The data is expected to be\n\/\/ of a valid influxDB format. As the data format changed between influxDB\n\/\/ versions it is advisable to use a formatter for the specific influxDB version\n\/\/ you want to write to.

Defaults to 100.\n\/\/\n\/\/ BatchMaxCount defines the maximum number of messages that can be buffered\n\/\/ before a flush is mandatory. If the buffer is full and a flush is still\n\/\/ underway or cannot be triggered out of other reasons, the producer will\n\/\/ block. By default this is set to 8192.\n\/\/\n\/\/ BatchFlushCount defines the number of messages to be buffered before they are\n\/\/ written to InfluxDB. This setting is clamped to BatchMaxCount.\n\/\/ By default this is set to BatchMaxCount \/ 2.\n\/\/\n\/\/ BatchTimeoutSec defines the maximum number of seconds to wait after the last\n\/\/ message arrived before a batch is flushed automatically.

The layout defines the format by showing how\nthe reference time, defined to be\n\nMon Jan 2 15:04:05 -0700 MST 2006\nwould be interpreted if it were the value; it serves as an example of the input format. The same interpretation will\nthen be made to the input string.\n\nPredefined layouts ANSIC, UnixDate, RFC3339 and others describe standard and convenient representations of the\nreference time. For more information about the formats and the definition of the reference time, see the documentation\nfor ANSIC and the other constants defined by this package. Also, the executable example for time.Format demonstrates\nthe working of the layout string in detail and is a good reference.\n\nElements omitted from the value are assumed to be zero or, when zero is impossible, one, so parsing \"3:04pm\" returns\nthe time corresponding to Jan 1, year 0, 15:04:00 UTC (note that because the year is 0, this time is before the zero\nTime). Years must be in the range 0000..9999. The day of the week is checked for syntax but it is otherwise ignored.\n\nIn the absence of a time zone indicator, Parse returns a time in UTC.\n\nWhen parsing a time with a zone offset like -0700, if the offset corresponds to a time zone used by the current\nlocation (Local), then Parse uses that location and zone in the returned time. Otherwise it records the time as being\nin a fabricated location with time fixed at the given zone offset.\n\nNo checking is done that the day of the month is within the month's valid dates; any one- or two-digit value is\naccepted. For example February 31 and even February 99 are valid dates, specifying dates in March and May. This\nbehavior is consistent with time.Date.\n\nWhen parsing a time with a zone abbreviation like MST, if the zone abbreviation has a defined offset in the current\nlocation, then that offset is used. The zone abbreviation \"UTC\" is recognized as UTC regardless of location. If the\nzone abbreviation is unknown, Parse records the time as being in a fabricated location with the given zone abbreviation\nand a zero offset. This choice means that such a time can be parsed and reformatted with the same layout losslessly,\nbut the exact instant used in the representation will differ by the actual zone offset. To avoid such problems, prefer\ntime layouts that use a numeric zone offset, or use ParseInLocation.\n\nExample\nfunc ParseInLocation\nfunc ParseInLocation(layout, value string, loc *Location) (Time, error)\nParseInLocation is like Parse but differs in two important ways. First, in the absence of time zone information, Parse\ninterprets a time as UTC; ParseInLocation interprets the time as in the given location. Second, when given a zone\noffset or abbreviation, Parse tries to match it against the Local location; ParseInLocation uses the given location.\n\nfunc (Time) Before\n\nfunc (t Time) Before(u Time) bool\nBefore reports whether the time instant t is before u.\n\nfunc (Time) Clock\nfunc (t Time) Clock() (hour, min, sec int)\nClock returns the hour, minute, and second within the day specified by t.\n\nfunc (Time) Date\nfunc (t Time) Date() (year int, month Month, day int)\nDate returns the year, month, and day in which t occurs.\n\nfunc (Time) Day\nfunc (t Time) Day() int\nDay returns the day of the month specified by t.\n\nfunc (Time) Equal\nfunc (t Time) Equal(u Time) bool\nEqual reports whether t and u represent the same time instant. Two times can be equal even if they are in different\nlocations. For example, 6:00 +0200 CEST and 4:00 UTC are Equal. Do not use == with Time values.\n\nfunc (Time) Format\nfunc (t Time) Format(layout string) string\n\ntype Duration int64\nA Duration represents the elapsed time between two instants as an int64 nanosecond count. The representation limits the\nlargest representable duration to approximately 290 years.\n\nconst (\n    Nanosecond  Duration = 1\n    Microsecond          = 1000 * Nanosecond\n    Millisecond          = 1000 * Microsecond\n    Second               = 1000 * Millisecond\n    Minute               = 60 * Second\n    Hour                 = 60 * Minute\n)\n\nfunc AfterFunc\nfunc AfterFunc(d Duration, f func()) *Timer\nAfterFunc waits for the duration to elapse and then calls f in its own goroutine.

Also, the executable example for time.Format demonstrates\nthe working of the layout string in detail and is a good reference.\n\nElements omitted from the value are assumed to be zero or, when zero is impossible, one, so parsing \"3:04pm\" returns\nthe time corresponding to Jan 1, year 0, 15:04:00 UTC (note that because the year is 0, this time is before the zero\nTime). Years must be in the range 0000..9999. The day of the week is checked for syntax but it is otherwise ignored.\n\nIn the absence of a time zone indicator, Parse returns a time in UTC.\n\nWhen parsing a time with a zone offset like -0700, if the offset corresponds to a time zone used by the current\nlocation (Local), then Parse uses that location and zone in the returned time. Otherwise it records the time as being\nin a fabricated location with time fixed at the given zone offset.\n\nNo checking is done that the day of the month is within the month's valid dates; any one- or two-digit value is\naccepted. For example February 31 and even February 99 are valid dates, specifying dates in March and May. This\nbehavior is consistent with time.Date.\n\nWhen parsing a time with a zone abbreviation like MST, if the zone abbreviation has a defined offset in the current\nlocation, then that offset is used. The zone abbreviation \"UTC\" is recognized as UTC regardless of location. If the\nzone abbreviation is unknown, Parse records the time as being in a fabricated location with the given zone abbreviation\nand a zero offset. This choice means that such a time can be parsed and reformatted with the same layout losslessly,\nbut the exact instant used in the representation will differ by the actual zone offset. To avoid such problems, prefer\ntime layouts that use a numeric zone offset, or use ParseInLocation.\n\nExample\nfunc ParseInLocation\nfunc ParseInLocation(layout, value string, loc *Location) (Time, error)\nParseInLocation is like Parse but differs in two important ways. First, in the absence of time zone information, Parse\ninterprets a time as UTC; ParseInLocation interprets the time as in the given location. Second, when given a zone\noffset or abbreviation, Parse tries to match it against the Local location; ParseInLocation uses the given location.\n\nfunc (Time) Before\n\nfunc (t Time) Before(u Time) bool\nBefore reports whether the time instant t is before u.\n\nfunc (Time) Clock\nfunc (t Time) Clock() (hour, min, sec int)\nClock returns the hour, minute, and second within the day specified by t.\n\nfunc (Time) Date\nfunc (t Time) Date() (year int, month Month, day int)\nDate returns the year, month, and day in which t occurs.\n\nfunc (Time) Day\nfunc (t Time) Day() int\nDay returns the day of the month specified by t.\n\nfunc (Time) Equal\nfunc (t Time) Equal(u Time) bool\nEqual reports whether t and u represent the same time instant. Two times can be equal even if they are in different\nlocations. For example, 6:00 +0200 CEST and 4:00 UTC are Equal. Do not use == with Time values.\n\nfunc (Time) Format\nfunc (t Time) Format(layout string) string\n\ntype Duration int64\nA Duration represents the elapsed time between two instants as an int64 nanosecond count. The representation limits the\nlargest representable duration to approximately 290 years.\n\nconst (\n    Nanosecond  Duration = 1\n    Microsecond          = 1000 * Nanosecond\n    Millisecond          = 1000 * Microsecond\n    Second               = 1000 * Millisecond\n    Minute               = 60 * Second\n    Hour                 = 60 * Minute\n)\n\nfunc AfterFunc\nfunc AfterFunc(d Duration, f func()) *Timer\nAfterFunc waits for the duration to elapse and then calls f in its own goroutine. It returns a Timer that can be used\nto cancel the call using its Stop method.\n*\/\n<|endoftext|>"}

The one problem is that Apple is doing in-place conversion\n\t\/\/ of HFS volumes as they're rolling out APFS, and it's not clear if they're\n\t\/\/ converting to NFC as part of that (I seriously doubt it).

Unfortunately there's not really a good heuristic for\n\t\/\/ determining which decomposed filenames on an APFS volume are due to HFS'\n\t\/\/ behavior. We could assume that all decomposed filenames on APFS volume at\n\t\/\/ like that for this reason, but (a) that's a pretty wild assumption,\n\t\/\/ especially as time goes on, and (b) as HFS dies off and more people\n\t\/\/ switch to APFS (likely though new volume creation), the cross-section of\n\t\/\/ cases where some HFS-induced decomposition is still haunting cross-\n\t\/\/ platform synchronization is going to become vanishingly small. People can\n\t\/\/ also just fix the problem by fixing the file name normalization once and\n\t\/\/ relying on APFS to preserve it.\n\t\/\/\n\t\/\/ For a complete accounting of APFS' behavior, see the following article:\n\t\/\/ \thttps:\/\/developer.apple.com\/library\/content\/documentation\/FileManagement\/Conceptual\/APFS_Guide\/FAQ\/FAQ.html\n\t\/\/ Search for \"How does Apple File System handle filenames?\" The behavior\n\t\/\/ was a little inconsistent and crazy during the initial deployment on iOS\n\t\/\/ 10.3, but it's pretty much settled down now, and was always sane on\n\t\/\/ macOS, where its deployment occurred later.

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 is because by default, if you provide no username or\n\/\/ password, the NewConnection function will inspect environment variables\n\/\/ PULSE_USERNAME and PULSE_PASSWORD, and an empty url will trigger the library\n\/\/ to use the current production url. Another example call could be:\n\/\/\n\/\/  conn := pulse.NewConnection(\"guest\", \"guest\", \"amqp:\/\/localhost:5672\/\")\n\/\/\n\/\/ Typically we would set the username and password credentials via environment\n\/\/ variables to avoid hardcoding them in the go code.  For more details about\n\/\/ managing the username, password and amqp url, see the documentation for the\n\/\/ NewConnection function.\n\/\/\n\/\/ A call to NewConnection does not actually create a connection to the pulse\n\/\/ server, it simply prepares the data that will be needed when we finally make\n\/\/ the connection.  Users and passwords can be created by going to the Pulse\n\/\/ Guardian (https:\/\/pulse.mozilla.org) and registering an account.\n\/\/\n\/\/ You will see in the code above, that after creating a connection, there is\n\/\/ only one more method we call - Consume - which we use for processing\n\/\/ messages. This is the heart of the pulse library, and where all of the\n\/\/ action happens.\n\/\/\n\/\/ In pulse, all messages are delivered to \"topic exchanges\" and the way to\n\/\/ receive these messages is to request the ones you are interested in are\n\/\/ copied onto a queue you can read from, and then to read them from the queue.\n\/\/ This is called binding. To bind messages from an exchange to a queue, you\n\/\/ specify the name of the exchange you want to receive messages from, and a\n\/\/ matching criteria to define the ones you want. The matching process is\n\/\/ handled by routing keys, which will now be explained.\n\/\/\n\/\/ Each message that arrives on an exchange has a \"routing key\" signature.  The\n\/\/ routing key comprises of several fields. For an example, see:\n\/\/ http:\/\/docs.taskcluster.net\/queue\/exchanges\/#taskDefined.  The fields are\n\/\/ delimited by dots, and therefore the routing key of a message is represented\n\/\/ as a '.' delimited string.  In order to select the messages on an exchange\n\/\/ that you wish to receive, you specify a matching routing key.  For each\n\/\/ field of the routing key, you can either match against a specific value, or\n\/\/ match all entries with the '*' wildcard.  Above, we specified the following\n\/\/ routing key and exchange:\n\/\/\n\/\/  \t\tpulse.Bind( \/\/ routing key and exchange to get messages from\n\/\/  \t\t\"*.*.*.*.*.*.gaia.#\",\n\/\/  \t\t\"exchange\/taskcluster-queue\/v1\/task-defined\"),\n\/\/\n\/\/ This would match all messages on the exchange\n\/\/ \"exchange\/taskcluster-queue\/v1\/task-defined\" which have a workerType of\n\/\/ \"gaia\" (see the taskDefined link above).  Notice also the '#' at the end of\n\/\/ the string. This means \"match all remaining fields\" and can be used to match\n\/\/ whatever comes after.\n\/\/\n\/\/ To see the list of available exchanges on pulse, visit\n\/\/ https:\/\/wiki.mozilla.org\/Auto-tools\/Projects\/Pulse\/Exchanges.\n\/\/\n\/\/ After deciding which exchanges you are interested in, you need a queue to\n\/\/ have them copied onto. This is also handled by the Consume method, with the\n\/\/ first argument being the name of the queue to use.  You will notice above\n\/\/ there are two types of queues we create: named queues, and unnamed queues:\n\/\/\n\/\/  \tconn.Consume(\n\/\/  \t\t\"taskprocessing\", \/\/ queue name\n\/\/\n\/\/  \tconn.Consume( \/\/ a second workflow to manage concurrently\n\/\/  \t\t\"\", \/\/ empty name implies anonymous queue\n\/\/\n\/\/ To understand the difference, first we need to explain the different\n\/\/ scenarios in which you might want to use them.\n\/\/\n\/\/ Scenario 1) You have one client reading from the queue, and when you\n\/\/ disconnect, you don't want your queue to receive any more messages\n\/\/\n\/\/ Scenario 2) you have multiple clients that want to feed from the same queue\n\/\/ (e.g.  when multiple workers can perform the same task, and whichever one\n\/\/ pops the message off the queue first should process it)\n\/\/\n\/\/ Scenario 3) you only have a single client reading from the queue, but if you\n\/\/ go offline (crash, network interrupts etc) then you want pulse to keep\n\/\/ updating your queue so your missed messages are there when you get back.\n\/\/\n\/\/ In scenario 1 above, your client only uses the queue for the scope of the\n\/\/ connection, and as soon as it disconnects, does not require the queue any\n\/\/ further. In this case, an unnamed queue can be created, by passing \"\" as the\n\/\/ queue name. When the connection closes, the AMQP server will automatically\n\/\/ delete the queue.\n\/\/\n\/\/ In scenarios 2 it is useful to have a friendly name for the queue that can\n\/\/ be shared by all the clients using it.  The queue also should not be deleted\n\/\/ when one client disconnects, it needs to live indefinitely. By providing a\n\/\/ name for the queue, this signifies to the pulse library, that the queue\n\/\/ should persist after a disconnect, and pulse should continue to populate the\n\/\/ queue, even if no pulse clients are connected to consume the messages.\n\/\/ Please note eventually the Pulse Guardian will delete your queue if you\n\/\/ leave it collecting messages without consuming them.\n\/\/\n\/\/ Scenario 3 is essentially the same as scenario 2 but with one consumer only.\n\/\/ Again, a named queue is required.\n\/\/\n\/\/ So, we're nearly done now. We now have a means to consume messages, by\n\/\/ calling the Consume method, and specifying a queue name, some bindings of\n\/\/ exchanges and routing keys, but how to actually process messages arriving on\n\/\/ the queue?\n\/\/\n\/\/ You will notice the Consume method takes a callback function. This can be an\n\/\/ inline function, or point to any available function in your go code. You\n\/\/ simply need to have a function that accepts an amqp.Delivery input, and pass\n\/\/ it into the Consume method. Above, we did it like this:\n\/\/\n\/\/  \t\tfunc(message interface{}, delivery amqp.Delivery) { \/\/ callback function to pass messages to\n\/\/  \t\t\tfmt.Println(\"Received from exchange \" + delivery.Exchange + \":\")\n\/\/  \t\t\tfmt.Println(string(delivery.Body))\n\/\/  \t\t\tfmt.Println(\"\")\n\/\/  \t\t\tdelivery.Ack(false) \/\/ acknowledge message *after* processing\n\/\/  \t\t},\n\/\/\n\/\/ The two parameters of the callback function we have created are the message\n\/\/ object, and the delivery object. The message object is the pulse message,\n\/\/ but unmarshaled into an interface{}. Since the pulse messages are all json\n\/\/ messages, the pulse library unmarshals it and give you back a go object with\n\/\/ its contents. Please note if you require that the json is unmarshaled into\n\/\/ something more specific than interface{}, such as a custom class, this is\n\/\/ possible, and will be explained in the next paragraph.  The other parameter,\n\/\/ the delivery object, is an underlying amqp library type, which gives you\n\/\/ access to some meta data for the message.  Please see\n\/\/ http:\/\/godoc.org\/github.com\/streadway\/amqp#Delivery for more information.\n\/\/ Among other things, it provides you with delivery.Body, which is the raw\n\/\/ json of the message. You can therefore choose if you want to process the raw\n\/\/ json or the unmarshaled json in your callback method.\n\/\/\n\/\/ You recall above that to describe the binding from an exchange to a queue\n\/\/ with a given routing key, we specified pulse.Bind(routingKey, exchange) as a\n\/\/ parameter of the Consume method. pulse.Bind(...) returns an object of type ,\n\/\/ where http:\/\/godoc.org\/github.com\/petemoore\/pulse-go\/pulse#Binding is an\n\/\/ interface. If you wish to unmarshal your json into something other than an\n\/\/ interface{}, take a look at the Binding interface documentation. Instead of\n\/\/ calling pulse.Bind(...) you can provide your own Binding interface\n\/\/ implementation which can enable custom handling of exchange names, routing\n\/\/ keys, and unmarshaling of objects. The taskcluster go client relies heavily\n\/\/ on this, for example. See\n\/\/ https:\/\/github.com\/petemoore\/taskcluster-client-go\/tree\/master\/tctasksniffer\/sniffer.go\n\/\/ for inspiration.\n\/\/\n\/\/ In this example above, we simply output the information we receive, and then\n\/\/ acknowledge receipt of the message. But why do we need to do this? To explain,\n\/\/ take a look at the remaining parameters to Consume that we pass in. There\n\/\/ are two more we have not discussed yet: they are the prefetch size (how many\n\/\/ messages to fetch at once), and a bool to say whether to auto-acknowledge\n\/\/ messages or not.\n\/\/\n\/\/  \t\t1,     \/\/ prefetch 1 message at a time\n\/\/  \t\tfalse, \/\/ don't auto-acknowledge messages\n\/\/\n\/\/ When you acknowledge a message, it gets popped off the queue. If you don't\n\/\/ auto-acknowledge, and also don't manually acknowledge, your queue is going\n\/\/ to grow until it gets deleted by Pulse Guardian, so better to acknowledge\n\/\/ those messages!  Auto-acknowledge happens when you receive the message; if\n\/\/ you crash after receiving it but before processing it, you may have a\n\/\/ problem. If it is important not to lose messages in such a scenario, you can\n\/\/ acknowledge manually *after* processing the message. See above:\n\/\/\n\/\/  \t\t\tdelivery.Ack(false) \/\/ acknowledge message *after* processing\n\/\/\n\/\/ This is \"more work\" for you to do, but guarantees that you don't lose\n\/\/ messages. To handle situation of crashing after processing, but before\n\/\/ acknowledging, having an idempotent message processing function (the\n\/\/ callback) should help avoid the problem of processing a message twice.\n\/\/\n\/\/ Please note the Consume method will take care of connecting to the pulse\n\/\/ server (if no connection has yet been established), creating an AMQP\n\/\/ channel, creating or connecting to an existing queue, binding it to all the\n\/\/ exchanges and routing keys that you specify, and spawning a dedicated go\n\/\/ routine to process the messages from this queue and feed them back to the\n\/\/ callback method you provide.\n\/\/\n\/\/ The client is implemented in such a way that a new AMQP channel is created\n\/\/ for each queue that you consume, and that a separate go routine handles\n\/\/ calling the callback function you specify. This means you can take advantage\n\/\/ of go's built in concurrency support, and call the Consume method as many\n\/\/ times as you wish.\n\/\/\n\/\/ The aim of this library is to shield users from this lower-level resource\n\/\/ management, and provide a simple interface in order to quickly and easily\n\/\/ develop components that can interact with pulse.\npackage pulse\n<commit_msg>text corrections<commit_after>\/\/ Package pulse provides operations for consuming mozilla pulse messages (see\n\/\/ https:\/\/pulse.mozilla.org\/).\n\/\/\n\/\/ For users that are interested in publishing messages, or having lower level\n\/\/ control of the amqp interactions with pulse, take a look at\n\/\/ http:\/\/godoc.org\/github.com\/streadway\/amqp.

This is the heart of the pulse library, and where all of the\n\/\/ action happens.\n\/\/\n\/\/ In pulse, all messages are delivered to \"topic exchanges\" and the way to\n\/\/ receive these messages is to request the ones you are interested in are\n\/\/ copied onto a queue you can read from, and then to read them from the queue.\n\/\/ This is called binding. To bind messages from an exchange to a queue, you\n\/\/ specify the name of the exchange you want to receive messages from, and a\n\/\/ matching criteria to define the ones you want. The matching process is\n\/\/ handled by routing keys, which will now be explained.\n\/\/\n\/\/ Each message that arrives on an exchange has a \"routing key\" signature.  The\n\/\/ routing key comprises of several fields. For an example, see:\n\/\/ http:\/\/docs.taskcluster.net\/queue\/exchanges\/#taskDefined.  The fields are\n\/\/ delimited by dots, and therefore the routing key of a message is represented\n\/\/ as a '.' delimited string.  In order to select the messages on an exchange\n\/\/ that you wish to receive, you specify a matching routing key.  For each\n\/\/ field of the routing key, you can either match against a specific value, or\n\/\/ match all entries with the '*' wildcard.  Above, we specified the following\n\/\/ routing key and exchange:\n\/\/\n\/\/  \t\tpulse.Bind( \/\/ routing key and exchange to get messages from\n\/\/  \t\t\"*.*.*.*.*.*.gaia.#\",\n\/\/  \t\t\"exchange\/taskcluster-queue\/v1\/task-defined\"),\n\/\/\n\/\/ This would match all messages on the exchange\n\/\/ \"exchange\/taskcluster-queue\/v1\/task-defined\" which have a workerType of\n\/\/ \"gaia\" (see the taskDefined link above).  Notice also the '#' at the end of\n\/\/ the string. This means \"match all remaining fields\" and can be used to match\n\/\/ whatever comes after.\n\/\/\n\/\/ To see the list of available exchanges on pulse, visit\n\/\/ https:\/\/wiki.mozilla.org\/Auto-tools\/Projects\/Pulse\/Exchanges.\n\/\/\n\/\/ After deciding which exchanges you are interested in, you need a queue to\n\/\/ have them copied onto. This is also handled by the Consume method, with the\n\/\/ first argument being the name of the queue to use.  You will notice above\n\/\/ there are two types of queues we create: named queues, and unnamed queues:\n\/\/\n\/\/  \tconn.Consume(\n\/\/  \t\t\"taskprocessing\", \/\/ queue name\n\/\/\n\/\/  \tconn.Consume( \/\/ a second workflow to manage concurrently\n\/\/  \t\t\"\", \/\/ empty name implies anonymous queue\n\/\/\n\/\/ To understand the difference, first we need to explain the different\n\/\/ scenarios in which you might want to use them.\n\/\/\n\/\/ Scenario 1) You have one client reading from the queue, and when you\n\/\/ disconnect, you don't want your queue to receive any more messages\n\/\/\n\/\/ Scenario 2) you have multiple clients that want to feed from the same queue\n\/\/ (e.g.  when multiple workers can perform the same task, and whichever one\n\/\/ pops the message off the queue first should process it)\n\/\/\n\/\/ Scenario 3) you only have a single client reading from the queue, but if you\n\/\/ go offline (crash, network interrupts etc) then you want pulse to keep\n\/\/ updating your queue so your missed messages are there when you get back.\n\/\/\n\/\/ In scenario 1 above, your client only uses the queue for the scope of the\n\/\/ connection, and as soon as it disconnects, does not require the queue any\n\/\/ further. In this case, an unnamed queue can be created, by passing \"\" as the\n\/\/ queue name. When the connection closes, the AMQP server will automatically\n\/\/ delete the queue.\n\/\/\n\/\/ In scenarios 2 it is useful to have a friendly name for the queue that can\n\/\/ be shared by all the clients using it.  The queue also should not be deleted\n\/\/ when one client disconnects, it needs to live indefinitely. By providing a\n\/\/ name for the queue, this signifies to the pulse library, that the queue\n\/\/ should persist after a disconnect, and pulse should continue to populate the\n\/\/ queue, even if no pulse clients are connected to consume the messages.\n\/\/ Please note eventually the Pulse Guardian will delete your queue if you\n\/\/ leave it collecting messages without consuming them.\n\/\/\n\/\/ Scenario 3 is essentially the same as scenario 2 but with one consumer only.\n\/\/ Again, a named queue is required.\n\/\/\n\/\/ So, we're nearly done now. We now have a means to consume messages, by\n\/\/ calling the Consume method, and specifying a queue name, some bindings of\n\/\/ exchanges and routing keys, but how to actually process messages arriving on\n\/\/ the queue?\n\/\/\n\/\/ You will notice the Consume method takes a callback function. This can be an\n\/\/ inline function, or point to any available function in your go code. You\n\/\/ simply need to have a function that accepts an amqp.Delivery input, and pass\n\/\/ it into the Consume method. Above, we did it like this:\n\/\/\n\/\/  \t\tfunc(message interface{}, delivery amqp.Delivery) { \/\/ callback function to pass messages to\n\/\/  \t\t\tfmt.Println(\"Received from exchange \" + delivery.Exchange + \":\")\n\/\/  \t\t\tfmt.Println(string(delivery.Body))\n\/\/  \t\t\tfmt.Println(\"\")\n\/\/  \t\t\tdelivery.Ack(false) \/\/ acknowledge message *after* processing\n\/\/  \t\t},\n\/\/\n\/\/ The two parameters of the callback function we have created are the message\n\/\/ object, and the delivery object. The message object is the pulse message,\n\/\/ but unmarshaled into an interface{}. Since the pulse messages are all json\n\/\/ messages, the pulse library unmarshals it and give you back a go object with\n\/\/ its contents. Please note if you require that the json is unmarshaled into\n\/\/ something more specific than interface{}, such as a custom class, this is\n\/\/ possible, and will be explained in the next paragraph.  The other parameter,\n\/\/ the delivery object, is an underlying amqp library type, which gives you\n\/\/ access to some meta data for the message.  Please see\n\/\/ http:\/\/godoc.org\/github.com\/streadway\/amqp#Delivery for more information.\n\/\/ Among other things, it provides you with delivery.Body, which is the raw\n\/\/ json of the message. You can therefore choose if you want to process the raw\n\/\/ json or the unmarshaled json in your callback method.\n\/\/\n\/\/ You recall above that to describe the binding from an exchange to a queue\n\/\/ with a given routing key, we specified pulse.Bind(routingKey, exchange) as a\n\/\/ parameter of the Consume method. pulse.Bind(routingKey, exchange) returns an\n\/\/ object of type Binding, where Binding is an interface.  If you wish to\n\/\/ unmarshal your json into something other than an interface{}, take a look at\n\/\/ the Binding interface documentation\n\/\/ (http:\/\/godoc.org\/github.com\/petemoore\/pulse-go\/pulse#Binding). Instead of\n\/\/ calling pulse.Bind(routingKey, exchange) you can provide your own Binding\n\/\/ interface implementation which can enable custom handling of exchange names,\n\/\/ routing keys, and unmarshaling of objects. The taskcluster go client relies\n\/\/ heavily on this, for example. See\n\/\/ https:\/\/github.com\/petemoore\/taskcluster-client-go\/tree\/master\/tctasksniffer\/sniffer.go\n\/\/ for inspiration.\n\/\/\n\/\/ In this example above, we simply output the information we receive, and then\n\/\/ acknowledge receipt of the message. But why do we need to do this? To explain,\n\/\/ take a look at the remaining parameters to Consume that we pass in. There\n\/\/ are two more we have not discussed yet: they are the prefetch size (how many\n\/\/ messages to fetch at once), and a bool to say whether to auto-acknowledge\n\/\/ messages or not.\n\/\/\n\/\/  \t\t1,     \/\/ prefetch 1 message at a time\n\/\/  \t\tfalse, \/\/ don't auto-acknowledge messages\n\/\/\n\/\/ When you acknowledge a message, it gets popped off the queue. If you don't\n\/\/ auto-acknowledge, and also don't manually acknowledge, your queue is going\n\/\/ to grow until it gets deleted by Pulse Guardian, so better to acknowledge\n\/\/ those messages!  Auto-acknowledge happens when you receive the message; if\n\/\/ you crash after receiving it but before processing it, you may have a\n\/\/ problem. If it is important not to lose messages in such a scenario, you can\n\/\/ acknowledge manually *after* processing the message. See above:\n\/\/\n\/\/  \t\t\tdelivery.Ack(false) \/\/ acknowledge message *after* processing\n\/\/\n\/\/ This is \"more work\" for you to do, but guarantees that you don't lose\n\/\/ messages. To handle situation of crashing after processing, but before\n\/\/ acknowledging, having an idempotent message processing function (the\n\/\/ callback) should help avoid the problem of processing a message twice.\n\/\/\n\/\/ Please note the Consume method will take care of connecting to the pulse\n\/\/ server (if no connection has yet been established), creating an AMQP\n\/\/ channel, creating or connecting to an existing queue, binding it to all the\n\/\/ exchanges and routing keys that you specify, and spawning a dedicated go\n\/\/ routine to process the messages from this queue and feed them back to the\n\/\/ callback method you provide.\n\/\/\n\/\/ The client is implemented in such a way that a new AMQP channel is created\n\/\/ for each queue that you consume, and that a separate go routine handles\n\/\/ calling the callback function you specify. This means you can take advantage\n\/\/ of go's built in concurrency support, and call the Consume method as many\n\/\/ times as you wish.\n\/\/\n\/\/ The aim of this library is to shield users from this lower-level resource\n\/\/ management, and provide a simple interface in order to quickly and easily\n\/\/ develop components that can interact with pulse.\npackage pulse\n<|endoftext|>"}

The\ntarget machine must be able to communicate with the API server, and be able to\naccess the environment storage.\n\nExamples:\n   juju add-machine                      (starts a new machine)\n   juju add-machine lxc                  (starts a new machine with an lxc container)\n   juju add-machine lxc:4                (starts a new lxc container on machine 4)\n   juju add-machine --constraints mem=8G (starts a machine with at least 8GB RAM)\n   juju add-machine ssh:user@10.10.0.3   (manually provisions a machine with ssh)\n\nSee Also:\n   juju help constraints\n`\n\n\/\/ AddMachineCommand starts a new machine and registers it in the environment.\ntype AddMachineCommand struct {\n\tenvcmd.EnvCommandBase\n\t\/\/ If specified, use this series, else use the environment default-series\n\tSeries string\n\t\/\/ If specified, these constraints are merged with those already in the environment.\n\tConstraints   constraints.Value\n\tMachineId     string\n\tContainerType instance.ContainerType\n\tSSHHost       string\n}\n\nfunc (c *AddMachineCommand) Info() *cmd.Info {\n\treturn &cmd.Info{\n\t\tName:    \"add-machine\",\n\t\tArgs:    \"[<container>:machine | <container> | ssh:[user@]host]\",\n\t\tPurpose: \"start a new, empty machine and optionally a container, or add a container to a machine\",\n\t\tDoc:     addMachineDoc,\n\t}\n}\n\nfunc (c *AddMachineCommand) SetFlags(f *gnuflag.FlagSet) {\n\tc.EnvCommandBase.SetFlags(f)\n\tf.StringVar(&c.Series, \"series\", \"\", \"the charm series\")\n\tf.Var(constraints.ConstraintsValue{Target: &c.Constraints}, \"constraints\", \"additional machine constraints\")\n}\n\nfunc (c *AddMachineCommand) Init(args []string) error {\n\terr := c.EnvCommandBase.Init()\n\tif err != nil {\n\t\treturn err\n\t}\n\tif c.Constraints.Container != nil {\n\t\treturn fmt.Errorf(\"container constraint %q not allowed when adding a machine\", *c.Constraints.Container)\n\t}\n\tcontainerSpec, err := cmd.ZeroOrOneArgs(args)\n\tif err != nil {\n\t\treturn err\n\t}\n\tif containerSpec == \"\" {\n\t\treturn nil\n\t}\n\tif strings.HasPrefix(containerSpec, sshHostPrefix) {\n\t\tc.SSHHost = containerSpec[len(sshHostPrefix):]\n\t} else {\n\t\t\/\/ container arg can either be 'type:machine' or 'type'\n\t\tif c.ContainerType, err = instance.ParseContainerType(containerSpec); err != nil {\n\t\t\tif names.IsMachine(containerSpec) || !cmd.IsMachineOrNewContainer(containerSpec) {\n\t\t\t\treturn fmt.Errorf(\"malformed container argument %q\", containerSpec)\n\t\t\t}\n\t\t\tsep := strings.Index(containerSpec, \":\")\n\t\t\tc.MachineId = containerSpec[sep+1:]\n\t\t\tc.ContainerType, err = instance.ParseContainerType(containerSpec[:sep])\n\t\t}\n\t}\n\treturn err\n}\n\nfunc (c *AddMachineCommand) Run(ctx *cmd.Context) error {\n\tif c.SSHHost != \"\" {\n\t\targs := manual.ProvisionMachineArgs{\n\t\t\tHost:    c.SSHHost,\n\t\t\tEnvName: c.EnvName,\n\t\t\tStdin:   ctx.Stdin,\n\t\t\tStdout:  ctx.Stdout,\n\t\t\tStderr:  ctx.Stderr,\n\t\t}\n\t\t_, err := manual.ProvisionMachine(args)\n\t\treturn err\n\t}\n\n\tclient, err := juju.NewAPIClientFromName(c.EnvName)\n\tif err != nil {\n\t\treturn err\n\t}\n\tdefer client.Close()\n\n\tmachineParams := params.AddMachineParams{\n\t\tParentId:      c.MachineId,\n\t\tContainerType: c.ContainerType,\n\t\tSeries:        c.Series,\n\t\tConstraints:   c.Constraints,\n\t\tJobs:          []params.MachineJob{params.JobHostUnits},\n\t}\n\tresults, err := client.AddMachines([]params.AddMachineParams{machineParams})\n\tif err != nil {\n\t\treturn err\n\t}\n\t\/\/ Currently, only one machine is added, but in future there may be several added in one call.\n\tmachineInfo := results[0]\n\tif machineInfo.Error != nil {\n\t\treturn machineInfo.Error\n\t}\n\tmachineId := machineInfo.Machine\n\tif c.ContainerType == \"\" {\n\t\tlogger.Infof(\"created machine %v\", machineId)\n\t} else {\n\t\tlogger.Infof(\"created %q container on machine %v\", c.ContainerType, machineId)\n\t}\n\treturn nil\n}\n<|endoftext|>"}

(July 2013)\nA boiling liquid expanding vapor explosion (BLEVE, \/ˈblɛviː\/ blev-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid above its boiling point.[1]\nContents  [hide]\n1 Mechanism\n1.1 Water example\n1.2 BLEVEs without chemical reactions\n2 Fires\n3 Incidents\n4 Safety measures\n5 See also\n6 References\n7 External links\nMechanism[edit]\n\nThis section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (July 2013)\nThere are three characteristics of liquids which are relevant to the discussion of a BLEVE:\nIf a liquid in a sealed container is boiled, the pressure inside the container increases. As the liquid changes to a gas it expands - this expansion in a vented container would cause the gas and liquid to take up more space. In a sealed container the gas and liquid are not able to take up more space and so the pressure rises. Pressurized vessels containing liquids can reach an equilibrium where the liquid stops boiling and the pressure stops rising. This occurs when no more heat is being added to the system (either because it has reached ambient temperature or has had a heat source removed).\nThe boiling temperature of a liquid is dependent on pressure - high pressures will yield high boiling temperatures, and low pressures will yield low boiling temperatures. A common simple experiment is to place a cup of water in a vacuum chamber, and then reduce the pressure in the chamber until the water boils. By reducing the pressure the water will boil even at room temperature. This works both ways - if the pressure is increased beyond normal atmospheric pressures, the boiling of hot water could be suppressed far beyond normal temperatures. The cooling system of a modern internal combustion engine is a real-world example.\nWhen a liquid boils it turns into a gas. The resulting gas takes up far more space than the liquid did.\nTypically, a BLEVE starts with a container of liquid which is held above its normal, atmospheric-pressure boiling temperature. Many substances normally stored as liquids, such as CO2, propane, and other similar industrial gases have boiling temperatures, at atmospheric pressure, far below room temperature. In the case of water, a BLEVE could occur if a pressurized chamber of water is heated far beyond the standard 100 °C (212 °F). That container, because the boiling water pressurizes it, is capable of holding liquid water at very high temperatures.\nIf the pressurized vessel, containing liquid at high temperature (which may be room temperature, depending on the substance) ruptures, the pressure which prevents the liquid from boiling is lost. If the rupture is catastrophic, where the vessel is immediately incapable of holding any pressure at all, then there suddenly exists a large mass of liquid which is at very high temperature and very low pressure. This causes the entire volume of liquid to instantaneously boil, which in turn causes an extremely rapid expansion. Depending on temperatures, pressures and the substance involved, that expansion may be so rapid that it can be classified as an explosion, fully capable of inflicting severe damage on its surroundings.\nWater example[edit]\nImagine, for example, a tank of pressurized liquid water held at 204.4 °C (400 °F). This tank would normally be pressurized to 1.7 MPa (250 psi) above atmospheric (\"gauge\") pressure. If the tank containing the water were to rupture, there would for a slight moment exist a volume of liquid water which would be\nat atmospheric pressure, and\n204.4 °C (400 °F).\nAt atmospheric pressure the boiling point of water is 100 °C (212 °F) - liquid water at atmospheric pressure cannot exist at temperatures higher than 100 °C (212 °F). At that moment, the water would boil and turn to vapour explosively, and the 204.4 °C (400 °F) liquid water turned to gas would take up a lot more volume than it did as liquid, causing a vapour explosion. Such explosions can happen when the superheated water of a steam engine escapes through a crack in a boiler, causing a boiler explosion.\nBLEVEs without chemical reactions[edit]\nIt is important to note that a BLEVE need not be a chemical explosion—nor does there need to be a fire—however if a flammable substance is subject to a BLEVE it may also be subject to intense heating, either from an external source of heat which may have caused the vessel to rupture in the first place or from an internal source of localized heating such as skin friction. This heating can cause a flammable substance to ignite, adding a secondary explosion caused by the primary BLEVE. While blast effects of any BLEVE can be devastating, a flammable substance such as propane can add significantly to the danger.\nBleve explosion.svg\nWhile the term BLEVE is most often used to describe the results of a container of flammable liquid rupturing due to fire, a BLEVE can occur even with a non-flammable substance such as water,[2] liquid nitrogen,[3] liquid helium or other refrigerants or cryogens, and therefore is not usually considered a type of chemical explosion.\nFires[edit]\nBLEVEs can be caused by an external fire near the storage vessel causing heating of the contents and pressure build-up. While tanks are often designed to withstand great pressure, constant heating can cause the metal to weaken and eventually fail. If the tank is being heated in an area where there is no liquid, it may rupture faster without the liquid to absorb the heat. Gas containers are usually equipped with relief valves that vent off excess pressure, but the tank can still fail if the pressure is not released quickly enough.[1] Relief valves are sized to release pressure fast enough to prevent the pressure from increasing beyond the strength of the vessel, but not so fast as to be the cause of an explosion. An appropriately sized relief valve will allow the liquid inside to boil slowly, maintaining a constant pressure in the vessel until all the liquid has boiled and the vessel empties.\nIf the substance involved is flammable, it is likely that the resulting cloud of the substance will ignite after the BLEVE has occurred, forming a fireball and possibly a fuel-air explosion, also termed a vapor cloud explosion (VCE). If the materials are toxic, a large area will be contaminated.[4]\nIncidents[edit]\nThe term \"BLEVE\" was coined by three researchers at Factory Mutual, in the analysis of an accident there in 1957 involving a chemical reactor vessel.[5]\nIn August 1959 the Kansas City Fire Department suffered its largest ever loss of life in the line of duty, when a 25,000 gallon (95,000 litre) gas tank exploded during a fire on Southwest Boulevard killing five firefighters. This was the first time BLEVE was used to describe a burning fuel tank.[citation needed]\nLater incidents included the Cheapside Street Whisky Bond Fire in Glasgow, Scotland in 1960; Feyzin, France in 1966; Crescent City, Illinois in 1970; Kingman, Arizona in 1973; a liquid nitrogen tank rupture[6] at Air Products and Chemicals and Mobay Chemical Company at New Martinsville, West Virginia on January 31, 1978 [1];Texas City, Texas in 1978; Murdock, Illinois in 1983; San Juan Ixhuatepec, Mexico City in 1984; and Toronto, Ontario in 2008.\nSafety measures[edit]\n[icon]\tThis section requires expansion.

Note that the logic syntax is the\nsame as the template logic syntax in the Go standard library.\nTerse is not an acronym, it is a description of the design of\nthe language.\n\nFeatures\n\n- Significant Whitespace\n\n- Auto-closing tags and functions\n\n- Integrates with other multitemplate languages\n\n- Uses same function calling syntax as stdlib templates\n\nUsing Terse\n\nActive terse as a multitemplate languages by importing the\nterse library like\n\n    import _ \"github.com\/acsellers\/multitemplate\/terse\"\n\nAt that point, Parse will now take a \"terse\" parser for templates\nand ParseFiles\/ParseGlob will detect files with a .terse extension\nas terse formatted files.\n\nAn example terse file:\n\n    #content\n      .title\n        h1= .Title\n        = link_to \"Home\" (url_for \"home\")\n\nThe resulting HTML would look like:\n\n  <div id=\"content\">\n    <div class=\"title\">\n      <h1>Welcome<\/h1>\n      <a href=\"\/home\">Home<\/a>\n    <\/div>\n  <\/div>\n\nSecurity and XSS Protection\n\nTerse uses the built-in protection of html\/template via multitemplate.\n\nSimple HTML\n\nMost of HTML documents is static text. Terse makes writing this static\ntext as simple as possible. There are three ways to write HTML tags, the\nautomatic way, the manual way, and the verbatim way. The automatic way\nwill detect tags by name, and will do a case sensitive search on the\nelements listed in the ValidElements map. The manual way will detect\nelements by a percentage sign before the element name, which is the same\nbehavior as Haml and Bham. Finally, you can just add verbatim HTML code,\nand it wil be passed through to the final output. This is why the character\n'<' has no special meaning in terse.\n\n  \/\/ Source\n  article\n      <h1>My Title<\/h1>\n\n  \/\/ Output\n  <article>\n    <h1>My Title<\/h1>\n  <\/article>\n\nCollapsing Tags\n\nIf you have lines that are simply declaring elements that are nesting,\nyou can collapse the lines using the '>' character. Note that you cannot\nadd attributes or content to the tags. At the moment, you can't use the\nid\/class shorthand here.\n\n  \/\/ Source\n  table > tr > td > %custom_element\n    Gopher Freeman\n\n  \/\/ Output\n  <table><tr><td><custom_element>\n    Gopher Freeman\n  <\/custom_element><\/td><\/tr><\/table>\n\nTemplate Calls\n\nTemplates can be called easily using the >> operator. You may add the name\nof the template without quotes, unless the name would have spaces, in which\ncase you should add quotes to the template name. Then the template call may\nhave a space and a value declaraction (could be ., a $ variable, a function,\na number, string, number, etc) where the value would be passed to the\ntemplate. If you do not provide a value to the template, the dot operator will\nbe assumed to be the value.\n\n  \/\/ Source\n  >>layouts\/navigation.html\n\n  \/\/ Output\n  {{ template \"layouts\/navigation.html\" . }}\n\n  \/\/ Source\n  >>\"beta layouts\/javascript defer.html\" $modules\n\n  \/\/ Output\n  {{ template \"beta layouts\/javascript defer.html\" $modules }}\n\nDefine Statements\n\nDefine statements start with two :'s, then the name for the template. Remember\nthat variables from below the define will not be accessible in the define area.\nAlso remember that a define statement will be pulled out and compiled during\nthe compilation of the parent, and that we will use the name given for the\ntemplate.\n\n  \/\/ Source\n  ::snippets\/title.html\n    h1.title= .\n\n  \/\/ Output\n  {{ define \"snippets.html\" }}\n    <h1 class=\"title\">{{ . }}<\/h1>\n  {{ end }}\n\nClass and Id Shorthand\n\nId's and Class attributes may be specified in shorthand. If you do\nnot specify an html element, terse will assume that you want to use\nthe div element. Multiple class attributes will be combined into the\nclass attribute, while multiple id attributes will take the final id\nattribute. Classes are similar to css declarations, where '.'s precede\nclass attributes and '#'s precede id attributes. You can still provide\nid and class attributes using the standard HTML attributes.\n\n  \/\/ Source\n  #sidebar\n    ul#sidebar_list.vertical_list\n      li.sidebar_element.active Thing\n\n  \/\/ Output\n  <div id=\"sidebar\">\n    <ul id=\"sidebar_list\" class=\"vertical_list\">\n      <li class=\"sidebar_element active\">Thing<\/li>\n    <\/ul>\n  <\/div>\n\nHTML Attributes\n\nThere are two ways to specify attributes, one which allows for multiple\nlines with attributes and another that requires all attributes to be\nspecied on the same line. By specifying the attribute name, then an\nequals sign, then either a string, a $variable, a RenderArg which is\na . followed by words. Finally, if you just specify a helper function.\nNote that if the helper function needs arguments, you should wrap the\nfunction and arguments in parentheses. Boolean HTML attributes, that is\nattributes that have no value, either require parentheses or can have\nthe value 'true' or 'false'.\n\n\n  \/\/ Single Line\n  div id=\"special_thing\" class=$DivIds special thing content\n  \/\/ Output\n  <div id=\"special_thing\" class=\"{{ $DivIds }}\">\n    special thing content\n  <\/div>\n\n\n  \/\/ Multi Line\n  input(\n    name=\"is_active\"\n    type=\"checkbox\"\n    value=\"yes\"\n    checked=.User.Active\n  )\n  \/\/ Output\n  <input type=\"is_active\" type=\"checkbox\" value=\"yes\" checkbox=\"{{.User.Active}}\" \/>\n\n  \/\/ All the ways to specify attributes\n  input(\n    name=$inputName\n    type=\"checkbox\"\n    value=.User.Name\n    checked=(if_print \"checked\" .User.ShowName)\n    class=.Check.User.Class\n  )\n\n  \/\/ Boolean Attribute Option 1\n  .content ng-view=true\n  \/\/ Boolean Attribute Option 2\n  .content(ng-view)\n  \/\/ Output\n  <div class=\"content\" ng-view \/>\n\nDoctype\n\nDoctype lines are prefixed with two exclamation points (!!). There is\nthe default doctype, which is a line with just !!, terse will assume\nyou want to use the HTML5 Doctype (<!DOCTYPE html>). You can modify\nthe terse.Doctypes variable to change to another default by changing\nthe empty string key. Terse includes 8 different Doctypes by default,\nwhich are Transitional (XHTML 1.0 Transitional), Strict (XHTML 1.0\nStrict), Frameset (XHTML 1.0 Frameset), 5 (HTML5), 1.1 (XHTML 1.1),\nBasic (XHTML 1.1 Basic), Mobile (XHTML Mobile 1.2), and RDFa\n(XHTML+RDFa 1.0). These are the same as haml's Doctypes, except\nthat we don't worry about a Format option.\n\n  \/\/ Source\n  !!\n  \/\/ Output\n  <!DOCTYPE html>\n\nComments\n\nBy prefixing lines with a double slash (\/\/), that line and any nested\nlines will be marked as a comment. Comment lines do not show up in the\nrendered template in any way.\n\nExecuting Code\n\nThere are preferred methods for if, range, with, and block functions,\nbut for template functions, there is a generic way to use code in\nyour templates. By adding an = at the start of the line, you can\nmark that line as executable, for multiple lines there is a continuation\nmarker (\/=) which will collapse multiple lines into a single line of code,\nso long as the continuation lines are nested in the first code line. Note\nthat the syntax is the same as text\/template in the standard library,\nand the behavior about inserting code results into the output is same as\nthe text\/template code as well.\n\n  \/\/ Source\n  = print .User\n  \/\/ Output\n  {{ print .User }}\n\n  \/\/ Source\n  = form_tag (url_for \"user.new\") (attrs\n    \/= \"enctype\" \"multipart\/form-data\"\n    \/= \"method\" \"PUT\")\n  \/\/ Output\n  <form action=\"{{ url_for \"user.new\" }}\" enctype=\"multipart\/form-data\" method=\"PUT\">\n\nAuto Closing Functions\n\nWhen lines are nested, terse will look a function another function\nthat has the same name as the function that has the nested name, but\nwith the prefix 'end_'.\n\n  \/\/ Source\n  = fieldset_tag \"Visibility\"\n    = checkbox_tag \"admins\"\n    = checkbox_tag \"users\"\n    = checkbox_tag \"visitors\"\n\n  \/\/ Output\n  {{ fieldset_tag \"Visibility\" }} {{ checkbox_tag \"admins\" }}\n    {{ checkbox_tag \"users\" }}\n    {{ checkbox_tag \"visitors\" }}\n  {{ end_fieldset_tag }}\n\nIf and Else Statements\n\nIf lines begin with a question mark (?), then a statement to be evaluated. The\nmethod of evaluation is the same as text\/template, where if the statement\nevaluates to false, 0, nil, or anything with a length of 0, the statement\nis not executed. Else is an exclamation mark followed by a question mark,\nor \"not the question\".\n\n  \/\/ Source\n  ?.User\n    Welcome\n    = .User.Name\n  !?\n    Please Login\n\n  \/\/ Output\n  {{ if .User }}\n    Welcome\n  {{ else }}\n    Please Login\n  {{ end }}\n\n\nRange Statements\n\nRange statements begin with an ampersand (&). Else statements for ranges\nare an exclamation mark followed by an ampersand (!&). Variables for the\nrange statement are specified using colons after the statement you will\nbe ranging over.\n\n  \/\/ Source\n  &.Users:$user:$index\n    {{ $index }}. {{ $user.Name }}\n  !&\n    No matching users.\n\n  \/\/ Output\n  {{ range $user, $index := .Users }}\n    {{ $index }}. {{ $user.Name }}\n  {{ else }}\n    No matching users.\n  {{ end }}\n\n\nBlock Statements\n\nBlocks are central to multitemplate and terse features\nthem in a first-class manner. The simple block call is [name] where\nname is the name you are using for that block. If you a special\nform of the block statement, just replace the opening '['. For an\nexec block you use a $, while define block uses a ^. The mnemonic\nfor those is that exec is the end of a block, so it is a regex endline\nsymbol ($), while define-block is more a beginning statement, and the\nregex character for the beginning of line is ^. Blocks are automatically\nclosed in terse.\n\n  \/\/ Source\n  [content]\n    h1\n      Welcome\n      = .User.Name\n\n  \/\/ Output\n  {{ block \"content\" }}\n    <h1>Welcome {{.User.Name }}<\/h1>\n  {{ end_block }}\n\n  \/\/ Source\n  ^content]\n    I'm defining this block and not outputting here.\n  \/\/ Output\n  {{ define_block \"content\" }}\n    I'm defining this block and not outputting here.\n  {{ end_block }}\n\n  \/\/ Source\n  $content]\n    We will definitely put some block content here.\n  \/\/ Output\n  {{ exec_block \"content\" }}\n    We will definitely put some block content here.\n  {{ end_block }}\n\nYield Statements\n\nYield statements (for blocks or templates) are written as @name,\nwhere name is the name you are using for that block or template.\n\n  \/\/ Source\n  #content\n    @content\n\n  \/\/ Output\n  <div id=\"content\">\n    {{ yield \"content\" }}\n  <\/div>\n\nExtend Statements\n\nExtend statements (for inheriting from other templates) are written\nusing @@ followed by the template name (without quotation marks).\n\n  \/\/ Source\n  @@layouts\/app.html\n\n  \/\/ Output\n  {{ extend \"layouts\/app.html\" }}\n\nWith Statements\n\nA with statement takes a pipeline and either sets the dot or a variable\nto the value. With statments will only execute if the value is not a\nfalsey value (0, false, nil, empty string, array, slice or map). With\nstatements can have else statements, which are signified by a !>.\n\n  \/\/ Source\n  >.Current.User\n    Welcome\n    = .Name\n    ?time_gt .LastLogin \"3w\"\n      It's been a while\n  !>\n    Please login\n\n  \/\/ Output\n  {{ with .Current.User }}\n    Welcome\n    {{ .Name }}\n    {{ if time_gt .LastLogin \"3w\" }}\n      It's been a while\n    {{ end }}\n  {{ end }}\n\n  \/\/ Source\n  >.Current.Location:$loc\n    = $loc.Name\n\n  \/\/ Output\n  {{ with $loc := .Current.Location }}\n    {{ $loc.Name }}\n  {{ end }}\nInterpolation\n\nIn addition to the function lines, you can also embed functions into\nregular lines, using the Delimeters set on terse (same as the standard\nlibrary delimeters by default).\n\n  \/\/ Source\n  Welcome {{ .User.Name }}.\n\n  \/\/ Output (same)\n  Welcome {{ .User.Name}}.\n\nFilters\n\nFilters are started with a :, then the name of a registered filter.\nFilters can have interpolated code within them, if the filter may\nhave interpolated code, it needs to return true, else if it returns\nfalse, the filtered text will not be checked for code. Note that the\nprocessed text will be inserted into the template and any interpolated\ncode will be processed by html\/template and escaped in a manner\nconsistent with the surrounding text.\n\n  \/\/ Source\n  :js\n    $(document).ready(function{ setup_ajax(); });\n\n  \/\/ Output\n  <script type=\"text\/javascript\">\n    $(document).ready(function{ setup_ajax(); });\n  <\/script>\n\nCurrently there are 3 built-in filters, a plain filter, a javascript filter\n(also aliased as js), and a css filter. The Plain filter will take any nested\nlines and push the straight out to the the text\/template parser. The javascript\nfilter will wrap the text in a script tag, then send it to be processed by the\ntext\/template parser.

Similarly, the css filter will wrap the text in a style\ntag, then send it to the parser.\n\nNotes\n\nRange and With statements use :'s to delineate arguments while template\nstatements use spaces. I'm still thinking about this, and template's will likely\nmove to :'s.\n\nThe format of the documentation and some examples were inspired by\nHaml's REFERENCE file.\n\n*\/\npackage terse\n<|endoftext|>"}

{"text":"<commit_before>\/*\n\n\tauto is a package designed to make it trivial to create MoveTypeConfigs\n\tfor your moves.\n\n\tUse Case\n\n\tCreating MoveTypeConfig is a necessary part of installing moves on your\n\tGameManager, but it's verbose and error-prone. You need to create a lot of\n\textra structs, and then remember to provide the right properties in your\n\tconfig.

There are some rare cases where you do want to\n\trefer to the move by name (and not rely on finicky string-based lookup),\n\tsuch as when you want an Agent to propose a speciifc type of move. In\n\tthose cases use auto.Config to create the move type config, then save the\n\tresulting config's Name to a global variable that you use elsewhere, and\n\tthen pass the created config to bundle.AddMoves (or its cousins).\n\n\tIn general, you should only create a bespoke Move struct in your game if\n\tit is not possible to use one of the off-the-shelf moves from the moves\n\tpackage, combined with configuarion options, to do what you want. In\n\tpractice this means that only if you need to override a method on one of\n\tthe base moves do you need to create a bespoke struct. This typically\n\tallows you to drastically reduce the number of bespoke move structs your\n\tgame defines, saving thousands of lines of code (each bespoke struct also\n\thas hundreds of lines of auto-generated PropertyReader code).\n\n\tIf you do create a bespoke struct, name it like this: \"MoveNameOfMyMove\",\n\tso that moves.Base's default MoveTypeName() will give it a reasonable name\n\tautomatically (in this example, \"Name Of My Move\").\n\n\tIn many cases if you subclass powerful moves like DealCountComponents the\n\tdefault MoveTypeHelpText() value is sufficient (especially if it's a FixUp\n\tmove that won't ever be seen by players). In other cases, WithHelpText()\n\tis often the only config option you will pass to auto.Config.\n\n\tIf your move will be a FixUp move that doesn't sublcass one of the more\n\tadvanced fix up moves (like RoundRobin or DealCountComponents), embed\n\tmoves.FixUp into your struct. That will cause MoveTypeIsFixUp to return\n\tthe right value even without using WithIsFixUp--because WithIsFixUp is\n\teasy to forget given that it's often in a different file. In almost all\n\tcases if you use WithIsFixUp you should simply embed moves.FixUp instead.\n\n\tauto.MustConfig is like auto.Config, but instead of returning a\n\t*MoveTypeConfig and an error, it simply returns a *MoveTypeConfig--and\n\tpanics if it would have returned an error. Since your GameDelegate's\n\tConfigureMoves() is typically called during the boot-up sequence of your\n\tgame, it is safe to use auto.MustConfig exclusively, which saves many\n\tlines of boilerplate error checking.\n\n*\/\npackage auto\n<commit_msg>Update documentation to make it clear that if you give bad validation to moves they will error.

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.

{"text":"<commit_before>\/*\n  REVISION HISTORY\n  ----------------\n  20 Mar 20 -- Made comparisons case insensitive.  And decided to make this cgrepi.go.\n                 And then I figured I could not improve performance by using more packages.\n                 But I can change the side effect of displaying altered case.\n  22 Mar 20 -- Will add timing code that I wrote for anack.\n  27 Mar 21 -- Changed commandLineFiles in platform specific code, and added the -g flag to force globbing.\n  14 Dec 21 -- I'm porting the changed I wrote to multack here.  Also, I noticed that this is mure complex than it\n                 needs to be.  I'm going to take a crack at writing a simpler version myself.\n                 It takes a list of files from the command line (or on windows, a globbing pattern) and iterates\n                 thru all of the files in the list.  Then it exits.  But this is using 2 channels.  I have to understand\n                 this better.  It seems much too complex.  I'm going to simplify it.\n  16 Dec 21 -- Adding a waitgroup, as the sleep at the end is a kludge.  And will only start number of worker go routines to match number of files.\n  19 Dec 21 -- Will add the more selective use of atomic instructions as I learned about from Bill Kennedy and is in cgrepi2.go.  But I will\n                 keep reading the file line by line.  Can now time difference when number of atomic operations is reduced.\n                 Cgrepi2 is still faster, so most of the slowness here is the line by line file reading.\n  30 Sep 22 -- Got idea from ripgrep about smart case, where if input string is all lower case, then the search is  ase insensitive.\n                 But if input string has an upper case character, then the search is case sensitive.\n   1 Oct 22 -- Will not search further in a file if there's a null byte.  I also got this idea from ripgrep.  And I added more info to be displayed if verbose is set.\n   2 Oct 22 -- The extension system is made mostly obsolete by null byte detection.  So the default will be *.  But I discovered when the files slice exceeds 1790 elements,\n                 the go routines all deadlock, so the wait group is not exiting.\n\n               Posted to gonuts using the go playground for the code: 10\/2\/22 @1:35 pm   go playground sharing link: https:\/\/go.dev\/play\/p\/gIVVLsiTqod\/\n                 Moved location of the wait statement, as suggested by Jan Merci.  I guess both a waitgroup and a channel are used for the syncronization.\n                 Nope, then I got a negative WaitGroup number panic.  I moved it back, for now.\n\n               Looks like the error was the order of the defer and if err statements.  The way I first had it, defer was after the if err, so if there was a file error\n                 (like the three access is denied errors I'm seeing from \"My Videos\", \"My Music\", and \"MY Pictures\") then wg.Done() would not be called.\n                 So the wait group count would not go down to zero.  How subtle, and I needed help from someone else to notice that.\n*\/\npackage main\n\nimport (\n\t\"bufio\"\n\t\"flag\"\n\t\"fmt\"\n\t\"log\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"regexp\"\n\t\"runtime\"\n\t\"strings\"\n\t\"sync\"\n\t\"sync\/atomic\"\n\t\"time\"\n)\n\nconst LastAltered = \"2 Oct 2022\"\nconst maxSecondsToTimeout = 300\n\nconst workerPoolMultiplier = 20\nconst null = 0 \/\/ null rune to be used for strings.ContainsRune in GrepFile below.\n\nvar workers = runtime.NumCPU() * workerPoolMultiplier\n\ntype grepType struct {\n\tregex    *regexp.Regexp\n\tfilename string\n\tgoRtnNum int\n}\n\nvar caseSensitiveFlag bool \/\/ default is false.\nvar grepChan chan grepType\nvar totFilesScanned, totMatchesFound int64\nvar t0, tfinal time.Time\nvar wg sync.WaitGroup\n\nfunc main() {\n\truntime.GOMAXPROCS(runtime.NumCPU()) \/\/ Use all the machine's cores\n\tlog.SetFlags(0)\n\n\t\/\/ flag definitions and processing\n\tglobFlag := flag.Bool(\"g\", false, \"force use of globbing, only makes sense on Windows.\") \/\/ Ptr\n\tverboseFlag := flag.Bool(\"v\", false, \"Verbose flag\")\n\tvar timeoutOpt = flag.Int64(\"timeout\", maxSecondsToTimeout, \"seconds (0 means no timeout)\")\n\t\/\/maxFiles := flag.Int64(\"max\", 1000, \"Maximum files to process.

And decided to make this cgrepi.go.\n                 And then I figured I could not improve performance by using more packages.\n                 But I can change the side effect of displaying altered case.\n  22 Mar 20 -- Will add timing code that I wrote for anack.\n  27 Mar 21 -- Changed commandLineFiles in platform specific code, and added the -g flag to force globbing.\n  14 Dec 21 -- I'm porting the changed I wrote to multack here.  Also, I noticed that this is mure complex than it\n                 needs to be.  I'm going to take a crack at writing a simpler version myself.\n                 It takes a list of files from the command line (or on windows, a globbing pattern) and iterates\n                 thru all of the files in the list.  Then it exits.  But this is using 2 channels.  I have to understand\n                 this better.  It seems much too complex.  I'm going to simplify it.\n  16 Dec 21 -- Adding a waitgroup, as the sleep at the end is a kludge.  And will only start number of worker go routines to match number of files.\n  19 Dec 21 -- Will add the more selective use of atomic instructions as I learned about from Bill Kennedy and is in cgrepi2.go.  But I will\n                 keep reading the file line by line.  Can now time difference when number of atomic operations is reduced.\n                 Cgrepi2 is still faster, so most of the slowness here is the line by line file reading.\n  30 Sep 22 -- Got idea from ripgrep about smart case, where if input string is all lower case, then the search is  ase insensitive.\n                 But if input string has an upper case character, then the search is case sensitive.\n   1 Oct 22 -- Will not search further in a file if there's a null byte.  I also got this idea from ripgrep.  And I added more info to be displayed if verbose is set.\n   2 Oct 22 -- The extension system is made mostly obsolete by null byte detection.  So the default will be *.  But I discovered when the files slice exceeds 1790 elements,\n                 the go routines all deadlock, so the wait group is not exiting.\n\n               Posted to gonuts using the go playground for the code: 10\/2\/22 @1:35 pm   go playground sharing link: https:\/\/go.dev\/play\/p\/gIVVLsiTqod\/\n                 Moved location of the wait statement, as suggested by Jan Merci.  I guess both a waitgroup and a channel are used for the syncronization.\n                 Nope, then I got a negative WaitGroup number panic.  I moved it back, for now.\n\n               First reported to me by Matthew Zimmerman.\n               Looks like the error was the order of the defer and if err statements.  The way I first had it, defer was after the if err, so if there was a file error\n                 (like the three access is denied errors I'm seeing from \"My Videos\", \"My Music\", and \"MY Pictures\") then wg.Done() would not be called.\n                 So the wait group count would not go down to zero.  How subtle, and I needed help from someone else to notice that.\n\n               Andrew Harris noticed that the condition for closing the channel could be when all work is sent into it.  I was closing the channel after all work was done.\n                 So I changed that and noticed that it's still possible for the main routine to finish before some of the last grepFile calls.  I still need the WaitGroup.\n*\/\npackage main\n\nimport (\n\t\"bufio\"\n\t\"flag\"\n\t\"fmt\"\n\t\"log\"\n\t\"os\"\n\t\"path\/filepath\"\n\t\"regexp\"\n\t\"runtime\"\n\t\"strings\"\n\t\"sync\"\n\t\"sync\/atomic\"\n\t\"time\"\n)\n\nconst LastAltered = \"2 Oct 2022\"\nconst maxSecondsToTimeout = 300\n\nconst workerPoolMultiplier = 20\nconst null = 0 \/\/ null rune to be used for strings.ContainsRune in GrepFile below.\n\nvar workers = runtime.NumCPU() * workerPoolMultiplier\n\ntype grepType struct {\n\tregex    *regexp.Regexp\n\tfilename string\n\tgoRtnNum int\n}\n\nvar caseSensitiveFlag bool \/\/ default is false.\nvar grepChan chan grepType\nvar totFilesScanned, totMatchesFound int64\nvar t0, tfinal time.Time\n\nvar wg sync.WaitGroup\n\nfunc main() {\n\truntime.GOMAXPROCS(runtime.NumCPU()) \/\/ Use all the machine's cores\n\tlog.SetFlags(0)\n\n\t\/\/ flag definitions and processing\n\tglobFlag := flag.Bool(\"g\", false, \"force use of globbing, only makes sense on Windows.\") \/\/ Ptr\n\tverboseFlag := flag.Bool(\"v\", false, \"Verbose flag\")\n\tvar timeoutOpt = flag.Int64(\"timeout\", maxSecondsToTimeout, \"seconds (0 means no timeout)\")\n\t\/\/maxFiles := flag.Int64(\"max\", 1000, \"Maximum files to process.

{"text":"<commit_before>\/*\nPackage workerpool queues work to a limited number of goroutines.\n\nThe purpose of the worker pool is to limit the concurrency of the task\nperformed by the workers.  This is useful when performing a task that requires\nsufficient resources (CPU, memory, etc.), that running too many tasks at the\nsame time would exhaust resources.\n\nNon-blocking task submission\n\nA task is a function submitted to the worker pool for execution.  Submitting\ntasks to this worker pool will not block, regardless of the number of tasks.\nTasks read from the input task queue are immediately dispatched to an available\nworker.  If no worker is immediately available, or there are already tasks\nwaiting for an available worker, then the task is put on a waiting queue to\nwait for an available worker.  This clears the incoming task from the task\nqueue immediately, whether or not a worker is currently available, and will not\nblock the submission of tasks.\n\nThe intent of the worker pool is to limit the concurrency of task execution,\nnot limit the number of tasks queued to be executed.  Therefore, this unbounded\ninput of tasks is acceptable as the tasks cannot be discarded.  If the number\nof inbound tasks is too many to even queue for pending processing, then the\nsolution is outside the scope of workerpool, and should be solved by\ndistributing load over multiple systems, and\/or storing input for pending\nprocessing in intermediate storage such as a database, file system, distributed\nmessage queue, etc.\n\nDispatcher\n\nThis worker pool uses a single dispatcher goroutine to read tasks from the\ninput task queue and dispatch them to a worker goroutine.  This allows for a\nsmall input channel, and lets the dispatcher queue as many tasks as are\nsubmitted when there are no available workers.  Additionally, the dispatcher\ncan adjust the number of workers as appropriate for the work load, without\nhaving to utilize locked counters and checks incurred on task submission.\n\nWhen no tasks have been submitted for a period of time, a worker is removed by\nthe dispatcher.  This is done until there are no more workers to remove.  The\nminimum number of workers is always zero, because the time to start new workers\nis insignificant.\n\nUsage note\n\nIt is advisable to use different worker pools for tasks that are bound by\ndifferent resources, or that have different resource use patterns.  For\nexample, tasks that use X Mb of memory may need different concurrency limits\nthan tasks that use Y Mb of memory.\n\nWaiting queue vs goroutines\n\nWhen there are no available workers to handle incoming tasks, the tasks are put\non a waiting queue.  In previous versions of workerpool, these tasks were\npassed to goroutines.  Using a queue is faster and has less memory overhead\nthan creating a separate goroutine for each waiting task, allowing a much\nhigher number of waiting tasks.\n\nCredits\n\nThis implementation builds on ideas from the following:\n\nhttp:\/\/marcio.io\/2015\/07\/handling-1-million-requests-per-minute-with-golang\nhttp:\/\/nesv.github.io\/golang\/2014\/02\/25\/worker-queues-in-go.html\n\n*\/\npackage workerpool\n<commit_msg>update doc<commit_after>\/*\nPackage workerpool queues work to a limited number of goroutines.\n\nThe purpose of the worker pool is to limit the concurrency of tasks\nexecuted by the workers.

This clears the incoming task from the input\ntask queue immediately, whether or not a worker is currently available, and\nwill not block the submission of tasks.\n\nThe intent of the worker pool is to limit the concurrency of task execution,\nnot limit the number of tasks queued to be executed.  Therefore, this unbounded\ninput of tasks is acceptable as the tasks cannot be discarded.  If the number\nof inbound tasks is too many to even queue for pending processing, then the\nsolution is outside the scope of workerpool, and should be solved by\ndistributing load over multiple systems, and\/or storing input for pending\nprocessing in intermediate storage such as a database, file system, distributed\nmessage queue, etc.\n\nDispatcher\n\nThis worker pool uses a single dispatcher goroutine to read tasks from the\ninput task queue and dispatch them to a worker goroutine.  This allows for a\nsmall input channel, and lets the dispatcher queue as many tasks as are\nsubmitted when there are no available workers.  Additionally, the dispatcher\ncan adjust the number of workers as appropriate for the work load, without\nhaving to utilize locked counters and checks incurred on task submission.\n\nWhen no tasks have been submitted for a period of time, a worker is removed by\nthe dispatcher.  This is done until there are no more workers to remove.  The\nminimum number of workers is always zero, because the time to start new workers\nis insignificant.\n\nUsage note\n\nIt is advisable to use different worker pools for tasks that are bound by\ndifferent resources, or that have different resource use patterns.  For\nexample, tasks that use X Mb of memory may need different concurrency limits\nthan tasks that use Y Mb of memory.\n\nWaiting queue vs goroutines\n\nWhen there are no available workers to handle incoming tasks, the tasks are put\non a waiting queue.  In previous versions of workerpool, these tasks were\npassed to goroutines.  Using a queue is faster and has less memory overhead\nthan creating a separate goroutine for each waiting task, allowing a much\nhigher number of waiting tasks.\n\nCredits\n\nThis implementation builds on ideas from the following:\n\nhttp:\/\/marcio.io\/2015\/07\/handling-1-million-requests-per-minute-with-golang\nhttp:\/\/nesv.github.io\/golang\/2014\/02\/25\/worker-queues-in-go.html\n\n*\/\npackage workerpool\n<|endoftext|>"}

Everything in\ngithub.com\/wblakecaldwell\/profiler\/profiler-web is bundled up into github.com\/wblakecaldwell\/profiler\/profiler-web.go\nwith the command, assuming your repository is in $GOPATH\/src.\n\nProduction Code Generation (Check this in):\n\n\tgo get github.com\/jteeuwen\/go-bindata\/...\n\tgo install github.com\/jteeuwen\/go-bindata\/go-bindata\n\n\tgo-bindata -prefix \"$GOPATH\/src\/github.com\/wblakecaldwell\/profiler\/profiler-web\/\" -pkg \"profiler\" -nocompress -o \"$GOPATH\/src\/github.com\/wblakecaldwell\/profiler\/profiler-web.go\" \"$GOPATH\/src\/github.com\/wblakecaldwell\/profiler\/profiler-web\"\n\nIf you'd like to make changes to the templates, then use 'go-bindata' in debug mode. Instead of compiling\nthe contents of the template files into profiler-web.go, it generates code to read the content of the template\nfiles as they exist at that moment.

If you're unfamiliar with candidate IDs,\n\/\/ using `\/candidates\/search` will help you locate a particular candidate.\n\/\/\n\/\/ Officially, a candidate is an individual seeking nomination for election to a federal\n\/\/ office. People become candidates when they (or agents working on their behalf)\n\/\/ raise contributions or make expenditures that exceed $5,000.\n\/\/\n\/\/ The candidate endpoints primarily use data from FEC registration\n\/\/ [Form 1](http:\/\/www.fec.gov\/pdf\/forms\/fecfrm1.pdf), for candidate information, and\n\/\/ [Form 2](http:\/\/www.fec.gov\/pdf\/forms\/fecfrm2.pdf), for committee information.\n\/\/\n\/\/\n\/\/ Committee\n\/\/\n\/\/ Committees are entities that spend and raise money in an election. Their characteristics and\n\/\/ relationships with candidates can change over time.\n\/\/\n\/\/ You might want to use filters or search endpoints to find the committee you're looking\n\/\/ for. Then you can use other committee endpoints to explore information about the committee\n\/\/ that interests you.\n\/\/\n\/\/ Financial information is organized by `committee_id`, so finding the committee you're interested in\n\/\/ will lead you to more granular financial information.\n\/\/\n\/\/ The committee endpoints include all FEC filers, even if they aren't registered as a committee.\n\/\/\n\/\/ Officially, committees include the committees and organizations that file with the FEC.\n\/\/ Several different types of organizations file financial reports with the FEC:\n\/\/\n\/\/ * Campaign committees authorized by particular candidates to raise and spend funds in\n\/\/ their campaigns\n\/\/ * Non-party committees (e.g., PACs), some of which may be sponsored by corporations,\n\/\/ unions, trade or membership groups, etc.\n\/\/ * Political party committees at the national, state, and local levels\n\/\/ * Groups and individuals making only independent expenditures\n\/\/ * Corporations, unions, and other organizations making internal communications\n\/\/\n\/\/ The committee endpoints primarily use data from FEC registration Form 1 and Form 2.\n\/\/\n\/\/ Financial\n\/\/\n\/\/ Fetch key information about a committee's Form 3, Form 3X, or Form 3P financial reports.\n\/\/\n\/\/ Most committees are required to summarize their financial activity in each filing; those summaries\n\/\/ are included in these files. Generally, committees file reports on a quarterly or monthly basis, but\n\/\/ some must also submit a report 12 days before primary elections. Therefore, during the primary\n\/\/ season, the period covered by this file may be different for different committees.

If the Function is running\n\tboth locally and remote, the local instance will be invoked.  This behavior\n\tcan be manually overridden using the --target flag.\n\n\tFunctions are invoked with a test data structure consisting of five values:\n\t\tid:            A unique identifier for the request.\n\t\tsource:        A sender name for the request (sender).\n\t\ttype:          A type for the request.\n\t\tdata:          Data (content) for this request.\n\t\tcontent-type:  The MIME type of the value contained in 'data'.\n\n\tThe values of these parameters can be individually altered from their defaults\n\tusing their associated flags. Data can also be provided from a file using the\n\t--file flag.\n\n\tInvocation Target\n\t  The Function instance to invoke can be specified using the --target flag\n\t  which accepts the values \"local\", \"remote\", or <URL>.  By default the\n\t  local Function instance is chosen if running (see {{.Name}} run).\n\t  To explicitly target the remote (deployed) Function:\n\t    {{.Name}} invoke --target=remote\n\t  To target an arbitrary endpoint, provide a URL:\n\t    {{.Name}} invoke --target=https:\/\/myfunction.example.com\n\n\tInvocation Data\n\t  Providing a filename in the --file flag will base64 encode its contents\n\t  as the \"data\" parameter sent to the Function.  The value of --content-type\n\t  should be set to the type from the source file.  For example, the following\n\t  would send a JPEG base64 encoded in the \"data\" POST parameter:\n\t    {{.Name}} invoke --file=example.jpeg --content-type=image\/jpeg\n\n\tMessage Format\n\t  By default Functions are sent messages which match the invocation format\n\t  of the template they were created using; for example \"http\" or \"cloudevent\".\n\t  To override this behavior, use the --format (-f) flag.\n\t    {{.Name}} invoke -f=cloudevent -t=http:\/\/my-sink.my-cluster\n\nEXAMPLES\n\n\to Invoke the default (local or remote) running Function with default values\n\t  $ {{.Name}} invoke\n\n\to Run the Function locally and then invoke it with a test request:\n\t  (run in two terminals or by running the first in the background)\n\t  $ {{.Name}} run\n\t  $ {{.Name}} invoke\n\n\to Deploy and then invoke the remote Function:\n\t  $ {{.Name}} deploy\n\t  $ {{.Name}} invoke\n\n\to Invoke a remote (deployed) Function when it is already running locally:\n\t  (overrides the default behavior of preferring locally running instances)\n\t  $ {{.Name}} invoke --target=remote\n\n\to Specify the data to send to the Function as a flag\n\t  $ {{.Name}} invoke --data=\"Hello World!\"\n\n\to Send a JPEG to the Function\n\t  $ {{.Name}} invoke --file=example.jpeg --content-type=image\/jpeg\n\n\to Invoke an arbitrary endpoint (HTTP POST)\n\t\t$ {{.Name}} invoke --target=\"https:\/\/my-http-handler.example.com\"\n\n\to Invoke an arbitrary endpoint (CloudEvent)\n\t\t$ {{.Name}} invoke -f=cloudevent -t=\"https:\/\/my-event-broker.example.com\"\n\n`,\n\t\tSuggestFor: []string{\"emit\", \"emti\", \"send\", \"emit\", \"exec\", \"nivoke\", \"onvoke\", \"unvoke\", \"knvoke\", \"imvoke\", \"ihvoke\", \"ibvoke\"},\n\t\tPreRunE:    bindEnv(\"path\", \"format\", \"target\", \"id\", \"source\", \"type\", \"data\", \"content-type\", \"file\", \"confirm\"),\n\t}\n\n\t\/\/ Flags\n\tcmd.Flags().StringP(\"path\", \"p\", cwd(), \"Path to the Function which should have its instance invoked.

If the Function is running\n\tboth locally and remote, the local instance will be invoked.  This behavior\n\tcan be manually overridden using the --target flag.\n\n\tFunctions are invoked with a test data structure consisting of five values:\n\t\tid:            A unique identifier for the request.\n\t\tsource:        A sender name for the request (sender).\n\t\ttype:          A type for the request.\n\t\tdata:          Data (content) for this request.\n\t\tcontent-type:  The MIME type of the value contained in 'data'.\n\n\tThe values of these parameters can be individually altered from their defaults\n\tusing their associated flags. Data can also be provided from a file using the\n\t--file flag.\n\n\tInvocation Target\n\t  The Function instance to invoke can be specified using the --target flag\n\t  which accepts the values \"local\", \"remote\", or <URL>.  By default the\n\t  local Function instance is chosen if running (see {{.Name}} run).\n\t  To explicitly target the remote (deployed) Function:\n\t    {{.Name}} invoke --target=remote\n\t  To target an arbitrary endpoint, provide a URL:\n\t    {{.Name}} invoke --target=https:\/\/myfunction.example.com\n\n\tInvocation Data\n\t  Providing a filename in the --file flag will base64 encode its contents\n\t  as the \"data\" parameter sent to the Function.  The value of --content-type\n\t  should be set to the type from the source file.  For example, the following\n\t  would send a JPEG base64 encoded in the \"data\" POST parameter:\n\t    {{.Name}} invoke --file=example.jpeg --content-type=image\/jpeg\n\n\tMessage Format\n\t  By default Functions are sent messages which match the invocation format\n\t  of the template they were created using; for example \"http\" or \"cloudevent\".\n\t  To override this behavior, use the --format (-f) flag.\n\t    {{.Name}} invoke -f=cloudevent -t=http:\/\/my-sink.my-cluster\n\nEXAMPLES\n\n\to Invoke the default (local or remote) running Function with default values\n\t  $ {{.Name}} invoke\n\n\to Run the Function locally and then invoke it with a test request:\n\t  (run in two terminals or by running the first in the background)\n\t  $ {{.Name}} run\n\t  $ {{.Name}} invoke\n\n\to Deploy and then invoke the remote Function:\n\t  $ {{.Name}} deploy\n\t  $ {{.Name}} invoke\n\n\to Invoke a remote (deployed) Function when it is already running locally:\n\t  (overrides the default behavior of preferring locally running instances)\n\t  $ {{.Name}} invoke --target=remote\n\n\to Specify the data to send to the Function as a flag\n\t  $ {{.Name}} invoke --data=\"Hello World!\"\n\n\to Send a JPEG to the Function\n\t  $ {{.Name}} invoke --file=example.jpeg --content-type=image\/jpeg\n\n\to Invoke an arbitrary endpoint (HTTP POST)\n\t\t$ {{.Name}} invoke --target=\"https:\/\/my-http-handler.example.com\"\n\n\to Invoke an arbitrary endpoint (CloudEvent)\n\t\t$ {{.Name}} invoke -f=cloudevent -t=\"https:\/\/my-event-broker.example.com\"\n\n`,\n\t\tSuggestFor: []string{\"emit\", \"emti\", \"send\", \"emit\", \"exec\", \"nivoke\", \"onvoke\", \"unvoke\", \"knvoke\", \"imvoke\", \"ihvoke\", \"ibvoke\"},\n\t\tPreRunE:    bindEnv(\"path\", \"format\", \"target\", \"id\", \"source\", \"type\", \"data\", \"content-type\", \"file\", \"confirm\"),\n\t}\n\n\t\/\/ Flags\n\tcmd.Flags().StringP(\"path\", \"p\", cwd(), \"Path to the Function which should have its instance invoked.

This allows the client\n\/\/ to actually act as a server as well.\n\/\/\n\/\/ MuxConn works using a fairly dumb multiplexing technique of simply\n\/\/ framing every piece of data sent into a prefix + data format. Streams\n\/\/ are established using a subset of the TCP protocol. Only a subset is\n\/\/ necessary since we assume ordering on the underlying RWC.\ntype MuxConn struct {\n\tcurId   uint32\n\trwc     io.ReadWriteCloser\n\tstreams map[uint32]*Stream\n\tmu      sync.RWMutex\n\twlock   sync.Mutex\n}\n\ntype muxPacketType byte\n\nconst (\n\tmuxPacketSyn muxPacketType = iota\n\tmuxPacketAck\n\tmuxPacketFin\n\tmuxPacketData\n)\n\nfunc NewMuxConn(rwc io.ReadWriteCloser) *MuxConn {\n\tm := &MuxConn{\n\t\trwc:     rwc,\n\t\tstreams: make(map[uint32]*Stream),\n\t}\n\n\tgo m.loop()\n\n\treturn m\n}\n\n\/\/ Close closes the underlying io.ReadWriteCloser.
