The first counter input word is set to one and the plaintext\n\/\/     is encrypted by XORing it with the output of invocations of the ChaCha20\n\/\/     function as needed, incrementing the first counter word after each block\n\/\/     and overflowing into the second.  (In the case of the TLS, limits on the\n\/\/     plaintext size mean that the first counter word will never overflow in\n\/\/     practice.)\n\/\/\n\/\/     The Poly1305 key is used to calculate a tag for the following input: the\n\/\/     concatenation of the number of bytes of additional data, the additional\n\/\/     data itself, the number of bytes of ciphertext and the ciphertext\n\/\/     itself. Numbers are represented as 8-byte, little-endian values.  The\n\/\/     resulting tag is appended to the ciphertext, resulting in the output of\n\/\/     the AEAD operation.\n\/\/\n\/\/ (http:\/\/tools.ietf.org\/html\/draft-agl-tls-chacha20poly1305-04)\n\/\/\n\/\/ The AEAD (Athenticated Encryption with Associated Data) construction provides\n\/\/ a unified API for sealing messages in a way which provides both\n\/\/ confidentiality *and* integrity.

The index is the\nfile named by $CSEARCHINDEX, or else $HOME\/.csearchindex.\n\nThe simplest invocation is\n\n\tcindex path...\n\nwhich adds the file or directory tree named by each path to the index.\nFor example:\n\n\tcindex $HOME\/src \/usr\/include\n\nor, equivalently:\n\n\tcindex $HOME\/src\n\tcindex \/usr\/include\n\nIf cindex is invoked with no paths, it reindexes the paths that have\nalready been added, in case the files have changed.  Thus, 'cindex' by\nitself is a useful command to run in a nightly cron job.\n\nBy default cindex adds the named paths to the index but preserves\ninformation about other paths that might already be indexed\n(the ones printed by cindex -list).  The -reset flag causes cindex to\ndelete the existing index before indexing the new paths.\nWith no path arguments, cindex -reset removes the index.\n`\n\nfunc usage() {\n\tfmt.Fprintf(os.Stderr, usageMessage, DEFAULT_MAX_FILE_LENGTH, DEFAULT_MAX_LINE_LENGTH, DEFAULT_MAX_TEXT_TRIGRAMS, DEFAULT_MAX_INVALID_UTF8_PERCENTAGE)\n\tos.Exit(2)\n}\n\nvar (\n\tlistFlag             = flag.Bool(\"list\",               false,               \"list indexed paths and exit\")\n\tresetFlag            = flag.Bool(\"reset\",              false,               \"discard existing index\")\n\tverboseFlag          = flag.Bool(\"verbose\",            false,               \"print extra information\")\n\tcpuProfile           = flag.String(\"cpuprofile\",       \"\",                  \"write cpu profile to this file\")\n\tindexPath            = flag.String(\"indexpath\",        \"\",                  \"specifies index path\")\n\tlogSkipFlag          = flag.Bool(\"logskip\",            false,               \"print why a file was skipped from indexing\")\n\tnoFollowSymlinksFlag = flag.Bool(\"no-follow-symlinks\", true,                \"do not follow symlinked files and directories\")\n\texclude              = flag.String(\"exclude\",          \"~\/.csearchexclude\", \"path to file containing a list of path regexp patterns to exclude from indexing\")\n\t\/\/ Tuning variables for detecting text files.\n\t\/\/ A file is assumed not to be text files (and thus not indexed) if\n\t\/\/ 1) if it contains an invalid UTF-8 sequences\n\t\/\/ 2) if it is longer than maxFileLength bytes\n\t\/\/ 3) if it contains a line longer than maxLineLen bytes,\n\t\/\/ or\n\t\/\/ 4) if it contains more than maxTextTrigrams distinct trigrams.\n\tmaxFileLen          = flag.Int64(\"maxfilelen\", DEFAULT_MAX_FILE_LENGTH, \"skip indexing a file if longer than this size in bytes\")\n\tmaxLineLen          = flag.Int(\"maxlinelen\", DEFAULT_MAX_LINE_LENGTH, \"skip indexing a file if it has a line longer than this size in bytes\")\n\tmaxTextTrigrams     = flag.Int(\"maxtrigrams\", DEFAULT_MAX_TEXT_TRIGRAMS, \"skip indexing a file if it has more than this number of trigrams\")\n\tmaxInvalidUTF8Ratio = flag.Float64(\"maxinvalidutf8ratio\", DEFAULT_MAX_INVALID_UTF8_PERCENTAGE, \"skip indexing a file if it has more than this ratio of invalid UTF-8 sequences\")\n\n\texcludePatterns = []string{\n\t\t\".csearchindex\",\n\t}\n)\n\nfunc walk(arg string, symlinkFrom string, out chan string, logskip bool) {\n\tfilepath.Walk(arg, func(path string, info os.FileInfo, err error) error {\n\t\tif basedir, elem := filepath.Split(path); elem != \"\" {\n\t\t\texclude := false\n\t\t\tfor _, pattern := range excludePatterns {\n\t\t\t\tif pattern != \"\" {\n\t\t\t\t\texclude, err = regexp.MatchString(pattern, path)\n\t\t\t\t\tif err != nil {\n\t\t\t\t\t\tlog.Fatal(err)\n\t\t\t\t\t}\n\t\t\t\t\tif exclude {\n\t\t\t\t\t\tbreak\n\t\t\t\t\t}\n\t\t\t\t}\n\t\t\t}\n\n\t\t\t\/\/ Skip various temporary or \"hidden\" files or directories.\n\t\t\tif info != nil && info.IsDir() {\n\t\t\t\tif exclude {\n\t\t\t\t\tif logskip {\n\t\t\t\t\t\tif symlinkFrom != \"\" {\n\t\t\t\t\t\t\tlog.Printf(\"%s: skipped.

The value of\n\/\/ the cookie is a signed JSON Web Token containing the original URL requested\n\/\/ and the SAML request ID. The random part of the name corresponds to the\n\/\/ RelayState parameter passed through the SAML flow.\n\/\/\n\/\/ When validating the SAML response, the RelayState is used to look up the\n\/\/ correct cookie, validate that the SAML request ID, and redirect the user\n\/\/ back to their original URL.\n\/\/\n\/\/ Sessions are established by issuing a JSON Web Token (JWT) as a session\n\/\/ cookie once the SAML flow has succeeded. The JWT token contains the\n\/\/ authenticated attributes from the SAML assertion.\n\/\/\n\/\/ When the middlware receives a request with a valid session JWT it extracts\n\/\/ the SAML attributes and modifies the http.Request object adding headers\n\/\/ corresponding to the specified attributes. For example, if the attribute\n\/\/ \"cn\" were present in the initial assertion with a value of \"Alice Smith\",\n\/\/ then a corresponding header \"X-Saml-Cn\" will be added to the request with\n\/\/ a value of \"Alice Smith\". For safety, the middleware strips out any existing\n\/\/ headers that begin with \"X-Saml-\".\n\/\/\n\/\/ When issuing JSON Web Tokens, a signing key is required. Because the\n\/\/ SAML service provider already has a private key, we borrow that key\n\/\/ to sign the JWTs as well.\ntype Middleware struct {\n\tServiceProvider   saml.ServiceProvider\n\tAllowIDPInitiated bool\n}\n\nconst cookieMaxAge = time.Hour \/\/ TODO(ross): must be configurable\nconst cookieName = \"token\"\n\nfunc randomBytes(n int) []byte {\n\trv := make([]byte, n)\n\tif _, err := saml.RandReader.Read(rv); err != nil {\n\t\tpanic(err)\n\t}\n\treturn rv\n}\n\n\/\/ ServeHTTP implements http.Handler and serves the SAML-specific HTTP endpoints\n\/\/ on the URIs specified by m.ServiceProvider.MetadataURL and\n\/\/ m.ServiceProvider.AcsURL.\nfunc (m *Middleware) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\tmetadataURL, _ := url.Parse(m.ServiceProvider.MetadataURL)\n\tif r.URL.Path == metadataURL.Path {\n\t\tbuf, _ := xml.MarshalIndent(saml.EntitiesDescriptor{\n\t\t\tEntityDescriptor: []*saml.Metadata{m.ServiceProvider.Metadata()},\n\t\t}, \"\", \"  \")\n\t\tw.Write(buf)\n\t\treturn\n\t}\n\n\tacsURL, _ := url.Parse(m.ServiceProvider.AcsURL)\n\tif r.URL.Path == acsURL.Path {\n\t\tr.ParseForm()\n\t\tassertion, err := m.ServiceProvider.ParseResponse(r, m.getPossibleRequestIDs(r))\n\t\tif err != nil {\n\t\t\tif parseErr, ok := err.(*saml.InvalidResponseError); ok {\n\t\t\t\tlog.Printf(\"RESPONSE: ===\\n%s\\n===\\nNOW: %s\\nERROR: %s\",\n\t\t\t\t\tparseErr.Response, parseErr.Now, parseErr.PrivateErr)\n\t\t\t}\n\t\t\thttp.Error(w, http.StatusText(http.StatusForbidden), http.StatusForbidden)\n\t\t\treturn\n\t\t}\n\n\t\tm.Authorize(w, r, assertion)\n\t\treturn\n\t}\n\n\thttp.NotFoundHandler().ServeHTTP(w, r)\n}\n\n\/\/ RequireAccount is HTTP middleware that requires that each request be\n\/\/ associated with a valid session.

The value of\n\/\/ the cookie is a signed JSON Web Token containing the original URL requested\n\/\/ and the SAML request ID. The random part of the name corresponds to the\n\/\/ RelayState parameter passed through the SAML flow.\n\/\/\n\/\/ When validating the SAML response, the RelayState is used to look up the\n\/\/ correct cookie, validate that the SAML request ID, and redirect the user\n\/\/ back to their original URL.\n\/\/\n\/\/ Sessions are established by issuing a JSON Web Token (JWT) as a session\n\/\/ cookie once the SAML flow has succeeded. The JWT token contains the\n\/\/ authenticated attributes from the SAML assertion.\n\/\/\n\/\/ When the middlware receives a request with a valid session JWT it extracts\n\/\/ the SAML attributes and modifies the http.Request object adding headers\n\/\/ corresponding to the specified attributes. For example, if the attribute\n\/\/ \"cn\" were present in the initial assertion with a value of \"Alice Smith\",\n\/\/ then a corresponding header \"X-Saml-Cn\" will be added to the request with\n\/\/ a value of \"Alice Smith\". For safety, the middleware strips out any existing\n\/\/ headers that begin with \"X-Saml-\".\n\/\/\n\/\/ When issuing JSON Web Tokens, a signing key is required. Because the\n\/\/ SAML service provider already has a private key, we borrow that key\n\/\/ to sign the JWTs as well.\ntype Middleware struct {\n\tServiceProvider   saml.ServiceProvider\n\tAllowIDPInitiated bool\n}\n\nconst cookieMaxAge = time.Hour \/\/ TODO(ross): must be configurable\nconst cookieName = \"token\"\n\nfunc randomBytes(n int) []byte {\n\trv := make([]byte, n)\n\tif _, err := saml.RandReader.Read(rv); err != nil {\n\t\tpanic(err)\n\t}\n\treturn rv\n}\n\n\/\/ ServeHTTP implements http.Handler and serves the SAML-specific HTTP endpoints\n\/\/ on the URIs specified by m.ServiceProvider.MetadataURL and\n\/\/ m.ServiceProvider.AcsURL.\nfunc (m *Middleware) ServeHTTP(w http.ResponseWriter, r *http.Request) {\n\tmetadataURL, _ := url.Parse(m.ServiceProvider.MetadataURL)\n\tif r.URL.Path == metadataURL.Path {\n\t\tbuf, _ := xml.MarshalIndent(saml.EntitiesDescriptor{\n\t\t\tEntityDescriptor: []*saml.Metadata{m.ServiceProvider.Metadata()},\n\t\t}, \"\", \"  \")\n\t\tw.Write(buf)\n\t\treturn\n\t}\n\n\tacsURL, _ := url.Parse(m.ServiceProvider.AcsURL)\n\tif r.URL.Path == acsURL.Path {\n\t\tr.ParseForm()\n\t\tassertion, err := m.ServiceProvider.ParseResponse(r, m.getPossibleRequestIDs(r))\n\t\tif err != nil {\n\t\t\tif parseErr, ok := err.(*saml.InvalidResponseError); ok {\n\t\t\t\tlog.Printf(\"RESPONSE: ===\\n%s\\n===\\nNOW: %s\\nERROR: %s\",\n\t\t\t\t\tparseErr.Response, parseErr.Now, parseErr.PrivateErr)\n\t\t\t}\n\t\t\thttp.Error(w, http.StatusText(http.StatusForbidden), http.StatusForbidden)\n\t\t\treturn\n\t\t}\n\n\t\tm.Authorize(w, r, assertion)\n\t\treturn\n\t}\n\n\thttp.NotFoundHandler().ServeHTTP(w, r)\n}\n\n\/\/ RequireAccount is HTTP middleware that requires that each request be\n\/\/ associated with a valid session.

This is the GNU\nmultiprecision library gmp's integer type mpz_t wrapped to look like\nthe Go package big's integer type Int.\n\nThis is a syntactically valid Go program—it can be parsed with the Go\nparser and processed by godoc—but it is not compiled directly by 6g.\nInstead, a separate tool, cgo, processes it to produce three output\nfiles.  The first two, 6g.go and 6c.c, are a Go source file for 6g and\na C source file for 6c; both compile as part of the named package\n(gmp, in this example).  The third, gcc.c, is a C source file for gcc;\nit compiles into a shared object (.so) that is dynamically linked into\nany 6.out that imports the first two files.\n\nThe stanza\n\n\t\/\/ #include <gmp.h>\n\timport \"C\"\n\nis a signal to cgo.  The doc comment on the import of \"C\" provides\nadditional context for the C file.  Here it is just a single #include\nbut it could contain arbitrary C definitions to be imported and used.\n\nCgo recognizes any use of a qualified identifier C.xxx and uses gcc to\nfind the definition of xxx.  If xxx is a type, cgo replaces C.xxx with\na Go translation.  C arithmetic types translate to precisely-sized Go\narithmetic types.  A C struct translates to a Go struct, field by\nfield; unrepresentable fields are replaced with opaque byte arrays.  A\nC union translates into a struct containing the first union member and\nperhaps additional padding.  C arrays become Go arrays.  C pointers\nbecome Go pointers.  C function pointers become Go's uintptr.\nC void pointer's become Go's unsafe.Pointer.\n\nFor example, mpz_t is defined in <gmp.h> as:\n\n\ttypedef unsigned long int mp_limb_t;\n\n\ttypedef struct\n\t{\n\t\tint _mp_alloc;\n\t\tint _mp_size;\n\t\tmp_limb_t *_mp_d;\n\t} __mpz_struct;\n\n\ttypedef __mpz_struct mpz_t[1];\n\nCgo generates:\n\n\ttype _C_int int32\n\ttype _C_mp_limb_t uint64\n\ttype _C___mpz_struct struct {\n\t\t_mp_alloc _C_int;\n\t\t_mp_size _C_int;\n\t\t_mp_d *_C_mp_limb_t;\n\t}\n\ttype _C_mpz_t [1]_C___mpz_struct\n\nand then replaces each occurrence of a type C.xxx with _C_xxx.\n\nIf xxx is data, cgo arranges for C.xxx to refer to the C variable,\nwith the type translated as described above.  To do this, cgo must\nintroduce a Go variable that points at the C variable (the linker can\nbe told to initialize this pointer).  For example, if the gmp library\nprovided\n\n\tmpz_t zero;\n\nthen cgo would rewrite a reference to C.zero by introducing\n\n\tvar _C_zero *C.mpz_t\n\nand then replacing all instances of C.zero with (*_C_zero).\n\nCgo's most interesting translation is for functions.  If xxx is a C\nfunction, then cgo rewrites C.xxx into a new function _C_xxx that\ncalls the C xxx in a standard pthread.  The new function translates\nits arguments, calls xxx, and translates the return value.\n\nTranslation of parameters and the return value follows the type\ntranslation above except that arrays passed as parameters translate\nexplicitly in Go to pointers to arrays, as they do (implicitly) in C.\n\nGarbage collection is the big problem.  It is fine for the Go world to\nhave pointers into the C world and to free those pointers when they\nare no longer needed.  To help, the Go code can define Go objects\nholding the C pointers and use runtime.SetFinalizer on those Go objects.\n\nIt is much more difficult for the C world to have pointers into the Go\nworld, because the Go garbage collector is unaware of the memory\nallocated by C.  The most important consideration is not to\nconstrain future implementations, so the rule is that Go code can\nhand a Go pointer to C code but must separately arrange for\nGo to hang on to a reference to the pointer until C is done with it.\n*\/\npackage gmp\n\n\/*\n#cgo LDFLAGS: -lgmp\n#include <gmp.h>\n#include <stdlib.h>\n\n\/\/ gmp 5.0.0+ changed the type of the 3rd argument to mp_bitcnt_t,\n\/\/ so, to support older versions, we wrap these two functions.\nvoid _mpz_mul_2exp(mpz_ptr a, mpz_ptr b, unsigned long n) {\n\tmpz_mul_2exp(a, b, n);\n}\nvoid _mpz_div_2exp(mpz_ptr a, mpz_ptr b, unsigned long n) {\n\tmpz_div_2exp(a, b, n);\n}\n*\/\nimport \"C\"\n\nimport (\n\t\"os\"\n\t\"unsafe\"\n)\n\n\/*\n * one of a kind\n *\/\n\n\/\/ An Int represents a signed multi-precision integer.\n\/\/ The zero value for an Int represents the value 0.\ntype Int struct {\n\ti    C.mpz_t\n\tinit bool\n}\n\n\/\/ NewInt returns a new Int initialized to x.\nfunc NewInt(x int64) *Int { return new(Int).SetInt64(x) }\n\n\/\/ Int promises that the zero value is a 0, but in gmp\n\/\/ the zero value is a crash.

The most important consideration is not to\nconstrain future implementations, so the rule is that Go code can\nhand a Go pointer to C code but must separately arrange for\nGo to hang on to a reference to the pointer until C is done with it.\n*\/\npackage gmp\n\n\/*\n#cgo LDFLAGS: -lgmp\n#include <gmp.h>\n#include <stdlib.h>\n\n\/\/ gmp 5.0.0+ changed the type of the 3rd argument to mp_bitcnt_t,\n\/\/ so, to support older versions, we wrap these two functions.\nvoid _mpz_mul_2exp(mpz_ptr a, mpz_ptr b, unsigned long n) {\n\tmpz_mul_2exp(a, b, n);\n}\nvoid _mpz_div_2exp(mpz_ptr a, mpz_ptr b, unsigned long n) {\n\tmpz_div_2exp(a, b, n);\n}\n*\/\nimport \"C\"\n\nimport (\n\t\"os\"\n\t\"unsafe\"\n)\n\n\/*\n * one of a kind\n *\/\n\n\/\/ An Int represents a signed multi-precision integer.\n\/\/ The zero value for an Int represents the value 0.\ntype Int struct {\n\ti    C.mpz_t\n\tinit bool\n}\n\n\/\/ NewInt returns a new Int initialized to x.\nfunc NewInt(x int64) *Int { return new(Int).SetInt64(x) }\n\n\/\/ Int promises that the zero value is a 0, but in gmp\n\/\/ the zero value is a crash.

This number can be set to 0 iff\n\t\/\/ allow-zero-initial-scale of config-autoscaler is true.\n\tInitialScaleAnnotationKey = GroupName + \"\/initialScale\"\n\n\t\/\/ MetricAnnotationKey is the annotation to specify what metric the PodAutoscaler\n\t\/\/ should be scaled on. For example,\n\t\/\/   autoscaling.knative.dev\/metric: cpu\n\tMetricAnnotationKey = GroupName + \"\/metric\"\n\t\/\/ Concurrency is the number of requests in-flight at any given time.\n\tConcurrency = \"concurrency\"\n\t\/\/ CPU is the amount of the requested cpu actually being consumed by the Pod.\n\tCPU = \"cpu\"\n\t\/\/ RPS is the requests per second reaching the Pod.\n\tRPS = \"rps\"\n\n\t\/\/ TargetAnnotationKey is the annotation to specify what metric value the\n\t\/\/ PodAutoscaler should attempt to maintain. For example,\n\t\/\/   autoscaling.knative.dev\/metric: cpu\n\t\/\/   autoscaling.knative.dev\/target: \"75\"   # target 75% cpu utilization\n\tTargetAnnotationKey = GroupName + \"\/target\"\n\t\/\/ TargetMin is the minimum allowable target.\n\t\/\/ This can be less than 1 due to the fact that with small container\n\t\/\/ concurrencies and small target utilization values this can get\n\t\/\/ below 1.\n\tTargetMin = 0.01\n\n\t\/\/ ScaleToZeroPodRetentionPeriodKey is the annotation to specify the minimum\n\t\/\/ time duration the last pod will not be scaled down, after autoscaler has\n\t\/\/ made the decision to scale to 0.\n\t\/\/ This is the per-revision setting compliment to the\n\t\/\/ scale-to-zero-pod-retention-period global setting.\n\tScaleToZeroPodRetentionPeriodKey = GroupName + \"\/scaleToZeroPodRetentionPeriod\"\n\n\t\/\/ WindowAnnotationKey is the annotation to specify the time\n\t\/\/ interval over which to calculate the average metric.  Larger\n\t\/\/ values result in more smoothing. For example,\n\t\/\/   autoscaling.knative.dev\/metric: concurrency\n\t\/\/   autoscaling.knative.dev\/window: \"2m\"\n\t\/\/ Only the kpa.autoscaling.knative.dev class autoscaler supports\n\t\/\/ the window annotation.\n\tWindowAnnotationKey = GroupName + \"\/window\"\n\t\/\/ WindowMin is the minimum allowable stable autoscaling\n\t\/\/ window. KPA-class autoscalers calculate the desired replica\n\t\/\/ count every 2 seconds (tick-interval in config-autoscaler) so\n\t\/\/ the closer the window gets to that value, the more likely data\n\t\/\/ points will be missed entirely by the panic window which is\n\t\/\/ smaller than the stable window. Anything less than 6 seconds\n\t\/\/ isn't going to work well.\n\tWindowMin = 6 * time.Second\n\t\/\/ WindowMax is the maximum permitted stable autoscaling window.\n\t\/\/ This keeps the event horizon to a reasonable enough limit.\n\tWindowMax = 1 * time.Hour\n\n\t\/\/ TargetUtilizationPercentageKey is the annotation which specifies the\n\t\/\/ desired target resource utilization for the revision.\n\t\/\/ TargetUtilization is a percentage in the 1 <= TU <= 100 range.\n\t\/\/ This annotation takes precedence over the config map value.\n\tTargetUtilizationPercentageKey = GroupName + \"\/targetUtilizationPercentage\"\n\n\t\/\/ TargetBurstCapacityKey specifies the desired burst capacity for the\n\t\/\/ revision. Possible values are:\n\t\/\/ -1 -- infinite;\n\t\/\/  0 -- no TBC;\n\t\/\/ >0 -- actual TBC.\n\t\/\/ <0 && != -1 -- an error.\n\tTargetBurstCapacityKey = GroupName + \"\/targetBurstCapacity\"\n\n\t\/\/ PanicWindowPercentageAnnotationKey is the annotation to\n\t\/\/ specify the time interval over which to calculate the average\n\t\/\/ metric during a spike. Where a spike is defined as the metric\n\t\/\/ reaching panic level within the panic window (e.g. panic\n\t\/\/ mode). Lower values make panic mode more sensitive. Note:\n\t\/\/ Panic threshold can be overridden with the\n\t\/\/ PanicThresholdPercentageAnnotationKey. For example,\n\t\/\/   autoscaling.knative.dev\/panicWindowPercentage: \"5.0\"\n\t\/\/   autoscaling.knative.dev\/panicThresholdPercentage: \"150.0\"\n\t\/\/ Only the kpa.autoscaling.knative.dev class autoscaler supports\n\t\/\/ the panicWindowPercentage annotation.\n\t\/\/ Panic window is specified as a percentage to maintain the\n\t\/\/ autoscaler's algorithm behavior when only the stable window is\n\t\/\/ specified. The panic window will change along with the stable\n\t\/\/ window at the default percentage.\n\tPanicWindowPercentageAnnotationKey = GroupName + \"\/panicWindowPercentage\"\n\t\/\/ PanicWindowPercentageMin is the minimum allowable panic window\n\t\/\/ percentage. The autoscaler calculates desired replicas every 2\n\t\/\/ seconds (tick-interval in config-autoscaler), so a panic\n\t\/\/ window less than 2 seconds will be missing data points. One\n\t\/\/ percent is a very small ratio and would require a stable\n\t\/\/ window of at least 3.4 minutes. Anything less doesn't make\n\t\/\/ sense.\n\tPanicWindowPercentageMin = 1.0\n\t\/\/ PanicWindowPercentageMax is the maximum allowable panic window\n\t\/\/ percentage. The KPA autoscaler's panic feature allows the\n\t\/\/ autoscaler to be more responsive over a smaller time scale\n\t\/\/ when necessary. So the panic window cannot be larger than the\n\t\/\/ stable window.\n\tPanicWindowPercentageMax = 100.0\n\n\t\/\/ PanicThresholdPercentageAnnotationKey is the annotation to specify\n\t\/\/ the level at what level panic mode will engage when reached within\n\t\/\/ in the panic window. The level is defined as a percentage of\n\t\/\/ the metric target. Lower values make panic mode more\n\t\/\/ sensitive. For example,\n\t\/\/   autoscaling.knative.dev\/panicWindowPercentage: \"5.0\"\n\t\/\/   autoscaling.knative.dev\/panicThresholdPercentage: \"150.0\"\n\t\/\/ Only the kpa.autoscaling.knative.dev class autoscaler supports\n\t\/\/ the panicThresholdPercentage annotation\n\tPanicThresholdPercentageAnnotationKey = GroupName + \"\/panicThresholdPercentage\"\n\t\/\/ PanicThresholdPercentageMin is the minimum allowable panic\n\t\/\/ threshold percentage. The KPA autoscaler's panic feature\n\t\/\/ allows the autoscaler to be more responsive over a smaller\n\t\/\/ time scale when necessary. To prevent flapping, during panic\n\t\/\/ mode the autoscaler never decreases the number of replicas. If\n\t\/\/ the panic threshold was as small as the stable target, the\n\t\/\/ autoscaler would always be panicking and the autoscaler would\n\t\/\/ never scale down. One hundred and ten percent is about the\n\t\/\/ smallest useful value.\n\tPanicThresholdPercentageMin = 110.0\n\n\t\/\/ PanicThresholdPercentageMax is the counterpart to the PanicThresholdPercentageMin\n\t\/\/ but bounding from above.\n\tPanicThresholdPercentageMax = 1000.0\n\n\t\/\/ KPALabelKey is the label key attached to a K8s Service to hint to the KPA\n\t\/\/ which services\/endpoints should trigger reconciles.\n\tKPALabelKey = GroupName + \"\/kpa\"\n)\n<|endoftext|>"}

It assumes\n\/\/ that the incoming bytes represent UTF-8 encoded text consisting of\n\/\/ lines of tab-terminated \"cells\". Cells in adjacent lines constitute\n\/\/ a column. Writer rewrites the incoming text such that all cells in\n\/\/ a column have the same width; thus it effectively aligns cells. It\n\/\/ does this by adding padding where necessary. All characters (ASCII\n\/\/ or not) are assumed to be of the same width - this may not be true\n\/\/ for arbitrary UTF-8 characters visualized on the screen.\n\/\/\n\/\/ Note that any text at the end of a line that is not tab-terminated\n\/\/ is not a cell and does not enforce alignment of cells in adjacent\n\/\/ rows. To make it a cell it needs to be tab-terminated.

Cells in adjacent lines\n\/\/ constitute a column. The Writer inserts padding as needed\n\/\/ to make all cells in a column have the same width, effectively\n\/\/ aligning the columns. Note that cells are tab-terminated,\n\/\/ not tab-separated: trailing non-tab text at the end of a line\n\/\/ is not part of any cell.\n\/\/\n\/\/ The Writer assumes that all characters have the same width;\n\/\/ this may not be true in some fonts, especially with certain\n\/\/ UTF-8 characters.\n\/\/\n\/\/ The Writer must buffer input internally, because proper spacing\n\/\/ of one line may depend on the cells in future lines. Clients must\n\/\/ call Flush when done calling Write.\n\/\/\ntype Writer struct {\n\t\/\/ configuration\n\toutput io.Write;\n\tcellwidth int;\n\tpadding int;\n\tpadbytes [8]byte;\n\talign_left bool;\n\tfilter_html bool;\n\n\t\/\/ current state\n\thtml_char byte;  \/\/ terminating char of html tag\/entity, or 0 ('>', ';', or 0)\n\tbuf byteArray;  \/\/ collected text w\/o tabs and newlines\n\tsize int;  \/\/ size of incomplete cell in bytes\n\twidth int;  \/\/ width of incomplete cell in runes up to buf[pos] w\/o ignored sections\n\tpos int;  \/\/ buffer position up to which width of incomplete cell has been computed\n\tlines_size vector.Vector;  \/\/ list of lines; each line is a list of cell sizes in bytes\n\tlines_width vector.Vector;  \/\/ list of lines; each line is a list of cell widths in runes\n\twidths vector.IntVector;  \/\/ list of column widths in runes - re-used during formatting\n}\n\n\n\/\/ Internal representation (current state):\n\/\/\n\/\/ - all text written is appended to buf; tabs and newlines are stripped away\n\/\/ - at any given time there is a (possibly empty) incomplete cell at the end\n\/\/   (the cell starts after a tab or newline)\n\/\/ - size is the number of bytes belonging to the cell so far\n\/\/ - width is text width in runes of that cell from the start of the cell to\n\/\/   position pos; html tags and entities are excluded from this width if html\n\/\/   filtering is enabled\n\/\/ - the sizes and widths of processed text are kept in the lines_size and\n\/\/   lines_width arrays, which contain an array of sizes or widths for each line\n\/\/ - the widths array is a temporary array with current widths used during\n\/\/   formatting; it is kept in Writer because it's re-used\n\/\/\n\/\/                    |<---------- size ---------->|\n\/\/                    |                            |\n\/\/                    |<- width ->|<- ignored ->|  |\n\/\/                    |           |             |  |\n\/\/ [---processed---tab------------<tag>...<\/tag>...]\n\/\/ ^                  ^                         ^\n\/\/ |                  |                         |\n\/\/ buf                start of incomplete cell  pos\n\n\nfunc (b *Writer) addLine() {\n\tb.lines_size.Push(vector.NewIntVector(0));\n\tb.lines_width.Push(vector.NewIntVector(0));\n}\n\n\n\/\/ A Writer must be initialized with a call to Init.

{"text":"<commit_before>\/*\ngoqu is a library built with the following goals:\n\n    1. Make the generation of SQL easy and enjoyable\n    2. Provide a DSL that accounts for the common SQL expressions, NOT every nuance for each database.\n    3. Allow users to use SQL when desired\n    4. Provide a simple query API for scanning rows\n    5. Allow the user to use the native sql.Db methods when desired\n\nFeatures\n\ngoqu was comes with many features but here are a few of the more notable ones\n\n    1. Query Builder\n    2. Parameter interpolation (e.g SELECT * FROM \"items\" WHERE \"id\" = ? -> SELECT * FROM \"items\" WHERE \"id\" = 1)\n    3. Built from the ground up with adapters in mind\n    4. Insert, Multi Insert, Update, and Delete support\n    5. Scanning of rows to struct[s] or primitive value[s]\n\nWhile goqu may support the scanning of rows into structs it is not intended to be used as an ORM if you are looking for common ORM features like associations,\nor hooks I would recommend looking at some of the great ORM libraries such as https:\/\/github.com\/jinzhu\/gorm\n\nBasics\n\nIn order to start using goqu with your database you need to load an adapter.

List returns all stories matching the filter in case the filter is specified.\n\/\/\n\/\/ List actually sends 2 HTTP requests - one to get the total number of stories,\n\/\/ another to retrieve the stories using the right pagination setup.

It's in these\n\t\/\/ functions that we actually bind the Go kit server\/handler structs to the\n\t\/\/ concrete transports and run them.\n\t\/\/\n\t\/\/ Putting each component into its own block is mostly for aesthetics: it\n\t\/\/ clearly demarcates the scope in which each listener\/socket may be used.\n\tvar g group.Group\n\t{\n\t\t\/\/ The debug listener mounts the http.DefaultServeMux, and serves up\n\t\t\/\/ stuff like the Prometheus metrics route, the Go debug and profiling\n\t\t\/\/ routes, and so on.\n\t\tdebugListener, err := net.Listen(\"tcp\", *debugAddr)\n\t\tif err != nil {\n\t\t\tlogger.Log(\"transport\", \"debug\/HTTP\", \"during\", \"Listen\", \"err\", err)\n\t\t\tos.Exit(1)\n\t\t}\n\t\tg.Add(func() error {\n\t\t\tlogger.Log(\"transport\", \"debug\/HTTP\", \"addr\", *debugAddr)\n\t\t\treturn http.Serve(debugListener, http.DefaultServeMux)\n\t\t}, func(error) {\n\t\t\tdebugListener.Close()\n\t\t})\n\t}\n\t{\n\t\t\/\/ The HTTP listener mounts the Go kit HTTP handler we created.\n\t\thttpListener, err := net.Listen(\"tcp\", *httpAddr)\n\t\tif err != nil {\n\t\t\tlogger.Log(\"transport\", \"HTTP\", \"during\", \"Listen\", \"err\", err)\n\t\t\tos.Exit(1)\n\t\t}\n\t\tg.Add(func() error {\n\t\t\tlogger.Log(\"transport\", \"HTTP\", \"addr\", *httpAddr)\n\t\t\treturn http.Serve(httpListener, httpHandler)\n\t\t}, func(error) {\n\t\t\thttpListener.Close()\n\t\t})\n\t}\n\t{\n\t\t\/\/ The gRPC listener mounts the Go kit gRPC server we created.\n\t\tgrpcListener, err := net.Listen(\"tcp\", *grpcAddr)\n\t\tif err != nil {\n\t\t\tlogger.Log(\"transport\", \"gRPC\", \"during\", \"Listen\", \"err\", err)\n\t\t\tos.Exit(1)\n\t\t}\n\t\tg.Add(func() error {\n\t\t\tlogger.Log(\"transport\", \"gRPC\", \"addr\", *grpcAddr)\n\t\t\tbaseServer := grpc.NewServer()\n\t\t\taddpb.RegisterAddServer(baseServer, grpcServer)\n\t\t\treturn baseServer.Serve(grpcListener)\n\t\t}, func(error) {\n\t\t\tgrpcListener.Close()\n\t\t})\n\t}\n\t{\n\t\t\/\/ The Thrift socket mounts the Go kit Thrift server we created earlier.\n\t\t\/\/ There's a lot of boilerplate involved here, related to configuring\n\t\t\/\/ the protocol and transport; blame Thrift.\n\t\tthriftSocket, err := thrift.NewTServerSocket(*thriftAddr)\n\t\tif err != nil {\n\t\t\tlogger.Log(\"transport\", \"Thrift\", \"during\", \"Listen\", \"err\", err)\n\t\t\tos.Exit(1)\n\t\t}\n\t\tg.Add(func() error {\n\t\t\tlogger.Log(\"transport\", \"Thrift\", \"addr\", *thriftAddr)\n\t\t\tvar protocolFactory thrift.TProtocolFactory\n\t\t\tswitch *thriftProtocol {\n\t\t\tcase \"binary\":\n\t\t\t\tprotocolFactory = thrift.NewTBinaryProtocolFactoryDefault()\n\t\t\tcase \"compact\":\n\t\t\t\tprotocolFactory = thrift.NewTCompactProtocolFactory()\n\t\t\tcase \"json\":\n\t\t\t\tprotocolFactory = thrift.NewTJSONProtocolFactory()\n\t\t\tcase \"simplejson\":\n\t\t\t\tprotocolFactory = thrift.NewTSimpleJSONProtocolFactory()\n\t\t\tdefault:\n\t\t\t\treturn fmt.Errorf(\"invalid Thrift protocol %q\", *thriftProtocol)\n\t\t\t}\n\t\t\tvar transportFactory thrift.TTransportFactory\n\t\t\tif *thriftBuffer > 0 {\n\t\t\t\ttransportFactory = thrift.NewTBufferedTransportFactory(*thriftBuffer)\n\t\t\t} else {\n\t\t\t\ttransportFactory = thrift.NewTTransportFactory()\n\t\t\t}\n\t\t\tif *thriftFramed {\n\t\t\t\ttransportFactory = thrift.NewTFramedTransportFactory(transportFactory)\n\t\t\t}\n\t\t\treturn thrift.NewTSimpleServer4(\n\t\t\t\taddthrift.NewAddServiceProcessor(thriftServer),\n\t\t\t\tthriftSocket,\n\t\t\t\ttransportFactory,\n\t\t\t\tprotocolFactory,\n\t\t\t).Serve()\n\t\t}, func(error) {\n\t\t\tthriftSocket.Close()\n\t\t})\n\t}\n\t{\n\t\t\/\/ This function just sits and waits for ctrl-C.\n\t\tcancelInterrupt := make(chan struct{})\n\t\tg.Add(func() error {\n\t\t\tc := make(chan os.Signal, 1)\n\t\t\tsignal.Notify(c, syscall.SIGINT, syscall.SIGTERM)\n\t\t\tselect {\n\t\t\tcase sig := <-c:\n\t\t\t\treturn fmt.Errorf(\"received signal %s\", sig)\n\t\t\tcase <-cancelInterrupt:\n\t\t\t\treturn nil\n\t\t\t}\n\t\t}, func(error) {\n\t\t\tclose(cancelInterrupt)\n\t\t})\n\t}\n\tlogger.Log(\"exit\", g.Run())\n}\n\nfunc usageFor(fs *flag.FlagSet, short string) func() {\n\treturn func() {\n\t\tfmt.Fprintf(os.Stderr, \"USAGE\\n\")\n\t\tfmt.Fprintf(os.Stderr, \"  %s\\n\", short)\n\t\tfmt.Fprintf(os.Stderr, \"\\n\")\n\t\tfmt.Fprintf(os.Stderr, \"FLAGS\\n\")\n\t\tw := tabwriter.NewWriter(os.Stderr, 0, 2, 2, ' ', 0)\n\t\tfs.VisitAll(func(f *flag.Flag) {\n\t\t\tfmt.Fprintf(w, \"\\t-%s %s\\t%s\\n\", f.Name, f.DefValue, f.Usage)\n\t\t})\n\t\tw.Flush()\n\t\tfmt.Fprintf(os.Stderr, \"\\n\")\n\t}\n}\n<|endoftext|>"}

This behaviour can be\n\/\/ modified using a '&' at the end of the line which will cause the command to\n\/\/ run in the background.  Additionally, flags and options can be specified\n\/\/ after a '#' character to control what image is used or to apply other action\n\/\/ flags.\n\/\/\n\/\/ Files from GCS can be specified as inputs to the script using the --inputs\n\/\/ flag.  These files will be copied onto the VM.  The names of the localized\n\/\/ files are exposed via the environment variables $INPUT0 to $INPUTN.  Note\n\/\/ that the input files are placed on a read-only disk.\n\/\/\n\/\/ Similarly, destinations in GCS may be specified with the --outputs flag.\n\/\/ Each output file will be exposed by via the environment variables $OUTPUT0\n\/\/ to $OUTPUTN.\n\/\/\n\/\/ As a convenience, the tool will automatically use the google\/cloud-sdk image\n\/\/ whenever the command line starts with gsutil or gcloud, and will\n\/\/ automatically include the cloud-platform API scope whenever the cloud-sdk\n\/\/ container is used.\n\/\/\n\/\/ Any 'export' commands are interpreted prior to execution of the pipeline.\n\/\/ The specified value is injected into the environment for all subsequent\n\/\/ commands.\n\/\/\n\/\/ Variable references of the form ${VARIABLE} or $VARIABLE are replaced using\n\/\/ values from the host environment (unless the value has been overwritten by a\n\/\/ previous export command).\n\/\/\n\/\/ If any command references '\/tmp' the attached persistent disk is mounted\n\/\/ there, read-write.\n\/\/\n\/\/ If the --output flag is specified, an action is appended that copies the\n\/\/ combined pipeline output to the specified GCS path.\n\/\/\n\/\/ The --dry-run flag can be used to see what pipeline would be produced\n\/\/ without executing it.\n\/\/\n\/\/ Example 1: Simple 'hello world' script\n\/\/\n\/\/    echo \"Hello World!\"\n\/\/\n\/\/ Example 2: Background action\n\/\/\n\/\/    while true; do echo \"Hello background world!\"; sleep 1; done &\n\/\/    sleep 5\n\/\/    echo \"Hello foreground world!\"\n\/\/\n\/\/ Example 3: Indexing a BAM\n\/\/\n\/\/

governing permissions and\n\/\/ limitations under the License.\n\n\/\/ Package run provides a sub tool for running pipelines.\npackage run\n\n\/\/ This tool takes as an input a script file composed of a series of command\n\/\/ lines to execute.\n\/\/\n\/\/ By default, each command line is executed using the 'bash' container and\n\/\/ must succeed before the next command is executed.  This behaviour can be\n\/\/ modified using a '&' at the end of the line which will cause the command to\n\/\/ run in the background.  Additionally, flags and options can be specified\n\/\/ after a '#' character to control what image is used or to apply other action\n\/\/ flags.\n\/\/\n\/\/ Files from GCS can be specified as inputs to the script using the --inputs\n\/\/ flag.  These files will be copied onto the VM.  The names of the localized\n\/\/ files are exposed via the environment variables $INPUT0 to $INPUTN.  Note\n\/\/ that the input files are placed on a read-only disk.\n\/\/\n\/\/ Similarly, destinations in GCS may be specified with the --outputs flag.\n\/\/ Each output file will be exposed by via the environment variables $OUTPUT0\n\/\/ to $OUTPUTN.\n\/\/\n\/\/ As a convenience, the tool will automatically use the google\/cloud-sdk image\n\/\/ whenever the command line starts with gsutil or gcloud, and will\n\/\/ automatically include the cloud-platform API scope whenever the cloud-sdk\n\/\/ container is used.\n\/\/\n\/\/ Any 'export' commands are interpreted prior to execution of the pipeline.\n\/\/ The specified value is injected into the environment for all subsequent\n\/\/ commands.\n\/\/\n\/\/ Variable references of the form ${VARIABLE} or $VARIABLE are replaced using\n\/\/ values from the host environment (unless the value has been overwritten by a\n\/\/ previous export command).\n\/\/\n\/\/ If any command references '\/tmp' the attached persistent disk is mounted\n\/\/ there, read-write.\n\/\/\n\/\/ If the --output flag is specified, an action is appended that copies the\n\/\/ combined pipeline output to the specified GCS path.\n\/\/\n\/\/ The --dry-run flag can be used to see what pipeline would be produced\n\/\/ without executing it.\n\/\/\n\/\/ Example 1: Simple 'hello world' script\n\/\/\n\/\/    echo \"Hello World!\"\n\/\/\n\/\/ Example 2: Background action\n\/\/\n\/\/    while true; do echo \"Hello background world!\"; sleep 1; done &\n\/\/    sleep 5\n\/\/    echo \"Hello foreground world!\"\n\/\/\n\/\/ Example 3: Indexing a BAM\n\/\/\n\/\/    export BAM=NA12892_S1.bam\n\/\/    export BAI=${BAM}.bai\n\/\/    gsutil cp gs:\/\/my-bucket\/${BAM} \/tmp\n\/\/    index \/tmp\/${BAM} \/tmp\/${BAI} # image=gcr.io\/genomics-tools\/samtools\n\/\/    gsutil cp \/tmp\/${BAI} gs:\/\/my-bucket\/\n\/\/\n\/\/ Example 4: SHA1 sum a file (using the --inputs and --outputs flags).\n\/\/\n\/\/    sha1sum ${INPUT0} > ${OUTPUT0}\n\/\/\nimport

Use plain **\\*ptr** instead.\n\n\tVisit [the Go home page](https:\/\/golang.org\/).\n\nLegacy Present Syntax\n\nCompared to Markdown,\nin legacy present\nslides\/sections use \"*\" instead of \"##\",\nwhole-line comments begin with \"#\" instead of \"\/\/\",\nbullet lists can only contain single (possibly wrapped) text lines,\nand the font styling and link syntaxes are subtly different.\n\nExample:\n\n\tTitle of Talk\n\n\tMy Name\n\t1 Jan 2013\n\tme@example.com\n\n\t* Title of Slide or Section (must begin with *)\n\n\tSome Text\n\n\t** Subsection\n\n\t- bullets\n\t- more bullets\n\t- a bullet continued\n\t  on the next line (indented at least one space)\n\n\t*** Sub-subsection\n\n\tSome More text\n\n\t  Preformatted text (code block)\n\t  is indented (however you like)\n\n\tFurther Text, including command invocations.\n\n\t* Section 2: Example formatting\n\n\tFormatting:\n\n\t_italic_\n\t*bold*\n\t`program`\n\tMarkup—_especially_italic_text_—can easily be overused.\n\t_Why_use_scoped__ptr_? Use plain ***ptr* instead.\n\n\tVisit [[https:\/\/golang.org][the Go home page]].\n\nWithin the input for plain text or lists, text bracketed by font\nmarkers will be presented in italic, bold, or program font.\nMarker characters are _ (italic), * (bold) and ` (program font).\nAn opening marker must be preceded by a space or punctuation\ncharacter or else be at start of a line; similarly, a closing\nmarker must be followed by a space or punctuation character or\nelse be at the end of a line. Unmatched markers appear as plain text.\nThere must be no spaces between markers. Within marked text,\na single marker character becomes a space and a doubled single\nmarker quotes the marker character.\n\nLinks can be included in any text with the form [[url][label]], or\n[[url]] to use the URL itself as the label.\n\nCommand Invocations\n\nA number of special commands are available through invocations\nin the input text. Each such invocation contains a period as the\nfirst character on the line, followed immediately by the name of\nthe function, followed by any arguments. A typical invocation might\nbe\n\n\t.play demo.go \/^func show\/,\/^}\/\n\n(except that the \".play\" must be at the beginning of the line and\nnot be indented as in this comment.)\n\nHere follows a description of the functions:\n\ncode:\n\nInjects program source into the output by extracting code from files\nand injecting them as HTML-escaped <pre> blocks.  The argument is\na file name followed by an optional address that specifies what\nsection of the file to display. The address syntax is similar in\nits simplest form to that of ed, but comes from sam and is more\ngeneral. See\n\thttps:\/\/plan9.io\/sys\/doc\/sam\/sam.html Table II\nfor full details. The displayed block is always rounded out to a\nfull line at both ends.\n\nIf no pattern is present, the entire file is displayed.\n\nAny line in the program that ends with the four characters\n\tOMIT\nis deleted from the source before inclusion, making it easy\nto write things like\n\t.code test.go \/START OMIT\/,\/END OMIT\/\nto find snippets like this\n\ttedious_code = boring_function()\n\t\/\/ START OMIT\n\tinteresting_code = fascinating_function()\n\t\/\/ END OMIT\nand see only this:\n\tinteresting_code = fascinating_function()\n\nAlso, inside the displayed text a line that ends\n\t\/\/ HL\nwill be highlighted in the display. A highlighting mark may have a\nsuffix word, such as\n\t\/\/ HLxxx\nSuch highlights are enabled only if the code invocation ends with\n\"HL\" followed by the word:\n\t.code test.go \/^type Foo\/,\/^}\/ HLxxx\n\nThe .code function may take one or more flags immediately preceding\nthe filename. This command shows test.go in an editable text area:\n\t.code -edit test.go\nThis command shows test.go with line numbers:\n\t.code -numbers test.go\n\nplay:\n\nThe function \"play\" is the same as \"code\" but puts a button\non the displayed source so the program can be run from the browser.\nAlthough only the selected text is shown, all the source is included\nin the HTML output so it can be presented to the compiler.\n\nlink:\n\nCreate a hyperlink.

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 present implements parsing and rendering of present files,\nwhich can be slide presentations as in golang.org\/x\/tools\/cmd\/present\nor articles as in golang.org\/x\/blog (the Go blog).\n\nFile Format\n\nPresent files begin with a header giving the title of the document\nand other metadata, which looks like:\n\n\t# Title of document\n\tSubtitle of document\n\t15:04 2 Jan 2006\n\tTags: foo, bar, baz\n\tSummary: This is a great document you want to read.\n\tOldURL: former-path-for-this-doc\n\nThe \"# \" prefix before the title indicates that this is\na Markdown-enabled present file: it uses\nMarkdown for text markup in the body of the file.\nIf the \"# \" prefix is missing, the file uses\nlegacy present markup, described below.\n\nThe date line may be written without a time:\n\t2 Jan 2006\nIn this case, the time will be interpreted as 10am UTC on that date.\n\nThe tags line is a comma-separated list of tags that may be used to categorize\nthe document.\n\nThe summary line gives a short summary used in blog feeds.\n\nThe old URL line, which may be repeated, gives an older (perhaps relative) URL\nfor this document.\nA server might use these to generate appropriate redirects.\n\nOnly the title is required;\nthe subtitle, date, tags, summary, and old URL lines are optional.\nIn Markdown-enabled present, the summary defaults to being empty.\nIn legacy present, the summary defaults to the first paragraph of text.\n\nAfter the header come zero or more author blocks, like this:\n\n\tAuthor Name\n\tJob title, Company\n\tjoe@example.com\n\thttps:\/\/url\/\n\t@twitter_name\n\nThe first line of the author block is conventionally the author name.\nOtherwise, the author section may contain a mixture of text, twitter names, and links.\nFor slide presentations, only the plain text lines will be displayed on the\nfirst slide.\n\nIf multiple author blocks are listed, each new block must be preceded\nby its own blank line.\n\nAfter the author blocks come the presentation slides or article sections,\nwhich can in turn have subsections.\nIn Markdown-enabled present files, each slide or section begins with a \"##\" header line,\nsubsections begin with a \"###\" header line, and so on.\nIn legacy present files, each slide or section begins with a \"*\" header line,\nsubsections begin with a \"**\" header line, and so on.\n\nIn addition to the marked-up text in a section (or subsection),\na present file can contain present command invocations, each of which begins\nwith a dot, as in:\n\n\t.code x.go \/^func main\/,\/^}\/\n\t.play y.go\n\t.image image.jpg\n\t.background image.jpg\n\t.iframe https:\/\/foo\n\t.link https:\/\/foo label\n\t.html file.html\n\t.caption _Gopher_ by [[https:\/\/instagram.com\/reneefrench][Renee French]]\n\nOther than the commands, the text in a section is interpreted\neither as Markdown or as legacy present markup.\n\nMarkdown Syntax\n\nMarkdown typically means the generic name for a family of similar markup languages.\nThe specific variant used in present is CommonMark.\nSee https:\/\/commonmark.org\/help\/tutorial\/ for a quick tutorial.\n\nIn Markdown-enabled present,\nsection headings can end in {#name} to set the HTML anchor ID for the heading to \"name\".\n\nLines beginning with \"\/\/\" (outside of code blocks, of course)\nare treated as present comments and have no effect.\n\nLines beginning with \": \" are treated as speaker notes, described below.\n\nExample:\n\n\t# Title of Talk\n\n\tMy Name\n\t9 Mar 2020\n\tme@example.com\n\n\t## Title of Slide or Section (must begin with ##)\n\n\tSome Text\n\n\t### Subsection {#anchor}\n\n\t- bullets\n\t- more bullets\n\t- a bullet continued\n\t  on the next line\n\n\t#### Sub-subsection\n\n\tSome More text\n\n\t\tPreformatted text (code block)\n\t\tis indented (by one tab, or four spaces)\n\n\tFurther Text, including command invocations.\n\n\t## Section 2: Example formatting {#fmt}\n\n\tFormatting:\n\n\t_italic_\n\t\/\/ A comment that is completely ignored.\n\t: Speaker notes.\n\t**bold**\n\t`program`\n\tMarkup—_especially italic text_—can easily be overused.\n\t_Why use scoped\\_ptr_? Use plain **\\*ptr** instead.\n\n\tVisit [the Go home page](https:\/\/golang.org\/).\n\nLegacy Present Syntax\n\nCompared to Markdown,\nin legacy present\nslides\/sections use \"*\" instead of \"##\",\nwhole-line comments begin with \"#\" instead of \"\/\/\",\nbullet lists can only contain single (possibly wrapped) text lines,\nand the font styling and link syntaxes are subtly different.\n\nExample:\n\n\tTitle of Talk\n\n\tMy Name\n\t1 Jan 2013\n\tme@example.com\n\n\t* Title of Slide or Section (must begin with *)\n\n\tSome Text\n\n\t** Subsection\n\n\t- bullets\n\t- more bullets\n\t- a bullet continued\n\t  on the next line (indented at least one space)\n\n\t*** Sub-subsection\n\n\tSome More text\n\n\t  Preformatted text (code block)\n\t  is indented (however you like)\n\n\tFurther Text, including command invocations.\n\n\t* Section 2: Example formatting\n\n\tFormatting:\n\n\t_italic_\n\t*bold*\n\t`program`\n\tMarkup—_especially_italic_text_—can easily be overused.\n\t_Why_use_scoped__ptr_? Use plain ***ptr* instead.\n\n\tVisit [[https:\/\/golang.org][the Go home page]].\n\nWithin the input for plain text or lists, text bracketed by font\nmarkers will be presented in italic, bold, or program font.\nMarker characters are _ (italic), * (bold) and ` (program font).\nAn opening marker must be preceded by a space or punctuation\ncharacter or else be at start of a line; similarly, a closing\nmarker must be followed by a space or punctuation character or\nelse be at the end of a line. Unmatched markers appear as plain text.\nThere must be no spaces between markers. Within marked text,\na single marker character becomes a space and a doubled single\nmarker quotes the marker character.\n\nLinks can be included in any text with the form [[url][label]], or\n[[url]] to use the URL itself as the label.\n\nCommand Invocations\n\nA number of special commands are available through invocations\nin the input text. Each such invocation contains a period as the\nfirst character on the line, followed immediately by the name of\nthe function, followed by any arguments. A typical invocation might\nbe\n\n\t.play demo.go \/^func show\/,\/^}\/\n\n(except that the \".play\" must be at the beginning of the line and\nnot be indented as in this comment.)\n\nHere follows a description of the functions:\n\ncode:\n\nInjects program source into the output by extracting code from files\nand injecting them as HTML-escaped <pre> blocks.  The argument is\na file name followed by an optional address that specifies what\nsection of the file to display. The address syntax is similar in\nits simplest form to that of ed, but comes from sam and is more\ngeneral. See\n\thttps:\/\/plan9.io\/sys\/doc\/sam\/sam.html Table II\nfor full details. The displayed block is always rounded out to a\nfull line at both ends.\n\nIf no pattern is present, the entire file is displayed.\n\nAny line in the program that ends with the four characters\n\tOMIT\nis deleted from the source before inclusion, making it easy\nto write things like\n\t.code test.go \/START OMIT\/,\/END OMIT\/\nto find snippets like this\n\ttedious_code = boring_function()\n\t\/\/ START OMIT\n\tinteresting_code = fascinating_function()\n\t\/\/ END OMIT\nand see only this:\n\tinteresting_code = fascinating_function()\n\nAlso, inside the displayed text a line that ends\n\t\/\/ HL\nwill be highlighted in the display. A highlighting mark may have a\nsuffix word, such as\n\t\/\/ HLxxx\nSuch highlights are enabled only if the code invocation ends with\n\"HL\" followed by the word:\n\t.code test.go \/^type Foo\/,\/^}\/ HLxxx\n\nThe .code function may take one or more flags immediately preceding\nthe filename. This command shows test.go in an editable text area:\n\t.code -edit test.go\nThis command shows test.go with line numbers:\n\t.code -numbers test.go\n\nplay:\n\nThe function \"play\" is the same as \"code\" but puts a button\non the displayed source so the program can be run from the browser.\nAlthough only the selected text is shown, all the source is included\nin the HTML output so it can be presented to the compiler.\n\nlink:\n\nCreate a hyperlink.

This is the GNU\nmultiprecision library gmp's integer type mpz_t wrapped to look like\nthe Go package big's integer type Int.\n\nThis is a syntactically valid Go program—it can be parsed with the Go\nparser and processed by godoc—but it is not compiled directly by 6g.\nInstead, a separate tool, cgo, processes it to produce three output\nfiles.  The first two, 6g.go and 6c.c, are a Go source file for 6g and\na C source file for 6c; both compile as part of the named package\n(gmp, in this example).  The third, gcc.c, is a C source file for gcc;\nit compiles into a shared object (.so) that is dynamically linked into\nany 6.out that imports the first two files.\n\nThe stanza\n\n\t\/\/ #include <gmp.h>\n\timport \"C\"\n\nis a signal to cgo.  The doc comment on the import of \"C\" provides\nadditional context for the C file.  Here it is just a single #include\nbut it could contain arbitrary C definitions to be imported and used.\n\nCgo recognizes any use of a qualified identifier C.xxx and uses gcc to\nfind the definition of xxx.  If xxx is a type, cgo replaces C.xxx with\na Go translation.  C arithmetic types translate to precisely-sized Go\narithmetic types.  A C struct translates to a Go struct, field by\nfield; unrepresentable fields are replaced with opaque byte arrays.  A\nC union translates into a struct containing the first union member and\nperhaps additional padding.  C arrays become Go arrays.  C pointers\nbecome Go pointers.  C function pointers become Go's uintptr.\nC void pointer's become Go's unsafe.Pointer.\n\nFor example, mpz_t is defined in <gmp.h> as:\n\n\ttypedef unsigned long int mp_limb_t;\n\n\ttypedef struct\n\t{\n\t\tint _mp_alloc;\n\t\tint _mp_size;\n\t\tmp_limb_t *_mp_d;\n\t} __mpz_struct;\n\n\ttypedef __mpz_struct mpz_t[1];\n\nCgo generates:\n\n\ttype _C_int int32\n\ttype _C_mp_limb_t uint64\n\ttype _C___mpz_struct struct {\n\t\t_mp_alloc _C_int;\n\t\t_mp_size _C_int;\n\t\t_mp_d *_C_mp_limb_t;\n\t}\n\ttype _C_mpz_t [1]_C___mpz_struct\n\nand then replaces each occurrence of a type C.xxx with _C_xxx.\n\nIf xxx is data, cgo arranges for C.xxx to refer to the C variable,\nwith the type translated as described above.  To do this, cgo must\nintroduce a Go variable that points at the C variable (the linker can\nbe told to initialize this pointer).  For example, if the gmp library\nprovided\n\n\tmpz_t zero;\n\nthen cgo would rewrite a reference to C.zero by introducing\n\n\tvar _C_zero *C.mpz_t\n\nand then replacing all instances of C.zero with (*_C_zero).\n\nCgo's most interesting translation is for functions.  If xxx is a C\nfunction, then cgo rewrites C.xxx into a new function _C_xxx that\ncalls the C xxx in a standard pthread.  The new function translates\nits arguments, calls xxx, and translates the return value.\n\nTranslation of parameters and the return value follows the type\ntranslation above except that arrays passed as parameters translate\nexplicitly in Go to pointers to arrays, as they do (implicitly) in C.\n\nGarbage collection is the big problem.  It is fine for the Go world to\nhave pointers into the C world and to free those pointers when they\nare no longer needed.  To help, the garbage collector calls an\nobject's destroy() method prior to collecting it.  C pointers can be\nwrapped by Go objects with appropriate destroy methods.\n\nIt is much more difficult for the C world to have pointers into the Go\nworld, because the Go garbage collector is unaware of the memory\nallocated by C.  The most important consideration is not to\nconstrain future implementations, so the rule is that Go code can\nhand a Go pointer to C code but must separately arrange for\nGo to hang on to a reference to the pointer until C is done with it.\n*\/\npackage gmp\n\n\/\/ #include <gmp.h>\n\/\/ #include <stdlib.h>\nimport \"C\"\n\nimport (\n\t\"os\"\n\t\"unsafe\"\n)\n\n\/*\n * one of a kind\n *\/\n\n\/\/ An Int represents a signed multi-precision integer.\n\/\/ The zero value for an Int represents the value 0.\ntype Int struct {\n\ti    C.mpz_t\n\tinit bool\n}\n\n\/\/ NewInt returns a new Int initialized to x.\nfunc NewInt(x int64) *Int { return new(Int).SetInt64(x) }\n\n\/\/ Int promises that the zero value is a 0, but in gmp\n\/\/ the zero value is a crash.

{"text":"<commit_before>\/\/ Package streams provides robust event streams from Reddit.\n\/\/\n\/\/ This package is not abstract. If you are looking for a simpler, high level\n\/\/ interface, see graw.\n\/\/\n\/\/ The streams provided by this package will not be deterred like naive\n\/\/ implementations by a post getting caught in the spam filter, removed by mods,\n\/\/ the author being shadowbanned, or an author deleting their post. These\n\/\/ streams are in it to win it.\n\/\/\n\/\/ All of the streams provisioned by this package depend on an api handle from\n\/\/ the reddit package, and two control channels: one kill signal and one error\n\/\/ feed.\n\/\/\n\/\/ The kill channel can be shared by multiple streams as long as you signal kill\n\/\/ by close()ing the channel. Sending data over it will kill an arbitrary one of\n\/\/ the streams sharing the channel but not all of them.\n\/\/\n\/\/ The error channel will return issues which may be intermittent. They are not\n\/\/ wrapped, so you can check them against the definitions in the reddit package\n\/\/ and choose to wait when Reddit is busy or the connection faults, instead of\n\/\/ failing.\n\/\/\n\/\/ If there is a problem setting up the stream, such as the endpoint being\n\/\/ invalid, that will be caught in the initial construction of the stream; you\n\/\/ don't need to worry about that on the error channel.\n\/\/\n\/\/ These streams will consume \"intervals\" of the Reddit handle given to them.\n\/\/ Since the reddit handlers are rate limited and do not allow bursts, there is\n\/\/ essentially a schedule on which they execute requests, and the executions\n\/\/ will be divided roughly evenly between the goroutines sharing the handle.\n\/\/ E.g. if you create two user streams which depend on a handle with a rate\n\/\/ limit of 5 seconds, each of them will be unblocked once every 10 seconds\n\/\/ (ish), since they each consume one interval, and the interval is 5 seconds.\npackage streams\n\nimport (\n\t\"strings\"\n\n\t\"github.com\/turnage\/graw\/reddit\"\n\n\t\"github.com\/turnage\/graw\/streams\/internal\/monitor\"\n\t\"github.com\/turnage\/graw\/streams\/internal\/rsort\"\n)\n\n\/\/ Subreddits returns a stream of new posts from the requested subreddits.

If you are looking for a simpler, high level\n\/\/ interface, see graw.\n\/\/\n\/\/ The streams provided by this package will not be deterred like naive\n\/\/ implementations by a post getting caught in the spam filter, removed by mods,\n\/\/ the author being shadowbanned, or an author deleting their post. These\n\/\/ streams are in it to win it.\n\/\/\n\/\/ All of the streams provisioned by this package depend on an api handle from\n\/\/ the reddit package, and two control channels: one kill signal and one error\n\/\/ feed.\n\/\/\n\/\/ The kill channel can be shared by multiple streams as long as you signal kill\n\/\/ by close()ing the channel. Sending data over it will kill an arbitrary one of\n\/\/ the streams sharing the channel but not all of them.\n\/\/\n\/\/ The error channel will return issues which may be intermittent. They are not\n\/\/ wrapped, so you can check them against the definitions in the reddit package\n\/\/ and choose to wait when Reddit is busy or the connection faults, instead of\n\/\/ failing.\n\/\/\n\/\/ If there is a problem setting up the stream, such as the endpoint being\n\/\/ invalid, that will be caught in the initial construction of the stream; you\n\/\/ don't need to worry about that on the error channel.\n\/\/\n\/\/ These streams will consume \"intervals\" of the Reddit handle given to them.\n\/\/ Since the reddit handlers are rate limited and do not allow bursts, there is\n\/\/ essentially a schedule on which they execute requests, and the executions\n\/\/ will be divided roughly evenly between the goroutines sharing the handle.\n\/\/ E.g. if you create two user streams which depend on a handle with a rate\n\/\/ limit of 5 seconds, each of them will be unblocked once every 10 seconds\n\/\/ (ish), since they each consume one interval, and the interval is 5 seconds.\npackage streams\n\nimport (\n\t\"strings\"\n\n\t\"github.com\/turnage\/graw\/reddit\"\n\n\t\"github.com\/turnage\/graw\/streams\/internal\/monitor\"\n\t\"github.com\/turnage\/graw\/streams\/internal\/rsort\"\n)\n\n\/\/ Subreddits returns a stream of new posts from the requested subreddits.

A leading '{' and\/or\n\/\/ a trailing '}' is optional and will be trimmed before further\n\/\/ parsing. Individual Matchers are separated by commas outside of quoted parts\n\/\/ of the input string. Those commas may be followed by whitespace. Parts of the\n\/\/ string inside unescaped double quotes ('\"…\"') are considered quoted (and\n\/\/ commas don't act as separators there). If double quotes are escaped with a\n\/\/ single backslash ('\\\"'), they are ignored for the purpose of identifying\n\/\/ quoted parts of the input string. If the input string, after trimming the\n\/\/ optional trailing '}', ends with a comma, followed by optional whitespace,\n\/\/ this comma and whitespace will be trimmed.\n\/\/\n\/\/ Examples for valid input strings:\n\/\/   {foo = \"bar\", dings != \"bums\", }\n\/\/   foo=bar,dings!=bums\n\/\/   {quote=\"She said: \\\"Hi, ladies! That's gender-neutral…\\\"\"}\n\/\/   statuscode=~\"5..\"\n\/\/\n\/\/ See ParseMatcher for details how an individual Matcher is parsed.\nfunc ParseMatchers(s string) ([]*Matcher, error) {\n\tmatchers := []*Matcher{}\n\ts = strings.TrimPrefix(s, \"{\")\n\ts = strings.TrimSuffix(s, \"}\")\n\n\tvar insideQuotes bool\n\tvar token string\n\tvar tokens []string\n\tfor _, r := range s {\n\t\tif !insideQuotes && r == ',' {\n\t\t\ttokens = append(tokens, token)\n\t\t\ttoken = \"\"\n\t\t\tcontinue\n\t\t}\n\t\ttoken += string(r)\n\t\tif r == '\"' {\n\t\t\tinsideQuotes = !insideQuotes\n\t\t}\n\t}\n\tif token != \"\" {\n\t\ttokens = append(tokens, token)\n\t}\n\tfor _, token := range tokens {\n\t\tm, err := ParseMatcher(token)\n\t\tif err != nil {\n\t\t\treturn nil, err\n\t\t}\n\t\tmatchers = append(matchers, m)\n\t}\n\n\treturn matchers, nil\n}\n\n\/\/ ParseMatcher parses a matcher with a syntax inspired by PromQL and\n\/\/ OpenMetrics. This syntax is convenient to describe filters and selectors in\n\/\/ UIs and config files. To support the interactive nature of the use cases, the\n\/\/ parser is in various aspects fairly tolerant.\n\/\/\n\/\/ The syntax of a matcher consists of three tokens: (1) A valid Prometheus\n\/\/ label name. (2) One of '=', '!=', '=~', or '!~', with the same meaning as\n\/\/ known from PromQL selectors. (3) A UTF-8 string, which may be enclosed in\n\/\/ double quotes. Before or after each token, there may be any amount of\n\/\/ whitespace, which will be discarded. The 3rd token may be the empty\n\/\/ string. Within the 3rd token, OpenMetrics escaping rules apply: '\\\"' for a\n\/\/ double-quote, '\\n' for a line feed, '\\\\' for a literal backslash. Unescaped\n\/\/ '\"' must not occur inside the 3rd token (only as the 1st or last\n\/\/ character). However, literal line feed characters are tolerated, as are\n\/\/ single '\\' characters not followed by '\\', 'n', or '\"'. They act as a literal\n\/\/ backslash in that case.\nfunc ParseMatcher(s string) (*Matcher, error) {\n\tvar (\n\t\tname, value string\n\t\tmatchType   MatchType\n\t)\n\n\tms := re.FindStringSubmatch(s)\n\tif len(ms) < 4 {\n\t\treturn nil, errors.Errorf(\"bad matcher format: %s\", s)\n\t}\n\n\tname = ms[1]\n\tif name == \"\" {\n\t\treturn nil, errors.New(\"failed to parse label name\")\n\t}\n\n\tmatchType, found := typeMap[ms[2]]\n\tif !found {\n\t\treturn nil, errors.New(\"failed to find match operator\")\n\t}\n\n\tif ms[3] != \"\" {\n\t\tvalue = ms[3]\n\t} else {\n\t\tvalue = ms[4]\n\t}\n\n\treturn NewMatcher(matchType, name, value)\n}\n<|endoftext|>"}

These are the versions written by the Python\n2.x series. Python 3 defines newer protocol versions, but can write the older\nprotocol versions so they are readable by this package.\n\nTLDR\n\nRead a pickled string or unicode object\n\tpickle.dumps(\"foobar\")\n\t---\n\tvar somePickledData io.Reader\n\tmystring, err := stalecucumber.String(stalecucumber.Unpickle(somePickledData))\n\nRead a pickled integer\n\tpickle.dumps(42)\n\t---\n\tvar somePickledData io.Reader\n\tmyint64, err := stalecucumber.Int(stalecucumber.Unpickle(somePickledData))\n\nRead a pickled list of numbers into a structure\n\tpickle.dumps([8,8,2006])\n\t---\n\tvar somePickledData io.Reader\n\tnumbers := make([]int64,0)\n\n\terr := stalecucumber.UnpackInto(&numbers).From(stalecucumber.Unpickle(somePickledData))\n\nRead a pickled dictionary into a structure\n\tpickle.dumps({\"apple\":1,\"banana\":2,cat:\"hello\",\"Dog\":42.0})\n\t---\n\tvar somePickledData io.Reader\n\tmystruct := struct{\n\t\tApple int\n\t\tBanana uint\n\t\tCat string\n\t\tDog float32}{}\n\n\terr := stalecucumber.UnpackInto(&mystruct).From(stalecucumber.Unpickle(somePickledData))\n\nReading Data\n\nThe stalecucumber.Unpickle function takes a reader and attempts to read\na complete pickle program from it. This is normally the output of the function\nlike \"pickle.dump\" from Python.\n\nThe returned type is interface{} because unpickling can generate any type. Use\na helper function to convert to another type without an additional type check.\n\nAn error is returned if the underlying reader fails, the program\nis invalid, or unsupported opcodes are encountered. See below for the details\nof unsupported opcodes.\n\nIf the version of python you are using supports protocol version 1 or 2,\nyou should always specify that protocol version. By default the \"pickle\"\nand \"cPickle\" modules in Python write using protocol 0. Protocol 0\nrequires much more space to represent the same values and is much\nslower to parse.\n\nType Conversions\n\nTypes conversion Python types to Go types is performed as followed\n\tint -> int64\n\tstring -> string\n\tunicode -> string\n\tfloat -> float64\n\tlong -> big.Int from the \"math\/big\" package\n\tlists -> []interface{}\n\ttuples -> []interface{}\n\tdict -> map[interface{}]interface{}\n\nThe following values are converted from Python to the Go types\n\tTrue & False -> bool\n\tNone -> stalecucumber.PickleNone\n\nHelper Functions\n\nThe following helper functions were inspired by the github.com\/garyburd\/redigo\npackage. Each function takes the result of Unpickle as its arguments. If unpickle\nfails it does nothing and returns that error. Otherwise it attempts to\nconvert to the appropriate type. If type conversion fails it returns an error\n\n\tString - string from Python string or unicode\n\tInt - int64 from Python int or long\n\tBool - bool from Python True or False\n\tBig - *big.Int from Python long\n\tListOrTuple - []interface{} from Python Tuple or List\n\tFloat - float64 from Python float\n\tDict - map[interface{}]interface{} from Python dictionary\n\tDictString -\n\t\tmap[string]interface{} from Python dictionary.\n\t\tKeys must all be of type unicode or string.\n\nUnpacking into structures\n\nIf the pickled object is a python dictionary that has only unicode and string\nobjects for keys, that object can be unpickled into a struct in Go by using\nthe \"UnpackInto\" function. The \"From\" receiver on the return value accepts\nthe result of \"Unpickle\" as its actual parameters.\n\nThe keys of the python dictionary are assigned to fields in a structure. If\nthe first character of the key is not uppercase, it is uppercased. If a field\nmatching that name is found, the value in the python dictionary is unpacked\ninto the value of the field within the structure.\n\nA list of python dictionaries can be unpickled into a slice of structures in\nGo.\n\nA homogeneous list of python values can be unpickled into a slice in\nGo with the appropriate element type.\n\nA nested python dictionary is unpickled into nested structures in Go. If a\nfield is of type map[interface{}]interface{} is of course unpacked into that\nas well.\n\nBy default UnpackInto skips any missing fields and fails if a field's\ntype is not compatible with the object's type.\n\nThis behavior can be changed by setting \"AllowMissingFields\" and\n\"AllowMismatchedFields\" on the return value of UnpackInto before calling\nFrom.\n\nRecursive objects\n\nYou can pickle recursive objects like so\n\n\ta = {}\n\ta[\"self\"] = a\n\tpickle.dumps(a)\n\nPython's pickler is intelligent enough not to emit an infinite data structure\nwhen a recursive object is pickled.\n\nI reccomend against pickling recursive objects in the first place, but this\nlibrary handles unpickling them without a problem. The result of unpickling\nthe above is map[interface{}]interface{} with a key \"a\" that contains\na reference to itself.\n\nAttempting to unpack the result of the above python code into a structure\nwith UnpackInto would either fail or recurse forever.\n\nUnsupported Opcodes\n\nThe pickle format is incredibly flexible and as a result has some\nfeatures that are impractical or unimportant when implementing a reader in\nanother language.\n\nEach set of opcodes is listed below by protocol version with the impact.\n\nProtocol 0\n\n\tGLOBAL\n\nThis opcode is equivalent to calling \"import foo; foo.bar\" in python. It is\ngenerated whenever an object instance, class definition, or method definition\nis serialized. As long as the pickled data does not contain an instance\nof a python class or a reference to a python callable this opcode is not\nemitted by the \"pickle\" module.\n\nA few examples of what will definitely cause this opcode to be emitted\n\n\tpickle.dumps(range) #Pickling the range function\n\tpickle.dumps(Exception()) #Pickling an instance of a python class\n\nThis opcode will be partially supported in a future revision to this package\nthat allows the unpickling of instances of Python classes.\n\n\tREDUCE\n\tBUILD\n\tINST\n\nThese opcodes are used in recreating pickled python objects.

{"text":"<commit_before>package query\n\nimport (\n\tgoprocess \"github.com\/jbenet\/goprocess\"\n)\n\n\/*\nQuery represents storage for any key-value pair.\n\ntl;dr:\n\n  queries are supported across datastores.\n  Cheap on top of relational dbs, and expensive otherwise.\n  Pick the right tool for the job!\n\nIn addition to the key-value store get and set semantics, datastore\nprovides an interface to retrieve multiple records at a time through\nthe use of queries. The datastore Query model gleans a common set of\noperations performed when querying. To avoid pasting here years of\ndatabase research, let’s summarize the operations datastore supports.\n\nQuery Operations:\n\n  * namespace - scope the query, usually by object type\n  * filters - select a subset of values by applying constraints\n  * orders - sort the results by applying sort conditions\n  * limit - impose a numeric limit on the number of results\n  * offset - skip a number of results (for efficient pagination)\n\ndatastore combines these operations into a simple Query class that allows\napplications to define their constraints in a simple, generic, way without\nintroducing datastore specific calls, languages, etc.\n\nOf course, different datastores provide relational query support across a\nwide spectrum, from full support in traditional databases to none at all in\nmost key-value stores. Datastore aims to provide a common, simple interface\nfor the sake of application evolution over time and keeping large code bases\nfree of tool-specific code. It would be ridiculous to claim to support high-\nperformance queries on architectures that obviously do not. Instead, datastore\nprovides the interface, ideally translating queries to their native form\n(e.g. into SQL for MySQL).\n\nHowever, on the wrong datastore, queries can potentially incur the high cost\nof performing the aforemantioned query operations on the data set directly in\nGo. It is the client’s responsibility to select the right tool for the job:\npick a data storage solution that fits the application’s needs now, and wrap\nit with a datastore implementation. As the needs change, swap out datastore\nimplementations to support your new use cases.

The datastore Query model gleans a common set of\noperations performed when querying. To avoid pasting here years of\ndatabase research, let’s summarize the operations datastore supports.\n\nQuery Operations:\n\n  * namespace - scope the query, usually by object type\n  * filters - select a subset of values by applying constraints\n  * orders - sort the results by applying sort conditions\n  * limit - impose a numeric limit on the number of results\n  * offset - skip a number of results (for efficient pagination)\n\ndatastore combines these operations into a simple Query class that allows\napplications to define their constraints in a simple, generic, way without\nintroducing datastore specific calls, languages, etc.\n\nOf course, different datastores provide relational query support across a\nwide spectrum, from full support in traditional databases to none at all in\nmost key-value stores. Datastore aims to provide a common, simple interface\nfor the sake of application evolution over time and keeping large code bases\nfree of tool-specific code. It would be ridiculous to claim to support high-\nperformance queries on architectures that obviously do not. Instead, datastore\nprovides the interface, ideally translating queries to their native form\n(e.g. into SQL for MySQL).\n\nHowever, on the wrong datastore, queries can potentially incur the high cost\nof performing the aforemantioned query operations on the data set directly in\nGo. It is the client’s responsibility to select the right tool for the job:\npick a data storage solution that fits the application’s needs now, and wrap\nit with a datastore implementation. As the needs change, swap out datastore\nimplementations to support your new use cases. Some applications, particularly\nin early development stages, can afford to incurr the cost of queries on non-\nrelational databases (e.g. using a FSDatastore and not worry about a database\nat all). When it comes time to switch the tool for performance, updating the\napplication code can be as simple as swapping the datastore in one place, not\nall over the application code base.

Such arguments come from various packages\nusing cgo, and the ordering of these arguments is, with current (go tool link),\ndependent on the order in which the cgo-using packages are found in a\nbreadth-first search following dependencies, starting from “main”.\n\nThus, if\n   import \"net\"\nis processed before\n   import \"…\/skopeo\/signature\"\nit will, in the next level of the BFS, pull in \"runtime\/cgo\" (a dependency of\n\"net\") before \"mtrmac\/gpgme\" (a dependency of \"…\/skopeo\/signature\"), causing\n-lpthread (used by \"runtime\/cgo\") to be used before -lgpgme.\n\nThis might be possible to work around by careful import ordering, or by removing\na direct dependency on \"net\", but that would be very fragile.\n\nSo, until the above bug is fixed, add -lgpgme directly in the \"main\" package\nto ensure the needed build order.\n\nUnfortunately, this workaround needs to be applied at the top level of any user\nof \"…\/skopeo\/signature\"; it cannot be added to \"…\/skopeo\/signature\" itself,\nby that time this package is first processed by the linker, a -lpthread may\nalready be queued and it would be too late.\n*\/\n\n\/\/ #cgo LDFLAGS: -lgpgme\nimport \"C\"\n<commit_msg>Remove cgo_pthread_ordering_workaround.go<commit_after><|endoftext|>"}

Filters create a larger\nfilter when joined with pipes \"|\".  And maintaining a stack of filters allows\nexploritory querying of JSON structures.\n\nFilters can be pushed onto the filter stack with \":push\" and popped with\n\":pop\".\n\n\t> :push .[]\n\t> :push .type\n\t> :pop\n\t> :push [.type,.name]\n\t> :pop 2\n\nThe corresponding jq filter at each step is\n\n\t.[]\n\t.[] | .type\n\t.[]\n\t.[] | [.type,.name]\n\t.\n\nNotice that in the last step the stack was emptied with \":pop 2\". But jqsh\nleaves a \".\" on the stack.\n\nRead more about jq filters at the tool's online manual.\n\n\thttp:\/\/stedolan.github.io\/jq\/manual\/#Basicfilters\n\nShell syntax\n\nThe current shell syntax is rudimentory but it suffices.  Commands are prefixed\nwith a colon ':' and a command name followed by a space separated list of\narguments.\n\n\t> :load test.json\n\nThe above loads the file \"test.json\" into the jqsh cache for inspection.  There\nis no quoting of arguments.  A plus '+' may be used on the last argument to\ninclude all charactors up to (but excluding) the next newline character.\n\n\t> :push +.items[] | select(.name | contains(\"hello\"))\n\nThe above pushes the filter `.items[] | select(.name | contains(\"hello\"))` on\nto the jqsh filter stack.

Filters create a larger\nfilter when joined with pipes \"|\".  And maintaining a stack of filters allows\nexploritory querying of JSON structures.\n\nFilters can be pushed onto the filter stack with \":push\" and popped with\n\":pop\".\n\n\t> :push .[]\n\t> :push .type\n\t> :pop\n\t> :push [.type,.name]\n\t> :pop 2\n\nThe corresponding jq filter at each step is\n\n\t.[]\n\t.[] | .type\n\t.[]\n\t.[] | [.type,.name]\n\t.\n\nNotice that in the last step the stack was emptied with \":pop 2\". But jqsh\nleaves a \".\" on the stack.\n\nRead more about jq filters at the tool's online manual.\n\n\thttp:\/\/stedolan.github.io\/jq\/manual\/#Basicfilters\n\nShell syntax\n\nThe current shell syntax is rudimentory but it suffices.  Commands are prefixed\nwith a colon ':' and a command name followed by a space separated list of\narguments.\n\n\t> :load test.json\n\nThe above loads the file \"test.json\" into the jqsh cache for inspection.  There\nis no quoting of arguments.  A plus '+' may be used on the last argument to\ninclude all charactors up to (but excluding) the next newline character.\n\n\t> :push +.items[] | select(.name | contains(\"hello\"))\n\nThe above pushes the filter `.items[] | select(.name | contains(\"hello\"))` on\nto the jqsh filter stack. Filters can be removed from the filter stack with \":pop\".\n\n\t> :pop\n\n\n\t:<cmd> <arg1> <arg2> ...    execute cmd with the given arguments\n\t:<cmd> ... +<argN>          execute cmd with an argument containing spaces (argN)\n\t.                           shorthand for \":write\"\n\t..                          shorthand for \":pop\"\n\t?<filter>                   shorthand for \":peek +<filter>\"\n\t<filter>                    shorthand for \":push +<filter>\"\n\nNote that \".\" is a valid jq filter but pushing it on the filter stack lacks\nsemantic value.

Go handles the use of other packages elegantly, but is\nprone to problems when that code has breaking changes or is removed from the\nInternet. As a solution, the FAQ suggests copying any third party repositories\ninto your own project and changing your import paths to match. This is a\nrecursive process, as you must then perform the same procedure for those copied\npackages and so on, until all leaf packages have no external imports.\n\nparty is a tool that performs all of this work. It:\n\n1. Rewrites all external imports in both your project and the third party\ndirectory from \"other.com\/user\/package\" to\n\"host.com\/user\/your_project\/_third_party\/other.com\/user\/package\".\n\n2. Updates or copies files from \"$GOPATH\/src\/other.com\/user\/package\" to\n\"$GOPATH\/src\/host.com\/user\/your_project\/_third_party\/other.com\/user\/package\".\n\n3. Returns to step 1 until no more rewrites are performed.\n\nUsage\n\nFrom your project's root directory, for the first run:\n\n\t$ party -c\n\nSubsequent invocations can omit -c.\n\nThe flags are:\n\t-c\n\t\tcreate the third party directory if it does not exist\n\t-u\n\t\trun \"go get -d -u <pkg>\" on packages imported by party for the\n\t\tcurrent package\n\t-d=\"_third_party\"\n\t\tset the third party directory\n\t-v\n\t\tenable verbose output\n\t-n\n\t\tdry run: actions are printed instead of run\n\t-r\n\t\timport third party packages as relative, local imports\n\nApp Engine and Relative Imports\n\nWhen working on an App Engine project, use the -r flag. This will cause all\nthird party imports to be local packages. This is needed because otherwise App\nEngine will run init() routines from your .go files twice if your app is also in\nyour $GOPATH.\n\nBugs\n\nThere is no guarantee that the source directory exists. For example, a package\nmay have a OS-specific file (file_windows.go) which imports another package. On\nnon-Windows, that other package will not have been fetched during \"go get\" and\nwill thus not exist. These packages must be fetched using \"go get\" or some other\nmethod by hand. Or, running party on a Windows machine (in this case) will\ncorrectly copy those files.

Go handles the use of other packages elegantly, but is\nprone to problems when that code has breaking changes or is removed from the\nInternet. As a solution, the FAQ suggests copying any third party repositories\ninto your own project and changing your import paths to match. This is a\nrecursive process, as you must then perform the same procedure for those copied\npackages and so on, until all leaf packages have no external imports.\n\nparty is a tool that performs all of this work. It:\n\n1. Rewrites all external imports in both your project and the third party\ndirectory from \"other.com\/user\/package\" to\n\"host.com\/user\/your_project\/_third_party\/other.com\/user\/package\".\n\n2. Updates or copies files from \"$GOPATH\/src\/other.com\/user\/package\" to\n\"$GOPATH\/src\/host.com\/user\/your_project\/_third_party\/other.com\/user\/package\".\n\n3. Returns to step 1 until no more rewrites are performed.\n\nUsage\n\nFrom your project's root directory, for the first run:\n\n\t$ party -c\n\nSubsequent invocations can omit -c.\n\nThe flags are:\n\t-c\n\t\tcreate the third party directory if it does not exist\n\t-u\n\t\trun \"go get -d -u <pkg>\" on packages imported by party for the\n\t\tcurrent package\n\t-d=\"_third_party\"\n\t\tset the third party directory\n\t-v\n\t\tenable verbose output\n\t-n\n\t\tdry run: actions are printed instead of run\n\t-r\n\t\timport third party packages as relative, local imports\n\nApp Engine and Relative Imports\n\nWhen working on an App Engine project, use the -r flag. This will cause all\nthird party imports to be local packages. This is needed because otherwise App\nEngine will run init() routines from your .go files twice if your app is also in\nyour $GOPATH.\n\nBugs\n\nThere is no guarantee that the source directory exists. For example, a package\nmay have a OS-specific file (file_windows.go) which imports another package. On\nnon-Windows, that other package will not have been fetched during \"go get\" and\nwill thus not exist. These packages must be fetched using \"go get\" or some other\nmethod by hand. Or, running party on a Windows machine (in this case) will\ncorrectly copy those files. These cases are reported when running party.\n\nparty performs the equivalent of gofmt on any files affected by the import\nrewrite, thus the diff may be somewhat larger than just the import lines.\n\nThird party imports that use local (relative) packages will fail, as those\npackages are assumed to be part of the standard library. Those packages will not\nbe copied.\n\n*\/\npackage main\n\nimport (\n\t\"bytes\"\n\t\"flag\"\n\t\"fmt\"\n\t\"go\/ast\"\n\t\"go\/format\"\n\t\"go\/parser\"\n\t\"go\/printer\"\n\t\"go\/token\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"path\"\n\t\"path\/filepath\"\n\t\"strconv\"\n\t\"strings\"\n\n\t\"code.google.com\/p\/go.tools\/astutil\"\n)\n\nconst dirMode os.FileMode = 0755\n\nvar (\n\tdryrun     = flag.Bool(\"n\", false, \"don't perform any action, instead print them\")\n\tcreate     = flag.Bool(\"c\", false, \"create the third party directory if needed\")\n\trelative   = flag.Bool(\"r\", false, \"use a relative third party directory (needed on App Engine)\")\n\tverbose    = flag.Bool(\"v\", false, \"print actions\")\n\tthirdParty = flag.String(\"d\", \"_third_party\", \"name of third party directory\")\n\tflagUpdate = flag.Bool(\"u\", false, \"update (go get -d -u) used packages\")\n\n\trelpath, gopath, ThirdParty string\n)\n\nfunc main() {\n\tflag.Parse()\n\tif *dryrun {\n\t\t*verbose = true\n\t}\n\n\tThirdParty = filepath.Base(*thirdParty)\n\tif ThirdParty != *thirdParty {\n\t\tlog.Fatal(\"third party directory cannot contain path separators\")\n\t}\n\tif *create {\n\t\tos.Mkdir(ThirdParty, dirMode)\n\t}\n\tif _, err := os.Open(ThirdParty);

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

{"text":"<commit_before>\/*\n\nPackage golden is a package designed to make it possible to compare a game to a\ngolden run for testing purposes. It takes a record saved in storage\/filesystem\nformat and compares it.\n\nTypical Use\n\nTypically you generate a new set of goldens by cd'ing into the package\ncontaining the game you want to test. Then you run `boardgame-util\ncreate-golden`, which generates a stub server for that game. As you play and\ncreate games, it will save the records as filesystem.record.Record, a format\nthat is designed to be easy to read and modify as JSON. `create-golden` also\nwill save a `golden_test.go` which will, when tests are run, compare the current\nGameManager's operation to the states and moves saved in the golden json blobs.\nThese tests are a great way to verify that the behavior of your game does not\naccidentlaly change.\n\nThe format of filesystem.record.Record is optimized to be able to be\nhand-edited. It does a number of tricks to make sure that states and moves can\nbe spliced in easily. First and foremost, it typically stores subsequent states\nnot as full blobs but as diffs from the state before. This means that changing\none state doesn't require also modifying all subsequent states to have the same\nvalues. The format also \"relativizes\" moves, setting their Version to -1,\nsignifying that when fetched via record.Move(version), it should just use the\nversion number it said it was. In addition, the Initiator field is stored as a\nrelative number for how many moves back in history to go to. Finally, the\nTimestamp field is stored in a format that is as many seconds past the Unix\nepoch as the move is from the Game's Created timestamp. All of these properties\nmean that the format is (relatively) easy to tweak manually to add or remove\nmoves.\n\nYou can also add a \"Description\" top-level field in the json to describe what\nthe game is testing, which is useful to keep track of goldens that test various\nedge cases.\n\nRemastering Goldens\n\nTypically you record a golden, and then every time you test the game package, it\nwill just verify the game logic still applies the same moves in the right order,\nwith the right state modifications. But every so often you want to 'remaster'\nyour golden. For example, perhaps the game logic has changed to have slightly\ndifferent behavior, or you want to update the format of the golden to ensure\nit's canonical and up-to-date, to match changes in the underlying library.\n\nIt's possible to 'remaster' goldens, which means to re-record them and overwrite\nthe original. You do this by passing true as the last value to Compare or\nCompareFolder. The `golden_test.go` that is generated for you will also\nautomatically add a flag that will be passed in, so the canonical way to\nremaster is to run `go test -update-golden`, which instead of comparing the\ngolden, will remaster it, overwriting the original.\n\nAfter you remaster, it's a good idea to sanity check by doing a normal test (`go\ntest`) to verify the game logic matches the new golden. You should also visually\ninspect the diff of the golden before commiting to make sure there aren't any\nunintended changes. The remastering process is designed to ensure that wherever\npossible content doesn't change. The design of filesystem.record.Record\n(described above) helps, but the remastering process also seeks to, for example,\nuse existing timestamps wherever possible and generate reasonable intermediate\ntimestamps for new moves that have been added.\n\n*\/\npackage golden\n\nimport (\n\t\"bytes\"\n\t\"encoding\/json\"\n\t\"errors\"\n\t\"fmt\"\n\t\"io\/ioutil\"\n\t\"path\/filepath\"\n\t\"reflect\"\n\t\"strings\"\n\n\t\"github.com\/go-test\/deep\"\n\t\"github.com\/jkomoros\/boardgame\"\n\t\"github.com\/jkomoros\/boardgame\/storage\/filesystem\/record\"\n\t\"github.com\/sirupsen\/logrus\"\n\t\"github.com\/yudai\/gojsondiff\"\n\t\"github.com\/yudai\/gojsondiff\/formatter\"\n)\n\n\/\/Compare is the primary method in the package. It takes a game delegate and a\n\/\/filename denoting a record to compare against. delegate shiould be a fresh\n\/\/delegate not yet affiliated with a manager. It compares every version and move\n\/\/in the history (ignoring things that shouldn't be the same, like timestamps)\n\/\/and reports the first place they divrge. Any time it finds a move not proposed\n\/\/by AdminPlayerIndex it will propose that move. As long as your game uses\n\/\/state.Rand() for all randomness and is otherwise deterministic then everything\n\/\/should work. If updateOnDifferent is true, instead of erroring, it will\n\/\/instead overwrite the existing golden with a new one.

All of these properties\nmean that the format is (relatively) easy to tweak manually to add or remove\nmoves.\n\nYou can also add a \"Description\" top-level field in the json to describe what\nthe game is testing, which is useful to keep track of goldens that test various\nedge cases.\n\nRemastering Goldens\n\nTypically you record a golden, and then every time you test the game package, it\nwill just verify the game logic still applies the same moves in the right order,\nwith the right state modifications. But every so often you want to 'remaster'\nyour golden. For example, perhaps the game logic has changed to have slightly\ndifferent behavior, or you want to update the format of the golden to ensure\nit's canonical and up-to-date, to match changes in the underlying library.\n\nIt's possible to 'remaster' goldens, which means to re-record them and overwrite\nthe original. You do this by passing true as the last value to Compare or\nCompareFolder. The `golden_test.go` that is generated for you will also\nautomatically add a flag that will be passed in, so the canonical way to\nremaster is to run `go test -update-golden`, which instead of comparing the\ngolden, will remaster it, overwriting the original.\n\nAfter you remaster, it's a good idea to sanity check by doing a normal test (`go\ntest`) to verify the game logic matches the new golden. You should also visually\ninspect the diff of the golden before commiting to make sure there aren't any\nunintended changes. The remastering process is designed to ensure that wherever\npossible content doesn't change. The design of filesystem.record.Record\n(described above) helps, but the remastering process also seeks to, for example,\nuse existing timestamps wherever possible and generate reasonable intermediate\ntimestamps for new moves that have been added.\n\nIf you have changed your game logic (for example, adding a new FixUp move that\ndidn't exist before), then your old goldens will no longer match, so `go test`\nwill fail, and you'll need to remaster your goldens. In the common case where\nthe new FixUp move occurs within a run of already-existing FixUp moves, then you\ndon't need to do anything special; `go test -update-golden`, combined with a\nmanual sanity check of the diff, should be sufficient.\n\nIn the case where you have added a new Player move, or a move like SeatPlayer\nthat occurs on its own, you'll need to do a bit of manual surgery. Before\nremastering, splice in a move record corresponding to the new move into the\nright place in the golden's Move section. Note that you'll need to update the\nInitiator fields of any other moves that come in the immediate fixup run\nimmediately after it, to verify that their relative value points to the new\ninitator. You do not need to update the state patches to match. Then, run `go\ntest -update-golden` and verify the output looks correct. Note that your manual\nsplice will now have been overwritten, which means that if the output was wrong,\nyou'll need to reset it, manually modify again, and then remaster.\n\n*\/\npackage golden\n\nimport (\n\t\"bytes\"\n\t\"encoding\/json\"\n\t\"errors\"\n\t\"fmt\"\n\t\"io\/ioutil\"\n\t\"path\/filepath\"\n\t\"reflect\"\n\t\"strings\"\n\n\t\"github.com\/go-test\/deep\"\n\t\"github.com\/jkomoros\/boardgame\"\n\t\"github.com\/jkomoros\/boardgame\/storage\/filesystem\/record\"\n\t\"github.com\/sirupsen\/logrus\"\n\t\"github.com\/yudai\/gojsondiff\"\n\t\"github.com\/yudai\/gojsondiff\/formatter\"\n)\n\n\/\/Compare is the primary method in the package. It takes a game delegate and a\n\/\/filename denoting a record to compare against. delegate shiould be a fresh\n\/\/delegate not yet affiliated with a manager. It compares every version and move\n\/\/in the history (ignoring things that shouldn't be the same, like timestamps)\n\/\/and reports the first place they divrge. Any time it finds a move not proposed\n\/\/by AdminPlayerIndex it will propose that move. As long as your game uses\n\/\/state.Rand() for all randomness and is otherwise deterministic then everything\n\/\/should work. If updateOnDifferent is true, instead of erroring, it will\n\/\/instead overwrite the existing golden with a new one.

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.

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.

If there is no such element, delete is a no-op.\n\/\/ If m is nil, delete panics.\nfunc delete(m map[Type]Type1, key Type)\n\n\/\/ The len built-in function returns the length of v, according to its type:\n\/\/\tArray: the number of elements in v.\n\/\/\tPointer to array: the number of elements in *v (even if v is nil).\n\/\/\tSlice, or map: the number of elements in v; if v is nil, len(v) is zero.\n\/\/\tString: the number of bytes in v.\n\/\/\tChannel: the number of elements queued (unread) in the channel buffer;\n\/\/\tif v is nil, len(v) is zero.\nfunc len(v Type) int\n\n\/\/ The cap built-in function returns the capacity of v, according to its type:\n\/\/\tArray: the number of elements in v (same as len(v)).\n\/\/\tPointer to array: the number of elements in *v (same as len(v)).\n\/\/\tSlice: the maximum length the slice can reach when resliced;\n\/\/\tif v is nil, cap(v) is zero.\n\/\/\tChannel: the channel buffer capacity, in units of elements;\n\/\/\tif v is nil, cap(v) is zero.\nfunc cap(v Type) int\n\n\/\/ The make built-in function allocates and initializes an object of type\n\/\/ slice, map, or chan (only). Like new, the first argument is a type, not a\n\/\/ value. Unlike new, make's return type is the same as the type of its\n\/\/ argument, not a pointer to it. The specification of the result depends on\n\/\/ the type:\n\/\/\tSlice: The size specifies the length. The capacity of the slice is\n\/\/\tequal to its length. A second integer argument may be provided to\n\/\/\tspecify a different capacity; it must be no smaller than the\n\/\/\tlength, so make([]int, 0, 10) allocates a slice of length 0 and\n\/\/\tcapacity 10.\n\/\/\tMap: An initial allocation is made according to the size but the\n\/\/\tresulting map has length 0. The size may be omitted, in which case\n\/\/\ta small starting size is allocated.\n\/\/\tChannel: The channel's buffer is initialized with the specified\n\/\/\tbuffer capacity. If zero, or the size is omitted, the channel is\n\/\/\tunbuffered.\nfunc make(Type, size IntegerType) Type\n\n\/\/ The new built-in function allocates memory. The first argument is a type,\n\/\/ not a value, and the value returned is a pointer to a newly\n\/\/ allocated zero value of that type.\nfunc new(Type) *Type\n\n\/\/ The complex built-in function constructs a complex value from two\n\/\/ floating-point values. The real and imaginary parts must be of the same\n\/\/ size, either float32 or float64 (or assignable to them), and the return\n\/\/ value will be the corresponding complex type (complex64 for float32,\n\/\/ complex128 for float64).\nfunc complex(r, i FloatType) ComplexType\n\n\/\/ The real built-in function returns the real part of the complex number c.\n\/\/ The return value will be floating point type corresponding to the type of c.\nfunc real(c ComplexType) FloatType\n\n\/\/ The imag built-in function returns the imaginary part of the complex\n\/\/ number c. The return value will be floating point type corresponding to\n\/\/ the type of c.\nfunc imag(c ComplexType) FloatType\n\n\/\/ The close built-in function closes a channel, which must be either\n\/\/ bidirectional or send-only. It should be executed only by the sender,\n\/\/ never the receiver, and has the effect of shutting down the channel after\n\/\/ the last sent value is received. After the last value has been received\n\/\/ from a closed channel c, any receive from c will succeed without\n\/\/ blocking, returning the zero value for the channel element. The form\n\/\/\tx, ok := <-c\n\/\/ will also set ok to false for a closed channel.\nfunc close(c chan<- Type)\n\n\/\/ The panic built-in function stops normal execution of the current\n\/\/ goroutine. When a function F calls panic, normal execution of F stops\n\/\/ immediately. Any functions whose execution was deferred by F are run in\n\/\/ the usual way, and then F returns to its caller. To the caller G, the\n\/\/ invocation of F then behaves like a call to panic, terminating G's\n\/\/ execution and running any deferred functions. This continues until all\n\/\/ functions in the executing goroutine have stopped, in reverse order. At\n\/\/ that point, the program is terminated and the error condition is reported,\n\/\/ including the value of the argument to panic. This termination sequence\n\/\/ is called panicking and can be controlled by the built-in function\n\/\/ recover.\nfunc panic(v interface{})\n\n\/\/ The recover built-in function allows a program to manage behavior of a\n\/\/ panicking goroutine. Executing a call to recover inside a deferred\n\/\/ function (but not any function called by it) stops the panicking sequence\n\/\/ by restoring normal execution and retrieves the error value passed to the\n\/\/ call of panic. If recover is called outside the deferred function it will\n\/\/ not stop a panicking sequence. In this case, or when the goroutine is not\n\/\/ panicking, or if the argument supplied to panic was nil, recover returns\n\/\/ nil. Thus the return value from recover reports whether the goroutine is\n\/\/ panicking.\nfunc recover() interface{}\n\n\/\/ The error built-in interface type is the conventional interface for\n\/\/ representing an error condition, with the nil value representing no error.\ntype error interface {\n\tError() string\n}\n<commit_msg>builtin: correct comment on builtin function delete().<commit_after>\/\/ Copyright 2011 The Go Authors.

The\n\/\/   best fit is when the interval is >= the rawInterval (first retention) and\n\/\/   less then the interval of the next rollup.\n\/\/ - If the pattern doesnt match, then we skip ahead to the next pattern.\n\/\/\n\/\/ eg. from the above diagram we would compare the pattern for schame0\n\/\/     (pattern1), if it doesnt match we will then compare the pattern of\n\/\/     schema2 (pattern2) and if that doesnt match we would try schema5\n\/\/     (pattern3).\nfunc (s Schemas) Match(metric string, interval int) (uint16, Schema) {\n\ti := 0\n\tfor i < len(s.index) {\n\t\tschema := s.index[i]\n\t\tif schema.Pattern.MatchString(metric) {\n\t\t\t\/\/ no interval passed,use the raw retentions.\n\t\t\t\/\/ This is primarily used by the carbon input plugin.\n\t\t\tif interval == 0 {\n\t\t\t\treturn uint16(i), schema\n\t\t\t}\n\t\t\t\/\/ search through the retentions to find the first one where\n\t\t\t\/\/ the metric interval is < SecondsPerPoint of the retention.\n\t\t\t\/\/ The schema is then the previous retention.\n\t\t\tfor j, ret := range schema.Retentions.Rets {\n\t\t\t\tif interval < ret.SecondsPerPoint {\n\t\t\t\t\t\/\/ if there are no retentions with SecondsPerPoint <= interval (j==0)\n\t\t\t\t\t\/\/ then we need to use the first retention.

{"text":"<commit_before>\/*\n\nPackage filesystem is a storage layer that stores information about games as\nJSON files within a given folder, (or somewhere nested in a folder within base\nfolder) one per game. It's extremely inefficient and doesn't even persist\nextended game information to disk. It's most useful for cases where having an\neasy-to-read, diffable representation for games makes sense, for example to\ncreate golden tester games for use in testing.\n\nfilesystem stores files in the given base folder.

It's extremely inefficient and doesn't even persist\nextended game information to disk. It's most useful for cases where having an\neasy-to-read, diffable representation for games makes sense, for example to\ncreate golden tester games for use in testing.\n\nfilesystem stores files in the given base folder.
