covered
|
|
||||||
Software is not Incompatible With Secondary Licenses, this License permits
|
|
||||||
You to additionally distribute such Covered Software under the terms of
|
|
||||||
such Secondary License(s), so that the recipient of the Larger Work may, at
|
|
||||||
their option, further distribute the Covered Software under the terms of
|
|
||||||
either this License or such Secondary License(s).
|
|
||||||
|
|
||||||
3.4. Notices
|
|
||||||
|
|
||||||
You may not remove or alter the substance of any license notices (including
|
|
||||||
copyright notices, patent notices, disclaimers of warranty, or limitations
|
|
||||||
of liability) contained within the Source Code Form of the Covered
|
|
||||||
Software, except that You may alter any license notices to the extent
|
|
||||||
required to remedy known factual inaccuracies.
|
|
||||||
|
|
||||||
3.5. Application of Additional Terms
|
|
||||||
|
|
||||||
You may choose to offer, and to charge a fee for, warranty, support,
|
|
||||||
indemnity or liability obligations to one or more recipients of Covered
|
|
||||||
Software. However, You may do so only on Your own behalf, and not on behalf
|
|
||||||
of any Contributor. You must make it absolutely clear that any such
|
|
||||||
warranty, support, indemnity, or liability obligation is offered by You
|
|
||||||
alone, and You hereby agree to indemnify every Contributor for any
|
|
||||||
liability incurred by such Contributor as a result of warranty, support,
|
|
||||||
indemnity or liability terms You offer. You may include additional
|
|
||||||
disclaimers of warranty and limitations of liability specific to any
|
|
||||||
jurisdiction.
|
|
||||||
|
|
||||||
4. Inability to Comply Due to Statute or Regulation
|
|
||||||
|
|
||||||
If it is impossible for You to comply with any of the terms of this License
|
|
||||||
with respect to some or all of the Covered Software due to statute, judicial
|
|
||||||
order, or regulation then You must: (a) comply with the terms of this License
|
|
||||||
to the maximum extent possible; and (b) describe the limitations and the code
|
|
||||||
they affect. Such description must be placed in a text file included with all
|
|
||||||
distributions of the Covered Software under this License. Except to the
|
|
||||||
extent prohibited by statute or regulation, such description must be
|
|
||||||
sufficiently detailed for a recipient of ordinary skill to be able to
|
|
||||||
understand it.
|
|
||||||
|
|
||||||
5. Termination
|
|
||||||
|
|
||||||
5.1. The rights granted under this License will terminate automatically if You
|
|
||||||
fail to comply with any of its terms. However, if You become compliant,
|
|
||||||
then the rights granted under this License from a particular Contributor
|
|
||||||
are reinstated (a) provisionally, unless and until such Contributor
|
|
||||||
explicitly and finally terminates Your grants, and (b) on an ongoing basis,
|
|
||||||
if such Contributor fails to notify You of the non-compliance by some
|
|
||||||
reasonable means prior to 60 days after You have come back into compliance.
|
|
||||||
Moreover, Your grants from a particular Contributor are reinstated on an
|
|
||||||
ongoing basis if such Contributor notifies You of the non-compliance by
|
|
||||||
some reasonable means, this is the first time You have received notice of
|
|
||||||
non-compliance with this License from such Contributor, and You become
|
|
||||||
compliant prior to 30 days after Your receipt of the notice.
|
|
||||||
|
|
||||||
5.2. If You initiate litigation against any entity by asserting a patent
|
|
||||||
infringement claim (excluding declaratory judgment actions, counter-claims,
|
|
||||||
and cross-claims) alleging that a Contributor Version directly or
|
|
||||||
indirectly infringes any patent, then the rights granted to You by any and
|
|
||||||
all Contributors for the Covered Software under Section 2.1 of this License
|
|
||||||
shall terminate.
|
|
||||||
|

# errwrap
|
|
||||||
|
|
||||||
`errwrap` is a package for Go that formalizes the pattern of wrapping errors
|
|
||||||
and checking if an error contains another error.
|
|
||||||
|
|
||||||
There is a common pattern in Go of taking a returned `error` value and
|
|
||||||
then wrapping it (such as with `fmt.Errorf`) before returning it. The problem
|
|
||||||
with this pattern is that you completely lose the original `error` structure.
|
|
||||||
|
|
||||||
Arguably the _correct_ approach is that you should make a custom structure
|
|
||||||
implementing the `error` interface, and have the original error as a field
|
|
||||||
on that structure, such [as this example](http://golang.org/pkg/os/#PathError).
|
|
||||||
This is a good approach, but you have to know the entire chain of possible
|
|
||||||
rewrapping that happens, when you might just care about one.
|
|
||||||
|
|
||||||
`errwrap` formalizes this pattern (it doesn't matter what approach you use
|
|
||||||
above) by giving a single interface for wrapping errors, checking if a specific
|
|
||||||
error is wrapped, and extracting that error.
|
|
||||||
|
|
||||||
## Installation and Docs
|
|
||||||
|
|
||||||
Install using `go get github.com/hashicorp/errwrap`.
|
|
||||||
|
|
||||||
Full documentation is available at
|
|
||||||
http://godoc.org/github.com/hashicorp/errwrap
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
#### Basic Usage
|
|
||||||
|
|
||||||
Below is a very basic example of its usage:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// A function that always returns an error, but wraps it, like a real
|
|
||||||
// function might.
|
|
||||||
func tryOpen() error {
|
|
||||||
_, err := os.Open("/i/dont/exist")
|
|
||||||
if err != nil {
|
|
||||||
return errwrap.Wrapf("Doesn't exist: {{err}}", err)
|
|
||||||
}
|
|
||||||
|
|
||||||
return nil
|
|
||||||
}
|
|
||||||
|
|
||||||
func main() {
|
|
||||||
err := tryOpen()
|
|
||||||
|
|
||||||
// We can use the Contains helpers to check if an error contains
|
|
||||||
// another error. It is safe to do this with a nil error, or with
|
|
||||||
// an error that doesn't even use the errwrap package.
|
|
||||||
if errwrap.Contains(err, "does not exist") {
|
|
||||||
// Do something
|
|
||||||
}
|
|
||||||
if errwrap.ContainsType(err, new(os.PathError)) {
|
|
||||||
// Do something
|
|
||||||
}
|
|
||||||
|
|
||||||
// Or we can use the associated `Get` functions to just extract
|
|
||||||
// a specific error. This would return nil if that specific error doesn't
|
|
||||||
// exist.
|
|
||||||
perr := errwrap.GetType(err, new(os.PathError))
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
#### Custom Types
|
|
||||||
|
|
||||||
If you're already making custom types that properly wrap errors, then
|
|
||||||
you can get all the functionality of `errwraps.Contains` and such by
|
|
||||||
implementing the `Wrapper` interface with just one function. Example:
|
|
||||||
|
|
||||||
```go
|
|
||||||
type AppError {
|
|
||||||
Code ErrorCode
|
|
||||||
Err error
|
|
||||||
}
|
|
||||||
|
|
||||||
func (e *AppError) WrappedErrors() []error {
|
|
||||||
return []error{e.Err}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Now this works:
|
|
||||||
|
|
||||||
```go
|
|
||||||
err := &AppError{Err: fmt.Errorf("an error")}
|
|
||||||
if errwrap.ContainsType(err, fmt.Errorf("")) {
|
|
||||||
// This will work!
|
|
||||||
}
|
|
||||||
```

2. License Grants and Conditions
|
|
||||||
|
|
||||||
2.1. Grants
|
|
||||||
|
|
||||||
Each Contributor hereby grants You a world-wide, royalty-free,
|
|
||||||
non-exclusive license:
|
|
||||||
|
|
||||||
a. under intellectual property rights (other than patent or trademark)
|
|
||||||
Licensable by such Contributor to use, reproduce, make available,
|
|
||||||
modify, display, perform, distribute, and otherwise exploit its
|
|
||||||
Contributions, either on an unmodified basis, with Modifications, or as
|
|
||||||
part of a Larger Work; and
|
|
||||||
|
|
||||||
b. under Patent Claims of such Contributor to make, use, sell, offer for
|
|
||||||
sale, have made, import, and otherwise transfer either its Contributions
|
|
||||||
or its Contributor Version.
|
|
||||||
|
|
||||||
2.2. Effective Date
|
|
||||||
|
|
||||||
The licenses granted in Section 2.1 with respect to any Contribution become
|
|
||||||
effective for each Contribution on the date the Contributor first distributes
|
|
||||||
such Contribution.
|
|
||||||
|
|
||||||
2.3. Limitations on Grant Scope
|
|
||||||
|
|
||||||
The licenses granted in this Section 2 are the only rights granted under this
|
|
||||||
License. No additional rights or licenses will be implied from the distribution
|
|
||||||
or licensing of Covered Software under this License. Notwithstanding Section
|
|
||||||
2.1(b) above, no patent license is granted by a Contributor:
|
|
||||||
|
|
||||||
a. for any code that a Contributor has removed from Covered Software; or
|
|
||||||
|
|
||||||
b. for infringements caused by: (i) Your and any other third party’s
|
|
||||||
modifications of Covered Software, or (ii) the combination of its
|
|
||||||
Contributions with other software (except as part of its Contributor
|
|
||||||
Version); or
|
|
||||||
|
|
||||||
c. under Patent Claims infringed by Covered Software in the absence of its
|
|
||||||
Contributions.
|
|
||||||
|
|
||||||
This License does not grant any rights in the trademarks, service marks, or
|
|
||||||
logos of any Contributor (except as may be necessary to comply with the
|
|
||||||
notice requirements in Section 3.4).
|
|
||||||
|
|
||||||
2.4. Subsequent Licenses
|
|
||||||
|
|
||||||
No Contributor makes additional grants as a result of Your choice to
|
|
||||||
distribute the Covered Software under a subsequent version of this License
|
|
||||||
(see Section 10.2) or under the terms of a Secondary License (if permitted
|
|
||||||
under the terms of Section 3.3).
|
|
||||||
|
|
||||||
2.5. Representation
|
|
||||||
|
|
||||||
Each Contributor represents that the Contributor believes its Contributions
|
|
||||||
are its original creation(s) or it has sufficient rights to grant the
|
|
||||||
rights to its Contributions conveyed by this License.
|
|
||||||
|
|
||||||
2.6. Fair Use
|
|
||||||
|
|
||||||
This License is not intended to limit any rights You have under applicable
|
|
||||||
copyright doctrines of fair use, fair dealing, or other equivalents.
|
|
||||||
|
|
||||||
2.7. Conditions
|
|
||||||
|
|
||||||
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
|
|
||||||
Section 2.1.
|
|
||||||
|
|
||||||
|
|
||||||
3. Responsibilities
|
|
||||||
|
|
||||||
3.1. Distribution of Source Form
|
|
||||||
|
|
||||||
All distribution of Covered Software in Source Code Form, including any
|
|
||||||
Modifications that You create or to which You contribute, must be under the
|
|
||||||
terms of this License. You must inform recipients that the Source Code Form
|
|
||||||
of the Covered Software is governed by the terms of this License, and how
|
|
||||||
they can obtain a copy of this License. You may not attempt to alter or
|
|
||||||
restrict the recipients’ rights in the Source Code Form.
|
|
||||||
|
|
||||||
3.2. Distribution of Executable Form
|
|
||||||
|
|
||||||
If You distribute Covered Software in Executable Form then:
|
|
||||||
|
|
||||||
a. such Covered Software must also be made available in Source Code Form,
|
|
||||||
as described in Section 3.1, and You must inform recipients of the
|
|
||||||
Executable Form how they can obtain a copy of such Source Code Form by
|
|
||||||
reasonable means in a timely manner, at a charge no more than the cost
|
|
||||||
of distribution to the recipient; and
|
|
||||||
|
|
||||||
b. You may distribute such Executable Form under the terms of this License,
|
|
||||||
or sublicense it under different terms, provided that the license for
|
|
||||||
the Executable Form does not attempt to limit or alter the recipients’
|
|
||||||
rights in the Source Code Form under this License.
|
|
||||||
|
|
||||||
3.3. Distribution of a Larger Work
|
|
||||||
|
|
||||||
You may create and distribute a Larger Work under terms of Your choice,
|
|
||||||
provided that You also comply with the requirements of this License for the
|
|
||||||
Covered Software. If the Larger Work is a combination of Covered Software
|
|
||||||
with a work governed by one or more Secondary Licenses, and the Covered
|
|
||||||
Software is not Incompatible With Secondary Licenses, this License permits
|
|
||||||
You to additionally distribute such Covered Software under the terms of
|
|
||||||
such Secondary License(s), so that the recipient of the Larger Work may, at
|
|
||||||
their option, further distribute the Covered Software under the terms of
|
|
||||||
either this License or such Secondary License(s).
|
|
||||||
|
|
||||||
3.4. Notices
|
|
||||||
|
|
||||||
You may not remove or alter the substance of any license notices (including
|
|
||||||
copyright notices, patent notices, disclaimers of warranty, or limitations
|
|
||||||
of liability) contained within the Source Code Form of the Covered
|
|
||||||
Software, except that You may alter any license notices to the extent
|
|
||||||
required to remedy known factual inaccuracies.
|
|
||||||
|
|
||||||
3.5. Application of Additional Terms
|
|
||||||
|
|
||||||
You may choose to offer, and to charge a fee for, warranty, support,
|
|
||||||
indemnity or liability obligations to one or more recipients of Covered
|
|
||||||
Software. However, You may do so only on Your own behalf, and not on behalf
|
|
||||||
of any Contributor. You must make it absolutely clear that any such
|
|
||||||
warranty, support, indemnity, or liability obligation is offered by You
|
|
||||||
alone, and You hereby agree to indemnify every Contributor for any
|
|
||||||
liability incurred by such Contributor as a result of warranty, support,
|
|
||||||
indemnity or liability terms You offer. You may include additional
|
|
||||||
disclaimers of warranty and limitations of liability specific to any
|
|
||||||
jurisdiction.
|
|
||||||
|
|
||||||
4. Inability to Comply Due to Statute or Regulation
|
|
||||||
|
|
||||||
If it is impossible for You to comply with any of the terms of this License
|
|
||||||
with respect to some or all of the Covered Software due to statute, judicial
|
|
||||||
order, or regulation then You must: (a) comply with the terms of this License
|
|
||||||
to the maximum extent possible; and (b) describe the limitations and the code
|
|
||||||
they affect. Such description must be placed in a text file included with all
|
|
||||||
distributions of the Covered Software under this License. Except to the
|
|
||||||
extent prohibited by statute or regulation, such description must be
|
|
||||||
sufficiently detailed for a recipient of ordinary skill to be able to
|
|
||||||
understand it.
|
|
||||||
|
|
||||||
5. Termination
|
|
||||||
|
|
||||||
5.1. The rights granted under this License will terminate automatically if You
|
|
||||||
fail to comply with any of its terms. However, if You become compliant,
|
|
||||||
then the rights granted under this License from a particular Contributor
|
|
||||||
are reinstated (a) provisionally, unless and until such Contributor
|
|
||||||
explicitly and finally terminates Your grants, and (b) on an ongoing basis,
|
|
||||||
if such Contributor fails to notify You of the non-compliance by some
|
|
||||||
reasonable means prior to 60 days after You have come back into compliance.
|
|
||||||
Moreover, Your grants from a particular Contributor are reinstated on an
|
|
||||||
ongoing basis if such Contributor notifies You of the non-compliance by
|
|
||||||
some reasonable means, this is the first time You have received notice of
|
|
||||||
non-compliance with this License from such Contributor, and You become
|
|
||||||
compliant prior to 30 days after Your receipt of the notice.
|
|
||||||
|
|
||||||
5.2. If You initiate litigation against any entity by asserting a patent
|
|
||||||
infringement claim (excluding declaratory judgment actions, counter-claims,
|
|
||||||
and cross-claims) alleging that a Contributor Version directly or
|
|
||||||
indirectly infringes any patent, then the rights granted to You by any and
|
|
||||||
all Contributors for the Covered Software under Section 2.1 of this License
|
|
||||||
shall terminate.
|
|
||||||
|
|
||||||
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
|
|
||||||
license agreements (excluding distributors and resellers) which have been
|
|
||||||
validly granted by You or Your distributors under this License prior to
|
|
||||||
termination shall survive termination.
|
|
||||||
|
|
||||||
6. Disclaimer of Warranty
|
|
||||||
|
|
||||||
Covered Software is provided under this License on an “as is” basis, without
|
|
||||||
warranty of any kind, either expressed, implied, or statutory, including,
|
|
||||||
without limitation, warranties that the Covered Software is free of defects,
|
|
||||||
merchantable, fit for a particular purpose or non-infringing. The entire
|
|
||||||
risk as to the quality and performance of the Covered Software is with You.
|
|
||||||
Should any Covered Software prove defective in any respect, You (not any
|
|
||||||
Contributor) assume the cost of any necessary servicing, repair, or
|
|
||||||
correction. This disclaimer of warranty constitutes an essential part of this
|
|
||||||
License. No use of any Covered Software is authorized under this License
|
|
||||||
except under this disclaimer.
|
|
||||||
|
|
||||||
7. Limitation of Liability
|
|
||||||
|
|
||||||
Under no circumstances and under no legal theory, whether tort (including
|
|
||||||
negligence), contract, or otherwise, shall any Contributor, or anyone who
|
|
||||||
distributes Covered Software as permitted above, be liable to You for any
|
|
||||||
direct, indirect, special, incidental, or consequential damages of any
|
|
||||||
character including, without limitation, damages for lost profits, loss of
|
|
||||||
goodwill, work stoppage, computer failure or malfunction, or any and all
|
|
||||||
other commercial damages or losses, even if such party shall have been
|
|
||||||
informed of the possibility of such damages. This limitation of liability
|
|
||||||
shall not apply to liability for death or personal injury resulting from such
|
|
||||||
party’s negligence to the extent applicable law prohibits such limitation.
|
|
||||||
Some jurisdictions do not allow the exclusion or limitation of incidental or
|
|
||||||
consequential damages, so this exclusion and limitation may not apply to You.
|
|
||||||
|
|
||||||
8. Litigation
|
|
||||||
|
|
||||||
Any litigation relating to this License may be brought only in the courts of
|
|
||||||
a jurisdiction where the defendant maintains its principal place of business
|
|
||||||
and such litigation shall be governed by laws of that jurisdiction, without
|
|
||||||
reference to its conflict-of-law provisions. Nothing in this Section shall
|
|
||||||
prevent a party’s ability to bring cross-claims or counter-claims.
|
|
||||||
|
|
||||||
9. Miscellaneous
|
|
||||||
|
|
||||||
This License represents the complete agreement concerning the subject matter
|
|
||||||
hereof. If any provision of this License is held to be unenforceable, such
|
|
||||||
provision shall be reformed only to the extent necessary to make it
|
|
||||||
enforceable. Any law or regulation which provides that the language of a
|
|
||||||
contract shall be construed against the drafter shall not be used to construe
|
|
||||||
this License against a Contributor.
|
|
||||||
|
|
||||||
|
|
||||||
10. Versions of the License
|
|
||||||
|
|
||||||
10.1. New Versions
|
|
||||||
|
|
||||||
Mozilla Foundation is the license steward. Except as provided in Section
|
|
||||||
10.3, no one other than the license steward has the right to modify or
|
|
||||||
publish new versions of this License. Each version will be given a
|
|
||||||
distinguishing version number.
|
|
||||||
|
|
||||||
10.2. Effect of New Versions
|
|
||||||
|
|
||||||
You may distribute the Covered Software under the terms of the version of
|
|
||||||
the License under which You originally received the Covered Software, or
|
|
||||||
under the terms of any subsequent version published by the license
|
|
||||||
steward.
|
|
||||||
|
|
||||||
10.3. Modified Versions
|
|
||||||
|
|
||||||
If you create software not governed by this License, and you want to
|
|
||||||
create a new license for such software, you may create and use a modified
|
|
||||||
version of this License if you rename the license and remove any
|
|
||||||
references to the name of the license steward (except to note that such
|
|
||||||
modified license differs from this License).
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
`go-multierror` is a package for Go that provides a mechanism for
|
|
||||||
representing a list of `error` values as a single `error`.
|
|
||||||
|
|
||||||
This allows a function in Go to return an `error` that might actually
|
|
||||||
be a list of errors. If the caller knows this, they can unwrap the
|
|
||||||
list and access the errors. If the caller doesn't know, the error
|
|
||||||
formats to a nice human-readable format.
|
|
||||||
|
|
||||||
`go-multierror` is fully compatible with the Go standard library
|
|
||||||
[errors](https://golang.org/pkg/errors/) package, including the
|
|
||||||
functions `As`, `Is`, and `Unwrap`. This provides a standardized approach
|
|
||||||
for introspecting on error values.
|
|
||||||
|
|
||||||
## Installation and Docs
|
|
||||||
|
|
||||||
Install using `go get github.com/hashicorp/go-multierror`.
|
|
||||||
|
|
||||||
Full documentation is available at
|
|
||||||
https://pkg.go.dev/github.com/hashicorp/go-multierror
|
|
||||||
|
|
||||||
### Requires go version 1.13 or newer
|
|
||||||
|
|
||||||
`go-multierror` requires go version 1.13 or newer. Go 1.13 introduced
|
|
||||||
[error wrapping](https://golang.org/doc/go1.13#error_wrapping), which
|
|
||||||
this library takes advantage of.
|
|
||||||
|
|
||||||
If you need to use an earlier version of go, you can use the
|
|
||||||
[v1.0.0](https://github.com/hashicorp/go-multierror/tree/v1.0.0)
|
|
||||||
tag, which doesn't rely on features in go 1.13.
|
|
||||||
|
|
||||||
If you see compile errors that look like the below, it's likely that
|
|
||||||
you're on an older version of go:
|
|
||||||
|
|
||||||
```
|
|
||||||
/go/src/github.com/hashicorp/go-multierror/multierror.go:112:9: undefined: errors.As
|
|
||||||
/go/src/github.com/hashicorp/go-multierror/multierror.go:117:9: undefined: errors.Is
|
|
||||||
```
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
go-multierror is easy to use and purposely built to be unobtrusive in
|
|
||||||
existing Go applications/libraries that may not be aware of it.
|
|
||||||
|
|
||||||
**Building a list of errors**
|
|
||||||
|
|
||||||
The `Append` function is used to create a list of errors. This function
|
|
||||||
behaves a lot like the Go built-in `append` function: it doesn't matter
|
|
||||||
if the first argument is nil, a `multierror.Error`, or any other `error`,
|
|
||||||
the function behaves as you would expect.
|
|
||||||
|
|
||||||
```go
|
|
||||||
var result error
|
|
||||||
|
|
||||||
if err := step1(); err != nil {
|
|
||||||
result = multierror.Append(result, err)
|
|
||||||
}
|
|
||||||
if err := step2(); err != nil {
|
|
||||||
result = multierror.Append(result, err)
|
|
||||||
}
|
|
||||||
|
|
||||||
return result
|
|
||||||
```
|
|
||||||
|
|
||||||
**Customizing the formatting of the errors**
|
|
||||||
|
|
||||||
By specifying a custom `ErrorFormat`, you can customize the format
|
|
||||||
of the `Error() string` function:
|
|
||||||
|
|
||||||
```go
|
|
||||||
var result *multierror.Error
|
|
||||||
|
|
||||||
// ... accumulate errors here, maybe using Append
|
|
||||||
|
|
||||||
if result != nil {
|
|
||||||
result.ErrorFormat = func([]error) string {
|
|
||||||
return "errors!"
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
**Accessing the list of errors**
|
|
||||||
|
|
||||||
`multierror.Error` implements `error` so if the caller doesn't know about
|
|
||||||
multierror, it will work just fine. But if you're aware a multierror might
|
|
||||||
be returned, you can use type switches to access the list of errors:
|
|
||||||
|
|
||||||
```go
|
|
||||||
if err := something(); err != nil {
|
|
||||||
if merr, ok := err.(*multierror.Error); ok {
|
|
||||||
// Use merr.Errors
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
You can also use the standard [`errors.Unwrap`](https://golang.org/pkg/errors/#Unwrap)
|
|
||||||
function. This will continue to unwrap into subsequent errors until none exist.
|
|
||||||
|
|
||||||
**Extracting an error**
|
|
||||||
|
|
||||||
The standard library [`errors.As`](https://golang.org/pkg/errors/#As)
|
|
||||||
function can be used directly with a multierror to extract a specific error:
|
|
||||||
|
|
||||||
```go
|
|
||||||
// Assume err is a multierror value
|
|
||||||
err := somefunc()
|
|
||||||
|
|
||||||
// We want to know if "err" has a "RichErrorType" in it and extract it.
|
|
||||||
var errRich RichErrorType
|
|
||||||
if errors.As(err, &errRich) {
|
|
||||||
// It has it, and now errRich is populated.
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
**Checking for an exact error value**
|
|
||||||
|
|
||||||
Some errors are returned as exact errors such as the [`ErrNotExist`](https://golang.org/pkg/os/#pkg-variables)
|
|
||||||
error in the `os` package. You can check if this error is present by using
|
|
||||||
the standard [`errors.Is`](https://golang.org/pkg/errors/#Is) function.
|
|
||||||
|
|
||||||
```go
|
|
||||||
// Assume err is a multierror value
|
|
||||||
err := somefunc()
|
|
||||||
if errors.Is(err, os.ErrNotExist) {
|
|
||||||
// err contains os.ErrNotExist
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
**Returning a multierror only if there are errors**
|
|
||||||
|
|
||||||
If you build a `multierror.Error`, you can use the `ErrorOrNil` function
|
|
||||||
to return an `error` implementation only if there are errors to return:
|
|
||||||
|
|
||||||
```go
|
|
||||||
var result *multierror.Error
|
|
||||||
|
|
||||||
// ... accumulate errors here
|
|
||||||
|
|
||||||
// Return the `error` only if errors were added to the multierror, otherwise
|
|
||||||
// return nil since there are no errors.
|
|
||||||
return result.ErrorOrNil()
|
|
||||||
```
