- -## Version 1.2 (2014-06-03) - -Changes: - - - We switched back to a "rolling release". `go get` installs the current master branch again - - Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver - - Exported errors to allow easy checking from application code - - Enabled TCP Keepalives on TCP connections - - Optimized INFILE handling (better buffer size calculation, lazy init, ...) - - The DSN parser also checks for a missing separating slash - - Faster binary date / datetime to string formatting - - Also exported the MySQLWarning type - - mysqlConn.Close returns the first error encountered instead of ignoring all errors - - writePacket() automatically writes the packet size to the header - - readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets - -New Features: - - - `RegisterDial` allows the usage of a custom dial function to establish the network connection - - Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter - - Logging of critical errors is configurable with `SetLogger` - - Google CloudSQL support - -Bugfixes: - - - Allow more than 32 parameters in prepared statements - - Various old_password fixes - - Fixed TestConcurrent test to pass Go's race detection - - Fixed appendLengthEncodedInteger for large numbers - - Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo) - - -## Version 1.1 (2013-11-02) - -Changes: - - - Go-MySQL-Driver now requires Go 1.1 - - Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore - - Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors - - `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")` - - DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'. - - Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries - - Optimized the buffer for reading - - stmt.Query now caches column metadata - - New Logo - - Changed the copyright header to include all contributors - - Improved the LOAD INFILE documentation - - The driver struct is now exported to make the driver directly accessible - - Refactored the driver tests - - Added more benchmarks and moved all to a separate file - - Other small refactoring - -New Features: - - - Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure - - Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs - - Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used - -Bugfixes: - - - Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification - - Convert to DB timezone when inserting `time.Time` - - Splitted packets (more than 16MB) are now merged correctly - - Fixed false positive `io.EOF` errors when the data was fully read - - Avoid panics on reuse of closed connections - - Fixed empty string producing false nil values - - Fixed sign byte for positive TIME fields - - -## Version 1.0 (2013-05-14) - -Initial Release diff --git a/proxy_go/public/mysql@v1.6.0/LICENSE b/proxy_go/public/mysql@v1.6.0/LICENSE deleted file mode 100644 index 14e2f77..0000000 --- a/proxy_go/public/mysql@v1.6.0/LICENSE +++ /dev/null @@ -1,373 +0,0 @@ -Mozilla Public License Version 2.0 -================================== - -1.

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" - "time" - - _ "github.com/go-sql-driver/mysql" -) - -// ... - -db, err := sql.Open("mysql", "user:password@/dbname") -if err != nil { - panic(err) -} -// See "Important settings" section. -db.SetConnMaxLifetime(time.Minute * 3) -db.SetMaxOpenConns(10) -db.SetMaxIdleConns(10) -``` - -[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples"). - -### Important settings - -`db.SetConnMaxLifetime()` is required to ensure connections are closed by the driver safely before connection is closed by MySQL server, OS, or other middlewares. Since some middlewares close idle connections by 5 minutes, we recommend timeout shorter than 5 minutes. This setting helps load balancing and changing system variables too. - -`db.SetMaxOpenConns()` is highly recommended to limit the number of connection used by the application. There is no recommended limit number because it depends on application and MySQL server. - -`db.SetMaxIdleConns()` is recommended to be set same to (or greater than) `db.SetMaxOpenConns()`. When it is smaller than `SetMaxOpenConns()`, connections can be opened and closed very frequently than you expect. Idle connections can be closed by the `db.SetConnMaxLifetime()`. If you want to close idle connections more rapidly, you can use `db.SetConnMaxIdleTime()` since Go 1.15. - - -### 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 allowlist 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](https://dev.mysql.com/doc/en/cleartext-pluggable-authentication.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. - -##### `checkConnLiveness` - -``` -Type: bool -Valid Values: true, false -Default: true -``` - -On supported platforms connections retrieved from the connection pool are checked for liveness before using them. If the check fails, the respective connection is marked as bad and the query retried with another connection. -`checkConnLiveness=false` disables this liveness check of connections. - -##### `collation` - -``` -Type: string -Valid Values: -Default: utf8mb4_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`. - -The default collation (`utf8mb4_general_ci`) is supported from MySQL 5.5. You should use an older collation (e.g. `utf8_general_ci`) for older MySQL. - -Collations for charset "ucs2", "utf16", "utf16le", and "utf32" can not be used ([ref](https://dev.mysql.com/doc/refman/5.7/en/charset-connection.html#charset-connection-impermissible-client-charset)). - - -##### `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 rejected 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, preferred, -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) or use `preferred` to use TLS only when advertised by the server. This is similar to `skip-verify`, but additionally allows a fallback to a connection which is not encrypted. Neither `skip-verify` nor `preferred` add any reliable security. You can use a custom TLS config after registering it 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'` - * [`transaction_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_transaction_isolation): `SET transaction_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: -``` -user:password@unix(/cloudsql/project-id:region-name: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 explicitly allowed by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the allowlist 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 equivalent 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). - - -### Unicode support -Since version 1.5 Go-MySQL-Driver automatically uses the collation ` utf8mb4_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/8.0/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.
