## go.rice
[![Build Status](https://travis-ci.org/GeertJohan/go.rice.png)](https://travis-ci.org/GeertJohan/go.rice)
[![Godoc](https://img.shields.io/badge/godoc-go.rice-blue.svg?style=flat-square)](https://godoc.org/github.com/GeertJohan/go.rice)
go.rice is a [Go](http://golang.org) package that makes working with resources such as html,js,css,images and templates very easy. During development `go.rice` will load required files directly from disk. Upon deployment it is easy to add all resource files to a executable using the `rice` tool, without changing the source code for your package. go.rice provides several methods to add resources to a binary.
### What does it do?
The first thing go.rice does is finding the correct absolute path for your resource files. Say you are executing go binary in your home directory, but your `html-files` are located in `$GOPATH/src/yourApplication/html-files`. `go.rice` will lookup the correct path for that directory (relative to the location of yourApplication). The only thing you have to do is include the resources using `rice.FindBox("html-files")`.
This only works when the source is available to the machine executing the binary. Which is always the case when the binary was installed with `go get` or `go install`. It might occur that you wish to simply provide a binary, without source. The `rice` tool analyses source code and finds call's to `rice.FindBox(..)` and adds the required directories to the executable binary. There are several methods to add these resources. You can 'embed' by generating go source code, or append the resource to the executable as zip file. In both cases `go.rice` will detect the embedded or appended resources and load those, instead of looking up files from disk.
### Installation
Use `go get` to install the package the `rice` tool.
```
go get github.com/GeertJohan/go.rice
go get github.com/GeertJohan/go.rice/rice
```
### Package usage
Import the package: `import "github.com/GeertJohan/go.rice"`
**Serving a static content folder over HTTP with a rice Box**
```go
http.Handle("/", http.FileServer(rice.MustFindBox("http-files").HTTPBox()))
http.ListenAndServe(":8080", nil)
```
**Service a static content folder over HTTP at a non-root location**
```go
box := rice.MustFindBox("cssfiles")
cssFileServer := http.StripPrefix("/css/", http.FileServer(box.HTTPBox()))
http.Handle("/css/", cssFileServer)
http.ListenAndServe(":8080", nil)
```
Note the *trailing slash* in `/css/` in both the call to
`http.StripPrefix` and `http.Handle`.
**Loading a template**
```go
// find a rice.Box
templateBox, err := rice.FindBox("example-templates")
if err != nil {
log.Fatal(err)
}
// get file contents as string
templateString, err := templateBox.String("message.tmpl")
if err != nil {
log.Fatal(err)
}
// parse and execute the template
tmplMessage, err := template.New("message").Parse(templateString)
if err != nil {
log.Fatal(err)
}
tmplMessage.Execute(os.Stdout, map[string]string{"Message": "Hello, world!"})
```
Never call `FindBox()` or `MustFindBox()` from an `init()` function, as the boxes might have not been loaded at that time.
### Tool usage
The `rice` tool lets you add the resources to a binary executable so the files are not loaded from the filesystem anymore. This creates a 'standalone' executable. There are several ways to add the resources to a binary, each has pro's and con's but all will work without requiring changes to the way you load the resources.
#### embed-go
**Embed resources by generating Go source code**
This method must be executed before building. It generates a single Go source file called *rice-box.go* for each package, that is compiled by the go compiler into the binary.
The downside with this option is that the generated go source files can become very large, which will slow down compilation and require lots of memory to compile.
Execute the following commands:
```
rice embed-go
go build
```
*A Note on Symbolic Links*: `embed-go` uses the `os.Walk` function
from the standard library. The `os.Walk` function does **not** follow
symbolic links. So, when creating a box, be aware that any symbolic
links inside your box's directory will not be followed. **However**,
if the box itself is a symbolic link, its actual location will be
resolved first and then walked. In summary, if your box location is a
symbolic link, it will be followed but none of the symbolic links in
the box will be followed.
#### embed-syso
**Embed resources by generating a coff .syso file and some .go source code**
** This method is experimental and should not be used for production systems just yet **
This method must be executed before building. It generates a COFF .syso file and Go source file that are compiled by the go compiler into the binary.
Execute the following commands:
```
rice embed-syso
go build
```
#### append
**Append resources to executable as zip file**
This method changes an already built executable. It appends the resources as zip file to the binary. It makes compilation a lot faster and can be used with large resource files.
Downsides for appending are that it requires `zip` to be installed and does not provide a working Seek method.
Run the following commands to create a standalone executable.
```
go build -o example
rice append --exec example
```
**Note: requires zip command to be installed**
On windows, install zip from http://gnuwin32.sourceforge.net/packages/zip.htm or cygwin/msys toolsets.
#### Help information
Run `rice -h` for information about all options.
You can run the -h option for each sub-command, e.g. `rice append -h`.
### Order of precedence
When opening a new box, the rice package tries to locate the resources in the following order:
- embedded in generated go source
- appended as zip
- 'live' from filesystem
### License
This project is licensed under a Simplified BSD license. Please read the [LICENSE file][license].
### TODO & Development
This package is not completed yet. Though it already provides working embedding, some important featuers are still missing.
- implement Readdir() correctly on virtualDir
- in-code TODO's
- find boxes in imported packages
Less important stuff:
- idea, os/arch dependent embeds. rice checks if embedding file has _os_arch or build flags. If box is not requested by file without buildflags, then the buildflags are applied to the embed file.

# manhole
An opinionated HTTP manhole into Go processes.
## Assumptions This Package Makes
- Make each server instance have a unique HTTP port that is randomized by default.
This makes it very hard to accidentally route this manhole to the outside world.
If more assurance is required I personally suggest using [yubikey totp][yktotp],
but do research.
- Application code does not touch [`http.DefaultServeMux`][default-servemux]'. This is so that
administative control rods can be dynamically flipped in the case they are
needed.
- [pprof][pprof] endpoints added to `http.DefaultServeMux`. This allows easy
access to [pprof runtime tracing][pprof-tracing] to debug issues on long-running
applications like HTTP services.
- Make the manhole slightly inconvenient to put into place in production. This
helps make sure that this tool remains a debugging tool and not a part of a
long-term production rollout.
## Usage
Compile this as a plugin:
```console
$ go get -d github.com/Xe/gopreload/manhole
$ go build -buildmode plugin -o manhole.so github.com/Xe/gopreload/manhole
```
Then add [`gopreload`][gopreload] to your application:
```go
// gopreload.go
package main
/*
This file is separate to make it very easy to both add into an application, but
also very easy to remove.
*/
import _ "github.com/Xe/gopreload"
```
And at runtime add the `manhole.so` file you created earlier to the target system
somehow and add the following environment variable to its run configuration:
```sh
GO_PRELOAD=/path/to/manhole.so
```

Package spew implements a deep pretty printer for Go data structures to aid in
debugging.
A quick overview of the additional features spew provides over the built-in
printing facilities for Go data types are as follows:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output (only when using
Dump style)
There are two different approaches spew allows for dumping Go data structures:
* Dump style which prints with newlines, customizable indentation,
and additional debug information such as types and all pointer addresses
used to indirect to the final value
* A custom Formatter interface that integrates cleanly with the standard fmt
package and replaces %v, %+v, %#v, and %#+v to provide inline printing
similar to the default %v while providing the additional functionality
outlined above and passing unsupported format verbs such as %x and %q
along to fmt
Quick Start
This section demonstrates how to quickly get started with spew. See the
sections below for further details on formatting and configuration options.
To dump a variable with full newlines, indentation, type, and pointer
information use Dump, Fdump, or Sdump:
spew.Dump(myVar1, myVar2, ...)
spew.Fdump(someWriter, myVar1, myVar2, ...)
str := spew.Sdump(myVar1, myVar2, ...)
Alternatively, if you would prefer to use format strings with a compacted inline
printing style, use the convenience wrappers Printf, Fprintf, etc with
%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
%#+v (adds types and pointer addresses):
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
Configuration Options
Configuration of spew is handled by fields in the ConfigState type. For
convenience, all of the top-level functions use a global state available
via the spew.Config global.
It is also possible to create a ConfigState instance that provides methods
equivalent to the top-level functions. This allows concurrent configuration
options. See the ConfigState documentation for more details.
The following configuration options are available:
* Indent
String to use for each indentation level for Dump functions.
It is a single space by default. A popular alternative is "\t".
* MaxDepth
Maximum number of levels to descend into nested data structures.
There is no limit by default.
* DisableMethods
Disables invocation of error and Stringer interface methods.
Method invocation is enabled by default.
* DisablePointerMethods
Disables invocation of error and Stringer interface methods on types
which only accept pointer receivers from non-pointer variables.
Pointer method invocation is enabled by default.
* DisablePointerAddresses
DisablePointerAddresses specifies whether to disable the printing of
pointer addresses. This is useful when diffing data structures in tests.
* DisableCapacities
DisableCapacities specifies whether to disable the printing of
capacities for arrays, slices, maps and channels. This is useful when
diffing data structures in tests.
* ContinueOnMethod
Enables recursion into types after invoking error and Stringer interface
methods. Recursion after method invocation is disabled by default.
* SortKeys
Specifies map keys should be sorted before being printed. Use
this to have a more deterministic, diffable output. Note that
only native types (bool, int, uint, floats, uintptr and string)
and types which implement error or Stringer interfaces are
supported with other types sorted according to the
reflect.Value.String() output which guarantees display
stability. Natural map order is used by default.
* SpewKeys
Specifies that, as a last resort attempt, map keys should be
spewed to strings and sorted by those strings. This is only
considered if SortKeys is true.
Dump Usage
Simply call spew.Dump with a list of variables you want to dump:
spew.Dump(myVar1, myVar2, ...)
You may also call spew.Fdump if you would prefer to output to an arbitrary
io.Writer. For example, to dump to standard error:
spew.Fdump(os.Stderr, myVar1, myVar2, ...)
A third option is to call spew.Sdump to get the formatted output as a string:
str := spew.Sdump(myVar1, myVar2, ...)
Sample Dump Output
See the Dump example for details on the setup of the types and variables being
shown here.
(main.Foo) {
unexportedField: (*main.Bar)(0xf84002e210)({
flag: (main.Flag) flagTwo,
data: (uintptr) <nil>
}),
ExportedField: (map[interface {}]interface {}) (len=1) {
(string) (len=3) "one": (bool) true
}
}
Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
command as shown.
([]uint8) (len=32 cap=32) {
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
00000020 31 32 |12|
}
Custom Formatter
Spew provides a custom formatter that implements the fmt.Formatter interface
so that it integrates cleanly with standard fmt package printing functions. The
formatter is useful for inline printing of smaller data types similar to the
standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Custom Formatter Usage
The simplest way to make use of the spew custom formatter is to call one of the
convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
functions have syntax you are most likely already familiar with:
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Println(myVar, myVar2)
spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
See the Index for the full list convenience functions.
Sample Formatter Output
Double pointer to a uint8:
%v: <**>5
%+v: <**>(0xf8400420d0->0xf8400420c8)5
%#v: (**uint8)5
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
Pointer to circular struct with a uint8 field and a pointer to itself:
%v: <*>{1 <*><shown>}
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
See the Printf example for details on the setup of variables being shown
here.
Errors
Since it is possible for custom Stringer/error interfaces to panic, spew
detects them and handles them internally by printing the panic information
inline with the output. Since spew is intended to provide deep pretty printing
capabilities on structures, it intentionally does not return any errors.

Dump displays the passed parameters to standard out with newlines, customizable
indentation, and additional debug information such as complete types and all
pointer addresses used to indirect to the final value. It provides the
following features over the built-in printing facilities provided by the fmt
package:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output
The configuration options are controlled by an exported package global,
spew.Config. See ConfigState for options documentation.
See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
get the formatted result as a string.

NewFormatter returns a custom formatter that satisfies the fmt.Formatter
interface. As a result, it integrates cleanly with standard fmt package
printing functions. The formatter is useful for inline printing of smaller data
types similar to the standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Typically this function shouldn't be called directly. It is much easier to make
use of the custom formatter by calling one of the convenience functions such as
Printf, Println, or Fprintf.

# gops
[![Build status](https://circleci.com/gh/google/gops/tree/master.svg?style=shield&circle-token=2637dc1e57d5407ae250480a86a2e553a7d20482)](https://circleci.com/gh/google/gops)
[![GoDoc](https://godoc.org/github.com/google/gops/agent?status.svg)](https://godoc.org/github.com/google/gops/agent)
gops is a command to list and diagnose Go processes currently running on your system.
```
$ gops
983 uplink-soecks (/usr/local/bin/uplink-soecks)
52697 gops (/Users/jbd/bin/gops)
4132* foops (/Users/jbd/bin/foops)
51130 gocode (/Users/jbd/bin/gocode)
```
## Installation
```
$ go get -u github.com/google/gops
```
## Diagnostics
For processes that starts the diagnostics agent, gops can report
additional information such as the current stack trace, Go version, memory
stats, etc.
In order to start the diagnostics agent, see the [hello example](https://github.com/google/gops/blob/master/examples/hello/main.go).
``` go
package main
import (
"log"
"time"
"github.com/google/gops/agent"
)
func main() {
if err := agent.Listen(nil); err != nil {
log.Fatal(err)
}
time.Sleep(time.Hour)
}
```
### Manual
It is possible to use gops tool both in local and remote mode.
Local mode requires that you start the target binary as the same user that runs gops binary.
To use gops in a remote mode you need to know target's agent address.
In Local mode use process's PID as a target; in Remote mode target is a `host:port` combination.
#### 0. Listing all processes running locally
To print all go processes, run `gops` without arguments:
```sh
$ gops
983 uplink-soecks (/usr/local/bin/uplink-soecks)
52697 gops (/Users/jbd/bin/gops)
4132* foops (/Users/jbd/bin/foops)
51130 gocode (/Users/jbd/bin/gocode)
```
Note that processes running the agent are marked with `*` next to the PID (e.g. `4132*`).
#### $ gops stack (\<pid\>|\<addr\>)
In order to print the current stack trace from a target program, run the following command:
```sh
$ gops stack (<pid>|<addr>)
gops stack 85709
goroutine 8 [running]:
runtime/pprof.writeGoroutineStacks(0x13c7bc0, 0xc42000e008, 0xc420ec8520, 0xc420ec8520)

# ...
```
#### $ gops memstats (\<pid\>|\<addr\>)
To print the current memory stats, run the following command:
```sh
$ gops memstats (<pid>|<addr>)
```
#### $ gops gc (\<pid\>|\<addr\>)
If you want to force run garbage collection on the target program, run `gc`.
It will block until the GC is completed.
#### $ gops version (\<pid\>|\<addr\>)
gops reports the Go version the target program is built with, if you run the following:
```sh
$ gops version (<pid>|<addr>)
devel +6a3c6c0 Sat Jan 14 05:57:07 2017 +0000
```
#### $ gops stats (\<pid\>|\<addr\>)
To print the runtime statistics such as number of goroutines and `GOMAXPROCS`.
#### Profiling
##### Pprof
gops supports CPU and heap pprof profiles. After reading either heap or CPU profile,
it shells out to the `go tool pprof` and let you interatively examine the profiles.
To enter the CPU profile, run:
```sh
$ gops pprof-cpu (<pid>|<addr>)
```
To enter the heap profile, run:
```sh
$ gops pprof-heap (<pid>|<addr>)
```
##### Execution trace
gops allows you to start the runtime tracer for 5 seconds and examine the results.
```sh
$ gops trace (<pid>|<addr>)
```
