After a value in the series is +added to the average, its weight in the average decreases exponentially over time. This +biases the average towards more recent data. EWMAs are useful for several reasons, chiefly +their inexpensive computational and memory cost, as well as the fact that they represent +the recent central tendency of the series of values. + +The EWMA algorithm requires a decay factor, alpha. The larger the alpha, the more the average +is biased towards recent history. The alpha must be between 0 and 1, and is typically +a fairly small number, such as 0.04. We will discuss the choice of alpha later. + +The algorithm works thus, in pseudocode: + +1. Multiply the next number in the series by alpha. +2. Multiply the current value of the average by 1 minus alpha. +3. Add the result of steps 1 and 2, and store it as the new current value of the average. +4. Repeat for each number in the series. + +There are special-case behaviors for how to initialize the current value, and these vary +between implementations. One approach is to start with the first value in the series; +another is to average the first 10 or so values in the series using an arithmetic average, +and then begin the incremental updating of the average. Each method has pros and cons. + +It may help to look at it pictorially. Suppose the series has five numbers, and we choose +alpha to be 0.50 for simplicity. Here's the series, with numbers in the neighborhood of 300. + +![Data Series](https://user-images.githubusercontent.com/279875/28242350-463289a2-6977-11e7-88ca-fd778ccef1f0.png) + +Now let's take the moving average of those numbers.

It is a smoothed, or low-pass, average of the original +series. + +For further reading, see [Exponentially weighted moving average](http://en.wikipedia.org/wiki/Moving_average#Exponential_moving_average) on wikipedia. + +### Choosing Alpha + +Consider a fixed-size sliding-window moving average (not an exponentially weighted moving average) +that averages over the previous N samples. What is the average age of each sample? It is N/2. + +Now suppose that you wish to construct a EWMA whose samples have the same average age. The formula +to compute the alpha required for this is: alpha = 2/(N+1). Proof is in the book +"Production and Operations Analysis" by Steven Nahmias. + +So, for example, if you have a time-series with samples once per second, and you want to get the +moving average over the previous minute, you should use an alpha of .032786885. This, by the way, +is the constant alpha used for this repository's SimpleEWMA. + +### Implementations + +This repository contains two implementations of the EWMA algorithm, with different properties. + +The implementations all conform to the MovingAverage interface, and the constructor returns +that type. + +Current implementations assume an implicit time interval of 1.0 between every sample added. +That is, the passage of time is treated as though it's the same as the arrival of samples. +If you need time-based decay when samples are not arriving precisely at set intervals, then +this package will not support your needs at present. + +#### SimpleEWMA + +A SimpleEWMA is designed for low CPU and memory consumption. It **will** have different behavior than the VariableEWMA +for multiple reasons. It has no warm-up period and it uses a constant +decay. These properties let it use less memory. It will also behave +differently when it's equal to zero, which is assumed to mean +uninitialized, so if a value is likely to actually become zero over time, +then any non-zero value will cause a sharp jump instead of a small change. + +#### VariableEWMA + +Unlike SimpleEWMA, this supports a custom age which must be stored, and thus uses more memory. +It also has a "warmup" time when you start adding values to it. It will report a value of 0.0 +until you have added the required number of samples to it. It uses some memory to store the +number of samples added to it. As a result it uses a little over twice the memory of SimpleEWMA. + +## Usage + +### API Documentation + +View the GoDoc generated documentation [here](http://godoc.org/github.com/VividCortex/ewma). + +```go +package main +import "github.com/VividCortex/ewma" + +func main() { + samples := [100]float64{ + 4599, 5711, 4746, 4621, 5037, 4218, 4925, 4281, 5207, 5203, 5594, 5149, + } + + e := ewma.NewMovingAverage() //=> Returns a SimpleEWMA if called without params + a := ewma.NewMovingAverage(5) //=> returns a VariableEWMA with a decay of 2 / (5 + 1) + + for _, f := range samples { + e.Add(f) + a.Add(f) + } + + e.Value() //=> 13.577404704631077 + a.Value() //=> 1.5806140565521463e-12 +} +``` + +## Contributing + +We only accept pull requests for minor fixes or improvements.

Read our [blog post](https://vividcortex.com/blog/2013/08/27/godaemon-a-library-to-daemonize-go-apps/) on the subject. + +You can't daemonize the usual way in Go. Daemonizing is a Unix concept that requires +some [specific things](http://goo.gl/vTUsVy) you can't do +easily in Go. But you can still accomplish the same goals +if you don't mind that your program will start copies of itself +several times, as opposed to using `fork()` the way many programmers are accustomed to doing. + +It is somewhat controversial whether it's even a good idea to make programs daemonize themselves, +or how to do it correctly (and whether it's even possible to do correctly in Go). +Read [here](https://code.google.com/p/go/issues/detail?id=227), +[here](http://www.ryanday.net/2012/09/04/the-problem-with-a-golang-daemon/), +and [here](http://stackoverflow.com/questions/14537045/how-i-should-run-my-golang-process-in-background) +for more on this topic. However, at [VividCortex](https://vividcortex.com/) we do need to run one of our processes as a +daemon with the usual attributes of a daemon, and we chose the approach implemented in this package. + +Because of the factors mentioned in the first link just given, you should take great care when +using this package's approach. It works for us, because we don't do anything like starting up +goroutines in our `init()` functions, or other things that are perfectly legal in Go in general. + +## Getting Started + +View the [package documentation](http://godoc.org/github.com/VividCortex/godaemon) +for details about how it works. Briefly, to make your program into a daemon, +do the following as soon as possible in your `main()` function: + +```go +import ( + "github.com/VividCortex/godaemon" +) + +func main() { + godaemon.MakeDaemon(&godaemon.DaemonAttr{}) +} +``` + +Use the `CaptureOutput` attribute if you need to capture your program's +standard output and standard error streams. In that case, the function returns +two valid readers (`io.Reader`) that you can read from the program itself. +That's particularly useful for functions that write error or diagnosis messages +right to the error output, which are normally lost in a daemon. + +Use the `Files` attribute if you need to inherit open files into the daemon. +This is primarily intended for avoiding race conditions when holding locks on +those files (flocks). Releasing and re-acquiring locks between successive fork +calls opens up the chance for another program to steal the lock. However, by +declaring your file descriptors in the `Files` attribute, `MakeDaemon()` will +guarantee that locks are not released throughout the whole process. Your daemon +will inherit the file still holding the same locks, with no other process having +intervened in between. See the +[package documentation](http://godoc.org/github.com/VividCortex/godaemon) for +more details and sample code. (Note that you shouldn't use this feature to +inherit TTY descriptors; otherwise what you get is technically not a daemon.) + + +## Contribute + +Contributions are welcome.

But given the lack of Go's +support for fork(), MakeDaemon() is forced to run the process all over again, +from the start. Hence, this should probably be your first call after main +begins, unless you understand the effects of calling from somewhere else. +Keep in mind that the PID changes after this function is called, given +that it only returns in the child; the parent will exit without returning. + +Options are provided as a DaemonAttr structure. In particular, setting the +CaptureOutput member to true will make the function return two io.Reader +streams to read the process' standard output and standard error, respectively. +That's useful if you want to capture things you'd normally lose given the +lack of console output for a daemon. Some libraries can write error conditions +to standard error or make use of Go's log package, that defaults to standard +error too. Having these streams allows you to capture them as required. (Note +that this function takes no action whatsoever on any of the streams.) + +NOTE: If you use them, make sure NOT to take one of these readers and write +the data back again to standard output/error, or you'll end up with a loop. +Also, note that data will be flushed on a line-by-line basis; i.e., partial +lines will be buffered until an end-of-line is seen. + +By using the Files member of DaemonAttr you can inherit open files that will +still be open once the program is running as a daemon. This may be convenient in +general, but it's primarily intended to avoid race conditions while forking, in +case a lock (flock) was held on that file. Repeatedly releasing and re-locking +while forking is subject to race conditions, cause a different process could +lock the file in between. But locks held on files declared at DaemonAttr.Files +are guaranteed NOT to be released during the whole process, and still be held by +the daemon. To use this feature you should open the file(s), lock if required +and then call MakeDaemon using pointers to that *os.File objects; i.e., you'd be +passing **os.File objects to MakeDaemon(). However, opening the files (and +locking if required) should only be attempted at the parent. (Recall that +MakeDaemon() will run the code coming "before" it three times; see the +explanation above.) You can filter that by calling Stage() and looking for a +godaemon.StageParent result. The last call to MakeDaemon() at the daemon itself +will actually *load* the *os.File objects for you; that's why you need to +provide a pointer to them.

You can operate on f as you + // normally would, like: + f.Close() + +NOTE: Do not abuse this feature. Even though you could, it's obviously not a +good idea to use this mechanism to keep a terminal device open, for instance. +Otherwise, what you get is not strictly a daemon. + + +Daemonizing is a 3-stage process. In stage 0, the program increments the +magical environment variable and starts a copy of itself that's a session +leader, with its STDIN, STDOUT, and STDERR disconnected from any tty. It +then exits. + +In stage 1, the (new copy of) the program starts another copy that's not +a session leader, and then exits. + +In stage 2, the (new copy of) the program chdir's to /, then sets the umask +and reestablishes the original value for the environment variable. +*/ +func MakeDaemon(attrs *DaemonAttr) (io.Reader, io.Reader, error) { + stage, advanceStage, resetEnv := getStage() + + // This is a handy wrapper to do the proper thing in case of fatal + // conditions.

Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + a. such Covered Software must also be made available in Source Code Form, + as described in Section 3.1, and You must inform recipients of the + Executable Form how they can obtain a copy of such Source Code Form by + reasonable means in a timely manner, at a charge no more than the cost + of distribution to the recipient; and + + b. You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter the + recipients' rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for + the Covered Software. If the Larger Work is a combination of Covered + Software with a work governed by one or more Secondary Licenses, and the + Covered Software is not Incompatible With Secondary Licenses, this + License permits You to additionally distribute such Covered Software + under the terms of such Secondary License(s), so that the recipient of + the Larger Work may, at their option, further distribute the Covered + Software under the terms of either this License or such Secondary + License(s). + +3.4.

Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on + behalf of any Contributor. You must make it absolutely clear that any + such warranty, support, indemnity, or liability obligation is offered by + You alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + +4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, + judicial order, or regulation then You must: (a) comply with the terms of + this License to the maximum extent possible; and (b) describe the + limitations and the code they affect.

Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts + of a jurisdiction where the defendant maintains its principal place of + business and such litigation shall be governed by laws of that + jurisdiction, without reference to its conflict-of-law provisions. Nothing + in this Section shall prevent a party's ability to bring cross-claims or + counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject + matter hereof. If any provision of this License is held to be + unenforceable, such provision shall be reformed only to the extent + necessary to make it enforceable. Any law or regulation which provides that + the language of a contract shall be construed against the drafter shall not + be used to construe this License against a Contributor. + + +10. Versions of the License + +10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + +10.2. Effect of New Versions + + You may distribute the Covered Software under the terms of the version + of the License under which You originally received the Covered Software, + or under the terms of any subsequent version published by the license + steward. + +10.3. Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a + modified version of this License if you rename the license and remove + any references to the name of the license steward (except to note that + such modified license differs from this License). + +10.4.

The package +API follows the less-is-more principle, by presenting a small, clean interface. + +The package dns supports (asynchronous) querying/replying, incoming/outgoing zone transfers, +TSIG, EDNS0, dynamic updates, notifies and DNSSEC validation/signing. +Note that domain names MUST be fully qualified, before sending them, unqualified +names in a message will result in a packing failure. + +Resource records are native types.

Use pattern for creating a message: + + m := new(dns.Msg) + m.SetQuestion("miek.nl.", dns.TypeMX) + +Or when not certain if the domain name is fully qualified: + + m.SetQuestion(dns.Fqdn("miek.nl"), dns.TypeMX) + +The message m is now a message with the question section set to ask +the MX records for the miek.nl. zone. + +The following is slightly more verbose, but more flexible: + + m1 := new(dns.Msg) + m1.Id = dns.Id() + m1.RecursionDesired = true + m1.Question = make([]dns.Question, 1) + m1.Question[0] = dns.Question{"miek.nl.", dns.TypeMX, dns.ClassINET} + +After creating a message it can be sent. +Basic use pattern for synchronous querying the DNS at a +server configured on 127.0.0.1 and port 53: + + c := new(dns.Client) + in, rtt, err := c.Exchange(m1, "127.0.0.1:53") + +Suppressing multiple outstanding queries (with the same question, type and +class) is as easy as setting: + + c.SingleInflight = true + +More advanced options are available using a net.Dialer and the corresponding API. +For example it is possible to set a timeout, or to specify a source IP address +and port to use for the connection: + + c := new(dns.Client) + laddr := net.UDPAddr{ + IP: net.ParseIP("[::1]"), + Port: 12345, + Zone: "", + } + d := net.Dialer{ + Timeout: 200 * time.Millisecond, + LocalAddr: &laddr, + } + in, rtt, err := c.ExchangeWithDialer(&d, m1, "8.8.8.8:53") + +If these "advanced" features are not needed, a simple UDP query can be sent, +with: + + in, err := dns.Exchange(m1, "127.0.0.1:53") + +When this functions returns you will get dns message. A dns message consists +out of four sections. +The question section: in.Question, the answer section: in.Answer, +the authority section: in.Ns and the additional section: in.Extra. + +Each of these sections (except the Question section) contain a []RR. Basic +use pattern for accessing the rdata of a TXT RR as the first RR in +the Answer section: + + if t, ok := in.Answer[0].(*dns.TXT); ok { + // do something with t.Txt + } + +Domain Name and TXT Character String Representations + +Both domain names and TXT character strings are converted to presentation +form both when unpacked and when converted to strings. + +For TXT character strings, tabs, carriage returns and line feeds will be +converted to \t, \r and \n respectively. Back slashes and quotations marks +will be escaped. Bytes below 32 and above 127 will be converted to \DDD +form. + +For domain names, in addition to the above rules brackets, periods, +spaces, semicolons and the at symbol are escaped. + +DNSSEC + +DNSSEC (DNS Security Extension) adds a layer of security to the DNS. It +uses public key cryptography to sign resource records. The +public keys are stored in DNSKEY records and the signatures in RRSIG records. + +Requesting DNSSEC information for a zone is done by adding the DO (DNSSEC OK) bit +to a request. + + m := new(dns.Msg) + m.SetEdns0(4096, true) + +Signature generation, signature verification and key generation are all supported. + +DYNAMIC UPDATES + +Dynamic updates reuses the DNS message format, but renames three of +the sections. Question is Zone, Answer is Prerequisite, Authority is +Update, only the Additional is not renamed. See RFC 2136 for the gory details. + +You can set a rather complex set of rules for the existence of absence of +certain resource records or names in a zone to specify if resource records +should be added or removed.

What did you see instead? + +General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker. +The gophers there will answer or ask you to file an issue if you've tripped over a bug. + +## Contributing code + +Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html) +before sending patches. + +**We do not accept GitHub pull requests** +(we use [Gerrit](https://code.google.com/p/gerrit/) instead for code review). + +Unless otherwise noted, the Go source files are distributed under +the BSD-style license found in the LICENSE file. + diff --git a/vendor/golang.org/x/crypto/CONTRIBUTORS b/vendor/golang.org/x/crypto/CONTRIBUTORS new file mode 100644 index 00000000..1fbd3e97 --- /dev/null +++ b/vendor/golang.org/x/crypto/CONTRIBUTORS @@ -0,0 +1,3 @@ +# This source code was written by the Go contributors. +# The master list of contributors is in the main Go distribution, +# visible at https://tip.golang.org/CONTRIBUTORS. diff --git a/vendor/golang.org/x/crypto/LICENSE b/vendor/golang.org/x/crypto/LICENSE new file mode 100644 index 00000000..6a66aea5 --- /dev/null +++ b/vendor/golang.org/x/crypto/LICENSE @@ -0,0 +1,27 @@ +Copyright (c) 2009 The Go Authors.

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" diff --git a/vendor/golang.org/x/net/bpf/instructions.go b/vendor/golang.org/x/net/bpf/instructions.go new file mode 100644 index 00000000..3b4fd089 --- /dev/null +++ b/vendor/golang.org/x/net/bpf/instructions.go @@ -0,0 +1,704 @@ +// Copyright 2016 The Go Authors.
