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

(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

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

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

Using Creative Commons Public Licenses
Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.
Considerations for licensors: Our public licenses are
intended for use by those authorized to give the public
permission to use material in ways otherwise restricted by
copyright and certain other rights. Our licenses are
irrevocable. Licensors should read and understand the terms
and conditions of the license they choose before applying it.
Licensors should also secure all rights necessary before
applying our licenses so that the public can reuse the
material as expected. Licensors should clearly mark any
material not subject to the license. This includes other CC-
licensed material, or material used under an exception or
limitation to copyright. More considerations for licensors:
wiki.creativecommons.org/Considerations_for_licensors
Considerations for the public: By using one of our public
licenses, a licensor grants the public permission to use the
licensed material under specified terms and conditions. If
the licensor's permission is not necessary for any reason--for
example, because of any applicable exception or limitation to
copyright--then that use is not regulated by the license. Our
licenses grant only permissions under copyright and certain
other rights that a licensor has authority to grant. Use of
the licensed material may still be restricted for other
reasons, including because others have copyright or other
rights in the material. A licensor may make special requests,
such as asking that all changes be marked or described.
Although not required by our licenses, you are encouraged to
respect those requests where reasonable. More_considerations

Creative Commons Attribution-ShareAlike 4.0 International Public
License
By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-ShareAlike 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your
acceptance of these terms and conditions, and the Licensor grants You
such rights in consideration of benefits the Licensor receives from
making the Licensed Material available under these terms and
conditions.
Section 1 -- Definitions.
a. Adapted Material means material subject to Copyright and Similar
Rights that is derived from or based upon the Licensed Material
and in which the Licensed Material is translated, altered,
arranged, transformed, or otherwise modified in a manner requiring
permission under the Copyright and Similar Rights held by the
Licensor. For purposes of this Public License, where the Licensed
Material is a musical work, performance, or sound recording,
Adapted Material is always produced where the Licensed Material is
synched in timed relation with a moving image.
b. Adapter's License means the license You apply to Your Copyright
and Similar Rights in Your contributions to Adapted Material in
accordance with the terms and conditions of this Public License.
c. BY-SA Compatible License means a license listed at
creativecommons.org/compatiblelicenses, approved by Creative
Commons as essentially the equivalent of this Public License.
d. Copyright and Similar Rights means copyright and/or similar rights
closely related to copyright including, without limitation,
performance, broadcast, sound recording, and Sui Generis Database
Rights, without regard to how the rights are labeled or
categorized. For purposes of this Public License, the rights
specified in Section 2(b)(1)-(2) are not Copyright and Similar
Rights.
e. Effective Technological Measures means those measures that, in the
absence of proper authority, may not be circumvented under laws
fulfilling obligations under Article 11 of the WIPO Copyright
Treaty adopted on December 20, 1996, and/or similar international
agreements.
f. Exceptions and Limitations means fair use, fair dealing, and/or
any other exception or limitation to Copyright and Similar Rights
that applies to Your use of the Licensed Material.
g. License Elements means the license attributes listed in the name
of a Creative Commons Public License. The License Elements of this
Public License are Attribution and ShareAlike.
h. Licensed Material means the artistic or literary work, database,
or other material to which the Licensor applied this Public
License.
i. Licensed Rights means the rights granted to You subject to the
terms and conditions of this Public License, which are limited to
all Copyright and Similar Rights that apply to Your use of the
Licensed Material and that the Licensor has authority to license.
j. Licensor means the individual(s) or entity(ies) granting rights
under this Public License.
k. Share means to provide material to the public by any means or
process that requires permission under the Licensed Rights, such
as reproduction, public display, public performance, distribution,
dissemination, communication, or importation, and to make material
available to the public including in ways that members of the
public may access the material from a place and at a time
individually chosen by them.
l. Sui Generis Database Rights means rights other than copyright
resulting from Directive 96/9/EC of the European Parliament and of
the Council of 11 March 1996 on the legal protection of databases,
as amended and/or succeeded, as well as other essentially
equivalent rights anywhere in the world.
m. You means the individual or entity exercising the Licensed Rights
under this Public License. Your has a corresponding meaning.
Section 2 -- Scope.
a. License grant.
1. Subject to the terms and conditions of this Public License,
the Licensor hereby grants You a worldwide, royalty-free,
non-sublicensable, non-exclusive, irrevocable license to
exercise the Licensed Rights in the Licensed Material to:
a. reproduce and Share the Licensed Material, in whole or
in part; and
b. produce, reproduce, and Share Adapted Material.
2. Exceptions and Limitations. For the avoidance of doubt, where
Exceptions and Limitations apply to Your use, this Public
License does not apply, and You do not need to comply with
its terms and conditions.
3. Term. The term of this Public License is specified in Section
6(a).
4. Media and formats; technical modifications allowed. The
Licensor authorizes You to exercise the Licensed Rights in
all media and formats whether now known or hereafter created,
and to make technical modifications necessary to do so. The
Licensor waives and/or agrees not to assert any right or
authority to forbid You from making technical modifications
necessary to exercise the Licensed Rights, including
technical modifications necessary to circumvent Effective
Technological Measures. For purposes of this Public License,
simply making modifications authorized by this Section 2(a)
(4) never produces Adapted Material.
5. Downstream recipients.
a. Offer from the Licensor -- Licensed Material. Every
recipient of the Licensed Material automatically
receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this
Public License.
b. Additional offer from the Licensor -- Adapted Material.
Every recipient of Adapted Material from You
automatically receives an offer from the Licensor to
exercise the Licensed Rights in the Adapted Material
under the conditions of the Adapter's License You apply.
c. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.
6. No endorsement. Nothing in this Public License constitutes or
may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,
the Licensor or others designated to receive attribution as
provided in Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not
licensed under this Public License, nor are publicity,
privacy, and/or other similar personality rights; however, to
the extent possible, the Licensor waives and/or agrees not to
assert any such rights held by the Licensor to the limited
extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
Public License.
3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties.
Section 3 -- License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.
a. Attribution.
1. If You Share the Licensed Material (including in modified
form), You must:
a. retain the following if it is supplied by the Licensor
with the Licensed Material:
i. identification of the creator(s) of the Licensed
Material and any others designated to receive
attribution, in any reasonable manner requested by
the Licensor (including by pseudonym if
designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of
warranties;
v. a URI or hyperlink to the Licensed Material to the
extent reasonably practicable;
b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and
c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.
2. You may satisfy the conditions in Section 3(a)(1) in any
reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.
3. If requested by the Licensor, You must remove any of the
information required by Section 3(a)(1)(A) to the extent
reasonably practicable.
b. ShareAlike.
In addition to the conditions in Section 3(a), if You Share
Adapted Material You produce, the following conditions also apply.
1. The Adapter's License You apply must be a Creative Commons
license with the same License Elements, this version or
later, or a BY-SA Compatible License.
2. You must include the text of, or the URI or hyperlink to, the
Adapter's License You apply. You may satisfy this condition
in any reasonable manner based on the medium, means, and
context in which You Share Adapted Material.
3. You may not offer or impose any additional or different terms
or conditions on, or apply any Effective Technological
Measures to, Adapted Material that restrict exercise of the
rights granted under the Adapter's License You apply.
Section 4 -- Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material,
including for purposes of Section 3(b); and
c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.
Section 5 -- Disclaimer of Warranties and Limitation of Liability.
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.
d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
License.
Section 7 -- Other Terms and Conditions.
a. The Licensor shall not be bound by any additional or different
terms or conditions communicated by You unless expressly agreed.
b. Any arrangements, understandings, or agreements regarding the
Licensed Material not stated herein are separate from and
independent of the terms and conditions of this Public License.
Section 8 -- Interpretation.
a. For the avoidance of doubt, this Public License does not, and
shall not be interpreted to, reduce, limit, restrict, or impose
conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the
Licensor.
d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.

# SpdyStream
A multiplexed stream library using spdy
## Usage
Client example (connecting to mirroring server without auth)
```go
package main
import (
"fmt"
"github.com/docker/spdystream"
"net"
"net/http"
)
func main() {
conn, err := net.Dial("tcp", "localhost:8080")
if err != nil {
panic(err)
}
spdyConn, err := spdystream.NewConnection(conn, false)
if err != nil {
panic(err)
}
go spdyConn.Serve(spdystream.NoOpStreamHandler)
stream, err := spdyConn.CreateStream(http.Header{}, nil, false)
if err != nil {
panic(err)
}
stream.Wait()
fmt.Fprint(stream, "Writing to stream")
buf := make([]byte, 25)
stream.Read(buf)
fmt.Println(string(buf))
stream.Close()
}
```
Server example (mirroring server without auth)
```go
package main
import (
"github.com/docker/spdystream"
"net"
)
func main() {
listener, err := net.Listen("tcp", "localhost:8080")
if err != nil {
panic(err)
}
for {
conn, err := listener.Accept()
if err != nil {
panic(err)
}
spdyConn, err := spdystream.NewConnection(conn, true)
if err != nil {
panic(err)
}
go spdyConn.Serve(spdystream.MirrorStreamHandler)
}
}
```

# YAML marshaling and unmarshaling support for Go
[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](https://travis-ci.org/ghodss/yaml)
## Introduction
A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
## Compatibility
This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
## Caveats
**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
```
BAD:
exampleKey: !!binary gIGC
GOOD:
exampleKey: gIGC
... and decode the base64 data in your code.
```
**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
## Installation and usage
To install, run:
```
$ go get github.com/ghodss/yaml
```
And import using:
```
import "github.com/ghodss/yaml"
```
Usage is very similar to the JSON library:
```go
package main
import (
"fmt"
"github.com/ghodss/yaml"
)
type Person struct {
Name string `json:"name"` // Affects YAML field names too.
Age int `json:"age"`
}
func main() {
// Marshal a Person struct to YAML.
p := Person{"John", 30}
y, err := yaml.Marshal(p)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(y))
/* Output:
age: 30
name: John
*/
// Unmarshal the YAML back into a Person struct.
var p2 Person
err = yaml.Unmarshal(y, &p2)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(p2)
/* Output:
{John 30}
*/
}
```
`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
```go
package main
import (
"fmt"
"github.com/ghodss/yaml"
)
func main() {
j := []byte(`{"name": "John", "age": 30}`)
y, err := yaml.JSONToYAML(j)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(y))
/* Output:
name: John
age: 30
*/
j2, err := yaml.YAMLToJSON(y)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(j2))
/* Output:
{"age":30,"name":"John"}
*/
}
```

glog
====
Leveled execution logs for Go.
This is an efficient pure Go implementation of leveled logs in the
manner of the open source C++ package
https://github.com/google/glog
By binding methods to booleans it is possible to use the log package
without paying the expense of evaluating the arguments to the log.
Through the -vmodule flag, the package also provides fine-grained
control over logging at the file level.
The comment from glog.go introduces the ideas:
Package glog implements logging analogous to the Google-internal
C++ INFO/ERROR/V setup. It provides functions Info, Warning,
Error, Fatal, plus formatting variants such as Infof. It
also provides V-style logging controlled by the -v and
-vmodule=file=2 flags.
Basic examples:
glog.Info("Prepare to repel boarders")
glog.Fatalf("Initialization failed: %s", err)
See the documentation for the V function for an explanation
of these examples:
if glog.V(2) {
glog.Info("Starting transaction...")
}
glog.V(2).Infoln("Processed", nItems, "elements")
The repository contains an open source version of the log package
used inside Google. The master copy of the source lives inside
Google, not here. The code in this repo is for export only and is not itself
under development. Feature requests will be ignored.

[![Build Status](https://travis-ci.org/hpcloud/tail.svg)](https://travis-ci.org/hpcloud/tail)
[![Build status](https://ci.appveyor.com/api/projects/status/kohpsf3rvhjhrox6?svg=true)](https://ci.appveyor.com/project/HelionCloudFoundry/tail)
# Go package for tail-ing files
A Go package striving to emulate the features of the BSD `tail` program.
```Go
t, err := tail.TailFile("/var/log/nginx.log", tail.Config{Follow: true})
for line := range t.Lines {
fmt.Println(line.Text)
}
```
See [API documentation](http://godoc.org/github.com/hpcloud/tail).
## Log rotation
Tail comes with full support for truncation/move detection as it is
designed to work with log rotation tools.
## Installing
go get github.com/hpcloud/tail/...
## Windows support
This package [needs assistance](https://github.com/hpcloud/tail/labels/Windows) for full Windows support.

- Replace GOPATH in Environment [4b883f0]
## 1.4.0 7/16/2017
- `ginkgo` now provides a hint if you accidentally forget to run `ginkgo bootstrap` to generate a `*_suite_test.go` file that actually invokes the Ginkgo test runner. [#345](https://github.com/onsi/ginkgo/pull/345)
- thanks to improvements in `go test -c` `ginkgo` no longer needs to fix Go's compilation output to ensure compilation errors are expressed relative to the CWD. [#357]
- `ginkgo watch -watchRegExp=...` allows you to specify a custom regular expression to watch. Only files matching the regular expression are watched for changes (the default is `\.go$`) [#356]
- `ginkgo` now always emits compilation output. Previously, only failed compilation output was printed out. [#277]
- `ginkgo -requireSuite` now fails the test run if there are `*_test.go` files but `go test` fails to detect any tests. Typically this means you forgot to run `ginkgo bootstrap` to generate a suite file. [#344]
- `ginkgo -timeout=DURATION` allows you to adjust the timeout for the entire test suite (default is 24 hours) [#248]
## 1.3.0 3/28/2017
Improvements:
- Significantly improved parallel test distribution. Now instead of pre-sharding test cases across workers (which can result in idle workers and poor test performance) Ginkgo uses a shared queue to keep all workers busy until all tests are complete. This improves test-time performance and consistency.
- `Skip(message)` can be used to skip the current test.
- Added `extensions/table` - a Ginkgo DSL for [Table Driven Tests](http://onsi.github.io/ginkgo/#table-driven-tests)
- Add `GinkgoRandomSeed()` - shorthand for `config.GinkgoConfig.RandomSeed`
- Support for retrying flaky tests with `--flakeAttempts`
- `ginkgo ./...` now recurses as you'd expect
- Added `Specify` a synonym for `It`
- Support colorise on Windows
- Broader support for various go compilation flags in the `ginkgo` CLI
Bug Fixes:
- Ginkgo tests now fail when you `panic(nil)` (#167)
## 1.2.0 5/31/2015
Improvements
- `ginkgo -coverpkg` calls down to `go test -coverpkg` (#160)
- `ginkgo -afterSuiteHook COMMAND` invokes the passed-in `COMMAND` after a test suite completes (#152)
- Relaxed requirement for Go 1.4+. `ginkgo` now works with Go v1.3+ (#166)
## 1.2.0-beta
Ginkgo now requires Go 1.4+
Improvements:
- Call reporters in reverse order when announcing spec completion -- allows custom reporters to emit output before the default reporter does.
- Improved focus behavior. Now, this:
```golang
FDescribe("Some describe", func() {
It("A", func() {})
FIt("B", func() {})
})
```
will run `B` but *not* `A`. This tends to be a common usage pattern when in the thick of writing and debugging tests.
- When `SIGINT` is received, Ginkgo will emit the contents of the `GinkgoWriter` before running the `AfterSuite`. Useful for debugging stuck tests.
- When `--progress` is set, Ginkgo will write test progress (in particular, Ginkgo will say when it is about to run a BeforeEach, AfterEach, It, etc...) to the `GinkgoWriter`. This is useful for debugging stuck tests and tests that generate many logs.
- Improved output when an error occurs in a setup or teardown block.
- When `--dryRun` is set, Ginkgo will walk the spec tree and emit to its reporter *without* actually running anything. Best paired with `-v` to understand which specs will run in which order.
- Add `By` to help document long `It`s. `By` simply writes to the `GinkgoWriter`.
- Add support for precompiled tests:
- `ginkgo build <path-to-package>` will now compile the package, producing a file named `package.test`
- The compiled `package.test` file can be run directly. This runs the tests in series.
- To run precompiled tests in parallel, you can run: `ginkgo -p package.test`
- Support `bootstrap`ping and `generate`ing [Agouti](http://agouti.org) specs.
- `ginkgo generate` and `ginkgo bootstrap` now honor the package name already defined in a given directory
- The `ginkgo` CLI ignores `SIGQUIT`. Prevents its stack dump from interlacing with the underlying test suite's stack dump.
- The `ginkgo` CLI now compiles tests into a temporary directory instead of the package directory. This necessitates upgrading to Go v1.4+.
- `ginkgo -notify` now works on Linux
Bug Fixes:
- If --skipPackages is used and all packages are skipped, Ginkgo should exit 0.
- Fix tempfile leak when running in parallel
- Fix incorrect failure message when a panic occurs during a parallel test run
- Fixed an issue where a pending test within a focused context (or a focused test within a pending context) would skip all other tests.
- Be more consistent about handling SIGTERM as well as SIGINT
- When interupted while concurrently compiling test suites in the background, Ginkgo now cleans up the compiled artifacts.
- Fixed a long standing bug where `ginkgo -p` would hang if a process spawned by one of the Ginkgo parallel nodes does not exit. (Hooray!)
## 1.1.0 (8/2/2014)
No changes, just dropping the beta.
## 1.1.0-beta (7/22/2014)
New Features:
- `ginkgo watch` now monitors packages *and their dependencies* for changes. The depth of the dependency tree can be modified with the `-depth` flag.
- Test suites with a programmatic focus (`FIt`, `FDescribe`, etc...) exit with non-zero status code, even when they pass. This allows CI systems to detect accidental commits of focused test suites.
- `ginkgo -p` runs the testsuite in parallel with an auto-detected number of nodes.
- `ginkgo -tags=TAG_LIST` passes a list of tags down to the `go build` command.
- `ginkgo --failFast` aborts the test suite after the first failure.
- `ginkgo generate file_1 file_2` can take multiple file arguments.
- Ginkgo now summarizes any spec failures that occured at the end of the test run.
- `ginkgo --randomizeSuites` will run tests *suites* in random order using the generated/passed-in seed.
Improvements:
- `ginkgo -skipPackage` now takes a comma-separated list of strings. If the *relative path* to a package matches one of the entries in the comma-separated list, that package is skipped.
- `ginkgo --untilItFails` no longer recompiles between attempts.
- Ginkgo now panics when a runnable node (`It`, `BeforeEach`, `JustBeforeEach`, `AfterEach`, `Measure`) is nested within another runnable node. This is always a mistake. Any test suites that panic because of this change should be fixed.
Bug Fixes:
- `ginkgo boostrap` and `ginkgo generate` no longer fail when dealing with `hyphen-separated-packages`.
- parallel specs are now better distributed across nodes - fixed a crashing bug where (for example) distributing 11 tests across 7 nodes would panic
## 1.0.0 (5/24/2014)
New Features:
- Add `GinkgoParallelNode()` - shorthand for `config.GinkgoConfig.ParallelNode`
Improvements:
- When compilation fails, the compilation output is rewritten to present a correct *relative* path. Allows ⌘-clicking in iTerm open the file in your text editor.
- `--untilItFails` and `ginkgo watch` now generate new random seeds between test runs, unless a particular random seed is specified.
Bug Fixes:
- `-cover` now generates a correctly combined coverprofile when running with in parallel with multiple `-node`s.
- Print out the contents of the `GinkgoWriter` when `BeforeSuite` or `AfterSuite` fail.
- Fix all remaining race conditions in Ginkgo's test suite.
## 1.0.0-beta (4/14/2014)
Breaking changes:
- `thirdparty/gomocktestreporter` is gone. Use `GinkgoT()` instead
- Modified the Reporter interface
- `watch` is now a subcommand, not a flag.
DSL changes:
- `BeforeSuite` and `AfterSuite` for setting up and tearing down test suites.
- `AfterSuite` is triggered on interrupt (`^C`) as well as exit.
- `SynchronizedBeforeSuite` and `SynchronizedAfterSuite` for setting up and tearing down singleton resources across parallel nodes.
CLI changes:
- `watch` is now a subcommand, not a flag
- `--nodot` flag can be passed to `ginkgo generate` and `ginkgo bootstrap` to avoid dot imports. This explicitly imports all exported identifiers in Ginkgo and Gomega. Refreshing this list can be done by running `ginkgo nodot`
- Additional arguments can be passed to specs. Pass them after the `--` separator
- `--skipPackage` flag takes a regexp and ignores any packages with package names passing said regexp.
- `--trace` flag prints out full stack traces when errors occur, not just the line at which the error occurs.
Misc:
- Start using semantic versioning
- Start maintaining changelog
Major refactor:
- Pull out Ginkgo's internal to `internal`
- Rename `example` everywhere to `spec`
- Much more!

# Contributing to Ginkgo
Your contributions to Ginkgo are essential for its long-term maintenance and improvement.
- Please **open an issue first** - describe what problem you are trying to solve and give the community a forum for input and feedback ahead of investing time in writing code!
- Ensure adequate test coverage:
- When adding to the Ginkgo library, add unit and/or integration tests (under the `integration` folder).
- When adding to the Ginkgo CLI, note that there are very few unit tests. Please add an integration test.
- Update the documentation. Ginko uses `godoc` comments and documentation on the `gh-pages` branch.
If relevant, please submit a docs PR to that branch alongside your code PR.
Thanks for supporting Ginkgo!

![Ginkgo: A Go BDD Testing Framework](http://onsi.github.io/ginkgo/images/ginkgo.png)
[![Build Status](https://travis-ci.org/onsi/ginkgo.svg?branch=master)](https://travis-ci.org/onsi/ginkgo)
Jump to the [docs](http://onsi.github.io/ginkgo/) to learn more. To start rolling your Ginkgo tests *now* [keep reading](#set-me-up)!
If you have a question, comment, bug report, feature request, etc. please open a GitHub issue.
## Feature List
- Ginkgo uses Go's `testing` package and can live alongside your existing `testing` tests. It's easy to [bootstrap](http://onsi.github.io/ginkgo/#bootstrapping-a-suite) and start writing your [first tests](http://onsi.github.io/ginkgo/#adding-specs-to-a-suite)
- Structure your BDD-style tests expressively:
- Nestable [`Describe`, `Context` and `When` container blocks](http://onsi.github.io/ginkgo/#organizing-specs-with-containers-describe-and-context)
- [`BeforeEach` and `AfterEach` blocks](http://onsi.github.io/ginkgo/#extracting-common-setup-beforeeach) for setup and teardown
- [`It` and `Specify` blocks](http://onsi.github.io/ginkgo/#individual-specs-) that hold your assertions
- [`JustBeforeEach` blocks](http://onsi.github.io/ginkgo/#separating-creation-and-configuration-justbeforeeach) that separate creation from configuration (also known as the subject action pattern).
- [`BeforeSuite` and `AfterSuite` blocks](http://onsi.github.io/ginkgo/#global-setup-and-teardown-beforesuite-and-aftersuite) to prep for and cleanup after a suite.
- A comprehensive test runner that lets you:
- Mark specs as [pending](http://onsi.github.io/ginkgo/#pending-specs)
- [Focus](http://onsi.github.io/ginkgo/#focused-specs) individual specs, and groups of specs, either programmatically or on the command line
- Run your tests in [random order](http://onsi.github.io/ginkgo/#spec-permutation), and then reuse random seeds to replicate the same order.
- Break up your test suite into parallel processes for straightforward [test parallelization](http://onsi.github.io/ginkgo/#parallel-specs)
- `ginkgo`: a command line interface with plenty of handy command line arguments for [running your tests](http://onsi.github.io/ginkgo/#running-tests) and [generating](http://onsi.github.io/ginkgo/#generators) test files. Here are a few choice examples:
- `ginkgo -nodes=N` runs your tests in `N` parallel processes and print out coherent output in realtime
- `ginkgo -cover` runs your tests using Go's code coverage tool
- `ginkgo convert` converts an XUnit-style `testing` package to a Ginkgo-style package
- `ginkgo -focus="REGEXP"` and `ginkgo -skip="REGEXP"` allow you to specify a subset of tests to run via regular expression
- `ginkgo -r` runs all tests suites under the current directory
- `ginkgo -v` prints out identifying information for each tests just before it runs
And much more: run `ginkgo help` for details!
The `ginkgo` CLI is convenient, but purely optional -- Ginkgo works just fine with `go test`
- `ginkgo watch` [watches](https://onsi.github.io/ginkgo/#watching-for-changes) packages *and their dependencies* for changes, then reruns tests. Run tests immediately as you develop!
- Built-in support for testing [asynchronicity](http://onsi.github.io/ginkgo/#asynchronous-tests)
- Built-in support for [benchmarking](http://onsi.github.io/ginkgo/#benchmark-tests) your code. Control the number of benchmark samples as you gather runtimes and other, arbitrary, bits of numerical information about your code.
- [Completions for Sublime Text](https://github.com/onsi/ginkgo-sublime-completions): just use [Package Control](https://sublime.wbond.net/) to install `Ginkgo Completions`.
- [Completions for VSCode](https://github.com/onsi/vscode-ginkgo): just use VSCode's extension installer to install `vscode-ginkgo`.
- Straightforward support for third-party testing libraries such as [Gomock](https://code.google.com/p/gomock/) and [Testify](https://github.com/stretchr/testify). Check out the [docs](http://onsi.github.io/ginkgo/#third-party-integrations) for details.
- A modular architecture that lets you easily:
- Write [custom reporters](http://onsi.github.io/ginkgo/#writing-custom-reporters) (for example, Ginkgo comes with a [JUnit XML reporter](http://onsi.github.io/ginkgo/#generating-junit-xml-output) and a TeamCity reporter).
- [Adapt an existing matcher library (or write your own!)](http://onsi.github.io/ginkgo/#using-other-matcher-libraries) to work with Ginkgo
## [Gomega](http://github.com/onsi/gomega): Ginkgo's Preferred Matcher Library
Ginkgo is best paired with Gomega. Learn more about Gomega [here](http://onsi.github.io/gomega/)
## [Agouti](http://github.com/sclevine/agouti): A Go Acceptance Testing Framework
Agouti allows you run WebDriver integration tests. Learn more about Agouti [here](http://agouti.org)
## Set Me Up!
You'll need the Go command-line tools. Ginkgo is tested with Go 1.6+, but preferably you should get the latest. Follow the [installation instructions](https://golang.org/doc/install) if you don't have it installed.
```bash
go get -u github.com/onsi/ginkgo/ginkgo # installs the ginkgo CLI
go get -u github.com/onsi/gomega/... # fetches the matcher library
cd path/to/package/you/want/to/test
ginkgo bootstrap # set up a new ginkgo suite
ginkgo generate # will create a sample test file. edit this file and add your tests then...
go test # to run your tests
ginkgo # also runs your tests
```
## I'm new to Go: What are my testing options?
Of course, I heartily recommend [Ginkgo](https://github.com/onsi/ginkgo) and [Gomega](https://github.com/onsi/gomega). Both packages are seeing heavy, daily, production use on a number of projects and boast a mature and comprehensive feature-set.
With that said, it's great to know what your options are :)
### What Go gives you out of the box
Testing is a first class citizen in Go, however Go's built-in testing primitives are somewhat limited: The [testing](http://golang.org/pkg/testing) package provides basic XUnit style tests and no assertion library.
### Matcher libraries for Go's XUnit style tests
A number of matcher libraries have been written to augment Go's built-in XUnit style tests. Here are two that have gained traction:
- [testify](https://github.com/stretchr/testify)
- [gocheck](http://labix.org/gocheck)
You can also use Ginkgo's matcher library [Gomega](https://github.com/onsi/gomega) in [XUnit style tests](http://onsi.github.io/gomega/#using-gomega-with-golangs-xunitstyle-tests)
### BDD style testing frameworks
There are a handful of BDD-style testing frameworks written for Go. Here are a few:
- [Ginkgo](https://github.com/onsi/ginkgo) ;)
- [GoConvey](https://github.com/smartystreets/goconvey)
- [Goblin](https://github.com/franela/goblin)
- [Mao](https://github.com/azer/mao)
- [Zen](https://github.com/pranavraja/zen)
Finally, @shageman has [put together](https://github.com/shageman/gotestit) a comprehensive comparison of Go testing libraries.
Go explore!

A Ginkgo release is a tagged git sha and a GitHub release. To cut a release:
1. Ensure CHANGELOG.md is up to date.
- Use `git log --pretty=format:'- %s [%h]' HEAD...vX.X.X` to list all the commits since the last release
- Categorize the changes into
- Breaking Changes (requires a major version)
- New Features (minor version)
- Fixes (fix version)
- Maintenance (which in general should not be mentioned in `CHANGELOG.md` as they have no user impact)
1. Update `VERSION` in `config/config.go`
1. Create a commit with the version number as the commit message (e.g. `v1.3.0`)
1. Tag the commit with the version number as the tag name (e.g. `v1.3.0`)
1. Push the commit and tag to GitHub
1. Create a new [GitHub release](https://help.github.com/articles/creating-releases/) with the version number as the tag (e.g. `v1.3.0`). List the key changes in the release notes.
