The scenario looks like this\n\/\/\n\/\/ 1. Add, Delete a namespace really fast, *before* the add is observed by the controller using the reflector.\n\/\/ 2. Add or Update a quota that matches the Add namespace\n\/\/ 3. The cache had the intermediate state for the namespace for some period of time.  This makes the quota update the mapping indicating a match.\n\/\/ 4. The ns Delete is compressed out and never delivered to the controller, so the improper match is never cleared.\n\/\/\n\/\/ This sounds pretty bad, however, we fail in the \"safe\" direction and the consequences are detectable.\n\/\/ When going from quota to namespace, you can get back a namespace that doesn't exist.  There are no resource in a non-existence\n\/\/ namespace, so you know to clear all referenced resources.  In addition, this add\/delete has to happen so fast\n\/\/ that it would be nearly impossible for any resources to be created.  If you do create resources, then we must be observing\n\/\/ their deletes.  When quota is replenished, we'll see that we need to clear any charges.\n\/\/\n\/\/ When going from namespace to quota, you can get back a quota that doesn't exist.  Since the cache is shared,\n\/\/ we know that a missing quota means that there isn't anything for us to bill against, so we can skip it.\n\/\/\n\/\/ If the mapping cache is wrong and a previously deleted quota or namespace is created, this controller\n\/\/ correctly adds the items back to the list and clears out all previous mappings.\n\/\/\n\/\/ In addition to those constraints, the timing threshold for actually hitting this problem is really tight.  It's\n\/\/ basically a script that is creating and deleting things as fast as it possibly can.

The scenario looks like this\n\/\/\n\/\/ 1. Add, Delete a namespace really fast, *before* the add is observed by the controller using the reflector.\n\/\/ 2. Add or Update a quota that matches the Add namespace\n\/\/ 3. The cache had the intermediate state for the namespace for some period of time.  This makes the quota update the mapping indicating a match.\n\/\/ 4. The ns Delete is compressed out and never delivered to the controller, so the improper match is never cleared.\n\/\/\n\/\/ This sounds pretty bad, however, we fail in the \"safe\" direction and the consequences are detectable.\n\/\/ When going from quota to namespace, you can get back a namespace that doesn't exist.  There are no resource in a non-existence\n\/\/ namespace, so you know to clear all referenced resources.  In addition, this add\/delete has to happen so fast\n\/\/ that it would be nearly impossible for any resources to be created.  If you do create resources, then we must be observing\n\/\/ their deletes.  When quota is replenished, we'll see that we need to clear any charges.\n\/\/\n\/\/ When going from namespace to quota, you can get back a quota that doesn't exist.  Since the cache is shared,\n\/\/ we know that a missing quota means that there isn't anything for us to bill against, so we can skip it.\n\/\/\n\/\/ If the mapping cache is wrong and a previously deleted quota or namespace is created, this controller\n\/\/ correctly adds the items back to the list and clears out all previous mappings.\n\/\/\n\/\/ In addition to those constraints, the timing threshold for actually hitting this problem is really tight.  It's\n\/\/ basically a script that is creating and deleting things as fast as it possibly can.

That threshold\n\/\/ should go up every time that a worker fails, to make sure that if you have\n\/\/ repeated failures, you keep pulling in the fresh workers instead of getting\n\/\/ stuck and always rejecting all the standby workers.\ntype unfinishedDownloadChunk struct {\n\t\/\/ Fetch + Write instructions - read only or otherwise thread safe.\n\tdestination downloadDestination \/\/ Where to write the recovered logical chunk.\n\terasureCode modules.ErasureCoder\n\tmasterKey   crypto.TwofishKey\n\n\t\/\/ Fetch + Write instructions - read only or otherwise thread safe.\n\tstaticChunkIndex  uint64                                     \/\/ Required for deriving the encryption keys for each piece.\n\tstaticCacheID     string                                     \/\/ Used to uniquely identify a chunk in the chunk cache.\n\tstaticChunkMap    map[types.FileContractID]downloadPieceInfo \/\/ Maps from file contract ids to the info for the piece associated with that contract\n\tstaticChunkSize   uint64\n\tstaticFetchLength uint64 \/\/ Length within the logical chunk to fetch.\n\tstaticFetchOffset uint64 \/\/ Offset within the logical chunk that is being downloaded.\n\tstaticPieceSize   uint64\n\tstaticWriteOffset int64 \/\/ Offet within the writer to write the completed data.\n\n\t\/\/ Fetch + Write instructions - read only or otherwise thread safe.\n\tstaticLatencyTarget time.Duration\n\tstaticNeedsMemory   bool \/\/ Set to true if memory was not pre-allocated for this chunk.\n\tstaticOverdrive     int\n\tstaticPriority      uint64\n\n\t\/\/ Download chunk state - need mutex to access.\n\tfailed            bool      \/\/ Indicates if the chunk has been marked as failed.\n\tphysicalChunkData [][]byte  \/\/ Used to recover the logical data.\n\tpieceUsage        []bool    \/\/ Which pieces are being actively fetched.\n\tpiecesCompleted   int       \/\/ Number of pieces that have successfully completed.\n\tpiecesRegistered  int       \/\/ Number of pieces that workers are actively fetching.\n\trecoveryComplete  bool      \/\/ Whether or not the recovery has completed and the chunk memory released.\n\tworkersRemaining  int       \/\/ Number of workers still able to fetch the chunk.\n\tworkersStandby    []*worker \/\/ Set of workers that are able to work on this download, but are not needed unless other workers fail.\n\n\t\/\/ Memory management variables.\n\tmemoryAllocated uint64\n\n\t\/\/ The download object, mostly to update download progress.\n\tdownload *download\n\tmu       sync.Mutex\n\n\t\/\/ Caching related fields\n\tchunkCache map[string]*cacheData\n\tcacheMu    *sync.Mutex\n}\n\n\/\/ fail will set the chunk status to failed.

To use\n\/\/ nested subcommands, the key in the Commands mapping below contains the\n\/\/ full subcommand. In this example, it would be \"foo bar\".\n\/\/\n\/\/ If you use a CLI with nested subcommands, some semantics change due to\n\/\/ ambiguities:\n\/\/\n\/\/   * We use longest prefix matching to find a matching subcommand. This\n\/\/     means if you register \"foo bar\" and the user executes \"cli foo qux\",\n\/\/     the \"foo\" commmand will be executed with the arg \"qux\". It is up to\n\/\/     you to handle these args. One option is to just return the special\n\/\/     help return code `RunResultHelp` to display help and exit.\n\/\/\n\/\/   * The help flag \"-h\" or \"-help\" will look at all args to determine\n\/\/     the help function. For example: \"otto apps list -h\" will show the\n\/\/     help for \"apps list\" but \"otto apps -h\" will show it for \"apps\".\n\/\/     In the normal CLI, only the first subcommand is used.\n\/\/\n\/\/   * The help flag will list any subcommands that a command takes\n\/\/     as well as the command's help itself. If there are no subcommands,\n\/\/     it will note this. If the CLI itself has no subcommands, this entire\n\/\/     section is omitted.\n\/\/\n\/\/   * Any parent commands that don't exist are automatically created as\n\/\/     no-op commands that just show help for other subcommands. For example,\n\/\/     if you only register \"foo bar\", then \"foo\" is automatically created.\n\/\/\ntype CLI struct {\n\t\/\/ Args is the list of command-line arguments received excluding\n\t\/\/ the name of the app. For example, if the command \".\/cli foo bar\"\n\t\/\/ was invoked, then Args should be []string{\"foo\", \"bar\"}.\n\tArgs []string\n\n\t\/\/ Commands is a mapping of subcommand names to a factory function\n\t\/\/ for creating that Command implementation. If there is a command\n\t\/\/ with a blank string \"\", then it will be used as the default command\n\t\/\/ if no subcommand is specified.\n\t\/\/\n\t\/\/ If the key has a space in it, this will create a nested subcommand.\n\t\/\/ For example, if the key is \"foo bar\", then to access it our CLI\n\t\/\/ must be accessed with \".\/cli foo bar\". See the docs for CLI for\n\t\/\/ notes on how this changes some other behavior of the CLI as well.\n\tCommands map[string]CommandFactory\n\n\t\/\/ Name defines the name of the CLI.\n\tName string\n\n\t\/\/ Version of the CLI.\n\tVersion string\n\n\t\/\/ HelpFunc and HelpWriter are used to output help information, if\n\t\/\/ requested.\n\t\/\/\n\t\/\/ HelpFunc is the function called to generate the generic help\n\t\/\/ text that is shown if help must be shown for the CLI that doesn't\n\t\/\/ pertain to a specific command.\n\t\/\/\n\t\/\/ HelpWriter is the Writer where the help text is outputted to.

To use\n\/\/ nested subcommands, the key in the Commands mapping below contains the\n\/\/ full subcommand. In this example, it would be \"foo bar\".\n\/\/\n\/\/ If you use a CLI with nested subcommands, some semantics change due to\n\/\/ ambiguities:\n\/\/\n\/\/   * We use longest prefix matching to find a matching subcommand. This\n\/\/     means if you register \"foo bar\" and the user executes \"cli foo qux\",\n\/\/     the \"foo\" commmand will be executed with the arg \"qux\". It is up to\n\/\/     you to handle these args. One option is to just return the special\n\/\/     help return code `RunResultHelp` to display help and exit.\n\/\/\n\/\/   * The help flag \"-h\" or \"-help\" will look at all args to determine\n\/\/     the help function. For example: \"otto apps list -h\" will show the\n\/\/     help for \"apps list\" but \"otto apps -h\" will show it for \"apps\".\n\/\/     In the normal CLI, only the first subcommand is used.\n\/\/\n\/\/   * The help flag will list any subcommands that a command takes\n\/\/     as well as the command's help itself. If there are no subcommands,\n\/\/     it will note this. If the CLI itself has no subcommands, this entire\n\/\/     section is omitted.\n\/\/\n\/\/   * Any parent commands that don't exist are automatically created as\n\/\/     no-op commands that just show help for other subcommands. For example,\n\/\/     if you only register \"foo bar\", then \"foo\" is automatically created.\n\/\/\ntype CLI struct {\n\t\/\/ Args is the list of command-line arguments received excluding\n\t\/\/ the name of the app. For example, if the command \".\/cli foo bar\"\n\t\/\/ was invoked, then Args should be []string{\"foo\", \"bar\"}.\n\tArgs []string\n\n\t\/\/ Commands is a mapping of subcommand names to a factory function\n\t\/\/ for creating that Command implementation. If there is a command\n\t\/\/ with a blank string \"\", then it will be used as the default command\n\t\/\/ if no subcommand is specified.\n\t\/\/\n\t\/\/ If the key has a space in it, this will create a nested subcommand.\n\t\/\/ For example, if the key is \"foo bar\", then to access it our CLI\n\t\/\/ must be accessed with \".\/cli foo bar\". See the docs for CLI for\n\t\/\/ notes on how this changes some other behavior of the CLI as well.\n\tCommands map[string]CommandFactory\n\n\t\/\/ Name defines the name of the CLI.\n\tName string\n\n\t\/\/ Version of the CLI.\n\tVersion string\n\n\t\/\/ HelpFunc and HelpWriter are used to output help information, if\n\t\/\/ requested.\n\t\/\/\n\t\/\/ HelpFunc is the function called to generate the generic help\n\t\/\/ text that is shown if help must be shown for the CLI that doesn't\n\t\/\/ pertain to a specific command.\n\t\/\/\n\t\/\/ HelpWriter is the Writer where the help text is outputted to.

It is the layer that integrates an\n   external application component like Postgres or WordPress into juju. A juju\n   Service may generally be seen as the composition of its juju Charm and the\n   upstream application (traditionally made available through its package).\n\nCharm URL\n   A Charm URL is a resource locator for a charm, with the following format\n   and restrictions:\n\n       <schema>:[~<user>\/]<collection>\/<name>[-<revision>]\n\n   schema must be either \"cs\", for a charm from the Juju charm store, or\n   \"local\", for a charm from a local repository.\n\n   user is only valid in charm store URLs, and allows you to source charms\n   from individual users (rather than from the main charm store); it must be a\n   valid Launchpad user name.\n\n   collection denotes a charm's purpose and status, and is derived from the\n   Ubuntu series targeted by its contained charms: examples include \"precise\",\n   \"quantal\", \"oneiric-universe\".\n\n   name is just the name of the charm; it must start and end with lowercase\n   (ascii) letters, and can otherwise contain any combination of lowercase\n   letters, digits, and \"-\"s.\n\n   revision, if specified, points to a specific revision of the charm pointed\n   to by the rest of the URL. It must be a non-negative integer.\n\nEndpoint\n   The combination of a service name and a relation name.\n\nEnvironment\n   An Environment is a configured location where Services can be deployed\n   onto. An Environment typically has a name, which can usually be omitted\n   when there's a single Environment configured, or when a default is\n   explicitly defined. Depending on the type of Environment, it may have to be\n   bootstrapped before interactions with it may take place (e.g. EC2). The\n   local environment configuration is defined in the ~\/.juju\/environments.yaml\n   file.\n\nMachine Agent\n   Software which runs inside each machine that is part of an Environment, and\n   is able to handle the needs of deploying and managing Service Units in this\n   machine.\n\nProvisioning Agent\n   Software responsible for automatically allocating and terminating machines\n   in an Environment, as necessary for the requested configuration.\n\nRelation\n   Relations are the way in which juju enables Services to communicate to each\n   other, and the way in which the topology of Services is assembled. The\n   Charm defines which Relations a given Service may establish, and what kind\n   of interface these Relations require.\n\n   In many cases, the establishment of a Relation will result into an actual\n   TCP connection being created between the Service Units, but that's not\n   necessarily the case. Relations may also be established to inform Services\n   of configuration parameters, to request monitoring information, or any\n   other details which the Charm author has chosen to make available.\n\nRepository\n   A location where multiple charms are stored. Repositories may be as simple\n   as a directory structure on a local disk, or as complex as a rich smart\n   server supporting remote searching and so on.\n\nService\n   juju operates in terms of services. A service is any application (or set of\n   applications) that is integrated into the framework as an individual\n   component which should generally be joined with other components to perform\n   a more complex goal.\n\n   As an example, WordPress could be deployed as a service and, to perform its\n   tasks properly, might communicate with a database service and a load\n   balancer service.\n\nService Configuration\n   There are many different settings in a juju deployment, but the term\n   Service Configuration refers to the settings which a user can define to\n   customize the behavior of a Service.\n\n   The behavior of a Service when its Service Configuration changes is\n   entirely defined by its Charm.\n\nService Unit\n   A running instance of a given juju Service. Simple Services may be deployed\n   with a single Service Unit, but it is possible for an individual Service to\n   have multiple Service Units running in independent machines. All Service\n   Units for a given Service will share the same Charm, the same relations,\n   and the same user-provided configuration.\n\n   For instance, one may deploy a single MongoDB Service, and specify that it\n   should run 3 Units, so that the replica set is resilient to\n   failures. Internally, even though the replica set shares the same\n   user-provided configuration, each Unit may be performing different roles\n   within the replica set, as defined by the Charm.\n\nService Unit Agent\n   Software which manages all the lifecycle of a single Service Unit.\n\n`\n<commit_msg>Update the header block.<commit_after>\/\/ Copyright 2013 Canonical Ltd.\n\/\/ Licensed under the AGPLv3, see LICENCE file for details.\n\npackage main\n\nconst helpBasics = `\nJuju -- devops distilled\nhttps:\/\/juju.ubuntu.com\/\n\nJuju provides easy, intelligent service orchestration on top of environments\nsuch as OpenStack, Amazon AWS, bare metal, or your own local machine.\n\nBasic commands:\n  juju init             generate boilerplate configuration for juju environments\n  juju bootstrap        start up an environment from scratch\n\n  juju deploy           deploy a new service\n  juju add-relation     add a relation between two services\n  juju expose           expose a service\n\n  juju help bootstrap   more help on e.g. bootstrap command\n  juju help commands    list all commands\n  juju help glossary    glossary of terms\n  juju help topics      list all help topics\n\nProvider information:\n  juju help local       use on this computer\n  juju help aws         use on AWS\n  juju help openstack   use on OpenStack\n  juju help hpcloud     use on HP Cloud\n`\n\nconst helpLocalProvider = `\nFirst install Juju and some dependencies it needs.

After the initial bootstrap, you do not need 'sudo' anymore,\nexcept to 'sudo juju destroy-environment' when you want to tear everything\ndown.\n\nYou deploy charms from the charm store using the following commands:\n\n    juju deploy mysql\n    juju deploy wordpress\n    juju add-relation wordpress mysql\n\nReferences:\n\n - Source: Question on Ask Ubuntu [1]\n - [Documentation][2]\n\n  [1]: http:\/\/askubuntu.com\/questions\/65359\/how-do-i-configure-juju-for-local-usage\n  [2]: https:\/\/juju.ubuntu.com\/docs\/getting-started.html\n`\n\nconst helpOpenstackProvider = `\n\nFirst off you need juju and charm-tools, ensure you have the latest stable\njuju:\n\n    sudo add-apt-repository ppa:juju\/stable\n    sudo apt-get update && sudo apt-get install juju-core charm-tools\n\nDo a 'juju generate-config -w' to generate a config for OpenStack that you can\ncustomize for your needs.\n\nHere's an example OpenStack configuration for '~\/.juju\/environments.yaml',\nincluding the commented out sections:\n\n      openstack:\n        type: openstack\n        # Specifies whether the use of a floating IP address is required to\n        # give the nodes a public IP address.

It is the layer that integrates an\n   external application component like Postgres or WordPress into juju. A juju\n   Service may generally be seen as the composition of its juju Charm and the\n   upstream application (traditionally made available through its package).\n\nCharm URL\n   A Charm URL is a resource locator for a charm, with the following format\n   and restrictions:\n\n       <schema>:[~<user>\/]<collection>\/<name>[-<revision>]\n\n   schema must be either \"cs\", for a charm from the Juju charm store, or\n   \"local\", for a charm from a local repository.\n\n   user is only valid in charm store URLs, and allows you to source charms\n   from individual users (rather than from the main charm store); it must be a\n   valid Launchpad user name.\n\n   collection denotes a charm's purpose and status, and is derived from the\n   Ubuntu series targeted by its contained charms: examples include \"precise\",\n   \"quantal\", \"oneiric-universe\".\n\n   name is just the name of the charm; it must start and end with lowercase\n   (ascii) letters, and can otherwise contain any combination of lowercase\n   letters, digits, and \"-\"s.\n\n   revision, if specified, points to a specific revision of the charm pointed\n   to by the rest of the URL. It must be a non-negative integer.\n\nEndpoint\n   The combination of a service name and a relation name.\n\nEnvironment\n   An Environment is a configured location where Services can be deployed\n   onto. An Environment typically has a name, which can usually be omitted\n   when there's a single Environment configured, or when a default is\n   explicitly defined. Depending on the type of Environment, it may have to be\n   bootstrapped before interactions with it may take place (e.g. EC2). The\n   local environment configuration is defined in the ~\/.juju\/environments.yaml\n   file.\n\nMachine Agent\n   Software which runs inside each machine that is part of an Environment, and\n   is able to handle the needs of deploying and managing Service Units in this\n   machine.\n\nProvisioning Agent\n   Software responsible for automatically allocating and terminating machines\n   in an Environment, as necessary for the requested configuration.\n\nRelation\n   Relations are the way in which juju enables Services to communicate to each\n   other, and the way in which the topology of Services is assembled. The\n   Charm defines which Relations a given Service may establish, and what kind\n   of interface these Relations require.\n\n   In many cases, the establishment of a Relation will result into an actual\n   TCP connection being created between the Service Units, but that's not\n   necessarily the case. Relations may also be established to inform Services\n   of configuration parameters, to request monitoring information, or any\n   other details which the Charm author has chosen to make available.\n\nRepository\n   A location where multiple charms are stored. Repositories may be as simple\n   as a directory structure on a local disk, or as complex as a rich smart\n   server supporting remote searching and so on.\n\nService\n   juju operates in terms of services. A service is any application (or set of\n   applications) that is integrated into the framework as an individual\n   component which should generally be joined with other components to perform\n   a more complex goal.\n\n   As an example, WordPress could be deployed as a service and, to perform its\n   tasks properly, might communicate with a database service and a load\n   balancer service.\n\nService Configuration\n   There are many different settings in a juju deployment, but the term\n   Service Configuration refers to the settings which a user can define to\n   customize the behavior of a Service.\n\n   The behavior of a Service when its Service Configuration changes is\n   entirely defined by its Charm.\n\nService Unit\n   A running instance of a given juju Service. Simple Services may be deployed\n   with a single Service Unit, but it is possible for an individual Service to\n   have multiple Service Units running in independent machines. All Service\n   Units for a given Service will share the same Charm, the same relations,\n   and the same user-provided configuration.\n\n   For instance, one may deploy a single MongoDB Service, and specify that it\n   should run 3 Units, so that the replica set is resilient to\n   failures. Internally, even though the replica set shares the same\n   user-provided configuration, each Unit may be performing different roles\n   within the replica set, as defined by the Charm.\n\nService Unit Agent\n   Software which manages all the lifecycle of a single Service Unit.\n\n`\n<|endoftext|>"}

The\n\/\/ sqlite3 driver, for example, returns \"sqlite3.sourceid\" in\n\/\/ addition to \"version\" and \"driver\".\ntype VersionSignature func() (map[string]string, os.Error)\n\n\/\/ Database drivers must provide the Open() function to allow\n\/\/ clients to establish connections to a database system. The\n\/\/ parameter to Open() is a URL of the following form:\n\/\/\n\/\/\tdriver:\/\/username:password@host:port\/database?key=value;key=value\n\/\/\n\/\/ Most parts of this URL are optional.

The format of this line is subject to change.\n\tCurrently, it is:\n\t\tgc # @#s #%: #+#+# ms clock, #+#\/#\/#+# ms cpu, #->#-># MB, # MB goal, # P\n\twhere the fields are as follows:\n\t\tgc #        the GC number, incremented at each GC\n\t\t@#s         time in seconds since program start\n\t\t#%          percentage of time spent in GC since program start\n\t\t#+...+#     wall-clock\/CPU times for the phases of the GC\n\t\t#->#-># MB  heap size at GC start, at GC end, and live heap\n\t\t# MB goal   goal heap size\n\t\t# P         number of processors used\n\tThe phases are stop-the-world (STW) sweep termination, concurrent\n\tmark and scan, and STW mark termination.

Refer to the description of\n\tMemProfileRate for the default value.\n\n\tinvalidptr: defaults to invalidptr=1, causing the garbage collector and stack\n\tcopier to crash the program if an invalid pointer value (for example, 1)\n\tis found in a pointer-typed location. Setting invalidptr=0 disables this check.\n\tThis should only be used as a temporary workaround to diagnose buggy code.\n\tThe real fix is to not store integers in pointer-typed locations.\n\n\tsbrk: setting sbrk=1 replaces the memory allocator and garbage collector\n\twith a trivial allocator that obtains memory from the operating system and\n\tnever reclaims any memory.\n\n\tscavenge: scavenge=1 enables debugging mode of heap scavenger.\n\n\tscheddetail: setting schedtrace=X and scheddetail=1 causes the scheduler to emit\n\tdetailed multiline info every X milliseconds, describing state of the scheduler,\n\tprocessors, threads and goroutines.\n\n\tschedtrace: setting schedtrace=X causes the scheduler to emit a single line to standard\n\terror every X milliseconds, summarizing the scheduler state.\n\nThe net and net\/http packages also refer to debugging variables in GODEBUG.\nSee the documentation for those packages for details.\n\nThe GOMAXPROCS variable limits the number of operating system threads that\ncan execute user-level Go code simultaneously. There is no limit to the number of threads\nthat can be blocked in system calls on behalf of Go code; those do not count against\nthe GOMAXPROCS limit. This package's GOMAXPROCS function queries and changes\nthe limit.\n\nThe GOTRACEBACK variable controls the amount of output generated when a Go\nprogram fails due to an unrecovered panic or an unexpected runtime condition.\nBy default, a failure prints a stack trace for the current goroutine,\neliding functions internal to the run-time system, and then exits with exit code 2.\nThe failure prints stack traces for all goroutines if there is no current goroutine\nor the failure is internal to the run-time.\nGOTRACEBACK=none omits the goroutine stack traces entirely.\nGOTRACEBACK=single (the default) behaves as described above.\nGOTRACEBACK=all adds stack traces for all user-created goroutines.\nGOTRACEBACK=system is like ``all'' but adds stack frames for run-time functions\nand shows goroutines created internally by the run-time.\nGOTRACEBACK=crash is like ``system'' but crashes in an operating system-specific\nmanner instead of exiting. For example, on Unix systems, the crash raises\nSIGABRT to trigger a core dump.\nFor historical reasons, the GOTRACEBACK settings 0, 1, and 2 are synonyms for\nnone, all, and system, respectively.\nThe runtime\/debug package's SetTraceback function allows increasing the\namount of output at run time, but it cannot reduce the amount below that\nspecified by the environment variable.\nSee https:\/\/golang.org\/pkg\/runtime\/debug\/#SetTraceback.\n\nThe GOARCH, GOOS, GOPATH, and GOROOT environment variables complete\nthe set of Go environment variables.

The CPU times\n\tfor mark\/scan are broken down in to assist time (GC performed in\n\tline with allocation), background GC time, and idle GC time.\n\tIf the line ends with \"(forced)\", this GC was forced by a\n\truntime.GC() call and all phases are STW.\n\n\tSetting gctrace to any value > 0 also causes the garbage collector\n\tto emit a summary when memory is released back to the system.\n\tThis process of returning memory to the system is called scavenging.\n\tThe format of this summary is subject to change.\n\tCurrently it is:\n\t\tscvg#: # MB released  printed only if non-zero\n\t\tscvg#: inuse: # idle: # sys: # released: # consumed: # (MB)\n\twhere the fields are as follows:\n\t\tscvg#        the scavenge cycle number, incremented at each scavenge\n\t\tinuse: #     MB used or partially used spans\n\t\tidle: #      MB spans pending scavenging\n\t\tsys: #       MB mapped from the system\n\t\treleased: #  MB released to the system\n\t\tconsumed: #  MB allocated from the system\n\n\tmemprofilerate: setting memprofilerate=X will update the value of runtime.MemProfileRate.\n\tWhen set to 0 memory profiling is disabled.  Refer to the description of\n\tMemProfileRate for the default value.\n\n\tinvalidptr: defaults to invalidptr=1, causing the garbage collector and stack\n\tcopier to crash the program if an invalid pointer value (for example, 1)\n\tis found in a pointer-typed location. Setting invalidptr=0 disables this check.\n\tThis should only be used as a temporary workaround to diagnose buggy code.\n\tThe real fix is to not store integers in pointer-typed locations.\n\n\tsbrk: setting sbrk=1 replaces the memory allocator and garbage collector\n\twith a trivial allocator that obtains memory from the operating system and\n\tnever reclaims any memory.\n\n\tscavenge: scavenge=1 enables debugging mode of heap scavenger.\n\n\tscheddetail: setting schedtrace=X and scheddetail=1 causes the scheduler to emit\n\tdetailed multiline info every X milliseconds, describing state of the scheduler,\n\tprocessors, threads and goroutines.\n\n\tschedtrace: setting schedtrace=X causes the scheduler to emit a single line to standard\n\terror every X milliseconds, summarizing the scheduler state.\n\nThe net and net\/http packages also refer to debugging variables in GODEBUG.\nSee the documentation for those packages for details.\n\nThe GOMAXPROCS variable limits the number of operating system threads that\ncan execute user-level Go code simultaneously. There is no limit to the number of threads\nthat can be blocked in system calls on behalf of Go code; those do not count against\nthe GOMAXPROCS limit. This package's GOMAXPROCS function queries and changes\nthe limit.\n\nThe GOTRACEBACK variable controls the amount of output generated when a Go\nprogram fails due to an unrecovered panic or an unexpected runtime condition.\nBy default, a failure prints a stack trace for the current goroutine,\neliding functions internal to the run-time system, and then exits with exit code 2.\nThe failure prints stack traces for all goroutines if there is no current goroutine\nor the failure is internal to the run-time.\nGOTRACEBACK=none omits the goroutine stack traces entirely.\nGOTRACEBACK=single (the default) behaves as described above.\nGOTRACEBACK=all adds stack traces for all user-created goroutines.\nGOTRACEBACK=system is like ``all'' but adds stack frames for run-time functions\nand shows goroutines created internally by the run-time.\nGOTRACEBACK=crash is like ``system'' but crashes in an operating system-specific\nmanner instead of exiting. For example, on Unix systems, the crash raises\nSIGABRT to trigger a core dump.\nFor historical reasons, the GOTRACEBACK settings 0, 1, and 2 are synonyms for\nnone, all, and system, respectively.\nThe runtime\/debug package's SetTraceback function allows increasing the\namount of output at run time, but it cannot reduce the amount below that\nspecified by the environment variable.\nSee https:\/\/golang.org\/pkg\/runtime\/debug\/#SetTraceback.\n\nThe GOARCH, GOOS, GOPATH, and GOROOT environment variables complete\nthe set of Go environment variables. They influence the building of Go programs\n(see https:\/\/golang.org\/cmd\/go and https:\/\/golang.org\/pkg\/go\/build).\nGOARCH, GOOS, and GOROOT are recorded at compile time and made available by\nconstants or functions in this package, but they do not influence the execution\nof the run-time system.\n*\/\npackage runtime\n\nimport \"runtime\/internal\/sys\"\n\n\/\/ Caller reports file and line number information about function invocations on\n\/\/ the calling goroutine's stack.

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\/\/ Package websocket implements the WebSocket protocol defined in RFC 6455.\n\/\/\n\/\/ Overview\n\/\/\n\/\/ The Conn type represents a WebSocket connection. A server application calls\n\/\/ the Upgrader.Upgrade method from an HTTP request handler to get a *Conn:\n\/\/\n\/\/  var upgrader = websocket.Upgrader{\n\/\/      ReadBufferSize:  1024,\n\/\/      WriteBufferSize: 1024,\n\/\/  }\n\/\/\n\/\/  func handler(w http.ResponseWriter, r *http.Request) {\n\/\/      conn, err := upgrader.Upgrade(w, r, nil)\n\/\/      if err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/      ... Use conn to send and receive messages.\n\/\/  }\n\/\/\n\/\/ Call the connection's WriteMessage and ReadMessage methods to send and\n\/\/ receive messages as a slice of bytes. This snippet of code shows how to echo\n\/\/ messages using these methods:\n\/\/\n\/\/  for {\n\/\/      messageType, p, err := conn.ReadMessage()\n\/\/      if err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/      if err := conn.WriteMessage(messageType, p); err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/  }\n\/\/\n\/\/ In above snippet of code, p is a []byte and messageType is an int with value\n\/\/ websocket.BinaryMessage or websocket.TextMessage.\n\/\/\n\/\/ An application can also send and receive messages using the io.WriteCloser\n\/\/ and io.Reader interfaces. To send a message, call the connection NextWriter\n\/\/ method to get an io.WriteCloser, write the message to the writer and close\n\/\/ the writer when done. To receive a message, call the connection NextReader\n\/\/ method to get an io.Reader and read until io.EOF is returned. This snippet\n\/\/ shows how to echo messages using the NextWriter and NextReader methods:\n\/\/\n\/\/  for {\n\/\/      messageType, r, err := conn.NextReader()\n\/\/      if err != nil {\n\/\/          return\n\/\/      }\n\/\/      w, err := conn.NextWriter(messageType)\n\/\/      if err != nil {\n\/\/          return err\n\/\/      }\n\/\/      if _, err := io.Copy(w, r); err != nil {\n\/\/          return err\n\/\/      }\n\/\/      if err := w.Close(); err != nil {\n\/\/          return err\n\/\/      }\n\/\/  }\n\/\/\n\/\/ Data Messages\n\/\/\n\/\/ The WebSocket protocol distinguishes between text and binary data messages.\n\/\/ Text messages are interpreted as UTF-8 encoded text. The interpretation of\n\/\/ binary messages is left to the application.\n\/\/\n\/\/ This package uses the TextMessage and BinaryMessage integer constants to\n\/\/ identify the two data message types. The ReadMessage and NextReader methods\n\/\/ return the type of the received message. The messageType argument to the\n\/\/ WriteMessage and NextWriter methods specifies the type of a sent message.\n\/\/\n\/\/ It is the application's responsibility to ensure that text messages are\n\/\/ valid UTF-8 encoded text.\n\/\/\n\/\/ Control Messages\n\/\/\n\/\/ The WebSocket protocol defines three types of control messages: close, ping\n\/\/ and pong.

The default close\n\/\/ handler sends a close message to the peer.\n\/\/\n\/\/ Connections handle received ping messages by calling the handler function\n\/\/ set with the SetPingHandler method. The default ping handler sends a pong\n\/\/ message to the peer.\n\/\/\n\/\/ Connections handle received pong messages by calling the handler function\n\/\/ set with the SetPongHandler method. The default pong handler does nothing.\n\/\/ If an application sends ping messages, then the application should set a\n\/\/ pong handler to receive the corresponding pong.\n\/\/\n\/\/ The control message handler functions are called from the NextReader,\n\/\/ ReadMessage and message reader Read methods. The default close and ping\n\/\/ handlers can block these methods for a short time when the handler writes to\n\/\/ the connection.\n\/\/\n\/\/ The application must read the connection to process close, ping and pong\n\/\/ messages sent from the peer. If the application is not otherwise interested\n\/\/ in messages from the peer, then the application should start a goroutine to\n\/\/ read and discard messages from the peer. A simple example is:\n\/\/\n\/\/  func readLoop(c *websocket.Conn) {\n\/\/      for {\n\/\/          if _, _, err := c.NextReader(); err != nil {\n\/\/              c.Close()\n\/\/              break\n\/\/          }\n\/\/      }\n\/\/  }\n\/\/\n\/\/ Concurrency\n\/\/\n\/\/ Connections support one concurrent reader and one concurrent writer.\n\/\/\n\/\/ Applications are responsible for ensuring that no more than one goroutine\n\/\/ calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,\n\/\/ WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and\n\/\/ that no more than one goroutine calls the read methods (NextReader,\n\/\/ SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler)\n\/\/ concurrently.\n\/\/\n\/\/ The Close and WriteControl methods can be called concurrently with all other\n\/\/ methods.\n\/\/\n\/\/ Origin Considerations\n\/\/\n\/\/ Web browsers allow Javascript applications to open a WebSocket connection to\n\/\/ any host. It's up to the server to enforce an origin policy using the Origin\n\/\/ request header sent by the browser.\n\/\/\n\/\/ The Upgrader calls the function specified in the CheckOrigin field to check\n\/\/ the origin.

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\/\/ Package websocket implements the WebSocket protocol defined in RFC 6455.\n\/\/\n\/\/ Overview\n\/\/\n\/\/ The Conn type represents a WebSocket connection. A server application calls\n\/\/ the Upgrader.Upgrade method from an HTTP request handler to get a *Conn:\n\/\/\n\/\/  var upgrader = websocket.Upgrader{\n\/\/      ReadBufferSize:  1024,\n\/\/      WriteBufferSize: 1024,\n\/\/  }\n\/\/\n\/\/  func handler(w http.ResponseWriter, r *http.Request) {\n\/\/      conn, err := upgrader.Upgrade(w, r, nil)\n\/\/      if err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/      ... Use conn to send and receive messages.\n\/\/  }\n\/\/\n\/\/ Call the connection's WriteMessage and ReadMessage methods to send and\n\/\/ receive messages as a slice of bytes. This snippet of code shows how to echo\n\/\/ messages using these methods:\n\/\/\n\/\/  for {\n\/\/      messageType, p, err := conn.ReadMessage()\n\/\/      if err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/      if err := conn.WriteMessage(messageType, p); err != nil {\n\/\/          log.Println(err)\n\/\/          return\n\/\/      }\n\/\/  }\n\/\/\n\/\/ In above snippet of code, p is a []byte and messageType is an int with value\n\/\/ websocket.BinaryMessage or websocket.TextMessage.\n\/\/\n\/\/ An application can also send and receive messages using the io.WriteCloser\n\/\/ and io.Reader interfaces. To send a message, call the connection NextWriter\n\/\/ method to get an io.WriteCloser, write the message to the writer and close\n\/\/ the writer when done. To receive a message, call the connection NextReader\n\/\/ method to get an io.Reader and read until io.EOF is returned. This snippet\n\/\/ shows how to echo messages using the NextWriter and NextReader methods:\n\/\/\n\/\/  for {\n\/\/      messageType, r, err := conn.NextReader()\n\/\/      if err != nil {\n\/\/          return\n\/\/      }\n\/\/      w, err := conn.NextWriter(messageType)\n\/\/      if err != nil {\n\/\/          return err\n\/\/      }\n\/\/      if _, err := io.Copy(w, r); err != nil {\n\/\/          return err\n\/\/      }\n\/\/      if err := w.Close(); err != nil {\n\/\/          return err\n\/\/      }\n\/\/  }\n\/\/\n\/\/ Data Messages\n\/\/\n\/\/ The WebSocket protocol distinguishes between text and binary data messages.\n\/\/ Text messages are interpreted as UTF-8 encoded text. The interpretation of\n\/\/ binary messages is left to the application.\n\/\/\n\/\/ This package uses the TextMessage and BinaryMessage integer constants to\n\/\/ identify the two data message types. The ReadMessage and NextReader methods\n\/\/ return the type of the received message. The messageType argument to the\n\/\/ WriteMessage and NextWriter methods specifies the type of a sent message.\n\/\/\n\/\/ It is the application's responsibility to ensure that text messages are\n\/\/ valid UTF-8 encoded text.\n\/\/\n\/\/ Control Messages\n\/\/\n\/\/ The WebSocket protocol defines three types of control messages: close, ping\n\/\/ and pong. Call the connection WriteControl, WriteMessage or NextWriter\n\/\/ methods to send a control message to the peer.\n\/\/\n\/\/ Connections handle received close messages by calling the handler function\n\/\/ set with the SetCloseHandler method and by returning a *CloseError from the\n\/\/ NextReader, ReadMessage or the message Read method. The default close\n\/\/ handler sends a close message to the peer.\n\/\/\n\/\/ Connections handle received ping messages by calling the handler function\n\/\/ set with the SetPingHandler method. The default ping handler sends a pong\n\/\/ message to the peer.\n\/\/\n\/\/ Connections handle received pong messages by calling the handler function\n\/\/ set with the SetPongHandler method. The default pong handler does nothing.\n\/\/ If an application sends ping messages, then the application should set a\n\/\/ pong handler to receive the corresponding pong.\n\/\/\n\/\/ The control message handler functions are called from the NextReader,\n\/\/ ReadMessage and message reader Read methods. The default close and ping\n\/\/ handlers can block these methods for a short time when the handler writes to\n\/\/ the connection.\n\/\/\n\/\/ The application must read the connection to process close, ping and pong\n\/\/ messages sent from the peer. If the application is not otherwise interested\n\/\/ in messages from the peer, then the application should start a goroutine to\n\/\/ read and discard messages from the peer. A simple example is:\n\/\/\n\/\/  func readLoop(c *websocket.Conn) {\n\/\/      for {\n\/\/          if _, _, err := c.NextReader(); err != nil {\n\/\/              c.Close()\n\/\/              break\n\/\/          }\n\/\/      }\n\/\/  }\n\/\/\n\/\/ Concurrency\n\/\/\n\/\/ Connections support one concurrent reader and one concurrent writer.\n\/\/\n\/\/ Applications are responsible for ensuring that no more than one goroutine\n\/\/ calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,\n\/\/ WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and\n\/\/ that no more than one goroutine calls the read methods (NextReader,\n\/\/ SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler)\n\/\/ concurrently.\n\/\/\n\/\/ The Close and WriteControl methods can be called concurrently with all other\n\/\/ methods.\n\/\/\n\/\/ Origin Considerations\n\/\/\n\/\/ Web browsers allow Javascript applications to open a WebSocket connection to\n\/\/ any host. It's up to the server to enforce an origin policy using the Origin\n\/\/ request header sent by the browser.\n\/\/\n\/\/ The Upgrader calls the function specified in the CheckOrigin field to check\n\/\/ the origin. If the CheckOrigin function returns false, then the Upgrade\n\/\/ method fails the WebSocket handshake with HTTP status 403.\n\/\/\n\/\/ If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail\n\/\/ the handshake if the Origin request header is present and the Origin host is\n\/\/ not equal to the Host request header.\n\/\/\n\/\/ The deprecated package-level Upgrade function does not perform origin\n\/\/ checking. The application is responsible for checking the Origin header\n\/\/ before calling the Upgrade function.\n\/\/\n\/\/ Buffers\n\/\/\n\/\/ Connections buffer network input and output to reduce the number\n\/\/ of system calls when reading or writing messages.\n\/\/\n\/\/ Write buffers are also used for constructing WebSocket frames. See RFC 6455,\n\/\/ Section 5 for a discussion of message framing. A WebSocket frame header is\n\/\/ written to the network each time a write buffer is flushed to the network.\n\/\/ Decreasing the size of the write buffer can increase the amount of framing\n\/\/ overhead on the connection.\n\/\/\n\/\/ The buffer sizes in bytes are specified by the ReadBufferSize and\n\/\/ WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default\n\/\/ size of 4096 when a buffer size field is set to zero. The Upgrader reuses\n\/\/ buffers created by the HTTP server when a buffer size field is set to zero.\n\/\/ The HTTP server buffers have a size of 4096 at the time of this writing.\n\/\/\n\/\/ The buffer sizes do not limit the size of a message that can be read or\n\/\/ written by a connection.\n\/\/\n\/\/ Buffers are held for the lifetime of the connection by default. If the\n\/\/ Dialer or Upgrader WriteBufferPool field is set, then a connection holds the\n\/\/ write buffer only when writing a message.\n\/\/\n\/\/ Applications should tune the buffer sizes to balance memory use and\n\/\/ performance. Increasing the buffer size uses more memory, but can reduce the\n\/\/ number of system calls to read or write the network. In the case of writing,\n\/\/ increasing the buffer size can reduce the number of frame headers written to\n\/\/ the network.\n\/\/\n\/\/ Some guidelines for setting buffer parameters are:\n\/\/\n\/\/ Limit the buffer sizes to the maximum expected message size. Buffers larger\n\/\/ than the largest message do not provide any benefit.\n\/\/\n\/\/ Depending on the distribution of message sizes, setting the buffer size to\n\/\/ to a value less than the maximum expected message size can greatly reduce\n\/\/ memory use with a small impact on performance. Here's an example: If 99% of\n\/\/ the messages are smaller than 256 bytes and the maximum message size is 512\n\/\/ bytes, then a buffer size of 256 bytes will result in 1.01 more system calls\n\/\/ than a buffer size of 512 bytes. The memory savings is 50%.\n\/\/\n\/\/ A write buffer pool is useful when the application has a modest number\n\/\/ writes over a large number of connections. when buffers are pooled, a larger\n\/\/ buffer size has a reduced impact on total memory use and has the benefit of\n\/\/ reducing system calls and frame overhead.\n\/\/\n\/\/ Compression EXPERIMENTAL\n\/\/\n\/\/ Per message compression extensions (RFC 7692) are experimentally supported\n\/\/ by this package in a limited capacity. Setting the EnableCompression option\n\/\/ to true in Dialer or Upgrader will attempt to negotiate per message deflate\n\/\/ support.\n\/\/\n\/\/  var upgrader = websocket.Upgrader{\n\/\/      EnableCompression: true,\n\/\/  }\n\/\/\n\/\/ If compression was successfully negotiated with the connection's peer, any\n\/\/ message received in compressed form will be automatically decompressed.\n\/\/ All Read methods will return uncompressed bytes.\n\/\/\n\/\/ Per message compression of messages written to a connection can be enabled\n\/\/ or disabled by calling the corresponding Conn method:\n\/\/\n\/\/  conn.EnableWriteCompression(false)\n\/\/\n\/\/ Currently this package does not support compression with \"context takeover\".\n\/\/ This means that messages must be compressed and decompressed in isolation,\n\/\/ without retaining sliding window or dictionary state across messages.

This allows the service to determine\n\/\/ the best IP address for contacting the peer.\n\/\/\n\/\/     addrs, _ := s.PeerAddrs(id)\n\/\/     for _, a := range addrs {\n\/\/         fmt.Printf(\"- %s\", a)\n\/\/     }\n\/\/\n\/\/ Note that you may want to filter the addresses since the slice may contain\n\/\/ both IPv4 and IPv6 addresses.\n\/\/\n\/\/ The service can be shutdown by invoking the Stop() method:\n\/\/\n\/\/     s.Stop()\n\/\/\npackage sdiscovery\n<|endoftext|>"}
