{"text":"<commit_before>\/\/ Copyright 2017, Kerby Shedden and the Muscato contributors.\n\n\/\/ muscato_screen is an initial screening step used by Muscato to\n\/\/ identify candidate matches of a set of reads into a set of target\n\/\/ gene sequences.  The results of the screen may contain false\n\/\/ positives, but will not contain any false negatives.\n\/\/\n\/\/ The approach is to use a Bloom filter to sketch the reads based on\n\/\/ the subsequences that appear at defined offsets within the reads.\n\/\/ For example, if position 10 is an offset and we are looking at\n\/\/ subequences of width 15, then the read subsequences from position\n\/\/ 10 through position 25 are entered into a Bloom filter.  Then, we\n\/\/ scan through every target gene looking for matches to the Bloom\n\/\/ filter.  When a match occurs, the match position (in the target)\n\/\/ and flanking sequences are saved for subequent checking against the\n\/\/ full read sequence.\n\/\/\n\/\/ A simple entropy check is used to avoid considering subsequences\n\/\/ that could match large numbers of reads or genes (and hence would\n\/\/ be uninformative).  Currently, this check is based on the number of\n\/\/ distinct dinucleotide subsequences in the window (e.g. in the\n\/\/ 15-mer in the example above).\n\/\/\n\/\/ The results are saved in files named bmatch*.txt.sz, where * is the\n\/\/ window number.\n\/\/\n\/\/ The format of the bmatch files is:\n\/\/\n\/\/ (window sequence) (left tail) (right tail) (gene id) (position)\n\npackage main\n\nimport (\n\t\"bufio\"\n\t\"bytes\"\n\t\"fmt\"\n\t\"io\"\n\t\"log\"\n\t\"math\/rand\"\n\t\"os\"\n\t\"path\"\n\t\"strings\"\n\t\"sync\"\n\n\t\"github.com\/chmduquesne\/rollinghash\"\n\t\"github.com\/chmduquesne\/rollinghash\/buzhash32\"\n\t\"github.com\/golang-collections\/go-datastructures\/bitarray\"\n\t\"github.com\/golang\/snappy\"\n\t\"github.com\/kshedden\/seqmatch\/utils\"\n)\n\nconst (\n\t\/\/ Number of goroutines, should probably scale with the number\n\t\/\/ of aailable cores.\n\tconcurrency int = 100\n)\n\nvar (\n\t\/\/ A log\n\tlogger *log.Logger\n\n\t\/\/ Configuration information\n\tconfig *utils.Config\n\n\t\/\/ All working files are stored here\n\ttmpdir string\n\n\t\/\/ Bitarrays that back the Bloom filters\n\tsmp []bitarray.BitArray\n\n\t\/\/ Tables to produce independent running hashes\n\ttables [][256]uint32\n\n\t\/\/ Communicate results back to driver\n\thitchan chan rec\n\n\t\/\/ Semaphore for limiting goroutines\n\tlimit chan bool\n\n\t\/\/ Line length for output\n\tbufsize int\n)\n\n\/\/ genTables generates base hash functions for a collection of rolling hashes.\nfunc genTables() {\n\ttables = make([][256]uint32, config.NumHash)\n\tfor j := 0;

The results of the screen may contain false\n\/\/ positives, but will not contain any false negatives.\n\/\/\n\/\/ The approach is to use a Bloom filter to sketch the reads based on\n\/\/ the subsequences that appear at defined offsets within the reads.\n\/\/ For example, if position 10 is an offset and we are looking at\n\/\/ subequences of width 15, then the read subsequences from position\n\/\/ 10 through position 25 are entered into a Bloom filter.  Then, we\n\/\/ scan through every target gene looking for matches to the Bloom\n\/\/ filter.  When a match occurs, the match position (in the target)\n\/\/ and flanking sequences are saved for subequent checking against the\n\/\/ full read sequence.\n\/\/\n\/\/ A simple entropy check is used to avoid considering subsequences\n\/\/ that could match large numbers of reads or genes (and hence would\n\/\/ be uninformative).  Currently, this check is based on the number of\n\/\/ distinct dinucleotide subsequences in the window (e.g. in the\n\/\/ 15-mer in the example above).\n\/\/\n\/\/ The results are saved in files named bmatch*.txt.sz, where * is the\n\/\/ window number.\n\/\/\n\/\/ The format of the bmatch files is:\n\/\/\n\/\/ (window sequence) (left tail) (right tail) (gene id) (position)\n\npackage main\n\nimport (\n\t\"bufio\"\n\t\"bytes\"\n\t\"fmt\"\n\t\"io\"\n\t\"log\"\n\t\"math\/rand\"\n\t\"os\"\n\t\"path\"\n\t\"strings\"\n\t\"sync\"\n\n\t\"github.com\/chmduquesne\/rollinghash\"\n\t\"github.com\/chmduquesne\/rollinghash\/buzhash32\"\n\t\"github.com\/golang-collections\/go-datastructures\/bitarray\"\n\t\"github.com\/golang\/snappy\"\n\t\"github.com\/kshedden\/seqmatch\/utils\"\n)\n\nconst (\n\t\/\/ Number of goroutines, should probably scale with the number\n\t\/\/ of aailable cores.\n\tconcurrency int = 100\n)\n\nvar (\n\t\/\/ A log\n\tlogger *log.Logger\n\n\t\/\/ Configuration information\n\tconfig *utils.Config\n\n\t\/\/ All working files are stored here\n\ttmpdir string\n\n\t\/\/ Bitarrays that back the Bloom filters\n\tsmp []bitarray.BitArray\n\n\t\/\/ Tables to produce independent running hashes\n\ttables [][256]uint32\n\n\t\/\/ Communicate results back to driver\n\thitchan chan rec\n\n\t\/\/ Semaphore for limiting goroutines\n\tlimit chan bool\n\n\t\/\/ Line length for output\n\tbufsize int\n)\n\n\/\/ genTables generates base hash functions for a collection of rolling hashes.\nfunc genTables() {\n\ttables = make([][256]uint32, config.NumHash)\n\tfor j := 0;

filename is path to the\n\/\/ file to log to.  It can be a relative path (with respect to the\n\/\/ current working directory) or an absolute path.  maxFileSize is the\n\/\/ approximate file size that will be allowed before the log file is\n\/\/ rotated.  Rotated log files will have suffix of the form\n\/\/ .YYYY-MM-DDTHH-MM-SS or .YYYY-MM-DDTHH-MM-SS-N (where N is an\n\/\/ incrementing serial number used to resolve conflicts) appended to\n\/\/ them.  Set maxFileSize to a non-positive number if you wish there\n\/\/ to be no limit.  maxRotatedLogs specifies the maximum number of\n\/\/ rotated logs allowed before old logs are deleted.  If\n\/\/ rotateIfExists is set to true and a log file with the same filename\n\/\/ already exists, then the current one will be rotated.  If\n\/\/ rotateIfExists is set to true and a log file with the same filename\n\/\/ already exists, then the current log file will be appended to.  If\n\/\/ a log file with the same filename does not exist, then a new log\n\/\/ file is created regardless of the value of rotateIfExists.  As\n\/\/ RotatingFileAppender is asynchronous, an errHandler can be provided\n\/\/ that will be called when an error occurs.  It can set to nil if you\n\/\/ do not want to provide one.  The return value headerGenerator, if\n\/\/ not nil, is logged at the beginning of every log file.\n\/\/\n\/\/ Note that after creating a RollingFileAppender with New(), you will\n\/\/ probably want to defer a call to RollingFileAppender's Close() (or\n\/\/ at least Flush()).  This ensures that in case of program exit\n\/\/ (normal or panicking) that any pending logs are logged.\nfunc New(filename string, maxFileSize int64, maxRotatedLogs int, rotateIfExists bool, headerGenerator func() []string) (*RollingFileAppender, error) {\n\tif headerGenerator == nil {\n\t\theaderGenerator = func() []string {\n\t\t\treturn []string{}\n\t\t}\n\t}\n\n\tabsPath, err := filepath.Abs(filename)\n\tif err != nil {\n\t\treturn nil, err\n\t}\n\n\tappender := &RollingFileAppender{\n\t\tMaxFileSize:     maxFileSize,\n\t\tMaxRotatedLogs:  maxRotatedLogs,\n\t\tabsPath:         absPath,\n\t\theaderGenerator: headerGenerator,\n\t}\n\n\tfileInfo, err := os.Stat(absPath)\n\tif err == nil && rotateIfExists { \/\/ err == nil means file exists\n\t\treturn appender, appender.rotate()\n\t} else {\n\t\t\/\/ we're either creating a new log file or appending to the current one\n\t\tappender.file, err = os.OpenFile(\n\t\t\tabsPath,\n\t\t\tos.O_WRONLY|os.O_APPEND|os.O_CREATE,\n\t\t\t0666,\n\t\t)\n\t\tif err != nil {\n\t\t\treturn nil, err\n\t\t}\n\n\t\tif fileInfo != nil {\n\t\t\tappender.curFileSize = fileInfo.Size()\n\t\t}\n\n\t\treturn appender, appender.logHeader()\n\t}\n}\n\nfunc (self *RollingFileAppender) Append(log *slogger.Log) error {\n\tn, err := self.appendSansSizeTracking(log)\n\tself.curFileSize += int64(n)\n\n\tif err != nil {\n\t\treturn err\n\t}\n\n\tif self.MaxFileSize > 0 && self.curFileSize > self.MaxFileSize {\n\t\treturn self.rotate()\n\t}\n\n\treturn nil\n}\n\nfunc (self *RollingFileAppender) Close() error {\n\terr := self.Flush()\n\tif err != nil {\n\t\treturn err\n\t}\n\treturn self.file.Close()\n}\n\nfunc (self *RollingFileAppender) Flush() error {\n\treturn self.file.Sync()\n}\n\nfunc rotatedFilename(baseFilename string, t time.Time, serial int) string {\n\tfilename := fmt.Sprintf(\n\t\t\"%s.%d-%02d-%02dT%02d-%02d-%02d\",\n\t\tbaseFilename,\n\t\tt.Year(),\n\t\tt.Month(),\n\t\tt.Day(),\n\t\tt.Hour(),\n\t\tt.Minute(),\n\t\tt.Second(),\n\t)\n\n\tif serial > 0 {\n\t\tfilename = fmt.Sprintf(\"%s-%d\", filename, serial)\n\t}\n\n\treturn filename\n}\n\nfunc (self *RollingFileAppender) appendSansSizeTracking(log *slogger.Log) (bytesWritten int, err error) {\n\tif self.file == nil {\n\t\treturn 0, NoFileError{}\n\t}\n\n\tmsg := slogger.FormatLog(log)\n\tbytesWritten, err = self.file.WriteString(msg)\n\n\tif err != nil {\n\t\terr = WriteError{self.absPath, err}\n\t}\n\n\treturn\n}\n\nfunc (self *RollingFileAppender) logHeader() error {\n\theader := self.headerGenerator()\n\tfor _, line := range header {\n\n\t\tlog := &slogger.Log{\n\t\t\tPrefix:     \"header\",\n\t\t\tLevel:      slogger.INFO,\n\t\t\tFilename:   \"\",\n\t\t\tLine:       0,\n\t\t\tTimestamp:  time.Now(),\n\t\t\tMessageFmt: line,\n\t\t\tArgs:       []interface{}{},\n\t\t}\n\n\t\t\/\/ do not count header as part of size towards rotation in\n\t\t\/\/ order to prevent infinite rotation when max size is smaller\n\t\t\/\/ than header\n\t\t_, err := self.appendSansSizeTracking(log)\n\t\tif err != nil {\n\t\t\treturn err\n\t\t}\n\t}\n\n\treturn nil\n}\n\nfunc (self *RollingFileAppender) removeMaxRotatedLogs() error {\n\trotationTimes, err := self.rotationTimeSlice()\n\n\tif err != nil {\n\t\treturn MinorRotationError{err}\n\t}\n\n\tnumLogsToDelete := len(rotationTimes) - self.MaxRotatedLogs\n\n\t\/\/ return if we're under the limit\n\tif numLogsToDelete <= 0 {\n\t\treturn nil\n\t}\n\n\t\/\/ otherwise remove enough of the oldest logfiles to bring us\n\t\/\/ under the limit\n\tsort.Sort(rotationTimes)\n\tfor _, rotationTime := range rotationTimes[:numLogsToDelete] {\n\t\tif err = os.Remove(rotationTime.Filename);

The Session is built from the SDK's default configuration and\nrequest handlers.\n\nSessions should be cached when possible, because creating a new Session will\nload all configuration values from the environment, and config files each time\nthe Session is created. Sharing the Session value across all of your service\nclients will ensure the configuration is loaded the fewest number of times possible.\n\nConcurrency\n\nSessions are safe to use concurrently as long as the Session is not being\nmodified. The SDK will not modify the Session once the Session has been created.\nCreating service clients concurrently from a shared Session is safe.\n\nSessions from Shared Config\n\nSessions can be created using the method above that will only load the\nadditional config if the AWS_SDK_LOAD_CONFIG environment variable is set.\nAlternatively you can explicitly create a Session with shared config enabled.\nTo do this you can use NewSessionWithOptions to configure how the Session will\nbe created. Using the NewSessionWithOptions with SharedConfigState set to\nSharedConfigEnable will create the session as if the AWS_SDK_LOAD_CONFIG\nenvironment variable was set.\n\nCreating Sessions\n\nWhen creating Sessions optional aws.Config values can be passed in that will\noverride the default, or loaded config values the Session is being created\nwith. This allows you to provide additional, or case based, configuration\nas needed.\n\nBy default NewSession will only load credentials from the shared credentials\nfile (~\/.aws\/credentials). If the AWS_SDK_LOAD_CONFIG environment variable is\nset to a truthy value the Session will be created from the configuration\nvalues from the shared config (~\/.aws\/config) and shared credentials\n(~\/.aws\/credentials) files. See the section Sessions from Shared Config for\nmore information.\n\nCreate a Session with the default config and request handlers.

All service\nclients that use the session inherit the handlers. For example, the following\nhandler logs every request and its payload made by a service client:\n\n\t\/\/ Create a session, and add additional handlers for all service\n\t\/\/ clients created with the Session to inherit.

This includes credentials, region, and support for assume role. In\naddition the Session will load its configuration from both the shared config\nfile (~\/.aws\/config) and shared credentials file (~\/.aws\/credentials). Both\nfiles have the same format.\n\nIf both config files are present the configuration from both files will be\nread.

All environment values are optional, but some values like credentials\nrequire multiple of the values to set or the partial values will be ignored.\nAll environment variable values are strings unless otherwise noted.\n\nEnvironment configuration values.

This also enables\nRegion and Profile support for the AWS_DEFAULT_REGION and AWS_DEFAULT_PROFILE\nenv values as well.\n\n\tAWS_SDK_LOAD_CONFIG=1\n\nShared credentials file path can be set to instruct the SDK to use an alternative\nfile for the shared credentials.

Use this only\nif you want to replace the CA bundle the SDK uses for TLS requests.\n\n\tAWS_CA_BUNDLE=$HOME\/my_custom_ca_bundle\n\nEnabling this option will attempt to merge the Transport into the SDK's HTTP\nclient. If the client's Transport is not a http.Transport an error will be\nreturned. If the Transport's TLS config is set this option will cause the SDK\nto overwrite the Transport's TLS config's  RootCAs value. If the CA bundle file\ncontains multiple certificates all of them will be loaded.\n\nThe Session option CustomCABundle is also available when creating sessions\nto also enable this feature. CustomCABundle session option field has priority\nover the AWS_CA_BUNDLE environment variable, and will be used if both are set.\n\nSetting a custom HTTPClient in the aws.Config options will override this setting.\nTo use this option and custom HTTP client, the HTTP client needs to be provided\nwhen creating the session.

If not set the file will be loaded from\n$HOME\/.aws\/credentials on Linux\/Unix based systems, and\n%USERPROFILE%\\.aws\\credentials on Windows.\n\n\tAWS_SHARED_CREDENTIALS_FILE=$HOME\/my_shared_credentials\n\nShared config file path can be set to instruct the SDK to use an alternative\nfile for the shared config.

Use this only\nif you want to replace the CA bundle the SDK uses for TLS requests.\n\n\tAWS_CA_BUNDLE=$HOME\/my_custom_ca_bundle\n\nEnabling this option will attempt to merge the Transport into the SDK's HTTP\nclient. If the client's Transport is not a http.Transport an error will be\nreturned. If the Transport's TLS config is set this option will cause the SDK\nto overwrite the Transport's TLS config's  RootCAs value. If the CA bundle file\ncontains multiple certificates all of them will be loaded.\n\nThe Session option CustomCABundle is also available when creating sessions\nto also enable this feature. CustomCABundle session option field has priority\nover the AWS_CA_BUNDLE environment variable, and will be used if both are set.\n\nSetting a custom HTTPClient in the aws.Config options will override this setting.\nTo use this option and custom HTTP client, the HTTP client needs to be provided\nwhen creating the session.

To avoid\n\trecursion in cases such as\n\t\ttype X int\n\t\tfunc (x X) String() string { return Sprintf(\"%d\", x) }\n\tcast the value before recurring:\n\t\tfunc (x X) String() string { return Sprintf(\"%d\", int(x)) }\n\n\tFormat errors:\n\n\tIf an invalid argument is given for a verb, such as providing\n\ta string to %d, the generated string will contain a\n\tdescription of the problem, as in these examples:\n\n\t\tWrong type or unknown verb: %!verb(type=value)\n\t\t\tPrintf(\"%d\", hi):          %!d(string=hi)\n\t\tToo many arguments: %!(EXTRA type=value)\n\t\t\tPrintf(\"hi\", \"guys\"):      hi%!(EXTRA string=guys)\n\t\tToo few arguments: %!verb(MISSING)\n\t\t\tPrintf(\"hi%d\"):            hi %!d(MISSING)\n\t\tNon-int for width or precision: %!(BADWIDTH) or %!(BADPREC)\n\t\t\tPrintf(\"%*s\", 4.5, \"hi\"):  %!(BADWIDTH)hi\n\t\t\tPrintf(\"%.*s\", 4.5, \"hi\"): %!(BADPREC)hi\n\n\tAll errors begin with the string \"%!\" followed sometimes\n\tby a single character (the verb) and end with a parenthesized\n\tdescription.\n\n\tScanning:\n\n\tAn analogous set of functions scans formatted text to yield\n\tvalues.  Scan, Scanf and Scanln read from os.Stdin; Fscan,\n\tFscanf and Fscanln read from a specified os.Reader; Sscan,\n\tSscanf and Sscanln read from an argument string.  Sscanln,\n\tFscanln and Sscanln stop scanning at a newline and require that\n\tthe items be followed by one; Sscanf, Fscanf and Sscanf require\n\tnewlines in the input to match newlines in the format; the other\n\troutines treat newlines as spaces.\n\n\tScanf, Fscanf, and Sscanf parse the arguments according to a\n\tformat string, analogous to that of Printf.  For example, %x\n\twill scan an integer as a hexadecimal number, and %v will scan\n\tthe default representation format for the value.\n\n\tThe formats behave analogously to those of Printf with the\n\tfollowing exceptions:\n\n\t%p is not implemented\n\t%T is not implemented\n\t%e %E %f %F %g %g are all equivalent and scan any floating point or complex value\n\t%s and %v on strings scan a space-delimited token\n\n\tWidth is interpreted in the input text (%5s means at most\n\tfive runes of input will be read to scan a string) but there\n\tis no syntax for scanning with a precision (no %5.2f, just\n\t%5f).\n\n\tWhen scanning with a format, all non-empty runs of space\n\tcharacters (except newline) are equivalent to a single\n\tspace in both the format and the input.  With that proviso,\n\ttext in the format string must match the input text; scanning\n\tstops if it does not, with the return value of the function\n\tindicating the number of arguments scanned.\n\n\tIn all the scanning functions, if an operand implements method\n\tScan (that is, it implements the Scanner interface) that\n\tmethod will be used to scan the text for that operand.  Also,\n\tif the number of arguments scanned is less than the number of\n\targuments provided, an error is returned.\n\n\tAll arguments to be scanned must be either pointers to basic\n\ttypes or implementations of the Scanner interface.\n\n\tNote: Fscan etc. can read one character (rune) past the\n\tinput they return, which means that a loop calling a scan\n\troutine may skip some of the input.  This is usually a\n\tproblem only when there is no space between input values.\n\tHowever, if the reader provided to Fscan implements UnreadRune,\n\tthat method will be used to save the character and successive\n\tcalls will not lose data.  To attach an UnreadRune method\n\tto a reader without that capability, use bufio.NewReader.\n*\/\npackage fmt\n<commit_msg>fmt: document %%<commit_after>\/\/ Copyright 2009 The Go Authors.

Another variant Println inserts blanks between\n\toperands and appends a newline.\n\n\tRegardless of the verb, if an operand is an interface value,\n\tthe internal concrete value is used, not the interface itself.\n\tThus:\n\t\tvar i interface{} = 23\n\t\tfmt.Printf(\"%v\\n\", i)\n\twill print 23.\n\n\tIf an operand implements interface Formatter, that interface\n\tcan be used for fine control of formatting.\n\n\tIf an operand implements method String() string that method\n\twill be used to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any). To avoid\n\trecursion in cases such as\n\t\ttype X int\n\t\tfunc (x X) String() string { return Sprintf(\"%d\", x) }\n\tcast the value before recurring:\n\t\tfunc (x X) String() string { return Sprintf(\"%d\", int(x)) }\n\n\tFormat errors:\n\n\tIf an invalid argument is given for a verb, such as providing\n\ta string to %d, the generated string will contain a\n\tdescription of the problem, as in these examples:\n\n\t\tWrong type or unknown verb: %!verb(type=value)\n\t\t\tPrintf(\"%d\", hi):          %!d(string=hi)\n\t\tToo many arguments: %!(EXTRA type=value)\n\t\t\tPrintf(\"hi\", \"guys\"):      hi%!(EXTRA string=guys)\n\t\tToo few arguments: %!verb(MISSING)\n\t\t\tPrintf(\"hi%d\"):            hi %!d(MISSING)\n\t\tNon-int for width or precision: %!(BADWIDTH) or %!(BADPREC)\n\t\t\tPrintf(\"%*s\", 4.5, \"hi\"):  %!(BADWIDTH)hi\n\t\t\tPrintf(\"%.*s\", 4.5, \"hi\"): %!(BADPREC)hi\n\n\tAll errors begin with the string \"%!\" followed sometimes\n\tby a single character (the verb) and end with a parenthesized\n\tdescription.\n\n\tScanning:\n\n\tAn analogous set of functions scans formatted text to yield\n\tvalues.  Scan, Scanf and Scanln read from os.Stdin; Fscan,\n\tFscanf and Fscanln read from a specified os.Reader; Sscan,\n\tSscanf and Sscanln read from an argument string.  Sscanln,\n\tFscanln and Sscanln stop scanning at a newline and require that\n\tthe items be followed by one; Sscanf, Fscanf and Sscanf require\n\tnewlines in the input to match newlines in the format; the other\n\troutines treat newlines as spaces.\n\n\tScanf, Fscanf, and Sscanf parse the arguments according to a\n\tformat string, analogous to that of Printf.  For example, %x\n\twill scan an integer as a hexadecimal number, and %v will scan\n\tthe default representation format for the value.\n\n\tThe formats behave analogously to those of Printf with the\n\tfollowing exceptions:\n\n\t%p is not implemented\n\t%T is not implemented\n\t%e %E %f %F %g %g are all equivalent and scan any floating point or complex value\n\t%s and %v on strings scan a space-delimited token\n\n\tWidth is interpreted in the input text (%5s means at most\n\tfive runes of input will be read to scan a string) but there\n\tis no syntax for scanning with a precision (no %5.2f, just\n\t%5f).\n\n\tWhen scanning with a format, all non-empty runs of space\n\tcharacters (except newline) are equivalent to a single\n\tspace in both the format and the input.  With that proviso,\n\ttext in the format string must match the input text; scanning\n\tstops if it does not, with the return value of the function\n\tindicating the number of arguments scanned.\n\n\tIn all the scanning functions, if an operand implements method\n\tScan (that is, it implements the Scanner interface) that\n\tmethod will be used to scan the text for that operand.  Also,\n\tif the number of arguments scanned is less than the number of\n\targuments provided, an error is returned.\n\n\tAll arguments to be scanned must be either pointers to basic\n\ttypes or implementations of the Scanner interface.\n\n\tNote: Fscan etc. can read one character (rune) past the\n\tinput they return, which means that a loop calling a scan\n\troutine may skip some of the input.  This is usually a\n\tproblem only when there is no space between input values.\n\tHowever, if the reader provided to Fscan implements UnreadRune,\n\tthat method will be used to save the character and successive\n\tcalls will not lose data.  To attach an UnreadRune method\n\tto a reader without that capability, use bufio.NewReader.\n*\/\npackage fmt\n<|endoftext|>"}

be optional in which case they can be specified positionally or via keys if you want to specify params that come after un-specified optional params\n\t\/\/ the val pointers of each input Arg should

shall affect series[list] parameters)\n\t\/\/ examples:\n\t\/\/ * movingAverage(foo,5min) -> the 5min arg will be parsed, so we can request 5min of earlier data, which will affect the request for foo.\n\t\/\/ * consolidateBy(bar, \"sum\") -> the \"sum\" arg will be parsed, so we can pass on the fact that bar needs to be sum-consolidated\n\tContext(c Context) Context\n\t\/\/ Exec executes the

But what happens to elements equal to\n    the partitioning value? Hoare’s partitioning method is\n    binary: it places lesser elements on the left and greater elements\n    on the right, but equal elements may appear on\n    either side.\n\n    Algorithm designers have long recognized the desirability\n    and difficulty of a ternary partitioning method.\n    Sedgewick [22] observes on page 244: ‘‘Ideally, we would\n    like to get all [equal keys] into position in the file, with all\n    the keys with a smaller value to their left, and all the keys\n    with a larger value to their right. Unfortunately, no\n    efficient method for doing so has yet been devised....’’\n    Dijkstra [6] popularized this as ‘‘The Problem of the Dutch\n    National Flag’’: we are to order a sequence of red, white\n    and blue pebbles to appear in their order on Holland’s\n    ensign. This corresponds to Quicksort partitioning when\n    lesser elements are colored red, equal elements are white,\n    and greater elements are blue. Dijkstra’s ternary algorithm\n    requires linear time (it looks at each element exactly once),\n    but code to implement it has a significantly larger constant\n    factor than Hoare’s binary partitioning code.\n\n    Wegner [27] describes more efficient ternary partitioning\n    schemes. Bentley and McIlroy [2] present a ternary\n    partition based on this counterintuitive loop invariant:\n\n    The main partitioning loop has two inner loops. The first\n    inner loop moves up the index b: it scans over lesser elements,\n    swaps equal elements to a, and halts on a greater\n    element. The second inner loop moves down the index c\n    correspondingly: it scans over greater elements, swaps\n    equal elements to d, and halts on a lesser element. The\n    main loop then swaps the elements pointed to by b and c,\n    increments b and decrements c, and continues until b and\n    c cross. (Wegner proposed the same invariant, but maintained\n    it with more complex code.) Afterwards, the equal\n    elements on the edges are swapped to the middle of the\n    array, without any extraneous comparisons. This code partitions\n    an n-element array using n − 1 comparisons\n\n    Quicksort has been extensively analyzed by authors\n    including Hoare [9], van Emden [26], Knuth [11], and\n    Sedgewick [23]. Most detailed analyses involve the harmonic\n    numbers Hn = Σ 1≤i≤n 1\/ i.\n\n    Theorem 1.

But what happens to elements equal to\n    the partitioning value? Hoare’s partitioning method is\n    binary: it places lesser elements on the left and greater elements\n    on the right, but equal elements may appear on\n    either side.\n\n    Algorithm designers have long recognized the desirability\n    and difficulty of a ternary partitioning method.\n    Sedgewick [22] observes on page 244: ‘‘Ideally, we would\n    like to get all [equal keys] into position in the file, with all\n    the keys with a smaller value to their left, and all the keys\n    with a larger value to their right. Unfortunately, no\n    efficient method for doing so has yet been devised....’’\n    Dijkstra [6] popularized this as ‘‘The Problem of the Dutch\n    National Flag’’: we are to order a sequence of red, white\n    and blue pebbles to appear in their order on Holland’s\n    ensign. This corresponds to Quicksort partitioning when\n    lesser elements are colored red, equal elements are white,\n    and greater elements are blue. Dijkstra’s ternary algorithm\n    requires linear time (it looks at each element exactly once),\n    but code to implement it has a significantly larger constant\n    factor than Hoare’s binary partitioning code.\n\n    Wegner [27] describes more efficient ternary partitioning\n    schemes. Bentley and McIlroy [2] present a ternary\n    partition based on this counterintuitive loop invariant:\n\n    The main partitioning loop has two inner loops. The first\n    inner loop moves up the index b: it scans over lesser elements,\n    swaps equal elements to a, and halts on a greater\n    element. The second inner loop moves down the index c\n    correspondingly: it scans over greater elements, swaps\n    equal elements to d, and halts on a lesser element. The\n    main loop then swaps the elements pointed to by b and c,\n    increments b and decrements c, and continues until b and\n    c cross. (Wegner proposed the same invariant, but maintained\n    it with more complex code.) Afterwards, the equal\n    elements on the edges are swapped to the middle of the\n    array, without any extraneous comparisons. This code partitions\n    an n-element array using n − 1 comparisons\n\n    Quicksort has been extensively analyzed by authors\n    including Hoare [9], van Emden [26], Knuth [11], and\n    Sedgewick [23]. Most detailed analyses involve the harmonic\n    numbers Hn = Σ 1≤i≤n 1\/ i.\n\n    Theorem 1. [Hoare] A Quicksort that partitions\n    around a single randomly selected element sorts n distinct\n    items in 2nHn + O(n) ∼∼ 1. 386n lg n expected\n    comparisons.\n\n    A common variant of Quicksort partitions around the\n    median of a random sample.\n\n    Theorem 2. [van Emden] A Quicksort that partitions\n    around the median of 2t + 1 randomly selected elements\n    sorts n distinct items in 2nHn \/ (H2t + 2 − Ht + 1 )\n    + O(n) expected comparisons.\n    By increasing t, we can push the expected number of comparisons\n    close to n lg n + O(n).\n    `)\n<|endoftext|>"}

plugin\n\/\/ JSON is a formatter that passes a message encapsulated as JSON in the form\n\/\/ {\"message\":\"...\"}. The actual message is formatted by a nested formatter and\n\/\/ HTML escaped.\n\/\/ Configuration example\n\/\/\n\/\/  - \"stream.Broadcast\":\n\/\/    Formatter: \"format.JSON\"\n\/\/    JSONStartState: \"findKey\"\n\/\/    JSONDirectives:\n\/\/\t    - 'findKey :\":  key     ::'\n\/\/\t    - 'findKey :}:          : pop  : end'\n\/\/\t    - 'key     :\":  findVal :      : key'\n\/\/\t    - 'findVal :\\:: value   ::'\n\/\/\n\/\/ JSONStartState defines the initial parser state when parsing a message.\n\/\/ By default this is set to \"\" which will fall back to the first state used in\n\/\/ the JSONDirectives array.\n\/\/\n\/\/ JSONTimestampRead defines the go timestamp format expected from fields that\n\/\/ are parsed as \"dat\". By default this is set to \"20060102150405\".\n\/\/\n\/\/ JSONTimestampWrite defines the go timestamp format that \"dat\" fields will be\n\/\/ converted to. By default this is set to \"2006-01-02 15:04:05 MST\".\n\/\/\n\/\/ JSONDirectives defines an array of parser directives.\n\/\/ This setting is mandatory and has no default value.\n\/\/ Each string must be of the following format: \"State:Token:NextState:Flags:Function\".\n\/\/ Spaces will be stripped from all fields but Token. If a fields requires a\n\/\/ colon it has to be escaped with a backslash. Other escape characters\n\/\/ supported are \\n, \\r and \\t.\n\/\/\n\/\/ Flags (JSONDirectives) can be a comma separated set of the following flags.\n\/\/  * continue -> Prepend the token to the next match.\n\/\/  * append   -> Append the token to the current match and continue reading.\n\/\/  * include  -> Append the token to the current match.\n\/\/  * push     -> Push the current state to the stack.\n\/\/  * pop      -> Pop the stack and use the returned state if possible.\n\/\/\n\/\/ Function (JSONDirectives) can hold one of the following names.\n\/\/  * key     -> Write the current match as a key.\n\/\/  * val     -> Write the current match as a value without quotes.\n\/\/  * esc     -> Write the current match as a escaped string value.\n\/\/  * dat     -> Write the current match as a timestamp value.\n\/\/  * arr     -> Start a new array.\n\/\/  * obj     -> Start a new object.\n\/\/  * end     -> Close an array or object.\n\/\/  * arr+val -> arr followed by val.\n\/\/  * arr+esc -> arr followed by esc.\n\/\/  * arr+dat -> arr followed by dat.\n\/\/  * val+end -> val followed by end.\n\/\/  * esc+end -> esc followed by end.\n\/\/  * dat+end -> dat followed by end.\n\/\/\n\/\/ Rules for storage (JSONDirectives): if a value is written without a previous key write, a key will be auto\n\/\/ generated from the current parser state name. This does not happen when\n\/\/ inside an array.\n\/\/ If key is written without a previous value write, a null value will be\n\/\/ written. This does not happen after an object has been started.\n\/\/ A key write inside an array will cause the array to be closed. If the array\n\/\/ is nested, all arrays will be closed.\ntype JSON struct {\n\tmessage   *bytes.Buffer\n\tparser    shared.TransitionParser\n\tstate     jsonReaderState\n\tstack

{"text":"<commit_before>\/*\nPackage channels provides a collection of helper functions, interfaces and implementations for\nworking with and extending the capabilities of golang's existing channels. The main interface of\ninterest is Channel, though sub-interfaces are also provided for cases where the full Channel interface\ncannot be met (for example, InChannel for write-only channels).\n\nFor integration with native typed golang channels, functions Wrap and Unwrap are provided which do the\nappropriate type conversions. The NativeChannel, NativeInChannel and NativeOutChannel type definitions\nare also provided for use with native channels which already carry values of type interface{}.\n\nThe heart of the package consists of several distinct implementations of the Channel interface, including\nchannels backed by special buffers (resizable, infinite, ring buffers, etc) and other useful types. A\n\"black hole\" channel for discarding unwanted values (similar in purpose to ioutil.Discard or \/dev\/null)\nrounds out the set.\n\nHelper functions for operating on Channels include Pipe and Tee (which behave much like their Unix\nnamesakes), as well as Multiplex and Distribute. \"Weak\" versions of these functions also exist, which\ndo not close their output channel(s) on completion.\n\nWarning: several types in this package provide so-called \"infinite\" buffers.

The NativeChannel, NativeInChannel and NativeOutChannel type definitions\nare also provided for use with native channels which already carry values of type interface{}.\n\nThe heart of the package consists of several distinct implementations of the Channel interface, including\nchannels backed by special buffers (resizable, infinite, ring buffers, etc) and other useful types. A\n\"black hole\" channel for discarding unwanted values (similar in purpose to ioutil.Discard or \/dev\/null)\nrounds out the set.\n\nHelper functions for operating on Channels include Pipe and Tee (which behave much like their Unix\nnamesakes), as well as Multiplex and Distribute. \"Weak\" versions of these functions also exist, which\ndo not close their output channel(s) on completion.\n\nWarning: several types in this package provide so-called \"infinite\" buffers.

If your search query\n   for artifacts matches multiple agents, and error will be raised.\n\n   Note: You need to ensure that your search query is surrounded by quotes if\n   using a wild card as the built-in shell path globbing will provide files,\n   which will break the download.\n\nExample:\n\n   $ buildkite-agent artifact shasum \"pkg\/release.tar.gz\" --build xxx\n\n   This will search for all the files in the build with the path \"pkg\/release.tar.gz\" and will\n   print to STDOUT it's SHA-1 checksum.\n\n   If you would like to target artifacts from a specific build step, you can do\n   so by using the --job argument.\n\n   $ buildkite-agent artifact shasum \"pkg\/release.tar.gz\" --job \"release\" --build xxx\n\n   You can also use the job's id (provided by the environment variable $BUILDKITE_JOB_ID)`\n\nvar DownloadHelpDescription = `Usage:\n\n   buildkite-agent artifact download [arguments...]\n\nDescription:\n\n   Downloads artifacts from Buildkite to the local machine.\n\n   Note: You need to ensure that your search query is surrounded by quotes if\n   using a wild card as the built-in shell path globbing will provide files,\n   which will break the download.\n\nExample:\n\n   $ buildkite-agent artifact download \"pkg\/*.tar.gz\" . --build xxx\n\n   This will search across all the artifacts for the build with files that match that part.\n   The first argument is the search query, and the second argument is the download destination.\n\n   If you're trying to download a specific file, and there are multiple artifacts from different\n   jobs, you can target the particular job you want to download the artifact from:\n\n   $ buildkite-agent artifact download \"pkg\/*.tar.gz\" . --job \"tests\" --build xxx\n\n   You can also use the job's id (provided by the environment variable $BUILDKITE_JOB_ID)`\n\nvar UploadHelpDescription = `Usage:\n\n   buildkite-agent artifact upload <pattern> <destination> [arguments...]\n\nDescription:\n\n   Uploads files to a job as artifacts.\n\n   You need to ensure that the paths are surrounded by quotes otherwise the\n   built-in shell path globbing will provide the files, which is currently not\n   supported.\n\nExample:\n\n   $ buildkite-agent artifact upload \"log\/**\/*.log\"\n\n   You can also upload directly to Amazon S3 if you'd like to host your own artifacts:\n\n   $ export

[arguments...]\n\nDescription:\n\n   When a job is ready to run it will call the \"bootstrap-script\"\n   and pass it all the environment variables required for the job to run.\n   This script is responsible for checking out the code, and running the\n   actual build script defined in the project.\n\n   The agent will run any jobs within a PTY (pseudo terminal) if available.\n\nExample:\n\n   $ buildkite-agent start --token xxx`\n\nvar ShasumHelpDescription = `Usage:\n\n   buildkite-agent artifact shasum [arguments...]\n\nDescription:\n\n   Prints to STDOUT the SHA-1 for the artifact provided. If your search query\n   for artifacts matches multiple agents, and error will be raised.\n\n   Note: You need to ensure that your search query is surrounded by quotes if\n   using a wild card as the built-in shell path globbing will provide files,\n   which will break the download.\n\nExample:\n\n   $ buildkite-agent artifact shasum \"pkg\/release.tar.gz\" --build xxx\n\n   This will search for all the files in the build with the path \"pkg\/release.tar.gz\" and will\n   print to STDOUT it's SHA-1 checksum.\n\n   If you would like to target artifacts from a specific build step, you can do\n   so by using the --job argument.\n\n   $ buildkite-agent artifact shasum \"pkg\/release.tar.gz\" --job \"release\" --build xxx\n\n   You can also use the job's id (provided by the environment variable $BUILDKITE_JOB_ID)`\n\nvar DownloadHelpDescription = `Usage:\n\n   buildkite-agent artifact download [arguments...]\n\nDescription:\n\n   Downloads artifacts from Buildkite to the local machine.\n\n   Note: You need to ensure that your search query is surrounded by quotes if\n   using a wild card as the built-in shell path globbing will provide files,\n   which will break the download.\n\nExample:\n\n   $ buildkite-agent artifact download \"pkg\/*.tar.gz\" . --build xxx\n\n   This will search across all the artifacts for the build with files that match that part.\n   The first argument is the search query, and the second argument is the download destination.\n\n   If you're trying to download a specific file, and there are multiple artifacts from different\n   jobs, you can target the particular job you want to download the artifact from:\n\n   $ buildkite-agent artifact download \"pkg\/*.tar.gz\" . --job \"tests\" --build xxx\n\n   You can also use the job's id (provided by the environment variable $BUILDKITE_JOB_ID)`\n\nvar UploadHelpDescription = `Usage:\n\n   buildkite-agent artifact upload <pattern> <destination> [arguments...]\n\nDescription:\n\n   Uploads files to a job as artifacts.\n\n   You need to ensure that the paths are surrounded by quotes otherwise the\n   built-in shell path globbing will provide the files, which is currently not\n   supported.\n\nExample:\n\n   $ buildkite-agent artifact upload \"log\/**\/*.log\"\n\n   You can also upload directly to Amazon S3 if you'd like to host your own artifacts:\n\n   $ export BUILDKITE_S3_ACCESS_KEY_ID=xxx\n   $ export BUILDKITE_S3_SECRET_ACCESS_KEY=yyy\n   $ export BUILDKITE_S3_DEFAULT_REGION=eu-central-1 # default is us-east-1\n   $ export BUILDKITE_S3_ACL=private # default is public-read\n   $ buildkite-agent artifact upload \"log\/**\/*.log\" s3:\/\/name-of-your-s3-bucket\/$BUILDKITE_JOB_ID`\n\nvar SetHelpDescription = `Usage:\n\n   buildkite-agent meta-data set <key> <value> [arguments...]\n\nDescription:\n\n   Set arbitrary data on a build using a basic key\/value store.\n\nExample:\n\n   $ buildkite-agent meta-data set \"foo\" \"bar\"`\n\nvar GetHelpDescription = `Usage:\n\n   buildkite-agent meta-data get <key> [arguments...]\n\nDescription:\n\n   Get data from a builds key\/value store.\n\nExample:\n\n   $ buildkite-agent meta-data get
