Probably requires a different MutatorUtil\n\/\/ representation.\n\/\/\n\/\/ When a window size is selected, show a second plot of the mutator\n\/\/ utilization distribution for that window size.\n\/\/\n\/\/ Render plot progressively so rough outline is visible quickly even\n\/\/ for very complex MUTs. Start by computing just a few window sizes\n\/\/ and then add more window sizes.\n\/\/\n\/\/ Consider using sampling to compute an approximate MUT. This would\n\/\/ work by sampling the mutator utilization at randomly selected\n\/\/ points in time in the trace to build an empirical distribution. We\n\/\/ could potentially put confidence intervals on these estimates and\n\/\/ render this progressively as we refine the distributions.\n\npackage main\n\nimport (\n\t\"encoding\/json\"\n\t\"fmt\"\n\ttrace \"internal\/traceparser\"\n\t\"log\"\n\t\"math\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n\t\"time\"\n)\n\nfunc init() {\n\thttp.HandleFunc(\"\/mmu\", httpMMU)\n\thttp.HandleFunc(\"\/mmuPlot\", httpMMUPlot)\n\thttp.HandleFunc(\"\/mmuDetails\", httpMMUDetails)\n}\n\nvar utilFlagNames = map[string]trace.UtilFlags{\n\t\"perProc\":    trace.UtilPerProc,\n\t\"stw\":        trace.UtilSTW,\n\t\"background\": trace.UtilBackground,\n\t\"assist\":     trace.UtilAssist,\n\t\"sweep\":      trace.UtilSweep,\n}\n\ntype mmuCacheEntry struct {\n\tinit     sync.Once\n\tutil     [][]trace.MutatorUtil\n\tmmuCurve *trace.MMUCurve\n\terr      error\n}\n\nvar mmuCache struct {\n\tm    map[trace.UtilFlags]*mmuCacheEntry\n\tlock sync.Mutex\n}\n\nfunc init() {\n\tmmuCache.m = make(map[trace.UtilFlags]*mmuCacheEntry)\n}\n\nfunc getMMUCurve(r *http.Request) ([][]trace.MutatorUtil, *trace.MMUCurve, error) {\n\tvar flags trace.UtilFlags\n\tfor _, flagStr := range strings.Split(r.FormValue(\"flags\"), \"|\") {\n\t\tflags |= utilFlagNames[flagStr]\n\t}\n\n\tmmuCache.lock.Lock()\n\tc := mmuCache.m[flags]\n\tif c == nil {\n\t\tc = new(mmuCacheEntry)\n\t\tmmuCache.m[flags] = c\n\t}\n\tmmuCache.lock.Unlock()\n\n\tc.init.Do(func() {\n\t\ttr, err := parseTrace()\n\t\tif err != nil {\n\t\t\tc.err = err\n\t\t} else {\n\t\t\tc.util = tr.MutatorUtilization(flags)\n\t\t\tc.mmuCurve = trace.NewMMUCurve(c.util)\n\t\t}\n\t})\n\treturn c.util, c.mmuCurve, c.err\n}\n\n\/\/ httpMMU serves the MMU plot page.\nfunc httpMMU(w http.ResponseWriter, r *http.Request) {\n\thttp.ServeContent(w, r, \"\", time.Time{}, strings.NewReader(templMMU))\n}\n\n\/\/ httpMMUPlot serves the JSON data for the MMU plot.\nfunc httpMMUPlot(w http.ResponseWriter, r *http.Request) {\n\tmu, mmuCurve, err := getMMUCurve(r)\n\tif err != nil {\n\t\thttp.Error(w, fmt.Sprintf(\"failed to parse events: %v\", err), http.StatusInternalServerError)\n\t\treturn\n\t}\n\n\tvar quantiles []float64\n\tfor _, flagStr := range strings.Split(r.FormValue(\"flags\"), \"|\") {\n\t\tif flagStr == \"mut\" {\n\t\t\tquantiles = []float64{0, 1 - .999, 1 - .99, 1 - .95}\n\t\t\tbreak\n\t\t}\n\t}\n\n\t\/\/ Find a nice starting point for the plot.\n\txMin := time.Second\n\tfor xMin > 1 {\n\t\tif mmu := mmuCurve.MMU(xMin);

Adding a new label to the object that the federation is\n\t\/\/ unaware of causes problems because federated controllers compare\n\t\/\/ the objects in federation and their equivalents in clusters and\n\t\/\/ try to reconcile them.

They can update an\n\t\/\/ object's status though. Therefore, this daemonset hash should\n\t\/\/ be a field in daemonset's status, not a label in object meta.\n\t\/\/ @janetkuo says that this label is only a short term solution. In\n\t\/\/ the near future, they are going to replace it with revision numbers\n\t\/\/ in daemonset status. We can then rip this bandaid out.\n\t\/\/\n\t\/\/ We are deleting the keys here and that should be fine since we are\n\t\/\/ working on object copies. Also, propagating the deleted labels\n\t\/\/ should also be fine because we don't support daemonset rolling\n\t\/\/ update in federation yet.\n\tdelete(daemonset1.ObjectMeta.Labels,

It exists so the unified IR linker can refer back to it\n\/\/ later.\nvar localPkgReader *pkgReader\n\n\/\/ unified constructs the local package's Internal Representation (IR)\n\/\/ from its syntax tree (AST).\n\/\/\n\/\/ The pipeline contains 2 steps:\n\/\/\n\/\/  1. Generate the export data \"stub\".\n\/\/\n\/\/  2. Generate the IR from the export data above.\n\/\/\n\/\/ The package data \"stub\" at step (1) contains everything from the local package,\n\/\/ but nothing that has been imported. When we're actually writing out export data\n\/\/ to the output files (see writeNewExport), we run the \"linker\", which:\n\/\/\n\/\/   - Updates compiler extensions data (e.g. inlining cost, escape analysis results).\n\/\/\n\/\/   - Handles re-exporting any transitive dependencies.\n\/\/\n\/\/   - Prunes out any unnecessary details (e.g. non-inlineable functions, because any\n\/\/     downstream importers only care about inlinable functions).\n\/\/\n\/\/ The source files are typechecked twice: once before writing the export data\n\/\/ using types2, and again after reading the export data using gc\/typecheck.\n\/\/ The duplication of work will go away once we only use the types2 type checker,\n\/\/ removing the gc\/typecheck step. For now, it is kept because:\n\/\/\n\/\/   - It reduces the engineering costs in maintaining a fork of typecheck\n\/\/     (e.g. no need to backport fixes like CL 327651).\n\/\/\n\/\/   - It makes it easier to pass toolstash -cmp.\n\/\/\n\/\/   - Historically, we would always re-run the typechecker after importing a package,\n\/\/     even though we know the imported data is valid. It's not ideal, but it's\n\/\/     not causing any problems either.\n\/\/\n\/\/   - gc\/typecheck is still in charge of some transformations, such as rewriting\n\/\/     multi-valued function calls or transforming ir.OINDEX to ir.OINDEXMAP.\n\/\/\n\/\/ Using the syntax tree with types2, which has a complete representation of generics,\n\/\/ the unified IR has the full typed AST needed for introspection during step (1).\n\/\/ In other words, we have all the necessary information to build the generic IR form\n\/\/ (see writer.captureVars for an example).\nfunc unified(noders []*noder) {\n\tinline.NewInline = InlineCall\n\n\tdata := writePkgStub(noders)\n\n\t\/\/ We already passed base.Flag.Lang to types2 to handle validating\n\t\/\/ the user's source code.

It exists so the unified IR linker can refer back to it\n\/\/ later.\nvar localPkgReader *pkgReader\n\n\/\/ unified constructs the local package's Internal Representation (IR)\n\/\/ from its syntax tree (AST).\n\/\/\n\/\/ The pipeline contains 2 steps:\n\/\/\n\/\/  1. Generate the export data \"stub\".\n\/\/\n\/\/  2. Generate the IR from the export data above.\n\/\/\n\/\/ The package data \"stub\" at step (1) contains everything from the local package,\n\/\/ but nothing that has been imported. When we're actually writing out export data\n\/\/ to the output files (see writeNewExport), we run the \"linker\", which:\n\/\/\n\/\/   - Updates compiler extensions data (e.g. inlining cost, escape analysis results).\n\/\/\n\/\/   - Handles re-exporting any transitive dependencies.\n\/\/\n\/\/   - Prunes out any unnecessary details (e.g. non-inlineable functions, because any\n\/\/     downstream importers only care about inlinable functions).\n\/\/\n\/\/ The source files are typechecked twice: once before writing the export data\n\/\/ using types2, and again after reading the export data using gc\/typecheck.\n\/\/ The duplication of work will go away once we only use the types2 type checker,\n\/\/ removing the gc\/typecheck step. For now, it is kept because:\n\/\/\n\/\/   - It reduces the engineering costs in maintaining a fork of typecheck\n\/\/     (e.g. no need to backport fixes like CL 327651).\n\/\/\n\/\/   - It makes it easier to pass toolstash -cmp.\n\/\/\n\/\/   - Historically, we would always re-run the typechecker after importing a package,\n\/\/     even though we know the imported data is valid. It's not ideal, but it's\n\/\/     not causing any problems either.\n\/\/\n\/\/   - gc\/typecheck is still in charge of some transformations, such as rewriting\n\/\/     multi-valued function calls or transforming ir.OINDEX to ir.OINDEXMAP.\n\/\/\n\/\/ Using the syntax tree with types2, which has a complete representation of generics,\n\/\/ the unified IR has the full typed AST needed for introspection during step (1).\n\/\/ In other words, we have all the necessary information to build the generic IR form\n\/\/ (see writer.captureVars for an example).\nfunc unified(noders []*noder) {\n\tinline.NewInline = InlineCall\n\n\tdata := writePkgStub(noders)\n\n\t\/\/ We already passed base.Flag.Lang to types2 to handle validating\n\t\/\/ the user's source code.

This makes it\npossible to run scollector correctly with zero configuration or command line\nflags.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support, which is\ncurrently only present in the \"next\" branch\n(https:\/\/github.com\/opentsdb\/opentsdb\/tree\/next). Ensure that is in use if not\nusing the docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nExternal collectors are executables that scollector invokes, collects output\nfrom, and uses that like other collector data. The -c option specfies the\nexternal collectors directory. It should contain numbered directories like\nOpenTSDB tcollector expects. Any executable file in those directories is run\nevery N seconds, where N is the name of the directory. Use 0 for a program that\nshould be run continuously and simply pass data through to OpenTSDB (the program\nwill be restarted if it exits). Data output format is:\n\n\tmetric timestamp value tag1=val1 tag2=val2 ...\n\nTimestamp is in Unix format (seconds since epoch). Tags are optional. A host tag\nis automatically added, but overridden if specified. Stderr output is passed to\nscollector's log.\n\nConfiguration File\n\nIf scollector.conf exists in the same directory as the scollector executable, it\nwill set configuration flags. Configuration file values overwrite command line\nflags. The configuration file is of the form key = value, one per line.\nSupported keys are: host (-h), hostname (-hostname), filter (-f), coldir (-c),\nsnmp (-s), icmp (-i), vsphere (-v). Example:\n\n\thost = other-tsdb:1234\n\tfilter = snmp\n\tsnmp = com@theswitch\n\nWindows\n\nscollector has full Windows support. It can be run standalone, or installed as a\nservice (see -winsvc). The Event Log is used when installed as a service.\n\nSNMP\n\nBy default, scollector will collect data from the current host and report it to\nthe TSDB server. scollector has an SNMP mode where it instead polls a given\nhost:\n\n\tscollector -s community@host[,community@host...]\n\nPoll frequency currently defaults to 5 minutes. Some common OIDs regarding\ninterfaces are collected. Others can be added easily.\n\n*\/\npackage main\n<commit_msg>cmd\/scollector: update doc.go documentation<commit_after>\/*\n\nScollector is a metric collection agent for OpenTSDB 2.0 and http:\/\/Bosun.org\n\ntcollector (https:\/\/github.com\/OpenTSDB\/tcollector) is OpenTSDB's data\ncollection framework built for OpenTSDB 1.0. scollector aims to be tcollector\nfor OpenTSDB 2.0 and is one method of sending data to Bosun for monitoring.\n\nUnlike tcollector, scollector is a single binary where all collectors are\ncompiled into scollector itself. scollector supports external collectors, but\nyour goal should be to use those temporarily until the go version is written or\nthe target system send data directly to OpenTSDB or Bosun. scollector has\nnative collectors for Linux, Darwin, and Windows and can pull data from other\nsystems such as AWS, SNMP, and vSphere.\n\nUsage:\n\tscollector [flag]\n\nThe flags are:\n\t-aws=\"\"\n\t    AWS keys and region, format: \"access_key:secret_key@region\".\n\t-b=0\n\t    OpenTSDB batch size.

This makes it\npossible to run scollector correctly with zero configuration or command line\nflags.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support. Ensure\nthat is in use if not using the OpenTSDB docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nExternal collectors are executables that scollector invokes, collects output\nfrom, and uses that like other collector data. The -c option specfies the\nexternal collectors directory. It should contain numbered directories like\nOpenTSDB tcollector expects. Any executable file in those directories is run\nevery N seconds, where N is the name of the directory. Use 0 for a program that\nshould be run continuously and simply pass data through to OpenTSDB (the program\nwill be restarted if it exits). Data output format is:\n\n\tmetric timestamp value tag1=val1 tag2=val2 ...\n\nTimestamp is in Unix format (seconds since epoch). Tags are optional. A host tag\nis automatically added, but overridden if specified. Stderr output is passed to\nscollector's log.\n\nConfiguration File\n\nIf scollector.conf exists in the same directory as the scollector executable or\nis specified via the -conf=\"\" flag, it's content will be used to set\nconfiguration flags. Configuration file values overwrite command line flags.\nThe configuration file is of the form key = value, one per line. Supported keys\nare: host (-h), hostname (-hostname), filter (-f), coldir (-c),\nsnmp (-s), icmp (-i), vsphere (-v). Example:\n\n\thost = other-tsdb:1234\n\tfilter = snmp\n\tsnmp = com@theswitch\n\nThere also are additional values that are used to configure specific collectors.\n\n\t\/\/ Linux processes to monitor use the form \"command,name,command line regex\"\n\tprocess = ruby,puppet-agent,puppet\n\tprocess = java,opentsdb,opentsdb\n\tprocess = java,elastic,elasticsearch\n\tprocess = java,logstash,logstash\n\tprocess = \/opt\/bosun\/bosun,bosun,\n\tprocess = \/opt\/scollector\/scollector,scollector,\n\n\t\/\/ Windows processes and service monitors use the form \"name regex\"\n\tprocess = ^chrome\n\tprocess = ^powershell\n\tprocess = ^scollector\n\tprocess = ^WinRM\n\tprocess = (?i)^MSSQLServer \/\/Matches are case sensitive unless specified\n\n\t\/\/ Dotnet processes to monitor use the form \"process\/service name regex\"\n\tprocess_dotnet=^w3wp \/\/Optional, as IIS processes are always monitored\n\tprocess_dotnet=^MyCustomService\n\tprocess_dotnet=^powershell\n\nWindows\n\nscollector has full Windows support. It can be run standalone, or installed as a\nservice (see -winsvc). The Event Log is used when installed as a service.\n\nSNMP\n\nBy default, scollector will collect data from the current host and report it to\nthe TSDB server. scollector has an SNMP mode where it also polls a given host:\n\n\tscollector -s community@host[,community@host...]\n\nPoll frequency currently defaults to 5 minutes. Some common OIDs regarding\ninterfaces are collected. Others can be added easily.\n\n*\/\npackage main\n<|endoftext|>"}

{"text":"<commit_before>\/*\n\nScollector is a metric collection agent for OpenTSDB 2.0 and Bosun.\n\ntcollector (https:\/\/github.com\/OpenTSDB\/tcollector) is OpenTSDB's data\ncollection framework built for OpenTSDB 1.0. scollector aims to be tcollector\nfor OpenTSDB 2.0 and is one method of sending data to Bosun (http:\/\/bosun.org\/)\nfor monitoring.\n\nUnlike tcollector, scollector is a single binary where all collectors are\ncompiled into scollector itself. scollector supports external collectors, but\nyour goal should be to use those temporarily until the go version is written or\nthe target system send data directly to OpenTSDB or Bosun. scollector has\nnative collectors for Linux, Darwin, and Windows and can pull data from other\nsystems such as AWS, SNMP, and vSphere.\n\nUsage:\n\tscollector [flag]\n\nThe flags are:\n\n\t-h=\"\"\n\t\tOpenTSDB or Bosun host. Overrides Host in conf file.\n\t-f=\"\"\n\t\tFilters collectors matching these terms, separated by\n\t\tcomma. Overrides Filter in conf file.\n\t-b=0\n\t\tOpenTSDB batch size. Default is 500.\n\t-conf=\"\"\n\t\tLocation of configuration file. Defaults to scollector.toml in directory of\n\t\tthe scollector executable.\n\t-l\n\t\tList available collectors (after Filter is applied).\n\t-m\n\t\tDisable sending of metadata.\n\t-version\n\t\tPrints the version and exits.\n\nAdditional flags on Windows:\n\t-winsvc=\"\"\n\t\tWindows Service management; can be: install, remove, start, stop\n\nDebug flags:\n\t-d\n\t\tenables debug output\n\t-p\n\t\tprint to screen instead of sending to a host\n\t-fake=0\n\t\tgenerates X fake data points per second on the test.fake metric\n\nThe only required paremeter is the host, which may be specified in the conf\nfile or with -h.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support. Ensure\nthat is in use if not using the OpenTSDB docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nExternal collectors are executables that scollector invokes, collects output\nfrom, and uses that like other collector data. The -c option specfies the\nexternal collectors directory. It should contain numbered directories like\nOpenTSDB tcollector expects. Any executable file in those directories is run\nevery N seconds, where N is the name of the directory. Use 0 for a program that\nshould be run continuously and simply pass data through to OpenTSDB (the program\nwill be restarted if it exits). Data output format is:\n\n\tmetric timestamp value tag1=val1 tag2=val2 ...\n\nTimestamp is in Unix format (seconds since epoch). Tags are optional. A host tag\nis automatically added, but overridden if specified. Stderr output is passed to\nscollector's log.\n\nConfiguration File\n\nIf scollector.toml exists in the same directory as the scollector\nexecutable or is specified via the -conf=\"\" flag, it's content\nwill be used to set configuration flags. The format is toml\n(https:\/\/github.com\/toml-lang\/toml\/blob\/master\/versions\/en\/toml-v0.2.0.md).\nAvailable keys are:\n\nHost (string): the OpenTSDB or Bosun host to send data, supports TLS and\nHTTP Basic Auth.\n\n\tHost = \"https:\/\/user:password@example.com\/\"\n\nFullHost (boolean): enables full hostnames: doesn't truncate to first \".\".\n\nColDir (string): is the external collectors directory.\n\nTags (table of strings): are added to every datapoint. If a collector specifies\nthe same tag key, this one will be overwritten. The host tag is not supported.\n\nHostname (string): overrides the system hostname.\n\nDisableSelf (boolean): disables sending of scollector self metrics.\n\nFreq (integer): is the default frequency in seconds for most collectors.\n\nBatchSize (integer): is the number of metrics that will be sent in each batch.\nDefault is 500.\n\nFilter (array of string): filters collectors matching these terms.\n\nPProf (string): optional IP:Port binding to be used for debugging with pprof.\nExamples: localhost:6060 for loopback or :6060 for all IP addresses.\n\nCollector configuration keys\n\nFollowing are configurations for collectors that do not autodetect.\n\nKeepalivedCommunity (string): if not empty, enables the Keepalived collector\nwith the specified community.\n\n\tKeepalivedCommunity = \"keepalivedcom\"\n\nHAProxy (array of table, keys are User, Password, Instances): HAProxy instances\nto poll.

Overrides Host in conf file.\n\t-f=\"\"\n\t\tFilters collectors matching these terms, separated by\n\t\tcomma. Overrides Filter in conf file.\n\t-b=0\n\t\tOpenTSDB batch size. Default is 500.\n\t-conf=\"\"\n\t\tLocation of configuration file. Defaults to scollector.toml in directory of\n\t\tthe scollector executable.\n\t-l\n\t\tList available collectors (after Filter is applied).\n\t-m\n\t\tDisable sending of metadata.\n\t-version\n\t\tPrints the version and exits.\n\nAdditional flags on Windows:\n\t-winsvc=\"\"\n\t\tWindows Service management; can be: install, remove, start, stop\n\nDebug flags:\n\t-d\n\t\tenables debug output\n\t-p\n\t\tprint to screen instead of sending to a host\n\t-fake=0\n\t\tgenerates X fake data points per second on the test.fake metric\n\nThe only required paremeter is the host, which may be specified in the conf\nfile or with -h.\n\nWarning\n\nscollector has not been tested outside of the Stack Exchange environment, and\nthus may act incorrectly elsewhere.\n\nscollector requires the new HTTP API of OpenTSDB 2.1 with gzip support. Ensure\nthat is in use if not using the OpenTSDB docker image.\n\nLogs\n\nIf started with -p or -d, scollector logs to Stdout. Otherwise, on Unixes,\nscollector logs to syslog. On Windows when started as a service, the Event Log\nis used.\n\nExternal Collectors\n\nExternal collectors are executables that scollector invokes, collects output\nfrom, and uses that like other collector data. The -c option specfies the\nexternal collectors directory. It should contain numbered directories like\nOpenTSDB tcollector expects. Any executable file in those directories is run\nevery N seconds, where N is the name of the directory. Use 0 for a program that\nshould be run continuously and simply pass data through to OpenTSDB (the program\nwill be restarted if it exits). Data output format is:\n\n\tmetric timestamp value tag1=val1 tag2=val2 ...\n\nTimestamp is in Unix format (seconds since epoch). Tags are optional. A host tag\nis automatically added, but overridden if specified. Stderr output is passed to\nscollector's log.\n\nConfiguration File\n\nIf scollector.toml exists in the same directory as the scollector\nexecutable or is specified via the -conf=\"\" flag, it's content\nwill be used to set configuration flags. The format is toml\n(https:\/\/github.com\/toml-lang\/toml\/blob\/master\/versions\/en\/toml-v0.2.0.md).\nAvailable keys are:\n\nHost (string): the OpenTSDB or Bosun host to send data, supports TLS and\nHTTP Basic Auth.\n\n\tHost = \"https:\/\/user:password@example.com\/\"\n\nFullHost (boolean): enables full hostnames: doesn't truncate to first \".\".\n\nColDir (string): is the external collectors directory.\n\nTags (table of strings): are added to every datapoint. If a collector specifies\nthe same tag key, this one will be overwritten. The host tag is not supported.\n\nHostname (string): overrides the system hostname.\n\nDisableSelf (boolean): disables sending of scollector self metrics.\n\nFreq (integer): is the default frequency in seconds for most collectors.\n\nBatchSize (integer): is the number of metrics that will be sent in each batch.\nDefault is 500.\n\nFilter (array of string): filters collectors matching these terms.\n\nPProf (string): optional IP:Port binding to be used for debugging with pprof.\nExamples: localhost:6060 for loopback or :6060 for all IP addresses.\n\nCollector configuration keys\n\nFollowing are configurations for collectors that do not autodetect.\n\nKeepalivedCommunity (string): if not empty, enables the Keepalived collector\nwith the specified community.\n\n\tKeepalivedCommunity = \"keepalivedcom\"\n\nHAProxy (array of table, keys are User, Password, Instances): HAProxy instances\nto poll.

Best practice for this value is to set it to your scrape interval\n\tAntiAffinity time.Duration `yaml:\"anti_affinity,omitempty\"`\n\n\t\/\/ IgnoreError will hide all errors from this given servergroup effectively making\n\t\/\/ the responses from this servergroup \"not required\" for the result.\n\t\/\/ Note: this allows you to make the tradeoff between availability of queries and consistency of results\n\tIgnoreError bool `yaml:\"ignore_error\"`\n\n\t\/\/ RelativeTimeRangeConfig defines a relative time range that this servergroup will respond to\n\t\/\/ An example use-case would be if a specific servergroup was long-term storage, it might only\n\t\/\/ have data 3d old and retain 90d of data.\n\t*RelativeTimeRangeConfig `yaml:\"relative_time_range\"`\n\n\t\/\/ AbsoluteTimeRangeConfig defines an absolute time range that this servergroup will respond to\n\t\/\/ An example use-case would be if a specific servergroup was was \"deprecated\" and wasn't getting\n\t\/\/ any new data after a specific given point in time\n\t*AbsoluteTimeRangeConfig `yaml:\"absolute_time_range\"`\n}\n\n\/\/ GetScheme returns the scheme for this servergroup\nfunc (c *Config) GetScheme() string {\n\treturn c.Scheme\n}\n\n\/\/ GetAntiAffinity returns the AntiAffinity time for this servergroup\nfunc (c *Config) GetAntiAffinity() model.Time {\n\treturn model.TimeFromUnix(int64((c.AntiAffinity).Seconds()))\n}\n\n\/\/ UnmarshalYAML implements the yaml.Unmarshaler interface.\nfunc (c *Config) UnmarshalYAML(unmarshal func(interface{}) error) error {\n\t*c = DefaultConfig\n\t\/\/ We want to set c to the defaults and then overwrite it with the input.\n\t\/\/ To make unmarshal fill the plain data struct rather than calling UnmarshalYAML\n\t\/\/ again, we have to hide it using a type indirection.\n\ttype plain Config\n\treturn unmarshal((*plain)(c))\n}\n\n\/\/ HTTPClientConfig extends prometheus' HTTPClientConfig\ntype HTTPClientConfig struct {\n\tDialTimeout time.Duration                `yaml:\"dial_timeout\"`\n\tHTTPConfig  config_util.HTTPClientConfig `yaml:\",inline\"`\n}\n\n\/\/ RelativeTimeRangeConfig configures durations relative from \"now\" to define\n\/\/ a servergroup's time range\ntype RelativeTimeRangeConfig struct {\n\tStart *time.Duration `yaml:\"start\"`\n\tEnd   *time.Duration `yaml:\"end\"`\n}\n\n\/\/ UnmarshalYAML implements the yaml.Unmarshaler interface.\nfunc (tr *RelativeTimeRangeConfig) UnmarshalYAML(unmarshal func(interface{}) error) error {\n\ttype plain RelativeTimeRangeConfig\n\tif err := unmarshal((*plain)(tr)); err != nil {\n\t\treturn err\n\t}\n\n\treturn tr.validate()\n}\n\nfunc (tr *RelativeTimeRangeConfig) validate() error {\n\tif tr.End != nil && tr.Start != nil && *tr.End < *tr.Start {\n\t\treturn fmt.Errorf(\"RelativeTimeRangeConfig: End must be after start\")\n\t}\n\treturn nil\n}\n\n\/\/ AbsoluteTimeRangeConfig contains absolute times to define a servergroup's time range\ntype AbsoluteTimeRangeConfig struct {\n\tStart time.Time `yaml:\"start\"`\n\tEnd   time.Time `yaml:\"end\"`\n}\n\n\/\/ UnmarshalYAML implements the yaml.Unmarshaler interface.\nfunc (tr *AbsoluteTimeRangeConfig) UnmarshalYAML(unmarshal func(interface{}) error) error {\n\ttype plain AbsoluteTimeRangeConfig\n\tif err := unmarshal((*plain)(tr)); err != nil {\n\t\treturn err\n\t}\n\n\treturn tr.validate()\n}\n\nfunc (tr *AbsoluteTimeRangeConfig) validate() error {\n\tif !tr.Start.IsZero() && !tr.End.IsZero() && tr.End.Before(tr.Start) {\n\t\treturn fmt.Errorf(\"AbsoluteTimeRangeConfig: End must be after start\")\n\t}\n\treturn nil\n}\n<|endoftext|>"}

A long term fix is to stop combining routes from two different configuration sources.\n\t\tif route.CatchAll() && len(routes) > 1 {\n\t\t\tcontinue\n\t\t}\n\n\t\t\/\/ enable mixer check on the route\n\t\tif mesh.MixerAddress != \"\" {\n\t\t\troute.OpaqueConfig = buildMixerOpaqueConfig(!mesh.DisablePolicyChecks, true, service.Hostname)\n\t\t}\n\n\t\tif applied := route.CombinePathPrefix(ingressRoute.Path, ingressRoute.Prefix); applied != nil {\n\t\t\tout = append(out, applied)\n\t\t}\n\t}\n\n\treturn out, tls, nil\n}\n\n\/\/ extractPort extracts the destination service port from the given destination,\nfunc extractPort(svc *model.Service, ingress *routing.IngressRule) (*model.Port, error) {\n\tswitch p := ingress.GetDestinationServicePort().(type) {\n\tcase *routing.IngressRule_DestinationPort:\n\t\tnum := p.DestinationPort\n\t\tport, exists := svc.Ports.GetByPort(int(num))\n\t\tif !exists {\n\t\t\treturn nil, fmt.Errorf(\"cannot find port %d in %q\", num, svc.Hostname)\n\t\t}\n\t\treturn port, nil\n\tcase *routing.IngressRule_DestinationPortName:\n\t\tname := p.DestinationPortName\n\t\tport, exists := svc.Ports.Get(name)\n\t\tif !exists {\n\t\t\treturn nil, fmt.Errorf(\"cannot find port %q in %q\", name, svc.Hostname)\n\t\t}\n\t\treturn port, nil\n\t}\n\treturn nil, errors.New(\"unrecognized destination port\")\n}\n<|endoftext|>"}

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\/*\nGit-codereview manages the code review process for Git changes using a Gerrit\nserver.\n\nThe git-codereview tool manages ``change branches'' in the local git repository.\nEach such branch tracks a single commit, or ``pending change,''\nthat is reviewed using a Gerrit server; the Gerrit remote must be\nnamed ``origin'' in the local git repo.\n\nModifications to the pending change are applied by amending the commit.\nThis process implements the ``single-commit feature branch'' model.\nCreating multiple-commit feature branches, for example to break a large\nchange into a reviewable sequence, is also supported; see the discussion below.\n\nOnce installed as git-codereview, the tool's commands are available through git\neither by running\n\n\tgit codereview <command>\n\nor, if aliases are installed, as\n\n\tgit <command>\n\nThe review tool's command names do not conflict with any extant git commands.\nThis document uses the first form for clarity but most users install these\naliases in their .gitconfig file:\n\n\t[alias]\n\t\tchange = codereview change\n\t\tgofmt = codereview gofmt\n\t\tmail = codereview mail\n\t\tpending = codereview pending\n\t\trebase-work = codereview rebase-work\n\t\tsubmit = codereview submit\n\t\tsync = codereview sync\n\nSingle-Commit Work Branches\n\nFor simple, unrelated changes, the typical usage of the git-codereview tool\nis to place each pending change in its own Git branch.\nIn this workflow, the work branch contains\neither no pending change beyond origin\/master (when there's no local work)\nor exactly one pending change beyond origin\/master (the change being developed).\n\nWhen there is no pending change on the work branch,\n``git codereview change'' creates one by running ``git commit.''\nOtherwise, when there is already a pending change,\n``git codereview change'' revises it by running ``git commit --amend.''\n\nThe ``git codereview mail'' and ``git codereview submit'' commands\nimplicitly operate on the lone pending change.\n\nMultiple-Commit Work Branches\n\nOf course, it is not always feasible to put each pending change in a separate branch.\nA sequence of changes that build on one another is more easily\nmanaged as multiple commits on a single branch, and the git-codereview tool\nsupports this workflow as well.\nTo add a new pending change, invoke ``git commit'' directly,\ninstead of ``git codereview change''.\nThe git-codereview tool adjusts its behavior when there are\nmultiple pending changes.\n\nThe ``git codereview change'' command amends the top commit in the stack (HEAD).\nTo amend a commit further down the stack, use Git's rebase support,\nfor example by using ``git commit --fixup'' followed by ``git codereview rebase-work.''\n\nThe ``git codereview mail'' command requires an explicit revision argument,\nbut note that since ``git codereview mail'' is implemented as a ``git push,''\nany commits earlier in the stack are necessarily also mailed.\n\nThe ``git codereview submit'' command also requires an explicit revision argument,\nand while earlier commits are necessarily still uploaded and mailed,\nonly the named revision or revisions are submitted (merged into origin\/master).\nIn a single-commit work branch, a successful ``git codereview submit''\neffectively runs ``git codereview sync'' automatically.\nIn a multiple-commit work branch, it does not, because\nthe implied ``git rebase'' may conflict with the remaining pending commits.\nInstead it is necessary to run ``git codereview sync'' explicitly\n(when ready) after ``git codereview submit.''\n\nReusing Work Branches\n\nAlthough one common practice is to create a new branch for each pending change,\nrunning ``git codereview submit'' (and possibly ``git codereview sync'')\nleaves the current branch ready for reuse with a future change.\nSome developers find it helpful to create a single work branch\n(``git change work'') and then do all work in that branch,\npossibly in the multiple-commit mode, never changing between branches.\n\nCommand Details\n\nAll commands accept these global flags:\n\nThe -v flag prints all commands that make changes. Multiple occurrences\ntrigger more verbosity in some commands, including sync.\n\nThe -n flag prints all commands that would be run, but does not run them.\n\nDescriptions of each command follow.\n\nBranchpoint\n\n\tgit codereview branchpoint\n\nThe branchpoint command prints the commit hash of the most recent commit\non the current branch that is shared with the Gerrit server. This is the point\nwhere local work branched from the published tree. The command is intended\nmainly for use in scripts. For example, ``git diff $(git codereview branchpoint)''\nor ``git log $(git codereview branchpoint)..HEAD''.\n\nChange\n\nThe change command creates and moves between Git branches and maintains the\npending changes on work branches.\n\n\tgit codereview change [-a] [-q] [branchname]\n\nGiven a branch name as an argument, the change command switches to the named\nbranch, creating it if necessary. If the branch is created and there are staged\nchanges, it will commit the changes to the branch, creating a new pending\nchange.\n\nWith no argument, the change command creates a new pending change from the\nstaged changes in the current branch or, if there is already a pending change,\namends that change.\n\nThe -q option skips the editing of an extant pending change's commit message.\n\nThe -a option automatically adds any unstaged edits in tracked files during\ncommit; it is equivalent to the 'git commit' -a option.\n\nGofmt\n\nThe gofmt command applies the gofmt program to all files modified in the\ncurrent work branch, both in the staging area (index) and the working tree\n(local directory).\n\n\tgit codereview gofmt [-l]\n\nThe -l option causes the command to list the files that need reformatting but\nnot reformat them. Otherwise, the gofmt command reformats modified files in\nplace. That is, files in the staging area are reformatted in the staging area,\nand files in the working tree are reformatted in the working tree.\n\nHelp\n\nThe help command displays basic usage instructions.\n\n\tgit codereview help\n\nHooks\n\nThe hooks command installs the Git hooks to enforce code review conventions.\n\n\tgit codereview hooks\n\nThe pre-commit hook checks that all Go code is formatted with gofmt and that\nthe commit is not being made directly to the master branch.\n\nThe commit-msg hook adds the Gerrit ``Change-Id'' line to the commit message if\nnot present. It also checks that the message uses the convention established by\nthe Go project that the first line has the form, pkg\/path: summary.\n\nThe hooks command will not overwrite an existing hook.\nIf it is not installing hooks, use ``git codereview hooks -v'' for details.\nThis hook installation is also done at startup by all other git codereview\ncommands, except ``git codereview help''.\n\nHook-Invoke\n\nThe hook-invoke command is an internal command that invokes the named Git hook.\n\n\tgit codereview hook-invoke <hook> [args]\n\nIt is run by the shell scripts installed by the ``git codereview hooks'' command.\n\nMail\n\nThe mail command starts the code review process for the pending change.\n\n\tgit codereview mail [-f] [-r email] [-cc email] [-trybot] [revision]\n\nIt pushes the pending change commit in the current branch to the Gerrit code\nreview server and prints the URL for the change on the server.\nIf the change already exists on the server, the mail command updates that\nchange with a new changeset.\n\nThe -r and -cc flags identify the email addresses of people to do the code\nreview and to be CC'ed about the code review.\nMultiple addresses are given as a comma-separated list.\n\nAn email address passed to -r or -cc can be shortened from name@domain to name.\nThe mail command resolves such shortenings by reading the list of past reviewers\nfrom the git repository log to find email addresses of the form name@somedomain\nand then, in case of ambiguity, using the reviewer who appears most often.\n\nThe -trybot flag runs the trybots on all new or updated changes. It is\nequivalent to setting the Run-Trybot+1 label from Gerrit.\n\nThe mail command fails if there are staged edits that are not committed.\nThe -f flag overrides this behavior.\n\nThe mail command updates the tag <branchname>.mailed to refer to the\ncommit that was most recently mailed, so running ``git diff <branchname>.mailed''\nshows diffs between what is on the Gerrit server and the current directory.\n\nIf there are multiple pending commits, the revision argument is mandatory.\nIf no revision is specified, the mail command prints a short summary of\nthe pending commits for use in deciding which to mail.\n\nIf any commit that would be pushed to the server contains the text\n\"DO NOT MAIL\" (case insensitive) in its commit message, the mail command\nwill refuse to send the commit to the server.\n\nPending\n\nThe pending command prints to standard output the status of all pending changes\nand staged, unstaged, and untracked files in the local repository.\n\n\tgit codereview pending [-c] [-l] [-s]\n\nThe -c flag causes the command to show pending changes only on the current branch.\n\nThe -l flag causes the command to use only locally available information.\nBy default, it fetches recent commits and code review information from the\nGerrit server.\n\nThe -s flag causes the command to print abbreviated (short) output.\n\nCommon shorter aliases include ``git p'' for ``git pending''\nand ``git pl'' for ``git pending -l'' (notably faster but without Gerrit information).\n\nRebase-work\n\nThe rebase-work command runs git rebase in interactive mode over pending changes.\nIt is shorthand for ``git rebase -i $(git codereview branchpoint)''.\nIt differs from plain ``git rebase -i'' in that the latter will try to incorporate\nnew commits from the origin branch during the rebase;\n``git codereview rebase-work'' does not.\n\nIn multiple-commit workflows, rebase-work is used so often\nthat it can be helpful to alias it to ``git rw''.\n\nSubmit\n\nThe submit command pushes the pending change to the Gerrit server and tells\nGerrit to submit it to the master branch.\n\n\tgit codereview submit [-i | revision...]\n\nThe command fails if there are modified files (staged or unstaged) that are not\npart of the pending change.\n\nThe -i option causes the submit command to open a list of commits to submit\nin the configured text editor, similar to ``git rebase -i''.\n\nIf multiple revisions are specified, the submit command submits each one in turn,\nstopping at the first failure.\n\nWhen run in a multiple-commit work branch,\neither the -i option or the revision argument is mandatory.\nIf both are omitted, the submit command prints a short summary of\nthe pending commits for use in deciding which to submit.\n\nAfter submitting the pending changes, the submit command tries to synchronize the\ncurrent branch to the submitted commit, if it can do so cleanly.\nIf not, it will prompt the user to run ``git codereview sync'' manually.\n\nAfter a successful sync, the branch can be used to prepare a new change.\n\nSync\n\nThe sync command updates the local repository.\n\n\tgit codereview sync\n\nIt fetches commits from the remote repository and merges them from the\nupstream branch to the current branch, rebasing any pending changes.\n\nConfiguration\n\nIf a file named codereview.cfg is present in the repository root,\ngit-codereview will use it for configuration. It should contain lines\nof this format:\n\n\tkey: value\n\nThe ``gerrit'' key sets the Gerrit URL for this project. Git-codereview\nautomatically derives the Gerrit URL from repositories hosted in\n*.googlesource.com.

Multiple occurrences\ntrigger more verbosity in some commands, including sync.\n\nThe -n flag prints all commands that would be run, but does not run them.\n\nDescriptions of each command follow.\n\nBranchpoint\n\n\tgit codereview branchpoint\n\nThe branchpoint command prints the commit hash of the most recent commit\non the current branch that is shared with the Gerrit server. This is the point\nwhere local work branched from the published tree. The command is intended\nmainly for use in scripts. For example, ``git diff $(git codereview branchpoint)''\nor ``git log $(git codereview branchpoint)..HEAD''.\n\nChange\n\nThe change command creates and moves between Git branches and maintains the\npending changes on work branches.\n\n\tgit codereview change [-a] [-q] [branchname]\n\nGiven a branch name as an argument, the change command switches to the named\nbranch, creating it if necessary. If the branch is created and there are staged\nchanges, it will commit the changes to the branch, creating a new pending\nchange.\n\nWith no argument, the change command creates a new pending change from the\nstaged changes in the current branch or, if there is already a pending change,\namends that change.\n\nThe -q option skips the editing of an extant pending change's commit message.\n\nThe -a option automatically adds any unstaged edits in tracked files during\ncommit; it is equivalent to the 'git commit' -a option.\n\nGofmt\n\nThe gofmt command applies the gofmt program to all files modified in the\ncurrent work branch, both in the staging area (index) and the working tree\n(local directory).\n\n\tgit codereview gofmt [-l]\n\nThe -l option causes the command to list the files that need reformatting but\nnot reformat them. Otherwise, the gofmt command reformats modified files in\nplace. That is, files in the staging area are reformatted in the staging area,\nand files in the working tree are reformatted in the working tree.\n\nHelp\n\nThe help command displays basic usage instructions.\n\n\tgit codereview help\n\nHooks\n\nThe hooks command installs the Git hooks to enforce code review conventions.\n\n\tgit codereview hooks\n\nThe pre-commit hook checks that all Go code is formatted with gofmt and that\nthe commit is not being made directly to the master branch.\n\nThe commit-msg hook adds the Gerrit ``Change-Id'' line to the commit message if\nnot present. It also checks that the message uses the convention established by\nthe Go project that the first line has the form, pkg\/path: summary.\n\nThe hooks command will not overwrite an existing hook.\nIf it is not installing hooks, use ``git codereview hooks -v'' for details.\nThis hook installation is also done at startup by all other git codereview\ncommands, except ``git codereview help''.\n\nHook-Invoke\n\nThe hook-invoke command is an internal command that invokes the named Git hook.\n\n\tgit codereview hook-invoke <hook> [args]\n\nIt is run by the shell scripts installed by the ``git codereview hooks'' command.\n\nMail\n\nThe mail command starts the code review process for the pending change.\n\n\tgit codereview mail [-f] [-r email] [-cc email] [-trybot] [revision]\n\nIt pushes the pending change commit in the current branch to the Gerrit code\nreview server and prints the URL for the change on the server.\nIf the change already exists on the server, the mail command updates that\nchange with a new changeset.\n\nThe -r and -cc flags identify the email addresses of people to do the code\nreview and to be CC'ed about the code review.\nMultiple addresses are given as a comma-separated list.\n\nAn email address passed to -r or -cc can be shortened from name@domain to name.\nThe mail command resolves such shortenings by reading the list of past reviewers\nfrom the git repository log to find email addresses of the form name@somedomain\nand then, in case of ambiguity, using the reviewer who appears most often.\n\nThe -trybot flag runs the trybots on all new or updated changes. It is\nequivalent to setting the Run-Trybot+1 label from Gerrit.\n\nThe mail command fails if there are staged edits that are not committed.\nThe -f flag overrides this behavior.\n\nThe mail command updates the tag <branchname>.mailed to refer to the\ncommit that was most recently mailed, so running ``git diff <branchname>.mailed''\nshows diffs between what is on the Gerrit server and the current directory.\n\nIf there are multiple pending commits, the revision argument is mandatory.\nIf no revision is specified, the mail command prints a short summary of\nthe pending commits for use in deciding which to mail.\n\nIf any commit that would be pushed to the server contains the text\n\"DO NOT MAIL\" (case insensitive) in its commit message, the mail command\nwill refuse to send the commit to the server.\n\nPending\n\nThe pending command prints to standard output the status of all pending changes\nand staged, unstaged, and untracked files in the local repository.\n\n\tgit codereview pending [-c] [-l] [-s]\n\nThe -c flag causes the command to show pending changes only on the current branch.\n\nThe -l flag causes the command to use only locally available information.\nBy default, it fetches recent commits and code review information from the\nGerrit server.\n\nThe -s flag causes the command to print abbreviated (short) output.\n\nCommon shorter aliases include ``git p'' for ``git pending''\nand ``git pl'' for ``git pending -l'' (notably faster but without Gerrit information).\n\nRebase-work\n\nThe rebase-work command runs git rebase in interactive mode over pending changes.\nIt is shorthand for ``git rebase -i $(git codereview branchpoint)''.\nIt differs from plain ``git rebase -i'' in that the latter will try to incorporate\nnew commits from the origin branch during the rebase;\n``git codereview rebase-work'' does not.\n\nIn multiple-commit workflows, rebase-work is used so often\nthat it can be helpful to alias it to ``git rw''.\n\nSubmit\n\nThe submit command pushes the pending change to the Gerrit server and tells\nGerrit to submit it to the master branch.\n\n\tgit codereview submit [-i | revision...]\n\nThe command fails if there are modified files (staged or unstaged) that are not\npart of the pending change.\n\nThe -i option causes the submit command to open a list of commits to submit\nin the configured text editor, similar to ``git rebase -i''.\n\nIf multiple revisions are specified, the submit command submits each one in turn,\nstopping at the first failure.\n\nWhen run in a multiple-commit work branch,\neither the -i option or the revision argument is mandatory.\nIf both are omitted, the submit command prints a short summary of\nthe pending commits for use in deciding which to submit.\n\nAfter submitting the pending changes, the submit command tries to synchronize the\ncurrent branch to the submitted commit, if it can do so cleanly.\nIf not, it will prompt the user to run ``git codereview sync'' manually.\n\nAfter a successful sync, the branch can be used to prepare a new change.\n\nSync\n\nThe sync command updates the local repository.\n\n\tgit codereview sync\n\nIt fetches commits from the remote repository and merges them from the\nupstream branch to the current branch, rebasing any pending changes.\n\nConfiguration\n\nIf a file named codereview.cfg is present in the repository root,\ngit-codereview will use it for configuration. It should contain lines\nof this format:\n\n\tkey: value\n\nThe ``gerrit'' key sets the Gerrit URL for this project. Git-codereview\nautomatically derives the Gerrit URL from repositories hosted in\n*.googlesource.com. If not set or derived, the repository is assumed to\nnot have Gerrit, and certain features won't work.\n\nThe ``issuerepo'' key specifies the GitHub repository to use for issues, if\ndifferent from the source repository. If set to ``golang\/go'', for example,\nlines such as ``Fixes #123'' in a commit message will be rewritten to ``Fixes\ngolang\/go#123''.\n\n*\/\npackage main\n<|endoftext|>"}
