For\n\/\/ example,\n\/\/\t\tfunc UnitDensity(t unit.Temperature, pressure unit.Pressure) (unit.Density){\n\/\/\t\t\t...\n\/\/\t\t}\n\/\/\t\tfunc main(){\n\/\/\t\t\tt := 300 * unit.Kelvin\n\/\/\t\t\tp := 5 * unit.Bar\n\/\/\t\t\trho := UnitDensity(p, t) \/\/ gives compile-time error\n\/\/\t\t}\n\/\/ gives a compile-time error (temperature type does not match pressure type)\n\/\/ while the corresponding code using float64 runs without error.\n\/\/\t\tfunc Float64Density(temperature, pressure float64) (float64){\n\/\/\t\t\t...\n\/\/\t\t}\n\/\/\t\tfunc main(){\n\/\/\t\t\tt := 300.0 \/\/ degrees kelvin\n\/\/\t\t\tp := 50000.0 \/\/ Pascals\n\/\/\t\t\trho := Float64Density(p, t) \/\/ no error\n\/\/\t\t}\n\/\/ Many types have constants defined representing named SI units (Meter,\n\/\/ Kilogram, etc. ) or SI derived units (Bar, Milligram, etc.). These are\n\/\/ all defined as multiples of the base unit, so, for example, the following\n\/\/ are euqivalent\n\/\/\t\tl := 0.001 * unit.Meter\n\/\/\t\tk := 1 * unit.Millimeter\n\/\/\t\tj := unit.Length(0.001)\n\/\/\n\/\/ 2)\n\/\/ Unit provides the type \"Unit\", meant to represent a general dimensional\n\/\/ value. unit.Unit can be used to help prevent errors of dimensionality\n\/\/ when multiplying or dividing dimensional numbers. This package also\n\/\/ provides the \"Uniter\" interface which is satisfied by any type which can\n\/\/ be converted to a unit. New varibles of type Unit can be created with\n\/\/ the NewUnit function and the Dimensions map. For example, the code\n\/\/\t\tacc := NewUnit(9.81, Dimensions{LengthDim:1, TimeDim: -2})\n\/\/ creates a variable \"acc\" which has a value of 9.81 m\/s^2. Methods of\n\/\/ unit can be used to modify this value, for example:\n\/\/ \t\tacc.Mul(1.0 * unit.Kilogram).Mul(1 * unit.Meter)\n\/\/ To convert the unit back into a typed float64 value, the FromUnit methods\n\/\/ of the unit types should be used. FromUnit will return an error if the\n\/\/ dimensions do not match.\n\/\/ \t\tvar energy unit.Energy\n\/\/\t\terr := (*energy).FromUnit(acc)\n\/\/ Domain-specific problems may need custom dimensions, and for this purpose\n\/\/ NewDimension should be used to help avoid accidental overlap between\n\/\/ packages. For example, results from a blood test may be measured in\n\/\/ \"White blood cells per slide\". In this case, NewDimension should be\n\/\/ used to create a 'WhiteBloodCell' dimension. NewDimension should not be\n\/\/ used, however, to create the unit of 'Slide', because in this case slide\n\/\/ is just a measurement of area. Instead, a constant could be defined.\n\/\/\t\tconst Slide unit.Area = 0.001875 \/\/ m^2\n\/\/\t\tfunc init(){\n\/\/\t\t\tWhiteBloodCellDim := unit.NewDimension()\n\/\/\t\t}\n\/\/\t\ttype WbcPerArea float64\n\/\/\t\tfunc [w WbcPerArea] Unit() *Unit{\n\/\/\t\t\treturn NewUnit(w, Dimensions{WhiteBloodCellDim: 1, LengthDim: -2})\n\/\/\t\t}\n\/\/\t\tfunc main(){\n\/\/\t\t\t\/\/ Add in something about using Unit\n\/\/\t\t}\n\/\/ Please note that Unit cannot catch all errors related to dimensionality.\n\/\/ Different physical ideas are sometimes expressed with the same dimensions\n\/\/ and Unit is incapable of catcing these mismatches. For example, energy and\n\/\/ torque are both expressed as force times distance (Newton-meters in SI),\n\/\/ but it is wrong to say that a torque of 10 N-m == 10 J.\npackage unit\n<|endoftext|>"} {"text":"\/\/ Package bazil is a distributed, weakly connected, asynchronous\n\/\/ filesystem.\npackage main\nSet canonical import path\/\/ Package bazil is a distributed, weakly connected, asynchronous\n\/\/ filesystem.\npackage main \/\/ import \"bazil.org\/bazil\"\n<|endoftext|>"} {"text":"\/\/ To use go-sdiscovery in your project, include the following import:\n\/\/\n\/\/ import \"github.com\/nathan-osman\/go-sdiscovery\"\n\/\/\n\/\/ Usage\n\/\/\n\/\/ All interaction with the library takes place through an instance of Service,\n\/\/ which is created in the following manner:\n\/\/\n\/\/ s := New(ServiceConfig{\n\/\/ PollInterval: 1*time.Minute,\n\/\/ PingInterval: 2*time.Second,\n\/\/ PeerTimeout: 8*time.Second,\n\/\/ Port: 1234,\n\/\/ ID: \"machine01\",\n\/\/ })\n\/\/\n\/\/ At this point, the service will begin sending broadcast and multicast\n\/\/ packets on all appropriate network interfaces and listening for packets from\n\/\/ other peers.

(Some systems will stop\n\/\/ processing the keyboard event at all if you return true\n\/\/ unconditionally, which may result in unwanted behavior like\n\/\/ global task-switching keystrokes not being processed.)\n\/\/ \n\/\/ Note that even given the above, some systems might intercept\n\/\/ some keystrokes (like Alt-F4 on various Unix systems) before\n\/\/ Area will ever see them (and the Area might get an incorrect\n\/\/ KeyEvent in this case, but this is not guaranteed); be wary.\n\/\/ \n\/\/ If a key is pressed that is not supported by Key, ExtKey,\n\/\/ or Modifiers, no KeyEvent will be produced, and package\n\/\/ ui will act as if false was returned for handled.\ntype KeyEvent struct {\n\t\/\/ Key is a byte representing a character pressed\n\t\/\/ in the typewriter section of the keyboard.\n\t\/\/ The value, which is independent of whether the\n\t\/\/ Shift key is held, is a constant with one of the\n\t\/\/ following (case-sensitive) values, drawn according\n\t\/\/ to the key's position on the keyboard.\n\t\/\/ ` 1 2 3 4 5 6 7 8 9 0 - =\n\t\/\/ q w e r t y u i o p [ ] \\\n\t\/\/ a s d f g h j k l ; '\n\t\/\/ z x c v b n m , . \/\n\t\/\/ The actual key entered will be the key at the respective\n\t\/\/ position on the user's keyboard, regardless of the actual\n\t\/\/ layout. (Some keyboards move \\ to either the row above\n\t\/\/ or the row below but in roughly the same spot; this is\n\t\/\/ accounted for. Some keyboards have an additonal key\n\t\/\/ to the left of 'z' or additional keys to the right of '='; these\n\t\/\/ cannot be read.)\n\t\/\/ In addition, Key will contain\n\t\/\/ - ' ' (space) if the spacebar was pressed\n\t\/\/ - '\\t' if Tab was pressed, regardless of Modifiers\n\t\/\/ - '\\n' if the typewriter Enter key was pressed\n\t\/\/ - '\\b' if the typewriter Backspace key was pressed\n\t\/\/ If this value is zero, see ExtKey.\n\tKey\t\t\tbyte\n\n\t\/\/ If Key is zero, ExtKey contains a predeclared identifier\n\t\/\/ naming an extended key. See ExtKey for details.\n\t\/\/ If both Key and ExtKey are zero, a Modifier by itself\n\t\/\/ was pressed. Key and ExtKey will not both be nonzero.\n\tExtKey\t\tExtKey\n\n\tModifiers\t\tModifiers\n\n\t\/\/ If Up is true, the key was released; if not, the key was pressed.\n\t\/\/ There is no guarantee that all pressed keys shall have\n\t\/\/ corresponding release events (for instance, if the user switches\n\t\/\/ programs while holding the key down, then releases the key).\n\t\/\/ Keys that have been held down are reported as multiple\n\t\/\/ key press events.\n\tUp\t\t\tbool\n}\n\n\/\/ ExtKey represents keys that are not in the typewriter section of the keyboard.\ntype ExtKey uintptr\nconst (\n\tEscape ExtKey = iota + 1\n\tInsert\n\tDelete\n\tHome\n\tEnd\n\tPageUp\n\tPageDown\n\tUp\n\tDown\n\tLeft\n\tRight\n\tF1\t\t\t\/\/ F1..F12 are guaranteed to be consecutive\n\tF2\n\tF3\n\tF4\n\tF5\n\tF6\n\tF7\n\tF8\n\tF9\n\tF10\n\tF11\n\tF12\n\tN0\t\t\t\/\/ numpad keys;

\"quality of service\" contracts, to best handle that demand within the constraints of your existing VM\n\/\/ or physical infrastructure (for v1).\n\/\/\n\/\/ Force12 is defined to optimize the use of existing physical and VM resources instantly. VMs cannot be scaled in real time (it takes\n\/\/ several minutes) and new physical machines take even longer. However, containers can be started or stopped at sub second speeds,\n\/\/ allowing your infrastructure to adapt itself in real time to meet system demands.\n\/\/\n\/\/ Force12 is aimed at effectively using the resources you have right now - your existing VMs or physical servers - by using them as\n\/\/ optimally as possible.\n\/\/\n\/\/ The Force12 approach is analogous to the way that a router dynamically optimises the use of a physical network. A router is limited\n\/\/ by the capacity of the lines physically connected to it. Adding additional capacity is a physical process and takes time. Routers\n\/\/ therefore make decisions in real time about which packets will be prioritized on a particular line based on the packet's priority\n\/\/ (defined by a \"quality of service\" contract).\n\/\/\n\/\/ For example, at times of high bandwidth usage a router might prioritize VOIP traffic over web browsing in real time.\n\/\/\n\/\/ Containers allow Force12 to make similar \"instant\" judgements on service prioritisation within your existing infrastructure. Routers\n\/\/ make very simplistic judgments because they have limited time and cpu and they act at a per packet level. Force12 has the capability\n\/\/ of making far more sophisticated judgements, although even fairly simple ones will still provide a significant new service.\n\/\/\n\/\/ This prototype is a bare bones implementation of Force12.io that recognises only 1 demand type:\n\/\/ randomised demand for a priority 1 service. Resources are allocated to meet this demand for priority 1, and spare resource can\n\/\/ be used for a priority 2 service.\n\/\/\n\/\/ These demand type examples have been chosen purely for simplicity of demonstration. In the future more demand types\n\/\/ will be offered\n\/\/\n\/\/ V1 - Force12.io reacts to increased demand by starting\/stopping containers on the slaves already in play.\n\/\/\n\/\/ This version of Force12 starts and stops containers on a Mesos cluser using Marathon as the scheduler\npackage main\n\nimport (\n\t\"bytes\"\n\t\"encoding\/json\"\n\t\"fmt\"\n\t\"log\"\n\t\"math\"\n\t\"net\/http\"\n\t\"os\"\n\t\"time\"\n\n\t\"bitbucket.org\/force12io\/force12-scheduler\/marathon\"\n\t\"bitbucket.org\/force12io\/force12-scheduler\/scheduler\"\n)\n\ntype sendStatePayload struct {\n\tCreatedAt int64 `json:\"createdAt\"`\n\tPriority1Requested int `json:\"priority1Requested\"`\n\tPriority1Running int `json:\"priority1Running\"`\n\tPriority2Running int `json:\"priority2Running\"`\n}\n\nconst const_sleep = 100 \/\/milliseconds\nconst const_stopsleep = 250 \/\/milliseconds pause between stopping and restarting containers\nconst const_p1demandstart int = 5\nconst const_p2demandstart int = 4\nconst const_maxcontainers int = 9\n\ntype Demand struct {\n\tsched scheduler.Scheduler\n\n\tp1demand int \/\/ number of Priority 1 tasks demanded\n\tp2demand int\n\tp1requested int \/\/ indicates how many P1 tasks we've tried to kick off.\n\tp2requested int\n}\n\n\/\/ set returns values that were there (p1, p2)\n\/\/ if provided value is -1 don't update, demand will always be between 0 and const_maxcontainers\nfunc (d *Demand) set(p1, p2 int) (int, int) {\n\t\/\/d.mu.Lock()\n\tp1old := d.p1demand\n\tp2old := d.p2demand\n\tif p2 != -1 {\n\t\td.p2demand = p2\n\t}\n\tif p1 != -1 {\n\t\td.p1demand = p1\n\t}\n\t\/\/d.mu.Unlock()\n\treturn p1old, p2old\n}\n\n\/\/ get returns client, server AEC - Combine this with the set to reduce code\nfunc (d *Demand) get() (int, int) {\n\treturn d.p1demand, d.p2demand\n}\n\n\/\/ handle processes a change in demand\n\/\/ Note that handle will make any judgment on what to do with a demand\n\/\/ change, including potentially nothing.\nfunc (d *Demand) handle() error {\n\tvar err error\n\t\/\/ AEC NOTE THIS FUNCTION NEEDS TO BE HEAVILY REWRITTEN TO HANDLE ECS\n\t\/\/ WHEN WE PORT THAT OVER TO THE SAME STRUCTURE.\n\t\/\/ THe reason is that all the code we wrote to handle stopping before\n\t\/\/ starting etc.. is handled directly by Marathon so that code\n\t\/\/ from the old scheduler needs to go behind the scheduler interface\n\terr = d.sched.StopStartNTasks(os.Getenv(\"CLIENT_TASK\"), os.Getenv(\"CLIENT_FAMILY\"), d.p1demand, d.p1requested)\n\tif err != nil {\n\t\tlog.Printf(\"Failed to start Priority1 tasks. %v\", err)\n\t}\n\td.sched.StopStartNTasks(os.Getenv(\"SERVER_TASK\"), os.Getenv(\"SERVER_FAMILY\"), d.p2demand, d.p2requested)\n\tif err != nil {\n\t\tlog.Printf(\"Failed to start Priority2 tasks. %v\", err)\n\t}\n\n\treturn err\n}\n\n\/\/ update checks for changes in demand, returning true if demand changed\n\/\/ Note that this function makes no judgement on whether a demand change is\n\/\/ significant. handle() will determine that.\nfunc (d *Demand) update() bool {\n\t\/\/log.Println(\"demand update check.\")\n\tvar demandchange bool = false\n\n\tcontainer_count, err := d.sched.GetContainerCount(\"priority1-demand\")\n\tif err != nil {\n\t\tlog.Printf(\"Failed to get container count. %v\", err)\n\t\treturn false\n\t}\n\t\/\/log.Printf(\"container count %v\\n\", container_count)\n\n\t\/\/Update our saved p1 demand\n\toldP1, _ := d.set(container_count, const_maxcontainers-container_count)\n\n\t\/\/Has the demand changed?\n\tdemandchange = (container_count != oldP1)\n\n\tif demandchange {\n\t\tlog.Println(\"demandchange from, to \", oldP1, container_count)\n\t}\n\n\treturn demandchange\n}\n\n\/\/ sendStateToAPI checks the current state of cluster (or single node) and sends that\n\/\/ state to the f12 API\nfunc sendStateToAPI(currentdemand *Demand) error {\n\tcount1, count2, err := currentdemand.sched.CountAllTasks()\n\tif err != nil {\n\t\treturn fmt.Errorf(\"Failed to get state err %v\", err)\n\t}\n\n\t\/\/ Submit a PUT request to the API\n\t\/\/ Note the magic hardcoded string is the user ID, we need to pass this in in some way.

Each Apply function takes an \"apply\nconfiguration\" type as an argument, which is a structured representation of an Apply request. For\nexample:\n\n import (\n ...\n v1ac \"k8s.io\/client-go\/applyconfigurations\/autoscaling\/v1\"\n )\n hpaApplyConfig := v1ac.HorizontalPodAutoscaler(autoscalerName, ns).\n WithSpec(v1ac.HorizontalPodAutoscalerSpec().\n WithMinReplicas(0)\n )\n return hpav1client.Apply(ctx, hpaApplyConfig, metav1.ApplyOptions{FieldManager: \"mycontroller\", Force: true})\n\nNote in this example that HorizontalPodAutoscaler is imported from an \"applyconfigurations\"\npackage. Each \"apply configuration\" type represents the same Kubernetes object kind as the\ncorresponding go struct, but where all fields are pointers to make them optional, allowing apply\nrequests to be accurately represented. For example, this when the apply configuration in the above\nexample is marshalled to YAML, it produces:\n\n apiVersion: autoscaling\/v1\n kind: HorizontalPodAutoscaler\n metadata:\n name: myHPA\n namespace: myNamespace\n spec:\n minReplicas: 0\n\nTo understand why this is needed, the above YAML cannot be produced by the\nv1.HorizontalPodAutoscaler go struct. Take for example:\n\n hpa := v1.HorizontalPodAutoscaler{\n TypeMeta: metav1.TypeMeta{\n APIVersion: \"autoscaling\/v1\",\n Kind: \"HorizontalPodAutoscaler\",\n },\n ObjectMeta: ObjectMeta{\n Namespace: ns,\n Name: autoscalerName,\n },\n Spec: v1.HorizontalPodAutoscalerSpec{\n MinReplicas: pointer.Int32Ptr(0),\n },\n }\n\nThe above code attempts to declare the same apply configuration as shown in the previous examples,\nbut when marshalled to YAML, produces:\n\n kind: HorizontalPodAutoscaler\n apiVersion: autoscaling\/v1\n metadata:\n name: myHPA\n namespace: myNamespace\n creationTimestamp: null\n spec:\n scaleTargetRef:\n kind: \"\"\n name: \"\"\n minReplicas: 0\n maxReplicas: 0\n\nWhich, among other things, contains spec.maxReplicas set to 0. This is almost certainly not what\nthe caller intended (the intended apply configuration says nothing about the maxReplicas field),\nand could have serious consequences on a production system: it directs the autoscaler to downscale\nto zero pods. The problem here originates from the fact that the go structs contain required fields\nthat are zero valued if not set explicitly. The go structs work as intended for create and update\noperations, but are fundamentally incompatible with apply, which is why we have introduced the\ngenerated \"apply configuration\" types.\n\nThe \"apply configurations\" also have convenience With<FieldName> functions that make it easier to\nbuild apply requests. This allows developers to set fields without having to deal with the fact that\nall the fields in the \"apply configuration\" types are pointers, and are inconvenient to set using\ngo. For example \"MinReplicas: &0\" is not legal go code, so without the With functions, developers\nwould work around this problem by using a library, .e.g. \"MinReplicas: pointer.Int32Ptr(0)\", but\nstring enumerations like corev1.Protocol are still a problem since they cannot be supported by a\ngeneral purpose library. In addition to the convenience, the With functions also isolate\ndevelopers from the underlying representation, which makes it safer for the underlying\nrepresentation to be changed to support additional features in the future.\n\nController Support\n\nThe new client-go support makes it much easier to use Server-side Apply in controllers, by either of two mechanisms.\n\nWhen authoring new controllers to use Server-side Apply, a good approach is to have the controller\nrecreate the apply configuration for an object each time it reconciles that object. This ensures\nthat the controller fully reconciles all the fields that it is responsible for. Controllers\ntypically should unconditionally set all the fields they own by setting \"Force: true\" in the\nApplyOptions. Controllers must also provide a FieldManager name that is unique to the\nreconciliation loop that apply is called from.\n\nWhen upgrading existing controllers to use Server-side Apply the same approach often works\nwell--migrate the controllers to recreate the apply configuration each time it reconciles any\nobject. Unfortunately, the controller might have multiple code paths that update different parts of\nan object depending on various conditions. Migrating a controller like this to Server-side Apply can\nbe risky because if the controller forgets to include any fields in an apply configuration that is\nincluded in a previous apply request, a field can be accidentlly deleted. To ease this type of\nmigration, client-go apply support provides a way to replace any controller reconciliation code that\nperforms a \"read\/modify-in-place\/update\" (or patch) workflow with a \"extract\/modify-in-place\/apply\"\nworkflow. Here's an example of the new workflow:\n\n fieldMgr := \"my-field-manager\"\n deploymentClient := clientset.AppsV1().Deployments(\"default\")\n \/\/ read, could also be read from a shared informer\n deployment, err := deploymentClient.Get(ctx, \"example-deployment\", metav1.GetOptions{})\n if err != nil {\n \/\/ handle error\n }\n \/\/ extract\n deploymentApplyConfig, err := appsv1ac.ExtractDeployment(deployment, fieldMgr)\n if err != nil {\n \/\/ handle error\n }\n \/\/ modify-in-place\n deploymentApplyConfig.Spec.Template.Spec.WithContainers(corev1ac.Container().\n\tWithName(\"modify-slice\").\n\tWithImage(\"nginx:1.14.2\"),\n )\n \/\/ apply\n applied, err := deploymentClient.Apply(ctx, extractedDeployment, metav1.ApplyOptions{FieldManager: fieldMgr})\n*\/\npackage applyconfigurations\n<commit_msg>Split documentation according to both mechanisms available for migration<commit_after>\/*\nCopyright The Kubernetes Authors.\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n http:\/\/www.apache.org\/licenses\/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n*\/\n\n\/\/ Code generated by applyconfiguration-gen.

flood network. The flood\n\/\/ network is used to propagate blocks and transactions. The gateway is the\n\/\/ primary avenue that a node uses to hear about transactions and blocks, and\n\/\/ is the primary avenue used to tell the network about blocks that you have\n\/\/ mined or about transactions that you have created.\npackage gateway\n\nimport (\n\t\"time\"\n)\n\n\/\/ For the user to be securely connected to the network, the user must be\n\/\/ connected to at least one node which will send them all of the blocks. An\n\/\/ attacker can trick the user into thinking that a different blockchain is the\n\/\/ full blockchain if the user is not connected to any nodes who are seeing +\n\/\/ broadcasting the real chain (and instead is connected only to attacker nodes\n\/\/ or to nodes that are not broadcasting). This situation is called an eclipse\n\/\/ attack.\n\/\/\n\/\/ Connecting to a large number of nodes increases the resiliancy of the\n\/\/ network, but also puts a networking burden on the nodes and can slow down\n\/\/ block propagation or increase orphan rates. The gateway's job is to keep the\n\/\/ network efficient while also protecting the user against attacks.\n\/\/\n\/\/ The gateway keeps a list of nodes that it knows about. It uses this list to\n\/\/ form connections with other nodes, and then uses those connections to\n\/\/ participate in the flood network. The primary vector for an attacker to\n\/\/ achieve an eclipse attack is node list domination. If a gateway's nodelist\n\/\/ is heavily dominated by attacking nodes, then when the gateway chooses to\n\/\/ make random connections the gateway is at risk of selecting only attacker\n\/\/ nodes.\n\/\/\n\/\/ The gateway defends itself from these attacks by minimizing the amount of\n\/\/ control that an attacker has over the node list and peer list. The first\n\/\/ major defense is that the gateway maintains 8 'outbound' relationships,\n\/\/ which means that the gateway created those relationships instead of an\n\/\/ attacker. If a node forms a connection to you, that node is called\n\/\/ 'inbound', and because it may be an attacker node, it is not trusted.\n\/\/ Outbound nodes can also be attacker nodes, but they are less likely to be\n\/\/ attacker nodes because you chose them, instead of them choosing you.\n\/\/\n\/\/ If the gateway forms too many connections, the gateway will allow incoming\n\/\/ connections by kicking an existing peer. But, to limit the amount of control\n\/\/ that an attacker may have, only inbound peers are selected to be kicked.\n\/\/ Furthermore, to increase the difficulty of attack, if a new inbound\n\/\/ connection shares the same IP address as an existing connection, the shared\n\/\/ connection is the connection that gets dropped (unless that connection is a\n\/\/ local or outbound connection).\n\/\/\n\/\/ Nodes are added to a peerlist in two methods. The first method is that a\n\/\/ gateway will ask its outbound peers for a list of nodes. If the node list is\n\/\/ below a certain size (see consts.go), the gateway will repeatedly ask\n\/\/ outbound peers to expand the list. Nodes are also added to the nodelist\n\/\/ after they successfully form a connection with the gateway. To limit the\n\/\/ attacker's ability to add nodes to the nodelist, connections are\n\/\/ ratelimited. An attacker with lots of IP addresses still has the ability to\n\/\/ fill up the nodelist, however getting 90% dominance of the nodelist requires\n\/\/ forming thousands of connections, which will take hours or days. By that\n\/\/ time, the attacked node should already have its set of outbound peers,\n\/\/ limiting the amount of damage that the attacker can do.\n\/\/\n\/\/ To limit DNS-based tomfoolry, nodes are only added to the nodelist if their\n\/\/ connection information takes the form of an IP address.\n\/\/\n\/\/ Some research has been done on Bitcoin's flood networks. The more relevant\n\/\/ research has been listed below. The papers listed first are more relevant.\n\/\/ Eclipse Attacks on Bitcoin's Peer-to-Peer Network (Heilman, Kendler, Zohar, Goldberg)\n\/\/ Stubborn Mining: Generalizing Selfish Mining and Combining with an Eclipse Attack (Nayak, Kumar, Miller, Shi)\n\/\/ An Overview of BGP Hijacking (https:\/\/www.bishopfox.com\/blog\/2015\/08\/an-overview-of-bgp-hijacking\/)\n\n\/\/ TODO: Currently the gateway does not do much in terms of bucketing. The\n\/\/ gateway should make sure that it has outbound peers from a wide range of IP\n\/\/ addresses, and when kicking inbound peers it shouldn't just favor kicking\n\/\/ peers of the same IP address, it should favor kicking peers of the same ip\n\/\/ address range.\n\/\/\n\/\/ TODO: Currently the gateway does not save a list of its outbound\n\/\/ connections. When it restarts, it will have a full nodelist (which may be\n\/\/ primarily attacker nodes) and it will be connecting primarily to nodes in\n\/\/ the nodelist. Instead, it should start by trying to connect to peers that\n\/\/ have previously been outbound peers, as it is less likely that those have\n\/\/ been manipulated.\n\/\/\n\/\/ TODO: When peers connect to eachother, and when they add nodes to the node\n\/\/ list, there is no verification that the peers are running on the same Sia\n\/\/ network, something that will be problematic if we set up a large testnet.\n\/\/ It's already problematic, and currently only solved by using a different set\n\/\/ of bootstrap nodes. If there is any cross-polination (which an attacker\n\/\/ could do pretty easily), the gateways will not clean up over time, which\n\/\/ will degrade the quality of the flood network as the two networks will\n\/\/ continuously flood eachother with irrelevant information. Additionally, there\n\/\/ is no public key exhcange, so communications cannot be effectively encrypted\n\/\/ or authenticated. The nodes must have some way to share keys.\n\/\/\n\/\/ TODO: Gateway hostname discovery currently has significant centralization,\n\/\/ namely the fallback is a single third-party website that can easily form any\n\/\/ response it wants. Instead, multiple TLS-protected third party websites\n\/\/ should be used, and the plurality answer should be accepted as the true\n\/\/ hostname.\n\/\/\n\/\/ TODO: The gateway currently does hostname discovery in a non-blocking way,\n\/\/ which means that the first few peers that it connects to may not get the\n\/\/ correct hostname. This means that you may give the remote peer the wrong\n\/\/ hostname, which means they will not be able to dial you back, which means\n\/\/ they will not add you to their node list.\n\/\/\n\/\/ TODO: The gateway should encrypt and authenticate all communications. Though\n\/\/ the gateway participates in a flood network, practical attacks have been\n\/\/ demonstrated which have been able to confuse nodes by manipulating messages\n\/\/ from their peers. Encryption + authentication would have made the attack\n\/\/ more difficult.\n\/\/\n\/\/ TODO: The gateway does an unofficial ping in two places within nodes.go.\n\/\/ These unofficial pings can be found by searching for the string \"0.0.0\". To\n\/\/ perform the unofficial ping, the gateway connects to a peer and writes its\n\/\/ version as 0.0.0. When the connection completes and the handshake passes,\n\/\/ the gateway writes its version as '0.0.0', causing the other node to reject\n\/\/ the connection and disconnect. The gateway then can tell that the node on\n\/\/ the other end of the line is a Sia gateway, without having to add that node\n\/\/ as a peer. A better solution to this hack is to just add an RPC for the ping\n\/\/ function. Rollout will of course have to be gradual, as new nodes and old\n\/\/ nodes need to be able to successfully ping eachother until a sufficient\n\/\/ portion of the network has upgraded to the new code.\n\/\/\n\/\/ TODO: The gateway, when connecting to a peer, currently has no way of\n\/\/ recognizing whether that peer is itself or not. Because of this, the gateway\n\/\/ does occasionally try to connect to itself, especially if it has a really\n\/\/ small node list. This can cause problems, especially during testing, if the\n\/\/ gateway is intentionally limiting the number of local outbount peers that it\n\/\/ has. For that reason, the 'permanentPeerManager' will allow the gateway to\n\/\/ add local peers as outbound peers all the way up to 3 total connections. The\n\/\/ gateway needs a proper way to recognize if it is trying to connect itself\n\/\/ (sending a nonce when performing the version handshake, for example). Once\n\/\/ that has been implemented, maxLocalOutobundPeers can be reduced to 2 or 1\n\/\/ (probably 2).\n\nimport (\n\t\"errors\"\n\t\"fmt\"\n\t\"net\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"sync\"\n\n\t\"github.com\/NebulousLabs\/Sia\/modules\"\n\t\"github.com\/NebulousLabs\/Sia\/persist\"\n\tsiasync \"github.com\/NebulousLabs\/Sia\/sync\"\n)\n\nvar (\n\terrNoPeers = errors.New(\"no peers\")\n\terrUnreachable = errors.New(\"peer did not respond to ping\")\n)\n\n\/\/ Gateway implements the modules.Gateway interface.\ntype Gateway struct {\n\tlistener net.Listener\n\tmyAddr modules.NetAddress\n\tport string\n\n\t\/\/ handlers are the RPCs that the Gateway can handle.\n\t\/\/\n\t\/\/ initRPCs are the RPCs that the Gateway calls upon connecting to a peer.\n\thandlers map[rpcID]modules.RPCFunc\n\tinitRPCs map[string]modules.RPCFunc\n\n\t\/\/ nodes is the set of all known nodes (i.e. potential peers).\n\t\/\/\n\t\/\/ peers are the nodes that the gateway is currently connected to.\n\t\/\/\n\t\/\/ peerTG is a special thread group for tracking peer connections, and will\n\t\/\/ block shutdown until all peer connections have been closed out.

If a gateway's nodelist\n\/\/ is heavily dominated by attacking nodes, then when the gateway chooses to\n\/\/ make random connections the gateway is at risk of selecting only attacker\n\/\/ nodes.\n\/\/\n\/\/ The gateway defends itself from these attacks by minimizing the amount of\n\/\/ control that an attacker has over the node list and peer list. The first\n\/\/ major defense is that the gateway maintains 8 'outbound' relationships,\n\/\/ which means that the gateway created those relationships instead of an\n\/\/ attacker. If a node forms a connection to you, that node is called\n\/\/ 'inbound', and because it may be an attacker node, it is not trusted.\n\/\/ Outbound nodes can also be attacker nodes, but they are less likely to be\n\/\/ attacker nodes because you chose them, instead of them choosing you.\n\/\/\n\/\/ If the gateway forms too many connections, the gateway will allow incoming\n\/\/ connections by kicking an existing peer. But, to limit the amount of control\n\/\/ that an attacker may have, only inbound peers are selected to be kicked.\n\/\/ Furthermore, to increase the difficulty of attack, if a new inbound\n\/\/ connection shares the same IP address as an existing connection, the shared\n\/\/ connection is the connection that gets dropped (unless that connection is a\n\/\/ local or outbound connection).\n\/\/\n\/\/ Nodes are added to a peerlist in two methods. The first method is that a\n\/\/ gateway will ask its outbound peers for a list of nodes. If the node list is\n\/\/ below a certain size (see consts.go), the gateway will repeatedly ask\n\/\/ outbound peers to expand the list. Nodes are also added to the nodelist\n\/\/ after they successfully form a connection with the gateway. To limit the\n\/\/ attacker's ability to add nodes to the nodelist, connections are\n\/\/ ratelimited. An attacker with lots of IP addresses still has the ability to\n\/\/ fill up the nodelist, however getting 90% dominance of the nodelist requires\n\/\/ forming thousands of connections, which will take hours or days. By that\n\/\/ time, the attacked node should already have its set of outbound peers,\n\/\/ limiting the amount of damage that the attacker can do.\n\/\/\n\/\/ To limit DNS-based tomfoolry, nodes are only added to the nodelist if their\n\/\/ connection information takes the form of an IP address.\n\/\/\n\/\/ Some research has been done on Bitcoin's flood networks. The more relevant\n\/\/ research has been listed below. The papers listed first are more relevant.\n\/\/ Eclipse Attacks on Bitcoin's Peer-to-Peer Network (Heilman, Kendler, Zohar, Goldberg)\n\/\/ Stubborn Mining: Generalizing Selfish Mining and Combining with an Eclipse Attack (Nayak, Kumar, Miller, Shi)\n\/\/ An Overview of BGP Hijacking (https:\/\/www.bishopfox.com\/blog\/2015\/08\/an-overview-of-bgp-hijacking\/)\n\n\/\/ TODO: Currently the gateway does not do much in terms of bucketing. The\n\/\/ gateway should make sure that it has outbound peers from a wide range of IP\n\/\/ addresses, and when kicking inbound peers it shouldn't just favor kicking\n\/\/ peers of the same IP address, it should favor kicking peers of the same ip\n\/\/ address range.\n\/\/\n\/\/ TODO: Currently the gateway does not save a list of its outbound\n\/\/ connections. When it restarts, it will have a full nodelist (which may be\n\/\/ primarily attacker nodes) and it will be connecting primarily to nodes in\n\/\/ the nodelist. Instead, it should start by trying to connect to peers that\n\/\/ have previously been outbound peers, as it is less likely that those have\n\/\/ been manipulated.\n\/\/\n\/\/ TODO: When peers connect to eachother, and when they add nodes to the node\n\/\/ list, there is no verification that the peers are running on the same Sia\n\/\/ network, something that will be problematic if we set up a large testnet.\n\/\/ It's already problematic, and currently only solved by using a different set\n\/\/ of bootstrap nodes. If there is any cross-polination (which an attacker\n\/\/ could do pretty easily), the gateways will not clean up over time, which\n\/\/ will degrade the quality of the flood network as the two networks will\n\/\/ continuously flood eachother with irrelevant information. Additionally, there\n\/\/ is no public key exhcange, so communications cannot be effectively encrypted\n\/\/ or authenticated. The nodes must have some way to share keys.\n\/\/\n\/\/ TODO: Gateway hostname discovery currently has significant centralization,\n\/\/ namely the fallback is a single third-party website that can easily form any\n\/\/ response it wants. Instead, multiple TLS-protected third party websites\n\/\/ should be used, and the plurality answer should be accepted as the true\n\/\/ hostname.\n\/\/\n\/\/ TODO: The gateway currently does hostname discovery in a non-blocking way,\n\/\/ which means that the first few peers that it connects to may not get the\n\/\/ correct hostname. This means that you may give the remote peer the wrong\n\/\/ hostname, which means they will not be able to dial you back, which means\n\/\/ they will not add you to their node list.\n\/\/\n\/\/ TODO: The gateway should encrypt and authenticate all communications. Though\n\/\/ the gateway participates in a flood network, practical attacks have been\n\/\/ demonstrated which have been able to confuse nodes by manipulating messages\n\/\/ from their peers. Encryption + authentication would have made the attack\n\/\/ more difficult.\n\/\/\n\/\/ TODO: The gateway does an unofficial ping in two places within nodes.go.\n\/\/ These unofficial pings can be found by searching for the string \"0.0.0\". To\n\/\/ perform the unofficial ping, the gateway connects to a peer and writes its\n\/\/ version as 0.0.0. When the connection completes and the handshake passes,\n\/\/ the gateway writes its version as '0.0.0', causing the other node to reject\n\/\/ the connection and disconnect. The gateway then can tell that the node on\n\/\/ the other end of the line is a Sia gateway, without having to add that node\n\/\/ as a peer. A better solution to this hack is to just add an RPC for the ping\n\/\/ function. Rollout will of course have to be gradual, as new nodes and old\n\/\/ nodes need to be able to successfully ping eachother until a sufficient\n\/\/ portion of the network has upgraded to the new code.\n\/\/\n\/\/ TODO: The gateway, when connecting to a peer, currently has no way of\n\/\/ recognizing whether that peer is itself or not. Because of this, the gateway\n\/\/ does occasionally try to connect to itself, especially if it has a really\n\/\/ small node list. This can cause problems, especially during testing, if the\n\/\/ gateway is intentionally limiting the number of local outbount peers that it\n\/\/ has. For that reason, the 'permanentPeerManager' will allow the gateway to\n\/\/ add local peers as outbound peers all the way up to 3 total connections. The\n\/\/ gateway needs a proper way to recognize if it is trying to connect itself\n\/\/ (sending a nonce when performing the version handshake, for example). Once\n\/\/ that has been implemented, maxLocalOutobundPeers can be reduced to 2 or 1\n\/\/ (probably 2).\n\nimport (\n\t\"errors\"\n\t\"fmt\"\n\t\"net\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"sync\"\n\n\t\"github.com\/NebulousLabs\/Sia\/modules\"\n\t\"github.com\/NebulousLabs\/Sia\/persist\"\n\tsiasync \"github.com\/NebulousLabs\/Sia\/sync\"\n)\n\nvar (\n\terrNoPeers = errors.New(\"no peers\")\n\terrUnreachable = errors.New(\"peer did not respond to ping\")\n)\n\n\/\/ Gateway implements the modules.Gateway interface.\ntype Gateway struct {\n\tlistener net.Listener\n\tmyAddr modules.NetAddress\n\tport string\n\n\t\/\/ handlers are the RPCs that the Gateway can handle.\n\t\/\/\n\t\/\/ initRPCs are the RPCs that the Gateway calls upon connecting to a peer.\n\thandlers map[rpcID]modules.RPCFunc\n\tinitRPCs map[string]modules.RPCFunc\n\n\t\/\/ nodes is the set of all known nodes (i.e. potential peers).\n\t\/\/\n\t\/\/ peers are the nodes that the gateway is currently connected to.\n\t\/\/\n\t\/\/ peerTG is a special thread group for tracking peer connections, and will\n\t\/\/ block shutdown until all peer connections have been closed out.

For example, on Unix systems, the crash raises\nSIGABRT to trigger a core dump.\nFor historical reasons, the GOTRACEBACK settings 0, 1, and 2 are synonyms for\nnone, all, and system, respectively.\nThe runtime\/debug package's SetTraceback function allows increasing the\namount of output at run time, but it cannot reduce the amount below that\nspecified by the environment variable.\nSee https:\/\/golang.org\/pkg\/runtime\/debug\/#SetTraceback.\n\nThe GOARCH, GOOS, GOPATH, and GOROOT environment variables complete\nthe set of Go environment variables. They influence the building of Go programs\n(see https:\/\/golang.org\/cmd\/go and https:\/\/golang.org\/pkg\/go\/build).\nGOARCH, GOOS, and GOROOT are recorded at compile time and made available by\nconstants or functions in this package, but they do not influence the execution\nof the run-time system.\n*\/\npackage runtime\n\nimport (\n\t\"internal\/goarch\"\n\t\"internal\/goos\"\n)\n\n\/\/ Caller reports file and line number information about function invocations on\n\/\/ the calling goroutine's stack. The argument skip is the number of stack frames\n\/\/ to ascend, with 0 identifying the caller of Caller. (For historical reasons the\n\/\/ meaning of skip differs between Caller and Callers.) The return values report the\n\/\/ program counter, file name, and line number within the file of the corresponding\n\/\/ call.

CallersFrames accounts\n\/\/ for inlined functions and adjusts the return program counters into\n\/\/ call program counters. Iterating over the returned slice of PCs\n\/\/ directly is discouraged, as is using FuncForPC on any of the\n\/\/ returned PCs, since these cannot account for inlining or return\n\/\/ program counter adjustment.\nfunc Callers(skip int, pc []uintptr) int {\n\t\/\/ runtime.callers uses pc.array==nil as a signal\n\t\/\/ to print a stack trace.
