Successive lines are\nrecorded using increasing line numbers, until the next directive. This directive\ntypically appears in machine-generated code, so that compilers and debuggers\nwill show lines in the original input to the generator.\n\n \/\/go:noescape\n\nThe \/\/go:noescape directive specifies that the next declaration in the file, which\nmust be a func without a body (meaning that it has an implementation not written\nin Go) does not allow any of the pointers passed as arguments to escape into the\nheap or into the values returned from the function. This information can be used as\nduring the compiler's escape analysis of Go code calling the function.\n*\/\npackage main\ncmd\/gc: document -pack flag\/\/ Copyright 2009 The Go Authors.

It is therefore not necessary when compiling client C of\npackage P to read the files of P's dependencies, only the compiled output\nof P.\n\nCommand Line\n\nUsage:\n\tgo tool 6g [flags] file...\nThe specified files must be Go source files and all part of the same package.\nSubstitute 6g with 8g or 5g where appropriate.\n\nFlags:\n\t-o file\n\t\toutput file, default file.6 for 6g, etc.\n\t-pack\n\t\twrite a package file rather than an object file\n\t-e\n\t\tnormally the compiler quits after 10 errors; -e prints all errors\n\t-p path\n\t\tassume that path is the eventual import path for this code,\n\t\tand diagnose any attempt to import a package that depends on it.\n\t-D path\n\t\ttreat a relative import as relative to path\n\t-L\n\t\tshow entire file path when printing line numbers in errors\n\t-I dir1 -I dir2\n\t\tadd dir1 and dir2 to the list of paths to check for imported packages\n\t-N\n\t\tdisable optimizations\n\t-S\n\t\twrite assembly language text to standard output (code only)\n\t-S -S\n\t\twrite assembly language text to standard output (code and data)\n\t-u\n\t\tdisallow importing packages not marked as safe\n\t-V\n\t\tprint the compiler version\n\t-race\n\t\tcompile with race detection enabled\n\nThere are also a number of debugging flags; run the command with no arguments\nto get a usage message.\n\nCompiler Directives\n\nThe compiler accepts two compiler directives in the form of \/\/ comments at the\nbeginning of a line. To distinguish them from non-directive comments, the directives\nrequire no space between the slashes and the name of the directive. However, since\nthey are comments, tools unaware of the directive convention or of a particular\ndirective can skip over a directive like any other comment.\n\n \/\/line path\/to\/file:linenumber\n\nThe \/\/line directive specifies that the source line that follows should be recorded\nas having come from the given file path and line number. Successive lines are\nrecorded using increasing line numbers, until the next directive. This directive\ntypically appears in machine-generated code, so that compilers and debuggers\nwill show lines in the original input to the generator.\n\n \/\/go:noescape\n\nThe \/\/go:noescape directive specifies that the next declaration in the file, which\nmust be a func without a body (meaning that it has an implementation not written\nin Go) does not allow any of the pointers passed as arguments to escape into the\nheap or into the values returned from the function. This information can be used as\nduring the compiler's escape analysis of Go code calling the function.\n*\/\npackage main\n<|endoftext|>"} {"text":"package google\n\nimport

When an FD needs to wait,\n\/\/ send the fd on s.cr (for a read) or s.cw (for a write) to pass the\n\/\/ request to the poll server. Then receive on fd.cr\/fd.cw.\n\/\/ When the pollServer finds that i\/o on FD should be possible\n\/\/ again, it will send fd on fd.cr\/fd.cw to wake any waiting processes.\n\/\/ This protocol is implemented as s.WaitRead() and s.WaitWrite().\n\/\/\n\/\/ There is one subtlety: when sending on s.cr\/s.cw, the\n\/\/ poll server is probably in a system call, waiting for an fd\n\/\/ to become ready. It's not looking at the request channels.\n\/\/ To resolve this, the poll server waits not just on the FDs it has\n\/\/ been given but also its own pipe. After sending on the\n\/\/ buffered channel s.cr\/s.cw, WaitRead\/WaitWrite writes a\n\/\/ byte to the pipe, causing the pollServer's poll system call to\n\/\/ return. In response to the pipe being readable, the pollServer\n\/\/ re-polls its request channels.\n\/\/\n\/\/ Note that the ordering is \"send request\" and then \"wake up server\".\n\/\/ If the operations were reversed, there would be a race: the poll\n\/\/ server might wake up and look at the request channel, see that it\n\/\/ was empty, and go back to sleep, all before the requester managed\n\/\/ to send the request. Because the send must complete before the wakeup,\n\/\/ the request channel must be buffered. A buffer of size 1 is sufficient\n\/\/ for any request load. If many processes are trying to submit requests,\n\/\/ one will succeed, the pollServer will read the request, and then the\n\/\/ channel will be empty for the next process's request. A larger buffer\n\/\/ might help batch requests.\n\ntype pollServer struct {\n\tcr, cw chan *netFD;\t\/\/ buffered >= 1\n\tpr, pw *os.File;\n\tpending map[int64] *netFD;\n\tpoll *pollster;\t\/\/ low-level OS hooks\n\tdeadline int64;\t\/\/ next deadline (nsec since 1970)\n}\nfunc (s *pollServer) Run();\n\nfunc newPollServer() (s *pollServer, err os.Error) {\n\ts = new(pollServer);\n\ts.cr = make(chan *netFD, 1);\n\ts.cw = make(chan *netFD, 1);\n\tif s.pr, s.pw, err = os.Pipe();

When an FD needs to wait,\n\/\/ send the fd on s.cr (for a read) or s.cw (for a write) to pass the\n\/\/ request to the poll server. Then receive on fd.cr\/fd.cw.\n\/\/ When the pollServer finds that i\/o on FD should be possible\n\/\/ again, it will send fd on fd.cr\/fd.cw to wake any waiting processes.\n\/\/ This protocol is implemented as s.WaitRead() and s.WaitWrite().\n\/\/\n\/\/ There is one subtlety: when sending on s.cr\/s.cw, the\n\/\/ poll server is probably in a system call, waiting for an fd\n\/\/ to become ready. It's not looking at the request channels.\n\/\/ To resolve this, the poll server waits not just on the FDs it has\n\/\/ been given but also its own pipe. After sending on the\n\/\/ buffered channel s.cr\/s.cw, WaitRead\/WaitWrite writes a\n\/\/ byte to the pipe, causing the pollServer's poll system call to\n\/\/ return. In response to the pipe being readable, the pollServer\n\/\/ re-polls its request channels.\n\/\/\n\/\/ Note that the ordering is \"send request\" and then \"wake up server\".\n\/\/ If the operations were reversed, there would be a race: the poll\n\/\/ server might wake up and look at the request channel, see that it\n\/\/ was empty, and go back to sleep, all before the requester managed\n\/\/ to send the request. Because the send must complete before the wakeup,\n\/\/ the request channel must be buffered. A buffer of size 1 is sufficient\n\/\/ for any request load. If many processes are trying to submit requests,\n\/\/ one will succeed, the pollServer will read the request, and then the\n\/\/ channel will be empty for the next process's request. A larger buffer\n\/\/ might help batch requests.\n\ntype pollServer struct {\n\tcr, cw chan *netFD;\t\/\/ buffered >= 1\n\tpr, pw *os.File;\n\tpending map[int64] *netFD;\n\tpoll *pollster;\t\/\/ low-level OS hooks\n\tdeadline int64;\t\/\/ next deadline (nsec since 1970)\n}\nfunc (s *pollServer) Run();\n\nfunc newPollServer() (s *pollServer, err *os.Error) {\n\ts = new(pollServer);\n\ts.cr = make(chan *netFD, 1);\n\ts.cw = make(chan *netFD, 1);\n\tif s.pr, s.pw, err = os.Pipe();

When an FD needs to wait,\n\/\/ send the fd on s.cr (for a read) or s.cw (for a write) to pass the\n\/\/ request to the poll server. Then receive on fd.cr\/fd.cw.\n\/\/ When the pollServer finds that i\/o on FD should be possible\n\/\/ again, it will send fd on fd.cr\/fd.cw to wake any waiting processes.\n\/\/ This protocol is implemented as s.WaitRead() and s.WaitWrite().\n\/\/\n\/\/ There is one subtlety: when sending on s.cr\/s.cw, the\n\/\/ poll server is probably in a system call, waiting for an fd\n\/\/ to become ready. It's not looking at the request channels.\n\/\/ To resolve this, the poll server waits not just on the FDs it has\n\/\/ been given but also its own pipe. After sending on the\n\/\/ buffered channel s.cr\/s.cw, WaitRead\/WaitWrite writes a\n\/\/ byte to the pipe, causing the pollServer's poll system call to\n\/\/ return. In response to the pipe being readable, the pollServer\n\/\/ re-polls its request channels.\n\/\/\n\/\/ Note that the ordering is \"send request\" and then \"wake up server\".\n\/\/ If the operations were reversed, there would be a race: the poll\n\/\/ server might wake up and look at the request channel, see that it\n\/\/ was empty, and go back to sleep, all before the requester managed\n\/\/ to send the request. Because the send must complete before the wakeup,\n\/\/ the request channel must be buffered. A buffer of size 1 is sufficient\n\/\/ for any request load. If many processes are trying to submit requests,\n\/\/ one will succeed, the pollServer will read the request, and then the\n\/\/ channel will be empty for the next process's request. A larger buffer\n\/\/ might help batch requests.\n\ntype pollServer struct {\n\tcr, cw chan *netFD;\t\/\/ buffered >= 1\n\tpr, pw *os.File;\n\tpending map[int64] *netFD;\n\tpoll *pollster;\t\/\/ low-level OS hooks\n\tdeadline int64;\t\/\/ next deadline (nsec since 1970)\n}\nfunc (s *pollServer) Run();\n\nfunc newPollServer() (s *pollServer, err *os.Error) {\n\ts = new(pollServer);\n\ts.cr = make(chan *netFD, 1);\n\ts.cw = make(chan *netFD, 1);\n\tif s.pr, s.pw, err = os.Pipe();

In the URL you received from\n\t\tSnowflake, your account name is the first segment in the domain (e.g.\n\t\tabc123 in https:\/\/abc123.snowflakecomputing.com). This parameter is\n\t\toptional if your account is specified after the @ character. If you are not on us-west-2 region\n or AWS deployment, append the region and platform to the end, e.g., <account>.<region>,\n <account>.<region>.<platform>.\n\n\t* region <string>: DEPRECATED. Append a region or any sub domains before snowflakecomputing.com to the\n end of account parameter after a dot, e.g., account=<account>.<region>.\n\n\t* database: Specifies the database to use by default in the client session\n\t\t(can be changed after login).\n\n\t* schema: Specifies the database schema to use by default in the client\n\t\tsession (can be changed after login).\n\n\t* warehouse: Specifies the virtual warehouse to use by default for queries,\n\t\tloading, etc. in the client session (can be changed after login).\n\n\t* role: Specifies the role to use by default for accessing Snowflake\n\t\tobjects in the client session (can be changed after login).\n\n\t* passcode: Specifies the passcode provided by Duo when using MFA for login.\n\n\t* passcodeInPassword: false by default. Set to true if the MFA passcode is\n\t\tembedded in the login password. Appends the MFA passcode to the end of the\n\t\tpassword.\n\n\t* loginTimeout: Specifies the timeout, in seconds, for login. The default\n\t\tis 60 seconds. The login request gives up after the timeout length if the\n\t\tHTTP response is success.\n\n\t* authenticator: Specifies the authenticator to use for authenticating user credentials:\n\t\t- To use the internal Snowflake authenticator, specify snowflake (Default).\n\t\t- To authenticate through Okta, specify https:\/\/<okta_account_name>.okta.com (URL prefix for Okta).\n\t\t- To authenticate using your IDP via a browser, specify externalbrowser.\n\t\t- To authenticate via OAuth, specify oauth and provide an OAuth Access Token (see the token parameter below).\n\n\t* application: Identifies your application to Snowflake Support.\n\n\t* insecureMode false by default. Set to true to bypass the Online\n\t\tCertificate Status Protocol (OCSP) certificate revocation check.\n\t\tIMPORTANT: Change the default value for testing or emergency situations only.\n\n\t* token: a token that can be used to authenticate. Should be used in conjunction with the \"oauth\" authenticator.\n\n\t* client_session_keep_alive: Set to true have a heartbeat in the background every hour to keep the connection alive\n\t\tsuch that the connection session will never expire. Care should be taken in using this option as it opens up\n\t\tthe access forever as long as the process is alive.\n\n\nAll other parameters are taken as session parameters. For example, TIMESTAMP_OUTPUT_FORMAT session parameter can be\nset by adding:\n\n\t...&TIMESTAMP_OUTPUT_FORMAT=MM-DD-YYYY...\n\nProxy\n\nThe Go Snowflake Driver honors the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY for the forward proxy setting.\n\nLogging\n\nBy default, the driver's builtin logger is NOP; no output is generated. This is\nintentional for those applications that use the same set of logger parameters\nnot to conflict with glog, which is incorporated in the driver logging\nframework.\n\nIn order to enable debug logging for the driver, add a build tag sfdebug to the\ngo tool command lines, for example:\n\n\tgo build -tags=sfdebug\n\nFor tests, run the test command with the tag along with glog parameters. For\nexample, the following command will generate all acitivty logs in the standard\nerror.\n\n\tgo test -tags=sfdebug -v . -vmodule=*=2 -stderrthreshold=INFO\n\nLikewise, if you build your application with the tag, you may specify the same\nset of glog parameters.\n\n\tyour_go_program -vmodule=*=2 -stderrthreshold=INFO\n\nTo get the logs for a specific module, use the -vmodule option. For example, to\nretrieve the driver.go and connection.go module logs:\n\n\tyour_go_program -vmodule=driver=2,connection=2 -stderrthreshold=INFO\n\nNote: If your request retrieves no logs, call db.Close() or glog.flush() to flush the glog buffer.\n\nNote: The logger may be changed in the future for better logging. Currently if\nthe applications use the same parameters as glog, you cannot collect both\napplication and driver logs at the same time.\n\nCanceling Query by CtrlC\n\nFrom 0.5.0, a signal handling responsibility has moved to the applications. If you want to cancel a\nquery\/command by Ctrl+C, add a os.Interrupt trap in context to execute methods that can take the context parameter,\ne.g., QueryContext, ExecContext.\n\n\t\/\/ handle interrupt signal\n\tctx, cancel := context.WithCancel(context.Background())\n\tc := make(chan os.Signal, 1)\n\tsignal.Notify(c, os.Interrupt)\n\tdefer func() {\n\t\tsignal.Stop(c)\n\t}()\n\tgo func() {\n\t\t<-c\n\t\tlog.Println(\"Caught signal, canceling...\")\n\t\tcancel()\n\t}()\n\t... (connection)\n\t\/\/ execute a query\n\trows, err := db.QueryContext(ctx, query)\n\t... (Ctrl+C to cancel the query)\n\nSee cmd\/selectmany.go for the full example.\n\nSupported Data Types\n\nQueries return SQL column type information in the ColumnType type. The\nDatabaseTypeName method returns the following strings representing Snowflake\ndata types:\n\n\tString Representation\tSnowflake Data Type\n\tFIXED\t NUMBER\/INT\n\tREAL\t REAL\n\tTEXT\t VARCHAR\/STRING\n\tDATE\t DATE\n\tTIME\t TIME\n\tTIMESTAMP_LTZ\t TIMESTAMP_LTZ\n\tTIMESTAMP_NTZ\t TIMESTAMP_NTZ\n\tTIMESTAMP_TZ\t TIMESTAMP_TZ\n\tVARIANT\t VARIANT\n\tOBJECT\t OBJECT\n\tARRAY\t ARRAY\n\tBINARY\t BINARY\n\tBOOLEAN\t BOOLEAN\n\nBinding Time Type\n\nGo's database\/sql package limits Go's data types to the following for binding and fetching:\n\n\tint64\n\tfloat64\n\tbool\n\t[]byte\n\tstring\n\ttime.Time\n\nFetching data isn't an issue since the database data type is provided along\nwith the data so the Go Snowflake Driver can translate Snowflake data types to\nGo native data types.\n\nWhen the client binds data to send to the server, however, the driver cannot\ndetermine the date\/timestamp data types to associate with binding parameters.\nFor example:\n\n\tdbt.mustExec(\"CREATE OR REPLACE TABLE tztest (id int, ntz, timestamp_ntz, ltz timestamp_ltz)\")\n\t\/\/ ...\n\tstmt, err :=dbt.db.Prepare(\"INSERT INTO tztest(id,ntz,ltz) VALUES(1, ?, ?)\")\n\t\/\/ ...\n\ttmValue time.Now()\n\t\/\/ ... Is tmValue a TIMESTAMP_NTZ or TIMESTAMP_LTZ?\n\t_, err = stmt.Exec(tmValue, tmValue)\n\nTo resolve this issue, a binding parameter flag is introduced that associates\nany subsequent time.Time type to the DATE, TIME, TIMESTAMP_LTZ, TIMESTAMP_NTZ\nor BINARY data type. The above example could be rewritten as follows:\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tdbt.mustExec(\"CREATE OR REPLACE TABLE tztest (id int, ntz, timestamp_ntz, ltz timestamp_ltz)\")\n\t\/\/ ...\n\tstmt, err :=dbt.db.Prepare(\"INSERT INTO tztest(id,ntz,ltz) VALUES(1, ?, ?)\")\n\t\/\/ ...\n\ttmValue time.Now()\n\t\/\/ ...\n\t_, err = stmt.Exec(sf.DataTypeTimestampNtz, tmValue, sf.DataTypeTimestampLtz, tmValue)\n\nTimestamps with Time Zones\n\nThe driver fetches TIMESTAMP_TZ (timestamp with time zone) data using the\noffset-based Location types, which represent a collection of time offsets in\nuse in a geographical area, such as CET (Central European Time) or UTC\n(Coordinated Universal Time). The offset-based Location data is generated and\ncached when a Go Snowflake Driver application starts, and if the given offset\nis not in the cache, it is generated dynamically.\n\nCurrently, Snowflake doesn't support the name-based Location types, e.g.,\nAmerica\/Los_Angeles.\n\nFor more information about Location types, see the Go documentation for https:\/\/golang.org\/pkg\/time\/#Location.\n\nBinary Data\n\nInternally, this feature leverages the []byte data type. As a result, BINARY\ndata cannot be bound without the binding parameter flag. In the following\nexample, sf is an alias for the gosnowflake package:\n\n\tvar b = []byte{0x01, 0x02, 0x03}\n\t_, err = stmt.Exec(sf.DataTypeBinary, b)\n\nMaximum number of Result Set Chunk Downloader\n\nThe driver directly downloads a result set from the cloud storage if the size is large. It is\nrequired to shift workloads from the Snowflake database to the clients for scale. The download takes place by goroutine\nnamed \"Chunk Downloader\" asynchronously so that the driver can fetch the next result set while the application can\nconsume the current result set.\n\nThe application may change the number of result set chunk downloader if required. Note this doesn't help reduce\nmemory footprint by itself. Consider Custom JSON Decoder.\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tsf.MaxChunkDownloadWorkers = 2\n\n\nExperimental: Custom JSON Decoder for parsing Result Set\n\nThe application may have the driver use a custom JSON decoder that incrementally parses the result set as follows.\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tsf.CustomJSONDecoderEnabled = true\n\t...\n\nThis option will reduce the memory footprint to half or even quarter, but it can significantly degrade the\nperformance depending on the environment. The test cases running on Travis Ubuntu box show five times less memory\nfootprint while four times slower. Be cautious when using the option.\n\n(Private Preview) JWT authentication\n\n** Not recommended for production use until GA\n\nNow JWT token is supported when compiling with a golang version of 1.10 or higher. Binary compiled with lower version\nof golang would return an error at runtime when users try to use JWT authentication feature.\n\nTo enable this feature, one can construct DSN with fields \"authenticator=SNOWFLAKE_JWT&privateKey=<your_private_key>\",\nor using Config structure specifying:\n\n\tconfig := &Config{\n\t\t...\n\t\tAuthenticator: \"SNOWFLAKE_JWT\"\n\t\tPrivateKey: \"<your_private_key_struct in *rsa.PrivateKey type>\"\n\t}\n\nThe <your_private_key> should be a base64 URL encoded PKCS8 rsa private key string. One way to encode a byte slice to URL\nbase 64 URL format is through base64.URLEncoding.EncodeToString() function.\n\nOn the server side, one can alter the public key with the SQL command:\n\n\tALTER USER <your_user_name> SET RSA_PUBLIC_KEY='<your_public_key>';\n\nThe <your_public_key> should be a base64 Standard encoded PKI public key string. One way to encode a byte slice to base\n64 Standard format is through base64.StdEncoding.EncodeToString() function.\n\nTo generate the valid key pair, one can do the following command on the shell script:\n\n\t# generate 2048-bit pkcs8 encoded RSA private key\n\topenssl genpkey -algorithm RSA \\\n \t-pkeyopt rsa_keygen_bits:2048 \\\n \t-pkeyopt rsa_keygen_pubexp:65537 | \\\n \t\topenssl pkcs8 -topk8 -nocrypt -outform der > rsa-2048-private-key.p8\n\n\t# extravt 2048-bit PKI encoded RSA public key from the private key\n\topenssl pkey -pubout -inform der -outform der \\\n \t-in rsa-2048-private-key.p8 \\\n \t-out rsa-2048-public-key.spki\n\nLimitations\n\nGET and PUT operations are unsupported.\n*\/\npackage gosnowflake\n<commit_msg>Improved the doc for region parameter description<commit_after>\/*\nPackage gosnowflake is a pure Go Snowflake driver for the database\/sql package.\n\nClients can use the database\/sql package directly.

For details, see the description of the account parameter.\n\n\t* database: Specifies the database to use by default in the client session\n\t\t(can be changed after login).\n\n\t* schema: Specifies the database schema to use by default in the client\n\t\tsession (can be changed after login).\n\n\t* warehouse: Specifies the virtual warehouse to use by default for queries,\n\t\tloading, etc. in the client session (can be changed after login).\n\n\t* role: Specifies the role to use by default for accessing Snowflake\n\t\tobjects in the client session (can be changed after login).\n\n\t* passcode: Specifies the passcode provided by Duo when using MFA for login.\n\n\t* passcodeInPassword: false by default. Set to true if the MFA passcode is\n\t\tembedded in the login password. Appends the MFA passcode to the end of the\n\t\tpassword.\n\n\t* loginTimeout: Specifies the timeout, in seconds, for login. The default\n\t\tis 60 seconds. The login request gives up after the timeout length if the\n\t\tHTTP response is success.\n\n\t* authenticator: Specifies the authenticator to use for authenticating user credentials:\n\t\t- To use the internal Snowflake authenticator, specify snowflake (Default).\n\t\t- To authenticate through Okta, specify https:\/\/<okta_account_name>.okta.com (URL prefix for Okta).\n\t\t- To authenticate using your IDP via a browser, specify externalbrowser.\n\t\t- To authenticate via OAuth, specify oauth and provide an OAuth Access Token (see the token parameter below).\n\n\t* application: Identifies your application to Snowflake Support.\n\n\t* insecureMode false by default. Set to true to bypass the Online\n\t\tCertificate Status Protocol (OCSP) certificate revocation check.\n\t\tIMPORTANT: Change the default value for testing or emergency situations only.\n\n\t* token: a token that can be used to authenticate. Should be used in conjunction with the \"oauth\" authenticator.\n\n\t* client_session_keep_alive: Set to true have a heartbeat in the background every hour to keep the connection alive\n\t\tsuch that the connection session will never expire. Care should be taken in using this option as it opens up\n\t\tthe access forever as long as the process is alive.\n\n\nAll other parameters are taken as session parameters. For example, TIMESTAMP_OUTPUT_FORMAT session parameter can be\nset by adding:\n\n\t...&TIMESTAMP_OUTPUT_FORMAT=MM-DD-YYYY...\n\nProxy\n\nThe Go Snowflake Driver honors the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY for the forward proxy setting.\n\nLogging\n\nBy default, the driver's builtin logger is NOP; no output is generated. This is\nintentional for those applications that use the same set of logger parameters\nnot to conflict with glog, which is incorporated in the driver logging\nframework.\n\nIn order to enable debug logging for the driver, add a build tag sfdebug to the\ngo tool command lines, for example:\n\n\tgo build -tags=sfdebug\n\nFor tests, run the test command with the tag along with glog parameters. For\nexample, the following command will generate all acitivty logs in the standard\nerror.\n\n\tgo test -tags=sfdebug -v . -vmodule=*=2 -stderrthreshold=INFO\n\nLikewise, if you build your application with the tag, you may specify the same\nset of glog parameters.\n\n\tyour_go_program -vmodule=*=2 -stderrthreshold=INFO\n\nTo get the logs for a specific module, use the -vmodule option. For example, to\nretrieve the driver.go and connection.go module logs:\n\n\tyour_go_program -vmodule=driver=2,connection=2 -stderrthreshold=INFO\n\nNote: If your request retrieves no logs, call db.Close() or glog.flush() to flush the glog buffer.\n\nNote: The logger may be changed in the future for better logging. Currently if\nthe applications use the same parameters as glog, you cannot collect both\napplication and driver logs at the same time.\n\nCanceling Query by CtrlC\n\nFrom 0.5.0, a signal handling responsibility has moved to the applications. If you want to cancel a\nquery\/command by Ctrl+C, add a os.Interrupt trap in context to execute methods that can take the context parameter,\ne.g., QueryContext, ExecContext.\n\n\t\/\/ handle interrupt signal\n\tctx, cancel := context.WithCancel(context.Background())\n\tc := make(chan os.Signal, 1)\n\tsignal.Notify(c, os.Interrupt)\n\tdefer func() {\n\t\tsignal.Stop(c)\n\t}()\n\tgo func() {\n\t\t<-c\n\t\tlog.Println(\"Caught signal, canceling...\")\n\t\tcancel()\n\t}()\n\t... (connection)\n\t\/\/ execute a query\n\trows, err := db.QueryContext(ctx, query)\n\t... (Ctrl+C to cancel the query)\n\nSee cmd\/selectmany.go for the full example.\n\nSupported Data Types\n\nQueries return SQL column type information in the ColumnType type. The\nDatabaseTypeName method returns the following strings representing Snowflake\ndata types:\n\n\tString Representation\tSnowflake Data Type\n\tFIXED\t NUMBER\/INT\n\tREAL\t REAL\n\tTEXT\t VARCHAR\/STRING\n\tDATE\t DATE\n\tTIME\t TIME\n\tTIMESTAMP_LTZ\t TIMESTAMP_LTZ\n\tTIMESTAMP_NTZ\t TIMESTAMP_NTZ\n\tTIMESTAMP_TZ\t TIMESTAMP_TZ\n\tVARIANT\t VARIANT\n\tOBJECT\t OBJECT\n\tARRAY\t ARRAY\n\tBINARY\t BINARY\n\tBOOLEAN\t BOOLEAN\n\nBinding Time Type\n\nGo's database\/sql package limits Go's data types to the following for binding and fetching:\n\n\tint64\n\tfloat64\n\tbool\n\t[]byte\n\tstring\n\ttime.Time\n\nFetching data isn't an issue since the database data type is provided along\nwith the data so the Go Snowflake Driver can translate Snowflake data types to\nGo native data types.\n\nWhen the client binds data to send to the server, however, the driver cannot\ndetermine the date\/timestamp data types to associate with binding parameters.\nFor example:\n\n\tdbt.mustExec(\"CREATE OR REPLACE TABLE tztest (id int, ntz, timestamp_ntz, ltz timestamp_ltz)\")\n\t\/\/ ...\n\tstmt, err :=dbt.db.Prepare(\"INSERT INTO tztest(id,ntz,ltz) VALUES(1, ?, ?)\")\n\t\/\/ ...\n\ttmValue time.Now()\n\t\/\/ ... Is tmValue a TIMESTAMP_NTZ or TIMESTAMP_LTZ?\n\t_, err = stmt.Exec(tmValue, tmValue)\n\nTo resolve this issue, a binding parameter flag is introduced that associates\nany subsequent time.Time type to the DATE, TIME, TIMESTAMP_LTZ, TIMESTAMP_NTZ\nor BINARY data type. The above example could be rewritten as follows:\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tdbt.mustExec(\"CREATE OR REPLACE TABLE tztest (id int, ntz, timestamp_ntz, ltz timestamp_ltz)\")\n\t\/\/ ...\n\tstmt, err :=dbt.db.Prepare(\"INSERT INTO tztest(id,ntz,ltz) VALUES(1, ?, ?)\")\n\t\/\/ ...\n\ttmValue time.Now()\n\t\/\/ ...\n\t_, err = stmt.Exec(sf.DataTypeTimestampNtz, tmValue, sf.DataTypeTimestampLtz, tmValue)\n\nTimestamps with Time Zones\n\nThe driver fetches TIMESTAMP_TZ (timestamp with time zone) data using the\noffset-based Location types, which represent a collection of time offsets in\nuse in a geographical area, such as CET (Central European Time) or UTC\n(Coordinated Universal Time). The offset-based Location data is generated and\ncached when a Go Snowflake Driver application starts, and if the given offset\nis not in the cache, it is generated dynamically.\n\nCurrently, Snowflake doesn't support the name-based Location types, e.g.,\nAmerica\/Los_Angeles.\n\nFor more information about Location types, see the Go documentation for https:\/\/golang.org\/pkg\/time\/#Location.\n\nBinary Data\n\nInternally, this feature leverages the []byte data type. As a result, BINARY\ndata cannot be bound without the binding parameter flag. In the following\nexample, sf is an alias for the gosnowflake package:\n\n\tvar b = []byte{0x01, 0x02, 0x03}\n\t_, err = stmt.Exec(sf.DataTypeBinary, b)\n\nMaximum number of Result Set Chunk Downloader\n\nThe driver directly downloads a result set from the cloud storage if the size is large. It is\nrequired to shift workloads from the Snowflake database to the clients for scale. The download takes place by goroutine\nnamed \"Chunk Downloader\" asynchronously so that the driver can fetch the next result set while the application can\nconsume the current result set.\n\nThe application may change the number of result set chunk downloader if required. Note this doesn't help reduce\nmemory footprint by itself. Consider Custom JSON Decoder.\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tsf.MaxChunkDownloadWorkers = 2\n\n\nExperimental: Custom JSON Decoder for parsing Result Set\n\nThe application may have the driver use a custom JSON decoder that incrementally parses the result set as follows.\n\n\timport (\n\t\tsf \"github.com\/snowflakedb\/gosnowflake\"\n\t)\n\tsf.CustomJSONDecoderEnabled = true\n\t...\n\nThis option will reduce the memory footprint to half or even quarter, but it can significantly degrade the\nperformance depending on the environment. The test cases running on Travis Ubuntu box show five times less memory\nfootprint while four times slower. Be cautious when using the option.\n\n(Private Preview) JWT authentication\n\n** Not recommended for production use until GA\n\nNow JWT token is supported when compiling with a golang version of 1.10 or higher. Binary compiled with lower version\nof golang would return an error at runtime when users try to use JWT authentication feature.\n\nTo enable this feature, one can construct DSN with fields \"authenticator=SNOWFLAKE_JWT&privateKey=<your_private_key>\",\nor using Config structure specifying:\n\n\tconfig := &Config{\n\t\t...\n\t\tAuthenticator: \"SNOWFLAKE_JWT\"\n\t\tPrivateKey: \"<your_private_key_struct in *rsa.PrivateKey type>\"\n\t}\n\nThe <your_private_key> should be a base64 URL encoded PKCS8 rsa private key string. One way to encode a byte slice to URL\nbase 64 URL format is through base64.URLEncoding.EncodeToString() function.\n\nOn the server side, one can alter the public key with the SQL command:\n\n\tALTER USER <your_user_name> SET RSA_PUBLIC_KEY='<your_public_key>';\n\nThe <your_public_key> should be a base64 Standard encoded PKI public key string. One way to encode a byte slice to base\n64 Standard format is through base64.StdEncoding.EncodeToString() function.\n\nTo generate the valid key pair, one can do the following command on the shell script:\n\n\t# generate 2048-bit pkcs8 encoded RSA private key\n\topenssl genpkey -algorithm RSA \\\n \t-pkeyopt rsa_keygen_bits:2048 \\\n \t-pkeyopt rsa_keygen_pubexp:65537 | \\\n \t\topenssl pkcs8 -topk8 -nocrypt -outform der > rsa-2048-private-key.p8\n\n\t# extravt 2048-bit PKI encoded RSA public key from the private key\n\topenssl pkey -pubout -inform der -outform der \\\n \t-in rsa-2048-private-key.p8 \\\n \t-out rsa-2048-public-key.spki\n\nLimitations\n\nGET and PUT operations are unsupported.\n*\/\npackage gosnowflake\n<|endoftext|>"} {"text":"<commit_before>\/*Package recovr is a HTTP middleware that catches any panics and serves a proper error response.\n\npackage main\n\nimport (\n\t\"log\"\n\t\"net\/http\"\n\n\t\"github.com\/dre1080\/recovr\"\n)\n\nvar myPanicHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n\tpanic(\"you should not have a handler that just panics ;)\")\n})\n\nfunc main() {\n\trecovery := recovr.New()\n\tapp := recovery(myPanicHandler)\n\thttp.ListenAndServe(\"0.0.0.0:3000\", app)\n}\n*\/\npackage recovr\n<commit_msg>release: v1.0.2<commit_after>\/\/ Package recovr is a HTTP middleware that catches any panics and serves a proper error response.\n\/\/\n\/\/ \tpackage main\n\/\/\n\/\/ \timport (\n\/\/ \t\t\"log\"\n\/\/ \t\t\"net\/http\"\n\/\/ \t\t\"github.com\/dre1080\/recovr\"\n\/\/ \t)\n\/\/\n\/\/ \tvar myPanicHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n\/\/ \t\tpanic(\"you should not have a handler that just panics ;)\")\n\/\/ \t})\n\/\/\n\/\/ \tfunc main() {\n\/\/ \t\trecovery := recovr.New()\n\/\/ \t\tapp := recovery(myPanicHandler)\n\/\/ \t\thttp.ListenAndServe(\"0.0.0.0:3000\", app)\n\/\/ \t}\npackage recovr\n<|endoftext|>"} {"text":"<commit_before>\/\/ Use of this source code is governed by a MIT\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage looli is a minimalist web framework for go\n\nrouter usage\n router := looli.Default()\n\n v1 := router.Prefix(\"\/v1\")\n v1.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world version1\\n\")\n })\n\n v2 := router.Prefix(\"\/v2\")\n v2.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world version2\\n\")\n })\n\n router.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world!\\n\")\n })\n*\/\npackage looli\n<commit_msg>fix: update doc<commit_after>\/\/ Use of this source code is governed by a MIT\n\/\/ license that can be found in the LICENSE file.\n\n\/*\nPackage looli is a minimalist web framework for go\n\n router := looli.Default()\n\n v1 := router.Prefix(\"\/v1\")\n v1.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world version1\\n\")\n })\n\n v2 := router.Prefix(\"\/v2\")\n v2.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world version2\\n\")\n })\n\n router.Get(\"\/a\", func(c *looli.Context) {\n c.Status(200)\n c.String(\"hello world!\\n\")\n })\n*\/\npackage looli\n<|endoftext|>"} {"text":"<commit_before>\/\/ Package glue provides a simple interface to writing HTTP services in Go\n\/\/\n\/\/ It aims to be small and as simple as possible while exposing a pleasant API.\n\/\/ \n\/\/ Glue uses reflection and dependency injection to provide a flexible API for your\n\/\/ HTTP endpoints.

This format makes it easy to set all vars by\nrunning the following bash command (or similar for other shells):\n eval $(v23 env)\n\nIf arguments are given, prints only the value of each named variable, each on a\nseparate line in the same order as the arguments.\n\nUsage:\n v23 env [flags] [name ...]\n\n[name ...] is an optional list of variable names.\n\nThe v23 env flags are:\n -platform=\n Target platform.\n\nV23 Go\n\nWrapper around the 'go' tool that can be used for compilation of vanadium Go\nsources.

This functionality is needed to avoid accidental use of\nstale object files that correspond to packages that no longer exist in the\nsource tree.\n\nUsage:\n v23 goext distclean\n\nV23 Profile\n\nTo facilitate development across different platforms, vanadium defines\nplatform-independent profiles that map different platforms to a set of libraries\nand tools that can be used for a factor of vanadium development.\n\nUsage:\n v23 profile <command>\n\nThe v23 profile commands are:\n list List known vanadium profiles\n setup Set up the given vanadium profiles\n\nV23 Profile List\n\nList known vanadium profiles.\n\nUsage:\n v23 profile list\n\nV23 Profile Setup\n\nSet up the given vanadium profiles.\n\nUsage:\n v23 profile setup <profiles>\n\n<profiles> is a list of profiles to set up.\n\nV23 Project\n\nManage the vanadium projects.\n\nUsage:\n v23 project [flags] <command>\n\nThe v23 project commands are:\n list List existing vanadium projects and branches\n shell-prompt Print a succinct status of projects, suitable for shell prompts\n poll Poll existing vanadium projects\n\nThe v23 project flags are:\n -manifest=default\n Name of the project manifest.\n\nV23 Project List\n\nInspect the local filesystem and list the existing projects and branches.\n\nUsage:\n v23 project list [flags]\n\nThe v23 project list flags are:\n -branches=false\n Show project branches.\n -nopristine=false\n If true, omit pristine projects, i.e. projects with a clean master branch and\n no other branches.\n\nV23 Project Shell-Prompt\n\nReports current branches of vanadium projects (repositories) as well as an\nindication of each project's status:\n * indicates that a repository contains uncommitted changes\n % indicates that a repository contains untracked files\n\nUsage:\n v23 project shell-prompt [flags]\n\nThe v23 project shell-prompt flags are:\n -check_dirty=true\n If false, don't check for uncommitted changes or untracked files. Setting\n this option to false is dangerous: dirty master branches will not appear in\n the output.\n -show_current_repo_name=false\n Show the name of the current repo.\n\nV23 Project Poll\n\nPoll vanadium projects that can affect the outcome of the given tests and report\nwhether any new changes in these projects exist. If no tests are specified, all\nprojects are polled by default.\n\nUsage:\n v23 project poll <test ...>\n\n<test ...> is a list of tests that determine what projects to poll.\n\nV23 Run\n\nRun an executable using the vanadium environment.\n\nUsage:\n v23 run <executable> [arg ...]\n\n<executable> [arg ...] is the executable to run and any arguments to pass\nverbatim to the executable.\n\nV23 Snapshot\n\nThe \"v23 snapshot\" command can be used to manage snapshots of the vanadium\nproject. In particular, it can be used to create new snapshots and to list\nexisting snapshots.\n\nThe command-line flag \"-remote\" determines whether the command pertains to\n\"local\" snapshots that are only stored locally or \"remote\" snapshots the are\nrevisioned in the manifest repository.\n\nUsage:\n v23 snapshot [flags] <command>\n\nThe v23 snapshot commands are:\n create Create a new snapshot of the vanadium project\n list List existing snapshots of vanadium projects\n\nThe v23 snapshot flags are:\n -remote=false\n Manage remote snapshots.\n\nV23 Snapshot Create\n\nThe \"v23 snapshot create <label>\" command first checks whether the vanadium\nproject configuration associates the given label with any tests. If so, the\ncommand checks that all of these tests pass.\n\nNext, the command captures the current state of the vanadium project as a\nmanifest and, depending on the value of the -remote flag, the command either\nstores the manifest in the local $VANADIUM_ROOT\/.snapshots directory, or in the\nmanifest repository, pushing the change to the remote repository and thus making\nit available globally.\n\nInternally, snapshots are organized as follows:\n\n <snapshot-dir>\/\n labels\/\n <label1>\/\n <label1-snapshot1>\n <label1-snapshot2>\n ...\n <label2>\/\n <label2-snapshot1>\n <label2-snapshot2>\n ...\n <label3>\/\n ...\n <label1> # a symlink to the latest <label1-snapshot*>\n <label2> # a symlink to the latest <label2-snapshot*>\n ...\n\nNOTE: Unlike the v23 tool commands, the above internal organization is not an\nAPI. It is an implementation and can change without notice.\n\nUsage:\n v23 snapshot create <label>\n\n<label> is the snapshot label.\n\nV23 Snapshot List\n\nThe \"snapshot list\" command lists existing snapshots of the labels specified as\ncommand-line arguments. If no arguments are provided, the command lists\nsnapshots for all known labels.\n\nUsage:\n v23 snapshot list <label ...>\n\n<label ...> is a list of snapshot labels.\n\nV23 Test\n\nManage vanadium tests.\n\nUsage:\n v23 test <command>\n\nThe v23 test commands are:\n project Run tests for a vanadium project\n run Run vanadium tests\n list List vanadium tests\n\nV23 Test Project\n\nRuns tests for a vanadium project that is by the remote URL specified as the\ncommand-line argument. Projects hosted on googlesource.com, can be specified\nusing the basename of the URL (e.g. \"vanadium.go.core\" implies\n\"https:\/\/vanadium.googlesource.com\/vanadium.go.core\").\n\nUsage:\n v23 test project <project>\n\n<project> identifies the project for which to run tests.\n\nV23 Test Run\n\nRun vanadium tests.\n\nUsage:\n v23 test run <name ...>\n\n<name ...> is a list names identifying the tests to run.\n\nV23 Test List\n\nList vanadium tests.\n\nUsage:\n v23 test list\n\nV23 Update\n\nUpdates all vanadium projects, builds the latest version of vanadium tools, and\ninstalls the resulting binaries into $VANADIUM_ROOT\/bin. The sequence in which\nthe individual updates happen guarantees that we end up with a consistent set of\ntools and source code.\n\nThe set of project and tools to update is describe by a manifest. Vanadium\nmanifests are revisioned and stored in a \"manifest\" repository, that is\navailable locally in $VANADIUM_ROOT\/.manifest. The manifest uses the following\nXML schema:\n\n <manifest>\n <imports>\n <import name=\"default\"\/>\n ...\n <\/imports>\n <projects>\n <project name=\"https:\/\/vanadium.googlesource.com\/vanadium.go.core\"\n path=\"release\/go\/src\/v.io\/veyron\"\n protocol=\"git\"\n revision=\"HEAD\"\/>\n ...\n <\/projects>\n <tools>\n <tool name=\"v23\" package=\"v.io\/tools\/v23\"\/>\n ...\n <\/tools>\n <\/manifest>\n\nThe <import> element can be used to share settings across multiple manifests.\nImport names are interpreted relative to the $VANADIUM_ROOT\/.manifest\/v1\ndirectory. Import cycles are not allowed and if a project or a tool is specified\nmultiple times, the last specification takes effect. In particular, the elements\n<project name=\"foo\" exclude=\"true\"\/> and <tool name=\"bar\" exclude=\"true\"\/> can\nbe used to exclude previously included projects and tools.\n\nThe tool identifies which manifest to use using the following algorithm. If the\n$VANADIUM_ROOT\/.local_manifest file exists, then it is used. Otherwise, the\n$VANADIUM_ROOT\/.manifest\/v1\/<manifest>.xml file is used, which <manifest> is the\nvalue of the -manifest command-line flag, which defaults to \"default\".\n\nNOTE: Unlike the v23 tool commands, the above manifest file format is not an\nAPI. It is an implementation and can change without notice.\n\nUsage:\n v23 update [flags]\n\nThe v23 update flags are:\n -gc=false\n Garbage collect obsolete repositories.\n -manifest=default\n Name of the project manifest.\n\nV23 Version\n\nPrint version of the v23 tool.\n\nUsage:\n v23 version\n\nV23 Xgo\n\nWrapper around the 'go' tool that can be used for cross-compilation of vanadium\nGo sources. It takes care of vanadium-specific setup, such as setting up the Go\nspecific environment variables or making sure that VDL generated files are\nregenerated before compilation.\n\nIn particular, the tool invokes the following command before invoking any go\ntool commands that compile vanadium Go code:\n\nvdl generate -lang=go all\n\nUsage:\n v23 xgo [flags] <platform> <arg ...>\n\n<platform> is the cross-compilation target and has the general format\n<arch><sub>-<os> or <arch><sub>-<os>-<env> where: - <arch> is the platform\narchitecture (e.g. 386, amd64 or arm) - <sub> is the platform sub-architecture\n(e.g. v6 or v7 for arm) - <os> is the platform operating system (e.g. linux or\ndarwin) - <env> is the platform environment (e.g. gnu or android)\n\n<arg ...> is a list of arguments for the go tool.\"\n\nThe v23 xgo flags are:\n -host_go=go\n Go command for the host platform.\n -target_go=go\n Go command for the target platform.\n\nV23 Help\n\nHelp with no args displays the usage of the parent command.\n\nHelp with args displays the usage of the specified sub-command or help topic.\n\n\"help ...\" recursively displays help for all commands and topics.\n\nThe output is formatted to a target width in runes. The target width is\ndetermined by checking the environment variable CMDLINE_WIDTH, falling back on\nthe terminal width from the OS, falling back on 80 chars. By setting\nCMDLINE_WIDTH=x, if x > 0 the width is x, if x < 0 the width is unlimited, and\nif x == 0 or is unset one of the fallbacks is used.\n\nUsage:\n v23 help [flags] [command\/topic ...]\n\n[command\/topic ...] optionally identifies a specific sub-command or help topic.\n\nThe v23 help flags are:\n -style=text\n The formatting style for help output, either \"text\" or \"godoc\".\n*\/\npackage main\n<commit_msg>Post-migration cleanup.<commit_after>\/\/ This file was auto-generated via go generate.\n\/\/ DO NOT UPDATE MANUALLY\n\n\/*\nThe v23 tool helps manage vanadium development.\n\nUsage:\n v23 [flags] <command>\n\nThe v23 commands are:\n buildcop Manage vanadium build cop schedule\n contributors List vanadium project contributors\n env Print vanadium environment variables\n go Execute the go tool using the vanadium environment\n goext Vanadium extensions of the go tool\n profile Manage vanadium profiles\n project Manage the vanadium projects\n run Run an executable using the vanadium environment\n snapshot Manage snapshots of the vanadium project\n test Manage vanadium tests\n update Update all vanadium tools and projects\n version Print version\n xgo Execute the go tool using the vanadium environment and\n cross-compilation\n help Display help for commands or topics\nRun \"v23 help [command]\" for command usage.\n\nThe v23 flags are:\n -n=false\n Show what commands will run but do not execute them.\n -nocolor=false\n Do not use color to format output.\n -v=false\n Print verbose output.\n\nV23 Buildcop\n\nManage vanadium build cop schedule. If no subcommand is given, it shows the LDAP\nof the current build cop.\n\nUsage:\n v23 buildcop <command>\n v23 buildcop\n\nThe v23 buildcop commands are:\n list List available build cop schedule\n\nV23 Buildcop List\n\nList available build cop schedule.\n\nUsage:\n v23 buildcop list\n\nV23 Contributors\n\nLists vanadium project contributors and the number of their commits. Vanadium\nprojects to consider can be specified as an argument. If no projects are\nspecified, all vanadium projects are considered by default.\n\nUsage:\n v23 contributors <projects>\n\n<projects> is a list of projects to consider.\n\nV23 Env\n\nPrint vanadium environment variables.\n\nIf no arguments are given, prints all variables in NAME=\"VALUE\" format, each on\na separate line ordered by name. This format makes it easy to set all vars by\nrunning the following bash command (or similar for other shells):\n eval $(v23 env)\n\nIf arguments are given, prints only the value of each named variable, each on a\nseparate line in the same order as the arguments.\n\nUsage:\n v23 env [flags] [name ...]\n\n[name ...] is an optional list of variable names.\n\nThe v23 env flags are:\n -platform=\n Target platform.\n\nV23 Go\n\nWrapper around the 'go' tool that can be used for compilation of vanadium Go\nsources. It takes care of vanadium-specific setup, such as setting up the Go\nspecific environment variables or making sure that VDL generated files are\nregenerated before compilation.\n\nIn particular, the tool invokes the following command before invoking any go\ntool commands that compile vanadium Go code:\n\nvdl generate -lang=go all\n\nUsage:\n v23 go [flags] <arg ...>\n\n<arg ...> is a list of arguments for the go tool.\n\nThe v23 go flags are:\n -host_go=go\n Go command for the host platform.\n -target_go=go\n Go command for the target platform.\n\nV23 Goext\n\nVanadium extension of the go tool.\n\nUsage:\n v23 goext <command>\n\nThe v23 goext commands are:\n distclean Restore the vanadium Go workspaces to their pristine state\n\nV23 Goext Distclean\n\nUnlike the 'go clean' command, which only removes object files for packages in\nthe source tree, the 'goext disclean' command removes all object files from\nvanadium Go workspaces. This functionality is needed to avoid accidental use of\nstale object files that correspond to packages that no longer exist in the\nsource tree.\n\nUsage:\n v23 goext distclean\n\nV23 Profile\n\nTo facilitate development across different platforms, vanadium defines\nplatform-independent profiles that map different platforms to a set of libraries\nand tools that can be used for a factor of vanadium development.\n\nUsage:\n v23 profile <command>\n\nThe v23 profile commands are:\n list List known vanadium profiles\n setup Set up the given vanadium profiles\n\nV23 Profile List\n\nList known vanadium profiles.\n\nUsage:\n v23 profile list\n\nV23 Profile Setup\n\nSet up the given vanadium profiles.\n\nUsage:\n v23 profile setup <profiles>\n\n<profiles> is a list of profiles to set up.\n\nV23 Project\n\nManage the vanadium projects.\n\nUsage:\n v23 project [flags] <command>\n\nThe v23 project commands are:\n list List existing vanadium projects and branches\n shell-prompt Print a succinct status of projects, suitable for shell prompts\n poll Poll existing vanadium projects\n\nThe v23 project flags are:\n -manifest=default\n Name of the project manifest.\n\nV23 Project List\n\nInspect the local filesystem and list the existing projects and branches.\n\nUsage:\n v23 project list [flags]\n\nThe v23 project list flags are:\n -branches=false\n Show project branches.\n -nopristine=false\n If true, omit pristine projects, i.e. projects with a clean master branch and\n no other branches.\n\nV23 Project Shell-Prompt\n\nReports current branches of vanadium projects (repositories) as well as an\nindication of each project's status:\n * indicates that a repository contains uncommitted changes\n % indicates that a repository contains untracked files\n\nUsage:\n v23 project shell-prompt [flags]\n\nThe v23 project shell-prompt flags are:\n -check_dirty=true\n If false, don't check for uncommitted changes or untracked files. Setting\n this option to false is dangerous: dirty master branches will not appear in\n the output.\n -show_current_repo_name=false\n Show the name of the current repo.\n\nV23 Project Poll\n\nPoll vanadium projects that can affect the outcome of the given tests and report\nwhether any new changes in these projects exist. If no tests are specified, all\nprojects are polled by default.\n\nUsage:\n v23 project poll <test ...>\n\n<test ...> is a list of tests that determine what projects to poll.\n\nV23 Run\n\nRun an executable using the vanadium environment.\n\nUsage:\n v23 run <executable> [arg ...]\n\n<executable> [arg ...] is the executable to run and any arguments to pass\nverbatim to the executable.\n\nV23 Snapshot\n\nThe \"v23 snapshot\" command can be used to manage snapshots of the vanadium\nproject. In particular, it can be used to create new snapshots and to list\nexisting snapshots.\n\nThe command-line flag \"-remote\" determines whether the command pertains to\n\"local\" snapshots that are only stored locally or \"remote\" snapshots the are\nrevisioned in the manifest repository.\n\nUsage:\n v23 snapshot [flags] <command>\n\nThe v23 snapshot commands are:\n create Create a new snapshot of the vanadium project\n list List existing snapshots of vanadium projects\n\nThe v23 snapshot flags are:\n -remote=false\n Manage remote snapshots.\n\nV23 Snapshot Create\n\nThe \"v23 snapshot create <label>\" command first checks whether the vanadium\nproject configuration associates the given label with any tests. If so, the\ncommand checks that all of these tests pass.\n\nNext, the command captures the current state of the vanadium project as a\nmanifest and, depending on the value of the -remote flag, the command either\nstores the manifest in the local $VANADIUM_ROOT\/.snapshots directory, or in the\nmanifest repository, pushing the change to the remote repository and thus making\nit available globally.\n\nInternally, snapshots are organized as follows:\n\n <snapshot-dir>\/\n labels\/\n <label1>\/\n <label1-snapshot1>\n <label1-snapshot2>\n ...\n <label2>\/\n <label2-snapshot1>\n <label2-snapshot2>\n ...\n <label3>\/\n ...\n <label1> # a symlink to the latest <label1-snapshot*>\n <label2> # a symlink to the latest <label2-snapshot*>\n ...\n\nNOTE: Unlike the v23 tool commands, the above internal organization is not an\nAPI. It is an implementation and can change without notice.\n\nUsage:\n v23 snapshot create <label>\n\n<label> is the snapshot label.\n\nV23 Snapshot List\n\nThe \"snapshot list\" command lists existing snapshots of the labels specified as\ncommand-line arguments. If no arguments are provided, the command lists\nsnapshots for all known labels.\n\nUsage:\n v23 snapshot list <label ...>\n\n<label ...> is a list of snapshot labels.\n\nV23 Test\n\nManage vanadium tests.\n\nUsage:\n v23 test <command>\n\nThe v23 test commands are:\n project Run tests for a vanadium project\n run Run vanadium tests\n list List vanadium tests\n\nV23 Test Project\n\nRuns tests for a vanadium project that is by the remote URL specified as the\ncommand-line argument. Projects hosted on googlesource.com, can be specified\nusing the basename of the URL (e.g. \"vanadium.go.core\" implies\n\"https:\/\/vanadium.googlesource.com\/vanadium.go.core\").\n\nUsage:\n v23 test project <project>\n\n<project> identifies the project for which to run tests.\n\nV23 Test Run\n\nRun vanadium tests.\n\nUsage:\n v23 test run <name ...>\n\n<name ...> is a list names identifying the tests to run.\n\nV23 Test List\n\nList vanadium tests.\n\nUsage:\n v23 test list\n\nV23 Update\n\nUpdates all vanadium projects, builds the latest version of vanadium tools, and\ninstalls the resulting binaries into $VANADIUM_ROOT\/bin. The sequence in which\nthe individual updates happen guarantees that we end up with a consistent set of\ntools and source code.\n\nThe set of project and tools to update is describe by a manifest. Vanadium\nmanifests are revisioned and stored in a \"manifest\" repository, that is\navailable locally in $VANADIUM_ROOT\/.manifest. The manifest uses the following\nXML schema:\n\n <manifest>\n <imports>\n <import name=\"default\"\/>\n ...\n <\/imports>\n <projects>\n <project name=\"https:\/\/vanadium.googlesource.com\/vanadium.go.core\"\n path=\"release\/go\/src\/v.io\/core\"\n protocol=\"git\"\n revision=\"HEAD\"\/>\n ...\n <\/projects>\n <tools>\n <tool name=\"v23\" package=\"v.io\/tools\/v23\"\/>\n ...\n <\/tools>\n <\/manifest>\n\nThe <import> element can be used to share settings across multiple manifests.\nImport names are interpreted relative to the $VANADIUM_ROOT\/.manifest\/v1\ndirectory. Import cycles are not allowed and if a project or a tool is specified\nmultiple times, the last specification takes effect. In particular, the elements\n<project name=\"foo\" exclude=\"true\"\/> and <tool name=\"bar\" exclude=\"true\"\/> can\nbe used to exclude previously included projects and tools.\n\nThe tool identifies which manifest to use using the following algorithm. If the\n$VANADIUM_ROOT\/.local_manifest file exists, then it is used. Otherwise, the\n$VANADIUM_ROOT\/.manifest\/v1\/<manifest>.xml file is used, which <manifest> is the\nvalue of the -manifest command-line flag, which defaults to \"default\".\n\nNOTE: Unlike the v23 tool commands, the above manifest file format is not an\nAPI. It is an implementation and can change without notice.\n\nUsage:\n v23 update [flags]\n\nThe v23 update flags are:\n -gc=false\n Garbage collect obsolete repositories.\n -manifest=default\n Name of the project manifest.\n\nV23 Version\n\nPrint version of the v23 tool.\n\nUsage:\n v23 version\n\nV23 Xgo\n\nWrapper around the 'go' tool that can be used for cross-compilation of vanadium\nGo sources. It takes care of vanadium-specific setup, such as setting up the Go\nspecific environment variables or making sure that VDL generated files are\nregenerated before compilation.\n\nIn particular, the tool invokes the following command before invoking any go\ntool commands that compile vanadium Go code:\n\nvdl generate -lang=go all\n\nUsage:\n v23 xgo [flags] <platform> <arg ...>\n\n<platform> is the cross-compilation target and has the general format\n<arch><sub>-<os> or <arch><sub>-<os>-<env> where: - <arch> is the platform\narchitecture (e.g. 386, amd64 or arm) - <sub> is the platform sub-architecture\n(e.g. v6 or v7 for arm) - <os> is the platform operating system (e.g. linux or\ndarwin) - <env> is the platform environment (e.g. gnu or android)\n\n<arg ...> is a list of arguments for the go tool.\"\n\nThe v23 xgo flags are:\n -host_go=go\n Go command for the host platform.\n -target_go=go\n Go command for the target platform.\n\nV23 Help\n\nHelp with no args displays the usage of the parent command.\n\nHelp with args displays the usage of the specified sub-command or help topic.\n\n\"help ...\" recursively displays help for all commands and topics.\n\nThe output is formatted to a target width in runes. The target width is\ndetermined by checking the environment variable CMDLINE_WIDTH, falling back on\nthe terminal width from the OS, falling back on 80 chars. By setting\nCMDLINE_WIDTH=x, if x > 0 the width is x, if x < 0 the width is unlimited, and\nif x == 0 or is unset one of the fallbacks is used.\n\nUsage:\n v23 help [flags] [command\/topic ...]\n\n[command\/topic ...] optionally identifies a specific sub-command or help topic.\n\nThe v23 help flags are:\n -style=text\n The formatting style for help output, either \"text\" or \"godoc\".\n*\/\npackage main\n<|endoftext|>"} {"text":"<commit_before>package valente\n\nimport (\n\t\"log\"\n\n\t\"golang.org\/x\/net\/websocket\"\n)\n\n\/\/HandlerFunc is a function of handle an

For the use of this\npackage on Windows and Plan 9, see below.\n\n# Types of signals\n\nThe signals SIGKILL and SIGSTOP may not be caught by a program, and\ntherefore cannot be affected by this package.\n\nSynchronous signals are signals triggered by errors in program\nexecution: SIGBUS, SIGFPE, and SIGSEGV. These are only considered\nsynchronous when caused by program execution, not when sent using\nos.Process.Kill or the kill program or some similar mechanism. In\ngeneral, except as discussed below, Go programs will convert a\nsynchronous signal into a run-time panic.\n\nThe remaining signals are asynchronous signals. They are not\ntriggered by program errors, but are instead sent from the kernel or\nfrom some other program.\n\nOf the asynchronous signals, the SIGHUP signal is sent when a program\nloses its controlling terminal. The SIGINT signal is sent when the\nuser at the controlling terminal presses the interrupt character,\nwhich by default is ^C (Control-C). The SIGQUIT signal is sent when\nthe user at the controlling terminal presses the quit character, which\nby default is ^\\ (Control-Backslash). In general you can cause a\nprogram to simply exit by pressing ^C, and you can cause it to exit\nwith a stack dump by pressing ^\\.\n\n# Default behavior of signals in Go programs\n\nBy default, a synchronous signal is converted into a run-time panic. A\nSIGHUP, SIGINT, or SIGTERM signal causes the program to exit. A\nSIGQUIT, SIGILL, SIGTRAP, SIGABRT, SIGSTKFLT, SIGEMT, or SIGSYS signal\ncauses the program to exit with a stack dump. A SIGTSTP, SIGTTIN, or\nSIGTTOU signal gets the system default behavior (these signals are\nused by the shell for job control). The SIGPROF signal is handled\ndirectly by the Go runtime to implement runtime.CPUProfile. Other\nsignals will be caught but no action will be taken.\n\nIf the Go program is started with either SIGHUP or SIGINT ignored\n(signal handler set to SIG_IGN), they will remain ignored.\n\nIf the Go program is started with a non-empty signal mask, that will\ngenerally be honored. However, some signals are explicitly unblocked:\nthe synchronous signals, SIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF,\nand, on Linux, signals 32 (SIGCANCEL) and 33 (SIGSETXID)\n(SIGCANCEL and SIGSETXID are used internally by glibc). Subprocesses\nstarted by os.Exec, or by the os\/exec package, will inherit the\nmodified signal mask.\n\n# Changing the behavior of signals in Go programs\n\nThe functions in this package allow a program to change the way Go\nprograms handle signals.\n\nNotify disables the default behavior for a given set of asynchronous\nsignals and instead delivers them over one or more registered\nchannels. Specifically, it applies to the signals SIGHUP, SIGINT,\nSIGQUIT, SIGABRT, and SIGTERM. It also applies to the job control\nsignals SIGTSTP, SIGTTIN, and SIGTTOU, in which case the system\ndefault behavior does not occur. It also applies to some signals that\notherwise cause no action: SIGUSR1, SIGUSR2, SIGPIPE, SIGALRM,\nSIGCHLD, SIGCONT, SIGURG, SIGXCPU, SIGXFSZ, SIGVTALRM, SIGWINCH,\nSIGIO, SIGPWR, SIGSYS, SIGINFO, SIGTHR, SIGWAITING, SIGLWP, SIGFREEZE,\nSIGTHAW, SIGLOST, SIGXRES, SIGJVM1, SIGJVM2, and any real time signals\nused on the system. Note that not all of these signals are available\non all systems.\n\nIf the program was started with SIGHUP or SIGINT ignored, and Notify\nis called for either signal, a signal handler will be installed for\nthat signal and it will no longer be ignored. If, later, Reset or\nIgnore is called for that signal, or Stop is called on all channels\npassed to Notify for that signal, the signal will once again be\nignored. Reset will restore the system default behavior for the\nsignal, while Ignore will cause the system to ignore the signal\nentirely.\n\nIf the program is started with a non-empty signal mask, some signals\nwill be explicitly unblocked as described above. If Notify is called\nfor a blocked signal, it will be unblocked. If, later, Reset is\ncalled for that signal, or Stop is called on all channels passed to\nNotify for that signal, the signal will once again be blocked.\n\n# SIGPIPE\n\nWhen a Go program writes to a broken pipe, the kernel will raise a\nSIGPIPE signal.\n\nIf the program has not called Notify to receive SIGPIPE signals, then\nthe behavior depends on the file descriptor number. A write to a\nbroken pipe on file descriptors 1 or 2 (standard output or standard\nerror) will cause the program to exit with a SIGPIPE signal. A write\nto a broken pipe on some other file descriptor will take no action on\nthe SIGPIPE signal, and the write will fail with an EPIPE error.\n\nIf the program has called Notify to receive SIGPIPE signals, the file\ndescriptor number does not matter. The SIGPIPE signal will be\ndelivered to the Notify channel, and the write will fail with an EPIPE\nerror.\n\nThis means that, by default, command line programs will behave like\ntypical Unix command line programs, while other programs will not\ncrash with SIGPIPE when writing to a closed network connection.\n\n# Go programs that use cgo or SWIG\n\nIn a Go program that includes non-Go code, typically C\/C++ code\naccessed using cgo or SWIG, Go's startup code normally runs first. It\nconfigures the signal handlers as expected by the Go runtime, before\nthe non-Go startup code runs. If the non-Go startup code wishes to\ninstall its own signal handlers, it must take certain steps to keep Go\nworking well. This section documents those steps and the overall\neffect changes to signal handler settings by the non-Go code can have\non Go programs. In rare cases, the non-Go code may run before the Go\ncode, in which case the next section also applies.\n\nIf the non-Go code called by the Go program does not change any signal\nhandlers or masks, then the behavior is the same as for a pure Go\nprogram.\n\nIf the non-Go code installs any signal handlers, it must use the\nSA_ONSTACK flag with sigaction. Failing to do so is likely to cause\nthe program to crash if the signal is received. Go programs routinely\nrun with a limited stack, and therefore set up an alternate signal\nstack.\n\nIf the non-Go code installs a signal handler for any of the\nsynchronous signals (SIGBUS, SIGFPE, SIGSEGV), then it should record\nthe existing Go signal handler. If those signals occur while\nexecuting Go code, it should invoke the Go signal handler (whether the\nsignal occurs while executing Go code can be determined by looking at\nthe PC passed to the signal handler). Otherwise some Go run-time\npanics will not occur as expected.\n\nIf the non-Go code installs a signal handler for any of the\nasynchronous signals, it may invoke the Go signal handler or not as it\nchooses. Naturally, if it does not invoke the Go signal handler, the\nGo behavior described above will not occur. This can be an issue with\nthe SIGPROF signal in particular.\n\nThe non-Go code should not change the signal mask on any threads\ncreated by the Go runtime. If the non-Go code starts new threads of\nits own, it may set the signal mask as it pleases.\n\nIf the non-Go code starts a new thread, changes the signal mask, and\nthen invokes a Go function in that thread, the Go runtime will\nautomatically unblock certain signals: the synchronous signals,\nSIGILL, SIGTRAP, SIGSTKFLT, SIGCHLD, SIGPROF, SIGCANCEL, and\nSIGSETXID. When the Go function returns, the non-Go signal mask will\nbe restored.\n\nIf the Go signal handler is invoked on a non-Go thread not running Go\ncode, the handler generally forwards the signal to the non-Go code, as\nfollows. If the signal is SIGPROF, the Go handler does\nnothing. Otherwise, the Go handler removes itself, unblocks the\nsignal, and raises it again, to invoke any non-Go handler or default\nsystem handler. If the program does not exit, the Go handler then\nreinstalls itself and continues execution of the program.\n\n# Non-Go programs that call Go code\n\nWhen Go code is built with options like -buildmode=c-shared, it will\nbe run as part of an existing non-Go program. The non-Go code may\nhave already installed signal handlers when the Go code starts (that\nmay also happen in unusual cases when using cgo or SWIG; in that case,\nthe discussion here applies). For -buildmode=c-archive the Go runtime\nwill initialize signals at global constructor time. For\n-buildmode=c-shared the Go runtime will initialize signals when the\nshared library is loaded.\n\nIf the Go runtime sees an existing signal handler for the SIGCANCEL or\nSIGSETXID signals (which are used only on Linux), it will turn on\nthe SA_ONSTACK flag and otherwise keep the signal handler.\n\nFor the synchronous signals and SIGPIPE, the Go runtime will install a\nsignal handler. It will save any existing signal handler. If a\nsynchronous signal arrives while executing non-Go code, the Go runtime\nwill invoke the existing signal handler instead of the Go signal\nhandler.\n\nGo code built with -buildmode=c-archive or -buildmode=c-shared will\nnot install any other signal handlers by default. If there is an\nexisting signal handler, the Go runtime will turn on the SA_ONSTACK\nflag and otherwise keep the signal handler. If Notify is called for an\nasynchronous signal, a Go signal handler will be installed for that\nsignal. If, later, Reset is called for that signal, the original\nhandling for that signal will be reinstalled, restoring the non-Go\nsignal handler if any.\n\nGo code built without -buildmode=c-archive or -buildmode=c-shared will\ninstall a signal handler for the asynchronous signals listed above,\nand save any existing signal handler. If a signal is delivered to a\nnon-Go thread, it will act as described above, except that if there is\nan existing non-Go signal handler, that handler will be installed\nbefore raising the signal.\n\n# Windows\n\nOn Windows a ^C (Control-C) or ^BREAK (Control-Break) normally cause\nthe program to exit. If Notify is called for os.Interrupt, ^C or ^BREAK\nwill cause os.Interrupt to be sent on the channel, and the program will\nnot exit. If Reset is called, or Stop is called on all channels passed\nto Notify, then the default behavior will be restored.\n\nAdditionally, if Notify is called, and Windows sends CTRL_CLOSE_EVENT,\nCTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT to the process, Notify will\nreturn syscall.SIGTERM. Unlike Control-C and Control-Break, Notify does\nnot change process behavior when either CTRL_CLOSE_EVENT,\nCTRL_LOGOFF_EVENT or CTRL_SHUTDOWN_EVENT is received - the process will\nstill get terminated unless it exits. But receiving syscall.SIGTERM will\ngive the process an opportunity to clean up before termination.\n\n# Plan 9\n\nOn Plan 9, signals have type syscall.Note, which is a string. Calling\nNotify with a syscall.Note will cause that value to be sent on the\nchannel when that string is posted as a note.\n*\/\npackage signal\n<commit_msg>os\/signal: document behavior of SIGPIPE on non-Go thread<commit_after>\/\/ Copyright 2015 The Go Authors.

For the use of this\npackage on Windows and Plan 9, see below.\n\n# Types of signals\n\nThe signals SIGKILL and SIGSTOP may not be caught by a program, and\ntherefore cannot be affected by this package.\n\nSynchronous signals are signals triggered by errors in program\nexecution: SIGBUS, SIGFPE, and SIGSEGV. These are only considered\nsynchronous when caused by program execution, not when sent using\nos.Process.Kill or the kill program or some similar mechanism. In\ngeneral, except as discussed below, Go programs will convert a\nsynchronous signal into a run-time panic.\n\nThe remaining signals are asynchronous signals. They are not\ntriggered by program errors, but are instead sent from the kernel or\nfrom some other program.\n\nOf the asynchronous signals, the SIGHUP signal is sent when a program\nloses its controlling terminal. The SIGINT signal is sent when the\nuser at the controlling terminal presses the interrupt character,\nwhich by default is ^C (Control-C). The SIGQUIT signal is sent when\nthe user at the controlling terminal presses the quit character, which\nby default is ^\\ (Control-Backslash). In general you can cause a\nprogram to simply exit by pressing ^C, and you can cause it to exit\nwith a stack dump by pressing ^\\.\n\n# Default behavior of signals in Go programs\n\nBy default, a synchronous signal is converted into a run-time panic.

But every so often you want to 'remaster'\nyour golden. For example, perhaps the game logic has changed to have slightly\ndifferent behavior, or you want to update the format of the golden to ensure\nit's canonical and up-to-date, to match changes in the underlying library.\n\nIt's possible to 'remaster' goldens, which means to re-record them and overwrite\nthe original. You do this by passing true as the last value to Compare or\nCompareFolder. The `golden_test.go` that is generated for you will also\nautomatically add a flag that will be passed in, so the canonical way to\nremaster is to run `go test -update-golden`, which instead of comparing the\ngolden, will remaster it, overwriting the original.\n\nAfter you remaster, it's a good idea to sanity check by doing a normal test (`go\ntest`) to verify the game logic matches the new golden. You should also visually\ninspect the diff of the golden before commiting to make sure there aren't any\nunintended changes. The remastering process is designed to ensure that wherever\npossible content doesn't change. The design of filesystem.record.Record\n(described above) helps, but the remastering process also seeks to, for example,\nuse existing timestamps wherever possible and generate reasonable intermediate\ntimestamps for new moves that have been added.\n\n*\/\npackage golden\n\nimport (\n\t\"bytes\"\n\t\"encoding\/json\"\n\t\"errors\"\n\t\"fmt\"\n\t\"io\/ioutil\"\n\t\"path\/filepath\"\n\t\"reflect\"\n\t\"strings\"\n\n\t\"github.com\/go-test\/deep\"\n\t\"github.com\/jkomoros\/boardgame\"\n\t\"github.com\/jkomoros\/boardgame\/storage\/filesystem\/record\"\n\t\"github.com\/sirupsen\/logrus\"\n\t\"github.com\/yudai\/gojsondiff\"\n\t\"github.com\/yudai\/gojsondiff\/formatter\"\n)\n\n\/\/Compare is the primary method in the package.

An analysis that reports mistakes is informally called a\n\"checker\". For example, the printf checker reports mistakes in\nfmt.Printf format strings.\n\nA \"modular\" analysis is one that inspects one package at a time but can\nsave information from a lower-level package and use it when inspecting a\nhigher-level package, analogous to separate compilation in a toolchain.\nThe printf checker is modular: when it discovers that a function such as\nlog.Fatalf delegates to fmt.Printf, it records this fact, and checks\ncalls to that function too, including calls made from another package.\n\nBy implementing a common interface, checkers from a variety of sources\ncan be easily selected, incorporated, and reused in a wide range of\ndriver programs including command-line tools (such as vet), text editors and\nIDEs, build and test systems (such as go build, Bazel, or Buck), test\nframeworks, code review tools, code-base indexers (such as SourceGraph),\ndocumentation viewers (such as godoc), batch pipelines for large code\nbases, and so on.\n\n\nAnalyzer\n\nThe primary type in the API is Analyzer. An Analyzer statically\ndescribes an analysis function: its name, documentation, flags,\nrelationship to other analyzers, and of course, its logic.\n\nTo define an analysis, a user declares a (logically constant) variable\nof type Analyzer.

A driver for a single analysis, a, might expose its flag\nf directly on the command line as -f, whereas a driver for multiple\nanalyses might prefix the flag name by the analysis name (-a.f) to avoid\nambiguity. An IDE might expose the flags through a graphical interface,\nand a batch pipeline might configure them from a config file.\nSee the \"findcall\" analyzer for an example of flags in action.\n\nThe RunDespiteErrors flag indicates whether the analysis is equipped to\nhandle ill-typed code. If not, the driver will skip the analysis if\nthere were parse or type errors.\nThe optional ResultType field specifies the type of the result value\ncomputed by this analysis and made available to other analyses.\nThe Requires field specifies a list of analyses upon which\nthis one depends and whose results it may access, and it constrains the\norder in which a driver may run analyses.\nThe FactTypes field is discussed in the section on Modularity.\nThe analysis package provides a Validate function to perform basic\nsanity checks on an Analyzer, such as that its Requires graph is\nacyclic, its fact and result types are unique, and so on.\n\nFinally, the Run field contains a function to be called by the driver to\nexecute the analysis on a single package. The driver passes it an\ninstance of the Pass type.\n\n\nPass\n\nA Pass describes a single unit of work: the application of a particular\nAnalyzer to a particular package of Go code.\nThe Pass provides information to the Analyzer's Run function about the\npackage being analyzed, and provides operations to the Run function for\nreporting diagnostics and other information back to the driver.\n\n\ttype Pass struct {\n\t\tFset \t\t*token.FileSet\n\t\tFiles\t\t[]*ast.File\n\t\tOtherFiles\t[]string\n\t\tPkg\t\t*types.Package\n\t\tTypesInfo\t*types.Info\n\t\tResultOf\tmap[*Analyzer]interface{}\n\t\tReport\t\tfunc(Diagnostic)\n\t\t...\n\t}\n\nThe Fset, Files, Pkg, and TypesInfo fields provide the syntax trees,\ntype information, and source positions for a single package of Go code.\n\nThe OtherFiles field provides the names, but not the contents, of non-Go\nfiles such as assembly that are part of this package. See the \"asmdecl\"\nor \"buildtags\" analyzers for examples of loading non-Go files and report\ndiagnostics against them.\n\nThe ResultOf field provides the results computed by the analyzers\nrequired by this one, as expressed in its Analyzer.Requires field. The\ndriver runs the required analyzers first and makes their results\navailable in this map. Each Analyzer must return a value of the type\ndescribed in its Analyzer.ResultType field.\nFor example, the \"ctrlflow\" analyzer returns a *ctrlflow.CFGs, which\nprovides a control-flow graph for each function in the package (see\ngolang.org\/x\/tools\/go\/cfg); the \"inspect\" analyzer returns a value that\nenables other Analyzers to traverse the syntax trees of the package more\nefficiently; and the \"buildssa\" analyzer constructs an SSA-form\nintermediate representation.\nEach of these Analyzers extends the capabilities of later Analyzers\nwithout adding a dependency to the core API, so an analysis tool pays\nonly for the extensions it needs.\n\nThe Report function emits a diagnostic, a message associated with a\nsource position. For most analyses, diagnostics are their primary\nresult.\nFor convenience, Pass provides a helper method, Reportf, to report a new\ndiagnostic by formatting a string.\nDiagnostic is defined as:\n\n\ttype Diagnostic struct {\n\t\tPos token.Pos\n\t\tCategory string \/\/ optional\n\t\tMessage string\n\t}\n\nThe optional Category field is a short identifier that classifies the\nkind of message when an analysis produces several kinds of diagnostic.\n\nMost Analyzers inspect typed Go syntax trees, but a few, such as asmdecl\nand buildtag, inspect the raw text of Go source files or even non-Go\nfiles such as assembly. To report a diagnostic against a line of a\nraw text file, use the following sequence:\n\n\tcontent, err := ioutil.ReadFile(filename)\n\tif err != nil { ... }\n\ttf := fset.AddFile(filename, -1, len(content))\n\ttf.SetLinesForContent(content)\n\t...\n\tpass.Reportf(tf.LineStart(line), \"oops\")\n\n\nModular analysis with Facts\n\nTo improve efficiency and scalability, large programs are routinely\nbuilt using separate compilation: units of the program are compiled\nseparately, and recompiled only when one of their dependencies changes;\nindependent modules may be compiled in parallel. The same technique may\nbe applied to static analyses, for the same benefits. Such analyses are\ndescribed as \"modular\".\n\nA compiler’s type checker is an example of a modular static analysis.\nMany other checkers we would like to apply to Go programs can be\nunderstood as alternative or non-standard type systems. For example,\nvet's printf checker infers whether a function has the \"printf wrapper\"\ntype, and it applies stricter checks to calls of such functions. In\naddition, it records which functions are printf wrappers for use by\nlater analysis units to identify other printf wrappers by induction.\nA result such as “f is a printf wrapper” that is not interesting by\nitself but serves as a stepping stone to an interesting result (such as\na diagnostic) is called a \"fact\".\n\nThe analysis API allows an analysis to define new types of facts, to\nassociate facts of these types with objects (named entities) declared\nwithin the current package, or with the package as a whole, and to query\nfor an existing fact of a given type associated with an object or\npackage.\n\nAn Analyzer that uses facts must declare their types:\n\n\tvar Analyzer = &analysis.Analyzer{\n\t\tName: \"printf\",\n\t\tFactTypes: []analysis.Fact{new(isWrapper)},\n\t\t...\n\t}\n\n\ttype isWrapper struct{} \/\/ => *types.Func f “is a printf wrapper”\n\nA driver program ensures that facts for a pass’s dependencies are\ngenerated before analyzing the pass and are responsible for propagating\nfacts between from one pass to another, possibly across address spaces.\nConsequently, Facts must be serializable. The API requires that drivers\nuse the gob encoding, an efficient, robust, self-describing binary\nprotocol. A fact type may implement the GobEncoder\/GobDecoder interfaces\nif the default encoding is unsuitable. Facts should be stateless.\n\nThe Pass type has functions to import and export facts,\nassociated either with an object or with a package:\n\n\ttype Pass struct {\n\t\t...\n\t\tExportObjectFact func(types.Object, Fact)\n\t\tImportObjectFact func(types.Object, Fact) bool\n\n\t\tExportPackageFact func(fact Fact)\n\t\tImportPackageFact func(*types.Package, Fact) bool\n\t}\n\nAn Analyzer may only export facts associated with the current package or\nits objects, though it may import facts from any package or object that\nis an import dependency of the current package.\n\nConceptually, ExportObjectFact(obj, fact) inserts fact into a hidden map keyed by\nthe pair (obj, TypeOf(fact)), and the ImportObjectFact function\nretrieves the entry from this map and copies its value into the variable\npointed to by fact. This scheme assumes that the concrete type of fact\nis a pointer; this assumption is checked by the Validate function.\nSee the \"printf\" analyzer for an example of object facts in action.\n\nSome driver implementations (such as those based on Bazel and Blaze) do\nnot currently apply analyzers to packages of the standard library.\nTherefore, for best results, analyzer authors should not rely on\nanalysis facts being available for standard packages.\nFor example, although the printf checker is capable of deducing during\nanalysis of the log package that log.Printf is a printf-wrapper,\nthis fact is built in to the analyzer so that it correctly checks\ncalls to log.Printf even when run in a driver that does not apply\nit to standard packages. We plan to remove this limitation in future.\n\n\nTesting an Analyzer\n\nThe analysistest subpackage provides utilities for testing an Analyzer.\nIn a few lines of code, it is possible to run an analyzer on a package\nof testdata files and check that it reported all the expected\ndiagnostics and facts (and no more). Expectations are expressed using\n\"\/\/ want ...\" comments in the input code.\n\n\nStandalone commands\n\nAnalyzers are provided in the form of packages that a driver program is\nexpected to import. The vet command imports a set of several analyzers,\nbut users may wish to define their own analysis commands that perform\nadditional checks. To simplify the task of creating an analysis command,\neither for a single analyzer or for a whole suite, we provide the\nsinglechecker and multichecker subpackages.\n\nThe singlechecker package provides the main function for a command that\nruns one analyzer. By convention, each analyzer such as\ngo\/passes\/findcall should be accompanied by a singlechecker-based\ncommand such as go\/analysis\/passes\/findcall\/cmd\/findcall, defined in its\nentirety as:\n\n\tpackage main\n\n\timport (\n\t\t\"golang.org\/x\/tools\/go\/analysis\/passes\/findcall\"\n\t\t\"golang.org\/x\/tools\/go\/analysis\/singlechecker\"\n\t)\n\n\tfunc main() { singlechecker.Main(findcall.Analyzer) }\n\nA tool that provides multiple analyzers can use multichecker in a\nsimilar way, giving it the list of Analyzers.\n\n\n\n*\/\npackage analysis\n<commit_msg>go\/analysis: copyedit doc.go<commit_after>\/*\n\nThe analysis package defines the interface between a modular static\nanalysis and an analysis driver program.\n\nBackground\n\nA static analysis is a function that inspects a package of Go code and\nreports a set of diagnostics (typically mistakes in the code), and\nperhaps produces other results as well, such as suggested refactorings\nor other facts. An analysis that reports mistakes is informally called a\n\"checker\". For example, the printf checker reports mistakes in\nfmt.Printf format strings.\n\nA \"modular\" analysis is one that inspects one package at a time but can\nsave information from a lower-level package and use it when inspecting a\nhigher-level package, analogous to separate compilation in a toolchain.\nThe printf checker is modular: when it discovers that a function such as\nlog.Fatalf delegates to fmt.Printf, it records this fact, and checks\ncalls to that function too, including calls made from another package.\n\nBy implementing a common interface, checkers from a variety of sources\ncan be easily selected, incorporated, and reused in a wide range of\ndriver programs including command-line tools (such as vet), text editors and\nIDEs, build and test systems (such as go build, Bazel, or Buck), test\nframeworks, code review tools, code-base indexers (such as SourceGraph),\ndocumentation viewers (such as godoc), batch pipelines for large code\nbases, and so on.\n\n\nAnalyzer\n\nThe primary type in the API is Analyzer.

It stores them with individual expiration time (TTL). The associated\ncontent is stored in binary format. Storing a new item with the same key, overrides the previous one A cached\nitem can be retrieved or deleted with its key. As a special use case, it is possible to store only keys, where\nthe useful information is whether a key exists or not. If a new item doesn't fit in the free space, the least\nrecently used item is evicted (LRU).\n\nKeyspaces\n\nKeyspaces, when used (see NewCacheSpaces()), allow some optimization of the LRU eviction mechanism. Items that\nare more expensive to produce but less frequently accessed than others, can be stored in different keyspaces.\nWhen eviction is required, the cache tries to evict enough items from the same keyspace as the one currently\nbeing filled. When using keyspaces, the same key can appear in different keyspaces pointing to different items.\n\nMemory\n\nThe cache allocates all the used memory on start. To support parallel access, it splits the allocated memory\ninto segments. There are typically as many segments as the maximum of NumCPU() and GOMAXPROCS(). The maximum\nsize of a stored item is the total cache size divided by the number of segments.\n\nThe segments are split into chunks. One cached item can span over multiple chunks, but the chunks cannot be\nshared between the items. This means that the cache is almost never fully utilized. The chunk size is an\ninitialization option, it typically should be a 'couple of times' smaller than the expected size of the 'bulk'\nof the cached items.\n\nThe cache counts the size of the item keys in the used space, but there is some lookup metadata that is not\ncounted: ~24 bytes for each chunk and ~120 bytes for each item.\n\nIO\n\nThe associated data of the keys can be accessed for read, seek and write through the standard Go interfaces. As\na shortcut, the data can be retrieved or set as a single byte slice, too. When using the IO interfaces, the item\ndata can be accessed concurrently, and reading from an item can be started before the write has finished. When\nthe reader reaches a point that was not yet filled by the writer, it blocks, and continues only when more data\nwas written, or returns with EOF once the write was finished.\n\nWhile writing an item, chunks are continuously assigned to the item from the free range of allocated memory. If\nthere are no free chunks, the cache evicts enough of the least recently used items. The cache doesn't evict\nthose items that are currently being read by an unclosed reader. Similarly, when deleting an item or overwriting\none, if it has active readers associated with it, the item is only marked for delete, but the active readers can\nfinish reading from it.\n\nMonitoring\n\nThe cache provides statistics about its internal state, including metrics like item count, effective and used\nsize, active readers and writers. When configured, it also provides change notifications. Depending on the\nconfigured notification mask, it can send events about: cache hit\/miss, evictions, allocation failures, etc.\n*\/\npackage forget\n<commit_msg>fix doc<commit_after>\/*\nPackage forget provides an in-memory cache for arbitrary, binary data.\n\nCaching\n\nThe cache identifies items by their keys.

Note that data and template cannot both come from stdin - at\n least one of the two must be specified via an option.\n\n jgtr can consume data from JSON, YAML 1.1 or TOML v0.2.0. You can specify\n which type to use via an option. If no such option is given, jgtr attempts\n to guess from the extension of the data file (if any). If the format is\n still ambiguous, jgtr uses JSON as the default.\n\nOPTIONS:\n -d FILE, --data=FILE\n Read data data from FILE.

They enable\n\/\/ explicit blocking until the state changes, and also to selectively\n\/\/ unblock select statements accordingly.\n\/\/\n\/\/ For background and a detailed example, see the following blog post:\n\/\/\n\/\/ http:\/\/blog.labix.org\/2011\/10\/09\/death-of-goroutines-under-control\n\/\/\ntype Tomb struct {\n\tm sync.Mutex\n\tDying chan nothing\n\tDead chan nothing\n\treason os.Error\n}\n\n\/\/ New creates a new Tomb to track the lifecycle of a goroutine\n\/\/ that is already alive or about to be created.\nfunc New() *Tomb {\n\treturn &Tomb{Dying: make(chan nothing), Dead: make(chan nothing)}\n}\n\n\/\/ IsDying returns true if the goroutine is in a dying or already dead state.\nfunc (t *Tomb) IsDying() bool {\n\tselect {\n\tcase <-t.Dying:\n\t\treturn true\n\tdefault:\n\t}\n\treturn false\n}\n\n\/\/ IsDead returns true if the goroutine is in a dead state.\nfunc (t *Tomb) IsDead() bool {\n\tselect {\n\tcase <-t.Dead:\n\t\treturn true\n\tdefault:\n\t}\n\treturn false\n}\n\n\/\/ Wait blocks until the goroutine is in a dead state and returns the\n\/\/ reason for its death. The reason may be nil.\nfunc (t *Tomb) Wait() os.Error {\n\t<-t.Dead\n\treturn t.reason\n}\n\n\/\/ Done flags the goroutine as dead, and should be called a single time\n\/\/ right before the goroutine function or method returns.\n\/\/ If the goroutine was not already in a dying state before Done is\n\/\/ called, it will flagged as dying and dead at once.\nfunc (t *Tomb) Done() {\n\tt.Fatal(nil)\n\tclose(t.Dead)\n}\n\n\/\/ Fatal flags the goroutine as dying.\n\/\/ The first non-nil reason parameter to Fatal or the first Fatalf-generated\n\/\/ error is recorded as the reason for the goroutine death.\n\/\/ This method may be safely called concurrently, and may be called both from\n\/\/ within the goroutine and\/or from outside to request the goroutine termination.\nfunc (t *Tomb) Fatal(reason os.Error) {\n\tt.m.Lock()\n\tif t.reason == nil {\n\t\tt.reason = reason\n\t}\n\tselect {\n\tcase <-t.Dying:\n\tdefault:\n\t\tclose(t.Dying)\n\t}\n\tt.m.Unlock()\n}\n\n\/\/ Fatalf works like Fatal, but builds the reason providing the received\n\/\/ arguments to fmt.Errorf.

For example, if the Move has a\n\/\/TargetPlayerIndex property, a reasonable default is state.CurrentPlayer().\ntype MoveFactory func(state State) Move\n\n\/\/Move's are how all modifications are made to Game States after\n\/\/initialization.

The error message may be shown directly to the end-\n\t\/\/user so be sure to make it user friendly. proposer is set to the\n\t\/\/notional player that is proposing the move. proposer might be a valid\n\t\/\/player index, or AdminPlayerIndex (for example, if it is a FixUpMove it\n\t\/\/will typically be AdminPlayerIndex). AdminPlayerIndex is always allowed\n\t\/\/to make any move. It will never be ObserverPlayerIndex, because by\n\t\/\/definition Observers may not make moves.

Fixes #78.<commit_after>package boardgame\n\nimport (\n\t\"encoding\/json\"\n)\n\n\/\/A MoveFactory takes a state and returns a Move. The state may be nil, in\n\/\/which case it should just be an empty (generally, zero-valued) Move of the\n\/\/given type. If state is non-nil, the move that is returned should be set to\n\/\/reasonable defaults for the given state. For example, if the Move has a\n\/\/TargetPlayerIndex property, a reasonable default is state.CurrentPlayer().\ntype MoveFactory func(state State) Move\n\n\/\/Move's are how all modifications are made to Game States after\n\/\/initialization. Packages define structs that implement Move for all\n\/\/modifications. The Move should be JSON-able (that is, all persistable state\n\/\/should be in public fields).\ntype Move interface {\n\t\/\/Legal returns nil if this proposed move is legal, or an error if the\n\t\/\/move is not legal. The error message may be shown directly to the end-\n\t\/\/user so be sure to make it user friendly. proposer is set to the\n\t\/\/notional player that is proposing the move. proposer might be a valid\n\t\/\/player index, or AdminPlayerIndex (for example, if it is a FixUpMove it\n\t\/\/will typically be AdminPlayerIndex). AdminPlayerIndex is always allowed\n\t\/\/to make any move. It will never be ObserverPlayerIndex, because by\n\t\/\/definition Observers may not make moves. If you want to check that the\n\t\/\/person proposing is able to apply the move for the given player, and\n\t\/\/that it is their turn, you would do something like test\n\t\/\/m.TargetPlayerIndex.Equivalent(proposer),\n\t\/\/m.TargetPlayerIndex.Equivalent(game.CurrentPlayer).\n\tLegal(state State, proposer PlayerIndex) error\n\n\t\/\/Apply applies the move to the state. It is handed a copy of the state to\n\t\/\/modify. If error is non-nil it will not be applied to the game. It\n\t\/\/should not be called directly; use Game.ProposeMove.\n\tApply(state MutableState) error\n\n\t\/\/If ImmediateFixUp returns a Move, it will immediately be applied (if\n\t\/\/Legal) to the game before Delegate's ProposeFixUp is consulted. The move\n\t\/\/returned need not have been registered with the GameManager via\n\t\/\/AddFixUpMove, and if the returned move is not legal is fine, it just\n\t\/\/won't be applied. ImmediateFixUp is useful when you've broken a fixup\n\t\/\/task into multiple moves only so the observable semantics are granular\n\t\/\/enough, and saves awkward and error-prone signaling in State fields.\n\t\/\/When in doubt, just return nil for this method.\n\tImmediateFixUp(state State) Move\n\n\t\/\/Name should return the name for this type of move. No other Move structs\n\t\/\/in use in this game should have the same name, but it should be human-\n\t\/\/friendly. For example, \"Place Token\" is a reasonable name, as long as no\n\t\/\/other types of Move-structs will return that name in this game. Name()\n\t\/\/should be the same for every Move of the same type, so this method\n\t\/\/should generally return a constant.\n\tName() string\n\n\t\/\/Description is a human-readable sentence describing what the move does.\n\t\/\/Description should be the same for all moves of the same type, and\n\t\/\/should not vary with the Move's specific properties. For example, the\n\t\/\/Description for \"Place Token\" might be \"Places the current user's token\n\t\/\/in the specified slot on the board.\"\n\tDescription() string\n\n\tReadSetter() PropertyReadSetter\n}\n\n\/\/StorageRecordForMove returns a MoveStorageRecord.

tunRouter is a router for outbound traffic that is centered around a TUN device. It's similar to a\n\/\/ TUN-to-SOCKS5 but uses a bidirectional gRPC tunnel instead of SOCKS when communicating with the\n\/\/ traffic-manager. The addresses of the device are derived from IP addresses sent to it from the user\n\/\/ daemon (which in turn receives them from the cluster).\n\/\/\n\/\/ Data sent to the device is received as L3 IP-packages and parsed into L4 UDP and TCP before they\n\/\/ are dispatched over the tunnel. Returned payloads are wrapped as IP-packages before written\n\/\/ back to the device.\n\/\/\n\/\/ Connection pooling:\n\/\/\n\/\/ For UDP and TCP packages, a ConnID is created which uniquely identifies a combination of protocol,\n\/\/ source IP, source port, destination IP, and destination port. A handler is then obtained that matches\n\/\/ that ID (active handlers are cached in a connpool.Pool) and the package is then sent to that handler.\n\/\/ The handler typically sends the ConnID and the payload of the package over to the traffic-manager\n\/\/ using the gRPC ConnTunnel. At the receiving en din the traffic-manager, a similar connpool.Pool obtains\n\/\/ a corresponding handler which manages a net.Conn matching the ConnID in the cluster.\n\/\/\n\/\/ Negotiation:\n\/\/\n\/\/ UDP is of course very simple. It's fire and forget. There's no negotiation whatsoever.\n\/\/\n\/\/ TCP requires a complete workflow engine on the TUN-device side (see tcp.Handler). All TCP negotiation,\n\/\/ takes place in the client and the same bidirectional tunnel is then used to send both TCP and UDP\n\/\/ packages to the manager. TCP will send some control packages. One to verify that a connection can\n\/\/ be established at the manager side, and one when the connection is closed (from either side).\ntype tunRouter struct {\n\t\/\/ dev is the TUN device that gets configured with the subnets found in the cluster\n\tdev *tun.Device\n\n\t\/\/ managerClient provides the gRPC tunnel to the traffic-manager\n\tmanagerClient manager.ManagerClient\n\n\t\/\/ connStream is the bidirectional gRPC tunnel to the traffic-manager\n\tconnStream *connpool.Stream\n\n\t\/\/ connPool contains handlers that represent active connections.

It's similar to a\n\/\/ TUN-to-SOCKS5 but uses a bidirectional gRPC tunnel instead of SOCKS when communicating with the\n\/\/ traffic-manager. The addresses of the device are derived from IP addresses sent to it from the user\n\/\/ daemon (which in turn receives them from the cluster).\n\/\/\n\/\/ Data sent to the device is received as L3 IP-packages and parsed into L4 UDP and TCP before they\n\/\/ are dispatched over the tunnel. Returned payloads are wrapped as IP-packages before written\n\/\/ back to the device.\n\/\/\n\/\/ Connection pooling:\n\/\/\n\/\/ For UDP and TCP packages, a ConnID is created which uniquely identifies a combination of protocol,\n\/\/ source IP, source port, destination IP, and destination port. A handler is then obtained that matches\n\/\/ that ID (active handlers are cached in a connpool.Pool) and the package is then sent to that handler.\n\/\/ The handler typically sends the ConnID and the payload of the package over to the traffic-manager\n\/\/ using the gRPC ConnTunnel. At the receiving en din the traffic-manager, a similar connpool.Pool obtains\n\/\/ a corresponding handler which manages a net.Conn matching the ConnID in the cluster.\n\/\/\n\/\/ Negotiation:\n\/\/\n\/\/ UDP is of course very simple. It's fire and forget. There's no negotiation whatsoever.\n\/\/\n\/\/ TCP requires a complete workflow engine on the TUN-device side (see tcp.Handler). All TCP negotiation,\n\/\/ takes place in the client and the same bidirectional tunnel is then used to send both TCP and UDP\n\/\/ packages to the manager. TCP will send some control packages. One to verify that a connection can\n\/\/ be established at the manager side, and one when the connection is closed (from either side).\ntype tunRouter struct {\n\t\/\/ dev is the TUN device that gets configured with the subnets found in the cluster\n\tdev *tun.Device\n\n\t\/\/ managerClient provides the gRPC tunnel to the traffic-manager\n\tmanagerClient manager.ManagerClient\n\n\t\/\/ connStream is the bidirectional gRPC tunnel to the traffic-manager\n\tconnStream *connpool.Stream\n\n\t\/\/ connPool contains handlers that represent active connections.

With no arguments, the command will check for the existing registry service\ncalled 'docker-registry' and perform some diagnostics to ensure the registry is properly\nconfigured and functioning.\n\nIf a registry service does not exist, the --create flag can be passed to\ncreate a deployment configuration and service that will run the registry.\n\nTo run a highly available registry, you should be using a remote storage mechanism like an\nobject store (several are supported by the Docker registry). The default Docker registry image\nis configured to accept configuration as environment variables - refer to the config file in\nthat image for more on setting up alternative storage. Once you've made those changes, you can\npass --replicas=2 or higher to ensure you have failover protection. The default registry setup\nuses a local volume and the data will be lost if you delete the running pod.\n\nExamples:\n Check the default Docker registry (\"docker-registry\"):\n\n $ %[1]s %[2]s\n\n See what the registry would look like if created:\n\n $ %[1]s %[2]s -o json\n\n Create a registry if it does not exist with two replicas:\n\n $ %[1]s %[2]s --create --replicas=2\n\n Use a different registry image and see the registry configuration:\n\n $ %[1]s %[2]s -o yaml --images=myrepo\/docker-registry:mytag\n\nALPHA: This command is currently being actively developed. It is intended to simplify\n the tasks of setting up a Docker registry in a new installation.

With no arguments, the command will check for the existing registry service\ncalled 'docker-registry' and perform some diagnostics to ensure the registry is properly\nconfigured and functioning.\n\nIf a registry service does not exist, the --create flag can be passed to\ncreate a deployment configuration and service that will run the registry.\n\nTo run a highly available registry, you should be using a remote storage mechanism like an\nobject store (several are supported by the Docker registry). The default Docker registry image\nis configured to accept configuration as environment variables - refer to the config file in\nthat image for more on setting up alternative storage. Once you've made those changes, you can\npass --replicas=2 or higher to ensure you have failover protection. The default registry setup\nuses a local volume and the data will be lost if you delete the running pod.\n\nExamples:\n Check the default Docker registry (\"docker-registry\"):\n\n $ %[1]s %[2]s\n\n See what the registry would look like if created:\n\n $ %[1]s %[2]s -o json\n\n Create a registry if it does not exist with two replicas:\n\n $ %[1]s %[2]s --create --replicas=2\n\n Use a different registry image and see the registry configuration:\n\n $ %[1]s %[2]s -o yaml --images=myrepo\/docker-registry:mytag\n\nALPHA: This command is currently being actively developed. It is intended to simplify\n the tasks of setting up a Docker registry in a new installation.

It will serve either gzip or identity\n\/\/ content codings (identity meaning no encoding), or return 406 Not\n\/\/ Acceptable status if it can do neither.\n\/\/\n\/\/ It works correctly with handlers which honour Range request headers\n\/\/ (such as http.FileServer) by removing the Range header for requests\n\/\/ which prefer gzip encoding. This is necessary since Range requests\n\/\/ apply to the gzipped content but the wrapped handler is not aware\n\/\/ of the compression when it writes byte ranges. The Accept-Ranges\n\/\/ header is also stripped from corresponding responses.\n\/\/\n\/\/ For requests which prefer gzip encoding a Content-Type header is\n\/\/ set using http.DetectContentType if it is not set by the wrapped\n\/\/ handler.\n\/\/\n\/\/ Using the optimized gzip compressor by Klaus Post\n\/\/\n\/\/ By default, httpgzip uses the standard library gzip implementation\n\/\/ to minimize dependencies. However, there is an excellent optimized\n\/\/ gzip implementation written by Klaus Post that can increase\n\/\/ throughput. To use it instead, first install his compress library:\n\/\/\n\/\/ go get github.com\/klauspost\/compress\n\/\/\n\/\/ and then install httpgzip using the \"klauspost\" build tag:\n\/\/\n\/\/ go install -tags klauspost xi2.org\/x\/httpgzip\n\/\/\n\/\/ Credit is also due to Klaus for his blog post which inspired the\n\/\/ creation of this package and is recommended reading:\n\/\/\n\/\/ https:\/\/blog.klauspost.com\/gzip-performance-for-go-webservers\/\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"fmt\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n\n\t\"xi2.org\/x\/httpgzip\/internal\/gzip\"\n)\n\n\/\/ These constants are copied from the gzip package, so that code that\n\/\/ imports this package does not also have to import \"compress\/gzip\".\nconst (\n\tNoCompression = gzip.NoCompression\n\tBestSpeed = gzip.BestSpeed\n\tBestCompression = gzip.BestCompression\n\tDefaultCompression = gzip.DefaultCompression\n)\n\n\/\/ DefaultContentTypes is the default list of content types for which\n\/\/ a Handler considers gzip compression.

It adds\n\/\/ gzip compression to certain responses, and there are two cases\n\/\/ where this is done. Case 1 is when encs only allows gzip encoding\n\/\/ and forbids identity. Case 2 is when encs prefers gzip encoding,\n\/\/ the response is at least 512 bytes and the response's content type\n\/\/ is in ctMap.\n\/\/\n\/\/ A gzipResponseWriter sets the Content-Encoding and Content-Type\n\/\/ headers when appropriate. It is important to call the Close method\n\/\/ when writing is finished in order to flush and close the\n\/\/ gzipResponseWriter.

It will serve either gzip or identity\n\/\/ content codings (identity meaning no encoding), or return 406 Not\n\/\/ Acceptable status if it can do neither.\n\/\/\n\/\/ It works correctly with handlers which honour Range request headers\n\/\/ (such as http.FileServer) by removing the Range header for requests\n\/\/ which prefer gzip encoding. This is necessary since Range requests\n\/\/ apply to the gzipped content but the wrapped handler is not aware\n\/\/ of the compression when it writes byte ranges. The Accept-Ranges\n\/\/ header is also stripped from corresponding responses.\n\/\/\n\/\/ For requests which prefer gzip encoding a Content-Type header is\n\/\/ set using http.DetectContentType if it is not set by the wrapped\n\/\/ handler.\n\/\/\n\/\/ Using an optimized gzip compressor\n\/\/\n\/\/ By default, httpgzip uses the standard library gzip implementation\n\/\/ to minimize dependencies. However, there is an excellent optimized\n\/\/ gzip implementation written by Klaus Post that can increase\n\/\/ throughput. To use it instead, first install his compress library:\n\/\/\n\/\/ go get github.com\/klauspost\/compress\n\/\/\n\/\/ and then install httpgzip using the \"klauspost\" build tag:\n\/\/\n\/\/ go install -tags klauspost xi2.org\/x\/httpgzip\n\/\/\n\/\/ Credit is also due to Klaus for his blog post which inspired the\n\/\/ creation of this package and is recommended reading:\n\/\/\n\/\/ https:\/\/blog.klauspost.com\/gzip-performance-for-go-webservers\/\npackage httpgzip \/\/ import \"xi2.org\/x\/httpgzip\"\n\nimport (\n\t\"bytes\"\n\t\"fmt\"\n\t\"mime\"\n\t\"net\/http\"\n\t\"strconv\"\n\t\"strings\"\n\t\"sync\"\n\n\t\"xi2.org\/x\/httpgzip\/internal\/gzip\"\n)\n\n\/\/ These constants are copied from the gzip package, so that code that\n\/\/ imports this package does not also have to import \"compress\/gzip\".\nconst (\n\tNoCompression = gzip.NoCompression\n\tBestSpeed = gzip.BestSpeed\n\tBestCompression = gzip.BestCompression\n\tDefaultCompression = gzip.DefaultCompression\n)\n\n\/\/ DefaultContentTypes is the default list of content types for which\n\/\/ a Handler considers gzip compression.

A server registers an object, making it visible\n\tas a service with the name of the type of the object. After registration, public\n\tmethods of the object will be accessible remotely. A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn. More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection. The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection).

A server registers an object, making it visible\n\tas a service with the name of the type of the object. After registration, public\n\tmethods of the object will be accessible remotely. A server may register multiple\n\tobjects (services) of different types but it is an error to register multiple\n\tobjects of the same type.\n\n\tOnly methods that satisfy these criteria will be made available for remote access;\n\tother methods will be ignored:\n\n\t\t- the method name is publicly visible, that is, begins with an upper case letter.\n\t\t- the method has two arguments, both pointers to publicly visible structs.\n\t\t- the method has return type os.Error.\n\n\tThe method's first argument represents the arguments provided by the caller; the\n\tsecond argument represents the result parameters to be returned to the caller.\n\tThe method's return value, if non-nil, is passed back as a string that the client\n\tsees as an os.ErrorString.\n\n\tThe server may handle requests on a single connection by calling ServeConn. More\n\ttypically it will create a network listener and call Accept or, for an HTTP\n\tlistener, HandleHTTP and http.Serve.\n\n\tA client wishing to use the service establishes a connection and then invokes\n\tNewClient on the connection. The convenience function Dial (DialHTTP) performs\n\tboth steps for a raw network connection (an HTTP connection). The resulting\n\tClient object has two methods, Call and Go, that specify the service and method to\n\tcall, a structure containing the arguments, and a structure to receive the result\n\tparameters.\n\n\tCall waits for the remote call to complete; Go launches the call asynchronously\n\tand returns a channel that will signal completion.\n\n\tPackage \"gob\" is used to transport the data.\n\n\tHere is a simple example.

All subsequent commands (such as \"gomote run\" or \"gomote ls\")\nthen proxy your request via the coordinator. To access a buildlet\ndirectly (for example, when working on the buildlet code), you can\nskip the \"gomote create\" step and use the special builder name\n\"<build-config-name>@ip[:port>\", such as \"windows-amd64-2008@10.1.5.3\".\n*\/\npackage main\n\nimport (\n\t\"context\"\n\t\"crypto\/tls\"\n\t\"flag\"\n\t\"fmt\"\n\t\"os\"\n\t\"sort\"\n\t\"strings\"\n\n\t\"golang.org\/x\/build\/buildenv\"\n\t\"golang.org\/x\/build\/buildlet\"\n\t\"golang.org\/x\/build\/internal\/gomote\/protos\"\n\t\"golang.org\/x\/build\/internal\/iapclient\"\n\t\"google.golang.org\/grpc\"\n\t\"google.golang.org\/grpc\/credentials\"\n\t\"google.golang.org\/grpc\/credentials\/oauth\"\n)\n\nvar (\n\tbuildEnv *buildenv.Environment\n)\n\ntype command struct {\n\tname string\n\tdes string\n\trun func([]string) error\n}\n\nvar commands = map[string]command{}\n\nfunc sortedCommands() []string {\n\ts := make([]string, 0, len(commands))\n\tfor name := range commands {\n\t\ts = append(s, name)\n\t}\n\tsort.Strings(s)\n\treturn s\n}\n\nfunc usage() {\n\tfmt.Fprintf(os.Stderr, `Usage of gomote: gomote [global-flags] <cmd> [cmd-flags]\n\nGlobal flags:\n`)\n\tflag.PrintDefaults()\n\tfmt.Fprintf(os.Stderr, \"Commands:\\n\\n\")\n\tfor _, name := range sortedCommands() {\n\t\tfmt.Fprintf(os.Stderr, \" %-10s %s\\n\", name, commands[name].des)\n\t}\n\tos.Exit(1)\n}\n\nfunc registerCommand(name, des string, run func([]string) error) {\n\tif _, dup := commands[name]; dup {\n\t\tpanic(\"duplicate registration of \" + name)\n\t}\n\tcommands[name] = command{\n\t\tname: name,\n\t\tdes: des,\n\t\trun: run,\n\t}\n}\n\nfunc registerCommands() {\n\tregisterCommand(\"create\", \"create a buildlet; with no args, list types of buildlets\", create)\n\tregisterCommand(\"destroy\", \"destroy a buildlet\", destroy)\n\tregisterCommand(\"gettar\", \"extract a tar.gz from a buildlet\", getTar)\n\tregisterCommand(\"ls\", \"list the contents of a directory on a buildlet\", ls)\n\tregisterCommand(\"list\", \"list active buildlets\", list)\n\tregisterCommand(\"ping\", \"test whether a buildlet is alive and reachable \", ping)\n\tregisterCommand(\"push\", \"sync your GOROOT directory to the buildlet\", push)\n\tregisterCommand(\"put\", \"put files on a buildlet\", put)\n\tregisterCommand(\"put14\", \"put Go 1.4 in place\", put14)\n\tregisterCommand(\"puttar\", \"extract a tar.gz to a buildlet\", putTar)\n\tregisterCommand(\"rdp\", \"RDP (Remote Desktop Protocol) to a Windows buildlet\", rdp)\n\tregisterCommand(\"rm\", \"delete files or directories\", rm)\n\tregisterCommand(\"run\", \"run a command on a buildlet\", run)\n\tregisterCommand(\"ssh\", \"ssh to a buildlet\", ssh)\n}\n\nvar (\n\tserverAddr = flag.String(\"server\", \"build.golang.org:443\", \"Address for GRPC server\")\n)\n\nfunc main() {\n\tbuildlet.RegisterFlags()\n\tregisterCommands()\n\tflag.Usage = usage\n\tflag.Parse()\n\tbuildEnv = buildenv.FromFlags()\n\targs := flag.Args()\n\tif len(args) == 0 {\n\t\tusage()\n\t}\n\tcmdName := args[0]\n\tcmd, ok := commands[cmdName]\n\tif !ok {\n\t\tfmt.Fprintf(os.Stderr, \"Unknown command %q\\n\", cmdName)\n\t\tusage()\n\t}\n\terr := cmd.run(args[1:])\n\tif err != nil {\n\t\tfmt.Fprintf(os.Stderr, \"Error running %s: %v\\n\", cmdName, err)\n\t\tos.Exit(1)\n\t}\n}\n\n\/\/ gomoteServerClient returns a gomote server client which can be used to interact with the gomote GRPC server.\n\/\/ It will either retrieve a previously created authentication token or attempt to create a new one.\nfunc gomoteServerClient(ctx context.Context) protos.GomoteServiceClient {\n\tts, err := iapclient.TokenSource(ctx)\n\tif err != nil {\n\t\tlogAndExitf(\"failed to retrieve oauth token: %s\", err)\n\t}\n\topts := []grpc.DialOption{\n\t\tgrpc.WithTransportCredentials(credentials.NewTLS(&tls.Config{InsecureSkipVerify: strings.HasPrefix(*serverAddr, \"localhost:\")})),\n\t\tgrpc.WithDefaultCallOptions(grpc.PerRPCCredentials(oauth.TokenSource{TokenSource: ts})),\n\t\tgrpc.WithBlock(),\n\t}\n\tgrpcClient, err := grpc.DialContext(ctx, *serverAddr, opts...)\n\tif err != nil {\n\t\tlogAndExitf(\"dialing the server=%s failed with: %s\", *serverAddr, err)\n\t}\n\treturn protos.NewGomoteServiceClient(grpcClient)\n}\n\n\/\/ logAndExitf is equivalent to Printf to Stderr followed by a call to os.Exit(1).\nfunc logAndExitf(format string, v ...interface{}) {\n\tfmt.Fprintf(os.Stderr, format, v...)\n\tos.Exit(1)\n}\n<|endoftext|>"} {"text":"<commit_before>\/\/ Copyright 2016 The Go Authors.

Each individual deployment is exposed\nas a new replication controller, and the deployment process manages scaling down old deployments\nand scaling up new ones. You can rollback to any previous deployment, or even scale multiple\ndeployments up at the same time.\n\nThere are several deployment strategies defined:\n\n* Rolling (default) - scales up the new deployment in stages, gradually reducing the number\n of old deployments. If one of the new deployed pods never becomes \"ready\", the new deployment\n will be rolled back (scaled down to zero). Use when your application can tolerate two versions\n of code running at the same time (many web applications, scalable databases)\n* Recreate - scales the old deployment down to zero, then scales the new deployment up to full.\n Use when your application cannot tolerate two versions of code running at the same time\n* Custom - run your own deployment process inside a Docker container using your own scripts.\n\nIf a deployment fails, you may opt to retry it (if the error was transient). Some deployments may\nnever successfully complete - in which case you can use the '--latest' flag to force a redeployment.\nWhen rolling back to a previous deployment, a new deployment will be created with an identical copy\nof your config at the latest position.\n\nIf no options are given, shows information about the latest deployment.`\n\n\tdeployExample = ` # Display the latest deployment for the 'database' deployment config\n $ %[1]s deploy database\n\n # Start a new deployment based on the 'database'\n $ %[1]s deploy database --latest\n\n # Retry the latest failed deployment based on 'frontend'\n # The deployer pod and any hook pods are deleted for the latest failed deployment\n $ %[1]s deploy frontend --retry\n\n # Cancel the in-progress deployment based on 'frontend'\n $ %[1]s deploy frontend --cancel`\n)\n\n\/\/ NewCmdDeploy creates a new `deploy` command.\nfunc NewCmdDeploy(fullName string, f *clientcmd.Factory, out io.Writer) *cobra.Command {\n\toptions := &DeployOptions{\n\t\tbaseCommandName: fullName,\n\t}\n\n\tcmd := &cobra.Command{\n\t\tUse: \"deploy DEPLOYMENTCONFIG [--latest|--retry|--cancel|--enable-triggers]\",\n\t\tShort: \"View, start, cancel, or retry a deployment\",\n\t\tLong: deployLong,\n\t\tExample: fmt.Sprintf(deployExample, fullName),\n\t\tSuggestFor: []string{\"deployment\"},\n\t\tRun: func(cmd *cobra.Command, args []string) {\n\t\t\tif err := options.Complete(f, args, out);

new\n\"main\" package. Even though it has to have a main() function to make cgo happy,\nthe main() function is ignored. Instead, put your startup code into the init()\nfunction which essentially takes on the same role as the module_register()\nfunction in C based plugins.\n\nThen, define a type which implements the Reader interface by implementing the\n\"Read() error\" function. In the example above, this type is called\nExamplePlugin. Create an instance of this type and pass it to RegisterRead() in\nthe init() function.\n\nBuild flags\n\nTo compile your plugin, set up the CGO_CPPFLAGS environment variable and call\n\"go build\" with the following options:\n\n export COLLECTD_SRC=\"\/path\/to\/collectd\"\n export CGO_CPPFLAGS=\"-I${COLLECTD_SRC}\/src\/daemon -I${COLLECTD_SRC}\/src\"\n go build -buildmode=c-shared -o example.so\n*\/\npackage plugin \/\/ import \"collectd.org\/plugin\"\n\n\/\/ #cgo CPPFLAGS: -DHAVE_CONFIG_H\n\/\/ #cgo LDFLAGS: -ldl\n\/\/ #include <stdlib.h>\n\/\/ #include <dlfcn.h>\n\/\/ #include \"plugin.h\"\n\/\/\n\/\/ int dispatch_values_wrapper (value_list_t const *vl);\n\/\/ int register_read_wrapper (char const *group, char const *name,\n\/\/ plugin_read_cb callback,\n\/\/ cdtime_t interval,\n\/\/ user_data_t *ud);\n\/\/\n\/\/ data_source_t *ds_dsrc(data_set_t const *ds, size_t i);\n\/\/\n\/\/ void value_list_add_counter (value_list_t *, counter_t);\n\/\/ void value_list_add_derive (value_list_t *, derive_t);\n\/\/ void value_list_add_gauge (value_list_t *, gauge_t);\n\/\/ counter_t value_list_get_counter (value_list_t *, size_t);\n\/\/ derive_t value_list_get_derive (value_list_t *, size_t);\n\/\/ gauge_t value_list_get_gauge (value_list_t *, size_t);\n\/\/\n\/\/ int wrap_read_callback(user_data_t *);\n\/\/\n\/\/ int register_write_wrapper (char const *, plugin_write_cb, user_data_t *);\n\/\/ int wrap_write_callback(data_set_t *, value_list_t *, user_data_t *);\n\/\/\n\/\/ int register_shutdown_wrapper (char *, plugin_shutdown_cb);\n\/\/ int wrap_shutdown_callback(void);\nimport \"C\"\n\nimport (\n\t\"context\"\n\t\"fmt\"\n\t\"unsafe\"\n\n\t\"collectd.org\/api\"\n\t\"collectd.org\/cdtime\"\n)\n\nvar (\n\tctx = context.Background()\n)\n\n\/\/ Reader defines the interface for read callbacks, i.e. Go functions that are\n\/\/ called periodically from the collectd daemon.\ntype Reader interface {\n\tRead() error\n}\n\nfunc strcpy(dst []C.char, src string) {\n\tbyteStr := []byte(src)\n\tcStr := make([]C.char, len(byteStr)+1)\n\n\tfor i, b := range byteStr {\n\t\tcStr[i] = C.char(b)\n\t}\n\tcStr[len(cStr)-1] = C.char(0)\n\n\tcopy(dst, cStr)\n}\n\nfunc newValueListT(vl *api.ValueList) (*C.value_list_t, error) {\n\tret := &C.value_list_t{}\n\n\tstrcpy(ret.host[:], vl.Host)\n\tstrcpy(ret.plugin[:], vl.Plugin)\n\tstrcpy(ret.plugin_instance[:], vl.PluginInstance)\n\tstrcpy(ret._type[:], vl.Type)\n\tstrcpy(ret.type_instance[:], vl.TypeInstance)\n\tret.interval = C.cdtime_t(cdtime.NewDuration(vl.Interval))\n\tret.time = C.cdtime_t(cdtime.New(vl.Time))\n\n\tfor _, v := range vl.Values {\n\t\tswitch v := v.(type) {\n\t\tcase api.Counter:\n\t\t\tif _, err := C.value_list_add_counter(ret, C.counter_t(v));

The output isn't 'perfect', but it's usually sufficiently readable\n\/\/ if the input already has sensible line breaks.\n\/\/\n\/\/ To quantify \"much faster\", on this one C file, `cmd\/dumbindent` in this\n\/\/ repository was 80 times faster than `clang-format`, even without a column\n\/\/ limit:\n\/\/\n\/\/ $ wc release\/c\/wuffs-v0.2.c\n\/\/ 11858 35980 431885 release\/c\/wuffs-v0.2.c\n\/\/ $ time dumbindent < release\/c\/wuffs-v0.2.c > \/dev\/null\n\/\/ real 0m0.008s\n\/\/ user 0m0.005s\n\/\/ sys 0m0.005s\n\/\/ $ time clang-format-9 < release\/c\/wuffs-v0.2.c > \/dev\/null\n\/\/ real 0m0.668s\n\/\/ user 0m0.618s\n\/\/ sys 0m0.032s\n\/\/ $ time clang-format-9 -style='{ColumnLimit: 0}' < release\/c\/wuffs-v0.2.c > \/dev\/null\n\/\/ real 0m0.641s\n\/\/ user 0m0.585s\n\/\/ sys 0m0.037s\n\/\/\n\/\/ Apart from some rare and largely uninteresting exceptions, the dumbindent\n\/\/ algorithm only considers:\n\/\/\n\/\/ ∙ '{' and '}' curly braces,\n\/\/ ∙ '(' and ')' round parentheses,\n\/\/ ∙ '\\n' line breaks,\n\/\/ ∙ ' ' spaces and '\\t' tabs that start or end a line, and\n\/\/ ∙ strings, comments and preprocessor directives (in order to ignore any of\n\/\/ the above special characters within them),\n\/\/\n\/\/ Everything else is an opaque byte. Consider this input:\n\/\/\n\/\/ for (i = 0; i < 3; i++) {\n\/\/ j = 0; \/\/ Ignore { in a comment.\n\/\/ if (i < j) { foo(); }\n\/\/ u = (v +\n\/\/ w);\n\/\/ }\n\/\/\n\/\/ From the algorithm's point of view, this input is equivalent to:\n\/\/\n\/\/ ....(.................).{\n\/\/ .................................\n\/\/ ...(.....).{....()..}\n\/\/ ....(...\n\/\/ .);\n\/\/ }\n\/\/\n\/\/ The formatted output (using the default of 2 spaces per indent level) is:\n\/\/\n\/\/ ....(.................).{\n\/\/ .................................\n\/\/ ...(.....).{....()..}\n\/\/ ....(...\n\/\/ .);\n\/\/ }\n\/\/\n\/\/ Dumbindent adjusts lines horizontally (indenting) but not vertically (it\n\/\/ does not break or un-break lines, or collapse consecutive blank lines),\n\/\/ although it will remove blank lines at the end of the input. In the example\n\/\/ above, it will not remove the \"\\n\" between \"u = (v +\" and \"w);\", even though\n\/\/ both lines are short.\n\/\/\n\/\/ Each output line is indented according to the net number of open braces\n\/\/ preceding it, although lines starting with close braces will outdent first,\n\/\/ similar to `gofmt` style. A line which starts ins a so-far-unbalanced open\n\/\/ parenthesis, such as the \"w);\" line above, gets 2 additional indent levels.\n\/\/\n\/\/ Horizontal adjustment only affects a line's leading white space (and will\n\/\/ trim trailing white space). It does not affect white space within a line.\n\/\/ Dumbindent does not parse the input as C\/C++ source code.\n\/\/\n\/\/ In particular, the algorithm does not solve C++'s \"most vexing parse\" or\n\/\/ otherwise determine whether \"x*y\" is a multiplication or a type definition\n\/\/ (where y is a pointer-to-x typed variable, such as \"int*p\"). For a type\n\/\/ definition, where other formatting algorithms would re-write around the \"*\"\n\/\/ as either \"x* y\" or \"x *y\", dumbindent will not insert spaces.\n\/\/\n\/\/ Similarly, dumbindent will not correct this mis-indentation:\n\/\/\n\/\/ if (condition)\n\/\/ goto fail;\n\/\/ goto fail;\n\/\/\n\/\/ Instead, when automatically or manually generating the input for dumbindent,\n\/\/ it is recommended to always emit curly braces (again, similar to `gofmt`\n\/\/ style), even for what would otherwise be 'one-liner' if statements.\npackage dumbindent\n\nimport (\n\t\"bytes\"\n)\n\n\/\/ 'Constants', but their type is []byte, not string.\nvar (\n\tbackTick = []byte(\"`\")\n\texternC = []byte(\"extern \\\"C\\\" {\")\n\tnamespace = []byte(\"namespace \")\n\tstarSlash = []byte(\"*\/\")\n\n\tnewLines = []byte(\"\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\")\n\tspaces = []byte(\" \")\n\ttabs = []byte(\"\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\")\n)\n\n\/\/ hangingBytes is a look-up table for updating the hanging variable.\nvar hangingBytes = [256]bool{\n\t'=': true,\n\t'\\\\': true,\n}\n\n\/\/ Options are formatting options.\ntype Options struct {\n\t\/\/ Spaces, if positive, is the number of spaces per indentation level.

In the example\n\/\/ above, it will not remove the \"\\n\" between \"u = (v +\" and \"w);\", even though\n\/\/ both lines are short.\n\/\/\n\/\/ Each output line is indented according to the net number of open braces\n\/\/ preceding it, although lines starting with close braces will outdent first,\n\/\/ similar to `gofmt` style. A line which starts ins a so-far-unbalanced open\n\/\/ parenthesis, such as the \"w);\" line above, gets 2 additional indent levels.\n\/\/\n\/\/ Horizontal adjustment only affects a line's leading white space (and will\n\/\/ trim trailing white space). It does not affect white space within a line.\n\/\/ Dumbindent does not parse the input as C\/C++ source code.\n\/\/\n\/\/ In particular, the algorithm does not solve C++'s \"most vexing parse\" or\n\/\/ otherwise determine whether \"x*y\" is a multiplication or a type definition\n\/\/ (where y is a pointer-to-x typed variable, such as \"int*p\"). For a type\n\/\/ definition, where other formatting algorithms would re-write around the \"*\"\n\/\/ as either \"x* y\" or \"x *y\", dumbindent will not insert spaces.\n\/\/\n\/\/ Similarly, dumbindent will not correct this mis-indentation:\n\/\/\n\/\/ if (condition)\n\/\/ goto fail;\n\/\/ goto fail;\n\/\/\n\/\/ Instead, when automatically or manually generating the input for dumbindent,\n\/\/ it is recommended to always emit curly braces (again, similar to `gofmt`\n\/\/ style), even for what would otherwise be 'one-liner' if statements.\npackage dumbindent\n\nimport (\n\t\"bytes\"\n)\n\n\/\/ 'Constants', but their type is []byte, not string.\nvar (\n\tbackTick = []byte(\"`\")\n\textern = []byte(\"extern \")\n\tnamespace = []byte(\"namespace \")\n\tstarSlash = []byte(\"*\/\")\n\n\tnewLines = []byte(\"\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\\n\")\n\tspaces = []byte(\" \")\n\ttabs = []byte(\"\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\\t\")\n)\n\n\/\/ hangingBytes is a look-up table for updating the hanging variable.\nvar hangingBytes = [256]bool{\n\t'=': true,\n\t'\\\\': true,\n}\n\n\/\/ Options are formatting options.\ntype Options struct {\n\t\/\/ Spaces, if positive, is the number of spaces per indentation level.

on Win7+, Debian 8+, Ubuntu 14.04+, OS X 10.6+, FreeBSD 11+)\n\/\/ and does not use any internal hardware IDs (no MAC, BIOS, or CPU).\n\/\/\n\/\/ Returned machine IDs are generally stable for the OS installation\n\/\/ and usually stay the same after updates or hardware changes.\n\/\/\n\/\/ This package allows sharing of machine IDs in a secure way by\n\/\/ calculating HMAC-SHA256 over a user

`dbus-uuidgen` and put the id into\n\/\/ `\/var\/lib\/dbus\/machine-id` and `\/etc\/machine-id`.\n\/\/ Windows users can use the `sysprep` toolchain to create images, which produce valid images ready for distribution.\npackage machineid \/\/ import \"github.com\/denisbrodbeck\/machineid\"\n\nimport (\n\t\"fmt\"\n)\n\n\/\/ ID returns the platform specific machine id of the current host OS.\n\/\/

(without admin privileges).\n\/\/\n\/\/ https:\/\/github.com\/denisbrodbeck\/machineid\n\/\/\n\/\/ https:\/\/godoc.org\/github.com\/denisbrodbeck\/machineid\/cmd\/machineid\n\/\/\n\/\/ This package is Cross-Platform (tested on Win7+, Debian 8+, Ubuntu 14.04+, OS X 10.6+, FreeBSD 11+)\n\/\/ and does not use any internal hardware IDs (no MAC, BIOS, or CPU).\n\/\/\n\/\/ Returned machine IDs are generally stable for the OS installation\n\/\/ and usually stay the same after updates or hardware changes.\n\/\/\n\/\/ This package allows sharing of machine IDs in a secure way by\n\/\/ calculating HMAC-SHA256 over a user provided app ID, which is keyed by the machine id.\n\/\/\n\/\/ Caveat: Image-based environments have usually the same machine-id (perfect clone).\n\/\/ Linux users can generate a new id with `dbus-uuidgen` and put the id into\n\/\/ `\/var\/lib\/dbus\/machine-id` and `\/etc\/machine-id`.\n\/\/ Windows users can use the `sysprep` toolchain to create images, which produce valid images ready for distribution.\npackage machineid \/\/ import \"github.com\/denisbrodbeck\/machineid\"\n\nimport (\n\t\"fmt\"\n)\n\n\/\/ ID returns the platform specific machine id of the current host
