The selected host creates a block\n and announces it. The hosts who agree that the selected host is the block\n compiler release a heartbeat update.\n\n Once the selected host has compiled heartbeats from the majority of swarms,\n the block compiler makes another block which indicates that the swarm is\n transitioning out of this state.\n\n If this process fails, then the host should be marked as an invalid compiler\n and the next block compiler attempted, until this process fails or some other\n timeout expires.\n\n TODO: This implementation handles failure after the first block has appeared\n badly. Also the learning phase -> block compiler transition should probably\n have a pause in it and we should have a constant start time, not just 1 second\n after we started a given structure.\n\n TODO: We can actually do stage1 hashes in the nodealive message and stage1\n and 2 in the heartbeat message.

Each node sends a NodeAlive message.\n They then wait to see at least a majority of the swarms NodeAlive messages\n then they resend their NodeAlive message, to make sure that the majority of\n the swarm knows they are alive.\n\n Once the learning period has expired, rendezvous hashing is used to select\n the host which should compile the block. The selected host creates a block\n and announces it. The hosts who agree that the selected host is the block\n compiler release a heartbeat update.\n\n Once the selected host has compiled heartbeats from the majority of swarms,\n the block compiler makes another block which indicates that the swarm is\n transitioning out of this state.\n\n If this process fails, then the host should be marked as an invalid compiler\n and the next block compiler attempted, until this process fails or some other\n timeout expires.\n\n TODO: This implementation handles failure after the first block has appeared\n badly. Also the learning phase -> block compiler transition should probably\n have a pause in it and we should have a constant start time, not just 1 second\n after we started a given structure.\n\n TODO: We can actually do stage1 hashes in the nodealive message and stage1\n and 2 in the heartbeat message.

A sample configuration file can be found at\nhttps:\/\/github.com\/gokcehan\/lf\/blob\/master\/etc\/lfrc.example.\n\nPrefixes\n\nThe following command prefixes are used by lf:\n\n : read (default)\n $ read-shell\n ! read-shell-wait\n & read-shell-async\n \/ search\n ? search-back\n\nThe same evaluator is used for the command line and the configuration file. The\ndifference is that prefixes are not necessary in the command line. Instead\ndifferent modes are provided to read corresponding commands. Note that by\ndefault these modes are mapped to the prefix keys above.\n\nSyntax\n\nCharacters from \"#\" to the line end are comments and ignored.\n\nThere are three special commands for configuration.\n\n\"set\" is used to set an option which could be (1) bool (e.g. \"set hidden\", \"set\nnohidden\", \"set hidden!\") (2) int (e.g. \"set scrolloff 10\") (3) string (e.g.\n\"set sortby time\").\n\n\"map\" is used to bind a key to a command which could be (1) built-in command\n(e.g. \"map gh cd ~\") (2) custom command (e.g. \"map D trash\") (3) shell command\n(e.g. \"map i $less \"$f\"\", \"map u !du -h . | less\"). You can delete an existing\nbinding by leaving the expression empty (e.g. \"map gh\").\n\n\"cmd\" is used to define a custom command or delete an existing command by\nleaving the expression empty (e.g. \"cmd trash\").\n\nIf there is no prefix then \":\" is assumed. An explicit \":\" could be provided to\ngroup statements until a \"\\n\" occurs. This is especially useful for \"map\" and\n\"cmd\" commands. If you need multiline you can wrap statements in \"{{\" and \"}}\"\nafter the proper prefix.\n\nYank\/Delete\/Paste\n\nlf uses the underlying \"cp\" and \"mv\" shell commands for file operations. For\nthis purpose, when you \"yank\" (i.e. copy) a file, it doesn't actually copy the\nfile on the disk, but only records its name to memory. The actual file\noperation takes place when you do the \"paste\" in which case the \"cp\" command is\nused. Similarly the \"mv\" command is used for \"delete\" (i.e. cut or kill)\nfollowed by \"paste\". These traditional names (e.g. \"yank\" and \"delete\") are\npicked instead of the other common convention (e.g. copy and cut) to resemble\nthe default keybinds for these operations.\n\nCustom Commands\n\nTo wrap up let us write a shell command to move selected file(s) to trash.\n\nA first attempt to write such a command may look like this:\n\n cmd trash ${{\n mkdir -p ~\/.trash\n if [ -z $fs ]; then\n mv --backup=numbered \"$f\" $HOME\/.trash\n else\n IFS=':'; mv --backup=numbered $fs $HOME\/.trash\n fi\n }}\n\nWe check \"$fs\" to see if there are any marked files. Otherwise we just delete\nthe current file. Since this is such a common pattern, a separate \"$fx\"\nvariable is provided. We can use this variable to get rid of the conditional.\n\n cmd trash ${{\n mkdir -p ~\/.trash\n IFS=':'; mv --backup=numbered $fx $HOME\/.trash\n }}\n\nThe trash directory is checked each time the command is executed. We can move\nit outside of the command so it would only run once at startup.\n\n ${{ mkdir -p ~\/.trash }}\n\n cmd trash ${{ IFS=':'; mv --backup=numbered $fx $HOME\/.trash }}\n\nSince these are one liners, we can drop \"{{\" and \"}}\".\n\n $mkdir -p ~\/.trash\n\n cmd trash $IFS=':'; mv --backup=numbered $fx $HOME\/.trash\n\nFinally note that we set \"IFS\" variable accordingly in the command. Instead we\ncould use the \"ifs\" option to set it for all commands (e.g. \"set ifs ':'\").\nThis could be especially useful for interactive use (e.g. \"rm $fs\" would simply\nwork). This option is not set by default as things may behave unexpectedly at\nother places.\n\nOpening Files\n\nYou can use \"open-file\" command to open a file.

A sample configuration file can be found at\nhttps:\/\/github.com\/gokcehan\/lf\/blob\/master\/etc\/lfrc.example.\n\nPrefixes\n\nThe following command prefixes are used by lf:\n\n : read (default)\n $ read-shell\n ! read-shell-wait\n & read-shell-async\n \/ search\n ? search-back\n\nThe same evaluator is used for the command line and the configuration file. The\ndifference is that prefixes are not necessary in the command line. Instead\ndifferent modes are provided to read corresponding commands. Note that by\ndefault these modes are mapped to the prefix keys above.\n\nSyntax\n\nCharacters from \"#\" to the line end are comments and ignored.\n\nThere are three special commands for configuration.\n\n\"set\" is used to set an option which could be (1) bool (e.g. \"set hidden\", \"set\nnohidden\", \"set hidden!\") (2) int (e.g. \"set scrolloff 10\") (3) string (e.g.\n\"set sortby time\").\n\n\"map\" is used to bind a key to a command which could be (1) built-in command\n(e.g. \"map gh cd ~\") (2) custom command (e.g. \"map D trash\") (3) shell command\n(e.g. \"map i $less \"$f\"\", \"map u !du -h . | less\"). You can delete an existing\nbinding by leaving the expression empty (e.g. \"map gh\").\n\n\"cmd\" is used to define a custom command or delete an existing command by\nleaving the expression empty (e.g. \"cmd trash\").\n\nIf there is no prefix then \":\" is assumed. An explicit \":\" could be provided to\ngroup statements until a \"\\n\" occurs. This is especially useful for \"map\" and\n\"cmd\" commands. If you need multiline you can wrap statements in \"{{\" and \"}}\"\nafter the proper prefix.\n\nFile Operations\n\nlf uses the underlying \"cp\" and \"mv\" shell commands for file operations. For\nthis purpose, when you \"yank\" (i.e. copy) a file, it doesn't actually copy the\nfile on the disk, but only records its name to memory. The actual file\noperation takes place when you do the \"paste\" in which case the \"cp\" command is\nused. Similarly the \"mv\" command is used for \"delete\" (i.e. cut or kill)\nfollowed by \"paste\". These traditional names (e.g. \"yank\" and \"delete\") are\npicked instead of the other common convention (e.g. copy and cut) to resemble\nthe default keybinds for these operations.\n\nCustom Commands\n\nTo wrap up let us write a shell command to move selected file(s) to trash.\n\nA first attempt to write such a command may look like this:\n\n cmd trash ${{\n mkdir -p ~\/.trash\n if [ -z $fs ]; then\n mv --backup=numbered \"$f\" $HOME\/.trash\n else\n IFS=':'; mv --backup=numbered $fs $HOME\/.trash\n fi\n }}\n\nWe check \"$fs\" to see if there are any marked files. Otherwise we just delete\nthe current file. Since this is such a common pattern, a separate \"$fx\"\nvariable is provided. We can use this variable to get rid of the conditional.\n\n cmd trash ${{\n mkdir -p ~\/.trash\n IFS=':'; mv --backup=numbered $fx $HOME\/.trash\n }}\n\nThe trash directory is checked each time the command is executed. We can move\nit outside of the command so it would only run once at startup.\n\n ${{ mkdir -p ~\/.trash }}\n\n cmd trash ${{ IFS=':'; mv --backup=numbered $fx $HOME\/.trash }}\n\nSince these are one liners, we can drop \"{{\" and \"}}\".\n\n $mkdir -p ~\/.trash\n\n cmd trash $IFS=':'; mv --backup=numbered $fx $HOME\/.trash\n\nFinally note that we set \"IFS\" variable accordingly in the command. Instead we\ncould use the \"ifs\" option to set it for all commands (e.g. \"set ifs ':'\").\nThis could be especially useful for interactive use (e.g. \"rm $fs\" would simply\nwork). This option is not set by default as things may behave unexpectedly at\nother places.\n\nOpening Files\n\nYou can use \"open-file\" command to open a file. This is a special command\ncalled by \"open\" when the current file is not a directory. Normally a user maps\nthe \"open\" command to a key (default \"l\") and customize \"open-file\" command as\ndesired. You can define it just as you would define any other command.\n\n cmd open-file $IFS=':'; vim $fx\n\nIt is possible to use different command types.\n\n cmd open-file &xdg-open \"$f\"\n\nYou may want to use either file extensions or mime types with \"file\".\n\n cmd open-file ${{\n case $(file --mime-type \"$f\" -b) in\n text\/*) IFS=':'; vim $fx;;\n *) IFS=':'; for f in $fx; do xdg-open \"$f\" &> \/dev\/null & done;;\n esac\n }}\n\nlf does not come bundled with a file opener.

While this would allow them to copy the header from a message and\n\/\/ replace all the contents with valid ChaCha20Poly1305 ciphertexts, the Ed25519\n\/\/ signature will fail to verify and decryption will halt.\n\/\/\n\/\/\n\/\/ If A Rando Plays With Protobufs\n\/\/\n\/\/ The sole aspect of a message which is unauthenticated is the Protocol Buffer\n\/\/ and framing metadata. An attacker can craft a message which has protobuf\n\/\/ frames which are up to 4GiB. Grump implementations should perform hygiene\n\/\/ checks on these values, and Protocol Buffer implementations should be checked\n\/\/ for robustness to these types of attacks.\n\/\/\n\/\/ If a packet's frame is changed to, for example, elide data, the SHA-512 hash\n\/\/ will change and the packet will become invalid.\n\/\/\n\/\/\n\/\/ Design\n\/\/\n\/\/ The general design is largely informed by ECIES\n\/\/ (http:\/\/en.wikipedia.org\/wiki\/Integrated_Encryption_Scheme), in that it\n\/\/ combines a key exchange algorithm, a key derivation algorithm, and an\n\/\/ IND-CCA2 AEAD scheme.\n\/\/\n\/\/\n\/\/ Protocol Buffers\n\/\/\n\/\/ X.509 is better than nothing, but it's horrible. Grump uses Protocol Buffers,\n\/\/ which has extremely broad language support\n\/\/ (https:\/\/code.google.com\/p\/protobuf\/wiki\/ThirdPartyAddOns).\n\/\/\n\/\/\n\/\/ Curve25519 And Ed25519\n\/\/\n\/\/ These algorithms were selected because they're both fast, constant-time,\n\/\/ require entropy for key generation only, use small keys, and use safe\n\/\/ elliptic curves (http:\/\/safecurves.cr.yp.to).\n\/\/\n\/\/\n\/\/ ChaCha20Poly1305\n\/\/\n\/\/ The ChaChaPoly1305 AEAD construction was chosen because it's fast and\n\/\/ constant-time.\n\/\/\n\/\/\n\/\/ Scrypt\n\/\/\n\/\/ scrypt was chosen as a PBKDF algorithm because it's resistant to CPU-, GPU-,\n\/\/ FPGA-, and ASIC-optimized dictionary attacks.\n\/\/\n\/\/\n\/\/ SHA-512 and HKDF\n\/\/\n\/\/ These were selected as a KDF because Ed25519 already uses SHA-512.\n\/\/\n\/\/\n\/\/ Keys\n\/\/\n\/\/ A Grump private key is the combination of a Curve25519 decryption key and a\n\/\/ Ed25519 signing key. Both are stored on disk encrypted with ChaCha20Poly1305,\n\/\/ using a key derived from your passphrase via scrypt.\n\/\/\n\/\/ A Grump public key is the combination of a Curve25519 encryption key and a\n\/\/ Ed25519 verifying key.\n\/\/\n\/\/ No, there isn't any way to keep track of whose keys are whose.\n\/\/\n\/\/\n\/\/ Messages\n\/\/\n\/\/ Grump messages are a sequence of framed protobufs (little-endian, 32-bit\n\/\/ frame value, then that many bytes of protobuf).\n\/\/\n\/\/ A message starts with a header, which is contains the message key (a random\n\/\/ 256-bit key) encrypted with the shared secret for each recipient (the\n\/\/ Curve25519 ECDH shared secret, run through HKDF-SHA-512) using\n\/\/ ChaCha20Poly1305. There is no meta-data, so random values can be added here\n\/\/ to obscure the actual number of recipients.\n\/\/\n\/\/ (To decrypt a message, one simply iterates through the recipients, trying\n\/\/ each.)\n\/\/\n\/\/ After the header comes a series of packets of arbitrary sizes, which are\n\/\/ portions of the plaintext encrypted with ChaCha20Poly1305, using the SHA-512\n\/\/ hash of all previously written bytes as the authenticated data. The last\n\/\/ packet in a message is flagged as such.\n\/\/\n\/\/ The final element of a message is an Ed25519 signature of the SHA-512 hash of\n\/\/ every byte in the message which precedes the signature's frame. Any attempt\n\/\/ to modify the message will fail this verification.\npackage grump\n<|endoftext|>"} {"text":"<commit_before>\/*\nPackage syslog5424 implements syslog RFC 5424 with a completly API compatibility with the standard log.Logger\n\n\nthe simpliest way to use syslog5424 is :\n\n\n\tpackage main\n\n\timport\t(\n\t\t\"github.com\/nathanaelle\/syslog5424\"\n\t)\n\n\tfunc main() {\n\t\t\/\/ create a connection the standard error\n\t\tsl_conn, _, _ := syslog5424.Dial( \"stdio\", \"stderr:\" )\n\n\t\t\/\/ create a syslog wrapper around the connection\n\t\t\/\/ the program is named \"test-app\" and you log to LogDAEMON facility at least at LogWARNING level\n\t\tsyslog,_ := syslog5424.New( sl_conn, syslog5424.LogDAEMON|syslog5424.LogWARNING, \"test-app\" )\n\n\t\t\/\/ create a channel for the level LogERR\n\t\terr_channel\t:= syslog.Channel( syslog5424.LogERR )\n\n\t\t\/\/ get a the *log.Logger for this channel with a prefix \"ERR : \"\n\t\tlogger_err := err_channel.Logger( \"ERR : \" )\n\n\t\t\/\/ log a message through the log.Logger\n\t\tlogger_err.Print( \"doing some stuff\" )\n\t}\n\n\n\n\n\n*\/\npackage syslog5424 \/\/ import \"github.com\/nathanaelle\/syslog5424\/v2\"\n<commit_msg>correction in doc<commit_after>\/*\n\nPackage syslog5424 implements syslog RFC 5424 with a complete compatibility with the standard log.Logger API.\n\n\nthe simpliest way to use syslog5424 is :\n\n\n\tpackage main\n\n\timport\t(\n\t\t\"github.com\/nathanaelle\/syslog5424\"\n\t)\n\n\tfunc main() {\n\t\t\/\/ create a connection the standard error\n\t\tsl_conn, _, _ := syslog5424.Dial( \"stdio\", \"stderr:\" )\n\n\t\t\/\/ create a syslog wrapper around the connection\n\t\t\/\/ the program is named \"test-app\" and you log to LogDAEMON facility at least at LogWARNING level\n\t\tsyslog,_ := syslog5424.New( sl_conn, syslog5424.LogDAEMON|syslog5424.LogWARNING, \"test-app\" )\n\n\t\t\/\/ create a channel for the level LogERR\n\t\terr_channel\t:= syslog.Channel( syslog5424.LogERR )\n\n\t\t\/\/ get a the *log.Logger for this channel with a prefix \"ERR : \"\n\t\tlogger_err := err_channel.Logger( \"ERR : \" )\n\n\t\t\/\/ log a message through the log.Logger\n\t\tlogger_err.Print( \"doing some stuff\" )\n\t}\n\n\n\n\n\n*\/\npackage syslog5424 \/\/ import \"github.com\/nathanaelle\/syslog5424\/v2\"\n<|endoftext|>"} {"text":"<commit_before>\/\/ A library to create in process topologies of goroutines connected by channels.\n\/\/ Topo does boilerplate work as outlined in http:\/\/blog.golang.org\/pipelines.\n\/\/ You receive correctly connected input and output channels, leaving the\n\/\/ message processing for you while handling the plumbing.\n\/\/\n\/\/ Example Code\n\/\/\n\/\/ \tpackage main\n\/\/\n\/\/ \timport (\n\/\/ \t\t\"fmt\"\n\/\/ \t\t\"sync\"\n\/\/\n\/\/ \t\t\"github.com\/mdmarek\/topo\"\n\/\/ \t\t\"github.com\/mdmarek\/topo\/topoutil\"\n\/\/ \t)\n\/\/\n\/\/ \tconst seed = 12282\n\/\/ \tconst nworkers = 2\n\/\/\n\/\/ \tfunc main() {\n\/\/ \t\twg := new(sync.WaitGroup)\n\/\/ \t\twg.Add(nworkers)\n\/\/\n\/\/ \t\t\/\/ Create a new topo and source of streaming data from meetup.com.\n\/\/ \t\tt := topo.New(seed)\n\/\/ \t\tsource, err := topoutil.NewMeetupSource(t)\n\/\/\n\/\/ \t\tif err != nil {\n\/\/ \t\t\tfmt.Printf(\"Failed to open source: %v\\n\", err)\n\/\/ \t\t\treturn\n\/\/ \t\t}\n\/\/\n\/\/ \t\t\/\/ Shuffles messages read from the source\n\/\/ \t\t\/\/ to each output channel.\n\/\/ \t\toutputs := t.Shuffle(nworkers, source)\n\/\/\n\/\/ \t\t\/\/ Each output channel is read by one Sink, which\n\/\/ \t\t\/\/ prints to stdout the messages it receives.\n\/\/ \t\tfor i := 0;

If this succeeds then\n\/\/ we are guaranteed to have the latest value in memcache. If it fails due\n\/\/ to a CAS failure then there must have been a concurrent write to\n\/\/ memcache and now the memcache for that key is out of action for 32\n\/\/ seconds.\n\/\/\n\/\/ Note that within a transaction, much of this functionality is lost to ensure\n\/\/ datastore consistency.\n\/\/\n\/\/ dst argument must be a slice.\nfunc getMulti(cc *context, keys []*datastore.Key, dst reflect.Value) error {\n\n\tgs := newGetMultiState(keys, dst)\n\n\tif err := loadMemory(cc, gs);

The returned values\n\/\/ can be in one of three states: No entity, locked value or the acutal entity.\n\/\/\n\/\/ Actual entity case:\n\/\/ If the value from memcache is an actual entity then replensish the local\n\/\/ cache and return that entity to the caller.\n\/\/\n\/\/ Locked entity case:\n\/\/ If the value is locked then just ignore that entity and go to the datastore\n\/\/ to see if it exists.\n\/\/\n\/\/ No entity case:\n\/\/ If no entity is returned from memcache then do the following things to ensure\n\/\/ we don't accidentally update memcache with stale values.\n\/\/ 1) Lock that entity in memcache by setting memcacheLock on that entities key.\n\/\/ Note that the lock timeout is 32 seconds to cater for a datastore edge\n\/\/ case which I currently can't quite remember.\n\/\/ 2) Immediately get that entity back from memcache ensuring the compare and\n\/\/ swap ID is set.\n\/\/ 3) Get the entity from the datastore.\n\/\/ 4) Set the entity in memcache using compare and swap. If this succeeds then\n\/\/ we are guaranteed to have the latest value in memcache. If it fails due\n\/\/ to a CAS failure then there must have been a concurrent write to\n\/\/ memcache and now the memcache for that key is out of action for 32\n\/\/ seconds.\n\/\/\n\/\/ Note that within a transaction, much of this functionality is lost to ensure\n\/\/ datastore consistency.\n\/\/\n\/\/ dst argument must be a slice.\nfunc getMulti(cc *context, keys []*datastore.Key, dst reflect.Value) error {\n\n\tgs := newGetMultiState(keys, dst)\n\n\tif err := loadMemory(cc, gs);

runnning, and that slow log readers don't block task execution.\n\/\/\n\/\/ To test livelog we run a task and read the livelog while the task is running.\n\/\/ This test case does this expecting the livelog to contain a message before\n\/\/ task is resolved.\n\/\/\n\/\/ To avoid making an extremely intermittent test case, this test case uses\n\/\/ a test-server that will:\n\/\/ 1. open the livelog and read until it has read the message\n\/\/ 2. replies 200 with a response payload, once step (1) is done.\n\/\/ 3. Execute one of the following behaviors:\n\/\/ * 'close' the livelog without reading the rest of it.\n\/\/ * 'read-all' of the livelog before closing it\n\/\/ * 'leak' the livelog request not closing it until task is resolved\n\/\/\n\/\/ The test task will then:\n\/\/ 1. Print the message to log\n\/\/ 2. Ping the test-server and block waiting for the reply\n\/\/ 3. Print the test-server reply, exiting successfully if response is 200.\n\/\/\n\/\/ By greping the final log for response payload we ensure that our test-server\n\/\/ did indeed reply to the test task. By not replying from the test-server\n\/\/ until we've read the message from the livelog, we ensure that the livelog\n\/\/ works. If livelog doesn't work this should deadlock, or request should\n\/\/ timeout in the test task, instead of returning 200.\n\/\/\n\/\/ To increase test coverage we shall try with a few different message sizes\n\/\/ and behaviors for the test-server once it has replied. The behaviors\n\/\/ ensures that a blocking livelog reader doesn't block the worker, or cause\n\/\/ other undesired behavior in the worker.\nfunc TestLiveLog(t *testing.T) {\n\tif goruntime.GOOS ==

For more information and configuration options, see\n\"Deadlines\" below.\n\nNote: It is possible for Messages to be redelivered, even if Message.Ack has\nbeen called.

Please take a look at https:\/\/cloud.google.com\/pubsub\/docs\/pull#streamingpull\nfor more details on how streaming pull behaves compared to the synchronous\npull method.\n\nDeadlines\n\nThe default pubsub deadlines are suitable for most use cases, but may be\noverridden. This section describes the tradeoffs that should be considered\nwhen overriding the defaults.\n\nBehind the scenes, each message returned by the Pub\/Sub server has an\nassociated lease, known as an \"ACK deadline\".\nUnless a message is acknowledged within the ACK deadline, or the client requests that\nthe ACK deadline be extended, the message will become elegible for redelivery.\nAs a convenience, the pubsub package will automatically extend deadlines until\neither:\n * Message.Ack or Message.Nack is called, or\n * the \"MaxExtension\" period elapses from the time the message is fetched from the server.\n\nThe initial ACK deadline given to each messages defaults to 10 seconds, but may\nbe overridden during subscription creation. Selecting an ACK deadline is a\ntradeoff between message redelivery latency and RPC volume. If the pubsub\npackage fails to acknowledge or extend a message (e.g. due to unexpected\ntermination of the process), a shorter ACK deadline will generally result in\nfaster message redelivery by the Pub\/Sub system. However, a short ACK deadline\nmay also increase the number of deadline extension RPCs that the pubsub package\nsends to the server.\n\nThe default max extension period is DefaultReceiveSettings.MaxExtension, and can\nbe overridden by setting Subscription.ReceiveSettings.MaxExtension. Selecting a\nmax extension period is a tradeoff between the speed at which client code must\nprocess messages, and the redelivery delay if messages fail to be acknowledged\n(e.g. because client code neglects to do so). Using a large MaxExtension\nincreases the available time for client code to process messages. However, if\nthe client code neglects to call Message.Ack\/Nack, a large MaxExtension will\nincrease the delay before the message is redelivered.\n\nSlow Message Processing\n\nFor use cases where message processing exceeds 30 minutes, we recommend using\nthe base client in a pull model, since long-lived streams are periodically killed\nby firewalls.

The initial ACK\ndeadline given to messages is 10s. The period between extensions, as well as the\nlength of the extension, automatically adjust depending on the time it takes to ack\nmessages, up to 10m. This has the effect that subscribers that process messages\nquickly have their message ack deadlines extended for a short amount, whereas\nsubscribers that process message slowly have their message ack deadlines extended\nfor a large amount. The net effect is fewer RPCs sent from the client library.\n\nFor example, consider a subscriber that takes 3 minutes to process each message.\nSince the library has already recorded several 3 minute \"time to ack\"s in a\npercentile distribution, future message extensions are sent with a value of 3\nminutes, every 3 minutes. Suppose the application crashes 5 seconds after the\nlibrary sends such an extension: the Pub\/Sub server would wait the remaining\n2m55s before re-sending the messages out to other subscribers.\n\nSlow Message Processing\n\nFor use cases where message processing exceeds 30 minutes, we recommend using\nthe base client in a pull model, since long-lived streams are periodically killed\nby firewalls.

File\n}\n\n\/*\npdf.Indirect is one of the most important and most complex\nobject types. Whereas \"direct\" objects are rendered the same way on\nevery output stream, a pdf.Indirect is rendered differently\ndepending on which file it is associated with. There is always an\nunderlying \"direct object\" that is written to one or more PDF files,\nwhere it is assigned both an object and generation number. When the\nSerialize() method is invoked, a pdf.Indirect is rendered as an\nindirect reference (for example, \"10 1 R\"). There are several\nuse-cases.\n\nUSE-CASE 1: A pdf.Indirect object is created, its Serialize() method\nis invoked for one or more output files, then its Write() method is\ninvoked with its underlying direct object. The PDF reference suggests\nthat a reference is sometimes written before the information required\nfor the object being referenced is available. An example from the PDF\nreference is using an indirect object reference for the length of the\nstream before writing the stream, presumably so you can write the\nstream dictionary at a moment when the length of the stream is\nunknown. The stream length is written as a separate object after the\nstream is completed when the length is known with certainty. This\nparticular example is somewhat contrived. With the size of memory in\nmodern computers it's difficult to imagine a scenario where a stream\ncannot be written to a buffer in its entirely and written as an atomic\nstream object. Nonetheless, a pdf.Indirect object supports this\nprogramming style where object references are written to a file before\nthe objects they refer to have been completely defined. We do *not*\nsupport this model with streams, however, and *do* require streams to\nbe completed in memory before any portion of the strean is written to\na file. A pdf.Indirect can be written before the direct object it\nreferences has been defined. A pdf.Indirect obtains and reserves an\nobject number whenever it is written to a file, whether or not the\nobject being referenced has yet been specified. Eventually, the\nWrite() method must be called passing the object being referenced.\nAt that moment, the object being referenced is written to all files to\nwhich the pdf.Indirect was written. If the pdf.Indirect is\nsubsequently added to additional files, the Write()ed object must\nalso written to those files. This, however, would require either\nretaining a reference in memory indefinitely (bad) or reading it from\none of the files where it is known to exist (reading is not yet\nimplemented; it must be read as opposed to just copied because any\nindirect references contained within it also need to be read and added\nto the file accordingly). For the time being, we elect not to keep\nreferences in memory. Until parsing is implemented, indirect objects\nmay be explicitly bound to files either (1) by using ObjectNumber()\nprior to calling Write or (2) by calling pdf.File.AddObject().\nSerialize()ing a pdf.Indirect to a new file after calling Write()\nwithout an earlier call to Serialize() or ObjectNumber() will\ngenerate an error. The complete list of files that will contain the\nrefence must be known when Write() is called.\n\nThe call to ObjectNumber() is handled transparently and automatically\nfor forward references. The client need not call it explicitly. A\ncall to ObjectNumber() is required, however, for indirect objects that\nare backward references. An alternative way to obtain a backward\nreference is using the return value from pdf.File.AddObject(). The\nreference returned by pdf.File.AddObject() is bound only to one file.\n\nUSE-CASE 2: A pdf.Indirect is created based on a finished direct\nobject. This is essentially the same as use-case 1. An object is\nconstructed and Write() is called immediately. Subsequent invocations\nof Serialize() on files where it doesn't already exist cause it to be\nadded to that file. As with USE-CASE 1, this requires either\nretaining a reference in memory indefinitely (bad) or reading from one\nof the files where it is known to exist (not yet implemented). For\nthe time being, we elect not to keep references in memory. Until\nparsing is implemented, so Serialize()ing a pdf.Indirect to a file\nafter calling Write() is an error.\n\nUSE-CASE 3: A pdf.Indirect is constructed when a token of the form \"10\n1 R\" is read from file X. The underlying direct object is unknown at\nthat moment, but it exists in X. Since the object exists statically\nin X, it is considered to have been finalized. If the same object is\nSerialize()'ed to file Y, then it should immediately be added to file\nY. The objects contents are obtained from X.\n\nPOSSIBLE TEMPORARY BEHAVIOR: The referenced object is retained by the\npdf.Indirect so that it can be \"dereferenced\" or written to additional\nfiles. In future versions that are able to parse PDF files, the\nobject may be discarded from memory once written and read back from\ndisk if it is dererenced or written to another file. Even better\nwould be a weak-reference to the object, but weak references are not\nimplemented in Go.\n\n*\/\n\n\/\/ NewIndirect is the constructor for Indirect objects.

You\n\/\/ start by creating a Navigator with a base URI, then Follow the links\n\/\/ exposed by the API until you reach the place where you want to perform\n\/\/ an action.\n\/\/\n\/\/ For example, to request an API exposed at api.example.com and follow a\n\/\/ link named products and GET the resulting page you'd do this:\n\/\/\n\/\/ res, err := Navigator(\"http:\/\/api.example.com\").\n\/\/ Follow(\"products\").\n\/\/ Get()\n\/\/\n\/\/ To do the same thing but POST to the products page, you'd do this:\n\/\/\n\/\/ res, err := Navigator(\"http:\/\/api.example.com\").\n\/\/ Follow(\"products\").\n\/\/ Post(\"application\/json\", someContent)\n\/\/\n\/\/ Multiple links followed in sequence.\n\/\/\n\/\/ res, err := Navigator(\"http:\/\/api.example.com\").\n\/\/ Follow(\"products\").\n\/\/ Follow(\"next\")\n\/\/ Get()\n\/\/\n\/\/ Links can also be expanded with Followf if they are URI templates.\n\/\/\n\/\/ res, err := Navigator(\"http:\/\/api.example.com\").\n\/\/ Follow(\"products\").\n\/\/ Followf(\"page\", halgo.P{\"number\": 10})\n\/\/ Get()\n\/\/\n\/\/ Navigation of relations is lazy. Requests will only be triggered when\n\/\/ you execute a method which returns a result. For example, this doesn't\n\/\/ perform any HTTP requests.\n\/\/\n\/\/ Navigator(\"http:\/\/api.example.com\").\n\/\/ Follow(\"products\")\n\/\/\n\/\/ It's only when you add a call to Get, Post, PostForm, Patch, or\n\/\/ Unmarshal to the end will any requests be triggered.\n\/\/\n\/\/ By default a Navigator will use http.DefaultClient as its mechanism for\n\/\/ making HTTP requests.

To parse a config\nfile, the user creates a ConfigVars struct and registers every variable in the\nconfig file with it. Registration requires 1) the variable name, 2) a\ndefault value, and 3) a location to write the variable to.\n\nConfig files have two parse with this package have two parts, a title and a\nbody. The title specifies the type of config file an the body contains\nVariable = Value pairs. The title ensures that when a project has multiple\nconfig files the wrong one isn't read by mistake.\n\nHere is an example configuration file that collects information about\nmy cat:\n\n # Title\n [cat_info]\n\n # Body:\n\tCatName = Bob\n\tFurColors = White, Black\n\tAge = 7.5 # Inline comments are okay, too.\n\tPaws = 4\n\nHere is an example of using the parse package to parse this type of config\nfile.\n\n\ttype CatInfo struct {\n\t\tCatName string\n\t\tFurColors []string\n\t\tAge float\n\t\tPaws, Tails int\n\t}\n\n\tinfo := new(CatInfo)\n\n vars := ConfigVars(\"cat_info\")\n vars.String(&info.CatName, \"CatName\", \"\")\n vars.Strings(&info.FurColors, \"FurColors\", []string{})\n vars.Float(&info.Age, \"Age\", -1)\n vars.Int(&info.Paws, \"Paws\", 4)\n vars.Int(&info.Tail, \"Tail\", 1)\n\n \/\/ Then, once a file has been provided\n\n err := ReadConfig(\"my_cat.config\", vars)\n if err != nil {\n \/\/ Handle error\n }\n\nA careful read of the above example will show that the supplied config file\ndoes not consider the config file missing one or more files an error. This will\nbe annoying in some cases, but is usually the desired behavior. You will need to\nexplicitly check for variables that have not been set.\n\nFor additional examples, see the usage in config_test.go\n*\/\npackage parse\n\nimport

To parse a config\nfile, the user creates a ConfigVars struct and registers every variable in the\nconfig file with it. Registration requires 1) the variable name, 2) a\ndefault value, and 3) a location to write the variable to.\n\nConfig files have two parse with this package have two parts, a title and a\nbody. The title specifies the type of config file an the body contains\nVariable = Value pairs. The title ensures that when a project has multiple\nconfig files the wrong one isn't read by mistake.\n\nHere is an example configuration file that collects information about\nmy cat:\n\n # Title\n [cat_info]\n\n # Body:\n\tCatName = Bob\n\tFurColors = White, Black\n\tAge = 7.5 # Inline comments are okay, too.\n\tPaws = 4\n\nHere is an example of using the parse package to parse this type of config\nfile.\n\n\ttype CatInfo struct {\n\t\tCatName string\n\t\tFurColors []string\n\t\tAge float\n\t\tPaws, Tails int\n\t}\n\n\tinfo := new(CatInfo)\n\n vars := ConfigVars(\"cat_info\")\n vars.String(&info.CatName, \"CatName\", \"\")\n vars.Strings(&info.FurColors, \"FurColors\", []string{})\n vars.Float(&info.Age, \"Age\", -1)\n vars.Int(&info.Paws, \"Paws\", 4)\n vars.Int(&info.Tail, \"Tail\", 1)\n\n \/\/ Then, once a file has been provided\n\n err := ReadConfig(\"my_cat.config\", vars)\n if err != nil {\n \/\/ Handle error\n }\n\nA careful read of the above example will show that the supplied config file\ndoes not consider the config file missing one or more files an error. This will\nbe annoying in some cases, but is usually the desired behavior. You will need to\nexplicitly check for variables that have not been set.\n\nFor additional examples, see the usage in config_test.go\n*\/\npackage parse\n\nimport

First, it\nallows you to specify flexible patterns, including routes with named parameters\nand regular expressions. Second, it allows you to write reconfigurable\nmiddleware stacks. And finally, it allows you to attach additional context to\nrequests, in a manner that can be manipulated by both compliant middleware and\nhandlers.\n\nA usage example:\n\n\tm := web.New()\n\nUse your favorite HTTP verbs and the interfaces you know and love from net\/http:\n\n\tvar legacyFooHttpHandler http.Handler \/\/ From elsewhere\n\tm.Get(\"\/foo\", legacyFooHttpHandler)\n\tm.Post(\"\/bar\", func(w http.ResponseWriter, r *http.Request) {\n\t\tw.Write([]byte(\"Hello world!\"))\n\t})\n\nBind parameters using either named captures or regular expressions:\n\n\tm.Get(\"\/hello\/:name\", func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tfmt.Fprintf(w, \"Hello, %s!\", c.URLParams[\"name\"])\n\t})\n\tpattern := regexp.MustCompile(`^\/ip\/(?P<ip>(?:\\d{1,3}\\.){3}\\d{1,3})$`)\n\tm.Get(pattern, func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tfmt.Fprintf(w, \"Info for IP address %s:\", c.URLParams[\"ip\"])\n\t})\n\nMiddleware are functions that wrap http.Handlers, just like you'd use with raw\nnet\/http. Middleware functions can optionally take a context parameter, which\nwill be threaded throughout the middleware stack and to the final handler, even\nif not all of the intervening middleware or handlers support contexts.\nMiddleware are encouraged to use the Env parameter to pass request-scoped data\nto other middleware and to the final handler:\n\n\tfunc LoggerMiddleware(h http.Handler) http.Handler {\n\t\thandler := func(w http.ResponseWriter, r *http.Request) {\n\t\t\tlog.Println(\"Before request\")\n\t\t\th.ServeHTTP(w, r)\n\t\t\tlog.Println(\"After request\")\n\t\t}\n\t\treturn http.HandlerFunc(handler)\n\t}\n\tfunc AuthMiddleware(c *web.C, h http.Handler) http.Handler {\n\t\thandler := func(w http.ResponseWriter, r *http.Request) {\n\t\t\tif cookie, err := r.Cookie(\"user\"); err == nil {\n\t\t\t\tc.Env[\"user\"] = cookie.Value\n\t\t\t}\n\t\t\th.ServeHTTP(w, r)\n\t\t}\n\t\treturn http.HandlerFunc(handler)\n\t}\n\n\t\/\/ This makes the AuthMiddleware above a little cleaner\n\tm.Use(middleware.EnvInit)\n\tm.Use(AuthMiddleware)\n\tm.Use(LoggerMiddleware)\n\tm.Get(\"\/baz\", func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tif user, ok := c.Env[\"user\"].(string); ok {\n\t\t\tw.Write([]byte(\"Hello \" + user))\n\t\t} else {\n\t\t\tw.Write([]byte(\"Hello Stranger!\"))\n\t\t}\n\t})\n*\/\npackage web\n\nimport (\n\t\"net\/http\"\n)\n\n\/*\nC is a request-local context object which is threaded through all compliant\nmiddleware layers and given to the final request handler.\n*\/\ntype C struct {\n\t\/\/ URLParams is a map of variables extracted from the URL (typically\n\t\/\/ from the path portion) during routing.

In order to provide an\nexpressive API, this type is an alias for interface{} (that is named for the\npurposes of documentation), however only the following concrete types are\naccepted:\n\t- types that implement Pattern\n\t- string, which is interpreted as a Sinatra-like URL pattern. In\n\t particular, the following syntax is recognized:\n\t\t- a path segment starting with with a colon will match any\n\t\t string placed at that position. e.g., \"\/:name\" will match\n\t\t \"\/carl\", binding \"name\" to \"carl\".\n\t\t- a pattern ending with \"\/*\" will match any route with that\n\t\t prefix. For instance, the pattern \"\/u\/:name\/*\" will match\n\t\t \"\/u\/carl\/\" and \"\/u\/carl\/projects\/123\", but not \"\/u\/carl\"\n\t\t (because there is no trailing slash).

First, it\nallows you to specify flexible patterns, including routes with named parameters\nand regular expressions. Second, it allows you to write reconfigurable\nmiddleware stacks. And finally, it allows you to attach additional context to\nrequests, in a manner that can be manipulated by both compliant middleware and\nhandlers.\n\nA usage example:\n\n\tm := web.New()\n\nUse your favorite HTTP verbs and the interfaces you know and love from net\/http:\n\n\tvar existingHTTPHandler http.Handler \/\/ From elsewhere\n\tm.Get(\"\/foo\", existingHTTPHandler)\n\tm.Post(\"\/bar\", func(w http.ResponseWriter, r *http.Request) {\n\t\tw.Write([]byte(\"Hello world!\"))\n\t})\n\nBind parameters using either named captures or regular expressions:\n\n\tm.Get(\"\/hello\/:name\", func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tfmt.Fprintf(w, \"Hello, %s!\", c.URLParams[\"name\"])\n\t})\n\tpattern := regexp.MustCompile(`^\/ip\/(?P<ip>(?:\\d{1,3}\\.){3}\\d{1,3})$`)\n\tm.Get(pattern, func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tfmt.Fprintf(w, \"Info for IP address %s:\", c.URLParams[\"ip\"])\n\t})\n\nMiddleware are functions that wrap http.Handlers, just like you'd use with raw\nnet\/http. Middleware functions can optionally take a context parameter, which\nwill be threaded throughout the middleware stack and to the final handler, even\nif not all of the intervening middleware or handlers support contexts.\nMiddleware are encouraged to use the Env parameter to pass request-scoped data\nto other middleware and to the final handler:\n\n\tfunc LoggerMiddleware(h http.Handler) http.Handler {\n\t\thandler := func(w http.ResponseWriter, r *http.Request) {\n\t\t\tlog.Println(\"Before request\")\n\t\t\th.ServeHTTP(w, r)\n\t\t\tlog.Println(\"After request\")\n\t\t}\n\t\treturn http.HandlerFunc(handler)\n\t}\n\tfunc AuthMiddleware(c *web.C, h http.Handler) http.Handler {\n\t\thandler := func(w http.ResponseWriter, r *http.Request) {\n\t\t\tif cookie, err := r.Cookie(\"user\"); err == nil {\n\t\t\t\tc.Env[\"user\"] = cookie.Value\n\t\t\t}\n\t\t\th.ServeHTTP(w, r)\n\t\t}\n\t\treturn http.HandlerFunc(handler)\n\t}\n\n\t\/\/ This makes the AuthMiddleware above a little cleaner\n\tm.Use(middleware.EnvInit)\n\tm.Use(AuthMiddleware)\n\tm.Use(LoggerMiddleware)\n\tm.Get(\"\/baz\", func(c web.C, w http.ResponseWriter, r *http.Request) {\n\t\tif user, ok := c.Env[\"user\"].(string); ok {\n\t\t\tw.Write([]byte(\"Hello \" + user))\n\t\t} else {\n\t\t\tw.Write([]byte(\"Hello Stranger!\"))\n\t\t}\n\t})\n*\/\npackage web\n\nimport (\n\t\"net\/http\"\n)\n\n\/*\nC is a request-local context object which is threaded through all compliant\nmiddleware layers and given to the final request handler.\n*\/\ntype C struct {\n\t\/\/ URLParams is a map of variables extracted from the URL (typically\n\t\/\/ from the path portion) during routing.

Note that this is just for diagnostic purposes,\n\t\/\/ we normally translate input\/output to\/from UTF-8, regardless of\n\t\/\/ what the user's environment is.\n\tCharacterSet() string\n\n\t\/\/ RegisterRuneFallback adds a fallback for runes that are not\n\t\/\/ part of the character set -- for example one could register\n\t\/\/ o as a fallback for ø. This should be done cautiously for\n\t\/\/ characters that might be displayed ordinarily in language\n\t\/\/ specific text -- characters that could change the meaning of\n\t\/\/ written text would be dangerous. The intention here is to\n\t\/\/ facilitate fallback characters in pseudo-graphical applications.\n\t\/\/\n\t\/\/ If the terminal has fallbacks already in place via an alternate\n\t\/\/ character set, those are used in preference. Also, standard\n\t\/\/ fallbacks for graphical characters in the alternate character set\n\t\/\/ terminfo string are registered implicitly.\n\t\/\/\n\t\/\/ The display string should be the same width as original rune.\n\t\/\/ This makes it possible to register two character replacements\n\t\/\/ for full width East Asian characters, for example.\n\t\/\/\n\t\/\/ It is recommended that replacement strings consist only of\n\t\/\/ 7-bit ASCII, since other characters may not display everywhere.\n\tRegisterRuneFallback(r rune, subst string)\n\n\t\/\/ UnregisterRuneFallback unmaps a replacement. It will unmap\n\t\/\/ the implicit ASCII replacements for alternate characters as well.\n\t\/\/ When an unmapped char needs to be displayed, but no suitable\n\t\/\/ glyph is available, '?' is emitted instead. It is not possible\n\t\/\/ to \"disable\" the use of alternate characters that are supported\n\t\/\/ by your terminal except by changing the terminal database.\n\tUnregisterRuneFallback(r rune)\n\n\t\/\/ CanDisplay returns true if the given rune can be displayed on\n\t\/\/ this screen. Note that this is a best-guess effort -- whether\n\t\/\/ your fonts support the character or not may be questionable.\n\t\/\/ Mostly this is for folks who work outside of Unicode.\n\t\/\/\n\t\/\/ If checkFallbacks is true, then if any (possibly imperfect)\n\t\/\/ fallbacks are registered, this will return true. This will\n\t\/\/ also return true if the terminal can replace the glyph with\n\t\/\/ one that is visually indistinguishable from the one requested.\n\tCanDisplay(r rune, checkFallbacks bool) bool\n\n\t\/\/ Resize does nothing, since it's generally not possible to\n\t\/\/ ask a screen to resize, but it allows the Screen to implement\n\t\/\/ the View interface.\n\tResize(int, int, int, int)\n\n\t\/\/ HasKey returns true if the keyboard is believed to have the\n\t\/\/ key. In some cases a keyboard may have keys with this name\n\t\/\/ but no support for them, while in others a key may be reported\n\t\/\/ as supported but not actually be usable (such as some emulators\n\t\/\/ that hijack certain keys). Its best not to depend to strictly\n\t\/\/ on this function, but it can be used for hinting when building\n\t\/\/ menus, displayed hot-keys, etc. Note that KeyRune (literal\n\t\/\/ runes) is always true.\n\tHasKey(Key) bool\n\n\t\/\/ Suspend pauses input and output processing. It also restores the\n\t\/\/ terminal settings to what they were when the application started.\n\t\/\/ This can be used to, for example, run a sub-shell.\n\tSuspend() error\n\n\t\/\/ Resume resumes after Suspend().\n\tResume() error\n\n\t\/\/ Beep attempts to sound an OS-dependent audible alert and returns an error\n\t\/\/ when unsuccessful.\n\tBeep() error\n}\n\n\/\/ NewScreen returns a default Screen suitable for the user's terminal\n\/\/ environment.\nfunc NewScreen() (Screen, error) {\n\t\/\/ Windows is happier if we try for a console screen first.\n\tif s, _ := NewConsoleScreen(); s != nil {\n\t\treturn s, nil\n\t} else if s, e := NewTerminfoScreen(); s != nil {\n\t\treturn s, nil\n\t} else {\n\t\treturn nil, e\n\t}\n}\n\n\/\/ MouseFlags are options to modify the handling of mouse events.\n\/\/ Actual events can be ORed together.\ntype MouseFlags int\n\nconst (\n\tMouseButtonEvents = MouseFlags(1) \/\/ Click events only\n\tMouseDragEvents = MouseFlags(2) \/\/ Click-drag events (includes button events)\n\tMouseMotionEvents = MouseFlags(4) \/\/ All mouse events (includes click and drag events)\n)\n\n\/\/ CursorStyle represents a given cursor style, which can include the shape and\n\/\/ whether the cursor blinks or is solid.

Note that in the above example, x can\nstill be freely modified.\n\nLikewise, to freeze a slice:\n\n\txs := []int{1, 2, 3}\n\txs = freeze.Slice(xs).([]int)\n\tprintln(xs[0]) \/\/ ok; prints 1\n\txs[0]++ \/\/ not ok; panics\n\nIt may not be immediately obvious why these functions return a value that must\nbe reassigned. The reason is that we are allocating new memory, and therefore\nthe pointer must be updated. The same is true of the built-in append function.\nWell, not quite; if a slice has greater capacity than length, then append will\nuse that memory. For the same reason, appending to a frozen slice with spare\ncapacity will trigger a panic.\n\nCurrently, only Unix is supported. Windows support is not planned, because it\ndoesn't support a syscall analogous to mprotect.\n*\/\npackage freeze\n\nimport (\n\t\"reflect\"\n\t\"runtime\"\n\t\"unsafe\"\n\n\t\"golang.org\/x\/sys\/unix\"\n)\n\n\/\/ Pointer freezes v, which must be a pointer.

If the majority of remote clock are correct, then\n\/\/ their intervals should overlap over some region, which should include the\n\/\/ true offset from the cluster time. This algorithm returns this region.\n\/\/\n\/\/ If an interval cannot be found, an error is returned, indicating that\n\/\/ a majority of remote node offset intervals do not overlap the cluster time.\nfunc (r *RemoteClockMonitor) findOffsetInterval() (clusterOffsetInterval, error) {\n\tendpoints := r.buildEndpointList()\n\tsort.Sort(endpoints)\n\tnumClocks := len(endpoints) \/ 2\n\tif log.V(1) {\n\t\tlog.Infof(\"finding offset interval for monitorInterval: %s, numOffsets %d\",\n\t\t\tmonitorInterval, numClocks)\n\t}\n\tif numClocks == 0 {\n\t\treturn clusterOffsetInterval{\n\t\t\tlowerbound: 0,\n\t\t\tupperbound: 0,\n\t\t}, nil\n\t}\n\n\tbest := 0\n\tcount := 0\n\tvar lowerbound int64\n\tvar upperbound int64\n\n\t\/\/ Find the interval which the most offset intervals overlap.\n\tfor i, endpoint := range endpoints {\n\t\tcount -= endpoint.endType\n\t\tif count > best {\n\t\t\tbest = count\n\t\t\tlowerbound = endpoint.offset\n\t\t\t\/\/ Note the endType of the last endpoint is +1, so count < best.\n\t\t\t\/\/ Thus this code will never run when i = len(endpoint)-1.\n\t\t\tupperbound = endpoints[i+1].offset\n\t\t}\n\t}\n\n\t\/\/ Indicates that fewer than a majority of connected remote clocks seem to\n\t\/\/ encompass the central offset from the cluster, an error condition.\n\tif best <= numClocks\/2 {\n\t\treturn clusterOffsetInterval{\n\t\t\t\tlowerbound: math.MaxInt64,\n\t\t\t\tupperbound: math.MaxInt64,\n\t\t\t}, &majorityIntervalNotFoundError{\n\t\t\t\tendpoints: endpoints,\n\t\t\t}\n\t}\n\n\t\/\/ A majority of offset intervals overlap at this interval, which should\n\t\/\/ contain the true cluster offset.\n\treturn clusterOffsetInterval{\n\t\tlowerbound: lowerbound,\n\t\tupperbound: upperbound,\n\t}, nil\n}\n\n\/\/ buildEndpointList() takes all the RemoteOffsets that are in the monitor, and\n\/\/ turns these offsets into intervals which should encompass this node's true\n\/\/ offset from the cluster time. It returns a list including the two endpoints\n\/\/ of each interval.\n\/\/\n\/\/ As a side effect, any RemoteOffsets that haven't been\n\/\/ updated since the last monitoring are removed. (Side effects are nasty, but\n\/\/ prevent us from running through the list an extra time under a lock).\n\/\/\n\/\/ A RemoteOffset r is represented by this interval:\n\/\/ [r.Offset - r.Uncertainty - MaxOffset, r.Offset + r.Uncertainty + MaxOffset],\n\/\/ where MaxOffset is the furthest a node's clock can deviate from the cluster\n\/\/ time. While the offset between this node and the remote time is actually\n\/\/ within [r.Offset - r.Uncertainty, r.Offset + r.Uncertainty], we also must expand the\n\/\/ interval by MaxOffset. This accounts for the fact that the remote clock is at\n\/\/ most MaxOffset distance from the cluster time. Thus the expanded interval\n\/\/ ought to contain this node's offset from the true cluster time, not just the\n\/\/ offset from the remote clock's time.\nfunc (r *RemoteClockMonitor) buildEndpointList() endpointList {\n\tr.mu.Lock()\n\tdefer r.mu.Unlock()\n\n\tendpoints := make(endpointList, 0, len(r.offsets)*2)\n\tfor addr, o := range r.offsets {\n\t\t\/\/ Remove anything that hasn't been updated since the last time offest\n\t\t\/\/ was measured.

Batching is triggered based\n\/\/ on a maximum number items in a batch, and\/or based on a timeout for how long\n\/\/ a batch waits before it is dispatched. For example if you're willing to wait\n\/\/ for a maximum of X duration, you can just set BatchTimeout and keep adding\n\/\/ things. Or if you don't care about how long you wait, just set MaxBatchSize\n\/\/ and it will only fire when the batch is filled. For best results set both.\n\/\/\n\/\/ This library provides a component that is intended to be used in a hidden\n\/\/ fashion. This is in your best interest in order to avoid unnecessary\n\/\/ coupling. You will typically achieve this by ensuring your implementation of\n\/\/ muster.Batch and the use of muster.Client are private.\npackage muster\n\nimport (\n\t\"errors\"\n\t\"sync\"\n\t\"time\"\n)\n\nvar errZeroBoth = errors.New(\n\t\"muster: MaxBatchSize and BatchTimeout can't both be zero\",\n)\n\n\/\/ The notifier is used to indicate to the Client when a batch has finished\n\/\/ processing.\ntype Notifier interface {\n\t\/\/ Calling Done will indicate the batch has finished processing.\n\tDone()\n}\n\n\/\/ Represents a single batch where items will be added and Fire will be called\n\/\/ exactly once.

If\n\/\/ nothing went wrong, a nil error will be returned. If a spec file was\n\/\/ identified, it will also be returned. Otherwise, a nil spec will be returned.\n\/\/\n\/\/ Spec files can be specified in a variety of ways.

For example, for module:\n\/\/\n\/\/\t\/path\/to\/foo\/bar\/baz\/__init__.py\n\/\/\t\/path\/to\/foo\/bar\/__init__.py\n\/\/\t\/path\/to\/foo\/__init__.py\n\/\/\t\/path\/to\/foo.vpython\n\/\/\n\/\/ LoadForScript will first look at \"\/path\/to\/foo\/bar\/baz\", then walk upwards\n\/\/ until it either hits a directory that doesn't contain an \"__init__.py\" file,\n\/\/ or finds the ES path. In this case, for module \"foo.bar.baz\", it will\n\/\/ identify \"\/path\/to\/foo.vpython\" as the ES file for that module.\n\/\/\n\/\/ Inline\n\/\/ ======\n\/\/\n\/\/ LoadForScript scans through the contents of the file at path and attempts to\n\/\/ load specification boundaries.\n\/\/\n\/\/ If the file at path does not exist, or if the file does not contain spec\n\/\/ guards, a nil spec will be returned.\n\/\/\n\/\/ The embedded specification is a text protobuf embedded within the file. To\n\/\/ parse it, the file is scanned line-by-line for a beginning and ending guard.\n\/\/ The content between those guards is minimally processed, then interpreted as\n\/\/ a text protobuf.\n\/\/\n\/\/\t[VPYTHON:BEGIN]\n\/\/\twheel {\n\/\/\t path: ...\n\/\/\t version: ...\n\/\/\t}\n\/\/\t[VPYTHON:END]\n\/\/\n\/\/ To allow VPYTHON directives to be embedded in a language-compatible manner\n\/\/ (with indentation, comments, etc.), the processor will identify any common\n\/\/ characters preceding the BEGIN and END clauses. If they match, those\n\/\/ characters will be automatically stripped out of the intermediate lines. This\n\/\/ can be used to embed the directives in comments:\n\/\/\n\/\/\t\/\/ [VPYTHON:BEGIN]\n\/\/\t\/\/ wheel {\n\/\/\t\/\/ path: ...\n\/\/\t\/\/ version: ...\n\/\/\t\/\/ }\n\/\/\t\/\/ [VPYTHON:END]\n\/\/\n\/\/ In this case, the \"\/\/ \" characters will be removed.\n\/\/\n\/\/ Common\n\/\/ ======\n\/\/\n\/\/ LoadForScript will examine successive parent directories starting from the\n\/\/ script's location, looking for a file named in CommonSpecNames.

If\n\/\/ nothing went wrong, a nil error will be returned. If a spec file was\n\/\/ identified, it will also be returned. Otherwise, a nil spec will be returned.\n\/\/\n\/\/ Spec files can be specified in a variety of ways.

For example, for module:\n\/\/\n\/\/\t\/path\/to\/foo\/bar\/baz\/__init__.py\n\/\/\t\/path\/to\/foo\/bar\/__init__.py\n\/\/\t\/path\/to\/foo\/__init__.py\n\/\/\t\/path\/to\/foo.vpython\n\/\/\n\/\/ LoadForScript will first look at \"\/path\/to\/foo\/bar\/baz\", then walk upwards\n\/\/ until it either hits a directory that doesn't contain an \"__init__.py\" file,\n\/\/ or finds the ES path. In this case, for module \"foo.bar.baz\", it will\n\/\/ identify \"\/path\/to\/foo.vpython\" as the ES file for that module.\n\/\/\n\/\/ Inline\n\/\/ ======\n\/\/\n\/\/ LoadForScript scans through the contents of the file at path and attempts to\n\/\/ load specification boundaries.\n\/\/\n\/\/ If the file at path does not exist, or if the file does not contain spec\n\/\/ guards, a nil spec will be returned.\n\/\/\n\/\/ The embedded specification is a text protobuf embedded within the file. To\n\/\/ parse it, the file is scanned line-by-line for a beginning and ending guard.\n\/\/ The content between those guards is minimally processed, then interpreted as\n\/\/ a text protobuf.\n\/\/\n\/\/\t[VPYTHON:BEGIN]\n\/\/\twheel {\n\/\/\t path: ...\n\/\/\t version: ...\n\/\/\t}\n\/\/\t[VPYTHON:END]\n\/\/\n\/\/ To allow VPYTHON directives to be embedded in a language-compatible manner\n\/\/ (with indentation, comments, etc.), the processor will identify any common\n\/\/ characters preceding the BEGIN and END clauses.

Note that deploying from\na local repository is deprecated in favour of deploying from a path.\n\nDeploying from a path or local repository is intended to suit the workflow of a charm\nauthor working on a single client machine; use of this deployment method from\nmultiple clients is not supported and may lead to confusing behaviour. Each\nlocal charm gets uploaded with the revision specified in the charm, if possible,\notherwise it gets a unique revision (highest in state + 1).\n\nWhen deploying from a path, the --path flag is used to specify the location from\nwhich to load the updated charm. Note that the directory containing the charm must\nmatch what was originally used to deploy the charm as a superficial check that the\nupdated charm is compatible.\n\nResources may be uploaded at upgrade time by specifying the --resource flag.\nFollowing the resource flag should be name=filepath pair.

The new charm's URL and revision are inferred as\nthey would be when running a deploy command.\n\nPlease note that --switch is dangerous, because juju only has limited\ninformation with which to determine compatibility; the operation will succeed,\nregardless of potential havoc, so long as the following conditions hold:\n\n- The new charm must declare all relations that the service is currently\nparticipating in.\n- All config settings shared by the old and new charms must\nhave the same types.\n\nThe new charm may add new relations and configuration settings.\n\n--switch and --path are mutually exclusive.\n\n--path and --revision are mutually exclusive. The revision of the updated charm\nis determined by the contents of the charm at the specified path.\n\n--switch and --revision are mutually exclusive. To specify a given revision\nnumber with --switch, give it in the charm URL, for instance \"cs:wordpress-5\"\nwould specify revision number 5 of the wordpress charm.\n\nUse of the --force-units flag is not generally recommended; units upgraded while in an\nerror state will not have upgrade-charm hooks executed, and may cause unexpected\nbehavior.\n`\n\nfunc (c *upgradeCharmCommand) Info()

to access needed flags when you are testing.\n\/\/\n\/\/ Property file\n\/\/\n\/\/ \"NewTestFlags()\" has two way to load property file:\n\/\/\n\/\/ \tOWL_TEST_PROPS_FILE - Environment Variable\n\/\/ \t\"-owl.test.propfile\" - flag of \"go test\"\n\/\/\n\/\/ Entry Environment Variables\n\/\/\n\/\/ Following environment variables are supported when calling \"NewTestFlags()\".\n\/\/\n\/\/ \tOWL_TEST_PROPS - As same as \"-owl.test\"\n\/\/ \tOWL_TEST_PROPS_SEP - As same as \"-owl.test.sep\"\n\/\/\n\/\/ Entry Flags\n\/\/\n\/\/ There are only two flags of Golang needed:\n\/\/\n\/\/ \t-owl.test=<properties>\n\/\/ \t-owl.test.sep=<separator for properties>\n\/\/\n\/\/ The format used by \"owl.test\" is property file:\n\/\/\n\/\/ https:\/\/en.wikipedia.org\/wiki\/.properties\n\/\/\n\/\/ In order to separate properties, \"owl.test.sep\"(as regular expression) would be used to\n\/\/ recognize a record of property file.\n\/\/\n\/\/ See \"DEFAULT_SEPARATOR\" constant for default separator.\n\/\/\n\/\/ Loading priority\n\/\/\n\/\/ When you execute go test with viable values for both of the environment variables and the flags,\n\/\/ the priority is:\n\/\/\n\/\/ \t1. Load file from environment variable(OWL_TEST_PROPS_FILE)\n\/\/ \t2. Load properties of environment variable(OWL_TEST_PROPS)\n\/\/ \t3. Load file from flag(\"-owl.test.propfile\")\n\/\/ \t4. Load properties from flag(\"-owl.test\")\n\/\/\n\/\/ Pre-defined Properties - Features\n\/\/\n\/\/ There are some pre-defined properties:\n\/\/\n\/\/ \tmysql - MySql connection\n\/\/\n\/\/ \tclient.http.host - HTTP client\n\/\/ \tclient.http.port - HTTP client\n\/\/ \tclient.http.ssl - HTTP client\n\/\/ \tclient.http.resource - HTTP client\n\/\/\n\/\/ \tclient.jsonrpc.host - JSONRPC Client\n\/\/ \tclient.jsonrpc.port - JSONRPC Client\n\/\/\n\/\/ \tit.web.enable - IT to Web\n\/\/\n\/\/ The object of \"*TestFlags\" provides various functions to check\n\/\/ whether or not some configuration for testing are enabled.\n\/\/\n\/\/ For example, \"HasMySql()\" would let you know whether \"mysql=<conn>\" is viable.\n\/\/\n\/\/ Pre-defined Properties - Owl Databases of MySql\n\/\/\n\/\/ Following list shows build-in supporting databases of Owl Database:\n\/\/\n\/\/ \tmysql.owl_portal - MySql connection on OWL-Portal\n\/\/ \tmysql.owl_graph - MySql connection on OWL-Graph\n\/\/ \tmysql.owl_uic - MySql connection on OWL-Uic\n\/\/ \tmysql.owl_links - MySql connection on OWL-Links\n\/\/ \tmysql.owl_grafana - MySql connection on OWL-Grafana\n\/\/ \tmysql.owl_dashboard - MySql connection on OWL-Dashboard\n\/\/ \tmysql.owl_boss - MySql connection on OWL-Boss\n\/\/\n\/\/ You could use \"HasMySqlOfOwlDb(int)\" or \"GetMysqlOfOwlDb(int)\" to retrieve value of properties.\n\/\/\n\/\/ Constraint\n\/\/\n\/\/ The empty string of property value would be considered as non-viable.\npackage flag\n\nimport

Supported extensions:\n .zip\n .tar\n .tar.br\n .tbr\n .tar.gz\n .tgz\n .tar.bz2\n .tbz2\n .tar.xz\n .txz\n .tar.lz4\n .tlz4\n .tar.sz\n .tsz\n .zst\n .tar.zst\n .rar (open only)\n .bz2\n .gz\n .lz4\n .sz\n .xz\n\n (DE)COMPRESSING SINGLE FILES\n Some formats are compression-only, and can be used\n with the compress and decompress commands on a\n single file; they do not bundle multiple files.\n\n To replace a file when compressing, specify the\n source file name for the first argument, and the\n compression format (without leading dot) for the\n second argument. To replace a file when decompressing,\n specify only the source file and no destination.\n\n PASSWORD-PROTECTED RAR FILES\n Export the ARCHIVE_PASSWORD environment variable\n to be able to open password-protected rar archives.\n\n GLOBAL FLAG REFERENCE\n The following global flags may be used before the\n sub-command (some flags are format-specific):\n\n`\n<|endoftext|>"} {"text":"<commit_before>\/****************************************************************************\n * This file is part of Builder.\n *\n * Copyright (C) 2015 Pier Luigi Fiorini\n *\n * Author(s):\n * Pier Luigi Fiorini <pierluigi.fiorini@gmail.com>\n *\n * $BEGIN_LICENSE:AGPL3+$\n *\n * This program is free software: you can redistribute it and\/or modify\n * it under the terms of the GNU Affero General Public License as\n * published by the Free Software Foundation, either version 3 of the\n * License, or (at your option) any later version.\n *\n * This program is distributed in the hope that it will be useful,\n * but WITHOUT ANY WARRANTY; without even the implied warranty of\n * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Tasks\n\/\/ that have been running in kernel mode for a long time in the same syscall\n\/\/ without blocking are considered stuck and are reported.\n\/\/\n\/\/ When a stuck task is detected, the watchdog can take one of the following actions:\n\/\/\t\t1.

The\n\/\/ backup task has three primary phases:\n\/\/ 1. Init: Determines which inputs from the breach transaction will be spent,\n\/\/ and the total amount contained in the inputs.\n\/\/ 2. Bind: Asserts that the revoked state is eligible under a given session's\n\/\/ parameters. Certain states may be ineligible due to fee rates, too little\n\/\/ input amount, etc. Backup of these states can be deferred to a later time\n\/\/ or session with more favorable parameters. If the session is bound\n\/\/ successfully, the final session-dependent values to the justice\n\/\/ transaction are solidified.\n\/\/ 3. Send: Once the task is bound, it will be queued to send to a specific\n\/\/ tower corresponding to the session in which it was bound. The justice\n\/\/ transaction will be assembled by examining the parameters left as a\n\/\/ result of the binding. After the justice transaction is signed, the\n\/\/ necessary components are stripped out and encrypted before being sent to\n\/\/ the tower in a StateUpdate.\ntype backupTask struct {\n\tid wtdb.BackupID\n\tbreachInfo *lnwallet.BreachRetribution\n\n\t\/\/ state-dependent variables\n\n\ttoLocalInput input.Input\n\ttoRemoteInput input.Input\n\ttotalAmt btcutil.Amount\n\tsweepPkScript []byte\n\n\t\/\/ session-dependent variables\n\n\tblobType blob.Type\n\toutputs []*wire.TxOut\n}\n\n\/\/ newBackupTask initializes a new backupTask and populates all state-dependent\n\/\/ variables.\nfunc newBackupTask(chanID *lnwire.ChannelID,\n\tbreachInfo *lnwallet.BreachRetribution,\n\tsweepPkScript []byte, chanType channeldb.ChannelType) *backupTask {\n\n\t\/\/ Parse the non-dust outputs from the breach transaction,\n\t\/\/ simultaneously computing the total amount contained in the inputs\n\t\/\/ present.
