If a\n\t\/\/ tracing system does not know how to handle a particular value type, it\n\t\/\/ may ignore the tag, but shall not panic.\n\tSetTag(key string, value interface{}) Span\n\n\t\/\/ LogFields is an efficient and type-checked way to record key:value\n\t\/\/ logging data about a Span, though the programming interface is a little\n\t\/\/ more verbose than LogKV(). Here's an example:\n\t\/\/\n\t\/\/    span.LogFields(\n\t\/\/        log.String(\"event\", \"soft error\"),\n\t\/\/        log.String(\"type\", \"cache timeout\"),\n\t\/\/        log.Int(\"waited.millis\", 1500))\n\t\/\/\n\t\/\/ Also see Span.FinishWithOptions() and FinishOptions.BulkLogData.\n\tLogFields(fields ...log.Field)\n\n\t\/\/ LogKV is a concise, readable way to record key:value logging data about\n\t\/\/ a Span, though unfortunately this also makes it less efficient and less\n\t\/\/ type-safe than LogFields(). Here's an example:\n\t\/\/\n\t\/\/    span.LogKV(\n\t\/\/        \"event\", \"soft error\",\n\t\/\/        \"type\", \"cache timeout\",\n\t\/\/        \"waited.millis\", 1500)\n\t\/\/\n\t\/\/ For LogKV (as opposed to LogFields()), the parameters must appear as\n\t\/\/ key-value pairs, like\n\t\/\/\n\t\/\/    span.LogKV(key1, val1, key2, val2, key3, val3, ...)\n\t\/\/\n\t\/\/ The keys must all be strings. The values may be strings, numeric types,\n\t\/\/ bools, Go error instances, or arbitrary structs.\n\t\/\/\n\t\/\/ (Note to implementors: consider the log.InterleavedKVToFields() helper)\n\tLogKV(alternatingKeyValues ...interface{})\n\n\t\/\/ SetBaggageItem sets a key:value pair on this Span and its SpanContext\n\t\/\/ that also propagates to descendants of this Span.\n\t\/\/\n\t\/\/ SetBaggageItem() enables powerful functionality given a full-stack\n\t\/\/ opentracing integration (e.g., arbitrary application data from a mobile\n\t\/\/ app can make it, transparently, all the way into the depths of a storage\n\t\/\/ system), and with it some powerful costs: use this feature with care.\n\t\/\/\n\t\/\/ IMPORTANT NOTE #1: SetBaggageItem() will only propagate baggage items to\n\t\/\/ *future* causal descendants of the associated Span.\n\t\/\/\n\t\/\/ IMPORTANT NOTE #2: Use this thoughtfully and with care. Every key and\n\t\/\/ value is copied into every local *and remote* child of the associated\n\t\/\/ Span, and that can add up to a lot of network and cpu overhead.\n\t\/\/\n\t\/\/ Returns a reference to this Span for chaining.\n\tSetBaggageItem(restrictedKey, value string) Span\n\n\t\/\/ Gets the value for a baggage item given its key. Returns the empty string\n\t\/\/ if the value isn't found in this Span.\n\tBaggageItem(restrictedKey string) string\n\n\t\/\/ Provides access to the Tracer that created this Span.\n\tTracer() Tracer\n\n\t\/\/ Deprecated: use LogFields or LogKV\n\tLogEvent(event string)\n\t\/\/ Deprecated: use LogFields or LogKV\n\tLogEventWithPayload(event string, payload interface{})\n\t\/\/ Deprecated: use LogFields or LogKV\n\tLog(data LogData)\n}\n\n\/\/ LogRecord is data associated with a single Span log. Every LogRecord\n\/\/ instance must specify at least one Field.\ntype LogRecord struct {\n\tTimestamp time.Time\n\tFields    []log.Field\n}\n\n\/\/ FinishOptions allows Span.FinishWithOptions callers to override the finish\n\/\/ timestamp and provide log data via a bulk interface.\ntype FinishOptions struct {\n\t\/\/ FinishTime overrides the Span's finish time, or implicitly becomes\n\t\/\/ time.Now() if FinishTime.IsZero().\n\t\/\/\n\t\/\/ FinishTime must resolve to a timestamp that's >= the Span's StartTime\n\t\/\/ (per StartSpanOptions).\n\tFinishTime time.Time\n\n\t\/\/ LogRecords allows the caller to specify the contents of many LogFields()\n\t\/\/ calls with a single slice. May be nil.\n\t\/\/\n\t\/\/ None of the LogRecord.Timestamp values may be .IsZero() (i.e., they must\n\t\/\/ be set explicitly). Also, they must be >= the Span's start timestamp and\n\t\/\/ <= the FinishTime (or time.Now() if FinishTime.IsZero()). Otherwise the\n\t\/\/ behavior of FinishWithOptions() is undefined.\n\t\/\/\n\t\/\/ If specified, the caller hands off ownership of LogRecords at\n\t\/\/ FinishWithOptions() invocation time.\n\t\/\/\n\t\/\/ If specified, the (deprecated) BulkLogData must be nil or empty.\n\tLogRecords []LogRecord\n\n\t\/\/ BulkLogData is DEPRECATED.\n\tBulkLogData []LogData\n}\n\n\/\/ LogData is DEPRECATED\ntype LogData struct {\n\tTimestamp time.Time\n\tEvent     string\n\tPayload   interface{}\n}\n\n\/\/ ToLogRecord converts a deprecated LogData to a non-deprecated LogRecord\nfunc (ld *LogData) ToLogRecord() LogRecord {\n\tvar literalTimestamp time.Time\n\tif ld.Timestamp.IsZero() {\n\t\tliteralTimestamp = time.Now()\n\t} else {\n\t\tliteralTimestamp = ld.Timestamp\n\t}\n\trval := LogRecord{\n\t\tTimestamp: literalTimestamp,\n\t}\n\tif ld.Payload == nil {\n\t\trval.Fields = []log.Field{\n\t\t\tlog.String(\"event\", ld.Event),\n\t\t}\n\t} else {\n\t\trval.Fields = []log.Field{\n\t\t\tlog.String(\"event\", ld.Event),\n\t\t\tlog.Object(\"payload\", ld.Payload),\n\t\t}\n\t}\n\treturn rval\n}\n<|endoftext|>"}

See the License for the specific language governing permissions and\n\/\/ limitations under the License.\n\n\/\/ The approach taken here was inspired by an example on the gonuts mailing list by Roger Peppe.\n\/*\n  REVISION HISTORY\n  ----------------\n   1 Apr 20 -- Making it multi-threaded by using go routines by copying cgrepi.go and multimap.go.\n               Now created multack.go, derived from anack.go.\n               With a ResultType buffer of   1,024 items, it's  <1% faster than anack, if that much.\n               With a ResultType buffer of  10,000 items, it's  ~5% faster than anack.\n               With a ResultType buffer of  50,000 items, it's ~15% faster than anack.\n               With a ResultType buffer of 100,000 items, it's ~24% faster than anack.\n               I'll stop at 100,000 items.  It's great it works.\n\n   2 Apr 20 -- Updated its start string to declare its correct name.  I forgot to change that yesterday.\n  23 Apr 20 -- 2 edge cases don't work on linux.  If there is a filepattern but no matching files in the start directory,\n                and if there is only 1 matching file in the start directory.\n                And also if there appears to be more than one extension, like gastric.txt.out.\n   5 Sep 20 -- Will not search thru symlinked directories\n  27 Mar 21 -- making sure that the filename matches are case insensitive\n   6 Dec 21 -- Maybe something I'm learning from Bill Kennedy applies here.  I only made the doneChan buffered.\n   7 Dec 21 -- Extensions like .xls will also match .xlsm, .xlsx, etc.  And I don't think I have to track which directories I've visited, as the library func does that.\n                 So I'll just use the map as a list of known directories to skip.  So far, only \".git\" is skipped.\n                 And I don't have to check for IsDir() or IsRegular(), so I removed that, also.\n               Starting w\/ Go 1.16, there is a new walk function, that does not use a FiloInfo but a dirEntry, which they claim is faster.

It's great it works.\n\n   2 Apr 20 -- Updated its start string to declare its correct name.  I forgot to change that yesterday.\n  23 Apr 20 -- 2 edge cases don't work on linux.  If there is a filepattern but no matching files in the start directory,\n                and if there is only 1 matching file in the start directory.\n                And also if there appears to be more than one extension, like gastric.txt.out.\n   5 Sep 20 -- Will not search thru symlinked directories\n  27 Mar 21 -- making sure that the filename matches are case insensitive\n   6 Dec 21 -- Maybe something I'm learning from Bill Kennedy applies here.  I only made the doneChan buffered.\n   7 Dec 21 -- Extensions like .xls will also match .xlsm, .xlsx, etc.  And I don't think I have to track which directories I've visited, as the library func does that.\n                 So I'll just use the map as a list of known directories to skip.  So far, only \".git\" is skipped.\n                 And I don't have to check for IsDir() or IsRegular(), so I removed that, also.\n               Starting w\/ Go 1.16, there is a new walk function, that does not use a FiloInfo but a dirEntry, which they claim is faster.  I'll try it.\n   8 Dec 21 -- Will output when .git gets skipped, and will use the pattern of signalling without data, as I learned from Bill Kennedy.\n  10 Dec 21 -- I'm testing for .git and will skipdir if found.

The given imageRef can be an image ID, ID prefix, or a repository\n\/\/ reference (with an optional tag or digest, defaulting to the tag name\n\/\/ \"latest\"). There is differing behavior depending on whether the given\n\/\/ imageRef is a repository reference or not.\n\/\/\n\/\/ If the given imageRef is a repository reference then that repository\n\/\/ reference will be removed. However, if there exists any containers which\n\/\/ were created using the same image reference then the repository reference\n\/\/ cannot be removed unless either there are other repository references to the\n\/\/ same image or force is true. Following removal of the repository reference,\n\/\/ the referenced image itself will attempt to be deleted as described below\n\/\/ but quietly, meaning any image delete conflicts will cause the image to not\n\/\/ be deleted and the conflict will not be reported.\n\/\/\n\/\/ There may be conflicts preventing deletion of an image and these conflicts\n\/\/ are divided into two categories grouped by their severity:\n\/\/\n\/\/ Hard Conflict:\n\/\/ \t- a pull or build using the image.\n\/\/ \t- any descendant image.\n\/\/ \t- any running container using the image.\n\/\/\n\/\/ Soft Conflict:\n\/\/ \t- any stopped container using the image.\n\/\/ \t- any repository tag or digest references to the image.\n\/\/\n\/\/ The image cannot be removed if there are any hard conflicts and can be\n\/\/ removed if there are soft conflicts only if force is true.\n\/\/\n\/\/ If prune is true, ancestor images will each attempt to be deleted quietly,\n\/\/ meaning any delete conflicts will cause the image to not be deleted and the\n\/\/ conflict will not be reported.\n\/\/\n\/\/ FIXME: remove ImageDelete's dependency on Daemon, then move to the graph\n\/\/ package.

All rights reserved.\n\/\/ Use of this source code is governed by a BSD-style\n\/\/ license that can be found in the LICENSE.md file.\n\n\/\/ udptunnel is a daemon that sets up a point-to-point virtual private network\n\/\/ between two hosts:\n\/\/\t* A client host that may be behind an obtrusive NAT that frequently drops\n\/\/\tTCP connections, but happens to pass UDP traffic reliably.\n\/\/\t* A server host that is internet-accessible.\n\/\/\n\/\/ Example Setup\n\/\/\n\/\/ The udptunnel is setup by running it on two different hosts, one in a server\n\/\/ configuration, and the other in client configuration. The difference between\n\/\/ a server or client is determined by the NetworkAddress field in the\n\/\/ configuration. If the address has an empty host portion, then the daemon\n\/\/ operates in server mode. Otherwise, the daemon operates in client mode and\n\/\/ will use the host to dial the server.\n\/\/\n\/\/ Example server config:\n\/\/\t{\"TunnelAddress\": \"10.0.0.1\", \"NetworkAddress\": \":8000\", \"AllowedPorts\": [22]}\n\/\/ Example client config:\n\/\/\t{\"TunnelAddress\": \"10.0.0.2\", \"NetworkAddress\": \"example.com:8000\", \"AllowedPorts\": [22]}\n\/\/\n\/\/ See the TunnelConfig struct for more details.\n\/\/\n\/\/ Security Considerations\n\/\/\n\/\/ TUN traffic is sent ad-verbatim between the two endpoints via unencrypted\n\/\/ UDP traffic. The intended use case is to run a secure protocol (like SSH;\n\/\/ see github.com\/dsnet\/sshtunnel) on top of this simple VPN. In order to\n\/\/ prevent attackers from connecting to other locally binded sockets on the\n\/\/ endpoints, a simple port filter is built-in to restrict IP traffic to only\n\/\/ the specified ports. Users of udptunnel should also setup iptable rules as\n\/\/ a secondary measure to restrict malicious traffic.\npackage main\n\nimport (\n\t\"bytes\"\n\t\"context\"\n\t\"crypto\/md5\"\n\t\"encoding\/json\"\n\t\"fmt\"\n\t\"io\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"net\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"os\/signal\"\n\t\"sync\/atomic\"\n\t\"syscall\"\n\t\"time\"\n\n\t\"github.com\/dsnet\/golib\/jsonutil\"\n\t\"github.com\/songgao\/water\"\n)\n\ntype TunnelConfig struct {\n\t\/\/ LogFile is where the tunnel daemon will direct its output log.\n\t\/\/ If the path is empty, then the server will output to os.Stderr.\n\tLogFile string\n\n\t\/\/ TunnelDevice is the name of the TUN device (default: \"tunnel\").\n\tTunnelDevice string\n\n\t\/\/ TunnelAddress is the private IPv4 address for the tunnel.\n\t\/\/ The client and server should have different IP addresses both in the\n\t\/\/ 255.255.255.0 subnet mask.\n\t\/\/ Recommended value is 10.0.0.1 for the server and 10.0.0.2 for the client.\n\tTunnelAddress string\n\n\t\/\/ NetworkAddress is the public host and port for UDP traffic.\n\t\/\/ If the host portion is empty, then the daemon is operting operating in\n\t\/\/ server mode and will bind on the specified port (e.g., \":8000\").\n\t\/\/ Otherwise, the daemon is operating in client mode and will use the\n\t\/\/ specified host to communicate with the server (e.g., \"example.com:8000\").\n\tNetworkAddress string\n\n\t\/\/ AllowedPorts is a list of allowed UDP and TCP ports.\n\t\/\/ Since udptunnel sends traffic as unencrypted messages,\n\t\/\/ only protocols that provide application-layer security (like SSH)\n\t\/\/ should be used.\n\t\/\/\n\t\/\/ The set of allowed ports must match on both the client and server.\n\tAllowedPorts []uint16\n\n\t\/\/ PacketMagic is used to generate a sequence of bytes that is prepended to\n\t\/\/ every TUN packet sent over UDP.

The difference between\n\/\/ a server or client is determined by the NetworkAddress field in the\n\/\/ configuration. If the address has an empty host portion, then the daemon\n\/\/ operates in server mode. Otherwise, the daemon operates in client mode and\n\/\/ will use the host to dial the server.\n\/\/\n\/\/ Example server config:\n\/\/\t{\"TunnelAddress\": \"10.0.0.1\", \"NetworkAddress\": \":8000\", \"AllowedPorts\": [22]}\n\/\/ Example client config:\n\/\/\t{\"TunnelAddress\": \"10.0.0.2\", \"NetworkAddress\": \"example.com:8000\", \"AllowedPorts\": [22]}\n\/\/\n\/\/ See the TunnelConfig struct for more details.\n\/\/\n\/\/ Security Considerations\n\/\/\n\/\/ TUN traffic is sent ad-verbatim between the two endpoints via unencrypted\n\/\/ UDP traffic. The intended use case is to run a secure protocol (like SSH;\n\/\/ see github.com\/dsnet\/sshtunnel) on top of this simple VPN. In order to\n\/\/ prevent attackers from connecting to other locally binded sockets on the\n\/\/ endpoints, a simple port filter is built-in to restrict IP traffic to only\n\/\/ the specified ports. Users of udptunnel should also setup iptable rules as\n\/\/ a secondary measure to restrict malicious traffic.\npackage main\n\nimport (\n\t\"bytes\"\n\t\"context\"\n\t\"crypto\/md5\"\n\t\"crypto\/sha256\"\n\t\"encoding\/json\"\n\t\"fmt\"\n\t\"io\"\n\t\"io\/ioutil\"\n\t\"log\"\n\t\"net\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"os\/signal\"\n\t\"sync\/atomic\"\n\t\"syscall\"\n\t\"time\"\n\n\t\"github.com\/dsnet\/golib\/jsonutil\"\n\t\"github.com\/songgao\/water\"\n)\n\n\/\/ Version of the udptunnel binary.

{"text":"<commit_before>\/*\nForce12.io is a package that monitors demand for resource in a system and then scales and repurposes\ncontainers, based on agreed \"quality of service\" contracts, to best handle that demand within the constraints of your existing VM or physical infrastructure (for v1).\n\nForce12 is defined to optimize the use of existing physical and VM resources instantly. VMs cannot be scaled in real time (it takes several minutes) and new physical machines take even longer. However, containers can be started or stopped at sub second speeds, allowing your infrastructure to adapt itself in real time to meet system demands.\n\nForce12 is aimed at effectively using the resources you have right now - your existing VMs or physical servers - by using them as optimally as possible.\n\nThe Force12 approach is analogous to the way that a router dynamically optimises the use of a physical network. A router is limited by the capacity of the lines physically connected to it. Adding additional capacity is a physical process and takes time. Routers therefore make decisions in real time about which packets will be prioritized on a particular line based on the packet's priority (defined by a \"quality of service\" contract).\n\nFor example, at times of high bandwidth usage a router might prioritize VOIP traffic over web browsing in real time.\n\nContainers allow Force12 to make similar \"instant\" judgements on service prioritisation within your existing infrastructure. Routers make very simplistic\njudgments because they have limited time and cpu and they act at a per packet level. Force12 has the capability of making far more\nsophisticated judgements, although even fairly simple ones will still provide a significant new service.\n\nThis prototype is a bare bones implementation of Force12.io that recognises only 1 demand types\nrandomised demand for a priority 1 service (the current value stored in Consul's key value store) aka \"client\". WHen this minimum demand has been met then a P2 service will\nbe run (aka \"server).\n\nThese demand type examples have been chosen purely for simplicity of demonstration. In the future more demand types\nwill be offered\n\nV1 - Force12.io reacts to increased demand by starting\/stopping containers on the slaves already in play.\n\nNote - this version of Force12 starts and stops containers on a Mesos cluser using Marathon as the scheduler\n*\/\n\npackage main\n\nimport (\n\t\"log\"\n\t\"os\"\n\t\"time\"\n\n\t\"bitbucket.org\/force12io\/force12-scheduler\/marathon\"\n\t\"bitbucket.org\/force12io\/force12-scheduler\/scheduler\"\n)\n\n\/\/CONSTANTS\nconst const_sleep = 100     \/\/milliseconds\nconst const_stopsleep = 250 \/\/milliseconds pause between stopping and restarting containers\nconst const_clientdemandstart int = 5\nconst const_serverdemandstart int = 4\nconst const_maxcontainers int = 9\n\n\/\/EXPORTED STRUCTS\ntype Demand struct {\n\tsched scheduler.Scheduler\n\n\t\/\/  mu  sync.Mutex   \/\/ plan ahead for concurrency on this potentially shared resource, this is go after all\n\tclientdemand     int \/\/ indicates number of clients demanded (from dynamo table in prototype)\n\tserverdemand     int \/\/ indicates server demand (deduced in prototype)\n\tclientsrequested int \/\/ indicates how many clients we've tried to kick off.\n\tserversrequested int \/\/ indicates how many servers we've tried to kick off.\n}\n\n\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\n\/\/ set\n\/\/ Setter, returns what was there (client, server)\n\/\/ if provided value is -1 don't update, demand will always be between 0 and const_maxcontainers\nfunc (d *Demand) set(client, server int) (int, int) {\n\t\/\/d.mu.Lock()\n\tserverold := d.serverdemand\n\tclientold := d.clientdemand\n\tif server != -1 {\n\t\td.serverdemand = server\n\t}\n\tif client != -1 {\n\t\td.clientdemand = client\n\t}\n\t\/\/d.mu.Unlock()\n\treturn clientold, serverold\n}\n\n\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\n\/\/ get\n\/\/ Getter, returns client, server AEC - Combine this with the set to reduce code\nfunc (d *Demand) get() (int, int) {\n\treturn d.clientdemand, d.serverdemand\n}\n\n\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\n\/\/ handle\n\/\/\n\/\/ Called in response to a change in demand to process it.\n\/\/\n\/\/ output err - true if success (AEC currently assumes success).\n\/\/\n\/\/ Note that handle will make any judgment on what to do with a demand\n\/\/ change, including potentially nothing.\n\/\/\nfunc (d *Demand) handle() bool {\n\tlog.Println(\"Handle demand change.\")\n\n\t\/\/ AEC NOTE THIS FUNCTION NEEDS TO BE HEAVILY REWRITTEN TO HANDLE ECS\n\t\/\/ WHEN WE PORT THAT OVER TO THE SAME STRUCTURE.\n\t\/\/ THe reason is that all the code we wrote to handle stopping before\n\t\/\/ starting etc.. is handled directly by Marathon so that code\n\t\/\/ from the old scheduler needs to go behind the scheduler interface\n\terr := d.sched.StopStartNTasks(os.Getenv(\"CLIENT_TASK\"), os.Getenv(\"CLIENT_FAMILY\"), d.clientdemand, d.clientsrequested)\n\tif err != nil {\n\t\tlog.Printf(\"Failed to start client tasks. %v\", err)\n\t}\n\td.sched.StopStartNTasks(os.Getenv(\"SERVER_TASK\"), os.Getenv(\"SERVER_FAMILY\"), d.serverdemand, d.serversrequested)\n\tif err != nil {\n\t\tlog.Printf(\"Failed to start server tasks. %v\", err)\n\t}\n\n\treturn false\n}\n\n\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\n\/\/ update\n\/\/\n\/\/ Called periodically to check for changes in demand and update accordingly.\n\/\/\n\/\/ output changed? - true if demand changed\n\/\/\n\/\/ Note that this routine will return any change.

A remote\nin git usually only gives you the real git repo, so git-lob needs to expand\nthe configuration parameters to git remotes to specify the location of the \ncorresponding remote binary store. \n\nThe <remote> parameter refers to a named remote in .git\/config (plain URLs \ncannot be supported). The remote entry itself is the same as any normal git\nremote, except that it requires additional git-lob specific parameters. The\nparameters depend on the type of binary storage ('provider') being used; see\n'git-lob providers' for a list of available providers and \n'git-lob provider <provider>' for specific details of one provider.\n\nAs an example, let's take the 'filesystem' provider, which simply uses the OS's\nfile system as a remote transport (obviously very simplistic):\n\n[remote \"origin\"]\n    # these 2 lines are standard git\n    url = ssh:\/\/git@bitbucket.org\/something\/somthing.git\n    fetch = +refs\/heads\/*:refs\/remotes\/origin\/*\n    # these next 2 lines are required to configure the remote binary store\n    git-lob-provider = filesystem\n    git-lob-path = \/Volumes\/shared\/something\/something\/binary\/store\n    \nOther providers may require other parameters. It's important to note that you\ncan share a binary store among multiple remote repos if you wish, much like\nthe local git-lob.sharedstore option, since binaries are stored by SHA. \nIdentical file content in multiple repos can be stored only once this way.\nOf course, access control may be an issue to consider here though.\n\nHISTORY CHECKING\n\nWhen pushing binaries for a given ref, git-lob performs a search for commits\nwhich reference git-lob binaries from that ref backwards, before checking\nwhich of those binaries it needs to upload. This is so that we only upload\nbinaries that are actually referenced by the ref you're choosing to push, \nand don't waste time on binaries in unpublished feature branches etc. \n\nBecause searching the whole of the git history can be slow on large \nrepositories, git-lob speeds this search up by keeping a record of which \ncommits it believes the remote already has all binaries for. \n\nThese records are updated whenever you git-lob push\/pull. We do not use git's\nown remote branch refs to track this, because pushing commits can be done\ncompletely separately from binaries so we can't rely on that information.\nSo pushing and pulling branches in git has no effect on this state, only\ngit-lob push\/pull.\n\nIf for some reason these records are wrong, and you need to push binaries\nfor a bigger range of commits, you can do this 2 ways:\n\n1. Use the --recheck option. This is the 'nuclear option'; it will scan the\n   entire history of the repo again to make 100% sure everything is correct.\n   Can take a while on large repos.\n\n2. Use a commit range for <ref>, i.e. <ref1>..<ref2>. git-lob will check that\n   entire range of commits for binary references which will then be checked\n   with the remote. \n\nThere are not many circumstances where you need to manually override the commit\nrange that is checked for binaries. Even if you edit commits, rebase etc, \ngit-lob should not miss any binaries, because the commit SHAs would change and\nit would know to check any referenced binaries again. The main reason why\nyou would need to override the history checking is if the remote changed, for\nexample if someone manually deleted the remote binary store, or you moved to \na new URL without copying the data and needed to re-populate it from your local\nrepo.\n\n`)\n}\n<commit_msg>Include some progress reporting in push command line<commit_after>package main\n\nimport (\n\t\"fmt\"\n\t\"os\"\n\t\"strings\"\n)\n\n\/\/ Push command line tool\nfunc cmdPush() int {\n\n\t\/\/ git-lob push [--all] [--recheck] [--force] [<remote> [<ref>...]]\n\n\t\/\/ Validate custom options\n\terrorList := validateCustomOptions(GlobalOptions, nil, []string{\"all\", \"recheck\", \"force\"})\n\tif len(errorList) > 0 {\n\t\tfmt.Fprintf(os.Stderr, strings.Join(errorList, \"\\n\"))\n\t\treturn 9\n\t}\n\n\toptAll := GlobalOptions.BoolOpts.Contains(\"all\")\n\toptRecheck := GlobalOptions.BoolOpts.Contains(\"recheck\")\n\toptForce := GlobalOptions.BoolOpts.Contains(\"force\")\n\n\t\/\/ Determine remote\n\tvar remoteName string\n\tvar refspecs []*GitRefSpec\n\tif len(GlobalOptions.Args) > 0 {\n\t\t\/\/ first parameter must be remote if there are arguments\n\t\tremoteName = GlobalOptions.Args[0]\n\n\t\t\/\/ Remaining args are refspecs\n\t\tif len(GlobalOptions.Args) > 1 {\n\t\t\t\/\/ Not valid if --all\n\t\t\tif optAll {\n\t\t\t\tfmt.Fprintf(os.Stderr, \"git-lob: Too many arguments; cannot include refspec when using --all\\n\")\n\t\t\t\treturn 7\n\t\t\t}\n\t\t\tfor _, arg := range GlobalOptions.Args[1:] {\n\t\t\t\tr := ParseGitRefSpec(arg)\n\t\t\t\trefspecs = append(refspecs, r)\n\t\t\t}\n\t\t}\n\n\t} else {\n\t\tremoteName = GetGitDefaultRemote()\n\t}\n\n\t\/\/ check the remote config to make sure it's valid\n\tprovider, err := GetProviderForRemote(remoteName)\n\tif err != nil {\n\t\tfmt.Fprintf(os.Stderr, \"git-lob: %v\\n\", err)\n\t\treturn 7\n\t}\n\n\tif len(refspecs) == 0 {\n\t\t\/\/ No refspecs specified, so determine default\n\t\tif optAll {\n\t\t\t\/\/ TODO - enumerate all refs & include in refspecs\n\t\t} else {\n\t\t\t\/\/ TODO - determine refspec from current branch & push settings\n\t\t}\n\t}\n\n\tprogress := func(fileInProgress string, isSkipped bool, filepercent, overallpercent int, rate string) (abort bool) {\n\t\t\/\/ Note, no newline, just carriage return to overwrite single line in place\n\t\tif GlobalOptions.Verbose {\n\t\t\t\/\/ report file name too\n\t\t\tif filepercent == 100 {\n\t\t\t\t\/\/ in verbose mode we include newline after reporting file name at 100%\n\t\t\t\tif isSkipped {\n\t\t\t\t\tfmt.Printf(\"\\rSkipped: %v (Up to date)\\n\", fileInProgress)\n\t\t\t\t} else {\n\t\t\t\t\tfmt.Printf(\"\\rPushed: %v 100%%\\n\", fileInProgress)\n\t\t\t\t}\n\t\t\t} else {\n\t\t\t\tfmt.Printf(\"\\rPushing: %v %d%%\\tOverall: %d%%\\t(%v)\", fileInProgress, filepercent, overallpercent, rate)\n\t\t\t}\n\t\t} else {\n\t\t\tfmt.Printf(\"\\rPushing: %d%%\\t(%v)\", overallpercent, rate)\n\t\t}\n\n\t\treturn false\n\n\t}\n\n\tfmt.Println(\"Pushing to \", remoteName)\n\n\tswitch p := provider.(type) {\n\tcase BasicSyncProvider:\n\t\tPushBasic(p, remoteName, refspecs, optForce, optRecheck, progress)\n\tcase SmartSyncProvider:\n\t\tPushSmart(p, remoteName, refspecs, optForce, optRecheck, progress)\n\t}\n\n\t\/\/ Because no newlines in progress reporting\n\tfmt.Println()\n\n\treturn 0\n}\n\nfunc PushBasic(provider BasicSyncProvider, remoteName string, refspecs []*GitRefSpec, force bool, recheck bool,\n\tcallback func(fileInProgress string, isSkipped bool, filepercent, overallpercent int, rate string) (abort bool)) {\n\t\/\/ TODO\n}\nfunc PushSmart(provider SmartSyncProvider, remoteName string, refspecs []*GitRefSpec, force bool, recheck bool,\n\tcallback func(fileInProgress string, isSkipped bool, filepercent, overallpercent int, rate string) (abort bool)) {\n\t\/\/ TODO\n}\n\nfunc cmdPushHelp() {\n\tfmt.Println(`Usage: git-lob push [options] [<remote> [<ref>...]]\n\n  Uploads binaries to a remote, sending only binaries required to ensure \n  that remote has the binary resources referenced at a set of commits.\n\n  Behaves much like 'git push' except there are no destination refs, only\n  supporting binary files.\n\nParameters:\n  <remote>: The destination to upload to.

You can specify zero, one, or many local refs.\n            There is no destination ref as in git push.\n\n            If no ref is specified, and --all is not used, remote.*.push \n            is consulted to see what to push, with push.default as a fallback.\n\n            COMMIT RANGES\n\n            You can also specify a range of refs in the form <ref1>..<ref2> to\n            force git-lob push to check a specific range of commits for\n            binaries, instead of using its own records of which commits it\n            thinks are already up to date on this remote. \n            See HISTORY CHECKING below.\n\n\nOptions:\n  --all         Push all branches; cannot be used with other refs.\n  --recheck     Re-check entire commit history to each ref instead of only \n                back to last commit we believe is already pushed. \n                See HISTORY CHECKING below for more details.\n  --force       Always upload files even if the provider believes the file is \n                already present on the remote. You shouldn't need this.\n  --quiet, -q   Print less output\n  --verbose, -v Print more output\n  --dry-run     Don't actually delete anything, just report\n\nREMOTES\n\nBinaries in git-lob are not stored in the regular git repo, but a corresponding\nbinary store must always exist to provide the actual binary content. A remote\nin git usually only gives you the real git repo, so git-lob needs to expand\nthe configuration parameters to git remotes to specify the location of the \ncorresponding remote binary store. \n\nThe <remote> parameter refers to a named remote in .git\/config (plain URLs \ncannot be supported). The remote entry itself is the same as any normal git\nremote, except that it requires additional git-lob specific parameters. The\nparameters depend on the type of binary storage ('provider') being used; see\n'git-lob providers' for a list of available providers and \n'git-lob provider <provider>' for specific details of one provider.\n\nAs an example, let's take the 'filesystem' provider, which simply uses the OS's\nfile system as a remote transport (obviously very simplistic):\n\n[remote \"origin\"]\n    # these 2 lines are standard git\n    url = ssh:\/\/git@bitbucket.org\/something\/somthing.git\n    fetch = +refs\/heads\/*:refs\/remotes\/origin\/*\n    # these next 2 lines are required to configure the remote binary store\n    git-lob-provider = filesystem\n    git-lob-path = \/Volumes\/shared\/something\/something\/binary\/store\n    \nOther providers may require other parameters. It's important to note that you\ncan share a binary store among multiple remote repos if you wish, much like\nthe local git-lob.sharedstore option, since binaries are stored by SHA. \nIdentical file content in multiple repos can be stored only once this way.\nOf course, access control may be an issue to consider here though.\n\nHISTORY CHECKING\n\nWhen pushing binaries for a given ref, git-lob performs a search for commits\nwhich reference git-lob binaries from that ref backwards, before checking\nwhich of those binaries it needs to upload. This is so that we only upload\nbinaries that are actually referenced by the ref you're choosing to push, \nand don't waste time on binaries in unpublished feature branches etc. \n\nBecause searching the whole of the git history can be slow on large \nrepositories, git-lob speeds this search up by keeping a record of which \ncommits it believes the remote already has all binaries for. \n\nThese records are updated whenever you git-lob push\/pull. We do not use git's\nown remote branch refs to track this, because pushing commits can be done\ncompletely separately from binaries so we can't rely on that information.\nSo pushing and pulling branches in git has no effect on this state, only\ngit-lob push\/pull.\n\nIf for some reason these records are wrong, and you need to push binaries\nfor a bigger range of commits, you can do this 2 ways:\n\n1. Use the --recheck option. This is the 'nuclear option'; it will scan the\n   entire history of the repo again to make 100% sure everything is correct.\n   Can take a while on large repos.\n\n2. Use a commit range for <ref>, i.e. <ref1>..<ref2>. git-lob will check that\n   entire range of commits for binary references which will then be checked\n   with the remote. \n\nThere are not many circumstances where you need to manually override the commit\nrange that is checked for binaries. Even if you edit commits, rebase etc, \ngit-lob should not miss any binaries, because the commit SHAs would change and\nit would know to check any referenced binaries again. The main reason why\nyou would need to override the history checking is if the remote changed, for\nexample if someone manually deleted the remote binary store, or you moved to \na new URL without copying the data and needed to re-populate it from your local\nrepo.\n\n`)\n}\n<|endoftext|>"}

{"text":"<commit_before>\/\/ Force12.io is a package that monitors demand for resource in a system and then scales and repurposes\n\/\/ containers, based on agreed \"quality of service\" contracts, to best handle that demand within the constraints of your existing VM\n\/\/ or physical infrastructure (for v1).\n\/\/\n\/\/ Force12 is defined to optimize the use of existing physical and VM resources instantly. VMs cannot be scaled in real time (it takes\n\/\/ several minutes) and new physical machines take even longer. However, containers can be started or stopped at sub second speeds,\n\/\/ allowing your infrastructure to adapt itself in real time to meet system demands.\n\/\/\n\/\/ Force12 is aimed at effectively using the resources you have right now - your existing VMs or physical servers - by using them as\n\/\/ optimally as possible.\n\/\/\n\/\/ The Force12 approach is analogous to the way that a router dynamically optimises the use of a physical network. A router is limited\n\/\/ by the capacity of the lines physically connected to it. Adding additional capacity is a physical process and takes time. Routers\n\/\/ therefore make decisions in real time about which packets will be prioritized on a particular line based on the packet's priority\n\/\/ (defined by a \"quality of service\" contract).\n\/\/\n\/\/ For example, at times of high bandwidth usage a router might prioritize VOIP traffic over web browsing in real time.\n\/\/\n\/\/ Containers allow Force12 to make similar \"instant\" judgements on service prioritisation within your existing infrastructure. Routers\n\/\/ make very simplistic judgments because they have limited time and cpu and they act at a per packet level.

Get compiling<commit_after>\/\/ Force12.io is a package that monitors demand for resource in a system and then scales and repurposes\n\/\/ containers, based on agreed \"quality of service\" contracts, to best handle that demand within the constraints of your existing VM\n\/\/ or physical infrastructure (for v1).\n\/\/\n\/\/ Force12 is defined to optimize the use of existing physical and VM resources instantly. VMs cannot be scaled in real time (it takes\n\/\/ several minutes) and new physical machines take even longer. However, containers can be started or stopped at sub second speeds,\n\/\/ allowing your infrastructure to adapt itself in real time to meet system demands.\n\/\/\n\/\/ Force12 is aimed at effectively using the resources you have right now - your existing VMs or physical servers - by using them as\n\/\/ optimally as possible.\n\/\/\n\/\/ The Force12 approach is analogous to the way that a router dynamically optimises the use of a physical network. A router is limited\n\/\/ by the capacity of the lines physically connected to it. Adding additional capacity is a physical process and takes time. Routers\n\/\/ therefore make decisions in real time about which packets will be prioritized on a particular line based on the packet's priority\n\/\/ (defined by a \"quality of service\" contract).\n\/\/\n\/\/ For example, at times of high bandwidth usage a router might prioritize VOIP traffic over web browsing in real time.\n\/\/\n\/\/ Containers allow Force12 to make similar \"instant\" judgements on service prioritisation within your existing infrastructure. Routers\n\/\/ make very simplistic judgments because they have limited time and cpu and they act at a per packet level. Force12 has the capability\n\/\/ of making far more sophisticated judgements, although even fairly simple ones will still provide a significant new service.\n\/\/\n\/\/ This prototype is a bare bones implementation of Force12.io that recognises only 1 demand type:\n\/\/ randomised demand for a priority 1 service. Resources are allocated to meet this demand for priority 1, and spare resource can\n\/\/ be used for a priority 2 service.\n\/\/\n\/\/ These demand type examples have been chosen purely for simplicity of demonstration.

For example:\n<\/p>\n\n<pre>\n  &lt;object type=\"image\/svg+xml\" data=\"https:\/\/dot.skia.org\/dot?first-diagram\">&lt;\/object>\n\n  ...\n\n  &lt;object type=\"image\/svg+xml\" data=\"https:\/\/dot.skia.org\/dot?second-diagram\">&lt;\/object>\n<\/pre>\n\n<p>\n\tThe service understands the following formats:\n<\/p>\n<ul>\n  <li>dot<\/li>\n  <li>neato<\/li>\n  <li>twopi<\/li>\n  <li>circo<\/li>\n  <li>fdp<\/li>\n  <li>sfdp<\/li>\n<\/ul>\n\n<p>The format is specified via the path in the URL, for example to use neato:<\/p>\n\n<pre>&lt;details>\n&lt;summary>\n  &lt;object type=\"image\/svg+xml\" data=\"https:\/\/dot.skia.org\/neato\">&lt;\/object>\n&lt;\/summary>\n&lt;pre>\n  graph {\n\t  Hello -- World\n  }\n&lt;\/pre>\n&lt;\/details><\/pre>\n\n<\/body>\n`))\n\tif err != nil {\n\t\tsklog.Errorf(\"Failed to render index page: %s\", err)\n\t}\n}\n\nfunc transformToSVG(ctx context.Context, format, dotCode string) (string, error) {\n\tcmd := exec.CommandContext(ctx, format, \"-Tsvg\")\n\tstdin, err := cmd.StdinPipe()\n\tif err != nil {\n\t\treturn \"\", fmt.Errorf(\"Failed to create stdin pipe to dot: %s\", err)\n\t}\n\n\tgo func() {\n\t\tif _, err := io.WriteString(stdin, dotCode); err != nil {\n\t\t\t_ = stdin.Close()\n\t\t\tsklog.Errorf(\"Failed to write to dot stdin: %s\", err)\n\t\t\treturn\n\t\t}\n\t\tif err := stdin.Close(); err != nil {\n\t\t\tsklog.Errorf(\"Failed to close dot stdin: %s\", err)\n\t\t}\n\t}()\n\n\tout, err := cmd.CombinedOutput()\n\treturn string(out), err\n}\n\nfunc (srv *server) transformHandler(w http.ResponseWriter, r *http.Request) {\n\t\/\/ Strip off leading slash from path.\n\tformat := r.URL.Path[1:]\n\n\tif !util.In(format, validFormats) {\n\t\thttputils.ReportError(w, fmt.Errorf(\"Unknown format: %q\", format), \"Unknown format.\", http.StatusNotFound)\n\t\treturn\n\t}\n\n\tsourceURL := r.Header.Get(\"Referer\")\n\tif sourceURL == \"\" {\n\t\thttputils.ReportError(w, fmt.Errorf(\"Missing Referer header.\"), \"Missing Referer header.\", http.StatusNotFound)\n\t\treturn\n\t}\n\n\tif !srv.allowed.MatchString(sourceURL) {\n\t\thttputils.ReportError(w, fmt.Errorf(\"Not an allowed domain: %q\", sourceURL), \"Not an allowed domain.\", http.StatusNotFound)\n\t\treturn\n\t}\n\n\t\/\/ Load the HTML document\n\tresp, err := srv.client.Get(sourceURL)\n\tif err != nil {\n\t\thttputils.ReportError(w, fmt.Errorf(\"Failed to fetch referring page: %s\", err), \"Failed to fetch referring page.\", http.StatusNotFound)\n\t\treturn\n\t}\n\tdefer util.Close(resp.Body)\n\tif resp.StatusCode != 200 {\n\t\thttputils.ReportError(w, fmt.Errorf(\"Failed to get 200 fetching referring page: %d\", resp.StatusCode), \"Failed to get 200 fetching referring page.\", http.StatusNotFound)\n\t\treturn\n\t}\n\n\t\/\/ NOTE: If the service is too slow them implement caching by using md5\n\t\/\/ along with an lru in-memory cache.

You will need to ensure that you have a version of the code\n\/\/ generator installed that corresponds to the vendored runtime package,\n\/\/ otherwise the generated code may be incompatible.\n\/\/\n\/\/ TODO: Can this script compile the protoc-gen-gogo binary directly from the\n\/\/ vendor directory (into a temporary directory) and add it to the path of the\n\/\/ protoc executable? That would remove the need for manually keeping the\n\/\/ generator installation in sync with the runtime that's vendored.\n\nimport (\n\t\"fmt\"\n\t\"os\"\n\t\"os\/exec\"\n\t\"path\/filepath\"\n\t\"runtime\"\n\n\t\"github.com\/pkg\/errors\"\n\n\t\"github.com\/havoc-io\/mutagen\/cmd\"\n)\n\nvar subdirectories = []struct {\n\tpath  string\n\tfiles []string\n}{\n\t{\"session\", []string{\"session.proto\"}},\n\t{\"sync\", []string{\"cache.proto\", \"entry.proto\"}},\n\t{\"url\", []string{\"url.proto\"}},\n}\n\nfunc main() {\n\t\/\/ Compute the path to the Mutagen source directory.\n\t_, file, _, ok := runtime.Caller(0)\n\tif !ok {\n\t\tcmd.Fatal(errors.New(\"unable to compute script path\"))\n\t}\n\tmutagenSource := filepath.Dir(filepath.Dir(file))\n\n\t\/\/ Compute the vendoring path.\n\tvendor := filepath.Join(mutagenSource, \"vendor\")\n\n\t\/\/ Compute the GOPATH src directory.\n\tgopathSrc := filepath.Dir(filepath.Dir(filepath.Dir(mutagenSource)))\n\n\t\/\/ Process subdirectories.\n\tfor _, s := range subdirectories {\n\t\t\/\/ Compute the subdirectory path.\n\t\tsubdirectory := filepath.Join(mutagenSource, s.path)\n\n\t\t\/\/ Print directory information.\n\t\tfmt.Println(\"Processing\", subdirectory)\n\n\t\t\/\/ Execute the Protocol Buffers compiler using the gogo generator.\n\t\t\/\/ HACK: We specify include paths so that we can reference definitions\n\t\t\/\/ between packages, but this means that we also end up needing to\n\t\t\/\/ specify -I., because for some reason the Protocol Buffers compiler is\n\t\t\/\/ too stupid to include this automatically.

Integers are printed unsigned if they have unsigned type.\n\tSimilarly, there is no need to specify the size of the operand (int8, int64).\n\n\tThe width and precision control formatting and are in units of Unicode\n\tcode points.  (This differs from C's printf where the units are numbers\n\tof bytes.) Either or both of the flags may be replaced with the\n\tcharacter '*', causing their values to be obtained from the next\n\toperand, which must be of type int.\n\n\tFor numeric values, width sets the minimum width of the field and\n\tprecision sets the number of places after the decimal, if appropriate,\n\texcept that for %g\/%G it sets the total number of digits. For example,\n\tgiven 123.45 the format %6.2f prints 123.45 while %.4g prints 123.5.\n\tThe default precision for %e and %f is 6; for %g it is the smallest\n\tnumber of digits necessary to identify the value uniquely.\n\n\tFor most values, width is the minimum number of characters to output,\n\tpadding the formatted form with spaces if necessary.\n\tFor strings, precision is the maximum number of characters to output,\n\ttruncating if necessary.\n\n\tOther flags:\n\t\t+\talways print a sign for numeric values;\n\t\t\tguarantee ASCII-only output for %q (%+q)\n\t\t-\tpad with spaces on the right rather than the left (left-justify the field)\n\t\t#\talternate format: add leading 0 for octal (%#o), 0x for hex (%#x);\n\t\t\t0X for hex (%#X); suppress 0x for %p (%#p);\n\t\t\tfor %q, print a raw (backquoted) string if strconv.CanBackquote\n\t\t\treturns true;\n\t\t\twrite e.g. U+0078 'x' if the character is printable for %U (%#U).\n\t\t' '\t(space) leave a space for elided sign in numbers (% d);\n\t\t\tput spaces between bytes printing strings or slices in hex (% x, % X)\n\t\t0\tpad with leading zeros rather than spaces;\n\t\t\tfor numbers, this moves the padding after the sign\n\n\tFlags are ignored by verbs that do not expect them.\n\tFor example there is no alternate decimal format, so %#d and %d\n\tbehave identically.\n\n\tFor each Printf-like function, there is also a Print function\n\tthat takes no format and is equivalent to saying %v for every\n\toperand.  Another variant Println inserts blanks between\n\toperands and appends a newline.\n\n\tRegardless of the verb, if an operand is an interface value,\n\tthe internal concrete value is used, not the interface itself.\n\tThus:\n\t\tvar i interface{} = 23\n\t\tfmt.Printf(\"%v\\n\", i)\n\twill print 23.\n\n\tIf an operand implements interface Formatter, that interface\n\tcan be used for fine control of formatting.\n\n\tIf the format (which is implicitly %v for Println etc.) is valid\n\tfor a string (%s %q %v %x %X), the following two rules also apply:\n\n\t1.

Integers are printed unsigned if they have unsigned type.\n\tSimilarly, there is no need to specify the size of the operand (int8, int64).\n\n\tWidth is specified by an optional decimal number immediately following the verb.\n\tIf absent, the width is whatever is necessary to represent the value.\n\tPrecision is specified after the (optional) width by a period followed by a\n\tdecimal number. If no period is present, a default precision is used.\n\tA period with no following number specifies a precision of zero.\n\tExamples:\n\t\t%f:    default width, default precision\n\t\t%9f    width 9, default precision\n\t\t%.2f   default width, precision 2\n\t\t%9.2f  width 9, precision 2\n\t\t%9.f   width 9, precision 0\n\n\tWidth and precision are measured in units of Unicode code points.\n\t(This differs from C's printf where the units are numbers\n\tof bytes.) Either or both of the flags may be replaced with the\n\tcharacter '*', causing their values to be obtained from the next\n\toperand, which must be of type int.\n\n\tFor most values, width is the minimum number of characters to output,\n\tpadding the formatted form with spaces if necessary.\n\tFor strings, precision is the maximum number of characters to output,\n\ttruncating if necessary.\n\n\tFor floating-point values, width sets the minimum width of the field and\n\tprecision sets the number of places after the decimal, if appropriate,\n\texcept that for %g\/%G it sets the total number of digits. For example,\n\tgiven 123.45 the format %6.2f prints 123.45 while %.4g prints 123.5.\n\tThe default precision for %e and %f is 6; for %g it is the smallest\n\tnumber of digits necessary to identify the value uniquely.\n\n\tFor complex numbers, the width and precision apply to the two\n\tcomponents independently and the result is parenthsized, so %f applied\n\tto 1.2+3.4i produces (1.200000+3.400000i).\n\n\tOther flags:\n\t\t+\talways print a sign for numeric values;\n\t\t\tguarantee ASCII-only output for %q (%+q)\n\t\t-\tpad with spaces on the right rather than the left (left-justify the field)\n\t\t#\talternate format: add leading 0 for octal (%#o), 0x for hex (%#x);\n\t\t\t0X for hex (%#X); suppress 0x for %p (%#p);\n\t\t\tfor %q, print a raw (backquoted) string if strconv.CanBackquote\n\t\t\treturns true;\n\t\t\twrite e.g. U+0078 'x' if the character is printable for %U (%#U).\n\t\t' '\t(space) leave a space for elided sign in numbers (% d);\n\t\t\tput spaces between bytes printing strings or slices in hex (% x, % X)\n\t\t0\tpad with leading zeros rather than spaces;\n\t\t\tfor numbers, this moves the padding after the sign\n\n\tFlags are ignored by verbs that do not expect them.\n\tFor example there is no alternate decimal format, so %#d and %d\n\tbehave identically.\n\n\tFor each Printf-like function, there is also a Print function\n\tthat takes no format and is equivalent to saying %v for every\n\toperand.  Another variant Println inserts blanks between\n\toperands and appends a newline.\n\n\tRegardless of the verb, if an operand is an interface value,\n\tthe internal concrete value is used, not the interface itself.\n\tThus:\n\t\tvar i interface{} = 23\n\t\tfmt.Printf(\"%v\\n\", i)\n\twill print 23.\n\n\tIf an operand implements interface Formatter, that interface\n\tcan be used for fine control of formatting.\n\n\tIf the format (which is implicitly %v for Println etc.) is valid\n\tfor a string (%s %q %v %x %X), the following two rules also apply:\n\n\t1. If an operand implements the error interface, the Error method\n\twill be used to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\t2. If an operand implements method String() string, that method\n\twill be used to convert the object to a string, which will then\n\tbe formatted as required by the verb (if any).\n\n\tTo avoid recursion in cases such as\n\t\ttype X string\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", x) }\n\tconvert the value before recurring:\n\t\tfunc (x X) String() string { return Sprintf(\"<%s>\", string(x)) }\n\n\tExplicit argument indexes:\n\n\tIn Printf, Sprintf, and Fprintf, the default behavior is for each\n\tformatting verb to format successive arguments passed in the call.\n\tHowever, the notation [n] immediately before the verb indicates that the\n\tnth one-indexed argument is to be formatted instead.

For\n\/\/ example:\n\/\/\n\/\/     RegisterOption(\"allow-empty\", func(value interface{}, optionValue string) (interface{}, error) {\n\/\/         if optionValue == \"false\" {\n\/\/             if value == nil || value.(string) == \"\" {\n\/\/                 return nil, errors.New(\"Cannot be empty\")\n\/\/             }\n\/\/         }\n\/\/         return value, nil\n\/\/     })\n\/\/\n\/\/     type Example struct {\n\/\/         Name `request:\",allow-empty=false\"`\n\/\/     }\n\/\/\n\/\/ Any options without a value (e.g. request:\",non-empty\") will have\n\/\/ their value set to \"true\".\n\/\/\n\/\/ An error will be returned if an OptionFunc is already registered\n\/\/ for the provided name.\nfunc RegisterOption(name string, optionFunc OptionFunc) error {\n\tif _, ok := registeredOptions[name]; ok {\n\t\treturn fmt.Errorf(`An OptionFunc is already registered for \"%s\"`, name)\n\t}\n\tregisteredOptions[name] = optionFunc\n\treturn nil\n}\n\n\/\/ ApplyOptions will attempt to apply any OptionFunc values registered\n\/\/ with RegisterOption to a struct field.
