The values available in the data file are then used to render the\n    template file and generate output.\n\n    By default, jgtr reads the data and template from stdin, and writes output\n    to stdout. Note that data and template cannot both come from stdin - at\n    least one of the two must be specified via an option.\n\n    jgtr can consume data from JSON, YAML 1.1 or TOML v0.2.0. You can specify\n    which type to use via an option. If no such option is given, jgtr attempts\n    to guess from the extension of the data file (if any). If the format is\n    still ambiguous, jgtr uses JSON as the default.\n\nOPTIONS:\n    -d FILE, --data=FILE\n        Read data data from FILE.

That's working, but I had to\n             import more parts of fyne.io than the unmodified version.\n12 Aug 21 -- Now called img.go, so I can display 1 image.  I'll start here.\n13 Aug 21 -- Now called imgfyne.go.  Same purpose as img.go, but so I can test non-fyne code there and fyne code here.\n15 Aug 21 -- Copied back to img.go after the code works and displays a single image from the command line.\n               Will use imgfyne to add the arrow key navigation and img display.\n18 Aug 21 -- It works!\n20 Aug 21 -- Adding a verbose switch to print the messages, and not print them unless that switch is

I believe it will be enhanced in later chapters, but this is what is it for now.\n\/*\nREVISION HISTORY\n-------- -------\n 9 Aug 21 -- I realized that this will not be enhanced, as I went thru more of the book.  I'll have to enhance it myself.\n             First, I'm changing the function constants to the version that's more readable to me.  That's working, but I had to\n             import more parts of fyne.io than the unmodified version.\n12 Aug 21 -- Now called img.go, so I can display 1 image.  I'll start here.\n13 Aug 21 -- Now called imgfyne.go.  Same purpose as img.go, but so I can test non-fyne code there and fyne code here.\n15 Aug 21 -- Copied back to img.go after the code works and displays a single image from the command line.\n               Will use imgfyne to add the arrow key navigation and img display.\n18 Aug 21 -- It works!\n20 Aug 21 -- Adding a verbose switch to print the messages, and not print them unless that switch is used.\n21 Aug 21 -- Adding Q and X to exit.\n*\/\n\npackage main\n\nimport (\n\t\"flag\"\n\t\"fmt\"\n\t\"fyne.io\/fyne\/v2\/app\"\n\t\/\/w

These behave like Go's untyped\n\t  constants, although raw strings may not span newlines.\n\t- The keyword nil, representing an untyped Go nil.\n\t- The character '.' (period):\n\t\t.\n\t  The result is the value of dot.\n\t- A variable name, which is a (possibly empty) alphanumeric string\n\t  preceded by a dollar sign, such as\n\t\t$piOver2\n\t  or\n\t\t$\n\t  The result is the value of the variable.\n\t  Variables are described below.\n\t- The name of a field of the data, which must be a struct, preceded\n\t  by a period, such as\n\t\t.Field\n\t  The result is the value of the field. Field invocations may be\n\t  chained:\n\t    .Field1.Field2\n\t  Fields can also be evaluated on variables, including chaining:\n\t    $x.Field1.Field2\n\t- The name of a key of the data, which must be a map, preceded\n\t  by a period, such as\n\t\t.Key\n\t  The result is the map element value indexed by the key.\n\t  Key invocations may be chained and combined with fields to any\n\t  depth:\n\t    .Field1.Key1.Field2.Key2\n\t  Although the key must be an alphanumeric identifier, unlike with\n\t  field names they do not need to start with an upper case letter.\n\t  Keys can also be evaluated on variables, including chaining:\n\t    $x.key1.key2\n\t- The name of a niladic method of the data, preceded by a period,\n\t  such as\n\t\t.Method\n\t  The result is the value of invoking the method with dot as the\n\t  receiver, dot.Method(). Such a method must have one return value (of\n\t  any type) or two return values, the second of which is an error.\n\t  If it has two and the returned error is non-nil, execution terminates\n\t  and an error is returned to the caller as the value of Execute.\n\t  Method invocations may be chained and combined with fields and keys\n\t  to any depth:\n\t    .Field1.Key1.Method1.Field2.Key2.Method2\n\t  Methods can also be evaluated on variables, including chaining:\n\t    $x.Method1.Field\n\t- The name of a niladic function, such as\n\t\tfun\n\t  The result is the value of invoking the function, fun(). The return\n\t  types and values behave as in methods. Functions and function\n\t  names are described below.\n\t- A parenthesized instance of one the above, for grouping. The result\n\t  may be accessed by a field or map key invocation.\n\t\tprint (.F1 arg1) (.F2 arg2)\n\t\t(.StructValuedMethod \"arg\").Field\n\nArguments may evaluate to any type; if they are pointers the implementation\nautomatically indirects to the base type when required.\nIf an evaluation yields a function value, such as a function-valued\nfield of a struct, the function is not invoked automatically, but it\ncan be used as a truth value for an if action and the like. To invoke\nit, use the call function, defined below.\n\nA pipeline is a possibly chained sequence of \"commands\". A command is a simple\nvalue (argument) or a function or method call, possibly with multiple arguments:\n\n\tArgument\n\t\tThe result is the value of evaluating the argument.\n\t.Method [Argument...]\n\t\tThe method can be alone or the last element of a chain but,\n\t\tunlike methods in the middle of a chain, it can take arguments.\n\t\tThe result is the value of calling the method with the\n\t\targuments:\n\t\t\tdot.Method(Argument1, etc.)\n\tfunctionName [Argument...]\n\t\tThe result is the value of calling the function associated\n\t\twith the name:\n\t\t\tfunction(Argument1, etc.)\n\t\tFunctions and function names are described below.\n\nPipelines\n\nA pipeline may be \"chained\" by separating a sequence of commands with pipeline\ncharacters '|'. In a chained pipeline, the result of the each command is\npassed as the last argument of the following command. The output of the final\ncommand in the pipeline is the value of the pipeline.\n\nThe output of a command will be either one value or two values, the second of\nwhich has type error. If that second value is present and evaluates to\nnon-nil, execution terminates and the error is returned to the caller of\nExecute.\n\nVariables\n\nA pipeline inside an action may initialize a variable to capture the result.\nThe initialization has syntax\n\n\t$variable := pipeline\n\nwhere $variable is the name of the variable. An action that declares a\nvariable produces no output.\n\nIf a \"range\" action initializes a variable, the variable is set to the\nsuccessive elements of the iteration.  Also, a \"range\" may declare two\nvariables, separated by a comma:\n\n\trange $index, $element := pipeline\n\nin which case $index and $element are set to the successive values of the\narray\/slice index or map key and element, respectively.  Note that if there is\nonly one variable, it is assigned the element; this is opposite to the\nconvention in Go range clauses.\n\nA variable's scope extends to the \"end\" action of the control structure (\"if\",\n\"with\", or \"range\") in which it is declared, or to the end of the template if\nthere is no such control structure.  A template invocation does not inherit\nvariables from the point of its invocation.\n\nWhen execution begins, $ is set to the data argument passed to Execute, that is,\nto the starting value of dot.\n\nExamples\n\nHere are some example one-line templates demonstrating pipelines and variables.\nAll produce the quoted word \"output\":\n\n\t{{\"\\\"output\\\"\"}}\n\t\tA string constant.\n\t{{`\"output\"`}}\n\t\tA raw string constant.\n\t{{printf \"%q\" \"output\"}}\n\t\tA function call.\n\t{{\"output\" | printf \"%q\"}}\n\t\tA function call whose final argument comes from the previous\n\t\tcommand.\n\t{{printf \"%q\" (print \"out\" \"put\")}}\n\t\tA parenthesized argument.\n\t{{\"put\" | printf \"%s%s\" \"out\" | printf \"%q\"}}\n\t\tA more elaborate call.\n\t{{\"output\" | printf \"%s\" | printf \"%q\"}}\n\t\tA longer chain.\n\t{{with \"output\"}}{{printf \"%q\" .}}{{end}}\n\t\tA with action using dot.\n\t{{with $x := \"output\" | printf \"%q\"}}{{$x}}{{end}}\n\t\tA with action that creates and uses a variable.\n\t{{with $x := \"output\"}}{{printf \"%q\" $x}}{{end}}\n\t\tA with action that uses the variable in another action.\n\t{{with $x := \"output\"}}{{$x | printf \"%q\"}}{{end}}\n\t\tThe same, but pipelined.\n\nFunctions\n\nDuring execution functions are found in two function maps: first in the\ntemplate, then in the global function map. By default, no functions are defined\nin the template but the Funcs method can be used to add them.\n\nPredefined global functions are named as follows.\n\n\tand\n\t\tReturns the boolean AND of its arguments by returning the\n\t\tfirst empty argument or the last argument, that is,\n\t\t\"and x y\" behaves as \"if x then y else x\". All the\n\t\targuments are evaluated.\n\tcall\n\t\tReturns the result of calling the first argument, which\n\t\tmust be a function, with the remaining arguments as parameters.\n\t\tThus \"call .X.Y 1 2\" is, in Go notation, dot.X.Y(1, 2) where\n\t\tY is a func-valued field, map entry, or the like.\n\t\tThe first argument must be the result of an evaluation\n\t\tthat yields a value of function type (as distinct from\n\t\ta predefined function such as print). The function must\n\t\treturn either one or two result values, the second of which\n\t\tis of type error. If the arguments don't match the function\n\t\tor the returned error value is non-nil, execution stops.\n\thtml\n\t\tReturns the escaped HTML equivalent of the textual\n\t\trepresentation of its arguments.\n\tindex\n\t\tReturns the result of indexing its first argument by the\n\t\tfollowing arguments. Thus \"index x 1 2 3\" is, in Go syntax,\n\t\tx[1][2][3]. Each indexed item must be a map, slice, or array.\n\tjs\n\t\tReturns the escaped JavaScript equivalent of the textual\n\t\trepresentation of its arguments.\n\tlen\n\t\tReturns the integer length of its argument.\n\tnot\n\t\tReturns the boolean negation of its single argument.\n\tor\n\t\tReturns the boolean OR of its arguments by returning the\n\t\tfirst non-empty argument or the last argument, that is,\n\t\t\"or x y\" behaves as \"if x then x else y\". All the\n\t\targuments are evaluated.\n\tprint\n\t\tAn alias for fmt.Sprint\n\tprintf\n\t\tAn alias for fmt.Sprintf\n\tprintln\n\t\tAn alias for fmt.Sprintln\n\turlquery\n\t\tReturns the escaped value of the textual representation of\n\t\tits arguments in a form suitable for embedding in a URL query.\n\nThe boolean functions take any zero value to be false and a non-zero value to\nbe true.\n\nAssociated templates\n\nEach template is named by a string specified when it is created. Also, each\ntemplate is associated with zero or more other templates that it may invoke by\nname; such associations are transitive and form a name space of templates.\n\nA template may use a template invocation to instantiate another associated\ntemplate; see the explanation of the \"template\" action above. The name must be\nthat of a template associated with the template that contains the invocation.\n\nNested template definitions\n\nWhen parsing a template, another template may be defined and associated with the\ntemplate being parsed. Template definitions must appear at the top level of the\ntemplate, much like global variables in a Go program.\n\nThe syntax of such definitions is to surround each template declaration with a\n\"define\" and \"end\" action.\n\nThe define action names the template being created by providing a string\nconstant. Here is a simple example:\n\n\t`{{define \"T1\"}}ONE{{end}}\n\t{{define \"T2\"}}TWO{{end}}\n\t{{define \"T3\"}}{{template \"T1\"}} {{template \"T2\"}}{{end}}\n\t{{template \"T3\"}}`\n\nThis defines two templates, T1 and T2, and a third T3 that invokes the other two\nwhen it is executed. Finally it invokes T3. If executed this template will\nproduce the text\n\n\tONE TWO\n\nBy construction, a template may reside in only one association. If it's\nnecessary to have a template addressable from multiple associations, the\ntemplate definition must be parsed multiple times to create distinct *Template\nvalues, or must be copied with the Clone or AddParseTree method.\n\nParse may be called multiple times to assemble the various associated templates;\nsee the ParseFiles and ParseGlob functions and methods for simple ways to parse\nrelated templates stored in files.\n\nA template may be executed directly or through ExecuteTemplate, which executes\nan associated template identified by name. To invoke our example above, we\nmight write,\n\n\terr := tmpl.Execute(os.Stdout, \"no data needed\")\n\tif err != nil {\n\t\tlog.Fatalf(\"execution failed: %s\", err)\n\t}\n\nor to invoke a particular template explicitly by name,\n\n\terr := tmpl.ExecuteTemplate(os.Stdout, \"T2\", \"no data needed\")\n\tif err != nil {\n\t\tlog.Fatalf(\"execution failed: %s\", err)\n\t}\n\n*\/\npackage template\n<commit_msg>text\/template: Document that range can be used on chan types.<commit_after>\/\/ Copyright 2011 The Go Authors.

Annotations in the\ntemplate refer to elements of the data structure (typically a field of a struct\nor a key in a map) to control execution and derive values to be displayed.\nExecution of the template walks the structure and sets the cursor, represented\nby a period '.' and called \"dot\", to the value at the current location in the\nstructure as execution proceeds.\n\nThe input text for a template is UTF-8-encoded text in any format.\n\"Actions\"--data evaluations or control structures--are delimited by\n\"{{\" and \"}}\"; all text outside actions is copied to the output unchanged.\nActions may not span newlines, although comments can.\n\nOnce constructed, a template may be executed safely in parallel.\n\nHere is a trivial example that prints \"17 items are made of wool\".\n\n\ttype Inventory struct {\n\t\tMaterial string\n\t\tCount    uint\n\t}\n\tsweaters := Inventory{\"wool\", 17}\n\ttmpl, err := template.New(\"test\").Parse(\"{{.Count}} items are made of {{.Material}}\")\n\tif err != nil { panic(err) }\n\terr = tmpl.Execute(os.Stdout, sweaters)\n\tif err != nil { panic(err) }\n\nMore intricate examples appear below.\n\nActions\n\nHere is the list of actions. \"Arguments\" and \"pipelines\" are evaluations of\ndata, defined in detail below.\n\n*\/\n\/\/\t{{\/* a comment *\/}}\n\/\/\t\tA comment; discarded.

These behave like Go's untyped\n\t  constants, although raw strings may not span newlines.\n\t- The keyword nil, representing an untyped Go nil.\n\t- The character '.' (period):\n\t\t.\n\t  The result is the value of dot.\n\t- A variable name, which is a (possibly empty) alphanumeric string\n\t  preceded by a dollar sign, such as\n\t\t$piOver2\n\t  or\n\t\t$\n\t  The result is the value of the variable.\n\t  Variables are described below.\n\t- The name of a field of the data, which must be a struct, preceded\n\t  by a period, such as\n\t\t.Field\n\t  The result is the value of the field. Field invocations may be\n\t  chained:\n\t    .Field1.Field2\n\t  Fields can also be evaluated on variables, including chaining:\n\t    $x.Field1.Field2\n\t- The name of a key of the data, which must be a map, preceded\n\t  by a period, such as\n\t\t.Key\n\t  The result is the map element value indexed by the key.\n\t  Key invocations may be chained and combined with fields to any\n\t  depth:\n\t    .Field1.Key1.Field2.Key2\n\t  Although the key must be an alphanumeric identifier, unlike with\n\t  field names they do not need to start with an upper case letter.\n\t  Keys can also be evaluated on variables, including chaining:\n\t    $x.key1.key2\n\t- The name of a niladic method of the data, preceded by a period,\n\t  such as\n\t\t.Method\n\t  The result is the value of invoking the method with dot as the\n\t  receiver, dot.Method(). Such a method must have one return value (of\n\t  any type) or two return values, the second of which is an error.\n\t  If it has two and the returned error is non-nil, execution terminates\n\t  and an error is returned to the caller as the value of Execute.\n\t  Method invocations may be chained and combined with fields and keys\n\t  to any depth:\n\t    .Field1.Key1.Method1.Field2.Key2.Method2\n\t  Methods can also be evaluated on variables, including chaining:\n\t    $x.Method1.Field\n\t- The name of a niladic function, such as\n\t\tfun\n\t  The result is the value of invoking the function, fun(). The return\n\t  types and values behave as in methods. Functions and function\n\t  names are described below.\n\t- A parenthesized instance of one the above, for grouping. The result\n\t  may be accessed by a field or map key invocation.\n\t\tprint (.F1 arg1) (.F2 arg2)\n\t\t(.StructValuedMethod \"arg\").Field\n\nArguments may evaluate to any type; if they are pointers the implementation\nautomatically indirects to the base type when required.\nIf an evaluation yields a function value, such as a function-valued\nfield of a struct, the function is not invoked automatically, but it\ncan be used as a truth value for an if action and the like. To invoke\nit, use the call function, defined below.\n\nA pipeline is a possibly chained sequence of \"commands\". A command is a simple\nvalue (argument) or a function or method call, possibly with multiple arguments:\n\n\tArgument\n\t\tThe result is the value of evaluating the argument.\n\t.Method [Argument...]\n\t\tThe method can be alone or the last element of a chain but,\n\t\tunlike methods in the middle of a chain, it can take arguments.\n\t\tThe result is the value of calling the method with the\n\t\targuments:\n\t\t\tdot.Method(Argument1, etc.)\n\tfunctionName [Argument...]\n\t\tThe result is the value of calling the function associated\n\t\twith the name:\n\t\t\tfunction(Argument1, etc.)\n\t\tFunctions and function names are described below.\n\nPipelines\n\nA pipeline may be \"chained\" by separating a sequence of commands with pipeline\ncharacters '|'. In a chained pipeline, the result of the each command is\npassed as the last argument of the following command. The output of the final\ncommand in the pipeline is the value of the pipeline.\n\nThe output of a command will be either one value or two values, the second of\nwhich has type error. If that second value is present and evaluates to\nnon-nil, execution terminates and the error is returned to the caller of\nExecute.\n\nVariables\n\nA pipeline inside an action may initialize a variable to capture the result.\nThe initialization has syntax\n\n\t$variable := pipeline\n\nwhere $variable is the name of the variable. An action that declares a\nvariable produces no output.\n\nIf a \"range\" action initializes a variable, the variable is set to the\nsuccessive elements of the iteration.  Also, a \"range\" may declare two\nvariables, separated by a comma:\n\n\trange $index, $element := pipeline\n\nin which case $index and $element are set to the successive values of the\narray\/slice index or map key and element, respectively.  Note that if there is\nonly one variable, it is assigned the element; this is opposite to the\nconvention in Go range clauses.\n\nA variable's scope extends to the \"end\" action of the control structure (\"if\",\n\"with\", or \"range\") in which it is declared, or to the end of the template if\nthere is no such control structure.  A template invocation does not inherit\nvariables from the point of its invocation.\n\nWhen execution begins, $ is set to the data argument passed to Execute, that is,\nto the starting value of dot.\n\nExamples\n\nHere are some example one-line templates demonstrating pipelines and variables.\nAll produce the quoted word \"output\":\n\n\t{{\"\\\"output\\\"\"}}\n\t\tA string constant.\n\t{{`\"output\"`}}\n\t\tA raw string constant.\n\t{{printf \"%q\" \"output\"}}\n\t\tA function call.\n\t{{\"output\" | printf \"%q\"}}\n\t\tA function call whose final argument comes from the previous\n\t\tcommand.\n\t{{printf \"%q\" (print \"out\" \"put\")}}\n\t\tA parenthesized argument.\n\t{{\"put\" | printf \"%s%s\" \"out\" | printf \"%q\"}}\n\t\tA more elaborate call.\n\t{{\"output\" | printf \"%s\" | printf \"%q\"}}\n\t\tA longer chain.\n\t{{with \"output\"}}{{printf \"%q\" .}}{{end}}\n\t\tA with action using dot.\n\t{{with $x := \"output\" | printf \"%q\"}}{{$x}}{{end}}\n\t\tA with action that creates and uses a variable.\n\t{{with $x := \"output\"}}{{printf \"%q\" $x}}{{end}}\n\t\tA with action that uses the variable in another action.\n\t{{with $x := \"output\"}}{{$x | printf \"%q\"}}{{end}}\n\t\tThe same, but pipelined.\n\nFunctions\n\nDuring execution functions are found in two function maps: first in the\ntemplate, then in the global function map. By default, no functions are defined\nin the template but the Funcs method can be used to add them.\n\nPredefined global functions are named as follows.\n\n\tand\n\t\tReturns the boolean AND of its arguments by returning the\n\t\tfirst empty argument or the last argument, that is,\n\t\t\"and x y\" behaves as \"if x then y else x\". All the\n\t\targuments are evaluated.\n\tcall\n\t\tReturns the result of calling the first argument, which\n\t\tmust be a function, with the remaining arguments as parameters.\n\t\tThus \"call .X.Y 1 2\" is, in Go notation, dot.X.Y(1, 2) where\n\t\tY is a func-valued field, map entry, or the like.\n\t\tThe first argument must be the result of an evaluation\n\t\tthat yields a value of function type (as distinct from\n\t\ta predefined function such as print). The function must\n\t\treturn either one or two result values, the second of which\n\t\tis of type error. If the arguments don't match the function\n\t\tor the returned error value is non-nil, execution stops.\n\thtml\n\t\tReturns the escaped HTML equivalent of the textual\n\t\trepresentation of its arguments.\n\tindex\n\t\tReturns the result of indexing its first argument by the\n\t\tfollowing arguments. Thus \"index x 1 2 3\" is, in Go syntax,\n\t\tx[1][2][3]. Each indexed item must be a map, slice, or array.\n\tjs\n\t\tReturns the escaped JavaScript equivalent of the textual\n\t\trepresentation of its arguments.\n\tlen\n\t\tReturns the integer length of its argument.\n\tnot\n\t\tReturns the boolean negation of its single argument.\n\tor\n\t\tReturns the boolean OR of its arguments by returning the\n\t\tfirst non-empty argument or the last argument, that is,\n\t\t\"or x y\" behaves as \"if x then x else y\". All the\n\t\targuments are evaluated.\n\tprint\n\t\tAn alias for fmt.Sprint\n\tprintf\n\t\tAn alias for fmt.Sprintf\n\tprintln\n\t\tAn alias for fmt.Sprintln\n\turlquery\n\t\tReturns the escaped value of the textual representation of\n\t\tits arguments in a form suitable for embedding in a URL query.\n\nThe boolean functions take any zero value to be false and a non-zero value to\nbe true.\n\nAssociated templates\n\nEach template is named by a string specified when it is created. Also, each\ntemplate is associated with zero or more other templates that it may invoke by\nname; such associations are transitive and form a name space of templates.\n\nA template may use a template invocation to instantiate another associated\ntemplate; see the explanation of the \"template\" action above. The name must be\nthat of a template associated with the template that contains the invocation.\n\nNested template definitions\n\nWhen parsing a template, another template may be defined and associated with the\ntemplate being parsed. Template definitions must appear at the top level of the\ntemplate, much like global variables in a Go program.\n\nThe syntax of such definitions is to surround each template declaration with a\n\"define\" and \"end\" action.\n\nThe define action names the template being created by providing a string\nconstant. Here is a simple example:\n\n\t`{{define \"T1\"}}ONE{{end}}\n\t{{define \"T2\"}}TWO{{end}}\n\t{{define \"T3\"}}{{template \"T1\"}} {{template \"T2\"}}{{end}}\n\t{{template \"T3\"}}`\n\nThis defines two templates, T1 and T2, and a third T3 that invokes the other two\nwhen it is executed. Finally it invokes T3. If executed this template will\nproduce the text\n\n\tONE TWO\n\nBy construction, a template may reside in only one association. If it's\nnecessary to have a template addressable from multiple associations, the\ntemplate definition must be parsed multiple times to create distinct *Template\nvalues, or must be copied with the Clone or AddParseTree method.\n\nParse may be called multiple times to assemble the various associated templates;\nsee the ParseFiles and ParseGlob functions and methods for simple ways to parse\nrelated templates stored in files.\n\nA template may be executed directly or through ExecuteTemplate, which executes\nan associated template identified by name.

arbitrary user or account id (client id) - Integrated basic redis support with radix client for basic things such as tracking # hits to a given country and continent on each hour of the day - Updated flags to include the -i for IP and -p for PORT - Added -db flag to allow selection of desired redis DB index - Added code to replace special tild seperator ~ with - in any of the values that are to be

As the API surface grows to add more KIND objects\n\/\/ that could exist in a Namespace, the number of calls that the namespace\n\/\/ controller must orchestrate grows since it must LIST, DELETE (1x1) each\n\/\/ KIND.\n\/\/ There is work underway to improve this, but it's\n\/\/ most likely not going to get significantly better until etcd v3.\n\/\/ Going back to this test, this test generates 100 Namespace objects, and then\n\/\/ rapidly deletes all of them.  This causes the NamespaceController to observe\n\/\/ and attempt to process a large number of deletes concurrently.  In effect,\n\/\/ it's like running 100 traditional e2e tests in parallel.  If the namespace\n\/\/ controller orchestrating deletes is slowed down deleting another test's\n\/\/ content then this test may fail.  Since the goal of this test is to soak\n\/\/ Namespace creation, and soak Namespace deletion, its not appropriate to\n\/\/ further soak the cluster with other parallel Namespace deletion activities\n\/\/ that each have a variable amount of content in the associated Namespace.\n\/\/ When run in [Serial] this test appears to delete Namespace objects at a\n\/\/ rate of approximately 1

Refactoring arbitrary\nstatements (or sequences of statements) is a less well-defined problem\nand is less amenable to this approach.\n\nA pattern that contains a function literal (and hence statements)\nnever matches.\n\nThere is no way to generalize over related types, e.g. to express that\na wildcard may have any integer type, for example.\n\nIt is not possible to replace an expression by one of a different\ntype, even in contexts where this is legal, such as x in fmt.Print(x).\n\nThe struct literals T{x} and T{K: x} cannot both be matched by a single\ntemplate.\n\n\nSAFETY\n\nVerifying that a transformation does not introduce type errors is very\ncomplex in the general case.  An innocuous-looking replacement of one\nconstant by another (e.g. 1 to 2) may cause type errors relating to\narray types and indices, for example.  The tool performs only very\nsuperficial checks of type preservation.\n\n\nIMPORTS\n\nAlthough the matching algorithm is fully aware of scoping rules, the\nreplacement algorithm is not, so the replacement code may contain\nincorrect identifier syntax for imported objects if there are dot\nimports, named imports or locally shadowed package names in the input\nprogram.\n\nImports are added as needed, but they are not removed as needed.\nRun 'goimports' on the modified file for now.\n\nDot imports are forbidden in the template.\n\n\nTIPS\n====\n\nSometimes a little creativity is required to implement the desired\nmigration.  This section lists a few tips and tricks.\n\nTo remove the final parameter from a function, temporarily change the\nfunction signature so that the final parameter is variadic, as this\nallows legal calls both with and without the argument.  Then use eg to\nremove the final argument from all callers, and remove the variadic\nparameter by hand.  The reverse process can be used to add a final\nparameter.\n\nTo add or remove parameters other than the final one, you must do it in\nstages: (1) declare a variant function f' with a different name and the\ndesired parameters; (2) use eg to transform calls to f into calls to f',\nchanging the arguments as needed; (3) change the declaration of f to\nmatch f'; (4) use eg to rename f' to f in all calls; (5) delete f'.\n`\n\n\/\/ TODO(adonovan): expand upon the above documentation as an HTML page.\n\n\/\/ A Transformer represents a single example-based transformation.\ntype Transformer struct {\n\tfset           *token.FileSet\n\tverbose        bool\n\tinfo           *types.Info \/\/ combined type info for template\/input\/output ASTs\n\tseenInfos      map[*types.Info]bool\n\twildcards      map[*types.Var]bool                \/\/ set of parameters in func before()\n\tenv            map[string]ast.Expr                \/\/ maps parameter name to wildcard binding\n\timportedObjs   map[types.Object]*ast.SelectorExpr \/\/ objects imported by after().\n\tbefore, after  ast.Expr\n\tallowWildcards bool\n\n\t\/\/ Working state of Transform():\n\tnsubsts    int            \/\/ number of substitutions made\n\tcurrentPkg *types.Package \/\/ package of current call\n}\n\n\/\/ NewTransformer returns a transformer based on the specified template,\n\/\/ a single-file package containing \"before\" and \"after\" functions as\n\/\/ described in the package documentation.\n\/\/ tmplInfo is the type information for tmplFile.\n\/\/\nfunc NewTransformer(fset *token.FileSet, tmplPkg *types.Package, tmplFile *ast.File, tmplInfo *types.Info, verbose bool) (*Transformer, error) {\n\t\/\/ Check the template.\n\tbeforeSig := funcSig(tmplPkg, \"before\")\n\tif beforeSig == nil {\n\t\treturn nil, fmt.Errorf(\"no 'before' func found in template\")\n\t}\n\tafterSig := funcSig(tmplPkg, \"after\")\n\tif afterSig == nil {\n\t\treturn nil, fmt.Errorf(\"no 'after' func found in template\")\n\t}\n\n\t\/\/ TODO(adonovan): should we also check the names of the params match?\n\tif !types.Identical(afterSig, beforeSig) {\n\t\treturn nil, fmt.Errorf(\"before %s and after %s functions have different signatures\",\n\t\t\tbeforeSig, afterSig)\n\t}\n\n\tfor _, imp := range tmplFile.Imports {\n\t\tif imp.Name != nil && imp.Name.Name == \".\" {\n\t\t\t\/\/ Dot imports are currently forbidden.

This section lists a few tips and tricks.\n\nTo remove the final parameter from a function, temporarily change the\nfunction signature so that the final parameter is variadic, as this\nallows legal calls both with and without the argument.  Then use eg to\nremove the final argument from all callers, and remove the variadic\nparameter by hand.  The reverse process can be used to add a final\nparameter.\n\nTo add or remove parameters other than the final one, you must do it in\nstages: (1) declare a variant function f' with a different name and the\ndesired parameters; (2) use eg to transform calls to f into calls to f',\nchanging the arguments as needed; (3) change the declaration of f to\nmatch f'; (4) use eg to rename f' to f in all calls; (5) delete f'.\n`\n\n\/\/ TODO(adonovan): expand upon the above documentation as an HTML page.\n\n\/\/ A Transformer represents a single example-based transformation.\ntype Transformer struct {\n\tfset           *token.FileSet\n\tverbose        bool\n\tinfo           *types.Info \/\/ combined type info for template\/input\/output ASTs\n\tseenInfos      map[*types.Info]bool\n\twildcards      map[*types.Var]bool                \/\/ set of parameters in func before()\n\tenv            map[string]ast.Expr                \/\/ maps parameter name to wildcard binding\n\timportedObjs   map[types.Object]*ast.SelectorExpr \/\/ objects imported by after().\n\tbefore, after  ast.Expr\n\tallowWildcards bool\n\n\t\/\/ Working state of Transform():\n\tnsubsts    int            \/\/ number of substitutions made\n\tcurrentPkg *types.Package \/\/ package of current call\n}\n\n\/\/ NewTransformer returns a transformer based on the specified template,\n\/\/ a single-file package containing \"before\" and \"after\" functions as\n\/\/ described in the package documentation.\n\/\/ tmplInfo is the type information for tmplFile.\n\/\/\nfunc NewTransformer(fset *token.FileSet, tmplPkg *types.Package, tmplFile *ast.File, tmplInfo *types.Info, verbose bool) (*Transformer, error) {\n\t\/\/ Check the template.\n\tbeforeSig := funcSig(tmplPkg, \"before\")\n\tif beforeSig == nil {\n\t\treturn nil, fmt.Errorf(\"no 'before' func found in template\")\n\t}\n\tafterSig := funcSig(tmplPkg, \"after\")\n\tif afterSig == nil {\n\t\treturn nil, fmt.Errorf(\"no 'after' func found in template\")\n\t}\n\n\t\/\/ TODO(adonovan): should we also check the names of the params match?\n\tif !types.Identical(afterSig, beforeSig) {\n\t\treturn nil, fmt.Errorf(\"before %s and after %s functions have different signatures\",\n\t\t\tbeforeSig, afterSig)\n\t}\n\n\tfor _, imp := range tmplFile.Imports {\n\t\tif imp.Name != nil && imp.Name.Name == \".\" {\n\t\t\t\/\/ Dot imports are currently forbidden.

But with a typical hash table, if you add or remove a server,\n\/\/ almost all keys will get remapped to different results, which basically could bring your service\n\/\/ to a grinding halt while the caches get rebuilt.\n\/\/\n\/\/ With a consistent hash, adding or removing a server drastically reduces the number of keys that\n\/\/ get remapped.\n\/\/\n\/\/ Read more about consistent hashing on wikipedia:  http:\/\/en.wikipedia.org\/wiki\/Consistent_hashing\n\/\/\npackage consistent\n\nimport (\n\t\"errors\"\n\t\"hash\/crc32\"\n\t\"sort\"\n\t\"strconv\"\n)\n\ntype uints []uint32\n\n\/\/ Len returns the length of the uints array.\nfunc (x uints) Len() int { return len(x) }\n\n\/\/ Less returns true if element i is less than element j.\nfunc (x uints) Less(i, j int) bool { return x[i] < x[j] }\n\n\/\/ Swap exchanges elements i and j.\nfunc (x uints) Swap(i, j int) { x[i], x[j] = x[j], x[i] }\n\n\/\/ ErrEmptyCircle is the error returned when trying to get an element when nothing has been added to hash.\nvar ErrEmptyCircle = errors.New(\"empty circle\")\n\n\/\/ Consistent holds the information about the members of the consistent hash circle.\ntype Consistent struct {\n\tcircle           map[uint32]string\n\tsortedHashes     uints\n\tNumberOfReplicas int\n\tcount            int64\n\tscratch          [64]byte\n}\n\n\/\/ New creates a new Consistent object with a default setting of 20 replicas for each entry.\n\/\/\n\/\/ To change the number of replicas, set NumberOfReplicas before adding entries.\nfunc New() *Consistent {\n\tc := new(Consistent)\n\tc.NumberOfReplicas = 20\n\tc.circle = make(map[uint32]string)\n\treturn c\n}\n\n\/\/ eltKey generates a string key for an element with an index.\nfunc (c *Consistent) eltKey(elt string, idx int) string {\n\treturn elt + \"|\" + strconv.Itoa(idx)\n}\n\n\/\/ Add inserts a string element in the consistent hash.\nfunc (c *Consistent) Add(elt string) {\n\tfor i := 0; i < c.NumberOfReplicas; i++ {\n\t\tc.circle[c.hashKey(c.eltKey(elt, i))] = elt\n\t}\n\tc.updateSortedHashes()\n\tc.count++\n}\n\n\/\/ Remove removes an element from the hash.\nfunc (c *Consistent) Remove(elt string) {\n\tfor i := 0; i < c.NumberOfReplicas; i++ {\n\t\tdelete(c.circle, c.hashKey(c.eltKey(elt, i)))\n\t}\n\tc.updateSortedHashes()\n\tc.count--\n}\n\n\/\/ Get returns an element close to where name hashes to in the circle.\nfunc (c *Consistent) Get(name string) (string, error) {\n\tif len(c.circle) == 0 {\n\t\treturn \"\", ErrEmptyCircle\n\t}\n\tkey := c.hashKey(name)\n\ti := c.search(key)\n\treturn c.circle[c.sortedHashes[i]], nil\n}\n\nfunc (c *Consistent) search(key uint32) (i int) {\n\tf := func(x int) bool {\n\t\treturn c.sortedHashes[x] > key\n\t}\n\ti = sort.Search(len(c.sortedHashes), f)\n\tif i >= len(c.sortedHashes) {\n\t\ti = 0\n\t}\n\treturn\n}\n\n\/\/ GetTwo returns the two closest distinct elements to the name input in the circle.\nfunc (c *Consistent) GetTwo(name string) (string, string, error) {\n\tif len(c.circle) == 0 {\n\t\treturn \"\", \"\", ErrEmptyCircle\n\t}\n\tkey := c.hashKey(name)\n\ti := c.search(key)\n\ta := c.circle[c.sortedHashes[i]]\n\n\tif c.count == 1 {\n\t\treturn a, \"\", nil\n\t}\n\n\tstart := i\n\tvar b string\n\tfor i = start + 1; i != start; i++ {\n\t\tif i >= len(c.sortedHashes) {\n\t\t\ti = 0\n\t\t}\n\t\tb = c.circle[c.sortedHashes[i]]\n\t\tif b != a {\n\t\t\tbreak\n\t\t}\n\t}\n\treturn a, b, nil\n}\n\nfunc (c *Consistent) hashKey(key string) uint32 {\n\tif len(key) < 64 {\n\t\tcopy(c.scratch[:], key)\n\t\treturn crc32.ChecksumIEEE(c.scratch[:len(key)])\n\t}\n\treturn crc32.ChecksumIEEE([]byte(key))\n}\n\nfunc (c *Consistent) updateSortedHashes() {\n\thashes := c.sortedHashes[:0]\n\t\/\/reallocate if we're holding on to too much (1\/4th)\n\tif cap(c.sortedHashes)\/(c.NumberOfReplicas*4) > len(c.circle) {\n\t\thashes = nil\n\t}\n\tfor k := range c.circle {\n\t\thashes = append(hashes, k)\n\t}\n\tsort.Sort(hashes)\n\tc.sortedHashes = hashes\n}\n<|endoftext|>"}

documentation.<commit_after>\/*\n\nPackage tsi1 provides a memory-mapped index implementation that supports\nhigh cardinality series.\n\nOverview\n\nThe top-level object in tsi1 is the Index. It is the primary access point from\nthe rest of the system. The Index is composed of LogFile and IndexFile objects.\n\nLog files are small write-ahead log files that record new series immediately\nin the order that they are received. The data within the file is indexed\nin-memory so it can be quickly accessed. When the system is restarted, this log\nfile is replayed and the in-memory representation is rebuilt.\n\nIndex files also contain series information, however, they are highly indexed\nso that reads can be performed quickly. Index files are built through a process\ncalled compaction where a log file or multiple index files are merged together.\n\n\nOperations\n\nThe index can perform many tasks related to series, measurement, & tag data.\nAll data is inserted by adding a series to the index. When adding a series,\nthe measurement, tag keys, and tag values are all extracted and indexed\nseparately.\n\nOnce a series has been added, it can be removed in several ways. First, the\nindividual series can be removed. Second, it can be removed as part of a bulk\noperation by deleting the entire measurement.\n\nThe query engine needs to be able to look up series in a variety of ways such\nas by measurement name, by tag value, or by using regular expressions. The\nindex provides an API to iterate over subsets of series and perform set\noperations such as unions and intersections.\n\n\nLog File Layout\n\nThe write-ahead file that series initially are inserted into simply appends\nall new operations sequentially. It is simply composed of a series of log\nentries. An entry contains a flag to specify the operation type, the measurement\nname, the tag set, and a checksum.\n\n\t┏━━━━━━━━━LogEntry━━━━━━━━━┓\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │         Flag         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │     Measurement      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Key\/Value       │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Key\/Value       │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Key\/Value       │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │       Checksum       │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┗━━━━━━━━━━━━━━━━━━━━━━━━━━┛\n\nWhen the log file is replayed, if the checksum is incorrect or the entry is\nincomplete (because of a partially failed write) then the log is truncated.\n\n\nIndex File Layout\n\nThe index file is composed of 3 main block types: one series block, one or more\ntag blocks, and one measurement block. At the end of the index file is a\ntrailer that records metadata such as the offsets to these blocks.\n\n\nSeries Block Layout\n\nThe series block stores raw series keys in sorted order. It also provides hash\nindexes so that series can be looked up quickly. Hash indexes are inserted\nperiodically so that memory size is limited at write time. Once all the series\nand hash indexes have been written then a list of index entries are written\nso that hash indexes can be looked up via binary search.\n\nThe end of the block contains two HyperLogLog++ sketches which track the\nestimated number of created series and deleted series. After the sketches is\na trailer which contains metadata about the block.\n\n\t┏━━━━━━━SeriesBlock━━━━━━━━┓\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │      Series Key      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │    Index Entries     │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │     HLL Sketches     │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │       Trailer        │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┗━━━━━━━━━━━━━━━━━━━━━━━━━━┛\n\n\nTag Block Layout\n\nAfter the series block is one or more tag blocks. One of these blocks exists\nfor every measurement in the index file. The block is structured as a sorted\nlist of values for each key and then a sorted list of keys. Each of these lists\nhas their own hash index for fast direct lookups.\n\n\t┏━━━━━━━━Tag Block━━━━━━━━━┓\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │        Value         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │        Value         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │        Value         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │        Value         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │        Value         │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │         Key          │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │         Key          │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │       Trailer        │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┗━━━━━━━━━━━━━━━━━━━━━━━━━━┛\n\nEach entry for values contains a sorted list of offsets for series keys that use\nthat value.

This allows all series for\na measurement to be traversed quickly and it allows fast direct lookups of\nmeasurements and their tags.\n\nThis block also contains HyperLogLog++ sketches for new and deleted\nmeasurements.\n\n\t┏━━━━Measurement Block━━━━━┓\n\t┃ ┌──────────────────────┐ ┃\n\t┃ │     Measurement      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │     Measurement      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │     Measurement      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │                      │ ┃\n\t┃ │      Hash Index      │ ┃\n\t┃ │                      │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │     HLL Sketches     │ ┃\n\t┃ ├──────────────────────┤ ┃\n\t┃ │       Trailer        │ ┃\n\t┃ └──────────────────────┘ ┃\n\t┗━━━━━━━━━━━━━━━━━━━━━━━━━━┛\n\n\nManifest file\n\nThe index is simply an ordered set of log and index files. These files can be\nmerged together or rewritten but their order must always be the same. This is\nbecause series, measurements, & tags can be marked as deleted (aka tombstoned)\nand this action needs to be tracked in time order.\n\nWhenever the set of active files is changed, a manifest file is written to\ntrack the set. The manifest specifies the ordering of files and, on startup,\nall files not in the manifest are removed from the index directory.\n\n\nCompacting index files\n\nCompaction is the process of taking files and merging them together into a\nsingle file. There are two stages of compaction within TSI.\n\nFirst, once log files exceed a size threshold then they are compacted into an\nindex file. This threshold is relatively small because log files must maintain\ntheir index in the heap which TSI tries to avoid. Small log files are also very\nquick to convert into an index file so this is done aggressively.\n\nSecond, once a contiguous set of index files exceed a factor (e.g. 10x) then\nthey are all merged together into a single index file and the old files are\ndiscarded. Because all blocks are written in sorted order, the new index file\ncan be streamed and minimize memory use.\n\n\nConcurrency\n\nIndex files are immutable so they do not require fine grained locks, however,\ncompactions require that we track which files are in use so they are not\ndiscarded too soon. This is done by using reference counting with file sets.\n\nA file set is simply an ordered list of index files. When the current file set\nis obtained from the index, a counter is incremented to track its usage. Once\nthe user is done with the file set, it is released and the counter is\ndecremented. A file cannot be removed from the file system until this counter\nreturns to zero.\n\nBesides the reference counting, there are no other locking mechanisms when\nreading or writing index files. Log files, however, do require a lock whenever\nthey are accessed. This is another reason to minimize log file size.\n\n\n*\/\npackage tsi1\n<|endoftext|>"}
