This puts backups in an odd position,\nparticularly with regard to the storage of backup metadata and\narchives.  As a result, here are a couple concerns worth mentioning.\n\nFirst, as noted above backup is about state but not a part of state.\nSo exposing backup-related methods on State would imply the wrong\nthing.  Thus the backup functionality here in the state package (not\nstate\/backups) is exposed as functions to which you pass a state\nobject.\n\nSecond, backup creates an archive file containing a dump of state's\nmongo DB.  Storing backup metadata\/archives in mongo is thus a\nsomewhat circular proposition that has the potential to cause\nproblems.  That may need further attention.\n\nNote that state (and juju as a whole) currently does not have a\npersistence layer abstraction to facilitate separating different\npersistence needs and implementations.  As a consequence, state's\ndata, whether about how an environment should look or about existing\nresources within an environment, is dumped essentially straight into\nState's mongo connection.  The code in the state package does not\nmake any distinction between the two (nor does the package clearly\ndistinguish between state-related abstractions and state-related\ndata).\n\nBackup adds yet another category, merely taking advantage of\nState's DB.  In the interest of making the distinction clear, the\ncode that directly interacts with State (and its DB) lives in this\nfile.  As mentioned previously, the functionality here is exposed\nthrough functions that take State, rather than as methods on State.\nFurthermore, the bulk of the backup-related code, which does not need\ndirect interaction with State, lives in the state\/backups package.\n*\/\n\n\/\/ backupMetadataDoc is a mirror of metadata.Metadata, used just for DB storage.\ntype backupMetadataDoc struct {\n\tID             string `bson:\"_id\"`\n\tStarted        int64  `bson:\"started,minsize\"`\n\tFinished       int64  `bson:\"finished,minsize\"`\n\tChecksum       string `bson:\"checksum\"`\n\tChecksumFormat string `bson:\"checksumformat\"`\n\tSize           int64  `bson:\"size,minsize\"`\n\tStored         bool   `bson:\"stored\"`\n\tNotes          string `bson:\"notes,omitempty\"`\n\n\t\/\/ origin\n\tEnvironment string         `bson:\"environment\"`\n\tMachine     string         `bson:\"machine\"`\n\tHostname    string         `bson:\"hostname\"`\n\tVersion     version.Number `bson:\"version\"`\n}\n\nfunc (doc *backupMetadataDoc) fileSet() bool {\n\tif doc.Finished == 0 {\n\t\treturn false\n\t}\n\tif doc.Checksum == \"\" {\n\t\treturn false\n\t}\n\tif doc.ChecksumFormat == \"\" {\n\t\treturn false\n\t}\n\tif doc.Size == 0 {\n\t\treturn false\n\t}\n\treturn true\n}\n\nfunc (doc *backupMetadataDoc) validate() error {\n\tif doc.ID == \"\" {\n\t\treturn errors.New(\"missing ID\")\n\t}\n\tif doc.Started == 0 {\n\t\treturn errors.New(\"missing Started\")\n\t}\n\tif doc.Environment == \"\" {\n\t\treturn errors.New(\"missing Environment\")\n\t}\n\tif doc.Machine == \"\" {\n\t\treturn errors.New(\"missing Machine\")\n\t}\n\tif doc.Hostname == \"\" {\n\t\treturn errors.New(\"missing Hostname\")\n\t}\n\tif doc.Version.Major == 0 {\n\t\treturn errors.New(\"missing Version\")\n\t}\n\n\t\/\/ Check the file-related fields.\n\tif !doc.fileSet() {\n\t\tif doc.Stored {\n\t\t\treturn errors.New(`\"Stored\" flag is unexpectedly true`)\n\t\t}\n\t\t\/\/ Don't check the file-related fields.\n\t\treturn nil\n\t}\n\tif doc.Finished == 0 {\n\t\treturn errors.New(\"missing Finished\")\n\t}\n\tif doc.Checksum == \"\" {\n\t\treturn errors.New(\"missing Checksum\")\n\t}\n\tif doc.ChecksumFormat == \"\" {\n\t\treturn errors.New(\"missing ChecksumFormat\")\n\t}\n\tif doc.Size == 0 {\n\t\treturn errors.New(\"missing Size\")\n\t}\n\n\treturn nil\n}\n\n\/\/ asMetadata returns a new metadata.Metadata based on the backupMetadataDoc.\nfunc (doc *backupMetadataDoc) asMetadata() *metadata.Metadata {\n\t\/\/ Create a new Metadata.\n\torigin := metadata.ExistingOrigin(\n\t\tdoc.Environment,\n\t\tdoc.Machine,\n\t\tdoc.Hostname,\n\t\tdoc.Version,\n\t)\n\n\tstarted := time.Unix(doc.Started, 0).UTC()\n\tmeta := metadata.NewMetadata(\n\t\t*origin,\n\t\tdoc.Notes,\n\t\t&started,\n\t)\n\n\t\/\/ The ID is already set.\n\tmeta.SetID(doc.ID)\n\n\t\/\/ Exit early if file-related fields not set.\n\tif !doc.fileSet() {\n\t\treturn meta\n\t}\n\n\t\/\/ Set the file-related fields.\n\tvar finished *time.Time\n\tif doc.Finished != 0 {\n\t\tval := time.Unix(doc.Finished, 0).UTC()\n\t\tfinished = &val\n\t}\n\terr := meta.Finish(doc.Size, doc.Checksum, doc.ChecksumFormat, finished)\n\tif err != nil {\n\t\t\/\/ The doc should have already been validated.

This puts backups in an odd position,\nparticularly with regard to the storage of backup metadata and\narchives.  As a result, here are a couple concerns worth mentioning.\n\nFirst, as noted above backup is about state but not a part of state.\nSo exposing backup-related methods on State would imply the wrong\nthing.  Thus the backup functionality here in the state package (not\nstate\/backups) is exposed as functions to which you pass a state\nobject.\n\nSecond, backup creates an archive file containing a dump of state's\nmongo DB.  Storing backup metadata\/archives in mongo is thus a\nsomewhat circular proposition that has the potential to cause\nproblems.  That may need further attention.\n\nNote that state (and juju as a whole) currently does not have a\npersistence layer abstraction to facilitate separating different\npersistence needs and implementations.  As a consequence, state's\ndata, whether about how an environment should look or about existing\nresources within an environment, is dumped essentially straight into\nState's mongo connection.  The code in the state package does not\nmake any distinction between the two (nor does the package clearly\ndistinguish between state-related abstractions and state-related\ndata).\n\nBackup adds yet another category, merely taking advantage of\nState's DB.  In the interest of making the distinction clear, the\ncode that directly interacts with State (and its DB) lives in this\nfile.  As mentioned previously, the functionality here is exposed\nthrough functions that take State, rather than as methods on State.\nFurthermore, the bulk of the backup-related code, which does not need\ndirect interaction with State, lives in the state\/backups package.\n*\/\n\n\/\/ backupMetadataDoc is a mirror of metadata.Metadata, used just for DB storage.\ntype backupMetadataDoc struct {\n\tID             string `bson:\"_id\"`\n\tStarted        int64  `bson:\"started,minsize\"`\n\tFinished       int64  `bson:\"finished,minsize\"`\n\tChecksum       string `bson:\"checksum\"`\n\tChecksumFormat string `bson:\"checksumformat\"`\n\tSize           int64  `bson:\"size,minsize\"`\n\tStored         bool   `bson:\"stored\"`\n\tNotes          string `bson:\"notes,omitempty\"`\n\n\t\/\/ origin\n\tEnvironment string         `bson:\"environment\"`\n\tMachine     string         `bson:\"machine\"`\n\tHostname    string         `bson:\"hostname\"`\n\tVersion     version.Number `bson:\"version\"`\n}\n\nfunc (doc *backupMetadataDoc) fileSet() bool {\n\tif doc.Finished == 0 {\n\t\treturn false\n\t}\n\tif doc.Checksum == \"\" {\n\t\treturn false\n\t}\n\tif doc.ChecksumFormat == \"\" {\n\t\treturn false\n\t}\n\tif doc.Size == 0 {\n\t\treturn false\n\t}\n\treturn true\n}\n\nfunc (doc *backupMetadataDoc) validate() error {\n\tif doc.ID == \"\" {\n\t\treturn errors.New(\"missing ID\")\n\t}\n\tif doc.Started == 0 {\n\t\treturn errors.New(\"missing Started\")\n\t}\n\tif doc.Environment == \"\" {\n\t\treturn errors.New(\"missing Environment\")\n\t}\n\tif doc.Machine == \"\" {\n\t\treturn errors.New(\"missing Machine\")\n\t}\n\tif doc.Hostname == \"\" {\n\t\treturn errors.New(\"missing Hostname\")\n\t}\n\tif doc.Version.Major == 0 {\n\t\treturn errors.New(\"missing Version\")\n\t}\n\n\t\/\/ Check the file-related fields.\n\tif !doc.fileSet() {\n\t\tif doc.Stored {\n\t\t\treturn errors.New(`\"Stored\" flag is unexpectedly true`)\n\t\t}\n\t\t\/\/ Don't check the file-related fields.\n\t\treturn nil\n\t}\n\tif doc.Finished == 0 {\n\t\treturn errors.New(\"missing Finished\")\n\t}\n\tif doc.Checksum == \"\" {\n\t\treturn errors.New(\"missing Checksum\")\n\t}\n\tif doc.ChecksumFormat == \"\" {\n\t\treturn errors.New(\"missing ChecksumFormat\")\n\t}\n\tif doc.Size == 0 {\n\t\treturn errors.New(\"missing Size\")\n\t}\n\n\treturn nil\n}\n\n\/\/ asMetadata returns a new metadata.Metadata based on the backupMetadataDoc.\nfunc (doc *backupMetadataDoc) asMetadata() *metadata.Metadata {\n\t\/\/ Create a new Metadata.\n\torigin := metadata.ExistingOrigin(\n\t\tdoc.Environment,\n\t\tdoc.Machine,\n\t\tdoc.Hostname,\n\t\tdoc.Version,\n\t)\n\n\tstarted := time.Unix(doc.Started, 0).UTC()\n\tmeta := metadata.NewMetadata(\n\t\t*origin,\n\t\tdoc.Notes,\n\t\t&started,\n\t)\n\n\t\/\/ The ID is already set.\n\tmeta.SetID(doc.ID)\n\n\t\/\/ Exit early if file-related fields not set.\n\tif !doc.fileSet() {\n\t\treturn meta\n\t}\n\n\t\/\/ Set the file-related fields.\n\tvar finished *time.Time\n\tif doc.Finished != 0 {\n\t\tval := time.Unix(doc.Finished, 0).UTC()\n\t\tfinished = &val\n\t}\n\terr := meta.Finish(doc.Size, doc.Checksum, doc.ChecksumFormat, finished)\n\tif err != nil {\n\t\t\/\/ The doc should have already been validated.

This behaviour is optional, Datastore can be disabled completely.\nYou can also choose whether saving to Datastore happens synchronously (in the same goroutine)\nor asynchronously (in another goroutine).\n\nLimitations based on GAE Memcache:\n\n- Since session ids are used in the Memcache keys, session ids can't be longer than 250 chars (bytes, but with Base64 charset it's the same).\nIf you also specify a key prefix (in MemcacheStoreOptions), that also counts into it.\n\n- The size of a Session cannot be larger than 1 MB (marshalled into a byte slice).\n\nNote that the Store will automatically \"flush\" sessions accessed from it when the Store is closed,\nso it is very important to close the Store at the end of your request; this is usually done by closing\nthe session manager to which you passed the store (preferably with the defer statement).\n\nCheck out the GAE session demo application which shows how to use it properly:\n\nhttps:\/\/github.com\/icza\/session\/blob\/master\/gae_session_demo\/session_demo.go\n\n*\/\n\npackage session\n\nimport (\n\t\"net\/http\"\n\t\"sync\"\n\t\"time\"\n\n\t\"appengine\"\n\t\"appengine\/datastore\"\n\t\"appengine\/memcache\"\n)\n\n\/\/ A Google App Engine Memcache session store implementation.\ntype memcacheStore struct {\n\tctx appengine.Context \/\/ Appengine context used when accessing the Memcache\n\n\tkeyPrefix string \/\/ Prefix to use in front of session ids to construct Memcache key\n\tretries   int    \/\/ Number of retries to perform in case of general Memcache failures\n\n\tcodec memcache.Codec \/\/ Codec used to marshal and unmarshal a Session to a byte slice\n\n\tonlyMemcache       bool   \/\/ Tells if sessions are not to be saved in Datastore\n\tasyncDatastoreSave bool   \/\/ Tells if saving in Datastore should happen asynchronously, in a new goroutine\n\tdsEntityName       string \/\/ Name of the datastore entity to use to save sessions\n\n\t\/\/ Map of sessions (mapped from ID) that were accessed using this store; usually it will only be 1.\n\t\/\/ It is also used as a cache, should the user call Get() with the same id multiple times.\n\tsessions map[string]Session\n\n\tmux *sync.RWMutex \/\/ mutex to synchronize access to sessions\n}\n\n\/\/ MemcacheStoreOptions defines options that may be passed when creating a new Memcache session store.\n\/\/ All fields are optional; default value will be used for any field that has the zero value.\ntype MemcacheStoreOptions struct {\n\t\/\/ Prefix to use when storing sessions in the Memcache, cannot contain a null byte\n\t\/\/ and cannot be longer than 250 chars (bytes) when concatenated with the session id; default value is the empty string\n\t\/\/ The Memcache key will be this prefix and the session id concatenated.\n\tKeyPrefix string\n\n\t\/\/ Number of retries to perform if Memcache operations fail due to general service error;\n\t\/\/ default value is 3\n\tRetries int\n\n\t\/\/ Codec used to marshal and unmarshal a Session to a byte slice;\n\t\/\/ Default value is &memcache.Gob (which uses the gob package).\n\tCodec *memcache.Codec\n\n\t\/\/ Tells if sessions are only to be stored in Memcache, and do not store them in Datastore as backup;\n\t\/\/ as Memcache has no guarantees, it may lose content from time to time, but if Datastore is\n\t\/\/ also used, the session will automatically be retrieved from the Datastore if not found in Memcache;\n\t\/\/ default value is false (which means to also save sessions in the Datastore)\n\tOnlyMemcache bool\n\n\t\/\/ Tells if saving in Datastore should happen asynchronously (in a new goroutine, possibly after returning),\n\t\/\/ if false, session saving in Datastore will happen in the same goroutine, before returning from the request.\n\t\/\/ Asynchronous saving gives smaller latency (and is enough most of the time as Memcache is always checked first);\n\t\/\/ default value is false which means to save sessions in the Datastore in the same goroutine, synchronously\n\t\/\/ Not used if OnlyMemcache=true.\n\t\/\/ FIXME: See https:\/\/github.com\/icza\/session\/issues\/3\n\tAsyncDatastoreSave bool\n\n\t\/\/ Name of the entity to use for saving sessions;\n\t\/\/ default value is \"sess_\"\n\t\/\/ Not used if OnlyMemcache=true.\n\tDSEntityName string\n}\n\n\/\/ SessEntity models the session entity saved to Datastore.\n\/\/ The Key is the session id.\ntype SessEntity struct {\n\tExpires time.Time `datastore:\"exp\"`\n\tValue   []byte    `datastore:\"val\"`\n}\n\n\/\/ Pointer to zero value of MemcacheStoreOptions to be reused for efficiency.\nvar zeroMemcacheStoreOptions = new(MemcacheStoreOptions)\n\n\/\/ NewMemcacheStore returns a new, GAE Memcache session Store with default options.\n\/\/ Default values of options are listed in the MemcacheStoreOptions type.\n\/\/\n\/\/ Important!

The format is designed for testing\n\/\/ purposes by aiding a human in the manual scripting of compression stream\n\/\/ from individual bit-strings. It is designed to be relatively succinct, but\n\/\/ allow the user to have control over the bit-order and also to allow the\n\/\/ presence of comments to encode authorial intent.\n\/\/\n\/\/ The format consists of a series of tokens separated by white space of any\n\/\/ kind. The '#' character is used for commenting. Thus, any bytes on a given\n\/\/ line that appear after the '#' character is ignored.\n\/\/\n\/\/ The first valid token must either be a \"<<<\" (little-endian) or a \">>>\"\n\/\/ (big-endian). This determines whether the preceding bits in the stream are\n\/\/ packed starting with the least-significant bits of a byte (little-endian) or\n\/\/ packed starting with the most-significant bits of a byte (big-endian).\n\/\/ Formats like DEFLATE and Brotli use little-endian, while BZip2 uses a\n\/\/ big-endian bit-packing mode. This token appears exactly once at the start.\n\/\/\n\/\/ A token of the form \"<\" (little-endian) or \">\" (big-endian) determines the\n\/\/ current bit-parsing mode, which alters the way subsequent tokens are\n\/\/ processed. The format defaults to using a little-endian bit-parsing mode.\n\/\/\n\/\/ A token of the pattern \"[01]{1,64}\" forms a bit-string (e.g. 11010).\n\/\/ If the current bit-parsing mode is little-endian, then the right-most bits of\n\/\/ the bit-string are written first to the resulting bit-stream. Likewise, if\n\/\/ the bit-parsing mode is big-endian, then the left-most bits of the bit-string\n\/\/ are written first to the resulting bit-stream.\n\/\/\n\/\/ A token of the pattern \"D[0-9]+:[0-9]+\" or \"H[0-9]+:[0-9a-fA-F]{1,16}\"\n\/\/ represents either a decimal value or a hexadecimal value, respectively.\n\/\/ This numeric value is converted to the unsigned binary representation and\n\/\/ used as the bit-string to write. The first number indicates the bit-length\n\/\/ of the bit-string and must be between 0 and 64 bits. The second number\n\/\/ represents the numeric value. The bit-length must be long enough to contain\n\/\/ the resulting binary value. If the current bit-parsing mode is little-endian,\n\/\/ then the least-significant bits of this binary number are written first to\n\/\/ the resulting bit-stream. Likewise, the opposite holds for big-endian mode.\n\/\/\n\/\/ A token that is of the pattern \"X:[0-9a-fA-F]+\" represents literal bytes in\n\/\/ hexadecimal format that should be written to the resulting bit-stream.\n\/\/ This token is affected by neither the bit-packing nor the bit-parsing modes.\n\/\/ However, it may only be used when the bit-stream is already byte-aligned.\n\/\/\n\/\/ A token decorator of \"<\" (little-endian) or \">\" (big-endian) may begin\n\/\/ any binary token or decimal token. This will affect the bit-parsing mode\n\/\/ for that token only. It will not set the overall global mode. That still\n\/\/ needs to be done by standalone \"<\" and \">\" tokens. This decorator has no\n\/\/ effect if applied to the literal bytes token.\n\/\/\n\/\/ A token decorator of the pattern \"[*][0-9]+\" may trail any token. This is\n\/\/ a quantifier decorator which indicates that the current token is to be\n\/\/ repeated some number of times. It is used to quickly replicate data and\n\/\/ allows the format to quickly generate large quantities of data.\n\/\/\n\/\/ If the total bit-stream does not end on a byte-aligned edge, then the stream\n\/\/ will automatically be padded up to the nearest byte with 0 bits.\n\/\/\n\/\/ Example BitGen file:\n\/\/\t<<< # DEFLATE uses LE bit-packing order\n\/\/\n\/\/\t< 0 00 0*5                 # Non-last, raw block, padding\n\/\/\t< H16:0004 H16:fffb        # RawSize: 4\n\/\/\tX:deadcafe                 # Raw data\n\/\/\n\/\/\t< 1 10                     # Last, dynamic block\n\/\/\t< D5:1 D5:0 D4:15          # HLit: 258, HDist: 1, HCLen: 19\n\/\/\t< 000*3 001 000*13 001 000 # HCLens: {0:1, 1:1}\n\/\/\t> 0*256 1*2                # HLits: {256:1, 257:1}\n\/\/\t> 0                        # HDists: {}\n\/\/\t> 1 0                      # Use invalid HDist code 0\n\/\/\n\/\/ Generated output stream (in hexadecimal):\n\/\/\t\"000400fbffdeadcafe0de0010400000000100000000000000000000000000000\" +\n\/\/\t\"0000000000000000000000000000000000002c\"\nfunc DecodeBitGen(str string) ([]byte, error) {\n\t\/\/ Tokenize the input string by removing comments and superfluous spaces.\n\tvar toks []string\n\tfor _, s := range strings.Split(str, \"\\n\") {\n\t\tif i := strings.IndexByte(s, '#');

The bit-length must be long enough to contain\n\/\/ the resulting binary value. If the current bit-parsing mode is little-endian,\n\/\/ then the least-significant bits of this binary number are written first to\n\/\/ the resulting bit-stream. Likewise, the opposite holds for big-endian mode.\n\/\/\n\/\/ A token that is of the pattern \"X:[0-9a-fA-F]+\" represents literal bytes in\n\/\/ hexadecimal format that should be written to the resulting bit-stream.\n\/\/ This token is affected by neither the bit-packing nor the bit-parsing modes.\n\/\/ However, it may only be used when the bit-stream is already byte-aligned.\n\/\/\n\/\/ A token decorator of \"<\" (little-endian) or \">\" (big-endian) may begin\n\/\/ any binary token or decimal token. This will affect the bit-parsing mode\n\/\/ for that token only. It will not set the overall global mode. That still\n\/\/ needs to be done by standalone \"<\" and \">\" tokens. This decorator has no\n\/\/ effect if applied to the literal bytes token.\n\/\/\n\/\/ A token decorator of the pattern \"[*][0-9]+\" may trail any token. This is\n\/\/ a quantifier decorator which indicates that the current token is to be\n\/\/ repeated some number of times. It is used to quickly replicate data and\n\/\/ allows the format to quickly generate large quantities of data.\n\/\/\n\/\/ If the total bit-stream does not end on a byte-aligned edge, then the stream\n\/\/ will automatically be padded up to the nearest byte with 0 bits.\n\/\/\n\/\/ Example BitGen file:\n\/\/\t<<< # DEFLATE uses LE bit-packing order\n\/\/\n\/\/\t< 0 00 0*5                 # Non-last, raw block, padding\n\/\/\t< H16:0004 H16:fffb        # RawSize: 4\n\/\/\tX:deadcafe                 # Raw data\n\/\/\n\/\/\t< 1 10                     # Last, dynamic block\n\/\/\t< D5:1 D5:0 D4:15          # HLit: 258, HDist: 1, HCLen: 19\n\/\/\t< 000*3 001 000*13 001 000 # HCLens: {0:1, 1:1}\n\/\/\t> 0*256 1*2                # HLits: {256:1, 257:1}\n\/\/\t> 0                        # HDists: {}\n\/\/\t> 1 0                      # Use invalid HDist code 0\n\/\/\n\/\/ Generated output stream (in hexadecimal):\n\/\/\t\"000400fbffdeadcafe0de0010400000000100000000000000000000000000000\" +\n\/\/\t\"0000000000000000000000000000000000002c\"\nfunc DecodeBitGen(str string) ([]byte, error) {\n\t\/\/ Tokenize the input string by removing comments and superfluous spaces.\n\tvar toks []string\n\tfor _, s := range strings.Split(str, \"\\n\") {\n\t\tif i := strings.IndexByte(s, '#');

A server registers an object, making it visible\n\tas a service with the name of the type of the object.  After registration, public\n\tmethods of the object will be accessible remotely.  A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn.  More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection.  The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection).  The resulting\n\tClient object has two methods, Call and Go, that specify the service and method to\n\tcall, a structure containing the arguments, and a structure to receive the result\n\tparameters.\n\n\tCall waits for the remote call to complete; Go launches the call asynchronously\n\tand returns a channel that will signal completion.\n\n\tPackage \"gob\" is used to transport the data.\n\n\tHere is a simple example.  A server wishes to export an object of type Arith:\n\n\t\tpackage server\n\n\t\ttype Args struct {\n\t\t\tA, B int\n\t\t}\n\n\t\ttype Reply struct {\n\t\t\tC int\n\t\t}\n\n\t\ttype Arith int\n\n\t\tfunc (t *Arith) Multiply(args *Args, reply *Reply) os.Error {\n\t\t\treply.C = args.A * args.B;\n\t\t\treturn nil\n\t\t}\n\n\t\tfunc (t *Arith) Divide(args *Args, reply *Reply) os.Error {\n\t\t\tif args.B == 0 {\n\t\t\t\treturn os.ErrorString(\"divide by zero\");\n\t\t\t}\n\t\t\treply.C = args.A \/ args.B;\n\t\t\treturn nil\n\t\t}\n\n\tThe server calls (for HTTP service):\n\n\t\tarith := new(Arith);\n\t\trpc.Register(arith);\n\t\trpc.HandleHTTP();\n\t\tl, e := net.Listen(\"tcp\", \":1234\");\n\t\tif e != nil {\n\t\t\tlog.Exit(\"listen error:\", e);\n\t\t}\n\t\tgo http.Serve(l, nil);\n\n\tAt this point, clients can see a service \"Arith\" with methods \"Arith.Multiply\" and\n\t\"Arith.Divide\".  To invoke one, a client first dials the server:\n\n\t\tclient, err := rpc.DialHTTP(\"tcp\", serverAddress + \":1234\");\n\t\tif err != nil {\n\t\t\tlog.Exit(\"dialing:\", err);\n\t\t}\n\n\tThen it can make a remote call:\n\n\t\t\/\/ Synchronous call\n\t\targs := &server.Args{7,8};\n\t\treply := new(server.Reply);\n\t\terr = client.Call(\"Arith.Multiply\", args, reply);\n\t\tif err != nil {\n\t\t\tlog.Exit(\"arith error:\", err);\n\t\t}\n\t\tfmt.Printf(\"Arith: %d*%d=%d\", args.A, args.B, reply.C);\n\n\tor\n\n\t\t\/\/ Asynchronous call\n\t\tdivCall := client.Go(\"Arith.Divide\", args, reply, nil);\n\t\treplyCall := <-divCall.Done;\t\/\/ will be equal to divCall\n\t\t\/\/ check errors, print, etc.\n\n\tA server implementation will often provide a simple, type-safe wrapper for the\n\tclient.\n*\/\npackage rpc\n\nimport (\n\t\"gob\"\n\t\"http\"\n\t\"log\"\n\t\"io\"\n\t\"net\"\n\t\"os\"\n\t\"reflect\"\n\t\"strings\"\n\t\"sync\"\n\t\"unicode\"\n\t\"utf8\"\n)\n\n\/\/ Precompute the reflect type for os.Error.

A server registers an object, making it visible\n\tas a service with the name of the type of the object.  After registration, public\n\tmethods of the object will be accessible remotely.  A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn.  More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection.  The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection).  The resulting\n\tClient object has two methods, Call and Go, that specify the service and method to\n\tcall, a structure containing the arguments, and a structure to receive the result\n\tparameters.\n\n\tCall waits for the remote call to complete; Go launches the call asynchronously\n\tand returns a channel that will signal completion.\n\n\tPackage \"gob\" is used to transport the data.\n\n\tHere is a simple example.  A server wishes to export an object of type Arith:\n\n\t\tpackage server\n\n\t\ttype Args struct {\n\t\t\tA, B int\n\t\t}\n\n\t\ttype Reply struct {\n\t\t\tC int\n\t\t}\n\n\t\ttype Arith int\n\n\t\tfunc (t *Arith) Multiply(args *Args, reply *Reply) os.Error {\n\t\t\treply.C = args.A * args.B\n\t\t\treturn nil\n\t\t}\n\n\t\tfunc (t *Arith) Divide(args *Args, reply *Reply) os.Error {\n\t\t\tif args.B == 0 {\n\t\t\t\treturn os.ErrorString(\"divide by zero\")\n\t\t\t}\n\t\t\treply.C = args.A \/ args.B\n\t\t\treturn nil\n\t\t}\n\n\tThe server calls (for HTTP service):\n\n\t\tarith := new(Arith)\n\t\trpc.Register(arith)\n\t\trpc.HandleHTTP()\n\t\tl, e := net.Listen(\"tcp\", \":1234\")\n\t\tif e != nil {\n\t\t\tlog.Exit(\"listen error:\", e)\n\t\t}\n\t\tgo http.Serve(l, nil)\n\n\tAt this point, clients can see a service \"Arith\" with methods \"Arith.Multiply\" and\n\t\"Arith.Divide\".  To invoke one, a client first dials the server:\n\n\t\tclient, err := rpc.DialHTTP(\"tcp\", serverAddress + \":1234\")\n\t\tif err != nil {\n\t\t\tlog.Exit(\"dialing:\", err)\n\t\t}\n\n\tThen it can make a remote call:\n\n\t\t\/\/ Synchronous call\n\t\targs := &server.Args{7,8}\n\t\treply := new(server.Reply)\n\t\terr = client.Call(\"Arith.Multiply\", args, reply)\n\t\tif err != nil {\n\t\t\tlog.Exit(\"arith error:\", err)\n\t\t}\n\t\tfmt.Printf(\"Arith: %d*%d=%d\", args.A, args.B, reply.C)\n\n\tor\n\n\t\t\/\/ Asynchronous call\n\t\tdivCall := client.Go(\"Arith.Divide\", args, reply, nil)\n\t\treplyCall := <-divCall.Done\t\/\/ will be equal to divCall\n\t\t\/\/ check errors, print, etc.\n\n\tA server implementation will often provide a simple, type-safe wrapper for the\n\tclient.\n*\/\npackage rpc\n\nimport (\n\t\"gob\"\n\t\"http\"\n\t\"log\"\n\t\"io\"\n\t\"net\"\n\t\"os\"\n\t\"reflect\"\n\t\"strings\"\n\t\"sync\"\n\t\"unicode\"\n\t\"utf8\"\n)\n\n\/\/ Precompute the reflect type for os.Error.

This ID is not\n\/\/ globally unique to keep it shorter for logging purposes.  It is\n\/\/ possible to have duplicates though very unlikely over the period\n\/\/ of a day or so.  It is a good idea to log the ID in any custom\n\/\/ log statements so that individual requests can easily be grepped\n\/\/ from busy log files.\n\/\/\n\/\/ Falcore collects performance statistics on every stage of the\n\/\/ pipeline.  The stats for the request are kept in PipelineStageStats.\n\/\/ This structure will only be complete in the Request passed to the\n\/\/ pipeline RequestDoneCallback.  Overhead will only be available in\n\/\/ the RequestDoneCallback and it's the difference between the total\n\/\/ request time and the sums of the stage times.

and not depend on a working connection to a remote MDQ server.\n\n    It uses SQLite as it's datastore and allows lookup by either entityID or Location.\n    The latter is used by WAYF for it's mass hosting services BIRK and KRIB.\n\n    It can also be used as a library for just looking up metadata inside a go program.\n\n    Or a client can use the SQLite database directly using the following query:\n\n\t\t\"select e.md, e.hash from entity e, lookup l where l.hash = $1 and l.entity_id_fk = e.id and e.validuntil >= $2\"\n\n    where $1 is the lowercase hex sha1 of the entityID or location without the {sha1} prefix\n    $2 is the feed and $3 is the current epoch.\n\n    to-do:\n        - caching interface\n*\/\n\npackage lMDQ\n\nimport

{"text":"<commit_before>\/\/ Microscaling 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\/\/ Microscaling 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\/\/ Microscaling 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 microscaling 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 microscaling 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. Microscaling 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 microscaling that recognises only 1 demand type:\n\/\/ randomised demand for a priority 1 service. Resources are allocated to meet this demand for priority 1, and spare resource can\n\/\/ be used for a priority 2 service.\n\/\/\n\/\/ These demand type examples have been chosen purely for simplicity of demonstration. In the future more demand types\n\/\/ will be offered\npackage main\n\nimport

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\/\/ Microscaling 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\/\/ Microscaling 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 microscaling 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 microscaling 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. Microscaling 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 microscaling that recognises only 1 demand type:\n\/\/ randomised demand for a priority 1 service. Resources are allocated to meet this demand for priority 1, and spare resource can\n\/\/ be used for a priority 2 service.\n\/\/\n\/\/ These demand type examples have been chosen purely for simplicity of demonstration. In the future more demand types\n\/\/ will be offered\npackage main\n\nimport (\n\t\"os\"\n\t\"os\/signal\"\n\t\"sync\"\n\t\"syscall\"\n\t\"time\"\n\n\t\"github.com\/op\/go-logging\"\n\n\t\"github.com\/microscaling\/microscaling\/api\"\n\t\"github.com\/microscaling\/microscaling\/demand\"\n\t\"github.com\/microscaling\/microscaling\/scheduler\"\n)\n\nconst constSendMetricsSleep = 500 \/\/ milliseconds - delay before we send state on the metrics API\n\nvar (\n\tlog = logging.MustGetLogger(\"mssagent\")\n)\n\nfunc init() {\n\tinitLogging()\n}\n\ntype exitLock struct {\n\tready bool\n\tsync.Mutex\n}\n\nvar exitWhen exitLock\n\n\/\/ cleanup resets demand for all tasks to 0 before we quit\nfunc cleanup(s scheduler.Scheduler, running *demand.Tasks) {\n\trunning.Lock()\n\n\ttasks := running.Tasks\n\tfor name, task := range tasks {\n\t\ttask.Demand = 0\n\t\ttasks[name] = task\n\t}\n\n\trunning.Unlock()\n\n\tlog.Debugf(\"Reset tasks to 0 for cleanup\")\n\terr := s.StopStartTasks(tasks)\n\tif err != nil {\n\t\tlog.Errorf(\"Failed to cleanup tasks. %v\", err)\n\t}\n\n\texitWhen.Lock()\n\texitWhen.ready = true\n\texitWhen.Unlock()\n}\n\n\/\/ For this simple prototype, Microscaling sits in a loop checking for demand changes every X milliseconds\nfunc main() {\n\tvar err error\n\tvar tasks *demand.Tasks\n\n\tst := getSettings()\n\n\ts, err := getScheduler(st)\n\tif err != nil {\n\t\tlog.Errorf(\"Failed to get scheduler: %v\", err)\n\t\treturn\n\t}\n\n\ttasks = getTasks(st)\n\n\t\/\/ Let the scheduler know about the task types.\n\tfor name, task := range tasks.Tasks {\n\t\terr = s.InitScheduler(name, &task)\n\t\tif err != nil {\n\t\t\tlog.Errorf(\"Failed to start task %s: %v\", name, err)\n\t\t\treturn\n\t\t}\n\t}\n\n\t\/\/ Check if there are already any of these containers running\n\terr = s.CountAllTasks(tasks)\n\tif err != nil {\n\t\tlog.Errorf(\"Failed to count containers. %v\", err)\n\t}\n\n\t\/\/ Set the initial requested counts to match what's running\n\tfor name, task := range tasks.Tasks {\n\t\ttask.Requested = task.Running\n\t\ttasks.Tasks[name] = task\n\t}\n\n\t\/\/ Prepare for cleanup when we receive an interrupt\n\tclosedown := make(chan os.Signal, 1)\n\tsignal.Notify(closedown, os.Interrupt)\n\tsignal.Notify(closedown, syscall.SIGTERM)\n\n\t\/\/ Listen for demand on a websocket (we'll also use this to send metrics)\n\tdemandUpdate := make(chan []api.TaskDemand, 1)\n\tws, err := api.InitWebSocket()\n\tgo api.Listen(ws, demandUpdate)\n\n\t\/\/ Periodically send state to the API if required\n\tvar sendMetricsTimeout *time.Ticker\n\tif st.sendMetrics {\n\t\tsendMetricsTimeout = time.NewTicker(constSendMetricsSleep * time.Millisecond)\n\t\tgo func() {\n\t\t\tfor _ = range sendMetricsTimeout.C {\n\t\t\t\tlog.Debug(\"Sending metrics\")\n\t\t\t\t\/\/ Find out how many instances of each task are running\n\t\t\t\terr = s.CountAllTasks(tasks)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Errorf(\"Failed to count containers. %v\", err)\n\t\t\t\t}\n\n\t\t\t\terr = api.SendMetrics(ws, st.userID, tasks.Tasks)\n\t\t\t\tif err != nil {\n\t\t\t\t\tlog.Errorf(\"Failed to send metrics. %v\", err)\n\t\t\t\t}\n\n\t\t\t\texitWhen.Lock()\n\t\t\t\tif exitWhen.ready {\n\t\t\t\t\tif demand.Exited(tasks) {\n\t\t\t\t\t\tlog.Info(\"All finished\")\n\t\t\t\t\t\tos.Exit(1)\n\t\t\t\t\t}\n\t\t\t\t}\n\t\t\t\texitWhen.Unlock()\n\t\t\t}\n\t\t}()\n\t}\n\n\tgo func() {\n\t\tfor td := range demandUpdate {\n\t\t\tlog.Debug(\"Demand update\")\n\t\t\terr = handleDemandChange(td, s, tasks)\n\t\t\tif err != nil {\n\t\t\t\tlog.Errorf(\"Failed to handle demand change. %v\", err)\n\t\t\t}\n\t\t}\n\t}()\n\n\t<-closedown\n\tlog.Info(\"Clean up when ready\")\n\tclose(demandUpdate)\n\tcleanup(s, tasks)\n}\n<|endoftext|>"}

Only one type of the arguments may be specified: filenames,\n\t\tresources and names, or resources and label selector.\n\n\t\tSome resources, such as pods, support graceful deletion. These resources define a default period\n\t\tbefore they are forcibly terminated (the grace period) but you may override that value with\n\t\tthe --grace-period flag, or pass --now to set a grace-period of 1.

If your processes use shared storage or talk to a remote API and\n\t\tdepend on the name of the pod to identify themselves, force deleting those pods may result in\n\t\tmultiple processes running on different machines using the same identification which may lead\n\t\tto data corruption or inconsistency. Only force delete pods when you are sure the pod is\n\t\tterminated, or if your application can tolerate multiple copies of the same pod running at once.\n\t\tAlso, if you force delete pods the scheduler may place new pods on those nodes before the node\n\t\thas released those resources and causing those pods to be evicted immediately.\n\n\t\tNote that the delete command does NOT do resource version checks, so if someone\n\t\tsubmits an update to a resource right when you submit a delete, their update\n\t\twill be lost along with the rest of the resource.`)\n\n\tdelete_example = templates.Examples(`\n\t\t# Delete a pod using the type and name specified in pod.json.\n\t\tkubectl delete -f .\/pod.json\n\n\t\t# Delete a pod based on the type and name in the JSON passed into stdin.\n\t\tcat pod.json | kubectl delete -f -\n\n\t\t# Delete pods and services with same names \"baz\" and \"foo\"\n\t\tkubectl delete pod,service baz foo\n\n\t\t# Delete pods and services with label name=myLabel.\n\t\tkubectl delete pods,services -l name=myLabel\n\n\t\t# Delete a pod with minimal delay\n\t\tkubectl delete pod foo --now\n\n\t\t# Force delete a pod on a dead node\n\t\tkubectl delete pod foo --grace-period=0 --force\n\n\t\t# Delete a pod with UID 1234-56-7890-234234-456456.\n\t\tkubectl delete pod 1234-56-7890-234234-456456\n\n\t\t# Delete all pods\n\t\tkubectl delete pods --all`)\n)\n\nfunc NewCmdDelete(f cmdutil.Factory, out, errOut io.Writer) *cobra.Command {\n\toptions := &resource.FilenameOptions{}\n\n\t\/\/ retrieve a list of handled resources from printer as valid args\n\tvalidArgs, argAliases := []string{}, []string{}\n\tp, err := f.Printer(nil, kubectl.PrintOptions{\n\t\tColumnLabels: []string{},\n\t})\n\tcmdutil.CheckErr(err)\n\tif p != nil {\n\t\tvalidArgs = p.HandledResources()\n\t\targAliases = kubectl.ResourceAliases(validArgs)\n\t}\n\n\tcmd := &cobra.Command{\n\t\tUse:     \"delete ([-f FILENAME] | TYPE [(NAME | -l label | --all)])\",\n\t\tShort:   \"Delete resources by filenames, stdin, resources and names, or by resources and label selector\",\n\t\tLong:    delete_long,\n\t\tExample: delete_example,\n\t\tRun: func(cmd *cobra.Command, args []string) {\n\t\t\tcmdutil.CheckErr(cmdutil.ValidateOutputArgs(cmd))\n\t\t\terr := RunDelete(f, out, errOut, cmd, args, options)\n\t\t\tcmdutil.CheckErr(err)\n\t\t},\n\t\tSuggestFor: []string{\"rm\"},\n\t\tValidArgs:  validArgs,\n\t\tArgAliases: argAliases,\n\t}\n\tusage := \"containing the resource to delete.\"\n\tcmdutil.AddFilenameOptionFlags(cmd, options, usage)\n\tcmd.Flags().StringP(\"selector\", \"l\", \"\", \"Selector (label query) to filter on.\")\n\tcmd.Flags().Bool(\"all\", false, \"[-all] to select all the specified resources.\")\n\tcmd.Flags().Bool(\"ignore-not-found\", false, \"Treat \\\"resource not found\\\" as a successful delete.

One channel\n\/\/ handles writing data out by making sequential POST requests to the server\n\/\/ which encapsulate the outbound data in their request bodies, while the other\n\/\/ channel handles reading data by making GET requests and grabbing the data\n\/\/ encapsulated in the response bodies.\n\/\/\n\/\/ Write Channel:\n\/\/\n\/\/   1. Accept writes, piping these to the proxy as the body of an http POST\n\/\/   2. Continue to pipe the writes until the pause between consecutive writes\n\/\/      exceeds the IdleInterval, at which point we finish the request body. We\n\/\/      do this because it is assumed that intervening proxies (e.g. CloudFlare\n\/\/      CDN) do not allow streaming requests, so it is necessary to finish the\n\/\/      request for data to get flushed to the destination server.\n\/\/   3.

We\n\/\/      do this because it is assumed that intervening proxies (e.g. CloudFlare\n\/\/      CDN) do not allow streaming requests, so it is necessary to finish the\n\/\/      request for data to get flushed to the destination server.\n\/\/   3.

{"text":"<commit_before>\/*Package assert provides assertions for comparing expected values to actual\nvalues. When an assertion fails a helpful error message is printed.\n\nAssert and Check\n\nAssert() and Check() both accept a Comparison, and fail the test when the\ncomparison fails.
