BPF's main use is to specify a packet filter for network taps, so that the kernel doesn't have to expensively copy every packet it sees to userspace. However, it's been repurposed to other areas where running user code in-kernel is needed. For example, Linux's seccomp uses BPF to apply security policies to system calls. For simplicity, this documentation refers only to packets, but other uses of BPF have their own data payloads. BPF programs run in a restricted virtual machine. It has almost no access to kernel functions, and while conditional branches are allowed, they can only jump forwards, to guarantee that there are no infinite loops. The virtual machine The BPF VM is an accumulator machine. Its main register, called register A, is an implicit source and destination in all arithmetic and logic operations. The machine also has 16 scratch registers for temporary storage, and an indirection register (register X) for indirect memory access. All registers are 32 bits wide. Each run of a BPF program is given one packet, which is placed in the VM's read-only "main memory". LoadAbsolute and LoadIndirect instructions can fetch up to 32 bits at a time into register A for examination. The goal of a BPF program is to produce and return a verdict (uint32), which tells the kernel what to do with the packet. In the context of packet filtering, the returned value is the number of bytes of the packet to forward to userspace, or 0 to ignore the packet. Other contexts like seccomp define their own return values. In order to simplify programs, attempts to read past the end of the packet terminate the program execution with a verdict of 0 (ignore packet). This means that the vast majority of BPF programs don't need to do any explicit bounds checking. In addition to the bytes of the packet, some BPF programs have access to extensions, which are essentially calls to kernel utility functions. Currently, the only extensions supported by this package are the Linux packet filter extensions. Examples This packet filter selects all ARP packets. bpf.Assemble([]bpf.Instruction{ // Load "EtherType" field from the ethernet header. bpf.LoadAbsolute{Off: 12, Size: 2}, // Skip over the next instruction if EtherType is not ARP. bpf.JumpIf{Cond: bpf.JumpNotEqual, Val: 0x0806, SkipTrue: 1}, // Verdict is "send up to 4k of the packet to userspace." bpf.RetConstant{Val: 4096}, // Verdict is "ignore packet." bpf.RetConstant{Val: 0}, }) This packet filter captures a random 1% sample of traffic. bpf.Assemble([]bpf.Instruction{ // Get a 32-bit random number from the Linux kernel. bpf.LoadExtension{Num: bpf.ExtRand}, // 1% dice roll? bpf.JumpIf{Cond: bpf.JumpLessThan, Val: 2^32/100, SkipFalse: 1}, // Capture. bpf.RetConstant{Val: 4096}, // Ignore. bpf.RetConstant{Val: 0}, }) */ package bpf // import "golang.org/x/net/bpf" golang-golang-x-net-dev-0.0+git20190811.74dc4d7+dfsg/bpf/instructions.go000066400000000000000000000432671352576555200251720ustar00rootroot00000000000000// Copyright 2016 The Go Authors.

HTTP charset

 

The character encoding of a page can be set using the HTTP header charset declaration.

The test contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector .test div.ÜÀÚ. This matches the sequence of bytes above when they are interpreted as ISO 8859-15. If the class name matches the selector then the test will pass.

The only character encoding declaration for this HTML file is in the HTTP header, which sets the encoding to ISO 8859-15.

HTTP vs UTF-8 BOM

 

A character encoding set in the HTTP header has lower precedence than the UTF-8 signature.

The HTTP header attempts to set the character encoding to ISO 8859-15. The page starts with a UTF-8 signature.

The test contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector .test div.ýäè. This matches the sequence of bytes above when they are interpreted as UTF-8. If the class name matches the selector then the test will pass.

If the test is unsuccessful, the characters  should appear at the top of the page. These represent the bytes that make up the UTF-8 signature when encountered in the ISO 8859-15 encoding.

UTF-8 BOM vs meta charset

 

A page with a UTF-8 BOM will be recognized as UTF-8 even if the meta charset attribute declares a different encoding.

The page contains an encoding declaration in a meta charset attribute that attempts to set the character encoding to ISO 8859-15, but the file starts with a UTF-8 signature.

The test contains a div with a class name that contains the following sequence of bytes: 0xC3 0xBD 0xC3 0xA4 0xC3 0xA8. These represent different sequences of characters in ISO 8859-15, ISO 8859-1 and UTF-8. The external, UTF-8-encoded stylesheet contains a selector .test div.ýäè. This matches the sequence of bytes above when they are interpreted as UTF-8. If the class name matches the selector then the test will pass.

Tokenization is done by creating a Tokenizer for an io.Reader r. It is the caller's responsibility to ensure that r provides UTF-8 encoded HTML. z := html.NewTokenizer(r) Given a Tokenizer z, the HTML is tokenized by repeatedly calling z.Next(), which parses the next token and returns its type, or an error: for { tt := z.Next() if tt == html.ErrorToken { // ... return ... } // Process the current token. } There are two APIs for retrieving the current token. The high-level API is to call Token; the low-level API is to call Text or TagName / TagAttr. Both APIs allow optionally calling Raw after Next but before Token, Text, TagName, or TagAttr. In EBNF notation, the valid call sequence per token is: Next {Raw} [ Token | Text | TagName {TagAttr} ] Token returns an independent data structure that completely describes a token. Entities (such as "<") are unescaped, tag names and attribute keys are lower-cased, and attributes are collected into a []Attribute. For example: for { if z.Next() == html.ErrorToken { // Returning io.EOF indicates success. return z.Err() } emitToken(z.Token()) } The low-level API performs fewer allocations and copies, but the contents of the []byte values returned by Text, TagName and TagAttr may change on the next call to Next. For example, to extract an HTML page's anchor text: depth := 0 for { tt := z.Next() switch tt { case html.ErrorToken: return z.Err() case html.TextToken: if depth > 0 { // emitBytes should copy the []byte it receives, // if it doesn't process it immediately. emitBytes(z.Text()) } case html.StartTagToken, html.EndTagToken: tn, _ := z.TagName() if len(tn) == 1 && tn[0] == 'a' { if tt == html.StartTagToken { depth++ } else { depth-- } } } } Parsing is done by calling Parse with an io.Reader, which returns the root of the parse tree (the document element) as a *Node. It is the caller's responsibility to ensure that the Reader provides UTF-8 encoded HTML. For example, to process each anchor node in depth-first order: doc, err := html.Parse(r) if err != nil { // ... } var f func(*html.Node) f = func(n *html.Node) { if n.Type == html.ElementNode && n.Data == "a" { // Do something with n... } for c := n.FirstChild; c != nil; c = c.NextSibling { f(c) } } f(doc) The relevant specifications include: https://html.spec.whatwg.org/multipage/syntax.html and https://html.spec.whatwg.org/multipage/syntax.html#tokenization */ package html // import "golang.org/x/net/html" // The tokenization algorithm implemented by this package is not a line-by-line // transliteration of the relatively verbose state-machine in the WHATWG // specification. A more direct approach is used instead, where the program // counter implies the state, such as whether it is tokenizing a tag or a text // node. Specification compliance is verified by checking expected and actual // outputs over a test suite rather than aiming for algorithmic fidelity. // TODO(nigeltao): Does a DOM API belong in this package or a separate one? // TODO(nigeltao): How does parsing interact with a JavaScript engine? golang-golang-x-net-dev-0.0+git20190811.74dc4d7+dfsg/html/doctype.go000066400000000000000000000114751352576555200242660ustar00rootroot00000000000000// Copyright 2011 The Go Authors.

    go command [arguments]

    

    
The commands are:

    

    build       compile packages and dependencies
clean       remove object files
doc         show documentation for package or symbol
env         print Go environment information

testfunc    description of testing functions

    

    
Use "go help [topic]" for more information about that topic.

    

    Compile packages and dependencies
    

    
Usage:

    

    go build [-o output] [-i] [build flags] [packages]

    

    
Build compiles the packages named by the import paths,
along with their dependencies, but it does not install the results.

    

    
If the arguments to build are a list of .go files, build treats
them as a list of source files specifying a single package.

    

    
When compiling a single main package, build writes
the resulting executable to an output file named after
the first source file ('go build ed.go rx.go' writes 'ed' or 'ed.exe')
or the source code directory ('go build unix/sam' writes 'sam' or 'sam.exe').
The '.exe' suffix is added when writing a Windows executable.

    

    
When compiling multiple packages or a single non-main package,
build compiles the packages but discards the resulting object,
serving only as a check that the packages can be built.

    

    
When compiling packages, build ignores files that end in '_test.go'.

    

    
The -o flag, only allowed when compiling a single package,
forces build to write the resulting executable or object
to the named output file, instead of the default behavior described
in the last two paragraphs.

    

    
The -i flag installs the packages that are dependencies of the target.

    

    
The build flags are shared by the build, clean, get, install, list, run,
and test commands:

    

    -a
	force rebuilding of packages that are already up-to-date.
-n
	print the commands but do not run them.
-p n
	the number of programs, such as build commands or
	test binaries, that can be run in parallel.
	The default is the number of CPUs available.
-race
	enable data race detection.
	Supported only on linux/amd64, freebsd/amd64, darwin/amd64 and windows/amd64.
-msan
	enable interoperation with memory sanitizer.
	Supported only on linux/amd64,
	and only with Clang/LLVM as the host C compiler.
-v
	print the names of packages as they are compiled.
-work
	print the name of the temporary work directory and
	do not delete it when exiting.
-x
	print the commands.

-asmflags 'flag list'
	arguments to pass on each go tool asm invocation.
-buildmode mode
	build mode to use. See 'go help buildmode' for more.
-compiler name
	name of compiler to use, as in runtime.Compiler (gccgo or gc).
-gccgoflags 'arg list'
	arguments to pass on each gccgo compiler/linker invocation.
-gcflags 'arg list'
	arguments to pass on each go tool compile invocation.
-installsuffix suffix
	a suffix to use in the name of the package installation directory,
	in order to keep output separate from default builds.
	If using the -race flag, the install suffix is automatically set to race
	or, if set explicitly, has _race appended to it.  Likewise for the -msan
	flag.  Using a -buildmode option that requires non-default compile flags
	has a similar effect.
-ldflags 'flag list'
	arguments to pass on each go tool link invocation.
-linkshared
	link against shared libraries previously created with
	-buildmode=shared.
-pkgdir dir
	install and load all packages from dir instead of the usual locations.
	For example, when building with a non-standard configuration,
	use -pkgdir to keep generated packages in a separate location.
-tags 'tag list'
	a list of build tags to consider satisfied during the build.
	For more information about build tags, see the description of
	build constraints in the documentation for the go/build package.
-toolexec 'cmd args'
	a program to use to invoke toolchain programs like vet and asm.
	For example, instead of running asm, the go command will run
	'cmd args /path/to/asm <arguments for asm>'.

    

    
The list flags accept a space-separated list of strings. To embed spaces
in an element in the list, surround it with either single or double quotes.

    

    
For more about specifying packages, see 'go help packages'.
For more about where packages and binaries are installed,
run 'go help gopath'.
For more about calling between Go and C/C++, run 'go help c'.

    

    
Note: Build adheres to certain conventions such as those described
by 'go help gopath'. Not all projects can follow these conventions,
however. Installations that have their own conventions or that use
a separate software build system may choose to use lower-level
invocations such as 'go tool compile' and 'go tool link' to avoid
some of the overheads and design decisions of the build tool.

    

    
See also: go install, go get, go clean.

    

    Remove object files
    

    
Usage:

    

    go clean [-i] [-r] [-n] [-x] [build flags] [packages]

    

    
Clean removes object files from package source directories.
The go command builds most objects in a temporary directory,
so go clean is mainly concerned with object files left by other
tools or by manual invocations of go build.

    

    
Specifically, clean removes the following files from each of the
source directories corresponding to the import paths:

    

    _obj/            old object directory, left from Makefiles
_test/           old test directory, left from Makefiles
_testmain.go     old gotest file, left from Makefiles
test.out         old test log, left from Makefiles
build.out        old test log, left from Makefiles
*.[568ao]        object files, left from Makefiles

DIR(.exe)        from go build
DIR.test(.exe)   from go test -c
MAINFILE(.exe)   from go build MAINFILE.go
*.so             from SWIG

    

    
In the list, DIR represents the final path element of the
directory, and MAINFILE is the base name of any Go source
file in the directory that is not included when building
the package.

    

    
The -i flag causes clean to remove the corresponding installed
archive or binary (what 'go install' would create).

    

    
The -n flag causes clean to print the remove commands it would execute,
but not run them.

    

    
The -r flag causes clean to be applied recursively to all the
dependencies of the packages named by the import paths.

    

    
The -x flag causes clean to print remove commands as it executes them.

    

    
For more about build flags, see 'go help build'.

    

    
For more about specifying packages, see 'go help packages'.

    

    Show documentation for package or symbol
    

    
Usage:

    

    go doc [-u] [-c] [package|[package.]symbol[.method]]

    

    
Doc prints the documentation comments associated with the item identified by its
arguments (a package, const, func, type, var, or method) followed by a one-line
summary of each of the first-level items "under" that item (package-level
declarations for a package, methods for a type, etc.).

    

    
Doc accepts zero, one, or two arguments.

    

    
Given no arguments, that is, when run as

    

    go doc

    

    
it prints the package documentation for the package in the current directory.
If the package is a command (package main), the exported symbols of the package
are elided from the presentation unless the -cmd flag is provided.

    

    
When run with one argument, the argument is treated as a Go-syntax-like
representation of the item to be documented. What the argument selects depends
on what is installed in GOROOT and GOPATH, as well as the form of the argument,
which is schematically one of these:

    

    go doc <pkg>
go doc <sym>[.<method>]
go doc [<pkg>.]<sym>[.<method>]
go doc [<pkg>.][<sym>.]<method>

    

    
The first item in this list matched by the argument is the one whose documentation
is printed. (See the examples below.) However, if the argument starts with a capital
letter it is assumed to identify a symbol or method in the current directory.

    

    
For packages, the order of scanning is determined lexically in breadth-first order.
That is, the package presented is the one that matches the search and is nearest
the root and lexically first at its level of the hierarchy.  The GOROOT tree is
always scanned in its entirety before GOPATH.

    

    
If there is no package specified or matched, the package in the current
directory is selected, so "go doc Foo" shows the documentation for symbol Foo in
the current package.

    

    
The package path must be either a qualified path or a proper suffix of a
path. The go tool's usual package mechanism does not apply: package path
elements like . and ... are not implemented by go doc.

    

    
When run with two arguments, the first must be a full package path (not just a
suffix), and the second is a symbol or symbol and method; this is similar to the
syntax accepted by godoc:

    

    go doc <pkg> <sym>[.<method>]

    

    
In all forms, when matching symbols, lower-case letters in the argument match
either case but upper-case letters match exactly. This means that there may be
multiple matches of a lower-case argument in a package if different symbols have
different cases. If this occurs, documentation for all matches is printed.

    

    
Examples:

    

    go doc
	Show documentation for current package.
go doc Foo
	Show documentation for Foo in the current package.
	(Foo starts with a capital letter so it cannot match
	a package path.)
go doc encoding/json
	Show documentation for the encoding/json package.
go doc json
	Shorthand for encoding/json.
go doc json.Number (or go doc json.number)
	Show documentation and method summary for json.Number.
go doc json.Number.Int64 (or go doc json.number.int64)
	Show documentation for json.Number's Int64 method.
go doc cmd/doc
	Show package docs for the doc command.
go doc -cmd cmd/doc
	Show package docs and exported symbols within the doc command.
go doc template.new
	Show documentation for html/template's New function.
	(html/template is lexically before text/template)
go doc text/template.new # One argument
	Show documentation for text/template's New function.
go doc text/template new # Two arguments
	Show documentation for text/template's New function.

At least in the current tree, these invocations all print the
documentation for json.Decoder's Decode method:

go doc json.Decoder.Decode
go doc json.decoder.decode
go doc json.decode
cd go/src/encoding/json; go doc decode

    

    
Flags:

    

    -c
	Respect case when matching symbols.
-cmd
	Treat a command (package main) like a regular package.
	Otherwise package main's exported symbols are hidden
	when showing the package's top-level documentation.
-u
	Show documentation for unexported as well as exported
	symbols and methods.

    

    Print Go environment information
    

    
Usage:

    

    go env [var ...]

    

    
Env prints Go environment information.

    

    
By default env prints information as a shell script
(on Windows, a batch file).  If one or more variable
names is given as arguments,  env prints the value of
each named variable on its own line.

    

    Start a bug report
    

    
Usage:

    

    go bug

    

    
Bug opens the default browser and starts a new bug report.
The report includes useful system information.

    

    Run go tool fix on packages
    

    
Usage:

    

    go fix [packages]

    

    
Fix runs the Go fix command on the packages named by the import paths.

    

    
For more about fix, see 'go doc cmd/fix'.
For more about specifying packages, see 'go help packages'.

    

    
To run fix with specific options, run 'go tool fix'.

    

    
See also: go fmt, go vet.

    

    Run gofmt on package sources
    

    
Usage:

    

    go fmt [-n] [-x] [packages]

    

    
Fmt runs the command 'gofmt -l -w' on the packages named
by the import paths.  It prints the names of the files that are modified.

    

    
For more about gofmt, see 'go doc cmd/gofmt'.
For more about specifying packages, see 'go help packages'.

    

    
The -n flag prints commands that would be executed.
The -x flag prints commands as they are executed.

    

    
To run gofmt with specific options, run gofmt itself.

    

    
See also: go fix, go vet.

    

    Generate Go files by processing source
    

    
Usage:

    

    go generate [-run regexp] [-n] [-v] [-x] [build flags] [file.go... | packages]

    

    
Generate runs commands described by directives within existing
files. Those commands can run any process but the intent is to
create or update Go source files.

    

    
Go generate is never run automatically by go build, go get, go test,
and so on. It must be run explicitly.

    

    
Go generate scans the file for directives, which are lines of
the form,

    

    //go:generate command argument...

    

    
(note: no leading spaces and no space in "//go") where command
is the generator to be run, corresponding to an executable file
that can be run locally. It must either be in the shell path
(gofmt), a fully qualified path (/usr/you/bin/mytool), or a
command alias, described below.

    

    
Note that go generate does not parse the file, so lines that look
like directives in comments or multiline strings will be treated
as directives.

    

    
The arguments to the directive are space-separated tokens or
double-quoted strings passed to the generator as individual
arguments when it is run.

    

    
Quoted strings use Go syntax and are evaluated before execution; a
quoted string appears as a single argument to the generator.

    

    
Go generate sets several variables when it runs the generator:

    

    $GOARCH
	The execution architecture (arm, amd64, etc.)
$GOOS
	The execution operating system (linux, windows, etc.)
$GOFILE
	The base name of the file.
$GOLINE
	The line number of the directive in the source file.
$GOPACKAGE
	The name of the package of the file containing the directive.
$DOLLAR
	A dollar sign.

    

    
Other than variable substitution and quoted-string evaluation, no
special processing such as "globbing" is performed on the command
line.

    

    
As a last step before running the command, any invocations of any
environment variables with alphanumeric names, such as $GOFILE or
$HOME, are expanded throughout the command line. The syntax for
variable expansion is $NAME on all operating systems.  Due to the
order of evaluation, variables are expanded even inside quoted
strings. If the variable NAME is not set, $NAME expands to the
empty string.

    

    
A directive of the form,

    

    //go:generate -command xxx args...

    

    
specifies, for the remainder of this source file only, that the
string xxx represents the command identified by the arguments. This
can be used to create aliases or to handle multiword generators.
For example,

    

    //go:generate -command foo go tool foo

    

    
specifies that the command "foo" represents the generator
"go tool foo".

    

    
Generate processes packages in the order given on the command line,
one at a time. If the command line lists .go files, they are treated
as a single package. Within a package, generate processes the
source files in a package in file name order, one at a time. Within
a source file, generate runs generators in the order they appear
in the file, one at a time.

    

    
If any generator returns an error exit status, "go generate" skips
all further processing for that package.

    

    
The generator is run in the package's source directory.

    

    
Go generate accepts one specific flag:

    

    -run=""
	if non-empty, specifies a regular expression to select
	directives whose full original source text (excluding
	any trailing spaces and final newline) matches the
	expression.

    

    
It also accepts the standard build flags including -v, -n, and -x.
The -v flag prints the names of packages and files as they are
processed.
The -n flag prints commands that would be executed.
The -x flag prints commands as they are executed.

    

    
For more about build flags, see 'go help build'.

    

    
For more about specifying packages, see 'go help packages'.

    

    Download and install packages and dependencies
    

    
Usage:

    

    go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]

    

    
Get downloads the packages named by the import paths, along with their
dependencies. It then installs the named packages, like 'go install'.

    

    
The -d flag instructs get to stop after downloading the packages; that is,
it instructs get not to install the packages.

    

    
The -f flag, valid only when -u is set, forces get -u not to verify that
each package has been checked out from the source control repository
implied by its import path. This can be useful if the source is a local fork
of the original.

    

    
The -fix flag instructs get to run the fix tool on the downloaded packages
before resolving dependencies or building the code.

    

    
The -insecure flag permits fetching from repositories and resolving
custom domains using insecure schemes such as HTTP. Use with caution.

    

    
The -t flag instructs get to also download the packages required to build
the tests for the specified packages.

    

    
The -u flag instructs get to use the network to update the named packages
and their dependencies.  By default, get uses the network to check out
missing packages but does not use it to look for updates to existing packages.

    

    
The -v flag enables verbose progress and debug output.

    

    
Get also accepts build flags to control the installation. See 'go help build'.

    

    
When checking out a new package, get creates the target directory
GOPATH/src/<import-path>. If the GOPATH contains multiple entries,
get uses the first one. For more details see: 'go help gopath'.

    

    
When checking out or updating a package, get looks for a branch or tag
that matches the locally installed version of Go. The most important
rule is that if the local installation is running version "go1", get
searches for a branch or tag named "go1". If no such version exists it
retrieves the most recent version of the package.

    

    
When go get checks out or updates a Git repository,
it also updates any git submodules referenced by the repository.

    

    
Get never checks out or updates code stored in vendor directories.

For more about how 'go get' finds source code to
download, see 'go help importpath'.

    Compile and install packages and dependencies
    

    
Usage:

    

    go install [build flags] [packages]

    

    
Install compiles and installs the packages named by the import paths,
along with their dependencies.

    

    
For more about the build flags, see 'go help build'.
For more about specifying packages, see 'go help packages'.

    

    
See also: go build, go get, go clean.

    

    List packages
    

    
Usage:

    

    go list [-e] [-f format] [-json] [build flags] [packages]

    

    
List lists the packages named by the import paths, one per line.

    

    
The default output shows the package import path:

    

    bytes
encoding/json
github.com/gorilla/mux
golang.org/x/net/html

    

    
The -f flag specifies an alternate format for the list, using the
syntax of package template.  The default output is equivalent to -f
''. The struct being passed to the template is:

    

    type Package struct {
    Dir           string // directory containing package sources
    ImportPath    string // import path of package in dir
    ImportComment string // path in import comment on package statement
    Name          string // package name
    Doc           string // package documentation string
    Target        string // install path
    Shlib         string // the shared library that contains this package (only set when -linkshared)
    Goroot        bool   // is this package in the Go root?
    Standard      bool   // is this package part of the standard Go library?
    Stale         bool   // would 'go install' do anything for this package?
    StaleReason   string // explanation for Stale==true
    Root          string // Go root or Go path dir containing this package
    ConflictDir   string // this directory shadows Dir in $GOPATH
    BinaryOnly    bool   // binary-only package: cannot be recompiled from sources

    // Source files
    GoFiles        []string // .go source files (excluding CgoFiles, TestGoFiles, XTestGoFiles)
    CgoFiles       []string // .go sources files that import "C"
    IgnoredGoFiles []string // .go sources ignored due to build constraints
    CFiles         []string // .c source files
    CXXFiles       []string // .cc, .cxx and .cpp source files
    MFiles         []string // .m source files
    HFiles         []string // .h, .hh, .hpp and .hxx source files
    FFiles         []string // .f, .F, .for and .f90 Fortran source files
    SFiles         []string // .s source files
    SwigFiles      []string // .swig files
    SwigCXXFiles   []string // .swigcxx files
    SysoFiles      []string // .syso object files to add to archive
    TestGoFiles    []string // _test.go files in package
    XTestGoFiles   []string // _test.go files outside package

    // Cgo directives
    CgoCFLAGS    []string // cgo: flags for C compiler
    CgoCPPFLAGS  []string // cgo: flags for C preprocessor
    CgoCXXFLAGS  []string // cgo: flags for C++ compiler
    CgoFFLAGS    []string // cgo: flags for Fortran compiler
    CgoLDFLAGS   []string // cgo: flags for linker
    CgoPkgConfig []string // cgo: pkg-config names

    // Dependency information
    Imports      []string // import paths used by this package
    Deps         []string // all (recursively) imported dependencies
    TestImports  []string // imports from TestGoFiles
    XTestImports []string // imports from XTestGoFiles

    // Error information
    Incomplete bool            // this package or a dependency has an error
    Error      *PackageError   // error loading package
    DepsErrors []*PackageError // errors loading dependencies
}

    

    
Packages stored in vendor directories report an ImportPath that includes the
path to the vendor directory (for example, "d/vendor/p" instead of "p"),
so that the ImportPath uniquely identifies a given copy of a package.
The Imports, Deps, TestImports, and XTestImports lists also contain these
expanded imports paths. See golang.org/s/go15vendor for more about vendoring.

    

    
The error information, if any, is

    

    type PackageError struct {
    ImportStack   []string // shortest path from package named on command line to this one
    Pos           string   // position of error (if present, file:line:col)
    Err           string   // the error itself
}

    

    
The template function "join" calls strings.Join.

    

    
The template function "context" returns the build context, defined as:

    

    type Context struct {
	GOARCH        string   // target architecture
	GOOS          string   // target operating system
	GOROOT        string   // Go root
	GOPATH        string   // Go path
	CgoEnabled    bool     // whether cgo can be used
	UseAllFiles   bool     // use files regardless of +build lines, file names
	Compiler      string   // compiler to assume when computing target paths
	BuildTags     []string // build constraints to match in +build lines
	ReleaseTags   []string // releases the current release is compatible with
	InstallSuffix string   // suffix to use in the name of the install dir
}

    

    
For more information about the meaning of these fields see the documentation
for the go/build package's Context type.

    

    
The -json flag causes the package data to be printed in JSON format
instead of using the template format.

    

    
The -e flag changes the handling of erroneous packages, those that
cannot be found or are malformed.  By default, the list command
prints an error to standard error for each erroneous package and
omits the packages from consideration during the usual printing.
With the -e flag, the list command never prints errors to standard
error and instead processes the erroneous packages with the usual
printing.  Erroneous packages will have a non-empty ImportPath and
a non-nil Error field; other information may or may not be missing
(zeroed).

    

    
For more about build flags, see 'go help build'.

    

    
For more about specifying packages, see 'go help packages'.

    

    Compile and run Go program
    

    
Usage:

    

    go run [build flags] [-exec xprog] gofiles... [arguments...]

    

    
Run compiles and runs the main package comprising the named Go source files.
A Go source file is defined to be a file ending in a literal ".go" suffix.

    

    
By default, 'go run' runs the compiled binary directly: 'a.out arguments...'.
If the -exec flag is given, 'go run' invokes the binary using xprog:

    

    'xprog a.out arguments...'.

    

    
If the -exec flag is not given, GOOS or GOARCH is different from the system
default, and a program named go_$GOOS_$GOARCH_exec can be found
on the current search path, 'go run' invokes the binary using that program,
for example 'go_nacl_386_exec a.out arguments...'. This allows execution of
cross-compiled programs when a simulator or other execution method is
available.

    

    
For more about build flags, see 'go help build'.

    

    
See also: go build.

    

    Test packages
    

    
Usage:

    

    go test [build/test flags] [packages] [build/test flags & test binary flags]

    

    
'Go test' automates testing the packages named by the import paths.
It prints a summary of the test results in the format:

    

    ok   archive/tar   0.011s
FAIL archive/zip   0.022s
ok   compress/gzip 0.033s
...

    

    
followed by detailed output for each failed package.

    

    
'Go test' recompiles each package along with any files with names matching
the file pattern "*_test.go".
Files whose names begin with "_" (including "_test.go") or "." are ignored.
These additional files can contain test functions, benchmark functions, and
example functions.  See 'go help testfunc' for more.
Each listed package causes the execution of a separate test binary.

    

    
Test files that declare a package with the suffix "_test" will be compiled as a
separate package, and then linked and run with the main test binary.

    

    
The go tool will ignore a directory named "testdata", making it available
to hold ancillary data needed by the tests.

    

    
By default, go test needs no arguments.  It compiles and tests the package
with source in the current directory, including tests, and runs the tests.

    

    
The package is built in a temporary directory so it does not interfere with the
non-test installation.

    

    
In addition to the build flags, the flags handled by 'go test' itself are:

    

    -args
    Pass the remainder of the command line (everything after -args)
    to the test binary, uninterpreted and unchanged.
    Because this flag consumes the remainder of the command line,
    the package list (if present) must appear before this flag.

-c
    Compile the test binary to pkg.test but do not run it
    (where pkg is the last element of the package's import path).
    The file name can be changed with the -o flag.

-exec xprog
    Run the test binary using xprog. The behavior is the same as
    in 'go run'. See 'go help run' for details.

-i
    Install packages that are dependencies of the test.
    Do not run the test.

-o file
    Compile the test binary to the named file.
    The test still runs (unless -c or -i is specified).

    

    
The test binary also accepts flags that control execution of the test; these
flags are also accessible by 'go test'. See 'go help testflag' for details.

For more about specifying packages, see 'go help packages'.

    

    
See also: go build, go vet.

    

    Run specified go tool
    

    
Usage:

    

    go tool [-n] command [args...]

    

    
Tool runs the go tool command identified by the arguments.
With no arguments it prints the list of known tools.

    

    
The -n flag causes tool to print the command that would be
executed but not execute it.

    

    
For more about each tool command, see 'go tool command -h'.

    

    Print Go version
    

    
Usage:

    

    go version

    

    
Version prints the Go version, as reported by runtime.Version.

    

    Run go tool vet on packages
    

    
Usage:

    

    go vet [-n] [-x] [build flags] [packages]

    

    
Vet runs the Go vet command on the packages named by the import paths.

    

    
For more about vet, see 'go doc cmd/vet'.
For more about specifying packages, see 'go help packages'.

    

    
To run the vet tool with specific options, run 'go tool vet'.

    

    
The -n flag prints commands that would be executed.
The -x flag prints commands as they are executed.

    

    
For more about build flags, see 'go help build'.

    Calling between Go and C
    

    
There are two different ways to call between Go and C/C++ code.

    

    
The first is the cgo tool, which is part of the Go distribution.  For
information on how to use it see the cgo documentation (go doc cmd/cgo).

    

    
The second is the SWIG program, which is a general tool for
interfacing between languages.  For information on SWIG see
http://swig.org/.  When running go build, any file with a .swig
extension will be passed to SWIG.  Any file with a .swigcxx extension
will be passed to SWIG with the -c++ option.

    

    
When either cgo or SWIG is used, go build will pass any .c, .m, .s,
or .S files to the C compiler, and any .cc, .cpp, .cxx files to the C++
compiler.  The CC or CXX environment variables may be set to determine
the C or C++ compiler, respectively, to use.

    

    Description of build modes
    

    
The 'go build' and 'go install' commands take a -buildmode argument which
indicates which kind of object file is to be built. Currently supported values
are:

    

    -buildmode=archive
	Build the listed non-main packages into .a files. Packages named
	main are ignored.

-buildmode=c-archive
	Build the listed main package, plus all packages it imports,
	into a C archive file. The only callable symbols will be those
	functions exported using a cgo //export comment. Requires
	exactly one main package to be listed.

-buildmode=c-shared
	Build the listed main packages, plus all packages that they
	import, into C shared libraries. The only callable symbols will
	be those functions exported using a cgo //export comment.
	Non-main packages are ignored.

-buildmode=default
	Listed main packages are built into executables and listed
	non-main packages are built into .a files (the default
	behavior).

-buildmode=shared
	Combine all the listed non-main packages into a single shared
	library that will be used when building with the -linkshared
	option. Packages named main are ignored.

-buildmode=exe
	Build the listed main packages and everything they import into
	executables. Packages not named main are ignored.

-buildmode=pie
	Build the listed main packages and everything they import into
	position independent executables (PIE). Packages not named
	main are ignored.

-buildmode=plugin
	Build the listed main packages, plus all packages that they
	import, into a Go plugin. Packages not named main are ignored.

    

    File types
    

    
The go command examines the contents of a restricted set of files
in each directory. It identifies which files to examine based on
the extension of the file name. These extensions are:

    

    .go
	Go source files.
.c, .h
	C source files.
	If the package uses cgo or SWIG, these will be compiled with the
	OS-native compiler (typically gcc); otherwise they will
	trigger an error.
.cc, .cpp, .cxx, .hh, .hpp, .hxx
	C++ source files. Only useful with cgo or SWIG, and always
	compiled with the OS-native compiler.
.m
	Objective-C source files. Only useful with cgo, and always
	compiled with the OS-native compiler.
.s, .S
	Assembler source files.
	If the package uses cgo or SWIG, these will be assembled with the
	OS-native assembler (typically gcc (sic)); otherwise they
	will be assembled with the Go assembler.
.swig, .swigcxx
	SWIG definition files.
.syso
	System object files.

    

    
Files of each of these types except .syso may contain build
constraints, but the go command stops scanning for build constraints
at the first item in the file that is not a blank line or //-style
line comment. See the go/build package documentation for
more details.

    

    
Non-test Go source files can also include a //go:binary-only-package
comment, indicating that the package sources are included
for documentation only and must not be used to build the
package binary. This enables distribution of Go packages in
their compiled form alone. See the go/build package documentation
for more details.

    

    GOPATH environment variable
    

    
The Go path is used to resolve import statements.
It is implemented by and documented in the go/build package.

    

    
The GOPATH environment variable lists places to look for Go code.
On Unix, the value is a colon-separated string.
On Windows, the value is a semicolon-separated string.
On Plan 9, the value is a list.

    

    
If the environment variable is unset, GOPATH defaults
to a subdirectory named "go" in the user's home directory
($HOME/go on Unix, %USERPROFILE%\go on Windows),
unless that directory holds a Go distribution.
Run "go env GOPATH" to see the current GOPATH.

    

    
See https://golang.org/wiki/SettingGOPATH to set a custom GOPATH.

    

    
Each directory listed in GOPATH must have a prescribed structure:

    

    
The src directory holds source code.  The path below src
determines the import path or executable name.

    

    
The pkg directory holds installed package objects.
As in the Go tree, each target operating system and
architecture pair has its own subdirectory of pkg
(pkg/GOOS_GOARCH).

    

    
If DIR is a directory listed in the GOPATH, a package with
source in DIR/src/foo/bar can be imported as "foo/bar" and
has its compiled form installed to "DIR/pkg/GOOS_GOARCH/foo/bar.a".

    

    
The bin directory holds compiled commands.
Each command is named for its source directory, but only
the final element, not the entire path.  That is, the
command with source in DIR/src/foo/quux is installed into
DIR/bin/quux, not DIR/bin/foo/quux.  The "foo/" prefix is stripped
so that you can add DIR/bin to your PATH to get at the
installed commands.  If the GOBIN environment variable is
set, commands are installed to the directory it names instead
of DIR/bin. GOBIN must be an absolute path.

    

    
Here's an example directory layout:

    

    GOPATH=/home/user/go

/home/user/go/
    src/
        foo/
            bar/               (go code in package bar)
                x.go
            quux/              (go code in package main)
                y.go
    bin/
        quux                   (installed command)
    pkg/
        linux_amd64/
            foo/
                bar.a          (installed package object)

    

    
Go searches each directory listed in GOPATH to find source code,
but new packages are always downloaded into the first directory
in the list.

    

    
See https://golang.org/doc/code.html for an example.

    

    Internal Directories
    

    
Code in or below a directory named "internal" is importable only
by code in the directory tree rooted at the parent of "internal".
Here's an extended version of the directory layout above:

    

    /home/user/go/
    src/
        crash/
            bang/              (go code in package bang)
                b.go
        foo/                   (go code in package foo)
            f.go
            bar/               (go code in package bar)
                x.go
            internal/
                baz/           (go code in package baz)
                    z.go
            quux/              (go code in package main)
                y.go

    

    
The code in z.go is imported as "foo/internal/baz", but that
import statement can only appear in source files in the subtree
rooted at foo. The source files foo/f.go, foo/bar/x.go, and
foo/quux/y.go can all import "foo/internal/baz", but the source file
crash/bang/b.go cannot.

    

    
See https://golang.org/s/go14internal for details.

    

    Vendor Directories
    

    
Go 1.6 includes support for using local copies of external dependencies
to satisfy imports of those dependencies, often referred to as vendoring.

    

    
Code below a directory named "vendor" is importable only
by code in the directory tree rooted at the parent of "vendor",
and only using an import path that omits the prefix up to and
including the vendor element.

    

    
Here's the example from the previous section,
but with the "internal" directory renamed to "vendor"
and a new foo/vendor/crash/bang directory added:

    

    /home/user/go/
    src/
        crash/
            bang/              (go code in package bang)
                b.go
        foo/                   (go code in package foo)
            f.go
            bar/               (go code in package bar)
                x.go
            vendor/
                crash/
                    bang/      (go code in package bang)
                        b.go
                baz/           (go code in package baz)
                    z.go
            quux/              (go code in package main)
                y.go

    

    
The same visibility rules apply as for internal, but the code
in z.go is imported as "baz", not as "foo/vendor/baz".

    

    
Code in vendor directories deeper in the source tree shadows
code in higher directories. Within the subtree rooted at foo, an import
of "crash/bang" resolves to "foo/vendor/crash/bang", not the
top-level "crash/bang".

    

    
Code in vendor directories is not subject to import path
checking (see 'go help importpath').

    

    
When 'go get' checks out or updates a git repository, it now also
updates submodules.

    

    
Vendor directories do not affect the placement of new repositories
being checked out for the first time by 'go get': those are always
placed in the main GOPATH, never in a vendor subtree.

    

    
See https://golang.org/s/go15vendor for details.

    

    Environment variables
    

    
The go command, and the tools it invokes, examine a few different
environment variables. For many of these, you can see the default
value of on your system by running 'go env NAME', where NAME is the
name of the variable.

    Import path syntax
    

    
An import path (see 'go help packages') denotes a package stored in the local
file system.  In general, an import path denotes either a standard package (such
as "unicode/utf8") or a package found in one of the work spaces (For more
details see: 'go help gopath').

    

    Relative import paths
    

    
An import path beginning with ./ or ../ is called a relative path.
The toolchain supports relative import paths as a shortcut in two ways.

    

    
First, a relative path can be used as a shorthand on the command line.
If you are working in the directory containing the code imported as
"unicode" and want to run the tests for "unicode/utf8", you can type
"go test ./utf8" instead of needing to specify the full path.
Similarly, in the reverse situation, "go test .." will test "unicode" from
the "unicode/utf8" directory. Relative patterns are also allowed, like
"go test ./..." to test all subdirectories. See 'go help packages' for details
on the pattern syntax.

    

    
Second, if you are compiling a Go program not in a work space,
you can use a relative path in an import statement in that program
to refer to nearby code also not in a work space.
This makes it easy to experiment with small multipackage programs
outside of the usual work spaces, but such programs cannot be
installed with "go install" (there is no work space in which to install them),
so they are rebuilt from scratch each time they are built.
To avoid ambiguity, Go programs cannot use relative import paths
within a work space.

    

    Remote import paths
    

    
Certain import paths also
describe how to obtain the source code for the package using
a revision control system.

    

    
A few common code hosting sites have special syntax:

    

    Bitbucket (Git, Mercurial)

	import "bitbucket.org/user/project"
	import "bitbucket.org/user/project/sub/directory"

GitHub (Git)

	import "github.com/user/project"
	import "github.com/user/project/sub/directory"

Launchpad (Bazaar)

	import "launchpad.net/project"
	import "launchpad.net/project/series"
	import "launchpad.net/project/series/sub/directory"

	import "launchpad.net/~user/project/branch"
	import "launchpad.net/~user/project/branch/sub/directory"

IBM DevOps Services (Git)

	import "hub.jazz.net/git/user/project"
	import "hub.jazz.net/git/user/project/sub/directory"

    

    
For code hosted on other servers, import paths may either be qualified
with the version control type, or the go tool can dynamically fetch
the import path over https/http and discover where the code resides
from a <meta> tag in the HTML.

    

    
To declare the code location, an import path of the form

    

    repository.vcs/path

    

    
specifies the given repository, with or without the .vcs suffix,
using the named version control system, and then the path inside
that repository.  The supported version control systems are:

    

    Bazaar      .bzr
Git         .git
Mercurial   .hg
Subversion  .svn

    

    
For example,

    

    import "example.org/user/foo.hg"

    

    
denotes the root directory of the Mercurial repository at
example.org/user/foo or foo.hg, and

    

    import "example.org/repo.git/foo/bar"

    

    
denotes the foo/bar directory of the Git repository at
example.org/repo or repo.git.

    

    
When a version control system supports multiple protocols,
each is tried in turn when downloading.  For example, a Git
download tries https://, then git+ssh://.

    

    
By default, downloads are restricted to known secure protocols
(e.g. https, ssh). To override this setting for Git downloads, the
GIT_ALLOW_PROTOCOL environment variable can be set (For more details see:
'go help environment').

    

    
If the import path is not a known code hosting site and also lacks a
version control qualifier, the go tool attempts to fetch the import
over https/http and looks for a <meta> tag in the document's HTML
<head>.

    

    
The meta tag has the form:

    

    <meta name="go-import" content="import-prefix vcs repo-root">

    

    
The import-prefix is the import path corresponding to the repository
root. It must be a prefix or an exact match of the package being
fetched with "go get". If it's not an exact match, another http
request is made at the prefix to verify the <meta> tags match.

    

    
The meta tag should appear as early in the file as possible.
In particular, it should appear before any raw JavaScript or CSS,
to avoid confusing the go command's restricted parser.

    

    
The vcs is one of "git", "hg", "svn", etc,

    

    
The repo-root is the root of the version control system
containing a scheme and not containing a .vcs qualifier.

    

    
For example,

    

    import "example.org/pkg/foo"

    

    
will result in the following requests:

    

    https://example.org/pkg/foo?go-get=1 (preferred)
http://example.org/pkg/foo?go-get=1  (fallback, only with -insecure)

    

    
If that page contains the meta tag

    

    <meta name="go-import" content="example.org git https://code.org/r/p/exproj">

    

    
the go tool will verify that https://example.org/?go-get=1 contains the
same meta tag and then git clone https://code.org/r/p/exproj into
GOPATH/src/example.org.

    

    
New downloaded packages are written to the first directory listed in the GOPATH
environment variable (For more details see: 'go help gopath').

    

    
The go command attempts to download the version of the
package appropriate for the Go release being used.
Run 'go help get' for more.

    

    Import path checking
    

    
When the custom import path feature described above redirects to a
known code hosting site, each of the resulting packages has two possible
import paths, using the custom domain or the known hosting site.

    

    
A package statement is said to have an "import comment" if it is immediately
followed (before the next newline) by a comment of one of these two forms:

    

    package math // import "path"
package math /* import "path" */

    

    
The go command will refuse to install a package with an import comment
unless it is being referred to by that import path. In this way, import comments
let package authors make sure the custom import path is used and not a
direct path to the underlying code hosting site.

    

    
Import path checking is disabled for code found within vendor trees.
This makes it possible to copy code into alternate locations in vendor trees
without needing to update import comments.

    

    
See https://golang.org/s/go14customimport for details.

    

    Description of package lists
    

    
Many commands apply to a set of packages:

    

    go action [packages]

    

    
Usually, [packages] is a list of import paths.

    

    
An import path that is a rooted path or that begins with
a . or .. element is interpreted as a file system path and
denotes the package in that directory.

    

    
Otherwise, the import path P denotes the package found in
the directory DIR/src/P for some DIR listed in the GOPATH
environment variable (For more details see: 'go help gopath').

    

    
If no import paths are given, the action applies to the
package in the current directory.

    

    
There are four reserved names for paths that should not be used
for packages to be built with the go tool:

    

    
- "main" denotes the top-level package in a stand-alone executable.

    

    
- "all" expands to all package directories found in all the GOPATH
trees. For example, 'go list all' lists all the packages on the local
system.

    

    
- "std" is like all but expands to just the packages in the standard
Go library.

    

    
- "cmd" expands to the Go repository's commands and their
internal libraries.

    

    
Import paths beginning with "cmd/" only match source code in
the Go repository.

    

    
An import path is a pattern if it includes one or more "..." wildcards,
each of which can match any string, including the empty string and
strings containing slashes.  Such a pattern expands to all package
directories found in the GOPATH trees with names matching the
patterns.  As a special case, x/... matches x as well as x's subdirectories.
For example, net/... expands to net and packages in its subdirectories.

    

    
An import path can also name a package to be downloaded from
a remote repository.  Run 'go help importpath' for details.

    

    
Every package in a program must have a unique import path.
By convention, this is arranged by starting each path with a
unique prefix that belongs to you.  For example, paths used
internally at Google all begin with 'google', and paths
denoting remote repositories begin with the path to the code,
such as 'github.com/user/repo'.

    

    
Packages in a program need not have unique package names,
but there are two reserved package names with special meaning.
The name main indicates a command, not a library.
Commands are built into binaries and cannot be imported.
The name documentation indicates documentation for
a non-Go program in the directory. Files in package documentation
are ignored by the go command.

    

    
As a special case, if the package list is a list of .go files from a
single directory, the command is applied to a single synthesized
package made up of exactly those files, ignoring any build constraints
in those files and ignoring any other files in the directory.

    

    
Directory and file names that begin with "." or "_" are ignored
by the go tool, as are directories named "testdata".

    

    Description of testing flags
    

    
The 'go test' command takes both flags that apply to 'go test' itself
and flags that apply to the resulting test binary.

    

    
Several of the flags control profiling and write an execution profile
suitable for "go tool pprof"; run "go tool pprof -h" for more
information.  The --alloc_space, --alloc_objects, and --show_bytes
options of pprof control how the information is presented.

    

    
The following flags are recognized by the 'go test' command and
control the execution of any test:

    

    -bench regexp
    Run (sub)benchmarks matching a regular expression.
    The given regular expression is split into smaller ones by
    top-level '/', where each must match the corresponding part of a
    benchmark's identifier.
    By default, no benchmarks run. To run all benchmarks,
    use '-bench .' or '-bench=.'.

-benchtime t
    Run enough iterations of each benchmark to take t, specified
    as a time.Duration (for example, -benchtime 1h30s).
    The default is 1 second (1s).

-count n
    Run each test and benchmark n times (default 1).
    If -cpu is set, run n times for each GOMAXPROCS value.
    Examples are always run once.

-cover
    Enable coverage analysis.

-covermode set,count,atomic
    Set the mode for coverage analysis for the package[s]
    being tested. The default is "set" unless -race is enabled,
    in which case it is "atomic".
    The values:
	set: bool: does this statement run?
	count: int: how many times does this statement run?
	atomic: int: count, but correct in multithreaded tests;
		significantly more expensive.
    Sets -cover.

-coverpkg pkg1,pkg2,pkg3
    Apply coverage analysis in each test to the given list of packages.
    The default is for each test to analyze only the package being tested.
    Packages are specified as import paths.
    Sets -cover.

-cpu 1,2,4
    Specify a list of GOMAXPROCS values for which the tests or
    benchmarks should be executed.  The default is the current value
    of GOMAXPROCS.

-parallel n
    Allow parallel execution of test functions that call t.Parallel.
    The value of this flag is the maximum number of tests to run
    simultaneously; by default, it is set to the value of GOMAXPROCS.
    Note that -parallel only applies within a single test binary.
    The 'go test' command may run tests for different packages
    in parallel as well, according to the setting of the -p flag
    (see 'go help build').

-run regexp
    Run only those tests and examples matching the regular expression.
    For tests the regular expression is split into smaller ones by
    top-level '/', where each must match the corresponding part of a
    test's identifier.

-short
    Tell long-running tests to shorten their run time.
    It is off by default but set during all.bash so that installing
    the Go tree can run a sanity check but not spend time running
    exhaustive tests.

-timeout t
    If a test runs longer than t, panic.
    The default is 10 minutes (10m).

-v
    Verbose output: log all tests as they are run. Also print all
    text from Log and Logf calls even if the test succeeds.

    

    
The following flags are also recognized by 'go test' and can be used to
profile the tests during execution:

    

    -benchmem
    Print memory allocation statistics for benchmarks.

-blockprofile block.out
    Write a goroutine blocking profile to the specified file
    when all tests are complete.
    Writes test binary as -c would.

-blockprofilerate n
    Control the detail provided in goroutine blocking profiles by
    calling runtime.SetBlockProfileRate with n.
    See 'go doc runtime.SetBlockProfileRate'.
    The profiler aims to sample, on average, one blocking event every
    n nanoseconds the program spends blocked.  By default,
    if -test.blockprofile is set without this flag, all blocking events
    are recorded, equivalent to -test.blockprofilerate=1.

-coverprofile cover.out
    Write a coverage profile to the file after all tests have passed.
    Sets -cover.

-cpuprofile cpu.out
    Write a CPU profile to the specified file before exiting.
    Writes test binary as -c would.

-memprofile mem.out
    Write a memory profile to the file after all tests have passed.
    Writes test binary as -c would.

-memprofilerate n
    Enable more precise (and expensive) memory profiles by setting
    runtime.MemProfileRate.  See 'go doc runtime.MemProfileRate'.
    To profile all memory allocations, use -test.memprofilerate=1
    and pass --alloc_space flag to the pprof tool.

-mutexprofile mutex.out
    Write a mutex contention profile to the specified file
    when all tests are complete.
    Writes test binary as -c would.

-mutexprofilefraction n
    Sample 1 in n stack traces of goroutines holding a
    contended mutex.

-outputdir directory
    Place output files from profiling in the specified directory,
    by default the directory in which "go test" is running.

-trace trace.out
    Write an execution trace to the specified file before exiting.

    

    
Each of these flags is also recognized with an optional 'test.' prefix,
as in -test.v. When invoking the generated test binary (the result of
'go test -c') directly, however, the prefix is mandatory.

    

    
The 'go test' command rewrites or removes recognized flags,
as appropriate, both before and after the optional package list,
before invoking the test binary.

    

    
For instance, the command

    

    go test -v -myflag testdata -cpuprofile=prof.out -x

    

    
will compile the test binary and then run it as

    

    pkg.test -test.v -myflag testdata -test.cpuprofile=prof.out

    

    
(The -x flag is removed because it applies only to the go command's
execution, not to the test itself.)

    

    
The test flags that generate profiles (other than for coverage) also
leave the test binary in pkg.test for use when analyzing the profiles.

    

    
When 'go test' runs a test binary, it does so from within the
corresponding package's source code directory. Depending on the test,
it may be necessary to do the same when invoking a generated test
binary directly.

    

    
The command-line package list, if present, must appear before any
flag not known to the go test command. Continuing the example above,
the package list would have to appear before -myflag, but could appear
on either side of -v.

    

    
To keep an argument for a test binary from being interpreted as a
known flag or a package name, use -args (see 'go help test') which
passes the remainder of the command line through to the test binary
uninterpreted and unaltered.

    

    
For instance, the command

    

    go test -v -args -x -v

    

    
will compile the test binary and then run it as

    

    pkg.test -test.v -x -v

    

    
Similarly,

    

    go test -args math

    

    
will compile the test binary and then run it as

    

    pkg.test math

    

    
In the first example, the -x and the second -v are passed through to the
test binary unchanged and with no effect on the go command itself.
In the second example, the argument math is passed through to the test
binary, instead of being interpreted as the package list.

    

    Description of testing functions
    

    
The 'go test' command expects to find test, benchmark, and example functions
in the "*_test.go" files corresponding to the package under test.

    

    
A test function is one named TestXXX (where XXX is any alphanumeric string
not starting with a lower case letter) and should have the signature,

    

    func TestXXX(t *testing.T) { ... }

    

    
A benchmark function is one named BenchmarkXXX and should have the signature,

    

    func BenchmarkXXX(b *testing.B) { ... }

    

    
An example function is similar to a test function but, instead of using
*testing.T to report success or failure, prints output to os.Stdout.
If the last comment in the function starts with "Output:" then the output
is compared exactly against the comment (see examples below). If the last
comment begins with "Unordered output:" then the output is compared to the
comment, however the order of the lines is ignored. An example with no such
comment is compiled but not executed. An example with no text after
"Output:" is compiled, executed, and expected to produce no output.

    

    
Godoc displays the body of ExampleXXX to demonstrate the use
of the function, constant, or variable XXX.  An example of a method M with
receiver type T or *T is named ExampleT_M.  There may be multiple examples
for a given function, constant, or variable, distinguished by a trailing _xxx,
where xxx is a suffix not beginning with an upper case letter.

    

    
Here is an example of an example:

    

    func ExamplePrintln() {
	Println("The output of\nthis example.")
	// Output: The output of
	// this example.
}

    

    
Here is another example where the ordering of the output is ignored:

    

    func ExamplePerm() {
	for _, value := range Perm(4) {
		fmt.Println(value)
	}

	// Unordered output: 4
	// 2
	// 1
	// 3
	// 0
}

    

    
The entire test file is presented as the example when it contains a single
example function, at least one other function, type, variable, or constant
declaration, and no test or benchmark functions.

    

    
See the documentation of the testing package for more information.

**h2i** is an interactive HTTP/2 ("h2") console debugger. Miss the good ol'
days of telnetting to your HTTP/1.n servers? We're bringing you
back.

Features:
- send raw HTTP/2 frames
 - PING
 - SETTINGS
 - HEADERS
 - etc
- type in HTTP/1.n and have it auto-HPACK/frame-ify it for HTTP/2
- pretty print all received HTTP/2 frames from the peer (including HPACK decoding)
- tab completion of commands, options

Not yet features, but soon:
- unnecessary CONTINUATION frames on short boundaries, to test peer implementations 
- request bodies (DATA frames)
- send invalid frames for testing server implementations (supported by underlying Framer)

Later:
- act like a server

// TODO: turn off the serve goroutine when idle, so
// an idle conn only has the readFrames goroutine active. (which could
// also be optimized probably to pin less memory in crypto/tls). This
// would involve tracking when the serve goroutine is active (atomic
// int32 read/CAS probably?) and starting it up when frames arrive,
// and shutting it down when all handlers exit. the occasional PING
// packets could use time.AfterFunc to call sc.wakeStartServeLoop()
// (which is a no-op if already running) and then queue the PING write
// as normal. The serve loop would then exit in most cases (if no
// Handlers running) and not be woken up again until the PING packet
// returns.

// TODO (maybe): add a mechanism for Handlers to going into
// half-closed-local mode (rw.(io.Closer) test?) but not exit their
// handler, and continue to be able to read from the
// Request.Body. This would be a somewhat semantic change from HTTP/1
// (or at least what we expose in net/http), so I'd probably want to
// add it there too. For now, this package says that returning from
// the Handler ServeHTTP function means you're both done reading and
// done writing, without a way to stop just one or the other.

// predeclarnig them. So: change of plans. We still permit the old

package idna

// This file contains definitions for interpreting the trie value of the idna
// trie generated by "go run gen*.go". It is shared by both the generator
// program and the resultant package. Sharing is achieved by the generator
// copying gen_trieval.go to trieval.go and changing what's above this comment.

// info holds information from the IDNA mapping table for a single rune. It is
// the value returned by a trie lookup. In most cases, all information fits in
// a 16-bit value. For mappings, this value may contain an index into a slice
// with the mapped string. Such mappings can consist of the actual mapped value
// or an XOR pattern to be applied to the bytes of the UTF8 encoding of the
// input rune. This technique is used by the cases packages and reduces the
// table size significantly.
//
// The per-rune values have the following format:
//
//   if mapped {
//     if inlinedXOR {
//       15..13 inline XOR marker
//       12..11 unused
//       10..3  inline XOR mask

// Package ipv4 implements IP-level socket options for the Internet
// Protocol version 4.
//
// The package provides IP-level socket options that allow

//
// The IPv4 protocol and basic host requirements for IPv4 are defined

// 3376.
// Source-specific multicast is defined in RFC 4607.
//
//
// Unicasting
//
// The options for unicasting are available for net.TCPConn,
// net.UDPConn and net.IPConn which are created as network connections
// that use the IPv4 transport. When a single TCP connection carrying

//
// Note that it depends on each platform implementation what happens
// when an application which runs on IGMPv3 unsupported platform uses
// JoinSourceSpecificGroup and LeaveSourceSpecificGroup.
// In general the platform tries to fall back to conversations using
// IGMPv1 or IGMPv2 and starts to listen to multicast traffic.
// In the fallback case, ExcludeSourceSpecificGroup and
// IncludeSourceSpecificGroup may return an error.

// Package ipv6 implements IP-level socket options for the Internet
// Protocol version 6.
//
// The package provides IP-level socket options that allow
// manipulation of IPv6 facilities.
//
// The IPv6 protocol is defined in RFC 8200.
// Socket interface extensions are defined in RFC 3493, RFC 3542 and
// RFC 3678.
// MLDv1 and MLDv2 are defined in RFC 2710 and RFC 3810.
// Source-specific multicast is defined in RFC 4607.
//
// On Darwin, this package requires OS X Mavericks version 10.9 or
// above, or equivalent.
//
//
// Unicasting
//
// The options for unicasting are available for net.TCPConn,
// net.UDPConn and net.IPConn which are created as network connections
// that use the IPv6 transport. When a single TCP connection carrying
// a data flow of multiple packets needs to indicate the flow is
// important, Conn is used to set the traffic class field on the IPv6
// header for each packet.
//
//	ln, err := net.Listen("tcp6", "[::]:1024")

//				// error handling
//			}
//			if _, err := c.Write(data); err != nil {
//				// error handling
//			}
//		}(c)
//	}
//
//
// Multicasting
//
// The options for multicasting are available for net.UDPConn and
// net.IPConn which are created as network connections that use the
// IPv6 transport. A few network facilities must be prepared before
// you begin multicasting, at a minimum joining network interfaces and
// multicast groups.

//
// Second, the application joins multicast groups, starts listening to
// the groups on the specified network interfaces. Note that the

// protocols, such as IPv6 and Ethernet.

// SetControlMessage of PacketConn is used to enable control message
// transmissions.

//			}
//		}
//	}
//
//
// More multicasting
//
// An application that uses PacketConn may join multiple multicast
// groups. For example, a UDP listener with port 1024 might join two
// different groups across over two different network interfaces by
// using:
//
//	c, err := net.ListenPacket("udp6", "[::]:1024")

//	if err := p.JoinGroup(en1, &net.UDPAddr{IP: net.ParseIP("ff02::2:114")}); err != nil {
//		// error handling
//	}
//
// It is possible for multiple UDP listeners that listen on the same
// UDP port to join the same multicast group. The net package will
// provide a socket that listens to a wildcard address with reusable
// UDP port when an appropriate multicast address prefix is passed to
// the net.ListenPacket or net.ListenUDP.
//
//	c1, err := net.ListenPacket("udp6", "[ff02::]:1024")

//	if err := p2.JoinGroup(en0, &net.UDPAddr{IP: net.ParseIP("ff02::114")}); err != nil {
//		// error handling
//	}
//
// Also it is possible for the application to leave or rejoin a
// multicast group on the network interface.
//
//	if err := p.LeaveGroup(en0, &net.UDPAddr{IP: net.ParseIP("ff02::114")}); err != nil {

//
//
// Source-specific multicasting
//
// An application that uses PacketConn on MLDv2 supported platform is
// able to join source-specific multicast groups.
// The application may use JoinSourceSpecificGroup and
// LeaveSourceSpecificGroup for the operation known as "include" mode,
//
//	ssmgroup := net.UDPAddr{IP: net.ParseIP("ff32::8000:9")}

//		// error handling
//	}
//	if err := p.LeaveSourceSpecificGroup(en0, &ssmgroup, &ssmsource); err != nil {
//		// error handling
//	}
//
// or JoinGroup, ExcludeSourceSpecificGroup,
// IncludeSourceSpecificGroup and LeaveGroup for the operation known
// as "exclude" mode.
//
//	exclsource := net.UDPAddr{IP: net.ParseIP("fe80::dead")}
//	if err := p.JoinGroup(en0, &ssmgroup); err != nil {
//		// error handling

//		// error handling
//	}
//	if err := p.LeaveGroup(en0, &ssmgroup); err != nil {
//		// error handling
//	}
//
// Note that it depends on each platform implementation what happens
// when an application which runs on MLDv2 unsupported platform uses
// JoinSourceSpecificGroup and LeaveSourceSpecificGroup.
// In general the platform tries to fall back to conversations using
// MLDv1 and starts to listen to multicast traffic.
// In the fallback case, ExcludeSourceSpecificGroup and
// IncludeSourceSpecificGroup may return an error.

// Package publicsuffix provides a public suffix list based on data from
// https://publicsuffix.org/
//
// A public suffix is one under which Internet users can directly register
// names. It is related to, but different from, a TLD (top level domain).
//
// "com" is a TLD (top level domain). Top level means it has no dots.
//
// "com" is also a public suffix. Amazon and Google have registered different
// siblings under that domain: "amazon.com" and "google.com".
//
// "au" is another TLD, again because it has no dots. But it's not "amazon.au".
// Instead, it's "amazon.com.au".
//
// "com.au" isn't an actual TLD, because it's not at the top level (it has
// dots). But it is an eTLD (effective TLD), because that's the branching point
// for domain name registrars.
//
// Another name for "an eTLD" is "a public suffix". Often, what's more of
// interest is the eTLD+1, or one more label than the public suffix. For
// example, browsers partition read/write access to HTTP cookies according to
// the eTLD+1. Web pages served from "amazon.com.au" can't read cookies from
// "google.com.au", but web pages served from "maps.google.com" can share
// cookies from "www.google.com", so you don't have to sign into Google Maps
// separately from signing into Google Web Search. Note that all four of those
// domains have 3 labels and 2 dots. The first two domains are each an eTLD+1,
// the last two are not (but share the same eTLD+1: "google.com").
//
// All of these domains have the same eTLD+1:
//  - "www.books.amazon.co.uk"
//  - "books.amazon.co.uk"
//  - "amazon.co.uk"
// Specifically, the eTLD+1 is "amazon.co.uk", because the eTLD is "co.uk".
//
// There is no closed form algorithm to calculate the eTLD of a domain.
// Instead, the calculation is data driven. This package provides a
// pre-compiled snapshot of Mozilla's PSL (Public Suffix List) data at
// https://publicsuffix.org/

// nodes is the list of nodes. Each node is represented as a uint32, which
// encodes the node's children, wildcard bit and node type (as an index into
// the children array), ICANN bit and text.
//
// If the table was generated with the -comments flag, there is a //-comment
// after each node's data. In it is the nodes-array indexes of the children,
// formatted as (n0x1234-n0x1256), with * denoting the wildcard bit. The
// nodeType is printed as + for normal, ! for exception, and o for parent-only
// nodes that have children but don't match a domain label in their own right.
// An I denotes an ICANN domain.
//
// The layout within the uint32, from MSB to LSB, is:
//	[ 0 bits] unused
//	[10 bits] children index
//	[ 1 bits] ICANN bit
//	[15 bits] text index
//	[ 6 bits] text length

// base inside the kernel by writing and reading route messages on a
// routing socket.
//

Package trace implements tracing of requests and long-lived objects.
It exports HTTP interfaces on /debug/requests and /debug/events.

A trace.Trace provides tracing for short-lived objects, usually requests.
A request handler might be implemented like this:

	func fooHandler(w http.ResponseWriter, req *http.Request) {
		tr := trace.New("mypkg.Foo", req.URL.Path)
		defer tr.Finish()
		...
		tr.LazyPrintf("some event %q happened", str)
		...
		if err := somethingImportant(); err != nil {
			tr.LazyPrintf("somethingImportant failed: %v", err)
			tr.SetError()
		}
	}

The /debug/requests HTTP endpoint organizes the traces by family,
errors, and duration.  It also provides histogram of request duration
for each family.

A trace.EventLog provides tracing for long-lived objects, such as RPC
connections.

	// A Fetcher fetches URL paths for a single domain.
	type Fetcher struct {
		domain string
		events trace.EventLog
	}

	func NewFetcher(domain string) *Fetcher {
		return &Fetcher{
			domain,
			trace.NewEventLog("mypkg.Fetcher", domain),
		}
	}

	func (f *Fetcher) Fetch(path string) (string, error) {
		resp, err := http.Get("http://" + f.domain + "/" + path)
		if err != nil {
			f.events.Errorf("Get(%q) = %v", path, err)
			return "", err
		}
		f.events.Printf("Get(%q) = %s", path, resp.Status)
		...
	}

	func (f *Fetcher) Close() error {
		f.events.Finish()
		return nil
	}

The /debug/events HTTP endpoint organizes the event logs by family and
by time since the last error.  The expanded view displays recent log
entries and the log's call stack.

https://go.googlesource.com/go/+/c0d6d33 "encoding/xml: restore Go 1.4 name
space behavior" made late in the lead-up to the Go 1.5 release.

The list of encoding/xml changes is at

This fork is temporary, and I (nigeltao) expect to revert it after Go 1.6 is
released.

// elements containing the data.
//

//     - the value of the XMLName field of type xml.Name
//     - the tag of the struct field used to obtain the data

// exported fields of the struct, with these exceptions:
//     - the XMLName field, described above, is omitted.
//     - a field with tag "-" is omitted.
//     - a field with tag "name,attr" becomes an attribute with
//       the given name in the XML element.
//     - a field with tag ",attr" becomes an attribute with the
//       field name in the XML element.
//     - a field with tag ",chardata" is written as character data,
//       not as an XML element.
//     - a field with tag ",innerxml" is written verbatim, not subject
//       to the usual marshalling procedure.
//     - a field with tag ",comment" is written as an XML comment, not
//       subject to the usual marshalling procedure. It must not contain
//       the "--" string within it.
//     - a field with a tag including the "omitempty" option is omitted
//       if the field value is empty. The empty values are false, 0, any

//       value were part of the outer struct.
//

// BUG(rsc): Mapping between XML elements and data structures is inherently flawed:
// an XML element is an order-dependent collection of anonymous
// values, while a data structure is an order-independent collection
// of named values.
// See package json for a textual representation more suitable
// to data structures.

// Unmarshal parses the XML-encoded data and stores the result in
// the value pointed to by v, which must be an arbitrary struct,
// slice, or string. Well-formed data that does not fit into v is
// discarded.
//
// Because Unmarshal uses the reflect package, it can only assign
// to exported (upper case) fields. Unmarshal uses a case-sensitive
// comparison to match XML element names to tag values and struct
// field names.
//
// Unmarshal maps an XML element to a struct using the following rules.
// In the rules, the tag of a field refers to the value associated with the
// key 'xml' in the struct field's tag (see the example above).
//
//   * If the struct has a field of type []byte or string with tag
//      ",innerxml", Unmarshal accumulates the raw XML nested inside the
//      element in that field. The rest of the rules still apply.
//
//   * If the struct has a field named XMLName of type xml.Name,
//      Unmarshal records the element name in that field.
//
//   * If the XMLName field has an associated tag of the form
//      "name" or "namespace-URL name", the XML element must have
//      the given name (and, optionally, name space) or else Unmarshal
//      returns an error.
//
//   * If the XML element has an attribute whose name matches a
//      struct field name with an associated tag containing ",attr" or
//      the explicit name in a struct field tag of the form "name,attr",
//      Unmarshal records the attribute value in that field.
//
//   * If the XML element contains character data, that data is
//      accumulated in the first struct field that has tag ",chardata".
//      The struct field may have type []byte or string.
//      If there is no such field, the character data is discarded.
//
//   * If the XML element contains comments, they are accumulated in
//      the first struct field that has tag ",comment".  The struct
//      field may have type []byte or string. If there is no such
//      field, the comments are discarded.
//
//   * If the XML element contains a sub-element whose name matches
//      the prefix of a tag formatted as "a" or "a>b>c", unmarshal
//      will descend into the XML structure looking for elements with the
//      given names, and will map the innermost elements to that struct
//      field. A tag starting with ">" is equivalent to one starting
//      with the field name followed by ">".
//
//   * If the XML element contains a sub-element whose name matches
//      a struct field's XMLName tag and the struct field has no
//      explicit name tag as per the previous rule, unmarshal maps
//      the sub-element to that struct field.
//
//   * If the XML element contains a sub-element whose name matches a
//      field without any mode flags (",attr", ",chardata", etc), Unmarshal
//      maps the sub-element to that struct field.
//
//   * If the XML element contains a sub-element that hasn't matched any
//      of the above rules and the struct has a field with tag ",any",
//      unmarshal maps the sub-element to that struct field.
//
//   * An anonymous struct field is handled as if the fields of its
//      value were part of the outer struct.
//
//   * A struct field with tag "-" is never unmarshalled into.
//
// Unmarshal maps an XML element to a string or []byte by saving the
// concatenation of that element's character data in the string or
// []byte. The saved []byte is never nil.
//
// Unmarshal maps an attribute value to a string or []byte by saving
// the value in the string or slice.
//
// Unmarshal maps an XML element to a slice by extending the length of
// the slice and mapping the element to the newly created value.
//
// Unmarshal maps an XML element or attribute value to a bool by
// setting it to the boolean value represented by the string.
//
// Unmarshal maps an XML element or attribute value to an integer or
// floating-point field by setting the field to the result of
// interpreting the string value in decimal. There is no check for
// overflow.
//
// Unmarshal maps an XML element to an xml.Name by recording the
// element name.
//
// Unmarshal maps an XML element to a pointer by setting the pointer
// to a freshly allocated value and then mapping the element to that value.

Code Review - My issueshttp://codereview.appspot.com/rietveld<>rietveld: an attempt at pubsubhubbub
2009-10-04T01:35:58+00:00email-address-removedurn:md5:134d9179c41f806be79b3a5f7877d19a
  An attempt at adding pubsubhubbub support to Rietveld.
http://code.google.com/p/pubsubhubbub
http://code.google.com/p/rietveld/issues/detail?id=155

The server side of the protocol is trivial:
  1. add a &lt;link rel=&quot;hub&quot; href=&quot;hub-server&quot;&gt; tag to all
     feeds that will be pubsubhubbubbed.
  2. every time one of those feeds changes, tell the hub
     with a simple POST request.

I have tested this by adding debug prints to a local hub
server and checking that the server got the right publish
requests.

I can&#39;t quite get the server to work, but I think the bug
is not in my code.  I think that the server expects to be
able to grab the feed and see the feed&#39;s actual URL in
the link rel=&quot;self&quot;, but the default value for that drops
the :port from the URL, and I cannot for the life of me
figure out how to get the Atom generator deep inside
django not to do that, or even where it is doing that,
or even what code is running to generate the Atom feed.
(I thought I knew but I added some assert False statements
and it kept running!)

Ignoring that particular problem, I would appreciate
feedback on the right way to get the two values at
the top of feeds.py marked NOTE(rsc).


rietveld: correct tab handling
2009-10-03T23:02:17+00:00email-address-removedurn:md5:0a2a4f19bb815101f0ba2904aed7c35a
  This fixes the buggy tab rendering that can be seen at
http://codereview.appspot.com/116075/diff/1/2

The fundamental problem was that the tab code was
not being told what column the text began in, so it
didn&#39;t know where to put the tab stops.  Another problem
was that some of the code assumed that string byte
offsets were the same as column offsets, which is only
true if there are no tabs.

In the process of fixing this, I cleaned up the arguments
to Fold and ExpandTabs and renamed them Break and
_ExpandTabs so that I could be sure that I found all the
call sites.  I also wanted to verify that ExpandTabs was
not being used from outside intra_region_diff.py.
