Value type variables point directly to their value contained in memory.\n\t\/\/ All types explored in previous sections except \"pointer\", \"slice\", \"map\",\n\t\/\/ and \"channel\" are value types.\n\n\t\/\/ 2. Reference types variable \"pointer, slice, map, and channel\", contains the\n\t\/\/ address of the memory location where the value is stored.\n\n\t\/\/ Merory allocation in Go\n\t\/\/------------------------\n\t\/\/ Go has two allocation primitives, the built-in functions new and make. \n\t\/\/ They do different things and apply to different types, which can be \n\t\/\/ confusing, but the rules are simple.\n\n\t\/\/ allocation with new\n\t\/\/------------------------\n\t\/\/ Let's talk about new first.

A server registers an object, making it visible\n\tas a service with the name of the type of the object.  After registration, public\n\tmethods of the object will be accessible remotely.  A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn.  More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection.  The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection).  The resulting\n\tClient object has two methods, Call and Go, that specify the service and method to\n\tcall, a structure containing the arguments, and a structure to receive the result\n\tparameters.\n\n\tCall waits for the remote call to complete; Go launches the call asynchronously\n\tand returns a channel that will signal completion.\n\n\tPackage \"gob\" is used to transport the data.\n\n\tHere is a simple example.  A server wishes to export an object of type Arith:\n\n\t\tpackage server\n\n\t\ttype Args struct {\n\t\t\tA, B int\n\t\t}\n\n\t\ttype Reply struct {\n\t\t\tC int\n\t\t}\n\n\t\ttype Arith int\n\n\t\tfunc (t *Arith) Multiply(args *Args, reply *Reply) os.Error {\n\t\t\treply.C = args.A * args.B;\n\t\t\treturn nil\n\t\t}\n\n\t\tfunc (t *Arith) Divide(args *Args, reply *Reply) os.Error {\n\t\t\tif args.B == 0 {\n\t\t\t\treturn os.ErrorString(\"divide by zero\");\n\t\t\t}\n\t\t\treply.C = args.A \/ args.B;\n\t\t\treturn nil\n\t\t}\n\n\tThe server calls (for HTTP service):\n\n\t\tarith := new(Arith);\n\t\trpc.Register(arith);\n\t\trrpc.HandleHTTP();\n\t\tl, e := net.Listen(\"tcp\", \":1234\");\n\t\tif e != nil {\n\t\t\tlog.Exit(\"listen error:\", e);\n\t\t}\n\t\tgo http.Serve(l, nil);\n\n\tAt this point, clients can see a service \"Arith\" with methods \"Arith.Multiply\" and\n\t\"Arith.Divide\".  To invoke one, a client first dials the server:\n\n\t\tclient, err := rpc.DialHTTP(\"tcp\", serverAddress + \":1234\");\n\t\tif err != nil {\n\t\t\tlog.Exit(\"dialing:\", err);\n\t\t}\n\n\tThen it can make a remote call:\n\n\t\t\/\/ Synchronous call\n\t\targs := &server.Args{7,8};\n\t\treply := new(server.Reply);\n\t\terr = client.Call(\"Arith.Multiply\", args, reply);\n\t\tif err != nil {\n\t\t\tlog.Exit(\"arith error:\", err);\n\t\t}\n\t\tfmt.Printf(\"Arith: %d*%d=%d\", args.A, args.B, reply.C);\n\n\tor\n\n\t\t\/\/ Asynchronous call\n\t\tdivCall := client.Go(\"Arith.Divide\", args, reply, nil);\n\t\treplyCall := <-divCall.Done;\t\/\/ will be equal to divCall\n\t\t\/\/ check errors, print, etc.\n\n\tA server implementation will often provide a simple, type-safe wrapper for the\n\tclient.\n*\/\npackage rpc\n\nimport (\n\t\"gob\";\n\t\"http\";\n\t\"log\";\n\t\"io\";\n\t\"net\";\n\t\"os\";\n\t\"reflect\";\n\t\"strings\";\n\t\"sync\";\n\t\"unicode\";\n\t\"utf8\";\n)\n\n\/\/ Precompute the reflect type for os.Error.

A server registers an object, making it visible\n\tas a service with the name of the type of the object.  After registration, public\n\tmethods of the object will be accessible remotely.  A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn.  More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection.  The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection).  The resulting\n\tClient object has two methods, Call and Go, that specify the service and method to\n\tcall, a structure containing the arguments, and a structure to receive the result\n\tparameters.\n\n\tCall waits for the remote call to complete; Go launches the call asynchronously\n\tand returns a channel that will signal completion.\n\n\tPackage \"gob\" is used to transport the data.\n\n\tHere is a simple example.  A server wishes to export an object of type Arith:\n\n\t\tpackage server\n\n\t\ttype Args struct {\n\t\t\tA, B int\n\t\t}\n\n\t\ttype Reply struct {\n\t\t\tC int\n\t\t}\n\n\t\ttype Arith int\n\n\t\tfunc (t *Arith) Multiply(args *Args, reply *Reply) os.Error {\n\t\t\treply.C = args.A * args.B;\n\t\t\treturn nil\n\t\t}\n\n\t\tfunc (t *Arith) Divide(args *Args, reply *Reply) os.Error {\n\t\t\tif args.B == 0 {\n\t\t\t\treturn os.ErrorString(\"divide by zero\");\n\t\t\t}\n\t\t\treply.C = args.A \/ args.B;\n\t\t\treturn nil\n\t\t}\n\n\tThe server calls (for HTTP service):\n\n\t\tarith := new(Arith);\n\t\trpc.Register(arith);\n\t\trpc.HandleHTTP();\n\t\tl, e := net.Listen(\"tcp\", \":1234\");\n\t\tif e != nil {\n\t\t\tlog.Exit(\"listen error:\", e);\n\t\t}\n\t\tgo http.Serve(l, nil);\n\n\tAt this point, clients can see a service \"Arith\" with methods \"Arith.Multiply\" and\n\t\"Arith.Divide\".  To invoke one, a client first dials the server:\n\n\t\tclient, err := rpc.DialHTTP(\"tcp\", serverAddress + \":1234\");\n\t\tif err != nil {\n\t\t\tlog.Exit(\"dialing:\", err);\n\t\t}\n\n\tThen it can make a remote call:\n\n\t\t\/\/ Synchronous call\n\t\targs := &server.Args{7,8};\n\t\treply := new(server.Reply);\n\t\terr = client.Call(\"Arith.Multiply\", args, reply);\n\t\tif err != nil {\n\t\t\tlog.Exit(\"arith error:\", err);\n\t\t}\n\t\tfmt.Printf(\"Arith: %d*%d=%d\", args.A, args.B, reply.C);\n\n\tor\n\n\t\t\/\/ Asynchronous call\n\t\tdivCall := client.Go(\"Arith.Divide\", args, reply, nil);\n\t\treplyCall := <-divCall.Done;\t\/\/ will be equal to divCall\n\t\t\/\/ check errors, print, etc.\n\n\tA server implementation will often provide a simple, type-safe wrapper for the\n\tclient.\n*\/\npackage rpc\n\nimport (\n\t\"gob\";\n\t\"http\";\n\t\"log\";\n\t\"io\";\n\t\"net\";\n\t\"os\";\n\t\"reflect\";\n\t\"strings\";\n\t\"sync\";\n\t\"unicode\";\n\t\"utf8\";\n)\n\n\/\/ Precompute the reflect type for os.Error.

applied in the right order. We define a special pattern type that always\n\/\/ matches so long as it's greater than or equal to the global test index. By\n\/\/ incrementing this index, we can invalidate all routes up to some point, and\n\/\/ therefore test the routing guarantee that Goji provides: for any path P, if\n\/\/ both A and B match P, and if A was inserted before B, then Goji will route to\n\/\/ A before it routes to B.\nvar rsRoutes =

See https:\/\/godoc.org\/cloud.google.com\/go for a full list\nof sub-packages.\n\n\nAuthentication and Authorization\n\nAll the clients in sub-packages support authentication via Google Application Default\nCredentials (see https:\/\/cloud.google.com\/docs\/authentication\/production), or\nby providing a JSON key file for a Service Account. See the authentication examples\nin this package for details.\n\n\nTimeouts and Cancellation\n\nBy default, all requests in sub-packages will run indefinitely, retrying on transient\nerrors when correctness allows. To set timeouts or arrange for cancellation, use\ncontexts. See the examples for details.\n\nDo not attempt to control the initial connection (dialing) of a service by setting a\ntimeout on the context passed to NewClient. Dialing is non-blocking, so timeouts\nwould be ineffective and would only interfere with credential refreshing, which uses\nthe same context.\n\n\nConnection Pooling\n\nConnection pooling differs in clients based on their transport. Cloud\nclients either rely on HTTP or gRPC transports to communicate\nwith Google Cloud.\n\nCloud clients that use HTTP (bigquery, compute, storage, and translate) rely on the\nunderlying HTTP transport to cache connections for later re-use. These are cached to\nthe default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in\nhttp.DefaultTransport.\n\nFor gPRC clients (all others in this repo), connection pooling is configurable.

See https:\/\/godoc.org\/cloud.google.com\/go for a full list\nof sub-packages.\n\n\nAuthentication and Authorization\n\nAll the clients in sub-packages support authentication via Google Application Default\nCredentials (see https:\/\/cloud.google.com\/docs\/authentication\/production), or\nby providing a JSON key file for a Service Account. See the authentication examples\nin this package for details.\n\n\nTimeouts and Cancellation\n\nBy default, all requests in sub-packages will run indefinitely, retrying on transient\nerrors when correctness allows. To set timeouts or arrange for cancellation, use\ncontexts. See the examples for details.\n\nDo not attempt to control the initial connection (dialing) of a service by setting a\ntimeout on the context passed to NewClient. Dialing is non-blocking, so timeouts\nwould be ineffective and would only interfere with credential refreshing, which uses\nthe same context.\n\n\nConnection Pooling\n\nConnection pooling differs in clients based on their transport. Cloud\nclients either rely on HTTP or gRPC transports to communicate\nwith Google Cloud.\n\nCloud clients that use HTTP (bigquery, compute, storage, and translate) rely on the\nunderlying HTTP transport to cache connections for later re-use. These are cached to\nthe default http.MaxIdleConns and http.MaxIdleConnsPerHost settings in\nhttp.DefaultTransport.\n\nFor gPRC clients (all others in this repo), connection pooling is configurable. Users\nof cloud client libraries may specify option.WithGRPCConnectionPool(n) as a client\noption to NewClient calls. This configures the underlying gRPC connections to be\npooled and addressed in a round robin fashion.\n\n\nUsing the Libraries with Docker\n\nMinimal docker images like Alpine lack CA certificates. This causes RPCs to appear to\nhang, because gRPC retries indefinitely. See https:\/\/github.com\/GoogleCloudPlatform\/google-cloud-go\/issues\/928\nfor more information.\n\nDebugging\n\nTo see gRPC logs, set the environment variable GRPC_GO_LOG_SEVERITY_LEVEL. See\nhttps:\/\/godoc.org\/google.golang.org\/grpc\/grpclog for more information.\n\nFor HTTP logging, set the GODEBUG environment variable to \"http2debug=1\" or \"http2debug=2\".\n*\/\npackage cloud \/\/ import \"cloud.google.com\/go\"\n<|endoftext|>"}

{"text":"<commit_before>\/\/ Package goa standardizes on structured error responses: a request that fails because of\n\/\/ invalid input or unexpected condition produces a response that contains one or more structured\n\/\/ error(s). Each error object has three keys: a id (number), a title and a message. The title\n\/\/ for a given id is always the same, the intent is to provide a human friendly categorization.\n\/\/ The message is specific to the error occurrence and provides additional details that often\n\/\/ include contextual information (name of parameters etc.).\n\/\/\n\/\/ The basic data structure backing errors is TypedError which simply contains the id and message.\n\/\/ Multiple errors (not just TypedError instances) can be encapsulated in a MultiError. Both\n\/\/ TypedError and MultiError implement the error interface, the Error methods return valid JSON\n\/\/ that can be written directly to a response body.\n\/\/\n\/\/ The code generated by goagen calls the helper functions exposed in this file when it encounters\n\/\/ invalid data (wrong type, validation errors etc.) such as InvalidParamTypeError,\n\/\/ InvalidAttributeTypeError etc. These methods take and return an error which is a MultiError that\n\/\/ gets built over time. The final MultiError object then gets serialized into the response and sent\n\/\/ back to the client. The response status code is inferred from the type wrapping the error object:\n\/\/ a BadRequestError produces a 400 status code while any other error produce a 500.

because of\n\/\/ invalid input or unexpected condition produces a response that contains one or more structured\n\/\/ error(s). Each error object has three keys: a id (number), a title and a message. The title\n\/\/ for a given id is always the same, the intent is to provide a human friendly categorization.\n\/\/ The message is specific to the error occurrence and provides additional details that often\n\/\/ include contextual information (name of parameters etc.).\n\/\/\n\/\/ The basic data structure backing errors is TypedError which simply contains the id and message.\n\/\/ Multiple errors (not just TypedError instances) can be encapsulated in a MultiError. Both\n\/\/ TypedError and MultiError implement the error interface, the Error methods return valid JSON\n\/\/ that can be written directly to a response body.\n\/\/\n\/\/ The code generated by goagen calls the helper functions exposed in this file when it encounters\n\/\/ invalid data (wrong type, validation errors etc.) such as InvalidParamTypeError,\n\/\/ InvalidAttributeTypeError etc. These methods take and return an error which is a MultiError that\n\/\/ gets built over time. The final MultiError object then gets serialized into the response and sent\n\/\/ back to the client. The response status code is inferred from the type wrapping the error object:\n\/\/ a BadRequestError produces a 400 status code while any other error produce a 500. This behavior\n\/\/ can be overridden by setting a custom ErrorHandler in the application.\npackage goa\n\nimport (\n\t\"fmt\"\n\t\"strings\"\n)\n\nvar (\n\t\/\/ ErrInvalidParamType is the class of

{"text":"<commit_before>\/\/ The `fwd` package provides a buffered reader\n\/\/ and writer. Each has methods that help improve\n\/\/ the encoding\/decoding performance of some binary\n\/\/ protocols.\n\/\/\n\/\/ The `fwd.Writer` and `fwd.Reader` type provide similar\n\/\/ functionality to their counterparts in `bufio`, plus\n\/\/ a few extra utility methods that simplify read-ahead\n\/\/ and write-ahead. I wrote this package to improve serialization\n\/\/ performance for http:\/\/github.com\/tinylib\/msgp,\n\/\/ where it provided about a 2x speedup over `bufio` for certain\n\/\/ workloads. However, care must be taken to understand the semantics of the\n\/\/ extra methods provided by this package, as they allow\n\/\/ the user to access and manipulate the buffer memory\n\/\/ directly.\n\/\/\n\/\/ The extra methods for `fwd.Reader` are `Peek`, `Skip`\n\/\/ and `Next`. `(*fwd.Reader).Peek`, unlike `(*bufio.Reader).Peek`,\n\/\/ will re-allocate the read buffer in order to accommodate arbitrarily\n\/\/ large read-ahead. `(*fwd.Reader).Skip` skips the next `n` bytes\n\/\/ in the stream, and uses the `io.Seeker` interface if the underlying\n\/\/ stream implements it. `(*fwd.Reader).Next` returns a slice pointing\n\/\/ to the next `n` bytes in the read buffer (like `Peek`), but also\n\/\/ increments the read position. This allows users to process streams\n\/\/ in arbitrary block sizes without having to manage appropriately-sized\n\/\/ slices. Additionally, obviating the need to copy the data from the\n\/\/ buffer to another location in memory can improve performance dramatically\n\/\/ in CPU-bound applications.\n\/\/\n\/\/ `fwd.Writer` only has one extra method, which is `(*fwd.Writer).Next`, which\n\/\/ returns a slice pointing to the next `n` bytes of the writer, and increments\n\/\/ the write position by the length of the returned slice.

Each has methods that help improve\n\/\/ the encoding\/decoding performance of some binary\n\/\/ protocols.\n\/\/\n\/\/ The `fwd.Writer` and `fwd.Reader` type provide similar\n\/\/ functionality to their counterparts in `bufio`, plus\n\/\/ a few extra utility methods that simplify read-ahead\n\/\/ and write-ahead. I wrote this package to improve serialization\n\/\/ performance for http:\/\/github.com\/tinylib\/msgp,\n\/\/ where it provided about a 2x speedup over `bufio` for certain\n\/\/ workloads. However, care must be taken to understand the semantics of the\n\/\/ extra methods provided by this package, as they allow\n\/\/ the user to access and manipulate the buffer memory\n\/\/ directly.\n\/\/\n\/\/ The extra methods for `fwd.Reader` are `Peek`, `Skip`\n\/\/ and `Next`. `(*fwd.Reader).Peek`, unlike `(*bufio.Reader).Peek`,\n\/\/ will re-allocate the read buffer in order to accommodate arbitrarily\n\/\/ large read-ahead. `(*fwd.Reader).Skip` skips the next `n` bytes\n\/\/ in the stream, and uses the `io.Seeker` interface if the underlying\n\/\/ stream implements it. `(*fwd.Reader).Next` returns a slice pointing\n\/\/ to the next `n` bytes in the read buffer (like `Peek`), but also\n\/\/ increments the read position. This allows users to process streams\n\/\/ in arbitrary block sizes without having to manage appropriately-sized\n\/\/ slices. Additionally, obviating the need to copy the data from the\n\/\/ buffer to another location in memory can improve performance dramatically\n\/\/ in CPU-bound applications.\n\/\/\n\/\/ `fwd.Writer` only has one extra method, which is `(*fwd.Writer).Next`, which\n\/\/ returns a slice pointing to the next `n` bytes of the writer, and increments\n\/\/ the write position by the length of the returned slice. This allows users\n\/\/ to write directly to the end of the buffer.\n\/\/\npackage fwd\n\nimport \"io\"\n\nconst (\n\t\/\/ DefaultReaderSize is the default size of the read buffer\n\tDefaultReaderSize = 2048\n\n\t\/\/ minimum read buffer; straight from bufio\n\tminReaderSize = 16\n)\n\n\/\/ NewReader returns a new *Reader that reads from 'r'\nfunc NewReader(r io.Reader) *Reader {\n\treturn NewReaderSize(r, DefaultReaderSize)\n}\n\n\/\/ NewReaderSize returns a new *Reader that\n\/\/ reads from 'r' and has a buffer size 'n'\nfunc NewReaderSize(r io.Reader, n int) *Reader {\n\trd := &Reader{\n\t\tr:    r,\n\t\tdata: make([]byte, 0, max(minReaderSize, n)),\n\t}\n\tif s, ok := r.(io.Seeker); ok {\n\t\trd.rs = s\n\t}\n\treturn rd\n}\n\n\/\/ Reader is a buffered look-ahead reader\ntype Reader struct {\n\tr io.Reader \/\/ underlying reader\n\n\t\/\/ data[n:len(data)] is buffered data; data[len(data):cap(data)] is free buffer space\n\tdata  []byte \/\/ data\n\tn     int    \/\/ read offset\n\tstate error  \/\/ last read error\n\n\t\/\/ if the reader past to NewReader was\n\t\/\/ also an io.Seeker, this is non-nil\n\trs io.Seeker\n}\n\n\/\/ Reset resets the underlying reader\n\/\/ and the read buffer.\nfunc (r *Reader) Reset(rd io.Reader) {\n\tr.r = rd\n\tr.data = r.data[0:0]\n\tr.n = 0\n\tr.state = nil\n\tif s, ok := rd.(io.Seeker); ok {\n\t\tr.rs = s\n\t} else {\n\t\tr.rs = nil\n\t}\n}\n\n\/\/ more() does one read on the underlying reader\nfunc (r *Reader) more() {\n\t\/\/ move data backwards so that\n\t\/\/ the read offset is 0; this way\n\t\/\/ we can supply the maximum number of\n\t\/\/ bytes to the reader\n\tif r.n != 0 {\n\t\tif r.n < len(r.data) {\n\t\t\tr.data = r.data[:copy(r.data[0:], r.data[r.n:])]\n\t\t} else {\n\t\t\tr.data = r.data[:0]\n\t\t}\n\t\tr.n = 0\n\t}\n\tvar a int\n\ta, r.state = r.r.Read(r.data[len(r.data):cap(r.data)])\n\tif a == 0 && r.state == nil {\n\t\tr.state = io.ErrNoProgress\n\t\treturn\n\t} else if a > 0 && r.state == io.EOF {\n\t\t\/\/ discard the io.EOF if we read more than 0 bytes.\n\t\t\/\/ the next call to Read should return io.EOF again.\n\t\tr.state = nil\n\t}\n\tr.data = r.data[:len(r.data)+a]\n}\n\n\/\/ pop error\nfunc (r *Reader) err() (e error) {\n\te, r.state = r.state, nil\n\treturn\n}\n\n\/\/ pop error; EOF -> io.ErrUnexpectedEOF\nfunc (r *Reader) noEOF() (e error) {\n\te, r.state = r.state, nil\n\tif e == io.EOF {\n\t\te = io.ErrUnexpectedEOF\n\t}\n\treturn\n}\n\n\/\/ buffered bytes\nfunc (r *Reader) buffered() int { return len(r.data) - r.n }\n\n\/\/ Buffered returns the number of bytes currently in the buffer\nfunc (r *Reader) Buffered() int { return len(r.data) - r.n }\n\n\/\/ BufferSize returns the total size of the buffer\nfunc (r *Reader) BufferSize() int { return cap(r.data) }\n\n\/\/ Peek returns the next 'n' buffered bytes,\n\/\/ reading from the underlying reader if necessary.\n\/\/ It will only return a slice shorter than 'n' bytes\n\/\/ if it also returns an error.

While the methods\n\/\/ are called Head and Tail, they are not considered directed unless the given interface specifies\n\/\/ otherwise.\ntype Edge interface {\n\tHead() Node\n\tTail() Node\n}\n\n\/\/ A Graph implements the behavior of an undirected graph.\n\/\/\n\/\/ All methods in Graph are implicitly undirected. Graph algorithms that care about directionality\n\/\/ will intelligently choose the DirectedGraph behavior if that interface is also implemented,\n\/\/ even if the function itself only takes in a Graph (or a super-interface of graph).\ntype Graph interface {\n\t\/\/ NodeExists returns true when node is currently in the graph.\n\tNodeExists(Node) bool\n\n\t\/\/ NodeList returns a list of all nodes in no particular order, useful for\n\t\/\/ determining things like if a graph is fully connected. The caller is\n\t\/\/ free to modify this list. Implementations should construct a new list\n\t\/\/ and not return internal representation.\n\tNodeList() []Node\n\n\t\/\/ Neighbors returns all nodes connected by any edge to this node.\n\tNeighbors(Node) []Node\n\n\t\/\/ EdgeBetween returns an edge between node and neighbor such that\n\t\/\/ Head is one argument and Tail is the other. If no\n\t\/\/ such edge exists, this function returns nil.\n\tEdgeBetween(node, neighbor Node) Edge\n}\n\n\/\/ Directed graphs are characterized by having seperable Heads and Tails in their edges.\n\/\/ That is, if node1 goes to node2, that does not necessarily imply that node2 goes to node1.\n\/\/\n\/\/ While it's possible for a directed graph to have fully reciprocal edges (i.e. the graph is\n\/\/ symmetric) -- it is not required to be. The graph is also required to implement Graph\n\/\/ because in many cases it can be useful to know all neighbors regardless of direction.\ntype DirectedGraph interface {\n\tGraph\n\t\/\/ Successors gives the nodes connected by OUTBOUND edges.\n\t\/\/ If the graph is an undirected graph, this set is equal to Predecessors.\n\tSuccessors(Node) []Node\n\n\t\/\/ EdgeTo returns an edge between node and successor such that\n\t\/\/ Head returns node and Tail returns successor, if no\n\t\/\/ such edge exists, this function returns nil.\n\tEdgeTo(node, successor Node) Edge\n\n\t\/\/ Predecessors gives the nodes connected by INBOUND edges.\n\t\/\/ If the graph is an undirected graph, this set is equal to Successors.\n\tPredecessors(Node) []Node\n}\n\n\/\/ Returns all undirected edges in the graph\ntype EdgeLister interface {\n\tEdgeList() []Edge\n}\n\ntype EdgeListGraph interface {\n\tGraph\n\tEdgeLister\n}\n\n\/\/ Returns all directed edges in the graph.\ntype DirectedEdgeLister interface {\n\tDirectedEdgeList() []Edge\n}\n\ntype DirectedEdgeListGraph interface {\n\tGraph\n\tDirectedEdgeLister\n}\n\n\/\/ A crunch graph forces a sparse graph to become a dense graph. That is, if the node IDs are\n\/\/ [1,4,9,7] it would \"crunch\" the ids into the contiguous block [0,1,2,3]. Order is not\n\/\/ required to be preserved between the non-cruched and crunched instances (that means in\n\/\/ the example above 0 may correspond to 4 or 7 or 9, not necessarily 1).\n\/\/\n\/\/ All dense graphs must have the first ID as 0.\ntype CrunchGraph interface {\n\tGraph\n\tCrunch()\n}\n\n\/\/ A Graph that implements Coster has an actual cost between adjacent nodes, also known as a\n\/\/ weighted graph. If a graph implements coster and a function needs to read cost (e.g. A*),\n\/\/ this function will take precedence over the Uniform Cost function (all weights are 1) if \"nil\"\n\/\/ is passed in for the function argument.\n\/\/\n\/\/ If the argument is nil, or the edge is invalid for some reason, this should return math.Inf(1)\ntype Coster interface {\n\tCost(edge Edge) float64\n}\n\ntype CostGraph interface {\n\tCoster\n\tGraph\n}\n\ntype CostDirectedGraph interface {\n\tCoster\n\tDirectedGraph\n}\n\n\/\/ A graph that implements HeuristicCoster implements a heuristic between any two given nodes.\n\/\/ Like Coster, if a graph implements this and a function needs a heuristic cost (e.g. A*), this\n\/\/ function will take precedence over the Null Heuristic (always returns 0) if \"nil\" is passed in\n\/\/ for the function argument. If HeuristicCost is not intended to be used, it can be implemented as\n\/\/ the null heuristic (always returns 0.)\ntype HeuristicCoster interface {\n\t\/\/ HeuristicCost returns a heuristic cost between any two nodes.\n\tHeuristicCost(n1, n2 Node) float64\n}\n\n\/\/ A Mutable is a graph that can have arbitrary nodes and edges added or removed.\n\/\/\n\/\/ Anything implementing Mutable is required to store the actual argument. So if AddNode(myNode) is\n\/\/ called and later a user calls on the graph graph.NodeList(), the node added by AddNode must be\n\/\/ an the exact node, not a new node with the same ID.\n\/\/\n\/\/ In any case where conflict is possible (e.g. adding two nodes with the same ID), the later\n\/\/ call always supercedes the earlier one.\n\/\/\n\/\/ Functions will generally expect one of MutableGraph or MutableDirectedGraph and not Mutable\n\/\/ itself. That said, any function that takes Mutable[x], the destination mutable should\n\/\/ always be a different graph than the source.\ntype Mutable interface {\n\t\/\/ NewNode adds a node with an arbitrary ID and returns the new, unique ID\n\t\/\/ used.\n\tNewNode() Node\n\n\t\/\/ Adds a node to the graph. If this is called multiple times for the same ID, the newer node\n\t\/\/ overwrites the old one.\n\tAddNode(Node)\n\n\t\/\/ RemoveNode removes a node from the graph, as well as any edges\n\t\/\/ attached to it. If no such node exists, this is a no-op, not an error.\n\tRemoveNode(Node)\n}\n\n\/\/ MutableGraph is an interface ensuring the implementation of the ability to construct\n\/\/ an arbitrary undirected graph. It is very important to note that any implementation\n\/\/ of MutableGraph absolutely cannot safely implement the DirectedGraph interface.\n\/\/\n\/\/ A MutableGraph is required to store any Edge argument in the same way Mutable must\n\/\/ store a Node argument -- any retrieval call is required to return the exact supplied edge.\n\/\/ This is what makes it incompatible with DirectedGraph.\n\/\/\n\/\/ The reasoning is this: if you call AddUndirectedEdge(Edge{head,tail}); you are required\n\/\/ to return the exact edge passed in when a retrieval method (EdgeTo\/EdgeBetween) is called.\n\/\/ If I call EdgeTo(tail,head), this means that since the edge exists, and was added as\n\/\/ Edge{head,tail} this function MUST return Edge{head,tail}. However, EdgeTo requires this\n\/\/ be returned as Edge{tail,head}. Thus there's a conflict that cannot be resolved between the\n\/\/ two interface requirements.\ntype MutableGraph interface {\n\tCostGraph\n\tMutable\n\n\t\/\/ Like EdgeBetween in Graph, AddUndirectedEdge adds an edge between two nodes.\n\t\/\/ If one or both nodes do not exist, the graph is expected to add them. However,\n\t\/\/ if the nodes already exist it should NOT replace existing nodes with e.Head() or\n\t\/\/ e.Tail(). Overwriting nodes should explicitly be done with another call to AddNode()\n\tAddUndirectedEdge(e Edge, cost float64)\n\n\t\/\/ RemoveEdge clears the stored edge between two nodes. Calling this will never\n\t\/\/ remove a node. If the edge does not exist this is a no-op, not an error.\n\tRemoveUndirectedEdge(Edge)\n}\n\n\/\/ MutableDirectedGraph is an interface that ensures one can construct an arbitrary directed\n\/\/ graph. Naturally, a MutableDirectedGraph works for both undirected and directed cases,\n\/\/ but simply using a MutableGraph may be cleaner. As the documentation for MutableGraph\n\/\/ notes, however, a graph cannot safely implement MutableGraph and MutableDirectedGraph\n\/\/ at the same time, because of the functionality of a EdgeTo in DirectedGraph.\ntype MutableDirectedGraph interface {\n\tCostDirectedGraph\n\tMutable\n\n\t\/\/ Like EdgeTo in DirectedGraph, AddDirectedEdge adds an edge FROM head TO tail.\n\t\/\/ If one or both nodes do not exist, the graph is expected to add them.

Aliasing is useful when supporting\n\/\/ forks without needing to rewrite the imports in a codebase.\n\/\/\n\/\/ A glide.yaml file looks like:\n\/\/\n\/\/ \t\tpackage: github.com\/Masterminds\/glide\n\/\/ \t\timports:\n\/\/\t\t\t- package: github.com\/Masterminds\/cookoo\n\/\/\t\t\t  vcs: git\n\/\/\t\t\t  ref: 1.1.0\n\/\/\t\t\t  subpackages: **\n\/\/\t\t\t- package: github.com\/kylelemons\/go-gypsy\n\/\/\t\t\t  subpackages: yaml\n\/\/\n\/\/ Glide puts dependencies in a _vendor directory. Go utilities require this to\n\/\/ be in your GOPATH. Glide makes this easy. Use the `glide in` command to enter\n\/\/ a shell (your default) with the GOPATH set to the projects _vendor directory.\n\/\/ To leave this shell simply exit it.\n\/\/\n\/\/ If your .bashrc, .zshrc, or other startup shell sets your GOPATH you many need\n\/\/ to optionally set it using something like:\n\/\/\n\/\/\t\tif [ \"\" = \"${GOPATH}\" ]; then\n\/\/\t\t  export GOPATH=\"\/some\/dir\"\n\/\/\t\tfi\n\/\/\n\/\/ For more information use the `glide help` command or see https:\/\/github.com\/Masterminds\/glide\npackage main\n\nimport (\n\t\"github.com\/Masterminds\/glide\/cmd\"\n\n\t\"github.com\/Masterminds\/cookoo\"\n\t\/\/\"github.com\/Masterminds\/cookoo\/cli\"\n\n\t\"github.com\/codegangsta\/cli\"\n\n\t\"flag\"\n\t\"os\"\n)\n\nvar version string = \"0.2.0-dev\"\n\nconst Summary = \"Manage Go projects with ease.\"\nconst Usage = `Manage dependencies, naming, and GOPATH for your Go projects.\n\nExamples:\n\t$ glide create\n\t$ glide in\n\t$ glide install\n\t$ glide update\n\t$ glide rebuild\n\nCOMMANDS\n========\n\nDependency management:\n\n- create: Initialize a new project, creating a template glide.yaml.\n- install: Install all packages in the glide.yaml.\n- update: Update existing packages (alias: 'up').\n- rebuild: Rebuild ('go build') the dependencies.\n\nFILES\n=====\n\nEach project should have a 'glide.yaml' file in the project directory.

Things like ruby, perl, gcc,\n      python, php, go, node are preinstalled on your VM. You can start\n      writing code right away without the need for new installs!\n\n      Here are a few additional commonly asked questions. For more, head\n      over to Koding University at http:\/\/learn.koding.com\n\n      Some things to note:\n      - The default web server root is linked to \/home\/{{ .Username }}\/Web\n        so any file placed inside that directory will automatically\n        be visible from this URL:\n        http:\/\/{{.UserDomain}}\n\n      - You can access this VM using any sub-domains that you may have\n        set up. To learn more about sub-domains and how to set them up,\n        please read this article on Koding University:\n        http:\/\/learn.koding.com\/domains\n\n      - To run a command as the ` + \"`\" + `root` + \"`\" + ` user, prefix any command with\n        ` + \"`\" + `sudo <command>` + \"`\" + `. Remember, with great power, comes great\n        responsibility! :)\n\n      Common questions:\n      ================\n      # How can I find out which packages are installed on my VM?\n\n      Run the command: ` + \"`\" + `dpkg --get-selections | grep -v deinstall` + \"`\" + ` to get\n      a list of all installed packages. If a particular package is not\n      installed, go ahead and install it using ` + \"`\" + `sudo apt-get install\n      <package name>` + \"`\" + `. Using this command you can install databases like\n      postgres, MySQL, Mongo, etc.\n\n      # What is my sudo password?\n\n      By default, you sudo password is blank. Most people like it that\n      way but if you prefer, you can use the ` + \"`\" + `sudo passwd` + \"`\" + ` command and\n      change the default (blank) password to something more secure.\n\n      # How do I poweroff my VM?\n      For our free acccounts, the VMs will power off automatically after\n      60 minutes of inactivity. However, if you wish to poweroff your\n      VM manually, please use the VM settings panel to achieve that.\n\n\n      For more questions and FAQ, head over to http:\/\/learn.koding.com\n      or send us an email at support@koding.com\n    path: \/home\/{{.Username}}\/README.md\n\n\n{{if .ShouldMigrate }}\n  # User migration script (~\/migrate.sh)\n  - content: |\n      #!\/bin\/bash\n      username={{.Username}}\n      credentials=({{.Passwords}})\n      vm_names=({{.VmNames}})\n      vm_ids=({{.VmIds}})\n      count=$((${#credentials[@]} - 1))\n      counter=0\n      clear\n      if [ -f \/etc\/koding\/.kodingart.txt ]; then\n        cat \/etc\/koding\/.kodingart.txt\n      fi\n      echo\n      echo 'This migration assistant will help you move your VMs from the old Koding'\n      echo 'environment to the new one.

Things like ruby, perl, gcc,\n      python, php, go, node are preinstalled on your VM. You can start\n      writing code right away without the need for new installs!\n\n      Here are a few additional commonly asked questions. For more, head\n      over to Koding University at http:\/\/learn.koding.com\n\n      Some things to note:\n      - The default web server root is linked to \/home\/{{ .Username }}\/Web\n        so any file placed inside that directory will automatically\n        be visible from this URL:\n        http:\/\/{{.UserDomain}}\n\n      - You can access this VM using any sub-domains that you may have\n        set up. To learn more about sub-domains and how to set them up,\n        please read this article on Koding University:\n        http:\/\/learn.koding.com\/domains\n\n      - To run a command as the ` + \"`\" + `root` + \"`\" + ` user, prefix any command with\n        ` + \"`\" + `sudo <command>` + \"`\" + `. Remember, with great power, comes great\n        responsibility! :)\n\n      Common questions:\n      ================\n      # How can I find out which packages are installed on my VM?\n\n      Run the command: ` + \"`\" + `dpkg --get-selections | grep -v deinstall` + \"`\" + ` to get\n      a list of all installed packages. If a particular package is not\n      installed, go ahead and install it using ` + \"`\" + `sudo apt-get install\n      <package name>` + \"`\" + `. Using this command you can install databases like\n      postgres, MySQL, Mongo, etc.\n\n      # What is my sudo password?\n\n      By default, you sudo password is blank. Most people like it that\n      way but if you prefer, you can use the ` + \"`\" + `sudo passwd` + \"`\" + ` command and\n      change the default (blank) password to something more secure.\n\n      # How do I poweroff my VM?\n      For our free acccounts, the VMs will power off automatically after\n      60 minutes of inactivity. However, if you wish to poweroff your\n      VM manually, please use the VM settings panel to achieve that.\n\n\n      For more questions and FAQ, head over to http:\/\/learn.koding.com\n      or send us an email at support@koding.com\n    path: \/home\/{{.Username}}\/README.md\n\n\n{{if .ShouldMigrate }}\n  # User migration script (~\/migrate.sh)\n  - content: |\n      #!\/bin\/bash\n      username={{.Username}}\n      credentials=({{.Passwords}})\n      vm_names=({{.VmNames}})\n      vm_ids=({{.VmIds}})\n      count=$((${#credentials[@]} - 1))\n      counter=0\n      clear\n      if [ -f \/etc\/koding\/.kodingart.txt ]; then\n        cat \/etc\/koding\/.kodingart.txt\n      fi\n      echo\n      echo 'This migration assistant will help you move your VMs from the old Koding'\n      echo 'environment to the new one.

With this format, Serf will only send events\n    of that type to that script.\n\n  - The value can be in the format of \"user:EVENT=SCRIPT\", such as\n    \"user:deploy=deploy.sh\". This means that Serf will only invoke this\n    script in the case of user events named \"deploy\".\n`\n\treturn strings.TrimSpace(helpText)\n}\n<commit_msg>agent: handle signals directly for configurable behavior<commit_after>package agent\n\nimport (\n\t\"flag\"\n\t\"fmt\"\n\t\"github.com\/hashicorp\/logutils\"\n\t\"github.com\/hashicorp\/memberlist\"\n\t\"github.com\/hashicorp\/serf\/serf\"\n\t\"github.com\/mitchellh\/cli\"\n\t\"io\"\n\t\"log\"\n\t\"net\"\n\t\"os\"\n\t\"os\/signal\"\n\t\"strings\"\n\t\"syscall\"\n\t\"time\"\n)\n\n\/\/ gracefulTimeout controls how long we wait before forcefully terminating\nvar gracefulTimeout = 3 * time.Second\n\n\/\/ Command is a Command implementation that runs a Serf agent.\n\/\/ The command will not end unless a shutdown message is sent on the\n\/\/ ShutdownCh.

With this format, Serf will only send events\n    of that type to that script.\n\n  - The value can be in the format of \"user:EVENT=SCRIPT\", such as\n    \"user:deploy=deploy.sh\". This means that Serf will only invoke this\n    script in the case of user events named \"deploy\".\n`\n\treturn strings.TrimSpace(helpText)\n}\n<|endoftext|>"}

It acts similar to json's\n\/\/ Unmarshal when used on a struct, but works with any codec\n\/\/ registered with AddCodec().\n\/\/\n\/\/ Field tags are used as follows:\n\/\/\n\/\/ * All field tags are considered to be of the format\n\/\/ name,option1,option2,...\n\/\/\n\/\/ * Options will *only* be parsed from the \"request\" tag.\n\/\/\n\/\/ * By default, name will only be checked in the \"request\" tag, but\n\/\/ you can add fallback tag names using AddFallbackTag.\n\/\/\n\/\/ * If no non-empty name is found using field tags, the lowercase\n\/\/ field name will be used instead.\n\/\/\n\/\/ * Once a name is found, if the name is \"-\", then the field will be\n\/\/ treated as if it does not exist.\n\/\/\n\/\/ For an explanation on how options work, see the documentation for\n\/\/ RegisterOption.  For a list of tag options built in to this\n\/\/ library, see the options package in this package.\n\/\/\n\/\/ Fields which have no data in the request will be left as their\n\/\/ current value.  They will still be passed through the option parser\n\/\/ for the purposes of options like \"required\".\n\/\/\n\/\/ Fields which implement Receiver will have their Receive method\n\/\/ called using the value from the request after calling all\n\/\/ OptionFuncs matching the field's tag options.\n\/\/\n\/\/ An error will be returned if the target type is not a pointer to a\n\/\/ struct, or if the target implements PreUnmarshaller, Unmarshaller,\n\/\/ or PostUnmarshaller and the corresponding methods fail.

For a list of tag options built in to this\n\/\/ library, see the options package in this package.\n\/\/\n\/\/ Fields which have no data in the request will be left as their\n\/\/ current value.  They will still be passed through the option parser\n\/\/ for the purposes of options like \"required\".\n\/\/\n\/\/ Fields which implement Receiver will have their Receive method\n\/\/ called using the value from the request after calling all\n\/\/ OptionFuncs matching the field's tag options.\n\/\/\n\/\/ An error will be returned if the target type is not a pointer to a\n\/\/ struct, or if the target implements PreUnmarshaller, Unmarshaller,\n\/\/ or PostUnmarshaller and the corresponding methods fail.  An\n\/\/ UnusedFields error will be returned if fields in the request had no\n\/\/ corresponding fields on the target struct.\n\/\/\n\/\/ Any errors encountered while attempting to apply input values to\n\/\/ the target's fields will be stored in an error of type InputErrors.\n\/\/ At the end of the Unmarshal process, the InputErrors error will be\n\/\/ returned if any errors were encountered.\n\/\/\n\/\/ A simple example:\n\/\/\n\/\/     type Example struct {\n\/\/         Foo string `request:\",required\"`\n\/\/         Bar string `response:\"baz\"`\n\/\/         Baz string `response:\"-\"`\n\/\/         Bacon string `response:\"-\" request:\"bacon,required\"`\n\/\/     }\n\/\/\n\/\/     func CreateExample(request *http.Request) (*Example, error) {\n\/\/         target := new(Example)\n\/\/         if err := requests.New(request).Unmarshal(target); err != nil {\n\/\/             if inputErrs, ok := err.(InputErrors); ok {\n\/\/                 \/\/ inputErrs is a map of input names to error\n\/\/                 \/\/ messages, so send them to a function to turn\n\/\/                 \/\/ them into a proper user-friendly error message.\n\/\/                 return nil, userErrors(inputErrs)\n\/\/             }\n\/\/             return nil, err\n\/\/         }\n\/\/         return target, nil\n\/\/     }\n\/\/\nfunc (request *Request) Unmarshal(target interface{}) error {\n\treturn request.unmarshal(target, false)\n}\n\n\/\/ unmarshal performes all of the logic for Unmarshal and\n\/\/ UnmarshalReplace.\nfunc (request *Request) unmarshal(target interface{}, replace bool) (unmarshalErr error) {\n\ttargetValue := reflect.ValueOf(target)\n\tif targetValue.Kind() != reflect.Ptr || targetValue.Elem().Kind() != reflect.Struct {\n\t\treturn errors.New(\"The value passed to Unmarshal must be a pointer to a struct\")\n\t}\n\ttargetValue = targetValue.Elem()\n\tparams, err := request.Params()\n\tif err != nil {\n\t\treturn err\n\t}\n\n\tif preUnmarshaller, ok := target.(PreUnmarshaller); ok {\n\t\tif unmarshalErr = preUnmarshaller.PreUnmarshal(); unmarshalErr != nil {\n\t\t\treturn\n\t\t}\n\t}\n\tif postUnmarshaller, ok := target.(PostUnmarshaller); ok {\n\t\tdefer func() {\n\t\t\tif unmarshalErr == nil {\n\t\t\t\tunmarshalErr = postUnmarshaller.PostUnmarshal()\n\t\t\t}\n\t\t}()\n\t}\n\tif unmarshaller, ok := target.(Unmarshaller); ok {\n\t\treturn unmarshaller.Unmarshal(params)\n\t}\n\n\tmatchedFields, inputErrs := unmarshalToValue(params, targetValue, replace)\n\tif len(inputErrs) > 0 {\n\t\treturn inputErrs\n\t}\n\n\tunused := &UnusedFields{\n\t\tparams:  params,\n\t\tmatched: matchedFields,\n\t}\n\tif unused.HasMissing() {\n\t\treturn unused\n\t}\n\treturn nil\n}\n\n\/\/ unmarshalToValue is a helper for UnmarshalParams, which keeps track\n\/\/ of the total number of fields matched in a request and which fields\n\/\/ were missing from a request.\nfunc unmarshalToValue(params map[string]interface{}, targetValue reflect.Value, replace bool) (matchedFields set, parseErrs InputErrors) {\n\tmatchedFields = make(set, 0, len(params))\n\tparseErrs = make(InputErrors)\n\tdefer func() {\n\t\t\/\/ Clean up any nil errors from the error map.\n\t\tparseErrs = parseErrs.Errors()\n\t}()\n\n\ttargetType := targetValue.Type()\n\tfor i := 0; i < targetValue.NumField(); i++ {\n\t\tfieldValue := targetValue.Field(i)\n\t\tfield := targetType.Field(i)\n\t\tif field.Anonymous {\n\t\t\t\/\/ Ignore non-struct anonymous fields, but treat fields in\n\t\t\t\/\/ struct or struct pointer anonymous fields as if they\n\t\t\t\/\/ were fields on the child struct.\n\t\t\tif fieldValue.Kind() == reflect.Ptr {\n\t\t\t\tfieldValue = fieldValue.Elem()\n\t\t\t}\n\t\t\tif fieldValue.Kind() == reflect.Struct {\n\t\t\t\tembeddedFields, newErrs := unmarshalToValue(params, fieldValue, replace)\n\t\t\t\tif newErrs != nil {\n\t\t\t\t\t\/\/ Override input errors in the anonymous field\n\t\t\t\t\t\/\/ with input errors in the child.

For our purposes we will consider MDP-optimizing safe.\n\/\/ [3] Requests in the same PNGroup will need to be normalized together anyway.\n\/\/     Because the consolidation function for normalization is always set taking into account the rollups that we have (see executePlan()) we can better read from a coarser archive.\n\/\/     Any request in a PNGroup has already been vetted to be worthy of pre-normalization, thus there is absolutely no loss of information.\n\/\/\n\/\/ planRequests follows these steps:\n\/\/ 1) Initial parameters.\n\/\/    select the highest resolution possible within TTL for all requests. there's 4 cases:\n\/\/    * requests in the same PNGroup,    and MDP-optimizable: reduce aggressively: to longest common interval such that points >=MDP\/2\n\/\/    * requests in the same PNGroup but not MDP-optimizable: reduce conservatively: to shortest common interval that still meets TTL\n\/\/    * MDP optimizable singles     : longest interval such that points >= MDP\/2\n\/\/    * non-MDP-optimizable singles : shortest interval that still meets TTL\n\/\/\n\/\/ 2) apply max-points-per-req-soft (meaning: pick coarser data as needed)\n\/\/    The optimizations in the previous step should increase the odds of meeting this limit.\n\/\/    If we still breach this limit, we could\n\/\/    a) reduce the already MDP-optimized ones further but that would definitely result in loss of accuracy\n\/\/    b) reduce non-MDP-optimizable series.\n\/\/    For \"fairness\" across series, and because we used to simply reduce any series without regard for how it would be used, we pick the latter. better would be both\n\/\/ 3) subject to max-points-per-req-hard: reject the query if it can't be met\n\/\/\n\/\/ note: it is assumed that all requests have the same from & to.\n\/\/ also takes a \"now\" value which we compare the TTL against\nfunc planRequests(now, from, to uint32, reqs *ReqMap, planMDP uint32, mpprSoft, mpprHard int) (*ReqsPlan, error) {\n\n\tok, rp := false, NewReqsPlan(*reqs)\n\n\tfor group, split := range rp.pngroups {\n\t\tif len(split.mdpno) > 0 {\n\t\t\tsplit.mdpno, ok = planHighestResMulti(now, from, to, split.mdpno)\n\t\t\tif !ok {\n\t\t\t\treturn nil, errUnSatisfiable\n\t\t\t}\n\t\t}\n\t\tif len(split.mdpyes) > 0 {\n\t\t\tsplit.mdpyes, ok = planLowestResForMDPMulti(now, from, to, split.mdpyes)\n\t\t\tif !ok {\n\t\t\t\treturn nil, errUnSatisfiable\n\t\t\t}\n\t\t\trp.pngroups[group] = split\n\t\t}\n\t}\n\tfor i, req := range rp.single.mdpno {\n\t\trp.single.mdpno[i], ok = planHighestResSingle(now, from, to, req)\n\t\tif !ok {\n\t\t\treturn nil, errUnSatisfiable\n\t\t}\n\t}\n\tfor i, req := range rp.single.mdpyes {\n\t\trp.single.mdpyes[i], ok = planLowestResForMDPSingle(now, from, to, req)\n\t\tif !ok {\n\t\t\treturn nil, errUnSatisfiable\n\t\t}\n\t}\n\n\tif mpprSoft > 0 {\n\t\t\/\/ at this point, all MDP-optimizable series have already been optimized\n\t\t\/\/ we can try to reduce the resolution of non-MDP-optimizable series\n\t\t\/\/ if metrictank is already handling all, or most of your queries, then we have been able to determine\n\t\t\/\/ MDP-optimizability very well.

Each version represents a single state\n\t\/\/ of mutation for the given Json and Blob hash. The Id, allows each\n\t\/\/ version of, say, a single File or Wiki page to have the same identifier\n\t\/\/ and represent the same item.\n\t\/\/\n\t\/\/ Ids can be random or contain meaning, the usage is entirely up to the\n\t\/\/ user.\n\tId string `json:\"id,omitempty\"`\n\n\t\/\/ UploadedAt is used to track the Version over time, and sort the most recent.\n\t\/\/\n\t\/\/ This is important, as many versions of a single id have to be sorted somehow.\n\t\/\/ Sorting them by PreviousVersionCount and PreviousVersionHash is possible,\n\t\/\/ but that leads itself to conflicts which then have to be resolved, merged,\n\t\/\/ etc.\n\t\/\/\n\t\/\/ Sorting by time allows for automatic resolution of any conflict, and is\n\t\/\/ the most hands-free method of conflict resolution. Not guaranteed to be\n\t\/\/ correct, but guaranteed to be easy.\n\tUploadedAt *time.Time `json:\"uploadedAt,omitempty\"`\n\n\t\/\/ PreviousVersionHash stores the Version preceeding this Version, if any.\n\t\/\/\n\t\/\/ This not only provides a historical record of each mutation, but it can\n\t\/\/ help identify version forks. A fork in this case, is when multiple\n\t\/\/ writers write based off of the same PreviousVersionHash. Since Fixity\n\t\/\/ stores data by content address, forks and \"conflicts\" are not\n\t\/\/ problematic, but can cause confusion to the actual writer of the data.\n\tPreviousVersionHash string `json:\"previousVersion,omitempty\"`\n\n\t\/\/ ChangeLog is a simple human friendly message about this Version.\n\tChangeLog string `json:\"changeLog,omitempty\"`\n}\n\n\/\/ MultiJson is a JsonWithMetas map, keyed for unordered unmarshalling.\n\/\/\n\/\/ MultiJson differs from MultiJsonHash in that MultiJson is supplied by\n\/\/ users, and contains the JsonBytes. MultiJsonHash is stored within\n\/\/ the Fixity.Store, and does *not* contain the JsonBytes. The Bytes are\n\/\/ stored separately, as to separate the Meta from the actual Content.\n\/\/\n\/\/ MultiJson and MultiJsonHash allow a writer to store multiple json structs\n\/\/ together, within a single Commit.\n\/\/\n\/\/ A single Commit Write can support an arbitrary number of Json documents via\n\/\/ the MultiJson map. Each Json value within the JsonWithMeta is stored as\n\/\/ it's own content address.\n\/\/\n\/\/ This allows the caller to optimize how the data is stored. Ensuring that\n\/\/ frequently changing data is not stored with infrequently changing data,\n\/\/ effectively manually deduplicating the json.\n\/\/\n\/\/ This method of deduplication, vs rolling checksums as seen in Blobs,\n\/\/ is chosen because the caller of Write is able to effectively choose\n\/\/ the rolling splits by seperating Json out into separate objects.\n\/\/ Furthermore, for rolling checksums to be effective with smaller documents\n\/\/ the rolling algorithm would need to chunk at very small intervals,\n\/\/ introducing a lot of extra documents in the store with little gain.\n\/\/\n\/\/ Finally, and most importantly, storing Json as chunked bytes would cause\n\/\/ the json to effectively be encoded. No longer is the content \"just json\",\n\/\/ but rather you need to join bytes together to construct your actual data,\n\/\/ as is the case with binary blobs. Blobs don't have a choice on this, as\n\/\/ Binary isn't Json, but Json does.

Each version represents a single state\n\t\/\/ of mutation for the given Json and Blob hash. The Id, allows each\n\t\/\/ version of, say, a single File or Wiki page to have the same identifier\n\t\/\/ and represent the same item.\n\t\/\/\n\t\/\/ Ids can be random or contain meaning, the usage is entirely up to the\n\t\/\/ user.\n\tId string `json:\"id,omitempty\"`\n\n\t\/\/ UploadedAt is used to track the Version over time, and sort the most recent.\n\t\/\/\n\t\/\/ This is important, as many versions of a single id have to be sorted somehow.\n\t\/\/ Sorting them by PreviousVersionCount and PreviousVersionHash is possible,\n\t\/\/ but that leads itself to conflicts which then have to be resolved, merged,\n\t\/\/ etc.\n\t\/\/\n\t\/\/ Sorting by time allows for automatic resolution of any conflict, and is\n\t\/\/ the most hands-free method of conflict resolution. Not guaranteed to be\n\t\/\/ correct, but guaranteed to be easy.\n\tUploadedAt *time.Time `json:\"uploadedAt,omitempty\"`\n\n\t\/\/ PreviousVersionHash stores the Version preceeding this Version, if any.\n\t\/\/\n\t\/\/ This not only provides a historical record of each mutation, but it can\n\t\/\/ help identify version forks. A fork in this case, is when multiple\n\t\/\/ writers write based off of the same PreviousVersionHash. Since Fixity\n\t\/\/ stores data by content address, forks and \"conflicts\" are not\n\t\/\/ problematic, but can cause confusion to the actual writer of the data.\n\tPreviousVersionHash string `json:\"previousVersion,omitempty\"`\n\n\t\/\/ ChangeLog is a simple human friendly message about this Version.\n\tChangeLog string `json:\"changeLog,omitempty\"`\n}\n\n\/\/ MultiJson is a JsonWithMetas map, keyed for unordered unmarshalling.\n\/\/\n\/\/ MultiJson differs from MultiJsonHash in that MultiJson is supplied by\n\/\/ users, and contains the JsonBytes. MultiJsonHash is stored within\n\/\/ the Fixity.Store, and does *not* contain the JsonBytes. The Bytes are\n\/\/ stored separately, as to separate the Meta from the actual Content.\n\/\/\n\/\/ MultiJson and MultiJsonHash allow a writer to store multiple json structs\n\/\/ together, within a single Commit.\n\/\/\n\/\/ A single Commit Write can support an arbitrary number of Json documents via\n\/\/ the MultiJson map. Each Json value within the JsonWithMeta is stored as\n\/\/ it's own content address.\n\/\/\n\/\/ This allows the caller to optimize how the data is stored. Ensuring that\n\/\/ frequently changing data is not stored with infrequently changing data,\n\/\/ effectively manually deduplicating the json.\n\/\/\n\/\/ This method of deduplication, vs rolling checksums as seen in Blobs,\n\/\/ is chosen because the caller of Write is able to effectively choose\n\/\/ the rolling splits by seperating Json out into separate objects.\n\/\/ Furthermore, for rolling checksums to be effective with smaller documents\n\/\/ the rolling algorithm would need to chunk at very small intervals,\n\/\/ introducing a lot of extra documents in the store with little gain.\n\/\/\n\/\/ Finally, and most importantly, storing Json as chunked bytes would cause\n\/\/ the json to effectively be encoded. No longer is the content \"just json\",\n\/\/ but rather you need to join bytes together to construct your actual data,\n\/\/ as is the case with binary blobs. Blobs don't have a choice on this, as\n\/\/ Binary isn't Json, but Json does.

{"text":"<commit_before>\/*\n\nPackage freeze enables the \"freezing\" of data, similar to JavaScript's\nObject.freeze(). A frozen object cannot be modified; attempting to do so will\nresult in an unrecoverable panic.\n\nFreezing is useful for providing soft guarantees of immutability. That is: the\ncompiler can't prevent you from mutating an frozen object, but the runtime\ncan. One of the unfortunate aspects of Go is its limited support for\nconstants: structs, slices, and even arrays cannot be declared as consts. This\nbecomes a problem when you want to pass a slice around to many consumers\nwithout worrying about them modifying it. With freeze, you can guard against\nthese unwanted or intended behaviors.\n\nTo accomplish this, the mprotect syscall is used. Sadly, this necessitates\nallocating new memory via mmap and copying the data into it. This performance\npenalty should not be prohibitive, but it's something to be aware of.\n\nIn case it wasn't clear from the previous paragraph, this package is not\nintended to be used in production. A well-designed API is a much saner\nsolution than freezing your data structures. I would even caution against\nusing freeze in your automated testing, due to its platform-specific nature.\nfreeze is best used for \"one-off\" debugging. Something like this:\n\n1. Observe bug\n2. Suspect that shared mutable data is the culprit\n3. Call freeze.Object on the data after it is created\n4. Run program again; it crashes\n5. Inspect stack trace to identify where the data was modified\n6. Fix bug\n7. Remove call to freeze.Object\n\nAgain: do not use freeze in production. It's a cool proof-of-concept, and it\ncan be useful for debugging, but that's about it. Let me put it another way:\nfreeze imports four packages: reflect, runtime, unsafe, and syscall (actually\ngolang.org\/x\/sys\/unix). Does that sound like a package you want to depend on?\n\nOkay, back to the real documention:\n\nFunctions are provided for freezing the three \"pointer types:\" Pointer, Slice,\nand Map. Each function returns a copy of their input that is backed by\nprotected memory. In addition, Object is provided for freezing recursively.\nGiven a slice of pointers, Object will prevent modifications to both the\npointer data and the slice data, while Slice merely does the latter.\n\nTo freeze an object:\n\n\ttype foo struct {\n\t\tX int\n\t\ty bool \/\/ yes, freeze works on unexported fields!\n\t}\n\tf := &foo{3, true}\n\tf = freeze.Object(f).(*foo)\n\tprintln(f.X) \/\/ ok; prints 3\n\tf.X++        \/\/ not ok; panics\n\nNote that since foo does not contain any pointers, calling Pointer(f) would\nhave the same effect here.\n\nIt is recommended that, where convenient, you reassign the return value to its\noriginal variable, as with append. Otherwise, you will retain both the mutable\noriginal and the frozen copy.\n\nLikewise, to freeze a slice:\n\n\txs := []int{1, 2, 3}\n\txs = freeze.Slice(xs).([]int)\n\tprintln(xs[0]) \/\/ ok; prints 1\n\txs[0]++        \/\/ not ok; panics\n\nInterfaces can also be frozen, since internally they are just pointers to\nobjects. The effect of this is that the interface's pure methods can still be\ncalled, but impure methods cannot. Unfortunately the impurity of a given\nmethod is defined by the implementation, not the interface. Even a String\nmethod could conceivably modify some internal state. Furthermore, the caveat\nabout unexported struct fields (see below) applies here, so many exported\nobjects cannot be completely frozen.\n\nCaveats\n\nThis package depends heavily on the internal representations of the slice and\nmap types. These objects are not likely to change, but if they do, this\npackage will break.\n\nIn general, you can't call Object on the same object twice. This is because\nObject will attempt to rewrite the object's internal pointers -- which is a\nmemory modification. Calling Pointer or Slice twice should be fine.\n\nObject cannot descend into unexported struct fields. It can still freeze the\nfield itself, but if the field contains a pointer, the data it points to will\nnot be frozen.\n\nAppending to a frozen slice will trigger a panic iff len(slice) < cap(slice).\nThis is because appending to a full slice will allocate new memory.\n\nUnix is the only supported platform. Windows support is not planned, because\nit doesn't support a syscall analogous to mprotect.\n*\/\npackage freeze\n\nimport (\n\t\"reflect\"\n\t\"runtime\"\n\t\"unsafe\"\n\n\t\"golang.org\/x\/sys\/unix\"\n)\n\n\/\/ Pointer returns a frozen copy of v, which must be a pointer.

In addition, Object is provided for freezing recursively.\nGiven a slice of pointers, Object will prevent modifications to both the\npointer data and the slice data, while Slice merely does the latter.\n\nTo freeze an object:\n\n\ttype foo struct {\n\t\tX int\n\t\ty bool \/\/ yes, freeze works on unexported fields!\n\t}\n\tf := &foo{3, true}\n\tf = freeze.Object(f).(*foo)\n\tprintln(f.X) \/\/ ok; prints 3\n\tf.X++        \/\/ not ok; panics\n\nNote that since foo does not contain any pointers, calling Pointer(f) would\nhave the same effect here.\n\nIt is recommended that, where convenient, you reassign the return value to its\noriginal variable, as with append. Otherwise, you will retain both the mutable\noriginal and the frozen copy.\n\nLikewise, to freeze a slice:\n\n\txs := []int{1, 2, 3}\n\txs = freeze.Slice(xs).([]int)\n\tprintln(xs[0]) \/\/ ok; prints 1\n\txs[0]++        \/\/ not ok; panics\n\nInterfaces can also be frozen, since internally they are just pointers to\nobjects. The effect of this is that the interface's pure methods can still be\ncalled, but impure methods cannot. Unfortunately the impurity of a given\nmethod is defined by the implementation, not the interface. Even a String\nmethod could conceivably modify some internal state. Furthermore, the caveat\nabout unexported struct fields (see below) applies here, so many exported\nobjects cannot be completely frozen.\n\nCaveats\n\nThis package depends heavily on the internal representations of the slice and\nmap types. These objects are not likely to change, but if they do, this\npackage will break.\n\nIn general, you can't call Object on the same object twice. This is because\nObject will attempt to rewrite the object's internal pointers -- which is a\nmemory modification. Calling Pointer or Slice twice should be fine.\n\nObject cannot descend into unexported struct fields. It can still freeze the\nfield itself, but if the field contains a pointer, the data it points to will\nnot be frozen.\n\nAppending to a frozen slice will trigger a panic iff len(slice) < cap(slice).\nThis is because appending to a full slice will allocate new memory.\n\nUnix is the only supported platform. Windows support is not planned, because\nit doesn't support a syscall analogous to mprotect.\n*\/\npackage freeze\n\nimport (\n\t\"reflect\"\n\t\"runtime\"\n\t\"unsafe\"\n\n\t\"golang.org\/x\/sys\/unix\"\n)\n\n\/\/ Pointer returns a frozen copy of v, which must be a pointer.

assert\n<commit_msg>Fix tiny typo<commit_after>\/\/ Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.\n\/\/\n\/\/ Example Usage\n\/\/\n\/\/ The following is a complete example using assert in a standard test function:\n\/\/    import (\n\/\/      \"testing\"\n\/\/      \"github.com\/stretchr\/testify\/assert\"\n\/\/    )\n\/\/\n\/\/    func TestSomething(t *testing.T) {\n\/\/\n\/\/      var a string = \"Hello\"\n\/\/      var b string = \"Hello\"\n\/\/\n\/\/      assert.Equal(t, a, b, \"The two words should be the same.\")\n\/\/\n\/\/    }\n\/\/\n\/\/ if you assert many times, use the format below:\n\/\/\n\/\/    import (\n\/\/      \"testing\"\n\/\/      \"github.com\/stretchr\/testify\/assert\"\n\/\/    )\n\/\/\n\/\/    func TestSomething(t *testing.T) {\n\/\/      assert := assert.New(t)\n\/\/\n\/\/      var a string = \"Hello\"\n\/\/      var b string = \"Hello\"\n\/\/\n\/\/      assert.Equal(a, b, \"The two words should be the same.\")\n\/\/    }\n\/\/\n\/\/ Assertions\n\/\/\n\/\/ Assertions allow you to easily write test code, and are global funcs in the `assert` package.\n\/\/ All assertion functions take, as the first argument, the `*testing.T` object provided by the\n\/\/ testing framework. This allows the assertion funcs to write the failings and other details to\n\/\/ the correct place.\n\/\/\n\/\/ Every assertion function also takes an optional string message as the final argument,\n\/\/ allowing custom error messages to be appended to the message the assertion method outputs.\n\/\/\n\/\/ Here is an overview of the assert functions:\n\/\/\n\/\/    assert.Equal(t, expected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.EqualValues(t, expected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.NotEqual(t, notExpected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.True(t, actualBool [, message [, format-args]])\n\/\/\n\/\/    assert.False(t, actualBool [, message [, format-args]])\n\/\/\n\/\/    assert.Nil(t, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.NotNil(t, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Empty(t, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.NotEmpty(t, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Len(t, actualObject, expectedLength, [, message [, format-args]])\n\/\/\n\/\/    assert.Error(t, errorObject [, message [, format-args]])\n\/\/\n\/\/    assert.NoError(t, errorObject [, message [, format-args]])\n\/\/\n\/\/    assert.EqualError(t, theError, errString [, message [, format-args]])\n\/\/\n\/\/    assert.Implements(t, (*MyInterface)(nil), new(MyObject) [,message [, format-args]])\n\/\/\n\/\/    assert.IsType(t, expectedObject, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Contains(t, stringOrSlice, substringOrElement [, message [, format-args]])\n\/\/\n\/\/    assert.NotContains(t, stringOrSlice, substringOrElement [, message [, format-args]])\n\/\/\n\/\/    assert.Panics(t, func(){\n\/\/\n\/\/\t    \/\/ call code that should panic\n\/\/\n\/\/    } [, message [, format-args]])\n\/\/\n\/\/    assert.NotPanics(t, func(){\n\/\/\n\/\/\t    \/\/ call code that should not panic\n\/\/\n\/\/    } [, message [, format-args]])\n\/\/\n\/\/    assert.WithinDuration(t, timeA, timeB, deltaTime, [, message [, format-args]])\n\/\/\n\/\/    assert.InDelta(t, numA, numB, delta, [, message [, format-args]])\n\/\/\n\/\/    assert.InEpsilon(t, numA, numB, epsilon, [, message [, format-args]])\n\/\/\n\/\/ assert package contains Assertions object. it has assertion methods.\n\/\/\n\/\/ Here is an overview of the assert functions:\n\/\/    assert.Equal(expected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.EqualValues(expected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.NotEqual(notExpected, actual [, message [, format-args]])\n\/\/\n\/\/    assert.True(actualBool [, message [, format-args]])\n\/\/\n\/\/    assert.False(actualBool [, message [, format-args]])\n\/\/\n\/\/    assert.Nil(actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.NotNil(actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Empty(actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.NotEmpty(actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Len(actualObject, expectedLength, [, message [, format-args]])\n\/\/\n\/\/    assert.Error(errorObject [, message [, format-args]])\n\/\/\n\/\/    assert.NoError(errorObject [, message [, format-args]])\n\/\/\n\/\/    assert.EqualError(theError, errString [, message [, format-args]])\n\/\/\n\/\/    assert.Implements((*MyInterface)(nil), new(MyObject) [,message [, format-args]])\n\/\/\n\/\/    assert.IsType(expectedObject, actualObject [, message [, format-args]])\n\/\/\n\/\/    assert.Contains(stringOrSlice, substringOrElement [, message [, format-args]])\n\/\/\n\/\/    assert.NotContains(stringOrSlice, substringOrElement [, message [, format-args]])\n\/\/\n\/\/    assert.Panics(func(){\n\/\/\n\/\/\t    \/\/ call code that should panic\n\/\/\n\/\/    } [, message [, format-args]])\n\/\/\n\/\/    assert.NotPanics(func(){\n\/\/\n\/\/\t    \/\/ call code that should not panic\n\/\/\n\/\/    } [, message [, format-args]])\n\/\/\n\/\/    assert.WithinDuration(timeA, timeB, deltaTime, [, message [, format-args]])\n\/\/\n\/\/    assert.InDelta(numA, numB, delta, [, message [, format-args]])\n\/\/\n\/\/    assert.InEpsilon(numA, numB, epsilon, [, message [, format-args]])\npackage assert\n<|endoftext|>"}

For\n\/\/your specific game, Game and Players will actually be concrete structs to\n\/\/your particular game. Games often define a top-level concreteStates()\n\/\/*myGameState, []*myPlayerState so at the top of methods that accept a State\n\/\/they can quickly get concrete, type-checked types with only a single\n\/\/conversion leap of faith at the top. States are intended to be read-only;\n\/\/methods where you are allowed to mutate the state (e.g. Move.Apply()) will\n\/\/take a MutableState instead as a signal that it is permissable to modify the\n\/\/state. That is why the states only return non-mutable states\n\/\/(PropertyReaders, not PropertyReadSetters, although realistically it is\n\/\/possible to cast them and modify directly. The MarshalJSON output of a State\n\/\/is appropriate for sending to a client or serializing a state to be put in\n\/\/storage.

It provides a FUSE emulation layer which rclone\nuses combination with\n[cgofuse](https:\/\/github.com\/billziss-gh\/cgofuse).  Both of these\npackages are by Bill Zissimopoulos who was very helpful during the\nimplementation of rclone ` + commandName + ` for Windows.\n\n#### Windows caveats\n\nNote that drives created as Administrator are not visible by other\naccounts (including the account that was elevated as\nAdministrator). So if you start a Windows drive from an Administrative\nCommand Prompt and then try to access the same drive from Explorer\n(which does not run as Administrator), you will not be able to see the\nnew drive.\n\nThe easiest way around this is to start the drive from a normal\ncommand prompt. It is also possible to start a drive from the SYSTEM\naccount (using [the WinFsp.Launcher\ninfrastructure](https:\/\/github.com\/billziss-gh\/winfsp\/wiki\/WinFsp-Service-Architecture))\nwhich creates drives accessible for everyone on the system or\nalternatively using [the nssm service manager](https:\/\/nssm.cc\/usage).\n\n### Limitations\n\nWithout the use of \"--vfs-cache-mode\" this can only write files\nsequentially, it can only seek when reading.  This means that many\napplications won't work with their files on an rclone mount without\n\"--vfs-cache-mode writes\" or \"--vfs-cache-mode full\".  See the [File\nCaching](#file-caching) section for more info.\n\nThe bucket based remotes (eg Swift, S3, Google Compute Storage, B2,\nHubic) do not support the concept of empty directories, so empty\ndirectories will have a tendency to disappear once they fall out of\nthe directory cache.\n\nOnly supported on Linux, FreeBSD, OS X and Windows at the moment.\n\n### rclone ` + commandName + ` vs rclone sync\/copy\n\nFile systems expect things to be 100% reliable, whereas cloud storage\nsystems are a long way from 100% reliable. The rclone sync\/copy\ncommands cope with this with lots of retries.  However rclone ` + commandName + `\ncan't use retries in the same way without making local copies of the\nuploads. Look at the [file caching](#file-caching)\nfor solutions to make ` + commandName + ` more reliable.\n\n### Attribute caching\n\nYou can use the flag --attr-timeout to set the time the kernel caches\nthe attributes (size, modification time etc) for directory entries.\n\nThe default is \"1s\" which caches files just long enough to avoid\ntoo many callbacks to rclone from the kernel.\n\nIn theory 0s should be the correct value for filesystems which can\nchange outside the control of the kernel. However this causes quite a\nfew problems such as\n[rclone using too much memory](https:\/\/github.com\/rclone\/rclone\/issues\/2157),\n[rclone not serving files to samba](https:\/\/forum.rclone.org\/t\/rclone-1-39-vs-1-40-mount-issue\/5112)\nand [excessive time listing directories](https:\/\/github.com\/rclone\/rclone\/issues\/2095#issuecomment-371141147).\n\nThe kernel can cache the info about a file for the time given by\n\"--attr-timeout\". You may see corruption if the remote file changes\nlength during this window.  It will show up as either a truncated file\nor a file with garbage on the end.  With \"--attr-timeout 1s\" this is\nvery unlikely but not impossible.  The higher you set \"--attr-timeout\"\nthe more likely it is.  The default setting of \"1s\" is the lowest\nsetting which mitigates the problems above.\n\nIf you set it higher ('10s' or '1m' say) then the kernel will call\nback to rclone less often making it more efficient, however there is\nmore chance of the corruption issue above.\n\nIf files don't change on the remote outside of the control of rclone\nthen there is no chance of corruption.\n\nThis is the same as setting the attr_timeout option in mount.fuse.\n\n### Filters\n\nNote that all the rclone filters can be used to select a subset of the\nfiles to be visible in the mount.\n\n### systemd\n\nWhen running rclone ` + commandName + ` as a systemd service, it is possible\nto use Type=notify. In this case the service will enter the started state\nafter the mountpoint has been successfully set up.\nUnits having the rclone ` + commandName + ` service specified as a requirement\nwill see all files and folders immediately in this mode.\n\n### chunked reading ###\n\n--vfs-read-chunk-size will enable reading the source objects in parts.\nThis can reduce the used download quota for some remotes by requesting only chunks\nfrom the remote that are actually read at the cost of an increased number of requests.\n\nWhen --vfs-read-chunk-size-limit is also specified and greater than --vfs-read-chunk-size,\nthe chunk size for each open file will get doubled for each chunk read, until the\nspecified value is reached. A value of -1 will disable the limit and the chunk size will\ngrow indefinitely.\n\nWith --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following\nparts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on.\nWhen --vfs-read-chunk-size-limit 500M is specified, the result would be\n0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.\n\nChunked reading will only work with --vfs-cache-mode < full, as the file will always\nbe copied to the vfs cache before opening with --vfs-cache-mode full.\n` + vfs.Help,\n\t\tRun: func(command *cobra.Command, args []string) {\n\t\t\tcmd.CheckArgs(2, 2, command, args)\n\n\t\t\tif Daemon {\n\t\t\t\tconfig.PassConfigKeyForDaemonization = true\n\t\t\t}\n\n\t\t\tmountpoint := args[1]\n\t\t\tfdst := cmd.NewFsDir(args)\n\t\t\tif fdst.Name() == \"\" || fdst.Name() == \"local\" {\n\t\t\t\terr := checkMountpointOverlap(fdst.Root(), mountpoint)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t\t}\n\t\t\t}\n\n\t\t\t\/\/ Show stats if the user has specifically requested them\n\t\t\tif cmd.ShowStats() {\n\t\t\t\tdefer cmd.StartStats()()\n\t\t\t}\n\n\t\t\t\/\/ Skip checkMountEmpty if --allow-non-empty flag is used or if\n\t\t\t\/\/ the Operating System is Windows\n\t\t\tif !AllowNonEmpty && runtime.GOOS != \"windows\" {\n\t\t\t\terr := checkMountEmpty(mountpoint)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t\t}\n\t\t\t}\n\n\t\t\t\/\/ Work out the volume name, removing special\n\t\t\t\/\/ characters from it if necessary\n\t\t\tif VolumeName == \"\" {\n\t\t\t\tVolumeName = fdst.Name() + \":\" + fdst.Root()\n\t\t\t}\n\t\t\tVolumeName = strings.Replace(VolumeName, \":\", \" \", -1)\n\t\t\tVolumeName = strings.Replace(VolumeName, \"\/\", \" \", -1)\n\t\t\tVolumeName = strings.TrimSpace(VolumeName)\n\n\t\t\t\/\/ Start background task if --background is specified\n\t\t\tif Daemon {\n\t\t\t\tdaemonized := startBackgroundMode()\n\t\t\t\tif daemonized {\n\t\t\t\t\treturn\n\t\t\t\t}\n\t\t\t}\n\n\t\t\terr := Mount(fdst, mountpoint)\n\t\t\tif err != nil {\n\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t}\n\t\t},\n\t}\n\n\t\/\/ Register the command\n\tcmd.Root.AddCommand(commandDefintion)\n\n\t\/\/ Add flags\n\tflagSet := commandDefintion.Flags()\n\tflags.BoolVarP(flagSet, &DebugFUSE, \"debug-fuse\", \"\", DebugFUSE, \"Debug the FUSE internals - needs -v.\")\n\t\/\/ mount options\n\tflags.BoolVarP(flagSet, &AllowNonEmpty, \"allow-non-empty\", \"\", AllowNonEmpty, \"Allow mounting over a non-empty directory.\")\n\tflags.BoolVarP(flagSet, &AllowRoot, \"allow-root\", \"\", AllowRoot, \"Allow access to root user.\")\n\tflags.BoolVarP(flagSet, &AllowOther, \"allow-other\", \"\", AllowOther, \"Allow access to other users.\")\n\tflags.BoolVarP(flagSet, &DefaultPermissions, \"default-permissions\", \"\", DefaultPermissions, \"Makes kernel enforce access control based on the file mode.\")\n\tflags.BoolVarP(flagSet, &WritebackCache, \"write-back-cache\", \"\", WritebackCache, \"Makes kernel buffer writes before sending them to rclone.

It provides a FUSE emulation layer which rclone\nuses combination with\n[cgofuse](https:\/\/github.com\/billziss-gh\/cgofuse).  Both of these\npackages are by Bill Zissimopoulos who was very helpful during the\nimplementation of rclone ` + commandName + ` for Windows.\n\n#### Windows caveats\n\nNote that drives created as Administrator are not visible by other\naccounts (including the account that was elevated as\nAdministrator). So if you start a Windows drive from an Administrative\nCommand Prompt and then try to access the same drive from Explorer\n(which does not run as Administrator), you will not be able to see the\nnew drive.\n\nThe easiest way around this is to start the drive from a normal\ncommand prompt. It is also possible to start a drive from the SYSTEM\naccount (using [the WinFsp.Launcher\ninfrastructure](https:\/\/github.com\/billziss-gh\/winfsp\/wiki\/WinFsp-Service-Architecture))\nwhich creates drives accessible for everyone on the system or\nalternatively using [the nssm service manager](https:\/\/nssm.cc\/usage).\n\n### Limitations\n\nWithout the use of \"--vfs-cache-mode\" this can only write files\nsequentially, it can only seek when reading.  This means that many\napplications won't work with their files on an rclone mount without\n\"--vfs-cache-mode writes\" or \"--vfs-cache-mode full\".  See the [File\nCaching](#file-caching) section for more info.\n\nThe bucket based remotes (eg Swift, S3, Google Compute Storage, B2,\nHubic) do not support the concept of empty directories, so empty\ndirectories will have a tendency to disappear once they fall out of\nthe directory cache.\n\nOnly supported on Linux, FreeBSD, OS X and Windows at the moment.\n\n### rclone ` + commandName + ` vs rclone sync\/copy\n\nFile systems expect things to be 100% reliable, whereas cloud storage\nsystems are a long way from 100% reliable. The rclone sync\/copy\ncommands cope with this with lots of retries.  However rclone ` + commandName + `\ncan't use retries in the same way without making local copies of the\nuploads. Look at the [file caching](#file-caching)\nfor solutions to make ` + commandName + ` more reliable.\n\n### Attribute caching\n\nYou can use the flag --attr-timeout to set the time the kernel caches\nthe attributes (size, modification time etc) for directory entries.\n\nThe default is \"1s\" which caches files just long enough to avoid\ntoo many callbacks to rclone from the kernel.\n\nIn theory 0s should be the correct value for filesystems which can\nchange outside the control of the kernel. However this causes quite a\nfew problems such as\n[rclone using too much memory](https:\/\/github.com\/rclone\/rclone\/issues\/2157),\n[rclone not serving files to samba](https:\/\/forum.rclone.org\/t\/rclone-1-39-vs-1-40-mount-issue\/5112)\nand [excessive time listing directories](https:\/\/github.com\/rclone\/rclone\/issues\/2095#issuecomment-371141147).\n\nThe kernel can cache the info about a file for the time given by\n\"--attr-timeout\". You may see corruption if the remote file changes\nlength during this window.  It will show up as either a truncated file\nor a file with garbage on the end.  With \"--attr-timeout 1s\" this is\nvery unlikely but not impossible.  The higher you set \"--attr-timeout\"\nthe more likely it is.  The default setting of \"1s\" is the lowest\nsetting which mitigates the problems above.\n\nIf you set it higher ('10s' or '1m' say) then the kernel will call\nback to rclone less often making it more efficient, however there is\nmore chance of the corruption issue above.\n\nIf files don't change on the remote outside of the control of rclone\nthen there is no chance of corruption.\n\nThis is the same as setting the attr_timeout option in mount.fuse.\n\n### Filters\n\nNote that all the rclone filters can be used to select a subset of the\nfiles to be visible in the mount.\n\n### systemd\n\nWhen running rclone ` + commandName + ` as a systemd service, it is possible\nto use Type=notify. In this case the service will enter the started state\nafter the mountpoint has been successfully set up.\nUnits having the rclone ` + commandName + ` service specified as a requirement\nwill see all files and folders immediately in this mode.\n\n### chunked reading ###\n\n--vfs-read-chunk-size will enable reading the source objects in parts.\nThis can reduce the used download quota for some remotes by requesting only chunks\nfrom the remote that are actually read at the cost of an increased number of requests.\n\nWhen --vfs-read-chunk-size-limit is also specified and greater than --vfs-read-chunk-size,\nthe chunk size for each open file will get doubled for each chunk read, until the\nspecified value is reached. A value of -1 will disable the limit and the chunk size will\ngrow indefinitely.\n\nWith --vfs-read-chunk-size 100M and --vfs-read-chunk-size-limit 0 the following\nparts will be downloaded: 0-100M, 100M-200M, 200M-300M, 300M-400M and so on.\nWhen --vfs-read-chunk-size-limit 500M is specified, the result would be\n0-100M, 100M-300M, 300M-700M, 700M-1200M, 1200M-1700M and so on.\n\nChunked reading will only work with --vfs-cache-mode < full, as the file will always\nbe copied to the vfs cache before opening with --vfs-cache-mode full.\n` + vfs.Help,\n\t\tRun: func(command *cobra.Command, args []string) {\n\t\t\tcmd.CheckArgs(2, 2, command, args)\n\n\t\t\tif Daemon {\n\t\t\t\tconfig.PassConfigKeyForDaemonization = true\n\t\t\t}\n\n\t\t\tmountpoint := args[1]\n\t\t\tfdst := cmd.NewFsDir(args)\n\t\t\tif fdst.Name() == \"\" || fdst.Name() == \"local\" {\n\t\t\t\terr := checkMountpointOverlap(fdst.Root(), mountpoint)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t\t}\n\t\t\t}\n\n\t\t\t\/\/ Show stats if the user has specifically requested them\n\t\t\tif cmd.ShowStats() {\n\t\t\t\tdefer cmd.StartStats()()\n\t\t\t}\n\n\t\t\t\/\/ Skip checkMountEmpty if --allow-non-empty flag is used or if\n\t\t\t\/\/ the Operating System is Windows\n\t\t\tif !AllowNonEmpty && runtime.GOOS != \"windows\" {\n\t\t\t\terr := checkMountEmpty(mountpoint)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t\t}\n\t\t\t}\n\n\t\t\t\/\/ Work out the volume name, removing special\n\t\t\t\/\/ characters from it if necessary\n\t\t\tif VolumeName == \"\" {\n\t\t\t\tVolumeName = fdst.Name() + \":\" + fdst.Root()\n\t\t\t}\n\t\t\tVolumeName = strings.Replace(VolumeName, \":\", \" \", -1)\n\t\t\tVolumeName = strings.Replace(VolumeName, \"\/\", \" \", -1)\n\t\t\tVolumeName = strings.TrimSpace(VolumeName)\n\n\t\t\t\/\/ Start background task if --background is specified\n\t\t\tif Daemon {\n\t\t\t\tdaemonized := startBackgroundMode()\n\t\t\t\tif daemonized {\n\t\t\t\t\treturn\n\t\t\t\t}\n\t\t\t}\n\n\t\t\terr := Mount(fdst, mountpoint)\n\t\t\tif err != nil {\n\t\t\t\tlog.Fatalf(\"Fatal error: %v\", err)\n\t\t\t}\n\t\t},\n\t}\n\n\t\/\/ Register the command\n\tcmd.Root.AddCommand(commandDefintion)\n\n\t\/\/ Add flags\n\tflagSet := commandDefintion.Flags()\n\tflags.BoolVarP(flagSet, &DebugFUSE, \"debug-fuse\", \"\", DebugFUSE, \"Debug the FUSE internals - needs -v.\")\n\t\/\/ mount options\n\tflags.BoolVarP(flagSet, &AllowNonEmpty, \"allow-non-empty\", \"\", AllowNonEmpty, \"Allow mounting over a non-empty directory.\")\n\tflags.BoolVarP(flagSet, &AllowRoot, \"allow-root\", \"\", AllowRoot, \"Allow access to root user.\")\n\tflags.BoolVarP(flagSet, &AllowOther, \"allow-other\", \"\", AllowOther, \"Allow access to other users.\")\n\tflags.BoolVarP(flagSet, &DefaultPermissions, \"default-permissions\", \"\", DefaultPermissions, \"Makes kernel enforce access control based on the file mode.\")\n\tflags.BoolVarP(flagSet, &WritebackCache, \"write-back-cache\", \"\", WritebackCache, \"Makes kernel buffer writes before sending them to rclone.

I will use VLI to compare all digits of the hashes.\n  23 Apr 13 -- Fixed problem of a single line in the hashes file, that does not contain an EOL character, causes\n                an immediate return without processing of the characters just read in.\n  24 Apr 13 -- Added output of which file either matches or does not match.\n  19 Sep 16 -- Finished conversion to Go, that was started 13 Sep 16.  Added the removed of '*' which is part of a std linux formated hash file.  And I forgot that\n                 the routine allowed either order in the file.  If the token has a '.' I assume it is a filename, else it is a hash value.\n  21 Sep 16 -- Fixed the case issue in tokenize.GetToken.  Edited code here to correspond to this fix.\n  25 Nov 16 -- Need to not panic when target file is not found, only panic when hash file is not found.\n                 And added a LastCompiled message and string.\n  13 Oct 17 -- No changes here, but tokenize was changed so that horizontal tab char is now a delim.\n  14 Oct 17 -- Tweaked output a bit.  And added executable timestamp code.\n  19 Oct 17 -- Added ability to ignore the * that standard hash files for linux use.\n  22 Oct 17 -- Added filepicker.\n  21 Jan 18 -- Really ignore *.  Before method did not work.\n  26 Jan 18 -- Changed tokenize so that SetMapDelim change sticks and actually works.\n  13 Nov 18 -- Will use \"-\" and \"_\" also to detect a filename token.\n  10 Nov 19 -- Now uses ToLower to compare the string hashes, to ignore case.\n  15 Jul 20 -- Decided to make better guesses.  Sha1 has 40 digits, Sha256 has 64 digits and Sha512 has 128 digits.\n  27 Sep 20 -- From help file of TakeCommand: MD-5 has 32 digits, SHA384 has 96 digits, and the above hash lengths are correct.\n                 And I'm going to change from tokenize to tknptr.  Just to see if it works.\n  25 Feb 21 -- Added 999 as a stop code.\n   3 Mar 21 -- Now called sha.go, which will always use hash length, while ignoring file extension.\n                 Errors now go to Stderr.  Uses bytes buffer to read sha file using io.ReadAll. and go 1.15.8\n   7 Mar 21 -- added strings.TrimSpace\n   8 Apr 21 -- Converted import list to module named src.  So essentially, very little has changed except for these import statements.\n  13 Feb 22 -- filepicker API changed recently.

I will use VLI to compare all digits of the hashes.\n  23 Apr 13 -- Fixed problem of a single line in the hashes file, that does not contain an EOL character, causes\n                an immediate return without processing of the characters just read in.\n  24 Apr 13 -- Added output of which file either matches or does not match.\n  19 Sep 16 -- Finished conversion to Go, that was started 13 Sep 16.  Added the removal of '*' which is part of a std linux formatted hash file.  And I forgot that\n                 the routine allowed either order in the file.  If the token has a '.' I assume it is a filename, else it is a hash value.\n  21 Sep 16 -- Fixed the case issue in tokenize.GetToken.  Edited code here to correspond to this fix.\n  25 Nov 16 -- Need to not panic when target file is not found, only panic when hash file is not found.\n                 And added a LastCompiled message and string.\n  13 Oct 17 -- No changes here, but tokenize was changed so that horizontal tab char is now a delim.\n  14 Oct 17 -- Tweaked output a bit.  And added executable timestamp code.\n  19 Oct 17 -- Added ability to ignore the * that standard hash files for linux use.\n  22 Oct 17 -- Added filepicker.\n  21 Jan 18 -- Really ignore *.  Before method did not work.\n  26 Jan 18 -- Changed tokenize so that SetMapDelim change sticks and actually works.\n  13 Nov 18 -- Will use \"-\" and \"_\" also to detect a filename token.\n  10 Nov 19 -- Now uses ToLower to compare the string hashes, to ignore case.\n  15 Jul 20 -- Decided to make better guesses.  Sha1 has 40 digits, Sha256 has 64 digits and Sha512 has 128 digits.\n  27 Sep 20 -- From help file of TakeCommand: MD-5 has 32 digits, SHA384 has 96 digits, and the above hash lengths are correct.\n                 And I'm going to change from tokenize to tknptr.  Just to see if it works.\n  25 Feb 21 -- Added 999 as a stop code.\n   3 Mar 21 -- Now called sha.go, which will always use hash length, while ignoring file extension.\n                 Errors now go to Stderr.  Uses bytes buffer to read sha file using io.ReadAll. and go 1.15.8\n   7 Mar 21 -- added strings.TrimSpace\n   8 Apr 21 -- Converted import list to module named src.  So essentially, very little has changed except for these import statements.\n  13 Feb 22 -- filepicker API changed recently.  So I'm updating the code here that uses filepicker.\n   9 Mar 22 -- Using package constants instead of my magic numbers.\n*\/\n\nconst LastCompiled = \"9 Mar 2022\"\n\n\/\/* ************************* MAIN ***************************************************************\nfunc main() {\n\n\tconst K = 1024\n\tconst M = 1024 * 1024\n\n\tconst (\n\t\tundetermined = iota\n\t\tmd5hash\n\t\tsha1hash\n\t\tsha256hash\n\t\tsha384hash\n\t\tsha512hash\n\t)\n\n\tconst ReadBufferSize = M\n\n\tvar HashName = [...]string{\"undetermined\", \"md5\", \"sha1\", \"sha256\", \"sha384\", \"sha512\"}\n\tvar ans, Filename string\n\tvar WhichHash int\n\tvar TargetFilename, HashValueReadFromFile, HashValueComputedStr string\n\tvar hasher hash.Hash\n\tvar FileSize int64\n\n\tfmt.Print(\" sha.go.

If that happens, we continue down\n\/\/ the rabbit hole during the execution of f.\n\/\/\n\/\/ To make it possible for gcc-compiled C code to call a Go function p.GoF,\n\/\/ cgo writes a gcc-compiled function named GoF (not p.GoF, since gcc doesn't\n\/\/ know about packages).  The gcc-compiled C function f calls GoF.\n\/\/\n\/\/ GoF calls crosscall2(_cgoexp_GoF, frame, framesize).  Crosscall2\n\/\/ (in cgo\/gcc_$GOARCH.S, a gcc-compiled assembly file) is a two-argument\n\/\/ adapter from the gcc function call ABI to the 6c function call ABI.\n\/\/ It is called from gcc to call 6c functions.  In this case it calls\n\/\/ _cgoexp_GoF(frame, framesize), still running on m->g0's stack\n\/\/ and outside the $GOMAXPROCS limit.  Thus, this code cannot yet\n\/\/ call arbitrary Go code directly and must be careful not to allocate\n\/\/ memory or use up m->g0's stack.\n\/\/\n\/\/ _cgoexp_GoF calls runtime.cgocallback(p.GoF, frame, framesize).\n\/\/ (The reason for having _cgoexp_GoF instead of writing a crosscall3\n\/\/ to make this call directly is that _cgoexp_GoF, because it is compiled\n\/\/ with 6c instead of gcc, can refer to dotted names like\n\/\/ runtime.cgocallback and p.GoF.)\n\/\/\n\/\/ runtime.cgocallback (in asm_$GOARCH.s) switches from m->g0's\n\/\/ stack to the original g (m->curg)'s stack, on which it calls\n\/\/ runtime.cgocallbackg(p.GoF, frame, framesize).\n\/\/ As part of the stack switch, runtime.cgocallback saves the current\n\/\/ SP as m->g0->sched.sp, so that any use of m->g0's stack during the\n\/\/ execution of the callback will be done below the existing stack frames.\n\/\/ Before overwriting m->g0->sched.sp, it pushes the old value on the\n\/\/ m->g0 stack, so that it can be restored later.\n\/\/\n\/\/ runtime.cgocallbackg (below) is now running on a real goroutine\n\/\/ stack (not an m->g0 stack).  First it calls runtime.exitsyscall, which will\n\/\/ block until the $GOMAXPROCS limit allows running this goroutine.\n\/\/ Once exitsyscall has returned, it is safe to do things like call the memory\n\/\/ allocator or invoke the Go callback function p.GoF.  runtime.cgocallbackg\n\/\/ first defers a function to unwind m->g0.sched.sp, so that if p.GoF\n\/\/ panics, m->g0.sched.sp will be restored to its old value: the m->g0 stack\n\/\/ and the m->curg stack will be unwound in lock step.\n\/\/ Then it calls p.GoF.  Finally it pops but does not execute the deferred\n\/\/ function, calls runtime.entersyscall, and returns to runtime.cgocallback.\n\/\/\n\/\/ After it regains control, runtime.cgocallback switches back to\n\/\/ m->g0's stack (the pointer is still in m->g0.sched.sp), restores the old\n\/\/ m->g0.sched.sp value from the stack, and returns to _cgoexp_GoF.\n\/\/\n\/\/ _cgoexp_GoF immediately returns to crosscall2, which restores the\n\/\/ callee-save registers for gcc and returns to GoF, which returns to f.\n\npackage runtime\n\nimport \"unsafe\"\n\n\/\/ Call from Go to C.\n\/\/go:nosplit\nfunc cgocall(fn, arg unsafe.Pointer) {\n\tcgocall_errno(fn, arg)\n}\n\n\/\/go:nosplit\nfunc cgocall_errno(fn, arg unsafe.Pointer) int32 {\n\tif !iscgo && GOOS != \"solaris\" && GOOS != \"windows\" {\n\t\tgothrow(\"cgocall unavailable\")\n\t}\n\n\tif fn == nil {\n\t\tgothrow(\"cgocall nil\")\n\t}\n\n\tif raceenabled {\n\t\tracereleasemerge(unsafe.Pointer(&racecgosync))\n\t}\n\n\t\/\/ Create an extra M for callbacks on threads not created by Go on first cgo call.\n\tif needextram == 1 && cas(&needextram, 1, 0) {\n\t\tonM(newextram)\n\t}\n\n\t\/*\n\t * Lock g to m to ensure we stay on the same stack if we do a\n\t * cgo callback.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage gorilla\/sessions provides cookie sessions and infrastructure for\ncustom session backends.\n\nThe key features are:\n\n* Dead simple basic API: use it as an easy way to set signed (and optionally\nencrypted) cookies.\n\n* Advanced API for custom backends: built-in support for custom storage\nsystems; session store interface and helper functions; encoder interface\nand default implementation with customizable cryptography methods (thanks to\nGo interfaces).\n\n* Conveniences: flash messages (session values that last until read);\nbuilt-in mechanism to rotate authentication and encryption keys;\nmultiple sessions per request, even using different backends; easy way to\nswitch session persistency (aka \"remember me\") and set other attributes.\n\nThe most basic example to retrieve a session is to call sessions.Session()\npassing the current request. For example, in a handler:\n\n\tfunc MyHandler(w http.ResponseWriter, r *http.Request) {\n\t\tif session, err := sessions.Session(r); err == nil {\n\t\t\tsession[\"foo\"] = \"bar\"\n\t\t\tsession[\"baz\"] = 128\n\t\t\tsessions.Save(r, w)\n\t\t}\n\t}\n\nThe above snippet is \"gorilla\/sessions in a nutshell\": a session is a simple\nmap[string]interface{} returned from sessions.Session(). It stores any values\nthat can be encoded using gob. After we set some values, we call\nsessions.Save() passing the current request and response.\n\nSide note about \"any values that can be encoded using gob\": to store special\nstructures in a session, we must register them using gob.Register() first.\nFor basic types this is not needed; it works out of the box.\n\nIs it that simple? Well, almost. Before we can use sessions, we must define\na secret key to be used for authentication, and optionally an encryption key.\nThey are both set calling SetStoreKeys() and should be done at initialization\ntime:\n\n\tfunc init() {\n\t\tsessions.SetStoreKeys(\"cookie\",\n\t\t\t\t\t\t\t  []byte(\"my-hmac-key\"),\n\t\t\t\t\t\t\t  []byte(\"my-aes-key\"))\n\t}\n\nThe first argument is the name used to register the session store. By default\na \"cookie\" store is registered and available for use, so we use that name.\n\nThe second argument is the secret key used to authenticate the session cookie\nusing HMAC. It is required; if no authentication key is set sessions can't be\nread or written (and a call to sessions.Session() will return an error).\n\nThe third argument is the encryption key; it is optional and can be omitted.\nFor the cookie store, setting this will encrypt the contents stored in the\ncookie; otherwise the contents can be read, although not forged.\n\nSide note about the encryption key: if set, must be either 16, 24, or 32 bytes\nto select AES-128, AES-192, or AES-256 modes. Otherwise a block can't be\ncreated and sessions won't work.\n\nExposing the contents of a session is not a big deal in many cases, like when\nwe store a simple username or user id, but to to store sensitive information\nusing the cookie store, we must set an encryption key. For custom stores that\nonly set a random session id in the cookie, encryption is not needed.\n\nAnd this is all you need to know about the basic usage. More advanced options\nare explained below.\n\nSometimes we may want to change authentication and\/or encryption keys without\nbreaking existing sessions. We can do this setting multiple authentication and\nencryption keys, in pairs, to be tested in order:\n\n\tsessions.SetStoreKeys(\"cookie\",\n\t\t\t\t\t\t  []byte(\"my-hmac-key\"),\n\t\t\t\t\t\t  []byte(\"my-aes-key\"),\n\t\t\t\t\t\t  []byte(\"my-previous-hmac-key\"),\n\t\t\t\t\t\t  []byte(\"my-previous-aes-key\"))\n\nNew sessions will be saved using the first pair. Old sessions can still be\nread because the first pair will fail, and the second will be tested. This\nmakes it easy to \"rotate\" secret keys and still be able to validate existing\nsessions. Note: for all pairs the encryption key is optional; set it\nto nil and encryption won't be used.\n\nBack to how sessions are retrieved.\n\nSessions are named. When we get a session calling sessions.Session(request),\nwe are implicitly requesting a session using the default key (\"s\") and store\n(the CookieSessionStore). This is just a convenience; we can have as many\nsessions as needed, just passing different session keys. For example:\n\n\tif authSession, err := sessions.Session(r, \"auth\"); err == nil {\n\t\tuserId = authSession[\"userId\"]\n\t\t\/\/ ...\n\t}\n\nHere we requested a session explicitly naming it \"auth\". It will be saved\nseparately. This can be used as a convenient way to save signed cookies, and\nis also how we access multiple sessions per request.\n\nSession stores also have a name, and need to be registered to be available.\nThe default session store uses authenticated (and optionally encrypted)\ncookies, and is registered with the name \"cookie\". To use a custom\nsession backend, we first register it in the SessionFactory, then pass its\nname as the third argument to sessions.Session().\n\nFor the sake of demonstration, let's pretend that we defined a store called\nMemcacheSessionStore. First we register it using the \"memcache\" key. This\nshould be done at initialization time:\n\n\tfunc init() {\n\t\tsessions.SetStore(\"memcache\", new(MemcacheSessionStore))\n\t}\n\nThen to get a session using memcached, we pass a third argument to\nsessions.Session(), the store key:\n\n\tsession, err := sessions.Session(r, \"mysession\", \"memcache\")\n\n...and it will use the custom backend we defined, instead of the default\n\"cookie\" one. This means that we can use multiple sessions in the same\nrequest even using different backends.\n\nAnd how to configure session expiration time, path or other cookie attributes?\n\nBy default, session cookies last for a month. This is probably too long for a\nlot of cases, but it is easy to change this and other attributes during\nruntime. Just request the session configuration struct and change the variables\nas needed. The fields are basically a subset of http.Cookie fields.\nTo change MaxAge, we would do:\n\n\tif config, err = sessions.Config(r); err == nil {\n\t\t\/\/ Change max-age to 1 week.\n\t\tconfig.MaxAge = 86400 * 7\n\t}\n\nAfter this, cookies will last for a week only. The Config() function\naccepts an optional argument besides the request: the session key. If not\ndefined, the configuration for the default session key is returned.\n\nBonus: flash messages. What are they? It basically means \"session values that\nlast until read\". The term was popularized by Ruby On Rails a few years back.\nWhen we request a flash message, it is removed from the session. We have two\nconvenience functions to read and set them: Flashes() and AddFlash(). Here is\nan example:\n\n\tfunc MyHandler(w http.ResponseWriter, r *http.Request) {\n\t\t\/\/ Get the previously set flashes, if any.\n\t\tif flashes, _ := sessions.Flashes(r); flashes != nil {\n\t\t\t\/\/ Just print the flash values.\n\t\t\tfmt.Fprint(w, \"%v\", flashes)\n\t\t} else {\n\t\t\tfmt.Fprint(w, \"No flashes found.\")\n\t\t\t\/\/ Set a new flash.\n\t\t\tsessions.AddFlash(r, \"Hello, flash messages world!\")\n\t\t}\n\t\tsessions.Save(r, w)\n\t}\n\nFlash messages are useful to set information to be read after a redirection,\nusually after form submissions.\n\nAnd that's it.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage gorilla\/sessions provides cookie sessions and infrastructure for\ncustom session backends.\n\nThe key features are:\n\n* Dead simple basic API: use it as an easy way to set signed (and optionally\nencrypted) cookies.\n\n* Advanced API for custom backends: built-in support for custom storage\nsystems; session store interface and helper functions; encoder interface\nand default implementation with customizable cryptography methods (thanks to\nGo interfaces).\n\n* Conveniences: flash messages (session values that last until read);\nbuilt-in mechanism to rotate authentication and encryption keys;\nmultiple sessions per request, even using different backends; easy way to\nswitch session persistency (aka \"remember me\") and set other attributes.\n\nThe most basic example to retrieve a session is to call sessions.Session()\npassing the current request. For example, in a handler:\n\n\tfunc MyHandler(w http.ResponseWriter, r *http.Request) {\n\t\tif session, err := sessions.Session(r); err == nil {\n\t\t\tsession[\"foo\"] = \"bar\"\n\t\t\tsession[\"baz\"] = 128\n\t\t\tsessions.Save(r, w)\n\t\t}\n\t}\n\nThe above snippet is \"gorilla\/sessions in a nutshell\": a session is a simple\nmap[string]interface{} returned from sessions.Session(). It stores any values\nthat can be encoded using gob. After we set some values, we call\nsessions.Save() passing the current request and response.\n\nSide note about \"any values that can be encoded using gob\": to store special\nstructures in a session, we must register them using gob.Register() first.\nFor basic types this is not needed; it works out of the box.\n\nIs it that simple? Well, almost. Before we can use sessions, we must define\na secret key to be used for authentication, and optionally an encryption key.\nThey are both set calling SetStoreKeys() and should be done at initialization\ntime:\n\n\tfunc init() {\n\t\tsessions.SetStoreKeys(\"cookie\",\n\t\t\t\t\t\t\t  []byte(\"my-hmac-key\"),\n\t\t\t\t\t\t\t  []byte(\"my-aes-key\"))\n\t}\n\nThe first argument is the name used to register the session store. By default\na \"cookie\" store is registered and available for use, so we use that name.\n\nThe second argument is the secret key used to authenticate the session cookie\nusing HMAC. It is required; if no authentication key is set sessions can't be\nread or written (and a call to sessions.Session() will return an error).\n\nThe third argument is the encryption key; it is optional and can be omitted.\nFor the cookie store, setting this will encrypt the contents stored in the\ncookie; otherwise the contents can be read, although not forged.\n\nSide note about the encryption key: if set, must be either 16, 24, or 32 bytes\nto select AES-128, AES-192, or AES-256 modes. Otherwise a block can't be\ncreated and sessions won't work.\n\nExposing the contents of a session is not a big deal in many cases, like when\nwe store a simple username or user id, but to to store sensitive information\nusing the cookie store, we must set an encryption key. For custom stores that\nonly set a random session id in the cookie, encryption is not needed.\n\nAnd this is all you need to know about the basic usage. More advanced options\nare explained below.\n\nSometimes we may want to change authentication and\/or encryption keys without\nbreaking existing sessions. We can do this setting multiple authentication and\nencryption keys, in pairs, to be tested in order:\n\n\tsessions.SetStoreKeys(\"cookie\",\n\t\t\t\t\t\t  []byte(\"my-hmac-key\"),\n\t\t\t\t\t\t  []byte(\"my-aes-key\"),\n\t\t\t\t\t\t  []byte(\"my-previous-hmac-key\"),\n\t\t\t\t\t\t  []byte(\"my-previous-aes-key\"))\n\nNew sessions will be saved using the first pair. Old sessions can still be\nread because the first pair will fail, and the second will be tested. This\nmakes it easy to \"rotate\" secret keys and still be able to validate existing\nsessions. Note: for all pairs the encryption key is optional; set it\nto nil and encryption won't be used.\n\nBack to how sessions are retrieved.\n\nSessions are named. When we get a session calling sessions.Session(request),\nwe are implicitly requesting a session using the default key (\"s\") and store\n(the CookieSessionStore). This is just a convenience; we can have as many\nsessions as needed, just passing different session keys. For example:\n\n\tif authSession, err := sessions.Session(r, \"auth\"); err == nil {\n\t\tuserId = authSession[\"userId\"]\n\t\t\/\/ ...\n\t}\n\nHere we requested a session explicitly naming it \"auth\". It will be saved\nseparately. This can be used as a convenient way to save signed cookies, and\nis also how we access multiple sessions per request.\n\nSession stores also have a name, and need to be registered to be available.\nThe default session store uses authenticated (and optionally encrypted)\ncookies, and is registered with the name \"cookie\". To use a custom\nsession backend, we first register it in the SessionFactory, then pass its\nname as the third argument to sessions.Session().\n\nFor the sake of demonstration, let's pretend that we defined a store called\nMemcacheSessionStore. First we register it using the \"memcache\" key. This\nshould be done at initialization time:\n\n\tfunc init() {\n\t\tsessions.SetStore(\"memcache\", new(MemcacheSessionStore))\n\t}\n\nThen to get a session using memcached, we pass a third argument to\nsessions.Session(), the store key:\n\n\tsession, err := sessions.Session(r, \"mysession\", \"memcache\")\n\n...and it will use the custom backend we defined, instead of the default\n\"cookie\" one. This means that we can use multiple sessions in the same\nrequest even using different backends.\n\nAnd how to configure session expiration time, path or other cookie attributes?\n\nBy default, session cookies last for a month. This is probably too long for a\nlot of cases, but it is easy to change this and other attributes during\nruntime. Just request the session configuration struct and change the variables\nas needed. The fields are basically a subset of http.Cookie fields.\nTo change MaxAge, we would do:\n\n\tif config, err = sessions.Config(r); err == nil {\n\t\t\/\/ Change max-age to 1 week.\n\t\tconfig.MaxAge = 86400 * 7\n\t}\n\nAfter this, cookies will last for a week only. The Config() function\naccepts an optional argument besides the request: the session key. If not\ndefined, the configuration for the default session key is returned.\n\nBonus: flash messages. What are they? It basically means \"session values that\nlast until read\". The term was popularized by Ruby On Rails a few years back.\nWhen we request a flash message, it is removed from the session. We have two\nconvenience functions to read and set them: Flashes() and AddFlash(). Here is\nan example:\n\n\tfunc MyHandler(w http.ResponseWriter, r *http.Request) {\n\t\t\/\/ Get the previously set flashes, if any.\n\t\tif flashes, _ := sessions.Flashes(r); flashes != nil {\n\t\t\t\/\/ Just print the flash values.\n\t\t\tfmt.Fprint(w, \"%v\", flashes)\n\t\t} else {\n\t\t\tfmt.Fprint(w, \"No flashes found.\")\n\t\t\t\/\/ Set a new flash.\n\t\t\tsessions.AddFlash(r, \"Hello, flash messages world!\")\n\t\t}\n\t\tsessions.Save(r, w)\n\t}\n\nFlash messages are useful to set information to be read after a redirection,\nusually after form submissions.\n*\/\npackage sessions\n<|endoftext|>"}

{"text":"<commit_before>\/\/ The `mongo` plugin for SHIELD implements generic backup + restore\n\/\/ functionality for mongodb.

Your endpoint JSON\n\/\/ should look something like this:\n\/\/\n\/\/    {\n\/\/        \"mongo_host\"     : \"127.0.0.1\",   # optional\n\/\/        \"mongo_port\"     : \"27017\",       # optional\n\/\/        \"mongo_user\"     : \"username\",    # optional\n\/\/        \"mongo_password\" : \"password\",    # optional\n\/\/        \"mongo_database\" : \"db\",          # optional\n\/\/        \"mongo_bindir\"   : \"\/path\/to\/bin\" # optional\n\/\/    }\n\/\/\n\/\/ BACKUP DETAILS\n\/\/\n\/\/ If `mongo_database` is specified in the plugin configuration, the `mongo` plugin backs up ONLY\n\/\/ the specified database using `mongodump` command.\n\/\/ If `mongo_database` is not specified, all databases are backed up.\n\/\/\n\/\/ Backing up with the `mongo` plugin will not drop any existing connections to the database,\n\/\/ or restart the service.\n\/\/\n\/\/\n\/\/RESTORE DETAILS\n\/\/\n\/\/ To restore, the `mongo` plugin connects to the mongodb server using the `mongorestore` command.\n\/\/ It then feeds in the backup data (`mongodump` output). Unlike the the `postgres` plugin,\n\/\/ this plugin does NOT need to disconnect any open connections to mongodb to perform the\n\/\/ restoration.\n\/\/\n\/\/ Restoring with the `mongo` plugin should not interrupt established connections to the service.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ This plugin relies on the `mongodump` and `mongorestore` utilities.

Your endpoint JSON\n\/\/ should look something like this:\n\/\/\n\/\/    {\n\/\/        \"mongo_host\"     : \"127.0.0.1\",   # optional\n\/\/        \"mongo_port\"     : \"27017\",       # optional\n\/\/        \"mongo_user\"     : \"username\",    # optional\n\/\/        \"mongo_password\" : \"password\",    # optional\n\/\/        \"mongo_database\" : \"db\",          # optional\n\/\/        \"mongo_bindir\"   : \"\/path\/to\/bin\" # optional\n\/\/    }\n\/\/\n\/\/ BACKUP DETAILS\n\/\/\n\/\/ If `mongo_database` is specified in the plugin configuration, the `mongo` plugin backs up ONLY\n\/\/ the specified database using `mongodump` command.\n\/\/ If `mongo_database` is not specified, all databases are backed up.\n\/\/\n\/\/ Backing up with the `mongo` plugin will not drop any existing connections to the database,\n\/\/ or restart the service.\n\/\/\n\/\/\n\/\/RESTORE DETAILS\n\/\/\n\/\/ To restore, the `mongo` plugin connects to the mongodb server using the `mongorestore` command.\n\/\/ It then feeds in the backup data (`mongodump` output). Unlike the the `postgres` plugin,\n\/\/ this plugin does NOT need to disconnect any open connections to mongodb to perform the\n\/\/ restoration.\n\/\/\n\/\/ Restoring with the `mongo` plugin should not interrupt established connections to the service.\n\/\/\n\/\/ DEPENDENCIES\n\/\/\n\/\/ This plugin relies on the `mongodump` and `mongorestore` utilities. Please ensure\n\/\/ that they are present on the system that will be running the backups + restores\n\/\/ for mongodb.\n\n\/\/ TODO: add agent-mongodb job template to shield-boshrelease\n\/\/ If you are using shield-boshrelease to deploy SHIELD, these tools\n\/\/ are provided so long as you include the `agent-mongodb` job template along side\n\/\/ your `shield agent`.\n\/\/\npackage
