You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then. - -Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name) as `dataSourceName`: -```go -import "database/sql" -import _ "github.com/go-sql-driver/mysql" - -db, err := sql.Open("mysql", "user:password@/dbname") -``` - -[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples"). - - -### DSN (Data Source Name) - -The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets): -``` -[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN] -``` - -A DSN in its fullest form: -``` -username:password@protocol(address)/dbname?param=value -``` - -Except for the databasename, all values are optional. So the minimal DSN is: -``` -/dbname -``` - -If you do not want to preselect a database, leave `dbname` empty: -``` -/ -``` -This has the same effect as an empty DSN string: -``` - -``` - -Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct. - -#### Password -Passwords can consist of any character. Escaping is **not** necessary. - -#### Protocol -See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available. -In general you should use an Unix domain socket if available and TCP otherwise for best performance. - -#### Address -For TCP and UDP networks, addresses have the form `host[:port]`. -If `port` is omitted, the default port will be used. -If `host` is a literal IPv6 address, it must be enclosed in square brackets. -The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form. - -For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`. - -#### Parameters -*Parameters are case-sensitive!* - -Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`. - -##### `allowAllFiles` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files. -[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html) - -##### `allowCleartextPasswords` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network. - -##### `allowNativePasswords` - -``` -Type: bool -Valid Values: true, false -Default: true -``` -`allowNativePasswords=false` disallows the usage of MySQL native password method. - -##### `allowOldPasswords` - -``` -Type: bool -Valid Values: true, false -Default: false -``` -`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords). - -##### `charset` - -``` -Type: string -Valid Values: -Default: none -``` - -Sets the charset used for client-server interaction (`"SET NAMES "`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`). - -Usage of the `charset` parameter is discouraged because it issues additional queries to the server. -Unless you need the fallback behavior, please use `collation` instead. - -##### `collation` - -``` -Type: string -Valid Values: -Default: utf8_general_ci -``` - -Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail. - -A list of valid charsets for a server is retrievable with `SHOW COLLATION`. - -##### `clientFoundRows` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed. - -##### `columnsWithAlias` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example: - -``` -SELECT u.id FROM users as u -``` - -will return `u.id` instead of just `id` if `columnsWithAlias=true`. - -##### `interpolateParams` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`. - -*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!* - -##### `loc` - -``` -Type: string -Valid Values: -Default: UTC -``` - -Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details. - -Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter. - -Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`. - -##### `maxAllowedPacket` -``` -Type: decimal number -Default: 4194304 -``` - -Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*. - -##### `multiStatements` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded. - -When `multiStatements` is used, `?` parameters must only be used in the first statement. - -##### `parseTime` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string` -The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`. - - -##### `readTimeout` - -``` -Type: duration -Default: 0 -``` - -I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*. - -##### `rejectReadOnly` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - - -`rejectReadOnly=true` causes the driver to reject read-only connections. This -is for a possible race condition during an automatic failover, where the mysql -client gets connected to a read-only replica after the failover. - -Note that this should be a fairly rare case, as an automatic failover normally -happens when the primary is down, and the race condition shouldn't happen -unless it comes back up online as soon as the failover is kicked off. On the -other hand, when this happens, a MySQL application can get stuck on a -read-only connection until restarted. It is however fairly easy to reproduce, -for example, using a manual failover on AWS Aurora's MySQL-compatible cluster. - -If you are not relying on read-only transactions to reject writes that aren't -supposed to happen, setting this on some MySQL providers (such as AWS Aurora) -is safer for failovers. - -Note that ERROR 1290 can be returned for a `read-only` server and this option will -cause a retry for that error. However the same error number is used for some -other cases. You should ensure your application will never cause an ERROR 1290 -except for `read-only` mode when enabling this option. - - -##### `serverPubKey` - -``` -Type: string -Valid Values: -Default: none -``` - -Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN. -Public keys are used to transmit encrypted data, e.g. for authentication. -If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required. - - -##### `timeout` - -``` -Type: duration -Default: OS default -``` - -Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*. - - -##### `tls` - -``` -Type: bool / string -Valid Values: true, false, skip-verify, -Default: false -``` - -`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig). - - -##### `writeTimeout` - -``` -Type: duration -Default: 0 -``` - -I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*. - - -##### System Variables - -Any other parameters are interpreted as system variables: - * `=`: `SET =` - * `=`: `SET =` - * `=%27%27`: `SET =''` - -Rules: -* The values for string variables must be quoted with `'`. -* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed! - (which implies values of string variables must be wrapped with `%27`). - -Examples: - * `autocommit=1`: `SET autocommit=1` - * [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'` - * [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'` - - -#### Examples -``` -user@unix(/path/to/socket)/dbname -``` - -``` -root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local -``` - -``` -user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true -``` - -Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html): -``` -user:password@/dbname?sql_mode=TRADITIONAL -``` - -TCP via IPv6: -``` -user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci -``` - -TCP on a remote host, e.g. Amazon RDS: -``` -id:password@tcp(your-amazonaws-uri.com:3306)/dbname -``` - -Google Cloud SQL on App Engine (First Generation MySQL Server): -``` -user@cloudsql(project-id:instance-name)/dbname -``` - -Google Cloud SQL on App Engine (Second Generation MySQL Server): -``` -user@cloudsql(project-id:regionname:instance-name)/dbname -``` - -TCP using default port (3306) on localhost: -``` -user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped -``` - -Use the default protocol (tcp) and host (localhost:3306): -``` -user:password@/dbname -``` - -No Database preselected: -``` -user:password@/ -``` - - -### Connection pool and timeouts -The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively. - -## `ColumnType` Support -This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported. - -## `context.Context` Support -Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts. -See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details. - - -### `LOAD DATA LOCAL INFILE` support -For this feature you need direct access to the package. Therefore you must change the import path (no `_`): -```go -import "github.com/go-sql-driver/mysql" -``` - -Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)). - -To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore. - -See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details. - - -### `time.Time` support -The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program. - -However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter. - -**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes). - -Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`. - - -### Unicode support -Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default. - -Other collations / charsets can be set using the [`collation`](#collation) DSN parameter. - -Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default. - -See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support. - -## Testing / Development -To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details. - -Go-MySQL-Driver is not feature-complete yet.

This is different from libpq, which does not allow +run-time parameters in the connection string, instead requiring you to supply +them in the options parameter. + +For compatibility with libpq, the following special connection parameters are +supported: + + * dbname - The name of the database to connect to + * user - The user to sign in as + * password - The user's password + * host - The host to connect to. Values that start with / are for unix + domain sockets. (default is localhost) + * port - The port to bind to. (default is 5432) + * sslmode - Whether or not to use SSL (default is require, this is not + the default for libpq) + * fallback_application_name - An application_name to fall back to if one isn't provided. + * connect_timeout - Maximum wait for connection, in seconds. Zero or + not specified means wait indefinitely. + * sslcert - Cert file location. The file must contain PEM encoded data. + * sslkey - Key file location. The file must contain PEM encoded data. + * sslrootcert - The location of the root certificate file. The file + must contain PEM encoded data. + +Valid values for sslmode are: + + * disable - No SSL + * require - Always SSL (skip verification) + * verify-ca - Always SSL (verify that the certificate presented by the + server was signed by a trusted CA) + * verify-full - Always SSL (verify that the certification presented by + the server was signed by a trusted CA and the server host name + matches the one in the certificate) + +See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING +for more information about connection string parameters. + +Use single quotes for values that contain whitespace: + + "user=pqgotest password='with spaces'" + +A backslash will escape the next character in values: + + "user=space\ man password='it\'s valid'" + +Note that the connection parameter client_encoding (which sets the +text encoding for the connection) may be set but must be "UTF8", +matching with the same rules as Postgres. It is an error to provide +any other value. + +In addition to the parameters listed above, any run-time parameter that can be +set at backend start time can be set in the connection string.

The same marker can be reused for the same parameter: + + rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1 + OR age BETWEEN $2 AND $2 + 3`, "orange", 64) + +pq does not support the LastInsertId() method of the Result type in database/sql. +To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres +RETURNING clause with a standard Query or QueryRow call: + + var userid int + err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age) + VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid) + +For more details on RETURNING, see the Postgres documentation: + + http://www.postgresql.org/docs/current/static/sql-insert.html + http://www.postgresql.org/docs/current/static/sql-update.html + http://www.postgresql.org/docs/current/static/sql-delete.html + +For additional instructions on querying see the documentation for the database/sql package. + + +Data Types + + +Parameters pass through driver.DefaultParameterConverter before they are handled +by this package. When the binary_parameters connection option is enabled, +[]byte values are sent directly to the backend as data in binary format. + +This package returns the following types for values from the PostgreSQL backend: + + - integer types smallint, integer, and bigint are returned as int64 + - floating-point types real and double precision are returned as float64 + - character types char, varchar, and text are returned as string + - temporal types date, time, timetz, timestamp, and timestamptz are + returned as time.Time + - the boolean type is returned as bool + - the bytea type is returned as []byte + +All other types are returned directly from the backend as []byte values in text format. + + +Errors + + +pq may return errors of type *pq.Error which can be interrogated for error details: + + if err, ok := err.(*pq.Error); ok { + fmt.Println("pq error:", err.Code.Name()) + } + +See the pq.Error type for details. + + +Bulk imports + +You can perform bulk imports by preparing a statement returned by pq.CopyIn (or +pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement +handle can then be repeatedly "executed" to copy data into the target table. +After all data has been processed you should call Exec() once with no arguments +to flush all buffered data. Any call to Exec() might return an error which +should be handled appropriately, but because of the internal buffering an error +returned by Exec() might not be related to the data passed in the call that +failed. + +CopyIn uses COPY FROM internally. It is not possible to COPY outside of an +explicit transaction in pq. + +Usage example: + + txn, err := db.Begin() + if err != nil { + log.Fatal(err) + } + + stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age")) + if err != nil { + log.Fatal(err) + } + + for _, user := range users { + _, err = stmt.Exec(user.Name, int64(user.Age)) + if err != nil { + log.Fatal(err) + } + } + + _, err = stmt.Exec() + if err != nil { + log.Fatal(err) + } + + err = stmt.Close() + if err != nil { + log.Fatal(err) + } + + err = txn.Commit() + if err != nil { + log.Fatal(err) + } + + +Notifications + + +PostgreSQL supports a simple publish/subscribe model over database +connections. See http://www.postgresql.org/docs/current/static/sql-notify.html +for more information about the general mechanism. + +To start listening for notifications, you first have to open a new connection +to the database by calling NewListener. This connection can not be used for +anything other than LISTEN / NOTIFY. Calling Listen will open a "notification +channel"; once a notification channel is open, a notification generated on that +channel will effect a send on the Listener.Notify channel. A notification +channel will remain open until Unlisten is called, though connection loss might +result in some notifications being lost. To solve this problem, Listener sends +a nil pointer over the Notify channel any time the connection is re-established +following a connection loss. The application can get information about the +state of the underlying connection by setting an event callback in the call to +NewListener. + +A single Listener can safely be used from concurrent goroutines, which means +that there is often no need to create more than one Listener in your +application. However, a Listener is always connected to a single database, so +you will need to create a new Listener instance for every database you want to +receive notifications in. + +The channel name in both Listen and Unlisten is case sensitive, and can contain +any characters legal in an identifier (see +http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS +for more information). Note that the channel name will be truncated to 63 +bytes by the PostgreSQL server. + +You can find a complete, working example of Listener usage at +https://godoc.org/github.com/lib/pq/example/listen. + +*/ +package pq diff --git a/vendor/github.com/lib/pq/encode.go b/vendor/github.com/lib/pq/encode.go new file mode 100644 index 0000000..a6902fa --- /dev/null +++ b/vendor/github.com/lib/pq/encode.go @@ -0,0 +1,602 @@ +package pq + +import ( + "bytes" + "database/sql/driver" + "encoding/binary" + "encoding/hex" + "errors" + "fmt" + "math" + "strconv" + "strings" + "sync" + "time" + + "github.com/lib/pq/oid" +) + +func binaryEncode(parameterStatus *parameterStatus, x interface{}) []byte { + switch v := x.(type) { + case []byte: + return v + default: + return encode(parameterStatus, x, oid.T_unknown) + } +} + +func encode(parameterStatus *parameterStatus, x interface{}, pgtypOid oid.Oid) []byte { + switch v := x.(type) { + case int64: + return strconv.AppendInt(nil, v, 10) + case float64: + return strconv.AppendFloat(nil, v, 'f', -1, 64) + case []byte: + if pgtypOid == oid.T_bytea { + return encodeBytea(parameterStatus.serverVersion, v) + } + + return v + case string: + if pgtypOid == oid.T_bytea { + return encodeBytea(parameterStatus.serverVersion, []byte(v)) + } + + return []byte(v) + case bool: + return strconv.AppendBool(nil, v) + case time.Time: + return formatTs(v) + + default: + errorf("encode: unknown type for %T", v) + } + + panic("not reached") +} + +func decode(parameterStatus *parameterStatus, s []byte, typ oid.Oid, f format) interface{} { + switch f { + case formatBinary: + return binaryDecode(parameterStatus, s, typ) + case formatText: + return textDecode(parameterStatus, s, typ) + default: + panic("not reached") + } +} + +func binaryDecode(parameterStatus *parameterStatus, s []byte, typ oid.Oid) interface{} { + switch typ { + case oid.T_bytea: + return s + case oid.T_int8: + return int64(binary.BigEndian.Uint64(s)) + case oid.T_int4: + return int64(int32(binary.BigEndian.Uint32(s))) + case oid.T_int2: + return int64(int16(binary.BigEndian.Uint16(s))) + case oid.T_uuid: + b, err := decodeUUIDBinary(s) + if err != nil { + panic(err) + } + return b + + default: + errorf("don't know how to decode binary parameter of type %d", uint32(typ)) + } + + panic("not reached") +} + +func textDecode(parameterStatus *parameterStatus, s []byte, typ oid.Oid) interface{} { + switch typ { + case oid.T_char, oid.T_varchar, oid.T_text: + return string(s) + case oid.T_bytea: + b, err := parseBytea(s) + if err != nil { + errorf("%s", err) + } + return b + case oid.T_timestamptz: + return parseTs(parameterStatus.currentLocation, string(s)) + case oid.T_timestamp, oid.T_date: + return parseTs(nil, string(s)) + case oid.T_time: + return mustParse("15:04:05", typ, s) + case oid.T_timetz: + return mustParse("15:04:05-07", typ, s) + case oid.T_bool: + return s[0] == 't' + case oid.T_int8, oid.T_int4, oid.T_int2: + i, err := strconv.ParseInt(string(s), 10, 64) + if err != nil { + errorf("%s", err) + } + return i + case oid.T_float4, oid.T_float8: + // We always use 64 bit parsing, regardless of whether the input text is for + // a float4 or float8, because clients expect float64s for all float datatypes + // and returning a 32-bit parsed float64 produces lossy results. + f, err := strconv.ParseFloat(string(s), 64) + if err != nil { + errorf("%s", err) + } + return f + } + + return s +} + +// appendEncodedText encodes item in text format as required by COPY +// and appends to buf +func appendEncodedText(parameterStatus *parameterStatus, buf []byte, x interface{}) []byte { + switch v := x.(type) { + case int64: + return strconv.AppendInt(buf, v, 10) + case float64: + return strconv.AppendFloat(buf, v, 'f', -1, 64) + case []byte: + encodedBytea := encodeBytea(parameterStatus.serverVersion, v) + return appendEscapedText(buf, string(encodedBytea)) + case string: + return appendEscapedText(buf, v) + case bool: + return strconv.AppendBool(buf, v) + case time.Time: + return append(buf, formatTs(v)...) + case nil: + return append(buf, "\\N"...) + default: + errorf("encode: unknown type for %T", v) + } + + panic("not reached") +} + +func appendEscapedText(buf []byte, text string) []byte { + escapeNeeded := false + startPos := 0 + var c byte + + // check if we need to escape + for i := 0;
